Background

Stairways are components of buildings that are used for vertical traffic between floors. The method is used for traffic connection between floors and when the height difference is large. The stairs are composed of continuous stair sections (also called stair runs), platforms (rest platforms), enclosing members and the like. The horizontal projection distance between the lowest step and the highest step of the stair is the length of the stair, and the total height of the steps is the height of the stair. Stairs have been engraved in the heavy room image on the copper ware in the warring period of China. In italy of the 15-16 th century, the indoor stairs are liberated from the traditional closed space, so that the indoor stairs become building components with varied shapes and decorative effects. At present, in multi-storey and high-rise buildings provided with elevators and escalators as main vertical transportation means, stairs are also reserved for escape in case of fire. The house type of a jump layer structure has appeared in the building at present to and have the loft on some little house types, these houses are in order to the more abundant utilization of space, all can install the stair usually. Most of the existing stairs are fixed, occupy a large space of a bottom room and bring inconvenience to life.
