Description

本発明は、免震建物等の免震構造物と、その周囲に位置する地盤又は非免震構造物との間に設けられる免震構造物の伸縮柵に関するものである。   The present invention relates to a telescopic fence for a base isolation structure provided between a base isolation structure such as a base isolation building and a ground or a non-base isolation structure located around the base isolation structure.

近年、地震による被害を最小限にするために、免震構造物が広く採用されるようになった。この免震構造物は、基礎部分に積層ゴムアイソレータを設け、この積層ゴムアイソレータの上に構造物を建設するものであり、積層ゴムアイソレータにより地震の固有振動周期を長周期化して免震効果を得ようとするものである。このような免震構造物は、地震の際、地盤の揺れに追随せず水平方向へ揺れるものであるので、免震構造物と、その周囲の地盤との間には、溝状の間隙が設けられている。そして、この間隙には、免震構造物と地盤との往来を可能とするために、渡り廊下が設けられている。   In recent years, seismic isolation structures have been widely adopted to minimize damage from earthquakes. This seismic isolation structure is constructed by providing a laminated rubber isolator on the foundation and constructing the structure on top of this laminated rubber isolator. By the laminated rubber isolator, the natural vibration period of the earthquake is lengthened and the seismic isolation effect is obtained. I want to get it. Such a seismic isolation structure does not follow the shaking of the ground in the event of an earthquake, but swings in the horizontal direction, so there is a groove-like gap between the seismic isolation structure and the surrounding ground. Is provided. In this gap, a crossing corridor is provided in order to allow the seismic isolation structure and the ground to come and go.

以上のような免震構造物においては、免震構造物と地盤との間に侵入防止等の目的で柵が設けられたり、また、渡り廊下の側部において転落防止等の目的で柵が設けられている。このような柵は、地震時において、免震構造物が水平方向に揺れるので、水平方向の変形に追随できるように伸縮可能に構成されており、免震構造側に回動自在に連結されたユニット（パネル体）と、非免震構造側に回動自在に連結されたユニット（パネル体）との２枚のユニット（パネル体）を、それらの一部が重複するとともに平行に移動自在に配置されたものがある（特許文献１参照）。   In the seismic isolation structure as described above, a fence is provided between the seismic isolation structure and the ground for the purpose of preventing intrusion or the like, and a fence is provided on the side of the passageway for the purpose of preventing the fall. ing. Such a fence is configured to be stretchable so that it can follow the deformation in the horizontal direction because the seismic isolation structure shakes in the horizontal direction during an earthquake, and is pivotally connected to the seismic isolation structure side. Two units (panel bodies) consisting of a unit (panel body) and a unit (panel body) rotatably connected to the non-seismic isolation structure side can be moved in parallel while part of them overlap. Some are arranged (see Patent Document 1).

このような２枚のパネル体からなる伸縮柵においては、２枚のパネル体が平行方向に移動自在となるように連結しなければならず、この連結構造としては、例えば、２枚のパネル体（カバープレート）の上部に設けられた支持バーを支持ホルダーで被嵌する構造や（特許文献２参照）、２枚のパネル体（手摺ユニット）上下に設けられた横枠杆にスライド芯材を嵌合させた構造や（特許文献３参照）、２枚のパネル体（目隠しパネル）の一方にレールを形成するとともに、このレールに、他方のパネル体に取付けたローラーを遊嵌させた構造が提案されていた（特許文献４参照）。   In such a telescopic fence composed of two panel bodies, the two panel bodies must be connected so as to be movable in the parallel direction. As this connection structure, for example, two panel bodies A structure in which a support bar provided on the upper part of the (cover plate) is fitted with a support holder (see Patent Document 2), and a slide core material is attached to horizontal frame rods provided above and below two panel bodies (handrail units). A structure in which a rail is formed on one of two panel bodies (blindfolded panels) and a roller attached to the other panel body is loosely fitted on the rail. It has been proposed (see Patent Document 4).

