Description

【０００１】
【発明の属する技術分野】
この発明は、床下に配線・配管材等の収容空間を形成するための床材を支持する支持脚の補強部材および、その補強部材を使用した床支持構造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支持構造において、特に耐振性を高めるために、例えば図１０に示すようなものがあった。ここで、符号２１は、床材、２２は、その床材２１が載せられる根太材、２３は、その根太材２２と嵌合する受け部材、２４は、その受け部材２３に上部がねじ込まれる支持脚である。こうして、支持脚２４は、それら根太材２２および受け部材２３を介して床材２１、２１を支持している。２５は、その支持脚２４を基礎床面２６に取り付ける取付部材としての台座である。そして、２７は、支持脚２４、２４間に架設されて、特にこの床支持構造の耐振性を高めるための補強部材である。この補強部材２７は、板材からなり、両端部に位置する取付部２７ａ、２７ａには、貫通孔（図示せず）が穿設されて、その貫通孔に支持脚２４が挿通される。そして、支持脚２４の全周に螺設されたネジ２４ａに螺合する上下三つのナット２８により、補強部材２７の上下の面が押さえられるようにして、その補強部材２７は、支持脚２４に取り付けられている。
【０００３】
【発明が解決しようとする課題】
このような従来の床材の支持構造においては、隣合う補強部材２７、２７が、直接連結されておらず、耐振性において大きな効果が得られなかった。また、補強部材２７を支持脚２４に組み付ける際に、補強部材２７の貫通孔を支持脚２４が挿通するように、補強部材２７を支持脚２４に嵌めなければならず、その取り付けが面倒であった。
【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、耐振強度が大きく、また、取り付けが容易な、床材を支持する支持脚の補強部材および、その補強部材を使用した床支持構造を提供することにある。
【０００５】
【課題を解決するための手段】
この発明に係る床材を支持する支持脚の補強部材および、その補強部材を使用した床支持構造は、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、床材を支持する支持脚の補強部材は、床下に配線・配管材等の収容空間を形成すべく、基礎床面に立脚されて前記床を形成する床材を所定高さに支持する、支持脚間に架設される補強部材であって、両端部に位置して前記支持脚に取り付けられる取付部と、それら取付部と一体に形成されてそれら取付部をつなぐ中間部とからなる。そして、前記取付部の少なくとも一方は、前記補強部材と同一形状の隣合う他の補強部材の取付部とともに、前記支持脚の周面に当接してその支持脚を挟むように、その支持脚への当接部を挟んだ両側に位置する連結ボルト等の固着具により、互いに連結されることで、その支持脚に取り付けられることを特徴とする。これにより、この補強部材の取付部は、隣合う他の補強部材の取付部とともに、互いに連結される。また、この補強部材の取付部は、隣合う他の補強部材の取付部とともに、支持脚の周面に当接してその支持脚を挟むように支持脚に取り付けられるので、従来の技術と違って、これら取付部に支持脚を挿通させる必要がなく、また、これら補強部材の取付部の連結により、これら補強部材が、同時に支持脚に取り付けられる。しかも、取付部における、支持脚への当接部の両側に位置する連結ボルト等の固着具により、これら取付部が、支持脚を強固に挟むことが可能となる。
【０００６】
また、請求項２に記載の発明に係る、床材を支持する支持脚の補強部材のように、前記両端部の取付部は、それぞれ、相対する方向から前記支持脚に当接するように取り付けられてもよい。つまり、補強部材の一方の取付部が、その補強部材が架設される両支持脚の一方の支持脚に、例えば、正面側から当接すると、他方の取付部は、両支持脚の他方の支持脚に、背面側から当接するというように、補強部材の両端部の取付部は、相対する方向から支持脚に当接する。
【０００７】
また、請求項３に記載の発明に係る、床材を支持する支持脚の補強部材のように、前記少なくとも一方の取付部には、前記当接部を挟むようにその両側に位置する、前記固着具の挿通部と固着部とが設けられてもよい。こうして、少なくとも一方の取付部は、その挿通部に挿通される固着具およびその固着部に固着される固着具により、他の補強部材の取付部と互いに連結される。
【０００８】
