Description

本発明は、ゴム支承装置に関し、さらに詳しくは、ゴム積層体のゴム層の仕様を変更することなく、或いはゴム層の仕様変更を最小限にして、上部工の回転変位に対する吸収性能を向上させたゴム支承装置に関するものである。   The present invention relates to a rubber bearing device, and more particularly, to improve the absorption performance against rotational displacement of a superstructure without changing the specification of the rubber layer of the rubber laminate or minimizing the change of the specification of the rubber layer. The present invention relates to a rubber bearing device.

橋桁等を支持するゴム支承装置には様々なタイプがあり、あらゆる方向の変位を吸収するゴム支承装置が提案されている（特許文献１参照）。図６に例示するように、橋脚などの下部工１３の上に設置され、橋桁などの上部工１２を支えるゴム支承装置１には、上部工１２の回転変位を吸収する性能が要求される。上部工１２の回転変位に対する吸収性能を向上するためには、例えば、鋼板とゴム層とを交互に積層して形成したゴム積層体２のゴム厚を増大させたり、ゴム層の弾性率を小さくするなどの対策がある。しかしながら、このような従来の対策では、ゴム積層体のゴム層の仕様を変更する必要があり、これに伴って、コストの増加が大きくなるという問題があった。特に、ゴム厚の増大は装置全体の厚さ増大につながってコストが大幅に増加する。そのため、ゴム積層体のゴム層の仕様を変更することなく、或いは、ゴム層の仕様変更を最小限にして、上部工の回転変位に対する吸収性能を向上させたゴム支承装置が求められていた。   There are various types of rubber bearing devices that support bridge girders and the like, and rubber bearing devices that absorb displacement in all directions have been proposed (see Patent Document 1). As illustrated in FIG. 6, the rubber bearing device 1 that is installed on the substructure 13 such as a bridge pier and supports the superstructure 12 such as a bridge girder is required to have a capability of absorbing the rotational displacement of the superstructure 12. In order to improve the absorption performance against the rotational displacement of the superstructure 12, for example, the rubber thickness of the rubber laminate 2 formed by alternately laminating steel plates and rubber layers is increased, or the elastic modulus of the rubber layer is decreased. There are measures such as However, with such conventional measures, there is a problem that it is necessary to change the specifications of the rubber layer of the rubber laminate, and the cost increases accordingly. In particular, an increase in the rubber thickness leads to an increase in the thickness of the entire apparatus, which greatly increases the cost. Therefore, there has been a demand for a rubber bearing device that improves the absorption performance against the rotational displacement of the superstructure without changing the specification of the rubber layer of the rubber laminate or minimizing the specification change of the rubber layer.

特開平６−２７２２１６号公報JP-A-6-272216

本発明の目的は、ゴム積層体のゴム層の仕様を変更することなく、或いはゴム層の仕様変更を最小限にして、上部工の回転変位に対する吸収性能を向上させたゴム支承装置を提供することにある。   An object of the present invention is to provide a rubber bearing device that improves the absorption performance against the rotational displacement of the superstructure without changing the specification of the rubber layer of the rubber laminate or minimizing the specification change of the rubber layer. There is.

上記目的を達成するため本発明のゴム支承装置は、鋼板とゴム層とを交互に積層したゴム積層体と、ゴム積層体の橋軸直角方向両側に配置したサイドブロックとを有するゴム支承装置において、前記鋼板のうちゴム積層体の上端表面に配置した上端鋼板の橋軸直角方向両端部と、この両端部に対向する前記サイドブロックとを連結する連結ゴム部材を設け、前記サイドブロックをゴム積層体の橋軸直角方向両側に固定して据付けた際に、前記連結ゴム部材が、前記ゴム積層体に圧縮力を付与する方向にせん断変形した状態になる構成にしたことを特徴とするものである。   To achieve the above object, a rubber bearing device of the present invention is a rubber bearing device having a rubber laminate in which steel plates and rubber layers are alternately laminated, and side blocks arranged on both sides of the rubber laminate in a direction perpendicular to the bridge axis. A connecting rubber member is provided for connecting the both ends of the upper end steel plate arranged in the upper end surface of the rubber laminate in the direction perpendicular to the bridge axis and the side blocks facing the both ends of the steel plate, and the side blocks are laminated with rubber. When fixed and installed on both sides in the direction perpendicular to the bridge axis of the body, the connecting rubber member is configured to be in a state of shear deformation in a direction in which a compressive force is applied to the rubber laminate. is there.

ここで、前記連結ゴム部材と前記上端鋼板およびサイドブロックとが加硫接着により一体化されている仕様にすることもできる。前記サイドブロックが分離可能な上端突出部を有する構造であり、この上端突出部が前記連結ゴム部材に連結されている仕様にすることもできる。前記連結ゴム部材に補強材を設けることもできる。   Here, it can also be set as the specification with which the said connection rubber member, the said upper end steel plate, and the side block are integrated by vulcanization adhesion. The side block may have a structure having a separable upper end protrusion, and the upper end protrusion may be connected to the connecting rubber member. A reinforcing material may be provided on the connecting rubber member.

