Description

【０００１】
【発明の属する技術分野】
本発明は、簡単な操作で確実に棒体を抱持固定できる棒体抱持金具及び足場形成方法に関するものである。
【０００２】
【従来の技術及び発明が解決しようとする課題】
工事現場などの危険地帯を区画し、この危険地帯に人や自転車などが侵入することを防止するため、２つ以上の下方が広がっている形状のバリケード体を並べ、この並列バリケード体を単管などの長い棒体で連結してバリケードを形成している。
【０００３】
ところで、バリケード体と棒体とを連結するためには、従来においては、ロープやワイヤーなどでバリケード体に棒体を縛り付ける方法や、ボルトナットによる締め付け作用を用いて棒体抱持体とバリケード体との間に棒体を抱持する方法が採用されていたが、いずれの方法も作業時間が掛かり、バリケードの組み立て作業を厄介なものにしている。更に、作業時間が掛かることによって人件費もかかってしまう。
【０００４】
一方、複数の棒体を交叉や平行状態に連結して足場を形成する場合には、１人が棒体を支持し、もう１人が足場用棒体抱持金具で棒体を固定するという作業形態が採用されている。これは、棒体同志を連結する足場用棒体抱持金具の操作が困難である為（安全の為に棒体を確実に抱持固定する必要があるため、必然的にボルト・ナットの回動操作等厄介な作業が必要となる。）、１人ではどうしても棒体を支持しながら足場用棒体抱持金具を操作するということができないためである。従って、この方法では人件費が２人分かかるという問題点がある。
【０００５】
更に、複数の棒体を連結して雪囲い等の骨組みを作る際には従来からロープやワイヤーなどで棒体を縛り付ける方法が採用されていたが、この場合も作業時間が掛かってしまう上、高所で作業する場合に作業に時間が掛かるようではそれだけ作業の危険性が高まることになり、問題であった。
【０００６】
また、足場を形成する際に使用される棒体抱持金具等、特に高い安全性が要求される棒体抱持金具には、棒体を抱持する状態を強固に維持する構成が要求されている。
【０００７】
本発明は、上記問題点を解決するもので、棒体を確実且つ極めて簡単な操作でスムーズに着脱することができ、しかも棒体を極めて強固に抱持することができる極めて実用性，作業性に秀れた棒体抱持金具及び足場形成方法を提供することを目的としている。
【０００８】
【課題を解決するための手段】
添付図面を参照して本発明の要旨を説明する。
【０００９】
棒体支承部１を設けた基体２に抱持半体３を設けて前記棒体支承部１に当接せしめた棒体４に前記抱持半体３を被嵌して棒体４を抱持固定する棒体抱持金具Ａであって、前記基体２の一端に前記抱持半体３の基端を枢着し、この抱持半体３の先端に係止体５を設け、基体２の他端に軸杆18を横設し、ストッパー操作体７を設け、このストッパー操作体７に長孔19を設け、この長孔19に前記軸杆18を嵌挿することでストッパー操作体７を基体２の他端に枢着し、このストッパー操作体７に前記係止体５に係止可能な係止部８を設け、このストッパー操作体７を回動操作し且つ軸杆18に対してストッパー操作体７を上方にスライド移動することで前記基体２の他端からの突出量を大きくした際、前記係止部８を前記係止体５に係脱自在に係止できるように構成し、このストッパー操作体７を前記係止体５に前記係止部８を係止した状態を保持した状態で回動操作し且つ軸杆18に対してストッパー操作体７を下方にスライド移動することで前記基体２の他端部分にこのストッパー操作体７を添設状態に回動配設し得るように構成して、前記棒体４を前記基体２の棒体支承部１と抱持半体３とで抱持した際、このストッパー操作体７を基体２の他端部分に添設状態に回動配設し且つこのストッパー操作体７の回動によりストッパー操作体７が軸杆18に対してスライド移動して前記軸杆18が前記長孔19の一端に設けた軸杆係止部20に係止することで前記係止部８が前記係止体５から係脱不能となり棒体４が抱持固定され得るように構成し、前記棒体４が抱持固定された状態において、前記ストッパー操作体７の長孔 19 から露出する基体２にピン体 23 を挿入するための挿入孔 24 を設け、この挿入孔 24 に前記ピン体 23 を挿入することで前記ストッパー操作体７の回動及びスライドを防止できるように構成したことを特徴とする棒体抱持金具に係るものである。
【００１０】
また、前記長孔19に乗越部21を設け、前記ストッパー操作体７を前記基体２の他端部分に添設状態に回動配設し且つこのストッパー操作体７の回動によりストッパー操作体７が軸杆18に対してスライド移動して前記軸杆18が前記長孔19の一端に設けた前記軸杆係止部20に係止する際、この乗越部21を前記軸杆18が乗り越えて前記軸杆係止部20に係止するように構成したことを特徴とする請求項１記載の棒体抱持金具に係るものである。
【００１１】
また、前記長孔19を途中で屈曲する長孔19に構成し、この屈曲部を前記乗越部21に設定したことを特徴とする請求項１記載の棒体抱持金具に係るものである。
【００１２】
