Description

【０００１】
【発明の属する技術分野】
本発明は、上下階床に跨って設置されるエスカレーターあるいは動く歩道等の乗客コンベアに係り、特にその下部本体枠を支持するに好適な構成に関する。
【０００２】
【従来の技術】
一般に、駅ホーム等に設置される長い乗客コンベアは、例えば、実開昭51− 116591号公報に記載のように、上下階床間をトラス構造体等の本体枠が跨ぐように設置されるもので、その上階側は上階床の構築物に、その下階側は下階床の構築物に、上下階床間の中間点は独立した構築物にそれぞれ支持される構成となっている。
【０００３】
【発明が解決しようとする課題】
上記従来の支持構成は、乗客コンベアの長手方向を上階床，下階床及び中間点の３箇所で本体枠を支持して構成装置と乗客の全重量を集中的に負担する構成となっていた。そして、通常１０トン以上にもなる全体重量を支持するための土木あるいは建築の高強度構築部を上記３箇所に分散して施工しなければならず、乗客コンベア設置上の工期とコストが隘路とされ、その解決が望まれていた。
【０００４】
本発明の目的とするところは、土木あるいは建築による高強度構築部の数を減らして施工に要する期間とコストを縮減できる乗客コンベアの本体枠を提供することにある。
【０００５】
【課題を解決するための手段】
本発明は上記目的を達成するために、上階床と下階床の間に下部枠体，傾斜部枠体及び上部枠体を連結して配置される本体枠と、この下部枠体の上面を形成する下部水平床と、この上部枠体の上面を形成する上部水平床を備え、この下部水平床の下側の下部枠体と傾斜部枠体の一部が、下階床に構築されたＵ字溝状のピットに収納されるものにおいて、前記傾斜部枠体の底部の一部を、水平部と鉛直部で形成し、前記本体枠の下部側の底部を、前記下部枠体の底部から前記傾斜部枠体の底部の一部にかけて水平に連続する水平底部となし、この水平底部全体を前記ピット内の土木床に載置して設置し、前記本体枠を中間点で支持せずに上階床と下階床側で支持する構成としたのである。
【０００６】
上記構成によれば、本体枠の下部側の底部が、下部枠体の底部から傾斜部枠体の底部の一部にかけて水平に連続する水平底部を形成し、この水平底部全体が上記ピット内の土木床上に直接的に載置されるので、乗客コンベア側及び構築側とも大型の支持柱や支持構造物が不要となる。また、上記水平底部により本体枠の下部側の広い面積が支持されるので、従来の下階床と中間点２箇所分をピット内１箇所に集約でき、実質的に従来比２／３相当の上階床と下階床側の高強度構築だけで支持できる構成となって、その施工期間，必要コストの両面で大幅な改善を図ることができる。
【０００７】
【発明の実施の形態】
以下、本発明の一実施の形態を図１〜図３について説明する。乗客コンベア１は、下階床Ｆ１と上階床Ｆ２に跨って設置され、この両階床Ｆ１とＦ２を下部枠体２Ａ，傾斜部枠体２Ｂ及び上部枠体２Ｃを連結した形の本体枠２と、この下部枠体２Ａの上面を形成する下部水平床３と、この上部枠体２Ｃの上面を形成する上部水平４と、この両水平床３及び４の間を周知の無端チェーン（図示せず）によって無端状に連結されて移動する踏段５と、この踏段５の下部曲線路５Ａ，傾斜路５Ｂ，上部曲線路５Ｃの連続側壁を形成する欄干６と、側壁の手摺となるハンドレール７等で構成されている。ここで、本体枠２の下部側は、下部水平床３の下部枠体２Ａの底部２ＡＡから傾斜部枠体２Ｂの底部２ＢＢの一部にかけて連続的に水平に延長された形の水平底部２Ｄとなっていて、この水平底部２Ｄ部分の全てが、下階床Ｆ１に側壁８Ａ，８Ｂと土木床８ＣでＵ字溝状に構築されたピット８の深さＨ，長さＬ４の範囲内に収納されている。一方、この本体枠２の上部枠体２Ｃは、図２に示すように土木あるいは建築による構築梁９の上に、調整板１０を介した状態で本体枠２の端部２ａに固定された梁体２ｂが重なり代Ｌ１をもって装架，設置されている。さらに、本体枠２の下部側は、従来と同様な下部の水平部長さＬ５（図３）に対して傾斜部枠体２Ｂ側に水平底部長さＬ６（図３）分を延長して水平底部２Ｄを形成したもので、従来の傾斜部枠体の底部（図３の想像線Ｘ）の一部を失くして垂直高さｈ分を新たに追加した形の一体的トラス構造（図３）となっている。この場合、水平底部２Ｄと土木床８Ｃとの間には、この水平底部２Ｄに固設された受座２ＡＡＡと２ＢＢＢが設けられ、これと対向した位置の土木床８Ｃに固設されて支持台１１，１２との間に摺動体１３と
１４を介した形で設けられている。そして、地震などで本体枠２の下部側が滑動した場合に、この摺動体１３と１４が受座２ＡＡＡ，２ＢＢＢと支持台１１，
１２との間の摺動抵抗を減じる仕組みとなっている。また、この本体枠２の底面は外装板１５（図３）によりピット８の開口部と共に被覆されるものである。
【０００８】
上記のようにしたことにより、乗客コンベア１の本体枠２の全長Ｌ（図１）の上部側が構築梁９に、下部側がピット８の中の支持台１１，１２で支持されるので、この乗客コンベア１の設置に要する土木あるいは建築の構築工事が実質的に２箇所（従来は３箇所に分散）に集中化される。また、支持台１１，１２による本体枠２の下部側の支持が２箇所一括支持となり、これの間隔Ｌ２(図１，図３)が全長Ｌを減じて支持点間隔をＬ３（図１）とならしめるため、従来の中間点
（図１の想像線Ｙの位置）での支持構築が不要となる効果がある。さらに、本体枠２の下部側の重量が水平底部２Ｄにより土木床８上の広い面積に分散される形となるので、単位面積当たりの荷重負担が少ない構築工事で対応できる利点がある。
【０００９】
【発明の効果】
以上説明したように本発明によれば、土木あるいは建築による高強度構築部の数を減らすことができ、施工に要する期間とコストを縮減できる乗客コンベアの本体枠の構成を提供することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a passenger conveyor such as an escalator or a moving sidewalk installed across upper and lower floors, and more particularly to a configuration suitable for supporting the lower body frame.
