Bridge shock insulation support

Abstract

The invention discloses a bridge shock insulation support. The bridge shock insulation support comprises an upper connecting plate, a seat plate, a lower connecting plate, laminated rubber and a damping core, the upper connecting plate is connected with a bridge floor; the lower connecting plate is connected with a pier; the laminated rubber is fixed between the seat plate and the lower connectingplate; the damping core is embedded in the center of the laminated rubber, a hollow pipe extending spirally is fixed to the seat plate, the upper end of the hollow pipe is fixed to the lower side face of the upper connecting plate, the lower end of the hollow pipe is fixed to the upper side face of the base, and the hollow pipe is filled with filler. According to the bridge shock insulation support, through the arrangement of the hollow pipe, the upper connecting plate can be folded up in the transportation and installation process, and then the effect of isolating vertical vibration is achieved in the mode of injecting filler after installation is completed.

Description

technical field [0001] The invention relates to a shock-isolation support, more specifically to a bridge shock-isolation support. Background technique [0002] Seismic isolation bearings are currently widely used in existing building structures, such as houses, bridges and other places. At present, rubber seismic isolation bearings are more commonly used. Through the elastic effect of rubber, the horizontal vibration can be reduced. At the same time It can also ensure sufficient vertical loads to support buildings built on seismically isolated bearings. [0003] However, in the process of using the existing rubber shock-isolating bearing, because the energy consumption of the rubber is not good enough, a lead core will be added in the center of the rubber shock-isolating bearing to increase the energy consumption through the lead core. However, lead The setting of the core, due to the pollution of lead to the environment and the damage to human health, it is necessary to de...

[0003] However, in the process of using the existing rubber shock-isolating bearing, because the energy consumption of the rubber is not good enough, a lead core will be added in the center of the rubber shock-isolating bearing to increase the energy consumption through the lead core. However, lead The setting of the core, due to the pollution of lead to the environment and the damage to human health, it is necessary to develop its substitutes. At the same time, the vibration isolation in the middle of the existing vibration isolation support is a combination of rubber and steel plates, so it cannot be used. The vibration in the vertical direction is absorbed and isolated. Therefore, in the prior art, an elastic liftable top plate is set above the upper connecting plate to achieve the vibration isolation effect in the vertical direction. However, the structure of this structure The vibration isolation support, because when performing vertical vibration isolation, it is necessary to give the roof a sufficient lifting space, so the vibration isolation support of this structure will cause the overall height to be too high, which will make transportation and installation difficult.
