Movement between floors in country houses is ensured by the familiar stairs. Their design has remained virtually unchanged since ancient times. But thanks modern trends has changed in design and architecture general form structures, and thanks to new materials, the stairs have become stronger, lighter and more reliable. The most striking example of stairs, combining tradition and modern materials, is a modular staircase. Creating a modular staircase with your own hands will not present any great difficulties, the main thing is to understand the order of work, be able to handle the tool, and also make a drawing with the necessary calculations.

From the outside, modular stairs for the home look airy and unreliable, but this is a deceptive impression. The materials used and the method of fastening ensure that modular stairs high level strength. In addition, another undeniable advantage of such a staircase is the small amount of materials used and the versatility of the design, which allows you to equip a modular staircase in a small area. All this and also modern design And affordable price make modular stairs very attractive for use in the interior.

Choosing a modular staircase

There is nothing complicated about how to choose a modular staircase. First of all, you need to focus on general style interior, own financial opportunities and the feasibility of its installation. It will be important to pay attention to the manufacturer of a particular staircase, as well as its type, the option of assembling the modules and their fastening.

Initially, modular stairs were produced in Italy, and then in Poland. Today, these countries still produce modular staircases for the home. Their products are distinguished by their elegance of form, quality and high price. Products from Poland are inferior to Italian ones, but overall the quality is high.

Over time, Russia picked up the baton. Various companies have launched the production of these ladders, one of which is Stamet. Stamet modular stairs have been produced since 2004, and the company is constantly working to improve their design. Thus, one of the developments of the Stamet company is the Prestige modular staircase, which is perfect for interiors where it is necessary to emphasize the status, refined taste and wealth of the owners. In general, modular stairs Russian production stand out for their reliability and affordable price.

Modular staircase"Premium" company Stamet:

China also produces modular stairs. But, unfortunately, in our market the lion's share of Chinese products is of poor quality and the only thing that attracts buyers is their low price. Find a quality factory modular staircase made in China It is possible, but you should be prepared for a fairly high price.

Modular staircase made in China:

When you start choosing a modular staircase, the first thing you need to pay attention to is the quality of the parts. After all, the reliability of the staircase itself and its external attractiveness will depend on this. It should be noted that the cost of a modular staircase directly depends on the materials used and the quality of workmanship. There is no clear answer to the question of how much a modular staircase costs. For modular stairs the price ranges from 200 USD. up to 2000 USD per linear meter. In this case, it is necessary to take into account the type of connection, material, and also the fact that first-generation stairs are cheaper.

The stringer modules of cheap stairs can be made from low-quality metal, which will lead to the staircase sagging during operation. A wooden elements Such stairs will not be properly processed. Ideally metal parts must be of sufficient thickness so as not to deform from slight effort, and the wooden elements must be free of any cracks or chips. In addition to the external component and high quality workmanship Another important factor influencing the choice of a modular staircase is its type. Below we will look existing species modular stairs, their pros and cons.

Having planned to create a modular staircase in your house, you need to decide what it should be like. Like regular stairs, modular ones can be of several types:

• marching, simple straight stairs with wide steps. They are very convenient for ascent and descent, but due to their design they take up quite a lot of space;
• screw stairs take up the least amount of space, but going up and down them is difficult;
• rotary with intermediate platforms. This type of stairs takes up relatively little space and is quite convenient to go up and down. They consist of two or more marches with turning areas.

But modular stairs have one characteristic What sets them apart from the rest is the chain stringer. It is the central element of the modular staircase design. The stringer itself consists of stacked parts that can be positioned either straight or at an angle, which allows you to make a staircase of almost any shape. The stringer itself is attached to the lower and upper support modules, which provide the necessary horizontal and vertical stiffness the entire structure. An additional element that adds rigidity to the entire structure is a support pipe installed every 1 - 1.5 linear meters. But if there is a solid wall made of brick or concrete nearby, then you can remove this element by securing the steps of the stairs to the wall.

In addition to those described above distinctive features For a modular staircase, there are three more options for assembling modules. Each of them has its own advantages and disadvantages that must be taken into account when choosing a ladder.

