Description

【０００１】
【発明の属する技術分野】
本発明は、単独であるいは他の鉛直方向の支承，減衰，復元機能を備えた支承装置と共に構造物に取り付けられて、構造物に生じる水平力を減衰させる水平バネ特性を有する水平力減衰免震装置に関する。
【０００２】
【従来の技術】
構造物に生じる地震等による振動を減衰させる装置としては、従来から鉛直方向の支承，減衰，復元機能を合せた多機能の減衰装置が知られている。しかし、このような多機能の免震装置は、装置の規模が大きくなると共に高価になり、その反面、鉛直方向の支承，減衰，復元等の機能全てをバランス良く備えることは困難であり、何らかの面で不十分さを備えていた。これに対して、鉛直方向の支承，減衰，復元の内のいずれかの機能に絞って、単一で優れた機能を発揮させる機能分離支承構造が注目されている。すなわち、それぞれ単一の優れた機能を備えた装置を組み合せて、トータルで鉛直方向の支承，減衰，復元等の機能全てをバランス良く発揮させると共に、装置全体のコストパフォーマンスを高めようというものである。
【０００３】
このような機能分離型の支承装置としては、例えば特許文献１に示すように、橋桁の下端と橋脚の上端間に鉛直支承部材が介在して鉛直方向の荷重を受けて、上下方向及び左右方向の振動を減衰させると共に、互いに対向する橋桁と橋脚の側面にゴム弾性体材料等による緩衝材が取り付けられて、各緩衝材により水平方向の振動を減衰させている。しかし、この緩衝材によれば、橋桁と橋脚間のスペースによっては適正な大きさの緩衝材を設置できなくなり、そのため十分な水平方向の支承ができなくなるという問題がある。
【０００４】
また、特許文献２に示すように、固定支持部材に、上部が開放されると共に横断面円形の容器を固定し、その容器内に同心的に配置した金属製つる巻きばねの下端部を、容器の底板に固定し、金属製つる巻きばねの上端部を可動支承部材の下部に固定し、つる巻きばね内に同心的に配置された抵抗部材の上部を、振動体を支持する可動支承部材の下部に固定し、容器内に減衰液を収容した、免震支承体が知られている。しかし、この免震支承体の場合、抵抗部材は配置されているが、主としてつる巻きばねにより水平方向の振動を減衰させるものであり、減衰力が十分ではなく、また容器上端と可動支承部材との間に隙間があるため、容器内に収容された減衰液が外部に飛散するおそれがある。

【発明が解決しようとする課題】
本発明は上記した問題を解決しようとするもので、橋梁等の構造物に生じる水平方向の振動を有効に減衰させることが可能な水平力減衰免震装置を提供することを目的とする。
【０００７】
【課題を解決するための手段】
上記目的を達成するために、上記請求項１に記載の発明の構成上の特徴は、単独であるいは他の鉛直方向の支承，減衰，復元機能を備えた支承装置と共に構造物に取り付けられて、構造物に生じる水平力を減衰させる水平バネ特性を有する水平力減衰免震装置であって、構造物に取り付けられる上下一対の平板状の取付部材と、厚肉の筒状であって、その軸方向両端間にかけて内部に金属製のコイルバネが同軸状に埋設されており、軸方向両端にて一対の取付部材に密着して取り付けられたゴム弾性体部材と、ゴム弾性体部材の密閉された空洞部内に配設されて一対の取付部材に密着して取り付けられた塑性部材とを設けたことにある。ここで、塑性部材としては、鉛、プラスチック等が使用される。
【０００８】
上記のように構成した請求項１の発明においては、大地震等により、減衰免震装置が水平方向の大きな衝撃を受けたとき、ゴム弾性体部材が一対の取付部材に密着して取り付けられており、かつ内部に金属製のコイルバネが両端間に同軸状に埋設されているため、両者が一体となって構造物に生じる水平方向の振動を有効に減衰させることができる。また、ゴム弾性体部材の空洞部内に塑性部材が配設されて一対の取付部材に密着して取り付けられていることにより、水平方向の振動を減衰させる効果がさらに高められる。
【０００９】
また、上記請求項２に記載の発明の構成上の特徴は、単独であるいは他の鉛直方向の支承，減衰，復元機能を備えた支承装置と共に構造物に取り付けられて、構造物に生じる水平力を減衰させる水平バネ特性を有する水平力減衰免震装置であって、構造物に取り付けられる上下一対の平板状の取付部材と、厚肉の筒状であって、その軸方向両端間にかけて内部に金属製のコイルバネが同軸状に埋設されており、軸方向両端にて一対の取付部材に密着して取り付けられたゴム弾性体部材と、ゴム弾性体部材の密閉された空洞部内に充填された高粘性液体とを設けたことにある。ここで、高粘性液体としては、オイル、シリコーン等の液体樹脂材料等が使用される。
【００１０】
上記のように構成した請求項２の発明においては、上記請求項１と同様に、大地震等により、装置が水平方向の大きな衝撃を受けたとき、ゴム弾性体部材とコイルバネが一体となって水平方向の振動を有効に減衰させることができる。また、ゴム弾性体部材の空洞部内に高粘性液体が充填されて介在することにより、水平方向の振動を減衰させる効果がさらに高められる。
【００１１】