また、前記係止体５を舌片状に設け、前記係止部８をこの舌片状の係止体５に被嵌する形状に設け、この舌片状の係止体５の上向き度合いを上下調整することで前記基体２の棒体支承部１と抱持半体３とで前記棒体４を抱持する力を増減する抱持力増減機構22を有していることを特徴とする請求項１〜３のいずれか１項に記載の棒体抱持金具に係るものである。
【００１３】
また、前記基体２に連結部12を設けて請求項１〜４のいずれか１項に記載の棒体抱持金具Ａを前記連結部12で連結するとともにこの連結された棒体抱持金具Ａ・Ａ同志が回動自在及び回動不能になるように構成し、棒体４を交叉若しくは平行に連結して足場を形成する際、下記ａ及びｂの作業を連続的に行うことで足場を形成していくことを特徴とする足場形成方法に係るものである。
記
ａ２本以上の棒体４を交叉若しくは平行状態とし、この棒体４同志を前記２つ以上連結された棒体抱持金具Ａ・Ａで一旦仮連結する。
ｂ前記仮連結された棒体４同志を公知の足場用棒体抱持金具で連結し、その後、棒体４から前記２つ以上連結された棒体抱持金具Ａ・Ａを取り外す。
【００１４】
【発明の実施の形態】
好適と考える本発明の実施の形態（発明をどのように実施するか）を、図面に基づいてその作用効果を示して説明する。
【００１５】
棒体抱持金具Ａに棒体４を固定する際、先ず、棒体４を基体２の棒体支承部１に当接し、続いて、基体２の一端に枢着した抱持半体３を回動操作して前記棒体支承部１に載置した棒体４に被嵌する。
【００１６】
続いて、基体２の他端に枢着したストッパー操作体７を回動操作し、且つ、このストッパー操作体７を軸杆18に対して上方にスライド移動せしめて基体２の他端からの突出量を大きくし（この状態では、軸杆18が長孔19の下部側に位置することになる。）、このストッパー操作体７の係止部８を前記抱持半体３に設けた係止体５に係脱自在に係止できるようにする。
【００１７】
続いて、係止部８を係止体５に係止した状態を保持した状態でストッパー操作体７を基体２の他端部分に添設状態となるように回動操作し、且つ、このストッパー操作体７を軸杆18に沿って下方にスライド移動せしめて基体２の他端からの突出量を小さくし（この状態では、軸杆18が長孔19の上部側に位置することになる。）、更に、ストッパー操作体７を基体２の他端部分により一層添設させると、軸杆18が長孔19に設けられた軸杆係止部20に係止し、この係止が解除されない限り、前記ストッパー操作体７の軸杆18に対するスライド移動及び回動が不能となる。
【００１８】
この状態においては、前記ストッパー操作体７の突出量の減少により、係止部８が係止体５を押圧し、この係止体５に連設されている抱持半体３と基体２の棒体支承部１とで棒体４を抱持する。
【００１９】
即ち、棒体４は抱持半体３やストッパー操作体７の回動操作やストッパー操作体７のスライド移動という簡単な操作によって確実に棒体抱持金具Ａに抱持固定されることになる。
【００２０】
更に、ストッパー操作体７の長孔 19 から露出した基体２に形成された挿入孔 24 に対し、ピン体 23 を挿入配設することでストッパー操作体７の回動及びスライドが前記ピン体 23 によって阻止される。
【００２１】
即ち、挿入孔 24 に挿入配設されたピン体 23 によってストッパー操作体７の回動及びスライドを阻止することで、棒体４は棒体支承部１と抱持半体３とによって一層確実に棒体抱持金具Ａに抱持固定されることになる。
【００２２】
また、棒体抱持金具Ａから棒体４を取り外す際には、軸杆18に対するストッパー操作体７の回動操作により、軸杆18と軸杆係止部20との係止を解除し、更に、このストッパー操作体７を回動操作し、且つ、軸杆18に対してストッパー操作体７を上方にスライド移動することで、ストッパー操作体７基体２の他端からの突出量を大きくして係止部８を係止体５から係脱し、更に、この係止部８と係止体５との係止解除により回動自在になった抱持半体３を回動し、棒体支承部１から棒体４を取り外す。
【００２３】
【実施例】
本発明の具体的な実施例について図面に基づいて説明する。
【００２４】
図１〜図４を用いて第一構成例について説明する。
【００２５】
第一構成例は、棒体支承部１を設けた基体２に抱持半体３を設けて前記棒体支承部１に当接せしめた棒体４に前記抱持半体３を被嵌して棒体４を抱持固定する棒体抱持金具Ａであって、前記基体２の一端に前記抱持半体３の基端を枢着し、この抱持半体３の先端に係止体５を設け、基体２の他端に軸杆18を横設し、ストッパー操作体７を設け、このストッパー操作体７に長孔19を設け、この長孔19に前記軸杆18を嵌挿することでストッパー操作体７を基体２の他端に枢着し、このストッパー操作体７に前記係止体５に係止可能な係止部８を設け、このストッパー操作体７を回動操作し且つ軸杆18に対してストッパー操作体７を上方にスライド移動することで前記基体２の他端からの突出量を大きくした際、前記係止部８を前記係止体５に係脱自在に係止できるように構成し、このストッパー操作体７を前記係止体５に前記係止部８を係止した状態を保持した状態で回動操作し且つ軸杆18に対してストッパー操作体７を下方にスライド移動することで前記基体２の他端部分にこのストッパー操作体７を添設状態に回動配設し得るように構成して、前記棒体４を前記基体２の棒体支承部１と抱持半体３とで抱持した際、このストッパー操作体７を基体２の他端部分に添設状態に回動配設し且つこのストッパー操作体７の回動によりストッパー操作体７が軸杆18に対してスライド移動して前記軸杆18が前記長孔19の一端に設けた軸杆係止部20に係止することで前記係止部８が前記係止体５から係脱不能となり棒体４が抱持固定され得るように構成した棒体抱持金具Ａに係るものである。
