【０００１】
【発明の属する技術分野】
本発明は、足場を組んでビル等の建物を築造する際に、枠組足場に、建築資材等の荷物を一時的に受ける荷受けステージのような付帯枠組み仮設物を設置するのに使用される取付金具に関する。
【０００２】
【従来の技術】
枠組足場に上記のような荷受けステージを設置する場合に、従来では、枠組足場の外側部所要高さ位置において、多数本の単管（鋼管からなる枠材単体）を縦横及び斜めにそれぞれ所要間隔に配し、それら単管の枠組足場側取付部及び単管相互の交差部を１箇所ずつパイプクランプにより固定して、梁部と手摺り部と斜材斜材とからなるステージ本体を形成し、このステージ本体の梁部外周に足場用の合板を敷設するなどして、枠組足場の外側部に荷受けステージを設置している。
【０００３】
【発明が解決しようとする課題】
然るに、上記のような荷受けステージの設置方法では、枠組足場外側部の地上から所要高さのところで、多数の単管とパイプクランプとによって、枠組足場との連結作業及び荷受けステージの枠組み作業を行うことから、パイプクランプの個数が数十個にもなって作業に非常な手間と時間を要し、しかも枠組足場外側部の高所位置で作業を行うため、その作業中に部材更には作業者が落下する危険性がある。また、荷受けステージは建築の進行に伴い枠組足場の高さが高くなると、枠組足場の高所側に付け替える必要があるが、上記のような方法では、ステージを付け替える度にステージの分解作業と組付け作業を行わなければならず、作業能率が非常に悪い。
【０００４】
そこで、上記のような荷受けステージの設置方法に代えて、地上で荷受けステージを予め枠組み形成しておき、このステージをクレーンで吊り上げて当該ステージの一端側を枠組足場外側部のステージ取付位置に外付け式に取り付けるようにする方法が考えられる。この方法によると、ステージを地上で枠組みし、これをクレーンで吊り上げて、そのまま枠組足場のステージ取付位置に取り付けるようにするため、作業能率が良い上に、作業の安全性を確保できる。
【０００５】
本発明は、このように地上で予め枠組み形成した荷受けステージ等の付帯枠組み仮設物を枠組足場の外側部に外付け式に取り付けるのに好適な枠組足場用取付金具を提供することを課題とする。
【０００６】
【課題を解決するための手段】
請求項１に係る発明の枠組足場用取付金具は、枠組足場に荷受けステージＳ等の付帯枠組仮設物を取り付けるための取付金具であって、枠組足場Ｗの縦枠材ａと横枠材ｂとの交差部において横枠材ｂ上に支持されると共に当該横枠材ｂの上位側で縦枠材ａを掴持する金具固定部Ｘと、前記付帯枠組仮設物の一端側所要部２３，９を取り付ける付帯枠組仮設物取付部Ｙとからなり、両側一対の腕板１２，１２をヒンジ１３により蝶着して、ヒンジ１３を挟んで両腕板１２，１２の一端側と他端側とが交互に開閉するように構成すると共に、両腕板１２，１２の一端側を前記金具固定部Ｘ、他端側を前記付帯枠組仮設物取付部Ｙとし、金具固定部Ｘは、それぞれ一対の対向する掴持腕部２１、２１及び跨嵌部２２，２２からなり、付帯枠組仮設物取付部Ｙは、一対の対向するボルト取付板部１７，１７からなり、両掴持腕部２１、２１により枠組足場Ｗの縦枠材ａを掴持してボルト１５で締結すると共に、枠組足場Ｗの横枠材ｂ上に両跨嵌部２２，２２を跨嵌させ、ボルト取付板部１７，１７間に付帯枠組仮設物Ｙの一端側所要部２３，９を挿入して当該一端側所要部２３，９を貫通するボルト１６により固定するようにしたことを特徴とする。
【０００８】

【００１１】
請求項５は、請求項１〜４のいずれかに記載の枠組足場用取付金具において、前記掴持腕部２１、２１には、枠組足場Ｗの縦枠材ａから突出する縦枠材連結ピンＰを逃がすための開口部４７を設けていることを特徴とする。
【００１２】
【発明の実施の形態】
図１は、枠組足場Ｗの外側部所要高さ位置に仮設された付帯枠組み仮設物としての荷受けステージＳを示す斜視図、図２は同荷受けステージＳの側面図、図３は同荷受けステージＳの平面図、図４は同荷受けステージＳの正面図である。枠組足場Ｗは、周知の構造であって、これらの図から分かるように、両側一対の縦枠材ａ，ａと両縦枠材ａ，ａをつなぐ横枠材ｂとからなる門形の建枠１を地上に一定間隔おきに配置すると共に、各建枠１を上下複数段に連結し、更に上下複数段に継ぎ足し連結される建枠１群相互を、斜めに交差する控え材（図示せず）により連結することによって形成されるもので、隣合う建枠１，１間には足場板Ｍが載設される。しかして、荷受けステージＳは、枠組足場Ｗのステージ取付位置に取り付けられた複数個（図示例では６個）の取付金具２によって取り付けられている。
【００１３】
