DIY modular staircase made of metal - drawings. We make a drawing and assemble a modular metal staircase with our own hands. How to make modules for the stairs yourself

Modular staircase is one of the most important structures house or apartment, designed to connect two floors to each other. She happens to be mandatory element architecture and part of the design, must be in combination with the interior of the room, creating a single architectural ensemble with it.

A modular staircase can be assembled with your own hands if you have some knowledge in the field of construction. But at all stages it is necessary to adhere established rules. Incorrect installation or connection of parts can, over time, lead to creaking of the structure, its failure, or injury to people. An important role is played by high-quality building materials that will last a long time and will not begin to break and collapse over time under the influence of loads.

U modular staircase there are several significant advantages over other types of stairs:

• assembly is possible without welding;
• may have different shapes. Based on the shape of the room, your preference and imagination, you can choose the desired configuration;
• staircase modules can be assembled to whatever height is needed. In this case, the slope of the modules is adjustable.

There are a number of disadvantages that are worth paying attention to:

• the modular design is somewhat weaker in strength compared to solid models. Butt joints may become loose over time, which requires periodic inspection of the structure;
• high price.

Kinds

Before starting installation indoors, select the right type designs. Are used the following types modular stairs:

Stairs are assembled using separate prefabricated elements. This will allow you to make a structure of any shape you need: straight, screw, at the desired angle. For rigidity, the stringers are attached at the top and bottom to the support modules. For additional rigidity, every linear 1-1.5 meters a supporting pipe is mounted to the stringer, which is attached to the floor or a support bracket with mounting to the wall.

Important! When installing a modular staircase, remember that the main thing is convenience and safety. Therefore, try not to make more than 2 march turns.

Assembly options

There are three main options for installing modular structures. In order to assemble a modular staircase made of metal, you need to carefully study all the options, since they have positive and negative aspects.

Module to module

The chain stringer is assembled from elements according to the “module to module” principle, after which each element is secured with two overhead plates with locking screws. These stairs are the first of a line of modular ones, but they have some negative qualities:

• have a fixed step pitch;
• the assembled staircase has a noticeable slight curvature that cannot be removed;
• During operation, such a structure begins to sag due to spontaneous loosening of fasteners.

Positive quality This installation option is simple and quick to assemble the entire staircase.

Threaded rods

In this embodiment, the connection of the staircase elements is carried out using threaded rods. Unlike a chain stringer, the ladder does not sag, but has minor disadvantages:

• complexity of installation;
• fixed steps (as in the “module to module” option);
• annual adjustment and tightening of fasteners.

Idea! Fasteners can be strengthened by welding. This is only relevant if you do not plan to disassemble and rearrange the stairs in the future.

Based on the clamp principle

A modern method that took into account all the shortcomings of previous generations. A positive quality is the ability to adjust the height and length of the step. In this version, the flange for mounting the step can be unfolded. The load on the fastenings is distributed evenly, so the fastening points will not become loose. Instead of split pipes, the staircase elements are secured with long studs that take the load. The disadvantage may be the difficulty of assembling this version of the stairs.

Installation of the above options is carried out using bolts. These fasteners are mounted to distribute the load along the edges of the steps, which increases their rigidity and reliability of the entire structure.

Important Notes

In order for the ladder to be used for a long time and not cause any complaints, the following notes must be taken into account:

• Before installing vertical supports, it is necessary to prepare for them concrete platforms. They will serve as a load-bearing foundation;
• side support brackets may only be mounted in a concrete main wall with a thickness of 20 centimeters or more;
• if the ladder is mounted to wooden floor, then the logs must first be strengthened.

Making a modular staircase with your own hands

The easiest way is to buy a ready-made modular structure and assemble it like a structure. However, if you are used to doing everything yourself, you will need some assembly guidelines of this type stairs. So, let's figure it out.

Preparatory stage

1. Make a plan of the room where the stairs will be installed. It is recommended to make the plan to scale using a special program or graph paper.
2. On the same paper, draw a side section of the room indicating the height of the ceiling. To calculate, it is necessary to take the starting and ending points of the flight of stairs at the level of the floors of the lower and top floor. Having the height and width, using the formula for calculating the hypotenuse of a right triangle, we calculate the length of the flight of stairs. In this case, it is necessary to take into account the safe angle of inclination of the stairs from 30 to 45 degrees. After this, we calculate the number of steps. Length flight of stairs divide by permissible height steps.
3. Draw the planned model. Approximate fixation of the steps is carried out at a height of 15-16 cm from each other. If the last stage has some average height, then this distance is equally distributed among other steps.
4. Place a horizontal projection of the steps on the floor plan.