また、請求項４に記載の発明に係る、床材を支持する支持脚の補強部材のように、前記中間部は、上下方向の幅が、前記両端部の取付部をつなぐ方向に直交する水平方向の幅に比して大であるのが望ましい。これにより、補強部材の両端部の取付部をつなぐ方向に支持脚が傾斜するように、その支持脚に荷重が作用する場合、この補強部材は、中間部の上下方向の幅と前記両端部の取付部をつなぐ方向に直交する水平方向の幅とを逆にしたときに比べて、耐え得る前記荷重が大きくなり、また、剛性は高くなる。
【０００９】
また、請求項５に記載の発明に係る、補強部材を使用した床支持構造は、床下に配線・配管材等の収容空間を形成すべく基礎床面に立脚されて前記床を形成する床材を所定高さに支持する支持脚と、それら支持脚の、隣接する支持脚間のそれぞれに、架設される同一形状の前記補強部材とからなる。そして、隣合う補強部材の取付部が、前記支持脚の周面に当接してその支持脚を挟むように、前記当接部を挟んだ両側に位置する連結ボルト等の固着具により、互いに連結されるとともに、それら補強部材の取付部および中間部が、水平に配置されることを特徴とする。これにより、補強部材の両端部の取付部をつなぐ方向に支持脚が傾斜するように、その支持脚に荷重が作用する場合、この床支持構造は、隣接する支持脚間のそれぞれに架設される補強部材の取付部および中間部が水平に配置されないときに比べて、耐え得る前記荷重が大きくなり、また、剛性は高くなる。
【００１０】
【発明の実施の形態】
以下、この発明に係る床材を支持する支持脚の補強部材および、その補強部材を使用した床支持構造の実施の形態を図面に基づいて説明する。
【００１１】
図１ないし図６は、本発明に係る床材を支持する支持脚の補強部材および、その補強部材を使用した床支持構造を、根太式タイプの床構造に適用した一実施の形態を示す。図中符号、１は、基礎床面、２は、床を形成する床材である。３は、床下に配線・配管材等の収容空間Ｓを形成するために、基礎床面１に立脚されて、根太材４および受け部材５を介して、前記床材２を所定高さに支持する支持脚である。６は、その支持脚３を、基礎床面１に取り付けるための取付部材である。７は、隣合う根太材４、４を支持する前記支持脚３、３間に架設され、あるいは（および）、それらの根太材４、４の長手方向に沿って配置される前記支持脚３、３間に架設される補強部材である。
【００１２】
ここで、根太材４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、断面略逆Ｕ字状からなる本体部４ａと、その本体部４ａ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、それぞれに床材２、２が載置される第１の突条部４ｂ、４ｂと、本体部４ａの両側面から、それぞれ側方に突出して、断面略Ｌ字形状からなる第２の突条部４ｃ、４ｃとから構成されている。
【００１３】
受け部材５は、根太材４の下方から挿入されて、その本体部４ａの内側に嵌合するよう、その根太材４の長手方向に沿って長く延びる略直方体形状をしている。
【００１４】
支持脚３は、例えば、円柱状に形成され、その全周にネジ３ａが螺設されたボルト部材からなり、その上部が受け部材５のネジ孔（図示せず）と螺合することにより、受け部材５に取り付けられている。
【００１５】
取付部材６は、基礎床面１に固着される固着部６ａと、支持脚３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３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、先端が、保持筒６ｂに挿入される支持脚３に当接することにより、支持脚３は、取付部材６に固定される。こうして、支持脚３、３は、取付部材６、６を介して基礎床面１に立脚されて、床を形成する床材２、２を、受け部材５、５および根太材４、４を介して所定高さに支持することとなる。
【００１６】
