Description

【０００１】
【発明の属する技術分野】
本発明は、建築現場等で仮設される足場板に、その側縁部に沿って取り付けられる足場板用幅木に関するものである。
【０００２】
【従来の技術及びその課題】
建築現場等における足場板上での高所作業では、作業者の手にしたボルト・ナット、金具類等の種々の施工用部品や工具類、足元に置いた各種資材や用具等を誤って落下させ、事故につながるという危険性が常に付きまとう。そこで、安全対策として、足場板の側縁部に添って幅木を取り付けることが行われているが、従来、足場板用幅木を足場板に取り付けるにあたって、足場板の幅木取付部位にボルト孔等を開けるなど足場板側に何らかの加工を施す必要があるため、在来の足場板をそのまま使用できない難点があり、また足場板用幅木の構成が複雑で、足場板への取り付けに手間がかかるという問題があった。
【０００３】
一方、足場板１の取付ピッチＬａ（図７の（Ａ）参照）は足場板メーカーの各社共に殆ど一定であるが、足場板本体１ａの面板長さＬｂ（図７の（Ａ）参照）は各社違うため、幅木を足場板に取り付けた時に、幅木がガタついたり、ずれたりするという問題もあった。
【０００４】
本発明は、足場板側に何の加工も施す必要がなく、在来の足場板をそのまま使用できると共に、足場板への取付け及び取外しが簡単容易に行え、しかも足場板のメーカーによって幅木がガタついたり、ずれたりすることのないようにした足場板用幅木を提供することを目的とする。
【０００５】
【課題を解決するための手段】
請求項１に係る発明の足場板用幅木は、足場板１の側縁部５上に起立姿勢に載置される幅木本体４を有し、この幅木本体４の前後各端部に、端部キャップ１２と、足場板１の外側端面６に支持されるアウトガイド１０と、足場用建枠の横架材２に掛合されるキャッチガイド１３と、このキャッチガイド１３を前記横架材２に掛合させてロックするロック手段１４とを設け、前記キャッチガイド１３は、端部キャップ１２に垂下状態で前後方向揺動自在に枢支されて、その下端掛合部１３ａが足場板係止用フック８の内側面近接位置で足場板１の前後端面７と足場用建枠の横架材２との間に突入し、ロック手段１４により横架材２に掛合ロックされるようになっていることを特徴とする。
【０００６】
請求項２は、請求項１に記載の足場板用幅木において、ロック手段１４は、キャッチガイド１３の枢着部１５より下方位置でキャッチガイド１３に対しその後方より進退移動自在に端部キャップ１２に螺装されたロックボルト１６からなり、このロックボルト１６を締め込むことにより、キャッチガイド１３を前方へ押動して、その下端掛合部１３ａを足場用建枠の横架材２に掛合させてロックし、ロックボルト１６を緩めることによりキャッチガイド１３をロック解除させるようになっていることを特徴とする。
【０００７】
請求項３は、請求項１に記載の足場板用幅木において、ロック手段１４は、キャッチガイド１３の枢着部１５より下方位置で係止部材１３に対しその後方より進退移動自在に端部キャップ１２に取り付けられるロックピン２１と、キャッチガイド１３が常時ロック解除状態となるようにロックピン２１を付勢するバネ２２とからなり、ロックピン２１は後端部に折曲部２１ａを有し、このロックピン２１をバネ２２の付勢力に抗し前方へ押動してキャッチガイド１３を足場用建枠の横架材２に掛合させた後、ロックピン２１を所要角度回転させて、その後端折曲部２１ａをストッパー２３に係止させることにより、キャッチガイド１３をロックするようになっていることを特徴とする。
【０００８】
