Description

【０００１】
【発明の属する技術分野】
本発明は、外周側部から水平方向に張り出した床部と、該床部の先端から立上がる立上部とを有する構造物本体に、前記立上部を基礎として組足場を設置する際に用いる足場支持治具に関する。
【０００２】
【従来の技術】
例えば、バルコニを有するマンション等の構造物本体に、バルコニ等を利用して公知のビティ足場や単管足場等の組足場を、前記構造物本体の外側に沿って複数階層ごとに設置するための足場支持治具が提案されている（例えば、特許文献１参照）。
【０００３】
この足場支持治具では、バルコニの立上部の上端面に載置される載置部から下方に向けて突出するように固定された第一挟接体と、前記載置部に移動可能に嵌合する位置調整保持手段に前記第一挟接体と対向するように固定された第二挟接体を有し、前記第一挟接体の下端に、組足場を支持する支持部材を固定し、該支持部材の先端部に複数の支持脚接合部材を一定の間隔で固定した構成になっている。

【発明が解決しようとする課題】
例えば、屋上階の外周に、屋上の床面を形成するスラブの上方に前記支持部材を突出させて、防水工事用の足場を構築する場合、位置調整保持手段側に支持脚を立設させ、手すり等を設けることが要求される。しかし、前記足場支持治具では、位置調整保持手段側に支持脚を配置することができない。このため、屋上階の防水工事等では前記足場支持治具を用いることなく単管足場を構築するなど、足場支持治具の利用範囲が限定されていた。
【０００６】
上記の事情に鑑み、本発明は、支持脚接合部材の取付け位置を移動可能とし、より広い範囲の作業目的に適合させて利用できる足場支持治具を提供することを目的とする。
【０００７】
【課題を解決するための手段】
上記の目的を達成するため、請求項１に係る発明は、外周側部から水平方向に張り出した床部と、該床部の先端から上方に立上る立上部とを有する構造物本体に、前記立上部を基礎として組足場を組み立てるために使用する足場支持治具であって、
前記足場支持治具（１５、３０、４０、５０）は、前記立上部（３ｅ、５ｂ）に係着する係着部（１５ｂ、３０ｂ、４０ｂ、５０ｂ）と、前記組足場（７）を支持する支持部（１５ａ、３０ａ、４０ａ、５０ａ）を有し、

該スライダ（１７、３２）は、前記支持部（１５ａ、３０ａ、４０ａ、５０ａ）及び前記係着部（１５ｂ、３０ｂ、４０ｂ、５０ｂ）に摺動自在に嵌合されるように構成され、
前記支持脚接合部材（２０）は、前記スライダ（１７、３２）を介して前記支持部（１５ａ、３０ａ、４０ａ、５０ａ）又は前記係着部（１５ｂ、３０ｂ、４０ｂ、５０ｂ）に固定される、ことを特徴とする。
【０００９】
さらに、請求項３に係る発明は、請求項１又は２に記載の発明において、前記係着部（１５ｂ、３０ｂ、４０ｂ、５０ｂ）の前記載置部（１６ｆ）が、前記支持脚接合部材（２０）を着脱固定自在とするように構成された、ことを特徴とする。
【００１０】
また、請求項４に係る発明は、請求項１乃至３のいずれか 1 項に記載の発明において、前記支持脚接合部材（２０）は、支持脚（９）の接合部にねじ（２０ａ）が形成されている。

【００１４】
なお、括弧内の符号等は、図面において対応する要素を示す便宜的なものであり、従って、本記述は図面上の記載に限定拘束されるものではない。
【００１５】
【発明の効果】
