Arches in openings have been used for a long time, as it was believed that this architectural opening is very aesthetic. Today, the arrangement of arches in doorways has become popular due to the fact that they are easy to install from plasterboard. With the advent of plasterboard arches, it became possible to separate rooms without having to special effort. Such arched vaults will help give each room its individuality.

Thanks to the arch you can visually expand small space corridor, kitchen or room.

As for arch shapes, there are a large variety of them. By making arches from plasterboard, you can recreate almost any historical copy. The main convenience is that drywall is very flexible material. We make an arch in the doorway according to the following scheme:

1. All done necessary measurements and counted required amount material.
2. Next, everything is prepared necessary tools that will be required for the job.
3. The front parts of the arches are cut out, and a frame is made from a profile or wood.
4. Next, the front elements of the arches are attached.
5. The lower parts of the arches are cut out and also attached.
6. The arched corners are attached and all surfaces are puttied.

What materials will be needed?

To work you will need following materials and tools:

Types of arch shapes.

• plasterboard 9.5 mm thick;
• guide profiles - 27x28 mm;
• rack profiles - 60x27 mm;
• self-tapping screws for fastening gypsum plasterboard (plasterboard sheet) - 3.5x25 mm;
• dowels with screws - 6x60 mm for fastening the profile frame (needed if the walls are made of brick or concrete).
• self-tapping screws with a press washer - 4.2x12 mm;
• wood screws (if the walls are made of wood);
• putty on gypsum board;
• needle roller for bending plasterboard sheets;
• arched corner with perforation;
• putty knife;
• screwdriver;
• protective gloves;
• roulette;
• square;
• pencil;
• metal scissors;
• stationery knife for cutting plasterboard.

What type of arch can it be?

The opening of a door or window can be decorated by creating an arch. Exists a large number of arches that you can make in your home. When choosing, you need to be guided not only by taste preferences, but also by the following parameters: first of all, the height of the ceiling and the width of the doorway. So, some designs look good with high ceilings, while others, on the contrary, look good with low ceilings. Kinds:

Diagram of the arch structure.

1. Portal - this arch is made in the standard form of the letter P. The design of the arch can be different: polygonal or wavy. It all depends on the available materials and the imagination of the home owner.
2. Classic arch - otherwise called “classic”. This type arches are only suitable for ceilings whose height is more than 3 m in height. On average, with an opening width of 90 cm, about 45 cm of height will be occupied by the bend of the arch, so a height of 2.5 m may not be enough.
3. Romance. This option is perfect for wide openings that are relatively small in height. Between rounded corners, a straight insert is made, either at an angle or horizontally.
4. Modern. This type is perfect for making a doorway inside standard apartment. In this case, the corners can be either rounded or sharp.
5. Half-arch. This option can perfectly perform room zoning.
6. A straight arch is an excellent option for rooms designed in high-tech and modern styles.

In addition, the arches differ in their design:

1. Radial (asymmetric) is the simplest and at the same time cheapest technology that will suit absolutely any interior.
2. Multi-level. This design is used mainly in cases where the interior is made in one specific style.
3. Openwork is suitable for all cases, except when the walls are made in a non-standard form.
4. Domed and symmetrical are suitable for classic arches, the opening of which is at least 1 m.

Doorway: taking the necessary measurements

Methods for bending a sheet of drywall: dry and wet.

Before making an arch in a doorway, you need to take all the necessary measurements. Naturally, you need to start with measuring the opening. You need to find out the height and width of the opening.

As for the width of the arch, it should be equal to the distance between the opposite walls of the doorway. It is necessary to measure this distance and divide it in half. This size is needed in order to make an accurate semicircle.

In addition, you need to determine the shape of the future arch in advance. If you choose a classic arch, then you need to level all the walls. They should be completely vertical so that the arch does not look awkward. You need to level the walls using beacons using putty or plaster.

Preparing gypsum boards for an arch

1. First of all, you will need a regular pencil and a tight rope. The pencil is tied to a string and you get an excellent wide-scale compass.
2. Next, the middle is marked on the plasterboard - that is, the radius of the future arch. To do this, you need to remember the size of the opening width.
3. Where the top of the arch will be, a mark of 60-65 cm is marked. This figure was taken based on a radius of 50 cm and a height of 10-15 cm above the arch.
4. Next, the plasterboard sheet is cut exactly to the width of the doorway.
5. After which a point is marked that will be the center of the radius.
6. Take a rope with a pencil, its length should be equal to the radius. A semicircle is drawn along a pre-marked point. By doing correct measurements You should get a perfect circle, which will be the arch of the opening.
7. After that, take a stationery knife or jigsaw, with which you need to cut out a semicircle along the drawn line. In our case, its width should be 100 cm and its height 60-65 cm.

DIY arch frame installation

Both the aesthetics and the strength of the structure will depend on a well-executed frame.

