Description

【０００１】
【発明の属する技術分野】
本発明は、クランプ装置に関するもので、特に、上下で互いに交差する一対のＨ型鋼同士を固定する際に用いるものに関する。
【０００２】
【従来の技術】
床面上に機器を設置する際に、予め、床面に骨組み材として配設された型鋼、例えばＨ型鋼にその機器フレームの支柱体を支持させる必要がある。
【０００３】
ところで、機器フレームの支柱体をＨ型鋼に支持する際に、その設置レイアウトが変更になった場合、すなわち既に設置されているＨ型鋼に支持することができななくなった場合、新たに、現地にて別のＨ型鋼を設置する必要があり、しかも作業上、簡便な方法にて固定する必要がある。
【０００４】
従来、Ｈ型鋼同士を固定する装置としては、図１７に示すように、上下で互いに交差する一対のＨ型鋼５１，５２の各フランジ部５１ａ，５２ａにボルト５３，５４を介して係脱自在にされた一対のクランパ５５，５６が、一方に設けられた支持ピン５７に他方が揺動自在に設けられたものがある（例えば、特許文献１参照）。

【０００６】
【発明が解決しようとする課題】
ところで、上記従来のクランプ装置によると、一方のクランパ５５に形成された凹部５５ａ内に他方のクランパ５６を支持ピン５７により揺動自在に設けた構成は複雑であり製作コストが高くつくとともに、一対のクランパ５５，５６同士が揺動自在に設けられているため、両Ｈ型鋼５１，５２同士にずれが発生するおそれがあった。
【０００７】
そこで、本発明は、互いに交差された一対のＨ型鋼同士を固定する際に、製作コストが安価で且つ確実に固定し得るクランプ装置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】
上記課題を解決するために、本発明の請求項１に係るクランプ装置は、上下に重ねて且つ互いに交差するように配置された一対のＨ型鋼同士を固定するためのクランプ装置であって、
互いに表面同士が接触しているＨ型鋼のフランジ部の裏面に所定長さに亘って接触し得る接触面を有する長方形状の平板部、この平板部の一側縁側にフランジ部とほぼ同一高さでもって９０度曲げられた折曲部、およびこの折曲部の両端部に且つ当該折曲部と同一方向に突設された係合片からなる当接板と、
上記各当接板が、当接されるＨ型鋼と異なるＨ型鋼を跨ぐように井桁状に配置された状態で、それぞれの端部同士を連結する連結具とから構成し、
且つ上記各当接板の両端部に突設された係合片同士の間隔が、各当接板が井桁状に連結された状態において、一方のＨ型鋼のフランジ部に当接される当接板の両係合片により、他方のＨ型鋼のフランジ部に当接される一対の当接板を保持し得るように、当該両当接板の外縁間の距離に等しくなるようにしたものである。
【０００９】
このクランプ装置の構成によると、両端部に係合片がそれぞれ突設された４個の当接板を井桁状に配置して交差するＨ型鋼のフランジ部同士を挟持するとともに、それぞれに設けられた係合片同士により、当接板が互いにずれないようにしたので、非常に簡単且つ安価な構成にて、Ｈ型鋼同士を確実にクランプし得る。
【００１０】
また、請求項２に係るクランプ装置は、上下に重ねて且つ互いに９０度でもって交差するように配置された一対のＨ型鋼同士を固定するためのクランプ装置であって、
互いに接触しているＨ型鋼同士の両フランジ部の交差部分にこれら両Ｈ型鋼の軸心に対し４５度の角度でもって外嵌し得る４個の挟持体と、上記互いに接触しているフランジ部同士の交差部分に外嵌されてこれら両フランジ部同士を挟持する４個の挟持体を、互いにその位置がずれないように連結する索状体とから構成し、
さらに上記各挟持体を、両フランジ部を案内し得る凹状部がそれぞれ形成された一対の押え板と、これら一対の押え板同士を連結する連結具とから構成し、
