【発明の属する技術分野】
本発明は免震建物のエレベータ昇降路に関し、とりわけ地震時において免震装置を介在する建物の上層と下層の相対変位にエレベータ昇降路を追従させることにより、エレベータの昇降不能状態を回避できるようにしたものである。
【0002】
【従来の技術】
免震建物は免震装置を建物の下層と上層との間に介在させた建物であるから、地震時には上層と下層間に相対変位が生じることが明らかで、そのために、下層と上層とで連通するエレベータ昇降路を設けると、下層と上層間でエレベータ昇降路が遮断される事態が生じるので、エレベータが昇降移動できなくなる恐れがある。そのため、このような事態が生じるのを避けるべく、多くの免震建物では免震装置を挟む下層と上層とでエレベータをそれぞれ別途に設けて最上層へ行く場合には乗り換えるようにしている。
【0003】
しかし、乗り換える面倒を省くために、下層と上層とで連通するエレベータ昇降路を設け、免震装置を介在した下層と上層間の相対変位にエレベータかごのガイドレールを追従可能に構成することによってエレベータ昇降路の遮断を生じさせないようにした提案がなされている(特開平9−278315号、特開平10−231075号及び特開平11−29277号公報参照)。
【0004】
【発明が解決しようとする課題】
しかしながら、特開平9−278315号公報記載の発明では、免震装置を有する中間層に、上下端部に球座ジョイントを備えたレール支持材を揺動自在に支持し、このレール支持材に中間レールを支持固定し、その中間レールの上下端部を同じく球座ジョイント又は変形可能な接続レールで上層レール及び下層レールと揺動自在に連結しているので、構造簡素ではあるが、信頼性と安全性に乏しい面がある。
【0005】
また、特開平10−231076号公報記載の発明では、免震装置を介在する高層部建物と低層部建物とに跨って支柱体支持梁を設け、この支柱支持梁で昇降支持体を支持し、その昇降支持体にガイドレールを支持しているので、構造頑健な様子で信頼性と安全性は向上することが見込まれるが、施工コストが高くて経済性の点で難点がある。
【0006】
さらに、特開平11−29277号公報記載の発明では、免震階を含む複数の階層にわたって、ガイドレールとは別にガイドレールの両側に補強支柱を平行に設置し、補強支柱の上下端部は上層と下層にそれぞれ前後左右へ揺動可能に支持し、補強支柱間に横梁を連結して略平行四辺形の枠体を形成し、その横梁にガイドレールをスライド自在に取り付けているので、層間の相対変位に対し枠体が平行リンク状態で変形することによりガイドレールの弾性変形を促すようにしたものであるが、補強支柱の上下端部を上層と下層にそれぞれ前後左右へ揺動可能に支持する構造は複雑で施工工事に手間を要するため、施工コストが上昇する難点がある。
【0007】
そこで、本発明は施工コストを低く抑えることができて、しかも信頼性と安全性の高い免震建物のエレベータ昇降路を提供する。
【0008】
【課題を解決するための手段】
上記課題を達成すべく、請求項1の発明は、免震装置を介在した建物の下層と上層間を連通するエレベータ昇降路において、前記エレベータ昇降路内に矩形の剛性枠体をその上端部を上層に、下端部を下層にそれぞれ弾機を介して揺動可能に支持せしめ、かつ、その剛性枠体にエレベータかごのガイドレールを係止せしめた免震建物のエレベータ昇降路において、
前記剛性枠体の上辺とその上部支持部材との間の略中央部及び剛性枠体の下辺とその下部支持部材との間の略中央部に連結してそれぞれ遊動可能に係合するストッパーを設けた
【0009】
請求項2の発明は、免震装置を介在した建物の下層と上層間を連通するエレベータ昇降路において、前記エレベータ昇降路内に矩形の剛性枠体をその上端部を上層に、下端部を下層にそれぞれ弾機を介して揺動可能に支持せしめ、かつ、その剛性枠体にエレベータかごのガイドレールを係止せしめた免震建物のエレベータ昇降路において、四個の剛性枠体を立方形状に連結して一体の剛性筺枠を形成し、この剛性筺枠を下層と上層間の昇降路内に弾機を介して揺動可能に介在させ、その剛性筺枠内にエレベータかごのガイドレールをアブソーバを介して係止せしめた。