【００２６】
長孔19には乗越部21を設けており、前記ストッパー操作体７を前記基体２の他端部分に添設状態に回動配設し且つこのストッパー操作体７の回動によりストッパー操作体７が軸杆18に対してスライド移動して前記軸杆18が前記長孔19の一端に設けた前記軸杆係止部20に係止する際、この乗越部21を前記軸杆18が乗り越えて前記軸杆係止部20に係止するように構成している。
【００２７】
従って、棒体抱持金具Ａに棒体４を抱持固定した状態において、抱持半体３が上方に回動しようとすると、この抱持半体３に係止部５及び係止体８を介して連結されているストッパー操作体７が前記軸杆18に沿って上方にスライド移動しようとすることになるが、この際、軸杆18が前記乗越部21を乗り越えなければならない為、この乗り越え力以上の力が抱持半体３に作用しない限り、抱持半体３が棒体４を抱持する状態が解除されないことになる。
【００２８】
また、この前記乗越部21は、前記長孔19を途中で屈曲する長孔19に構成し、この屈曲部を前記乗越部21に設定して設けている。
【００２９】
この長孔19の形状は、上方に行く程棒体４から離れる傾斜長孔部に構成され、この傾斜長孔19の途中に屈曲部が設けられ、この屈曲部より上方が前記傾斜長孔部より更に棒体４から離れる傾斜長孔部（水平長孔でも良い）に形成され、この傾斜長孔部の先端が前記軸杆係止部20に設定されている。
【００３０】
ストッパー操作体７は平断面視コ字状に形成されており、対向する遊離突片６・６間に横杆９が架設され、この横杆９が前記係止部８に設定されている。
【００３１】
また、この対向する遊離突片６・６に夫々前記長孔19を設けている。
【００３２】
基体２の他端部分には、前記ストッパー操作体７を基体２の他端部分に添設した際、ストッパー操作体７が被嵌される被嵌部15を設けている。従って、ストッパー操作体７の基体２の他端部分への添設作業は、このストッパー操作体７と被嵌部15との被嵌嵌合により回動がガイドされることになり、棒体４を抱持する際に最も重要なストッパー操作体７の最後の回動操作を確実に行えることになる。
【００３３】
また、この被嵌部15は、この被嵌部15に被嵌したストッパー操作体７及び前記係止部８が前記基体２の側面視の左右から突出しないように構成している。
【００３４】
抱持半体３に設けられる前記係止体５は舌片状に形成されており、この舌片状の係止体５に前記横杆９を押圧係止せしめることで係止体５と係止部８との係止を達成するように構成している。
【００３５】
この係止体５は、この舌片状の係止体５の上向き度合いを上下調整することで前記基体２の棒体支承部１と抱持半体３とで前記棒体４を抱持する力を増減する抱持力増減機構22にもなっている。具体的には、係止体５の上向き度合いを上方に調整すれば、ストッパー操作体７を下方へスライド移動して前記長孔19内で前記軸杆18が軸杆係止部20に位置する状態においてストッパー操作体７の係止部８が係止体５を強く押圧することになり、必然的に抱持半体３が棒体４を押圧する力も強くなり、棒体４が強固に抱持固定されることになる。また、係止体５の上向き度合いを下方に調整すれば、抱持半体３が棒体４を固定する力は弱くなる。
【００３６】
また、このストッパー操作体７の先端部には、前記基体２の他端部分に添設状態としたストッパー操作体７を回動操作する際、指を引っ掛けることができる指掛部16をストッパー操作体７の先端部を反り返らせる形状に設定して設けている。
【００３７】
また、抱持半体３の係止体５の先端は上方に反り返る形状に構成されており、この反返部が、係止体５への係止部８の係止が解除されることを防止する作用と、抱持半体３を回動操作する際の指掛部としての作用とを果たす。
【００３８】
尚、図示した棒体支承部１は棒体４の外周形状に略合致する円弧状に形成しているが、棒体支承部１と棒体４の摩擦係数などを考慮して棒体支承部１をギザギザ状に形成しても良い。また、全体は金属製である。
【００３９】
以下、第一構成例の使用方法について詳述する。
【００４０】
先ず、棒体支承部１に棒体４を載置し、一方、基体２の一端に枢着されている抱持半体３を回動操作して前記棒体４に抱持半体３を被嵌させる。
【００４１】
