Hoop type steel supporting structure

The utility model relates to the technical field of steel support connection, and provides a hoop type steel support structure which comprises a main supporting pipe, hoops arranged on the two sides of the outer surface of the main supporting pipe and auxiliary supporting pipes fixedly installed on the outer surfaces of the two hoops, and a connecting mechanism is arranged between the two hoops. Threaded sleeves are installed on the outer surfaces of the two hoops and located on the upper side and the lower side of the auxiliary supporting pipe in an embedded mode. A rotating handle is rotated to drive a screw rod to move towards the inner side of a hoop under the action of a threaded sleeve, so that an arc-shaped plate is driven to move towards a small supporting pipe, the arc-shaped plate drives a guide rod to slide in a through hole, the arc-shaped plate is guided, the guide rod is prevented from deviating in the moving process, and the service life of the arc-shaped plate is prolonged. After the arc-shape