【0011】
かくして、免震装置を介在する下層と上層間のエレベータ昇降路に剛性枠体若しくは剛性筺枠を弾機を介して配設したので、地震時に層間の相対変位が生じても弾機でその変位が吸収されることにより、剛性枠体若しくは剛性筺枠が変形することなくガイドレールを保持した状態で揺動するので、エレベータの昇降を妨げるようなガイドレールの変形・破壊を防止する。
【0012】
【発明の実施の形態】
以下、本発明の実施の形態を図に基づき説明する。
【0013】
前記目的のために構成した実施の第1形態を説明すると、図1及び図2に示すように、免震装置1を介在する下層2と上層3間に、矩形の剛性枠体4を揺動可能に固定し、この剛性枠体4にガイドレール5を支持する。ガイドレール5はエレベータかごの昇降案内をするもので、昇降路内に相対する対で設けられる。
【0014】
剛性枠体4は平行四辺形の縦長枠体からなり、その内部に上下配置で少なくとも2本の横梁6を有して、好ましくは斜めの複数のトラス材を組み込むことにより、それ自体としては剛性を有して平行四辺形が容易に変形しないように構成されている。
【0015】
この剛性枠体4の上辺4aと下辺4bにそれぞれ、両端部にねじ部を有する長尺ボルトからなる少なくとも2本の吊支棒8,8を遊嵌して貫通させる。この吊支棒8は上下それぞれ2本として図示したが、3本でも4本でもよく、またその配置は一直線上同列としたがそれに限定するものではない。
【0016】
上辺4a側では、吊支棒8の上端部側は上層3に固定した上部支持部材9とそれに載置する台座10を遊嵌して貫通させ、コイルスプリングなどの弾機11を挿通し、その弾機11に当接するワッシャー12を介在してナット13で締結する一方、その下端部側は剛性枠体4の内辺側にワッシャー12を挿通してナット13で締結する。
【0017】
下辺4b側では、吊支棒8の上端部側は剛性枠体4の内辺側にワッシャー17を挿通してナット18で締結する一方、下端部側は下層2に固定した下部支持部材14とそれに載置する台座15を遊嵌して貫通させ、コイルスプリングなどの弾機16を挿通し、その弾機16に当接するワッシャー17を介在してナット18で締結してある。
【0018】
上部支持部材9及び下部支持部材14はアングル材とそれに溶接した板体からなりエレベータ昇降路内に張り出して設けられる。台座10,15は上部支持部材9及び下部支持部材14に固定又は水平方向へ摺動可能に載置されている。この台座10,15に吊支棒8,8が軸方向へ移動可能に貫通しているので、吊支棒8,8は上下動可能である。
【0019】
また剛性枠体4の上辺4aと下辺4bの略中央部にはそれぞれ、ストッパー20,20が設けられる。このストッパー20は、図2中の円内に示すように、台座10,15に固定した外筒体21に、上部支持部材11及び下部支持部材14にそれぞれ固定したピストンロッド22を軸方向に嵌合して係合させたもので、ピストンロッド22の先端には外筒体21内を軸方向に移動可能なヘッド23が設けられて空圧シリンダが形成されている。
【0020】
したがって、剛性枠体4はそれ自体が変形することなく、上層3と下層2の相対変位に対しては揺動できる。また、剛性枠体4の過大な動きに対してはストッパー20,20で規制することができる。
【0021】
この剛性枠体4の横梁6に、下層2から上層3に至るガイドレール5が一対の挟持部材30,30でスライド自在に固定される。挟持部材30はオフセットした両端部を有する細長の板金からなり、その一端部側が横梁6に溶接にて固定され、他端部側は断面T字形のガイドレール5の鉄床部の片側を押さえるように、しかし、ガイドレール5が上下方向と左右方向へ移動可能に規制している。
【0022】
したがって、下層2と上層3間に相対変位が生じたときは、図3に示すように、例えば、免震装置1が右方へ傾いて、下部取付部材14に対し上部取付部材9が右方へ移動すると、吊支棒8,8が軸方向へ移動することにより、上下の吊支棒8,8に係合する弾機11,16が圧縮と伸長をしてその移動を許容する。また、図4に示すように、例えば、免震装置1が後方へ傾いて、下部取付部材14に対し上部取付部材9が後方へ移動すると、吊支棒8,8が軸方向へ移動することにより、上下の吊支棒8,8に係合する弾機11,16が圧縮と伸長をしてその移動を許容する。
