Description

Steel construction building stair

Technical Field

The utility model relates to a steel construction building stair belongs to steel member technical field.

Background

Steel structure stairways are now being used more and more in buildings, including residential buildings, office buildings and factory buildings. When each building is constructed, the height of each layer is slightly different, and the height of the stairs is different, so that the height of the stairs with the steel structures is not uniform, the stairs with the steel structures are inconvenient to prefabricate, and each stair with the steel structures cannot be reused. The production cost is increased and waste is caused. And most of the existing steel structure stairs are not detachable, so that the transportation and the storage are very inconvenient, and a large space is occupied.
