Description

【０００１】
【発明の属する技術分野】
本発明は、エレベータの乗り場の開口枠の取付け構造に関するものである。
【０００２】
【従来の技術】
エレベータ乗り場の開口部には、開口部の後部に戸を開閉自在に取付けた開閉装置枠が取付けられる。この開閉装置枠は上レール枠と下レール枠と両側の縦枠とを枠組みして枠組み内に戸を移動自在に内装したもので、この開閉装置枠をエレベータ乗り場の開口部の後部に取付けた場合、開閉装置枠の横方向の一部が開口部の隣りの壁下地材の後面側に位置して戸袋部となっている。つまり、開閉装置枠に取付けた戸を閉じた際にはエレベータ乗り場の開口部を閉じ、戸を移動して戸袋部内に位置させた際にはエレベータ乗り場の開口部を開放するようになっている。
【０００３】
そして、門型をした開口枠をエレベータ乗り場の開口部に配置して開閉装置枠の戸袋部を除く前面側に配設して取付けることで、開口部の周囲を構成するようにしている。
開閉装置枠４の下レール枠２は図１６に示すように建物の梁のような構造材２２に取付けた下基材３４に取付けてある。そして、この下レール枠２から前方に向けて先端が自由端となった載置片６０が突出してある。上記した門型の開口枠１１は、図１５に示すように開閉装置枠４の下レール枠２の前面側から前方に突出した先端が自由端となった載置片６０に載置し、載置片６０に設けた位置決め凸部６１を開口枠１１の下端面部に設けた係止孔６２に係止することで、開口枠１１の下端部を位置決め保持するようにしていた。
【０００４】
ところが、開口枠１１の下端部は下レール枠２の上面と略面一となるように図１６のように取付けられる。これは、エレベータ工事の時にはエレベータ乗り場の床には床面となる床材は未だ施工してなく、エレベータ工事終了後（つまり開口枠１１の取付け後）に、エレベータ乗り場５の床下地上に床材が施工される、この床材が開口枠１１部分においては開口枠１１の下面側に差し込まれようにして施工されるものであり、このため、開口枠１１の下端部が床材の上面と略面一となる下レール枠２の上面と略面一となるように建て込むものである。
【０００５】
しかして、開口枠１１を開閉装置枠４の下レール枠の前面側から前方に突出した載置片６０に載置する場合、載置片６０が下方に撓んで開口枠１１の下端部を正確な高さ関係となるように位置決めして保持することができないので、位置合わせが難しく、また、載置片６０が下方に撓むことで位置決め凸部６１と係止孔６２との係止が外れてしまって開口枠１１の下端部の保持ができないという問題がある。
【０００６】
【発明が解決しようとする課題】
本発明は上記の従来例の問題点に鑑みて発明したものであって、門型をした開口枠の両側下端部を簡単な構成で正確且つ強固に位置決め保持でき、また、開口枠の下端部を挟持するために差し込む作業が容易に行え、更に、両門型をした開口枠の自由端部となった両側下端部間の寸法が正確な寸法となるように正確に位置決め保持することができるエレベータの乗り場の開口枠の取付け構造を提供することを課題とするものである。
【０００７】
【課題を解決するための手段】
上記課題を解決するために、本発明のエレベータの乗り場の開口枠の取付け構造は、上レール枠１と下レール枠２と両側の縦枠３とを枠組みして枠組み内に戸４ａを移動自在に内装した開閉装置枠４を構成し、この開閉装置枠４をエレベータ乗り場５の開口部６の後部に取付けると共に開閉装置枠４の横方向の一部を開口部６の隣りの壁下地材７の後面側に位置させて戸袋部８とし、両側の外縦枠９と上枠３６とで門型に枠組みされ且つ外縦枠９の内面側に沿って額縁用縦枠１０を取付けて門型をした開口枠１１を構成し、この開口枠１１をエレベータ乗り場５の開口部６に配設して開閉装置枠４の戸袋部８を除く前面側に配設して取付けるものであって、額縁用縦枠１０の背面側において一側方及び後方が開口した額縁用縦枠１０の側端部と後端部とにわたって水平断面Ｌ字状をした取付け金具１２を上下方向に複数個架設し、この水平断面Ｌ字状をした取付け金具１２の外縦枠９と対向する片と外縦枠９とを固着し、下レール枠２の開口部６の下基材３４との間に挟着されたブラケット１３の前端部に前縦片１４と後縦片１５とを近接対向して突設して挟持部１６を形成すると共に、ブラケット１３の前端部の挟持部１６の隣りに立ち上がり突片１８を上方に向けて突設し、門型の開口枠１１の両側の額縁用縦枠１０に設けた最下段の取付け金具１２の下レール枠２に沿った片をそれぞれ挟持部１６に嵌め込み挟持すると共に両側の額縁用縦枠１０の後端部の下端部の内側に立ち上がり突片１８を差し込んで成ることを特徴とするものである。