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物品や工具類、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、従来では、足場板の側縁部に、別の足場板や施工現場にある適当な帯板材を堰板状に立てた形で針金やワイヤー等で縛り付けて固定することにより、物品が足場板上から落下するを防止する方法が採られている。
【０００３】
然るに、このような従来の落下防止手段では、各足場板毎に別の足場板や帯板材を取り付け、また施工後に取り外すための作業に多大な労力と時間を費やす上、取付状態の安定性及び信頼性も不充分であるという問題があった。
【０００４】
本発明は、上述の事情に鑑み、足場板の側縁部に取り付けて物品の足場板上から外側への落下を防止する足場板用幅木として、対策を必要とする足場板に対しきわめて簡単な操作で取付け及び取外しできると共に、構造的にも簡素で安価に製作できる幅木を提供することを目的としている。
【０００５】
【課題を解決するための手段】
請求項１に係る発明は、足場板１の側縁部に沿って取り付けられる幅木３であって、幅木本体４の外面側に、複数のスライドロック金具５が、夫々ロックボルト１０の回動操作によって幅木本体４に対し上下にスライドするように取り付けられ、各スライドロック金具５は、幅木本体４よりも下方に突出する下部に幅木本体４の下面と対向するロック片６を備え、このロック片６と幅木本体４の下面との間に足場板１の側縁部を嵌め込んだ状態で、スライドロック金具５が上方へスライドするようにロックボルト１０を締め付けることによって、幅木本体４が垂直姿勢に固定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、幅木本体４の下面に、足場板１の側縁部上面に形成された滑り止め用溝部１６に係合する突条部１３が条設されていることを特徴とする。
【０００７】
請求項３は、請求項１又は２に記載の足場板用幅木において、幅木本体４の端部には他の幅木本体４の対向端部と連結用ピン１９によって連結されるようになっていることを特徴とする。
【０００８】
【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３，３が取り付けられた状態を示す。また、図２の（Ａ）は足場板用幅木３をその外面側から見た正面図、（Ｂ）は同幅木３の平面図、図３の（Ａ）は図２（Ａ）の一部拡大図、（Ｂ）は図２（Ｂ）の一部拡大図、（Ｃ）は（Ａ）のＸ−Ｘ線断面図、（Ｄ）は（Ａ）に示す幅木３の右側面である。
【０００９】
これら図１〜図３と図４を参照して分かるように、本発明に係る足場板用幅木３は、内側壁４ａと、上壁部４ｂと、下壁部４ｃと、上壁部４ｂ及び下壁部４ｃの夫々外端縁から上下対向方向に突設された上下フランジ部４ｄ，４ｅとによって横断面略Ｃ字状に形成された幅木本体４を有する。幅木本体４の外面側には幅木長手方向両端部側２箇所に、スライドロック金具５，５が、夫々ロックボルト１０の回動操作によって幅木本体４に対し上下方向にスライドするように取り付けられ、各スライドロック金具５は、幅木本体４よりも下方に突出する下部に、幅木本体４の下端面と対向するロック片６を備えている。
【００１０】
上記スライドロック金具５の構造について図３及び図４を参照して詳しく説明すると、このスライドロック金具５が取り付けられる幅木本体４の両端部側には、左右縦枠７ａ，７ａと上下横枠７ｃ，ｄとからなる矩形枠状の補強枠７が上下フランジ部４ｄ，４ｅにブラインドリベットＲによって取り付けられると共に、この補強枠７を介して幅木本体４にスライドロック金具５が上下スライド自在に取り付けられる。
【００１１】