また、上記請求項３に記載の発明の構成上の特徴は、前記請求項２に記載の水平力減衰免震装置において、一対の取付部材のいずれかに取り付けられて空洞部内に延びた抵抗部材を設けたことにある。ここで、抵抗部材としては、鉛、プラスチック、エラストマー等が使用される。このように、一対の取付部材のいずれかに取り付けられて空洞部内に延びた抵抗部材を設けたことにより、請求項２の発明の効果がさらに高められる。
【００１２】
【発明の実施の形態】
以下、本発明の実施形態について図面を用いて説明する。図１は、同実施形態である水平力減衰免震装置を一部破断正面図により示したものである。この水平力減衰免震装置１０は、構造物に取り付けられる上下一対の取付部材１１，１２と、取付部材１１，１２に密着して取り付けられて、内部に金属製のコイルバネ１３が両端間に同軸状に埋設された筒状のゴム弾性体部材１４と、ゴム弾性体部材１４の密閉された空洞部１５内に配設されて一対の取付部材１１，１２に密着して取り付けられた塑性部材１６とを有している。
【００１３】
取付部材１１，１２は、長方形の金属板であり、大きさが例えば（５００〜１０００）ｍｍ×（５００〜１０００）ｍｍ×２２ｍｍｔであり、四隅に板面を貫通した取付孔（図示しない）を設けている。ゴム弾性体部材１４は、円筒状の内外周面が、わずかに傾斜した螺旋状の溝１４ａによって仕切られており、各溝１４ａ間がそれぞれ径方向内外方に円弧状に膨出して、全体として螺旋状に膨出した凹凸形状になっている。ゴム弾性体部材１４は、例えば最大外径φ４００ｍｍ、最小内径φ３００ｍｍで、径方向の最大厚さが５０ｍｍとなっている。そして、ゴム弾性体部材１４自体の内部の中心位置には、コイルバネ１３がその螺旋形状に合わせて埋設されている。ゴム弾性体部材１４の軸方向両端が、加硫接着あるいは接着剤により取付部材１１，１２に接着固定されている。
【００１４】
コイルバネ１３は、例えば線径がφ１０ｍｍである。コイルバネ１３の両端は、取付部材１１，１２に対して、溶接あるいはねじ込み等により固定されている。塑性部材１６は、円柱形の鉛であって、外径がゴム弾性体部材１４の内径よりわずかに小さくなっており、その両端面が、取付部材１１，１２に対して、接着等により固定されている。水平力減衰免震装置１０は、取付部材１１，１２を構造物である橋桁及び橋脚に、ねじ等で固定することにより取り付けられる。
【００１５】
上記構成の実施形態においては、大地震等により、水平力減衰免震装置１０が水平方向の大きな衝撃を受けたとき、ゴム弾性体部材１４が一対の取付部材１１，１２に密着して取り付けられており、かつ内部の両端間に金属製のコイルバネ１３が同軸状に埋設されているため、両者が一体となって水平方向の振動を有効に減衰させることができる。また、ゴム弾性体部材１４の空洞部１５に塑性部材１６が挿入されて一対の取付部材１１，１２に密着して配置されており、ゴム弾性体部材１４と当接することにより、さらに水平方向の減衰力が高められる。このように、水平力減衰免震装置１０を単独で用いることにより、あるいは他の鉛直方向の支承，減衰，復元機能を備えた支承装置と共に橋梁等の構造物に取り付けられて、地震等により構造物に生じる水平方向の振動を有効に減衰させることができる。
【００１６】
つぎに、上記実施形態の変形例１について説明する。
変形例１では、図２に示すように、上記実施形態において塑性部材１６を設ける代りに、ゴム弾性体部材１４の空洞部１５内に高粘性液体であるシリコーン１８を充填したものであり、その他の構成については上記実施形態と同様である。その結果、変形例１においても、上記実施形態と同様の効果が得られると共に、塑性部材に代る高粘性のシリコーン１８が介在することにより、水平方向の振動を減衰させる効果がさらに高められる。
【００１７】
つぎに、上記実施形態の変形例２について説明する。
変形例２では、図３に示すように、上記変形例１において、さらに上側の取付部材１１の下面に抵抗部材１９が取り付けられて空洞部１５に充填されたシリコーン１８内に延びるようにされており、その他の構成については上記実施形態と同様である。その結果、変形例２においても、変形例１と同様の効果が得られると共に、抵抗部材１９がゴム弾性体部材１４に当接することにより、水平方向の減衰力がさらに高められる。なお抵抗部材１９については、上側の取付部材１１の代りに下側の取付部材１２に取り付けてもよい。
【００１８】
なお、上記実施形態及び変形例において、水平力減衰免震装置１０がもつ全復元力を１００とした場合、装置におけるコイルバネ１３の寄与率は３０％以上であり、好ましくは５０％以上とすることで、装置の復元機能をより満足させることができる。なお、上記実施形態及び変形例においては、水平力減衰免震装置１０を橋梁における水平方向の振動を減衰するために用いているが、橋梁以外の構造物の水平方向の振動を減衰に用いることもできる。その他、上記実施形態に示した水平力減衰免震装置については一例であり、本発明の主旨を逸脱しない範囲において、種々変更して実施することができる。
【００１９】
【発明の効果】
