Today, most private houses are built on two or more floors. On this basis, the question arises about the need to move around the house, or rather, build a staircase. For such a structure you can use various materials both traditional and exclusive. But many owners country houses in order to save money, they are interested in how to build a staircase with their own hands.

Types of wooden stairs

The first thing to consider when developing a project drawing is this is the size of the staircase landing. Also, when choosing a design, you need to take into account the cost of materials, the ease of use of the structure (during descent and ascent), especially if it is installed for daily use. It is also necessary to pay attention to the aesthetics of this structure, since it must fit into the style and interior of the rooms. Wooden stairs are divided into two types - marching and spiral. In order to choose for yourself which one is better to install, you need to understand the pros and cons of each of them.

Screw designs have quite complex shape, but their main advantage is that they take up minimal space, which is especially important in small house. It should be noted that such stairs are installed quite rarely when compared with marching ones. This is due to the fact that they are difficult to install and operate. Especially if you are lifting large equipment.

Nevertheless, such designs have many fans. Spiral staircases can become a real elegant element of the interior. Plus it's compact.

When installing screw structures, you need to make accurate calculations, since making a small mistake during installation can subsequently lead to many injuries.

Marching structures

Such structures are more stable and durable than screw ones. Although screw structures also take up much less space, than marching ones, they are installed less often.

Mostly in private houses, structures with one or two flights are installed. But in principle there could be more. They also have a lot variety of options designs.

To save space, marching structures are installed on two flights, and the second part can be rotated to the first from 90 to 180 degrees. When planning the main objective- this is a creation comfortable conditions use of such a design.

Sometimes, for convenience, curved marching stairs. Smooth turning is ensured by installing corner steps. Such steps can also be installed on two-flight structures instead of a platform between them.

Single-flight wooden

Single-flight design- the most popular option among owners of private houses and not only. The staircase can be located either in the middle of the room or near the wall.

The area under the single-flight structure is also put to good use. For example, if you install a partition and put small door, it will be functional utility room for storing things and tools.

It should also be noted that the advantage is the greater strength of such structures, since they have additional support in the form of walls.

Rotary step design

A single-flight staircase with rotating lower steps is usually installed to highlight the interior or due to the specific layout of the room. For example, if there is a window installed on the wall near the future staircase and you don’t want to cover it with a two-flight structure.

At the right approach not only to the structure, but also to the interior of the room, turning steps will add elegance to the room. At the same time, their functionality is not lost at all.

Two-flight simple

A staircase that has two flights and a turning platform between them, is often used when there is a need to install such a structure above front door, thereby significantly saving space. Moreover, it is very compact, and a closet for storing things under it can also be made.

Wood is rightfully considered the most popular material for building such structures. Before you begin installation work wooden stairs, you need to think through some possible nuances. First of all, you need to decide on the type of structure.

Eg, spiral staircase takes up much less space. But the downside is the complexity of producing and installing such a staircase. Moreover, it is very inconvenient to move along such stairs, since they are quite narrow and it is difficult for a “large” person to climb and descend along them. And there can be no talk about transferring any equipment at all.

One of the most popular types of stairs in private households is the flight of stairs. Making a wooden staircase with your own hands is not difficult. They are very comfortable and spacious. Structures of this type come with one or two spans, but there is no fundamental difference in the construction technique.

There are also a few things to consider:

• How much space in the house is the owner willing to allocate for installation.
• What is the distance between floors?
• What kind of load does it have to withstand every day?
• What elements will the structure have, its height, width, length, etc.

After determining the shape and type of structure, it is necessary to prepare all materials for work. In order not to overpay for extra purchased material, you need to carefully consider the design and make an accurate drawing.

Don't forget about the clearance above the stairs. When a person of average height walks along it, he should not bend down or hit his head on the ceiling.

Having measured all design parameters and made drawings, you can proceed to the purchase and preparation of all necessary materials. For such structures you can use wood different breeds. Craftsmen generally recommend using oak, beech or larch. But these types of wood are very expensive. A more economical option - coniferous trees. Moreover, they also have sufficient strength for such work and are easy to process.

When purchasing basic material, you must pay attention to its quality. There should be no rotten parts, fallen knots, cracks or various deformations. The wood must also be well dried. Knots on the tree are allowed, but not in large quantities. Such a tree is considered second-class. Furniture cannot be made from it and it is better to recycle it.