補強部材７は、両端部に位置して前記支持脚３、３に取り付けられる取付部７ａ、７ａと、それら取付部７ａ、７ａをつなぐ中間部７ｂとが、例えば、圧延鋼板等の板材により一体に形成されている。取付部７ａは、図４および図５に明示するように、矩形の平板のほぼ中央を半円筒状に湾曲させた形状をしており、その湾曲する湾曲部７ｃを挟むように、先端部分の平板部７ｄに、後述する連結ボルト９ａ等の固着具が挿通される挿通部としての貫通孔７ｅが、そして、基端部分の平板部７ｆに同じく貫通孔７ｇが、並んで穿設されている。さらに、基端部分の平板部７ｇには、湾曲部７ｃの張出し側と同一の側に、貫通孔７ｇと同心となるよう、溶接ナット７ｈが溶接されており、これら貫通孔７ｇと溶接ナット７ｈとで、後述する連結ボルト９ｂ等の固着具が固着される固着部が形成される。ここで、両端部の取付部７ａ、７ａの一方は、湾曲部７ｃが正面側に張り出すように湾曲し、取付部７ａ、７ａの他方は、湾曲部７ｃが背面側に張り出すように湾曲するというように、これら湾曲部７ｃ、７ｃは、相対する方向に張り出すように湾曲している。一方、中間部７ｂは、断面略Ｃ字状に形成されて（図６参照）、両端部の取付部７ａ、７ａをつなぐように延びており、それら両端部の取付部７ａ、７ａとともに、水平に延びるように形成されている。さらに、この中間部７ｂは、上下方向の幅Ｗ１が、両端部の取付部７ａ、７ａをつなぐ方向に直交する水平方向の幅、つまりは板厚方向の幅Ｗ２に比して大となっている（図４、図５参照）。
【００１７】
そして、補強部材７の一方の取付部７ａは、隣合う他の補強部材８の取付部８ａとともに、それら取付部７ａ、８ａの湾曲部７ｃ、８ｃの内側が、両側から一方の支持脚３の周面に当接して、その支持脚３を挟むように配置される。ここで、この補強部材７と隣合う他の補強部材８は、補強部材７と同一形状であり、補強部材７が鉛直軸回りに１８０度回転した向きと同一の向きとなるように配置される。そして、補強部材７の貫通孔７ｅを挿通し他の補強部材８の溶接ナット８ｈにねじ込まれる固着具としての連結ボルト９ａ、および、他の補強部材８の貫通孔（図示せず）を挿通しこの補強部材７の溶接ナット７ｈにねじ込まれる固着具としての連結ボルト９ｂにより、これら取付部７ａ、８ａは、互いに連結され、さらに、この連結により、これら取付部７ａ、８ａは、一方の支持脚３に取り付けられる。この補強部材７の他方の取付部７ａもまた、同様にして、他方の支持脚３に取り付けられる。このとき、両端部の取付部７ａ、７ａは、それらの湾曲部７ｃ、７ｃが相対する方向に張り出すように湾曲しているので、これら両端部の取付部７ａ、７ａは、一方の取付部７ａが、一方の支持脚３に、例えば、正面側から当接すると、他方の取付部７ａは、他方の支持脚３に、背面側から当接するというように、それぞれ、相対する方向から支持脚３、３に当接するように、これら支持脚３、３に取り付けられる。こうして、支持脚３、３に取り付けられた、この補強部材７およびそれと隣合う他の補強部材８、８の、取付部７ａ、７ａ、８ａ、８ａおよび中間部７ｂ、８ｂ、８ｂは、水平に配置されることとなる（図２参照）。
【００１８】
次に、以上の構成からなる床材を支持する支持脚の補強部材および、その補強部材を使用した床支持構造の作用効果について説明する。この補強部材７の取付部７ａは、隣合う他の補強部材８の取付部８ａとともに、互いに、直接連結されており、したがって、それらの取付部７ａ、８ａが直接連結されず別々に支持脚３に取り付けられる場合に比べて、この補強部材７を使用した床支持構造の耐振強度が大きくなる。また、この補強部材７の取付部７ａは、その湾曲部７ｃが、隣合う他の補強部材８の取付部８ａの湾曲部８ｃとともに、両側から支持脚３の周面に当接してその支持脚３を挟むように、支持脚３に取り付けられるので、従来の技術と違って、これら取付部７ａ、８ａに支持脚３を挿通させる必要がなく、また、これら補強部材７、８の取付部７ａ、８ａの連結により、これら補強部材７、８が、同時に支持脚３に取り付けられる。したがって、支持脚３への、これらの補強部材７、８の取り付けが容易であるとともに施工性に優れる。
【００１９】
また、補強部材７の取付部７ａは、その貫通孔７ｅに挿通される連結ボルト９ａおよびその溶接ナット７ｈにねじ込まれる連結ボルト９ｂにより、他の補強部材８の取付部８ａと互いに連結される。そして、これら貫通孔７ｅおよび溶接ナット７ｈは、支持脚３への当接部である湾曲部７ｃを挟むようにその両側に位置しているので、前記連結ボルト９ａ、９ｂもまた、支持脚３への当接部（湾曲部７ｃ）の両側に位置することとなり、それらの連結ボルト９ａ、９ｂにより、これら取付部７ａ、８ａが、支持脚３を強固に挟むことが可能となる。したがって、これらの補強部材７、８を、支持脚３に強固に取り付けることができる。
【００２０】
また、補強部材７の両端部の取付部７ａ、７ａをつなぐ方向、つまりは図２中の左右方向に支持脚３、３が傾斜するように、それらの支持脚３、３に荷重が作用する場合、この補強部材７は、中間部７ｂの上下方向の幅Ｗ１が板厚方向の幅Ｗ２に比して大であり、この逆のときに比べて、耐え得る前記荷重が大きくなり、また、剛性は高くなる。したがって、この補強部材７を使用した床支持構造は、一層、耐振強度が大きくなる。
