Hire construction team of 2-3 people costs about 300 rubles per hour. The cost of construction materials from the contractor will be 20-30% higher than at a retail point, not to mention wholesale warehouses. It is generally better to remain silent about the conscientiousness of the work. Why not then make a canopy from a metal profile with your own hands and save money and nerves?

Preparatory earthworks and selection of materials

In order for the construction process to be successful and nothing to be redone later, it is necessary to immediately take into account all the nuances. This applies to both selection the right materials, clearing the territory, and engineering work to calculate the maximum load. Let's consider the sequence of actions.

Step 1 It is necessary to select a construction site.

If you have several options where you can build future design, then it is better to give preference to a place with shallow clay in order to save on concrete. You should also take into account the angle of the ground so that your building does not end up in a place where water collects from the entire site - this will provide you with a lot of inconvenience, regardless of why you built it. It is best to choose a hill or relatively flat area with the ability to drain water.

Step 2 We choose the material.

It is immediately necessary to calculate the cost of the future design. If you use galvanized metallic profile for the roof or painted by powder coating, then the cost will be considerable. If you just buy metal and treat it with anti-corrosion protection, you can save up to 30%. The size of the metal square for the racks must be calculated taking into account the rainfall load per 1 m2 on your territory + wind impact factor (about 3.4% for moderate climate zone). With a size of 4x4 meters and a slope of no more than 45 0, a metal square measuring 40x40 millimeters will suffice. The greater the distance between the supports, the greater their thickness should be.

Step 3 Clearing the area for action.

The floor of the canopy will be concrete, so it is necessary to remove about 10 centimeters of earth from its location, fill it halfway with sand, a little crushed stone and leave about 5 centimeters for concrete screed. This will be enough for a car weighing 1200-1800 kg. If there are heavy objects in the canopy, it is better to make the screed 9-12 centimeters. During the cleaning process, we remove all roots from the ground and large stones.

Step 4 We build communications.

Before you build a canopy from corrugated sheets with your own hands, you need to think about its subsequent operation. The first step is to make ebbs in the ground, calculate their location and other details. In some areas, it is necessary to take into account the availability of electricity, water supply, and gas supply (depending on the purpose for which this structure is being built).

Now that we already have a “master development plan” in hand, we can proceed directly to construction. It is better to check everything at once, since any alteration will cost you very much or take a lot of time.

Installing supports and sheathing

The manufacture of a supporting structure is the most important process, since the durability of the structure directly depends on the correct execution of all actions. An incorrectly assembled frame may simply fall under heavy load. winter time or be unkempt in appearance. To prevent this from happening, everything must be done gradually, taking into account all possible situations during operation.

Step 1 Installation of columns.

The first step is to drill holes in the ground with a diameter of 30 centimeters - they will be intended for subsequent concreting of metal supports. Next, we insert a support into them, only carefully so as not to pour a lot of earth onto the bottom of the hole - the concrete may then sag. After you pour 50% of the solution into the hole, you need to take a plumb line, measure everything and adjust the stand left/right. Carry out exactly the same operation with the three remaining supports, and then level them in height.

Step 2 We make the strapping.

It can be done at the very top - this traditional method construction, or you can try out extraordinary ways to strengthen the structure. For example, weld the harness crosswise (the top of one support and the bottom of the other are connected), with a mesh, or even make it double - at the top and bottom.

Step 3 Lathing.

If you have a direct pitched roof– there is no need to fool yourself and come up with “cunning” designs. Simply install metal beams every 80 centimeters, and a profiled profile will be screwed onto them. a metal sheet. With a gable roof it is a little more complicated: we make a straight beam and a ridge; under the ridge there should be perpendicular reinforcement to the straight beam. One boost is enough. Most difficult option– double arch. Here it will be easier to buy ready-made bent elements, and then make L-shaped reinforcements between these arched squares every 40-50 centimeters. If the canopy is more than 4 meters wide, additional direct reinforcement must be installed.

Do-it-yourself canopies made from corrugated sheets will cost about 7,000 rubles if you buy metal at the average market price. The installation process will take no more than 1 day, and only 1 worker can complete it (you must be able to use a little welding machine and basic skills in working with grinding tools).

