[0002] Scaffolding refers to various supporting structures erected on construction sites to facilitate worker operations and vertical and horizontal transportation. It's a common term in the construction industry, referring to scaffolding used on construction sites for exterior walls, interior decoration, or areas with high ceilings where direct construction is impossible. Its main functions include facilitating worker movement up and down, providing safety netting, and installing components at heights.

Assembled scaffolding is prone to collapse due to excessive material accumulation, concentrated loads, or vibrations causing fasteners to loosen or slip. Alternatively, defects in steel pipes and fasteners can lead to insufficient strength and ductility, further threatening the safety of construction workers and pedestrians. Therefore, there is an urgent need to develop a reinforcement and anti-loosening structure for the connection joints of prefabricated building exterior wall scaffolding to overcome the shortcomings in current practical applications.

The movable slide 8 is fixedly connected to the clamping and locking unit 2 on the other side. The movable slide 8 is also fixedly connected to the locking frame 11 disposed on the inner side of the support plate 1. Several locking devices 12 are disposed between the locking frame 11 and the inner wall of the support plate 1. One end of the locking device 12 is fixedly connected to the locking frame 11, and the other end is fixedly connected to the locking plate 13, which are used to cooperate with the support plate 1 to lock the movable slide 8 after rotation.

[0031] In this embodiment, the locking device 12 is an electric push rod, and a brake pad is fixedly installed on the contact surface between the locking plate 13 and the inner wall of the support plate 1. The brake pad is made of a high friction coefficient material. During installation, the movable slide 8 is rotated according to the angle of the scaffold poles on both sides at the connection node, and the angle of the clamping locking unit 2 on both sides is adjusted accordingly. The locking device 12 drives the locking plate 13 to move closer to the inner wall of the support plate 1.

Air inside the other side of the transmission control box 10 enters the control groove 18 along the fixed pipe 24. The air enters the inner side of the sealing ring 17 and then enters the inner side of the synchronization groove 19 along the ventilation pipe 22, thereby extracting the air inside the sub-control chamber 36. The air inside the sensing groove 39 enters the inner side of the sub-control chamber 36, and works with the sensing piston 40 to complete the retrieval of the take-up and release frame 35. The two movable frames 28 move relative to each other, and the trapezoidal clamps 33 on the movable frames 28 cooperate to clamp and lock the scaffold poles, thereby locking the scaffold poles on both sides of the connection node, ensuring the reliability and safety of the connection, and preventing loosening.