荷受けステージＳは、枠組足場Ｗに対し外側へ水平に張り出すように延びて、互いに所定間隔に配置される例えば３個の梁枠３と、これら３個の梁枠３相互間に載設される複数枚（図示例では６枚）の足場板４と、３個の梁枠３のうち両端側の梁枠３、３に取り付けられる側部手摺り５，５と、中央の梁枠３の先端部に取り付けられる手摺り支柱６及びこれと各側部手摺り５との間に横架される手摺り複数本の枠７からなる前部手摺り８と、各梁枠３の先端下部に枢着される斜材９と、各斜材９の遊端部と各梁枠３の基端部とをつなぐ吊り材１０と、各手摺り５，８の下部に取り付けられる幅木１１と、から構成される。
【００１４】
前記荷受けステージＳの構造について図７〜図１１により更に詳しく説明すると、各梁枠３は、図７の（Ａ）〜（Ｅ）に示すように、基端側縦枠材２３と、先端側縦枠材２４と、上下横枠材２５，２５と、両横枠材２５，２５間に取り付けられた複数の補強枠材２６とで枠組み形成され、基端側縦枠材２３の上端部にはその最上位に、支持ピン２８が梁枠３と直交する方向に貫通突設され、その下方にボルト挿通孔２９，３０が穿設され、また基端側縦枠材２３の下部側には、枠組足場Ｗの縦枠材ａに係合する平面視円弧状係合部２７ａを有する係合部材２７が突設され、下横枠材２５の基端側下部にはピン孔３１ａ付き取付部片３１が突設されている。また、先端側縦枠材２４の下端にはコ字形ブラケット３２が固着され、これに斜材９の一端部がピン３３により枢着されている。この斜材９は、梁枠３の使用に際して前記吊り材１０を取り付けるまでは、図７の（Ａ）に示すように梁枠３と平行姿勢に折り畳んで、当該斜材９の他端側（遊端側）を、基端側縦枠材２３の下端に固着してあるコ字形ブラケット３４に嵌合して蝶ねじ３５により仮止めしている。また、斜材９の遊端側にはピン孔３６ａ付き取付部片３６が突設され、この取付部片３６と梁枠３側の前記取付部片３１とに前記吊り材１０の両端部が取り付けられるようになっている。
【００１５】
各側部手摺り５は、図８に示すように、基端側手摺り支柱３８と、先端側手摺り支柱３９と上部手摺り枠４０と下部手摺り枠４１とによって枠組み形成され、上部手摺り枠４０の基端側は、基端側手摺り支柱３８を越えて突出し、その突出端部に周知構造のパイプクランプ４２が取り付けられ、基端側手摺り支柱３８の下端には、梁枠３の横枠材２５に嵌合可能なコ字形ブラケット４３が固着されている。両手摺り支柱３８，３９の下端部対向側面には、幅木１１の両側端部を嵌合するコ字形ブラケット４４がそれぞれ固着されている。また、先端側手摺り支柱３９の上端及びその中間部位には、それぞれ屈曲自在なロック爪４５付きのピン４５が取り付けられている。
【００１６】
図１０の（Ａ）は幅木１１を示す正面図、（Ｂ）はその横断面図で、この図から分かるように、幅木１１は、前後及び中間の縦フレーム１１ａと、上下の横フレーム１１ｂと、網目状面板（一般にエキスパンドメタルと言う）１１ｃとによって形成される。図１１の（Ａ）及び（Ｂ）は吊り材１０を示すもので、この吊り材１０の両端部には、それぞればね付勢式ロック爪４６ａを有するピン４６が突設されている。この吊り材１０を梁枠３の基端部と斜材９の遊端部とに取り付ける際に、その一端部側のピン４６が、梁枠３の基端部側に突設された取付部片３１のピン孔３１ａに挿入されてロック爪４６ａによりロックされると共に、他端部側のピン４６が、斜材９の遊端部に取り付けられた取付部片３６のピン孔３６ａに挿入されてロック爪４６ａによりロックされるようになっている。
【００１７】
前部手摺り８については、図４に概略示しているだけで、詳細な図示は省略しているが、この前部手摺り８の手摺り支柱６は、前記側部手摺り５の先端側手摺り支柱３９と殆ど同じ構造（図８参照）で、当該支柱６の上端及びその中間部位にそれぞれ屈曲自在なロック爪付きのピンが取り付けられていると共に、当該支柱６の下端部に幅木１１の端部を嵌合するコ字形ブラケットが取り付けられている。また、前部手摺り８の各手摺り枠７は両端部にピン孔（図示省略）を有し、従って各手摺り枠７の取り付けにあたっては、手摺り枠７の一端部のピン孔を側部手摺り５の先端側手摺り支柱３９のピン４５に挿通させてロック爪４５ａでロックさせ、また他端部のピン孔を前部手摺り８の手摺り支柱６のピンに挿通させてロック爪でロックさせればよい。
【００１８】
さて、本発明に係る取付金具２の構造について図１２及び図１３を参照して説明すると、この取付金具２は、枠組足場Ｗの縦枠材ａと横枠材ｂとの交差部において横枠材ｂ上に支持されると共に当該横枠材ｂの上位側で縦枠材ａを掴持する金具固定部Ｘと、前記荷受けステージＳにおける梁枠３の基端側縦枠材２３または斜材９の下端部を取り付ける荷受けステージ取付部（付帯枠組み仮設物取付部）Ｙとによって構成される。
