There are stairs on which it is very scary to stumble. As practice shows, most often such unsafe structures are erected in dachas or apartments, t. e. In those places where the owners tried to leave the inner useful space as much as possible.
Naturally, for an adult with a good vestibular apparatus, it will not be difficult to rise on such a difficult rise. But it may happen that the family has children or elderly people? Plus, it often happens that you need to go down very quickly or get up!
In order for the design of the stairs to be convenient, and moving along it is safe, the following points should be taken into account during construction:
The width of the main staircase march should be from 1 – 0, 9 m – with such a decision, “traffic jams” will not turn out on it, since even several people will be able to calmly disperse.
In suburban dachas, construction of less than 0.8 m wide can be allowed, this is relevant if it is rarely used.
The revolutions of the stairs depends on the height and length of the structure and how the these values are related to each other. To do this, you can draw an imaginary line between the beginning and the descent point to estimate how steep the staircase will turn out. As practice shows, the resulting angle will be from 20C-50C, and in correctly when the numbers show 30-45C.
Before starting work on the construction of the structure of the stairs, be sure to calculate all the nuances, since even the ladder is not comfortable to rise, if the size of the downside and the approaching is calculated incorrectly.
