Description

【０００１】
【発明の属する技術分野】
この発明は、床下における配線・配管等の作業性を向上させるための、根太式床構造および連絡用床材に関するものである。
【０００２】
【従来の技術】
従来、床下に配線・配管材等の収容空間を形成するために、床材を所定高さに支持する床構造において、根太材を全て一定の向きに並設し、隣合う根太材間に床材を架設する、根太式の床構造があった。
【０００３】
【発明が解決しようとする課題】
かかる従来の床構造にあっては、根太材が全て一定の向きに設置されており、これら根太材に沿って配線・配管等を行うのは容易であるのに対して、これら根太材の長手方向に直交する方向に配線・配管等を行う必要が生じた場合、その作業にあたって、ケーブル等を、各根太材の下をくぐらせたり、または、根太材に設けられた透孔に挿通させる必要があり、それらの作業が非常に面倒であった。また、この場合、配線・配管等を行う作業者は、各根太材を跨ぎながら配線・配管等の作業を行わなければならず、作業性が悪かった。
【０００４】
この発明は、上記した従来の欠点を解決するためになされたものであり、その目的とするところは、床下における配線・配管等の作業性を向上させるための根太式床構造および連絡用床材を提供することにある。
【０００５】
【課題を解決するための手段】
この発明に係る根太式床構造および連絡用床材は、前記目的を達成するために、次の構成からなる。すなわち、
請求項１に記載の発明に係る根太式床構造は、根太材間に床材を架設して、その床材を所定高さに支持することにより、その床材下に配線・配管材等の収容空間を形成するものである。そして、この根太式床構造は、所定間隔をおいて互いに平行に設置される第１の根太材と、側面が前記第１の根太材の一方の端面と離れて向かい合って、長手方向が前記第１の根太材の長手方向とほぼ直角となるよう設置される第２の根太材と、前記第１の根太材の一方の端面側の端部と前記第２の根太材との間に架設される連絡用床材とを備える。これにより、この連絡用床材下に、第２の根太材の長手方向に沿って配線・配管材等を収容することができる。このとき、前記第１の根太材間に架設される第１の床材の他に、この連絡用床材を挟んで、第１の床材側とは反対側に、前記第２の根太材により所定高さに支持される第２の床材がある場合には、その第２の床材下または連絡用床材下に、第２の根太材の長手方向に沿って、配線・配管材等を収容することができる。また、第１の根太材の長手方向と同一の方向に配線・配管等を行う場合、第１の根太材の長手方向に沿って、配線・配管材等を収容することができる。こうすることで、ほぼ直交する２方向に配線・配管等を行う必要がある場合でも、従来の技術における床構造とは異なり、配線・配管材等を、互いに平行に設置された第１の根太材の下をくぐらせる必要がなく、また、配線・配管等を行う作業者は、第１の根太材を跨ぎながら配線・配管等の作業を行う必要がない。
【０００６】
【０００７】
また、請求項２に記載の発明に係る連絡用床材は、請求項１に記載の根太式床構造における連絡用床材であって、一方側に、前記第１の根太材の一方の端面側の端部間に跨って支持される第１被支持部を備え、他方側に、前記第２の根太材にその第２の根太材の長手方向に沿って支持される第２被支持部を備える。こうして、この連絡用床材は、第１の根太材の一方の端面側の端部と第２の根太材との間に架設される。そして、第１の根太材の長手方向とほぼ直交する方向に配線・配管等を行う場合、この連絡用床材下に、第２の根太材の長手方向に沿って、配線・配管材等を収容することができる。このとき、前記第１の根太材間に架設される第１の床材の他に、この連絡用床材を挟んで第１の床材側とは反対側に、前記第２の根太材により所定高さに支持される第２の床材がある場合には、その第２の床材下または連絡用床材下に、第２の根太材の長手方向に沿って、配線・配管材等を収容することができる。また、第１の根太材の長手方向と同一の方向に配線・配管等を行う場合、第１の根太材の長手方向に沿って、配線・配管材等を収容することができる。こうすることで、ほぼ直交する２方向に配線・配管等を行う必要がある場合でも、従来の技術における床構造とは異なり、配線・配管材等を、互いに平行に設置された第１の根太材の下をくぐらせる必要がなく、また、配線・配管等を行う作業者は、第１の根太材を跨ぎながら配線・配管等の作業を行う必要がない。
