【発明の属する技術分野】
本発明は、乗客コンベアと階段体からなる通路設備に係り、特に、乗客コンベアを階段体に設置する場合に好適な構成に関する。
【０００２】
【従来の技術】
一般に、建築構造物の歩行者通路である階段部分に乗客コンベアを設置して通路設備を形成する場合、乗客コンベアの乗降床を上下階床と一致させるために、階段の一部および上下階床を取壊して掘り起こし、そこに主枠を埋没させるようにする一方、この主枠の強度保持手段としてその長手方向のほぼ中央部を主枠の底部から下階床まで達する中間支持で支持するようにしている（特開平７−１７９２８２号公報）。
【０００３】
【発明が解決しようとする課題】
上記従来の通路設備は、乗客コンベアの既設階段への設置に際し、特に中間支持部の工事量削減に対する配慮がなく、中間支柱立設部の基礎工事が大掛かりとなるなど設置付帯工事の期間と経済性の両面で問題があった。
【０００４】
本発明の目的は、乗客コンベアの設置に際し、工期短縮と費用削減の効果を有する、乗客コンベアと階段体からなる通常設備を提供することにある。
【０００５】
【課題を解決するための手段】
上記目的を達成するために本発明は、上部水平部と下部水平部間に傾斜部を有する主枠と、無端状に連結されて前記主枠内を循環移動する複数の踏段と、これら踏段の移動方向両側に沿って位置し、前記主枠に支持される左右の欄干と、これら欄干の周縁に案内され、前記踏段と同期して移動する移動手摺等からなる乗客コンベアを、階段体とこの階段体の下方両側に配置されて階段体を強度保持する複数の梁体上に設置した通路設備において、前記複数の梁体同士を補強体で接合して前記複数の梁体を補強し、かつこの補強体の上側に前記主枠を支持する支持体を設けたのである。
【０００６】
また、前記支持体は、前記階段体を貫通する形で前記補強体上に載置される構造としたのである。さらに、前記支持体は、前記階段体の裏側に密着して設けられた前記補強体に対して、前記階段体の厚さを隔てた形で前記主枠を支持する構成としたのである。
【０００７】
上記構成によれば、階段体の下方両側に配置された頑丈な複数の梁体同士を補強体で接合補強し、かつこの補強体で直接的に主枠を支持する構成であるので、従来のように乗客コンベアの底部から垂直に下階床まで達する長尺の中間支柱が不要となり、工事量と工期の縮減、工事費用の低減を図ることができる。
【０００８】
【発明の実施の形態】
以下、本発明の一実施の形態を図１と図２に基づいて説明する。一般に、大型ビルや駅舎などの多層構造物１には、上階床２と下階床３に跨って階高の高い階段体４が設けられている。この階段体４は、途中に中間踊り場５を有し、その上下に連なって上側階段部６と下側階段部７とが形成され、さらにこの階段体４の下方両側に配置されて、それの強度を保持する複数（両側に２本、場合によっては中央にも１本設けられている）の梁体８によって支持されている。上記階段体４は、上階床２に形成した吹き抜け９を利用して設置されており、この吹き抜け９の周囲には、階段体４の折り口を除いて柵、手摺、仕切り壁などの防護手段９Ａが設けられて通行者の吹き抜け９からの転落事故を防いでいる。
【０００９】
このような階段体４に、高齢者などの歩行弱者を重視し、エスカレーター式乗客コンベア１０を併設する気運が高まってきている。そこで、階段体４の全幅方向の片側に寄せて乗客コンベア１０を上階床２と下階床３に跨って設置している。
【００１０】
この乗客コンベア１０は、主枠１１をベースに構成されている。この主枠１１は、左右一対の側枠体１２Ａ、１２Ｂを有し、これら側枠体１２Ａ、１２Ｂは、各々上弦材１３および下弦材１４とこれらを連結する縦部材１５、横部材１６、それに底板１７で箱形状を形成している。さらに、このような部材で構成された主枠１１は、上部水平部１８と下部水平部１９と傾斜部２０とを有し、上部水平部１８は上部機械室１８Ａとなり、下部水平部１９は下部機械室１９Ａとなる。
【００１１】
