How to make a modular staircase. Do-it-yourself modular staircase: pros and cons of the solution, design options. Preparing for work

Self-expression of the owners of private houses can manifest itself not only when implementing the external appearance of the home, but also when working out the details inside it. For some, stairs are just a way to move between floors. But often it is located in the most visible place, thereby becoming part of the interior. And since such an element takes up a lot of space, it attracts a lot of attention, so its appearance is important. Owners who want to put “a piece of themselves” into their home can use the instructions for making a modular staircase with their own hands, given below.

Modular staircase and its types

First, let's figure out what it looks like, what types exist. The staircase got its name due to the frequent use of identical elements - modules. They can be mounted not only in a straight line, but also at an angle, thereby saving space in the room.

All stairs are divided into several types, so before starting work you need to decide which one is suitable for your case:

marching Stairs allow you to climb in a straight line and have wide steps. Such stairs are less often used in suburban construction because they take up a lot of space.
can be dangerous and difficult for children to lower and lift, but they take up little space.
rotary The stairs have intermediate platforms, which provides a comfortable climb, and they also take up little space. This type is most often used in private homes. Their design provides for several marches and the presence of turning areas.

If we consider the design of modular stairs, then the presence of a stringer can be identified as the main element. It is on this that the steps will be attached. The stringer can be mounted directly or at an angle, because it consists of stacked parts. This allows you to make stairs of any design. The stringer is fixed on support modules, which allow you to achieve the necessary rigidity. There are two such modules in the design - lower and upper. The modular staircase design includes a support pipe. She is also responsible for rigidity. It is installed after 1-1.5 running meters. This element can be replaced by a wall made of brick or concrete, on which the steps will be fixed.

Modules for installing single-flight stairs are much simpler in design, it is easier to ensure their rigidity without putting a load on the load-bearing elements. But during assembly, the presence of solid stringers is not justified.

There are also three options for assembling modules. When choosing one, you need to consider their pros and cons to choose the right one for you.

Manufacturing

Installation "module to module". This assembly forms a chain stringer, which is secured with two plates and locking screws. Such stairs were “pioneers,” which indicates the imperfection of the design. Now let's look at their shortcomings. The pitch of the steps is fixed rigidly and cannot be adjusted. After installation, a curvature may be noticeable, which, unfortunately, cannot be eliminated even by tightening the locking screws. Such a staircase may not stand the test of time. The mounting plates used in its design may sag, which again is not in the best possible way will affect the appearance. But this ladder also has advantages. It is easy to assemble.

The main element of this type of staircase is an all-welded module. It consists of two pipes, the diameter of which allows them to be assembled so that one fits into the second without creating gaps. The pipe, which has a larger diameter, is cut along the longitudinal seam. A corrugated pipe is welded on both sides of the cut rectangular shape, which is cut lengthwise. The halves of the professional pipes are tightened with bolts. A flange is welded to the upper part of the smaller diameter pipe. Holes are made on it for fastening the steps. Both modules - upper and lower - provide platforms for anchoring to the ceiling and wall.

Assembly should begin by securing it to the floor. This is done using the anchors of the lower module. Next, the remaining structural elements are mounted, ending with the fixation of the upper module using anchors. The rigidity of the staircase modules is ensured by tightening the bolts. The steps are attached to the flanges using screws or countersunk bolts.

Don't forget about installing fencing. After all, this is your safety. A thread is cut on the pipe. Its diameter should be 1/2 - 3/4 inches. On the step you need to make a hole of the same diameter. Next, a lock nut is driven onto the baluster thread, passing it through the prepared hole in the step and securing it with a lock nut.

Another type of assembly is using threaded rods. This eliminates the curvature of the stringer. But it appears new disadvantage, which manifests itself in the complexity of assembly; also, after installation, it is impossible to adjust the height of the step. When using this assembly, you need to be prepared for the fact that the threaded connections may become loose. This problem can be solved by tightening them, but you will have to repeat this procedure often during active use of the stairs.

