Description

【０００１】
【発明の属する技術分野】
この発明は、仮設足場における手摺部材等の水平材に設けられる足場用楔受金具に関する。
【０００２】
【従来の技術】
建築中の家屋等の外周に組み立てられる仮設足場においては、各構成部材間の所要部分を楔により緊結固定するものが周知である。例えば図２３及び図２４に示す楔式仮設足場においては、一対の支柱（１）における外周の四箇所に、楔受用にコマ金具（１ａ）が溶接固定されており、手摺部材（２）における両端の楔片（２ａ）が、対応するコマ金具（１ａ）に打ち込まれて緊結固定されることにより、一対の支柱（１）間に手摺部材（２）が水平に架け渡されるように組み付けられる。更に手摺部材（２）には、踏板（３）の端部に設けられたフック（３ａ）が係合されて、踏板（３）が手摺部材（２）に組み付けられるものである。
【０００３】
また、この楔式仮設足場においては、手摺部材（２）の外周面に楔受用にコマ金具（２ｂ）が溶接固定されるとともに、踏板（３）の端部に楔片（３ｂ）が固定されており、この楔片（３ｂ）が手摺部材（２）のコマ金具（２ｂ）に打ち込まれて緊結固定されている。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記従来の楔式仮設足場において、手摺部材（２）のコマ金具（２ｂ）は溶接により固定されているため、踏板（３）の手摺部材（２）に対する緊結位置を変更することができず、汎用性に欠けるという問題を抱えている。
【０００５】
また手摺部材（２）のコマ金具（２ｂ）は、必ず使用するものではなく、例えば踏板（３）として楔片の付いていないものを、フック（３ａ）のみで手摺部材（２）に組み付ける場合もある。この場合、コマ金具（２ｂ）の付いていない手摺部材（２）を組み付けるのが通例であるが、コマ無しの手摺部材と、コマ付きの手摺部材とを適宜選択しながら足場を組み立てていくとなると、手摺部材の種分けにも労力を費やす必要があり、組立作業が面倒になるという問題が発生する。
【０００６】
なお、コマ金具を使用しない箇所に、コマ付きの手摺部材（２）を組み付けたとしても、足場構造自体に問題が生じることはないが、無意味なコマ金具が存在することにより、部材の有効利用を図ることができず、コストの増大を来す恐れもある。
【０００７】
この発明は、上記従来技術の問題を解消し、踏板等の楔片を、手摺部材等の水平材に位置変更自在に緊結固定できて、汎用性に優れるとともに、足場組立作業を容易に行える上更に、部材の有効利用及びコストの削減を図ることができる足場用楔受金具を提供することを目的とする。
【０００８】
【課題を解決するための手段】
上記目的を達成するため、この発明は、足場構成材の水平材に、その上方から跨る態様に離脱可能に嵌め込まれる外嵌部を有する金具構成体と、前記金具構成体に設けられ、前記外嵌部が水平材に外嵌された状態において、水平材から水平方向に沿って一方側及び他方側に所定の間隔をおいて配置される一方側楔受片及び他方側楔受片と、前記金具構成体がその外嵌部が水平材に外嵌された状態において上方への脱外を防止するための脱外防止手段とを備え、前記外嵌部が水平材に外嵌された状態において、前記水平材と前記楔受片との間に楔片が差し込まれた際に、前記外嵌部の内周面が前記水平材の外周面に圧接係合されて、前記楔片が前記水平材と前記楔受片とにより挟圧保持されるよう構成されてなるものを要旨としている。
【０００９】
この発明の足場用楔受金具においては、手摺部材等の水平材に取外可能に外嵌するものであるため、楔受が必要な場合にのみ、水平材に組み付けることにより、コマ金具等の楔受が無駄に存在するような不具合を防止でき、部材の有効利用を図ることができる。
【００１０】
更に本発明の楔受金具は、必要時に取り付けるものであるため、従来のように、コマ付きの水平材と、コマ無しの水平材とを種分けしながら組み付ける必要がなく、その分、作業者の負担を軽減することができる。
【００１１】
また本発明の楔受金具は、固定位置を自在に変更することができるため、足場の構成等に合わせて、取付位置を適当に調整することが可能である。
【００１２】
本発明においては、以下の形態を採用するのが好ましい。
【００１３】
すなわち本発明の第１態様は、前記金具構成体が、間隔をおいて対向配置される第１及び第２プレートを具備し、これらの両プレートの一方側間及び他方側間に、前記一方側楔受片及び他方側楔受片が架け渡し状に配置され、前記第１及び第２プレートの上端部における少なくとも両側部に、上方に向かうに従って外側に拡開する傾斜状のガイド片が設けられてなるものである。
【００１４】
この第１態様においては、楔片を打ち込む際に、楔片先端がガイド片によって所定の打ち込み位置に正確にガイドされるため、楔打ち込み作業を簡単かつ正確に行うことができる。
【００１５】