【００２１】
また、同様に、図２中の左右方向に支持脚３、３が傾斜するように、その支持脚３、３に荷重が作用する場合、この床支持構造は、隣接する支持脚３、３間のそれぞれに架設される補強部材７、８、８の取付部７ａ、７ａ、８ａ、８ａおよび中間部７ｂ、８ｂ、８ｂが、水平に配置されており、そうでないときに比べて、耐え得る前記荷重が大きくなり、また、剛性は高くなる。したがって、これらの補強部材７、８、８を使用した床支持構造は、さらに一層、耐振強度が大きくなる。
【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、図７に示すように、補強部材７、８の中間部７ｂ、８ｂを、両端部の取付部７ａ、７ａ、８ａ、８ａに比して上下の一方に寄せるように形成し、かつ、支持脚３、３間のそれぞれで、それら中間部７ｂ、８ｂが上下方向において互い違いとなるように、前記補強部材７、８を支持脚３、３に取り付けてもよい。もっとも、この場合には、これらの補強部材７、８の中間部７ｂ、８ｂ、８ｂは、水平に配置されないこととなる。
【００２３】
また、図８に示すように、例えば、補強部材７の左隣に、他の補強部材８が連結されない場合は、他の補強部材８の取付部８ａと同等の構造からなる取付部１０ａのみからなる端末部材１０を使用することができる。
【００２４】
また、図９に示すように、補強部材７の取付部７ａの湾曲部７ｃを、半円筒状ではなく、略１／４円筒状とし、さらに、先端部分の平板部７ｄを、基端部分の平板部７ｆに対して直角に屈曲するように形成してもよい。この場合、補強部材７は、その補強部材７に直交するように配置される他の補強部材８、８に対して直交的に隣合い、また、その補強部材７と同一方向に延びるように配置される他の補強部材８に対しては、支持脚３を挟んで対峙的に隣合って、それらの取付部７ａ、８ａ、８ａ、８ａの湾曲部７ｃ、８ｃ、８ｃ、８ｃの内側が、支持脚３の周面に当接して、その支持脚３を挟むように配置される。そして、溶接ナット７ｈ、８ｈ、８ｈ、８ｈにねじ込まれる固着具としての連結ボルト９、９、９、９により、これら取付部７ａ、８ａ、８ａ、８ａは、互いに直接的もしくは間接的に連結され、さらに、この連結により、これら取付部７ａ、８ａ、８ａ、８ａは、支持脚３に取り付けられる。ここで、この補強部材７と隣合う他の補強部材８、８、８は、補強部材７と同一形状であり、補強部材７が鉛直軸回りに９０度、１８０度、そして２７０度回転した向きと同一の向きとなるように配置される。こうして、補強部材７、８、８、８は、取付部７ａ、８ａ、８ａ、８ａを介して、前後左右につながることとなる。
【００２５】
また、この実施の形態においては、この発明を根太式タイプの床構造に適用した例を示したが、それ以外にフリーアクセスタイプの床構造に適用してもよい。ここで、フリーアクセスタイプとは、根太式タイプのような床材２、２が根太材４、４に沿って並べられるものではなく、床材のコーナー部がポイント的に支持脚によって支持されるものである。また、補強部材７の取付部７ａ、７ａの基端部分の平板部７ｆ、７ｆには、溶接ナット７ｈ、７ｈを溶接したが、代わりに、平板部７ｆ、７ｆの板材に直接、ネジ孔を穿設してもよい。また、補強部材７の両端部の取付部７ａ、７ａに形成された湾曲部７ｃ、７ｃは、それぞれ相対する方向に張り出すように湾曲しなくとも、例えば、図７に示される実施の形態のように、同一方向に張り出すように湾曲するものであってもよい。この場合、これら両端部の取付部７ａ、７ａは、それぞれ、同一の方向からそれぞれの支持脚３、３に当接するように、それら支持脚３、３に取り付けられる。
【００２６】
【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、床材を支持する支持脚の補強部材および、その補強部材を使用した床支持構造によれば、次の効果がある。
【００２７】
請求項１ないし３に記載された、床材を支持する支持脚の補強部材によれば、この補強部材の取付部は、隣合う他の補強部材の取付部とともに、互いに連結されるので、この補強部材を使用した床支持構造は、耐振強度が大きくなる。そして、この補強部材は、隣合う他の補強部材とともに、支持脚を挟むように支持脚に取り付けられるので、従来の技術と違って、これら補強部材に支持脚を挿通させる必要がなく、また、これら補強部材の連結により、これら補強部材が、同時に支持脚に取り付けられるので、その取り付けが容易であるとともに施工性に優れる。