Preparing the roof

This is the most important process, since the appearance of the entire structure depends on the quality of assembly. We will attach it to a bolted connection - it’s much easier this way. To prevent the roof from leaking, as well as to avoid corrosion of bolts and metal profiled sheets, it is better to use plastic or rubber washers that fit directly onto the cap and can protect the hole from moisture in winter. Let's take a closer look step by step instructions for roof installation.

IN country house you can’t do without various canopies that are ideal for relaxation, economic needs or car parking. When using a metal profile, which has high strength and durability, the structure will last for decades. But before using corrugated sheeting for a canopy, you need to familiarize yourself with its characteristics.

Application of metal profiles

Metal profiles are well suited for the construction of canopies for both commercial and recreational purposes. Recreational ones are used as protection from the sun and wind over swimming pools and playgrounds.

A utility shed is being built at the site summer kitchen, storing household equipment or parking a car. The canopy structure can be free-standing or an extension of the house. In the first case, the canopy is erected on separate supports, and in the second, one or two sides rest on the wall of the house.

Single-pitch canopy

Easiest to install - lean-to canopy. When erecting it, one row of supports is lower than the second, which is why the sheet of metal profile is mounted at an angle. Due to this roof design, the snow flows down without any hindrance.

There are other types of metal profile structures: gable, arched. In the first case, it will be more difficult to construct the frame and select more sheets of metal profiles to cover the roof. A gable canopy is often used to protect a large area from wind and rain. It is more resistant to adverse weather conditions.

To complete an arched canopy, you will need to use the services of professionals. It is quite difficult to make an arched structure yourself. Therefore, lean-to sheds are often installed.

Corrugated sheets in quality roofing material often chosen due to its advantages:

• Environmentally friendly.
• Durability.
• UV resistance.
• Resistance to low temperatures.
• Durability.
• Strength.
• Reasonable price.
• Easy to care for.
• Fire safety.

In addition to all the advantages, corrugated sheeting can be easily installed with your own hands. You can build the structure without outside help, but provided that the canopy is small in size. A canopy made of metal profiles can transform the exterior of a house if its installation is carried out competently.

Most manufacturers offer a ready-made kit for assembling a canopy. It is enough to understand the finished drawings and assemble the frame using them. But this option will cost more than assembling a frame from separate profile pipes. In the case of the latter option, you will have to spend time selecting and trimming supports.

Canopy drawing

In order to make a canopy from a metal profile with your own hands, you should make a drawing. It is compiled based on the dimensions of the structure: width, length, height. You need to decide which side will be higher and which lower. If the structure rests on the wall of the building, then the supporting side will be higher. And from it, sheets of metal profiles will be attached at an angle to the racks.

• Number of racks.
• Number of lags.
• Farm design.
• Number of corrugated sheets.

To do this, you need to draw the future design on a sheet of paper, based on which it will be easier to calculate the amount of materials.

Design

The metal profile canopy has the following design:

• Metal ones are installed support pillars.
• The pillars of each row are tied with rectangular profile pipes (beams).
• To add strength to the structure, jibs - rectangular profile pipes - are installed between the piping pipe and the post.
• A triangular truss structure is installed on the pillars.
• Logs are installed across the trusses, which have the shape of rectangular pipes.
• Sheets of metal profiles are mounted on the logs.

All elements are connected to each other with bolts.

Required tools and materials

Materials for work you will need:

• Corrugated sheeting (grades such as NS35 or NS44 are used).
• Steel round pipes(for supports).
• Rectangular profile pipes (for the frame).
• Concrete.
• Sand.
• Fastening elements (screws and bolts).
• Primer.
• Dye.

To perform the work you will need to purchase the following tools:

• Roulette.
• Pencil.
• Building level.
• Drill.
• Screwdriver.
• Hammer.
• Bulgarian.
• Spanners.
• Brush.

It is better to purchase all materials of high quality, which will ensure reliable fastenings. This affects not only the strength of the product, but also the appearance of the canopy. After this, you can begin installing the canopy.

