Background

The building is used as a component for vertical traffic between floors. The method is used for traffic connection between floors and when the height difference is large. Stairways are also provided in multi-story and high-rise buildings provided with elevators and escalators as the main means of vertical transportation. High-rise buildings, although using elevators as the main vertical transport means, still need to keep staircases for escape in case of fire. 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. In the design process of the stairs of modern buildings, the using environment of the stairs is required to be emphasized, and anti-skid treatment of the stairs under different conditions is also required to be emphasized. For example, in rural areas in China, because the dust that exists in the surrounding environment is more, the resident of a large proportion can contact with earth, simultaneously because the resident of family and external environment direct contact, people who often come and come in rainy and snowy weather can bring the rainwater into the room inevitably, and these earth and rainwater can bring the puzzlement for family's clearance, therefore the stair design in rural areas adopts marble floor preparation mostly, and the antiskid on marble floor generally adopts to set up anti-skidding groove.