【００２８】
また、取付部における、支持脚への当接部の両側に位置する連結ボルト等の固着具により、取付部が支持脚を強固に挟むので、この補強部材は、支持脚に強固に取り付けられる。
【００２９】
また、請求項４に記載された、床材を支持する支持脚の補強部材によれば、この補強部材を使用した床支持構造は、一層、耐振強度が大きくなる。
【００３０】
更に、請求項５に記載された、補強部材を使用した床支持構造によれば、耐振性に優れる。

BACKGROUND OF THE INVENTION
The present invention relates to a reinforcing member for a supporting leg that supports a floor material for forming an accommodation space for wiring and piping materials under the floor, and a floor support structure using the reinforcing member.
[0002]
[Prior art]
Conventionally, a floor support structure for supporting a floor material at a predetermined height in order to form a housing space for wiring, piping, etc. under the floor has a structure as shown in FIG. It was. Here, reference numeral 21 is a floor material, 22 is a joist member on which the floor material 21 is placed, 23 is a receiving member fitted to the joist member 22, and 24 is a support whose upper part is screwed into the receiving member 23. It is a leg. In this way, the support legs 24 support the floor materials 21 and 21 via the joists 22 and the receiving members 23. Reference numeral 25 denotes a pedestal as an attachment member for attaching the support leg 24 to the foundation floor surface 26. Reference numeral 27 denotes a reinforcing member that is installed between the support legs 24 and 24, and particularly for enhancing the vibration resistance of the floor support structure. The reinforcing member 27 is made of a plate material, and through holes (not shown) are formed in the mounting portions 27a and 27a located at both ends, and the support legs 24 are inserted into the through holes. Then, the upper and lower surfaces of the reinforcing member 27 are pressed by the upper and lower three nuts 28 screwed to the screws 24 a screwed on the entire circumference of the supporting leg 24, so that the reinforcing member 27 is attached to the supporting leg 24. It is attached.
