Problems solved by technology

[0007] Under the action of external force, earthquake or wind load, the relative rotation angle or displacement between the beam-column joints of the building is small, and the existing dampers installed at the joint positions require a large relative deformation of the structure to fully achieve the energy dissipation effect , so it is often limited in practical applications

Abstract

The invention provides a gear transmission amplified type joint shearing damper. Relatively small rotary angles generated at beam-column joints of a fabricated building structure under the external load effect can be amplified according to needs; through displacement limiting of the amplified rotary angles, the energy-consumption capacity of a viscoelastic material in the damper is sufficiently exerted, and therefore an ideal energy-consumption effect is achieved, that is, when the relative rotary angles are generated at the beam-column joints of the building structure, the rotary angles are amplified through a gear transmission mechanism and then transmitted to a rotary disc, and when the rotary disc rotates, the viscoelastic material is driven to be subjected to shearing hysteretic deformation so that energy can be consumed. According to the gear transmission amplified type joint shearing damper, the rotary angle magnification times can be adjusted according to the practical condition of the building structure or building components, installation is easy, and the amplified joint shearing damper is a flexible and efficient energy-consumption element.

Description

technical field [0001] The invention provides a gear-driven amplified node shear damper, which is installed at the beam-column node of a prefabricated building structure, and can adjust the smaller relative rotation angle generated at the beam-column node under the action of an external load as required. Amplification, by limiting the enlarged rotation angle, the energy dissipation capacity of the viscoelastic shear material in the damper is fully utilized to consume seismic energy. Background technique [0002] The energy-dissipating and shock-absorbing technology of the structure is to install energy-dissipating devices in some parts of the structure, and dissipate or absorb the energy input into the structure by external force, earthquake action or wind load through the hysteretic deformation of the energy-dissipating device, so as to reduce the The seismic response of the main structure is small, so as to avoid structure damage or collapse, and achieve the purpose of sho...