且つ上記一対の各押え板に形成される凹状部の形状を、各フランジ部に４５度の角度でもって外嵌された際に、交差する各フランジ部に合致するように互いに対称となるようにしたものである。
【００１１】
このクランプ装置の構成によると、Ｈ型鋼の交差部分におけるフランジ部同士を４個の挟持体により挟持するとともにこれら４個の挟持体を索状体により互いに連結するようにしたので、やはり、非常に簡単且つ安価な構成にて、Ｈ型鋼同士を確実にクランプし得る。
【００１２】
また、請求項３に係るクランプ装置は、上下に重ねて且つ互いに交差するように配置された一対のＨ型鋼同士を固定するためのクランプ装置であって、
側面視がＣ字形状にされるとともにその両先端部にＨ型鋼のフランジ部の左右側縁部に係合し得る係合爪部が形成された一対の係合金具と、
上記一対の係合金具が一方のＨ型鋼のフランジ部の両側に配置されるとともにそれぞれの両係合爪部により他方のＨ型鋼のフランジ部に係合された状態で、各係合金具の中央に形成された凹状部に挿通可能にされてその一端側にて一方のＨ型鋼のフランジ部の裏面に当接されるとともに他端側に他方のＨ型鋼のフランジ部の表面を押圧し得るボルト材が螺挿された押え片とから構成したものである。
【００１３】
このクランプ装置の構成によると、例えば下側のＨ型鋼のフランジ部の両側に係合金具を配置するとともに、その両端部に形成された係合爪部を他方である上側のＨ型鋼のフランジ部の両側縁部に係合させた状態で、係合金具の凹状部に押え片を挿入させた後、ボルト材により当該係合金具を下側のＨ型鋼に付勢させるようにしたので、やはり、非常に簡単且つ安価な構成にて、Ｈ型鋼同士を確実にクランプし得る。
【００１４】
【発明の実施の形態】
以下、本発明の第１の実施の形態に係るクランプ装置を、図１〜図６に基づき説明する。
【００１５】
通常、機器、棚などを設置する際に、その支柱部材を、予め、床面上に所定方向で配設された強度部材（骨組み材）としてのＨ型鋼に支持させるようにしているが、その設置レイアウトがＨ型鋼の軸心に対して横方向（Ｈ型鋼の軸心と直交する方向）で変更になった場合、新たにＨ型鋼を既設のＨ型鋼上に且つ当該既設のＨ型鋼の軸心と直交する方向で配設する必要が生じる。
【００１６】
本発明に係るクランプ装置は、このような場合、すなわち既設のＨ型鋼上に新たなＨ型鋼を、互いに直交する（９０度でもって交差する）ように載置して固定する際に用いるものである。
【００１７】
図１〜図３に示すように、本第１の実施の形態に係るクランプ装置１は、上下に重ねて且つ互いに直交するように配置された一対のＨ型鋼２，３同士を固定するもので、互いに表面同士が接触しているＨ型鋼２，３のフランジ部２ａ，３ａの裏面に所定長さでもって当接し得るとともに両端部に相手方のＨ型鋼２，３側に突出する係合片４が設けられた４個の当接板５と、これら各当接板５が、当接されるＨ型鋼（２または３）と異なるＨ型鋼（３または２）を跨ぐように井桁状に配置された状態で、それぞれの端部同士を連結するボルト・ナット（連結具）６，７とから構成され、且つ上記各当接板５が井桁状に連結された状態においては、互いの当接板５が、それぞれ端部に突出された係合片４により、フランジ部２ａ，３ａから離間するのが（位置ずれが）防止されている。なお、各当接板５には、井桁状に配置された状態で、ボルト６を挿通するためのボルト穴（穴部）８が形成されている。
【００１８】
ここで、上記当接板５について、より具体的に説明する。
この当接板５は、図４〜図６に示すように、Ｈ型鋼のフランジ部の裏面に所定長さに亘って接触し得る接触面を有する長方形状の平板部５ａと、この平板部５ａの一側縁（外縁）側には所定高さでもって９０度曲げられた折曲部５ｂとから構成され、またこの折曲部５ｂの両端部には一対の係合片４がその折曲部５ｂと同じ方向で突設されるとともに、当接板５の平板部５ａの両端寄り位置には、当接板が井桁状に配置された状態で、両当接板５，５同士を連結するためのボルト６挿通用のボルト穴８が形成されている。