[0003]
[Problems to be solved by the invention]
In such a conventional floor material support structure, the adjacent reinforcing members 27 are not directly connected, and a great effect in vibration resistance cannot be obtained. Further, when the reinforcement member 27 is assembled to the support leg 24, the reinforcement member 27 must be fitted into the support leg 24 so that the support leg 24 is inserted through the through hole of the reinforcement member 27, and the mounting thereof is troublesome. It was.
[0004]
The present invention has been made in order to solve the above-described conventional drawbacks. The object of the present invention is to provide a reinforcing member for a supporting leg that supports a flooring and has a high vibration resistance and can be easily attached. Another object of the present invention is to provide a floor support structure using the reinforcing member.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a reinforcing member for supporting legs for supporting a flooring according to the present invention and a floor supporting structure using the reinforcing member have the following configuration. That is,
The reinforcing member of the support leg that supports the flooring according to the invention of claim 1 is a floor that is erected on the foundation floor to form the floor so as to form an accommodation space for wiring, piping, etc. under the floor. Reinforcing members installed between support legs that support the material at a predetermined height, and mounting portions that are located at both ends and are attached to the support legs, and are formed integrally with the mounting portions. It consists of the middle part which connects. Then, at least one of the attachment portions, together with the attachment portions of other adjacent reinforcing members having the same shape as the reinforcement member, is attached to the support legs so as to abut on the peripheral surface of the support legs and sandwich the support legs. It is characterized by being attached to the supporting leg by being connected to each other by a fixing tool such as a connecting bolt located on both sides of the contact part . Thereby, the attachment part of this reinforcement member is mutually connected with the attachment part of another adjacent reinforcement member. Also, this reinforcing member mounting part, together with the other adjacent reinforcing member mounting part, is attached to the support leg so as to abut on the peripheral surface of the support leg and sandwich the support leg, so unlike the conventional technology The support legs do not need to be inserted through the attachment portions, and the reinforcement members are simultaneously attached to the support legs by connecting the attachment portions of the reinforcement members. In addition, the attachment portions can firmly hold the support legs by fixing tools such as connecting bolts located on both sides of the contact portions on the support legs in the attachment portions.
[0006]
Moreover, like the reinforcing member of the support leg which supports the flooring according to the invention described in claim 2, the attachment portions of the both end portions are each attached so as to contact the support leg from the opposite direction. May be. In other words, when one attachment portion of the reinforcing member comes into contact with one support leg of both support legs on which the reinforcement member is installed, for example, from the front side, the other attachment portion is supported by the other of the support legs. The attachment portions at both ends of the reinforcing member abut on the support leg from the opposite direction so as to abut on the leg from the back side.
[0007]
Further, according to the invention of claim 3, as reinforcing members of the support legs for supporting the flooring, wherein at least one of the mounting portion, positioned on both sides so as to sandwich the front Kito contact portion, wherein the insertion portion and the solid adhesion of the fastener may be provided. Thus, at least one of the mounting portion, the insertion is that solid Chakugu and solid Chakugu that is fixed to the fixing portion on the insertion portion are connected to each other and the mounting portion of the other reinforcing member.
[0008]
Moreover, like the reinforcement member of the support leg which supports the flooring according to the invention described in claim 4, the intermediate portion has a horizontal width that is perpendicular to the direction connecting the attachment portions of the both end portions. It is desirable that it is larger than the width in the direction. Thus, when a load is applied to the support leg so that the support leg is inclined in a direction connecting the attachment portions at both ends of the reinforcement member, the reinforcement member has the vertical width of the intermediate portion and the width of the both ends. Compared with the case where the width in the horizontal direction perpendicular to the direction connecting the attachment portions is reversed, the load that can be withstood is increased and the rigidity is increased.
