In houses with a second floor or equipped with an attic, naturally, you can’t do without a staircase. You can make it from different material. But the easiest to execute, nevertheless, a marching wooden staircase. With your own hands, it will be able to make it and install not even a professional who has at least some kind of work with a tree.
But before starting work, you should draw up a special scheme that determines the sequence of work. The same scheme will help determine the number of steps, their width and angle of inclination of the stairs, based on the height of the room.
The marching stairs themselves can be of two types: with the stuffing of steps over the load -bearing beams (Kosour), or the side fastening of the steps through a wooden aunt.
The lower part of the bearing beam is reliably connected to the floor of the lower floor, the upper end of the beam, respectively, with the ceiling, again the lower floor or with the wall.
Sovele on a bowing a bow. And on them already lay the planks of the steps themselves.
If the connection of the steps is performed by the method of the bowstring, then the staircase should additionally be strengthened by supporting bars, which should be installed at the same distance from each other. When attaching steps on Kosuurs, there is no such need for additional insurance.
When choosing a material for installing a marching staircase, it should be borne in mind that both a trim for a bowstring and bars for steps should have the same section. To connect the elements of the stairs, use screws made of stainless steel.
The number of steps is determined, as a rule, the height of the room and the angle of inclination of the stairs. In this case, all steps should be the same size. If more than 10 steps are “typed” in the design of the marching staircase, it is recommended to divide the stairs with a small platform. This, in turn, will make it possible to “re -qualify” the march structure into the screw, slightly changing the focus of the next span of the steps (if it really requires execution).