更に本発明の第１態様においては、前記金具構成体が、間隔をおいて対向配置される第１及び第２プレートを具備し、これらの両プレートの一方側間及び他方側間に、前記一方側楔受片及び他方側楔受片が架け渡し状に配置され、前記両プレートのうちいずれか一方に、前記水平材を挿通配置する水平材挿通孔が形成され、その挿通孔の内周縁部によって前記外嵌部及び前記脱外防止手段が形成されてなる構成を採用するのが良い。
【００１６】
すなわちこの構成を採用する場合には、水平材挿通孔内周縁部が水平材に係止することにより、楔受金具自体が脱外して脱落するのを確実に防止することができる。
【００１７】
また本発明の第１態様においては、前記水平材挿通孔が、小径の上孔とその上孔に連通する大径の下孔とを有するダルマ孔により構成され、そのダルマ孔の上孔内周縁部によって前記外嵌部が形成されてなる構成を採用するのが望ましい。
【００１８】
すなわちこの構成を採用する場合には、例えば水平材の端部に楔片が設けられてようとも、その楔片をダルマ孔に通過させることができるので、楔付きの水平材をダルマ孔に確実に挿通配置することができ、楔受金具を確実に組み付けることができる。
【００１９】
一方、本発明においては、以下の態様を採用することも可能である。
【００２０】
すなわち本発明の第２態様は、請求項１記載の足場用楔受金具において、前記金具構成体が、中間が上方に膨出するように半円筒状に湾曲形成されて、その湾曲部が前記外嵌部として構成された本体プレートを具備し、前記本体プレートの両側に、一方側及び他方側楔差込口が形成されるとともに、各差込口の外側縁部によって前記一方側楔受片及び他方側楔受片が形成され、前記外嵌部が水平材に外嵌された状態において、前記楔差込口に楔片が差し込まれた際に、前記外嵌部の内周面が前記水平材の外周面に圧接係合されて、前記楔片が前記水平材と前記楔受片とにより挟圧保持されるよう構成されてなるものである。
【００２１】
更にこの第２態様においては、前記脱落防止手段が、前記前記本体プレートから下方側に所定の間隔をおいて配置されるロック受片と、前記外嵌部が水平材に外嵌された状態において、水平材と前記ロック受片との間に抜き差し自在な楔状ロック部材とを有し、前記外嵌部が水平材に外嵌された状態において、前記楔状ロック部材が水平材とロック受片との間に圧入介在されることにより、前記外嵌部の内周面が前記水平材の外周面に圧接固定されるよう構成されてなるものを採用するのが良い。
【００２２】
すなわちこの構成を採用する場合には、楔方式により、楔受金具を水平材に確実に固定することができる。更に楔受金具を支柱等に組み付けられた水平材に、後付けで組み付けることができるので、組付手順が制約されず、足場組立作業をより一層簡単に行うことができる。
【００２３】
また、本発明においては、以下の態様を採用することも可能である。
【００２４】
すなわち本発明の第３態様は、請求項１記載の足場用楔受金具において、前記金具構成体が、間隔をおいて対向配置される第１及び第２プレートを具備し、これらの両プレートの一方側間及び他方側間に、前記一方側楔接合片及び他方側楔接合片が架け渡し状に配置され、前記第１及び第２プレートに、下向きに開放する第１切欠部及び第２切欠部が形成され、各切欠部の内周縁部によって前記外嵌部が形成されてなるものである。
【００２５】
更にこの第３態様においては、前記脱落防止手段が、前記第１及び第２プレート間に設けられ、水平材に磁気吸着自在な磁気吸着体により構成されてなるものを採用するのが好ましい。
【００２６】
すなわちこの場合には、楔受金具を水平材に対し簡単に着脱できる上、脱落も確実に防止することができる。
【００２７】
またこの第３態様においては、前記第１切欠部が、下向きの斜め他方側に向けて開放されるとともに、第２切欠部が、下向きの斜め一方側に向けて開放され、前記第１及び第２プレートを、前記水平材に対し水平面内において所定の傾斜角度で配置した状態において、前記第１及び第２切欠部が水平材にその上方から外嵌可能に構成される一方、前記第１及び第２切欠部が水平材に外嵌された状態において、前記第１及び第２プレートを、前記水平材に対し水平面内において直交配置されるよう回転させることにより、前記第１切欠部の開放縁部一方側が前記水平材の下方に配置されるとともに、前記第２切欠部の開放縁部他方側が前記水平材の下方に配置されて、前記第１及び第２プレートの前記水平材からの抜止めが図られるよう構成されてなるものを採用するのが良い。
【００２８】
すなわちこの構成を採用する場合には、楔受金具を水平材に確実に固定することができる。
【００２９】
【発明の実施の形態】
＜第１実施形態＞
図１ないし図５はこの発明の第１実施形態である楔受金具（Ｐ１）を示す図である。なおこの第１実施形態は、本発明の請求項１ないし４に関連するものである。
【００３０】
これらの図に示すように、本実施形態の楔受金具（Ｐ１）は、第１プレート（１１）を構成する第１金具構成体（１０）と、第２プレート（２１）及び両側楔受片（３０）（４０）を有する第２金具構成体（２０）とを具備している。
【００３１】
