Damper for beam column node of house

Abstract

The invention relates to a damper for a beam column node of a house. A first connecting plate is fixed on a beam of the house; a second connecting plate is fixed on a column of the house; one end of an outer arc-shaped plate is fixed with the first connecting plate; one end of an inner arc-shaped plate is fixed with the second connecting plate; an outer side plate is fixed on a side end face of the outer arc-shaped plate; an inner side plate is fixed on a side end face of the inner arc-shaped plate; the outer side plate and the inner side plate are located at two sides of the outer arc-shaped plate; a rotary assembly comprises a rotary shaft, a connecting steel plate and a plurality of rotary steel plates; the rotary shaft is mounted on the outer arc-shaped plate; one end of the connecting steel plate is connected with the rotary shaft; the plurality of rotary steel plates are arranged at the other end of the connecting steel plate; a sliding rotary shaft is mounted on the inner arc-shaped plate in a rotary manner; the connecting steel plate which slides relative to the sliding rotary shaft penetrates through the sliding rotary shaft; a rotary steel plate or a shearing steel plate is arranged between two viscoelastic material layers; the shearing steel plate is fixed with the second connecting plate. The damper provided by the invention has a good vibration absorption effect and belongs to the technical field of earthquake resistance of the houses.

Description

technical field [0001] The invention relates to the technical field of anti-seismic buildings, in particular to a damper used for beam-column joints of a building. 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 struct...

Problems solved by technology

[0003] At present, there are many energy-dissipating shock-absorbing devices, but no enlarged structure is designed in the energy-dissipating shock-absorbing devices to amplify the effect of shock-absorbing, and play a more obvious energy-dissipating and shock-absorbing effect under a small effect.
