Description

本発明は、中間部に免震装置を有する免震建物に用いられるエレベータの乗場ドア設置構造に関するものである。   The present invention relates to a landing door installation structure for an elevator used in a seismic isolation building having a seismic isolation device in an intermediate part.

免震建物は、中間部に免震装置を設け、地震発生時には免震装置の上方階床と下方階床との間の水平方向における相対変位を許容して地震エネルギーを分散させ、これにより構造物の損壊を防止しようとするものである。このような免震建物に設置されるエレベータ設備では、免震装置が設けられている階床(免震層階)とその直ぐ上の階床(上方隣接階)との間の大きな相対変位により昇降路も変形することになる。このときの昇降路の変形により、ガイドレールと乗場ドアとの間の距離が大きく変化すると、これらの階床におけるエレベータかごの通過やエレベータかごに対する乗客の乗降が不可能になる。したがって、免震建物に設置されるエレベータ設備では、免震層階及び上方隣接階におけるガイドレールとエレベータかごとの間の距離を極力変化させない構造とすることが要求される(例えば、特許文献1参照)。   The seismic isolation building has a seismic isolation device in the middle, and in the event of an earthquake, the seismic energy is distributed by allowing relative displacement in the horizontal direction between the upper floor and the lower floor of the seismic isolation device. It is intended to prevent damage to things. In an elevator installation installed in such a base-isolated building, due to a large relative displacement between the floor where the base isolation device is installed (the base isolation layer) and the floor immediately above it (the upper adjacent floor). The hoistway will also be deformed. If the distance between the guide rail and the landing door changes greatly due to the deformation of the hoistway at this time, it becomes impossible for the elevator cars to pass through these floors and passengers to get on and off the elevator cars. Therefore, an elevator installation installed in a base-isolated building is required to have a structure in which the distance between the guide rail and the elevator car in the base isolation floor and the upper adjacent floor is not changed as much as possible (for example, Patent Document 1). reference).

図10は、この特許文献1に開示された従来技術の説明図である。この図において、基礎51に低層部52が建設され、この低層部52の上方に免震装置53を介して高層部54が建設されている。これら低層部52及び高層部54の中央部には、垂直方向に内部を貫通する昇降路55が形成されている。昇降路55の内部にはガイドレール56が設けられ、このガイドレール56に沿ってかご57が昇降路55内を昇降動するようになっている。   FIG. 10 is an explanatory diagram of the prior art disclosed in Patent Document 1. In FIG. In this figure, a low-rise part 52 is constructed on a foundation 51, and a high-rise part 54 is constructed above the low-rise part 52 via a seismic isolation device 53. A hoistway 55 penetrating through the inside in the vertical direction is formed in the central portion of the low layer portion 52 and the high layer portion 54. A guide rail 56 is provided inside the hoistway 55, and a car 57 moves up and down in the hoistway 55 along the guide rail 56.

そして、免震装置53を中心とする上下方向には、昇降支柱体58が昇降路55内に設けられている。昇降支柱体58の下部側は拘束材59,60により昇降路壁61に固定されている。また、この昇降支柱体58には乗場ドア62が設けられている。   A lifting column body 58 is provided in the hoistway 55 in the vertical direction centering on the seismic isolation device 53. The lower side of the lifting column body 58 is fixed to the hoistway wall 61 by restraining members 59 and 60. Further, a landing door 62 is provided on the lifting column body 58.

免震装置53を中心とする昇降支柱体58の低層部側高さH1及び高層部側高さH2は等しくなっており、昇降支柱体58と低層部側及び高層部側昇降路壁61との間の各クリアランスはL1,L2となっている。   The lower layer side height H1 and the higher layer side height H2 of the lifting column body 58 centering on the seismic isolation device 53 are equal, and the lifting column body 58 and the lower layer side and higher layer side hoistway wall 61 are The clearances between them are L1 and L2.

そして、地震発生時には昇降支柱体58が変形すると共に、免震装置53の働きにより高層部側と低層部側との間に相対変位が生じ、高層部54の最大変位位置は破線で示す位置となる。クリアランスはL1,L2の値は、このときの高層部54の変位量L0の2分の1とすることができる。
特開平10−88847号公報
When the earthquake occurs, the lifting column 58 is deformed, and the seismic isolation device 53 causes relative displacement between the high-rise part and the low-rise part. The maximum displacement position of the high-rise part 54 is the position indicated by the broken line. Become. The clearances L1 and L2 can be set to a half of the displacement L0 of the high-rise portion 54 at this time.
JP-A-10-88847

しかし、図10に示したような、昇降路55内に昇降支柱体58を配設する構成とすると、昇降支柱体58の配設分だけ昇降路55の横断面積を大きくしなければならず、しかも、このような大きな横断面積の昇降路55を有する階床は複数階床(図10のH1,H2の範囲の階床)にわたることになる。したがって、その分だけ建物内における有効利用可能な床面積が削減されることになり、建物の価値の低下につながることになる。このようなことから、特許文献1のような昇降支柱体を用いる構成は、主として大規模なビルのみに適用され、中規模以下のビルに適用されることは余りなかった。   However, when the hoisting column body 58 is disposed in the hoistway 55 as shown in FIG. 10, the cross-sectional area of the hoistway 55 must be increased by the amount of the hoisting column body 58 disposed. Moreover, the floor having the hoistway 55 having such a large cross-sectional area extends over a plurality of floors (floors in the range of H1 and H2 in FIG. 10). Therefore, the floor area that can be effectively used in the building is reduced by that amount, leading to a decrease in the value of the building. For this reason, the configuration using the lifting column as in Patent Document 1 is mainly applied only to large-scale buildings, and is not often applied to buildings of medium or smaller scales.