The stages of manufacturing and installation of the frame are as follows:

1. First of all, a guide made of a metal profile is attached at the top of the opening using dowels. Next, the guides are attached to the wall in 2 places.
2. After this, an arched profile is made, also from metal. To make it, using metal scissors, identical cuts are made in the profile, each of which then needs to be bent to form right angle. As a template, you can use already made parts from gypsum plasterboard. The profile is fastened with dowels, and the drywall is fastened with self-tapping screws. For the arch you will need 2 arched profiles.
3. To strengthen the frame, you need to attach sections of the profile between the 2 arcs.
4. Next, the arc-shaped parts are attached to the frame using self-tapping screws.

If you need to renovate your apartment, then perhaps you will need information on how to make an arch, and do it yourself at home beautifully and correctly, without the help of builders. Recently, such interior elements have attracted more and more attention. The door is removed, and the opening itself is designed in the form of an arch, which can have a wide variety of, sometimes bizarre, shapes.

Arched doorway of unusual shape

Apartment options for arched openings

The owners can pursue several goals: create a common space, expand the room, create a light and elegant design, and so on. If you wish, you should buy a ready-made arch from the construction department; in extreme cases, put in a little effort and devote a little time to create an original and interesting option, which will definitely be exclusive.

The arch has gained extraordinary popularity

To improve the passage from room to room without using a door, it is not at all necessary to call a hired team of craftsmen. By choosing the right type and format of the building, you can easily do everything yourself. It is equally important to wisely choose the materials that will be used to create this element. The step-by-step instructions below will tell you how to do everything as correctly as possible and avoid common mistakes.

Different types of arches have some differences in design, which affects their further installation. The main differences lie in the supports of the structure.

It is worth noting that interior openings are not load-bearing. Therefore, it is important to choose an arch based on the appropriate parameters.

Beautiful arch between rooms

Arched opening, which is used instead regular door, made from several materials. Now we're talking about specifically about the frame of the entire structure:

• a metal profile on which plasterboard sheets (GKL) are mounted on top;
• wooden blocks with a cross section of 20-30 mm.

This type of arch will easily hold its own and total weight along with the finishing. The main task here is reliable and rigid fastening to the walls. This will protect the elements and remain in place in their original form for more than one year.

If we are talking about a private house or apartment, then an open arch is used only as decorative element. But the entire load-bearing load in this design option is transferred to the side concrete walls or to the lintel above the structure itself.

Possible types of arches and features of each of them

Before you make an arch with your own hands at home, you need to choose a form of construction that will look beautiful and correct in the future. The most common forms are:

• classical;
• romantic;
• modern;
• ellipsoid;
• trapezoidal;
• portal.

Strict arch portal

The arched opening of a classical shape is based on a regular semicircle. But the portal arch consists of strict rectangular outlines. Other varieties are derivatives of these two main varieties. In addition, there can be asymmetry using only one support on the side. Or the form may be completely unthinkable.

The most common form of openings

The choice of shape and finish of the future arch should be chosen based on the overall design of the room, so that it fits harmoniously into the interior. For example, a semicircular arch will fit perfectly into. The following parameters must initially be taken into account:

• ceiling height;
• dimensions of the doorway;
• individual features of the apartment.

You must understand that one living space looks great with a classic arch, and a portal will harmoniously fit into the second. But here it all depends on the personal preferences of the owners.

Arch in Art Nouveau style

1. A classic arch will look great where the ceiling is over 3 meters high.
2. Art Nouveau design - perfect option for panel apartment building and design of the entrance to the kitchen;
3. A romantic with wide supports frames the entrance from the corridor to the hall well;
4. Portal structures fit into the interior with clear lines (both vertically and horizontally). They are well suited for installation in beautiful houses from wooden beams or logs.

Material selection

To quickly create an arched opening, you can buy a ready-made kit for creating an arch in the store. But this option is not suitable for everyone due to the rather high price. And their appearance is not very different from each other. However, selecting the right model can reach a dead end due to the difference in the parameters of the opening and the future structure.

The main components of the arch

Most often for self-made purchase the following materials:

• drywall;
• plywood sheets.

The winner is drywall, which is lightweight and quite easy to work with. Another advantage is that plasterboard sheets are easy to finish with many finishing materials. And plywood lends itself better to bending.

Finishing an arched doorway

To create the frame part, use:

• wooden blocks with a cross section of 20*20 mm and 30*30 mm;
• metallic profile.

As an option: you can create similar structures from brick, concrete, or aerated concrete. The only thing left to do on top is to give it a neat appearance. But not everyone will like it. After all, such an interior is an indicator of wealth and status. It is also necessary to take into account the weight of such a structure. If the floors are old and fragile, then this type of arch should be folded back.

Metal frames are rarely used not only because of the additional weight, but also because of their considerable cost. If you want to build an arch complex shape, then you must understand that doing this on your own will be very difficult. To construct an arch with your own hands, it is better to choose drywall and a suitable profile.

Step-by-step creation of an arch with your own hands

Below are photos and step-by-step descriptions of the entire process, with the help of which it will be much easier for you to make your masterpiece in the doorway. Initially, you need to take care of creating the frame part. And only after that start covering it and finishing it. The main thing is to be as attentive and careful as possible. Then your idea will be realized in the best possible way.

Plasterboard arch (diagram)

Before you begin installing the arch, you need to properly prepare the doorway.

