[0002] Prefabricated construction refers to the transfer of a large amount of on-site work in traditional construction methods to factories, where building components and accessories are processed and manufactured in factories and transported to the construction site. During on-site installation, the position of the building's frame must be determined first, and then accessories such as floor slabs must be gradually installed on the frame for assembly.

[0003] When installing the longitudinal and transverse beams of prefabricated buildings, the position of the longitudinal beam is usually determined first, and then the transverse beam is hung at the top of the longitudinal beam using a crane or other equipment, aligned with the position, and then fastened with bolts in sequence. However, in the process of fastening the transverse beam to the top of the longitudinal beam, the transverse beam may shake, causing the angle of the bolt to deviate when tightening, which may cause the bolt to break due to uneven force, affecting the stability of the crossbeam and longitudinal beam during assembly. Utility Model Content

[0012] The effect achieved by the above components is that when the rectangular frame moves, the outer surfaces of the two positioning blocks will slide on the inner walls of the positioning grooves to further limit the angle between the rectangular frame and the L-shaped plate and the longitudinal beam, thereby avoiding the angle of the rectangular frame from being deflected as much as possible.

[0013] Preferably, an inclined plate is fixedly connected to one side of the L-shaped plate, and two ends of the inclined plate are fixedly connected to two ends of the outer surface of the L-shaped plate.

[0014] The effect achieved by the above components is that the outer surface shape of the L-shaped plate can be reinforced by arranging the inclined plate to avoid deformation of one end of the L-shaped plate when a force is applied.
