Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure connection, and particularly relates to a connection node between a secondary beam and a main beam of a steel structure. Background Technique

[0002] In the construction of civil residences, office buildings and other buildings, steel structures are widely used because of their advantages such as high strength, light self-weight and fast construction speed.

[0003] The connection design between the main beam and the secondary beam of the steel structure should ensure clear and reasonable force transmission, simple production and convenient installation. The secondary beam and the main beam can be overlapped or flat-connected. Placing the secondary beam on the top surface of the main beam is an overlap connection. The overlap connection has a simple structure and convenient installation, but due to the large space height occupied by the main beam and the secondary beam, the connection stiffness is poor; placing the secondary beam on the side surface of the main beam is a flat connection. The top surface of the secondary beam and the top surface of the main beam are on the same plane. The space occupied by the main beam and the secondary beam is small, and the connection stiffness is good. Now it is widely used.

[0004] At present, most of the connection methods between the secondary beam and the main beam are flat connections. When the secondary beam and the main beam are connected, due to the large floor load in some building scenarios, it will cause great pressure on the secondary beam, and then it may cause the connection between the secondary beam and the main beam to break. Therefore, a connection node between a secondary beam and a main beam of a steel structure is needed, which can reinforce the connection between the secondary beam and the main beam through a reinforcement structure, avoid the breakage of the connection between the secondary beam and the main beam, and improve the stability of the connection between the secondary beam and the main beam.
