Such structures can be wooden, but it is permissible to use metal in the frame, and it is also possible to choose a different angle of rotation of the steps. Projects of staircases leading to the second floor, namely a run-in type, include such a feature as the fact that the structures are arranged in a circular type and are located almost continuously from bottom to top.

Naturally, the upper part of the structure is much smaller in width than the lower one. In this way, it is possible to replace the staircase due to the steps, and save space.

Winder stairs are of two types:

1. Swivel at an angle of 90 degrees.
2. Swivel, in which the angles are 180 degrees.

It is quite possible to do it yourself, both the design and installation of such an interior item, but first you should familiarize yourself with the advantages and disadvantages so as not to be disappointed in the future.

Among the advantages are:

• The ability to reduce the area that is taken away under the stairs, making it more compact;
• A visual increase in the space of the room, which is required even for large-sized cottages, because there is never a lot of space;
• Attractive appearance.

Among the shortcomings, experts note:

• Psychological discomfort that may appear when climbing a tapering staircase;
• The complexity of installation, as well as calculations;
• Lack of comfort, but this is a personal matter for each person, since some prefer to equip stairs with a platform, and others without;
• There is a risk of injury during descent if the structure was installed incorrectly, without observing norms and standards.

Calculation and drawing of a staircase with winder steps

To avoid unpleasant and extraordinary moments after installing a staircase with winder steps, it is worth paying attention not only to their types, but also to how the calculations should be carried out.

It is this stage that is considered especially important, and it should be carried out as carefully as possible. The calculation is carried out when a drawing is created, both in section and integral.

When calculating the dimensions, you need to go through such steps as:

• Calculating the depth along the outer edge of each step, which should not be more than 40 cm;
• Calculation of the average depth of each step, which is generally 20 cm;
• The choice of the height of the steps, which can vary between 12-22 cm;
• The choice of the maximum protrusion from the end part of the treads, which does not exceed 4 cm.

Basically, the most popular staircase is L-shaped. It is easier to draw and easy to install.

To determine the size of such an item in the interior, you also need to take into account all the nuances:

1. To increase comfort, you need to subtract their height (D) from the depth of the steps (C). Basically, it is 12 cm.
2. To ensure maximum safety, the amount of C + D is needed, which is on average 46 cm.
3. To calculate the optimal step, you need to add 2D + S, and this is about 62 cm.

Stair step angles and construction standards

The manufacture and installation of stairs, both with a rotary view and ordinary ones, is carried out exclusively in accordance with the standards of GOST and SNiP, which you need to familiarize yourself with first.

There are special recommendations for a staircase with winder steps:

1. The maximum depth of the steps in the place where they adjoin the wall is 40 cm.
2. The minimum depth of the steps where installation is carried out to the central frame is 10 cm.
3. The minimum permissible depth in the central part of the winder steps should not be less than 20 cm.
4. In height, the steps should not exceed 12-22 cm.
5. The treads should not be overhanging by more than 4 cm.

If the turn of the stairs is 180 degrees, then there should be a special gap between the upper and lower flights of no more than a quarter of the distance between the left and right edges of the treads. In height, ceilings should not exceed a height of 2 m.

Convenient L-shaped ladder

Winder stair constructions and their features

The essence of the staircase, in which the run-in steps, is to exclude the site from the design.

And:

• Replace it on the steps;
• Make the piece of furniture more compact;
• Add comfort and convenience.

This is how they save space in private houses, and it is possible to equip even the smallest in size Living spaces... Experts do not recommend making steps at a depth of more than 40 cm. The closer the step is to the wall, the closer it will be to the central supporting part. Thus, it is possible to increase the radius of curvature of the steps, as well as save space.

With a tread depth of more than 40 cm, the depth of the central frame increases, and thus the structure becomes less secure, which is strictly prohibited. This can cause the steps to break out altogether. emergencies with consequences in the form of trauma.

Winder stairs with 90 degree steps

Today you can find ready-made corner stairs, and of various types, types and heights.

There are two popular types of slewing rings:

• With a spread of 90 ᵒ;
• With a 180 ᵒ turn.

It is worth noting that when calculating the dimensions of the structure yourself, problems may arise with stairs that have a 90-degree turn. The form of seizures cannot be taken arbitrary, you need to adhere to clear standards.

In this case, the product will be durable and safe, and it will also be possible to use the object as conveniently as possible and not worry about the consequences, which allows you to keep all the features and necessary standards.