1. The door leaf and frame of the old door need to be removed.
2. Expand the opening to the dimensions required for installation work.
3. You should not plaster the cut walls on which the structure frame will be installed. In any case, they will be blocked by the casing. You just need to level the edges and dismantle pieces of old building materials (plaster, concrete particles, falling bricks).
4. The main task is to create a base and securely attach the frame to it. This requires that it be in a vertical position. Tilts are not allowed.
5. If the arch will have lighting or backlighting, then the wiring is carried out before installation work begins.
6. Measurements are taken not at one, but at several points of the opening. When the walls are not perfect, you should choose the widest part of the opening. This will be the width of the structure.
7. A template on cardboard will help make markings easier. This way you can identify what is necessary and avoid making mistakes. Moreover, you will be able to see on the spot what the future arch will look like.

Important! Don't forget that the arched opening at the top absorbs about 15 cm of the total height. The minimum distance between the arch and the ceiling should be 20 cm. This information is entered during preliminary calculations.

The arch reduces the height of the doorway

Construction load-bearing frame - important stage, because it will support the entire arch structure.

Fastening the sheathing to the frame

To bend drywall, use dry or wet method. For the first one, you will need a jigsaw to carefully make the cuts. For the second, it is better to use a needle roller to quickly and evenly wet the panel. Using self-tapping screws, the cut out elements of the arch are installed in their places. The final stage is plastering and finishing with the selected material.

Finished arch

You now know how to make an arch with your own hands at home, and you can design it beautifully and correctly. The main thing is to use your imagination and choose, but do not forget to follow the dimensions and assembly instructions exactly. And in the video below you will find the entire process of creating an arch.

Often the builder is faced with the task of building an arched ceiling, arranging a domed roof or an original “humpbacked” bridge over a pond, which is becoming an increasingly popular small architectural form. At the same time, in most cases, masters do not bother themselves with complex calculations, using two quantities that are known even to a seventh grader. These values ​​are the width of the span, subsequently covered by the arch, and the height of the rise of the arch, which is calculated by determining the distance between an imaginary horizontal line drawn between the points at which the arch is supported and the highest point of the arch. According to experts, these values ​​are not enough to build a reliable arch with high performance characteristics. The main role in the design of an arched ceiling is given to the choice of materials from which the arch will be constructed, and the associated calculation of the arch, the correctness of which determines its subsequent performance characteristics. By following these recommendations, you can design a reliable arched ceiling that will become great solution and not only diversifies the design of the apartment, but also becomes an excellent decoration landscape design garden Specialists in this field will easily carry out everything necessary calculations, but what to do if it is not possible to use their services and you have to do all the work yourself? In this case, use our recommendations that will help you cope with the task as efficiently as possible.

Arch systems from a professional's point of view

From the point of view of engineering specialists, arched structures are systems of a broken or curved nature, the supporting elements of which are subject to vertical loads, leading to inclined reactions directed into the opening. The horizontal component of such a support reaction is the thrust, which indicates that arched systems are thrust structures. This is their main difference from beams, which experience only normal mechanical stress. IN modern construction arches are used as main load-bearing structures structures for various purposes, be it utility, industrial or agricultural buildings, with a span of 12 to 70 m. As for foreign construction, in this industry the design of arched spans is even more developed, which makes it possible to construct arches with a height of up to 100 m or more.

Classification of arches: main varieties

According to static circuit , distinguish hingeless , double-hinged And three-hinged arches ;

Also, the supporting ends of the arch can be connected by a horizontally located rod that takes up the horizontal load and is called puff . The calculation of an arch with a tie is somewhat different from the calculation of a two-hinged arch or a three-hinged arch without a tie.

Each of these types has its own advantages and disadvantages, and therefore the choice of design is made by a design engineer who will calculate the three-hinged arch taking into account the strength requirements for it, the materials used for its construction, and the architectural tasks assigned for one design or another.

In accordance with the support scheme, there are arches with tightening And arches without tightening . If the former perceive the thrust, then the thrust of the latter is transmitted to the supports. The tightening is made from profile steel or reinforcement. If the arch is used in conditions aggressive environments that contribute to metal corrosion, the use of glued wooden puffs is allowed.

According to the form they are distinguished:

• Triangular arches consisting of straight semi-arches. Calculating a triangular arch is not difficult, and you can do it yourself;

• Pentagonal arches;
• Segmental arches, the axes of the semi-arches are located on a common circumference;
• Pointed arches, consisting of several semi-arches, the axes of which are located on two circles;

How to calculate a three-hinged arch with a tightening: recommendations from experts

If you are planning to install a small arch, calculations and design will not cause you any particular difficulties, since for their production it is preferable to use sheets of building material of huge sizes, such as plywood, plasterboard or OSB boards. The largest indicators of their length and width are 250 and 120 cm, respectively, which allows you to simply draw an arch on a sheet of material and cut out at least two component parts of the load-bearing beams. Finally, such arches are sheathed sheet material, after which we can assume that the arch is ready. Despite the speed and simplicity of installing arches using this method, it also has its own disadvantages, including a large amount of material wasted on waste, the decorative nature of the finished arch, and the inability of the structure to bear loads.