第１金具構成体（１０）は、金属板の成形加工品により構成されている。この第１金具構成体（１０）の中央には小径の上孔（１５）と大径の下孔（１６）とが連通して形成されたダルマ孔（１７）が形成されている。ダルマ孔（１７）の上孔（１５）は、後述する手摺部材（２）等の水平材に対応するサイズに形成されている。
【００３２】
ここで、ダルマ孔（１７）によって水平材挿通孔が構成され、ダルマ孔（１７）の内周縁部によって脱落防止手段が構成され、更にダルマ孔（１７）における上孔（１５）の内周縁部（１５ａ）によって外嵌部が構成されている。
【００３３】
更に第１金具構成体（１０）の上側部は、上方に向かうに従って外側に拡開するように傾斜して、ガイド片（１８）として構成されている。
【００３４】
第２金具構成体（２０）は、金属板の成形加工品により構成され、中間の第２プレート（２１）と、その第２プレート（２１）の両側縁部が内側に折曲されて形成された一方側楔受片（３０）及び他方側楔受片（４０）とを具備している。両楔受片（３０）（４０）は、下方に向かうに従って内側に配置されるように傾斜している。
【００３５】
第２プレート（２１）には、手摺部材（２）を収容し得る大きさの下向きの切欠部（２５）が形成されている。ここで、この切欠部（２５）の内周縁部（２５ａ）によって外嵌部が構成されている。
【００３６】
第２プレート（２１）の上側部は、上方に向かうに従って外側に拡開するように傾斜して、ガイド片（２８）として構成されている。
【００３７】
そして、第１プレート（１１）におけるダルマ孔（１７）の上孔（１５）と第２プレート（２１）の切欠部（２５）とが位置的に対応した状態で、第２金具構成体（２０）における両側楔受片（３０）（４０）の先端縁が、第１金具構成体（１０）の内面両側部に溶接固定される。
【００３８】
更に両金具構成体（１０）（２０）におけるガイド片（１８）（２８）の上端に、連結板（５０）の両端部が溶接固定されて、連結板（５０）がガイド片（１８）（２８）の上端部間に架け渡されるよう配置される。
【００３９】
上記構成の楔受金具（Ｐ１）は、以下のように仮設足場に組み付けられて、踏板（３）の楔片（３ｂ）等を緊結固定するものである。
【００４０】
すなわち図６に示すように、楔受金具（Ｐ１）をそのダルマ孔（１７）の上孔（１５）及び切欠部（２５）に手摺部材（２）等の水平材を挿通するよう配置し、上孔（１５）及び切欠部（２５）の内周縁部（１５ａ）（２５ａ）を手摺部材（２）に上方から外嵌させるように配置する。この嵌め込み状態においては、楔受金具（Ｐ１）は、手摺部材（２）に沿ってスライド自在に構成されている。
【００４１】
なお本実施形態において、楔受金具（Ｐ１）における第１金具構成体（１０）は、上孔（１５）の下側に大径の下孔（１６）を連通状態に形成して、ダルマ孔（１７）を形成しているため、図８に示すように、ダルマ孔（１８）に、手摺部材（２）の楔片（２ａ）を無理なく挿通させることができ、楔受金具（Ｐ１）を楔付き手摺部材（２）に確実に嵌め込むことができる。
【００４２】
こうして嵌め込んだ楔受金具（Ｐ１）を、必要に応じて、手摺部材（２）に沿ってスライドさせて、適当な位置に配置する。
【００４３】
続いて図７に示すように、ハンマー等を用いて、踏板の楔片（３ｂ）を、楔受金具（Ｐ１）における例えば一方側楔受片（３０）と手摺部材（２）との間に叩き込む。これにより、楔受金具（Ｐ１）における上孔（１５）の内周縁部（１５ａ）及び切欠部（２５）の内周縁部（２５ａ）が手摺部材（２）の外周面に圧接係合して、楔片（３ｂ）が手摺部材（２）の外周面と楔受金具（Ｐ１）における一方側楔受片（３０）の内面とに挟圧保持されると同時に、楔受金具（Ｐ１）が手摺部材（２）に対する位置規制が図られる。
【００４４】
この状態においては、楔片（３ｂ）の下端先端が、楔受金具（Ｐ１）における第２金具構成体（２０）よりも下側に配置される。
【００４５】
また本実施形態においては、上記したように、楔受金具（Ｐ１）の一方側に楔片（３ｂ）を緊結固定した状態で、図７の想像線に示すように、他方側にも楔片（３ｂ）を緊結固定できる。すなわち、上記と同様に、楔片（３ｂ）を楔受金具（Ｐ１）における他方側楔受片（４０）と手摺部材（２）との間に打ち込む。これにより、楔受金具（Ｐ１）における上孔（１５）の内周縁部（１５ａ）及び切欠部（２５）の内周縁部（２５ａ）が手摺部材（２）の外周面に圧接係合して、楔片（３ｂ）が手摺部材（２）と楔受金具（Ｐ１）の他方側楔受片（４０）とにより挟圧されて保持される。このように本実施形態の楔受金具（Ｐ１）においては、両側から２つの楔片（３ｂ）を緊結でき、両側に踏板等の足場構成材をそれぞれ連結することができる。
【００４６】
一方、緊結固定された楔片（３ｂ）を取り外すには、ハンマーを用いて楔片（３ｂ）の下端先端を下方から叩き上げれば良い。これにより、楔片（３ｂ）が手摺部材（２）と両側楔受片（３０）（４０）との間から抜け出して、楔片（３ｂ）を取り外すことができる。
【００４７】