[0009]
In addition, the floor support structure using the reinforcing member according to the invention of claim 5 is a flooring which is erected on a foundation floor to form a storage space for wiring and piping under the floor to form the floor. The supporting leg is supported at a predetermined height, and the reinforcing member having the same shape is installed between the supporting legs adjacent to each other. Then, the attachment portions of the adjacent reinforcing members are connected to each other by fixing tools such as connection bolts located on both sides of the contact portion so that the support legs are in contact with and sandwich the support legs. In addition, the attachment portion and the intermediate portion of the reinforcing members are arranged horizontally. Thus, when a load acts on the support legs so that the support legs are inclined in the direction connecting the attachment portions at both ends of the reinforcing member, the floor support structure is installed between the adjacent support legs. Compared with the case where the attachment portion and the intermediate portion of the reinforcing member are not horizontally disposed, the load that can be withstood is increased and the rigidity is increased.

As shown in FIGS. 4 and 5, the mounting portion 7 a has a shape in which the substantially center of a rectangular flat plate is curved in a semi-cylindrical shape, and the tip portion is sandwiched between the curved bending portions 7 c. A through hole 7e as an insertion portion through which a fixing tool such as a connecting bolt 9a, which will be described later, is inserted is formed in the flat plate portion 7d, and a through hole 7g is similarly formed in the flat plate portion 7f of the base end portion. . Further, a welding nut 7h is welded to the flat plate portion 7g at the base end portion so as to be concentric with the through hole 7g on the same side as the projecting side of the curved portion 7c, and the through hole 7g and the welding nut 7h. Thus, a fixing portion to which a fixing tool such as a connecting bolt 9b described later is fixed is formed. Here, one of the attachment portions 7a, 7a at both ends is curved so that the curved portion 7c projects to the front side, and the other of the attachment portions 7a, 7a is curved so that the curved portion 7c projects to the rear side. As described above, the curved portions 7c and 7c are curved so as to project in opposite directions. On the other hand, the intermediate portion 7b is formed in a substantially C-shaped cross section (see FIG. 6) and extends so as to connect the attachment portions 7a and 7a at both ends, and together with the attachment portions 7a and 7a at both ends, It is formed to extend. Further, the intermediate portion 7b has a vertical width W1 larger than a horizontal width perpendicular to the direction connecting the attachment portions 7a and 7a at both ends, that is, a width W2 in the thickness direction. (See FIGS. 4 and 5).
[0017]
And one attachment part 7a of the reinforcement member 7 is the inside of the curved parts 7c and 8c of these attachment parts 7a and 8a with the attachment part 8a of the other adjacent reinforcement member 8, and one support leg 3 from both sides.

Here, the other reinforcing member 8 adjacent to the reinforcing member 7 has the same shape as the reinforcing member 7 and is disposed in the same direction as the direction in which the reinforcing member 7 is rotated 180 degrees around the vertical axis. . Then, through the through hole 7e of the reinforcing member 7, the connecting bolt 9a as a fastener to be screwed into the welding nut 8h of the other reinforcing member 8 and the through hole (not shown) of the other reinforcing member 8 are inserted. The attachment portions 7a and 8a are connected to each other by a connection bolt 9b as a fastener to be screwed into the welding nut 7h of the reinforcing member 7. Further, by this connection, the attachment portions 7a and 8a are connected to one support leg. 3 is attached. The other attachment portion 7a of the reinforcing member 7 is also attached to the other support leg 3 in the same manner. At this time, the mounting portions 7a, 7a at both ends are curved so that the curved portions 7c, 7c protrude in the opposite direction, so that the mounting portions 7a, 7a at both ends are attached to one mounting portion. When 7a comes into contact with one support leg 3, for example, from the front side, the other mounting portion 7a comes into contact with the other support leg 3 from the back side. They are attached to these support legs 3 and 3 so as to abut against 3 and 3. Thus, the mounting portions 7a, 7a, 8a and 8a and the intermediate portions 7b, 8b and 8b of the reinforcing member 7 and the other reinforcing members 8 and 8 adjacent thereto attached to the support legs 3 and 3 are horizontally arranged.

Further, a load acts on the support legs 3 and 3 so that the support legs 3 and 3 are inclined in the direction connecting the attachment portions 7a and 7a at both ends of the reinforcing member 7, that is, in the left-right direction in FIG. In this case, the reinforcing member 7 has a larger width W1 in the vertical direction of the intermediate portion 7b than the width W2 in the plate thickness direction, and the load that can be endured is larger than the opposite case, Stiffness is increased. Therefore, the floor support structure using this reinforcing member 7 further increases the vibration resistance strength.