The first option for a modular ladder is to create a chain stringer by installing its parts “module to module” and securing them with two plates and locking screws. Such ladders belong to the first generation ladders and have a number of significant disadvantages. Firstly, the step pitch is rigidly fixed and cannot be adjusted. Secondly, after assembly there is a slight curvature that cannot be removed even by tightening the locking screws. Thirdly, metal has such an indicator as “fatigue”, and over time the fastening plates themselves unbend, and the ladder sag. Among the advantages, the simplicity and speed of assembling a modular staircase should be noted. A striking representative of the first generation of modular stairs is the Dream modular staircase. The photo demonstrating modular stairs shows how the string of stairs of the first generation is assembled:

The second option for assembling and connecting staircase modules is carried out using threaded rods. Such stairs do not have such a disadvantage of first-generation stairs as the curvature of the stringer, but this is more than offset by the complexity of assembling the stairs and the impossibility of adjusting the height of the steps. In addition, after a year and a half of intensive use threaded connections they become loose, and you have to tighten them, and this is a very troublesome task. A representative of stairs with a threaded connection is the modular staircase Unika. The photo demonstrating modular stairs shows how a string of stairs with a threaded connection is assembled:

The third version of modular stairs is the result of numerous modifications and improvements to previous models and represents the second generation with fastening of modules according to the clamp principle. The undeniable advantage of these stairs is the ability to adjust the height and length of the steps. In addition to the possibility of rotating the module, you can also rotate the flange itself to which the step is attached. Despite the fact that a threaded connection is used, in second-generation modular stairs the load on the fasteners is distributed differently, and the connections do not become loose over time. A representative of the second generation of stairs is the modular staircase TM “Our Ladder”. The photo demonstrating modular stairs shows how the string of stairs of the second generation is assembled:

Bolts can be used in all three options, but they are most often found in second-generation modular staircases. These simple fasteners, placed between the steps, increase the reliability of the entire staircase.

Calculation of a modular staircase

The creation of a modular staircase begins with the design and calculation stage. For these purposes, you can use a special computer program, such as ArchiCAD. Of course, to use it you will need a certain skill and experience, but with a little desire, even a beginner can do the calculation of a modular staircase. Another option to help with calculations is online calculator s. They can be found on the Internet; the interface of such a calculator is intuitively simple and clear. It is enough to enter all the necessary data - the height between floors, the angle of inclination, etc.

When performing calculations yourself, it is necessary to take into account a number of factors that influence the choice of the type of staircase. The main parameter influencing the choice is the space allocated for the stairs. Based on this, it is worth choosing a modular staircase. For ease of calculation, there are a number optimal parameters that are suitable for a certain type of stairs. Spiral modular staircases it is preferable to install on an area of ​​less than 3 m2, and the width of the steps should be at least 100 cm. Of course, the width of the steps spiral staircase can be increased, and the area it occupies will immediately increase. If you want to install staircase with wide steps from 120 cm to 150 cm, you will have to prepare a space more than 4 m long and 175 cm wide, which is about 7 m2. If it is less, then the stairs can turn out to be very steep. The way out of the situation when the space is less than 7 m2, but more than 3 m2, is to arrange mid-flight rotary modular staircase with one or more sites.

Another key factor in the calculations is staircase angle. Thus, an angle of 45° is considered the most convenient, but there are times when it cannot be maintained. Two more initial parameters depend on the angle of inclination of the stairs. This is the height of the riser and the length of the tread, in other words, the height and width of the step. The table below shows these dimensions depending on the angle of inclination.

The next parameter required for calculations is height of the staircase itself. Everything here is extremely simple. To do this, it is necessary to measure the height from the floor of the first floor to the floor level of the second floor. This is needed to calculate total steps and their sizes, as well as select the most optimal angle of inclination.

Modular staircase: dimensions, which are considered ideal:

• step height from 17 cm to 20 cm;
• step width from 20 cm to 26 cm;
• The length of the step depends on the type of staircase. For screw from 100 cm to 120 cm. For marching and marching-turning from 120 cm to 150 cm;
• tilt angle from 30° to 45°.

As a result, after entering all the necessary data, the program will create a model of the staircase, which you can review and make changes if necessary. It is most convenient to design a staircase at the same time as designing a house. This makes it easier to take into account all the details. If you don’t want to do such a project yourself, you can turn to specialists. Moreover, companies that produce and sell modular stairs make a drawing for free when ordering a staircase.