以上のように、本実施形態の楔受金具（Ｐ１）によれば、手摺部材（２）に取外可能に外嵌するものであるため、楔受が必要な場合にのみ、手摺部材（２）に組み付けることにより、コマ金具等の楔受が無駄に存在するような不具合を防止できるので、部材の有効利用を図ることができ、コストの削減を図ることができる。
【００４８】
更に必要時にのみ、楔受金具（Ｐ１）を取り付ければ良いため、従来のように、コマ付きの手摺部材と、コマ無しの手摺部材とを種分けしつつ組み付ける等の面倒な組付作業を必要としないので、足場組立作業を簡単に行うことができる。
【００４９】
また楔受金具（Ｐ１）は、楔片（３ｂ）を打ち込まない状態では、手摺部材（２）に対しスライド自在に構成されているため、楔受金具（Ｐ１）の固定位置を自在に変更することができ、足場の構成等に合わせて、楔受金具（Ｐ１）の位置を適当に調整することにより、汎用性を向上させることができる。
【００５０】
また本実施形態の楔受金具（Ｐ１）は、そのダルマ孔（１７）に手摺部材（２）を挿通して、手摺部材（２）に組み付けるものであるため、その組付状態においては、楔受金具（Ｐ１）のダルマ孔内周縁部が手摺部材（２）に係止することにより、楔受金具（Ｐ１）が脱外することがなく、楔受金具（Ｐ１）が脱落するのを確実に防止することができる。
【００５１】
また本実施形態の楔受金具（Ｐ１）においては、第１及び第２プレート（１１）（２１）の上側部に外向きに折曲形成されたガイド片（１８）（２８）を形成しているため、楔片（３ｂ）を打ち込む際に、楔片（３ｂ）が楔受金具（Ｐ１）に対し多少位置ずれしていたとしても、楔片（３ｂ）の先端が、両ガイド片（１８）（２８）によってガイドされるため、楔片（３ｂ）を手摺部材（２）と楔受金具（３０）（４０）との間に確実に打ち込むことができ、楔打ち込み作業、ひいては足場組立作業を、より一層簡単に行うことができる。
【００５２】
＜第２実施形態＞
図９ないし図１３はこの発明の第２実施形態である楔受金具（Ｐ２）を示す図である。なおこの第２実施形態は、本発明の請求項１、５、６に関連するものである。
【００５３】
これらの図に示すように、本実施形態の楔受金具（Ｐ２）は、金具構成体としての本体プレート（６０）と、楔状ロック部材（７０）と、ロック受部材（８０）とを基本的な構成として備えている。
【００５４】
本体プレート（６０）は、金属板の成形加工品により構成され、中間が上方に膨出するように半円筒状に湾曲形成されて、外嵌部（６５）が形成されるとともに、両側に平板部（６１ａ）（６１ｂ）が形成されている。両平板部（６１ａ）（６１ｂ）から外嵌部（６５）の両側部にかけての領域には、平面視矩形状の楔差込口（６２ａ）（６２ｂ）が形成されており、平板部（６１ａ）（６１ｂ）における楔差込口（６２ａ）（６２ｂ）の外側縁部が、一方側及び他方側楔受片（６３ａ）（６３ｂ）として構成されている。
【００５５】
楔状ロック部材（７０）は、金属板の成形加工品により構成された溝型形状を有しており、底壁には長さ方向に沿って延びる長孔（７１）が形成されている。更にこのロック部材（７０）は、その高さ寸法が一方側（先端側）に向かうに従って低くなるように先細形状に形成されている。
【００５６】
ロック受部材（８０）は、２つのＵ字状部材（８１）（８２）を具備し、一方側のＵ字状部材（８２）における下側中間片には、Ｌ字状部材（８３）の下片先端が溶接固定されている。ここで、２つのＵ字状部材（８１）（８２）における下側中間片（８１ａ）（８２ａ）が、ロック受片として構成されている。
【００５７】
そして、金具本体（６０）の下面側にロック部材（７０）が配置されるとともに、ロック受部材（８０）における両Ｕ字状部材（８１）（８２）の両側片内にロック部材（７０）が配置された状態で、両Ｕ字状部材（８１）（８２）の両側片先端が、本体プレート（６０）の両側縁部に溶接固定されるとともに、他方のＵ字状部材（８２）におけるＬ字状部材（８３）の上向き片がロック部材（７０）の長孔（７１）に挿通されて、本体プレート（６０）の他方側平板部（６１ｂ）の下面に溶接固定される。
【００５８】
この組付状態において、楔受金具（Ｐ２）は、ロック部材（７０）が長孔（７１）の長さ範囲内においてスライド自在に構成されるとともに、長孔（７１）の内周縁部にロック受部材（８０）のＬ字状部材（８３）が係止することにより、ロック部材（７０）の脱外が防止される。
【００５９】
この楔受金具（Ｐ２）は、支柱等に組み付けられた手摺部材（２）に、後付けで組み付けることができる。すなわち図１４に示すように、ロック部材（７０）を、ロック受部材（８０）における両Ｕ字状部材（８１）（８２）の両側片間から抜き出して、本体プレート（６０）における外嵌部（６５）の内周面を下方側に開放した状態で、その下方開放部から手摺部材（２）を収容するようにして、本体プレート（６０）の外嵌部（６５）を手摺部材（２）に外嵌する。
【００６０】
