The binding type operation is simple, but the cooperative stress performance is worst, the structural steel bar can be cut off from the binding type operation, and then the binding type operation is welded and fixed with the steel bar meter, so that the possibility that the welding current is damaged through the steel bar meter exists, the possibility that the steel bar meter is damaged due to overhigh temperature caused by the welding operation exists, and the survival rate of the steel bar meter is low. In the chinese patent of publication No. CN216483618U, in order to avoid the drawbacks of binding and welding, the reinforcement gauge is first connected with the connecting reinforcement, and then the structural reinforcement and the connecting reinforcement are connected by using the double-bolt assembly, and four bolts, two for connecting the square saddle buckle, and two for abutting the connecting reinforcement and the structural reinforcement one above the other respectively, but the shape of the reinforcement is round, and the manner of abutting the reinforcing bars by the upper and lower bolts is difficult in actual operation, and the stability is to be improved.
