Description

A kind of cantilever scaffolding cantilever layer construction edge protection structure

Technical field

The present application relates to the field of construction scaffolding, and in particular to an edge protection structure for cantilevered layer construction of cantilevered scaffolding.

Background technique

Building-style buildings can be seen everywhere in modern society. When the number of floors in a building is too high, it is necessary to use cantilevered scaffolding to provide construction workers with a fulcrum to facilitate high-altitude operations.

At present, when most buildings are carrying out roof caving operations, they need to set up cantilever beams on the operation floor to set up scaffolding. However, the current side scaffolding does not extend to the operation floor because it needs to be connected to the cantilever beams. For workers working on the operating floor, the adjacent scaffolding cannot provide effective shielding and poses certain safety risks.