【００１９】
また、上記当接板５の折曲部５ｂの高さｈは、Ｈ型鋼２，３のフランジ部２ａ，３ａの厚さとほぼ同一に（好ましくは、同一かまたは僅かだけ低くされる）なるようにされている。
【００２０】
さらに、各当接板５における一対の係合片４，４同士の内側離間距離Ｌは、例えば下側Ｈ型鋼２のフランジ部２ａの両側に当接板（下方の当接板である）５が配置された状態で、これら両当接板５，５の外縁間の距離Ｓに等しくなるような長さにされている。したがって、当接板５が井桁状に組まれた状態では、上側または下側の当接板５の一方に形成された両係合片４，４により、他方の一対の当接板５，５同士が離間する水平方向での移動が阻止されることになる。
【００２１】
上記クランプ装置１を用いて、既設の下側Ｈ型鋼２上に、直交するように配置された上側Ｈ型鋼３を固定する場合について説明する。
まず、下側Ｈ型鋼２の上フランジ部２ａの両側縁に沿ってその下面（裏面）にそれぞれ平板部５ａが当接するように且つ上側Ｈ型鋼３を下方から横切るように一対の当接板５（５Ａ）を潜らせた状態（下方から跨ぐような状態）にしておき、次に上側Ｈ型鋼３の下フランジ部３ａの両側縁に沿ってその上面（裏面）にそれぞれ平板部５ａが当接するように且つ下側Ｈ型鋼２を上方から跨ぐように、一対の当接板５（５Ｂ）を配置する。
【００２２】
そして、このとき、上側および下側のいずれか一方の一対の当接板５，５に対し、他方の一対の当接板５，５を見た場合、一方の各当接板５，５における両係合片４，４間に、他方の両当接板５，５の各係合片４が位置するように配置される。勿論、この状態においては、井桁状の各交差部分では、ボルト穴８，８同士が一致しており、したがってこのボルト穴８，８同士にボルト６を挿通した後、ナット７により固定される。
【００２３】
この状態で、上下に配置された各当接板５，５同士は、互いに相手方の係合片４，４に引っ掛かることになり、したがって当接板５，５同士の水平方向での移動、すなわち水平方向でのずれが防止されるため、Ｈ型鋼２，３同士は確実にクランプされる。
【００２４】
このように、長方形状の平板部５ａの一端縁の両端部に係合片４がそれぞれ突設された４個の当接板５を井桁状に配置して直交するＨ型鋼２，３のフランジ部２ａ，３ａ同士を挟持するとともに、それぞれに設けられた係合片４同士により、井桁状に配置された当接板５が互いにずれるのを防止するようにしたので、非常に簡単且つ安価な構成にて、Ｈ型鋼同士を確実にクランプすることができる。
【００２５】
次に、本発明の第２の実施の形態に係るクランプ装置を、図７〜図１２に基づき説明する。
【００２６】
図７〜図１１に示すように、本第２の実施の形態に係るクランプ装置１１についても、上下に重ねて且つ互いに直交するように配置された一対のＨ型鋼１２，１３同士を固定するためのものである。
【００２７】
すなわち、このクランプ装置１１は、互いに接触しているＨ型鋼１２，１３同士の両フランジ部１２ａ，１３ａを案内し得る凹状部１４ａ，１５ａをそれぞれ有してその上下から挟持し得る一対の押え板１４，１５および両押え板１４，１５同士を連結するボルト・ナット（連結具）１６，１７からなる挟持体１８が４組（４個）と、各挟持体１８によりフランジ部１２ａ，１３ａ同士の交差部分を挟持した状態で、これら４組の挟持体１８を互いにその位置がずれないように連結する針金（索状体）１９とから構成されている。
【００２８】
上記各挟持体１８を構成する押え板１４，１５について説明すると、図１０〜図１２に示すように、平面視が三角形状に、すなわちフランジ部を挟持する先端側が細くされるとともにボルトが挿通される基端側が広くされ、且つ各フランジ部１２ａ，１３ａに接触する互いの対向面に形成される凹状部１４ａ，１５ａの形状は、その使用状態において、各フランジ部１２ａ，１３ａの形状に合致するようにされている。
