Recycled concrete shearing vibration isolation device

Abstract

The invention relates to a recycled concrete shearing vibration isolation device. The recycled concrete shearing vibration isolation device comprises a shearing vibration isolation box body, a vibration isolation block and a lateral vibration isolation spring, wherein the vibration isolation block and the lateral vibration isolation spring are arranged in the shearing vibration isolation box body; wherein the top side and the bottom side of the vibration isolation block are in frictional contact with the inner wall of the top side and the inner wall of the bottom side of the shearing vibration isolation box body respectively; the lateral vibration isolation springs are arranged on the periphery of the vibration isolation block, and the two ends of each lateral vibration isolation spring are connected with the side wall of the vibration isolation block and the inner side wall of the constraint box body. Compared with the prior art, the coarse surface of the recycled concrete is utilized inside, so that the influence of an earthquake is isolated through friction of an interface during the earthquake, and meanwhile, the anti-cracking performance of the recycled concrete is improved through the steel fibers arranged inside the recycled concrete; meanwhile, the friction performance between the concrete surfaces is further improved through the steel fibers on the surfaces of the recycled concrete, the overall vibration isolation performance of the device is guaranteed, and good application prospects are achieved in the aspect of building structure vibration isolation.

Description

technical field [0001] The invention belongs to the technical field of building vibration isolation, and relates to a recycled concrete shear vibration isolation device. Background technique [0002] The building structure is prone to damage or large deformation under earthquake or wind vibration, which affects normal use. The conventional treatment method generally adopts the installation of damping devices in the building structure to change the vibration period of the structure and consume vibration. However, due to the complex structure of the damper, The price is high, and it can only be used in some super high-rise and important building structures. [0003] Building seismic isolation technology, the base of the building or a certain position is installed with a seismic isolation device to form a seismic isolation layer, which isolates the upper structure from the lower foundation, so as to consume seismic energy and avoid or reduce the transmission of seismic energy t...
