The steel columns are prone to shaking when the crane moves them, which is not convenient for rapid assembly of the steel supports. The construction steel supports are easily oxidized with oxygen and water vapor in the air underground, forming a layer of rust on the surface. The rust causes the steel supports to rust, and the steel supports need to be maintained regularly. The steel supports are high and concentrated in number, and the manual cleaning and repair operation process is cumbersome, and the rust cannot be cleaned quickly, making it inconvenient to maintain the steel supports.

Specifically, during the docking process between the cross column 2 and the steel column 1, the cross column 2 slowly falls, so that the cross column 2 abuts against the pressure block 6, so that the pressure block 6 moves and applies pressure to the compression spring 9 to shrink the compression spring 9. While the pressure block 6 moves, the tooth groove 8 and the gear 4 are meshed and transmitted, and then the gear 4 rotates with the movement of the pressure block 6, so that the clamping block 5 is meshed and transmitted with the gear 4 through the tooth groove 8, so that the clamping block 5 moves and is inserted into the clamping groove 7, and finally the cross column 2 is limited, so that the cross column 2 is not easy to deviate and dock accurately, and then the rapid assembly of the steel support is realized through the cooperation of the screw hole and the nut.
