S4: rotating the U-shaped groove connecting piece at the other end of the fastening device to a proper position of the cross rod so that threaded holes on vertical surfaces at two sides of the U-shaped groove connecting piece correspond to and penetrate through the bolt holes of the cross rod at the position; the U-shaped groove connecting piece is fixed on the cross rod by using another fastening bolt, and a gap is reserved between the cross rod and the U-shaped groove connecting piece, so that the U-shaped groove connecting piece can flexibly rotate along the side vertical surface of the cross rod in the step;
S5: the adjusting tool is utilized to pass through the adjusting hole on the adjusting sleeve and extend out of the adjusting hole by a certain distance, and the adjusting sleeve is rotationally screwed down by utilizing the lever principle, so that the structural beam template reinforcing device is clamped and fixed on the structural beam template;
S6: and in the process of pouring the beam body concrete, the adjusting sleeve is screwed down in a rotating way so as to ensure that the reinforcing device and the structural beam template do not fall off.
2. The method for reinforcing the structural beam formwork without split bolts according to claim 1, wherein the method comprises the steps of: in the step S2, the cross rod, the movable vertical rod and the pipe sleeve are all manufactured by galvanized square pipes; and step S3 and step S4, the two U-shaped groove connecting pieces are manufactured by cutting galvanized square pipes.