The arrangement of arched structures becomes significantly more complicated if the master is faced with the task of installing an arch over a large clearance (up to several meters) or an arch that can withstand the highest loads. Due to the fact that on construction market It is difficult to find materials whose dimensions allow for the installation of such an arch; it is designed as a stacked structure consisting of several parts. In this regard, the master is faced with the task of accurately calculating the arch and determining the dimensions of its parts.

As mentioned earlier, arches are distinguished according to parameters such as shape, size and height, and before implementing a project for calculating a wooden arch, it is necessary to clearly understand the design and approximate dimensions of the desired arch. Taking into account these parameters, it is easier to decide on the choice of materials for its installation and subsequent calculations.

Amateurs often get scared when they hear the phrase “arch calculation,” but the calculations in this case are simple and are based on the use of school formulas from geometry. In addition, to facilitate calculations, it is necessary to draw the outline of the arch on a slightly reduced scale on graph paper. After this, an arch template is made in real size, having which you will be able to most effectively carry out further calculations, since you will be able to attach a so-called copy of the arch to the place of its installation and evaluate the correctness of the calculations made. To make a template, you can use thick cardboard, plywood or a sheet of fiberboard.

Arched structures occupy a vast niche in architecture, and their use is a very broad topic that cannot be covered in one article. In this material, we will look at making an arch in an apartment or private house, since a traditional rectangular opening, designed in the form of an arch, will become an exclusive detail of the apartment’s interior, distinguishing it from other apartments.

Let's consider an example of calculating a three-hinged arch:

In most cases, regardless of the experience of the master, he knows three parameters of the arch, including the width of the span covered by the arch, the height of the arch, and the depth (width) of the wall. The master is faced with the task of calculating the parameters of the arch parts, assembling them into a single arched structure and firmly securing it.

Method number 1 - empirical

Although any calculation of an arch begins with calculating the radius of its circumference, an arch does not always represent an arc of a circle. There are situations when the arch consists of two arches (this applies to arches made in gothic style) or are characterized by asymmetrical outlines. In this case, each arc of the arch is calculated separately. But, let's return to calculating the circumference of the arch. It is more convenient to produce it on paper, while reducing the size, on a scale, for example, 1: 50. Having prepared the paper and a compass, draw a doorway on a sheet taking into account the scale and draw an axis of symmetry dividing the opening in half. After this, the axis of the compass must be changed by placing the leg with the needle directly on the axis of symmetry. Next, you need to draw several arcs and, having chosen the most optimal one, remove the rest using an eraser.

To demonstrate more clearly this example, let's draw the arc of the arch:

where R is the radius of the circumference of the arch, and L represents half the chord of the arch, while the size of the chord corresponds to the length of the arch clearance. As for H, this indicator reflects the height of the arch.

Method number 2 - mathematical

To carry out a mathematical calculation of the radius of the circle of an arch, use the Pythagorean theorem, according to which:

R= L2 + (R2 - H2)

R= L2 + (R - H)2

Having expanded the binomial, we transform the expression into the form:

R2 = L2 + R2 - 2HR + H2

Subtract R from both sides and get:

L2 + H2 - 2HR = 0

Let's move the term with R beyond the equal sign:

2RH = L2 + H2

And finally, we get the desired R:

R = (L2 + H2)/ 2H

Important! Formula for calculating the radius of an arch's circumference: R = (L2 + H2)/ 2H , where R is the radius of the arch circumference, H is the height of the arch, L is half the chord of the arch (the length of the arch clearance).

Due to the fact that the arch consists of several parts, for the manufacture of which you will have to use a board of a certain width, we will calculate the dimensions of the part that can be made from a board with specific dimensions. To do this, it is necessary to solve the inverse problem. Taking into account the known radius of the arch and the height of its rise (in this case, this is the width of the board), we will calculate the maximum possible length of the part that can be made from a board with a certain width, that is, we will calculate the length of the arch. Due to the fact that we already know certain relationships from previous calculations, we derive the following formula:

L2 = 2RH - H2

HR-H2

To properly make an arch, you need to prepare a few more parts, taking into account the fact that they will have to be joined during the installation process. The joining method is selected depending on the purpose of the arch. It is practiced to use overhead parts along the “cheeks” of the arch and join two arches, taking into account the shift by half the part.

In the process of calculating the parts, it is necessary to take into account which side of the arch, depending on its location in relation to the parts, interests us most (internal or external). Simply put, we need to understand how the load-bearing parts of the arch will be located in relation to the arch itself. For example, when installing a domed roof, the load-bearing parts of the arched structure will be located below the arch, and when installing an arched vault - above. Situations arise when it is necessary to arrange a double-sided arch. In the latter case, the calculation of the arch parts will be based on the smallest rounding.

If during operation the arch will bear high loads, it is necessary to strengthen it with the help of various beams and tie rods installed between the arch nodes. Thus, you can equip a load-bearing truss that can withstand increased loads.