This type of assembly uses two carved pipes having the same diameter. They are connected using a pipe of reduced diameter, clamping it with bolts inside the modules. There is a flange on it for fastening the step. With this design, it is possible to adjust the height of the step. As assembly instructions, you can use the instructions for the previous type of modular staircase. They differ in that with this type of construction, the lower and upper elements are first secured, and then they are connected.

The last type of assembly is fastening using the clamp principle. This design has a large number of modifications. It is the most perfect compared to the previous ones. The advantages of this type include maintaining the ability to adjust the height and length of the step. The module in this design can not only be rotated, but also the flange, which is a mount for the steps, can be deployed. Connections will not become loose despite use. threaded connection, because the load on the fastening is distributed differently.

No split pipes are used for this type of assembly.. All parts of the structure are secured with long pins that will bear the load. Assembling such a staircase can be difficult, but after the work is completed, all auxiliary elements will be hidden from view.

When installing the second type of assembly, bolts are used, although they can be used in other types. The bolts are placed between the steps. They are fasteners that enhance reliability.

Calculation

It is best to start installation work with calculations in order to be able to prepare everything necessary elements in advance. The easiest option is to use an online calculator. To calculate, you will need the height of the room where the stairs will be located, as well as the slope angle, etc.

The main parameter influencing the calculation is the location where the stairs are planned to be placed. The space occupied will be affected by the choice appearance stairs. Spiral staircase modular type is installed in an area of less than 3 sq.m. The width of the steps of such a staircase should be at least 10 cm. For more convenient operation, this parameter can be increased, but the occupied area will also be larger. It has wide steps of 12-15 cm, so it takes up a length of 4 m and an area of 7 sq.m. If the width of the steps is reduced, the operation of such a staircase may be inconvenient. Marching rotary a modular staircase will become the “average” option.

The angle of inclination of the stairs will also affect the final calculation. The most comfortable angle for lifting is 45°, but sometimes, to reduce the space taken up, they deviate from this parameter. The height of the riser and the length of the tread—the height and width of the step, respectively—will depend on its choice.

The height of the stairs will affect the calculation. It is determined by measuring the distance from the floor of the first to the floor of the second floor. This parameter will allow you to correctly calculate the quantity and dimensions steps. Selecting a suitable angle of inclination should also be done at this stage.

The most comfortable dimensions when designing:

step height – 17 – 20 cm;
step width – 20 – 26 cm;
The length of the step is different for each type of staircase. For the screw - 100 - 120 cm, for the march and march-rotary - 120 - 150 cm;
tilt angle 30° - 45°.

When using a special program, entering these parameters is necessary to create a future image of the staircase, which will be clearly shown in the picture and will allow you to decide on the changes that you would like to make to the final model.

Video instructions for assembling and installing a modular staircase

How to make a modular staircase with your own hands? Which designs modules possible? And, more importantly, is the game worth the candle? In this article we will try to answer these questions.

Simply put, a modular staircase is one that consists of a large number of identical elements. The most popular designs are those in which the joints between them allow the structural elements to be mounted at an arbitrary angle to each other. As a result, from one set structural elements a straight, L-shaped or spiral staircase can be created.

Clarification: modules for straight single-flight stairs are structurally simpler and provide a rigid connection with less load on the load-bearing elements. However, assembling a straight march from modules is, to put it mildly, a dubious idea. In this case, the complication of the design of relatively solid stringers ( load-bearing beams) is not justified.

Advantages and disadvantages

First, let’s figure out how meaningful this idea is to install modular stairs to the second floor with your own hands. Let us clarify: now we are talking about installing a finished structure, and not about independently manufacturing its elements.

pros

Assembly does not require welding skills or welding equipment.
The shape of the staircase can vary depending on the shape of the walls and your aesthetic preferences.
You do not need to look for a product that is exactly the same height as your ceiling.
The slope in many designs can also vary, which allows you to make the staircase either more convenient or more compact.
The design will inevitably be inferior in strength to an all-welded staircase. The abundance of movable and prefabricated connections and fixing screws means that under cyclic load the elements will begin to move relative to each other. Hence - gradual wear and the need to periodically tighten the connections.