本発明のゴム支承装置によれば、ゴム積層体の上端表面に配置した上端鋼板の橋軸直角方向両端部と、この両端部に対向するサイドブロックとを連結する連結ゴム部材を設け、サイドブロックをゴム積層体の橋軸直角方向両側に固定して据付けた際に、連結ゴム部材が、ゴム積層体に圧縮力を付与する方向にせん断変形した状態になる構成にしたので、上部工が回転変位する際に、予めせん断変形した連結ゴム部材が、この回転変位を吸収するように機能する。このように、ゴム積層体のゴム層が担う上部工の回転変位に対する吸収性能を、連結ゴム部材が補助するので、ゴム積層体のゴム層の仕様を変更させることなく、或いはゴム層の仕様変更を最小限にして、上部工の回転変位に対する吸収性能を向上させることができる。   According to the rubber bearing device of the present invention, the connecting rubber member is provided for connecting the both ends of the upper end steel plate disposed on the upper end surface of the rubber laminate in the direction perpendicular to the bridge axis and the side blocks facing the both ends. Is fixed on both sides of the rubber laminate in the direction perpendicular to the bridge axis, and the connecting rubber member is in a state of shear deformation in the direction to apply compressive force to the rubber laminate. At the time of displacement, the connecting rubber member that has been shear-deformed in advance functions to absorb this rotational displacement. In this way, the connecting rubber member assists in the absorption performance against the rotational displacement of the superstructure that the rubber layer of the rubber laminate bears, so the specification of the rubber layer can be changed without changing the specification of the rubber layer of the rubber laminate. The absorption performance with respect to the rotational displacement of the superstructure can be improved.

以下、本発明のゴム支承装置を図に示した実施形態に基づいて説明する。   Hereinafter, a rubber bearing device of the present invention will be described based on an embodiment shown in the drawings.

図１、図２に例示するように本発明ゴム支承装置１は、鋼板３とゴム層５とを交互に積層したゴム積層体２と、ゴム積層体２の橋軸直角方向両側に配置したサイドブロック７とを有している。この実施形態は、ゴム積層体２、鋼板３は平面視で矩形状になっている。尚、図面では、橋軸方向をＸ方向、橋軸直角方向をＹ方向として示している。   As illustrated in FIGS. 1 and 2, the rubber bearing device 1 of the present invention includes a rubber laminate 2 in which steel plates 3 and rubber layers 5 are alternately laminated, and sides disposed on both sides of the rubber laminate 2 in a direction perpendicular to the bridge axis. Block 7. In this embodiment, the rubber laminate 2 and the steel plate 3 are rectangular in plan view. In the drawing, the bridge axis direction is shown as the X direction, and the direction perpendicular to the bridge axis is shown as the Y direction.

ゴム積層体２の鋼板３のうち、ゴム積層体２の上端表面に配置された上端鋼板３ａおよび下端表面に配置された下端鋼板３ｂは、他の鋼板３よりも厚くなっている。上端鋼板３ａの橋軸直角方向両側の上端角部には、橋軸方向に延びる切欠き部４が設けられている。この切欠き部４は、上端鋼板３ａの橋軸方向に所定長さで形成されており、上端鋼板３ａの橋軸方向の全長に渡って形成されていない。   Among the steel plates 3 of the rubber laminate 2, the upper end steel plate 3 a disposed on the upper end surface of the rubber laminate 2 and the lower end steel plate 3 b disposed on the lower end surface are thicker than the other steel plates 3. Cutouts 4 extending in the bridge axis direction are provided at the upper corners on both sides of the upper end steel plate 3a in the direction perpendicular to the bridge axis. The notch 4 is formed with a predetermined length in the bridge axis direction of the upper end steel plate 3a, and is not formed over the entire length of the upper end steel plate 3a in the bridge axis direction.

それぞれのサイドブロック７は、基部７ａと上端突出部７ｂとにより構成されている。上端突出部７ｂは、上端鋼板３ａの上方まで突出している。基部７ａにはボルト穴９が形成され、上端突出部７ｂには貫通穴８が形成されている。ボルト１０を貫通穴８に貫通させてボルト穴９に螺合させることにより、基部７ａと上端突出部７ｂとが一体に連結されてサイドブロック７が形成されている。このボルト１０を取り去ることにより、サイドブロック７は、基部７ａと上端突出部７ｂとに分解される。   Each side block 7 includes a base portion 7a and an upper end protruding portion 7b. The upper end protrusion 7b protrudes to above the upper end steel plate 3a. Bolt holes 9 are formed in the base portion 7a, and through holes 8 are formed in the upper end protruding portion 7b. By making the bolt 10 pass through the through hole 8 and screwed into the bolt hole 9, the base portion 7a and the upper end protruding portion 7b are integrally connected to form the side block 7. By removing this bolt 10, the side block 7 is disassembled into a base portion 7a and an upper end protruding portion 7b.