以上述べたように、請求項１〜３に記載の発明によると、前記支持部及び前記係着部が前記支持脚接合部材を着脱固定自在とするように構成されているので、支持脚接合部材を必要に応じて支持部もしくは係着部に取付けることができ、多様な作業に対応することができる。例えば、屋上の防水工事等においては、図４又は図５に示すように、作業態様に応じて支持部を屋上の内周又は外周側に装着し、任意の位置に支持脚接合部材を設置することができる。従って、より広い範囲の作業目的に対応させることができ、工事の作業性を向上させることができる。
【００１６】

【００１７】
また、請求項５記載の発明によると、第１の挟接体と第２の挟接体とをねじ手段により接続しているので、第１挟接体と第２挟接体との間隔を任意に設定することができ、請求項１記載の発明の効果に加え、バルコニの立上部の厚さの変化に拘わらず、常に最適な状態で取付けることができる。
【００１８】
また、請求項６記載の発明によると、クランプ部材により挟接体間を固定するようにしたので、請求項１記載の発明の効果に加え、足場支持治具の操作を容易にすることができる。
【００１９】
また、請求項７記載の発明によると、足場支持治具を、立上部に固定する係着部と、組足場を支持する支持部とを接合部を介して着脱自在となるように構成したので、請求項１記載の発明の効果に加え、一体の足場支持治具に比べて取り扱う重量を軽減することができ、足場支持治具の取り扱いを容易にすることができる。また、係着部と支持部の大型化、高強度化を図り、より重荷重を支えることを可能にした足場支持治具を得ることができ、一階層に取付けた足場支持治具からより高い階層まで組足場を伸ばすことができる。
【００２０】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。図１は、本発明による足場支持治具を用いた組足場の設置状態を示す側面図である。
【００２１】
同図において、地盤１に鉄筋コンクリート等で構築された基礎構築物２の上に、鉄筋コンクリートで構造物本体３が構築されている。この構造物本体３は、梁、柱構造をなす複数の柱３ａと梁３ｂを有し、これら柱３ａと梁３ｂには、複数のスラブ３ｃが一体に層状に構築され、各階の床や天井を形成している。
【００２２】
前記構造物本体３の外周部３ｄ（図１の紙面左側）には、鉄筋コンクリートで複数のバルコニ５が構造物本体３と一体に形成されている。このバルコニ５は、前記各梁３ｂから水平方向（矢印Ａ方向）に突出し、上下層状に形成された床部５ａと、この床部５ａの先端側（矢印Ａ方向の端部）に、床部５ａと一体に形成され、上方に向けて立上る壁状の立上部５ｂが設けられている。なお、この立上部５ｂの高さは、バルコニ５の床部５ａに立つ人の落下を防止するのに十分な高さを持っている。
【００２３】
また、前記構造物本体３の屋上階には、屋上の周囲を囲う立上部３ｅと、最上階のバルコニ５の上方に突出する庇５ｆが形成されている。
【００２４】
図１に示す構造物本体３の例では、バルコニ５が設けられているのは、２階以上の階層になっており、１階の位置にはバルコニ５が設けられていない。この構造物本体３の場合、１階（或いは１階及び地階）部分は、駐車場空間６として形成されており、構造物本体３の壁には外部と駐車場空間６を連通する車出入口６ａが形成されている。なお、構造物本体３の１階部分も住戸とする場合には、１階部分にもバルコニ５を配置してもよい。
【００２５】
２階部分のバルコニ５の立上部５ｂには、本発明による足場支持治具１５（又は３０、又は４０、又は５０）が設置されている。この足場支持治具１５（又は３０、又は４０、又は５０）上には、２階から屋上階まで５階層分の組足場７が構築され、その支持脚９は、適宜位置で壁つなぎ１０により構造物本体３（バルコニ５の立上部５ｂ、庇３ｆ）に繋がれている。また、足場板１１は、ブラケット１２を介して支持脚９の適宜位置に支持されているほか、足場支持治具１５（又は３０、又は４０、又は５０）の上にも配置されている。なお、組足場７の外側には、メッシュシート１３が配置されている。
