High-altitude square steel stand column top cutting operation safety auxiliary device

The utility model discloses a high-altitude square steel stand column top cutting operation safety auxiliary device. The device comprises an upper constraint structure and a lower constraint structure which are coaxially spaced up and down; the upper constraint structure and the lower constraint structure are fixedly connected through supporting reinforcements; the lower constraint structure is provided with a hole for connecting a locking bolt in the horizontal direction; a hole which is matched with the shape of square steel to be arranged in a sleeving manner is formed in the upper constraint structure and the lower constraint structure. The device has the beneficial effects that arranged vertical square steel is not required to be cut after being disassembled but the operation can be directly performed on the top of the square steel, so that a large amount of human input is saved, the construction period is saved, the controllability of the cut square steel during high-altitude operation can be effectively guaranteed, the potential safety hazard of falling from high altitudes does not exist, and the device is economic and applicable and can be repeatedly used.
