Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a steel structure cantilever beam connection node. Background Technology

[0002] In the current construction industry, steel structures are widely used due to their advantages such as high strength, fast construction speed, and recyclability. As a common component in steel structures, the design and construction of the connection nodes of cantilever beams are crucial to the stability and safety of the entire structure. Therefore, developing a steel structure cantilever beam connection node is particularly important.

[0003] Referring to the steel structure cantilever beam-column connection node structure with reference announcement number CN219431040U, it includes a steel structure column, a structural beam assembly, an installation assembly, and a stabilizing assembly. The structural beam assembly includes a steel structure beam, and the installation assembly includes an overlapping top plate. The lower end of the overlapping top plate is connected to a positioning bottom plate, and the end of the positioning bottom plate away from the overlapping top plate is connected to another overlapping bottom plate. After the overlapping bottom plate and the steel structure column are installed and connected, the support plate is located at the lower end of the positioning bottom plate. Through the setting of the support plate, the steel structure can be stabilized. The pressure on the cantilever beam is transferred to the steel column, thereby reducing the pressure on the steel beam and improving its compressive and bending strength. At the same time, the support plate increases the connection area between the steel beam and the steel column, improving the stability of the connection. As can be seen from the above, although this cantilever beam connection node can be well applied, it is usually not convenient to reinforce the main beam components of two adjacent cantilever beams, making it difficult for the structural strength between adjacent beams to reach the expected level, which often troubles users.