For installation you need:

In addition to the materials, you must first prepare the necessary tools:

• Measuring tools (tape tape, corner, construction ruler).
• Drill for making holes (you can use a battery-powered one).
• Hacksaw for wood and metal. Alternatively, you can use an electric saw and jigsaw.
• A set of screwdrivers or a screwdriver with different attachments.
• Chisel and hammer.
• Sandpaper.
• Plane.

A previously made drawing should always be near the construction site in order to be checked and not make mistakes.

The next step is to install a wooden staircase with your own hands. Step-by-step instructions are needed for correct and consistent assembly. When the drawing is in hand and all the materials and tools are ready, then work on assembling the structure can begin.

The following steps must be followed:

At this stage the assembly is complete. All that remains is to cover everything with a layer of varnish or paint. Before painting, you can apply a ball of antiseptic to protect against pests. If you want to make a staircase in wooden house, then this can also be done easily. The main thing is to follow the correctly prepared drawing, select quality materials And necessary tools. Next, put in a little effort - and you will have a chic, comfortable and required element interior at the disposal of its owner. A staircase will decorate your home and make life easier.

The material from which the stairs are made can be different - wood, iron, concrete or a combination of these materials. But most often, wood is used to build stairs.

Any structure must be safe for movement on it. To do this, before constructing the staircase, it is necessary to perform calculations based on what type of staircase construction is expected.

To calculate a wooden staircase, do the following:

1. Determine the height of the interfloor space, from floor to ceiling, taking into account interfloor covering, and determine the area that will be allocated for the stairs.
2. Determine the number of steps in the staircase based on their tread depth, riser height, and staircase inclination angle. Typically the height of the riser is 150 - 200 mm, and optimal width the approach is usually 250 - 320 mm.
3. You should also take into account the height of the clearance between horizontal plane steps and the lowest part ceiling structure, this is necessary so that a person, when going up or down the stairs, does not touch the ceiling structures with his head.

General examples of drawings for wooden stairs

Before making any dwg drawings, you need to select a stair type.

It is necessary to perform certain measurements and calculations, and determine the general parameters of the stairs:

1. The angle of rise of the stairs, this parameter is usually in the range of 23 - 37 degrees.
2. The minimum height between the ceiling and steps must be at least 2 m.
3. The width of the staircase itself must be at least 1 meter.

After determining all the parameters, you need to draw a floor plan, on which you need to mark the location of the staircase and all its dimensions in relation to the floor plan. Worth doing separately general drawing the entire staircase for better understanding all necessary parameters.

All drawings can be made manually, but in order to avoid mistakes, it is best to make all drawings online using a special calculator.

If a person finds it difficult to create a drawing of a staircase on his own, you can use ready-made drawings and diagrams of stairs, print them out, and select the most best option. But this must be done at the stage of building a house, since it will be difficult to select a drawing for a finished building.

Detailed and general description of online calculation of wooden stairs

To calculate all the necessary parameters for creating it yourself, you need to take all the dimensions, such as the height between the floors, the area that will be allocated for the staircase, the angle of its inclination, the length of the opening, the number of steps.

To calculate a wooden staircase, it is best to use special online calculators or special utilities:

1. Various utilities also allow you to calculate, view, including in 3D format, and, if necessary, edit everything and redo all diagrams and drawings. You can even create a diagram of the entire house in such utilities, as well as draw a staircase and see how everything will look on a virtual layout.
2. When, you need to decide on the type of staircase, it can be single-flight, double-flight, spiral, staircase with a 180-degree turntable, etc. and each type of staircase requires its own calculation.

That’s why you should use special online calculators or special utilities, which is much more profitable and easier even for novice builders.

Basic drawing for a wooden staircase

The main advantage of a wooden staircase is its relative lightness, environmental friendliness, besides, wood is easy to process, and a wooden staircase will look optimal in a country wooden house.

But, before making a staircase to the second floor of the house, you need to make a drawing of the staircase, which will take into account all the parameters:

1. Markings are made based on the drawings wooden blanks, from which the staircase will subsequently be assembled. All dimensions that will be on paper are transferred to the workpieces, and they are sawed according to the markings applied.
2. But, before making drawings and cutting up the material and then assembling the stairs, you should evaluate your strength, since not everyone can competently draw up a drawing and correctly cut all the material.