If you decide to arrange an arch in the Gothic style, you need to determine the radius of curvature of the arch at the ends as accurately as possible. In this case, you will make your task easier by using an empirical method for calculating an arch, with which you will experimentally select the rounding point of the arch, then from this point downwards draw a line running parallel to the wall, measure the resulting distance and draw a line of the same length on the other side. Then the leg of the compass is placed on this line, the distance (radius) is determined and, moving down or up parallel to the line, the point is determined where the line of the wall and the arc of the arch will close through the second (smaller) arc. On the second side of the drawing you need to do the same.

To make your task easier and calculate the arch as efficiently as possible, you can make several drawings and choose the most suitable one. As you already understand, the given examples of arch calculation are far from the only ones, and there are other methods of calculation, but the empirical method clearly shows you what the arch will look like after installation. In addition, during the calculation process, you can easily adjust the drawing until you achieve the desired result.

Having made the drawing and made sure that it is correct, you need to make an arch template, using which you can easily install any arched structure.

A few words about choosing material for the arch

To make an arch, you can use various materials, including metal (calculation metal arch is produced somewhat differently), as well as brick and concrete, but the simplest and cheapest way is to make an arch from plasterboard. Due to the fact that an arch made of brick and concrete will be very heavy, it is necessary to install reinforcement cage. The reinforcement is easy to bend, and you can easily weld a frame from it. After this, using a hammer drill, you need to drill holes in the walls, drive pins into them and weld the arched frame to them.

Making an arch from plasterboard is much easier and faster, however finished design will be less durable than its brick or concrete counterparts. To do this, it is necessary to make a frame from tin profiles, cover them with plasterboard on the sides, and use segments to cover the internal opening (to make them, the plasterboard is cut on one side, bent and finally secured with self-tapping screws). The resulting edges must be smoothed with putty.

Calculation of a brick arch: main points

To calculate a brick arch, it is also necessary to make a template from fiberboard, the quality of which largely determines the performance characteristics and appearance of the future brick arch. First of all, it is necessary to calculate the dimensions of the template, which will require knowledge of the width of the arched opening. For example, the width of the arched opening is 15,000 mm.

Since the width of the template should be 5 mm less, it means it will be 1495 mm. Even if the template swells from moisture, you can easily dismantle it at the final stages of work. The height of the template should correspond to the height of the arch; in our case, let it be 168 mm. Since the whole face brick It is recommended to place it at the top of the arch; it is necessary to calculate the number of bricks. Since the height of one row is about 72 mm (brick height + joint height), and the total number of rows is 4, the arched height is 72 * 4 - 120 = 168 mm. (120mm is the height of the brick laid on edge).

In conclusion

Most often, the installation of arched structures is carried out for decorative design premises, regardless of its purpose. This could be a house, an apartment, or an office.

Often, an arch is used to decorate the doorway between the kitchen and living room. However, arch installation can also be used in larger types of construction. If you plan to decorate the interior of a room using an arch, experts recommend making an arched structure from plasterboard, as this is much cheaper, simpler and less labor-intensive. At the same time, the finished structure is in no way inferior to arches made of brick or wood. In order not to be disappointed in the beauty and correctness of the arch, experts recommend approaching the installation of the arched structure with due care and calculating the arch, which can be done in several ways. In our article, we have offered you the two most common and effective methods for calculating an arch, using which you can build a reliable and aesthetically attractive arch.

You can make an arch in a doorway in various ways. Each of them is selected based on a specific situation. It is necessary to take into account the construction skills possessed House master, as well as financial opportunities.

It is worth noting that it is possible to qualitatively install an arch in a doorway with your own hands only when all the features of this design are taken into account. The fact is that this finishing option has its pros and cons.

The advantages include the following aspects:

• Visual increase in space. In this case, two factors are combined at once. The first is that an opening without a door unites two rooms, this erases some existing border. The second is based on the shape of the structure.
• An excellent option for zoning. Indeed, an arch can be an excellent solution to the problem of dividing a single area.
• Nice decorative look. This design can decorate any interior. It should be borne in mind that the overall design must be harmoniously thought out.

We must not forget about the existing shortcomings. They consist in the fact that the feature of this product is openness, since there is no door leaf. Therefore, there is a complete lack of sound insulation and the penetration of foreign odors, if we are talking about the border with the kitchen area.

When designing an arch, you should think about the fact that the feeling of security will disappear

Existing options

What is special about installing an arch in a doorway? The point is that there are different kinds of these designs:

1. Ellipse. This configuration is considered to be classic. It is made round. All transitions are very smooth.
2. Round. This option allows you to expand the opening. This method is suitable for cases where zoning is required.
3. Trapezoid. Assumes the absence of rounded areas.

Arch - various types of structures

On a note! You can often hear that an arch and a portal are two different architectural element. In fact, the portal is the most simple solution arched design. It is made in the form of a rectangle, sometimes supplemented with rounded corners.

Features of the construction of arches

You can make an arch in several ways, but you need to take into account the height of the openings.

For low openings

This method of creating an arch involves pre-marking the surface. The marked area is cut out (hollowed).

The general technology is as follows:

• The opening is being dismantled. The old box is removed. Part of the crumbling plaster is removed.
• Height is determined future design. Lines are drawn along two vertical sides. They must be equal and made exactly at the specified height.
• To obtain the radius of the arch, the existing width is measured. This value is divided in half.
• Between vertical posts held horizontal line. It should be located at a level that will correspond to the beginning of the rounding.
  

