[0002] The edge operations during the construction of building steel structure corridors are all high-altitude operations with a high risk coefficient. It is of utmost importance to do a good job in edge protection during the construction process. The edge protection device improves the safety of edge operations and ensures the life safety of operators. At present, the general protective measures taken for the edge operations during the construction of steel structure corridors are to set up traditional detachable edge protection devices. The traditional detachable edge protection devices commonly used at present have a relatively simple structure.

This situation of fastening only from one side of the wing plate of the main girder has a relatively high safety risk. Content of the Utility Model