請求項４は、請求項１〜３の何れかに記載の足場板用幅木において、幅木本体４の一端側端部キャップ１２に幅木連結用フックレバー１８の一端部を枢着し、幅木本体４の他端側端部キャップ１２には前記フックレバー１８の遊端部に形成されたフック１８ａを受けるフック受け１９を設けてなることを特徴とする。
【０００９】
【発明の実施の形態】
本発明に係る足場板用幅木について図面を参照して説明すると、図１の（Ａ）は、対向する一対の足場用建枠（図示省略）の横架材２，２間に並列状態に架け渡された複数枚の足場板１の両側縁部に、足場板用幅木３，３を足場板１の上側から落とし込んで取り付けようとしている状態を示し、（Ｂ）は足場板用幅木３を取り付けた状態を示す。また、図２の（Ａ）は足場板用幅木３をその内側面側から見た側面図、（Ｂ）は幅木３の平面図であり、図３の（Ａ）は図２の（Ａ）の矢印Ｘで囲まれた部分の拡大図、（Ｂ）は同部分の平面図、（Ｃ）は同部分の端面図である。図４は幅木３を足場板１に取り付けようとしている状態を示す斜視図、図５は幅木３を足場板１に取り付けた状態の斜視図、図６は幅木３の取付状態を図５の矢印Ｙ方向から見た側面図である。
【００１０】
足場板１には前後各端面７の左右両端部に足場板係止用フック８，８が突設され、各端面７の両係止用フック８，８は足場用建枠の横架材２に係止されるようになっており、この状態を図１の（Ａ），（Ｂ）及び図７の（Ａ）に示す。
【００１１】
本発明に係る足場板用幅木３は、図１の（Ａ）及び（Ｂ）に示すように足場板１の側縁部５上に起立姿勢で載置される幅木本体４を有している。そして、この幅木本体４の前各端部には、端部キャップ１２と、幅木本体４が足場板１の側縁部５上に起立姿勢に載置された状態で足場板１の外側端面６に当接支持されるアウトガイド１０と、足場用建枠の横架材２に掛合されるキャッチガイド１３と、このキャッチガイド１３を足場用建枠の横架材２に掛合させてロックするロック手段１４とが設けられており、キャッチガイド１３は、端部キャップ１２に垂下状態で前後方向揺動自在に枢支されて、その下端掛合部１３ａが足場板係止用フック８の内側面８ａに近接した位置で足場板１の前後端面７と足場用建枠の横架材２との間に突入し、ロック手段１４によって横架材２に掛合ロックされるようになっている。
【００１２】
アウトガイド１０は、図３〜図６に示すように、溝形鋼材からなるもので、溝形鋼材の溝部を外側に向けてその背面を幅木本体４の外側面に当接させると共に、溝形鋼材の下端部を幅木本体４の下端から所要長さ突出させた状態でリベット等により固着し、幅木本体４下端からの突出部分の背面側を、足場板１の外側端面６に当接支持される支持面ａとしている。
【００１３】
端部キャップ１２は、幅木本体４の前後各端部に取り付け固定されるもので、幅木本体４の端面の内側端部から突出する断面略Ｕ字状の突出部１２ａを有し、このＵ字状突出部１２ａの先端部下面ｂが、幅木３の取付時に足場用建枠の横架材２上に当たって位置決めされるようになっている。また、Ｕ字状突出部１２ａの両側部下端から下向きに突出する突片１２ｂ，１２ｂが突設されており、両突片１２ｂ，１２ｂは、幅木３の取付時に足場板１の前後端面７と足場用建枠の横架材２との間に突入するようになっている。
【００１４】
キャッチガイド１３は、端部キャップ１２のＵ字状突出部１２ａ内に挿入されて、その上端部が枢支軸１５により垂下状態で前後方向に揺動自在に枢支され、その下端掛合部１３ａが足場板１の前後端面７と足場用建枠の横架材２との間に前後移動自在に突入されて、当該下端掛合部１３ａと前記アウトガイド１０とによって足場板係止用フック８を挟むような形となる。このキャッチガイド１３の下端掛合部１３ａの先端面は、足場用建枠の横架材２に掛合する掛合凹部ｃを形成している。この場合、キャッチガイド１３は、図７の（Ｂ）の左側に示すように、ロック手段１４によってロックされていない状態では、その下端掛合部１３ａが足場板１の前後端面７と足場用建枠の横架材２との中間に位置して足場用建枠の横架材２に係合しないように、枢支軸１５によって端部キャップ１２に枢着されている。