[0021]
Similarly, when a load is applied to the support legs 3, 3 so that the support legs 3, 3 are inclined in the left-right direction in FIG. 2, this floor support structure is formed between the adjacent support legs 3, 3. The mounting portions 7a, 7a, 8a, 8a and the intermediate portions 7b, 8b, 8b of the reinforcing members 7, 8, 8 installed on each of the above are disposed horizontally, and can withstand as compared with the case where they are not. The load increases and the rigidity increases. Therefore, the floor support structure using these reinforcing members 7, 8, 8 further increases the vibration resistance strength.
[0022]
In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, as shown in FIG. 7, the intermediate portions 7 b and 8 b of the reinforcing members 7 and 8 are formed so as to be closer to one of the upper and lower sides than the attachment portions 7 a, 7 a, 8 a and 8 a at both ends, and The reinforcing members 7 and 8 may be attached to the support legs 3 and 3 so that the intermediate portions 7b and 8b are staggered in the vertical direction between the support legs 3 and 3, respectively. In this case, however, the intermediate portions 7b, 8b, 8b of the reinforcing members 7, 8 are not horizontally arranged.
[0023]
As shown in FIG. 8, for example, when the other reinforcing member 8 is not connected to the left side of the reinforcing member 7, only from the mounting portion 10 a having the same structure as the mounting portion 8 a of the other reinforcing member 8. A terminal member 10 can be used.
[0024]
Further, as shown in FIG. 9, the curved portion 7c of the mounting portion 7a of the reinforcing member 7 is not a semi-cylindrical shape, but a substantially 1/4 cylindrical shape, and the flat plate portion 7d at the distal end portion is formed at the proximal end portion. You may form so that it may be bent at right angle with respect to the flat plate part 7f. In this case, the reinforcing member 7 is arranged so as to be orthogonal to the other reinforcing members 8, 8 arranged so as to be orthogonal to the reinforcing member 7 and to extend in the same direction as the reinforcing member 7. The other reinforcing members 8 are adjacent to each other across the support leg 3 and the insides of the curved portions 7c, 8c, 8c, 8c of the mounting portions 7a, 8a, 8a, 8a are It arrange | positions so that it may contact | abut to the surrounding surface of the support leg 3, and the support leg 3 may be pinched | interposed. And these attachment parts 7a, 8a, 8a, 8a are directly or indirectly connected to each other by connecting bolts 9, 9, 9, 9 as fasteners screwed into the welding nuts 7h, 8h, 8h, 8h. In addition, the attachment portions 7a, 8a, 8a, 8a are attached to the support leg 3 by this connection. Here, the other reinforcing members 8, 8, and 8 adjacent to the reinforcing member 7 have the same shape as the reinforcing member 7, and the direction in which the reinforcing member 7 is rotated 90 degrees, 180 degrees, and 270 degrees around the vertical axis. Are arranged in the same direction. Thus, the reinforcing members 7, 8, 8, 8 are connected to the front, rear, left, and right through the attachment portions 7a, 8a, 8a, 8a.
[0025]
In this embodiment, the present invention is applied to a joist type floor structure. However, the present invention may be applied to a free access type floor structure. Here, the free access type is not a floor material 2 or 2 like the joist type, but is arranged along the joist materials 4 and 4, and the corner portion of the floor material is supported by the support legs in a point manner. Is. Further, welding nuts 7h and 7h are welded to the flat plate portions 7f and 7f of the base end portions of the attachment portions 7a and 7a of the reinforcing member 7, but instead, screw holes are directly formed in the plate materials of the flat plate portions 7f and 7f. You may drill. Further, the curved portions 7c, 7c formed on the attachment portions 7a, 7a at both ends of the reinforcing member 7 do not bend so as to project in opposite directions, for example, in the embodiment shown in FIG. Thus, it may be curved so as to project in the same direction. In this case, the attachment portions 7a and 7a at both ends are attached to the support legs 3 and 3 so as to come into contact with the support legs 3 and 3 from the same direction.