Before making a drawing, it is necessary to measure the place in the room where the staircase will be located. This is the height from floor to ceiling, the width of the floor, you should also take into account the type of staircase, its angle of inclination, fastening system, etc.

Without this data, making a drawing of the staircase, much less manufacturing it, will be almost impossible.

The principle of drawing a wooden staircase to the second floor

Houses are built two-story, three-story, and to move between floors, it is necessary to equip a staircase.

The manufacture of any staircase begins with determining its type, this can be:

• Spiral or spiral staircase, one-flight classical staircase, two-flight with a turn, etc.;
• Also, a staircase, in addition to its main function of ascending or descending, can be practically invisible in the room, or, on the contrary, it can stand out in the interior and even serve as a decorative decoration.

Therefore, before you start, you need to choose its type, after that you should schematically draw a house plan, the staircase itself and see how this or that type of staircase will look on the diagram. If the person is satisfied with everything, you can begin to create detailed drawings of the staircase.

When creating a drawing, you should take into account all previously made measurements, the angle of inclination, the width and height of the steps, the width of the staircase itself; if you plan to make a fence, then it should also be depicted in the drawing.

Schemes and drawings for making wooden stairs with your own hands

The staircase is required element houses, it provides a connection between floors, and the staircase must provide comfortable movement along it, be safe and fit into the interior of the room. Planning and building a staircase should be based on building codes, and accurate calculations and drawings are also necessary, since if this is not done, then later, during manufacturing, errors may be discovered.

Nuances that will prevent reworking the entire structure, unnecessary consumption of materials and time:

1. Before creating drawings, you need to decide on the type of staircase, look different examples, and choose the one that will most fully satisfy all the requirements. After this, you can begin to create drawings and plan the arrangement of stairs in one place or another of the house.
2. Before creating a drawing, you should first take a measurement; this is the height from floor to ceiling, taking into account the interfloor partition. And also calculate the number of steps, their width, height and angle of inclination of the stairs, etc.
3. The drawing should not only show all the dimensions of the staircase, but also indicate the railings and their height.

It's also worth drawing general scheme home, which will display the location of the stairs indicating the occupied area.

Such a diagram will allow you to better understand what the finished staircase will look like and will allow you to double-check all calculations before manufacturing the staircase.

For a novice builder, based on the drawings, it is best to start making the most simple stairs using a load-bearing beam - stringer. Their number in the staircase can vary from 1 to 3.

DIY wooden staircase: calculations (video)

When building a multi-storey building, it is necessary to arrange stairs so that you can get from floor to floor comfortably and safely for the health of residents.

The most popular staircase system is the flight design. The technique of constructing it with your own hands is the simplest and most accessible. A flight of straight stairs can be made even by a beginner in a relatively short period.

We’ll talk about how to do this correctly and efficiently in this article, illustrated with a large number of high-quality photos and video instructions.

March of stairs - design features

A straight staircase is easy to manufacture and is considered a good option for private country houses and summer cottages. When building such a system with your own hands, you need to remember two important requirements - convenience and safety.

The construction technique of such a structure should be based on existing norms and standards.

Basic elements of a march

For a clearer understanding of how to make a straight staircase, you need to know its main components. The flight of stairs includes the following elements:

• load-bearing beams - these can be bowstrings or stringers;
• support pillars– hold the entire structure;
• steps - consist of a tread and a riser;
• fencing - includes balusters, handrails (railings) and decorative elements.

Stringers

Stringers are the main component of a flight of stairs, representing a load-bearing deck that holds the entire system.

Stringers can be made from wood, metal profile or reinforced concrete.

The flight of stairs may have:

• one stringer - load-bearing beam goes along the center of the structure and steps are attached to it (see photo);
• two stringers - beams run along the sides of the march, as shown in the photo;
• three stringers - two elements on the sides, one in the center.

Bowstring

The flight of stairs can also be made on a bowstring, which in its function performs the same role as a stringer.

In the stair stringer, cutouts for steps are made with inside beams

steps

A step consists of two elements - a tread and a riser.

Tread is a horizontal surface, 30 cm wide and about 90-150 cm long. The length of the tread is determined by the width of the tread itself. flight of stairs.