このスライドロック金具５は、図３の（Ｃ）及び図４の（Ａ）から分かるように、幅木本体４の内側壁４ａと補強枠７とに挟まれた状態で上下にスライドするコ字形ブロック８と、このコ字形ブロック８の背面側に一体に形成されていて、両側端面が補強枠７の両縦枠７ａ，７ａに挟まれた状態でコ字形ブロック８と共にスライドするＩ字形ブロック９と、このＩ字形ブロック９の下端部に、幅木本体４の下壁部４ｃ下面と対向するようにＩ字形ブロック９と直角に突設された前記ロック片６とからなる。
【００１２】
上記コ字形ブロック８には上部フランジ８ａに、ネジ孔１１が設けてあって、このネジ孔１１に、幅木本体４の上壁部４ｂのボルト挿通孔１２に通されたロックボルト１０のネジ部１０ａが螺合されており、ロックボルト１０の頭部１０ｂには操作ツマミ１０ｏが設けられている。従って、このロックボルト１０を、頭部１０ｂの操作ツマミ１０ｏを掴んで回動することによって、スライドロック金具５が幅木本体４に対し上下にスライドするようになっている。
【００１３】
このスライドロック金具５を幅木本体４に取り付けるには、スライドロック金具５の下端部分を図４の（Ａ）に実線で示す状態から同図の矢印線で示すように補強枠７内に挿入して同図の仮想線図示の状態とした後、補強枠７を幅木本体４の上下フランジ部４ｄ，４ｅにブラインドリベットＲでかしめて取付け固定し、その後ロックボルト１０を幅木本体上壁部４ｂのボルト挿通孔１２に挿通して、このボルト１０のネジ部１０ａを、コ字形ブロック８の上部フランジ８ａにあるネジ孔１１に螺入し、図４の（Ｂ）に示すような状態とする。
【００１４】
また図４の（Ａ）及び（Ｂ）に示すように、幅木本体４には下壁部４ｃの下面に、足場板１の側縁部上面に形成されている滑り止め用溝部１４に係合する突条部１３が条設されている。この突条部１３は、幅木３を垂直姿勢で足場板１の側縁部上面に取り付ける時に足場板１の側縁部上面に形成されている滑り止め用溝部１４に係合して、当該幅木３を取付位置に位置決めするものである。
【００１５】
足場板１には、図５に示すように、足場板本体１６の上面に、足場板長手方向に延びる複数本の滑り止め用溝部１４が条設されていると共に、多数の滑り止め用孔部１５が穿設されており、幅木本体４下面の突条部１３は、足場板本体１ａ上面の端にある滑り止め用溝部１４に係合するようになっている。また図５から分かるように、足場板本体１６の側縁部１６ａは断面Ｌ字状に形成されていて、幅木３を取り付ける際に、この断面Ｌ字状側縁部１６ａにスライドロック金具５のロック片６を含む下端部分が嵌合するようになっている。
【００１６】
図２及び図３に示すように、幅木本体４の両端部には夫々端部キャップ１７が取り付けられ、各端部キャップ１７にはピン挿入孔１８が幅木高さ方向に貫設され、一方側の端部キャップ１７には、倒Ｌ字状の連結用ピン１９が取り付けられていて、この連結用ピン１９の先端係止部１９ａを他の幅木３の幅木本体４の対向端部にあるピン挿入孔１８に係入することにより、当該他の幅木３と連結できるようになっている。この連結用ピン１９は、図３の（Ａ）に示すように、常時はコイルバネ２０によって、先端係止部１９ａが他の幅木３のピン挿入孔１８に係入し得る連結位置に付勢されている。従って、連結時には、連結用ピン１９をコイルバネ２０の付勢力に抗して図３の（Ａ）に示す連結位置から引き上げて、非連結位置とした状態で、連設すべき他の幅木３のピン挿入孔１８に係入させるようになっている。
【００１７】
以上説明したような構成を有する幅木３を足場板１に取り付けるに際しては、先ず、図５の▲１▼及び▲２▼に示すように、足場板１の側縁部（詳しくは、足場板本体１６の側縁部１６ａ）に、幅木本体４よりも下方に突出するロック片６を含むスライドロック金具５の下部側を嵌め込んだ状態とする。この時、幅木本体４の下面と、これに対向するスライドロック金具５のロック片６との間隔Ｓは、幅木本体４の厚さＴよりも広くなっている。
