Description

Technical Field

[0001] This utility model relates to the field of steel structure connection technology, specifically to a connection structure between a steel structure transfer layer and a steel beam. Background Technology

[0002] When the upper and lower parts of a building have different functions on the floor plan, and the upper and lower parts of the floor adopt different structural types, and the structure is transferred through this floor, then the floor is called a structural transfer floor. Especially in steel structure buildings with large spans, the upper and lower parts of the floor need to use transfer floors for structural transfer, and the transfer floor and the steel structure are usually directly connected by welding.

[0003] The announcement number CN221682066U discloses a weld-free connection device for a large-span steel structure transfer layer, including a steel frame, three front clamps, and three rear clamps. The inner wall of each front clamp and the inner wall of each rear clamp are in contact with the outer surface of the steel frame. The steel frame has a channel steel inside. The upper surface of each front clamp and the upper surface of each rear clamp are in contact with the bottom surface of the channel steel. The bottom surface of each front clamp and the bottom surface of each rear clamp are fixedly connected to a fixing plate. Each set of fixing plates has two first bolts threaded inside, and the outer surface of each first bolt is threaded with a first nut. This utility model eliminates the need for welding when connecting the large-span steel structure transfer layer to the steel structure, reducing the danger of high-altitude welding for workers. It also facilitates fine-tuning of the installation error of the transfer layer and allows for quick disassembly and recycling of the transfer layer.

[0004] However, in actual use, the position of the upper end of the screw connecting to the channel steel is fixed, and the accuracy requirements for the position of the connecting holes on the surface of the hanging plate, screw and channel steel are high. When there is a certain deviation in the left and right position of the channel steel, the lower end of the screw cannot be fixed to the hanging plate. At this time, it is necessary to adjust the position of the channel steel or open a new connecting hole on the surface of the channel steel, which affects the installation efficiency.

[0005] Therefore, it is necessary to invent a connection structure between the steel structure transfer layer and the steel beam to solve the above problems. Utility Model Content