Minuses

The price of a ready-made modular kit made in Germany for a 3-meter high ceiling starts from 200,000 rubles. Cheaper Chinese stairs, alas, are often made from low-quality steel and do not last long. At the same time, an all-welded staircase impeccable quality and with steps made of noble wood it will cost at least half as much.

Manufacturing and assembly

Is it possible to weld modular stairs with your own hands? How difficult is it to manufacture a single element of such a design? How to assemble finished staircase from such elements?

Let's look at a few design solutions.

All-welded module

The photo shows a staircase made of all-welded modules, viewed from below.

The element consists of two pipes, the diameters of which are selected in such a way that one fits into the other without a gap. A larger diameter pipe is cut along the longitudinal seam; On both sides of the cut, a rectangular corrugated pipe, cut lengthwise, is welded again. Through the holes, the professional pipe halves are tightened with bolts.

A flange with holes for fastening the step is welded to the upper end of the thinner pipe. The lower and upper modules are equipped with platforms for anchors, with which they are attached to the ceilings or ceiling and wall.

Assembly begins with anchoring the lower module to the floor. Then the remaining elements are installed sequentially; the top one is fixed with anchors. The tightened bolts ensure rigid fixation of the modules relative to each other.

Then the steps are attached to the flanges with screws or countersunk bolts.

Important point: if the staircase runs along the main wall, it would not hurt to secure the edges of the steps closest to it with corners. The structure will become much stronger and more stable.

The last thing to install is the fence. The simplest way attaching balusters to steps looks like this:

On a pipe with a diameter 1/2 – 3/4 inch long thread is cut.
A hole of the appropriate diameter is drilled in the step.
A locknut is pressed onto the thread of the future baluster, after which it is passed through the hole in the step and secured with a second locknut. It is worth considering that the strength of such a structure in relation to horizontal load is low and is limited by the strength of the wood of the step.

Clamping pipes

The design of the element differs from the previous one in that it uses two split pipes of the same diameter. The two elements are connected by a pipe of smaller diameter, which, as in the previous solution, is bolted inside the modules.

The pipe performs not only a function connecting element: it carries a flange to which the step is attached. Thanks to this design, independent adjustment of the height of the steps is possible.

The assembly instructions are practically no different from a staircase made from all-welded modules. The only difference is that here the design allows you to first rigidly fasten the lower and upper elements, and then connect them to each other.

Conclusion

Making a modular staircase yourself if you have welding skills is quite possible. However, the feasibility of choosing this particular design is a big question. In the video presented in this article you will find Additional information on this topic.

Good luck in construction!

Modular stairs to the second floor allow you to create any descent line. If during operation it is necessary to move the staircase to another area, it is enough to change the turn and shape of the steps at the turn point. As a result, the straight or rotary type staircase will take the desired position.

The staircase installation is made of supporting elements and stands for fastening the steps. The steps are usually wooden substrates. Among the main advantages are wide support plates for steps with stiffening ribs.

Modular staircase dimensions

Modular staircases in a house to the second floor are prefabricated structures, based on a stacked stringer. It is created in the form of modular parts made of wood or metal. Screw structures are placed on an area of 3 m2. The width of the steps is from 100 mm.

Attention! Marching staircase width from 1200 mm to 1500 mm occupies an area of 400 cm, which is 7 m3.

An alternative to the two options is a marching rotary design with given number platforms. They include from 3 to 8 steps.

