Description

Technical Field

[0001] The utility model relates to the technical field of traditional building and prefabricated building construction, and in particular to a plane protection device for elevator shafts and stairwells which is convenient for construction. Background Art

[0002] In the construction of high-rise buildings, various construction safety accidents at edges and openings occur from time to time, especially elevator shaft accidents. It is located inside the building and the space is small, which is not convenient for construction operations such as formwork. Therefore, during the construction of the building elevator and the early stage of the elevator shaft construction, it is mostly necessary to lay a protective net on the elevator shaft to prevent accidents to construction workers and to prevent impurities and garbage from falling down the elevator shaft.

[0003] After the existing protective net is installed, pedestrians can walk on it because the protective net is a rigid structure, which is convenient for construction workers to walk around and inspect. However, the mesh structure means that there is no good force point for the feet of construction workers when they pass by, and construction workers are prone to fall, resulting in certain safety risks when the protective net is used. In summary, the existing elevator shaft and stairwell plane protection devices still have the following problems:

[0004] Although the flat mesh design of the protective device is convenient for people to walk on, the mesh structure makes it easy for construction workers to fall when passing by. Utility Model Content
