Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding, in particular to a scaffolding connection structure used in construction engineering. Background Art

[0002] The scaffolding connection structure is a component used to connect the various parts of the scaffolding together to form a complete supporting structure. Scaffolding usually uses steel pipes as the main component material, which can realize the standardization and modular design of the scaffolding. In the scaffolding, the transverse steel pipes are usually used as a component of the transverse cross-supporting structure to increase the stability and load-bearing capacity of the scaffolding. The transverse steel pipes on the scaffolding are prone to deformation when subjected to loads. The bent and deformed steel pipes may reduce the load-bearing capacity of the scaffolding. The auxiliary support of the transverse steel pipes through the connection structure can effectively reduce the degree of bending deformation of the transverse steel pipes, and at the same time can further enhance the load-bearing capacity of the scaffolding.

[0003] After searching, the Chinese patent with the authorization announcement number "CN216429004U" provides "a scaffolding connection structure for construction sites, which replaces the clamping and welding operation of the existing buckle scaffolding with a head and a fixing block, making it convenient for users to disassemble and replace the scaffolding, and the fixing parts and the buckles are clamped to achieve the required structural strength and enhance the use effect." Although the device can facilitate the disassembly and replacement of the scaffolding, it cannot provide auxiliary support for the horizontal steel pipes on the scaffolding, and the bearing capacity of the horizontal steel pipes is low.
