Problems solved by technology
However, lead-core rubber bearings and high-damping rubber bearings have problems such as heavy metal pollution, low horizontal stiffness, and performance degradation during service; friction pendulum bearings have problems such as difficult to control friction and vertical displacement when swinging.
In addition, these traditional shock-absorbing and isolating bearings do not have the function of pull-out resistance, and some additional structures are needed to achieve the effect of pull-out resistance

Abstract
The invention discloses a grid damping support, which comprises a grid damper, an elastic support body, a top plate and a bottom plate; the grid damper is a hollow shell with openings at both ends, and the shell is made of steel; the shell A plurality of weakening holes are opened on the body; the elastic support body is embedded in the housing of the grid damper; the lower port of the housing is arranged on the bottom plate and is fixedly connected with the bottom plate, and the lower end surface of the elastic support body is in contact with the bottom plate. The upper surface of the bottom plate is in contact; the upper port of the housing is fixedly connected with the top plate, and the upper end surface of the elastic support body is in contact with the lower panel of the top plate. The beneficial effect of the present invention is: the present invention utilizes the high ductility of low-yield steel, and weakens the hole by setting a certain number and shape of weakened holes on the low-yield steel to make the steel grid damper, by combining this damper with the elastic support A new type of shock-absorbing and isolating support is made by combining the body, which has a strong energy dissipation capacity and has a shock-absorbing effect in both horizontal directions.
Description
A grille damping support technical field The present invention relates to bridge engineering, construction engineering damping field, be specifically related to a kind of grille damping bearing. Background technique [0002] Buildings and bridges, as important public building structures, play an important role in national production and life. In order to protect it from earthquake damage, in practical engineering, the method of installing seismic isolation devices is generally used to improve the structure's resistance. shock ability. At present, in bridges and building structures, shock-absorbing and isolating bearings are often used for shock absorption, and traditional shock-absorbing and isolating bearings include Lead core rubber bearings, friction pendulum bearings, high damping rubber bearings and other types. But lead core rubber bearings and high damping rubber The bearing has the problems of heavy metal pollution, low horizontal stiffness and performance d...
