Staircase device in a private house - features, do-it-yourself manufacturing + Photo and Video

Staircase in a private house - features, manufacturing. Nowadays, private construction is so widespread that the construction of a structure with several floors in its summer cottage can already surprise few people. In this regard, there is an urgent need to make a staircase in a private house with your own hands, the device of which can be anything to ensure the connection between the floors. In addition, in the article you will find useful videos that will help you understand this topic even better.

Varieties of stairs, materials of manufacture and arrangement rules

To begin with, it should be noted that only several types of stairs are used in private houses, and among them we note two main species - stringer and non-stringer designs, but they also have their own subspecies.

Also, the difference lies in the number of stages and their device, but the general manufacturing requirements still remain unchanged.

Ladders on bowstrings and stringers

Construction on bowstrings made of metal:

• First, let's consider what is the difference between a stringer and a bowstring, since they are often confused with each other, although this is not of fundamental importance. So, kosour is an inclined beam with a comb on top, which is needed to hold the steps or the total reinforced concrete march. But unlike him, the bowstring is an inclined beam, which is used in pairs, but the steps in this case are not located on top, but between them in special grooves, or they are welded using electric welding.

As shown in the diagram, profiles for stringer or bowstring: 1) sawtooth bowstring made of sheet steel.

2) a straight type bowstring made of sheet steel. 3) a section with teeth. 4) channel bowstring. 5) box-type stringer. 6) I-beam stringer.

7) stringer without bracket. stringer with bracket.

• As you can see in the diagram, stringers and bowstrings are made most often from a channel, a flat rectangular / square profile, an I-beam, and also from sheet steel. In addition, almost all types of metal profiles and wood can be used for the comb. In addition, inclined beams can be reinforced concrete and wooden - a lot depends on which type of staircase you choose.

Construction of a metal stringer (I-beam)

• In another diagram, it can be seen that the kosour is made of an I-beam, which can be used both in the singular, in the role of an inclined central beam, and in pairs, when the steps are laid on them with their edges. You see a device with the implementation of all the principles that the instructions require, and 1) a channel, an I-beam or a flat profile. 2) wood / metal treads. 3) structural consoles for fixing risers and treads. 4) attachment of consoles by bolting or welding.

  5) installation of treads using bolts or welding.

A staircase made of wood on metal braids (with wooden sheathing)

• When such a staircase is created in a private house, a metal braid is most often made , and then they perform wooden cladding, due to which the fastening is practically invisible. Of course, such structures used to be made entirely of wood, namely from beech, oak, spruce, ash, hornbeam, pine, but these materials very quickly deteriorate and cannot be partially repaired, on the contrary, the entire structure will have to be replaced, which is inconvenient and expensive ...

  If you make a metal base, then this structure will be subject to reconstruction, and it will be much easier to replace individual worn-out elements.

• You can also create a staircase in a house on one central stringer, and it is also most often made of metals according to the same principle as described above. The beam itself can be attached to the floor of the upper and lower floors, but in such cases, additional supports made of concrete, wood, and even more often, their metal pipes are used for props.

Bezkosourny stairs

Spiral (spiral) staircase

• If there is a lack of free space in the living area, such structures are used quite often, namely spiral or spiral staircases. The only difference is that for structures of a spiral type, the base is only a central support post, which, as a rule, is made of a metal pipe with a diameter of at least 10 cm, and bolts or kosour can also be used for the screw.

• The most problematic place for these structures is the narrow turning part, in which the steps are located almost one above the other, and for this reason there is often not enough tread width here. Because of this, the minimum permissible width of the staircase in this case is 0.6 meters, even if this is the entrance to the attic, which is rarely used.

Good advice! If you are too keenly aware of the lack of space, then to enter the attic, give up the overly narrow spiral staircase and use a retractable folding structure.

Stairs on the bolts

What are the attic stairs?

• bolts themselves) has an inconspicuous fastening system for the steps, which makes it seem soaring, airy.

  It turns out that the steps are held thanks to rubber gaskets with bolts that are inserted into the wall, and the steps are held both on them and on balusters that can be attached to the railing. In modern designs, these projects are unrealistically in demand, since they are light and stylish, and the bonus is that the price of such structures is not so high.

Number of steps

In many ways, the number of steps will depend on the slope:

• As shown practice, the most convenient slope for arranging a staircase is an angle from 30 to 35 degrees and all because with this slope the most comfortable steps are obtained, and climbing them to the top is the most comfortable. According to statistics, if you climb the stairs, the angle of inclination of which is from 40 to 45 degrees, only a well-physically developed and trained person will not feel inconvenience, and this practically cannot be attributed to the elderly. Also very important is the total number of steps and their height / width, which should be equal to the average human step, which ranges from 0.

  6 to 0. 64 meters.

• In order not to get tired of walking on such steps, it did not cause discomfort, and even more so it was not dangerous, the width of the tread should be no less than 70% of the length of a human foot, which is about 26-31 cm. For example , the height of each step will be 18 cm, and the width of the tread will be 38 cm, then 18 * 2 + 28 = 64 cm.This is exactly the value that will be as comfortable and safe as possible.

To create an ideal device for a wooden staircase in a private house with our own hands, we suggest calculating the length of the stringer along the sides of the triangle:

• Imagine that you need to design an interfloor staircase with your own hands, and for this you should use the sides of a triangle with one right angle, and A is the floor level of the lower floor, B is the distance from the second to the first floor, and C is the very length of the stringer that we are looking for, CB is the floor level on the second floor. You can substitute any values, but let's use the following - the distance of the segment A = 5 m, B = 2.7 meters and it remains to find out C.
• To do this, use the school formula a ² + b ² = s ² , and then substitute the numbers and get 5 ² +2.7 ² = s ² , i.

  e. with ² = 25 + 7. 29 = 32. 29. Now it is necessary to extract the square root of the obtained value (32.

  29) and we get ~ 5. 7

• Now, to calculate the width of the tread, divide the number of steps by the estimated protrusion of the bowstring / stringer and take a value, for example, in 20 steps, and then the width of each will be 500/20 = 25, and the height 270/20 = 13 , 5 cm. So, we got an almost normal value, especially considering that the rise is steep, about 45 degrees. If you want to increase the width of the tread, you can use the winders.

Interestingly, a staircase with run-in steps is a current type of construction used in premises where the area does not always allow the installation of a single-flight staircase.

The winch structure is a staircase divided into two flights with a section of a spiral staircase between them. But the minimum distance from the upper edge of the visor to the lower edge in width should be 10 cm, otherwise the design will be dangerous for descent (as the heel will slide off).The protrusion of the visor can be 3-4 cm, but it should not be more than 5 cm so that the sock does not cling to when lifting.

Good advice! In order to ensure safe ascent and descent, it is important which march width you choose. So, the permissible width is considered to be from 0.

7 to 0.8 meters, the usual from 0.9 to 1 meter and comfortable from 1.2 to 1.5 meters, where two people of obese build will freely disperse.

Conclusion

The overall comfort will depend on how you arrange the stairs in a private house, since the message between floors and rooms will be perceived at a subconscious level ... For this reason, so that you do not lose the desire to get into different parts of the house, try to make the stairs as comfortable as possible in your conditions.