【００１９】
上記構造について更に詳述すると、この取付金具２は、両側一対の腕板１２，１２をヒンジ１３により蝶着して、ヒンジ１３を挟んで両腕板１２，１２の一端側と他端側とが交互に開閉するように構成すると共に、両腕板１２，１２の一端側を金具固定部Ｘとし、他端側を荷受けステージ取付部Ｙとしてなるもので、金具固定部Ｘは、それぞれ一対の対向する掴持腕部２１、２１及び跨嵌部２２，２２からなり、掴持腕部２１、２１は、枠組足場Ｗの縦枠材ａ外周面に嵌合する半円形状の嵌合部２１ａ，２１ａを有し、そして荷受けステージ取付部Ｙは、一対の対向するボルト取付板部１７，１７からなる。
【００２０】
金具固定部Ｘには、両掴持腕部２１、２１により枠組足場Ｗの縦枠材ａを掴持して締結するためのボルト１５が、両腕板１２，１２にわたって貫通するボルト挿通孔３７（図１３参照）に挿脱自在に挿通される。また、荷受けステージ取付部Ｙのボルト取付板部１７，１７にはその上端部に、荷受けステージＳにおける梁枠３の基端側縦枠材２３に突設した支持ピン２８を掛止させるためのピン掛止用溝１８，１８が設けられ、またこのピン掛止用溝１８，１８の下方には、ボルト挿通孔１９，１９、２０，２０が上下２段に設けてあって、上下いずれかのボルト挿通孔１９，１９または２０，２０にボルト１６が挿通される。
【００２１】
前記金具固定部Ｘの跨嵌部２２，２２は、図１３の（Ｃ）から分かるように、枠組足場Ｗの横枠材ｂの外周面形状に対応する円弧状に形成された嵌合部２２ａ，２２ａを有し、また掴持腕部２１、２１には、図１２及び図１３の（Ｂ）に示すように、枠組足場Ｗの縦枠材ａから突出する縦枠材連結ピンＰを逃がすための開口部４７が開口形成されている。この縦枠材連結ピンＰは、図４から分かるように、枠組足場Ｗの建枠１を継ぎ足すときに下段側建枠１の縦枠材ａと上段側建枠１の縦枠材ａとを連結するピンである。尚、図１２及び図１３において、１４はヒンジ１３のヒンジピンである。
【００２２】
次に、上述のように構成される取付金具２を使用して枠組足場Ｗに荷受けステージＳを仮設する方法について説明する。尚、この実施形態では、３個の梁枠３を使用して荷受けステージＳを形成している。先ず、地上において荷受けステージＳを枠組み形成する。即ち、３個の梁枠３を所定間隔で平行に配置し、その両端の梁枠３に側部手摺り５を取り付ける。そして、これら３個の梁枠３上に６枚の足場板４を載設し、中央の梁枠３の先端部に手摺り支柱６を取り付け、この手摺り支柱６と両側部手摺り５，５の先端側手摺り支柱３９，３９とに亘り上下の手摺り枠７を横架して、図４に示すような前部手摺り８を形成する。
【００２３】
この荷受けステージＳを枠組みする場合、各梁枠３の先端側縦枠材２４に枢着してある斜材９は、図７に示すように、予め梁枠３と平行状態に折り畳んで、この梁枠３に仮止めしておく。また、梁枠３に側部手摺り５を取り付けるには、梁枠３の先端側縦枠材２４の上端径小部２４ａ（図７参照）に側部手摺り５の先端側手摺り支柱３９の下端部を外嵌してピン（図示せず）止めすると共に、基端側手摺り支柱３８の下端に取り付けてあるコ字形ブラケット４３を梁枠３の横枠材２５の基端部に嵌合させてピン止めすればよい。また、前部手摺り８の手摺り支柱６は、その下端部を中央の梁枠３の先端側縦枠材２４の上端径小部に外嵌してピン止めした後、各手摺り枠７の各端部のピン孔を側部手摺り５の先端側手摺り支柱３９のピン４５に挿通させてロック爪４５ａでロックさせ、また他端部のピン孔を前部手摺り８の手摺り支柱６のピンに挿通させてロック爪でロックさせるようにすることにより、簡単に取り付けることができる。足場板４を各梁枠３上に載設するには、図５に部分的に示すように、両端部に２個ずつ設けてあるフック４ａを梁枠３の上横枠材２５に掛止させればよい。
【００２４】
上記のようにして荷受けステージＳを枠組み形成したならば、図示は省略するが、荷受けステージＳの四隅にロープＲを掛けて、このステージＳをクレーンで例えば１．８ｍ程度吊り上げて一旦止めた状態で、各梁枠３に沿って折り畳まれている斜材９の遊端側を下方へ引き降ろして、この斜材９の遊端部と各梁枠３の基端部との間に前述した要領で吊り材１０の両端部を取り付ける。
【００２５】