【００１５】
要するに、このキャッチガイド１３は、振り子のように、上端部の枢支軸１５を揺動支点として前後方向揺動自在に垂下されていて、足場板１に取り付けた時に、その下端掛合部１３ａが、足場板係止用フック８の内側面近接位置で足場板１の前後端面７と足場用建枠の横架材２との中間位置に突入した状態となり（図７の（Ｂ）の左側部分参照）、そしてロック手段１４をロック操作することによって、下端掛合部１３ａの掛合凹部ｃが、図７の（Ｂ）の右側部分に示すように横架材２に掛合してロック状態となる。また、ロック手段１４をロック解除操作すれば、キャッチガイド１３がその自重により元の位置に復帰して、下端掛合部１３ａの掛合凹部ｃが横架材２から離脱し、図７の（Ｂ）の左側部分に示すようなロック解除状態となる。尚、枢支軸１５は、ボルト・ナットからなる。
【００１６】
上記ロック手段１４は、キャッチガイド１３の枢支軸１５（枢着部）より下方位置でキャッチガイド１３の後端凹部１３ｂに対し進退移動するように端部キャップ１２のＵ字状突出部１２ａ内に螺装されたロックボルト１６からなる。即ち、図３から分かるように、端部キャップ１２のＵ字状突出部１２ａにはキャッチガイド１３の後端凹部１３ｂの後方位置にナット１７が取り付けてあって、このナット１７に、幅木本体４の内部からＵ字状突出部１２ａの内部にって挿入されたロックボルト１６が螺入され、このボルト先端部がキャッチガイド１３の後端凹部１３ｂに突入している。尚、ナット１７は、端部キャップ１２のＵ字状突出部１２ａに貫設された開口部Ｏより挿入されて溶接により固着されている。
【００１７】
このロック手段１４によれば、ロックボルト１６をねじ込み方向に回すことにより、ボルト先端部がキャッチガイド１３を押動して、その下端掛合部１３ａの掛合用凹部ｃが足場用建枠の横架材２に掛合してロックされる。この状態を図７の（Ｂ）の右側に示す。また、ロックボルト１６を緩めると、キャッチガイド１３が自重により元の位置に復帰して、キャッチガイド下端部１３ａの係止用凹部ｃが足場用建枠の横架材２から離脱して、ロック解除状態となり、この状態を図７の（Ｂ）の左側に示す。このロックボルト１６からなるロック手段１４は、構成がきわめて簡単であるから、製作が容易となる。
【００１８】
図２及び図８に示すように、各幅木３には、幅木本体４の一端側端部キャップ１２に、幅木連結用フックレバー１８の一端部が枢着され、幅木本体４の他端側端部キャップ１２には、フックレバー１８の遊端部に形成されたフック１８ａを受けるフック受け１９が設けられている。フックレバー１８の一端部は、端部キャップ１２のＵ字状突出部１２ａの外側面にボルト２０により枢着されている。フック受け１９は、キャッチガイド１３を端部キャップ１２のＵ字状突出部１２ａに枢着している枢支軸１５のボルト首下部に形成される（図３の（Ｃ）参照）もので、前記フックレバー１８のフック１８ａが係嵌されるようになっている。図８は、隣合う一方の幅木３と他方の幅木３とが、フックレバー１８とフック受け１９とによって連結された状態を示す。このように隣合う幅木３，３の端部どうしをフックレバー１８とフック受け１９とで連結することにより、隣合う幅木３，３どうしを一体化して、各幅木３の揺れやガタつき等をなくすると共に、足場板１に対する各幅木３の取付状態をより強固なものとすることができる。
【００１９】
