【発明の属する技術分野】本発明は橋梁用ゴム支承に係

よう構成した橋梁用ゴム支承に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rubber bearing for a bridge, and more particularly to a rubber bearing for a bridge in which a compressive strain remains in the entire rubber layer even when the girder rotates.

Flanges are integrally provided above and below the laminated rubber.

とによりこのゴムの膨出量をわずかなものとし、ゴムの
耐荷力を増大させている。水平変位に大しては、ゴムが
せん断変形することにより変位を吸収している。When a vertical load is applied to the rubber bearing, the rubber layer is compressed and deformed so as to be pushed to the side. However, the thickness of the rubber layer is reduced by interposing a hard plate layer to reduce the thickness of the rubber layer. The amount of swelling is made small to increase the load carrying capacity of the rubber. For the horizontal displacement, the rubber absorbs the displacement by shear deformation.

【０００４】回転に対しては、ゴムの弾性によりこれを

し、端部で浮き上りが生じないようにする必要がある。
即ち、桁の回転変位が生じてもゴム層にはその全体に圧
縮ひずみが残るようにゴム支承を設計する。[0004] The rotation is absorbed by the elasticity of the rubber. At this time, the rubber bearing needs to support the load over the entire area and prevent lifting at the ends.
That is, the rubber bearing is designed so that even if a rotational displacement of the spar occurs, the compressive strain remains in the entire rubber layer.

が、このようにゴム層を厚くすると次のような短所が生
じる。As described above, the thickness of the rubber layer is increased in order to construct the rubber bearing so that the compressive strain always remains even when the girder rotates. The following disadvantages occur when the rubber layer is made thicker.

【０００６】 ゴム層の形状係数の下限を割ってしま
い、支承の寸法を大きくせざるを得なくなる。The lower limit of the shape factor of the rubber layer is divided, and the size of the bearing must be increased.

【０００７】 支承の水平ばねが小さくなり、地震時

【０００８】 この水平移動量が支承ゴムの許容ひず

くせざるを得ない。In order to prevent the horizontal movement amount from exceeding the allowable strain of the bearing rubber, the planar dimension of the bearing must be increased.

【０００９】これらの短所は、いずれも桁の回転による
ゴムのひずみを、それを上回る圧縮ひずみでカバーしよ
うとするために起きるものである。[0009] All of these disadvantages arise because the rubber strain caused by the rotation of the girder is intended to be covered with a compressive strain exceeding that.