Keeping track of how wide each element of the staircase has, you can exclude the assumption of problems and oversights. The increase in width from a narrow tread to a wide one should be carried out smoothly and without sudden changes. It is worth noting that the width of the horizontal surface on the largest of the steps should not be equal to the small staircase and should be at least 10 cm more.

A staircase with a landing is one of the most convenient staircase structures. We will tell you about the advantages of such a ladder in the material:.

Winder staircase with 180 degree turn

It is important to remember that if there are no specific skills for installing stair structures, then it is advisable to choose the services of professional craftsmen in order to be 100% sure of safety and strength.

The main requirements for swivel stairs with an angle of up to 180 degrees are:

• Compliance with the width of the turning steps along the edge of at least 40 cm;
• Compliance with the width of the turning step in the middle of at least 20 cm;
• Compliance with a turning radius of 30 cm.

Execution of all stages, including turning ones, along one line.

DIY staircase with winder steps (video)

Thanks to this, the staircase will look stylish, fashionable and, most importantly, comfortable. When purchasing stairs of a ready-made plan in a store, you need to clearly check the presence of all the necessary components and fasteners when assembling and installing.

Winder staircase design (photo in the interior)

Even a one-story object is not devoid of steps inside - there are stairs to the attic or low, often found structures in the interior, crowning the design idea. A house in several tiers needs to be lifted especially, and the ease of use and safety of the household depends on what type of stairs the owner chooses for self-construction. The most common option is a do-it-yourself staircase to the second floor made of wood with a 90-degree turn.

Types of rotary wooden stairs

As a rule, these are L- or U-shaped two-march models. The swing angle is 90 and 180, respectively.

In addition, stairs are divided into the following options:

Additional advantages of both options are convenience and safety. The structures are calculated in such a way that they can withstand the weight of the cargo transferred to the second floor and a sufficient number of assistants. The width and depth of the steps will allow the elderly and small children to use the stairs without fear for their safe movement.

Designing a swing ladder with a 90 degree angle

Small houses for a small family do not need wide and bulky spans. Therefore, we will consider the design of a 90 ° corner staircase with winders instead of a transitional platform. It will take up little space, since it has only one march, several steps act as the second. It is best to position the structure with a clockwise rotation.

Tools and materials

The choice of wood must be approached carefully.

First, why wood? Because only this raw material lends itself to self-adjustment and design - in the process, you can make mistakes with calculations and correct inconsistencies very easily.

Secondly, it is a budget option building material.

Thirdly, wooden houses require similar ladders - steel or concrete are incompatible.

As for the breed, it is important to choose hard varieties - beech, oak, larch.

A budget pine is allowed, only it is important to ensure that there are no inclusions of knots in the boards and beams, which the breed is very sinful with. The residential building is notable for its violent activity - moisture, temperature extremes, dry air. From this, the staircase will begin to deform to one degree or another and the knots will fall out of their places, creating dangerous situation to operate the product. Before the manufacture of parts, all wood is dried and impregnated with moisture-repellent and protective compounds against biological damage - mold, bugs.

The required tools are known to every carpenter:

• hacksaw;
• electric jigsaw - it will help to gently round the edges;
• screwdriver;
• hammer or mallet;
• bit;
• square;
• level.

To design parts, choose:

• support bar with a section of 100 mm and more (depending on the height);
• edged board 50 mm thick;
• auxiliary bar with a section of 40 mm;
• fasteners: self-tapping screws, steel corners, anchors, screws, bolts;
• wood glue or epoxy.

Components should not cause any complaints. It is better to select fasteners in anti-corrosion design - the temperature difference between the building materials will create conditions for the formation of condensation, which is detrimental to both metal and wood.

Calculation of stairs to the second floor made of wood with a turn of 90 degrees

Before starting work, it is required to prepare a drawing, where all the components of the structure are scrupulously marked. To do this, use calculation formulas or computer programs.

To draw up an accurate verified project of a staircase with a turn of 90, it is important to know the following values:

• March width. It is important to proceed from your own wishes, however, it should not be less than 80 mm.
• The length of the projection of the staircase from the last upper riser to the corner of the central winder.
• Step width. Minimum 120 mm.
• Step height. Maximum 220 mm.

The calculation for the real dimensions of the winders is carried out on graph paper. For this, two rectangles are drawn, depicting marches with known parameters converted to scale values, with a line passing through their centers. They are connected by a circular arc through which the radius of the central winder will pass. From it, the elements are laid out, keeping an eye on the optimal and uniform width.

Example: a two-flight staircase with a long and short span of 8 and 2 steps, respectively. Zabezhnye steps in the amount of three pieces are located at an angle of 30?. The structure has the following parameters: opening length - 2294 mm, width - 930 mm, height to overlap - 2683 mm. The length of the steps is 825 mm, the width is 208 mm, the height of the riser is 206 mm. It remains to designate the real dimensions of each part on paper and you can start cutting.

Sawing of stringers

For the load-bearing parts of the stairs, a template is made - a right-angled triangle with the dimensions of the step depth and the riser height applied. It is cut from plywood or used with a square. Markings are applied with a pencil, they are checked with the rule - the thin part of the board width is not more than 15 cm - and the excess is cut out.

It is better to use a jigsaw - it will neatly cut the pieces along the marked lines. The ends of the prepared boards are immediately sanded so as not to let them go with chips.

Installation of support pillars

To fix the stringers, a support bar of 100 mm is attached. The place of its installation is determined by the drawing. Most likely, it is located diagonally opposite the corner of the room. The bar is fastened with steel corners, anchor bolts or concreted into the floor - depending on the stage of construction of the house. In addition to a thick support, a bar with a cross section of up to 50 mm is used. Supports for the wall stringer and the base for laying the winder steps are made from it.

Fastening the stringers

Work begins from the top, so that all the shortcomings fall on the bottom, where it will be incomparably easier to fix them. The stringers are attached to the ceiling using steel corners, bolts or self-tapping screws. The lower part must be inserted into the support bar. To do this, a groove is hollowed out or cut out on it. Its dimensions are 2 cm deep, and the width and length are 1 mm less than the end. This is necessary in order for the stringer to enter tightly. For reliable fixation, a paste is prepared from sawdust and wood glue. It is put inside and knocked out with a mallet kosour.

The wall element is fixed similarly at the top, and from the bottom it is fixed on a metal corner to a support of a smaller section, having previously cut out the end for laying the winder. All work is carried out with the indispensable observance of the level, otherwise the future steps will not lie parallel to the floor.

Making steps for stairs

Steps for marches are cut out according to the template. These are the same elements and there shouldn't be any difficulties. Installation and winder steps are not difficult. For them, a separate platform is purchased from boards or multilayer plywood and the steps are cut according to the drawing - the lines go out from one corner. When all the elements are prepared, they are treated with protective compounds and varnished in several layers.

Assembling stairs to the second floor with a turn

In contrast to the fastenings of the supports, the temporary fixation of the steps is carried out from below - subsequently, after adjusting all the parts, the structure is disassembled and, after processing, is laid again. A bowstring is made for the lower march - a board according to the kosour principle, but without coal cuts for laying steps. In the inner part of the wooden element, grooves are knocked out or cut out, where the steps will be inserted.

A wall short bowstring is made in the same way as described above. The upper end of the outer string must reliably hide the end of the winder, and the lower end is cut perpendicular to the floor for the subsequent installation of the riser. Having installed the first straight elements on self-tapping screws with outside and glue paste from the inside, proceed to laying the radius. They are fixed in the same way. Straight steps are laid, sawing grooves at the ends for inserting into a stringer. Before fixing to fasteners, all elements are glued.

The risers also lead to the bottom. Inexperienced craftsmen make the mistake of making blanks equal to the tight fit between the steps. This is not necessary - the house will live a rich life, where moisture and steam are present. Swelling, the elements can break the entire structure, or at least deform it. A 5 mm gap is enough to keep the ladder model strong for many years.

Fences and balusters

Decorative elements of the staircase - railings and balusters - play a significant role in the interior. They are bought ready-made. But if the master has golden hands, nothing prevents them from making them on their own.

Special attitude to fastening: it is required to place balusters often - on each step. This will create additional support and safety for children and elderly home owners. Plus it's beautiful.

It is impossible to fasten the balusters to the steps with self-tapping screws - it is not reliable. It is better to use dowels - small wooden rods like dowels. For them, holes are specially drilled at the edges of the steps, which should be less than the rod by a couple of millimeters. Before inserting the dowel, the hole is filled with glue or epoxy.

Holes are also drilled in the balusters themselves, moistened with a fixing compound and the elements are put on wooden rods. The structure is carefully hammered with a mallet for better adhesion.

A cord or fishing line is pulled over the top baluster and the support post. It is pre-blackened to make accurate marks on all decorative elements. All unnecessary upper parts are cut off, observing the parallel with the stringer - so, the fence will lie flat. The handrail is either put on the balusters and screwed with self-tapping screws from below, or fixed from above, but then the fasteners will have to be putty.

The finished staircase should be passed from top to bottom grinder or with sandpaper and remove fine dust. Then they decide what kind of design decorative compositions required - usually, wooden surfaces are varnished, stained or painted if the quality of the material is not the best.

How to care for a wooden staircase

Wood is the most moody construction material and without proper care, the staircase will not serve its owners for a measured period.

What you need to know for the operation of the turning ladder to be reliable and long-term:

• Do not expose the structure to excessive moisture. Cleaning consists in wiping wooden surfaces with a damp cloth without using aggressive detergents- alkalis, solvents, acids. The final step in cleaning is to wipe the surfaces dry with a special furniture wax.
• It is important to create a ventilation balance in the house, since overdrying for wood is fraught with cracking and creating cracks for breeding centers of mold and bark beetle larvae. In inconspicuous dark places, they breed with catastrophic speed.
• Eliminate all problems in a timely manner - gluing joints, unscrewing fasteners, loss of stiffness of steps and fences, creaking. Prevention is primarily important for the safety of the owners. If required, the structure is disassembled or defective elements are replaced.

It is important to remember that the finished staircase will shrink, like any wood product. Therefore, it is not recommended to carry out self-assembly tightly at once - for 2-3 weeks the staircase should be assembled "on a jig".

Simple methods of preserving the original appearance of a wooden rotary staircase will allow home master to be proud of their own product for a long time. However, any ladder is a consumable item. home interior and over time it will require replacement. This is important to remember if the owners are going to make a model from valuable rocks.

Calculation of stairs with 90 ° turning steps.

A wooden staircase with swivel steps allows you to significantly save space in the house without losing convenience and functionality. When calculating, pay attention to the optimal number of turning steps. In my experience, 3 steps are optimal with a staircase width of 80 cm. More - the steps will be too narrow and therefore uncomfortable.

If the opening is located only above the top of the stairs, then the height at the turn to the overlap is important to avoid head injuries. It must be at least 2 meters long.

With this design, the width of the staircase plays important role... Since it directly affects the convenience of the turning steps. The wider the staircase, the more steps it is possible to use without losing convenience.

Due to the variety of projects and structures, railings for stairs in the program are not calculated or shown in any way.

Important! Pay attention to the dimensions of the turning steps. To get the dimensions of the step, do not forget to add the size of the protrusion to these dimensions.

Calculation of a stone staircase for is no different from the calculation of a wooden or metal staircase. The main thing is to correctly calculate the size of the steps. Their height must necessarily be the same for all its parts.

The stairs comfort calculation is calculated using a formula based on the step length.
The stride length of a person is from 60 to 66 cm, on average - 63 cm.
A comfortable ladder corresponds to the formula: 2 step heights + step depth = 63 ± 3 cm.

The most convenient stair tilt is from 30 ° to 40 °.
The depth of the steps of the stairs must correspond to shoe size 45 - not less than 28-30 cm.
The lack of depth can be compensated for by the step protrusion.
The step height should be up to 20-25 cm.

The program draws drawings of a stair with turning steps with basic angles and dimensions.
The drawings show overall dimensions stairs, marking of the top of the steps on the bowstrings, the angles of the steps and the main dimensions of the steps themselves.

I hope the program will help you design and make a staircase for a summer residence or at home with your own hands.

If you do not know the initial data that are necessary for calculating a 90 ° rotary staircase, you should read the next paragraph, which presents the optimal dimensions of structural elements in private houses. Recommended reading.

We warn you that for the construction of stairs there are certain building codes and regulations governing the methods of calculating loads and strengths, dimensions, quality of materials, etc. It is necessary to design a staircase only in accordance with these rules, which include various SNIPs and GOSTs, in order to avoid the collapse of the structure, or its increased injury risk.

Calculating a staircase online with a 90 ° turn with a platform on our website allows you to avoid most of the difficulties. Possible mistakes will be highlighted in red in the block "Calculation results".