【０００８】
また、請求項３に記載の発明に係る連絡用床材のように、前記第２被支持部は、前記第２の根太材にその第２の根太材の長手方向に沿って形成された支持部と係合するよう、裏面側に開口する凹溝からなっていてもよい。こうして、凹溝からなる第２被支持部が、第２の根太材の支持部と係合して支持される。
【０００９】
【発明の実施の形態】
以下、この発明に係る根太式床構造および連絡用床材の実施の形態を図面に基づいて説明する。
【００１０】
図１ないし図４は、本発明に係る根太式床構造および連絡用床材の一実施の形態を示す。図中符号、１は、基礎床面、２は、所定間隔をおいて互いに平行に設置された第１の根太材である。３は、第２の根太材であり、側面３ａが第１の根太材２の一方の端面２ａと離れて向かい合って、長手方向が第１の根太材２の長手方向とほぼ直角となるよう設置される。４は、第１および第２の根太材２、３に取り付けられる受け部材、そして、５は、基礎床面１に立脚されて、受け部材４を介して、前記根太材２、３を所定高さに支持する支持脚である。６は、その支持脚５を、基礎床面１に取り付けるための取付部材である。７は、例えば、長方形形状等の矩形形状からなる連絡用床材であって、第１の根太材２、２の一方の端面２ａ、２ａ側の端部と、第２の根太材３との間に架設されて、それら第１の根太材２、２および第２の根太材３により所定高さに支持される。８は、第１の床材であり、例えば、長方形形状等の矩形形状からなり、第１の根太材２、２間に架設されて、それら第１の根太材２、２により所定高さに支持される。９は、第２の床材であり、第１の床材８と同一のものであって、連絡用床材７を挟んで第１の床材８側とは反対側に、第２の根太材３により、その一方の側端部９ａが所定高さに支持される。
【００１１】
ここで、第１の根太材２は、例えば、アルミニウム合金を押出成形して得られる型材からなり、図１に示すように、断面略逆Ｕ字状からなる本体部２ｂと、その本体部２ｂから上方に鉛直に延びるように型材の長手方向全てに渡って併設された突条部２ｃ、２ｃとから構成されている。そして、この第１の根太材２の突条部２ｃ、２ｃ上には、連絡用床材７が、後述する第１被支持部７ｇを介して載置され、また、第１の床材８が、その左右の側端部の裏面側にて下向きに開口形成された凹溝（図示せず）を介して載置される。第２の根太材３もまた、第１の根太材２と同一の材料、同一の断面形状からなる同一のものであって、本体部３ｂと、支持部としての突条部３ｃ、３ｃとから構成されている。そして、この第２の根太材３の突条部３ｃ、３ｃ上には、連絡用床材７が、後述する第２被支持部７ｈを介して載置され、また、第２の床材９が、その左右の側端部９ａの裏面側にて下向きに開口形成された凹溝９ｂのいずれか一方を介して載置される。
【００１２】
受け部材４は、第１の根太材２または第２の根太材３の下方から挿入されて、その本体部２ｂまたは３ｂの内側に嵌合するよう、その第１の根太材２または第２の根太材３の長手方向に長く延びる略直方体形状をしている。
【００１３】
支持脚５は、例えば、円柱状に形成され、その全周にネジ５ａが螺設されたボルト部材からなり、その上部が受け部材４のネジ孔（図示せず）と螺合することにより、受け部材４に取り付けられている。
【００１４】
取付部材６は、図１に示すように、基礎床面１に固着される固着部６ａと、支持脚５が挿入されて固定される保持筒６ｂとが、例えば、圧延鋼板等の板材を絞り加工することにより一体に形成されている。固着部６ａは、略四角形状で平板状に形成されており、例えば、接着剤により、その裏面が基礎床面１に固着される。一方、保持筒６ｂは、固着部６ａの中央から上方に突出するように円筒状に形成されている。そして、支持脚５が保持筒６ｂに上方より挿入される。また、保持筒６ｂの上端付近には、外周から内部に貫通するように孔（図示せず）が穿設されており、さらには、その孔と同心となるよう、保持筒６ｂの外周側に溶接ナット６ｃが、溶接されて取り付けられている。そして、止めネジ６ｄが、溶接ナット６ｃに螺合して、止めネジ６ｄの先端が、保持筒６ｂに挿入される支持脚５に当接することにより、支持脚５は、取付部材６に固定される。
