Description

Technical Field

[0001] This invention relates to prefabricated stairs, and more specifically, to a method for installing prefabricated stairs. Background Technology

[0002] Staircases are the passageways for people to walk up and down between different floors of a building. In prefabricated buildings, prefabricated staircases occupy a very important position in the entire building system. As the main vertical transportation and emergency evacuation route of a building, staircases have a significant impact on the normal use and emergency evacuation of the entire building. The prefabrication of staircases is also one of the main indicators of the prefabrication rate of prefabricated buildings.

[0003] In patent document CN205242892U, a prefabricated staircase and its installation method are proposed, including a sloping ladder beam and several steps; the sloping ladder beam is a steel sloping ladder beam; the steps include steel U-shaped step grooves, in which prefabricated load-bearing components are placed and filled with concrete. In this invention, the steps are connected to the ladder beam by welds or connectors, and are assembled in the factory or on-site. This invention organically combines the advantages of steel structure staircases—light weight, convenient construction, and high prefabrication rate—with the advantages of concrete staircase steps—good sound insulation, vibration resistance, and high comfort. However, in the aforementioned document, although the staircase assembly and installation are completed, the width between each step must be consistent during the assembly process. Positioning between adjacent sets of steps is difficult, leading to errors during installation and inconsistent widths, affecting the usability of the steps. Summary of the Invention