Calculation of a modular staircase to the second flooris carried out taking into account the standardized parameters:

The normalized tread depth is from 200 mm to 260 mm. But options for 150 - 300 mm are acceptable.
Stair supports are supplied in different lengths. They look like a pipe round section for installation under stairs in several places.
The height between steps is from 170 mm to 200 mm. Height adjustment is made using bolts or rings.
Length of steps. For screw structures from 1000 mm to 1200 mm. For marching and winder structures from 1200 mm to 1500 mm.
Tilt angle from 30° to 45°.

Configuration and Mounting

DIY modular stairs to the second floorcan be assembled from different frames:

Straight/rotary.
Goose step.
Screw.

Fastening structures:

Prefabricated fastening type. Connections are formed by placing one module inside another. The fasteners are screws and plates. Externally, the product looks a little crooked, but it is assembled quickly and easily.

Spire. Connections are formed by threaded rods. When choosing this design, it is necessary to tighten the fasteners every few years. The assembly of such a structure is very difficult.

Clamp. The product allows you to adjust the length and height of steps. The module can be deployed in any direction. This type of fastening is particularly reliable.

Below are the optimal modular stairs to the second floor in the photo.

Module types

For assembly modular system pipes made of steel alloys are used. The creation of the frame is ensured by the sequential installation of individual parts and support posts into a kind of "ridge". The frame is the basis for fixing the steps that act as different breeds array. Next, balusters and handrails made of expensive or cheap materials are fixed.

There are 3 module options:

Cast or welded module. WITH different sides pipes of a given thickness and height are installed. By combining the long pipe of one module with the short pipe of the next part, it is installed in the selected position. Fixation is done by tightening the screws.
A simple version. The design consists of two individual elements: a welded part with 2 short pipes on the sides and a long pipe equipped with a flange (flat plate) to accommodate the step. At the intersection of the element with two side pipes, gaps are created for the tightening bolts. Usually, according to this scheme, it is built spiral staircase, since these installations can make turns relative to each other as desired.

Installation with clamping modules – perfect solution for screw structures. System includes big number individual parts that do not form welded seams. Connections are made using threaded rods. This is the most complex type of fastening, which is distinguished by its aesthetic properties, since the fastening is hidden inside the stringer.

There are wood products whose symmetrical parts have gaps on both sides to accommodate studs.

Selection of supports

The supports for universal stairs are intermediate pipes that support the base of the structure. They are installed every 4 to 7 modules, depending on the type of structure. There are also brackets, the fixation of which is carried out in relation to load-bearing wall. The frame is formed by support posts or mounted on brackets.

Supports are not used only when one side of the steps forms an emphasis on the wall. Mounting in in this case made with a corner or an anchor.

Installation of a modular system

Popular options include screw structures that can save space in the room. To perform the installation, the location of the central support, presented in the form of a vertical rod, is determined. It is necessary to pull two threads diagonally in the opening of the second floor, to which there is a flight of stairs.

From the intersection point, a plumb line is lowered indicating the location of installation of the flange (installation II). A thrust flange is mounted, which coincides in the center with the resulting point. Fastening is carried out using screws through existing gaps.

The correct placement of the first “guide” step is determined. To do this, place it on the floor. The step is then placed on the fixed flange along with the existing baluster. The central support rod is inserted into the flange through the first step. After placing the first stage, the vertical installation of the central rod is checked.

The first point for mounting the bottom flange with the module can be found by crossing the cords diagonally and plumb. The next step is placed on the vertical rod by another person positioned in the ceiling opening. After installing all the elements, the steps are tightened using nuts in the places provided by the manufacturer. Once completed, mounted on a rod landing and is fixed to the walls of the opening. Fencing, handrails and decor are attached.

Wall installation

The first module is fixed directly to the floor. Before this, you should measure the specified distance from the wall. The next module is taken and applied to the first. By analogy, the structure continues to grow upward. Before installing the final module, the correct fixation of the stringer is checked. The supporting and finishing element is applied to the surface.

Measurements are taken, a hole is made with a puncher, and then one is screwed to the floor and the other to the wall ceiling. Flanges are mounted. Gaps are created, applied to the module and the plates are tightened with screws.

