従来の弾性支承装置は、弾性体それ自体のせん断弾性率は方向性がなく、直交する一方の方向と直交する他方の方向に対して同一の性能値（許容変位量・剛性）を有するものである。 In the conventional elastic bearing device, the elastic modulus of the elastic body itself is not directional, and has the same performance value (allowable displacement amount / rigidity) in one direction orthogonal to the other direction orthogonal to the orthogonal direction. be.

しかしながら、構造物の種別等により、直交する一方の方向の必要性能値（許容変位量・剛性）と直交する他方の方向の必要性能値（許容変位量・剛性）が異なる場合がある。
この場合、弾性支承の形状（構造）を決定するにあたり、その形状（構造）を必要性能の低い方に対応させて設定すると変位性能が不足することになるため、必要性能の高い方に対応させて形状（構造）を設定することになるが、これでは弾性体の平面寸法が大きくなり、弾性支承が大型になり、コスト高を招くことにもなるという問題があった。 However, the required performance value (allowable displacement amount / rigidity) in one orthogonal direction and the required performance value (allowable displacement amount / rigidity) in the other orthogonal direction may differ depending on the type of structure or the like.
In this case, when determining the shape (structure) of the elastic bearing, if the shape (structure) is set according to the one with the lower required performance, the displacement performance will be insufficient, so the one with the higher required performance should be used. However, this has the problem that the plane dimension of the elastic body becomes large, the elastic bearing becomes large, and the cost increases.

本発明は、前記従来技術の持つ問題点を解決する、構造が簡単で、弾性体の寸法を大きくすることなく、直交する一方の方向の必要性能値（許容変位量・剛性）と直交する他方の方向の必要性能値（許容変位量・剛性）を異なるように設定することが可能な構造物用支承装置を提供することを目的とする。 The present invention solves the problems of the prior art, has a simple structure, and is orthogonal to the required performance value (allowable displacement amount / rigidity) in one orthogonal direction without increasing the size of the elastic body.

本発明の実施形態を図により説明する。図１～図４は、本発明の構造物用支承装置の一実施形態を示す図である。 An embodiment of the present invention will be described with reference to the drawings. 1 to 4 are views showing an embodiment of the structural bearing device of the present invention.

構造物用支承装置１は、建築物や橋梁等の構造物の上部構造２と下部構造３との間に配置される。上部構造２にはソールプレート４がセットボルト５で固定され、下部構造３にはベースプレート６がアンカーボルト７で固定される。 The structural bearing device 1 is arranged between the superstructure 2 and the substructure 3 of a structure such as a building or a bridge. The sole plate 4 is fixed to the upper structure 2 with set bolts 5, and the base plate 6 is fixed to the lower structure 3 with anchor bolts 7.

構造物用支承装置１は、上部構造２と下部構造間に配置される弾性体を有する複数の弾性支承を備えている。複数の弾性支承の内、一方向変位伝達阻止手段を介して直交する一方の方向（以下、「Ｘ方向」という。）のみの応力が伝達される第一弾性支承８と、Ｘ方向と直交する他方の方向（以下、「Ｙ方向」という。）の全方向の応力が伝達される第二弾性支承９を有している。 The structural bearing device 1 includes a plurality of elastic bearings having an elastic body arranged between the superstructure 2 and the lower structure. Of the plurality of elastic bearings, the first elastic bearing 8 in which stress is transmitted in only one direction (hereinafter referred to as "X direction") orthogonal to each other via the one-way displacement transmission blocking means is orthogonal to the X direction. It has a second elastic bearing 9 to which stress in all directions in the other direction (hereinafter referred to as "Y direction") is transmitted.

第一弾性支承８と第二弾性支承９を上部構造２と下部構造３との間に配置する際、第一弾性支承８と第二弾性支承９の高さを同じにするか、高さが異なる場合には高さが高い弾性支承の一部をソールプレート４又はベースプレート６に形成した凹部に収容して配置し、複数の弾性支承を上部構造と２と下部構造３の同一空間に配置し、支承高さを低く押えることが可能になる。 When arranging the first elastic bearing 8 and the second elastic bearing 9 between the upper structure 2 and the lower structure 3, the height of the first elastic bearing 8 and the second elastic bearing 9 should be the same or the height should be the same. If they are different, a part of the elastic bearings having a high height is housed in the recess formed in the sole plate 4 or the base plate 6 and arranged, and a plurality of elastic bearings are arranged in the same space of the upper structure and the lower structure 2 and the lower structure 3. , It becomes possible to keep the bearing height low.

