High-damp rubber supporting seat compositing high-strength fine steel wire mesh with reinforced steel fibers

Abstract

The invention relates to a high-damp rubber supporting seat compositing a high-strength fine steel wire mesh with reinforced steel fibers. The supporting seat is characterized in that a steel plate at the inner part of the existing high-damp supporting seat is replaced with a fine steel wire mesh which consists of high-strength steel wires staggered perpendicularly, and the supporting seat consists of an upper connecting steel plate, a lower connecting steel plate, an upper closing plate, a lower closing plate, a high-damp rubber layer, a high-strength fine steel wire mesh layer and an external rubber protective layer. According to the rubber supporting seat, the high-strength fine steel wire mesh is adopted for replacing a reinforced steel plate with a thicker thickness, so that the shearing deforming capability of the high-damp rubber supporting seat can be increased, the bonding effect of rubber and the steel wire mesh is enlarged, and at the same time, the whole weight of the supporting seat is lightened. The high-strength fine steel wire mesh can be bent, adaptability to the shearing deforming and the corner deformation of the supporting seat is stronger, and in addition, larger shearing deformation can make full use of the capabilities of hysteresis and energy consumption of high damp; under the action of earthquakes with different frequencies, the rubber supporting seat disclosed by the invention can realize the effective protection for engineering structures.

Description

technical field [0001] The invention belongs to the technical fields of civil engineering and earthquake engineering, and in particular relates to a novel composite high-damping rubber bearing, in particular to a high-strength fine steel mesh reinforced steel fiber composite high-damping rubber bearing. Background technique [0002] In recent years, earthquake disasters have occurred frequently in our country, especially the Wenchuan earthquake in Sichuan has caused serious damage to buildings, bridges and other structures. On the basis of summarizing the experience and lessons of earthquake damage, the concept of seismic isolation design has gradually penetrated into the design thinking of structural engineers along with the revision of various seismic design codes. Among them, various vibration-absorbing and isolating bearings, including high-damping rubber bearings, have gradually been widely used in the design of bridge structures. [0003] At present, the high-damping ...
