【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２２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）。
【０００５】

【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でもって当接し得るとともに両端部に相手方のＨ型鋼側に突出する係合片が設けられた４個の当接板と、
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、
且つ上記各当接板が井桁状に連結された状態においては、それぞれ端部にて突出された係合片により、相手方のＨ型鋼が、当該当接板が接触しているＨ型鋼に対する水平方向でのずれを規制す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型鋼同士のフランジ部を案内し得る凹状部が形成された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その凹状部が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】
さらに、請求項４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両フランジ部の表面に当接し得る所定長さの４個の当接板と、
上記各当接板が、当接される一方のＨ型鋼を跨ぐように且つ他方のＨ型鋼のフランジ部の端面に沿うように井桁状に配置された状態で、各端部の重なり部分の上下に配置されて当該当接板の表面およびフランジ部の裏面を押圧可能な押え片と、
上記井桁状に配置された当接板同士の重なり部分の上下に配置された押え片をこれら当接板と共に互いに連結する連結具とから構成したものである。
【００１５】
このクランプ装置の構成によると、４個の当接板を井桁状に配置して直交するＨ型鋼のフランジ部同士を両側から保持するとともに、押え片により、当該井桁状に組まれた当接板と共に両フランジ部同士を押圧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。
【００１６】
【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。
【００１７】
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。
【００１８】
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。
【００１９】
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。
【００２０】
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。
【００２１】
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。
【００２２】
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。
【００２３】
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。
【００２４】
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。
【００２５】
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。
【００２６】
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。
【００２７】
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。
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。
【００２８】
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。
【００２９】
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。
【００３０】
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。
【００３１】
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。
【００３２】
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。
【００３３】
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。
【００３４】
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。
【００３５】
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。
【００３６】
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。
【００３７】
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。
【００３８】
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。
【００３９】
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。
【００４０】
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。
【００４１】
次に、本発明の第４の実施の形態に係るクランプ装置を、図１７〜図２１に基づき説明する。
図１７に示すように、本第４の実施の形態に係るクランプ装置３１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３２，３３同士を固定するためのものである。
【００４２】
すなわち、このクランプ装置３１は、図１７〜図１９に示すように、互いに表面同士が接触しているＨ型鋼３２，３３のフランジ部３２ａ，３３ａの表面に当接し得る所定長さの４個の当接板３４と、これら各当接板３４が、当接される一方のＨ型鋼３２（または３３）を跨ぐように且つ他方のＨ型鋼３３（または３２）のフランジ部３３ａ（または３２ａ）の端縁（端面）に沿うように井桁状に配置された状態で、各端部の重なり部分の上下に配置されてこれら両当接板３４，３４の表面およびフランジ部３２ａ，３３ａの裏面を押圧可能な押え片３５と、井桁状に配置されて隣接する当接板３４，３４同士の重なり部分の上下に配置された押え片３５，３５をこれら当接板３４，３４と共に連結するボルト・ナット（連結具）３６，３７とから構成されている。勿論、各当接板３４の両端部には、ボルト３６を挿通するためのボルト穴３４ａが形成されている。
【００４３】
また、上記押え片３５は、図２０および図２１に示すように、当接板３４に当接する一端側の幅が広くされるとともにＨ型鋼３２，３３のフランジ部３２ａ，３３ａの裏面に当接する他端側の幅が徐々に狭くされている。さらに、この押え片３５の一端側にはボルト穴３５ａが形成されるとともに他端側にはフランジ部３２ａ，３３ａへの押圧を確実にするための半球状の突起３５ｂが形成され、またボルト穴３５ａを中心にしてその外縁側が僅かな角度θでもって当接板３４との接触面側に傾斜されている。なお、上記突起３５ｂおよび傾斜は、押え片３５によるフランジ部３２ａ，３３ａへの押え力を確実にするために設けられたものである。
【００４４】
なお、上記当接板３４の厚さは、Ｈ型鋼３２，３３のフランジ部３２ａ，３３ａの厚さにほぼ等しく（好ましくは、同一かまたは僅かだけ低くされる）、また当接板３４の長さは、各Ｈ型鋼３２，３３の幅に当接板３４の幅の２倍を加えた値にされている。
【００４５】
上記クランプ装置３１により、既設の下側Ｈ型鋼３２上に、直交するように配置された上側Ｈ型鋼３３を固定する場合について説明する。
まず、下側Ｈ型鋼３２の上フランジ部３２ａの上面（表面）に且つ上側Ｈ型鋼３３の下フランジ部３３ａの両側縁に沿って一対の当接板３４，３４を載置するとともに、上側Ｈ型鋼３３の下フランジ部３３ａの下面（表面）に且つ下側Ｈ型鋼３２の上フランジ部３２ａの両側縁に沿って一対の当接板３４，３４を下側から（下から跨ぐように、すなわち潜るように）接触させて４個の当接板３４を井桁状に配置した状態で、これら隣接する当接板３４，３４同士の各重なり部分の上下から押え片３５を当接させ（勿論、このとき、フランジ部３２ａ，３３ａの裏面についても押え片３５が当接されている）、そして上下一対の押え片３５，３５および上下の当接板３４，３４同士にボルト３６を挿通させた後、ナット３７により締め付ければよい。すなわち、井桁状に配置された当接板３４によりお互いがずれにくくされるとともに、上下からの押え片３５により両フランジ部３２ａ，３３ｂ同士がしっかりと押え付けられ（挟持され）ている。
【００４６】
このように、４個の当接板３４を井桁状に配置して直交するＨ型鋼３２，３３のフランジ部３２ａ，３３ａを一緒に両側から抱きかかえるように保持するとともに、押え片３５により、当該井桁状に組まれた当接板３４と共に両フランジ部３２ａ，３３ａ同士を上下から挟持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３２，３３同士を確実にクランプすることができる。
【００４７】
【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。
【００４８】
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。
【００４９】
また、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。
【００５０】
さらに、請求項４に係るクランプ装置の構成によると、４個の当接板を井桁状に配置して直交するＨ型鋼のフランジ部同士を両側から保持するとともに、押え片により、当該井桁状に組まれた当接板と共に両フランジ部同士を押圧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。