このような構成とすることで、門型の開口枠１１の両側下端部をそれぞれ挟持部１６による挟持保持と、立ち上がり突片１８による位置決め保持との両方で保持できて、門型の開口枠１１の両側下端部を位置決めした状態で保持できるものである。そして、額縁用縦枠１０の下端部と、額縁用縦枠１０を保形し且つ額縁用縦枠１０を外縦枠９に連結するための骨材となる取付け金具１２の２箇所が保持されることとなって、門型の開口枠１１の両側下端部を位置決め保持が確実となるものである。
【０００８】
また、挟持部１６の後縦片１５を前縦片１４よりも上方に長く突出することが好ましい。このような構成とすることで、後縦片１５をガイドとして挟持部１６に取付け金具１２の一片を簡単に差込んで挟持させることができることになる。また、下レール枠２の開口部６の下基材３４との間に挟着されたブラケット１３を長尺の連結板１９の両側に形成することが好ましい。このような構成とすることで、両側のブラケット１３間の長さを設計通りの一定寸法とすることができて、両側のブラケット１３において挟持して保持される門型の開口枠１１の両側下端部間の長さが一定となるように施工することができるものである。
【０００９】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
建物内には図１３、図１４に示すようなエレベータ昇降路２０が形成される。このエレベータ昇降路２０の内部にはエレベータかご装置２１が昇降自在に配置してある。エレベータ昇降路２０内の幅方向の一側部の前後には一対のガイドレール２４ａが立設してあり、建物の構造材２２に補強枠２３が固着してある。この補強枠２３にレールブラケット２４を固着し、レールブラケット２４に上記一対のガイドレール２４ａが取付けてある。また、ガイドレール２４ａの下端部は図１３に示すようにエレベータ昇降路２０の底面のコンクリートスラブ２５上に固着したスタンド２６に連結してある。スタンド２６の中央部には更に油圧シリンダ２７の下端部が取付けてある。
【００１０】
エレベータかご装置２１はＬ字状をしたプラットホーム２８の横枠部２８ａにかご体２９を載設して構成してある。Ｌ字状をしたプラットホーム２８の縦枠部２８ｂの前後方向の上部と下部とのそれぞれ４箇所にはそれぞれガイド部材３０が設けてあり、前後両側に立設したガイドレール２４ａにそれぞれガイド部材３０が上下移動自在に摺動自在にはめ込んである。更に、プラットホーム２８の縦枠部２８ｂの中央部に油圧シリンダ２７のロッドの上端部が固着してある。ガイド部材３０は滑性に富んだ合成樹脂により形成してあって、滑りを良くしてある。そして、油圧シリンダー２７を駆動させることで、エレベータかご装置２１を昇降するようになっている。この場合、ガイド部材３０はガイドレール２４ａに沿ってガイドされながら移動することで、エレベータかご装置２１がスムーズに昇降することになる。
【００１１】
エレベータかご装置２１のかご体２９の前面部側には出入り口用開口が設けてあって、該出入り口用開口に開閉自在な戸装置３１が設けてある。
図３、図４に示すように、各階のエレベータ乗り場５にはそれぞれ開口部６が形成されるものであり、この開口部６の後部側に戸４ａを開閉自在に取付けた開閉装置枠４が取付けられる。開閉装置枠４は金属製の上レール枠１と、金属製の下レール枠２と、両側の金属製の縦枠３とを枠組みして構成してあり、上レール枠１には戸４ａの上端部の吊りランナ３２が設けてあり、図示を省略している駆動装置により戸４ａを上レール枠１に沿って移動できるように構成してある。戸４ａの下端部には走行ガイド３３が設けてあって、この走行ガイド３３が下レール枠２のレール溝部内に走行自在にはめ込んである。添付図面に示す実施形態では、戸４ａが主戸と副戸との２枚で構成してある。両縦枠３のうち戸当たり側となる縦枠３には戸当たり部３ａが設けてあり、この戸当たり部３ａの前面には上下方向に複数個の挟み金具４５が取付けてある。この挟み金具４５は一側部が縦枠３の前面部に固着され、他端部側がく字状に屈曲した挟持片４５ａとなっている。