一方、枠組足場Ｗのステージ取付位置に上段側３個と下段側３個との６個の取付金具２をそれぞれ取り付ける（図１参照）。この取付金具２の取り付けにあたっては、各取付金具２に取り付けられる２本のボルト１５，１６を予め外しておき、そして両腕板１２，１２をヒンジ１３を中心に枢動させてその金具固定部Ｘを図１３（Ａ）の仮想線図示のように開口させ、この開口した金具固定部Ｘの掴持腕部２１、２１をその嵌合部２１ａ，２１ａを介して枠組足場Ｗの縦枠材ａに抱き合わせると共に、跨嵌部２２，２２を図１２及び図１３に示すように枠組足場Ｗの横枠材ｂ上に跨がらせた状態とし、そのあと金具固定部Ｘを閉じて、この金具固定部Ｘ側のボルト１５を両腕板１２，１２間に挿通し、ナット１５ａを締め付けて掴持腕部２１、２１で縦枠材ａを掴持し、こうして枠組足場Ｗの縦枠材ａと横枠材ｂとの交差部に取付金具２を取り付け固定する。このとき、図１３の（Ａ）及び（Ｂ）に示すように跨嵌部２２，２２の円弧状嵌合部２２ａ，２２ａが横枠材ｂの上面側に嵌合しているから、取付金具２の向きが所定方向に定まり、即ち取付金具２の荷受けステージ取付部Ｙが横枠材ｂの長手方向に向くように位置決めされる。
【００２６】
上記のようにして６個の取付金具２を枠組足場Ｗのステージ取付位置に取り付け固定した後、荷受けステージＳをクレーン（図示せず）で吊り上げて枠組足場Ｗのステージ取付位置へ移動させ、しかして荷受けステージＳの各梁枠３の基端側縦枠材２３を、上記６個の取付金具２のうち上段側３個の各取付金具２の荷受けステージ取付部Ｙの開口したボルト取付板部１７，１７間に挿入して、基端側縦枠材２３の上端部に取り付けてある支持ピン２８を上記ボルト取付板部１７，１７のピン掛止用溝１８，１８に掛止させると共に、上記基端側縦枠材２３の下部側に取り付けてある係合部材２７の円弧状係合部２７ａを枠組足場Ｗの縦枠材ａに当接係合させ、また各梁枠３に枢着してある斜材９の下端部を、下段側３個の各取付金具２の荷受けステージ取付部Ｙの開口したボルト取付板部１７，１７間に挿入する。この状態で荷受けステージＳは、３個の梁枠３の支持ピン２８を介して枠組足場Ｗの上段側３個の取付金具２に掛止されて荷重負担され、しかも各梁枠３の基端側縦枠材２３の下部側に取り付けてある係合部材２７が枠組足場Ｗの縦枠材ａに当接係合されているから、このままでも荷受けステージＳは安定状態を保つことができる。
【００２７】
しかる後、上段側３個の各取付金具２における荷受けステージ取付部Ｙ側のボルト１６を、ボルト取付板部１７，１７のボルト挿通孔１９，１９または２０，２０から梁枠３の基端側縦枠材２３に設けられたボルト挿通孔２９，３０に亘って挿通し、また下段側３個の各取付金具２における荷受けステージ取付部Ｙ側のボルト１６を、ボルト取付板部１７，１７のボルト挿通孔１９，１９または２０，２０から斜材９の下端部に設けられたボルト挿通孔４８（図７参照）に亘って挿通し、各ボルト１６のナット１６ａを締めればよく、これによって荷受けステージＳの各梁枠３を上段側と下段側の取付金具２に確実堅固に固定することができる。尚、各側部手摺り５を形成している上部手摺り枠４０の基端側は、パイプクランプ４２によって枠組足場Ｗの縦枠材ａに固定すればよい。
【００２８】
荷受けステージＳの側部手摺り５及び前部手摺り８のそれぞれ下部に取り付けられる各幅木１１は、地上に荷受けステージＳを枠組みするときに取り付けてもよいし、各梁枠３を各取付金具２に取り付け固定した後、このステージＳの足場板４の上で取り付けるようにしてもよい。
【００２９】
以上のようにして荷受けステージＳを枠組足場Ｗの外側部所要高さ位置に仮設するわけであるが、建築作業の進行により枠組足場が高くなって、この荷受けステージＳを一段高所側に付け替えるときには、各取付金具２における荷受けステージ取付部Ｙ側のボルト１６を取り外す一方、枠組足場Ｗの所定の付け替え位置に取付金具２を前記同様に取り付け、しかして上記荷受けステージＳをクレーンで吊り上げて、このステージＳの一端側を当該付け替え位置にある各取付金具２に前記同様の要領で取り付ければよい。
【００３０】
以上、図面によって説明したような荷受けステージＳの仮設工法では、荷受けステージＳを地上で予め枠組み形成し、この枠組みした荷受けステージＳをクレーンにより吊り上げて、枠組足場Ｗのステージ取付位置に取り付けた複数個の取付金具２に当該荷受けステージＳの一端側を取り付けるようにするから、仮設作業が容易且つ迅速に行え、作業能率を格段に向上させることができると共に、ステージＳの構成部材更には作業員が落下するおそれが少なく、作業上の安全性を確保することができる。特に、建築作業の進行により枠組足場が高くなって荷受けステージＳを一段高所側に付け替えるときの付け替え作業が容易に行える。
【００３１】