Do-it-yourself canopy for a house made of metal profiles. Step-by-step instruction

When all the materials for work are ready, you can begin installing the canopy. The assembly technology consists of several stages:

• Preparations.
• Frame assemblies.
• Roof coverings.
• Checking the structure for strength.

Before starting installation, you must complete preparatory work.

Preparatory work

At the initial stage, the site for construction should be prepared. To do this, the area is cleared of debris and vegetation. The site must be leveled and the soil compacted. Then the marking is carried out: using a tape measure, marks are made for the location of the pillars. Places should be marked with pegs, between which a rope should be pulled. Then holes are dug 1 m deep (for a large structure 1.5 m).

To determine the depth of the holes, you need to be guided not only by the weight of the structure, but also by the depth of soil freezing.

The next stage of preparation is cutting the pipes. If round pipes are used as supports, the diameter must be at least 80 mm. Optimal length– 3000 mm. It is also necessary to prepare pieces of pipes with a diameter of 83 mm.

The cut parts of 83 mm pipes are placed in the prepared holes. 80 mm pipes are inserted into them. It is necessary to pay attention to the fact that the support should not be visible from the cut short pipe. Then the support with the cut pipe must be connected with bolts. Ready design you need to insert it into the hole, fill it with sand and fill it with concrete. Leave for 1 week for the mixture to dry.

Frame installation

When the concrete mixture has dried, you can begin assembling the frame. To do this, each row of pillars is tied with profile pipes. Such beams are secured with bolted connections. The levelness of the installation must be constantly checked building level. If the pillars different sizes, then they should be filed, and then continue working.

Then the strength of the structure should be increased. To do this, jibs are installed - metal profiles that connect support pillars and beams.

They need to be mounted at an angle of 45 0.

Then the installation phase of the supporting truss structure begins. It is mounted on beams. This design will strengthen the canopy, allowing it to withstand heavy loads.

The truss is a triangle, in the center of which profiles are installed in a zigzag direction. To make a truss correctly, it is necessary to carry it out according to the drawings. Trusses are installed every meter.

Logs are mounted perpendicularly on top of the truss ( rectangular pipes). All elements are connected with bolts. After assembling the structure, it is necessary to check the strength of all connections. If necessary, more reliable protection must be provided.

The finished structure must be coated with a layer of primer and then painted. This will extend its service life. When the paint is completely dry, you can install metal profile sheets. Installation starts from bottom to top.

It is necessary to ensure that the area of ​​the canopy roof exceeds the area of ​​the platform between the supports.

The sheets must be secured with self-tapping screws. It is necessary to perform at least 8 fastenings for one sheet. The first row of metal profile sheets is laid overlapping. The second row is installed end to end with the first row. But all the sheets of the second row are overlapped relative to each other.

In order for the design to be of high quality, you must follow the advice of professionals:

• Determine the depth of soil freezing in order to dig a hole of the required depth. Otherwise, the structure may tilt over time.
• To make a roof at an angle, you need to adjust the angle by the difference in the lengths of opposite supports.
• In order to prevent unevenness, the soil should be carefully leveled and compacted.
• Use quality fasteners. Self-tapping screws must be used with rubber gaskets, otherwise damage may occur on the material.
• Be sure to prime all metal elements. This will protect the structure from corrosion.
• Lay the sheets overlapping.
• The metal profile does not need to be coated protective layer. The material is coated with a special paint that is resistant to adverse weather conditions.

You can see the installation of the metal profile in this video. Recommendations from installation experts are provided.

If you install the structure in accordance with all the requirements, it will please the eye of its owner for many years. Metal profiles as a roofing material are the best option, because it is distinguished not only by durability, but also by good appearance. Do not forget that when constructing a canopy made of metal profiles, it is recommended to use high-quality materials.

An important part of the exterior country house is a canopy. It is designed to protect part of the yard from precipitation and ultraviolet rays, and also performs a decorative function. Small area, covered with material on top, are sheds attached to the house. Photos of similar structures can be seen in this review. In this case, the supports of the structure are displayed on the desired height. Attaching to the main structure involves attaching one side of the structure to the wall of the house.

