14, according to the size of the staircase between the staircase width B and ladder width.
15, to determine the step number of curse, adjust the stepping high chu and step width b, with a layer of high H divided by stepping high h, step step n ≈ H / h, when the decimal, when the integer, and adjust the step high h (H ≈ H / n), using the formula b + h = 450 (mm), or b + 2h = 600 ~ 620 (mm), determine the step width b.
Stair step size
1, in order to avoid the upper and lower stairs when the illusion, the stairs of the first step and the last level of the height should be consistent with other levels. If you want to change, should be controlled within 4 cm, preferably not more than 2 cm to 3 cm is appropriate
