Abstract

The invention relates to a steel stair. A steel stair is also used in an existing steel structure building, the steel stair is generally formed by folding or welding a steel plate, the steel plate is a flat steel plate, the thickness of the used plate is large, and the manufacturing cost is high. The steel stair comprises steps, wherein each step is provided with a set of regular grooves, the length direction of the regular grooves is perpendicular to the width direction of the step, and a side sealing plate and / or a side plate is arranged at the side end of each step. The steel stair is used as a building component.

Description

technical field

[0001] The invention belongs to the field of civil engineering and relates to stairs used in concrete buildings and steel structure buildings. Background technique

[0002] The stairs used in traditional reinforced concrete buildings are concrete stairs. The manufacturing process is complicated, and a large amount of high-energy-consuming materials such as cement and sand are consumed. The cost is high, and it is not energy-saving and environmentally friendly. Steel stairs are also used in existing steel structure buildings. Steel stairs are generally formed by folding or welding steel plates. High cost is also an important reason why steel stairs are difficult to promote. Contents of the invention

[0003] The present invention improves the shape coefficient of the stairs by changing the geometric shape of the steel plate, and provides a new type of stairs with low cost, material saving, and industrial production line production.