また、図9の構成では、複数階床にわたり昇降支柱体58でガイドレール56を支持しているが、地震発生時におけるガイドレール56の変形に追従するように昇降支柱体58も変形するようにしなければならない。しかし、このような変形を可能にするための剛性の確保が難しく、昇降支柱体58及びその他の構成部材の取付構造が複雑になるという問題を有していた。   In the configuration of FIG. 9, the guide rail 56 is supported by the lifting column body 58 over a plurality of floors, but the lifting column body 58 is also deformed so as to follow the deformation of the guide rail 56 when an earthquake occurs. There must be. However, it is difficult to ensure rigidity for enabling such deformation, and there is a problem in that the mounting structure of the lifting column body 58 and other components is complicated.

本発明は上記事情に鑑みてなされたものであり、建物内における有効利用可能な床面積が削減されることを極力抑制し、また、構成部材の取付構造の複雑化を回避することが可能な免震建物用エレベータの乗場ドア設置構造を提供することを目的としている。   This invention is made | formed in view of the said situation, and it can suppress that the floor area which can be used effectively in a building is reduced as much as possible, and can avoid complication of the attachment structure of a component. The purpose is to provide a landing door installation structure for elevators for base-isolated buildings.

図1は、本発明の第1の実施形態に係る乗場ドア設置構造を示す昇降路回りの縦断面図である。免震装置1は、ある特定の階床(N階)に設置されており、地震発生時にはN階とN+1階との間の相対変位を許容するようになっている。そして、建物内には昇降路2が形成され、この昇降路2内にはかご用ガイドレール3及びカウンタウェイト用ガイドレール4がレール支持部材5により配設されている。かご6及びカウンタウェイト7は、これらのガイドレール3,4に沿って互いに反対方向に昇降動するようになっている。なお、地震発生時には、免震装置1の働きによりN階とN+1階(上方隣接階)との間に相対変位が生じるので、N階における昇降路2を形成している内壁8の位置は寸法Lだけ外側にずれて大きな昇降路面積が確保されている。   FIG. 1 is a longitudinal sectional view around a hoistway showing a landing door installation structure according to a first embodiment of the present invention. The seismic isolation device 1 is installed on a specific floor (N floor), and allows relative displacement between the N floor and the N + 1 floor when an earthquake occurs. A hoistway 2 is formed in the building, and a car guide rail 3 and a counterweight guide rail 4 are disposed in the hoistway 2 by rail support members 5. The car 6 and the counterweight 7 are moved up and down in the opposite directions along the guide rails 3 and 4. In the event of an earthquake, the seismic isolation device 1 causes relative displacement between the Nth floor and the N + 1th floor (upper adjacent floor), so the position of the inner wall 8 forming the hoistway 2 on the Nth floor is a dimension. A large hoistway area is secured by shifting outward by L.

各階床の乗降口には乗場ドア9が設置されているが、これらのうち免震層階であるN階に設置されている乗場ドア9は、その周囲が乗場ドア囲み部材10により覆われている。天井から下方に延びる壁部11、及び床部12には、それぞれ溝部11a,12aが形成されている。そして、これら溝部11a,12aに、乗場ドア囲み部材10の上端部及び下端部が嵌合しており、乗場ドア囲み部材10は乗降口の乗降方向に水平移動可能になっている。   A landing door 9 is installed at the entrance / exit of each floor. Among these, the landing door 9 installed on the Nth floor, which is a seismic isolation floor, is covered with a landing door surrounding member 10. Yes. Groove portions 11a and 12a are formed in the wall portion 11 and the floor portion 12 extending downward from the ceiling, respectively. And the upper end part and lower end part of the landing door surrounding member 10 are fitted to these groove parts 11a and 12a, and the landing door surrounding member 10 is horizontally movable in the boarding / alighting direction of the entrance / exit.

昇降路2側に面した壁部11の壁面には一対の取付座13が設置されており、この一対の取付座13を1本の上部軸支部材15が挿通している。この上部軸支部材15は、乗降口の間口方向に延びる長寸状部材である。また、昇降路2側に面した床部12に続く壁面には一対の取付座14が設置されており、それぞれの取付座14を短寸状部材である下部軸支部材16が挿通している。そして、これら軸支部材15,16に、一対の乗場ドア支持部材17の上端部及び下端部が軸支されている。   A pair of mounting seats 13 are installed on the wall surface of the wall portion 11 facing the hoistway 2 side, and one upper shaft support member 15 is inserted through the pair of mounting seats 13. The upper shaft support member 15 is a long member extending in the entrance direction of the entrance. In addition, a pair of mounting seats 14 are installed on the wall surface following the floor portion 12 facing the hoistway 2 side, and a lower shaft support member 16 that is a short member is inserted through each mounting seat 14. . And the upper end part and lower end part of a pair of landing door support member 17 are pivotally supported by these pivotal support members 15 and 16.