次に図１５に示すように、ロック部材（６０）をＵ字状部材（８１）（８２）の両側片間に挿入して、外嵌部（６５）の内周面下方側を閉塞した後、必要に応じて、楔受金具（Ｐ２）を手摺部材（２）沿って移動させて所望の位置に配置する。なおこのスライド操作は、ロック部材（７０）をＵ字状部材（８１）（８２）内に挿入する前に行っても良い。
【００６１】
続いて、ロック部材（７０）をハンマーにより叩き込んで、ロック部材（７０）をＵ字状部材（８１）（８２）の下側中間片（８１ａ）（８２ａ）と手摺部材（２）との間に圧入介在させて、楔受金具（Ｐ２）を手摺部材（２）に緊結固定する。
【００６２】
その後、踏板等の楔片（３ｂ）を楔受金具（Ｐ２）における本体プレート（６０）の例えば他方側楔差込口（６２ｂ）に差し込んでハンマーにより叩き込む。これにより、外嵌部（６５）の内周面が手摺部材（２）の外周面に圧接係合して、楔片（３ｂ）が、手摺部材（２）と本体プレート（６０）における他方側楔受片（６３ｂ）とにより挟圧保持される。
【００６３】
なお、本実施形態の楔受金具（Ｐ２）においても、上記と同様に、踏板等の楔片（３ｂ）を、楔受金具（Ｐ２）における一方側楔差込口（６２ａ）側に緊結固定することができ、楔受金具（Ｐ２）の両側に踏板等の足場構成材をそれぞれ連結することができる。
【００６４】
一方、緊結固定された踏板楔片（３ｂ）を取り外すには、楔受金具（Ｐ２）におけるロック部材（７０）を上記とは逆方向に叩き出して、ロック部材（７０）をＵ字状部材（８１）（８２）から抜き取って、本体プレート（６０）の下面側を開放した後、踏板楔片（３ｂ）の下端先端を下方から叩き上げれば、踏板楔片（３ｂ）を取り外すことができる。
【００６５】
以上のように、本実施形態の楔受金具（Ｐ２）においても、手摺部材（２）に取外可能に外嵌するものであるため、楔受が必要な場合にのみ、手摺部材（２）に組み付けることにより、コマ金具等の楔受が無駄に存在するような不具合を防止できるので、部材の有効利用を図ることができ、コストの削減を図ることができる。
【００６６】
更に必要時にのみ、楔受金具（Ｐ２）を取り付ければ良いため、従来のように、コマ付きの手摺部材と、コマ無しの手摺部材とを種分けしながら組み付ける必要がなく、足場組立作業を簡単に行うことができる。
【００６７】
また楔受金具（Ｐ２）は、固定位置を自在に変更することができ、足場の構成等に合わせて、楔受金具（Ｐ２）の位置を適当に調整することにより、汎用性を向上させることができる。
【００６８】
また本実施形態の楔受金具（Ｐ２）は、本体プレート（６０）を手摺部材（２）に外嵌してロック部材（７０）により緊結固定するものであるため、支柱等に組み付けられた手摺部材（２）に、後付けで組み付けることができるので、組付手順が制約されず、足場組立作業をより一層簡単に行うことができる。
【００６９】
＜第３実施形態＞
図１６ないし図２０はこの発明の第３実施形態である楔受金具（Ｐ３）を示す図である。なおこの第３実施形態は、本発明の請求項１、７、８、９に関連するものである。
【００７０】
これらの図に示すように、本実施形態の楔受金具（Ｐ３）は、互いに同じ形状を有する第１及び第２金具構成体（１１０）（１２０）を具備している。
【００７１】
両金具構成体（１１０）（１２０）は、中間板部を構成する第１及び第２プレート（１１１）（１２１）と、第１及び第２プレート（１１１）（１２１）の両側縁部が内側に折曲されて形成された一方側折曲部（１３１）（１３１）及び他方側折曲部（１４１）（１４１）とを有している。
【００７２】
更に第１及び第２プレート（１１１）（１２１）には、略下向きの第１及び第２切欠部（１１５）（１２５）が形成されている。各切欠部（１１５）（１２５）の内周縁部上側（１１５ａ）（１２５ａ）は、手摺部材（２）等の水平材に対応する形状の外嵌部として構成されている。
【００７３】
第１金具構成体（１１０）における切欠部（１１５）の開放縁部のうち、一方側（１１６ａ）は、切欠部（１１５）の下側開放部の一方側を閉塞するように、突出状に形成されるとともに、開放縁部他方側（１１６ｂ）は、他方側に向かって傾斜するように形成されることにより、切欠部（１１５）が、下向きの斜め他方側に向かって開放されている。
【００７４】
第２金具構成体（１２０）における切欠部（１２５）は、上記とは逆に、つまり開放縁部のうち、一方側（１２６ａ）は、一方側に向かって傾斜するように形成されるとともに、開放縁部他方側（１２６ｂ）は、切欠部（１２５）の他方側を閉塞するように、突出状に形成されることにより、切欠部（１２５）が、下向きの斜め一方側に向かって開放されている。
【００７５】
そして、両金具構成体（１１０）（１２０）が、その一方側折曲部（１３１）（１３１）の先端部同士及び他方側折曲部（１４１）（１４１）の先端部同士が接合されるとともに、対向する第１及び第２プレート（１１１）（１２１）間における切欠部（１１５）（１２５）の上方に下向きコ字型の架橋金具（１５１）が架け渡し状に配置された状態で、溶接一体化される。
【００７６】