【００２６】
図２乃至図５は、本発明による足場支持治具の第１の実施の形態を示すもので、図２は、本発明による足場支持治具の側面図、図３は、図２の平面図、図４は、図１の足場支持治具を屋上階から外側に向けて取り付けた状態を示す側面図、図５は、図１の足場支持治具を屋上階から内側に向けて取り付けた状態を示す側面図である。
【００２７】
同図において、足場支持治具１５は、組足場７を支持する支持部１５ａと、バルコニ５の立上部５ｂや、構造物本体３の屋上階の立上部３ｅに取付けるための係着部１５ｂとを有している。
【００２８】
前記支持部１５ａを構成する支持部材１６は、断面が矩形の筒状部材で形成されている。この支持部材１６の矢印Ａ方向の端部には、その側面１６ｂを紙面の前後方向に貫通する複数の貫通穴１６ｄが所定の間隔で形成され、矢印Ｂ方向の端部には、その側面を紙面の前後方向に貫通する複数の貫通穴１６ｅが所定の間隔で形成されている。
【００２９】
前記支持部材１６に摺動可能に嵌合するスライダ１７には、前記貫通穴１６ｄと連通する貫通穴（図示せず）が形成されている。そして、該スライダ１７は、その貫通穴と前記支持部材１６の貫通穴１６ｄを貫通するボルト１９ａと、該ボルト１９ａに螺合するナット１９ｂで構成される固定手段１９によって所要の位置に固定される。
【００３０】
前記スライダ１７には、前記支持部材１６の上面１６ａから上方に向けて突出するように、支持脚接合部材２０が固定されている。この支持脚接合部材２０の上端部には、ねじ２０ａが形成されている。
【００３１】
前記支持部材１６の下面１６ｃの矢印Ｂ方向の端部には、断面が矩形の筒状部材で形成された第一挟接体２１が固定されている。そして、支持部材１６の第一挟接体２１から矢印Ｂ方向に突出する部分は、バルコニ（図１参照）５の立上部５ｂの上端面５ｃに載置される載置部１６ｆとなる。前記支持部材１６の下面１６ｃと第一挟接体２１の矢印Ａ方向の側面との間には、断面が矩形の筒状部材で形成された補強部材２１ｂが接合されている。なお、第一挟接体２１の矢印Ｂ方向の側面には、スペーサ２１ａが固定されている。
【００３２】
前記第一挟接体２１は、その断面寸法が、前記支持部材１６の断面寸法と同一かそれより小さい部材で形成されている。また、前記補強部材２１ｂは、その断面寸法が、前記第一挟接体２１の断面寸法と同一かそれより小さい部材で形成されている。なお、補強部材２１ｂの接合位置は、支持部材１６の上面１６ａから上方へ突出せず、かつ第一挟接体２１の矢印Ｂ方向の側面から矢印Ｂ方向へ突出しない限り、支持部材１６の側面１６ｂと第一挟接体２１の紙面前後方向の側面であってもよい。
【００３３】
調整部材２２は、前記支持部材１６の内部に摺動自在に装着し得る大きさの断面が矩形の筒状部材で形成されている。この調整部材２２の矢印Ａ方向の端部には、その側面２２ｂを紙面の前後方向に貫通し前記支持部材１６の貫通穴１６ｅと連通する複数の貫通穴２２ｄが所定の間隔で形成され、中央部から矢印Ｂ方向の端部に向けて、その側面２２ｂを紙面の前後方向に貫通する複数の貫通穴２２ｅが所定の間隔で形成されている。
【００３４】
なお、前記調整部材２２の矢印Ａ方向の一端には、内周に補強部材２２ｆが固定され、外周にスペーサ２２ｇが固定されている。また、貫通穴２２ｅが形成された部分には、その内周及び外周に補強部材２２ｈが配置され、調整部材２２の強度の低下を補っている。
【００３５】
