Purpose of the Invention (1) Field of Industrial Use This invention relates to a support for supporting a bridge, particularly an inter-building connecting bridge, and more specifically, for the displacement of the superstructure in all horizontal directions. The present invention relates to a bearing with an anti-floating mechanism that is suitable for use in an inter-building connecting bridge that allows this and restrains the vertical lift of the superstructure.
【０００２】 (2) 従来の技術 従来より一般に、橋梁に使用される支承においては、橋桁などの上部構造の傾 きあるいは該傾き及び橋軸方向の伸縮をともに許容する機能と、該上部構造に作 用する上揚力を受け止める機能が備えられている。そして、上部構造に作用する 上揚力に対しては、一般に橋脚などの下部構造に固定される下沓の橋軸直角方向 両端に突設された凸部に該上部構造に固定される上沓の上面に張り出して固定さ れたサイドブロックによって受け止める構造が採用されている。(2) Conventional Technology Conventionally, in a bearing used for a bridge, generally, a function of allowing inclination of an upper structure such as a bridge girder or the inclination and expansion / contraction in the bridge axial direction, and It is equipped with a function to receive the lifting force used.

【００２４】 （実施例の作用・効果） 上述した構成からなる本実施例の浮上り防止機構付き支承Ｓは、上部構造Ｇの 傾き、水平変位、更にまた上揚力に対して以下のように作用する。(Operation / Effect of Embodiment) The bearing S with the anti-lifting mechanism of the present embodiment, which has the above-described configuration, acts as follows with respect to the inclination, horizontal displacement, and upper lift of the superstructure G. To do.
【００２５】 上部構造Ｇに車両・通行者等の通行により傾きを生じた場合、該傾きは上部取 付け板１と一体に傾動する上部係合ブロック４が、そのあご部４Ａにより支承本 体３の支柱体２０を一体的に変位させ、支柱体２０は球面ベアリング２１に対し て傾動自在となっており、上部構造Ｇは球面ベアリング２１回りに回転変位する 。 このとき、下部係合ブロック５のあご部５Ａは支承本体３の下部あご部３Ｂに 対して所定の隙間を存するので、支柱体２０の傾動に対して障害とならない。When the upper structure G is tilted by a vehicle, a pedestrian, or the like, the tilt causes the upper engaging block 4 that tilts integrally with the upper mounting plate 1 to be supported by the jaw portion 4 A of the main body 3. The column body 20 is integrally displaced so that the column body 20 can be tilted with respect to the spherical bearing 21, and the upper structure G is rotationally displaced around the spherical bearing 21. At this time, the jaw portion 5A of the lower engaging block 5 has a predetermined gap with respect to the lower jaw portion 3B of the support body 3, so that it does not hinder the tilting of the column 20.
【００２６】 上部構造Ｇに水平変位力が作用した場合、当該変位の橋軸方向成分は上部取付 け板１の下面と支承本体３の滑り板２２との摺接作用により、また、当該水平変 位の橋軸直角方向成分は、下部取付け板２の上面と支承本体３の球面ベアリング ２１の下面との摺接作用により許容される。 また、水平方向の変位に対しては、支承本体の上部あご部と上部係合ブロック のあご部とが、また、支承本体の下部あご部と下部係合ブロックのあご部とが、 それぞれあご部に沿う方向に移動が許容されているので、上部構造の水平方向の 変位を何ら支障をきたすことなく許容する。 該上部構造Ｇの橋軸方向の移動は、上部サポート板６が支承本体３に当接する ことにより制限される。また、橋軸直角方向の移動は、支承本体３が下部サポー ト板７に当接することにより制限される。 なお、通常の温度変化による橋軸方向の変位は、上記した水平変位の橋軸方向 成分に含められる。When a horizontal displacement force is applied to the upper structure G, the bridge axial component of the displacement is caused by the sliding contact between the lower surface of the upper mounting plate 1 and the sliding plate 22 of the bearing body 3 and also the horizontal displacement force. The component in the direction perpendicular to the bridge axis is allowed by the sliding contact between the upper surface of the lower mounting plate 2 and the lower surface of the spherical bearing 21 of the support body 3. Also, for horizontal displacement, the upper jaw of the bearing body and the jaw of the upper engaging block, and the lower jaw of the bearing body and the jaw of the lower engaging block, Since it is allowed to move in the direction along, the horizontal displacement of the superstructure is allowed without any hindrance. The movement of the upper structure G in the bridge axis direction is restricted by the upper support plate 6 coming into contact with the support body 3. Further, the movement in the direction perpendicular to the bridge axis is restricted by the support body 3 coming into contact with the lower support plate 7. The displacement in the bridge axis direction due to normal temperature change is included in the bridge axis direction component of the horizontal displacement described above.
【００２７】 上部構造Ｇに過大な上揚力が生じた場合、支承本体３は上部係合ブロック４の あご部４Ａを介して持ち上げられるが、引き続いて支承本体３の下部あご部３Ｂ が下部係合ブロック５のあご部５Ａに衝接し、それ以上の浮上りが阻止される。When an excessive lift force is generated in the upper structure G, the support body 3 is lifted via the jaw portion 4A of the upper engagement block 4, but the lower jaw portion 3B of the support body 3 is subsequently engaged in the lower engagement. It collides with the jaw portion 5A of the block 5 and is prevented from further lifting.
【００２８】 本実施例の浮上り防止機構付き支承Ｓによれば、支承本体３の上部あご部３Ａ と上部係合ブロック４のあご部４Ａとで橋軸方向の変位を許容し、支承本体３の 下部あご部３Ｂと下部係合ブロック５のあご部５Ａとで橋軸直角方向の変位を許 容し、この結果、水平方向のどの方向に対しても対応でき、かつ、これと同時に 、傾動変位を許容するとともに浮上り防止機能を発揮するので、多様な振動特性 をなすビル間連絡橋に好適である。According to the bearing S with the lifting prevention mechanism of this embodiment, the upper jaw portion 3A of the bearing body 3 and the jaw portion 4A of the upper engagement block 4 allow displacement in the bridge axial direction, and the bearing body 3 The lower jaw 3B and the jaw 5A of the lower engaging block 5 allow displacement in the direction perpendicular to the bridge axis, and as a result, can respond to any horizontal direction, and at the same time, tilting is possible. It is suitable for connecting bridges between buildings, which has various vibration characteristics, as it allows displacement and exerts a function of preventing rising.
