Description

Technical Field

[0001] The utility model discloses a rotatable clip-on roof parapet edge protection, belonging to the technical field of edge protection. Background Art

[0002] In the era of reinforced concrete structures, after the main body of the reinforced concrete structure was capped, the construction of the roof machine room structure, roof equipment foundation, parapet, etc. began. After the construction of the roof machine room structure and parapet, the external protection frame of the main structure will generally be gradually removed. Before the external protection frame of the roof layer structure is removed, the roof layer needs to be equipped with edge protection to ensure safe operation during the roof construction process. The roof edge protection is generally directly built on the roof structure layer. During the roof construction, although the edge protection frame ensures the safety of the operation, since the frame is located on the roof structure layer, it affects the construction of the roof layer. The operators will generally lift the frame and lower it to the roof after the roof construction is completed. In the process of lifting and lowering the protection frame, the operators are working on the edge, and the lifting and lowering consume a lot of manpower. The operators are very resistant. Some operators even directly remove the frame, which is illegal and poses a great safety hazard. Utility Model Content