また、地上で荷受けステージＳを枠組みするにあたり、複数の梁枠３を所定間隔に配置して、その上に足場板４を載設し、両端側の梁枠３に側部手摺り５を取り付けると共に、梁枠３の先端側に前部手摺り８を取り付け、各梁枠３の先端部に斜材９の上端部を枢着することによって荷受けステージＳを形成し、この荷受けステージＳを吊り上げた状態で、各斜材９の他端部と各梁枠３の基端部との間に吊り材１０を取り付けた後、各梁枠３の基端部と各斜材９の下端部を、枠組足場Ｗ側の取付金具２に取り付けるようにするから、荷受けステージＳの構成部材点数が少なく、ボルトの締め付けを必要とする箇所が著しく軽減し、従ってステージＳの組み付けが非常に簡単となる。
【００３２】
そして、この荷受けステージＳを枠組足場Ｗに取り付けるための取付金具２は、枠組足場Ｗの縦枠材ａと横枠材ｂとの交差部において横枠材ｂ上に支持されると共に当該横枠材ｂの上位側で縦枠材ａを掴持する金具固定部Ｘと、荷受けステージＳにおける梁枠３の基端側縦枠材２３または斜材９を取り付ける荷受けステージ取付部Ｙとからなるため、金具固定部Ｘを横枠材ｂ上に支持させると共に当該横枠材ｂの上位側で縦枠材ａを掴持するだけで、取付金具２の取付位置の高さが決まり、従って高さ位置の調整をする必要がなく、位置決め作業が容易となり、また荷受けステージ取付部Ｙに荷受けステージＳにおける梁枠３の基端側縦枠材２３または斜材９を取り付けるだけでよいから、取付作業を簡単容易に行うことができる。そしてまた、金具固定部Ｘが縦枠材ａを掴持した状態で横枠材ｂ上に支持されるから、取付位置が上下にずれることがなく安定する。
【００３３】
また、この取付金具２は、両側一対の腕板１２，１２をヒンジ１３により蝶着して、ヒンジ１３を挟んで両腕板１２，１２の一端側と他端側とが交互に開閉するように構成すると共に、両腕板１２，１２の一端側を金具固定部Ｘ、他端側を付帯枠組仮設物取付部Ｙとしてなるものであって、金具固定部Ｘは、それぞれ一対の対向する掴持腕部２１、２１及び跨嵌部２２，２２からなり、付帯枠組仮設物取付部Ｙは、一対の対向するボルト取付板部１７，１７からなるため、両掴持腕部２１、２１により枠組足場Ｗの縦枠材ａを掴持してボルト１５で締結すると共に、枠組足場Ｗの横枠材ｂ上に両跨嵌部２２，２２を跨嵌させることにより、取付金具２の取付高さ位置が一定に決まると同時に、その取付けの向きが一定に決まり、即ち取付金具２の荷受けステージ取付部Ｙが常に横枠材ｂの長手方向に向くように位置決めされ、これがために複数個の取付金具２を使用する場合に、各取付金具２の取付け高さ及び向きを一定にすることができ、各取付金具２ごとの位置調整を行う必要がない。また、跨嵌部２２，２２が円弧状嵌合部２２ａ，２２ａを有するから、この跨嵌部２２，２２が横枠材ｂに的確に嵌合して、取付金具２の取付けの向きが一層確実に決まると共に、取付金具２がガタつくことなく一層安定状態に取り付けられる。
【００３４】
また、上記のようにヒンジ１３を挟んで両腕板１２，１２の一端側と他端側とが交互に開閉するように構成し、両腕板１２，１２の一端側を金具固定部Ｘ、他端側を付帯枠組仮設物取付部Ｙとしているから、取付金具２を枠組足場Ｗの縦枠材ａと横枠材ｂとの交差部に取り付ける際して、金具固定部Ｘ側を開口させることによって、掴持腕部２１、２１と跨嵌部２２，２２とを縦枠材ａと横枠材ｂとに対して容易迅速に嵌め込むことができる。
【００３５】
更に、荷受けステージＳをこの取付金具２に取り付けるに際に、各梁枠３の基端部に設けた支持ピン２８が各取付金具２のピン掛止用溝１８に掛止されるようになっているから、この支持ピン２８がピン掛止用溝１８に掛止されている限り、ボルト取付板部１７，１７側のボルト１６の取り付けが容易となるだけでなく、荷受けステージＳの取付け後に何からの原因で金具固定部Ｘ側のボルト１５やボルト取付板部１７，１７側のボルト１６が緩んだり、あるいは脱落するようなことがあっても、金具固定部Ｘ側及び荷受けステージ取付部Ｙ側のいずれも開口することがなく、きわめて安全である。
【００３６】
【発明の効果】
請求項１に係る発明の枠組足場用取付金具によれば、枠組足場の縦枠材と横枠材との交差部において横枠材上に支持されると共に当該横枠材の上位側で縦枠材を掴持する金具固定部と、付帯枠組み仮設物の一端側所要部を取り付ける付帯枠組み仮設物取付部とからなるため、金具固定部を横枠材上に支持させて当該横枠材の上位側で縦枠材を掴持するだけで、取付金具の取付位置の高さが決まり、従って高さ位置の調整をする必要がなく、位置決め作業が容易となり、また付帯枠組み仮設物取付部には付帯枠組み仮設物の一端側所要部を取り付けるだけでよいから、取付作業を簡単容易に行うことができる。そして特に、金具固定部が枠組足場の縦枠材を掴持した状態で横枠材上に支持されるから、取付位置が上下方向にずれることがない。
【００３７】