前記調整部材２２の矢印Ｂ方向の端部には、該調整部材２２の断面寸法より幅の広い断面が溝形の部材で形成された第二挟接体２３が固定されている。なお、調整部材２２と第二挟接体２３の接合部は、補強部材２３ａで補強されている。
【００３６】
前記第二挟接体２３の第一挟接体２１との対向面には、複数（図２では２個）の貫通穴（図示せず）が形成されている。これら貫通穴と連通するように第二挟接体２３に固定されたナット２５ａに螺合するボルト２５ｂの矢印Ａ方向の端部には、パッド２５ｃが揺動及び回転自在に支持されている。
【００３７】
なお、前記調整部材２２は、前記支持部材１６の貫通穴１６ｅと、該貫通穴１６ｅと連通する貫通穴２２ｄを貫通するボルト２６ａと、該ボルト２６ａに螺合するナット２６ｂで構成される結合手段２６により結合される。そして、前記第一挟接体２１、支持部材１６、調整部材２２及び第二挟接体２３で係着部１５ｂを構成している。
【００３８】
このような構成で、予め、支持脚接合部材２０を支持部材１６の所要の位置に配置して、固定手段１９のボルト１９ａ、ナット１９ｂを締めつけて固定する。
【００３９】
構造物本体３（図１参照）が二階層以上構築されている状態で、構築されているバルコニ５の立上部５ｂの上端面５ｃに、支持部材１６の載置部１６ｆが接触し、立上部５ｂの矢印Ａ方向の側面に第一挟接体２１のスペーサ２１ａが接触するように、足場支持治具１５を載置する。
【００４０】
支持部材１６と調整部材２２の結合部から結合手段２６のボルト２６ａを抜き取り、調整部材２２を矢印Ａ方向に、第二挟接体２３が立上部５ｂの内側面に対し所要の位置（例えば、二点鎖線で示す位置）まで移動させる。そして、互いに連通する支持部材１６の貫通穴１６ｅと調整部材２２の貫通穴２２ｄの軸心を整合させ、貫通穴１６ｅ、２２ｄにボルト２６ａを挿入し、ナット２６ｂを締めて支持部材１６と調整部材２２を結合する。
【００４１】
この状態で、第二挟接体２３に支持されたボルト２５ｂを回して、パッド２５ｃを立上部５ｂの内側面に押付ける。このとき、パッド２５ｃは、ボルト２５ｂに対して揺動及び回転自在であるので、立上部５ｂの内側面に沿って接触し、立上部５ｂの内側面を傷つけることはない。
【００４２】
このようにして、複数の足場支持治具１５をバルコニ５（図１参照）の立上部５ｂに固定した後、複数の支持部材１６に亘って足場板１１を載置する。なお、足場板１１は、図示しない係止部材により支持部材１６に係止される。この際、支持部材１６の上面１６ａには、図２に示すように、補強部材２１ｂ等が突出していないので、支持部材１６の上面１６ａには、足場板１１を載置するのに十分な足場板載置領域ＡＲＡが形成され、足場板１１の設置を円滑に行なうことができる。そして、この足場板１１上に登って支持脚９を支持脚接合部材２０に螺合させ接合する。
【００４３】
以下、通常の組足場７の構築作業と同様の作業により、足場支持治具１５上に組足場７（図１参照）を構築することができる。
【００４４】
図４に示すように、構造物本体３の屋上階がその外周部３ｄから矢印Ｂ方向に突出し、その外周部に立上部３ｅが形成され、さらにその外側（矢印Ｂ方向）に組足場７を構築する場合がある。
【００４５】
このような場合にも、前記図２に示すバルコニ５に取付けた場合と同様に、支持部材１６が構造物本体３の外側（矢印Ｂ方向）に突出するように、屋上階のスラブ３ｃに形成された立上部３ｅに固定し、支持脚接合部材２０に支持脚９を接合し、手すり９ａを取付けて組足場７を構築する。
【００４６】
また、図５に示すように、構造物本体３の屋上階の防水工事等で、屋上階の立上部３ｅの内側（矢印Ａ方向）に足場が必要な場合がある。
