Some people do not want to build a one-story house and are building a multi-storey one, and it will be impossible to move around the house without stairs. Ladders come in a variety of shapes and materials. The stairs that are between the floors are made of wood, metal and concrete.
In the article we will tell about a staircase made of metal, which will be located between the floors. But the properties that metal has make it possible to manufacture stairs of any design and at the same time strong, lightweight, beautiful, even airy stairs.
The construction of a simple staircase to another floor with one flight is not difficult, if you have some skills. But a staircase with several flights is more difficult to make, but you can learn everything, if you wish.
Ladders can be wooden, metal or concrete.
The design and calculations for stairs located between floors from any materials are no different.
They have the usual requirements:
Ladders are of the following types:
There are stairs :
If you do not have special skills in building stairs, then start with a simple option, then there is a single-march design.
In organizations that are engaged in development projects, use special computer programs, with the help of these programs they design 3D models of structures.
In a 3D model, it is very easy to change the parameters of different parts.
After approval of the final version, the computer program prepares the specification and drawings of the metal staircase.
But in our case, the calculations will have to be done without the help of a computer program. We will consider a simple version of a direct one-march construction.
The basic requirements for the depth and height of the steps are already known.
It is necessary to make measurements between the points, that is, from the beginning to the end of the stairs from the floor of the first floor and the height between the floor of the first and second floors. Now we determine the length of the stairs, we must remember that the average angle of inclination is from thirty to forty-five degrees.
To calculate the length of the stairs, you need to remember the geometry, that is, about a right-angled triangle. Indeed, in a right-angled triangle, the square of the hypotenuse is equal to the sum of two squares of the legs.
We calculate the available parameters and extract the square root and get the length of the stairs.
Next, a suitable number of steps must be calculated.
For the construction of an interfloor metal staircase, in order to build an interfloor metal staircase, we need the following tools and materials.
Stages of work:
First of all, angles are made from the corners for fastening the steps, that is filly.
It is impossible to make a mistake so that there are no various distortions and flaws that will ruin the stairs.
In the same way, filly must be the same and must be exactly opposite each other. Fillets are made from a corner by cutting a sample and joining the corners together.
As a result, L-shaped nodes are obtained with shelves down and inward.
For our design, fourteen pairs of these nodes are needed, and in each of the pairs one support will be left, and the second right. Then we weld the brackets to connect the steps and the horizontal bar between each of the pairs of corners.
We also make the horizontal crossbar from the corner. The structure is reinforced with kerchiefs, we weld them from the bottom of the steps towards each of the stringers.
Along the edge of the square pipe from the profile, we make markings and, according to the marking, we weld the filly to the edge of the kosour, the second kosour is attached to the first kosour with fillets and transfer the marking.
We check the level and then weld the stringers with the lower end to the support platform. If the houses have a concrete foundation, then the support platform is installed in concrete. We attach the upper end to the support post, the support post is fixed to the ceiling between the floors with steel anchors. Then once again the filly must be checked by level.
In the event that the staircase is made near the wall, then to give the structure, rigidity, one stringer is welded to the brackets that are fixed to the wall.
Finishing work consists in welding the steps to the filly, you can also fix them with bolts, but in this case it is necessary to sheathe the steps with wood. Also, the steps can be installed wooden, on the filly using screw connections.
It seems that the construction of an interfloor staircase is not such a difficult task, but this work requires precision, accuracy and care ...
In the article, we described how to make a metal staircase to the second floor.
Of course, it is up to you and no one else to decide what material to make a staircase from, but a staircase made of metal turns out to be visually light, so we recommend this particular design.
We hope this information was useful to you. We wish you good luck, patience and inspiration!