【0023】
そこで、剛性枠体4は変形することなくしてガイドレール5が破壊されることもなく、層間の相対変位に追従することができる。しかも、剛性枠体4の過大な動きに対し、ストッパー20,20がそれを規制するように作用することで防止する。
【0024】
次に、本発明の実施の第2形態を説明すると、図5に示すように、免震装置1を介在する下層2と上層3間に、剛性筺枠40を弾機42を介して揺動可能に固定し、この剛性筺枠40に下層2と上層3に設けたガイドレール5,5と接続するガイドレール50を、図8に示すようなアブソーバ41を介して揺動可能に支持する。
【0025】
剛性筺枠40は前述したような剛性枠体4の4枚を立方形状に組み合わせて剛体としたもので、その上下端部の各角部にはコイルスプリングなどの弾機42をX,Y,Zの3次元方向に少なくとも3個配置し、それらの弾機42を下層2と上層3に形成した剛性筺枠収納部43,44の内側側面と内側上面、又は、内側側面と内側下面に当接させることによって剛性筺枠収納部43内に揺動可能に浮かせた状態で固定する。
【0026】
この剛性筺枠40内でガイドレール50を支持するアブソーバ41は、例えば、剛性筺枠40の内壁に固定した台座45の両端部側に軸支されたアイボルト状の支持棒46と、ガイドレール50を固定するブラケット49に軸支されたアイボルト状の支持棒47とがシリンダー48の両端部に係合し、シリンダー48内で支持棒46,47にスプリングを連結して伸縮可能に構成されたものである。
【0027】
このアブソーバ41の4本をブラケット49に連結して八の字状に上下方向へ拡げて台座45,45に連結して固定する(図8(a)参照)。したがって、ガイドレール50が剛性筺枠40側に押された場合には、図8(b)のように剛性筺枠40側へ座屈してガイドレール50の変位を許容することで、その破壊を防止する。
【0028】
したがって、下層2と上層3間に相対変位が生じたときは、図7に示すように、層間の変位に対応して剛性筺枠40が揺動し、その動きは弾機42の圧縮と伸長にて吸収して許容される。この場合に、ガイドレール50が破壊されないように、上下のガイドレール5との接続部51,51にボールジョイントを用いたり若しくは変形可能な適宜の接続ジョイントで連結しておく。
【0029】
かくして、免震建物における層間の相対変位に剛性枠体4、若しくは、その発展形態である剛性筺枠40を揺動可能に配設することでエレベータかご52のガイドレール5,50の破壊を防止するようにしたから、地震時における免震建物のエレベータ昇降路の昇降不能状態が生じることなく、スムーズな運転が可能になるから、安全性が向上する。
【0030】
【発明の効果】
以上説明したこの発明によれば、剛性枠体若しくは剛性筺枠を弾機を介して免震装置を介在する下層と上層間のエレベータ昇降路に配置するものであるから、施工コストを低く抑えることができ、しかも、剛体でガイドレールを支持するから信頼性と安全性の高い免震建物のエレベータ昇降路を得ることができる。

BACKGROUND OF THE INVENTION
The present invention relates to an elevator hoistway of a seismic isolation building, and in particular, by making the elevator hoistway follow the relative displacement of the upper and lower layers of the building that interposes the seismic isolation device at the time of an earthquake, so that the elevator can not be lifted is avoided. It is a thing.
