Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, and more particularly to a temporary protective device for stairs. Background Art
[0002] Conventional stairwell and floor construction requires either temporary removal of edge protection, leaving workers without safety tie-down points and engaging in dangerous work. Alternatively, edge protection is left intact, leaving a construction gap between the floor and the edge protection, requiring secondary construction, which is time-consuming, labor-intensive, and inefficient. If formal handrails are installed prematurely, they will conflict with the temporary protection and will still need to be removed. Furthermore, the formal handrails can affect the quality of the stair tiles, making tile laying more difficult and slowing down construction progress. Therefore, traditional processes cannot meet the safety, quality, and progress requirements of on-site construction, necessitating the use of a new type of edge protection to address these issues.