The hanging structure allows you to create a magnificent relaxation area on fresh air

Sheds attached to the house can be made with your own hands. The photo shows the main stages of installation. The frame of the structure is often made of profiled pipe or timber. This structure is adjacent to the wall and takes on the load from the snow accumulated on the roof.

The roof is usually covered with corrugated sheets, slate or galvanized material. The metal for the frame structure has ductility and strength. It is suitable for different styles registration Such structures can be erected with your own hands.

The wood frame system combines well with other materials. Wood suits most architectural designs. Before use, this material should be treated with protective agents. Polycarbonate canopies attached to the house are becoming increasingly popular, photos of which can be viewed on the Internet.

Polycarbonate is easy to assemble and comes in a variety of colors

Polycarbonate enjoys the following advantages:

• plastic is characterized by durability. Mechanical impact is not scary for him;
• light weight of the material;
• polycarbonate transmits light well;
• flexibility of the canvas.

Helpful information! By purchasing a design kit for self-assembly, it is necessary to check the integrity and strength of all connections.

Sheds attached to the house: photos and design features

Sheds attached to the house, as shown in the photo, can be of two types. These are cantilever models and awnings on supports. The console version can be of any length, but its width should not be more than two meters. Support structures can be used for various purposes.

Awnings can have different purposes:

• awnings for car protection;

• various awnings: with posts, retractable or basket.

Homeowners often choose wood sheds. Such structures have an excellent set of characteristics:

• are distinguished by ease of construction;
• can withstand long stays outdoors, especially when processed correctly;
• characterized by safety for human health;
• have an affordable price.

Helpful information! For comfortable use of the canopy, it is worth taking care of the installation of light and lighting fixtures.

Options for canopies attached to a house made of corrugated sheets: photos and design features

An awning made of corrugated sheets can be made in various configurations. Single-pitch, gable and arched structures are created from corrugated sheets. In addition, a structure made from this material has the following features:

• ease of manufacture;
• saving money;
• long service life.

Important! A canopy made of corrugated sheets is mounted only with galvanized self-tapping screws that have a rubber seal.

Creating a Project

When choosing a design project, it is worth deciding on the following parameters:

• dimensions and purpose of the structure;
• plot size;
• snow and wind loads;
• snow depth and expected annual precipitation;
• structural features of the main structure.

Before installation work The drawing must be completed. Based on the size of the building, it is determined required amount material.

Helpful information! When creating a carport, it is worth considering the passage of a loaded vehicle.

Preparatory work

Before the planned sheds attached to the house are created, photos of which can be viewed on the website, it is necessary to carry out preparatory work. For this purpose, a suitable area is marked out, and trees are uprooted from it. The clean area is leveled. At the same time, sand and gravel are added.

Recesses are drilled under the canopy supports. And at this stage it is worth considering laying the cable under the lighting sources. A certain step for placing supports is selected. It depends on the weight of the roof and frame part.

Racks are lowered into the prepared holes and poured concrete mixture. The pillars are set according to level.

Important information! If they are located close groundwater, then the ends of the pillars need to be additionally waterproofed. Metal supports pre-treated with a primer.

How to make a polycarbonate canopy attached to a house: photos and installation steps

12-15 days after the concrete has completely hardened, you can begin assembling the structure. Brackets are mounted on the wall, and then a transverse beam is mounted on top.

Creating a sheathing

Performed top harness. The end parts of the racks are connected using a transverse beam and to each other. In this case, parallel laid profiles are used. The metal frame system is welded together, and the wooden frame system is tightened with steel corners.

Welding areas are cleaned, primed and painted. The rafters are mounted with transverse parts in increments of 600 mm. TO load-bearing beam The structure is secured using steel angles. The sheathing is laid across the rafters and mounted with self-tapping screws.

Roof installation

Sheets of roofing material are cut to size. Then they are attached to the sheathing. Holes for self-tapping screws are first made in the polycarbonate.

