Description

【０００１】
【発明の属する技術分野】
本発明は、屋外デッキ等に用いられる床緩衝支持具に関する。
【０００２】
【従来の技術】
従来、図８に示す木製デッキの床構造が知られている。この床構造に用いられる床支持具５１は、コンクリートの床スラブ１１に立設される支持ボルト５３の上部に、円板状の受け部５４を固定したものである。この受け部５４の下部側には、支持ボルト５３に螺着されたナット５５が配置され、このナット５５により高さが調整される。一方、受け部５４は、その上部側に座がね５６を介してナット５７が締結され支持ボルト５３の所定位置に固定されている。
【０００３】
上記床支持具５１は、所定間隔をおいて床スラブ１１に立設され、これら床支持具５１の受け部５４に、ゴム板５８を介して根太鋼５９を所定間隔を隔てて載置する。これら根太鋼５９は、その左右のフランジ部がビス４４で上記受け部５４に固定される。この根太鋼５９の上部に硬質木製の床板４１を直角方向に配置し、固定金具４３を用いて、その翼片４５を床板４１の側面に設けられた溝部４２に係止し、さらに固定金具４３の基部を根太鋼５９にビスで固定する。同様にして、順次床板４１を各床板４１間に所定の隙間を設けて敷設し、床構造を形成する。
【０００４】
【発明が解決しようとする課題】
上記床支持具５１は、上記ゴム板５８を介在させているものの、このゴム板５８は板厚が薄く、弾性効果を持たず、受け部５４と根太鋼５９との接触軋み音の発生防止のために設けられている。このため、表面材としての床板４１が硬質であることも手伝って、床構造全体としては硬い床組みになっている。このように、従来の屋外デッキは強度面は重視されるものの、床の衝撃等の安全面に関する配慮に欠け、また、根太鋼５９を受け部５４に固定してしまうと高さレベルの微調整が行えない、という問題があった。
【０００５】
本発明は上記問題点に鑑みてなされたものであり、強度及び衝撃緩和に優れ、かつ施工性の良い床緩衝支持具を提供することを目的とする。
【０００６】
【課題を解決するための手段】
以上の技術的課題を解決するため、本発明に係る床緩衝支持具は、図１及び図２に示すように、床スラブ１１に立設される支持ボルト６と、この支持ボルト６に螺合され、下部に鍔部１２が設けられた筒状ナット３と、この筒状ナット３に挿通されるとともに、下部が上記鍔部１２に支持される弾性体２と、上記支持ボルト６に挿通され、上記弾性体２の上部に配置される一方、根太７を載置固定する受プレート１と、上記筒状ナット３の上部に嵌合固着される固定具４と、を有する構成である。
【０００７】
本発明に係る床緩衝支持具は、上記筒状ナット３は上記弾性体２を介して、上記受プレート１に対して回転可能に嵌め合わされる構成である。
【０００８】
本発明に係る床緩衝支持具は、上記弾性体２には、基部２４に上記支持ボルト６の挿通孔２０が設けられ、この基部２４上面部に、挿通孔２０の側壁を筒状に上方に延長してさらに外向きに屈曲した鍔状部１７及びこの鍔状部１７に伴う環状の溝部１６が形成され、上記溝部１６に上記受プレート１に設けられた孔部１４を弾性係合させた構成である。
【０００９】
【発明の実施の形態】
以下、本発明に係る床緩衝支持具の実施の形態を図面に基づいて説明する。
図１は、上記床緩衝支持具１０を示す図である。この床緩衝支持具１０は、防振板９を介して根太７を支持する受プレート１、この受プレート１を弾性支持する弾性体２、雄ねじが刻設された支持ボルト６、この支持ボルト６と螺合する鍔部１２付きの筒状ナット３、この筒状ナット３の上部に嵌合固着される六角形状の固定具４、及び六角ナット５を有している。
【００１０】
