Background Art

Scaffolding is a working platform set up to ensure the smooth progress of each construction process. According to the location of the scaffolding, it can be divided into external scaffolding and internal scaffolding; according to different materials, it can be divided into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; according to the structural form, it can be divided into vertical pole scaffolding, bridge scaffolding, door scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding. Scaffolding is a variety of supports set up at the construction site for workers to operate and work at height. It is mainly used on construction sites for exterior walls, interior decoration, or places with high floor heights that cannot be directly constructed. At present, scaffolding is also used as a template in some projects. In addition, it is also widely used in the fields of advertising, municipal administration, transportation roads and bridges, and mining. In the construction field, the scaffolding currently used is mainly constructed by using steel pipes, connecting clips and other components according to predetermined specifications. The scaffolding frame structure is complex, and excessive manpower is required during the assembly and disassembly process. At the same time, the consistency of the connection structure of different parts of the frame is low during assembly. The uncertainty caused by human factors in the assembly process also increases, resulting in many safety hazards in the frame.
