従来の橋梁桁支承用パツドは、硬質ゴム等の弾性材から
のみ或る単純な板状体であるか又は硬質ゴムと硬質合或
樹脂を一体的に或形したものが多く用いられている。Conventional bridge girder supporting pads are often a simple plate-like body made only of an elastic material such as hard rubber, or are formed integrally with hard rubber and hard composite or resin.
しかしこれ等のものは、橋梁桁が重いため強度面で不充
分な場合が多いと共に橋軸直角方向への移動が抑制でき
ず、これを補うため金属製のストッパーを同時に使用さ
れる゛場合が多い等の難点を有していた。However, these types of bridge girders are often insufficient in terms of strength because they are heavy, and they cannot suppress movement in the direction perpendicular to the bridge axis.To compensate for this, metal stoppers are sometimes used at the same time. There were many disadvantages such as:
この考案は、上記従来例の難点を解消したもので、以下
その構或を実施例として示した図面に従って説明する。This invention solves the drawbacks of the above-mentioned conventional example, and its structure will be explained below with reference to the drawings showing examples.

。The embodiment shown in FIG. 1 has a plate metal member 3a inside the rubber body 2.
are buried at appropriate intervals vertically, and a round bar-shaped metal member 3b is buried between plate-shaped metal members 3a. Although deformation is possible in the direction of the bridge axis as shown in FIG. 4, the deformation is suppressed in the direction perpendicular to the bridge axis.
第２図に示す実施例は、第１図の丸棒状金属部材３ｂを
代えて細い板状金属部材３Ｃを用いたものであり、第１
図のパツド１と同様の変形状態を得ることになる。The embodiment shown in FIG. 2 uses a thin plate-shaped metal member 3C in place of the round bar-shaped metal member 3b in FIG.
A deformed state similar to that of pad 1 in the figure will be obtained.
第３図に示す実施例は、外縁を内方へ屈曲させた屈曲部

形が可能であるが、橋軸直角方向には変形が抑制される
ことになる。In the embodiment shown in FIG. 3, two plate-shaped metal members 3d forming a bent portion 4 whose outer edges are bent inward are buried in a rubber body 2 in a manner that they face each other. In the case of this pad 1, due to the action of the bent portion 4, deformation is possible in the direction of the bridge axis shown by the arrow, but deformation is suppressed in the direction perpendicular to the bridge axis.
従って、このパツド１はゴム体２の弾力性と、金属部材
３の形状及び埋設状態を種々変更することにより、橋軸
方向への変形可能及び橋軸直角方向への変形抑制の程度
を必要に応じたものとして設定することができる。Therefore, by variously changing the elasticity of the rubber body 2 and the shape and buried state of the metal member 3, this pad 1 can be deformed in the direction of the bridge axis and the degree of deformation in the direction perpendicular to the bridge axis can be suppressed. It can be set as appropriate.
第５図は、このパツド１の使用状態を示すもので、橋台

移動現象が生じた際にはパツド１の変形抑制作用で、移
動を抑制することになる。FIG. 5 shows the usage state of this pad 1, which is interposed between an abutment 5 and a bridge girder 6, and is used when the bridge girder 6 moves in the direction of the bridge axis indicated by the arrow. This is absorbed by the deformation action of the pad 1, and when movement in the direction perpendicular to the bridge axis occurs, the movement is suppressed by the deformation suppressing action of the pad 1.
この考案は上述の通り、金属部材３をゴム体２内に埋設
