Composite damping rubber vibration reducing bearing

Abstract

The invention relates to a composite damping rubber shock-absorbing bearing. It is composed of high-strength fine steel wire mesh, high damping rubber layer, upper sealing plate, fine soft steel rod, multi-graded mixed filling material and lower sealing plate. The multi-graded mixed filling material is mixed with fine particle damping material and fine rubber elastic sphere Composition: The upper end of the thin soft steel rod is fixed on the upper sealing plate and embedded in the multi-graded mixed filler; the high-strength fine-density steel wire mesh and the high-damping rubber layer reserve holes for filling the multi-graded mixed filler. In the damping system described in the present invention, each component can give full play to its own advantages, and realize the organic combination of functions between the components, so that the composite damping rubber shock-absorbing bearing has ultra-high damping performance, so there is no need to configure such as dampers, etc. Other auxiliary shock-absorbing equipment can greatly reduce engineering cost investment and reduce the difficulty of design and construction. The invention has the characteristics of high performance, low carbon and environmental protection, reasonable economy, convenient maintenance and the like, and has broad application prospects.

Description

technical field [0001] The invention belongs to the technical fields of civil engineering and earthquake engineering, and in particular relates to a composite damping rubber damping support with a composite damping system. Background technique [0002] At present, plate rubber bearings are widely used in medium and small span bridges because of their simple structure, low cost and convenient installation. However, due to its low damping ratio (about 2% to 4%) and low energy dissipation capacity of the plate rubber bearing, it is necessary to optimize its performance, especially to improve the damping performance and enhance the energy dissipation capacity. [0003] At present, the existing products on the market are mainly to improve the damping performance of ordinary plate rubber bearings by optimizing some components. Specifically, there are two main ideas. One is to directly optimize the mechanical properties of a component in the bearing, using high-performance materia...
