[0002] 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. Fasteners generally refer to the middle connecting parts connecting two components. In construction projects, they are mostly used to fix steel pipe scaffolding with an outer diameter of Φ48mm. Fasteners are divided into right-angle fasteners, rotating fasteners, butt fasteners, etc.

[0003] During the construction process at a construction site, it is usually necessary to use scaffolding to carry out high-rise construction of buildings. When fasteners are used to fasten and fix the scaffolding steel pipes to each other, screws are usually used to tighten and fasten the scaffolding steel pipes to each other. Because the fasteners are in direct contact with the surface of the scaffolding, the diameter of the scaffolding steel pipes will shrink under the influence of external natural factors. At the same time, the rotating screws will rust and loosen after being used for a long time, resulting in a gap between the fastener and the scaffolding contact surface, causing the fastener to loosen and slide downward, making the scaffolding as a whole unstable. Therefore, the utility model proposes a building scaffolding fastener to solve the problems existing in the prior art. Utility Model Content
