Shock insulation rubber support

Abstract

The invention discloses a shock insulation rubber support, which is composed of rubber layers, stiffening steel plates, a protective rubber layer, seal coat steel plates and a support connecting steelplate, wherein a laminated rubber body filled with the rubber layers and the stiffening steel plates alternately is arranged in a cylindrical space defined by the protective rubber layer, the upper end and the lower end of the laminated rubber body are respectively provided with the seal coat steel plates for sealing the two ends of the protective rubber layer, the plurality of rubber layers arecombined in a specific arrangement mode, and the specific arrangement mode is one of a sequential arrangement mode, an alternate arrangement mode or a symmetrical arrangement mode; different rubber materials are adopted, the functions of vibration reduction, high damping, shearing resistance, high bearing capacity and the like are respectively realized by the rubber layers; the rubber layers are used in cooperation to realize performance coordination of the whole support, the elasticity and damping performance can be achieved at the same time, and the coordination of vertical bearing performance and horizontal shearing performance can also be guaranteed. Meanwhile, the shock insulation rubber support has multiple damping peaks, and it is guaranteed that the support has good environmental adaptability and durability.

Description

technical field [0001] The invention relates to a rubber bearing, in particular to a shock-isolation rubber bearing. Background technique [0002] Isolation rubber bearings are rubber bearings used for seismic isolation of houses, bridges or other structures in earthquake areas, including natural rubber bearings (LNR), lead rubber bearings (LRB) and high damping rubber bearings (HDR) , the main structure is integrally vulcanized by laminated rubber and stiffened steel plates. The upper and lower structures are connected by sealing steel plates and connecting steel plates, which can effectively reduce the effect of structural seismic force. It has been applied in many engineering projects in recent years. [0003] The vibration-isolation rubber bearing needs to have good vertical bearing capacity, horizontal shear performance, self-resetting performance and damping energy dissipation characteristics, as well as good environmental adaptability and durability. In order to achi...

AI Technical Summary

Problems solved by technology

The higher the damping of the rubber material, the greater the energy consumption and the greater the heat generation, which will cause the molecular chain to break and accelerate the aging of the rubber, and the durability is poor; reducing the damping and improving the elasticity of the rubber material can improve the reset performance of the bearing and reduce permanent deformation, but Will not be able to guarantee energy consumption and shock isolation effect

[0005] (2) Insufficient temperature adaptability of a single rubber material

However, as a result of such modification, the overall properties of the rubber material, especially the mechanical properties, will often be reduced.

This is because when two or more types of rubber are blended and modified, the vulcanization time, vulcanization speed and vulcanization degree cannot be well matched when different materials are co-vulcanized, so there are few practical applications.

[0006] (3) The same kind of rubber has insufficient adaptability when meeting the vertical load-bearing and horizontal shear properties
