Description

この発明は、例えば、下部建造物で上部建造物を支持する支承構造において、下部建造物及び上部建造物の間に介在させる建設分野における支承装置及びその取付方法に関する。 The present invention relates to, for example, a bearing device in a construction field that is interposed between a lower building and an upper building in a bearing structure that supports the upper building in the lower building, and a method of attaching the support device thereof.

従来より、例えば、免震建造物、橋梁、あるいは固定建造物同士を接続する接続部分等の振動や相対変位が生じる建造物において、可動支持する支承装置がある。例えば、特許文献１に示すような支承装置は、建物等の被支持建造物と、基礎等の支持建造物との間に配設され、被支持建造物に固定された上沓と、支持建造物に固定された下沓との境界面、つまり摺動面が摺動することで、境界面における面内方向に変位可能に支持することができる。 Conventionally, for example, there is a bearing device that movably supports a seismic isolated building, a bridge, or a building in which vibration or relative displacement occurs, such as a connecting portion connecting fixed structures. For example, a bearing device as shown in Patent Document 1 is arranged between a supported structure such as a building and a supported structure such as a foundation, and has a shoe fixed to the supported structure and a supported structure. By sliding the boundary surface with the lower shoe fixed to the object, that is, the sliding surface, it is possible to support the boundary surface so as to be displaceable in the in-plane direction.

このような支承装置２００は、例えば、図１０に示すように、下部建造物１００の上面に固定された下沓２１０と、上部建造物１１０の底面に固定された上沓２２０とで構成され、下沓２１０と上沓２２０の対向面が摺動自在に構成されている。
なお、図１０において、左半分は概略正面図を示し、右半分は概略断面図を示している。 As shown in FIG. 10, such a bearing device 200 is composed of, for example, a lower shoe 210 fixed to the upper surface of the lower building 100 and an upper shoe 220 fixed to the bottom surface of the upper building 110. The facing surfaces of the lower shoe 210 and the upper shoe 220 are slidably configured.
In FIG. 10, the left half shows a schematic front view, and the right half shows a schematic cross-sectional view.

下沓２１０は、下部建造物１００の上面に固定されるベースプレート２１１と、ベースプレート２１１に固定されたベースポット２１２と、ベースポット２１２の上面に配置され、摺動面を構成するピストン２１３とで構成され、ベースプレート２１１の周辺部や四隅に配置されたボルトなどの締結治具２１４によって下部建造物１００の上面に固定されている。 The lower shoe 210 is composed of a base plate 211 fixed to the upper surface of the lower structure 100, a base plate 212 fixed to the base plate 211, and a piston 213 arranged on the upper surface of the base plate 212 and forming a sliding surface. The base plate 211 is fixed to the upper surface of the lower building 100 by fastening jigs 214 such as bolts arranged at the peripheral portions and the four corners.

しかしながら、下沓２１０の上部には、上沓２２０が配置されているため、下部建造物１００の上面と上沓２２０との間に配置される下沓２１０を設置する場合や、ピストン２１３を交換するために下沓２１０を取り外す場合などにおいては、締結治具２１４が上部の上沓２２０と接触し、つまり上沓２２０が支障し、締結治具２１４をボルト孔に挿入できない、あるいは締結治具２１４をボルト孔から外すことができないなどの問題があった。そのため、上部建造物１１０をジャッキアップ等によって大きく持ち上げ、上部建造物１１０の底面と下部建造物１００の上面とのクリアランスを拡大させてから、締結治具２１４を締結する、あるいは取り外すなどの作業が必要であった。 However, since the upper shoe 220 is arranged on the upper part of the lower shoe 210, when installing the lower shoe 210 arranged between the upper surface of the lower structure 100 and the upper shoe 220, or replacing the piston 213. When removing the lower shoe 210 for this purpose, the fastening jig 214 comes into contact with the upper upper shoe 220, that is, the upper shoe 220 interferes and the fastening jig 214 cannot be inserted into the bolt hole, or the fastening jig There was a problem that the 214 could not be removed from the bolt hole. Therefore, after the upper building 110 is greatly lifted by jacking up or the like to increase the clearance between the bottom surface of the upper building 110 and the upper surface of the lower building 100, the fastening jig 214 is fastened or removed. It was necessary.

The extending direction is orthogonal to each other in a plan view.
Further, the downward protrusion amount of the fitting convex portion 33a is formed at the same height as the depth of the fitting groove 41 in the base plate 40 described later or at a height slightly shallower than the depth of the fitting groove 41.

図１、図２に示すように、挿着凹部３３ｂは、後述するピストン３１及びベースポット本体３３よりわずかに大きな径の円筒状空間であり、本実施形態においてはベースポット本体３３の高さに対して１／３程度の深さで形成されている。 As shown in FIGS. 1 and 2, the insertion recess 33b is a cylindrical space having a diameter slightly larger than that of the piston 31 and the base spot main body 33, which will be described later, and in the present embodiment, the height of the base spot main body 33. On the other hand, it is formed at a depth of about 1/3.

弾性プレート３２は、挿着凹部３３ｂよりわずかに小さな径の円形、且つ挿着凹部３３ｂの深さの半分程度の高さ（厚み）を有するゴム製の円盤状のプレートである。
下沓３の摺動面として機能するピストン３１は、円盤状のステンレス製であり、摺動面を構成する一つの面に例えばＰＴＦＥ（ポリテトラフルオロエチレン）等のフッ素樹脂製のベアリングが取り付けられた円盤状体であり、自己潤滑性を有しており、表面の摩擦係数が低く設定されている。 The elastic plate 32 is a rubber disk-shaped plate having a circular diameter slightly smaller than the insertion recess 33b and a height (thickness) of about half the depth of the insertion recess 33b.
The piston 31 that functions as the sliding surface of the lower sill 3 is made of disk-shaped stainless steel, and a fluororesin bearing such as PTFE (polytetrafluoroethylene) is attached to one surface constituting the sliding surface. It is a disc-shaped body, has self-lubricating properties, and has a low coefficient of friction on the surface.