ここで、第１及び第２金具構成体（１１０）（１２０）間において対応する一方側折曲部（１３１）（１３１）によって、一方側楔受片（１３０）が構成されるとともに、対応する他方側折曲部（１４１）（１４１）によって、他方側楔受片（１４０）が構成される。
【００７７】
また両プレート（１１１）（１２１）間の架橋金具（１５１）の内部には、永久磁石等の磁気吸着体からなる脱落防止部材（１５０）が固定されている。
【００７８】
以上の構成の楔受金具（Ｐ３）は、支柱等に組み付けられた手摺部材（２）等の水平材に以下のようにして組み付けられる。すなわち図２１に示すように、楔受金具（Ｐ３）を、下面視において、手摺部材（２）に対し所定量傾斜させた状態に配置して、切欠部（１１５）（１２５）内に手摺部材（２）を嵌め込む。このとき、第１切欠部（１１５）は、下向き斜め他方側に向かって開放されるとともに、第２切欠部（１２５）は、下向き斜め一方側に向かって開放されているため、楔受金具（Ｐ３）を手摺部材（２）に対し傾斜させることにより、確実に切欠部（１１５）（１２５）の奥部（上部）まで挿入することができる。なお図２１においては、発明の理解を容易にするため、第１切欠部（１１５）における開放縁部一方側（１１６ａ）の下端面及び第２切欠部（１２５）における開放縁部他方側（１２６ｂ）の下端面にそれぞれ斜線によるハッチングを施している（以下の図２２においても同じ）。
【００７９】
この嵌込状態においては、脱落防止部材（１５０）が磁力によって手摺部材（２）に取り付けられているため、作業者が楔受金具（Ｐ３）から手を離したとしても、楔受金具（Ｐ３）が手摺部材（２）から脱落するような不具合を確実に防止することができる。
【００８０】
楔受金具（Ｐ３）を手摺部材（２）に嵌め込んだ後、図２２に示すように、楔受金具（Ｐ３）を、水平面内において回転させて、手摺部材（２）に対し直角に配置する。これにより、第１切欠部（１１５）における開放縁部一方側（１１６ａ）が手摺部材（２）の下方に配置されるとともに、第２切欠部（１２５）における開放縁部他方側（１２５ｂ）が手摺部材（２）の下方に配置されることにより、楔受金具（Ｐ３）が手摺部材（２）からの脱外が防止された状態で手摺部材（２）に固定される。
【００８１】
続いて、この楔受金具（Ｐ３）に、踏板等の楔片（３ｂ）を固定するには、楔片（３ｂ）を楔受金具（Ｐ３）における例えば一方側楔受片（１３０）と手摺部材（２）との間に上方から叩き込む。これにより、楔受金具（Ｐ３）における切欠部（１１５）（１２５）の内周縁部（１１５ａ）（１２５ａ）が手摺部材（２）の外周面に圧接係合して、楔片（３ｂ）が手摺部材（２）と一方側楔受片（１３０）とにより挟圧保持される。
【００８２】
なお、本実施形態の楔受金具（Ｐ３）においても、上記と同様に、踏板等の楔片（３ｂ）を、楔受金具（Ｐ３）における一方側に緊結固定することができ、楔受金具（Ｐ３）の両側に踏板等の足場構成材をそれぞれ連結することができる。
【００８３】
一方、緊結固定された踏板楔片（３ｂ）を取り外すには、踏板楔片（３ｂ）の下端先端を下方から叩き上げれば良い。
【００８４】
また楔受金具（Ｐ３）を手摺部材（２）から取り外すには、楔受金具（Ｐ３）を水平面内で所定量回転させて、両切欠部（１１５）（１２５）を下方側に開放させた後、脱落防止部材（１５０）の磁力に抗して上方へ抜き取ることにより、楔受金具（Ｐ３）を手摺部材（２）から取り外すことができる。
【００８５】
以上のように、本実施形態の楔受金具（Ｐ３）においても、手摺部材（２）に取外可能に外嵌するものであるため、楔受が必要な場合にのみ、手摺部材（２）に組み付けることにより、コマ金具等の楔受が無駄に存在するような不具合を防止できるので、部材の有効利用を図ることができ、コストの削減を図ることができる。
【００８６】
更に必要時にのみ、楔受金具（Ｐ３）を取り付ければ良いため、従来のように、コマ付きの手摺部材と、コマ無しの手摺部材とを使い分けて組み付ける必要がなく、足場組立作業を簡単に行うことができる。
【００８７】
また楔受金具（Ｐ３）は、固定位置を自在に変更することができ、足場の構成等に合わせて、楔受金具（Ｐ３）の位置を適当に調整することにより、汎用性を向上させることができる。
【００８８】
また本実施形態の楔受金具（Ｐ３）は、支柱等に組み付けられた手摺部材（２）に、後付けで組み付けることができるので、組付手順が制約されず、足場組立作業をより一層簡単に行うことができる。
【００８９】
なお上記各実施形態においては、水平材として手摺部材を例に挙げて説明したが、本発明はそれだけに限られず、手摺部材以外の水平材にも適用することができる。例えばブラケット、はね出しブラケット、はり枠部材、単管パイプ等、ほぼ水平に配置される部材であれば、どようような水平材にも適用することができる。
【００９０】
また上記各実施形態においては、楔受金具によって踏板の楔片（３ｂ）を緊結する場合について説明したが、それだけに限られず、本発明の楔受金具は、手摺部材の楔片等、他の楔片も緊結固定することができる。