【００１５】
連絡用床材７は、本体７ａと第１の緩衝部材７ｂと第２の緩衝部材７ｃとから構成されている。本体７ａは、例えば、アルミニウム合金を押出成形して得られる型材からなり、図２に示すように、断面略逆凸形状をしている。そして、この本体７ａは、型材の長手方向全てに渡って、その中央部分には断面矩形形状の二つの孔７ｄ、７ｄが形成され、また、その一方側の長手方向縁部には裏面側に開口する二つの第１の凹溝７ｅ、７ｅが形成され、そして、その他方側の長手方向縁部には裏面側に開口する一つの第２の凹溝７ｆが形成されている。
【００１６】
第１の緩衝部材７ｂおよび第２の緩衝部材７ｃは、合成ゴム等の弾性を備えたシート材からなり、本体７ａの一方側の長手方向縁部の裏面側および他方側の長手方向縁部の裏面側にそれぞれ、例えば、両面粘着テープ等により貼り付けられている。そして、第１の緩衝部材７ｂは、本体７ａの第１の凹溝７ｅ、７ｅを覆うように取り付けられており、その第１の凹溝７ｅ、７ｅを覆う部分は、平面状の載置面となって、第１の根太材２、２によって支持される第１被支持部７ｇを形成している。第２の緩衝部材７ｃは、本体７ａの第２の凹溝７ｆの形状に沿うようにその第２の凹溝７ｆに嵌まるように取り付けられており、その第２の凹溝７ｆに嵌まった部分は、裏面側に開口する凹溝となって、第２の根太材３によって支持される第２被支持部７ｈを形成している。こうして、連絡用床材７は、第１被支持部７ｇが、第１の根太材２、２の一方の端面２ａ、２ａ側の端部間に跨って支持され、第２被支持部７ｈが、第２の根太材３の突条部３ｃと係合して、その第２の根太材３の長手方向に沿って支持される。
【００１７】
次に、図３および図４を用いて、この根太式床構造を、床材下に収容される配線材と共に、組み付けの順に説明する。まず、図３に示すように、第１の根太材２、２を、左右方向が長手方向となるようにするとともに、所定間隔をおいて互いに平行に設置する。また、第２の根太材３を、第１の根太材２の左側に、側面３ａが第１の根太材２の一方の端面２ａと離れて向かい合って、長手方向が第１の根太材２の長手方向とほぼ直角となるよう、つまりは長手方向が前後方向となるよう設置する。また、第２の根太材３の左側には、長手方向がその第２の根太材３の長手方向と平行となるとともに所定間隔離すようにして、その第２の根太材３と同一のものからなる第３の根太材１０を設置する。そして、配線材１１を、その主幹路１１ａが第１の根太材２、２と第２の根太材３との間を第２の根太材３の長手方向に沿って、つまりは、第１の根太材２、２の長手方向と直角となる方向に延びるように配設する。次いで、配線材１１を、分岐路１１ｂ、１１ｂが主幹路１１ａの適宜位置においてその主幹路１１ａと直交するように右に分かれて、第１の根太材２、２間をそれら第１の根太材２、２の長手方向に沿って延びるように配設する。さらに、配線材１１を、第２の根太材３と第３の根太材１０との間をそれら根太材３、１０の長手方向に沿って延びるように配設する。
【００１８】
その後、図４に示すように、隣合う第１の根太材２、２の一方の端面２ａ、２ａ側の端部と第２の根太材３とに架け渡すように連絡用床材７、７を、例えば、縦長に載置し、また、隣合う第１の根太材２、２間に架け渡すように第１の床材８、８を、例えば、縦長に載置し、さらに、第２の根太材３と第３の根太材１０とに架け渡すように第２の床材９、９を、例えば、横長に載置する。こうして、連絡用床材７、７は、第１の根太材２、２および第２の根太材３により、所定高さに支持され、また、第１の床材８、８は、第１の根太材２、２により、所定高さに支持され、さらに、第２の床材９、９は、第２の根太材３および第３の根太材１０により、所定高さに支持される。そして、これら連絡用床材７、７、第１の床材８、８および第２の床材９、９下に配線材１１の収容空間が形成されて、連絡用床材７、７下には、配線材１１の主幹路１１ａが、第２の根太材３、３の長手方向に沿って収容され、また、第１の床材８、８下には、配線材１１の分岐路１１ｂが、第１の根太材２、２の長手方向に沿って収容され、さらに、第２の床材９、９下には、配線材１１が、第２および第３の根太材３、１０の長手方向に沿って収容される。