第一弾性支承８は、ゴム等の弾性体８ａの上下に上連結鋼板８ｂと下連結鋼板８ｃが加硫成形により一体化されている。図に示される実施形態では、第一弾性支承８の下連結鋼板８ｃが固定ボルト８ｄでベースプレート６に固定され、上連結鋼板８ｂは上部構造側のソールプレート４に固定していないが、上連結鋼板８ｂをソールプレート４に固定し、下連結鋼板８ｃをベースプレート６に固定しないようにしても良い。 In the first elastic bearing 8, an upper connecting steel plate 8b and a lower connecting steel plate 8c are integrated by vulcanization molding above and below an elastic body 8a such as rubber. In the embodiment shown in the figure, the lower connecting steel plate 8c of the first elastic bearing 8 is fixed to the base plate 6 by the fixing bolt 8d, and the upper connecting steel plate 8b is not fixed to the sole plate 4 on the upper structure side, but is upper connected. The steel plate 8b may be fixed to the sole plate 4 and the lower connecting steel plate 8c may not be fixed to the base plate 6.

第一弾性支承８の上連結鋼板８ｂに上部部材１０が固定ボルト１０ｂで固定される。上部部材１０は、上連結鋼板８ｂより大きく形成される。上連結鋼板８ｂの両側に一対のサイドブロック１１が固定ボルト１２によりソールプレート４に固定される。一対のサイドブロック１１は、上連結鋼板８ｂと上部部材１０との段差と係合してＹ方向変位阻止手段を形成する。 The upper member 10 is fixed to the upper connecting steel plate 8b of the first elastic bearing 8 with a fixing bolt 10b. The upper member 10 is formed larger than the upper connecting steel plate 8b. A pair of side blocks 11 are fixed to the sole plate 4 by fixing bolts 12 on both sides of the upper connecting steel plate 8b. The pair of side blocks 11 engage with the step between the upper connecting steel plate 8b and the upper member 10 to form a displacement preventing means in the Y direction.

また、上部部材１０に係合ピン１０ａを形成し、係合ピン１０ａをソールプレート４に形成されたＸ方向に伸びる長溝４ａと係合してＹ方向変位阻止手段を形成しても良い。サイドブロック１１によるＹ方向変位阻止手段と係合ピン１０ａと長溝４ａとの係合によるＹ方向変位阻止手段を併用しても良い。第一弾性支承８は、Ｘ方向の応力が付加されると弾性体８ａを変形させることなくＸ方向に変位する。 Further, the engaging pin 10a may be formed on the upper member 10 and the engaging pin 10a may be engaged with the elongated groove 4a extending in the X direction formed on the sole plate 4 to form the Y-direction displacement preventing means. The Y-direction displacement preventing means by the side block 11 and the Y-direction displacement preventing means by engaging the engaging pin 10a and the long groove 4a may be used in combination. When stress in the X direction is applied, the first elastic bearing 8 is displaced in the X direction without deforming the elastic body 8a.

図１（ｂ）に示すように、上部部材９の上面に低摩擦材１３を配置し、ソールプレート４の下面とスライド面を形成しても良い。図１（ｂ）に示す実施形態では、第一弾性支承８は、鉛直力支持機能を有する。 As shown in FIG. 1 (b), the low friction material 13 may be arranged on the upper surface of the upper member 9 to form the lower surface of the sole plate 4 and the slide surface. In the embodiment shown in FIG. 1 (b), the first elastic bearing 8 has a vertical force supporting function.

第二弾性支承９は、ゴム等の弾性体９ａの上下に上連結鋼板９ｂと下連結鋼板９ｃが加硫成形により一体化されている。第二弾性支承９の下連結鋼板９ｃが固定ボルト９ｄでベースプレート６に固定され、上連結鋼板９ｂは固定ボルト９ｄでソールプレート４に固定される。図１（ａ）に示す実施形態では、第二弾性支承９は、ベースプレート６とソールプレート４と空間を形成することなく固定されるので第二弾性支承９は鉛直力支持機能を有する。第二弾性支承９は、全方向の応力に対して弾性体９ａを変形させ全方向に変位する。 In the second elastic bearing 9, the upper connecting steel plate 9b and the lower connecting steel plate 9c are integrated by vulcanization molding above and below the elastic body 9a such as rubber. The lower connecting steel plate 9c of the second elastic bearing 9 is fixed to the base plate 6 by the fixing bolt 9d, and the upper connecting steel plate 9b is fixed to the sole plate 4 by the fixing bolt 9d. In the embodiment shown in FIG. 1 (a), the second elastic bearing 9 is fixed to the base plate 6 and the sole plate 4 without forming a space, so that the second elastic bearing 9 has a vertical force supporting function. The second elastic bearing 9 deforms the elastic body 9a with respect to stress in all directions and displaces in all directions.