【００４７】
このような場合には、支持部材１６から外した支持脚接合部材２０を、調整部材２２の所要の位置に固定した状態で、支持部材１６が屋上階のスラブ５ｃの上方（矢印Ａ方向）に突出するように立上部３ｅに載置し固定する。そして、支持部材１６上に足場板１１を載置するとともに、調整部材２２に固定した支持脚接合部材２０に支持脚９を接合し、手すり９ａを取付けて組足場７を構築する。
【００４８】
前記のように、支持脚接合部材２０を支持部材１６（支持部１５ａ）側だけでなく、調整部材２２（係着部１５ｂ）側に取付けることができるので、従来と異なる態様で使用することができ、足場支持治具１５の利用範囲を広げることができる。
【００４９】
図６及び図７は、本発明による足場支持治具の第２の実施の形態を示すもので、図６は本発明による足場支持治具の側面図、図７は、図６の平面図である。
【００５０】
同図において、図２、図３と同じものは同じ符号をつけて示し、説明を省略する。足場支持治具３０は、組足場７（図１参照）を支持する支持部３０ａと、足場支持治具３０をバルコニ５（図１参照）の立上部５ｂに取付けるための係着部３０ｂとを有している。
【００５１】
前記支持部３０ａを構成する支持部材３１は、断面が矩形の筒状部材で形成されている。この支持部材３１の矢印Ａ方向の一端部には、支持部材３１に摺動自在に外嵌するスライダ３２が配置され、このスライダ３２の上面３２ａに、支持脚接合部材２０が上方に向けて突出するように固定されている。
【００５２】
なお、前記スライダ３２は、スライダ３２の下面３２ｂに固定されたナット３２ｃに螺合するボルト３２ｄで支持部材３１の任意の位置に固定される。即ち、ボルト３２ｄは、固定手段を構成する。また、支持部材３１の矢印Ａ方向の端部に形成された貫通穴（図示せず）を貫通するボルト３３ａと、このボルト３３ａに螺合するナット３３ｂからなるストッパ３３で支持部材３１から脱落するのを防止されている。
【００５３】
前記支持部材３１の下面３１ｃの矢印Ｂ方向の端部には、断面が矩形の筒状部材で形成された第一挟接体２１が固定されている。そして、前記支持部材３１の下面３１ｃと第１挟接体２１の矢印Ａ方向の側面との間には、断面が矩形の筒状部材で形成された補強部材２１ｂが固定されている。なお、補強部材２１ｂは、支持部材３１の上面３１ａから上方に突出しない限り、支持部材３１の側面３１ｂに固定するようにしてもよい。
【００５４】
ブラケット３５は、バルコニ５（図１参照）の立上部５ｂの上端面５ｃに載置される載置部３５ａと、この載置部３５ａの紙面前後方向の両端から、前記支持部材３１の両側面３１ｂに接触する幅で上方に向けて形成された立上部３５ｂと、この立上部３５ｂの矢印Ａ方向の端部から下方に向けて前記第一挟接体２１の側面に接触するように形成された固定部３５ｃとを有している。そして、前記ブラケット３５は、前記載置部３５ａが前記支持部材３１の下面３１ｃと同じ高さになるようにボルト３５ｄと、このボルト３５ｄに螺合するナット３５ｅで前記第一挟接体２１に着脱自在に固定されている。
【００５５】
前記ブラケット３５の載置部３５ａの中央部には、所要の高さになるようにスペーサ３６ａを介してその軸心が矢印Ａ−Ｂ方向と平行になるようにナット３６が固定されている。
【００５６】
前記第一挟接体２１と第二挟接体２３とを相対移動自在に接合し、前記バルコニ５（図１参照）の立上部５ｂの厚さに応じて、前記第一挟接体２１と第二挟接体２３の間隔を調整するための調整部材３７は、前記支持部材３１の内部に摺動自在に装着し得る大きさの断面が矩形の筒状部材で形成され、その底面３７ａには、矢印Ａ方向の端部から所要の位置まで前記スペーサ３６ａと摺動自在に嵌合する溝３７ｂが形成されている。