How to make a modular staircase

Having a ready-made project in hand, you can go in several ways. The first is to place an order for the stairs from the manufacturer according to the project. The second is to look in stores for all the components of a modular staircase and purchase them. The third is to make the modules yourself. Which one to choose is up to you to decide. The simplest and reliable way- this is to place an order from the manufacturer. As a result, you will be delivered a ready-made staircase, manufactured in compliance with all norms and rules; all that remains is to assemble it on site, and this does not require any special skills.

The first thing you have to do is install and secure to the floor the first module of the staircase, which is its base. To do this, measure the required distance from the walls and make notes.

Important! All dimensions and calculations must be in project documentation, prepared earlier.

Now, having placed the module in the right place, we make notes for the holes. Then we take a hammer drill and drill holes for fasteners. We install the base of the stairs in place and secure it. Further assembly work will consist of installing subsequent modules into each other.

Having installed the penultimate module, we check that all modules are installed correctly. This is necessary to maintain the geometry of the stringer and so that you do not have to redo the fastenings for the finishing module. If everything is in order, put the finishing module in place. After which, pressing him to interfloor covering or wall, we mark places for holes for fastening. We remove the finishing module, drill the holes, return the module to its place and secure it. Next, using locking screws, we fix all parts of the stringer.

Further work consists of installing flange plates on each module. There is nothing super complicated here. The plates have 8 holes, 4 of which are intended for fastening to the stringer modules. Simply attach the plate to the module and fasten it with 4 screws.

All that remains is to install the steps in place. For this first, if this wooden steps, put them in place. We center and mark the locations at the bottom for the holes for fasteners. Then we drill it with a drill 1 mm smaller in diameter, put it in place and screw it on.

Important! If the staircase design does not provide rigidity posts, then the steps must be secured additionally to the wall. Regular corners are suitable for this. They are installed under the step to the wall. First, we put them in place, mark and drill points for fasteners, and then secure them.

Finally, we install handrails and bolts. Their installation is carried out after the steps have been fixed. You will have to make through holes in the steps themselves, but after installing the railings and railings, the entire staircase structure will receive additional strength.

The installation steps described above are suitable for first generation stairs. The video demonstrating modular stairs shows how to install a second generation modular staircase. After watching this video, there will be no questions left about how to make a modular staircase with your own hands.

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.

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

Modular staircase dimensions

Modular stairs 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 structure with a given number of 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 fastenings are particularly reliable.

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

Module types

Pipes made of steel alloys are used to assemble the modular system. The creation of the frame is ensured by the sequential installation of individual parts and support posts into a kind of “backbone”. 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 separate 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. Typically, a spiral staircase is built according to this scheme, since these installations can make turns relative to each other in any way.

• Installation with clamping modules – perfect solution for screw structures. The system includes a large number of 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. In this case, fastening is done with a corner or an anchor.

Installation of a modular system

Popular options include screw structures that can save space indoors. 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. Upon completion, the landing is mounted on the rod and 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.

Every person wants to make their home beautiful and cozy. The solution to this problem for owners country house or cottage is not complete without choosing the design and design of the staircase. One of the options offered by manufacturers today is a modular staircase. It is convenient, practical, modern design, which will successfully complement any interior. A little more about modular stairs.

Modular stairs were developed by Italian designers. Currently, they are being improved and produced, both budget and luxury luxury options.

Modular stairs are installed, and a private house, and into a two-level apartment.

The design of a modular staircase includes a high-strength metal frame, which is assembled from individual parts (modules) and consists of a stringer, supports that strengthen the stringer, steps and handrails. In most designs, metal carcass located along the middle line of the stairs. There are also design options with two stringers.

Advantages of a modular staircase:

• Durability, service life can be more than 100 years;
• Reliability, modular connections do not loosen or weaken;
• Quietness, unlike wooden stairs, which creak;
• Sleek design, especially compared to concrete stairs;
• Easy to assemble; 2 people are enough to assemble the structure;
• Easy to maintain.

Modular interfloor stairs included in the state register No. 35530 and can be straight (flight), rotary (L-shaped, U-shaped) or screw. The rotation is performed by 90ᵒ, 180 degrees and any other amount using rotary (winder) steps, or an intermediate platform is installed.