  On a note! It is important to consider that the distance to the ceiling should not be less than 30 cm.

• The center is marked on the drawn line. The self-tapping screw is screwed in. A cord is attached to the screw, which must be equal to a given radius. A pencil is attached to the end of the rope. This tool marks the bend.
• Trimming is done according to the existing markings. If the wall is strong enough, then chiselling is performed. To make the work easier, pre-drilling is done.

It is necessary to comply with the requirements for the construction of the arch

Thus, the required shape is obtained. Next, you should process it carefully. This is done by grinding. The resulting structure is treated with putty or plaster. They can serve as final finishing material.

For high openings

The door arch can also be made in another way. It consists in the fact that plasterboard and a metal profile are used as the main material. The technology assumes that everything will be done along an existing opening. The following actions are performed:

On a note! The created sheathing should be recessed to the thickness of the gypsum plaster boards used. Minor errors may occur. They can be easily corrected with plaster.

On a note! If you need to install an arch very quickly, the best solution would be to use a ready-made structure. These products are made from various materials and have standard configurations.

After all the procedures, an almost finished design is obtained. All you need to do is install a fragment of a gypsum plasterboard that will close the open arc-shaped space. The procedure is performed as follows:

1. The bending section is measured.
2. The resulting size is transferred to the drywall.
3. The required fragment is cut out.
4. This part needs to be bent. To do this, it is cut from the wrong side into strips.
5. Carefully place into place and secure.

Finished plasterboard arch

The completed design requires additional decorative finishing. It should be noted that drywall makes it quite easy to create an arch with your own hands. If you use wood as a material, you must have sufficient experience to correctly process and install such a product.

GCR boards are used as substitutes fibreboards, plywood.

Plywood is often used to create arched openings instead of drywall.

There are some tips that will help you get a beautiful arched opening:

• The general appearance of the arch should correspond to the interior design.
• To get more original design- it is drawn up with different sides individually.
• Existing communications should be laid in advance.

Summarizing the above, it can be noted that there are various ways to make a door arch. You just need to be patient and adhere to certain rules and recommendations. Then everything will definitely work out.

Most interior designers consider interior arches to be an established classic of the genre; the arched vaults of doorways have long since seriously replaced the slightly angular rectangle of a classic door. Passages and openings between rooms remain as original bridges, uniting islands of residential premises that are different in meaning and content with no less important kitchen, bathroom and toilet. If possible, why not make the interior openings no less beautiful and comfortable.

How practical are interior arches?

Often, anyone who wants to build interior arches doubts how practical and convenient such structures are in everyday use. The idea of ​​​​building arched arched openings has existed for several hundred years; back in the 50s of the last century, many interior and corridor openings with arches were built various configurations, until the fashion for saving and a utilitarian approach to interior design finally buried a wonderful idea.

The manufacture of interior arches will require certain financial and time costs in connection with the alteration of part of the doorway. But most often, owners decide to remodel, since the end result fully justifies the costs:

The appearance is significantly improved, even the simplest interior arch looks much more attractive and interesting than the official version of a rectangular door opening;

The space of an apartment or house visually becomes more spacious, even in small apartments with miniature kitchens and tiny corridors, the room becomes brighter;

Heat exchange and air movement between rooms improves by an order of magnitude. Fresh air doesn't leak through ventilation ducts, moves without interference and restrictions along the shortest path.

In most cases, owners decide to change the shape and size of the interior opening and install an arch above the doorway in order to improve the appearance internal space living rooms. Only a few years later it is discovered that installing an arch and modifying the interior opening makes it possible to improve the conditions for distributing heat throughout the house in winter and coolness in the summer heat. And most importantly, without laying an additional complex pipe system.

Types of arches

One of the most valuable qualities of an interior arch is the good adaptability of the updated doorway to any interior of rooms and corridors. Door arches made in the form of frames from steel profile And wooden slats, bricks and gypsum blocks. For external finishing of the surface of the walls and ceiling adjacent to the arch and frame of the interior opening, plasterboard sheets, panels, polyurethane foam, plywood and fiberboard sheets.

For doorways and interior passages of standard width, up to 90 cm inclusive, an arch with a support frame can be purchased in a specialized salon. Such standard arched vaults are most often cast from polypropylene or assembled by hand from wooden blanks.

Round arches

Most often, an arched vault over an interior doorway is associated with the classic round arch, which is most common in the architecture of stone buildings and structures. It is the round arch that is most often chosen for a doorway.

Artist-designers and residential interior developers use about a dozen basic configurations of round interior arches with supports on the doorway frame.

To get the ideal arc of an interior arch, the galvanized profile is divided into sectors, the side shelf is cut and the metal strip is bent according to a pre-planned template.

For your information! The round arch is very popular, primarily due to its simple installation technology.

IN classic version a round interior arch is made in the shape of a sector in ¾ of a circle or ½ of a circle; often the shape and curvature of its arc can be supplemented by side elements of any shape and configuration, but always symmetrical.

