Description

Technical Field

[0001] The utility model relates to the technical field of steel structure assembly, in particular to a connection structure of a steel structure. Background Art

[0002] In construction projects, steel structures are widely used due to their high strength, good earthquake resistance and easy manufacturing. However, the connection between steel structures has always been a key issue that engineers need to face. Traditional steel structure connection methods, such as welding and bolting, although they meet engineering needs to a certain extent, are difficult to disassemble after the connection is completed. Because they cannot be disassembled in time, once the steel structure needs to be disassembled, it is very troublesome, thereby reducing the work efficiency of the operator.

[0003] A Chinese patent discloses a connection mechanism for a steel structure (authorization announcement number CN219196304U). The patented technology can align the fixing block on the second connection block with the installation slot on the first connection block by setting a fixing piece. After the alignment is completed, the user pushes the fixing piece forward to insert it into the installation slot. During the insertion process, the buckle on the second connection block will also be inserted into the slot. When the fixing piece is inserted into the installation slot, the elastic force of the spring will bounce the fixing piece into the installation port, thereby completing the connection between the first steel structure and the second steel structure of the fixed pipe, thereby achieving the effect of connecting the steel structure;

[0004] However, it has certain disadvantages: the two steel structures are connected by fixings stuck in the installation opening, and the radial bearing force is borne by the fixing blocks and buckles, while the axial tension is only borne by the fixings, and the reliability is low. Once the fixings are worn or under pressure, the fixings are removed from the installation opening, and the connection firmness of the two steel structures will be affected. Utility Model Content

The positioning block on one steel structure is slid into the positioning groove on the other steel structure, and then the insertion rod is inserted into the positioning seat and the positioning block.
