Modified high damping composite rubber bearing

Abstract

The invention discloses a modified high-damping composite rubber bearing, which comprises an upper connecting plate, a lower connecting plate, a rubber laminated support assembly, and an energy-absorbing damping assembly. hole, the energy absorption damping component is installed inside the through hole, the upper connecting plate is installed on the upper end of the rubber laminated support component, and the lower connecting plate is installed on the lower end of the rubber laminated support component. laminate. In the present invention, mutually stacked rubber elastic columns are arranged between adjacent two groups of rubber laminates, so as to increase the elastic effect between the rubber laminates, improve the damping characteristics of the rubber support, and a limiting component is arranged between the laminate plates , through the limiting effect between the upper limit column and the lower limit column, the rubber is prevented from being damaged due to excessive extrusion, and a spring is arranged between the upper limit column and the lower limit column to further enhance the elastic effect between the laminated plates, thereby Improved damping characteristics of rubber mounts.

Description

Modified high damping composite rubber bearing technical field [0001] The present invention relates to the technical field of rubber bearings, in particular to a modified high-damping composite rubber bearing. Background technique At present, the supports for bridges and buildings are generally made of natural rubber, and the supports with high damping generally use lead. Core rubber bearings, that is, adding one or more lead cores inside the natural rubber bearings; however, although the damping of lead rubber bearings High, good protection effect, but because lead is a heavy metal, it will cause pollution to the environment during the use process, and it will affect the workers in the production process. It is harmful to human health and does not meet the requirements of green environmental protection; and its self-recovery ability is weak and the isolation frequency band is narrow, while natural rubber The bearing made of rubber is prone to large deformation when ...

[0002] At present, bearings for bridges and buildings are generally made of natural rubber, and bearings with high damping generally use lead core rubber bearings, that is, one or more lead cores are added inside the natural rubber bearing; however, although lead The core rubber bearing has high damping and good protection effect, but because lead is a heavy metal, it will pollute the environment during use and bring harm to the health of workers during the production process, which does not meet the requirements of green environmental protection; and its self-recovery ability Weaker, narrow vibration isolation frequency band, and the bearing made of natural rubber is prone to large deformation when it is subjected to excessive impact force from the outside, making the rubber deformed excessively and damaged