特許第３８５５１９２号公報Japanese Patent No. 3855192 特開２００３−１６６３２４号公報JP 2003-166324 A 特許第３７０８４２０号公報Japanese Patent No. 3708420 特開平２００１−２２７０７３号公報Japanese Patent Laid-Open No. 2001-227073

しかしながら、特許文献２で提案されている支持バーを支持ホルダーで被嵌する連結構造は、支持バーと支持ホルダーとが接触状態で摺動するものであるので、円滑に移動させることが出来ず、特許文献３で提案されている横枠杆にスライド芯材を嵌合させた連結構造も、横枠杆とスライド芯材とが接触状態で摺動するものであるので、円滑に移動させることが出来ないものであった。   However, since the connection structure in which the support bar proposed in Patent Document 2 is fitted with the support holder slides in a contact state between the support bar and the support holder, it cannot be moved smoothly. The connection structure in which the slide core material is fitted to the horizontal frame rod proposed in Patent Document 3 is also a structure in which the horizontal frame rod and the slide core material slide in contact with each other, and thus can be moved smoothly. It was not possible.

特許文献４で提案されているレールにローラーを遊嵌させた連結構造は、円滑に移動させることはできるが、一方のパネル体の先端近傍にのみローラーを設けたものであるので、パネル体の水平方向の長さが長いと、パネル体は片持ち式であるので、自重により先端側は下降するものであった。   The connection structure in which the roller is loosely fitted to the rail proposed in Patent Document 4 can be moved smoothly, but the roller is provided only in the vicinity of the tip of one panel body. When the length in the horizontal direction is long, the panel body is cantilevered, so that the tip side descends due to its own weight.

本発明は以上の問題点を解決し、２枚のパネル体にそれぞれガイド溝を設けるとともに、２枚のパネル体の先端近傍にそれぞれローラーを設け、各ローラーを対応するガイド溝内を走行させることにより、パネル体を円滑に移動させることができるとともに、パネル体の先端側が下降、すなわちパネル体が傾くのを防止できるようにした免震構造物の伸縮柵を提供することを目的とする。   The present invention solves the above-described problems, and each of the two panel bodies is provided with a guide groove, and each of the two panel bodies is provided with a roller near the tip, and each roller is caused to travel within the corresponding guide groove. Thus, an object of the present invention is to provide a telescopic fence for a seismic isolation structure that can smoothly move the panel body and prevent the front end side of the panel body from descending, that is, the panel body from tilting.

請求項１に掛かる免震構造物の伸縮柵は、免震構造物又は免震構造物が建設された基礎上に設置された支柱に水平方向に回動自在に連結された免震側パネル体と、非免震構造物又は非免震基礎上に設置された支柱に水平方向に回動自在に連結された非免震側パネル体とからなり、前記免震側パネル体と非免震側パネル体とが一部重複するとともに平行に移動自在に配置された伸縮柵であって、前記免震側パネル体の上下枠の先端近傍に設けられた免震側ローラーと、前記非免震側パネル体の上下枠の先端近傍に設けられた非免震側ローラーと、前記免震側パネル体の上下枠に形成され非免震側ローラーが走行する免震側ガイド溝と、前記非免震側パネル体の上下枠に形成され免震側ローラーが走行する非免震側ガイド溝とを有し、前記免震側ローラー及び非免震側ローラーの外周部の断面形状が略台形状に形成されるとともに、免震側ガイド溝及び非免震側ガイド溝の形状が、免震側ローラー及び非免震側ローラーの外周部が嵌合する台形状に形成されていることを特徴として構成されている。 The telescopic fence of the seismic isolation structure according to claim 1 is a seismic isolation side panel body that is pivotally connected in a horizontal direction to a column installed on the base where the seismic isolation structure or the base isolation structure is constructed. If consists of a non-seismic isolation structure or Himen Shin Himen is pivotally connected to the horizontally installed struts on a foundation Shingawa panel body, the seismic isolation side panel member and Himen Shin side A telescopic fence partially overlapped with the panel body and arranged to be movable in parallel, the seismic isolation side roller provided near the top end of the upper and lower frames of the seismic isolation side panel body, and the non-isolation side A non-isolation-side roller provided near the top end of the upper and lower frame of the panel body, a seismic isolation-side guide groove formed on the upper and lower frame of the seismic isolation-side panel body and traveled by the non-isolation-side roller, and the non-seismic isolation possess a Himen Shingawa guide groove seismic isolation side roller are formed on upper and lower frames of the side panel member travels, the MenShingawa The cross-sectional shape of the outer periphery of the roller and the non-seismic isolation side roller is formed in a substantially trapezoidal shape, and the shape of the seismic isolation side guide groove and the non-seismic isolation side guide groove is the outer peripheral portion is formed as a feature that you have been formed in a trapezoidal shape to be fitted.