[0002]
[Prior art]
In general, long passenger conveyors installed in station platforms, etc., are installed such that a body frame such as a truss structure straddles between the upper and lower floors, as described in Japanese Utility Model Publication No. 51-116591, for example. The upper floor side is supported by an upper floor structure, the lower floor side is supported by a lower floor structure, and the midpoint between the upper and lower floors is supported by an independent structure.
[0003]
[Problems to be solved by the invention]
The conventional support structure is configured to support the main body frame in the longitudinal direction of the passenger conveyor at three locations of the upper floor, the lower floor, and the middle point to intensively bear the total weight of the component device and the passenger. It was. And civil engineering or architectural high-strength construction parts for supporting the overall weight of usually 10 tons or more must be distributed and constructed in the above three locations, and the construction period and cost on passenger conveyor installation are The solution was desired.
[0004]
An object of the present invention is to provide a passenger conveyor main body frame capable of reducing the number of high-strength construction parts by civil engineering or construction to reduce the time and cost required for construction.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention forms a main body frame arranged by connecting a lower frame, an inclined frame and an upper frame between an upper floor and a lower floor, and an upper surface of the lower frame. A lower horizontal floor and an upper horizontal floor forming the upper surface of the upper frame, and a lower frame and a part of the inclined part frame on the lower side of the lower horizontal floor are constructed on the lower floor. In what is housed in the groove-shaped pit, a part of the bottom portion of the inclined portion frame body is formed by a horizontal portion and a vertical portion, and the bottom portion on the lower side of the main body frame is formed from the bottom portion of the lower frame body. A horizontal bottom part that is horizontally continuous over a part of the bottom part of the inclined part frame body, and the entire horizontal bottom part is placed on the civil floor in the pit, and the main body frame is not supported at an intermediate point. It is configured to support the upper floor and the lower floor .