【００２９】
すなわち、各挟持体１８は、両フランジ部１２ａ，１３ａの交差部分にＨ型鋼１２，１３の軸心に対し４５度の角度でもって外嵌（係合）されるため、下側Ｈ型鋼１２に接触する押え板１４に形成される凹状部１４ａの形状と、上側Ｈ型鋼１３に接触する押え板１５に形成される凹状部１５ａの形状とは、図１２の斜線にて示すように（下側を実線による斜線にて示し、上側を破線による斜線にて示す）、当該押え板１４，１５の中心線ａに対して互いに対称となる。
【００３０】
勿論、両押え板１４，１５の凹状部１４ａ，１５ａの中心線ａ上で且つ基端側（外側寄り）の適所にはボルト１６挿通用のボルト穴（穴部）１４ｂ，１５ｂが形成されるとともに、同じく両押え板１４，１５の基端寄り位置の互いの対向面には、それぞれ鋸刃状の凹凸部１４ｃ，１５ｃが形成されて、フランジ部１２ａ，１３ａを挟んでいる場合に両者がずれないように考慮されており、さらに各挟持体１８を各フランジ部１２ａ，１３ａに挟持させた際に、各挟持体１８が外れないにように針金（索状体）１９を挿通するための半円状（または１／４円状）の溝部１４ｄ，１５ｄが、各押え板１４，１５の対向面に形成されている。これら両押え板１４，１５を合わせることにより、針金１９を挿通し得る挿通穴２０が得られる。
【００３１】
上記クランプ装置１１により、既設の下側Ｈ型鋼１２上に、直交するように配置された上側Ｈ型鋼１３を固定する場合について説明する。
まず、図７に示すように、下側および上側Ｈ型鋼１２，１３のフランジ部１２ａ，１３ａ同士の交差部分にて、一対の押え板１４，１５を、その凹状部１４ａ，１５ａが各フランジ部１２ａ，１３ａに合致するように上下から押し当てた後、ボルト１６をそれぞれボルト穴１４ｂ，１５ｂに挿通させてナット１７を締め付ける。
【００３２】
この動作を、残りの両フランジ部１２ａ，１３ａの各交差部分にて行い、４組の挟持体１８にて下側Ｈ型鋼１２に上側Ｈ型鋼１３をクランプし、最後に、各挟持体１８に形成された挿通穴２０に針金１９を挿通させて、４組の挟持体１８を一体的に連結すればよい。
【００３３】
このように、互いに直交するＨ型鋼１２，１３の交差部分におけるフランジ部１２ａ，１３ａ同士を、４組の挟持体１８により挟持するとともにこれら４組の挟持体を針金１９により連結させたので、この場合も、非常に簡単且つ安価な構成にて、Ｈ型鋼同士を確実にクランプすることができる。
【００３４】
次に、本発明の第３の実施の形態に係るクランプ装置を、図１３〜図１６に基づき説明する。
図１３〜図１６に示すように、本第３の実施の形態に係るクランプ装置２１についても、上下に重ねて且つ互いに直交するように配置された一対のＨ型鋼２２，２３同士を固定するためのものである。
【００３５】
すなわち、このクランプ装置２１は、側面視がＣ字形状にされるとともにその両先端部に一方のＨ型鋼、例えば上側Ｈ型鋼２３の下側フランジ部２３ａの左右側縁部に係合し得る係合爪部２４ａがそれぞれ形成された一対の係合金具２４と、これら一対の係合金具２４，２４が他方のＨ型鋼、例えば下側Ｈ型鋼２２の上フランジ部２２ａの両側に配置されてそれぞれ両係合爪部２４ａ，２４ａにより上側Ｈ型鋼２３の下フランジ部２３ａに係合された状態で、各係合金具２４の中央に形成された凹状部２４ｂに挿通されてその一端側にて下側Ｈ型鋼２２の上フランジ部２２ａの下面（裏面）に当接されるとともに他端側に上側Ｈ型鋼２３の下フランジ部２３ａの下面（表面）を押圧し得る押しボルト（ボルト材）２５が螺挿された押え板（押え片）２６と、上記係合金具２４が下側Ｈ型鋼２２の両側に配置された状態で、当該両係合金具２４，２４同士が離間するのを阻止するための位置決め部材２７とから構成されている。