Regardless of the purpose of the ladder and the materials from which it is made, it must comply regulatory requirements, which are used during design and calculation:

• the width of the stairs must be more than 90 cm;
• the angle of inclination of the flight of stairs should be within 30-45 degrees, which meets safety and ergonomic requirements;
• steps must have a depth of at least 27 cm;
• the distance between the fence supports should not exceed 15 cm (if there are children - no more than 12 cm);
• the side guard must withstand a load of at least 100 kg.

1. Execute general drawing staircase modules, identical in appearance and size.

Main stage

The following actions must be performed in the given sequence:

1. It is necessary to decide what material the steps will be made of. The best option is steps made of hard wood. The average thickness of the step is 4-5 cm.
2. To install the steps, make modules. IN living conditions making round modules is quite problematic. It is more convenient to order them from specialists based on your drawings. To make square modules in domestic conditions, you will need a profile pipe with a thickness of more than 5 mm. The parts are fastened using welding and bolts.
3. Install the load-bearing supports on concrete platforms. After installation, the supports must be concreted.
4. Based on your drawings, cut from a suitable pipe required quantity parts.
5. Make connecting holes in the cut and ready-to-install parts.
6. Mount the entire structure, attaching the structural modules to the supporting supports.
7. If necessary, you can strengthen the structure by welding neat metal corners to the staircase modules.
8. Paint the stairs to remove any rust and dirt.
9. Install pre-prepared steps.
10. Equip the staircase with a railing that you can choose based on your liking and design.

Assembling a finished modular staircase

Assembly of a finished modular staircase ( screw design)

Having completed the installation, it is necessary to conduct a safety test of the structure and you can begin to operate it.

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.

Peculiarities

A modular staircase usually has a semicircular shape. To accommodate such a structure you need a lot of 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 high price 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 . They take up minimal space, but are not as convenient to use as marching 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 use 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 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 ladder may only be paired with main wall thickness from 20-25 cm;
• when installing a modular staircase on wooden floor the logs must first be reinforced with transverse 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 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. Apply horizontal projection stair steps to 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.

Load-bearing units - modules

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 sites for installation load-bearing supports. These supports should be immediately concreted into the platforms.

Fourth step. Cut a suitable pipe into the required number of pieces in accordance with the previously prepared drawings.

Fifth step. Make holes in the prepared elements for bolting the 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 metal corner to the staircase modules, if you want to create such a edging of steps.

Eighth step. Paint metal elements structures, 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!

Video - DIY modular staircase

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 it is important appearance. 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 because frequent use 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 rarely 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 under anchorage 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 that have 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 improvements. 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 may cause difficulties, but after completion of the work everything 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 influenced by the choice of staircase appearance. 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. Choose suitable angle tilting also follows 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.

The interfloor staircase is one of the most important structures in the house. It not only serves as a bridge between two floors, but also greatly influences the appearance of the interior surrounding it. Massive staircases look very beautiful and reliable, but there is not always room in the house for such structures. That is why such majestic but bulky structures are being replaced by no less attractive, but more compact modular staircases.

Modular staircase structures first appeared in Italy in the 80s. Such stairs reached us relatively recently and immediately won the love of most consumers.

Stairs of this type are included in State Register. They can be marching, screw or rotary. Successful examples You can see such designs in the Stolyaris catalog.

Modular stairs are assembled from individual elements. Due to what they can have the most different shapes and configurations. Such structures are even more popular than their concrete counterparts. All thanks to the fact that they have a fairly large list of advantages.

Advantages of modular stairs:

1. The cost of staircases made from modules is much lower than concrete structures. Therefore, modular products are becoming available to the masses.
2. The modular staircase is so easy to assemble that even a person with no experience in construction can install it with their own hands.
3. Prefabricated modular stairs go well with all interior styles. However, in rooms with modern design such structures look like an integral part.
4. From the same modules you can assemble structures leading to the second floor of various shapes. These can be straight, spiral, or corner stairs.
5. This ladder will fit perfectly into a room with any ceiling height. You can adjust the height of the structure yourself by adding or removing modules.
6. Staircase structures made from modules take up much less space than concrete marching structures. The free space under such interior elements can also be used.

Interfloor modular stairs will fit perfectly into absolutely any room. They do not take up much space and are very convenient to use. With a little imagination and patience, you can create a high-quality and aesthetic design without any problems.

Accessories for modular prefabricated stairs

To understand whether modular stairs are right for you, you need to understand what they consist of. Having heard the name of such structures, one can understand that the main element of such a structure is the modules from which the frame is formed. They can be of many different types.