請求項１に係る免震構造物の伸縮柵においては、免震側ローラーが非免震側ガイド溝を走行するとともに、非免震側ローラーが免震側ガイド溝を走行するようになっているので、各パネル体は先端近傍と、一方のローラーが位置する中間部とで支持されることとなるので、パネル体の傾きを防止している。   In the telescopic fence of the seismic isolation structure according to claim 1, the seismic isolation side roller travels in the non-isolation side guide groove, and the non-seismic isolation side roller travels in the seismic isolation side guide groove. Therefore, each panel body is supported by the vicinity of the tip and the intermediate portion where one roller is positioned, thereby preventing the panel body from being inclined.

また、パネル体の先端近傍に設けられたローラーは、他方のパネル体の中間部において係合しているので、パネル体の先端が下降するのを防止することができる。すなわち、パネル体は、先端に行くにしたがって下降の程度が大きくなるものであり、中間部における下降長さは、先端における下降長さより小さいものである。したがって、先端近傍に設けられたローラーは、先端近傍における下降長さより小さい下降長さの中間部においてガイド溝と係合するので、ローラーの下降（先端近傍の下降）は中間部のガイド溝により妨げられ、それ以上下降しないものである。その結果、パネル体の傾斜を有効に防止できる。   Moreover, since the roller provided near the front-end | tip of a panel body is engaging in the intermediate part of the other panel body, it can prevent that the front-end | tip of a panel body falls. That is, the panel body has a degree of lowering as it goes to the tip, and the lowering length at the intermediate portion is smaller than the lowering length at the tip. Accordingly, the roller provided in the vicinity of the tip engages with the guide groove at the middle portion of the lowering length smaller than the lowering length in the vicinity of the tip, so that the lowering of the roller (lowering in the vicinity of the tip) is hindered by the guide groove in the middle portion. It will not descend any further. As a result, the inclination of the panel body can be effectively prevented.

なお、一方のパネル体の先端近傍と中間部とにローラーを設けた場合、中間部に設けたローラーは、他方のパネル体の先端近傍のガイド溝と係合し、当該ガイド溝はローラーの下降長さより長いものであるので、ローラーは抵抗無く下降するものである。   In addition, when a roller is provided in the vicinity of the tip of one panel body and the middle part, the roller provided in the middle part engages with a guide groove in the vicinity of the tip of the other panel body, and the guide groove is lowered by the roller. Since it is longer than the length, the roller descends without resistance.

また、ローラーが先端近傍に設けられているので、伸張時において長い距離を確保することが出来る。すなわち、免震側パネル体と非免震側パネル体とを合計した長さに近い長さにまで伸張させることが出来る。   Moreover, since the roller is provided in the vicinity of the tip, a long distance can be ensured during extension. That is, it can be extended to a length close to the total length of the base isolation side panel body and the non-base isolation side panel body.

さらに、免震側ローラー及び非免震側ローラーの外周部の断面形状が略台形上に形成されるとともに、免震側ガイド溝及び非免震側ガイド溝の形状が、免震側ローラー及び非免震側ローラーの外周部が嵌合する台形状に形成されているので、パネル体が横揺れした場合であっても、ガイド溝によりローラーが外れるのを防止することが出来るとともに、円滑な走行を確保することが出来る。
 Furthermore, the cross-sectional shape of the outer periphery of the seismic isolation side roller and the non-isolation side roller is formed on a substantially trapezoidal shape, and the shape of the seismic isolation side guide groove and the non-isolation side guide groove is the seismic isolation side roller and the non-isolation side roller. Since the outer periphery of the seismic isolation side roller is formed in a trapezoidal shape, it is possible to prevent the roller from coming off by the guide groove even when the panel body rolls , and smooth running Can be secured.

