Description

Technical Field

[0001] This utility model relates to the field of metal frame connection technology, and more particularly to a connecting iron plate structure and protective frame for metal frames. Background Technology

[0002] During construction, in addition to wearing safety helmets, workers must also take appropriate safety precautions when working on climbing scaffolds, especially for work at heights. Therefore, construction climbing scaffold mesh panels have emerged. These panels mainly consist of a support frame and protective mesh panels, connected to the uprights of the climbing scaffold. This effectively protects the construction site, preventing workers from falling or encountering other dangers, ensuring personal safety, and guaranteeing the efficient progress of construction work. However, existing common protective mesh panels often lack sufficient securing structures between multiple panels. As a result, individual panels are prone to falling due to broken wire ties, posing a significant safety hazard. Utility Model Content