上記請求項１の発明によれば、大地震等により減衰免震装置が水平方向の大きな衝撃を受けたとき、コイルバネが同軸状に埋設されたゴム弾性体部材が一対の取付部材に密着して取り付けられているため、両者が一体となって水平方向の振動を有効に減衰させることができる。また、ゴム弾性体部材の空洞部内に塑性部材が挿入されて一対の取付部材に密着して配置されていることにより、さらに水平方向の減衰力が高められる。なお、塑性部材の代りに、高粘性の液体を封入することによっても同様の効果が得られ、さらに取付部材に取り付けられて空洞部内に延びた抵抗部材を設けることにより、さらに水平振動を減衰させる効果が高められる（請求項２，３の発明の効果）。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a horizontal force damping seismic isolation device having a horizontal spring characteristic to attenuate a horizontal force generated in a structure, alone or together with another vertical bearing, damping and restoring bearing device. Equipment related.
[0002]
[Prior art]
2. Description of the Related Art As a device for attenuating vibration caused by an earthquake or the like occurring in a structure, a multifunctional damper having a vertical bearing, damping and restoring functions is known. However, such a multifunctional seismic isolation device becomes expensive as the size of the device increases, and on the other hand, it is difficult to provide all functions such as vertical support, damping, and restoration in a well-balanced manner. In terms of inadequacy. On the other hand, attention has been paid to a function-separated bearing structure that exhibits a single excellent function by focusing on any one of vertical bearing, damping, and restoration. That is, by combining devices each having a single excellent function, all functions such as vertical support, damping, restoration, etc. are exhibited in a well-balanced manner, and the cost performance of the entire device is improved. .

As such a function-separated type bearing device, for example, as shown in Patent Document 1, a vertical bearing member is interposed between a lower end of a bridge girder and an upper end of a pier to receive a load in a vertical direction, and to be vertically and horizontally moved. In addition, a damping material such as a rubber elastic material is attached to the side surfaces of the bridge girder and the pier facing each other, and the vibration in the horizontal direction is damped by each damping material. However, according to this cushioning material, there is a problem that it is not possible to install a cushioning material of an appropriate size depending on the space between the bridge girder and the pier, so that sufficient horizontal support cannot be performed.
