【発明の属する技術分野】
本発明は、オフィスビル内の事務所あるいはインテリジェントビル内の配線システムとして広く採用されている２重床用のフロアーパネルの支持具に関し、詳しくはフロアーパネルの角部を載設して固定するためのフロアーパネルの支持具に関するものである。
【０００２】
【従来の技術】
オフィスビル内の事務所あるいはインテリジェントビル内の配線システムとして広く採用されている２重床用のフロアーパネルの支持具７’としては従来から図９に示されるようなものが知られている。この従来の支持具７’はスラブのような床下地１’に載設するための取付けベース２’から高さ調整用の軸部３’を立設し、この軸部３’の上端部にアルミダイキャスト製のパネル受け部５’を螺合して取付け、アルミダイキャスト製のパネル受け部５’の中央部に設けた雌ねじ部８’にロック部６’の雄ねじ部９’を螺合して構成していた。そして、図１０に示すように、スラブのような床下地１’に支持具７’の取付けベース２’を載設し、ロック部６’を外した状態でパネル受け部５’にフロアーパネル４’の角部を載置し、その後、ロック部６’の雄ねじ部９’をパネル受け部５’の中央部の雌ねじ部８’に螺合してロック部６’によりパネル受け部５’に載置したフロアーパネル４’の角部を上から押さえ付けることでフロアーパネル４’の角部を固定していた。図中５０はフロアーパネル４’の上面に敷設されるタイルカーペットである。
【０００３】
このような構成の従来の支持具７’にあってはパネル受け部５’には雌ねじ部８’を形成して該雌ねじ部８’にロック部６’の雄ねじ部９’を螺合して上記フロアーパネル４’の角部の固定をするため、必然的にパネル受け部５’は強度の強いアルミダイキャスト製のコストの高い材料を使用する必要があった。また、従来にあっては高さ調整用の軸部３’に対してフロアーパネル４’は直接連結してないので、パネル受け部５’と軸部３’とを強固に連結することも必要となる。
【０００４】
【発明が解決しようとする課題】
本発明は、上記の従来例の問題点に鑑みて発明したものであって、その目的とするところは、ロック部によりパネル受け部に載置したフロアーパネルの角部を固定するに当たり、ロック部を軸部に直接固定することで、パネル受け部に雌ねじ部を形成する必要がなくて従来のようにダイキャストのような高コストの材料を必要とせず、また、フロアーパネルと軸部との一体化が向上して歩行感、耐久性が向上し、更に、フロアーパネルの角部をパネル受け部に載置した後にロック部の軸部を軸部の雌ねじ部に螺合するに当たって雌ねじ部が見つけやすくて螺合が簡単にできるフロアーパネルの支持具を提供することを課題とするものである。
【０００５】
【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に係るフロアーパネルの支持具は、スラブのような床下地１に載設するための取付けベース２と、取付けベース２から立設された軸部３と、軸部３上端に設けられてフロアーパネル４の角部分を載置するためのパネル受け部５と、パネル受け部５中央に配設されてフロアーパネル４の角部を固定するためのロック部６とを備えたフロアーパネル４の支持具７において、取付けベース２に立設した高ナット１３に軸部３を螺合し、パネル受け部５を、軸部３の上端に取付けられる略平板状の鋼板からなる鋼板ベース１１と、鋼板ベース１１の上面側に被着される樹脂材よりなる樹脂カバー１２とで構成し、樹脂カバー１２の中央部に上方に向けて中央突部２０を突設し、中央突部２０の上面部の中央部に孔２１を設け、孔２１の周囲がフロアーパネル４の角部先端を載置するための載置部２２となり、軸部３の中心部に上方に開口する雌ねじ部８を形成し、ロック部６に上記樹脂カバー１２の中央部の孔２１から挿入して軸部３に設けた雌ねじ部８に螺合するための雄ねじ部９を設けると共に、ロック部６に載置部２２の上に載置したフロアーパネル４の角部先端を押圧して固定するための押さえ板２３を設けて成ることを特徴とするものである。