上端鋼板３ａの切欠き部４と、切欠き部４に対向する上端突出部７ｂとは、連結ゴム部材１１を介して連結されている。このように本発明では、上端鋼板３ａの橋軸直角方向両端部と、この両端部に対向するサイドブロック７とを連結する連結ゴム部材１１が設けられている。   The notch portion 4 of the upper end steel plate 3 a and the upper end protruding portion 7 b facing the notch portion 4 are connected via a connecting rubber member 11. Thus, in this invention, the connection rubber member 11 which connects the bridge block orthogonal direction both ends of the upper end steel plate 3a and the side block 7 which opposes this both ends is provided.

図３に例示するように、鋼板３、上端鋼板３ａ、下端鋼板３ｂと隣接するゴム層５とが加硫接着されてゴム積層体２が形成されるとともに、連結ゴム部材１１と上端鋼板３ａおよび上端突出部７ｂとが加硫接着されることにより一体物になっている。連結ゴム部材１１と、上端鋼板３ａおよびサイドブロック７とは、例えば、機械的な機構によって一体化することもできるが、より確実かつ容易に一体化するには加硫接着が好ましい。   As illustrated in FIG. 3, the steel plate 3, the upper end steel plate 3a, the lower end steel plate 3b and the adjacent rubber layer 5 are vulcanized and bonded to form the rubber laminate 2, and the connecting rubber member 11 and the upper end steel plate 3a and The upper end protruding portion 7b is integrated by vulcanization and bonding. The connecting rubber member 11, the upper end steel plate 3a, and the side block 7 can be integrated by, for example, a mechanical mechanism, but vulcanization bonding is preferable for more reliable and easy integration.

下端鋼板３ｂは、固定ボルトによりベースプレート６に固定され、ベースプレート６は、下部工１３に埋設されたアンカーに、固定ナットを螺合させることにより下部工１３に固定されている。上端鋼板３ａは、上部工１２の下面に取り付けられたソールプレートにボルト等により固定されている。   The lower end steel plate 3b is fixed to the base plate 6 by fixing bolts, and the base plate 6 is fixed to the lower work 13 by screwing a fixing nut to an anchor embedded in the lower work 13. The upper end steel plate 3a is fixed to a sole plate attached to the lower surface of the upper work 12 with bolts or the like.

このゴム支承装置１を設置する場合には、サイドブロック７の一部を構成する基部７ａが、ボルト等によってベースプレート６に固定されることにより、ベースプレート６に固定されたゴム積層体２の橋軸直角方向両側に基部７ａが設置される。   When the rubber bearing device 1 is installed, the base 7a constituting a part of the side block 7 is fixed to the base plate 6 with bolts or the like, so that the bridge shaft of the rubber laminate 2 fixed to the base plate 6 is obtained. Bases 7a are installed on both sides in the perpendicular direction.

次いで、図４に例示するように、ボルト１０を上端突出部７ｂの貫通穴８に貫通させてボルト穴９に螺合させることにより、連結ゴム部材１１をせん断変形させた状態にして、基部７ａと上端突出部７ｂとを一体に連結させる。このようにしてサイドブロック７をゴム積層体２の橋軸直角方向両側に固定して据付けが完了した際には、連結ゴム部材１１が、ゴム積層体２に圧縮力を付与する方向（上下方向）にせん断変形した状態になっている。即ち、連結ゴム部材１１のせん断変形によって、ゴム積層体２には予め圧縮力が作用している。   Next, as illustrated in FIG. 4, the bolt 10 is passed through the through hole 8 of the upper end protruding portion 7 b and screwed into the bolt hole 9, so that the connecting rubber member 11 is sheared and deformed, and the base portion 7 a. And the upper end protrusion 7b are integrally connected. When the side block 7 is fixed to the both sides of the rubber laminate 2 in the direction perpendicular to the bridge axis in this way and the installation is completed, the connecting rubber member 11 applies a compressive force to the rubber laminate 2 (vertical direction). ) In a state of shear deformation. That is, a compressive force is applied to the rubber laminate 2 in advance by the shear deformation of the connecting rubber member 11.