[0002]
[Prior art]
Since a base-isolated building is a building with a base isolation device interposed between the lower and upper layers of the building, it is clear that relative displacement occurs between the upper and lower layers during an earthquake. If the elevator hoistway is provided, the elevator hoistway is interrupted between the lower layer and the upper layer, so that the elevator may not be able to move up and down. Therefore, in order to avoid the occurrence of such a situation, in many seismic isolation buildings, elevators are separately provided in the lower layer and the upper layer sandwiching the seismic isolation device, and are switched when going to the uppermost layer.
[0003]
However, to eliminate the hassle of changing trains, an elevator hoistway that communicates between the lower layer and the upper layer is provided, and the elevator car guide rails are configured to follow the relative displacement between the lower layer and the upper layer through the seismic isolation device. Proposals have been made so as not to block the hoistway (see Japanese Patent Laid-Open Nos. 9-278315, 10-231075, and 11-29277).
[0004]
[Problems to be solved by the invention]
However, in the invention described in Japanese Patent Application Laid-Open No. 9-278315, a rail support member having ball seat joints at upper and lower ends is supported on an intermediate layer having a seismic isolation device in a swingable manner. The rail is supported and fixed, and the upper and lower ends of the intermediate rail are swingably connected to the upper and lower rails with ball joints or deformable connection rails, so the structure is simple but reliable. There is a lack of safety.
[0005]
Further, in the invention described in Japanese Patent Application Laid-Open No. 10-231076, a supporting column support beam is provided across the high-rise building and the low-rise building with the seismic isolation device interposed therebetween, and the lifting support is supported by this support column beam. Since the guide rail is supported by the lifting support, it is expected that the reliability and safety will be improved with a robust structure, but the construction cost is high and there is a disadvantage in terms of economy.
[0006]
Further, in the invention described in Japanese Patent Application Laid-Open No. 11-29277, reinforcing struts are installed in parallel on both sides of the guide rail separately from the guide rail over a plurality of levels including the seismic isolation floor, and the upper and lower ends of the reinforcing strut are upper layers. And the lower layer are supported so that they can swing back and forth, left and right, and a lateral beam is connected between the reinforcing columns to form a substantially parallelogram frame, and a guide rail is slidably attached to the lateral beam. The frame is deformed in a parallel link state relative to the relative displacement, and the elastic deformation of the guide rail is promoted, but the upper and lower ends of the reinforcing column are supported on the upper and lower layers so that they can swing back and forth and left and right respectively. Since the structure to be constructed is complicated and requires time and labor for construction work, there is a drawback that the construction cost increases.
[0007]
Thus, the present invention provides an elevator hoistway for a base-isolated building that can keep construction costs low and that is highly reliable and safe.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 is an elevator hoistway that communicates between a lower layer and an upper layer of a building with a seismic isolation device, and a rectangular rigid frame is provided in the elevator hoistway. In the elevator hoistway of the seismic isolation building in which the lower layer is supported by the upper layer so that it can swing on the lower layer via an elastic machine, and the guide rail of the elevator car is locked to the rigid frame ,
There are provided stoppers that are connected to the substantially central part between the upper side of the rigid frame and the upper support member and the substantially central part between the lower side of the rigid frame and the lower support member, respectively, so as to be freely movable. It was .
[0009]
The invention according to claim 2 is an elevator hoistway that communicates between a lower layer and an upper layer of a building with a seismic isolation device, and has a rectangular rigid frame body in the elevator hoistway with its upper end at the upper layer and lower end at the lower layer In the elevator hoistway of a seismically isolated building, each of which is supported in a swingable manner via an elastic machine and the guide rail of the elevator car is locked to the rigid frame, the four rigid frames are formed into a cubic shape. They are connected to form an integral rigid fence frame, and this rigid fence frame is interposed in the hoistway between the lower layer and the upper layer so as to be swingable via an ammunition, and an elevator car guide rail is placed in the rigid fence frame. It was locked through an absorber.