上述のように構成されたベースポット本体３３、弾性プレート３２及びピストン３１は、ピストン３１と弾性プレート３２とを重ねて挿着凹部３３ｂに挿着することによって、ピストン３１がベースポット本体３３の上面から適宜の高さ分が突出する態様の円形ベースポット３０が構成される。
なお、ピストン３１は、弾性プレート３２によって弾性支持された状態となる。 In the base spot main body 33, the elastic plate 32 and the piston 31 configured as described above, the piston 31 and the elastic plate 32 are overlapped and inserted into the insertion recess 33b, so that the piston 31 is attached to the upper surface of the base spot main body 33. A circular base spot 30 having a shape in which an appropriate height protrudes from the base is configured.
The piston 31 is in a state of being elastically supported by the elastic plate 32.

図１乃至図３に示すように、ベースプレート４０は、平面視正方形状の適宜の厚みを有する鋼製の板状体であり、円形ベースポット３０の嵌合凸部３３ａと嵌合する嵌合溝４１が上面に形成されており、下部建造物１００の上面に対してボルト結合するためのボルト孔（図示省略）が周縁部に設けられている。 As shown in FIGS. 1 to 3, the base plate 40 is a steel plate-like body having an appropriate thickness in a square shape in a plan view, and is a fitting groove that fits with the fitting convex portion 33a of the circular base spot 30. 41 is formed on the upper surface, and a bolt hole (not shown) for bolting to the upper surface of the substructure 100 is provided on the peripheral surface.

嵌合溝４１は、ベースプレート４０の厚みに対して半分程度の深さと、平面視正方形を構成する一辺の１／３程度の幅を有し、奥行方向Ｌに貫通する断面矩形状の溝である。嵌合溝４１は、ベースポット本体３３の直径よりわずかに長い径であり、ベースポット本体３３が配置される円形溝部４２が平面視中央に形成されている。
また、図２に示すように、円形溝部４２の幅方向Ｗの側方上面には、幅方向Ｗの内向き三角形の三角表示４３が設けられている。 The fitting groove 41 is a groove having a depth of about half with respect to the thickness of the base plate 40 and a width of about one-third of one side forming a square in a plan view, and a groove having a rectangular cross section penetrating in the depth direction L. .. The fitting groove 41 has a diameter slightly longer than the diameter of the base spot main body 33, and the circular groove portion 42 in which the base spot main body 33 is arranged is formed in the center in a plan view.
Further, as shown in FIG. 2, an inward triangular triangular display 43 in the width direction W is provided on the lateral upper surface of the circular groove portion 42 in the width direction W.

それぞれが上述のように構成されるとともに、下沓３を構成するベースプレート４０と円形ベースポット３０とは、円形溝部４２に円形ベースポット３０が配置され、位置規制されることとなる。
また、ベースプレート４０と円形ベースポット３０とは、図１に示すように、上沓２におけるスライドプレート２２の底面（支承装置１における上側摺動面）と、下沓３におけるピストン３１の上面（支承装置１における下側摺動面）とが摺動することで、スライドプレート２２とピストン３１とが対向する対向面方向（本実施形態において水平方向）に摺動可能な可動支承である支承装置１を構成することができる。 The base plate 40 and the circular basespot 30 which form the lower shoe 3 are respectively configured as described above, and the circular basespot 30 is arranged in the circular groove portion 42, and the positions of the base plate 40 and the circular basespot 30 are restricted.
Further, as shown in FIG. 1, the base plate 40 and the circular base plate 30 are the bottom surface of the slide plate 22 in the upper shoe 2 (upper sliding surface in the bearing device 1) and the upper surface of the piston 31 in the lower shoe 3 (bearing). A bearing device 1 which is a movable bearing that can slide in the facing surface direction (horizontal direction in the present embodiment) in which the slide plate 22 and the piston 31 face each other by sliding the lower sliding surface in the device 1. Can be configured.

続いて、支承装置１の取付方法について図４及び図５とともに説明する。
まず、図４（ａ）に示すように、上沓２を上部建造物１１０の底面に取り付けるともに、下沓３のベースプレート４０を下部建造物１００の上面に固定する。 Subsequently, a method of attaching the bearing device 1 will be described with reference to FIGS. 4 and 5.
First, as shown in FIG. 4A, the upper shoe 2 is attached to the bottom surface of the upper building 110, and the base plate 40 of the lower shoe 3 is fixed to the upper surface of the lower building 100.

この状態で、ベースポット本体３３の挿着凹部３３ｂに弾性プレート３２及びピストン３１をこの順で装着して円形ベースポット３０を構成するとともに、ベースプレート４０の嵌合溝４１の延長方向の外側（本実施形態では奥行方向Ｌ）に円形ベースポット３０を配置する。このとき、嵌合凸部３３ａが奥行方向Ｌに向くように（三角表示３４が幅方向Ｗを向くように）円形ベースポット３０を配置する。 In this state, the elastic plate 32 and the piston 31 are mounted in this order in the insertion recess 33b of the base plate main body 33 to form the circular base spot 30, and the outside of the fitting groove 41 of the base plate 40 in the extension direction (this). In the embodiment, the circular base spot 30 is arranged in the depth direction L). At this time, the circular base spot 30 is arranged so that the fitting convex portion 33a faces the depth direction L (so that the triangular display 34 faces the width direction W).