【００３６】
なお、この位置決め部材２７としては、両端部に係合金具２４の係合爪部２４ａに係合し得る折曲部２８ａが形成された所定長さの係合板２８と、この係合板２８の係合状態にて、その折曲部２８ａを係合金具２４の係合爪部２４ａに固定するための固定具、例えばビス２９とから構成されている。
【００３７】
上記クランプ装置２１により、既設の下側Ｈ型鋼２２上に、直交するように配置された上側Ｈ型鋼２３を固定する場合について説明する。
まず、下側Ｈ型鋼２２の上フランジ部２２ａの両側位置で、両係合爪部２４ａ，２４ａが上側Ｈ型鋼２３の下フランジ部２３ａの上面（裏面）に係合するように係合金具２４を配置するとともに、両係合金具２４の凹状部２４ｂに、一端側が下側Ｈ型鋼２２の上フランジ部２２ａの下面に当接するように押え板２６を挿入した後、その他端側に形成されたねじ穴２６ａに押しボルト２５を螺挿し、当該押え板２６の他端側を上側Ｈ型鋼２３の下フランジ部２３ａの下面から離間させて、梃子の原理で、係合金具２４を下方に付勢し、その両係合爪部２４ａ，２４ａにより上側Ｈ型鋼２３を下側Ｈ型鋼２２に押圧させて、上側Ｈ型鋼２３を下側Ｈ型鋼２２にクランプする。この作業を、下側Ｈ型鋼２２の両側にて行う。
【００３８】
そして、この後、上側Ｈ型鋼２３の下フランジ部２３ａの両側位置にて、左右に配置された両係合金具２４，２４の係合爪部２４ａ，２４ａに折曲部２８ａを係合させて、両係合金具２４，２４同士が離間しないように、すなわち位置がずれないようにしっかりと固定すればよい。
【００３９】
このように、互いに直交するＨ型鋼のフランジ部２２ａ，２３ａ同士をクランプするのに、下側Ｈ型鋼２２の上フランジ部２２ａの両側に係合金具２４を配置するとともに、その両端部に形成された係合爪部２４ａを上側Ｈ型鋼２３の下フランジ部２３ａの両側縁部に係合させた状態で、係合金具２４の凹状部２４ｂに押え板２６を挿入させた後、押しボルト２５により当該係合金具２４を下側Ｈ型鋼２２側に付勢させるようにしたので、この場合も、非常に簡単且つ安価な構成にて、Ｈ型鋼２２，２３同士を確実にクランプすることができる。
【００４０】
【発明の効果】
以上のように本発明の請求項１に係るクランプ装置の構成によると、両端部に係合片がそれぞれ突設された４個の当接板を井桁状に配置して交差するＨ型鋼のフランジ部同士を挟持するとともに、それぞれに設けられた係合片同士により、当接板が互いにずれないようにしたので、非常に簡単且つ安価な構成にて、Ｈ型鋼同士を確実にクランプすることができる。
【００４１】
また、請求項２に係るクランプ装置の構成によると、Ｈ型鋼の交差部分におけるフランジ部同士を４個の挟持体により挟持するとともにこれら４個の挟持体を索状体により互いに連結するようにしたので、やはり、非常に簡単且つ安価な構成にて、Ｈ型鋼同士を確実にクランプすることができる。
【００４２】
さらに、請求項３に係るクランプ装置の構成によると、上下の内一方の、例えば下側のＨ型鋼のフランジ部の両側に係合金具を配置するとともに、その両端部に形成された係合爪部を他方である上側のＨ型鋼のフランジ部の両側縁部に係合させた状態で、係合金具の凹状部に押え片を挿入させた後、ボルト材により当該係合金具を下側のＨ型鋼に付勢させるようにしたので、この場合も、非常に簡単且つ安価な構成にて、Ｈ型鋼同士を確実にクランプすることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a clamping device, and in particular, to one used when fixing a pair of H-shaped steels that intersect each other vertically.