【００１２】
開閉装置枠４の下レール枠２は図５に示すように、建物の梁のような構造材２２に取付けた下基材３４の上にブラケット１３を介して固着具３５により固着してある。ブラケット１３は図１に示すように断面コ字状をした長尺の連結板１９の両側部に連結板１９と一体に形成してあり、両側のブラケット１３間の長さは連結板１９により一定の長さに維持されている。各ブラケット１３の前端部にはそれぞれ挟持部１６と立ち上がり突片１８とが上方に向けて突出している。ここで、断面コ字状の連結板１９を下レール枠２の下面側に被嵌した状態で下レール枠２を固着具３５により下基材３４に固着するものであり、この場合、連結板１９が下レール枠２の所定位置に位置決めされた状態で同時に下基材３４に固着されるものである。そして、固着した状態では連結板１９の両側に設けたブラケット１３の前端部が下レール枠の前面側に位置することで、挟持部１６と立ち上がり突片１８とが下レール枠２の前面側の上方に設けられることになる。この挟持部１６の底面である下横片は下レール枠２の上面と略一致している。
【００１３】
図２に示すように、挟持部１６は上方に向けて突出した後縦片１５と前縦片１４とを近接対向して構成してあり、後縦片１５は前縦片１４よりも上方に長く突出してあり、後縦片１５と前縦片１４との下端部同士は細幅の下横片により一体化してある。
また、開閉装置枠４の上レール枠１は建物の壁下地材７に連結金具５１を介して取付けてある。ここで、図９の実施形態においては連結金具５１がアングル材５１ａとアングル材５１ａの下端部に設けた固定板５１ｂとで構成してあり、アングル材５１ａを壁下地材７に固着し、固定板５１ｂに上レール枠１を固着具により固着してある。
【００１４】
図３、図４、図５、図９に示すように、開閉装置枠４をエレベータ乗り場５の開口部６の後部に取付けた状態で、開閉装置枠４の横方向の一部が開口部６の隣りの壁下地材７の後面側に位置するようにしてあり、この開閉装置枠４の横方向の一部の開口部６の隣の壁下地材７の後面側に位置する部分が戸袋部８となっており、主戸と副戸とよりなる戸４ａを移動して戸袋部８内に収納した状態で開口部６が開放され、また、主戸と副戸とよりなる戸４ａを戸袋部８から引出して開口部６を閉じるようになっている。
【００１５】
開口部６には更に、図１に示すような門型をした開口枠１１が配設される。開口枠１１は、両側の外縦枠９と上枠３６とで門型に枠組みされ且つ外縦枠９の内面側に沿って額縁用縦枠１０を取付けて主体を構成してある。
外縦枠９は図２に示すように、前面片９ａの一端部から前後幅の長い長側片ｂａを後方に向けて突設すると共に前面片９ａの他端部から前後幅の短い短側片９ｃを後方に向けて突設して構成してある。また、額縁用縦枠１０は前片１０ａと側片１０ｂとのなすコーナ部分が傾斜片１０ｆとなり、側片１０ｂの後端部に後片１０ｃを突設し、更に、前片１０ａの端部に後方に向けて後向片１０ｄを突設して構成してあって、一側方及び後方が開口する形状となっている。
【００１６】
そして、図１、図２に示すように、上記の構成の額縁用縦枠１０の背面側において一側方及び後方が開口した額縁用縦枠１０の側端部と後端部とにわたって水平断面Ｌ字状をした取付け金具１２を上下方向に複数個架設してある。この水平断面Ｌ字状をした取付け金具１２の外縦枠９と対向する片１２ａと外縦枠９とを固着具３７により固着してある。したがって、こ取付け金具１２は背面側において一側方及び後方が開口した額縁用縦枠１０の保形の役目をすると共に額縁用縦枠１０と外縦枠９とを一体に連結するための部材としての役目をするものであって、いわば骨組材としての役目をしていると言える。ここで、取付け金具１２の片１２ａと外縦枠９とを固着具３７によって固着するに当たって、図２（ａ）に示すように、外縦枠９の長側片９ａに前後方向に複数の挿入孔３８を形成し、壁下地材７をベースとして構成される壁の厚みに応じて上記複数の挿入孔３８のうち任意の挿入孔３８を選択してねじ具よりなる固着具３７を挿入して片１２ａに設けた螺合孔３９にねじ具よりなる固着具を固着するするものである。これにより、現場における壁４９（壁下地材７の表面側に壁表面仕上げ材８を取付けて壁４９が構成される）の厚みに違いがあっても壁面と外縦枠９の前端面との間の寸法（チリ寸法）を一定にできる。添付図面に示す実施形態においては壁４９の壁面よりも外縦枠９の前端面が後方に一定寸法引き込んで位置している例を示しているが、壁４９の壁面よりも外縦枠９の前端面が前方に一定寸法突出したものであってもよい。