以上説明したように構成される足場板用幅木３を足場板１に取り付けるには、図１、図３及び図４に示すように、幅木３を足場板１の側縁部５の上方に持ち来たし、この足場板側縁部５の上方から幅木３をそのまま降ろして、幅木本体４を足場板１の側縁部５上に載置して、幅木本体４の前後両端部に夫々設けてあるアウトガイド１０の支持面ａを足場板１の外側端面６に当接支持させると共に、キャッチガイド１３の下端掛合部１３ａを足場板１の前後端面７と足場用建枠の横架材２との間に突入させる。この時、端部キャップ１２の先端部下面ｂが足場用建枠の横架材２上に乗って位置決めされるようになっている。この後、ロック手段１４のロックボルト１６を締め込んで、キャッチガイド１３の下端掛合部１３ａを横架材２に掛合すると共に、この掛合状態にロックする。
【００２０】
上記のように幅木本体４を足場板１の側縁部５上に載せて、アウトガイド１０の支持面ａを足場板１の外側端面６に当接支持させ、キャッチガイド１３の下端掛合部１３ａを足場板１の前後端面７と足場用建枠の横架材２との間に突入させることによって、幅木本体４の左右方向の移動及び倒れが阻止される。これは、図３の（Ｂ）から分かるように、アウトガイド１０とキャッチガイド１３の下端掛合部１３ａによって足場板１の係止用フック８を挟む状態となるからである。そしてまた、キャッチガイド１３の下端掛合部１３ａを足場用建枠の横架材２に掛合することによって、幅木本体４の前後方向の移動が阻止され、これによって幅木本体４は、足場板１の側縁部５上で起立姿勢に保持固定される。また、この幅木３を取り外すときは、幅木本体４をそのまま持ち上げるだけで、簡単容易に足場板１から取り外すことができる。
【００２１】
上記キャッチガイド１３の作用について、図７を参照して更に説明すると、この図７の（Ｂ）では、右側のキャッチガイド１３がロック状態にあって、左側のキャッチガイド１３は非ロック状態となっているが、この左側のキャッチガイド１３もロック状態にすることによって、幅木本体４の前後両端側のキャッチガイド１３，１３が両足場用建枠の横架材２，２に掛合して突っ張った状態となるため、幅木本体４の前後方向の移動が完全に阻止される。
【００２２】
しかも、この場合、キャッチガイド１３は、端部キャップ１２に垂下状態で前後方向揺動自在に枢支されて、その下端掛合部１３ａが足場板１の前後端面７と足場用建枠の横架材２との間に突入した位置で前後に移動可能となっているから、この位置でキャッチガイド１３をロック操作することにより、下端掛合部１３ａの掛合用凹部ｃが横架材２に掛合した位置で幅木本体４の前後方向の移動を完全に阻止することができ、従って図７の（Ａ）に示す足場板本体１ａの面板長さＬｂが各メーカーによって違っていても、幅木３を足場板１に取り付けた時に、幅木３がその長手方向にガタついたり、ずれたりすることがない。また、ロック手段１４をロック解除操作すれば、つまりロックボルト１６を緩めれば、キャッチガイド１３は自重によって元の位置に自動復帰することができる。
【００２３】
図９〜図１２は、ロック手段１４の他の実施形態を示している。図９の（Ａ）は幅木３の一端部をその内側面側から見た側面図、（Ｂ）は（Ａ）の左端面図、（Ｃ）は（Ａ）の平面図であり、図１０は図４と同様な斜視図で、幅木３を足場板１に取り付けようとしている状態を示し、図１１は図５と同様な斜視図で、幅木３を足場板１に取り付けた状態を示している。
【００２４】