図2は、図1における乗場ドア支持部材17回りの取付構造を示す斜視図である。この図に示すように、一対の乗場ドア支持部材17は、乗場ドア囲み部材10に周囲が覆われている乗場ドア9の両サイドに配置されており、その各上端部は、乗降口の間口方向に延びる長寸状部材である1本の上部軸支部材15により一対の取付座13に軸支されている。また、一対の乗場ドア支持部材17の各下端部は、短寸状部材である2本の下部軸支部材16により一対の取付座14に軸支されている。なお、本明細書において、乗降口の「間口方向」とは矢印Y1に示す方向であり、乗降口の「乗降方向」とは矢印Y2に示す方向である。   FIG. 2 is a perspective view showing a mounting structure around the landing door support member 17 in FIG. As shown in this figure, the pair of landing door support members 17 are disposed on both sides of the landing door 9 whose periphery is covered by the landing door surrounding member 10, and each upper end portion thereof is a frontage entrance gate A pair of mounting seats 13 are pivotally supported by one upper pivotal support member 15 that is a long member extending in the direction. The lower ends of the pair of landing door support members 17 are pivotally supported on the pair of mounting seats 14 by the two lower pivotal support members 16 that are short members. In this specification, the “entrance direction” of the entrance / exit is the direction indicated by the arrow Y1, and the “entrance / exit direction” of the entrance / exit is the direction indicated by the arrow Y2.

乗場ドア支持部材17には、乗降方向に長い形状に形成された長孔部17a,17bが設けられている。一方、乗場ドア9の側面部には、係着ロッド18,19が固着されている。これら係着ロッド18,19の先端部は乗場ドア囲み部材10を突き抜けて長孔部17a,17bを挿通した状態になっている。   The landing door support member 17 is provided with long holes 17a and 17b formed in a shape that is long in the boarding / alighting direction. On the other hand, engaging rods 18 and 19 are fixed to the side surface of the landing door 9. The front ends of the engaging rods 18 and 19 are in a state of passing through the landing door surrounding member 10 and passing through the long holes 17a and 17b.

また、長孔部17a,17bの間には、切り欠き部17cが形成されており、この切り欠き部17cに取付座20が固着されている。一方、乗場ドア9の側面部には取付座21が固着され、この取付座21は乗場ドア囲み部材10を突き抜けて取付座20と対向した状態となっている。そして、これら取付座20,21間にバネ部材22(例えばコイルバネ)が介挿されている。このバネ部材22は、圧縮された状態で介挿されており、取付座20,21間には常時一定以上の反発力が作用するようになっている。   Further, a notch 17c is formed between the long hole portions 17a and 17b, and the mounting seat 20 is fixed to the notch 17c. On the other hand, a mounting seat 21 is fixed to the side surface of the landing door 9, and the mounting seat 21 penetrates the landing door surrounding member 10 and faces the mounting seat 20. A spring member 22 (for example, a coil spring) is interposed between the mounting seats 20 and 21. The spring member 22 is inserted in a compressed state, and a repulsive force of a certain level or more is always applied between the mounting seats 20 and 21.

図3は、上記のバネ部材22が介挿された状態を示す断面図である。取付座21には、心棒23の基端部が溶着されており、この心棒23がバネ部材22の内部を挿通した状態になっている。そして、心棒23の先端部は、取付座20に形成されている孔部20aを通過して反対側に突出している。   FIG. 3 is a cross-sectional view showing a state where the spring member 22 is inserted. A base end portion of a mandrel 23 is welded to the mounting seat 21, and the mandrel 23 is inserted through the spring member 22. And the front-end | tip part of the mandrel 23 passes the hole 20a formed in the attachment seat 20, and protrudes on the opposite side.

次に、上記のように構成される第1の実施形態の作用につき説明する。通常時すなわち地震が発生していない時には、N階とN+1階との間の相対変位量は殆どなく、したがって図1に示されるように、ガイドレール3,4も変形することなく昇降路2内を直線状に上下に延びた状態になっている。   Next, the operation of the first embodiment configured as described above will be described. In normal times, that is, when there is no earthquake, there is almost no relative displacement between the Nth floor and the N + 1th floor, and therefore the guide rails 3 and 4 are not deformed in the hoistway 2 as shown in FIG. Is in a state of extending vertically up and down.

しかし、地震が発生すると、免震装置1の働きによりN階とN+1階との間の相対変位量が大きくなり、ガイドレール3,4も通常時の位置から大きく水平方向に変位して変形する。図4は、N階に対してN+1階が左方に変位した状態を示し、図5は、N階に対してN+1階が右方に変位した状態を示している。   However, when an earthquake occurs, the amount of relative displacement between the Nth floor and the (N + 1) th floor is increased by the function of the seismic isolation device 1, and the guide rails 3 and 4 are also largely displaced from the normal position in the horizontal direction and deformed. . FIG. 4 shows a state in which the N + 1 floor is displaced to the left with respect to the N floor, and FIG. 5 shows a state in which the N + 1 floor is displaced to the right with respect to the N floor.

