[0002] Scaffolding is a working platform set up to ensure the smooth progress of each construction process. It can be divided into external scaffolding and internal scaffolding according to the location of the erection. It can be divided into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding according to different materials. It can be divided into vertical scaffolding, bridge scaffolding, portal scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding according to the structural form.

[0003] When assembling the steel pipe scaffolding, the scaffolding cross bar steel pipe and the scaffolding sleeve are connected by punching holes through the connecting structure to assemble the scaffolding cross bar steel pipe and the scaffolding sleeve. The connecting structure and the scaffolding sleeve can install and limit multiple sections of scaffolding cross bar steel pipes, which is helpful for the use of the steel pipe scaffolding.

[0004] However, when the existing connection structure is used, it is not conducive to adjusting the connection angles between multiple sections of scaffolding crossbar steel pipes. When it is necessary to connect scaffolding crossbar steel pipes at different angles, different scaffolding sleeves and connection structures must be replaced, which will affect the application range of the connection structure and is not conducive to the use of the connection structure.

[0005] Therefore, we proposed a scaffolding crossbar steel pipe and casing punching connection structure. Utility Model Content

[0036] The working principle of the utility model is: during use, when it is necessary to connect and install the first scaffolding steel pipe 1 and the second scaffolding steel pipe 2 at different angles, the first nut 8 is rotated and removed along the first bolt 5, so that the first nut 8 cancels the limit on the first bolt 5, and the first bolt 5 is further rotated and removed. After the first bolt 5 is rotated and removed, the first bolt 5 cancels the limit between the first mounting plate 13 and the second mounting plate 14, and the first mounting plate 13 and the second mounting plate 14 are further separated.

[0037] After separating the block 17 on the second mounting plate 14 from the slot 18 on the first mounting plate 13, the second mounting plate 14 is rotated along the outer side of the first mounting plate 13.