【００９１】
なお、本発明は、楔受金具の一方側及び他方側の双方に、楔片を固定する場合に限られず、いずれか一方のみに楔片を固定する場合も含まれる。例えば本発明の楔受金具は、仮設足場の端部に設けられた手摺部材等の水平材に取り付けるようにしても良い。
【００９２】
【発明の効果】
以上のように、本発明の足場用楔受金具によれば、手摺部材等の水平材に取外可能に外嵌するものであるため、楔受が必要な場合にのみ、水平材に組み付けることにより、コマ金具等の楔受が無駄に存在するような不具合を防止できるので、部材の有効利用を図ることができ、コストの削減を図ることができる。更に必要時に取り付けるものであるため、従来のように、コマ付きの水平材と、コマ無しの水平材とを種分けしつつ組み付ける必要がなく、足場組立作業を簡単に行うことができる。また本楔受金具は、固定位置を自在に変更することができるため、足場の構成等に合わせて、取付位置を適当に調整することにより、汎用性を向上させることができるという効果がある。
【００９３】
本発明において、楔差込口にガイド片を形成する場合には、楔片打ち込み時に楔片先端がガイド片によって所定の打ち込み位置に正確にガイドされるため、楔打ち込み作業、ひいては足場組立作業を、より一層簡単に行うことができるという利点がある。
【００９４】
また本発明において、金具構成体に水平材を挿通配置するための水平材挿通孔を形成する場合には、水平材挿通孔内周縁部が水平材に係止することにより、楔受金具自体が脱外して、脱落するのを確実に防止することができるという利点がある。
【００９５】
更に本発明において、水平材挿通孔をダルマ孔により構成する場合には、たとえ水平材の端部に楔片が設けられていようとも、ダルマ孔に楔片を通過させることができるので、楔付き水平材をダルマ孔に確実に挿通配置することができ、ひいては楔受金具を水平材に確実に組み付けることができるという利点がある。

BACKGROUND OF THE INVENTION
The present invention relates to a scaffolding bracket for a scaffold provided on a horizontal member such as a handrail member in a temporary scaffold.
[0002]
[Prior art]
In a temporary scaffold assembled on the outer periphery of a house or the like under construction, it is well known that a required portion between each constituent member is tightly fixed by a wedge. For example, in the wedge-type temporary scaffold shown in FIG. 23 and FIG. 24, the top metal fitting (1a) is welded and fixed at four positions on the outer periphery of the pair of support columns (1), and both ends of the handrail member (2) are fixed. When the wedge piece (2a) is driven into the corresponding piece metal fitting (1a) and fastened and fixed, the handrail member (2) is assembled so as to be bridged horizontally between the pair of columns (1). Further, the handrail member (2) is engaged with a hook (3a) provided at an end portion of the footboard (3), and the footboard (3) is assembled to the handrail member (2).

However, in the conventional wedge-type temporary scaffold, since the top bracket (2b) of the handrail member (2) is fixed by welding, the fastening position of the tread (3) with respect to the handrail member (2) can be changed. However, it has a problem of lack of versatility.
