Abstract
The invention provides a scaffold pulling and connecting device and a scaffold pulling and connecting method. Because the pre-buried sleeve sets up the position more nimble, the sleeve location can utilize anchor reinforcing bar and structural steel welded fastening, and the process of vibrating also should not be influenced. The direction of the pulling and connecting piece can be adjusted, and one end of the pulling and connecting piece is firmly connected with the upright post node part of the scaffold. In the device, except the sleeve and the anchoring steel bar which are pre-embedded on the side surface of the cast-in-place concrete, other parts can be recycled and reused. The contact surface of the device and the cast-in-place concrete structure is only the area of one sleeve, so that the subsequent wall surface painting and the like are slightly influenced; meanwhile, the sleeve is buried in a cast-in-place concrete structure, and the risk of leakage at the position of a pulling joint does not exist.