Design options for stairs to the second floor can be seen, for example, in the Stolaris catalog on page 134.

Component modules for assembling stairs

The main element of a modular staircase is a prefabricated metal frame. By building it yourself, you can save a lot of money. Assembling a modular staircase is not difficult. To build the frame, you will need detailed instructions, a good assistant and a set of tools.

Prefabricated modules can be of various designs:

• Glass in glass - modules are placed one inside the other, assembly starts from the bottom, the step size is not adjustable;
• Module-clamp - the structure begins to be installed from the top, each module is inserted and tightened, the step height can be adjusted;
• Cast modules, made by casting;
• On two stringers, stamped, usually Chinese stairs;
• Wooden modules;
• Modules of original shape, curved, arc.

Each design has its pros and cons. Assembling a glass into a glass is more reliable, but due to the impossibility of adjusting the step height, you need to carefully determine the dimensions of the stairs, length, angle of inclination, number of steps.

When assembling the module-clamp and when servicing the stairs, it is necessary to periodically tighten the connections.

Assembling a modular staircase begins with the upper starting module, which is attached to the ceiling just below the floor level of the upper floor. The intermediate standard modules are then inserted into the starting module one after the other. During operation, the height and level are controlled. At the required stage, according to the diagram, the support module is attached and the support is installed. At the end, the lower finishing module is attached. No special knowledge or skills are required when installing a modular frame; everything is done according to the diagram and instructions.

Step options for modular stairs: materials

To save money, you can make the steps yourself or use those offered by the manufacturer. In accordance with the requirements of strength, reliability and aesthetics, the material of the steps is chosen.

Step options for modular stairs:

• Wooden;
• Glass;
• Plastic;
• Metal;
• Marble.

Steps are being fulfilled a certain shape and sizes. To perform a turn, they are made winder steps, narrowed on one side. It is important that in the middle part such steps have a depth that is comfortable for walking. The first 2 or 3 steps from the bottom may differ in their shape and be slightly wider. When installing duck step steps, install the right-hand step first.

To make the stairs comfortable and safe, the steps must be at least 0.8 m long and 0.28-0.3 m deep.

To determine all the necessary parameters, the staircase is calculated and a project is drawn up.

We carry out online calculations of modular stairs before installation

The modular staircase can be made to order, or you can choose finished design. Ready-made stairs are not always of the appropriate quality, and sometimes difficulties arise with how to carry out installation. When making a product to order, the manufacturer takes into account all the client’s wishes and tries to implement the most creative ideas.

On the websites of companies offering stairs, calculations are performed online. The customer is only required to enter some dimensions and select a design option. If in doubt, you can ask a question online or call a surveyor to your home.

Data that is entered into the online calculator to calculate a modular staircase:

1. The height of the staircase is measured from the floor level of the lower floor to the floor of the upper floor, taking into account the finishing.
2. Stair width accepted equal to length steps.
3. Type of staircase construction.
4. Material and shape of steps and railings.
5. Dimensions and shape of the opening or balustrade.
6. Personal wishes and comments.

After entering all the necessary data, the customer leaves the address Email or number mobile phone and receives calculations and a design of the desired staircase, as well as its planned cost.

At independent execution calculations of a modular staircase, special programs and standard files with the qsd extension are used. When making calculations, you must remember the safety requirements that any staircase, including modular ones, must meet.

A comfortable staircase should have an inclination angle of 30–40ᵒ and step sizes appropriate medium length step.

It is also important to take into account the dimensions of the upper floor opening. Small errors in calculations can be corrected when installing the modular staircase structure. Some manufacturers' websites offer step-by-step instruction calculation of a modular staircase.

Modular stairs: reviews

Reviews about modular stairs are very different. Good feedback left by buyers of the Lesenka company, which has a chain of stores throughout the country.

Advantages of modular stairs noted in reviews:

• Beautiful appearance, light, airy design;
• Compact, disassembled staircase is easy to transport;
• High-quality components;
• Easy to assemble;
• Affordable price.

Some forum participants spoke unflatteringly about modular stairs, complaining about low-quality elements and difficulties in assembly. These shortcomings are often found in cheap Chinese-made stairs.

