However, in actual projects, when its span exceeds the specified safety distance, it is still necessary to build scaffolding at the bottom of the steel truss floor decking as support. Since the heights of the floors are not consistent, multi-layer scaffolding needs to be built, and workers need to climb high to operate. The construction and disassembly process is time-consuming and labor-intensive, and the safety is relatively low. Utility Model Content