図２に示すように、上記受プレート１はステンレス鋼からなり、中央には孔部１４が設けられた中空円板状で、周囲には下方に向けて屈曲された環状のフランジ１５が形成されている。上記弾性体２は、ゴム或いは合成樹脂製の弾性材からなり、円柱状の基部２４の中央部には上下に挿通孔２０が設けられ、上面部２２には挿通孔２０の側壁を筒状に上方に延長してさらに外向きに屈曲した鍔状部１７が形成され、この鍔状部１７と上面部２２との間には、水平な環状の溝部１６が形成されている。
【００１１】
上記筒状ナット３は、所定の板厚の円筒状の筒部２１の内周面に雌ねじ１９が刻設され、下端部は拡径されて外形が六角形の六角部１８が形成され、この六角部１８の上部には中空円板状の鍔部１２が嵌合固定されている。固定具４は、外形が六角形で、中央部上下に円形の嵌合孔１３が形成されている。これら、筒状ナット３、鍔部１２、及び固定具４は、いずれもステンレス鋼材からなっている。
【００１２】
上記防振板９はゴム或いは合成樹脂性の弾性材からなり、中央に円形の孔部２５が形成された長方形状の板材で、長手方向の端部には少し立上がった部位から内向きに屈曲形成された係合部２６が形成されている。根太７は鋼製で、断面ハット形状の長尺材であり、天板部３３の両側から下方に屈曲して側板部３４が形成され、これら側板部３４からそれぞれ外向きにフランジ部３５が形成されている。
【００１３】
上記床緩衝支持具１０の筒状ナット３には、図３に示すように、その筒部２１に弾性体２の挿通孔２０が嵌め込まれる。この弾性体２の溝部１６には、受プレート１の孔部１４が弾性体２の弾性を利用して弾性係合され、弾性体２の上面部２２に受プレート１の下面部２３が当接する。この弾性体２に対して、受プレート１は回転可能に支持される。
【００１４】
さらに、受プレート１から上方に突出した筒状ナット３の上部には、固定具４が固く嵌合固定される。この固定具４により、弾性体２及び受プレート１を緩みなく安定して筒状ナット３に保持し、高さ調整時にも受プレート１を正確に移動させる。そして、筒状ナット３の筒部２１は弾性体２の挿通孔２０に摺接し、弾性体２に対して、筒状ナット３及びこれに固定された固定具４は回転可能に支持される。このような受プレート１の取付け形態により、受プレート１には、弾性体２の肉厚の基部２４の弾性力が作用する形態となり、大きな緩衝効果が得られる。
【００１５】
また、弾性体２の一部である鍔状部１７が、受プレート１の上面部と固定具４の下面部との間に介在する形態であることから、固定具４の下面部が直接受プレート１に当たることはなく、併せて、弾性体２の溝部１６の介在により、受プレート１の孔部１４と筒状ナット３とが直接当たることはないので、それぞれ音鳴りが防止される。
【００１６】
さらに図４及び図５に示すように、支持ボルト６に六角ナット５を螺合し、この上から、上記筒状ナット３を受プレート１とともに支持ボルト６に螺合し、六角ナット５の上部で筒状ナット３を締結する。一方、支持ボルト６に、下方から雌ねじが刻設された中空円板状のベース板２８を螺合する。
【００１７】
上記床緩衝支持具１０を床スラブ１１に設置する場合には、図１に示すように、床スラブ１１に設けた穴部２７に接着材を注入して、この穴部２７に床緩衝支持具１０の支持ボルト６の下部を埋設接着し、併せて支持ボルト６に螺合したベース板２８を上記接着材で床スラブ１１の表面部に接着する。
【００１８】
図６及び図７は、上記床緩衝支持具１０を、屋外又は屋内に敷設される木製デッキの床構造に用いた例を示している。この床構造は、コンクリートの床スラブ１１に床緩衝支持具１０を所定箇所に配置立設し、これら床緩衝支持具１０の受プレート１に根太７を所定間隔を隔てて互いに平行に支承する。このとき、受プレート１の上部に防振板９を、その孔部２５を受プレート１から突出する固定具４に嵌めて配置し、この防振板９を介在させて受プレート１に根太７を載置する。この根太７のフランジ部３５にセルフドリリング可能なビス８をねじ込み、根太７を受プレート１に締結する。