If it is necessary to add oriental motifs to the design of the interior arch, then the profile of the arched span is made in the form of two intersecting arcs. In this design, the interior arch takes on an almond-shaped profile.

Interior arch can be combined with supporting columns, most often with elements of stucco or imitation of the style of the Victorian era.

If necessary, for example, if the size of the doorway is relatively small, the arch can be decorated without any columns or unnecessary decor. It is enough to emphasize the line of the arched arc and close decorative overlays the plane of transition to the walls.

If the dimensions of the corridor allow, the design of the interior doorway can be designed in the form of one round arch. Instead of the standard rectangular door frame only a small rounded outline remains, marking the boundary between the kitchen, living rooms and a corridor.

Round arches are used in cases where an apartment or living space in a private house is built in the form of several small rooms. Full-size round arches very successfully visually unite the rooms into one studio apartment. To save behind the bedroom, kitchen or personal account private character, the interior opening with an arch is closed with double doors or a light sliding door.

A rather interesting solution is shown in the photo below.

One design of an interior opening uses a round or annular arch and a rectangular box. A stylish doorway makes it possible to add several very necessary details to the interior of the room and open the adjacent room or corridor to light and air.

If the ceiling height is more than 2.5 m, and the dimensions of the interior passage are more than two meters, you can use the widespread technique of dividing the space into several sectors.

In this case, the design of the interior opening in the form of two small arches of a classical shape with an intermediate column provides best quality ventilation and light filling.

For low ceilings the round arch is divided into several elements or replaced with a rectangular doorway.

Rectangular arches

Arched structures of rectangular or square shape are no different in their characteristics and functions from the classic round arch. A rectangular shape is used if the interior of the apartment contains a significant number of objects and parts with straight lines.

In the vast majority of cases, a rectangular shape for an interior arch is chosen in a situation where valuable types of wood, plastic and a monotonous rectilinear design are actively used in interior decoration.

For example, an interior doorway between the corridor and the living room can be designed as wood panels, assembled into one arched structure. On the one hand, there is enough air and light, on the other hand, the boundary between two rooms that are completely different in meaning and function is clearly marked.

Rectangular arches are simpler and more technologically advanced to manufacture; installation does not require the use of special marking devices, as in the case of constructing semicircular and round arched structures.

Arches in the shape of an ellipse

It is not always possible to build a doorway with an arch in the form of a perfect semicircle or segment of a circle. There are certain restrictions on the distance from the ceiling to the top point of the arched arc; for apartment premises this distance should be at least 40 cm.

In such cases, the arch arch is made in the form of a horizontal semi-ellipse. The excess of the arched arc is smaller, and the entire structure of the fashionable interior opening fits freely within the dimensions of the rooms and the height of the ceilings of a standard apartment layout.

Using a diagram with a horizontal ellipse, you can build a fairly wide passage between adjacent rooms according to the diagram shown in the photo.

The ellipse is ideal as a profile for building an interior passage. For example, you can create an opening in the form of a vertical ellipse with truncated edges.

The passage itself turns out to be wide enough to use it, but due to the narrowing of the sides towards the top and bottom, the cross-section is smaller than that of a standard rectangular profile or a classically shaped arch. Therefore, in order to increase the amount of air and light through the interior opening, the passage contour is supplemented with side windows.

Trapezoidal arches

The design of an arch in the shape of a trapezoid can be considered a natural continuation of the rectangular design. Traditionally, door and interior openings with trapezoidal top part used in attic rooms, especially if the ceiling of the room is made with side slopes.

The trapezoidal shape ensures increased stability of the upper transverse beam of the opening, which is why such structures are widely used in houses made of timber and rounded logs.

The decorative qualities of the trapezoid are lower than those of interior openings with an arch in the shape of an ellipse or rectangle. However, there is a demand for a passage in the form of a trapezoid arch, especially in panel projects for suburban and country houses. In any case, an interior doorway with a trapezoid-shaped arch looks much more interesting than a boring rectangular design.

Figured arches

Manufacturing an arched vault of complex shape is in a good way show the talents of an interior designer, imagination and invention. The most in a simple way build original arch non-standard shape What remains is the addition of several curved lines and surfaces to the classic arched arc.

For example, if you add a couple of side arches to a simple symmetrical arch, you can get a fairly expressive line of an arched vault for an interior wall.

A small addition to the standard arch or semi-ellipse of several asymmetrical elements turns the arch into a stylish interior opening.

Figured arches, as a rule, are made according to complex curvilinear patterns, for example:

The process of designing and manufacturing a figured interior arch is quite complex for an amateur, so even the simplest multi-level openings, as a rule, require the knowledge and skills of a professional designer artist.

Interior arches made of plasterboard

In the process of planning a figured arch, you always have to look for a suitable assembly method and the material from which it is easiest to assemble a fairly complex arched structure.

Most home arched interior openings are built from wood and drywall. Sheets of pressed gypsum are perfectly processed, cut, drilled, painted and puttied.

The basis plasterboard arch assembled in the form of a frame made of galvanized profile. Sturdy corner and U-shaped profile made of sheet metal can be used as load-bearing element strong frame or bend it in an arc of any curvature.