続いて、基体２に添設されているストッパー操作体７を上方へ回動操作し、且つ、このストッパー操作体７を上方へスライド移動せしめることで基体２の他端の突出量を大きくして係止部８（横杆９）を前記係止体５に係脱可能にし、この係止部８を係止体５に係止する（図３参照）。尚、この状態において、軸杆18は長孔19内の下方に位置することになる。
【００４２】
続いて、ストッパー操作体７を下方へ回動し、且つ、ストッパー操作体７を下方へスライド移動せしめることで基体２の他端の突出量を小さくして係止部８を前記係止体５に係脱可能にし、この係止部８を係止体５上に被嵌係止する（図３参照）。尚、この状態において、軸杆18は長孔19内の途中にして乗越部21の直前に位置することになる。
【００４３】
続いて、ストッパー操作体７を更に下方へ回動し、このストッパー操作体７の長孔19内の軸杆18が乗越部21を乗り越え、且つ、この軸杆18が軸杆係止部20に位置するようにする（図４参照）。このストッパー操作体７の操作により、前記係止体５上に被嵌係止していた係止部８が係止体５を強く押圧し（即ち、抱持半体３が棒体４を押圧する。）、この係止部８の押圧によって抱持半体３が回動操作不能となり、棒体４の固定作業が終了する。
【００４４】
このようにして、一旦、ストッパー操作体７により抱持半体３を回動操作不能にすると、例えば、不意に棒体４を上方に持ち上げる力が加えられてこの棒体４により抱持半体３が上方へ回動させられようとしても、抱持半体３の係止体５に係止された係止部８がストッパー操作体７を上方へ引っ張ろうとするが、ストッパー操作体７の長孔19内の軸杆18が軸杆係止部20に係止された状態が維持され、しかも、長孔19内の軸杆18が乗越部21を乗り越えなければストッパー操作体７はスライド移動及び上方への摺動ができず、よって、このストッパー操作体７の係止部８が係止体５を係止した状態を維持することになり、棒体４の抱持固定作用が維持されることになる。
【００４５】
また、棒体４の抱持固定を解除する際には、前記ストッパー操作体７を上方に回動して長孔19内の軸杆18が乗越部21を乗り越えるようにし、この操作によって係止部８と係止体５との押圧係止を解除する。
【００４６】
実験によれば、上記構成の棒体抱持金具Ａは、棒体４に８００ｋｇ以上の荷重が加わっても、ストッパー操作体７が回動したりせず、棒体４の抱持固定作用が維持されることが確認された。
【００４７】
第一構成例は上述のように構成したから、抱持半体３やストッパー操作体７を回動させたり、ストッパー操作体７をスライド移動したりするだけの簡単な操作によって棒体４を棒体抱持金具Ａにスムーズに固定することができ、しかも、ストッパー操作体７を回動したりスライド移動したりするだけで棒体４の取り外しも簡単且つスムーズに行うことができる実用性，作業性に秀れた棒体抱持金具となる。
【００４８】
また、長孔19内の軸杆係止部20に係止された状態の軸杆18が乗越部21を乗り越えない限りストッパー操作体７が回動したりスライド移動したりすることができないから、この棒体抱持金具Ａに固定された棒体４に荷重が作用しても、軸杆18が乗越部21を乗り越える力以下では前記固定が解除されないことになり、それだけ強固に棒体４を抱持固定できる実用性，安全性に秀れた棒体抱持金具となる。
【００４９】
また、抱持半体３は、係止体５などの構成部分を一体に設けることができるから、金属板からのプレス加工などの簡易な製造手段により棒体抱持金具Ａを製造することが可能な生産性に秀れた棒体抱持金具となる。
【００５０】
また、ストッパー操作体７の巾を添設する基体２の側面視における左右巾より巾狭く構成し、ストッパー操作体７及び係止部８が基体２の左右から突出しないように構成したから、誤ってこのストッパー操作体７に別の棒体や足などを引っ掛けたりしにくく、係止部８と係止体５との押圧係止が解除されて棒体抱持金具Ａに固定してある棒体４が外れてしまうことがなく確実に棒体抱持金具Ａに棒体４を固定することができるより一層実用性に秀れた棒体抱持金具となる。
【００５１】
図５を用いて第二構成例について説明する。
【００５２】
第二構成例は、第一構成例において使用した棒体抱持金具Ａの基体２に連結部（図示せず）を設けて２つの棒体抱持金具Ａ・Ａを連結部で連結するとともにこの連結された棒体抱持金具Ａ・Ａ同志が回動自在及び回動不能になるように構成し、棒体４を交叉若しくは平行に連結して足場を形成する際、例えば図示したように、２本の棒体４を交叉状態とし、この棒体４同志を前記２つ連結された棒体抱持金具Ａで一旦仮連結し、続いて、この仮連結した棒体４同志を公知の足場用棒体抱持金具で連結し、その後、この足場用棒体抱持金具で連結した棒体４から前記２つ連結された棒体抱持金具Ａ・Ａを取り外し、以下、この作業の繰り返しによって棒体４を連結して足場を形成する方法に係るものである。
【００５３】
連結部は、夫々の基体２・２の底部平面部に孔部を設け、２つの基体２・２の孔部の位置を合わせて孔部にボルトなどの螺子体を挿入し、このボルトにナットなどの螺着体を螺着して構成しており、このボルト・ナットを緩めると一方の棒体抱持金具Ａは他方の棒体抱持金具Ａに対して任意に回動自在となり、一方、ボルト・ナットを締めると一方の棒体抱持金具Ａは他方の棒体抱持金具Ａに対して回動不能となる。