Construction of a country 2-3-storey mansion or townhouse, even a small one attic house predetermines the need to build a staircase. The design, which ensures comfortable safe movement, also performs a decorative function. Natural requirements for it are not only aesthetics and reliability, but also the ability to create an optimal configuration. That’s why most people prefer to install modular stairs to the second floor or to the attic: they meet the entire list of consumer requests. In addition, it is easy to build a module consisting of architectural element possible without resorting to the services of builders.

Modular staircase structures were invented in the 80s of the last century in Italy. After launching on the domestic market, they almost immediately began to actively displace massive analogues made of concrete and other materials.

Modular stairs to the second floor, to the attic or to the utility room are built in country mansions intended for permanent residence, V two-level apartments, at the dachas

A reasonable explanation for the popularity is included in the list of advantages, these are:

• affordable price for most citizens;
• the ability to independently install and build modular stairs with your own hands, without any skills or experience;
• successful compatibility with the prevailing majority finishing materials and interior elements;
• the ability to assemble a straight, U-shaped, screw, angular, or structure combining several configurations from modules;
• arrangement of premises with any ceiling height.

Modular stairs - photos of options for using different components: steps, fencing elements, handrails

The modular principle allows owners to choose the best option for handrails and additional elements, in a number of modifications, allows you to vary the height of the steps, adjusting the given size to the physical parameters of the users.

Modular designs can be adjusted to the physical parameters of users by varying step and tread sizes

Varieties of design and different assembly methods

Stylish, one might say, elegant modular stairs for a country house - best option, combining strength with reasonable space savings. Universal systems are suitable for arranging as presentable living rooms, and household premises. They are attractive due to their simplicity of design and simple fastening technology.

What is a modular staircase?

“Modular” is a defining word that expressively characterizes the concept. A modular system is assembled from matching parts, the first and last of which are attached to the floors and take on all the brunt of the main load. Between them there is a strong metal frame (chain or spinal stringer), it is intended for mounting steps.

Assembling a modular staircase: top view to understand the principle of modular connection

Note. A “guide” step must be installed on the first module attached to the base or landing.

The number of middle modules is calculated based on the interfloor distance, geometric parameters structure and a given angle of inclination, according to which the installation of a modular staircase with U-shaped, straight or angular geometry will be carried out. The height of the screw structure is calculated based only on the distance between the floors.

Types of modules and their differences

To make modular connections, pipes made of ultra-strong steel alloys are used. In fact, the most critical stage is the construction of the frame, that is, the sequential installation, combination and careful fastening of modular parts and supports into a kind of “backbone”. Steps are attached to a correctly mounted frame, for the production of which both expensive and cheap types of wood are used. Then balusters and handrails are installed; they can also be made of expensive or budget materials.

A module is a component of a backbone-like body, sequentially assembled from these elements - a stringer

High-quality assembly of a modular staircase guarantees the durability of the structure and operational safety. This process requires scrupulous adherence to the instructions included with the finished kit and responsible execution. There are three types of modules for constructing stairs, depending on which the assembly and connection are performed.

• Cast or welded module, with pipes located on two opposite sides different diameters And different heights. After aligning the long pipe of one module with the short pipe of the next element and installing it in the position required by users, the connection is fixed by tightening the screws.

Modular staircase for a summer house, country house with fixing screws

• A module consisting of two separate components: a weldment with two short pipes on each side and a long pipe equipped with a flange (flat plate) to secure the step. On the bridge of the part with two side pipes there are holes for tightening bolts. Most often, a modular spiral staircase is built according to this scheme, since similar modules can be rotated relative to each other in any way you like.

Design with clamped modules - the best option for constructing a spiral staircase

• Module from large quantity individual elements that do not have welds. The parts are connected to each other using threaded rods. This is the most difficult option to install, but the most aesthetic, since all the fasteners are hidden inside the stringer.

Modular stringer, the elements of which are connected by pins, all fastening elements of which are hidden from view

There are also wooden ones modular systems, the symmetrical components of which are equipped on both sides with holes for installing a metal pin in them.

Types of supports for modular stairs

Universal metal modular stairs must have supports, which are used as:

• intermediate pipe-racks resting on the base; they are installed every 4 – 7 modules, depending on design features;
• brackets, which are attached to the load-bearing wall.