To facilitate water drainage, the cells should be directed downwards. When working with plastic, do not forget to leave gaps between. The dimensions of the holes should be made with a margin of 2-3 mm. There are some features of installing roofs made of other materials.

Wood beams can be used as beams. Over time, cracks may appear in the material, which will reduce the rigidity of the structure. After installing the beams, transverse boards are installed, and then the metal tiles are fastened. Installation of this material is carried out from the bottom sheets. It is worth considering that there should be an overlap of the upper sheets on the lower ones.

Sheds with a metal frame can be found both in the courtyards of private houses and in in public places. These are covered parking lots for cars, canopies for porches and balconies, shelters for grills, barbecues, woodsheds and much more.

In this article we will tell you why structures of this type are so popular and where they are most often used. You will also learn how to calculate and build a metal canopy with your own hands.

Metal canopies with polycarbonate coating

The smaller the future building, the easier it is to calculate it. The exception is shelters with an area of ​​15 m2 or more - here it is better to entrust the project of a canopy made of metal structures to professionals.

Advantages of metal canopies

It is no coincidence that metal is so popular as a material for the manufacture of polycarbonate canopy frames. Its most important advantage is durability. With proper installation and maintenance during operation, such a building can last for several decades. All care involves treatment with anti-corrosion compounds or paints containing them. If rust stains occur, it is enough to spot clean the affected areas and treat them with special preparations.

Also worth noting wide choose metal profiles: different thicknesses walls, geometry and cross-sectional diameter. Pipes also vary in metal thickness and diameter. Thanks to this, you can always choose the item that corresponds to the purpose and dimensions of the future building. For example, for a small steel canopy over the porch you will need a profile, rectangular in cross-section, with a diameter of 15 mm and a wall thickness of 1 mm; the supports of the car parking shelter are erected from pipes or profiles with a diameter of 40 - 50 mm, with a wall thickness of 2 mm, etc.

Note:we must not forget about aesthetic side question. Metal allows you to build beautiful forged canopies. Even though they cannot be made without special equipment and skills, shelters of this type are usually ordered from workshops specializing in artistic forging.

Types of materials

Canopies are made from stainless steel, as mentioned above, from a metal profile, a metal pipe and from forged metal. The first option is the most common, since it is presented in a wide range in stores. In addition, square and rectangular profiles can be equally conveniently mounted either with self-tapping screws or by welding. For small parts or small sheds, a corner of different sizes works well.

How to make a metal canopy with your own hands: the video describes how to assemble a canopy from a steel pipe.

Less commonly, metal canopies made of pipes. In principle, the range of them in stores is also wide, both in diameter and in wall thickness. But in installation they are a little more complicated, it is more difficult to create right angles with them. Although there are also advantages - it’s not difficult to buy old heating pipes from which you can assemble a budget building. For example, you can make a canopy from a profile pipe with your own hands for firewood or a country shower. Forged metal is mentioned above.

Different types of profile pipes

What type of canopies are made of metal?

Such shelters can be used for different purposes. For example, very often do-it-yourself carports are made from metal. This could be either a small roof over a single parking lot or a swimming pool, or huge shelter with an area of ​​more than 30 m2. Any differences will be in the design and technical specifications the material used.

It is very good to make metal canopies over a porch or balcony from a thin profile or forging. In the first case, we get a durable, visually lightweight frame that is easy to assemble with your own hands. Forging is either just a beautiful, openwork canopy, or a whole work of art, made according to individual project. True, a forged frame will cost much more than a profile one.

For your information: Sheds over wood sheds are also erected from metal, although less frequently. Here, support posts and a roof frame are usually made, and the walls are covered with wood - these are the features of storing firewood. For these purposes, dismantled pipes are usually used heating system or profile waste from other construction. New materials for woodshedders are purchased only in cases where the canopy also has a decorative function, being located directly next to the grill or barbecue oven.

How to calculate a metal canopy

• We draw a sketch with approximate dimensions and marks regarding the type of profile used.
• We accurately measure the installation location and, based on the obtained figures, create a drawing of a canopy from a profile pipe.
• We decide what cross-section the metal profiles or pipes of the trusses and lathing will be.
• We enter new data into the drawing and use it to calculate the amount of required materials. At this stage it will become clear how much and what kind of hardware will be required.