【００５４】
尚、棒体抱持金具Ａ・Ａに抱持された棒体４に８００ｋｇｆ程度の荷重が作用しても、棒体抱持金具Ａ・Ａから棒体４が外れたりしないように設定する。
【００５５】
また、夫々の棒体抱持金具Ａに棒体４を着脱する方法については第一構成例と同様である。
【００５６】
従って、第二構成例は第一構成例と同様極めて簡単な操作でスムーズに２つの棒体４の取り付け，取り外しが行える上、２つの棒体４の取り付け角度に応じて棒体抱持金具Ａ・Ａの回動角度を調整して棒体４同志を連結固定できる為、棒体４を交叉若しくは平行状態で連結して足場を形成する際、作業者が１人でも片手で棒体４を支持しながらもう片手で棒体抱持金具Ａ・Ａを操作して棒体４同志を仮連結し、続いて、この仮連結された棒体４を公知の足場用棒体抱持金具を両手で操作して連結することにより１人でも簡単に棒体４を連結していくことができる実用性に秀れた足場形成方法となる。
【００５７】
また、棒体抱持金具Ａの棒体４を抱持する力が強力な為、この仮連結用の棒体抱持金具Ａ・Ａをそのまま足場用棒体抱持金具とすることもできる実用性に秀れた足場形成方法となる。
【００５８】
尚、連結する棒体抱持金具Ａは２つでなくとも、連結しようとする棒体４の本数によって例えば３つ等でも良い。
【００５９】
また、この２つ以上連結された棒体抱持金具Ａ・Ａは、例えば複数の棒体４を平行或いは交叉状態に連結して雪囲い等の組体を作る際にも使用することができ、例えば、基体２の底部に設けた連結部によって２つの棒体抱持金具Ａ・Ａを連結し、この連結した２つの棒体抱持金具Ａ・Ａの一方の棒体抱持金具Ａを地面から立設した棒体４に固定し、続いて、地面と平行の棒体４を他方の棒体抱持金具Ａで固定できるように棒体抱持金具Ａを回動操作し、この棒体抱持金具Ａに棒体４を固定し、以下、順次棒体４・４同志の交叉部において棒体抱持金具Ａ・Ａに棒体４・４を固定して雪囲いを作ることができる。
【００６０】
即ち、第二構成例において使用した２つ連結された棒体抱持金具Ａ・Ａは、２つの棒体抱持金具Ａ・Ａの連結角度を所望の角度に調整して平行状態の棒体４や交叉状態の棒体４を夫々棒体抱持金具Ａ・Ａに固定することができ、この棒体４の固定作業もストッパー操作体７の回動やスライド移動によってワンタッチで行うことができ、例えば足場や雪囲い等を作る場合には、従来の公知の足場用棒体抱持金具やロープやワイヤーなどで棒体４を縛り付ける方法に比べ極めてスムーズに組み立て作業を行うことができて作業時間も大幅に短縮できることとなり、よって、高所で作業する場合にも簡単に作業できるから安全に作業を行えることになる実用性，作業性，作業コスト安に秀れた棒体抱持金具となる。
【００６１】
また、その余は第一構成例と同様である。
【００６２】
尚、連結部はボルト・ナットによって止着する構成に限らず、例えばリベット等で軸着しても良いし、基体２の底部平面部に係合部を設けたものと係止部を設けたものとを別体に作成し、これらを係合して回動自在及び回動不能にできるように構成しても良い。
【００６３】
図６を用いて第三構成例について説明する。
【００６４】
第三構成例は、第一構成例の棒体抱持金具Ａを用い、この棒体抱持金具Ａを工事現場などの危険地帯を区画するために棒体４によって連結されるバリケード体Ｂに付設されており、この棒体抱持金具Ａ付バリケード体Ｂは下方程巾広く斜設した脚体13により形成し、この脚体13間に横桟14を配設し、この横桟14に連結部12を介して棒体抱持金具Ａを連結して左右回動自在に構成したものである。
【００６５】
また、図中符号11は、夜間などにおいて発光し、バリケード体Ｂを目立たせるための照明部である。
【００６６】
第三構成例は上述のように、バリケード体Ｂに前記棒体抱持金具Ａを付設したから、前記第一構成例と同様に棒体４をスムーズに棒体抱持金具Ａ（即ち、バリケード体Ｂ）に固定することができ、棒体４の取り外しも簡単且つスムーズに行うことができる実用性，作業性，作業コスト安に秀れた棒体抱持金具付バリケード体となる。
【００６７】
また、バリケード体Ｂを下方程巾広く斜設した脚体13間に横桟14を配設した構成とし、この横桟14に前記棒体抱持金具Ａの基体２を設けたから、棒体抱持金具Ａが脚体13や横桟14によって保護され、工事現場作業においても不意にストッパー操作体７等に回動作用が加えられたりせず、より一層確実に棒体４が棒体抱持金具Ａ（棒体抱持金具Ａ付バリケード体Ｂ）に固定されることになり、必然的に棒体４で連結されたバリケードＢが分解したりせず安定状態で立設されることになるより一層実用性に秀れた棒体抱持金具付バリケード体となる。
【００６８】

[0023]
【Example】
A specific embodiment of the present invention will be described with reference to the drawings.