【００１８】
しかして、図５の▲２▼に示すような状態において、幅木本体４下面の突条部１３を、足場板本体１６の側縁部１６ａ上面にある滑り止め用溝部１４に係合させ、幅木３を足場板１の側縁部上の所定位置に位置決めする。こうして幅木３を足場板１に対し位置決めした後、ロックボルト１０を、その頭部１０ｂの操作ツマミ１０ｏを掴んで回動して締め込むと、スライドロック金具５が幅木本体４に対し上方向にスライドして幅木本体４の下面とスライドロック金具５のロック片６との間隔Ｓが狭まり、最終的に図６の▲１▼に示すように、幅木本体４側の突条部１３が足場板１側の滑り止め用溝部１４に係合すると共に、幅木本体４の下面が足場板１の側縁部上面に当接し且つスライドロック金具５のＩ字形ブロック９下部及びロック片６が足場板本体１６の側縁部１６ａに嵌合した状態で、幅木本体４が足場板本体１６の側縁部１６ａ上面に垂直姿勢に固定される。
【００１９】
この後、図６の▲２▼に示すように、幅木本体４の一端部側の端部キャップ１７に取り付けてある連結用ピン１９の先端係止部１９ａを、隣合う他の幅木３の幅木本体４の対向端部の端部キャップ１７のピン挿入孔１８に係入して、双方の幅木本体４どうしを連結する。
【００２０】
上記のようにして足場板本体１６の側縁部１６ａ上面に固定した幅木３を足場板１から取り外す時は、ロックボルト１０を取付時と反対方向に回転させると、スライドロック金具５が幅木本体４に対し下方向にスライドして、幅木本体４の下面とスライドロック金具５のロック片６との間隔Ｓが図５の▲２▼のように広がるから、この状態でスライドロック金具５を足場板本体１６の側縁部１６ａから簡単に取り外すことができる。
【００２１】
以上のような実施形態の説明から明らかなように、この幅木３は、ロックボルト１０を緩めて、幅木本体４の下面と、これに対向するスライドロック金具５のロック片６との間隔Ｓを幅木本体４の厚さＴよりも広くした状態で、幅木本体４よりも下方に突出するロック片６を含むスライドロック金具５の下部側を足場板１の側縁部に嵌め込んだ後、ロックボルト１０を締め込むだけの簡単な操作で、幅木本体４が足場板本体１６の側縁部１６ａ上面に垂直姿勢に取付け固定することができる。また、この幅木３の取付けに際しては、幅木本体４の下面に条設した突条部１３を、足場板本体１６の側縁部１６ａ上面にある滑り止め用溝部１４に係合して、幅木本体４を足場板１の側縁部上の所定位置に位置決めすることにより、幅木本体４を、位置ずれすることなく足場板１の側縁部上に安定状態に取り付け固定することができる。
【００２２】
【発明の効果】
請求項１に係る発明によれば、幅木の取付けにあたっては、ロックボルトを緩めて幅木本体の下面とロック片との間隔を幅木本体の厚さより広くした状態で、幅木本体よりも下方に突出するロック片を含むスライドロック金具の下部側を足場板の側縁部に嵌め込んだ後、ロックボルトを締め込むようにすればよいから、既設の足場板に対し幅木を簡単に取りつけることができ、またその幅木の取外しも簡単である。また構造も簡素であるため安価に製作可能となる。
【００２３】
請求項２に係る発明によれば、幅木本体の下面に、足場板の側縁部上面に設けてある滑り止め用溝部に係合する突条部が条設されているから、幅木の取付けにあたって、幅木本体側の突条部を足場板側の滑り止め用溝部に係合させることにより、幅木本体を、位置ずれすることなく足場板の側縁部上に安定状態に取り付け固定することができる。
【００２４】
請求項３に係る発明によれば、幅木本体の端部を他の幅木本体の対向端部と連結用ピンによって連結できるようになっているから、幅木どうしを連結することによって、各幅木をより安定に取付けできると共に、隣合う幅木の端部間に隙間ができるのを防止できる。