We do not take into account the parameters of roofing materials, since the roof area will be small. When calculating a truss made from a profile pipe for a canopy, do not forget to include required quantity diagonal gratings. If it is a forged metal structure, then we only make a sketch of it with the desired dimensions. The master will do the rest for you.

Drawing of a forged visor

Large buildings like carports or adjoining galleries require more careful attention. In addition to performing the above steps, here you need to correctly determine the shape of the roof frame from the profile. The most common option is arched design. It will resist snow and wind loads well, and installation will not cause any special problems.

Note:in an area with strong winds better to give preference gable roofs. The slopes of the frame will be oriented to the ground at a large angle, which means there is less risk of damage to them by the wind. In addition, rain will be less likely to seep into the building.

Self-construction of a metal polycarbonate canopy over the recreation area

Installing a canopy for a house made of metal profiles with your own hands will require some physical effort, but you can handle it quite quickly. The most important thing is to approach the matter responsibly.

Pouring the foundation and installing load-bearing supports

The foundation for canopies made of metal profiles is made columnar. The holes are dug with a manual or mechanical drill to a depth of 50 cm. No reinforcement is made, the solution is mixed from 3 parts sand and 1 part cement. It will take three days for the foundation to harden, after which further work can begin.

“Heels” are welded to the bottom of the support pillars - mortgages, due to which the entire structure will be attached to the foundation. We drill holes in the corners of the mortgages and fasten the pillars with anchors to the concrete. We carry out this work by checking the building level.

Canopy roof assembly

The answer to the question - how to weld a truss for a canopy is quite simple. This is made from side profiles and diagonal grilles. Usually the former have a cross-section 10 mm larger than the latter, but it can be the same. We start by splicing along the edges, then continuing to move towards the center:

• Spot baiting.
• Check the level and, if necessary, straighten with a sledgehammer.
• Complete welding of elements.

Usually the side and rafter trusses are assembled separately, then they are installed on supports in turn: first the side ones, and the rafters on them. However, if lifting equipment is available, the entire roof frame can be assembled on the ground, as shown in the photo below.

Building a metal canopy: photo of the assembled roof frame

We lift the trusses or the finished frame from the profile onto the supports - here you will need at least two pairs of working hands. Next are the standard steps: spot welding, level check, and then constant welding. After the entire frame structure has been assembled, we clean the welding areas from scale and treat them with an anti-corrosion compound. If the metal profile does not have protective coating over the entire surface - apply it yourself. This stage should be treated very carefully, since the duration of operation of the canopy depends on it.

Installation of polycarbonate

Polycarbonate sheets are laid on the frame as is, without removal protective film. Using a drill, holes are drilled on them for the fasteners to fit in - 4 cm from the edge. We do not use ordinary hardware for metal, but special thermal washers with O-rings and plugs. We put a thermal washer on the hole, tighten it with a self-tapping screw and close its cap with a plug. The insertion of the fastener must be strictly perpendicular to the surface of the polycarbonate. We twist it tightly, but do not overtighten, to avoid damage to the surface of the material.

The figure shows how to attach polycarbonate to the metal frame of the canopy: we use special thermal washers

We join polycarbonate sheets using a split profile. Its lower part is screwed onto the frame sheathing before the roofing material is laid. The cover is “fastened” using a toothed lock, the “legs” of which are located on both parts of the profile. The figure shows that the cover is equipped with rubber gaskets that provide additional insulation of the joints.

Split profile

And it remains last step– close the side cuts polycarbonate sheets with punched paper tape and then with an end profile. This way we will protect the roof air ducts from the penetration of moisture and pollution. This is the construction metal canopy finished, you can move on to finishing the area underneath.

Finishing the edge with an end profile

• Canopies are classified as the most simple structures, which are being built on a suburban or summer cottage. They are used for the most different goals: as a parking lot, storage area and many other options.

