Description

Technical Field

[0001] The present application relates to the technical field of earthquake-resistant components, and in particular to an earthquake-resistant device for beam-column nodes of reinforced concrete structures. Background Art

[0002] The beam-column node of reinforced concrete structure is a very critical part of the building structure. It refers to the connection area where the beam and column meet. In reinforced concrete structures, the design and construction of beam-column nodes directly affect the overall stability and safety of the structure. The reinforced concrete beam-column nodes in prefabricated concrete structures have the problem of insufficient fixation, resulting in poor seismic resistance. When encountering strong force fluctuations, the area where the reinforced concrete beam-column node is connected is easily damaged and easily broken, damaged or deformed, causing the overall seismic resistance to fail and leading to house collapse.

[0003] The existing announcement number is CN2467627Y, and the name is an anti-seismic device for a reinforced concrete structure beam-column node. It is composed of two reinforced steel plates symmetrically placed on both sides of the reinforced concrete structure beam-column node and firmly combined with the node into one; the shape of the two reinforced steel plates symmetrically placed on both sides of the reinforced concrete structure beam-column node is consistent with the shape of the node.

[0004] With respect to the above-mentioned related technologies, the inventors discovered that the above-mentioned method of ensuring the stability of the connection between the beam-column nodes of the reinforced concrete structure is to fix and assemble reinforced steel plates between the beam-column nodes of the reinforced concrete structure, and use the reinforced steel plates to increase the firmness of the connection between the beam-column nodes of the reinforced concrete structure. However, the vibration generated at the connection point of the beam-column node of the reinforced concrete structure lacks a filtering and absorption structure, resulting in a reduction in the stability of the connection between the beam-column nodes of the reinforced concrete structure. Utility Model Content