そして、図４（ｂ）及び図５（ａ）に示すように、底面視小判型の嵌合凸部３３ａを奥行方向Ｌの嵌合溝４１に嵌合させ、円形溝部４２に向かって奥行方向Ｌにスライドさせる。このとき、ベースポット本体３３の幅方向Ｗの両側に設けた三角表示３４を幅方向Ｗの外側から確認することができる。 Then, as shown in FIGS. 4 (b) and 5 (a), the bottom view oval-shaped fitting convex portion 33a is fitted into the fitting groove 41 in the depth direction L, and is fitted in the depth direction toward the circular groove portion 42. Slide to L. At this time, the triangular displays 34 provided on both sides of the base spot main body 33 in the width direction W can be confirmed from the outside of the width direction W.

さらに、円形ベースポット３０をスライドさせて、図４（ｃ）及び図５（ｂ）に示すように、嵌合凸部３３ａの中心（ベースポット本体３３の中心）と円形溝部４２の中心とが略一致する所定位置まで円形ベースポット３０を嵌入させる。 Further, by sliding the circular base spot 30, as shown in FIGS. 4 (c) and 5 (b), the center of the fitting convex portion 33a (the center of the base spot main body 33) and the center of the circular groove portion 42 are aligned. The circular base spot 30 is fitted to a predetermined position that substantially matches.

なお、嵌合凸部３３ａの中心（ベースポット本体３３の中心）と円形溝部４２の中心とが略一致する所定位置では、ベースポット本体３３の幅方向Ｗの両側周面に設けた三角表示３４の下側の先端と、ベースプレート４０の上面に設けた三角表示４３の内側の先端とが略一致することとなる。 At a predetermined position where the center of the fitting convex portion 33a (the center of the base spot main body 33) and the center of the circular groove portion 42 substantially coincide with each other, the triangular display 34 provided on both peripheral surfaces of the base spot main body 33 in the width direction W. The lower tip and the inner tip of the triangular display 43 provided on the upper surface of the base plate 40 substantially coincide with each other.

そして、ベースポット本体３３の幅方向Ｗの両側周面に設けた三角表示３４の下側の先端と、ベースプレート４０の上面に設けた三角表示４３の内側の先端とが略一致する所定位置まで嵌入された円形ベースポット３０を、ベースプレート４０に対する円形ベースポット３０の位置を規制するように、平面方向において９０度回転させる。 Then, the lower tip of the triangular display 34 provided on both peripheral surfaces of the base plate body 33 in the width direction W and the inner tip of the triangular display 43 provided on the upper surface of the base plate 40 are fitted to a predetermined position where they substantially coincide with each other. The circular basespot 30 is rotated 90 degrees in the plane direction so as to regulate the position of the circular basespot 30 with respect to the base plate 40.

図４（ｄ）及び図５（ｃ）に示すように、円形溝部４２の内周面に外周面を沿わせて円形ベースポット３０を回転させることによって、底面視小判型の嵌合凸部３３ａは、平面視略円形状の円形溝部４２において幅方向Ｗに向くため、つまり嵌合凸部３３ａの幅方向Ｗの長さが嵌合溝４１より広くなるため、円形溝部４２によって嵌合凸部３３ａは奥行方向Ｌの移動が規制され、ベースプレート４０に対する円形ベースポット３０の位置を規制することができ、下沓３の組み付けが完了、すなわち支承装置１の取り付けは完了する。 As shown in FIGS. 4 (d) and 5 (c), by rotating the circular base spot 30 along the inner peripheral surface of the circular groove portion 42 along the outer peripheral surface, the bottom view oval-shaped fitting convex portion 33a Is oriented in the width direction W in the circular groove portion 42 having a substantially circular shape in a plan view, that is, the length of the fitting convex portion 33a in the width direction W is wider than that of the fitting groove 41. Therefore, the fitting convex portion is formed by the circular groove portion 42. In 33a, the movement in the depth direction L is restricted, the position of the circular base spot 30 with respect to the base plate 40 can be restricted, and the assembly of the lower sill 3 is completed, that is, the attachment of the support device 1 is completed.

逆に、支承装置１の解体は、上述した取付手順を逆に行って、まずベースプレート４０から円形ベースポット３０を取り外す。
詳しくは、ベースプレート４０に対して所定位置で規制された円形ベースポット３０を９０度回転させる。これにより、幅方向Ｗに向いていた嵌合凸部３３ａは、嵌合溝４１の延長方向である奥行方向Ｌに向くため、嵌合溝４１に嵌合凸部３３ａを沿わせて円形ベースポット３０を奥行方向Ｌにスライドさせて取り外す。円形ベースポット３０を取り外した後は、上部建造物１１０の底面から上沓２を取り外し、下沓３のベースプレート４０を下部建造物１００の上面から取り外して、支承装置１の解体は完了する。
なお、支承装置１全体を取り外さずとも、ピストン３１や弾性プレート３２を交換するために円形ベースポット３０のみをベースプレート４０から取り外してもよい。 On the contrary, in the disassembly of the bearing device 1, the mounting procedure described above is reversed, and the circular base spot 30 is first removed from the base plate 40.
Specifically, the circular base spot 30 regulated at a predetermined position is rotated 90 degrees with respect to the base plate 40. As a result, the fitting convex portion 33a facing the width direction W faces the depth direction L, which is an extension direction of the fitting groove 41, so that the fitting convex portion 33a is aligned with the fitting groove 41 and is a circular base spot. Slide 30 in the depth direction L to remove it. After removing the circular base spot 30, the upper shoe 2 is removed from the bottom surface of the upper structure 110, and the base plate 40 of the lower shoe 3 is removed from the upper surface of the lower structure 100 to complete the dismantling of the bearing device 1.
It should be noted that only the circular base spot 30 may be removed from the base plate 40 in order to replace the piston 31 and the elastic plate 32 without removing the entire bearing device 1.