The riser is the vertical part of the step, 15-20 cm wide.

Fencing

The fence must be installed on a flight consisting of more than three steps. A row of balusters is called a balustrade. Balusters determine the style of the entire system. The railings are fixed to the fence. The main requirement for them is a smooth surface, since a person rests on them when moving up the stairs.

Requirements for the flight of stairs

The technique of erecting a marching structure with your own hands requires compliance with the following established GOSTs and generally accepted requirements:

• The width of the march ranges from 80 cm to 1 meter.
• The height of the fence is at least 90 cm.
• The weight that the march must withstand is from 180 to 220 kg.
• The load that the fence must withstand is at least 100 kg.
• The angle of inclination of the stairs is no steeper than 38 degrees.

DIY technique for constructing a flight of stairs

Before you begin installing a flight of stairs with your own hands, you need to outline the stages of the upcoming work. Manufacturing a staircase system consists of the following steps:

• Choice of manufacturing material.
• March design and calculation.
• Production of stringers.
• Installation of steps.
• Installation of fencing.
• Finishing work.

Choice of material

At the beginning production process you need to decide what material the stairs will be made from. But, since we're talking about about the march for a private home, then the best material Natural wood is used to make the staircase structure.

As for the species, on the advice of experts, it is better to choose pine wood. To build a flight of stairs we will need:

• beams for stringers;
• support pillars;
• edged boards for steps and risers;
• ready-made balusters and railings.

The best material for building a staircase with your own hands is pine.

March design and calculation

Before execution practical work It is important to correctly calculate the future design.

First you need to design the following basic elements - stringers, steps, risers and fencing.

Steps are calculated using the formula:

2A+B=64 cm, where

• A – width of the component;
• B – step height (usually 14-17 cm).

March design - responsible and necessary stage

• First, let's measure the height of the stairs.
• Let's determine the number of steps of a flight of stairs - for this we divide the height of the stairs by the value B. If the height of the structure is 240 cm and the height of the step is 16 cm, then the number of steps will be 15 (240/16).
• Calculation of the width of the steps - parameter A. Understanding the number of steps (B), this is not difficult to do: 2A+15=64, 2A=49, A=49/2=24.5 cm.

Production of stringers

For stringers, a pine beam with a thickness of 40 mm and a wood moisture content of no more than 13% is suitable.

The sequence of stringer production is as follows:

• Prepare a pattern that follows the curves of the steps.
• Apply markings to the blank using a template.
• Use a hacksaw to cut out the teeth.
• The resulting blank can be used as a template for cutting out the second stringer.
• Install the stringers in the place where the march will be placed, making sure that the ends of the parts rest against the floor of the first and second floor.

Installation of steps

The steps can be fixed to the stringers using special wooden parts (fillies) or directly. Before installing the steps, you need to prepare the required number of risers and treads, taking into account the significance of the protrusions.

The first step is to install the risers. For this purpose, screws or nails are used. The fillies are fixed with dowels. Next, the steps are installed.

Fencing installation

When all the steps are installed, you can begin installing balusters and railings. Screws and studs are used to secure them.

Finishing work

The final stage of constructing a flight of stairs with your own hands is to varnish the stairs. This procedure will protect the system from harmful insects, mold and dampness.

Let's consider such a simple and unpretentious thing that is found in every home like an attached wooden staircase. Many people make it themselves, and almost everyone has encountered a situation where it failed.

Most makeshift stairs are unsafe. It’s good if the crossbar comes off and your foot slips onto the next one below. But in many cases, falling from a height can cause serious injury. To prevent this from happening, let's look at how to properly make a ladder with your own hands from wood.

What are the parts of the stairs called?

To make it easier to cover the topic, we will present the generally accepted terms that denote its details.

There are only two of them:

1. the rungs on which we step or grab with our hands are called steps;
2. the long bars to which the steps are attached are bowstrings.

Attention. It is more correct to climb the stairs holding your hands not on the steps, but on the bowstrings. Although a ladder is used by one person, many fire escapes have the same design. When in emergency situation If several people move along the stairs one after another, then the one who holds on to the bowstrings does not risk falling, because his hands will be crushed by the one above.

Why are most stairs done wrong?

