Claims

[Scope of utility model registration request]

(1) An upper shoe with a convex portion on the lower surface that is fixed to the upper structure such as a bridge girder, and a box-shaped lower shoe with an opening formed on the upper surface that is buried and fixed almost the entire height to the lower structure such as a bridge pier. A vibration isolating rubber support comprising an intermediate plate having a fitting recess on the upper surface and an engaging recess on the lower surface, a vibration isolating rubber body having a predetermined spring constant, and an elastic bearing pressure piece, A vibration isolating rubber body, an intermediate plate, and an elastic bearing pressure piece are provided in the lower shoe, the vibration isolating rubber body is placed on the bottom surface, and the intermediate plate is fitted into the engagement recess of the intermediate plate on the upper surface thereof. In addition, the elastic bearing pressure piece is tightly interposed and housed between the side surface of the intermediate plate and/or the vibration isolating rubber body and the inner surface of the lower shoe, and the upper shoe is inserted into the fitting recess of the intermediate plate. A vibration isolating rubber bearing, characterized in that the convex portions thereof are fitted into each other, and the elastic bearing pressure piece prevents buckling of the vibration isolating rubber body. .

(2) The anti-vibration rubber bearing according to claim 1, wherein the anti-vibration rubber body is constructed by integrally polymerizing and laminating a rubber body and a reinforcing plate.

(3) The anti-vibration rubber bearing according to claim 1 or 2, wherein the elastic bearing pressure piece is formed by integrally overlapping a rubber body and a reinforcing plate.

(4) Elastic bearing pressure pieces are tightly interposed between the inner surface of the lower shoe and the side surface of the intermediate plate and/or the vibration isolating rubber body on the bridge axis and either in the direction perpendicular to the bridge axis or in one direction in the bridge axis direction. The anti-vibration rubber bearing according to claim 1, 2 or 3 of the utility model registration claim, characterized in that:
