Anti-pull high damping rubber shock-isolation bearing

Abstract

An anti-pullhigh damping rubber vibration isolating support belongs to the technical field of vibration isolating supports. The vibration isolating support is constituted of upper and lower connecting plates, upper and lower seal plates, a high damping rubber support body, an anti-pull connecting body and bolts, wherein the bolts are connected between the upper and lower connecting plates and the upper and lower seal plates; the middle portion of the anti-pull connecting body is in contact with but not connected to the upper and lower seal plates; and the contact surface is smeared with polytetrafluoroethylene for realizing free slide at the horizontal direction. The anti-pull high damping rubber vibration isolating support is suitable for the requirement of a building structure to deform under the effect of normal load; the self rigidity and damping property of the anti-pull high damping rubber vibration isolating support can meet the requirement of different vibration-resisting performances; especially, in rarely met earthquakes, the support provided herein has anti-pull performance, thus the support can resist the vertical pull force; and the support structure has the advantages of simple structure, strong bearing capacity at the vertical direction, large horizontal displacement, good durability and strong capacity to resist pull force, thus the support is suitable for buildings with high requirement to high anti-pull performance at the vertical direction.

Description

technical field [0001] The invention relates to a shock-absorbing and isolating support device for bridges, buildings and other structures, in particular to a shock-isolating support requiring pullout resistance, and belongs to the technical field of shock-isolating supports. Background technique [0002] When building bridges, buildings, and other large structures in earthquake areas, in order to reduce the potential earthquake threat, it is necessary to carry out seismic design for such structures. Among them, adopting seismic isolation design is one of the effective ways to reduce the earthquake damage of structures. Seismic isolation technology is to place the entire upper structure on a less rigid seismic isolation layer. The seismic isolation layer has sufficient vertical stiffness and vertical bearing capacity, can stably support the building, and can reduce the transmission of seismic energy to the upper part. And it has enough flexible horizontal stiffness to ensure...
