Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding wall connection, in particular to a novel scaffolding wall connection piece. Background Art

[0002] Scaffolding is a variety of supports erected at construction sites for workers to operate and work at heights. It is a general term in the field of construction and 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; currently, 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, mining, etc. Back to the field of construction, the scaffolding currently used is mainly erected according to predetermined specifications using steel pipes, connecting clips and other components. It is impossible to temporarily add the required fixed structure to the existing frame during the erection process, and different specifications of steel pipes are required for different parts of the frame, resulting in a large variety of scaffolding materials and a complex frame structure. Too much labor is required during the assembly and disassembly process. Wall connecting parts refer to components that connect the scaffolding frame to the main structure of the building and can transmit tension and pressure, which mainly play a rigid connection role.

[0003] The publication number is CN117684738A, which discloses a scaffold wall connection member, including: a base, which is used to be fixed on a wall or the ground, and is provided with bolt holes for assembling bolts; an assembly pipe, which can be detachably assembled on the base, and is used to connect with the steel pipe of the scaffold; a radial support member, which is fixedly arranged on the base, and is used to radially support the assembly pipe after being assembled with the base. The base can be connected to the ground or the wall by bolts, and does not need to be pre-buried. When the formwork frame is removed in the later stage of construction, the base can be assembled at the required position by expansion bolts according to the structure of the scaffold, and the scaffold is supported and fixed by the assembly pipe and the base.

[0004] As in the above application, the existing scaffolding wall connecting parts can generally be connected and fixed between the wall connecting parts and the wall by embedding expansion bolts in the wall and cooperating with bolts. The disadvantages are that the disassembly and assembly are troublesome, the construction is not easy, the construction time is prolonged, and the expansion bolts embedded in the wall are easy to cause damage to the wall, resulting in problems such as water seepage in the wall.
