[0002] Steel frame connection refers to fixing steel structural components or parts of a building together using specific connection methods to form a stable overall structure. Common steel frame connection methods include welding, bolting, and riveting.

[0003] Steel is characterized by high strength, light weight, good overall rigidity, and strong deformation capacity, making it particularly suitable for constructing large-span, super-high, and super-heavy buildings. It also has good homogeneity and isotropy, making it an ideal elastic body that best conforms to the basic assumptions of general engineering mechanics. Furthermore, it has good plasticity and toughness, allowing for large deformations and effectively withstanding dynamic loads. Construction time is short, and its high degree of industrialization enables highly mechanized and specialized production.

[0004] Chinese Invention Patent Publication No. CN 110306661 A discloses a steel frame component for a central column of a steel structure building. The device has U-shaped mounting plates welded to the sidewalls of the steel frame column. Two locking plates are welded to the side of each U-shaped mounting plate facing away from the steel frame column. A frame beam is provided on one side of each U-shaped mounting plate. A first bolt is threaded to one side of each locking plate, and the locking plate is fixedly connected to the frame beam via the first bolt. Four positioning columns are fixedly connected to the top of the frame beam. Each positioning column has an external thread at its upper end, and connecting rods are sleeved on the surfaces of adjacent positioning columns. Locking sleeves are connected to the surfaces of the positioning columns via external threads.

[0005] The above-mentioned device is relatively complicated to install, inconvenient for workers, and not very stable, making it inconvenient to use. Utility Model Content
