Description

Technical Field

[0001] The utility model relates to the technical field of steel structure buildings, in particular to a shock absorbing device for a beam-column node. Background Art

[0002] The beam-column joint is a very important connection part in the building structure. It is responsible for effectively transmitting and distributing the forces between the beams and columns to ensure the overall stability and safety of the structure. The semi-rigid node in the beam-column joint is between the rigid node and the hinged node. It can partially transmit bending moment and shear force, and has the advantages of both rigid and hinged nodes with high flexibility.

[0003] The existing announcement number is CN211285970U, and its name is an energy-absorbing and shock-absorbing beam-column node structure for prefabricated buildings. It is characterized in that: the beam-column node structure includes prefabricated beams and prefabricated columns, and a friction material layer is tightly fitted on the top of the prefabricated column. One end of the prefabricated beam is flatly installed on the friction material layer on the top of the corresponding prefabricated column. A flexible connection is adopted between the prefabricated beams and prefabricated columns to allow the interconnected prefabricated beams and prefabricated columns to be displaced or rotated. The beams and columns are flexibly connected by bolts combined with longitudinal steel bars and nuts, and a layer of friction material is added between the beams and columns. The flexible connection allows the interconnected components to be displaced or rotated, and does not restrict the deformation of the beams and columns.

[0004] However, the above-mentioned beam-column node lacks shock-absorbing connecting components during assembly. When the beam-column node is subjected to vibration, the connection point of the beam-column node is easily offset due to the vibration, resulting in a loose connection of the beam-column node, which affects the overall seismic stability of the beam-column node.