このように、上部建造物１１０の底面に配置した上沓２、及び下部建造物１００の上面に配置した下沓３で構成されるとともに、上沓２及び下沓３の対向部分である摺動面が摺動する支承装置１において、下沓３が、下部建造物１００に固定されるベースプレート４０と、摺動面を構成するピストン３１と、ピストン３１を保持するベースポット本体３３とで構成され、下沓３で上沓２を支持する鉛直方向に対して交差する水平方向の外側から、ベースプレート４０に対してベースポット本体３３の嵌合凸部３３ａが嵌入される嵌合溝４１と、所定位置まで嵌入されたベースポット本体３３（円形ベースポット３０）のベースプレート４０に対する位置を規制する円形溝部４２とを備えるため、上部建造物１１０の底面と下部建造物１００の上面とのクリアランスを大きく変えることなく、円形ベースポット３０の交換や支承装置１の着脱をすることができる。 In this way, it is composed of an upper shoe 2 arranged on the bottom surface of the upper building 110 and a lower shoe 3 arranged on the upper surface of the lower building 100, and is a sliding portion facing the upper shoe 2 and the lower shoe 3. In the bearing device 1 on which the surface slides, the lower shoe 3 is composed of a base plate 40 fixed to the lower structure 100, a piston 31 forming the sliding surface, and a base spot main body 33 holding the piston 31. A fitting groove 41 into which the fitting convex portion 33a of the base spot main body 33 is fitted into the base plate 40 from the outside in the horizontal direction intersecting the vertical direction supporting the upper shoe 2 with the lower shoe 3 and predetermined. Since the shoe spot main body 33 (circular shoe spot 30) fitted to the position is provided with the circular groove portion 42 that regulates the position with respect to the base plate 40, the clearance between the bottom surface of the upper structure 110 and the upper surface of the lower structure 100 is significantly changed. The circular base spot 30 can be replaced and the bearing device 1 can be attached and detached without any problem.

詳述すると、摺動面を構成するピストン３１を保持するベースポット本体３３（円形ベースポット３０）を、下沓３で上沓２を支持する支持方向に対して交差する交差方向から、建造物に固定するベースプレート４０に対して嵌入し、所定位置まで嵌入された円形ベースポット３０のベースプレート４０に対する位置を規制できるため、上部建造物１１０の底面と下部建造物１００の上面とのクリアランスを大きく変えることなく、下沓３を取り付けたり、取り外したりして、支承装置１を着脱することができる。 More specifically, the building is formed from an intersection direction in which the basespot main body 33 (circular basespot 30) holding the piston 31 constituting the sliding surface intersects the support direction in which the upper shoe 2 is supported by the lower shoe 3. Since the position of the circular base spot 30 fitted to the base plate 40 fixed to the base plate 40 can be regulated and the position of the circular base spot 30 fitted to the base plate 40 can be regulated, the clearance between the bottom surface of the upper building 110 and the upper surface of the lower building 100 is significantly changed. The support device 1 can be attached and detached by attaching and detaching the lower shoe 3 without the need for it.

なお、上述の支持方向は、上下方向あるいは鉛直方向にわずかに交差する方向を含むものとし、上述の支持方向に対して交差する交差方向は、前記支持方向に対して交差していれば水平方向や、傾斜する方向を含むものとする。 It should be noted that the above-mentioned support direction includes a direction that slightly intersects the vertical direction or the vertical direction, and the intersection direction that intersects the above-mentioned support direction is the horizontal direction if it intersects the above-mentioned support direction. , The direction of inclination shall be included.

また、交差方向の外部から所定位置まで延びる嵌合溝４１がベースプレート４０に設けられ、嵌合溝４１に対してスライド可能に嵌合する嵌合凸部３３ａがベースポット本体３３に設けられており、円形溝部４２によって、摺動面に平行な平行方向への嵌合凸部３３ａの回転移動により、別部材を用いることなく、ベースプレート４０に対する円形ベースポット３０の位置を規制することができる。 Further, a fitting groove 41 extending from the outside in the crossing direction to a predetermined position is provided in the base plate 40, and a fitting convex portion 33a that is slidably fitted to the fitting groove 41 is provided in the base spot main body 33. By the circular groove portion 42, the position of the circular base spot 30 with respect to the base plate 40 can be regulated by the rotational movement of the fitting convex portion 33a in the parallel direction parallel to the sliding surface without using a separate member.

また、所定位置である円形溝部４２まで嵌入した円形ベースポット３０の回転移動によって円形ベースポット３０の位置を規制するため、奥行方向Ｌ方向に交差する方向に平行移動させて所定位置まで嵌入した円形ベースポット３０の位置を規制する場合に比べて、支承装置１自体をコンパクトに構成することができる。 Further, in order to regulate the position of the circular base spot 30 by the rotational movement of the circular base spot 30 fitted to the circular groove portion 42 which is the predetermined position, the circular base spot 30 is moved in parallel in the direction intersecting the depth direction L and fitted to the predetermined position. Compared with the case where the position of the base pot 30 is regulated, the support device 1 itself can be configured more compactly.

また、嵌合凸部３３ａが回転可能な空間である円形溝部４２を嵌合溝４１に設けるという簡単な構成で、ベースプレート４０における所定位置まで円形ベースポット３０を案内できるとともに、所定位置まで案内された円形ベースポット３０の位置や移動を規制することができる。 Further, with a simple configuration in which the circular groove portion 42, which is a space in which the fitting convex portion 33a is rotatable, is provided in the fitting groove 41, the circular base spot 30 can be guided to a predetermined position on the base plate 40 and is guided to a predetermined position. The position and movement of the circular base spot 30 can be regulated.

