High-damping vibration-reduction rubber bearing for bridge

Abstract

The invention discloses a high-damping vibration-reduction rubber bearing for a bridge. The high-damping vibration-reduction rubber bearing comprises a rubber block, the upper surface of the rubber block is fixedly connected with an upper connection plate, and the upper surface of the upper connection plate is in lapped connection with the lower surface on an upper pre-buried plate. According to the high-damping vibration-reduction rubber bearing for the bridge, by arranging supporting rods, rolling wheels, trapezoidal blocks, sliding devices and elastic devices, vibration of the bridge drivesthe two supporting rods and the two rolling wheels to move downwards through the upper pre-buried plate and the upper connection plate, and under pressure, first springs can generate elastic force soas to reduce vibration of the upper pre-buried plate; by arranging vibration-reduction devices, under pressure, second springs can generate elastic force so as to reduce vibration of the upper connection plate. In this way, vibration of the pre-buried plate is reduced through multiple structures, the vibration-reduction ability of the upper pre-buried plate is improved, the damage to the rubber block can be reduced, and the service life of the rubber block is ensured.

Description

technical field [0001] The invention relates to the technical field of bridge damping, in particular to a high-damping rubber bridge damping bearing. Background technique [0002] High-damping shock-isolation rubber bearing, which is made by adding various compounding agents to natural rubber to improve the damping performance of rubber (increasing hysteresis loss and reducing its storage modulus), and then using this rubber with damping effect It is a laminated product of steel plate and rubber formed by thermal vulcanization, which is similar to the structure of ordinary rubber bearings. [0003] The high-damping and shock-isolating rubber seat has a wide range of applications, and is a new type of bridge and building construction product with high cost performance. However, the existing high-damping and shock-isolating rubber seat is relatively simple in terms of shock absorption. The bridge is isolated by the rubber block, and the rubber block is easy to reduce the serv...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-damping rubber bridge shock-absorbing support, which solves the problem that the existing high-damping shock-isolating rubber seat is relatively simple in terms of shock absorption. When the bridge vibrates, the product can only rely on The rubber block is used for vibration isolation of the bridge. At the same time, the rubber block is easy to reduce the service life of the rubber block under the long-term vibration of the bridge.
