Garden stairs, part 3

This recommendation follows from this, that by walking along the steps of a certain width, the same stride length is maintained (move), that is, a specific rhythm of ascent. This rhythm should be maintained as you pass through the landing. Adding one more width to a multiple of a move is to cause the next gear to go to a different foot than the previous one.. If the landings are longer than 2,5 meters, it is not necessary to determine their length according to the given formula. Each landing should have a slope that allows water to run off its surface. However, the water should not be discharged downstream. This is especially important, if the staircase consists of separate elements, because water seeps into the crevices underneath the structure (such stairs can cause the soil to soften and wash away. The most rational way of collecting and draining water from the landing surface is to use a drain covering the entire width of the stairs.

Some stairs are built with narrow ramps in the plane of the run, enabling prams to be brought. This solution is opposed by designers, because very often the carts are not brought down the ramps in a horizontal position (on two wheels), but rides down normally, which is dangerous due to the possibility of children falling out. Such ramps on flights of stairs with greater inclines are particularly dangerous.

Usually the width of the stairs is a multiple of the lane, the width of which is taken equal 65-70 cm. The most common wide staircase is used 1,5, 2,0 i 2,5 or 3,0 m; further widths usually increase by one meter. The stairs on the road should never be narrower.