このような構成とすることで、軸部３を高ナット１３に対して回転することで支持具７の高さ調整をした状態で、パネル受け部５の樹脂カバー１２に設けた載置部２２にフロアーパネルを載設し、ロック部６の雄ねじ部９を軸部３に設けた雌ねじ部８に直接螺合してフロアーパネル４の角部を固定できて、パネル受け部５に載置したフロアーパネル４の角部をロック部６により軸部３に一体に固定できてフロアーパネル４と軸部３とが確実に固定され、また、ロック部６の雄ねじ部９を螺合するための雌ねじ部８を軸部３に形成し、更に、パネル受け部５を、軸部３の上端に取付けられる略平板状の鋼板からなる鋼板ベース１１と、鋼板ベース１１の上面側に被着される樹脂材よりなる樹脂カバー１２とで構成し、樹脂カバー１２の中央部に上方に向けて中央突部２０を突設し、中央突部２０の上面部の中央部に孔２１を設け、孔２１の周囲がフロアーパネル４の角部先端を載置するための載置部２２としたので、パネル受け部５として、従来のように雌ねじ部８を形成したダイキャスト製の高コストのものとする必要がない。
【０００６】
また、軸部３の上端部の中心部近傍に凹部１０を設けることが好ましい。このような構成とすることで、フロアーパネル４の角部をパネル受け部５に載置した後にロック部６の雄ねじ部９を軸部３の雌ねじ部８に螺合するに当たって雌ねじ部８が見つけやすくて螺合が簡単にできるものである。
【０００７】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【０００８】
フロアーパネル４を支持する支持具７は、図１、図２に示すようなもので、床スラブのような床下地１に載設される取付けベース２と、取付けベース２から立設された軸部３と、軸部３の上端に固定されたパネル受け部５と構成されている。パネル受け部５は、軸部３の上端に取り付けられる略平板状の鋼板からなる鋼板ベース１１と、鋼板ベース１１の上面側に被着される平面視略円形状の樹脂材からなる樹脂カバー１２とで構成されている。
【０００９】
軸部３は外周に形成した雄ねじ１４を取付けベース２に立設した高ナット１３の雌ねじ１５に螺合することで取付けベース２から上方に立設してあり、この軸部３の上部に鋼板ベース１１を固定するには例えば、図７に示すように軸部３上端部にフランジ部３ａを設け、中央部に孔があいた鋼板ベース１１をフランジ部３ａに載置した状態で軸部３上端部のカシメ部３ｂを鋼板ベース１１の孔の周囲にカシメ固定することで固定してある。軸部３には上方に向けて開口するねじ孔よりなる雌ねじ部８が設けてあり、軸部３の上端部の中心部近傍には凹部１０が形成してあり、図８に示す実施形態では軸部３の上端部の雌ねじ部８の開口の周囲に凹部１０が形成してある。また、軸部３には固定レバー１６に設けた固定ナット１７が螺合してある。
【００１０】
樹脂カバー１２の外周側の４箇所には嵌合突部１８が突設されている。嵌合突部１８は上方に突出しており、後述のフロアーパネル４の嵌合孔１９が嵌合可能となっている。嵌合突部１８の上端部には、嵌合突部１８を嵌合孔１９に誘導するための傾斜部１８ａが設けてある。また、樹脂カバー１２の中央部には上方に向けて中央突部２０が突出してあり、中央突部２０の上面部の中央部に孔２１が設けてあり、中央突部２０の上面部の孔２１の周囲が後述のフロアーパネル４の角部先端を載置するための載置部２２となっている。
【００１１】
また、上記パネル受け部５の鋼板ベース１１の中心部分は、軸部３に近接する程下方に傾斜するように凹状に形成されている。
【００１２】
さらに、図６に概略的に示すように、パネル受け部５の鋼板ベース１１には係合孔３５が設けてあり、樹脂カバー１２には係合孔３５に係合する係合突起３６が設けてあり、係合突起３６を係合孔３５に係合することで鋼板ベース１１に対する樹脂カバー１２の回転を止めこれにより鋼板ベース１１と樹脂カバー１２とが一体に回動するようになっている。
【００１３】
ロック部６は押さえ板２３の中央部にねじ棒状の雄ねじ部９を下方に向けて垂下して構成してある。ねじ棒状の雄ねじ部９としては市販のねじを採用することができる。この雄ねじ部９は樹脂カバー１２の中央の孔２１から挿入して下端部を上方に開口した雌ねじ部８に螺合自在としてある。
【００１４】
