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

【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.
