Damper for beam-column joints of house

Abstract

The invention provides a damper for beam-column joints of a house. The damper comprises a first friction assembly, a second friction assembly, a first bracket assembly, and a second bracket assembly;the first bracket assembly is used for connecting the first friction assembly to the beam-column joints of the house, and the second bracket assembly is used for connecting the second friction assembly to the beam-column joints of the house; the first friction assembly includes at least two first friction plates disposed in an overlapping mode and a first connecting portion fixedly connected to the friction plates; the second friction assembly comprises at least two second friction plates disposed in an overlapping manner and a second connecting portion fixedly connected to the second frictionplates; and the first friction plates are interdigitated with the second friction plates, and the first connecting portion and the second connecting portion are connected in a hinged mode, so that the first friction plates and the second friction plates have a degree of freedom of rotation relative to an axis. The damper for beam-column joints of the house is simple in structure, small in occupied space, and obvious in shock absorption effect.

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] Additional dampers at joints can effectively improve the seismic performance of prefabricated concrete structure joints. At present, the dampers at joints commonly used in structural engineering occupy a small space, but the displacement of the beam-column joints where they are installed is small, thus limiting The energy dissipation performance of the damper is improved; and for the displacement amplifier damper support, such as toggle-type amplified support, scissor-type transmission amplified support, cable-damper support, etc., the installation space of these forms of damper is large and the technology Complicated, etc., inconvenient to apply to nodes