[0011]
Thus, since the rigid frame or rigid frame was placed via the ammunition in the elevator hoistway between the lower layer and the upper layer that intervened the seismic isolation device, even if relative displacement between the layers occurred during the earthquake, As the guide frame is absorbed, the guide frame is swung while the rigid frame body or the rigid saddle frame is not deformed, so that the guide rail can be prevented from being deformed or broken to prevent the elevator from moving up and down.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0013]
The first embodiment configured for the above purpose will be described. As shown in FIGS. 1 and 2, a rectangular rigid frame 4 is swung between the lower layer 2 and the upper layer 3 with the seismic isolation device 1 interposed therebetween. The guide rail 5 is supported on the rigid frame 4 by being fixed as possible. The guide rails 5 guide the elevator car to be lifted and are provided in pairs facing each other in the hoistway.
[0014]
The rigid frame 4 is composed of a parallelogram-shaped vertically long frame, and has at least two transverse beams 6 arranged vertically in the inside thereof. Preferably, the rigid frame 4 is rigid by incorporating a plurality of oblique truss members. So that the parallelogram is not easily deformed.
[0015]
At least two suspension support rods 8 and 8 made of long bolts having threaded portions at both ends are loosely fitted and passed through the upper side 4a and the lower side 4b of the rigid frame 4, respectively. Although the suspension support rods 8 are illustrated as two in the upper and lower directions, they may be three or four, and the arrangement thereof is the same line in a straight line, but is not limited thereto.
[0016]
On the upper side 4a side, the upper end portion side of the suspension support bar 8 is loosely fitted through the upper support member 9 fixed to the upper layer 3 and the pedestal 10 placed thereon, and is inserted through a spring 11 such as a coil spring. The nut 13 is fastened with a washer 12 abutting against the bullet machine 11, while the lower end of the washer 12 is inserted into the inner side of the rigid frame 4 and fastened with the nut 13.
[0017]
On the lower side 4b side, the upper end side of the suspension support bar 8 is inserted into the inner side of the rigid frame 4 with a washer 17 and fastened with a nut 18, while the lower end side is fixed to the lower layer 2 with the lower support member 14 fixed thereto. A pedestal 15 placed thereon is loosely fitted and penetrated, and a bullet machine 16 such as a coil spring is inserted, and a nut 18 is fastened with a washer 17 in contact with the bullet machine 16 interposed.
[0018]
The upper support member 9 and the lower support member 14 are formed of an angle member and a plate welded thereto, and are provided so as to protrude into the elevator hoistway. The bases 10 and 15 are mounted on the upper support member 9 and the lower support member 14 so as to be fixed or slidable in the horizontal direction. Since the suspension support rods 8, 8 penetrate the bases 10, 15 so as to be movable in the axial direction, the suspension support rods 8, 8 can move up and down.
[0019]
Further, stoppers 20 and 20 are provided at substantially the center portions of the upper side 4a and the lower side 4b of the rigid frame 4, respectively. As shown in a circle in FIG. 2, the stopper 20 is fitted in the outer cylinder 21 fixed to the bases 10 and 15 with the piston rod 22 fixed to the upper support member 11 and the lower support member 14 in the axial direction. At the tip of the piston rod 22, a head 23 that can move in the axial direction in the outer cylinder 21 is provided to form a pneumatic cylinder.
[0020]
Therefore, the rigid frame 4 can swing with respect to the relative displacement between the upper layer 3 and the lower layer 2 without being deformed itself. Further, excessive movement of the rigid frame 4 can be restricted by the stoppers 20 and 20.
[0021]
A guide rail 5 extending from the lower layer 2 to the upper layer 3 is slidably fixed to the cross beam 6 of the rigid frame 4 by a pair of clamping members 30 and 30. The clamping member 30 is made of an elongated sheet metal having offset ends, and one end thereof is fixed to the cross beam 6 by welding, and the other end is pressed against one side of the iron floor portion of the guide rail 5 having a T-shaped cross section. However, the guide rail 5 is regulated to be movable in the vertical direction and the horizontal direction.
