Description

Technical Field

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

[0002] The connection structure of steel beams mainly includes three forms: welding, bolting and riveting. Welding is to use the heat generated by the arc to partially melt the welding rod and the weldment, and form a weld after cooling, so as to connect the components into one. The advantages of welding are that it does not weaken the cross section of the component, the material is economical, the structure is simple, and the connection stiffness is large and the sealing performance is good. However, the disadvantage is that a heat-affected zone will be formed near the weld, causing the material to become locally brittle, and residual stress and deformation may be generated. Bolting is to use high-strength bolts for connection. This method is easy to install and position, and the construction is convenient, which conforms to the industrialized production model. Although the full bolt connection is more expensive, the joint size is larger, the amount of steel used is slightly more, and the joint may slip during a strong earthquake. Riveting is to use rivets to connect two or more components together, but due to the development of welding and high-strength bolt connections, this connection method is rarely used at present.

[0003] Chinese patent CN218757933U discloses a steel beam connection structure. The utility model sets the vertical beam on the guide block, so that the vertical beam is connected through the installation piece under the action of the guide block and the installation block, so as to facilitate the connection between the vertical beam and the base, enhance the stability between the vertical beam connection port and the base, and use the installation piece to facilitate the installation and disassembly of the vertical beam and the base, reduce the use of nuts, and reduce the workload of steel structure connection. Although this structure can reduce the workload during connection, the connection method between the vertical beam and the base requires manual assistance to keep the vertical beam in a vertical state during installation, which brings difficulties to construction and reduces the problem of work efficiency. Therefore, this utility model is proposed to solve the above problems. Utility Model Content
