[0002] Scaffolding is a kind of support set up for workers to operate and work at heights at the construction site. It is a general term in the field of construction. It is mainly used on construction sites for exterior walls, interior decoration or places where the floor height is too high to be directly constructed. Scaffolding materials are usually bamboo, wood, steel pipes or synthetic materials. 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, traffic roads and bridges, mining, etc. Back to the field of construction, the scaffolding currently used is mainly set up according to predetermined specifications using steel pipes, connecting clips and other components. However, due to design defects, the safety performance of existing scaffolding is relatively poor. During use, if the construction workers or tools accidentally fall, they cannot be effectively protected. There are many safety hazards; therefore, based on the above problems, it is necessary to make further improvements to the structure of the existing scaffolding. Utility Model Content