For the calculation of wooden staircases, whole "convenience formulas" have been derived. In construction practice, the most commonly used parameters for comfortable, durable and safe stairs have been formed. For example, most craftsmen use the well-known formula of the "ideal safe staircase", which was deduced several centuries ago by the architect Francois Blondel:

Comfortable ladder formula: 2 × h + s = 60/65 cm

• h is the height of the steps;
• s is the length of the steps.

• Stair tilt angle... Convenient tilt angle wooden stairs between 30-45 degrees.
• Stair width... Per optimal size the width of the span of one march in a private house is taken 90-110 cm, with insufficient space in a private house, the staircase can be made narrower, but not less than 80 cm.
• Height and width of steps... According to practice, the ideal step height is in the range of 15-17 cm, the optimal step width is 27-30 cm.
• Thickness of steps, risers and stringers... Elements are made from wooden planks, for a riser with a thickness of about 3 cm, and for steps - 4 cm, kosour - 5-7 cm.
• Minimum overhang. The minimum step overhang above the riser is 30 mm, the maximum for a wooden staircase is 40 mm.
• Number of steps... The maximum number for one flight of stairs is 18 pieces. On average, it is recommended to use 10-12 pieces.
• Fencing... For safety reasons, the height of the railing should be higher than 90 cm.

3 requirements for the calculation and installation of stairs with a turn of 90 degrees

Various ladders with a turn of 90 degrees are fairly compact designs. Sometimes they are supplemented with special intermediate platforms. Although some craftsmen prefer to use winder steps in order to save space. Yes, it is quite possible to make such structures with your own hands. But this is an extremely complex process that requires accurate calculations.

Swivel staircases with winder steps are a kind of intermediate option between straight structures and more complex, spiral structures

Standard Requirements for Swing Ladders

The detailed instructions for calculating and installing the structure, posted in this article, will help you create not just a beautiful, but a truly reliable staircase that will serve its owners for many years. However, before starting to manufacture it, you should familiarize yourself with the basic requirements for structures of such a plan:

• the height of the staircase must be at least 2 m;
• the length of the steps of the products should range from 80 to 110 cm;
• the width of the steps (on a straight march) cannot exceed the mark of 37 cm.

The minimum step width for a pivoting structure is most often exactly 35 cm

But the height of the steps should reach 17 cm. Its increase will significantly increase the load when climbing the stairs, the photo of which is below. In addition, during the descent, these elements may well become traumatic. Separately, it is worth mentioning the width of the winders. In the middle part, it cannot be less than 20 cm, and in the narrowest - less than 10 cm, this is really important.

The height of steps on a straight flight cannot be less than 14 cm under no circumstances

After watching all sorts of videos about stairs posted on various network resources, you can understand that the aforementioned structure is considered not only extremely convenient, but also incredibly functional. However, during its manufacture, it is necessary to take into account a lot of nuances. One of them is the optimal number of turning steps. For a structure with a width of 80 cm, it is recommended to use three such elements, no more.

An increase in the number of turning steps sometimes extremely negatively affects the level of convenience of a staircase

You should also pay attention to the dimensions of these steps. When calculating their dimensions, you must also take into account the size of the available protrusion. But the height of these parts should be the same in all parts of the structure being created.

The comfort of a 90 degree staircase is always calculated using a special formula based on the length of a person's steps. On average, it is 63 cm.Therefore, indeed convenient structure corresponds to the following formula: 2 full step heights + optimal step depth = 63 ± 3 cm.

It is desirable that the slope finished product did not exceed the mark of 40 degrees. The depth of the steps of the structure should range from 28 to 30 cm, but their height must be exactly 17 cm. Such calculation and installation instructions will allow you to create the required rotary product in a relatively short time.

The overall width of the structure is also very important. It directly affects the convenience of the applied turning steps.

Competent manufacturing of staircase structures: selection of suitable materials

In order to make a high-quality staircase with your own hands, you will need to choose for it good materials... Basically, rotary structures are made exclusively from wood such as:

Beech. It is recommended for use in rooms with high humidity.

Beech stairs always look incredibly attractive and graceful. That's why they became so popular Maple. This material has excellent resistance to various external influences, but small cracks often appear on it.

Maple wood has sufficient flexural strength, this must also be taken into account. Larch. This wood is extremely durable and tough.

Larch is very resistant to decay. And in terms of strength, it is slightly inferior only to Oak Oak. This material is also considered incredibly durable. However, it is quite heavy, therefore such a nuance must be taken into account when working.