The frame of a modular staircase must necessarily have supports or rest on a bracket

You can not use supports only when one edge of the step rests on the wall to which it is attached using a corner or anchor.

When choosing modular stairs for a summer residence, owners predominantly give preference to screw structures that occupy a minimum of usable space. The technique of their construction cannot be called extremely simple, but a person who knows how to use the tool, head and instructions can cope with the installation. However, he will need a partner to complete the assembly. Sequence of work:

• Let us determine the location of the central support, which is a vertical rod. To do this, pull two cords diagonally in the opening of the upper ceiling, to which the stairs should lead. A plumb line descends from the point of their intersection; it will indicate the installation location of the thrust flange (II design).
• We mount a thrust flange, the center of which should coincide with the found point. Fixation is carried out using the screws supplied with the kit through the holes provided for them.
• Let's determine the position of the first “guide” step by first placing it on the floor. After which the step must be put on the fixed flange along with the baluster already installed on it. Then we insert the central support rod into the flange through the first stage.

Attention. The vertical installation of the central rod must be checked after installing the first and each subsequent stage.

Installation of a modular screw structure: the first point for installing the lower flange with the module is found by crossing the cords diagonally and plumb

• The next step should be placed on the vertical rod and helped to lower down by a partner located in the opening of the ceiling. Further in a similar sequence. All steps must be firmly tightened with nuts in the places specified by the manufacturer.
• Having completed the installation of the entire number of steps, we mount it on the rod landing and attach it to the walls of the opening.
• Finishing touches– fastening of fencing elements, handrails and decor, if any.

Compact modular staircases are shown in photos in a variety of variations. There are, perhaps, no premises at all that cannot be equipped with their help. By thoroughly following all the points of the instructions, anyone can provide their country house with a reliable, durable staircase.

A modular staircase is a structure consisting of identical parts fastened together (modules with steps) attached to a central stringer. If desired, you can make such a staircase yourself.

Features, pros and cons

Peculiarities

A modular staircase usually has a semicircular shape. To accommodate such a structure you need quite a lot free space. However, this does not mean that the finished staircase will look too bulky. The design is neat and “airy”; the assembly features allow you to give the staircase almost any shape.

Before you get started, check out the benefits and weaknesses modular stairs.

Advantages

Flaws

Modular stairs are not without their drawbacks. First of all, the modular design is inferior to all-welded models in terms of its strength characteristics. All prefabricated connections will gradually become loose, so the owner will have to regularly monitor the quality of the structure and tighten the connections.

The second big disadvantage of modular stairs is the high cost of ready-made kits. However, here are instructions for your attention: self-assembly designs, therefore this disadvantage is not relevant. The main thing that starting materials were of the highest possible quality.

Before you start arranging the stairs, select suitable option modular type designs. There are these types of modular stairs:

• marching. Conventional straight designs with the simplest wide steps. Very easy to use and reliable, but rather bulky and non-compact;
• screw. Occupy minimal space, however, they are not as convenient in terms of use as flight stairs;
• rotating with platforms. They take up relatively little space and are quite comfortable. They have 2 or more flights with intermediate turning areas.

What you need to know about the stringer?

Regardless of the type of modular staircase you choose, you will have to become familiar with the main element of the design in question - the chain stringer.

The stringer is the main central component of the type of stairs under consideration. It is assembled from a number of assembled elements, the installation of which can be carried out directly or at some angle, which gives the owner the opportunity to create stairs of a wide variety of shapes.

The stringer is fastened to supporting modular elements at the top and bottom, thereby achieving the required rigidity and strength of the structure.

For additional rigidity, a support pipe is included in the structure every 100-150 linear centimeters.

If there is a strong concrete or staircase near the staircase location, brick wall, from the use of additional elements modular design you can refuse by fixing the stair steps directly to the wall.

Stair assembly options

There are several methods for assembling stair modules. Each of existing options is characterized by its strengths and weaknesses, which you need to know about before starting to independently assemble a modular staircase.