[0024]
First using FIGS. 1 to 4In the configuration exampleexplain about.
[0025]
firstConfiguration exampleA rod body 4 provided with a holding half 3 on a base body 2 provided with a rod supporting part 1 and fitted with the holding half 3 on a rod 4 brought into contact with the rod supporting part 1; Is a rod-holding metal fitting A for holding and fixing a base end of the holding half 3 at one end of the base 2, and a locking body 5 is provided at a distal end of the holding half 3. A shaft 18 is provided laterally at the other end of the base 2, a stopper operating body 7 is provided, an elongated hole 19 is provided in the stopper operating body 7, and the shaft 18 is inserted into the elongated hole 19 to stop the stopper. An operating body 7 is pivotally attached to the other end of the base 2, and a locking portion 8 that can be locked to the locking body 5 is provided on the stopper operating body 7. When the amount of protrusion from the other end of the base body 2 is increased by sliding the stopper operation body 7 upward with respect to 18, the locking portion 8 can be removably locked to the locking body 5. The stopper operating body 7 is rotated while holding the state where the locking portion 8 is locked to the locking body 5, and the stopper operating body 7 is moved downward with respect to the shaft rod 18. The stopper operation body 7 is attached to the other end portion of the base 2 by being slidably moved to the other end of the base 2, and the rod 4 is attached to the rod support 1 of the base 2. When held by the holding half 3, the stopper operating body 7 is rotatably disposed in a state attached to the other end of the base 2, and the stopper operating body 7 is rotated by the rotation of the stopper operating body 7. The locking portion 8 is disengaged from the locking body 5 by sliding with respect to the shaft 18 and locking the shaft 18 with a shaft locking portion 20 provided at one end of the elongated hole 19. The present invention relates to a rod holding fixture A configured so that the rod 4 cannot be held and can be held and fixed.
[0026]
The elongate hole 19 is provided with a ride-over portion 21. The stopper operating body 7 is rotatably disposed on the other end of the base 2 in a state of being attached to the other end of the base 2, and the stopper operating body 7 is rotated by the rotation of the stopper operating body 7. Is slid with respect to the shaft rod 18, and when the shaft rod 18 is locked by the shaft rod locking portion 20 provided at one end of the elongated hole 19, the shaft rod 18 passes over the riding-over portion 21. It is configured to lock to the shaft rod locking portion 20.
[0027]
Therefore, when the holding half 3 tries to rotate upward in a state where the rod 4 is held and fixed to the rod holding metal A, the holding portion 5 and the locking body 8 are attached to the holding half 3. The stopper operating body 7 which is connected via the shaft will attempt to slide upward along the shaft 18, but at this time, since the shaft 18 has to get over the riding section 21, Unless a force higher than the overcoming force acts on the holding half 3, the state in which the holding half 3 holds the rod 4 is not released.
[0028]
Further, the crossover portion 21 is formed by forming the long hole 19 into a long hole 19 that is bent in the middle, and the bent portion is set and provided in the crossover portion 21.
[0029]
The shape of the long hole 19 is constituted by a slanted long hole portion which is further away from the rod body 4 as going upward, and a bent portion is provided in the middle of the slanted long hole 19, and the upper portion of the bent portion is the slanted long hole portion Further, a slanted long hole (a horizontal long hole may be provided) further away from the rod body 4, and the tip of the slanted long hole is set to the shaft rod locking portion 20.
[0030]
The stopper operating body 7 is formed in a U-shape in a plan cross section, and a horizontal rod 9 is provided between the opposed protruding pieces 6, 6, and the horizontal rod 9 is set to the locking portion 8.
[0031]
The opposed protruding pieces 6 are provided with the elongated holes 19, respectively.
[0032]
The other end of the base 2 is provided with a fitting portion 15 to which the stopper operating body 7 is fitted when the stopper operating body 7 is attached to the other end of the base 2. Therefore, when the stopper operating body 7 is attached to the other end portion of the base 2, the rotation is guided by the fitted engagement between the stopper operating body 7 and the fitted portion 15, and the rod body 4 is attached. , The last pivoting operation of the stopper operation body 7, which is most important, can be reliably performed.
[0033]
The fitted portion 15 is configured such that the stopper operating body 7 and the locking portion 8 fitted to the fitted portion 15 do not protrude from the left and right sides of the base 2 when viewed from the side.
[0034]
The locking member 5 provided on the holding half 3 is formed in the shape of a tongue, and the locking member 5 is engaged with the locking member 5 by pressing the horizontal rod 9 to the locking member 5 having the shape of a tongue. It is configured to achieve locking with the stop portion 8.
[0035]
The locking body 5 holds the rod 4 by the rod supporting portion 1 and the holding half 3 of the base 2 by adjusting the upward degree of the tongue-shaped locking body 5 upward and downward. It is also a holding force increasing / decreasing mechanism 22 for increasing / decreasing the force. Specifically, if the upward degree of the locking body 5 is adjusted upward, the stopper operating body 7 is slid downward and the shaft 18 is positioned at the shaft locking portion 20 in the elongated hole 19. In this state, the locking portion 8 of the stopper operating body 7 strongly presses the locking body 5, so that the holding half 3 inevitably presses the rod 4 strongly, and the rod 4 is held firmly. It will be held and fixed. Further, if the upward degree of the locking body 5 is adjusted downward, the force by which the holding half 3 fixes the rod body 4 becomes weak.