Oak stairs are very beautiful and reliable. But they are also more expensive than their counterparts.

In some cases, staircase structures, photos of which are posted in the article, are also created from pine. But it should be carefully checked for knots. Indeed, under the influence of high temperatures, the structure can deform. If the existing knots fall out, the structure will weaken significantly.

Yes, pine structures are far from the most durable. But their main advantage is considered to be quite acceptable cost.

What tools will need to be prepared in advance?

From the video about the manufacture of swivel stairs, you can find out that to create products of this type, you must definitely stock up on certain tools:

• professional screwdriver;
• drill and drills;
• jigsaw;
• perforator;
• a good hacksaw for wood;
• chisel;
• file;
• with an ax;
• hammer;
• gas wrench;
• convenient side cutters;
• squares;
• ruler;
• level.

When working with a jigsaw, be sure to use special protective goggles and gloves.

In addition, the craftsmen should prepare several load-bearing bars with a section of 100x100 mm. However, it can be large. It all depends on the specific height of the march of the future structure. To create a staircase with a 90 degree turn, you need to use an edged board, the thickness of which is exactly 50 mm. It is also advisable to stock up on wood glue, special screws, anchor bolts, screws and corners.

Among other things, you need to purchase attractive balusters and handrails in advance. They will make the stairs more original.

Step-by-step installation of a robust design

The detailed instructions for calculating and installing a staircase, which are in the article, will allow you to easily make an aesthetically attractive product that will fit into any interior. To create high-quality construction with their own hands, the masters will have to:

1. Make a template as right triangle. It is desirable that his legs are equal to the height of the riser and the depth of the tread.
2. Fasten the triangle securely directly to the guide rail.
3. Mark out the stringers with a template and cut off the excess.

In the thinnest part, the width of the finished stringer should not be less than 15 cm

Install the support pillars, having previously hollowed out the grooves for the stringers in them.

Secure the upper ends of the elements using the prepared corners.

During the installation of stringers, you must very carefully monitor the level. Due to this, the staircase steps in the future will lie strictly horizontally.

Cut out the run-in steps from a rectangular board, adjusting them along the length.

Apply at least three coats of glue to the steps.

Cut grooves for steps in the posts.

For the winder steps, a board with dimensions of 900x900x40 mm must be used. And the height of the grooves intended for fixing these elements should be less than the thickness of the board

Modify the support structure from the outside.

Fasten the straight steps with longer screws.

Make the bottom flight of stairs on the bowstring.

Cut the end of the string exclusively at right angles.

At the end, balusters are usually installed, this is clearly visible in the photo. First, the craftsmen drill small holes in the steps and carefully fill them with glue. And then they make exactly the same holes in the balusters themselves (in the center). Dowels are used to secure the elements.

In principle, it is allowed to fix the balusters with self-tapping screws. But this method is considered less reliable.

Then the rope is pulled between the first and the last pillar. It notes optimal angle tilt of the railing. To prepare the balusters for installing the handrails, it is enough to carefully cut off the tops of the posts. And the railings are already attached with self-tapping screws. In general, the process of making a swing ladder is perfectly described in this video.

The optimal combination of price and quality!

Of course, it is quite possible to create stairs with a turn of 90 degrees on your own. But it is much easier to purchase ready-made structures with the help of our specialists in Moscow at the lowest prices.

This ladder comes standard with a metal frame, one side railing and uncoated pine steps

Do-it-yourself stairs to the second floor made of wood with a turn of 90 degrees: calculation and installation

For the manufacture of stairs, many modern materials... Nevertheless, wooden staircases in the interior of the house are the standard of impeccable style. It is the wooden structures that create the feeling of home comfort. The key points in the arrangement of the stairs are accurate calculation, quality workmanship and correct installation. A staircase to the second floor with your own hands made of wood with a turn of 90 degrees can be installed due to strict adherence to the recommendations for the design and calculation of the structure. It will save useful space and provide free and comfortable movement on it.

Accurate calculation of a wooden staircase greatly simplifies its installation, guarantees convenience and a long service life

Types of stairs to the second floor. Photo of design of different models

Before equipping your house with a staircase, it is necessary to determine exactly what type of staircase will be and from what material. The choice of the type of staircase system depends on its location in the room, the layout of the house and the individual preferences of the owner. The materials for their manufacture, given the rapid growth of technologies, can be a variety of samples: plexiglass and ceramics, a natural stone and marble, metal and wood.

