CN201495487U - Vibration isolation rubber bearing - Google Patents

Abstract

The utility model relates to a vibration isolation rubber bearing applied to bridges and house buildings, which comprises a rubber body, an upper seal plate and a lower seal plate, wherein the upper seal plate and the lower seal plate are respectively embedded in the upper end surface and the lower end surface of the rubber body. The vibration isolation rubber bearing is characterized by having a plurality of high strength warp and weft isotropic cloth layers arranged at intervals between the upper seal plate and the lower seal plate. The vibration isolation rubber bearing replaces a steel plate with the high strength warp and weft isotropic cloth which basically achieves the strength of the steel plate, but has much lower rigidity and lighter weight than those of the steel plate, and has relatively larger elastic deformation capacity. Compared with a vibration isolation rubber bearing employing the complete steel plate which has relatively high rigidity, the vibration isolation rubber bearing has transversal force which is easier to be dispersed, and elasticity which is better and more stable, thereby the longitudinal rigidity and horizontal rigidity are more easily controlled and adjusted, force loading is evener in working process, and accordingly service lives of products and buildings can be obviously prolonged. The vibration isolation rubber bearing has the advantages of excellent performance, simple structure, convenient processing, low manufacturing cost and the like.

Description

Shock insulation rubber bearing

Technical field

The utility model relates to a kind of bridge and employed shock insulation rubber bearing of building construction of being arranged on.

Background technology

General shock insulation rubber bearing all is to form according to form coefficient and designing requirement production and processing with rubber and steel plate lamination.Rubber and steel plate lamination production technology forms vertical rigidity easily and horizontal rigidity is too high has reduced the product shock-absorbing capacity, has reduced the horizontal dispersion force of product, has influenced the functional performance of product, has also influenced the application life of product.

The utility model content

The utility model provides a kind of when satisfying the vertical direction cushioning effect at above problem, can also carry the shock insulation rubber bearing of big load level dispersion force.

The technical solution of the utility model is: comprise rubber body and the upper and lower shrouding that is entrenched in the body upper and lower end face, be arranged at intervals with several layers high strength warp-weft same-nature layer of cloth between the described upper and lower shrouding.

The utility model adopts the high strength warp-weft same-nature fabric to replace steel plate.It reaches the intensity of steel plate substantially, but rigidity and weight is well below steel plate, and has stronger elastic deformability, when running into cross shear, can with the elastomeric material acting in conjunction, so since high strength cloth be that warp-weft same-nature can be absorbed in bearing inside everywhere with shearing force equably.The shock isolating pedestal of whole steel sheet, the rigidity of steel plate is too high, the easier branch of shock insulation rubber bearing horizontal force of the present utility model by contrast, elasticity is than using the better more stable of whole steel sheet, so vertical rigidity and easier grasp of horizontal rigidity and adjustment, stressed in the course of the work more even, can significantly improve product and building and adapt to the life-span.The utlity model has excellent performance, simple structure, remarkable advantage such as easy to process, with low cost.

Description of drawings

Fig. 1 is a structural representation of the present utility model

1 is shrouding among the figure, the 2nd, and body, the 3rd, high strength warp-weft same-nature layer of cloth.

Fig. 2 is the vertical view of Fig. 1

The specific embodiment

The utility model is as shown in Figure 1, 2: comprise that the cross section is the rubber body 2 of circular (or other geometries such as ellipse, square, rectangle) and is entrenched in upper and lower shrouding 1 in body 2 upper and lower end faces, is arranged at intervals with several layers high strength warp-weft same-nature layer of cloth 3 between the upper and lower shrouding 1.

The high strength warp-weft same-nature fabric that the utility model adopted has following characteristics:

(1) warp-weft same-nature fabric requires to be divided into polyamide fabric and aramid fiber cloth etc. according to the product functional performance.

(2) warp-weft same-nature can guarantee the stressed uniformity of cloth.

(3) for materials such as polyamide fabric and aramid fiber cloth, performance can reach the intensity of steel plate, is keeping under the equal intensity its rigidity and weight and cost well below steel plate but advantage is a cloth.

The utility model is in process, the warp-weft same-nature fabric surfacing does not need to handle required acid treatment of steel plate and boiling water flushing, direct figure brush coating stick, compare with steel plate and to reduce treatment process greatly, reduced cost of production, also reduce product weight, can reduce cost of transportation greatly, increased product market competitiveness.Adopt lamination high strength warp-weft same-nature fabric to improve the performance and the outward appearance of product, guaranteed the product functional performance, improved the application life of product.

Claims (1)

1. shock insulation rubber bearing comprises rubber body and the upper and lower shrouding that is entrenched in the body upper and lower end face, it is characterized in that, is arranged at intervals with several layers high strength warp-weft same-nature layer of cloth between the described upper and lower shrouding.