また、円形ベースポット３０を嵌入する所定位置を明示する三角表示３４，４３をベースポット本体３３の幅方向Ｗの下部と、円形溝部４２の側方の上面に備えているため、ベースプレート４０に対する所定位置に円形ベースポット３０を確実に移動させて、当該所定位置で位置規制することができる。 Further, since the triangular displays 34 and 43 that clearly indicate the predetermined positions for inserting the circular basespot 30 are provided on the lower portion of the basespot main body 33 in the width direction W and the upper surface on the side of the circular groove portion 42, the predetermined positions with respect to the base plate 40 are provided. The circular base spot 30 can be reliably moved to the position and the position can be regulated at the predetermined position.

また、図４（ｄ）に示すように、嵌合凸部３３ａの向きは外部から確認しがたいが、嵌合凸部３３ａの長手方向に対して交差する方向に設けた三角表示３４の位置を確認することで、円形ベースポット３０における嵌合凸部３３ａの向きを確認することができる。つまり、外部から円形ベースポット３０がベースプレート４０に対して位置規制された状態か、位置規制されていない状態かを容易に目視で確認することができる。 Further, as shown in FIG. 4D, although it is difficult to confirm the orientation of the fitting convex portion 33a from the outside, the position of the triangular display 34 provided in the direction intersecting the longitudinal direction of the fitting convex portion 33a. By confirming, the orientation of the fitting convex portion 33a in the circular base spot 30 can be confirmed. That is, it is possible to easily visually confirm from the outside whether the circular base spot 30 is positioned with respect to the base plate 40 or is not positioned.

なお、上述の説明では、嵌合凸部３３ａ及び嵌合溝４１を、略円柱状体であるベースポット本体３３の直径に対して半分程度の幅を有するとともに、円弧部分がベースポット本体３３の外周面と面一で構成され略小判型に形成し、円形溝部４２をベースポット本体３３の直径よりわずかに長い径で形成したが、嵌合凸部３３ａ及び円形溝部４２をベースポット本体３３の直径よりも短くあるいは長く形成してもよいし、嵌合凸部３３ａをベースポット本体３３の直径の半分程度の幅で形成せず、直径の半分程度の幅より広く形成しても狭く形成してもよい。 In the above description, the fitting convex portion 33a and the fitting groove 41 have a width of about half the diameter of the base spot main body 33, which is a substantially cylindrical body, and the arc portion is the base spot main body 33. It was formed flush with the outer peripheral surface and formed in a substantially oval shape, and the circular groove portion 42 was formed with a diameter slightly longer than the diameter of the base spot main body 33, but the fitting convex portion 33a and the circular groove portion 42 were formed on the base spot main body 33. It may be formed shorter or longer than the diameter, or the fitting convex portion 33a may not be formed with a width of about half the diameter of the base spot main body 33, but may be formed wider than about half the diameter or narrower. You may.

しかしながら、嵌合凸部３３ａ及び円形溝部４２をベースポット本体３３の直径よりも短く形成したり、嵌合凸部３３ａ及び嵌合溝４１の幅をベースポット本体３３の直径の半分より狭く形成した場合、上沓２を介して上部建造物１１０の荷重を支持する下沓３の一部である円形ベースポット３０において、ベースプレート４０との当接面積が小さくなり、嵌合凸部３３ａ及び円形溝部４２の底面に作用する圧力が増大するため、部材強度を向上させる必要が出てくる。そのため、嵌合凸部３３ａ及び円形溝部４２はベースポット本体３３の直径の１／３以上の長さで形成し、嵌合凸部３３ａ及び嵌合溝４１をベースポット本体３３の直径の１／３以上の幅で形成することが好ましい。 However, the fitting convex portion 33a and the circular groove portion 42 are formed shorter than the diameter of the base spot main body 33, and the width of the fitting convex portion 33a and the fitting groove 41 is formed to be narrower than half the diameter of the base spot main body 33. In the case, in the circular base spot 30 which is a part of the lower sill 3 which supports the load of the upper structure 110 through the upper sill 2, the contact area with the base plate 40 becomes smaller, and the fitting convex portion 33a and the circular groove portion Since the pressure acting on the bottom surface of the 42 increases, it becomes necessary to improve the member strength. Therefore, the fitting convex portion 33a and the circular groove portion 42 are formed to have a length of 1/3 or more of the diameter of the base spot main body 33, and the fitting convex portion 33a and the fitting groove 41 are formed at 1/3 of the diameter of the base spot main body 33. It is preferably formed with a width of 3 or more.

