Abstract

The invention discloses a rubber shock-absorbing and isolation system for high-rise buildings; it includes a main shock-absorbing body, an upper connecting plate and a lower connecting plate; the inside of the main shock-absorbing body is provided with a rubber layer and a steel plate layer, and the The rubber layer and the steel plate layer are superimposed on each other in sequence; the middle position of the rubber layer and the steel plate layer is provided with a lead core; the top and bottom of the main shock absorber are connected with sealing plates, and the top and bottom of the lead core are Connected with the sealing plate; the outer peripheral side of the shock-absorbing main body is evenly provided with a plurality of auxiliary shock-absorbing bodies; by setting the main shock-absorbing body, a bent and superimposed rubber layer and a steel plate layer are arranged, and when subjected to transverse or longitudinal deformation, The rubber sheet is deformed and sheared to provide certain damping and stiffness; by setting the auxiliary shock-isolator, the pressure signal is received through the pressure sensor and transmitted to the control unit to change the strength of the magnetic field, so that the damping of the electromagnetic fluid changes with the strength of the magnetic field And change; better shock absorption.

Description

technical field [0001] The invention belongs to the field of building shock-isolation technology, in particular to a rubber shock-absorbing and shock-isolation system for high-rise buildings. Background technique [0002] Seismic isolation technology is a newly developed anti-seismic technology in recent years. Its core device is the building isolation rubber bearing. The main purpose is to prolong the service life of the building structure. When an earthquake occurs, the vibration-isolated rubber bearing bears the deformation of the main structure of the building, reduces the upward transfer rate of energy, and reduces the seismic acceleration response of the upper structure to 1 / 4-1 / 8 of that of the non-seismic isolation, making the building structure close to Based on the overall horizontal movement, it plays a role of "isolation" for earthquakes; according to the basic structure of building isolation rubber bearings, in view of the current development status of building i...
