Description

Technical Field

[0001] The utility model belongs to the technical field of steel beam connection, in particular to a connection node for steel beam frame assembly. Background Art

[0002] The steel frame of a steel structure can be used to form the skeleton frame of a building, which is usually composed of vertical columns and horizontal beams, which are riveted, bolted or welded in a rectilinear grid. The steel beams are horizontal structural members that can withstand loads applied laterally to their axes, while the steel columns are vertical structural members that transmit compressive loads. The combined connection parts of steel beams and steel columns are generally called connection nodes.

[0003] Based on the above, the inventors have found that the existing connection nodes for steel beam frame assemblies have the following deficiencies:

[0004] 1. Most of the force on the steel beam acts on the connecting parts, resulting in poor force-bearing capacity of the combined connection part of the steel beam and the steel column. It is not convenient to open an insertion structure on the steel column to insert the steel beam to enhance the force-bearing capacity;

[0005] 2. After the steel beam is inserted into the steel column, it is fixed by only one structural form, which may easily cause the steel beam to fall out of the steel column. It is not convenient to install fixed structures inside and outside the steel column at the same time to fix the inserted steel beam. Utility Model Content