Almost every wooden staircase is constructed as follows:

• Find bars and slats or even poles of a suitable cross-section.
• Cut the material to size.
• Everything is knocked together with nails.

The worst option is shown in the photo above; usually everything looks more beautiful. This is a dangerous and wrong approach. The nail holding the step in place can break down from time and corrosion, or be forced through the wood, causing the joint to fail.

Fastening with several nails or using screws or through bolts with nuts does not save the situation. Also, if the section is chosen incorrectly, or the material is defective, then the step or string, especially on a long staircase, may break.

Requirements for stairs

Wooden stairs used in production must comply with regulations.

Here are the names of several of them:

• SNiP 12 – 03 – 2001: Occupational safety in construction.
• POT RM-012-2000: Rules for labor protection when working at height.
• GOST 24258 – 88: Specifications for scaffolding means.

Let’s not invent anything new; we’ll apply them to ours as well. home construction. Our wooden extension ladder, drawings and materials for it, and assembly method will fully comply with them. Let's list the main requirements.

Material requirements

• Steps and strings of stairs must support a weight of at least 120 kg.
• Elements of stairs are made from pine, as a last resort, the steps can be made of hardwood (birch, beech, ash, oak).
• Fiber inclination of more than 7% is not allowed.
• The wood must not have any defects violating its strength characteristics - cracks, knots sawn along the axis, curls, resin pockets. Bowstrings should not have core tubes.

• Staircase elements are made from solid pieces of wood. As an exception, manufacturing from strips glued along the entire length is allowed. At the same time, the laminated veneer lumber should not be inferior in strength to solid wood, and should not have delaminations and swelling at the joints.

• External surfaces must be sanded and not have any irregularities or burrs.

Design requirements

1. Wooden stairs are not made longer than 5 meters.
2. On the upper outer edge of the steps rectangular section a chamfer of at least 2 mm must be removed.
3. The strings must be tied before the first and after the last step, as well as every 2 meters in length, with steel ties with a diameter of at least 2 mm on nuts and washers.
4. The minimum cross-section of steps is 2x4 centimeters.
5. The step pitch is no more than 0.35 meters.
6. The steps and strings are assembled into a tenon. It is allowed to connect with metal fasteners, with the steps deepening into the grooves selected in the staircase array. When assembling into a tenon, glue that is resistant to moisture is used.

Safety requirements

1. There should be no protruding wooden or metal elements; all parts are buried flush.
2. If the ladder rests on the ground, then a frame with metal spikes is installed at the bottom of the strings to prevent slipping. For the same purpose, to work on hard surfaces(concrete, parquet, ceramic tile) rubber shoes or pads are installed at the bottom.
3. When supporting the upper part of the ladder on pipes or similar parts, metal hooks are installed at the top to ensure reliable fixation and prevent tipping.

If you meet all these requirements, then your ladder will be reliable - but be sure to also carry out a test (we will talk about the method below). But if you have the desire and ability, you can additionally carry out a design calculation.

Calculation of staircase strength

We will try to make our calculation instructions understandable even to people without technical education who are not familiar with the basics of strength of materials and theoretical mechanics. We present the terms, but this is so that it is clear to specialists (or so that they do not swear). Simply, take your measurements for calculation. We perform the following steps.

Preparing the initial data

1. We determine what our wooden extension ladder will look like with our own hands; it is not necessary to make drawings; sketches (sketches or, as engineers call them, “kroki”), which will have all the dimensions, are enough. We get a section of steps of 3.5x5 cm, length 50 cm. Section of strings 4x9 cm, length 240 cm.

1. For pine at a humidity of 15% (average value under normal operating conditions), the tensile strength is taken to be 100.8 kgf/cm2 (10.08 MPa). If other breeds will be used, this value can be found in reference books or on the Internet.
2. The modulus of elasticity of pine wood is 100,000 kg/cm2.
3. We accept the load that we will apply during testing and that is required by the standards ( average person much lighter) - 120 kg.

Calculating the steps

1. We calculate the gross moment of resistance; for this we multiply the width of the section of the step by the square of its height and divide by six: 3.5x5 2 /6 = 14.58 cm 3.
2. We calculate the maximum bending moment. To do this, divide the static load (weight) by eight and multiply the resulting number by the difference between the double length of the step (50 cm) and the subtracted length of the section on which the load is applied (this section is equal to the width of a person’s sole 10 cm): x(2x50-10)=1350 kg x cm
3. We determine the design bending stress by dividing the maximum bending moment by the gross moment of resistance: 1350/14.58=92.59 kgf/cm2.