また、嵌合凸部３３ａ及び円形溝部４２をベースポット本体３３の直径よりも長く形成すると、円形ベースポット３０を回転させるための面積が大きくなり、支承装置１が大型化することになる。
また、嵌合凸部３３ａ及び円形溝部４２をベースポット本体３３の直径と同程度の長さで形成するとともに、嵌合凸部３３ａ及び嵌合溝４１の幅をベースポット本体３３の直径の半分より広く形成した場合、嵌合溝４１と嵌合凸部３３ａの側面との対向する面積が小さくなり、嵌合溝４１で奥行方向Ｌに案内されるベースポット本体３３の姿勢が安定しなくなるおそれがある。そのため、嵌合凸部３３ａ及び円形溝部４２はベースポット本体３３の直径の３／４以下の長さで形成し、嵌合凸部３３ａ及び嵌合溝４１をベースポット本体３３の直径の２／３以上の幅で形成することが好ましい。 Further, if the fitting convex portion 33a and the circular groove portion 42 are formed longer than the diameter of the base spot main body 33, the area for rotating the circular base spot 30 becomes large, and the bearing device 1 becomes large.
Further, the fitting convex portion 33a and the circular groove portion 42 are formed to have the same length as the diameter of the base spot main body 33, and the width of the fitting convex portion 33a and the fitting groove 41 is half the diameter of the base spot main body 33. If it is formed wider, the area where the fitting groove 41 and the side surface of the fitting convex portion 33a face each other becomes smaller, and the posture of the base spot main body 33 guided in the depth direction L by the fitting groove 41 may become unstable. There is. Therefore, the fitting convex portion 33a and the circular groove portion 42 are formed to have a length of 3/4 or less of the diameter of the base spot main body 33, and the fitting convex portion 33a and the fitting groove 41 are formed at 2 / of the diameter of the base spot main body 33. It is preferably formed with a width of 3 or more.

また、上述の説明では、ベースポット本体３３が円形である円形ベースポット３０について説明したが、図６及び図７に示すように、略円柱状でない略四角柱状体の角形ベースポット１３０による支承装置１ａであってもよい。 Further, in the above description, the circular basespot 30 in which the basespot main body 33 is circular has been described, but as shown in FIGS. 6 and 7, a bearing device using a square basespot 130 having a substantially square columnar shape that is not substantially cylindrical. It may be 1a.

支承装置１ａは、上述の支承装置１における円形ベースポット３０のベースポット本体３３が略円柱状であるのに対し、略四角柱状体であるベースポット本体１３３以外の構成については、支承装置１と同様であるため、同じ符号を付してその説明を省略する。 In the bearing device 1a, the base spot main body 33 of the circular base spot 30 in the above-mentioned bearing device 1 has a substantially cylindrical shape, whereas the support device 1a has a configuration other than the base spot main body 133 which is a substantially square columnar body. Since they are the same, the same reference numerals are given and the description thereof will be omitted.

支承装置１ａの角形のベースポット本体１３３は、略四角柱状体であり、その底面に嵌合凸部３３ａと同様の底面視小判型の嵌合凸部１３３ａが設けられている。
嵌合凸部１３３ａは、嵌合溝４１や円形溝部４２に対する大きさは嵌合凸部３３ａと同じであるが小判型の長手方向が底面視四角形のベースポット本体１３３の辺に対して平行な向きで配置されており、嵌合凸部１３３ａの中心と底面視四角形のベースポット本体１３３の中心とが略一致するように配置されている。 The square base spot main body 133 of the bearing device 1a is a substantially square columnar body, and a bottom view oval-shaped fitting convex portion 133a similar to the fitting convex portion 33a is provided on the bottom surface thereof.
The size of the fitting convex portion 133a with respect to the fitting groove 41 and the circular groove portion 42 is the same as that of the fitting convex portion 33a, but the longitudinal direction of the oval shape is parallel to the side of the base spot main body 133 having a quadrangular bottom view. They are arranged so as to be oriented so that the center of the fitting convex portion 133a and the center of the base spot main body 133 having a quadrangular bottom view coincide with each other.

そして、ベースポット本体１３３の幅方向Ｗの側面の下部に下向き三角形状の三角表示１３４が設けられている。
このように、略四角柱状の角形ベースポット１３０を有する支承装置１ａであっても、上述したような支承装置１と同様の効果を奏することができる。 A downward triangular triangular display 134 is provided at the lower part of the side surface of the base spot main body 133 in the width direction W.
As described above, even the bearing device 1a having the square base spot 130 having a substantially square columnar shape can obtain the same effect as the bearing device 1 as described above.

また、上述の説明では、嵌合溝４１が奥行方向Ｌにベースプレート４０を貫通した態様であった、つまり円形溝部４２における奥行方向Ｌの両側に嵌合溝４１が配置されており、ベースプレート４０の奥行方向Ｌの奥側から円形ベースポット３０や角形ベースポット１３０を嵌入したが、例えば、ベースプレート４０の手前側から円形ベースポット３０や角形ベースポット１３０を嵌入してもよい。
なお、上記各実施形態では、円形ベースポット３０や角形ベースポット１３０について説明してきたが、円形や角形に限定されるものではない。 Further, in the above description, the fitting groove 41 penetrates the base plate 40 in the depth direction L, that is, the fitting grooves 41 are arranged on both sides of the circular groove portion 42 in the depth direction L, and the base plate 40 The circular base spot 30 and the square base spot 130 are fitted from the back side in the depth direction L. For example, the circular base spot 30 and the square base spot 130 may be fitted from the front side of the base plate 40.
In each of the above embodiments, the circular basespot 30 and the square basespot 130 have been described, but the invention is not limited to the circular or square shape.

また、図８（ａ）乃至図８（ｃ）に示すように、嵌合溝４１が奥行方向Ｌにベースプレート４０を貫通せず、円形溝部４２の片側のみに嵌合溝４１が配置されていてもよい。
この場合、図８（ａ）に示すように、嵌合溝４１が配置された側の外側に円形ベースポット３０を配置し、図８（ｂ）に示すように、嵌合凸部３３ａを嵌合溝４１で円形溝部４２まで案内し、図８（ｃ）に示すように、円形溝部４２にて円形ベースポット３０を回転させて、円形溝部４２において円形ベースポット３０の位置を規制してもよい。 Further, as shown in FIGS. 8A to 8C, the fitting groove 41 does not penetrate the base plate 40 in the depth direction L, and the fitting groove 41 is arranged only on one side of the circular groove portion 42. May be good.
In this case, as shown in FIG. 8A, the circular base spot 30 is arranged outside the side where the fitting groove 41 is arranged, and as shown in FIG. 8B, the fitting convex portion 33a is fitted. Even if the circular groove portion 41 is guided to the circular groove portion 42 and the circular base spot 30 is rotated in the circular groove portion 42 to regulate the position of the circular base spot 30 in the circular groove portion 42, as shown in FIG. 8C. Good.

