[0002] With the rapid development of the economy, there are more and more high-rise buildings in cities. The requirements for civilized construction, safety protection, and green environmental protection construction at the construction site of high-rise building projects are becoming more and more stringent, and higher requirements are also put forward for safety protection at the construction site. For safety protection during the construction of high-rise buildings, cantilever scaffolding plays a key role. Cantilever scaffolding generally uses cantilever beams as the scaffolding foundation, and forms a construction layer by setting up crossbars and laying scaffolding boards on the cantilever beams. A closing device needs to be set at the bottom of the cantilever beam to prevent materials from falling.

[0003] Currently, the commonly used bottom closure devices for cantilever scaffolding include dense mesh plus horizontal net, wooden scaffolding with warning paint, or hanger plus thin steel plate.