【００１９】
根太７の設置の後、ジャラ等の硬質木製の床板４１を根太７と直角方向に配置する。この床板４１の取付けには、基部から立ち上がる立設部の上部に左右に翼片４５が形成された固定金具４３を用いる。施工の手順としては、根太７の端には、翼片が一方のみに形成された端部用の固定金具４６をビス４４を用いて固定する。そして、この端部固定金具４６の翼片に床板４１の一端側の溝部４２を係止する一方、固定金具４３を用い、床板４１の他方側の溝部４２にこの固定金具４３の一の翼片４５を係止させるとともに、この固定金具４３の基部をビス４４を用いて根太７に固定する。次に、別の床板４１を固定金具４３の他の翼片４５に係止させる、という作業を順次行い、併せて各床板４１間に所定の隙間を設けて床板４１を敷設し、床構造を形成する。
【００２０】
上記実施の形態に係る床緩衝支持具１０を用いた床構造について、この床上での転倒時等に発生する緩衝を測定した。この測定に際しては、ＪＩＳＡ６５１９規格の「体育館床下地材」に基づき、床の硬さを測定した。この結果、従来（当社製品）の、屋外デッキの床支持具（緩衝機構なし）を用いた床では、硬さ試験結果が、床板（ジャラを使用）の板厚が２０ｍｍのものでは１０３Ｇ〜１０４Ｇ、板厚が３０ｍｍのものでは１０１Ｇ〜１０２Ｇであり、これは体育館床の基準とされている１００Ｇを越えるもので、かなりの硬さである。
【００２１】
一方、上記実施の形態に係る床緩衝支持具１０を用いた床では、同様の硬さ試験結果が、同床板の板厚が２０ｍｍのものでは７６Ｇ〜７７Ｇ、板厚が３０ｍｍのものでは８６Ｇ〜８７Ｇであった。この結果、上記床緩衝支持具１０を用いた場合には、床をかなり柔らかくすることができ、これにより、衝撃の緩和が図れ、床上における転倒時等の体への衝撃の負担が軽減される。
【００２２】
従って、上記実施の形態に係る床緩衝支持具１０によれば、筒状ナット３等の採用により、床支持具として強度が確保され、併せて弾性体２を設けた形態を採用したから、これを屋外或いは屋内のデッキとして使用した場合には、床上の衝撃緩和が図れ、例えば高齢者等の転倒時の安全性が確保され、高齢者対応の床構造として有効である。また、床緩衝支持具１０は、受プレート１に対して筒状ナット３が回転可能なため、受プレート１に根太７をビス８で固定した後でも、六角ナット５を緩め、筒状ナット３の六角部１８を工具を回転操作することで、根太７と受プレート１との結合を解除することなく高さのレベル微調整が出来る。また、弾性体２の一部である鍔状部１７が受プレート１の上部に延設されているので、固定具４及び筒部２１と受プレート１との接触が妨げられ音鳴りが防止できる。
【００２３】
【発明の効果】
以上説明したように、本発明に係る床緩衝支持具によれば、支持ボルトに螺合され鍔部が設けられた筒状ナット、この筒状ナットに挿通されるとともに鍔部に支持される弾性体、及び弾性体の上部に配置される一方、根太を載置固定する受プレート、筒状ナットに固着される固定具を有する構成を採用したから、床緩衝支持具としての強度が確保されるとともに、緩衝効果が高く床上での転倒時の安全性が確保され、高齢者対応の床構造としても有効である、という効果を奏する。
【００２４】
また、本発明に係る床緩衝支持具によれば、筒状ナットは弾性体を介して、受プレートに対して回転可能に嵌め合わされる構成としたから、受プレートに根太を固定した後でも、筒状ナットを回転操作することで高さの微調整が行え、施工性がよいという効果がある。
【００２５】
本発明に係る床緩衝支持具によれば、弾性体の基部上面部に鍔状部及び溝部が形成され、溝部に受プレートを弾性係合させた構成としたから、筒状ナット及び固定具と受プレートとの接触が妨げられ音鳴りが防止できるという効果がある。