[0036]
A stopper attached to the other end of the base 2 is provided at the tip of the stopper operating body 7.operationWhen the body 7 is rotated, a finger hook 16 on which a finger can be hooked is set in a shape that allows the tip of the stopper operating body 7 to bend.
[0037]
Further, the tip of the locking body 5 of the holding half 3 is configured to be bent upward, and this rebound portion is used to confirm that the locking of the locking portion 8 to the locking body 5 is released. The function of preventing the rotation and the function of a finger hook when the holding half 3 is rotated are performed.
[0038]
Although the illustrated rod supporting portion 1 is formed in an arc shape that substantially matches the outer peripheral shape of the rod 4, the rod supporting portion 1 is considered in consideration of the coefficient of friction between the rod supporting portion 1 and the rod 4. 1 may be formed in a jagged shape. The whole is made of metal.
[0039]
Below, the firstConfiguration exampleHow to use will be described in detail.
[0040]
First, the rod 4 is placed on the rod support 1, while the holding half 3 pivotally attached to one end of the base 2 is operated to rotate the holding half 3 on the rod 4. Fit.
[0041]
Subsequently, the stopper operating body 7 attached to the base 2 is rotated upward, and the stopper operating body 7 is slid upward to increase the amount of protrusion of the other end of the base 2. The locking portion 8 (lateral rod 9) is made detachable from the locking body 5, and the locking portion 8 is locked to the locking body 5 (see FIG. 3). In this state, the shaft 18 is located below the long hole 19.
[0042]
Subsequently, the stopper operation body 7 is rotated downward, and the stopper operation body 7 is slid downward, thereby reducing the amount of protrusion of the other end of the base 2 and moving the locking portion 8 to the locking body 5. The locking portion 8 is fitted and locked on the locking body 5 (see FIG. 3). In this state, the shaft rod 18 is located in the middle of the elongated hole 19 and immediately before the riding portion 21.
[0043]
Subsequently, the stopper operating body 7 is further rotated downward, so that the shaft 18 in the elongated hole 19 of the stopper operating body 7 rides over the riding-over portion 21, and the shaft 18 Position (see FIG. 4). By the operation of the stopper operating body 7, the locking portion 8 fitted and locked on the locking body 5 strongly presses the locking body 5 (that is, the holding half 3 presses the rod 4). Then, the holding half 3 becomes inoperable due to the pressing of the locking portion 8, and the fixing operation of the rod 4 is completed.
[0044]
In this way, once the holding half 3 is made unrotatable by the stopper operating body 7, for example, a force for suddenly lifting the rod 4 is applied, and the holding half 3 is Although the locking member 8 of the holding half 3 tries to pull the stopper operating body 7 upward even when the holding member 3 is rotated upward, the length of the stopper operating body 7 is long. The state in which the shaft 18 in the hole 19 is locked by the shaft locking portion 20 is maintained, and if the shaft 18 in the long hole 19 does not climb over the climbing portion 21, the stopper operating body 7 can slide and move. Sliding upward cannot be performed, and thus the state in which the locking portion 8 of the stopper operating body 7 locks the locking body 5 is maintained, and the holding and fixing action of the rod 4 is maintained. Will be.
[0045]
When the holding and fixing of the rod 4 is released, the stopper operation body 7 is rotated upward so that the shaft rod 18 in the elongated hole 19 passes over the riding-over section 21, and the locking operation is performed by this operation. The pressing and locking of the portion 8 and the locking body 5 is released.
[0046]
According to the experiment, the rod holding metal member A having the above configuration does not rotate the stopper operating body 7 even when a load of 800 kg or more is applied to the rod 4, and the holding and fixing operation of the rod 4 is not performed. It was confirmed that it would be maintained.
[0047]
firstConfiguration exampleIs constructed as described above, the rod body 4 is held by a simple operation such as rotating the holding half body 3 and the stopper operating body 7 or sliding the stopper operating body 7. A can be smoothly fixed to A, and the rod body 4 can be easily and smoothly removed by simply rotating or sliding the stopper operation body 7 and is excellent in practicality and workability. It becomes a rod holding bracket.
[0048]
Further, since the stopper operating body 7 cannot rotate or slide unless the shaft 18 locked in the shaft locking portion 20 in the elongated hole 19 gets over the climbing portion 21. Even if a load is applied to the rod 4 fixed to the rod holding fixture A, the fixing will not be released with a force lower than the force by which the shaft rod 18 passes over the riding-over section 21, so that the rod 4 is firmly fixed. This is a rod holding fixture that is practical and safe to hold and fix.
[0049]
In addition, since the holding half 3 can be integrally provided with components such as the locking body 5, the rod holding metal fitting A can be manufactured by a simple manufacturing means such as pressing from a metal plate. It will be a rod holding fixture with excellent possible productivity.
[0050]
In addition, the width of the stopper operating body 7 is configured to be narrower than the lateral width of the attached base 2 in a side view, and the stopper operating body 7 and the locking portion 8 are configured so as not to protrude from the left and right sides of the base 2. It is difficult for another rod or foot to be hooked on the lever operating member 7, and the rod fixed to the rod holding member A by releasing the locking between the locking part 8 and the locking body 5 is released. A rod holding metal fixture that is more practical than the rod body 4 can be securely fixed to the rod holding metal member A without the body 4 coming off.