"Module to module"

The stringer can be assembled using the “module to module” method with additional fastening using plates and mounting screws. This is the first generation of such stairs with many disadvantages, including:

• strictly limited step pitch. This step cannot be adjusted;
• some curvature of the assembled structure. It is impossible to get rid of this defect even by tightening the screws;
• relatively low durability. Over time, the fastening plates begin to unbend on their own, which leads to sagging of the entire structure and causes additional inconvenience.

The only advantages of this option are high speed and extreme ease of assembly.

Threaded rods

This method involves the use of threaded rods during the assembly process. Such ladders do not have the disadvantages characteristic of the previous design, however, assembly with threaded rods is quite complex. The height of the steps still cannot be adjusted. Every 1-2 years you will need to tighten loose threaded connections, and this also causes a lot of trouble.

Based on the clamp principle

These are stairs of a new generation. Among the main advantages of this option, it is necessary to note the possibility of changing the length of the step and the distance between the elements. Modules and flanges can be deployed.

The load distribution on the fastening elements is organized using advanced technology - the connections do not become loose over time.

Each of the stairs discussed above can be assembled using bolts - these are elementary fasteners installed between individual steps and helping to increase the rigidity and reliability of the structure. Most often, bolts are used in the latest generation of stairs.

Important Notes

To ensure that your modular staircase lasts as long as possible without complaints, remember the following tips:

• vertical supports must be installed on pre-poured concrete platforms. They will serve as a foundation;
• the staircase can only be paired with a main wall with a thickness of 20-25 cm;
• When installing a modular staircase on a wooden floor, the logs must first be reinforced with cross bars.

Preparatory stage

On preparatory stage you have to perform a number of calculations and prepare the necessary drawings.

First step. Create a drawing of the room in which you plan to place the modular staircase. It is most convenient to make such drawings to scale on graph paper or in a special program.

Second step. Measure the height of the room. Draw a section of the room along the height near the previously drawn up room plan on a piece of paper. Mark the lines of the floor and ceiling of the room in the drawing.

Third step. Schematically draw a modular staircase. The steps will be fixed at a distance of about 15-16 cm. The drawing will help you determine the required number of steps. If the top step has an unacceptably small height, the “excess” must be evenly distributed over all steps of the staircase.

For example, the floor has a height of 280 cm. You make 15-centimeter steps. Simple calculations show that there will be not a whole number of steps, but, specifically in this case, 18.6 pieces. In this example, you need to make 18 steps, increasing the distance between individual steps to 15.5 cm.

Fourth step. Draw a horizontal projection of the stair steps on the room plan. Optimal width modular staircase - 100 cm. It is better to make steps about 30 cm wide.

Fifth step. Prepare a drawing of the modules for attaching the steps of the stairs. Each module must have the same dimensions and shape. If you plan to use ready-made modules, this drawing will not be needed.

Main stage

First step. Prepare the material for making the steps of a modular staircase. It is advisable to use solid wood. Optimal thickness boards - from 4-5 cm. Use screws and glue to connect boards. If you wish, you can purchase steps from finished form. At this point, focus on your personal preferences and the characteristics of your specific situation.

Second step. Prepare modules for attaching the steps. It is almost impossible to make round modules at home without the appropriate skills. Therefore, it is better to immediately order their production from a specialized company according to your calculations and drawings.

You can make square modules yourself. Use for this profile pipes. Pipes with walls with a thickness of 0.5 cm or more are suitable. Use bolts and welding to connect elements.

Third step. Prepare concrete platforms for installation of load-bearing supports. These supports should be immediately concreted into the platforms.

Fourth step. Slice suitable pipe on required quantity parts in accordance with previously prepared drawings.

Fifth step. Make holes in the prepared elements for bolted connection modules.

Sixth step. Assemble the entire structure, attaching the staircase modules to the supports in parallel.

Seventh step. Strengthen the system by creating some neat welds. At the same stage, weld the metal corner to the staircase modules if you want to create such a edging for the steps.

Eighth step. Paint the metal elements of the structure, having previously cleaned them of rust.

Ninth step. Install the steps.

Tenth step. Install fencing. It can be forged or wooden. Choose according to your taste.

At the end, all you have to do is once again verify the quality and reliability of all connections and test the assembled structure. At this point, the do-it-yourself modular staircase is ready. As you can see, there is nothing complicated in its assembly. Follow the instructions and everything will definitely work out.

Good luck!