ここで、ガイドレール3,4を支持する支持部材は、昇降路2区間中のN階(免震層階)を通る区間には配設されておらず、この区間ではガイドレール3,4はN階とN+1階との間の相対変位に容易に追従して変形できるようになっている。つまり、図4又は図5において、レール支持部材5,5Aの取付位置はN階に対してそれぞれ下方及び上方になっており、レール支持部材5,5A間の距離が長くなっているため、必要な強度を維持しつつ変形が可能になっている。これに対し、N階とN−1階との間の相対変位は、N階とN+1階との間ほどには大きくならないため、レール支持部材5,5B間の距離はそれほど長くする必要はない。   Here, the supporting members for supporting the guide rails 3 and 4 are not arranged in the section passing through the N floor (the seismic isolation layer floor) in the section of the hoistway 2, and the guide rails 3 and 4 are not disposed in this section. It can be easily deformed by following the relative displacement between the Nth floor and the N + 1th floor. That is, in FIG. 4 or FIG. 5, the mounting positions of the rail support members 5 and 5A are respectively downward and upward with respect to the N floor, and the distance between the rail support members 5 and 5A is long. Deformation is possible while maintaining high strength. On the other hand, the relative displacement between the Nth floor and the (N−1) th floor is not as great as that between the Nth floor and the (N + 1) th floor, so the distance between the rail support members 5 and 5B does not need to be so long. .

図4に示した状態では、N+1階の左方への相対変位に伴って、乗場ドア支持部材17が左方へ傾斜し、またガイドレール3及びかご6も左方に傾斜した状態になっている。しかし、溝部11a,12aに上端部及び下端部が嵌合している乗場ドア囲み部材10は乗降口の乗降方向に水平移動可能であるため、乗場ドア囲み部材10及びその内部に配設されている乗場ドア9は垂直姿勢を維持している。   In the state shown in FIG. 4, with the relative displacement to the left of the N + 1 floor, the landing door support member 17 is inclined to the left, and the guide rail 3 and the car 6 are also inclined to the left. Yes. However, since the landing door surrounding member 10 whose upper end and lower end are fitted in the grooves 11a and 12a can move horizontally in the direction of getting on and off the entrance, it is disposed in the landing door surrounding member 10 and inside thereof. The landing door 9 is maintained in a vertical posture.

したがって、乗場ドア9上部側ではかご6上部側との距離が小さくなって接近した状態となり、一方、乗場ドア9下部側ではかご6下部側との距離が大きくなって離間した状態となる。しかし、下部軸支部材16と長孔部17aとの間の距離は、下部軸支部材16と上部軸支部材15との間の距離の約4分の3となっているため、乗場ドア9及び乗場ドア囲み部材10の移動量も、N階とN+1階との間の相対変位量の約4分の3となる。そのため、乗場ドア9上部側とかご6上部側とが接触することはなく、かご6はN階を通過することが可能である。   Accordingly, the distance from the upper side of the car 6 is reduced and approached on the upper side of the landing door 9, while the distance from the lower side of the car 6 is increased and separated from the lower side of the landing door 9. However, since the distance between the lower shaft support member 16 and the long hole portion 17a is about three-fourths of the distance between the lower shaft support member 16 and the upper shaft support member 15, the landing door 9 The moving amount of the landing door surrounding member 10 is also about three quarters of the relative displacement amount between the Nth floor and the N + 1th floor. Therefore, the upper side of the landing door 9 and the upper side of the car 6 do not contact each other, and the car 6 can pass through the Nth floor.

一方、図5に示した状態では、N+1階の右方への相対変位に伴って、乗場ドア支持部材17が右方へ傾斜し、またガイドレール3及びかご6も右方に傾斜した状態になっている。しかし、溝部11a,12aに上端部及び下端部が嵌合している乗場ドア囲み部材10は乗降口の乗降方向に水平移動可能であるため、乗場ドア囲み部材10及びその内部に配設されている乗場ドア9は垂直姿勢を維持している。   On the other hand, in the state shown in FIG. 5, the landing door support member 17 is inclined to the right with the relative displacement of the N + 1 floor to the right, and the guide rail 3 and the car 6 are also inclined to the right. It has become. However, since the landing door surrounding member 10 whose upper end and lower end are fitted in the grooves 11a and 12a can move horizontally in the direction of getting on and off the entrance, it is disposed in the landing door surrounding member 10 and inside thereof. The landing door 9 is maintained in a vertical posture.

したがって、乗場ドア9下部側ではかご6下部側との距離が小さくなって接近した状態となり、一方、乗場ドア9上部側ではかご6上部側との距離が大きくなって離間した状態となる。しかし、下部軸支部材16と長孔部17bとの間の距離は、下部軸支部材16と上部軸支部材15との間の距離の約4分の1となっているため、乗場ドア9及び乗場ドア囲み部材10の移動量も、N階とN+1階との間の相対変位量の約4分の1となる。そのため、乗場ドア9上部側とかご6上部側とが接触することはなく、かご6はN階を通過することが可能である。   Accordingly, the distance from the lower side of the car 6 is reduced and approached on the lower side of the landing door 9, while the distance from the upper side of the car 6 is increased and separated from the upper side of the landing door 9. However, since the distance between the lower shaft support member 16 and the long hole portion 17b is about a quarter of the distance between the lower shaft support member 16 and the upper shaft support member 15, the landing door 9 The moving amount of the landing door surrounding member 10 is also about one-fourth of the relative displacement amount between the Nth floor and the N + 1th floor. Therefore, the upper side of the landing door 9 and the upper side of the car 6 do not contact each other, and the car 6 can pass through the Nth floor.