【００１７】
額縁用縦枠１０は外縦枠９よりも短いものであって、外縦枠９の下端部と額縁用縦枠１０の下端部とが同じレベルとなっているが、外縦枠９の上部が額縁用縦枠１０の上端部よりも上方に突出しているものである。額縁用縦枠１０の上端面部には上面板１０ｅが設けてある。外縦枠９の上部間には上枠３６が架設されるが、添付図面に示す実施形態においては、上枠３６が上枠材３６ａと外上枠材３６ｂとで構成してある。上枠材３６ａは両端部を両側の額縁用縦枠１０の上面板１０ｅの上面に載置してねじ具のような固着具により連結固着される。また、外上枠材３６ｂは外縦枠９の上端部間に架設されてねじ具のような固着具により連結固着される。
【００１８】
外縦枠９の上部間の上枠材３６ａと外上枠材３６ｂとの間には、制御盤４０が配設されて取付けられる。ここで図１０、図１１に示すように、制御盤４０の外殻を構成するケースの側面部と外縦枠９とにはそれぞれ開口部４１ａ、４１ｂが形成してあり、両開口部４１ａ、４１ｂが連通するように配置した状態で、Ｕ字状をした図１２に示すようなクリップ４２を両開口部４１ａ、４１ｂの開口縁部を挟持するようにはめ込んで連結し、更に、クリップ４２を貫通するように螺子具４３を挿入して固着することで、クリップ４２を介して制御盤４０を外縦枠９に位置決めした状態で固着してある。なお、上記制御盤４０は１階のエレベータ乗り場５における開口枠１１に取付けるものであり、他の階においては取付ける必要はなく、この場合には上枠材３６は一つのものを用いて両側の外縦枠９の上端部間に架設すると共に上枠材３６を額縁用縦枠１０の上端面部に載設するものである。
【００１９】
上記のような構成の門型をした開口枠１１をエレベータ乗り場５の開口部６の前部に配設して建て込むに当たっては次のようにして行う。
すなわち、門型の開口枠１１をエレベータ乗り場５の開口部６に位置させ、図５に示すように、門型の開口枠１１の両側の額縁用縦枠１０に設けた最下段の取付け金具１２の下レール枠２に沿った片１２ｂをそれぞれ挟持部１６に嵌め込み挟持すると共に両側の額縁用縦枠１０の後端部の後片１０ｃの下端部の内側に立ち上がり突片１８が差し込まれて面接して位置決めされる。この時、同時に一方の額縁用縦枠１０の後片１０ｃを、図７に示すように開閉装置枠４の縦枠３に設けた戸当たり部３ａに取付けた挟み金具４５の裏側に差し込んで挟み金具４５の挟持片４５ａと縦枠３の前面部とで挟持する（図６参照）。ここで、後片１０は断面Ｌ状をしているが、上記挟持片４５ａの裏側に差し込む部分は一部が切欠してあって平板状をしている。この状態で、他方の額縁用縦枠１０（つまり戸袋部８側の額縁用縦枠１０）に設けた取付け金具１２と戸袋部８側の壁下地材７の背面部とを図８に示すように、継手金具４４を用いて固着具により固着して連結するものである。また、開閉装置枠４の上レール枠１は建物の壁下地材７に取付けている連結金具５１に門型の開口枠１１の上部を固着具により取付けるものである。この場合、図９に示すように制御盤４０と連結金具５１の下端部の固定板５１ｂとを固着具により固着したり、あるいは上枠材３６と連結金具５１の下端部の固定板５１ｂとを固着具により固着したりするものである。
【００２０】
ところで、本発明においては、開口枠１１の両側の下端部を位置決めして支持するに当たって、従来例のように先端が自由端となった載置片上に載置するものでなく、ブラケット１３の前端部に前縦片１４と後縦片１５とを近接対向して突設して挟持部１６を形成すると共に、ブラケット１３の前端部の挟持部１６の隣りに立ち上がり突片１８を上方に向けて突設し、門型の開口枠１１の両側の額縁用縦枠１０に設けた最下段の取付け金具１２の下レール枠２に沿った片をそれぞれ挟持部１６に嵌め込み挟持すると共に両側の額縁用縦枠１０の後端部の下端部の内面側に立ち上がり突片１８を差し込んでいるので、挟持部１６、立ち上がり突片１８が従来例の載置片のように開口枠１１の荷重で撓むことなく、門型の開口枠１１の下端部を正確に位置に位置決め保持することができることになる。そして、門型の開口枠１１の両側下端部をそれぞれ挟持部１６と立ち上がり突片１８とで位置決め保持するので、門型の開口枠１１の両側下端部を位置決めした状態で確実且つ強固に保持できるものである。また、額縁用縦枠１０の下端部と、額縁用縦枠１０を保形し且つ額縁用縦枠１０を外縦枠９に連結するための骨材となる取付け金具１２の２箇所で保持されるので、門型の開口枠１１の両側下端部の位置決め保持がより強固で且つ確実なものとなるのである。