本発明の免震構造物の伸縮柵は、前記免震側パネル体の上下枠の先端近傍に設けられた免震側ローラーと、前記非免震側パネル体の上下枠の先端近傍に設けられた非免震側ローラーと、前記免震側パネル体の上下枠に形成され非免震側ローラーが走行する免震側ガイド溝と、前記非免震側パネル体の上下枠に形成され免震側ローラーが走行する非免震側ガイド溝とが設けられ、免震側パネル体の上下枠の先端近傍に設けられた免震側ローラーが、非免震側パネル体に形成した非免震側ガイド溝に係合して走行するとともに、非免震側パネル体の上下枠の先端近傍に設けられた非免震側ローラーが、免震側パネル体に形成した免震側ガイド溝に係合して走行するようになっている。したがって、パネル体が円滑に摺動するとともに、パネル体が傾斜するのを防止することができる。   The telescopic fence of the seismic isolation structure according to the present invention is provided near the tip of the upper and lower frames of the non-isolation side panel body and the seismic isolation side roller provided in the vicinity of the top and bottom frames of the seismic isolation side panel body. Non-isolation-side rollers, seismic isolation-side guide grooves formed on the upper and lower frames of the seismic isolation-side panel body and traveled by the non-isolation-side rollers, and seismic isolation formed on the upper and lower frames of the non-isolation-side panel body A non-isolation side guide groove is provided on the non-isolation side panel body. The non-isolation side roller provided near the top of the upper and lower frames of the non-isolation side panel body engages with the isolation groove on the seismic isolation side panel body. And is supposed to run. Therefore, the panel body can be smoothly slid and the panel body can be prevented from being inclined.

これらのローラー及びガイド溝は特に限定されるものでないが、ローラーがガイド溝が外れない構成にすることが好ましい、例えば、免震側ガイド溝及び非免震側ガイド溝が、免震側ローラー及び非免震側ローラーの外側面に当接するように、凹状に形成することが出来き、また、ローラーの外周部の断面形状とガイド溝との形状を略同一にすることにより、ローラーが外れるのをより防止することができる。例えば、免震側ローラー及び非免震側ローラーの外周部の断面形状を略台形上に形成したり、円弧状に形成したり、矩形状に形成し、ガイド溝はこれらの形状に対応して略同一形状及び寸法で形成する。また、ローラーの取付け位置は、先端に近い位置に取り付ける程、伸張時の長さを長く取ることができる。   These rollers and guide grooves are not particularly limited, but it is preferable that the rollers have a configuration in which the guide grooves are not removed. For example, the seismic isolation side guide grooves and the non-isolation side guide grooves are the seismic isolation side rollers and It can be formed in a concave shape so as to contact the outer surface of the non-seismic isolation roller, and the roller can be removed by making the cross-sectional shape of the outer periphery of the roller substantially the same as the shape of the guide groove. Can be prevented more. For example, the cross-sectional shape of the outer periphery of the seismic isolation side roller and the non-seismic isolation side roller is formed on a substantially trapezoidal shape, an arc shape, or a rectangular shape, and the guide groove corresponds to these shapes. It is formed with substantially the same shape and dimensions. Further, as the roller is attached to a position closer to the tip, the length at the time of extension can be increased.

本発明の免震構造物の伸縮柵の一実施形態を図面を参照して説明する。   One embodiment of the telescopic fence of the seismic isolation structure of this invention is described with reference to drawings.