また、図5の状態では、N+1階の右方への相対変位に伴って、乗場ドア9が昇降路2側にせり出した状態となっているが、乗場ドア9の周囲は乗場ドア囲み部材10で覆われており、この乗場ドア囲み部材10の幅は乗場ドア9の幅よりも充分に大きなものとなっている。したがって、乗場ドア9の前に立っている利用者が、床部12の縁部と乗場ドア9との間に生じた下方の隙間から足を踏み外したり、また、上方又は側方の隙間からの落下物にぶつかるなどの事故を防止することができる。   Further, in the state of FIG. 5, the landing door 9 protrudes to the hoistway 2 side with the relative displacement of the N + 1 floor to the right, but the periphery of the landing door 9 is the landing door surrounding member 10. The width of the landing door surrounding member 10 is sufficiently larger than the width of the landing door 9. Therefore, a user standing in front of the landing door 9 may step out of the lower gap formed between the edge of the floor 12 and the landing door 9, or may be removed from the upper or side gap. Accidents such as hitting falling objects can be prevented.

図4及び図5は、N階とN+1階との間の相対変位が乗降口の乗降方向である場合の状態を示したものであるが、地震発生の際の実際の相対変位は、乗降方向ばかりでなく間口方向についても同時に発生する。図6は、図5のVI-VI方向矢視図であり、乗降口の間口方向におけるN階とN+1階との間の相対的水平変位の状態を示した説明図である。この図に示すように、N+1階がN階に対してδだけ右方に水平変位したので(あるいはN階がN+1階に対してδだけ左方に水平変位したので)、左側乗場ドア支持部材17と左側取付座13との間の隙間はゼロであるが、右側乗場ドア支持部材17と右側取付座13との間の隙間gは大きくなっている。つまり、乗場ドア支持部材17は、N階とN+1階との間に間口方向へのズレが生じても、長寸状部材である上部軸支部材15に沿って乗降口の間口方向に水平変位を行うことができるので、変形又は破損を生じることがない。この場合、乗場ドア9は乗降口の間口方向に変位するため、かご6に対する乗降範囲の幅がある程度狭められることにはなるが、利用者の乗降に支障が生じるほどのものではなく実用上問題になることはない。   4 and 5 show the state where the relative displacement between the Nth floor and the (N + 1) th floor is the boarding / alighting direction of the entrance / exit, but the actual relative displacement at the time of the earthquake occurrence is the boarding / alighting direction. Not only does it occur in the frontage direction at the same time. FIG. 6 is a view taken in the direction of the arrow VI-VI in FIG. 5 and is an explanatory diagram showing a state of relative horizontal displacement between the N floor and the N + 1 floor in the entrance direction of the entrance. As shown in this figure, since the N + 1 floor is horizontally displaced to the right by δ with respect to the N floor (or the N floor is horizontally displaced to the left by δ with respect to the N + 1 floor), the left landing door support member The gap between the left mounting seat 13 and the left mounting seat 13 is zero, but the gap g between the right landing door support member 17 and the right mounting seat 13 is large. That is, the landing door support member 17 is horizontally displaced in the entrance direction of the entrance along the upper shaft support member 15 which is a long member, even if there is a deviation in the entrance direction between the Nth floor and the (N + 1) th floor. Therefore, deformation or breakage does not occur. In this case, since the landing door 9 is displaced in the entrance direction of the entrance / exit, the width of the entrance / exit range for the car 6 will be reduced to some extent, but this is not a problem that causes a problem in getting on / off the user and is a practical problem. Never become.

なお、本実施形態では、一対の乗場ドア支持部材17の上端部を1本の長寸状上部軸支部材15で軸支し、下端部を2本の短寸状下部軸支部材16で軸支する構成を採用しているが、これを逆にして、一対の乗場ドア支持部材17の上端部を2本の短寸状上部軸支部材で軸支し、下端部を1本の長寸状下部軸支部材で軸支する構成を採用してもよい。   In the present embodiment, the upper ends of the pair of landing door support members 17 are pivotally supported by one long upper support member 15 and the lower ends are pivoted by two short lower support members 16. Although the structure which supports is employ | adopted, this is reversed, and the upper end part of a pair of landing door support member 17 is pivotally supported by two short-shaped upper axis | shaft support members, and a lower end part is one long dimension. You may employ | adopt the structure supported by a shape lower shaft support member.

ここで、図2において、取付座20,21間に介挿されているバネ部材22の機能につき説明する。現在、取付座20,21間にはバネ部材22の反発力が働いており、係着ロッド18,19はそれぞれ長孔部17a,17bの右側縁部に内接した状態になっている。   Here, the function of the spring member 22 inserted between the mounting seats 20 and 21 in FIG. 2 will be described. At present, the repulsive force of the spring member 22 is acting between the mounting seats 20 and 21, and the engaging rods 18 and 19 are in contact with the right edge portions of the long hole portions 17a and 17b, respectively.