Types of modules for stair frames:

1. Glass to glass modules are assembled from the bottom up. In this case, one element is inserted into another, and the step size is not adjustable.
2. Clamp modules are inserted into one another from top to bottom. At the same time, the elements are tightened, thanks to which you can adjust the step height.
3. Cast modules are made by pouring metal into the desired shape.
4. Modular stairs with two stringers are usually made in China.
5. You can make wooden modules with your own hands. However, such work will take a lot of time.
6. Modules of the original form are more expensive, but they look much more interesting than conventional designs. They can have an ornate or strict geometric shape.

Each of the options is good in its own way. To decide which one will fit better into your home, you need to draw up a competent design project in advance.

In addition to modules for the frame, the package of such stairs includes steps. They can be made of materials such as marble, glass, plastic, metal and wood.

You can make the steps yourself or order them from companies specializing in their manufacture. In any case, the shape and size of such structures are adjusted to the type of frame that you assembled from the modules.

Steps for stairs with a 180-degree turn can be narrowed on one side. However, in the central part they will in any case have parameters convenient for climbing stairs.

Thus, the width of the steps will always be more than 80 cm, and the depth will vary between 28-30 cm. These dimensions are considered the most convenient for use.

Types of modular stairs to the house

Modular designs are so popular not only because they save a lot of space, but also because they can come in a variety of shapes. The shape of modular stairs varies depending on the assembly method. There are three main configuration options for this type of staircase.

The shape of the stairs is chosen depending on the style of the interior and the amount of free space in the room. It is also necessary to take into account the advantages and disadvantages of all types of structures.

The most popular forms of modular stairs:

1. Marching the ladder is the easiest option to assemble. It is convenient to climb along it, however, due to support pillars, the free space under it turns into a “dead” zone. However, despite the bulkiness of such structures, flight stairs are very popular. The fact is that they have wide steps and a minimum length, so moving along them does not cause any particular difficulties. Such designs are relevant if the height from the floor of the first floor to the ceiling of the fourth is no more than 4 meters.
2. Screw, they are also curved, modular stairs take up minimal space and look very original. However, such marvelous structures have one significant drawback - they are inconvenient to move around. The fact is that spiral staircases have a large number of narrow steps.
3. Rotary the staircase is best option for any apartment. They have wide steps and an original appearance. Moreover, such structures occupy a minimum of free space.

Types of modular stairs can be very different. Only a pre-compiled design project will help you choose the ideal option for yourself.

L-shaped modular stairs

L-shaped staircases made of modules occupy a minimum of space. Such designs look compact and interesting.

Excellent options for modular stairs are provided by companies such as Castorama and Stamet. Also pay attention to the Graz, Superprestige and Stairbox models.

Corner stairs can have a turning platform or winder steps. The first option is the most popular, but the second one looks more unusual.

Advantages of L-shaped stairs:

1. The corner staircase does not take up much space, so its installation is possible in any room. This design will fit both in a two-level apartment and in a private house. If you wish, you can place a sofa or shoe rack under the stairs itself.
2. The relatively low price and simple installation make this design attractive to a wide range of people.
3. The design of corner stairs is combined with all interior styles. By changing the finish of the steps you can transform a classic design into a high-tech staircase.
4. Corner stairs with a turning platform are convenient because if you are carrying heavy objects, you can stop and rest in the middle of the climb.

Modular staircase with 180 degree rotation

Turning stairs can have a variety of configurations. One of the most popular options is the U-shaped design with a 180-degree rotation.

Such designs have the most positive reviews from private home owners. Regardless of whether wooden or metal steps installed on them, such reliable structures will serve you for many years.

Such designs do not take up much space. you can buy ready-made kits or make calculations using special programs and files with the qsd extension.

The advantage of U-shaped modular stairs is that their assembly does not take much time. These designs have an excellent appearance, they are also very comfortable and reliable.

Installation of a modular staircase

You can assemble a modular staircase in a short period of time. The main thing is to understand what type of structural elements you have and how the manufacturer recommends installing them. The assembly instructions for each type of module are completely different.

General sequence of assembly of modular stairs:

• The approach to the upper floor is calculated;
• The support pillars are leveled and attached to the floor with anchor bolts;
• The modular frame is assembled from top to bottom;
• Next, steps are mounted on the frame, which are secured with bolts and metal intermediate elements;
• The intermediate elements are connected to the posts under the railings;
• The last to be installed are railings and various decorative elements.

As you can see, the assembly of modular stairs is not particularly difficult. All the work will only take you a couple of days, and therefore you can easily install such a structure with your own hands.

Due to the popularity of modular stairs, their production occupies a significant niche in construction industry. There are a lot of domestic and imported companies that are ready to provide you with the most unexpected options for such designs.

Assembling a modular staircase (video)

Modular stairs are distinguished by their original appearance and ease of assembly. If you want to create an interesting rise to the second floor without taking up a lot of space, then such designs are the ideal option for you!

Examples of modular stairs (photo)

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 both in a private house and in 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 above, 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.