[0051]
Second using FIG.Configuration exampleWill be described.
[0052]
secondConfiguration exampleIs the firstConfiguration exampleA connecting portion (not shown) is provided on the base body 2 of the rod holding metal member A used in the above-mentioned step, and the two rod holding members A are connected by the connecting portion, and the connected rod holding metal member A is connected. When A is configured to be rotatable and non-rotatable, and when the rods 4 are crossed or connected in parallel to form a scaffold, for example, as shown, the two rods 4 are crossed. The rods 4 are temporarily connected to each other temporarily by the two connected rod holding members A, and then the temporarily connected rods 4 are connected to each other by a known scaffold rod holding metal. Then, the two connected rod holding members A and A are removed from the rods 4 connected by the rod holding member for a scaffold, and the rods 4 are connected by repeating this operation. And a method for forming the same.
[0053]
The connecting portion is provided with a hole in the bottom flat portion of each of the bases 2, 2 and a screw body such as a bolt is inserted into the hole by aligning the positions of the holes of the two bases 2, 2 with a nut. When the bolts and nuts are loosened, one of the rod holding members A is freely rotatable with respect to the other rod holding member A. When the bolts and nuts are tightened, one of the rod holding members A cannot rotate with respect to the other rod holding member A.
[0054]
In addition, even if a load of about 800 kgf is applied to the rod 4 held by the rod holding members A, the rod 4 is set so as not to come off from the rod holding metal A.
[0055]
The method of attaching and detaching the rod 4 to and from each rod holding fixture A is described first.Configuration exampleIs the same as
[0056]
Therefore, the secondConfiguration exampleIs firstConfiguration exampleThe two rods 4 can be smoothly attached and detached by a very simple operation in the same manner as described above, and the rotation angle of the rod holding brackets A and A is adjusted in accordance with the mounting angle of the two rods 4 to adjust the rod. Since the bodies 4 can be connected and fixed, when the rods 4 are connected in a crossed or parallel state to form a scaffold, even one worker supports the rod 4 with one hand while holding the rod with the other hand. A. A is operated to temporarily connect the rods 4 to each other, and subsequently, the temporarily connected rods 4 are connected to each other by operating the well-known scaffolding rod holding metal fittings with both hands. This is a highly practical scaffold formation method that can easily connect the rods 4.
[0057]
Further, since the force for holding the rod 4 of the rod holding metal A is strong, the rod holding metal A for temporary connection can be directly used as a rod holding metal for a scaffold. It becomes a method of forming a scaffold with excellent properties.
[0058]
The number of the rod holding members A to be connected is not limited to two, but may be three depending on the number of rods 4 to be connected.
[0059]
Further, the two or more connected rod holding members A, A can be used, for example, when a plurality of rods 4 are connected in parallel or in an intersecting state to form an assembly such as a snow enclosure. For example, two rod holding members A, A are connected by a connecting portion provided at the bottom of the base 2, and one of the two rod holding members A, A of the connected two rod holding members A, is grounded. Then, the rod holding member A is rotated so that the rod 4 parallel to the ground can be fixed with the other rod holding metal member A. The rods 4 are fixed to the holding members A, and thereafter, the rods 4, 4 are fixed to the rod holding members A, A at the intersections of the rods 4, 4 in succession to form a snow enclosure.
[0060]
In other words, the secondConfiguration exampleThe two rod holding members A and A used in the above-described method are used to adjust the connection angle of the two rod holding members A and A to a desired angle, and to set the rod 4 in a parallel state or the rod in an intersecting state. The body 4 can be fixed to each of the rod holding members A. The fixing work of the rod 4 can also be performed by one-touch operation by rotating or sliding the stopper operating body 7, such as a scaffold or a snow enclosure. In the case of making, the assembling work can be performed extremely smoothly as compared with the conventional method of binding the rod body 4 with a scaffold rod holding metal fitting or a rope or a wire, and the working time can be greatly reduced. Therefore, since the work can be performed easily even when working at a high place, the work can be safely performed.

The metal fitting A is protected by the legs 13 and the horizontal rails 14, so that even when working on a construction site, the stopper operating body 7 and the like are not unexpectedly rotated, and the rod 4 is held more securely. It is fixed to the metal fitting A (the barricade body B with the metal body holding metal fitting A), so that the barricade B connected by the rod body 4 is inevitably stood upright without being disassembled. It becomes a barricade body with a rod holding metal fitting that is even more practical.
[0068]
Further, since the bar holding member A is configured to be rotatable left and right with respect to the barricade body B, even when the barricade body B and the bar 4 cannot cross each other, for example, when there is unevenness on the ground, the rod is held. By adjusting the rotation of the body holding bracket A, the bar 13 can be installed in a stable state without the legs 13 of the barricade body B floating off the ground. It becomes an attached barricade.
[0069]
The number of the barricade bodies B attached to the rod body 4 may be any number as long as it is two or more. Further, a barricade formed by attaching two or more rod holding members A to the barricade body B and increasing the number of the rods 4 connecting the barricade body B with the rod holding metal members A to two or three.