次いで、このゴム支承装置１の上に上部工１２が載置され、図６に例示したように橋桁などの上部工１２と橋脚などの下部工１３の間にゴム支承装置１が設置される。上部工１２に回転変位が生じた際には、主にゴム積層体２のゴム層５が、この回転変位を吸収するように機能するが、本発明では、予めせん断変形している連結ゴム部材１１も、この回転変位を吸収する。このように連結ゴム部材１１が、上部工１２の回転変位に対する吸収性能を補助するように機能する。   Next, the upper work 12 is placed on the rubber bearing apparatus 1, and the rubber bearing apparatus 1 is installed between the upper work 12 such as a bridge girder and the lower work 13 such as a bridge pier as illustrated in FIG. When rotational displacement occurs in the superstructure 12, the rubber layer 5 of the rubber laminate 2 mainly functions to absorb this rotational displacement. 11 also absorbs this rotational displacement. In this way, the connecting rubber member 11 functions to assist the absorption performance against the rotational displacement of the superstructure 12.

したがって、上部工１２の回転変位に対する吸収性能を向上させるために、ゴム積層体２のゴム層５を厚くすることや、ゴム層５の弾性率を小さくする必要がなくなる。或いは、上部工１２の回転変位に対する吸収性能を向上させるに際して、ゴム層５の厚さの増大を最小限にすることができ、または、ゴム層５の弾性率の低減を最小限にすることができる。このようにゴム積層体２のゴム層５の仕様を変更させることなく、或いはゴム層５の仕様変更を最小限にして、上部工１２の回転変位に対する吸収性能を向上させることができるので、コストの低減が可能になる。   Therefore, it is not necessary to increase the thickness of the rubber layer 2 of the rubber laminate 2 or reduce the elastic modulus of the rubber layer 5 in order to improve the absorption performance against the rotational displacement of the superstructure 12. Alternatively, in improving the absorption performance against the rotational displacement of the superstructure 12, an increase in the thickness of the rubber layer 5 can be minimized, or a reduction in the elastic modulus of the rubber layer 5 can be minimized. it can. As described above, the absorption performance against the rotational displacement of the superstructure 12 can be improved without changing the specification of the rubber layer 5 of the rubber laminate 2 or by minimizing the specification change of the rubber layer 5. Can be reduced.

この実施形態では、連結ゴム部材１１はゴムのみで形成されているが、図５に例示するように、連結ゴム部材１１に補強材１１ａを設けることもできる。補強材１１ａとしては、例えば、帆布等の繊維補強層を使用して、連結ゴム部材１１に単層または複数層埋設する。   In this embodiment, the connecting rubber member 11 is formed of only rubber. However, as illustrated in FIG. 5, the connecting rubber member 11 can be provided with a reinforcing material 11a. As the reinforcing material 11a, for example, a fiber reinforcing layer such as canvas is used, and a single layer or a plurality of layers are embedded in the connecting rubber member 11.

また、基部７ａと上端突出部７ｂとの間にスペーサを介在させたり、介在させるスペーサの厚さを変化させることにより、連結ゴム部材１１のせん断変形量を調整することもできる。したがって、連結ゴム部材１１に要求される回転変位に対する吸収性能に合致するように、連結ゴム部材１１のせん断変形量を調整することも可能になる。尚、サイドブロック７は、実施形態に例示した構造に限定されるものではない。   Further, the amount of shear deformation of the connecting rubber member 11 can be adjusted by interposing a spacer between the base portion 7a and the upper end protruding portion 7b or changing the thickness of the intervening spacer. Accordingly, it is possible to adjust the shear deformation amount of the connecting rubber member 11 so as to match the absorption performance with respect to the rotational displacement required for the connecting rubber member 11. The side block 7 is not limited to the structure exemplified in the embodiment.

この実施形態では、上部工１２に橋軸方向の力が作用して、上端鋼板３ａが橋軸方向に所定長さずれた際には、サイドブロック７の上端突出部７ｂの橋軸方向端面と切欠き部４の橋軸方向端面４ａとが当接する。これにより、連結ゴム部材１１が橋軸方向に過度にせん断変形することを防止することができるとともに、上部工１２の橋軸方向のずれ移動が規制される。上端鋼板３ａに設ける切欠き部４は、上端鋼板３ａの橋軸方向の全長に渡って形成することもできる。この切欠き部４を採用した場合は、上部工１２の橋軸方向のずれ移動は、連結ゴム部材１１のみによって規制される。   In this embodiment, when a bridge axis direction force acts on the superstructure 12 and the upper end steel plate 3a is displaced by a predetermined length in the bridge axis direction, the bridge axis direction end surface of the upper end protruding portion 7b of the side block 7 and The bridge axial direction end surface 4a of the notch 4 abuts. Thereby, it is possible to prevent the connecting rubber member 11 from being excessively sheared and deformed in the bridge axis direction, and the displacement movement of the superstructure 12 in the bridge axis direction is restricted. The notch 4 provided in the upper end steel plate 3a can be formed over the entire length of the upper end steel plate 3a in the bridge axis direction. When this notch 4 is employed, the displacement movement of the superstructure 12 in the bridge axis direction is restricted only by the connecting rubber member 11.