[0004]
Further, as shown in Patent Document 2, a container having an open top and a circular cross section is fixed to a fixed support member, and the lower end of a metal helical spring concentrically arranged in the container is fixed to the container. The upper end of the metal helical spring is fixed to the lower part of the movable support member, and the upper part of the resistance member concentrically arranged in the helical spring is connected to the movable support member supporting the vibrating body. BACKGROUND ART A seismic isolation bearing body fixed to a lower portion and containing a damping liquid in a container is known. However, in the case of this seismic isolation bearing, although the resistance member is arranged, the vibration in the horizontal direction is mainly attenuated by the helical spring, and the damping force is not sufficient. Since there is a gap between them, the damping liquid contained in the container may be scattered to the outside.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a partially cutaway front view showing a horizontal force damping seismic isolation device according to the embodiment. This horizontal force damping seismic isolation device 10 is mounted on a pair of upper and lower mounting members 11 and 12 attached to a structure, and mounted in close contact with the mounting members 11 and 12, and a metal coil spring 13 is coaxially disposed between both ends. Cylindrical rubber elastic member 14 buried in a shape, and a plastic member 16 disposed in a closed cavity 15 of the rubber elastic member 14 and closely mounted to the pair of mounting members 11 and 12. And
[0013]
The mounting members 11 and 12 are rectangular metal plates having a size of, for example, (500 to 1000) mm × (500 to 1000) mm × 22 mmt, and have mounting holes (not shown) penetrating the plate surface at four corners. Provided. The rubber elastic member 14 has a cylindrical inner and outer peripheral surface partitioned by a slightly inclined spiral groove 14a, and each groove 14a bulges radially inward and outward in an arc shape, as a whole. It has an uneven shape that bulges spirally. The rubber elastic member 14 has, for example, a maximum outer diameter of 400 mm and a minimum inner diameter of 300 mm, and a maximum radial thickness of 50 mm. The coil spring 13 is embedded at the center position inside the rubber elastic member 14 itself in conformity with the spiral shape. Both ends in the axial direction of the rubber elastic member 14 are bonded and fixed to the mounting members 11 and 12 by vulcanization bonding or an adhesive.
[0014]
The coil spring 13 has a wire diameter of, for example, φ10 mm. Both ends of the coil spring 13 are fixed to the mounting members 11 and 12 by welding or screwing. The plastic member 16 is a columnar lead whose outer diameter is slightly smaller than the inner diameter of the rubber elastic member 14, and whose both end surfaces are fixed to the mounting members 11 and 12 by bonding or the like. ing. The horizontal force damping seismic isolation device 10 is mounted by fixing the mounting members 11 and 12 to a bridge girder and a pier, which are structures, with screws or the like.

In the embodiment having the above configuration, when the horizontal force damping seismic isolation device 10 receives a large horizontal shock due to a large earthquake or the like, the rubber elastic member 14 is attached to the pair of attachment members 11 and 12 in close contact. Since the metal coil spring 13 is coaxially buried between both ends of the inside, the two can be integrated to effectively attenuate horizontal vibration. Further, a plastic member 16 is inserted into the hollow portion 15 of the rubber elastic member 14 and is disposed in close contact with the pair of mounting members 11 and 12. The damping force is increased. As described above, the horizontal force damping seismic isolation device 10 can be used alone or attached to a structure such as a bridge together with other vertical bearing, damping, and restoring functions, and can be used in a structure such as an earthquake.

The other configuration is the same as the above embodiment. As a result, also in Modification Example 2, the same effect as in Modification Example 1 is obtained, and the damping force in the horizontal direction is further increased by the resistance member 19 abutting against the rubber elastic member 14. The resistance member 19 may be attached to the lower attachment member 12 instead of the upper attachment member 11.

In the above-described embodiments and modifications, when the total restoring force of the horizontal force damping seismic isolation device 10 is set to 100, the contribution rate of the coil spring 13 in the device is 30% or more, and preferably 50% or more. Thus, the restoration function of the apparatus can be more satisfied. In the above-described embodiment and modifications, the horizontal force damping seismic isolation device 10 is used to attenuate the horizontal vibration of the bridge, but the horizontal vibration of a structure other than the bridge is used for the attenuation. You can also. In addition, the horizontal force damping seismic isolation device described in the above embodiment is an example, and various modifications can be made without departing from the gist of the present invention.
[0019]
【The invention's effect】
According to the first aspect of the present invention, when the damping seismic isolation device receives a large horizontal shock due to a large earthquake or the like, the rubber elastic member in which the coil spring is coaxially embedded closely contacts the pair of mounting members. Since they are attached, the two can be integrated to effectively attenuate horizontal vibrations. Further, since the plastic member is inserted into the cavity of the rubber elastic member and is arranged in close contact with the pair of mounting members, the damping force in the horizontal direction is further increased. A similar effect can be obtained by enclosing a high-viscosity liquid in place of the plastic member. Further, by providing a resistance member attached to the attachment member and extending into the cavity, horizontal vibration is further attenuated. The effect is enhanced (the effects of the inventions of claims 2 and 3).
