[0035] Working principle: When in use, the height of the construction frame is adjusted by an external lifting device, the construction frame is lowered to a low position, and the outer rotating handle 45 is turned to drive the rotation of the bidirectional threaded rod 37. The bidirectional threaded rod 37 drives the two threaded sleeves 36 to move closer to or away from each other through two threads in opposite directions. The two threaded sleeves 36 move away from each other, that is, the telescopic door is opened, which is convenient for the transportation of pedestrians and materials to the shelves. After the pedestrian enters the construction frame, the rotation of the bidirectional threaded rod 37 is controlled by rotating the inner rotating handle 45 to close the telescopic door to prevent the pedestrian from falling and the material from sliding. At the same time, a safety belt connection structure is provided, and the safety belt hanging ring 55 is connected to the construction personnel through the safety belt, and because the safety belt hanging ring 55 can slide horizontally and vertically, the safety belt hanging ring 55 can follow the movement of the construction personnel on the bamboo plywood 6 to maintain the maximum protective effect of the safety belt.