The resulting value is 92.59 kgf/cm2, less than the tensile strength of pine wood 100.8 kgf/cm2, which means the step will withstand.

Calculating the bowstrings

For bowstrings, the load is applied pointwise, at the place where the step is attached, and we also take only half the weight of 60 kg (two strings).

1. We calculate the gross moment of resistance: 4 * 9 2 /6 = 54 cm3.
2. We calculate the maximum bending moment: = 3600 kgf x cm.
3. We determine the design bending stress: 36000/54 = 66.67 kgf/cm2.

It also turned out to be less than 100.8 kgf/cm2, which means our bowstrings will not break. It is also advisable to additionally calculate the deflection; for steps it is insignificant in any case, but for bowstrings it is important.

1. To do this, we calculate the moment of inertia of the cross section. It is equal to the width of the section multiplied by the cube of the height and divided by 12: 4x9 3 /12 = 243 cm4.
2. According to SNiP, it should be greater than that determined by the formula: . In this formula: P - applied load (60 kg), L - length (240 cm), E - elastic modulus - 100,000 kg/cm2. We consider = 108 cm4.

243 cm4 is twice as large as 108 cm4, which means the deflection of our bowstrings complies with SNiP.

Making a staircase

After we have determined the requirements for safe stairs, determined its dimensions and even calculated it, you can begin manufacturing. We will need a minimum set of materials, the price for which is also low.

1. Beam for steps and strings.
2. Wire for ties or, better yet, long studs with ready-made threads.
3. Nuts and washers.
4. Rubber shoes, pieces of rubber or ready-made parts for forging the lower part with spikes. If hooks are needed on top, then so are they.
5. Screws.
6. Glue for assembly.
7. Drying oil and paint.

You can also get by with a minimal set of tools, especially if we already have timber the required section, but it’s more convenient if it’s nearby a circular saw And planer. We need:

1. Equipment for marking - pencil, ruler, tape measure, square.
2. Hacksaws for wood and metal.
3. Plane.
4. Mallet or rubber mallet.
5. Chisels and chisels, or better yet milling machine for wood.
6. Drill.
7. Spanners.
8. Dies with a collar.
9. Sandpaper.
10. Brushes for applying glue, drying oil and paint.

Let us describe the manufacture of wooden ladder DIY operations:

1. We process the workpieces to the required section.
2. Using a plane or machine we make their surface smooth.
3. We mark the required length of the bars, and if our staircase narrows slightly at the top, take into account that the steps will be of different lengths.

1. We cut the material to size.
2. We mark holes (if assembled into a tenon) or niches (if assembled with notching) for the steps in the strings. At the same time, if we are going to install the steps into a tenon, then there are two options - cutting them into the bowstring over the entire cross-sectional area (easier and faster) or making a slightly smaller tenon (more labor-intensive).
3. If we plan to embed steps into a tenon not with the entire cross-sectional area, then we prepare tenons for them. This is the most labor-intensive and time-consuming process. It is necessary to remove material from the step bars strictly in accordance with the shape of the holes on the strings; the process becomes more complicated if the staircase has a variable width (tapers at the top). The easiest way to do the job is to use ready-made holes on the bowstrings as templates. Be especially careful with this operation; the tenon must fit into the hole without play.
4. We join the steps with strings. If we make a cut into a groove, then we install them in the grooves and fasten them with screws or nails. For reliability, we use two fasteners for each joint. Additionally, you can coat the joint with glue. If we assemble it into a tenon, then we immediately install the steps into one string (with glue, in addition you can also use a nail or screw, the main thing is that it does not split the material). Do not place blades, fabric or other material for a tight fit. If the tenon fits in with a gap, then we redo it. When the steps are glued into one string, we join them to the second string in the same way.
5. After joining the steps with the strings, we drill holes for the ties, and their diameter should match the diameter of the wire or pins. Having drilled them out, using a drill with a diameter equal to the size of the washer, external sides string, select a hole to recess the washer and nut. Its depth is equal to the sum of the thickness of the latter.
6. Cut the pins or wire to size for the ties. Using a die, cut a thread on the wire from both ends, turning it into a hairpin.
7. To prevent corrosion, we paint or varnish the studs. This must be done in advance, because this part of them will be hidden in solid wood. At the same time, we do not touch the thread.
8. We install the ties in place. We place a washer under each nut. We tighten, controlling the force, so as not to push through the wood and not to create excess pressure on the steps (the main task of the ties is to prevent spontaneous spreading of the bowstrings).
9. Using a hacksaw, remove the protruding parts of the studs. We carry out the same operation with the ends of the steps. Additionally (not metal, of course) the joints can be processed with a plane.
10. We install rubber shoes or pads, spikes and, if necessary, hooks. We fasten them with screws.
11. We finalize the surfaces with a plane and sandpaper (if possible with a sander), you can use a scraper.
12. We cover the surfaces with varnish or paint; the wood can simply be varnished.