さらにまた、円形溝部４２にて円形ベースポット３０を９０度回転させたが、９０度まで回転させなくとも、円形ベースポット３０をある程度の角度まで回転させるだけで、嵌合凸部３３ａは円形溝部４２によって位置規制される。しかし、回転角度が少ない場合、何かの拍子に回転移動が戻り、円形溝部４２による位置規制が解消される可能性があるため、３０度以上１５０度以下で回転させることが好ましい。 Furthermore, although the circular base spot 30 was rotated by 90 degrees in the circular groove portion 42, the fitting convex portion 33a is formed by the circular groove portion only by rotating the circular base spot 30 to a certain angle without rotating it to 90 degrees. Position regulated by 42. However, when the rotation angle is small, the rotational movement may return to some beat and the position restriction by the circular groove portion 42 may be canceled. Therefore, it is preferable to rotate at 30 degrees or more and 150 degrees or less.

なお、円形溝部４２を平面視円形に形成せずとも、ベースポット本体３３に形成された嵌合凸部３３ａを嵌入及び規制することができるものであれば、例えばひし形や多角形であってもよく、その形状は問わない。具体的には、例えば、図８（ｄ）乃至図８（ｆ）に示すように、奥行方向Ｌに対して斜め方向に向いた平面視略鼓形状の鼓形溝部４２ａを設けてよい。 It should be noted that, as long as the fitting convex portion 33a formed on the base spot main body 33 can be fitted and regulated without forming the circular groove portion 42 in a circular shape in a plan view, for example, a rhombus or a polygon may be used. Well, the shape does not matter. Specifically, for example, as shown in FIGS. 8 (d) to 8 (f), a drum-shaped groove portion 42a having a substantially drum-shaped plan view facing diagonally with respect to the depth direction L may be provided.

この場合、図８（ｄ）に示すように、嵌合溝４１が配置された側に円形ベースポット３０を配置し、図８（ｅ）に示すように、嵌合凸部３３ａを嵌合溝４１で鼓形溝部４２ａまで案内し、図８（ｆ）に示すように、鼓形溝部４２ａにて円形ベースポット３０を鼓形溝部４２ａの形状に合わせて回転させて、鼓形溝部４２ａにおいて円形ベースポット３０の位置を規制してもよい。 In this case, as shown in FIG. 8 (d), the circular base spot 30 is arranged on the side where the fitting groove 41 is arranged, and as shown in FIG. 8 (e), the fitting convex portion 33a is provided in the fitting groove. Guided to the drum-shaped groove portion 42a by 41, as shown in FIG. 8 (f), the circular bass spot 30 is rotated in the drum-shaped groove portion 42a according to the shape of the drum-shaped groove portion 42a, and the circular base spot 30 is rotated in the drum-shaped groove portion 42a. The position of the base pot 30 may be restricted.

また、単に、円形溝部４２で円形ベースポット３０を回転させて、円形溝部４２で円形ベースポット３０の位置を規制するだけでなく、図９（ａ）乃至図９（ｄ）に示すように、回転移動させた円形ベースポット３０を別部材で固定してもよい。 Further, not only the circular base spot 30 is rotated by the circular groove portion 42 to regulate the position of the circular base spot 30 by the circular groove portion 42, but also as shown in FIGS. 9 (a) to 9 (d), The rotationally moved circular base spot 30 may be fixed by another member.

具体的には、ベースプレート４０における円形溝部４２の幅方向Ｗの側方に、外部から固定ピン５０を挿着できる挿着孔４４を設けるとともに、ベースポット本体３３における対応する円弧部分にも、固定ピン５０が挿入される挿入凹部３５を設ける。さらには、円形溝部４２における幅方向Ｗの中央における奥行方向Ｌにも三角表示４３ａを設ける。 Specifically, an insertion hole 44 into which the fixing pin 50 can be inserted from the outside is provided on the side of the circular groove portion 42 in the base plate 40 in the width direction W, and is also fixed to the corresponding arc portion in the base spot main body 33. An insertion recess 35 into which the pin 50 is inserted is provided. Further, a triangular display 43a is also provided in the depth direction L at the center of the width direction W in the circular groove portion 42.

図９（ａ）乃至図９（ｃ）に示すように、上述の説明通り、嵌合溝４１で嵌合凸部３３ａを円形溝部４２まで案内するとともに、円形溝部４２で回転させる。このとき、三角表示４３ａと円形ベースポット３０に設けた三角表示３４と合わせることによって、図９（ｃ）に示すように、挿入凹部３５と挿着孔４４との位置が略一致するため、挿着孔４４を貫通させて挿入凹部３５に固定ピン５０を挿入して、円形ベースポット３０の回転状態を固定することができる。 As shown in FIGS. 9A to 9C, the fitting convex portion 33a is guided to the circular groove portion 42 by the fitting groove 41 and rotated by the circular groove portion 42 as described above. At this time, by combining the triangular display 43a with the triangular display 34 provided on the circular base spot 30, the positions of the insertion recess 35 and the insertion hole 44 are substantially the same as shown in FIG. 9C. The rotating state of the circular base spot 30 can be fixed by inserting the fixing pin 50 into the insertion recess 35 through the hole 44.