図１〜図３において、１は免震構造物の伸縮柵で、免震構造物が建設された基礎側の地面２に設置された免震側支柱２１と、非免震側の地面３に設置された非免震側支柱３１との間に設けられている。免震構造物の伸縮柵１は、免震側支柱２１に継手２２で水平方向に回動自在に連結された免震側パネル体４０と、非免震側支柱３１に継手３２で水平方向に回動自在に連結された非免震側パネル体５０とが設けられ、これら免震側パネル４０と非免震側パネル５０とは、先端から中央部までが互いに重複した状態で平行に配置され、その長手方向に進退自在となっている。   In FIG. 1 to FIG. 3, reference numeral 1 denotes a telescopic fence of a seismic isolation structure, on the seismic isolation side column 21 installed on the ground 2 on the foundation side where the seismic isolation structure was constructed, and on the ground 3 on the non-seismic isolation side It is provided between the installed non-seismic isolation post 31. The telescopic fence 1 of the seismic isolation structure includes a seismic isolation side panel body 40 that is pivotably coupled to the seismic isolation side column 21 by a joint 22 in a horizontal direction and a non-isolation side column 31 at a joint 32 in a horizontal direction. A non-seismic isolation side panel body 50 that is rotatably connected is provided, and the seismic isolation side panel 40 and the non-seismic isolation side panel 50 are arranged in parallel with each other from the tip to the center. , Can move forward and backward in the longitudinal direction.

免震側パネル体４０は、上枠４１、下枠４２、基部側縦枠４３及び先端側縦枠４４で矩形の枠が形成され、これらの内側に複数の縦格子４５が形成されるとともに、潜り戸４６が形成されている。そして、基部側縦枠４３が前記継手２２に連結されることにより、免震側支柱２１に片持ち状に取り付けられている。なお、４７は潜り戸４６の錠である。   In the seismic isolation side panel body 40, a rectangular frame is formed by an upper frame 41, a lower frame 42, a base side vertical frame 43, and a tip side vertical frame 44, and a plurality of vertical lattices 45 are formed inside these, A sliding door 46 is formed. The base side vertical frame 43 is connected to the joint 22 to be attached to the seismic isolation side column 21 in a cantilever manner. Reference numeral 47 denotes a lock for the sliding door 46.

非免震側パネル体５０も、免震側パネル体４０と同様に、上枠５１、下枠５２、基部側縦枠５３及び先端側縦枠５４で矩形の枠が形成され、これらの内側に複数の縦格子５５が形成されている。そして、基部側縦枠５３が前記継手３２に連結されることにより、非免震側支柱３１に片持ち状に取り付けられている。   Similarly to the seismic isolation side panel body 40, the non-seismic isolation side panel body 50 is also formed with a rectangular frame with an upper frame 51, a lower frame 52, a base side vertical frame 53, and a distal end side vertical frame 54, and inside these frames, A plurality of vertical lattices 55 are formed. The base side vertical frame 53 is connected to the joint 32 so as to be cantilevered to the non-seismic isolation side column 31.

免震側パネル体４０の上枠４１及び下枠４２の先端近傍には、免震側ローラー６０が非免震側パネル体５０方向へ突出して設けられており、非免震側パネル体５０の上枠５１及び下枠５２の先端近傍にも、同様に、非免震側ローラー７０が免震側パネル体４０方向へ突出して設けられている。また、免震側パネル体４０の上枠４１及び下枠４２の非免震側パネル体５０と対向する面には、免震側ガイド溝４８が形成され、非免震側パネル体５０の上枠５１及び下枠５２の免震側パネル体４０と対向する面にも、同様に、非免震側ガイド溝５６が形成されている。   Near the top ends of the upper frame 41 and the lower frame 42 of the seismic isolation side panel body 40, a seismic isolation side roller 60 is provided so as to protrude toward the non-seismic isolation side panel body 50. Similarly, a non-seismic isolation side roller 70 is provided in the vicinity of the top ends of the upper frame 51 and the lower frame 52 so as to protrude toward the seismic isolation side panel body 40. A seismic isolation side guide groove 48 is formed on the surface of the upper frame 41 and the lower frame 42 of the seismic isolation side panel body 40 facing the non-isolation side panel body 50, Similarly, non-isolation-side guide grooves 56 are formed on the surfaces of the frame 51 and the lower frame 52 facing the isolation-side panel body 40.