この状態で地震が発生し、壁部11が乗降方向(Y2)のうちの一方の方向(例えば左方奥側)に移動すると、乗場ドア支持部材17は、下部軸支部材16を中心として、左方奥側へある角度だけ回転(傾斜)する。したがって、係着ロッド18が長孔部17aの右側縁部に規制されることにより乗場ドア9も左方奥側へ水平移動する。なお、係着ロッド19も長孔部17bに規制されているが、下部軸支部材16を中心とする円弧の長さは係着ロッド19よりも係着ロッド18の方が大きいので、乗場ドア9の水平移動量は係着ロッド19の移動量により決まる。   When an earthquake occurs in this state and the wall 11 moves in one direction (for example, the left back side) in the boarding / alighting direction (Y2), the landing door support member 17 is centered on the lower pivot support member 16. Rotate (tilt) a certain angle to the far left side. Therefore, when the engaging rod 18 is restricted to the right edge of the long hole portion 17a, the landing door 9 also moves horizontally to the left rear side. Although the engaging rod 19 is also restricted by the long hole portion 17b, the length of the arc centered on the lower shaft support member 16 is larger in the engaging rod 18 than in the engaging rod 19, so that the landing door The horizontal movement amount 9 is determined by the movement amount of the engaging rod 19.

乗場ドア9がこのような水平移動を行っている間、取付座21はバネ部材22により常時反発力を受けている。したがって、乗場ドア支持部材17の回転動作(傾斜動作)が急停止した場合に、係着ロッド18が長孔部17aの左側縁部に対して勢いよくぶつかることを防止することができる。   While the landing door 9 performs such horizontal movement, the mounting seat 21 is constantly repelled by the spring member 22. Therefore, when the rotation operation (tilting operation) of the landing door support member 17 is suddenly stopped, it is possible to prevent the engaging rod 18 from strikingly against the left edge of the long hole portion 17a.

次いで、壁部11が移動方向を反転させ、今度は乗降方向(Y2)のうちの他方の方向(右方手前側)に移動すると、係着ロッド18が長孔部17aの左側縁部に規制されることにより、乗場ドア9は右方手前側へ水平移動する。この水平移動の間も取付座21はバネ部材22により常時反発力を受けている。したがって、今度も乗場ドア支持部材17の回転動作(傾斜動作)が急停止した場合に、係着ロッド18が長孔部17aの右側縁部に対して勢いよくぶつかることを防止することができる。   Next, when the wall portion 11 reverses the moving direction and this time moves in the other direction (right front side) of the getting-on / off direction (Y2), the engaging rod 18 is restricted to the left edge portion of the long hole portion 17a. As a result, the landing door 9 moves horizontally to the right front side. During this horizontal movement, the mounting seat 21 always receives a repulsive force by the spring member 22. Therefore, when the rotation operation (tilting operation) of the landing door support member 17 is suddenly stopped again, it is possible to prevent the engaging rod 18 from striking the right edge portion of the long hole portion 17a.

このように、バネ部材22は、地震発生の際に乗場ドア支持部材17が回転(傾斜)を急停止したり回転方向(傾斜方向)を急転換させた場合のダンパとして機能している。したがって、地震発生の際の振動が急峻な場合でも、係着ロッド18,19が長孔部17a,17bの内側と激しく衝突して乗場ドア9側に大きな衝撃を与え、各種部材又は機器類に悪影響を及ぼすような事態を回避することができる。   Thus, the spring member 22 functions as a damper when the landing door support member 17 suddenly stops rotating (tilting) or suddenly changes its rotating direction (tilting direction) when an earthquake occurs. Therefore, even when the vibration at the time of earthquake occurrence is steep, the engaging rods 18 and 19 collide violently with the insides of the long hole portions 17a and 17b and give a large impact to the landing door 9 side, thereby causing various members or equipment to It is possible to avoid a situation that has an adverse effect.

なお、図2においては、長孔部17a,17bの長軸形成方向は矢印Y2方向に沿った水平方向になっており、乗場ドア囲み部材10の水平移動を可能にしている。ところが、乗場ドア支持部材17は下部軸支部材16を中心とした回転動作を行っているので、この回転動作を重視した観点からは、これら長孔部17a,17bの形状も、下部軸支部材16を中心とする円弧の一部とすべきであるともいえる。しかし、実際には乗場ドア支持部材17の回転角度はそれほど大きなものではなく、また長孔部17a,17bの幅(すなわち短軸長さ)を係着ロッド18,19の直径よりもある程度余裕を持って大きくしておけば、図2のように長軸形成方向が水平方向であっても実用上問題が生じることはない。   In FIG. 2, the long axis forming direction of the long hole portions 17a and 17b is a horizontal direction along the direction of the arrow Y2, and the landing door surrounding member 10 can be moved horizontally. However, since the landing door support member 17 rotates around the lower shaft support member 16, from the viewpoint of emphasizing this rotation operation, the shape of the elongated holes 17a, 17b is also the lower shaft support member. It can be said that it should be part of an arc centered at 16. However, in actuality, the rotation angle of the landing door support member 17 is not so large, and the width of the long hole portions 17a and 17b (that is, the short axis length) is somewhat larger than the diameter of the engaging rods 18 and 19. If it is held large, there will be no practical problem even if the long axis formation direction is the horizontal direction as shown in FIG.