Almost everything country houses have several floors, which actually distinguishes them from city apartments. For ease of movement between floors, stairs are used. The purpose of this familiar and simple design has not changed in any way over the years, but some changes have nevertheless occurred. It is worth noting that lifting systems have become lighter, more reliable, stronger, and new technologies and materials are used for their production. In addition, they have also been transformed externally due to updated architecture and design. In this article we will tell you how to make a modular staircase from metal yourself. The drawings and diagrams given here will make your work much easier.

Features, advantages and disadvantages of modular stairs

Installation of a modular staircase can only be done if you have certain knowledge in the construction industry. At each stage it is necessary to comply established rules, because incorrect assembly or connection of parts can lead to dire consequences in the future - not only breakdown of the system itself, but also injury to people. The quality of building materials is of particular importance here, because they must last as long as possible and not break or collapse over time under the influence of severe loads.

The main advantages of modular stairs:

Possibility of assembly without welding.
Variety of shapes. You can choose the appropriate configuration at your discretion, based on your own preferences, the shape of the room and your imagination.
You can assemble a modular staircase of any required height. Moreover, its slope can also be adjusted.
A wide variety of shapes and colors allows you to choose a model for any modern interior.

Disadvantages of modular designs:

Compared to solid models, modular structures are much weaker in terms of strength. Their butt joints gradually become loose, so the stairs have to be constantly inspected.
High price.

Types of modular stairs

Before installing a modular staircase indoors, select the most suitable look designs.

Today the following options are most often used:

Marching. This design is a straight staircase with wide steps. They don’t take up much space and are incredibly practical in terms of use. It is most convenient to climb along it.
Screw. They demand more less space, but in terms of descent and ascent they are not very convenient. Installing such a structure is quite simple; in appearance it looks incredibly attractive.
Rotary with intermediate platforms. These designs are the most practical, they also take up little space, and are comfortable in terms of descent and ascent. They are equipped with special turning platforms and two or more flights of stairs. Winder steps are sometimes used instead of steps.

Staircases are assembled using separate typesetting parts, which allows you to give the structure any the required form- screw, straight, at the required angle. To give it rigidity, a stringer is attached to the support modules at the top and bottom. Additional rigidity is provided by supporting pipes, which are mounted to the stringers every 1-1.5 meters.

Important! When installing such a structure, remember that the main thing is safety and convenience. That is why it is better not to make more than two turns of marches.

Assembly options for modular stairs

Today there are only three possible options installation of modular structures. So, in order for the assembly of a modular staircase with a turning platform to be successful, carefully study all the options in order to have an idea of their positive and negative qualities.

Module to module

In this case, a chain stringer of elements is installed according to the module-to-module principle, then each of them is fastened between two overhead plates with special locking screws.

They are the first among modular structures, even though they have some negative qualities:

Fixed step pitch.
The finished structure, as a rule, is slightly curved in appearance, which is impossible not to notice or correct.
Such stairs begin to sag during operation due to spontaneous loosening of the fasteners.

TO positive aspects this method installation can be attributed to the speed and ease of assembly of the entire structure.

Threaded rods

This option for connecting all elements of the staircase involves the use of threaded rods.

Unlike the first option, it does not sag, but has certain disadvantages:

Difficult to install.
Annual tightening and adjustment of fasteners.
Fixed steps.

Important! Welding allows you to significantly strengthen the fastening elements, which is especially important in cases where you do not plan to disassemble or move the ladder to another location in the future.

According to the clamp principle

This is the most modern way installation, taking into account all the shortcomings of the previous options. Positive quality it is considered the ability to adjust the length and height of steps. IN this option You can unfold the flange to install the step. In this case, the load is evenly distributed across the fastenings, due to which the fastening points do not become loose over time.

All elements of the staircase, instead of split pipes, are secured with long studs that take on the entire load. Their only drawback is the complexity of assembly.