一方、フロアーパネル４は、図３に示すように天板２６と底板２７との二重構造を有している。底板２７には、天板２６の下面に向かって断面逆Ｕ字状に湾曲した凸部２８が縦横に複数形成されており、各凸部２８の頂部が天板２６の下面の複数箇所にそれぞれカシメによって固着一体化されている。底板２７の四隅には、それぞれ、上下方向に開口した嵌合孔１９が形成されており、４つの嵌合孔１９の内部に前記した支持具７のパネル受け部５に設けた４つの嵌合突部１８が個別に嵌合可能となっている。また天板２６の嵌合孔１９との対向位置には、嵌合孔１９よりも小径の嵌合確認用の開口部２９が設けられている。
【００１５】
上記フロアーパネル４の底板２７の外周部には、天板２６の外周部の下面に向かって垂直に立ち上がる立ち上がり部３０が立設されていると共に、立ち上がり部３０の上端部から外側方に向かって先端が段落ちしたフランジ部３２が突設されており、一方、天板２６の外周部には先端が段落ちしたフランジ部３１が突設されており、底板２７のフランジ部３２は天板２６のフランジ部３２の下面にカシメによって固着一体化されている。さらに、天板２６及び底板２７のフランジ部３１、３２の四隅部（つまりフロアーパネル４の各角部）には、それぞれ、平面視で略円弧状をした切欠部３３が切欠形成されており、この切欠部３３を有する各角部の先端部が前述の支持具７の載置部２２に載置され、ロック部６の押さえ板２３により押さえられて固定されるようになっている。
【００１６】
しかして、図４、図５に示すように、床スラブのような床下地１に複数の支持具７の取付けベース２を載設し、支持具７は軸部３を高ナット１３に対して回転することで高さ調整をする。高さ調整が完了すると固定レバー１６を回転して固定ナット１７を高ナット１３に対して圧接することでいわゆる２重ナット状態で固定する。上記のように床下地１に載設し且つ高さ調整を行った支持具７にフロアーパネル４を載設支持して固定することで２重床を構成するものである。
【００１７】
この場合、フロアーパネル４の四隅部（つまり４つの角部）をそれぞれ支持具７に支持するものである。すなわち図４、図５に示すように、フロアーパネル４の角部をパネル受け部５に載設した場合、フロアーパネル４の角部に設けた嵌合孔１９がパネル受け部５に設けた嵌合突部１８に嵌合されて位置決めされるものであり、嵌合孔１９に嵌合突部１８を嵌合して位置決め状態にあるか否かは嵌合確認用の開口部２９から目視して確認することができるものである。このようにして一つの支持具７のパネル受け部５に図５に示すように４枚のフロアーパネル４の角部をそれぞれ載置してフロアーパネル４の角部に設けた各嵌合孔１９を対応する嵌合突部１８に嵌合することでそれぞれ位置決めするものである。
【００１８】
ここで、一つの支持具７に上記のように４つのフロアーパネル４の各角部先端の略円弧状をした切欠部３３により円孔が形成されることになるので、この円孔からロック部６のねじ棒状の雄ねじ部９を挿入し、雄ねじ部９を樹脂カバー１２の中央の孔２１を挿通して下端部を上方に開口した雌ねじ部８に螺合し、ロック部６は押さえ板２３により支持具７に載置した４枚のフロアーパネル４の角部の先端部を押圧することで４枚のフロアーパネル４の角部を固定してある。
【００１９】
上記のようにしてフロアーパネル４の角部をロック部６により固定する際、軸部３の上端部の中心部近傍に凹部１０を設けてあるので、４つのフロアーパネル４の各角部先端の略円弧状をした切欠部３３により囲まれた円孔から下方を覗いた場合に凹部１０が見えるため容易に雌ねじ部８の開口を探すことができ、また、ねじ棒状の雄ねじ部９の先端部が凹部１０にガイドされてスムーズに雌ねじ部８に導入されて簡単に螺合できるものである。
【００２０】
このようにしてロック部６の雄ねじ部９を軸部３の雌ねじ部８に螺合してフロアーパネル４の角部を固定することで、パネル受け部５に載置したフロアーパネル４の角部をロック部６により軸部３に一体に固定でき、歩行感、耐久性が向上するものである。また、軸部３に雌ねじ部８を設けてロック部６の雄ねじ部９を螺合するので、従来のようにパネル受け部５に雌ねじ部を設ける必要がなく、したがって、パネル受け部５を従来のように高価なダイキャスト製とする必要がなく、コストの低い材料で形成できるものである。
【００２１】
