Joint amplification damper

Abstract

The invention relates to a joint amplification damper. The joint amplification damper comprising a first support, a first connecting rod, a second connecting rod, a second support, a third connectingrod, a fourth connecting rod, multiple first shearing steel plates, multiple second shearing steel plates, multiple third shearing steel plates and multiple fourth shearing steel plates. The first connecting rod and the second connecting rod are rotatably mounted on the first support, the third connecting rod and the fourth connecting rod are rotatably mounted on the second support, the first shearing steel plates are integrally formed with the first connecting rod, the second shearing steel plates are integrally formed with the second connecting rod, the third shearing steel plates are integrally formed with the third connecting rod, and the fourth shearing steel plates are integrally formed with the fourth connecting rod. The first shearing steel plates and the second shearing steel plates are alternately arranged in sequence, the third shearing steel plates and the fourth shearing steel plates are alternately arranged in sequence, a damping material layer is disposed between the first shearing steel plates and the second shearing steel plates, a damping material layer is disposed between the third shearing steel plates and the fourth shearing steel plates, the first connecting rod and the fourth connecting rod are rotatably connected together, and the second connecting rod and the third connecting rod are rotatably connected together. The joint amplification damper has goodshock absorption effect and belongs to the technical field of earthquake resistance of houses.

Description

technical field [0001] The invention relates to the technical field of anti-seismic buildings, in particular to a node amplification damper. Background technique [0002] In recent years, my country has done a lot of research work on the isolation, vibration reduction and vibration control of engineering structures, and achieved fruitful research results. Traditional anti-seismic designers resist earthquakes by enhancing the anti-seismic performance of the structure itself, that is, using the structure itself to store and consume seismic energy to meet the anti-seismic fortification standards of the structure: small earthquakes are not damaged, moderate earthquakes can be repaired, and large earthquakes cannot collapse. However, this anti-seismic method lacks self-regulation ability, and may not meet the safety requirements under uncertain earthquake action. The structural vibration control technology provides a reasonable and effective way for structures to resist earthqua...

Problems solved by technology

[0003] In prefabricated concrete structures, the joints of prefabricated beams and prefabricated columns are the joints, and adding dampers at the joints can effectively improve the seismic performance of prefabricated concrete structure joints, but the current dampers have a large installation space and complex technology etc., inconveniently applied to nodes