[0006]
According to the above configuration, the bottom portion of the lower side of the main body frame forms a horizontal bottom portion that extends horizontally from the bottom portion of the lower frame body to a part of the bottom portion of the inclined portion frame body, and the entire horizontal bottom portion is in the pit. Since it is directly placed on the civil engineering floor, large support pillars and support structures are unnecessary on the passenger conveyor side and the construction side. Further, since the large area on the lower side of the main body frame is supported by the horizontal bottom portion, the conventional lower floor and two intermediate points can be concentrated in one place in the pit, substantially equivalent to 2/3 of the conventional one. The construction can be supported only by the high-strength construction on the upper and lower floors, and it can greatly improve both the construction period and required cost.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. The passenger conveyor 1 is installed across the lower floor F1 and the upper floor F2, and the main body frame is formed by connecting both the floors F1 and F2 to the lower frame 2A, the inclined portion frame 2B, and the upper frame 2C. 2, a lower horizontal floor 3 that forms the upper surface of the lower frame 2A, an upper horizontal 4 that forms the upper surface of the upper frame 2C, and a well-known endless chain (see FIG. A step 5 that is connected endlessly by a notch), a balustrade 6 that forms a continuous side wall of the lower curved path 5A, the inclined path 5B, and the upper curved path 5C of the step 5, and a handrail that serves as a handrail of the side wall 7 etc. Here, the lower side of the main body frame 2 has a horizontal bottom 2D that is continuously extended horizontally from the bottom 2AA of the lower frame 2A of the lower horizontal floor 3 to a part of the bottom 2BB of the inclined frame 2B. All of the horizontal bottom 2D portion is stored in the range of depth H and length L4 of the pit 8 constructed in a U-shaped groove shape on the lower floor F1 with the side walls 8A and 8B and the civil engineering floor 8C. Has been. On the other hand, the upper frame 2C of the main body frame 2 is a beam fixed on the end 2a of the main body frame 2 on the construction beam 9 made of civil engineering or construction as shown in FIG. The body 2b is mounted and installed with an overlap margin L1. Further, the lower side of the main body frame 2 extends the horizontal bottom length L6 (FIG. 3) to the inclined portion frame body 2B side with respect to the lower horizontal portion length L5 (FIG. 3) as in the conventional case. An integrated truss structure (Fig. 3) in which a part of the bottom of the conventional inclined portion frame (imaginary line X in Fig. 3) is lost and a vertical height h is newly added. It has become. In this case, receiving seats 2AAA and 2BBB fixed to the horizontal bottom 2D are provided between the horizontal bottom 2D and the civil engineering floor 8C, and are fixed to the civil floor 8C at a position facing the same. 11 and 12 are provided in the form of sliding bodies 13 and 14 interposed therebetween. When the lower side of the main body frame 2 slides due to an earthquake or the like, the sliding bodies 13 and 14 are connected to the seats 2AAA, 2BBB and the support base 11,
12 is a mechanism for reducing the sliding resistance between the two. The bottom surface of the main body frame 2 is covered with the opening of the pit 8 by the exterior plate 15 (FIG. 3).
[0008]
By doing as mentioned above, since the upper part side of the full length L (FIG. 1) of the main body frame 2 of the passenger conveyor 1 is supported by the construction beam 9 and the lower part is supported by the support bases 11 and 12 in the pit 8, this passenger The construction work of the civil engineering or building required for the installation of the conveyor 1 is substantially concentrated at two locations (conventionally distributed at three locations). Further, the support on the lower side of the main body frame 2 by the support bases 11 and 12 is collectively supported at two places, and the distance L2 (FIGS. 1 and 3) decreases the total length L and the distance between the support points is L3 (FIG. 1). Therefore, there is an effect that the support construction at the conventional intermediate point (the position of the imaginary line Y in FIG. 1) becomes unnecessary. Furthermore, since the weight on the lower side of the main body frame 2 is distributed over a wide area on the civil engineering floor 8 by the horizontal bottom 2D, there is an advantage that it can be handled by construction work with a small load load per unit area.
[0009]
【The invention's effect】
As described above, according to the present invention, it is possible to provide the configuration of the main body frame of the passenger conveyor that can reduce the number of high-strength construction parts by civil engineering or construction and can reduce the time and cost required for construction.