このロック手段１４は、キャッチガイド１３の枢着部１５よりも下方位置でキャッチガイド１３の後端凹部１３ｂに対し進退移動自在に端部キャップ１２のＵ字状突出部１２ａに取り付けられるロックピン２１と、キャッチガイド１３が常時ロック解除状態となるようにロックピン２１を付勢するコイルバネ２２とからなり、ロックピン２１はその後端部に折曲部２１ａを有し、このロックピン２１をコイルバネ２２の付勢力に抗し前方へ押動してキャッチガイド１３を足場用建枠（図示省略）の横架材２に掛合させた後、このロックピン２１を約９０度回転させて、後端折曲部２１を幅木本体４側に設けたストッパー２３に係止させることにより、キャッチガイド１３を横架材２に掛合させた位置にロックするようになっている。
【００２５】
ロックピン２１は、幅木本体４の内側面に取り付けられたコ字状枠のピン受け台２４の両側板部２４ａ，２４ａに挿通支持されていて、コイルバネ２２により常時後方側へ付勢されてロック解除状態となっているが、このピン２１の先端部は常時キャッチガイド１３の後端凹部１３ｂに突入係合している。また、このロックピン２１は、コイルバネ２２の付勢力に抗して前方へ押し込んだ状態で、約９０度回転させて後端折曲部２１をストッパー２３に係止させることによって、キャッチガイド１３を横架材２に掛合させた位置にロックすることができる。
【００２６】
このロックピン２１からなるロック手段１４によれば、ロックピン２１をコイルバネ２２の付勢力に抗し前方へ押して所要角度回転させて後端折曲部２１をストッパー２３に係止させることにより、キャッチガイド１３をロックでき、またロック解除するには後端折曲部２１をストッパー２３から外すだけでよいから、ロック操作及びロック解除操作を迅速に行うことができる。
【００２７】
【発明の効果】
請求項１に係る発明の幅木によれば、幅木を足場板に取り付けるにあたって、幅木本体を足場板の側縁部上に載せて、アウトガイドの支持面を足場板の外側端面に当接支持させると共に、キャッチガイドの下端掛合部を足場板の前後端面と足場用建枠の横架材との間に突入させることにより、アウトガイドとキャッチガイドの下端掛合部によって足場板の係止用フックを挟む状態となって、幅木本体の左右方向の移動及び倒れを阻止でき、そしてロック手段をロック操作することによって幅木本体の長手方向の移動を阻止できる。また、幅木を取り外すには、ロック手段を解除操作して幅木をそのまま持ち上げるだけでよいから、幅木の取付け及び取外しが極めて簡単容易となる。
【００２８】
また、この発明の幅木によれば、キャッチガイドは、端部キャップに垂下状態で前後方向揺動自在に枢支されて、下端掛合部が足場板の前後端面と足場用建枠の横架材との間に突入した位置で前後に移動可能となっているから、この位置でキャッチガイドをロック操作すれば、下端掛合部が横架材に掛合した位置で幅木本体の前後方向の移動を完全に阻止することができ、従って足場板本体の面板長さが各メーカーによって違っていても、幅木を足場板に取り付けた時に、幅木がその長手方向にガタついたり、ずれたりすることがない。更に、この発明の幅木は、足場板側には幅木取付のための何の加工も施す必要がないため、在来の足場板をそのまま使用できる。
【００２９】
請求項２に記載のように、ロック手段がロックボルトからなるものによれば、構成が簡単であるから、製作が容易となる。
【００３０】
請求項３に記載のように、ロック手段がロックピンからなるものによれば、ロック操作及びロック解除操作を迅速容易に行うことができる。
【００３１】
請求項４に記載のように、幅木本体の一端側端部キャップに幅木連結用フックレバーの一端部を枢着し、幅木本体の他端側端部キャップにフックレバーの遊端部のフックを受けるフック受けを設けているから、隣合う幅木の端部どうしをフックレバーとフック受けとで連結することにより、隣合う幅木どうしを一体化して、各幅木の揺れやガタつき等をなくすると共に、足場板に対する各幅木の取付状態をより強固なものとすることができる。
