Description

Technical Field

[0001] The present invention belongs to the technical field of building steel structures, and more specifically, particularly relates to a connecting member for prefabricated building steel structures. Background Art

[0002] Steel structure buildings are a new type of building system. Compared with traditional concrete buildings, steel plates or steel sections are used to replace reinforced concrete, with higher strength and better seismic resistance. Connecting members are generally used for connection in steel structures.

[0003] For example, Chinese Patent with the publication number CN221030652U discloses a connecting member for beam-column of prefabricated building steel structure, including a support column. A fixed sleeve is arranged outside the support column, and a connecting mechanism is arranged on the outer wall of the fixed sleeve. The connecting mechanism includes a U-shaped seat. The outer wall of the U-shaped seat is fixedly connected to the outer wall of the fixed sleeve. The bottom of the inner wall of the U-shaped seat is fixedly connected with a limit seat. A lifting groove is opened on the opposite surfaces of the limit seats. A spring groove is opened inside the limit seats. A spring is fixedly connected to the bottom of the inner wall of the spring groove. The top of the spring is fixedly connected with a lifting plate. A fixed column is fixedly connected to the outer wall of the lifting plate. A telescopic block is arranged between two adjacent limit seats. The bottoms of the two telescopic blocks are fixedly connected with sliders. Oblique grooves are opened inside the two telescopic blocks. The fixed column is located inside the lifting groove and the oblique grooves. In this utility model, through the lifting plate, the fixed column, and the telescopic block, the separation process of the support column and the cross beam is simple, time-saving and labor-saving.

[0004] Although the implementation scheme of the above patent has the advantage of convenient use, it does not have the functions of drilling position marking and auxiliary reinforcement support. Specifically: when the current connecting member is in use, it is necessary for workers to pre-drill holes on the steel structure in advance, and then connect the connecting member with the drilled steel structure through bolts. Since there is no marking before drilling the steel structure, the holes on the steel structure are likely to be misaligned with the connecting member, affecting the connection accuracy of the steel structure. Moreover, in order to improve the portability of the connecting member, the contact area with the steel structure is usually small, and it cannot provide good support for the bottom of the steel structure after connection, resulting in low stability of the steel structure after connection.