Important nuances

In order for the new staircase to be used for a long time and not cause any complaints, the following points should be taken into account:

Before installing vertical supports, you need to prepare special concrete platforms so that they perform a load-bearing function.
Supporting side brackets can only be installed in concrete main walls with a thickness of at least 20 cm.
When installing stairs on a wooden floor, it is necessary to additionally strengthen the logs.

Important! It is necessary to take care in advance of preparing the site for installation of the structure so that those places where it comes into contact with the floor look aesthetically pleasing.

Self-production of a modular staircase

Of course, it’s easier to purchase a ready-made modular structure and then assemble it according to the instructions. But if you like to do everything yourself, then use the given recommendations for assembling stairs of this type. Let's take a closer look.

Preparatory stage

Create a floor plan of the room where you want to install the stairs. Make it to scale using a special program or graph paper.
Draw a side section of the room on the same paper and indicate the height of the ceiling. To make the calculation, use the starting and ending point of the flight of stairs, according to the floor level of the lower and top floor. Having obtained the width and height, calculate the length of the flight of stairs using the hypotenuse formula. Then the length flight of stairs divide by the permissible step height.

Important! Be sure to take into account the safe tilt angle of the structure from 30 to 45 degrees. Also calculate the number of steps.

Record your planned model. The steps are fixed approximately at a height of 15 cm from each other.
Place a horizontal projection of the steps on the floor plan.
Do general drawing modules identical in size and appearance.

Assembling the stairs

Now let's take a closer look at how to assemble a modular staircase from ready-made elements, according to instructions:

Decide what the steps will be made of. It is better to use hardwood for this. The thickness of one step should be 4-5 cm.
Make modules for installing steps. Order round modules from specialists according to your drawings if you cannot make them yourself at home. Square modules are best made from profile pipe 5 mm thick. Fasten the parts using welding and bolts.
Install load-bearing supports on concrete platforms. Concrete them after installation.
Using the drawings, cut required amount pipe parts of a suitable size.
In the cut parts that are ready for use, make holes for connection.
Mount the structure by attaching the structural modules to the load-bearing supports.
Carefully weld to the modules metal corners to strengthen the stairs.
Clean the structure from dirt and rust, then paint.
Install the finished steps.
Equip the staircase with a railing that perfectly matches the design and style.

Important! After completing installation, be sure to conduct a safety test of the ladder and only then proceed to use it.

One of the components of the ease of use of any multi-level residential property is the rational organization of movement between floors. Metal modular stairs have many advantages (durability, sufficient load bearing capacity with low weight and a number of others) compared to concrete and wooden counterparts, which is why they are so popular in private buildings.

Moreover, it is not difficult to make them yourself. You just need to follow certain instructions and draw up a drawing correctly. The modular (or spiral) version of the staircase is considered more promising, since the assembly process is significantly easier. This article will introduce you to all the nuances self-made modular metal staircase to the second floor

If you look at the available information on this request, you can conclude that each author interprets the concept of a modular staircase in his own way. Some imply a sliding (portable) or folding stationary structure, others - made of different materials.

And yet, most authors emphasize that this is a prefabricated version of the staircase, consisting of individual sections that are assembled into a single whole according to the principle of a designer. Next, we consider the specifics of manufacturing just such a modular staircase. All its components are made of metal. But the steps are your choice.

For residential buildings or multi-level apartments decorated in techno, hi-tech, loft styles perfect option- made of metal. If the dimensions are chosen correctly, a drawing is drawn up and everything you need is available, it will not take much time to assemble such a modular staircase with your own hands.

Design features of a modular staircase

The main load falls on two components - the lower one, fixed to the floor, and the upper one, fixed to the ceiling. They are connected by a metal stringer, on which they are installed additional elements– steps and fences.