また本発明によれば、金具固定部の両掴持腕部により枠組足場の縦枠材を掴持してボルトで締結すると共に、枠組足場の横枠材上に両跨嵌部を跨嵌させることによって、取付金具の取付高さ位置が一定に決まると共に、取付けの向きが一定に決まる、即ち取付金具の荷受けステージ取付部が常に横枠材の長手方向に向くように位置決めされる。このため、複数個の取付金具を使用する場合に、各取付金具の取付け高さ及び向きを一定にすることができ、各取付金具ごとの位置調整を行う必要がなく、取り付け作業が非常に簡単容易となる。
【００３８】

[0024]
Once the load receiving stage S is formed as described above, although not shown in the figure, the rope R is hung on the four corners of the load receiving stage S, and the stage S is suspended by, for example, about 1.8 m with a crane. Then, the free end side of the diagonal member 9 folded along each beam frame 3 is pulled down, and the above-described procedure is performed between the free end portion of the diagonal member 9 and the base end portion of each beam frame 3. Attach both ends of the hanger 10 with
[0025]
On the other hand, six attachment brackets 2 of three upper stages and three lower stages are respectively attached to the stage attachment positions of the frame scaffold W (see FIG. 1). When mounting the mounting bracket 2, the two bolts 15 and 16 to be mounted on each mounting bracket 2 are removed in advance, and both arm plates 12 and 12 are pivoted about the hinge 13 to fix the mounting bracket. X is opened as shown by the phantom line in FIG. 13A, and the holding arm portions 21, 21 of the opened metal fixture fixing portion X are connected to the vertical frame material of the frame scaffold W via the fitting portions 21a, 21a. As shown in FIGS. 12 and 13, the straddle fitting portions 22 and 22 are straddled on the horizontal frame material b of the frame scaffold W, and then the bracket fixing portion X is closed. The bolt 15 on the metal fixture fixing part X side is inserted between both arm plates 12 and 12, the nut 15 a is tightened and the vertical frame material a is held by the holding arm parts 21 and 21, and thus the vertical frame material of the frame scaffold W The mounting bracket 2 is mounted and fixed at the intersection of a and the horizontal frame material b. At this time, as shown in FIGS. 13A and 13B, since the arc-shaped fitting portions 22a and 22a of