[0005]
Further, the top bracket (2b) of the handrail member (2) is not necessarily used. For example, when the step board (3) without a wedge piece is assembled to the handrail member (2) only with the hook (3a) There is also. In this case, it is customary to assemble the handrail member (2) without the frame bracket (2b), but when the scaffold is assembled while appropriately selecting the handrail member without the frame and the handrail member with the frame. In this case, it is necessary to expend effort in classifying the handrail members, which causes a problem that the assembling work becomes troublesome.

[0039]
The wedge bracket (P1) having the above-described structure is assembled to a temporary scaffold as follows, and the wedge piece (3b) of the tread (3) is tightly fixed.
[0040]
That is, as shown in FIG. 6, the wedge bracket (P1) is arranged so that a horizontal member such as a handrail member (2) is inserted into the upper hole (15) and the notch (25) of the dharma hole (17), It arrange | positions so that the inner peripheral edge part (15a) (25a) of an upper hole (15) and a notch part (25) may be externally fitted to a handrail member (2) from upper direction. In this fitted state, the wedge bracket (P1) is configured to be slidable along the handrail member (2).
[0041]
In the present embodiment, the first bracket component (10) in the wedge bracket (P1) has a large-diameter lower hole (16) in a communicating state below the upper hole (15). Since (17) is formed, as shown in FIG. 8, the wedge piece (2a) of the handrail member (2) can be inserted through the dharma hole (18) without difficulty, and the wedge bracket (P1) Can be securely fitted into the handrail member with wedge (2).
[0042]
The wedge fitting (P1) fitted in this way is slid along the handrail member (2) as necessary, and is arranged at an appropriate position.
[0043]
Subsequently, as shown in FIG. 7, using a hammer or the like, the wedge piece (3b) of the tread plate is placed between, for example, the one-side wedge receiving piece (30) and the handrail member (2) in the wedge receiving bracket (P1). Strike. As a result, the inner peripheral edge (15a) of the upper hole (15) and the inner peripheral edge (25a) of the notch (25) in the wedge bracket (P1) are brought into pressure contact with the outer peripheral surface of the handrail member (2). The wedge piece (3b) is held between the outer peripheral surface of the handrail member (2) and the inner surface of the one side wedge receiving piece (30) of the wedge receiving fitting (P1), and at the same time the wedge receiving fitting (P1) is Position restriction with respect to the handrail member (2) is achieved.
[0044]
In this state, the lower end tip of the wedge piece (3b) is disposed below the second metal fitting component (20) in the wedge receiving metal fitting (P1).
[0045]
In this embodiment, as described above, the wedge piece (3b) is tightly fixed to one side of the wedge bracket (P1), and the wedge piece is also formed on the other side as shown by the imaginary line in FIG. (3b) can be tightly fixed. That is, similarly to the above, the wedge piece (3b) is driven between the other side wedge receiving piece (40) and the handrail member (2) in the wedge receiving metal fitting (P1). As a result, the inner peripheral edge (15a) of the upper hole (15) and the inner peripheral edge (25a) of the notch (25) in the wedge bracket (P1) are brought into pressure contact with the outer peripheral surface of the handrail member (2). The wedge piece (3b) is clamped and held by the handrail member (2) and the wedge receiving piece (40) on the other side of the wedge receiving metal fitting (P1). As described above, in the wedge bracket (P1) of the present embodiment, the two wedge pieces (3b) can be fastened from both sides, and the scaffold components such as treads can be connected to both sides.
[0046]
On the other hand, in order to remove the tightly fixed wedge piece (3b), the lower end of the wedge piece (3b) may be struck from below using a hammer. Thereby, the wedge piece (3b) comes out from between the handrail member (2) and the both-side wedge receiving pieces (30) and (40), and the wedge piece (3b) can be removed.
[0047]
As described above, according to the wedge bracket (P1) of the present embodiment, since it is detachably fitted to the handrail member (2), the handrail member (2 only when the wedge receiver is required) ), It is possible to prevent a problem that a wedge receiver such as a piece metal fitting is unnecessarily present, so that the members can be effectively used and the cost can be reduced.
[0048]
In addition, since it is only necessary to attach the wedge bracket (P1) only when necessary, it is necessary to perform troublesome assembly work such as assembling the handrail member with a frame and the handrail member without a frame as in the past. Therefore, the scaffold assembly work can be easily performed.
[0049]
Further, since the wedge bracket (P1) is configured to be slidable with respect to the handrail member (2) when the wedge piece (3b) is not driven, the fixing position of the wedge bracket (P1) is freely changed. The versatility can be improved by appropriately adjusting the position of the wedge bracket (P1) according to the structure of the scaffold.
[0050]
Further, since the wedge bracket (P1) of the present embodiment is one in which the handrail member (2) is inserted into the dharma hole (17) and assembled to the handrail member (2), Since the inner peripheral edge of the Dalma hole of the metal fitting (P1) is locked to the handrail member (2), the wedge metal fitting (P1) is not detached, and the wedge metal fitting (P1) is surely removed. Can be prevented.
[0051]