このように、第1の実施形態の構成では、地震発生時に免震装置1の働きによってN階とN+1階との間に相対変位が生じても、この相対変位に追従するように、N階の乗場ドア支持部材17が回転して乗場ドア囲み部材10及び乗場ドア9が垂直姿勢を維持した状態で水平移動する。したがって、ガイドレール3とかご6との間の距離が大きく変動するのを防ぐことができ、利用者は乗場ドア9を通ってかご6に対する乗降を支障なく行うことができると共に、かご6は乗場ドア9にぶつかることなくN階を通過することができる。   As described above, in the configuration of the first embodiment, even if a relative displacement occurs between the Nth floor and the N + 1th floor due to the action of the seismic isolation device 1 when an earthquake occurs, the Nth floor The landing door support member 17 rotates and the landing door surrounding member 10 and the landing door 9 horizontally move while maintaining a vertical posture. Therefore, it is possible to prevent the distance between the guide rail 3 and the car 6 from greatly fluctuating, and the user can get on and off the car 6 through the landing door 9 without any trouble. It is possible to pass through the N floor without hitting the door 9.

そして、第1の実施形態の構成は、図9に示した従来構成のように、昇降支柱体を用いるものではないので、昇降路2の面積を大きくする必要はなく、建物内における有効利用可能な床面積が削減されることはない。   And since the structure of 1st Embodiment does not use a raising / lowering support | pillar body like the conventional structure shown in FIG. 9, it is not necessary to enlarge the area of the hoistway 2, and it can be used effectively in a building. The floor space is not reduced.

また、第1の実施形態の構成は、免震層階における乗場ドアの取付構造も複雑なものではないため、新規な建物は勿論のこと、既存の建物を免震構造とするような場合にも積極的に採用することができると共に、ビルの規模の大小を問わず採用することが可能である。   In addition, since the structure of the first embodiment is not complicated in the structure of the landing door on the seismic isolation floor, not only a new building but also an existing building having a seismic isolation structure. Can be employed actively, and can be employed regardless of the size of the building.

更に、第1の実施形態の構成は、乗場ドア9側とガイドレール3側との間が機械的に連結された構造となっているわけではなく、切り離された構造となっているので、乗場ドア9側とガイドレール3側との間に垂直方向の大きな相対変位が生じたとしても、これにより乗場ドア9付近の部材に大きな力が加わり、破損するような事態を回避することができる。   Furthermore, the configuration of the first embodiment is not a structure in which the landing door 9 side and the guide rail 3 side are mechanically coupled, but a separated structure. Even if a large relative displacement in the vertical direction occurs between the door 9 side and the guide rail 3 side, it is possible to avoid a situation in which a large force is applied to the members near the landing door 9 to cause damage.

図7は、本発明の第2の実施形態に係る乗場ドア設置構造を示す昇降路回りの縦断面図である。免震層階であるN階と、その上方隣接階であるN+1階との間の相対変位には、建物の規模や免震層階の設置位置によっては、水平面内での回転成分が含まれるような場合も生じるが、この実施形態はこのような場合に有効に機能する。   FIG. 7 is a longitudinal sectional view around a hoistway showing a landing door installation structure according to the second embodiment of the present invention. The relative displacement between the Nth floor, which is the seismic isolation layer, and the N + 1 floor, which is the upper adjacent floor, includes a rotational component in the horizontal plane depending on the size of the building and the installation position of the seismic isolation layer Although this may occur, this embodiment functions effectively in such a case.

図7が図1と異なる点は、取付座13の代わりにユニバーサルジョイント部材24が壁部11に設置されており、乗場ドア支持部材17の上端部は上部軸支部材15を介してこのユニバーサルジョイント部材24に取り付けられている点である。   7 differs from FIG. 1 in that a universal joint member 24 is installed on the wall portion 11 instead of the mounting seat 13, and the upper end portion of the landing door support member 17 is connected to the universal joint via the upper shaft support member 15. It is attached to the member 24.

図8は、図7における乗場ドア支持部材17回りの取付構造を示す斜視図である。この図に示すように、ユニバーサルジョイント部材24は、長寸状部材である上部軸支部材15の中間部に取り付けられている。したがって、乗場ドア9は、地震発生時に、矢印Y3で示すような水平面内での回転、あるいは矢印Y1に示すような間口方向への水平変位が許容される。   FIG. 8 is a perspective view showing a mounting structure around the landing door support member 17 in FIG. As shown in this figure, the universal joint member 24 is attached to an intermediate portion of the upper shaft support member 15 which is a long member. Accordingly, the landing door 9 is allowed to rotate in a horizontal plane as indicated by the arrow Y3 or to be horizontally displaced in the frontage direction as indicated by the arrow Y1 when an earthquake occurs.

