Description

Technical Field

[0001] The utility model relates to the technical field of connection of prefabricated steel structure joints, and specifically relates to a connection structure of prefabricated steel structure joints. Background Technique

[0002] A steel structure is a structure composed of steel materials, mainly applied in the construction industry. Due to the advantages of high strength, light weight, and strong resistance to deformation of steel, it is very suitable for the needs of construction. Common steel structures in the construction industry include steel plates, steel columns, steel pipes, etc. Steel pipes are often used in the construction industry, and the lengths of steel pipes vary. When in use, two or more steel pipes are often connected.

[0003] For example, in the utility model patent with the publication number of CN215483605U, a connection structure of prefabricated steel structure joints is disclosed, which relates to the technical field of steel structures; it includes steel pipes. There are two steel pipes, and a connecting piece is sleeved between the steel pipes. The inside of the connecting piece is hollow. At the upper and lower ends of the side of the connecting piece, there are both abutting blocks that can move and abut against the inner wall of the steel pipe. At the upper end of the connecting piece, there is a disc that can rotate to drive the abutting blocks to move, and at the upper end of the disc, there is a limit screw that can rotate to limit the disc.

[0004] However, when this utility model is in use, the abutting blocks move on the screw rod and contact the inner wall of the steel pipe and are connected and fixed through friction. However, only being connected and fixed through friction has a poor fixing effect. When the steel pipe is stressed, it is easy to loosen and break away from the connection, which has potential safety hazards and poor use effects. Content of the Utility Model