A more common option is the installation of individual modules, which, when joined, turn into a full-fledged staircase. Drawing up a drawing involves independently calculating such characteristics as the length of spans, the number of steps, tread parameters, and so on.

That is why there cannot be unambiguous instructions for the manufacture of a modular staircase, since when developing its design, one should be guided by the specifics of the building in which it will be installed. For example, steps, unlike other parts, can be made of wood. You just need to correctly determine optimal thickness boards, in accordance with the expected load.

The only drawback of modular stairs assembled independently and without welding, using only bolts, is the need for regular maintenance of the structure. First of all, this concerns tightening all connections. But if you consider that the cost of such models starts from 42,980 rubles, then making them yourself has many advantages.

In addition, you should know that modular stairs come in several types. How are they characterized?

Screw.
In terms of operation (movement and movement of goods) - the worst of the options. The advantage is that installing such a model staircase does not require much space. Marching. As a rule, with one or two spans. The most
comfortable models , but differing in significant dimensions. For a small private house, especially a combined apartment, this is not the best solution. Rotary.

The best option

for a modular staircase, allowing you to choose the most suitable shape, steepness, number of landings, and so on.

Components and assembly features

Kosour

A structural element that is the basis of a modular staircase. To make it yourself, you should choose its chain version (the device is shown in the figure). One of the advantages is the ability to dock modules at different angles. This allows you to build a staircase of any shape and configuration, to suit the characteristics of a particular room.

There are two possible engineering solutions for a do-it-yourself stringer.

When drawing up a drawing of a model with brackets, it should be taken into account that to give strength to the entire structure, vertical supports must be installed approximately every 1.5 m. The only exception is for walls made of reinforced concrete or brick. And then, provided that the brackets are powerful enough.

Specifics of staircase assembly

Composite design

installation

Quick assembly of a modular staircase.
It is not possible to adjust the step pitch. Therefore, the drawing of a modular staircase must be drawn up as accurately as possible.
Difficult to achieve correct geometry self-assembled structure. Installation practice shows that some curvature of the stairs cannot be avoided.

The "clamp" principle

The technology is quite new, and therefore not often implemented. The difference is that all flanges are movable and can be rotated to a certain angle. This engineering solution allows for precise adjustment of the staircase to the installation site after all its components have been assembled. That is, change parameters such as the interval between steps and their length.

The procedure for assembling a staircase from modules with your own hands

Drawing up a drawing

All linear dimensions are in cm.

It is necessary to decide on the installation location of the stairs and take measurements of all the parameters of the room.

How to determine the number of steps

The size of the riser is usually taken to be about 20. Knowing the height of the room, it is easy to calculate the number of steps. If the result is a fraction, it is rounded to the nearest whole number. And between the floor and the first stage the interval increases slightly to level out the error.

The width of the stairs is 100.
The width of the steps (tread) is 30.

All that remains is to break the entire drawing into parts, each of which is a separate staircase module.

Preparation of components

steps

It is advisable to use wood for living space. The minimum board thickness for a modular staircase is 4. Ready-made steps can be purchased, so the owner will have to choose - purchase or cut, process the wood with his own hands.

Modules

The picture shows what is required to make them.

It's quite difficult to do on your own. It is advisable to order from a specialized workshop individual drawing. Alternatively, use a wall thickness of at least 0.5. But in this case, in addition to a drill (perforator), you will also need a welding machine.

Assembling the stairs

How exactly to make all the connections must be thought out at the drawing development stage. Fencing - at the choice of the master. It is not difficult to decide what technology to use to install it, depending on the parameters and shape of the modular staircase. .

After completion of the work, the design should be tested and all identified deficiencies should be eliminated.

Vertical supports are attached only to a concrete base or joists. The latter are necessarily reinforced with transverse bars. Fix the racks on the rough flooring, especially since finished floor it is forbidden.
A modular staircase is mounted on brackets only if the thickness of the adjacent wall is at least 200 mm.
To enhance wooden steps You can use metal edging from a small corner.