Marching stairs are the most popular way of arranging stairs

The main types of stairs are classified according to the type of the supporting element:

• marching stairs - on stringers or bowstrings;
• spiral staircases - with a support in the form of a bearing rack;
• ladders on the bolts - no-frame systems. The steps of such a staircase are attached to the wall, and are connected to each other with the help of bolts;
• combined - when one system includes several types of structures.

L-shaped marching rotary staircase with platform

The main difference between the stringer structure is that the steps are fixed on top of the supporting element. While in bowstring systems there are recesses, where steps are inserted. Marching systems, in turn, can consist of several flights, interconnected by a platform or winders.

The choice of one or another marching system depends on the location of the stairs in the room and the availability of the necessary space for its installation. In the case where space is limited, rotary systems of flight stairs are used. To connect different levels in private cottages, stairs made of wood are most often used. Such designs are quite lightweight, fit well into various interiors and can be made by yourself.

Flight staircase with a turn of 180 degrees

Numerous photos of wooden stairs to the second floor with their own hands confirm the popularity of the use of this material for stair structures.

The ladders on the bolts do not have a frame in their design. Each step of such a staircase with the help of special fasteners rests on the wall on one side, and on the other, is connected in series with bolts. The structures of the stairs on the bolts have an openwork light appearance and are highly durable. Such stairs can be installed along the wall, which will be the supporting element, or in any other place in the room - then a metal profile will act as a supporting structure.

The variety of modern staircase systems in the interior is evidenced by do-it-yourself photos of stairs in the house to the second floor.

Staircase with 90 degree turn with winder steps

Types of rotary flight stairs

Marching staircase systems can be straight and rotary. Straight flights in private houses are used when the dimensions of the rooms are spacious enough to install a long straight span. Most often, wooden rotary systems are used to connect the first and second floors. So, there are wooden stairs to the second floor with a turn of 90 and 180 degrees. They are called L-shaped and U-shaped, respectively.

Marches of L-shaped stairs can be interconnected by platforms, two winder (turning) steps, three turning steps. How more number turning steps, the less convenient it will be to move along them. Structures of stairs, installed in the corner and having a fence, include in their design an angular (support) post, on which run-in steps, balusters and a bowstring are attached. The corner post is installed on the base or can be suspended.

Stair designs with 90 degree turn

U-shaped staircase systems are constructively solved through a turntable or run-in steps. When arranging a U-shaped staircase important point is that the railing of the stairs in the upper projection should not intersect, therefore it is important to correctly calculate the stairs to the second floor. In both U-shaped and L-shaped rotary staircases, the use of run-in steps allows you to maximize room space savings.

The space left under pivoting stairs is often used to advantage for storage rooms or cupboards. Some photos of stairs to the second floor in a private house with their own hands clearly demonstrate this.

Do-it-yourself stairs to the second floor made of wood with a turn of 90 degrees: we design ourselves

Many manufacturers today offer ready-made sets of elements for staircase systems. To order such stairs to the second floor, you will need to make clear measurements of the span height, determine the estimated width and length of the stairs and transfer the data to the selling company. However, this method will deprive you of the pleasure of making a staircase structure yourself, endowing it with individuality and originality.

DIY materials and tools for making wooden stairs to the second floor

The use of wood in construction, including for the manufacture of staircase structures, is due to its high strength characteristics, environmental friendliness, ease of processing and a relatively affordable price.

The width of the stairs is selected based on the convenience of movement and the availability of free space

The staircase to the second floor with your own hands made of wood with a turn of 90 degrees can be made of the following hardwoods:

• beech - used for rooms where high humidity is not observed;
• maple - its wood is very stable, has sufficient bending strength. However, it should be borne in mind that maple is prone to cracking;
• oak is an excellent building material. It has strength, hardness, rather heavy material;
• larch is a decay-resistant, hard and durable wood. In terms of hardness, this breed is second only to oak.

Marching rotary ladders are easy to move and reliable in operation

Sometimes pine is used for stairs, but you should check the wood for knots. Under the influence temperature regime deformation of the staircase is possible, as a result of which the knots can fall out, and lead to a weakening of the structure.

When starting to manufacture a staircase, the wood must be thoroughly dried and treated with special compounds to make it resistant to moisture, mold and mildew.

