Description

Technical Field

[0001] The utility model relates to the technical field of building construction scaffolds, in particular to a scaffold connection lock structure. Background Art

[0002] Scaffolding is an indispensable auxiliary tool in construction. Scaffolding is built on the outside of the building's exterior wall to help construction workers in the exterior wall construction and painting the building's exterior wall. The connecting locking structure is indispensable for the scaffolding to be assembled.

[0003] At present, most of the scaffolding connection locking structures include a support plate welded and fixed to the outer surface of the main body. The scaffolding can be built up layer by layer by supporting and fixing it through the support plate, and connecting and fixing a number of sub-tubes with the support plate. However, in actual operation, it is found that since the support plate is connected to the main body by welding, and after the scaffolding is built, the weight of the scaffolding is all concentrated on the welding point between the support plate and the main body. If defects such as cold welding occur during welding, it is easy to cause the scaffolding to break at the stress point when it is in use, which poses a certain safety hazard. Therefore, it is necessary to design a scaffolding connection locking structure with a more stable connection and multiple stress points to solve the above problems. Utility Model Content