【００１９】
同様に、図５および図６を用いて、他の根太式床構造を、床材下に収容される配線材と共に、組み付けの順に説明する。まず、図５に示すように、第１の根太材２、２、第２の根太材３および第３の根太材１０を、前記根太式床構造（図３参照）と同様に設置する。そして、配線材１１を、その主幹路１１ａが第２の根太材３と第３の根太材１０との間をそれら根太材３、１０の長手方向に沿って、つまりは、第１の根太材２、２の長手方向と直角となる方向に延びるように配設する。次いで、配線材１１を、分岐路１１ｂ、１１ｂが主幹路１１ａの適宜位置においてその主幹路１１ａと直交するように右に分かれて、第２の根太材３の下をくぐり、第１の根太材２、２間をそれら第１の根太材２、２の長手方向に沿って延びるように配設する。
【００２０】
その後、図６に示すように、連絡用床材７、７、第１の床材８、８および第２の床材９、９を、前記根太式床構造（図４参照）と同様に載置する。こうして、これら連絡用床材７、７、第１の床材８、８および第２の床材９、９下に配線材１１の収容空間が形成されて、第２の床材９、９下には、配線材１１の主幹路１１ａが、第２および第３の根太材３、１０の長手方向に沿って収容され、また、連絡用床材７、７下には、配線材１１の分岐路１１ｂが、連絡用床材７、７を横切るように収容され、さらに、第１の床材８、８下には、配線材１１の分岐路１１ｂが、第１の根太材２、２の長手方向に沿って収容される。
【００２１】
次に、以上の構成からなる根太式床構造および連絡用床材の作用効果について説明する。第２の根太材３を、その長手方向が第１の根太材２、２の長手方向とほぼ直角となるよう設置することで、第１の根太材２、２の長手方向とほぼ直交する方向に配線を行う場合、連絡用床材７、７下（図４参照）または第２の床材９、９下に（図６参照）、第２の根太材３の長手方向に沿って、配線材１１を収容することができる。また、第１の根太材２、２の長手方向と同一の方向に配線を行う場合、第１の床材８、８下に（図４、６参照）、第１の根太材２、２の長手方向に沿って、配線材１１を収容することができる。こうすることで、ほぼ直交する２方向に配線を行う必要がある場合でも、従来の技術における床構造とは異なり、配線材１１を、互いに平行に設置された第１の根太材２、２の下をくぐらせる必要がなく、また、配線を行う作業者は、第１の根太材２、２を跨ぎながら配線の作業を行う必要がないので、床下における配線の作業性を向上させることができる。
【００２２】
なお、本発明は、上述した実施の形態に限定されるわけではなく、その他種々の変更が可能である。例えば、床材７、８、９下に配設するのは、配線材１１でなくとも、配管材その他の部材であってもよい。また、第２の根太材３は、側面３ａが第１の根太材２、２の一方の端面２ａ、２ａと離れて向かい合っているが、この第２の根太材３を、その側面３ａが第１の根太材２、２の一方の端面２ａ、２ａとほぼ当接して向かい合うように設置してもよい。この場合、連絡用床材７、７を省略して、第１の床材８、８と第２の床材９、９とを当接するようにして配設してもよい。また、連絡用床材７は、その第１被支持部７ｇが、隣合う第１の根太材２、２に支持されるものでなくとも、例えば、順に並ぶ三本、あるいはそれ以上の根太材２、２に支持されるように、型材の延びる方向に長く延びるものであってもよい。また、この発明に係る床構造は、平行に設置される第１の根太材２、２と、長手方向が第１の根太材２、２の長手方向とほぼ直角となるよう設置される第２の根太材３とを備えるものであり、配線材１１の所要の配設パターンに合わせて、第１の根太材２、２と第２の根太材３とを適宜組み合わせて設置することが可能である。
【００２３】
【発明の効果】
以上、詳述したところから明らかなように、この発明に係る根太式床構造および連絡用床材によれば、次の効果がある。
【００２４】
請求項１に記載された根太式床構造または請求項２若しくは３に記載された連絡用床材によれば、ほぼ直交する２方向の配線・配管等を、それぞれの根太材の長手方向に沿って行うことができるので、床下における配線・配管等の作業性を向上させることができる。