Elements of the main staircase with a turn of 90 degrees

To make a staircase made of wood to the second floor, you will need:

• bearing bar 100x100 mm (the section may be large, depending on the height of the flight of stairs);
• edged board with a thickness of 40-50 mm;
• handrails, railings, balusters;
• wood glue for sealing all joining lines and gaps.

For arranging a wooden staircase, choose well-dried and well-processed wood.

A staircase to the second floor with your own hands made of wood with a turn of 90 degrees can be made and mounted using the following tools:

• a hacksaw for wood, a set of drills, a chisel, a file;
• screwdriver, hammer drill, drill, jigsaw;

Helpful advice! When working with a power tool, follow the safety rules: use protective equipment (goggles, gloves), do not hold the cord of a working tool, watch the position of the wire to avoid damaging it, do not use the tool near open flames.

• ax, hammer;
• square, ruler, level;
• gas wrench, side cutters (side cutters);
• hardware: self-tapping screws, screws, anchors, corners.

It is convenient to cut with a hacksaw on wood wooden parts stairs

Features of calculations of a 90-degree rotary staircase

For the correct calculation and design of a marching rotary staircase, you should familiarize yourself with some of the features of such structures.

The main elements in them are:

• bearing beams - these can be stringer or bowstring beams;
• steps - in rotary staircases these are straight steps and rotary (run-in) ones, with the help of which the rotation of the structure is realized;
• stair railings - includes balusters, railings and handrails.

Prefabricated wooden balusters in a variety of colors and shapes

The calculation of rotary stairs is carried out using:

• geometric formulas;
• graphic methods - here you need to determine the middle line of the span (march). In a curved structure, this line runs parallel to the inner edge of the structure at a distance corresponding to the middle of the step width. The radius of curvature of the turning step depends on the radius of the circle between the two spans.
• You can use an online calculator to calculate, where you enter basic data: the length and width of the opening, the height of the steps, the thickness of the stringer and the protrusion of the steps.

The choice and calculation of the staircase marching structure is determined by the width of the opening and the height of the room

Calculation of a staircase made of wood to the second floor with your own hands: drawings, diagrams, tables

When calculating a staircase made of wood to the second floor with your own hands with a turn of 90 degrees, you should decide in what way the turn will be ensured: by means of an intermarch platform or turning (winder) steps. Considering that the stairs with the platform are installed in a fairly spacious houses, we will give as an example a rotary staircase with run-in steps.

The dimensions of the stairs are selected individually, but it is worth adhering to certain recommended parameters:

90 degrees

Typically 90 ° swing stairs are popular with people who have limited space in their home. This type of construction significantly saves space, while being compact. They are often installed in the corner, and under the steps, the owners organize pantries, putting useful inventory and various little things there. The advantages of such structures are also an affordable price, a large number of configurations and versatility. Thanks to the latter, they look great in any interior.

If indoors high ceilings, then it is also worth paying attention to the buildings from a series of steps with a 90-degree turn. To make the ascent safer, it is preferable to use an intermediate platform during the construction of structures.

Let's voice some of the features:

• the space under the steps can be used for your own needs;
• can, if necessary, have an approach from any side: stairs at ninety degrees right-handed and left-handed;
• run-in steps during the construction of a structure are less in height than other types of stairs;
• marches are at right angles, the intermediate platform is executed in the form of a square.

The most commonly used material in the manufacture is wood. In the production of 90 degree rotary wooden stairs, hard woods are used: oak, ash, beech. Or semi-solid: spruce, larch, pine. Wooden structures have always been famous for their grace. Plus, wood products will have a beneficial effect on health.

The presented structure, right-handed or left-handed, can be equipped with winders. Climbing a winder staircase with a 90-degree turn cannot be called very comfortable, since inner side there are fewer steps than the outer one. However, the design has a sleek look, and if properly positioned, it will save a lot of space and will last for many years.

Calculation of a rotary staircase at ninety degrees

Calculating the dimensions of the finished structure is not an easy task. You can use special mathematical formulas, but it's easier to do this with the help of an online miscalculation calculator, which can be found on the Internet. You will need the following measurements:

• the distance between two floors (from the floor of the first floor to the floor of the second);
• opening length;
• the width of the structure.

This is the minimum set of parameters that you will need.
With certain knowledge and skills, you can carry out the calculation yourself. If not, then we recommend using the services of our professional measurer.