上記のように構成された主枠１１の内部には、一対の踏段チェーン（図示省略）に連結された複数の踏段２１が配置され、これが往路と復路を循環して乗客輸送する仕組みになっている。踏段２１は、幅方向両側に張出した前輪軸２２に回転自在に軸支された一対の前輪２３Ａ、２３Ｂと、前輪２３Ａ、２３Ｂよりも狭い間隔で軸支された一対の後輪２４Ａ、２４Ｂを備えている。これら前輪２３Ａ、２３Ｂ等は、前記主枠１１に支持された各案内レール２５、２６上を転動して踏段２１を所定軌跡で移動させる。
【００１２】
一方、上記構成の主枠１１の上部には、踏段２１の移動方向に沿って左右一対の欄干２７が設けられている。この欄干２７は、主枠１１に支持される欄干パネル２８Ａ、２８Ｂと、この欄干パネル２８Ａ、２８Ｂの周縁に案内されて踏段２１と同期して移動する無端状の移動手摺２９Ａ、２９Ｂと、欄干パネル２８Ａ、２８Ｂの基部を被う内デッキカバー３０Ａ、３０Ｂと、移動手摺２９Ａ、２９Ｂの外側を被う外デッキカバー３１Ａ、３１Ｂ等を備えている。さらに、主枠１１、欄干２７の外側は勿論、主枠１１と階段体４との上下方向間の外表面は、乗客コンベア１０に支持され、化粧仕切り体を形成する外装板３２で被われている。
【００１３】
そして、上記構成の乗客コンベア１０を中間踊り場５を有する既設の階段体４に設置する場合、この階段体４の中間踊り場５よりも下方の下側階段部７上に、その傾斜角度にほぼ沿わせて主枠１１を配置し、この状態で主枠１１の上部機械室１８Ａおよび下部機械室１９Ａの上側の乗降床が多層構造物１の上階床２および下階床３と面一になるように、上部水平部１８側においては上側階段部６の一部を斫り（掘り起こし）、下部水平部１９側においては下階床３を斫って埋設する。
【００１４】
さらに、階段体４の骨部材となる梁体８は、この階段体４の全長方向に連続して、その下方両側に複数（図２は左側の一本のみを示す）配置されるものであるが、本発明の構成では、全長方向の要所に頑丈な補強体３３を追加、接合（接合部ｍ）して、梁体８同士が複合して全体強度を高める構成となっている。また、この補強体３３の上面には、主枠１１の底部に固定的に接合（接合部ｎ１）された支持体３４、台座３５とが設けられ、この支持体３４は補強体３３にも接合（接合部ｎ２）される構成となっている。この場合、支持体３４は、階段体４に設けられた穴４Ａを貫通する形で配置されるもので、乗客コンベア１０の全体重量の一部を補強体３３に負担させる。また、支持体３４は、主枠１１の撓み（負荷による沈下）を防止するために必要に応じて、必要本数だけ配置されるものであり、この支持体３４と対をなして補強体３３も追加、配置されるものである。
【００１５】
このように、梁体８の補強を兼ねた補強体３３で主枠１１を支持することにより、従来のような長尺の中間支柱とそれを支持する大規模な基礎工事が不要となり、当然、労力と作業期間（工期）、それに工事費用の削減を図ることができる。 上記図１、図２の例は、支持体３４が穴４Ａを貫通する構成であるが、本発明は図２の構成とは異なる応用例も考えられる。例えば、図３の例は、補強体３６を階段体４の裏側に符号Ｙ部で密着させて配置し、この段階体４（厚さＨ）を上下方向に挟むように支持体３７を設けたものである。この場合、上記の穴４Ａの施工が不要となる効果が加わる。なお、上記の支持体３４、３７は柱状のものに限定されるものではなく、背の低い板状あるいは台状のものでも何ら不都合はない。加えて、上記の補強体３３は、梁体８の下側に符号３８のように接合する構造でも上記と同様の効果を奏する。
【００１６】
上記説明は、通常のエスカレーター式乗客コンベア１０に限定しているが、これに車いす運転機能を付加した特殊型や上記踏段２１のように段差を有しない動く歩道の場合にもそのまま適用することができる。
【００１７】
【発明の効果】
このように本発明によれば、乗客コンベアの設置に際し、工期短縮と費用削減の効果を有する乗客コンベアと階段体からなる通路設備を提供することができる。