なお、円形ベースポット３０を回転移動させずとも、嵌合凸部３３ａの幅方向Ｗの側方に挿入凹部３５を設け、所定位置まで嵌入された円形ベースポット３０の嵌合凸部３３ａに設けられた挿入凹部３５に固定ピン５０を挿入してベースプレート４０に対する円形ベースポット３０の位置を位置規制するように構成してもよい。 Even if the circular base spot 30 is not rotationally moved, the insertion recess 35 is provided on the side of the fitting convex portion 33a in the width direction W, and is provided in the fitting convex portion 33a of the circular base spot 30 fitted to a predetermined position. The fixing pin 50 may be inserted into the inserted recess 35 to regulate the position of the circular base spot 30 with respect to the base plate 40.

例えば、上述の説明では、下部建造物１００の上面において水平に固定したベースプレート４０に対して水平な嵌合溝４１を設けたが、円形溝部４２に向かって嵌合溝４１を傾斜させてもよい。
また、嵌合溝４１及び円形溝部４２を有するベースプレート４０、並びに嵌合凸部３３ａを有する円形ベースポット３０を下沓３に設けたが、これらを上沓２に設けてもよいし、上沓２と下沓３の両方に設けてもよい。なお、嵌合溝４１及び円形溝部４２並びに嵌合凸部３３ａを有する円形ベースポット３０を上沓２に設ける場合、単に溝と凸部とを嵌合させてスライドさせるだけでなく、嵌合溝４１や円形溝部４２を被係合形状で構成するとともに、嵌合溝４１や円形溝部４２に係合できる係合形状で嵌合凸部３３ａを形成すればよい。 For example, in the above description, the fitting groove 41 horizontal to the base plate 40 fixed horizontally on the upper surface of the lower building 100 is provided, but the fitting groove 41 may be inclined toward the circular groove portion 42. ..
Further, although the base plate 40 having the fitting groove 41 and the circular groove portion 42 and the circular base spot 30 having the fitting convex portion 33a are provided on the lower shoe 3, these may be provided on the upper shoe 2 or the upper shoe. It may be provided in both 2 and the lower shoe 3. When the circular base spot 30 having the fitting groove 41, the circular groove portion 42, and the fitting convex portion 33a is provided on the upper sill 2, the fitting groove is not only slid by fitting the groove and the convex portion, but also the fitting groove. The fitting convex portion 33a may be formed in an engaged shape so that the 41 and the circular groove portion 42 can be engaged with the fitting groove 41 and the circular groove portion 42.

また、上述の説明では、ベースプレート４０に嵌合溝４１を形成し、ベースポット本体３３に嵌合凸部３３ａを形成する構成としたが、ベースプレート４０に嵌合凸部を形成し、ベースポット本体３３に嵌合溝を形成する構成としてもよい。この場合、嵌合溝が形成された円形ベースポット３０を嵌合凸部が形成されたベースプレート４０に嵌め入れることにより、円形ベースポット３０を所定の角度回転させることなく円形ベースポット３０の移動を抑制することができる。 Further, in the above description, the fitting groove 41 is formed in the base plate 40 and the fitting convex portion 33a is formed in the base plate main body 33, but the fitting convex portion is formed in the base plate 40 and the base spot main body is formed. A fitting groove may be formed in 33. In this case, by fitting the circular base plate 30 having the fitting groove formed into the base plate 40 having the fitting convex portion formed, the circular base spot 30 can be moved without rotating the circular base spot 30 by a predetermined angle. It can be suppressed.

また、上述の説明では、円形溝部４２で円形ベースポット３０を回転させて、その位置を位置規制したが、所定位置まで嵌入された円形ベースポット３０を幅方向Ｗに移動させて、その位置を位置規制するように構成してもよいし、円形溝部４２で円形ベースポット３０を回転させるとともに、さらに幅方向Ｗに移動させて、位置規制をより確実なものにするよう構成してもよい。 Further, in the above description, the circular base spot 30 is rotated by the circular groove portion 42 to regulate the position, but the circular base spot 30 fitted to the predetermined position is moved in the width direction W to move the position. The position may be regulated, or the circular base spot 30 may be rotated by the circular groove 42 and further moved in the width direction W to make the position regulation more reliable.

また、上沓２をベースプレート４０と円形ベースポット３０とで構成し、下沓３を固定プレート２１とスライドプレート２２とで構成して支承装置１を構成してもよい。
さらにまた、ベースプレート４０を設けることなく、下部建造物１００の上面又は上部建造物１１０の底面のいずれかに嵌合溝４１及び円形溝部４２を形成してもよい。 Further, the upper shoe 2 may be composed of the base plate 40 and the circular base plate 30, and the lower shoe 3 may be composed of the fixing plate 21 and the slide plate 22 to form the bearing device 1.
Furthermore, the fitting groove 41 and the circular groove portion 42 may be formed on either the upper surface of the lower structure 100 or the lower surface of the upper structure 110 without providing the base plate 40.

また上述の説明では、嵌入手段としてベースプレート４０に対してベースポット本体３３を嵌入できるように、ベースプレート４０に嵌合溝４１及び円形溝部４２を形成するとともに、ベースポット本体３３の底面に嵌合凸部３３ａを設けたが、嵌合溝４１、円形溝部４２並びに嵌合凸部３３ａの代わりに、係合し合う被係合部と係合部などで構成してもよい。 Further, in the above description, the fitting groove 41 and the circular groove portion 42 are formed in the base plate 40 so that the base plate 40 can be fitted into the base plate 40 as a fitting means, and the fitting protrusion is formed on the bottom surface of the base plate body 33. Although the portion 33a is provided, instead of the fitting groove 41, the circular groove portion 42, and the fitting convex portion 33a, it may be composed of an engaged portion and an engaging portion that engage with each other.