図１（ｃ）に示すように、第一弾性支承８の上部部材９の上面とソールプレート４の下面が接しないようにしても良い。図１（ｃ）に示す実施形態では第一弾性支承８は鉛直力支持機能を有せず水平力支持機能を有する。 As shown in FIG. 1 (c), the upper surface of the upper member 9 of the first elastic bearing 8 and the lower surface of the sole plate 4 may not be in contact with each other. In the embodiment shown in FIG. 1 (c), the first elastic bearing 8 does not have a vertical force supporting function but has a horizontal force supporting function.

図１（ｄ）に示すように、第二弾性支承９の下連結鋼板９ｃをベースプレート６に固定し、上連結鋼板９ｂをソールプレート４に形成した凹部４ｂに上連結鋼板９ｂの全周が凹部に接するように嵌合し、上連結鋼板９ｂとソールプレート４の凹部４ｂの下面との間に空隙が形成するようにする。このように構成することによる第二弾性支承９には全方向の変位が伝達されるが、鉛直力支持機能を有しない。 As shown in FIG. 1 (d), the lower connecting steel plate 9c of the second elastic bearing 9 is fixed to the base plate 6, and the upper connecting steel plate 9b is formed in the sole plate 4 and the entire circumference of the upper connecting steel plate 9b is recessed in the recess 4b. It is fitted so as to be in contact with the upper connecting steel plate 9b so that a gap is formed between the upper connecting steel plate 9b and the lower surface of the recess 4b of the sole plate 4. With this configuration, the second elastic bearing 9 is transmitted with displacement in all directions, but does not have a vertical force support function.

図１（ａ）、図１（ｂ）に示すように、第一弾性支承８と第二弾性支承９が鉛直力支持機能を有する場合はシューとして使用する。 As shown in FIGS. 1 (a) and 1 (b), when the first elastic bearing 8 and the second elastic bearing 9 have a vertical force supporting function, they are used as shoes.

図１（ｃ）、図１（ｄ）に示すように、第一弾性支承８と第二弾性支承９が鉛直力支持機能を有しない場合は、水平力支持機能を有するバッファとして使用する。バッファとして使用する場合は、別に鉛直力支持機構が必要である。 As shown in FIGS. 1 (c) and 1 (d), when the first elastic bearing 8 and the second elastic bearing 9 do not have the vertical force support function, they are used as a buffer having a horizontal force support function. When used as a buffer, a separate vertical force support mechanism is required.

図１～図４に示される実施形態では、第一弾性支承８の配置数が第二弾性支承９の配置数より多いが、設定された直交する一方の方向の必要性能値（許容変位量・剛性）と直交する他方の方向の必要性能値（許容変位量・剛性）との設定値に応じて、第二弾性支承９の配置数を第一弾性支承８の配置数より多くしたり、弾性体８ａ，９ａの体積量や静的せん断弾性係数を変えて必要性能値にしても良い。 In the embodiment shown in FIGS. 1 to 4, the number of arrangements of the first elastic support 8 is larger than the number of arrangements of the second elastic support 9, but the required performance value (allowable displacement amount / allowable displacement amount) in one of the set orthogonal directions is set. Depending on the set value of the required performance value (allowable displacement amount / rigidity) in the other direction orthogonal to the rigidity), the number of arrangements of the second elastic support 9 may be larger than the number of arrangements of the first elastic support 8 or the elasticity may be increased. The required performance values may be obtained by changing the volume of the bodies 8a and 9a and the static shear elastic modulus.

図１～図４に示される実施形態では、複数の第一弾性支承８と第二弾性支承９が共通のベースプレート６に固定されているが、構造物の種類に応じて要求される配置が変化する場合、個々の第一弾性支承８、第二弾性支承９を別々に上部構造２と下部構造３間に配置しても良い。 In the embodiments shown in FIGS. 1 to 4, a plurality of first elastic bearings 8 and second elastic bearings 9 are fixed to a common base plate 6, but the required arrangement varies depending on the type of structure. In this case, the individual first elastic bearings 8 and second elastic bearings 9 may be separately arranged between the superstructure 2 and the lower structure 3.