Our ladder is ready, but in order to be sure of its reliability, you need to test it.

In production, this operation is carried out with each staircase after production and every six months (it’s not a bad idea to do this at home), especially since the operation is not complicated.

1. The ladder is installed at an angle of 75 degrees (plus or minus five), this is its working position.
2. In the middle of one of the steps of the middle part, a static load of 120 kg is applied (a load is hung). Moreover, it should be suspended through a rigid pad covering 10 centimeters of the width of the step (simulating the load from the foot).
3. Inspect the stairs.

If there is no loss of strength and no damage is visible, the ladder is considered to have passed the test.

Advice. In production, the test results are recorded in a special journal. It indicates the test date, inventory number, unit affiliation and the date of the next test. The record is certified by the signature of the responsible person. Please take this into account if you are responsible for the safety of your subordinates at work.

I hope in our article we have given a comprehensive answer to the question - how to make a wooden ladder with your own hands? A staircase made in accordance with our recommendations will be truly reliable and safe. Enjoy working on it.

If a private house has more than one floor, you cannot do without a staircase. But besides the fact that it must connect the floors, the staircase must also fit into the interior. Therefore, when choosing a design, you need to pay attention not only to the dimensions and how much space it takes up in the room, but also to take into account the style. Then a hand-made staircase to the second floor will not only be a functional item, but also an interior decoration. The work is difficult and responsible, but you can do it.

Types of stairs to the second floor in a private house

All these structures can be made of metal, wood, concrete, glass, marble and others decorative stones, and often use combinations of these materials. But most often, the staircase to the second floor is made from wood, a little less often - from metal or combinations of metal and wood.

In addition, there are two types of degrees - open and closed. IN open stairs There is only a horizontally located part - the step itself; in closed ones there is also a vertical part - the riser.

Design standards

When designing a staircase, it is important to make it comfortable and safe. There are very specific numbers and recommendations that relate to the parameters of the steps and the general angle of elevation:

The number of steps is determined by simply dividing the height of the planned staircase by the selected riser height. For example, the height of the room is 285 cm. It was decided to make the elevation angle 40°. From the table we see that the height of the riser is 19 cm. Divide 285 cm / 19 cm = 15 steps. If the number turns out to be even, we slightly adjust the size accordingly to get an odd number.

If one of the steps turns out to be several centimeters smaller, this height is “taken away” from the first step. All others, including the last one, should be the same.

When choosing the size of the steps, comfort can be checked. If the double height of the riser is added to the selected step width, the result should be from 60 ms to 64 cm. The second test option is that the sum of the lengths of the tread and riser is optimally equal to 45 cm, but deviations of 2 cm in both directions are acceptable.

All these parameters must be taken into account when designing a house. If the house has already been built, you have to proceed from what is there and adjust the dimensions to the existing dimensions.

Spiral staircase

As already mentioned, a spiral staircase in a private house takes up the least amount of space. But it has a serious drawback: it is uncomfortable to walk on, and it is almost impossible to lift anything bulky to the second floor. So they are not very popular, although they look good and fit well into any interior.

Calculation features

When designing a spiral staircase, it must be taken into account that in some positions there are other steps above your head. Therefore, it will not be possible to make small risers.

The next feature is that the steps are all unequal in width - narrower on one side, wider on the other. The narrow part is attached to the central support (post), the wide part is attached to the walls or balusters. The standard for the width of the tread is measured in the middle part, and the wide part should not be more than 40 cm.