[0002]
[Prior art]
When installing the equipment on the floor surface, it is necessary to support the support body of the equipment frame in advance on a steel mold, for example, an H-shaped steel, which is disposed as a framework on the floor surface.
[0003]
By the way, when the installation layout is changed when supporting the column body of the equipment frame to the H-shaped steel, that is, when it becomes impossible to support the H-shaped steel that has already been installed, it is newly added to the site. It is necessary to install another H-shaped steel, and it is necessary to fix it by a simple method for work.
[0004]
Conventionally, as an apparatus for fixing H-shaped steels, as shown in FIG. 17 , the flanges 51a and 52a of a pair of H-shaped steels 51 and 52 that cross each other vertically can be engaged and disengaged via bolts 53 and 54. There is a pair of clampers 55 and 56 that are provided on one support pin 57 that is swingable on the other (for example, see Patent Document 1).
[0005]
[Patent Document 1]
Japanese Patent Laid-Open No. 2000-170267
[Problems to be solved by the invention]
By the way, according to the conventional clamping device described above, the configuration in which the other clamper 56 is swingably provided by the support pin 57 in the recess 55a formed in the one clamper 55 is complicated and expensive to manufacture. Since the clampers 55 and 56 are swingably provided, there is a possibility that the two H-shaped steels 51 and 52 may be displaced from each other.
[0007]
Therefore, an object of the present invention is to provide a clamping device that can be reliably fixed at a low manufacturing cost when a pair of crossed H-shaped steels is fixed.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a clamping device according to claim 1 of the present invention is a clamping device for fixing a pair of H-shaped steels arranged so as to overlap each other and cross each other.
A rectangular flat plate portion having a contact surface that can come into contact with the back surface of the flange portion of the H-shaped steel whose surfaces are in contact with each other over a predetermined length, and substantially flush with the flange portion on one side edge side of the flat plate portion. Thus, a bent portion bent by 90 degrees, and a contact plate made of engagement pieces projecting from both ends of the bent portion and in the same direction as the bent portion,
Each of the contact plates is composed of a connecting tool that connects the ends of the contact plates in a state of being arranged in a cross shape so as to straddle the H-shaped steel different from the H-shaped steel to be contacted,
In addition, the distance between the engaging pieces projecting from both ends of each of the contact plates is such that the contact between the contact plates is in contact with the flange portion of one of the H-shaped steels in a state where the contact plates are connected like a cross beam. The two engagement pieces of the plate are made equal to the distance between the outer edges of the two contact plates so that the pair of contact plates that are in contact with the flange portion of the other H-shaped steel can be held. is there.
[0009]
According to the configuration of this clamping device, the four abutting plates with engaging pieces projecting from both ends are arranged in a cross-beam shape to sandwich the intersecting H-shaped steel flanges, and provided to each. Since the contact plates are not displaced from each other by the engagement pieces, the H-shaped steels can be reliably clamped with a very simple and inexpensive configuration.
[0010]
Further, the clamp device according to claim 2 is a clamp device for fixing a pair of H-shaped steels arranged so as to overlap each other at 90 degrees in the vertical direction,
Four sandwiching bodies that can be fitted at an angle of 45 degrees with respect to the axis of the two H-shaped steels at the intersections of the two flanges of the H-shaped steels that are in contact with each other, and the flanges that are in contact with each other The four sandwiching bodies that are externally fitted at the intersections between each other and sandwich the two flange portions are composed of cords that are connected so that their positions do not deviate from each other ,
Further, each of the sandwiching bodies is composed of a pair of pressing plates each formed with a concave portion capable of guiding both flange portions, and a connector for connecting the pair of pressing plates.
In addition, the shape of the concave portion formed on each of the pair of presser plates is symmetrical to each other so as to match each intersecting flange portion when fitted to each flange portion at an angle of 45 degrees. It is a thing.
[0011]
According to the configuration of this clamping device, the flange portions at the intersection of the H-shaped steels are sandwiched by the four sandwiching bodies and these four sandwiching bodies are connected to each other by the cord-like body. H-shaped steels can be reliably clamped with a simple and inexpensive configuration.
[0012]