[0017]
Usually, when installing equipment, shelves, and the like, the support members are supported in advance by H-shaped steel as strength members (frame members) arranged in a predetermined direction on the floor surface. When the installation layout is changed in the lateral direction (the direction perpendicular to the axis of the H-section steel) with respect to the axis of the H-section steel, the H-section steel is newly placed on the existing H-section steel and the axis of the existing H-section steel. It is necessary to arrange them in a direction perpendicular to the center.
[0018]
The clamp device according to the present invention is used in such a case, that is, when mounting and fixing new H-shaped steels on an existing H-shaped steel so as to be orthogonal to each other (intersect at 90 degrees). is there.
[0019]
As shown in FIGS. 1 to 3, a clamp device 1 according to the first embodiment fixes a pair of H-shaped steels 2 and 3 that are vertically stacked and arranged so as to be orthogonal to each other. An engaging piece 4 which can abut with a predetermined length on the back surfaces of the flange portions 2a, 3a of the H-shaped steels 2, 3 whose surfaces are in contact with each other, and protrudes at both ends to the mating H-shaped steel 2, 3 side. Are provided, and each of these contact plates 5 is arranged in a crossbeam so as to straddle an H-shaped steel (3 or 2) different from the H-shaped steel (2 or 3) to be contacted. In a state in which the end plates are connected to each other with bolts and nuts (connecting tools) 6 and 7 connected to each other, and when the abutting plates 5 are connected in a cross-girder shape, the abutting plates are connected to each other. 5 are separated from the flange portions 2a and 3a by the engagement pieces 4 protruding from the ends. The can (misalignment) is prevented. Note that each contact plate 5 is formed with a bolt hole (hole portion) 8 through which the bolt 6 is inserted in a state of being arranged in a grid pattern.
[0020]
Here, the contact plate 5 will be described more specifically.
As shown in FIGS. 4 to 6, the contact plate 5 has a rectangular flat plate portion 5a having a contact surface capable of contacting the back surface of the H-shaped steel flange over a predetermined length, and the flat plate portion 5a. Is formed on one side edge (outer edge) side of the bent portion 5b at a predetermined height and bent by 90 degrees, and a pair of engaging pieces 4 is provided at both ends of the bent portion 5b. The two contact plates 5, 5 are connected to each other in a state where the contact plates are arranged in a cross-girder shape at positions near both ends of the flat plate portion 5a of the contact plate 5 while projecting in the same direction as the portion 5b. A bolt hole 8 for inserting a bolt 6 is formed.

The height h of the bent portion 5b of the contact plate 5 is set to be substantially the same as the thickness of the flange portions 2a and 3a of the H-shaped steels 2 and 3 (preferably the same or slightly lower). Have been.
[0022]
Further, the inner separation distance L between the pair of engagement pieces 4 and 4 in each contact plate 5 is, for example, a contact plate (a lower contact plate) 5 on both sides of the flange portion 2a of the lower H-section steel 2. Is arranged in such a manner that the distance S is equal to the distance S between the outer edges of the contact plates 5 and 5. Therefore, in a state where the contact plate 5 is assembled in a double-girder shape, the two engagement pieces 4, 4 formed on one of the upper and lower contact plates 5 allow the other pair of contact plates 5, 5 to be formed. Movement in the horizontal direction where the members are separated from each other is prevented.