【００２１】
ここで、図１に示す実施形態においては、下レール枠２の開口部６の下基材１３との間に挟着されたブラケット１３を長尺の連結板１９の両側に形成してあるので、連結板１９を前述のように施工するのみで両側のブラケット１３間の長さが設計通りの一定寸法となるように施工できるものである。このため両側のブラケット１３において挟持して保持される門型の開口枠１１の両側下端部間の長さが一定となるように施工できることになる。
【００２２】
上記のようにして開口枠１１をエレベータ乗り場５の開口部６の前部に配設して開閉装置枠４の戸袋部８を除く前面側に配設して取付けた後、図３に示すように、エレベータ乗り場５の床には床仕上げ材４７が敷設され、また、壁下地材７の前面側、つまり、エレベータ乗り場５側には壁表面仕上げ材４８が取付けられて壁４９が構成されることになる。ここで、床仕上げ材４７の端部の一部が開口枠１１の両側下端面部の下面側に差し込んで取付けられるものであり、この場合、開口枠１１の下端部のレベルが上記のように差込みによって挟持されて所定位置に保持されているので、床仕上げ材４７が開口枠１１の両側下端面部の下面側に正確な位置関係で取付けられるものである。また、開口部において開閉装置枠４の下レール枠２の前端部と床仕上げ材４７の端部との間にできる隙間は図１に示すようなカバー材４６を取付けることで覆い隠されるものである。
【００２３】
【発明の効果】
本発明の請求項１記載の発明にあっては、上記のように額縁用縦枠の背面側において一側方及び後方が開口した額縁用縦枠の側端部と後端部とにわたって水平断面Ｌ字状をした取付け金具を上下方向に複数個架設し、この水平断面Ｌ字状をした取付け金具の外縦枠と対向する片と外縦枠とを固着し、下レール枠の開口部の下基材との間に挟着されたブラケットの前端部に前縦片と後縦片とを近接対向して突設して挟持部を形成すると共に、ブラケットの前端部の挟持部の隣りに立ち上がり突片を上方に向けて突設し、門型の開口枠の両側の額縁用縦枠に設けた最下段の取付け金具の下レール枠に沿った片をそれぞれ挟持部に嵌め込み挟持すると共に両側の額縁用縦枠の後端部の下端部の内面に立ち上がり突片を差し込むので、門型の開口枠の両側下端部をそれぞれ挟持部と立ち上がり突片とで保持できて、門型の開口枠の両側下端部を位置決めした状態で簡単且つ確実に保持できるものであり、また後片と前片とを上方に突出して挟持部を構成し、立ち上がり突片を上方に突出してあるので、下端部が自由端となった門型の開口枠の両側下端部がそれぞれ２つの保持手段により保持されることになり、より正確に且つ強固に保持ができるものであり、また、額縁用縦枠の下端部と、額縁用縦枠を保形し且つ額縁用縦枠を外縦枠に連結するための骨材となる取付け金具の２箇所が保持されることとなって、門型の開口枠の両側下端部の位置決め保持がよりいっそう確実となるものである。
【００２４】
また、請求項２記載の発明にあっては、上記請求項１記載の発明の効果に加えて、挟持部の後縦片を前縦片よりも上方に長く突出してあるので、後縦片をガイドとして挟持部に取付け金具の一片を簡単に差込んで挟持させることができて、門型の開口枠の下端部の挟持部への差込みが容易に行えるものである。
また、請求項３記載の発明にあっては、上記請求項１又は請求項２記載の発明の効果に加えて、下レール枠の開口部の下基材との間に挟着されたブラケットを長尺の連結板の両側に形成してあるので、両側のブラケット間の長さを設計通りの一定寸法とすることができて、両側のブラケットにおいて挟持して保持される下端部が自由端部となった門型の開口枠の両側下端部間の長さが一定となるように施工することができるものである。

BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for an opening frame of an elevator hall.