The process of making an interior arch is as follows:

• The frame is assembled using rivets and attached to the walls and ceiling of the interior opening;
• The base is sewn up with sheets of plasterboard;
• Seams and cracks are filled with gypsum putty;
• Curved surfaces are sanded, painted and finished.

The arched interior opening is light, durable and of any complexity in structure and design.

Interior arches made of wood

Arched interior openings made of wood and its imitation firmly occupy second place in the popularity of designs. Beam and slats made of valuable species It is very difficult to technologically bend wood to the required radius, so almost all interior arched openings made of wood are built in a rectangular shape.

The exception is wooden arches self made, very beautiful, with carvings and elements of furniture decor. Often the arc is cut from solid wood and lined with veneer made from valuable wood species.

For your information! A handmade arch can be easily distinguished by microdefects in the surface and the characteristic texture of the veneer, while cheap interior arches made of polypropylene look perfectly smooth and one-color.

Arch finishing

Depending on the materials used to build the frame of the interior opening, the most suitable type is selected finishing. Plasterboard structures must be primed and puttied, after which the surface of the arch can be covered with polyvinyl chloride film with a texture like wood, red brick or natural stone.

A simpler finishing method involved using decorative plaster or wall graphics. The corner joints of interior arches can be covered with polyurethane tiles to look like artificial stone.

Wooden arches are finished using furniture technology:

• The surface of the wood is primed, tinted and varnished;
• The finishing coating is applied to match the colors of the walls and ceilings of the rooms adjacent to the interior opening;
• The veneered surfaces of doorways with arches are always varnished, followed by polishing of the decorative layer of wood.

If finishing operations are carried out in accordance with polishing standards, the decorative layer of wood can last at least 20 years, while plasterboard finishing will last a maximum of 10-15 years.

Illuminated arch

Installing flashlights and lighting remains one of the most popular ways to enhance decorative effect from the arch.

The lanterns can be installed along the contour of the arch, or placed in the upper part of the arched arc and covered with translucent polycarbonate.

Instead of spotlights can be used LED strips, monochrome or color.

Interior of interior arches

The most difficult stage of planning an interior arch is the development general style, because the doorway must correspond to at least two rooms at the same time. For example, the passage from the living room to the kitchen is best decorated in light colors. White color, creamy and beige shades They are considered universal, capable of combining with almost any style of interior of the living room or kitchen.

Arch in the living room

All other interior arches leading from the living room to other rooms are designed in the style of the interior of the main space of the apartment.

Before planning the shape and dimensions of the arched structure, you will need to take into account the color and texture of the furniture in the living room and the pattern of the flooring.

The concept of designing an arch in a living room is extremely simple - interior openings should visually expand the size of the room, even if this requires removing half of the internal adjacent wall.

Arch in the hallway and corridor

A similar technique is used when planning arched openings in the hallway. The corridor area experiences the greatest load from dust and dirt brought into the apartment from the street or entrance.

Therefore, the entrance part of the apartment is planned in more muted colors; accordingly, arched structures are made with minimal absorption of space.

An exception may be interiors with extensive use of wooden panels, parquet and precious wood trim. In this case, a massive interior arch, decorated in mahogany, can serve as a kind of bridge from the more utilitarian and stuff-filled hallway of the room to the central part of the apartment or house.

Arch to the kitchen instead of a door

Today, interior openings between the kitchen and the living room firmly occupy first place in the list of the most popular solutions for redevelopment of old apartments. It just so happens that in the vast majority of apartments old building The living room is connected to the kitchen by a long and narrow corridor.

It is very inconvenient, so the hall is connected to the kitchen area by a wide and spacious opening with a round arch. IN budget option an interior arch can be made from plasterboard sheets finished with decorative plaster.

A more complex and at the same time non-standard option for arranging an interior opening is shown in the photo below.

Instead of one passage, two symmetrical figured passages with round arches and an asymmetrical opening shape were built in the adjacent wall. High ceilings allow you to make an arched part with a certain degree of widening. As a result central part the walls remain used for the installation of a TV and furniture, and the side sectors are “donated” for the arrangement of the arch.

Arch in the children's room

In apartments with a small living area, using an interior arch solves the problem of dividing and delimiting space into the territory of adults and children.

If a room is allocated for several children, then with the help of an arch it is possible to resolve most disputes related to the division of the territory. Arched structures are used quite rarely for arranging a doorway.

Arch in the bedroom

For the rest room and bedroom, the color of the walls, the shape and style of the arch are selected in strict accordance interior decoration and the interior of the room.

As a rule, double-leaf doors with an arched vault or small-sized interior arches with a monotonous design of the walls and ceiling space are used for the bedroom.

Conclusion

Arched structures have long won the hearts of apartment and house owners seeking to improve and improve the layout and interior of their home. The interior arch remains one of the most affordable, simple and at the same time very effective ways make the interior of the rooms brighter and fresher. Moreover, the manufacturing process is not so complicated and intricate, and most of the work can be done with minimal costs. You only need a little skill as an artist-designer, the rest should be entrusted to design professionals.