そして、図４に示すように、免震側ローラー６０は、非免震側ガイド溝５６に挿入されて走行自在となっており、その回転軸が軸受け６１を介して上枠４１及び下枠４２に回転自在に設けられ、非免震側ローラー７０も、同様に、免震側ガイド溝４８に挿入されて走行自在となっており、その回転軸が軸受け７１を介して上枠５１及び下枠５２に回転自在に設けられている。また、免震側ローラー６０及び非免震側ローラー７０の外周部の断面形状は略台形状に形成されるとともに、免震側ガイド溝４８及び非免震側ガイド溝５６の形状が、免震側ローラー６０及び非免震側ローラー７０の外周部の断面形状と略同一な台形状に形成され、免震側ローラー６０及び非免震側ローラー７０の外周部が、免震側ガイド溝４８及び非免震側ガイド溝５６に略嵌合した状態となっている。   As shown in FIG. 4, the seismic isolation side roller 60 is inserted into the non-seismic isolation side guide groove 56 so as to be able to travel, and the rotation axis thereof is supported by the upper frame 41 and the lower frame 42 via a bearing 61. Similarly, the non-seismic isolation side roller 70 is also inserted into the seismic isolation side guide groove 48 so that it can run freely, and its rotation axis is connected to the upper frame 51 and the lower frame via a bearing 71. 52 is rotatably provided. Further, the cross-sectional shapes of the outer peripheral portions of the seismic isolation side roller 60 and the non-seismic isolation side roller 70 are formed in a substantially trapezoidal shape, and the shapes of the seismic isolation side guide groove 48 and the non-seismic isolation side guide groove 56 are It is formed in the trapezoid shape substantially the same as the cross-sectional shape of the outer peripheral part of the side roller 60 and the non-seismic isolation side roller 70, and the outer peripheral part of the seismic isolation side roller 60 and the non-seismic isolation side roller 70 is the seismic isolation side guide groove 48 and The non-seismic isolation side guide groove 56 is substantially fitted.

以上のような免震構造物の伸縮柵１においては、地震が発生して免震側支柱２１と非免震側支柱３１との相対的な位置関係が変動（伸張又は収縮）すると、免震側パネル体４０と非免震側パネル体５０との伸張又は収縮に伴い、免震側ローラー６０と非免震側ローラー７０とが非免震側ガイド溝５６と免震側ガイド溝４８内を走行する。したがって、免震側パネル体４０と非免震側パネル体５０とは円滑に変動に追随することができる。   In the telescopic fence 1 of the base isolation structure as described above, if an earthquake occurs and the relative positional relationship between the base isolation side column 21 and the non-base isolation side column 31 fluctuates (extends or contracts), the base isolation is performed. As the side panel body 40 and the non-isolation side panel body 50 expand or contract, the isolation base roller 60 and the non-isolation side roller 70 move in the non-isolation side guide groove 56 and the isolation base guide groove 48. Run. Therefore, the seismic isolation side panel body 40 and the non-base isolation side panel body 50 can smoothly follow fluctuations.

また、免震側パネル体４０と非免震側パネル体５０とが大きく伸張した場合であっても、それぞれの先端近傍に設けた免震側ローラー６０と非免震側ローラー７０とがそれぞれ他方から支持されているので、大きく傾くことが無い。さらに、免震側パネル体４０と非免震側パネル体５０とが大きく水平方向に揺れた場合であっても、免震側ローラー６０と非免震側ローラー７０とは、それぞれ走行する非免震側ガイド溝５６と免震側ガイド溝４８とにより水平方向の動きが規制されるので、確実に平行状態を維持することが出来る。   Moreover, even if the seismic isolation side panel body 40 and the non-seismic isolation side panel body 50 extend | stretched largely, the seismic isolation side roller 60 and the non-seismic isolation side roller 70 which were provided in the vicinity of each front-end | tip respectively Because it is supported from, it does not tilt greatly. Furthermore, even if the seismic isolation side panel body 40 and the non-seismic isolation side panel body 50 are greatly swayed in the horizontal direction, the seismic isolation side roller 60 and the non-seismic isolation side roller 70 are not driven. Since the movement in the horizontal direction is restricted by the seismic guide groove 56 and the seismic isolation guide groove 48, the parallel state can be reliably maintained.