【００５７】
前記調整部材３７の矢印Ｂ方向の端部には、調整部材３７の断面寸法と同じ幅の、断面が溝形の部材で形成された第二挟接体２３が固定されている。なお、調整部材３７と第二挟接体２３の接合部は、補強部材２３ｂで補強されている。そして、ブラケット３５（の載置部３５ａ）、第一挟接体２１、調整部材３７及び第二挟接体２３で、係着部３０ｂが構成される。
【００５８】
前記第二挟接体２３に形成された貫通穴（図示せず）を移動自在に貫通するねじ軸３９の矢印Ａ方向の一端は、前記ナット３６に螺合している。また、このねじ軸３９の頭部３９ａは、６角形に形成され、スパナ等でねじ軸３９を回転させられるようになっている。また、ねじ軸３９の首部には、前記第二挟接体２３の貫通穴の周囲に当接する座３９ｂが装着され、第二挟接体２３の矢印Ｂ方向への移動を規制している。
【００５９】
このような構成で、予め、スライダ３２を所要の位置へ移動させボルト３２ｄを締めて、支持脚接合部材２０を支持部材３１に固定する。
【００６０】
構造物本体３（図１参照）が二階層以上構築されている状態で、構築されているバルコニ５の立上部５ｂの上端面５ｃに、ブラケット３５の載置部３５ａが接触するように、即ち、第一挟接体２１が立上部５ｂの外側面（矢印Ａ方向の側面）と対向し、第二挟接体２３が立上部５ｂの内側面（矢印Ｂ方向の側面）と対向するように足場支持治具３０を立上部５ｂの上端面５ｃに載置する。
【００６１】
そして、第一挟接体２１を立上部５ｂの外側面に接触させ、ねじ軸３９を回転させ、第二挟接体２３を立上部５ｂの内側面に対し所要の位置（例えば、二点鎖線で示す位置）まで移動させる。この状態で、ボルト２５ｂを回し、パッド２５ｃを所要の力で立上部５ｂの内側面に押しつける。このとき、パッド２５ｃは、ボルト２５ａに対し揺動及び回転自在であるので、立上部５ｂの内側面に倣って接触し内側面を傷つけることはない。
【００６２】
このとき、前記したように、調整部材３７は、前記支持部材３１の内部に摺動自在に装着し得る大きさの断面が矩形の筒状部材で形成されているので、支持部材３１の上面３１ａと係着部３０ｂを構成する調整部材３７の上面３７ｃとは、ほぼ同じ（支持部材３１の上面３１ａが調整部材３７の上面３７ｃより若干高くなる）高さになっている。
【００６３】
このようにして、複数の足場支持治具３０をバルコニ５（図１参照）の立上部５ｂに固定した後、複数の支持部材３１に亘って足場板１１を載置する。なお、足場板１１は、図示しない係止部材により支持部材３１に係止される。この際、支持部材３１の上面３１ａには、図６に示すように、補強部材２１ｂなどが突出していないので、支持部材３１の上面３１ａには、足場板１１を載置するのに十分な足場板載置領域ＡＲＡが形成され、足場板１１の設置を円滑に行なうことができる。そして、この足場板１１の上に登って支持脚９を支持脚接合部材２０に螺合させ接合する。
【００６４】
以下、通常の組足場７の構築作業と同様の作業により、足場支持治具３０上に組足場７（図１参照）を構築することができる。
【００６５】
なお、上記の実施形態においては、前記ナット３６の破損等に備え、ナット３６の交換を容易にするため、ブラケット３５を第一挟接体２１にボルト３５ｄとナット３５ｅで固定したものについて説明したが、ナット３６の交換が必要ない場合には、ブラケット３５を第一挟接体２１や支持部材３１に溶接等で固定するようにしてもよい。また、ブラケット３５の固定部３５ｃをなくし、立上部３５ｂを支持部材３１に固定するようにしてもよい。