The span width is from 50 cm to 100 cm. The entire structure is doubled - a square with a side of 100 cm to 200 cm is required.

Prefabricated column design

This type of spiral staircase is the easiest to make: a pipe is placed on which wooden elements- steps, intermediate cylinders, etc.

If we look in more detail, then except metal pipe(in this case with a diameter of 40 mm), steps and balusters (available in any design) there are turned wooden cylinders (segments) that set the distance from one step to another.

On the other hand, the distance between the steps is maintained using cuts on the balusters. The steps are attached to these grooves (with glue + fasteners).

Do-it-yourself installation of a staircase to the second floor begins with the installation of a pillar. A hole equal to the diameter of the pillar is made in the floor of the first floor and the ceiling of the second. We insert the pipe into the hole, put on the enlarged washer, and tighten the nut. Further assembly is simple: the corresponding elements are mounted on the rod, and in parallel with the installation of the step, a baluster is placed and secured. The dimensions of the steps for this spiral staircase with the given parameters are in the drawing.

The steps are cut from laminated boards or furniture board. You can use solid wood, but of furniture quality, that is, without any defects and dried, with a humidity of no more than 8-12%. Although laminated wood is considered more reliable: it will definitely not be damaged and will not crack when dried.

For an example of assembling such a design, see the video. It has a prefabricated pole, but you can also use a solid one, although assembling the steps will be inconvenient - you will have to climb the stairs every time.

The design of a metal spiral staircase is presented in the following video fragment. For those who are familiar with welding, this option will be easier.

With or without railings - the choice is yours. In the photo on the right, a wooden spiral staircase on a bent stringer is a difficult element to execute. Forged twisted staircases are a classic of the genre.

Marching staircase to the second floor

Marching stairs are the most popular. Firstly, they are convenient to use, and secondly, the technology for their construction has long been proven. There are few specific features of the calculation. It is important to decide on the number of marches. One section should have from 3 to 15 steps. The most convenient ones have 11-13 pieces. If according to calculations it turns out that there should be more steps, they are divided into several sections, between which platforms are made. The dimensions of the platforms are multiples of the step length (600-630 mm). Then the ascent and descent will not cause inconvenience.

Kinds

Stairs with landings take up quite a lot of space. If there is not enough space, turns are added. The most common option is to place the staircase at the corners of two adjacent walls. Also, to save space, you can make winder (turning) steps instead of a platform. Just one point: the section with winder steps is the most dangerous. If the family has small children or elderly people, it is better to make a playground.

As we have said before, flight stairs are made on stringers (beams with a sawtooth edge) and on terives (just an inclined beam). Attaching steps to string beams requires more time and skill. Usually, a “seat” is cut out for each step - a groove is selected in the board. For additional reliability, bars are also nailed from below or corners are installed. The option with corners is reliable, but quite controversial from an aesthetic point of view. If the entire staircase is made of wood, metal parts very “cutting” to the eye. Carefully processed bars look much more organic. However, if the boards for the steps are thick enough and the string is wide enough, you can do without additional fasteners. In this case, it is important that the steps do not bend, otherwise they may jump out of the grooves.

Assembling steps on stringers is simpler: you have two or three supports to which parts cut to size are attached. The main task is to correctly mark and cut the stringers.

Installation of a flight of stairs with step-by-step photos

Stringers are made from wide boards 75-80 mm thick and 350-400 mm wide. If there is no solid dry board, you can use glued ones. How to calculate the stringer is described in the form, but you can assemble the staircase to the second floor not only as a free-standing one.

An example of assembling a staircase on stringers against a wall is below. First, we attach the support pillars on which they will rest winder steps. We attach the upper stringers to these pillars.

Then we install the lower ones. We attach the stringer near the wall on top decorative board— it’s easier to clean and dirt is less visible than on the wall.

We attach the lower stringers - one to the post, the second to the finishing board

Intermediate stringers are installed in last resort. This makes it easier to connect all the elements.

The installation of steps begins. After they are cut, sanded and painted, everything is simple: put them in place, drill a hole for the screw, then tighten it.

The next step is attaching the balusters. In this case they are made from stainless pipe with wooden inserts. A hole is drilled under each baluster into which a tube is inserted and fixed with a pin or any other available method.