  Structurally, the canopy is extremely simple. This

  • frame, the main element of which is trusses for canopies, which are responsible for the stability and strength of the structure;
  • coating. It is made of slate, polycarbonate, glass or corrugated sheet;
  • additional elements. As a rule, these are decoration elements that are located inside the structure.

  The design is quite simple, and it also weighs little, so you can assemble it with your own hands right on the site.

  However, in order to get a practical, correct canopy, you first need to ensure its strength and long-term operation. To do this, you should know how to calculate a truss for a canopy, make it yourself and weld it or buy ready-made ones.

  Metal trusses for canopies

  

  This design consists of two belts. The upper and lower chords are connected through braces and vertical racks. It is able to withstand significant loads. One such product, weighing from 50–100 kg, can replace metal beams three times larger in weight. With proper calculation, the metal truss in, channels or does not deform or bend when exposed to loads.

  A metal frame experiences several loads at the same time, which is why it is so important to know how to calculate a metal truss in order to accurately find the equilibrium points. This is the only way the structure can withstand even very high impacts.

  How to choose material and cook them correctly

  

  Creation and self installation canopies are possible with small dimensions of the structure. Trusses for canopies, depending on the configuration of the belts, can be made of profiles or steel angles. For relatively small structures It is recommended to choose profile pipes.

  Such a solution has a number of advantages:

  • Load bearing capacity profile pipe is directly related to its thickness. Most often, to assemble the frame, a material with a square cross-section of 30-50x30-50 mm is used, and for small structures, pipes of a smaller cross-section are suitable.
  • For metal pipes They are characterized by greater strength and yet they weigh much less than a solid metal bar.
  • Pipes are bent - a quality necessary when creating curved structures, for example, arched or domed.
  • The price of trusses for sheds is relatively small, so buying them will not be difficult.

  On a note

  The metal frame will last much longer if it is protected from corrosion: treated with a primer and painted.

  • On such metal carcass You can conveniently and quite simply lay almost any sheathing and roofing.

  Methods for connecting profiles

  How to weld a canopy

  Among the main advantages of profile pipes, the non-shaped connection should be noted. Thanks to this technology, a truss for spans not exceeding 30 meters is structurally simple and relatively inexpensive. If its upper belt is sufficiently rigid, then the roofing material can be supported directly on it.

  The formless welded joint has a number of advantages:

  • The weight of the product is significantly reduced. For comparison, we note that riveted structures weigh 20%, and bolted structures weigh 25% more.
  • Reduces labor and manufacturing costs.
  • welding cost is low. Moreover, the process can be automated if you use devices that allow uninterrupted feeding of welded wire.
  • the resulting seam and the attached parts are equally strong.

  One of the disadvantages is the need to have experience in welding.

  Bolt-on mounting

  Bolted connections of profile pipes are not used very rarely. It is mainly used for collapsible structures.

  The main advantages of this type of connection include:

  • Simple assembly;
  • No need for additional equipment;
  • Possible dismantling.

  But at the same time:

  • The weight of the product increases.
  • Additional fasteners will be required.
  • Bolted connections less durable and reliable than welded ones.

  

  How to calculate a metal truss for a canopy made from a profile pipe

  

  The structures being erected must be rigid and strong enough to withstand various loads, therefore, before installing them, it is necessary to calculate a truss from a profile pipe for a canopy and draw up a drawing.

  When calculating, as a rule, they resort to the help of specialized programs taking into account the requirements of SNiP (“Loads, impacts”, “ Steel structures"). You can calculate a metal truss online using the metal profile canopy calculator. If you have the appropriate engineering knowledge, you can carry out the calculation yourself.

  On a note

  If the main design parameters are known, you can look for a suitable finished project, among those posted on the Internet.

  

  Design work is carried out on the basis of the following initial:

  • Drawing. The configuration of the frame belts depends on the type of roof: single or gable, hip or arched. The most simple solution can be considered a single-pitched truss made from a profile pipe.
  • Design dimensions. Than with big step trusses will be installed, the greater the load they can withstand. The angle of inclination is also important: the greater it is, the easier it will be to remove snow from the roof. For the calculation, you will need data on the extreme points of the slope and their distance from each other.
  • Dimensions of roofing material elements. They play a crucial role in determining the pitch of the trusses for a canopy, say. By the way, this is the most popular coating for structures built on own plots. They bend easily, so they are suitable for constructing curved coverings, for example, arched ones. All that matters is how to do it right calculate a polycarbonate canopy.