the straddle fitting portions 22 and 22 are fitted to the upper surface side of the horizontal frame material b, the mounting bracket 2 is determined in a predetermined direction, that is, the load receiving stage mounting portion Y of the mounting bracket 2 is positioned so as to face the longitudinal direction of the horizontal frame member b.
[0026]
After mounting and fixing the six mounting brackets 2 to the stage mounting position of the frame scaffold W as described above, the load receiving stage S is lifted by a crane (not shown) and moved to the stage mounting position of the frame scaffold W. The base end side vertical frame member 23 of each beam frame 3 of the load receiving stage S is connected to the bolt mounting plate portion in which the load receiving stage mounting portion Y of each of the upper mounting brackets 2 of the six mounting brackets 2 is opened. 17 and 17, and the support pin 28 attached to the upper end portion of the base end side vertical frame member 23 is hooked in the pin hooking grooves 18 and 18 of the bolt mounting plate portions 17 and 17, and The arcuate engaging portion 27a of the engaging member 27 attached to the lower side of the base end side vertical frame member 23 is brought into contact with and engaged with the vertical frame member a of the frame scaffold W and is pivotally attached to each beam frame 3. The lower end of the diagonal member 9 is received by the three lower mounting brackets 2. Inserting between the bolt mounting plate portion 17 which is opened in the stage mounting portion Y. In this state, the load receiving stage S is hooked on the three upper mounting brackets 2 via the support pins 28 of the three beam frames 3 and loaded, and the base ends of the beam frames 3 are also supported. Since the engaging member 27 attached to the lower side of the side vertical frame member 23 is in contact with and engaged with the vertical frame member a of the frame scaffold W, the load receiving stage S can be maintained in a stable state.