[0022]
Therefore, when relative displacement occurs between the lower layer 2 and the upper layer 3, as shown in FIG. 3, for example, the seismic isolation device 1 tilts to the right, and the upper mounting member 9 moves to the right with respect to the lower mounting member 14. When the suspension supports 8 and 8 are moved in the axial direction, the elastic machines 11 and 16 engaged with the upper and lower suspension supports 8 and 8 are compressed and expanded to allow the movement. As shown in FIG. 4, for example, when the seismic isolation device 1 tilts rearward and the upper mounting member 9 moves rearward with respect to the lower mounting member 14, the suspension support rods 8 and 8 move in the axial direction. Thus, the bullets 11 and 16 engaged with the upper and lower suspension support rods 8 and 8 are compressed and expanded to allow the movement thereof.
[0023]
Therefore, the rigid frame 4 can follow the relative displacement between the layers without being deformed and without destroying the guide rail 5. In addition, excessive movement of the rigid frame 4 is prevented by the stoppers 20 and 20 acting so as to restrict them.
[0024]
Next, a second embodiment of the present invention will be described. As shown in FIG. 5, a rigid saddle frame 40 is oscillated between a lower layer 2 and an upper layer 3 with the seismic isolation device 1 interposed therebetween via an ammunition 42. The guide rail 50 is fixed to the rigid rod frame 40 and connected to the guide rails 5 and 5 provided in the lower layer 2 and the upper layer 3 so as to be swingable via an absorber 41 as shown in FIG.
[0025]
The rigid saddle frame 40 is a rigid body obtained by combining the four rigid frame bodies 4 in a cubic shape as described above, and an elastic machine 42 such as a coil spring is provided at each corner of the upper and lower ends of the rigid frame body 40. At least three of them are arranged in the three-dimensional direction of Z, and these bullets 42 are applied to the inner side surface and the inner upper surface of the rigid saddle frame storage portions 43, 44 formed on the lower layer 2 and the upper layer 3, or the inner side surface and the inner lower surface. By being brought into contact therewith, it is fixed in a state of being floatably floated in the rigid saddle frame storage portion 43.
[0026]
The absorber 41 that supports the guide rail 50 in the rigid rod frame 40 includes, for example, an eyebolt-shaped support rod 46 that is pivotally supported on both ends of a base 45 fixed to the inner wall of the rigid rod frame 40, and the guide rail 50. An eyebolt-shaped support rod 47 pivotally supported by a bracket 49 for fixing the shaft engages with both ends of the cylinder 48, and a spring is connected to the support rods 46, 47 in the cylinder 48 so as to be extendable and contractible. It is.
[0027]
Four of the absorbers 41 are connected to a bracket 49 and expanded in an up-down direction in an eight-letter shape to be connected and fixed to pedestals 45 and 45 (see FIG. 8A). Therefore, when the guide rail 50 is pushed to the rigid saddle frame 40 side, it is buckled to the rigid saddle frame 40 side as shown in FIG. To prevent.
[0028]
Therefore, when relative displacement occurs between the lower layer 2 and the upper layer 3, the rigid saddle frame 40 swings corresponding to the displacement between the layers as shown in FIG. Absorbed at In this case, in order to prevent the guide rail 50 from being destroyed, the connection portions 51 and 51 with the upper and lower guide rails 5 are connected by using ball joints or appropriate deformable connection joints.
[0029]
In this way, the rigid frame 4 or the rigid frame 40 which is a developed form of the rigid frame 4 is arranged to swing relative to the relative displacement between the layers in the base-isolated building, thereby preventing the guide rails 5 and 50 of the elevator car 52 from being broken. As a result, it is possible to smoothly operate the elevator hoistway of the seismic isolation building during the earthquake without causing the elevator hoistway to move up and down, thereby improving safety.

【The invention's effect】
According to the present invention described above, the rigid frame body or the rigid frame is disposed in the elevator hoistway between the lower layer and the upper layer via the seismic isolation device, so that the construction cost can be kept low. In addition, since the guide rail is supported by a rigid body, an elevator hoistway for a base-isolated building with high reliability and safety can be obtained.
