Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a connection structure between upper and lower columns and a steel beam for construction engineering. Background Art

[0002] The main function of the connection structure between the upper and lower columns and the steel beams used in construction projects is to transfer and bear loads. By tightly connecting the upper and lower columns and the steel beams, the strength and stability of the connection structure can effectively transfer the load from the beams to the columns to ensure the stability and safety of the entire building structure. Bolt connection is another commonly used connection method. The upper and lower columns and the steel beams are fixed together by bolts. This connection method requires pre-drilling holes in the columns and beams and then using bolts, washers and nuts to connect them. This connection method has the advantages of being detachable and adjustable, and is suitable for occasions that require flexible adjustment and maintenance.

[0003] After searching, the publication number CN216740901U disclosed a connection structure between upper and lower columns and steel beams for construction projects, comprising a main body, a disassembly mechanism provided on one side of the main body, a connecting rod provided on one side of the disassembly mechanism, a corrugated plate provided on the lower end of the main body, a plug provided on one side of the corrugated plate, and an anti-seismic device provided on the lower end of the corrugated plate. The utility model can quickly connect the beam and the column together through the joint action of the left mounting plate, the right mounting plate, the fixing hole, the groove and the fixing plate, and the installation process is relatively simple, saving time. Through the joint action of the reinforced steel plate, the screws, the rubber-plastic composite pad and the shock-absorbing pipe, the anti-seismic ability of the connection structure can be enhanced, making it difficult for it to form a gap or looseness between it and the beam and the column due to external force, and the rubber-plastic composite pad is provided because of its good elasticity to play a buffering role, making the connection structure not easy to be damaged.

[0004] In the above application, the seismic resistance of the connection structure can be enhanced by the combined action of reinforced steel plates, screws, rubber-plastic composite pads and shock-absorbing pipes, so that it is not easy for gaps or loosening to occur between it and the beams and columns due to external forces. The rubber-plastic composite pads can play a buffering role due to their good elasticity, making the connection structure less prone to damage. However, it does not take into account that punching may weaken the cross-sectional strength and rigidity of the steel beam. The connection method without punching can ensure the integrity of the steel beam and reduce the weakness of the structure. By avoiding punching the steel beam, its complete structural performance and load transfer capacity can be maintained. Utility Model Content