図9は、図7のIX-IX方向矢視図であり、乗降口の間口方向におけるN階とN+1階との間の相対的水平変位の状態を示した説明図である。この図に示すように、N+1階がN階に対してδだけ右方に水平変位したので(あるいはN階がN+1階に対してδだけ左方に水平変位したので)、ユニバーサルジョイント部材24は上部軸支部材15の中央部よりやや右方にずれている。   FIG. 9 is an IX-IX direction arrow view of FIG. 7 and is an explanatory diagram showing a state of relative horizontal displacement between the Nth floor and the (N + 1) th floor in the entrance direction of the entrance. As shown in this figure, since the N + 1 floor is horizontally displaced to the right by δ with respect to the N floor (or the N floor is horizontally displaced to the left by δ with respect to the N + 1 floor), the universal joint member 24 is The upper shaft support member 15 is shifted slightly to the right from the central portion.

なお、乗場ドア9の回転又は水平変位が許容されるといっても、これらの回転又は水平変位は乗場ドア9上方の壁部11に対して相対的なものである。つまり、図8において、実際には乗場ドア9上方の壁部11が矢印Y3で示すように水平面内で回転したり、あるいは矢印Y1に示すように間口方向に水平変位したりしても、乗場ドア9はこれらの回転又は水平変位に影響されることなく、そのままの静止状態を維持することができると表現した方が理解しやすい。   Even if rotation or horizontal displacement of the landing door 9 is allowed, these rotation or horizontal displacement is relative to the wall portion 11 above the landing door 9. That is, in FIG. 8, even if the wall portion 11 above the landing door 9 actually rotates in the horizontal plane as indicated by the arrow Y3 or is horizontally displaced in the frontage direction as indicated by the arrow Y1, It is easier to understand that the door 9 can be maintained as it is without being affected by these rotations or horizontal displacements.

次に、このように構成される第2の実施形態の作用につき説明する。地震が発生し、乗場ドア9上方の壁部11が矢印Y2の乗降方向に変位すると、これに応じて一対の乗場ドア支持部材17が下部軸支部材16を中心として左方奥側又は右方手前側に回転(傾斜)し、したがって乗場ドア9及び乗場ドア囲み部材10が左方奥側又は右方手前側に水平移動する。このときの詳しい動作は第1の実施形態で既述した通りである。   Next, the operation of the second embodiment configured as described above will be described. When an earthquake occurs and the wall 11 above the landing door 9 is displaced in the direction of getting in and out of the arrow Y2, the pair of landing door support members 17 correspondingly move the left rear side or the right side with the lower pivot support member 16 as the center. Accordingly, the landing door 9 and the landing door surrounding member 10 are horizontally moved to the left rear side or the right front side. The detailed operation at this time is as described in the first embodiment.

そして、乗場ドア9上方の壁部11は、矢印Y2の乗降方向に水平変位すると同時に、水平面内で矢印Y3方向に回転(又は捩れ)を生じる場合がある。このような場合、この壁部11の回転に追従してユニバーサルジョイント部材24も上部軸支部材15に対して矢印Y3方向に回転する。したがって、壁部11の回転による影響は上部軸支部材15に伝達されることはなく、一対の乗場ドア支持部材17の上端部に捩れが生じることが回避される。   The wall 11 above the landing door 9 may be horizontally displaced in the direction of getting in and out of the arrow Y2, and at the same time rotate (or twist) in the direction of the arrow Y3 in the horizontal plane. In such a case, following the rotation of the wall 11, the universal joint member 24 also rotates in the direction of the arrow Y 3 with respect to the upper shaft support member 15. Therefore, the influence of the rotation of the wall portion 11 is not transmitted to the upper shaft support member 15, and it is avoided that the upper end portions of the pair of landing door support members 17 are twisted.

また、乗場ドア9上方の壁部11が矢印Y1の間口方向に変位すると、ユニバーサルジョイント部材24もこれに追従して上部軸支部材15上をスライドする。例えば、壁部11が左方手前側に変位すると、ユニバーサルジョイント部材24も上部軸支部材15に沿って左方手前側に移動する。したがって、一対の乗場ドア支持部材17、乗場ドア9及び乗場ドア囲み部材10は、壁部11の矢印Y1の間口方向への変位の影響を受けることがない。   When the wall 11 above the landing door 9 is displaced in the direction of the front edge of the arrow Y1, the universal joint member 24 follows this and slides on the upper shaft support member 15. For example, when the wall portion 11 is displaced to the left front side, the universal joint member 24 also moves to the left front side along the upper shaft support member 15. Therefore, the pair of landing door support members 17, the landing door 9, and the landing door surrounding member 10 are not affected by the displacement of the wall portion 11 in the direction of the gap Y1.

なお、本実施形態では、一対の乗場ドア支持部材17の上端部側にユニバーサルジョイント部材24を取り付ける構成を採用しているが、このユニバーサルジョイント部材24を一対の乗場ドア支持部材17の下端部側に取り付ける構成としてもよい。   In addition, in this embodiment, although the structure which attaches the universal joint member 24 to the upper end part side of a pair of landing door support member 17 is employ | adopted, this universal joint member 24 is the lower end part side of a pair of landing door support member 17 It is good also as a structure attached to.