[0002]
[Prior art]
An opening / closing device frame having a door detachably attached to the rear portion of the opening is attached to the opening of the elevator platform. This switchgear frame has an upper rail frame, a lower rail frame, and vertical frames on both sides, and a door is movably installed in the frame. This switchgear frame is attached to the rear of the opening of the elevator platform. In this case, a part of the opening / closing device frame in the lateral direction is located on the rear surface side of the wall base material adjacent to the opening to form a door pocket. That is, when the door attached to the opening / closing device frame is closed, the opening of the elevator hall is closed, and when the door is moved and positioned in the door pocket, the opening of the elevator hall is opened. .
[0003]
Then, a gate-shaped opening frame is arranged at the opening of the elevator hall, and is disposed and attached to the front side excluding the door pocket portion of the switchgear frame, so that the periphery of the opening is configured.
The lower rail frame 2 of the switchgear frame 4 is attached to a lower base material 34 attached to a structural material 22 such as a building beam as shown in FIG. And the mounting piece 60 which the front-end | tip became the free end protruded from this lower rail frame 2 toward the front. As shown in FIG. 15, the gate-shaped opening frame 11 is mounted on a mounting piece 60 having a free end at the front end protruding from the front surface side of the lower rail frame 2 of the switchgear frame 4. The positioning convex portion 61 provided on the placement piece 60 is locked in the locking hole 62 provided in the lower end surface portion of the opening frame 11 so that the lower end portion of the opening frame 11 is positioned and held.
[0004]
However, the lower end portion of the opening frame 11 is attached as shown in FIG. 16 so as to be substantially flush with the upper surface of the lower rail frame 2. This is because the floor material used as the floor surface has not yet been constructed on the floor of the elevator hall at the time of the elevator construction, and the floor material on the floor foundation of the elevator hall 5 after the elevator construction is completed (that is, after the opening frame 11 is installed). The floor material is constructed so as to be inserted into the lower surface side of the opening frame 11 in the opening frame 11 portion, and therefore the lower end portion of the opening frame 11 is substantially the same as the upper surface of the floor material. It is built so as to be substantially flush with the upper surface of the lower rail frame 2 that is flush.
[0005]
Thus, when the opening frame 11 is mounted on the mounting piece 60 that protrudes forward from the front side of the lower rail frame of the opening / closing device frame 4, the mounting piece 60 bends downward so that the lower end of the opening frame 11 is accurately positioned. Since it cannot be positioned and held so as to have a high height relationship, it is difficult to align the position, and the positioning protrusion 61 and the locking hole 62 can be locked by bending the mounting piece 60 downward. There is a problem that the lower end portion of the opening frame 11 cannot be held due to being detached.
[0006]
[Problems to be solved by the invention]
The present invention has been invented in view of the above-described problems of the conventional example, and can accurately and firmly position and hold the lower end portions on both sides of a gate-shaped opening frame with a simple configuration, and the lower end portion of the opening frame. Can be inserted easily to hold the frame, and can be accurately positioned and held so that the dimension between the lower ends on both sides, which are the free ends of the double-portion opening frame, is an accurate dimension. It is an object of the present invention to provide a structure for attaching an opening frame of an elevator hall.