  The calculation of a metal truss from a profile pipe for a canopy is performed in a certain sequence:

  • determine the span corresponding to the technical specifications;
  • to calculate the height of the structure, substitute the span dimensions according to the presented drawing;
  • set the slope. According to the optimal shape of the roof of the structure, the contours of the belts are determined.

  On a note

  The maximum possible pitch of trusses for a canopy when using a profile pipe is 175 cm.

  How to make a polycarbonate truss

  

  The first stage of making trusses from a profile pipe for a canopy with your own hands is to draw up a detailed plan, which should indicate exact dimensions each element. In addition, it is advisable to prepare an additional drawing of structurally complex parts.

  As you can see, before you make trusses yourself, you need to be well prepared. Let us note once again that while the choice of product shape is guided by aesthetic considerations, a calculation path is required to determine the structural type and number of constituent elements. When testing for strength metal structure It is also necessary to take into account data on atmospheric loads in a given region.

  The arc is considered an extremely simplified variation of the truss. This is one profiled pipe with a round or square cross-section.

  Obviously, this is not only the simplest solution, it is also cheaper. However, polycarbonate canopy poles have certain disadvantages. In particular, this concerns their reliability.

  Let's analyze how the load is distributed in each of these options. The design of the truss ensures uniform distribution of the load, that is, the force acting on the supports will be directed, one might say, strictly downward. This means that the support pillars perfectly resist compression forces, that is, they can withstand the additional pressure of the snow cover.

  The arches do not have such rigidity and are not able to distribute the load. To compensate for this kind of impact, they begin to unbend. The result is a force placed on the supports at the top. If we take into account that it is applied to the center and directed horizontally, then the slightest error in calculating the base of the pillars will, at the very least, cause their irreversible deformation.

  An example of calculating a metal truss from a profile pipe

  The calculation of such a product assumes:

  • determination of the exact height (H) and length (L) of the metal structure. The latter value must exactly correspond to the span length, that is, the distance overlapping the structure. As for the height, it depends on the designed angle and contour features.

  In triangular metal structures, the height is 1/5 or ¼ of the length, for other types with straight belts, for example, parallel or polygonal - 1/8.

  • The angle of the grid braces ranges from 35–50°. On average it is 45°.
  • It is important to determine the optimal distance from one node to another. Usually the required gap coincides with the width of the panel. For structures with a span length of more than 30 m, it is necessary to additionally calculate the construction lift. In the process of solving the problem, you can obtain the exact load on the metal structure and select correct parameters profile pipes.

  

  As an example, consider the calculation of trusses for a standard 4x6 m lean-to structure.

  The design uses a 3 by 3 cm profile, the walls of which are 1.2 mm thick.

  The lower belt of the product has a length of 3.1 m, and the upper one – 3.90 m. Between them, vertical posts made of the same profile pipe are installed. The largest of them has a height of 0.60 m. The rest are cut out in descending order. You can limit yourself to three racks, placing them from the beginning of the high slope.

  

  The areas that are formed in this case are strengthened by installing diagonal lintels. The latter are made of a thinner profile. For example, a pipe with a cross section of 20 by 20 mm is suitable for these purposes. At the point where the belts meet, stands are not needed. On one product you can limit yourself to seven braces.

  Five similar structures are used per 6 m length of the canopy. They are laid in increments of 1.5 m, connected by additional transverse jumpers made from a profile with a section of 20 by 20 mm. They are fixed to the upper chord, arranged in increments of 0.5 m. The polycarbonate panels are attached directly to these jumpers.

  Calculation of an arched truss

  

  The manufacture of arched trusses also requires precise calculations. This is due to the fact that the load placed on them will be distributed evenly only if the created arc-shaped elements have ideal geometry, that is, the correct shape.