[0027]
Thereafter, the bolt 16 on the load receiving stage mounting portion Y side of each of the three upper mounting brackets 2 is connected to the base end side of the beam frame 3 from the bolt insertion holes 19, 19 or 20, 20 of the bolt mounting plate portions 17, 17. The bolts 16 are inserted through the bolt insertion holes 29 and 30 provided in the vertical frame member 23, and the bolts 16 on the load receiving stage mounting portion Y side of the three mounting brackets 2 on the lower stage side are connected to the bolt mounting plate portions 17 and 17. The bolt insertion holes 19, 19 or 20, 20 may be inserted through bolt insertion holes 48 (see FIG. 7) provided at the lower end portion of the diagonal member 9, and the nut 16 a of each bolt 16 may be tightened. Each beam frame 3 of the stage S can be securely fixed to the upper and lower mounting brackets 2. In addition, what is necessary is just to fix the base end side of the upper handrail frame 40 which forms each side part handrail 5 to the vertical frame material a of the frame scaffold W with the pipe clamp 42.
[0028]
The baseboards 11 attached to the lower portions of the side handrail 5 and the front handrail 8 of the load receiving stage S may be attached when framing the load receiving stage S on the ground, or each beam frame 3 is attached to each After being attached and fixed to the metal fitting 2, it may be attached on the scaffolding plate 4 of the stage S.
[0029]
As described above, the load receiving stage S is temporarily installed at the required height position on the outer side of the frame scaffold W. However, the frame scaffold becomes higher due to the progress of the building work, and the load receiving stage S is changed to the one step height side. Sometimes, the bolt 16 on the load receiving stage mounting portion Y side of each mounting bracket 2 is removed, while the mounting bracket 2 is mounted at a predetermined replacement position of the frame scaffold W, and the load receiving stage S is lifted with a crane. What is necessary is just to attach the one end side of this stage S to each attachment bracket 2 in the said replacement position in the same way as the above.
[0030]
As described above, in the temporary construction method of the load receiving stage S as described with reference to the drawings, the load receiving stage S is formed in advance on the ground, and the frame receiving stage S is lifted by a crane and attached to the stage mounting position of the frame scaffold W. Since one end side of the load receiving stage S is attached to each mounting bracket 2, temporary work can be easily and quickly performed, work efficiency can be greatly improved, and the components of the stage S and further the workers Is less likely to fall, and work safety can be ensured. In particular, the frame work scaffold is raised by the progress of the building work, and the replacement work can be easily performed when the load receiving stage S is changed to the one-step height side.
[0031]
In order to frame the load receiving stage S on the ground, a plurality of beam frames 3 are arranged at predetermined intervals, a scaffolding plate 4 is mounted thereon, and side rails 5 are attached to the beam frames 3 on both ends. At the same time, a front handrail 8 is attached to the front end side of the beam frame 3, and the load receiving stage S is formed by pivotally attaching the upper end portion of the diagonal member 9 to the front end portion of each beam frame 3. In this state, the suspension member 10 is attached between the other end portion of each diagonal member 9 and the base end portion of each beam frame 3, and then the base end portion of each beam frame 3 and the lower end portion of each diagonal member 9 are connected. Since it is attached to the mounting bracket 2 on the side of the frame scaffold W, the number of components of the load receiving stage S is small, the number of places where bolt tightening is required is remarkably reduced, and the assembly of the stage S becomes very simple. .
[0032]
The mounting bracket 2 for attaching the load receiving stage S to the frame scaffold W is supported on the horizontal frame material b at the intersection of the vertical frame material a and the horizontal frame material b of the frame scaffold W and the horizontal frame. Since it is composed of a metal fixture fixing portion X that holds the vertical frame material a on the upper side of the material b, and a load receiving stage mounting portion Y that attaches the base end side vertical frame material 23 or the diagonal material 9 of the beam frame 3 in the load receiving stage S. The height of the mounting position of the mounting bracket 2 is determined by simply supporting the bracket fixing portion X on the horizontal frame member b and holding the vertical frame member a on the upper side of the horizontal frame member b. There is no need to adjust the position, the positioning work is facilitated, and it is only necessary to attach the base end side vertical frame member 23 or the diagonal member 9 of the beam frame 3 in the load receiving stage S to the load receiving stage mounting portion Y. Can be done easily and easily. In addition, since the bracket fixing portion X is supported on the horizontal frame material b in a state where the vertical frame material a is gripped, the mounting position is stable without shifting up and down.
