【産業上の利用分野】
本発明は、細長い床材を根太材を介してコンクリートスラブ（テラスや建物内に）上に敷設するために用いる床材の敷設装置に関するものである。
【０００２】
【従来の技術】
例えば、特許第２８７７７９４号公報所載のように床材の側端面に設けた溝に根太材側に固着した結合金具の係止部片を係合するようにして床材を敷設する構造のものがある。
【０００３】
【発明が解決しようとする課題】
前記従来例は、結合金具の係止部片を床材の側端面に設けた溝に係合する構成を採るため、結合金具の根太材に対する固着作業と、結合金具と床材との結合作業が絡み合い作業性が悪い。
【０００４】
本発明は、敷設作業を円滑に行え、しかも、安定した床材の敷設状態を得られる、斬新な構造の床材の敷設装置を提供すべく創案したものである。
【０００５】
【課題を解決するための手段】
下部を根太材に組付けた接合駒を根太材上に立設し、該接合駒の両側に配して互いに隣接する一対の床材を前記根太上に敷設し、該床材の、切欠状の凹入部を設けて一段低くした側端部上に端部を載置した押え片の中央部を、前記接合駒に結合手段によって結合すると共に、套装材を、押え片の前記中央部に組付けて該端部を前記凹入部に係合した構成とする。
【０００６】
【発明の実施の形態】
図面は本発明に係る床材の敷設装置の実施形態を示し、図１は縦断面図、図２は図１の縦断面図、図３は接合駒と押え片の関係を示す分解斜視図、図４は第二実施形態の縦断面図、図５は図４の縦断面図、図６は第二実施形態の、接合駒と押え片の関係を示す分解斜視図である。
【０００７】
実施形態は、アルミ押出し形材より成る根太材１をコンクリートスラブ（図示省略）上に並設し、該根太材１に摺嵌した接合駒２と押え片３を用いて床材４を前記根太材１に組付け、押え片３を套装材５で套装するようにして床材４の敷設状態を得るものである。
【０００８】
前記根太材１は、断面方形状の中空主体６の上下の部片６ａ，６ｂのそれぞれに中空主体６の長手方向に沿って相対する上下それぞれ一対のＬ形部片７，７、８，８を突設して構成し、上Ｌ形部片７，７と前記上部片６ａとで構成する上側の係合溝９に前記接合駒２を基板１０において摺嵌して組付け、下Ｌ形部片８，８と前記下部片６ｂとで構成する係合溝１１に図示省略したナット材を摺嵌して組付け、該ナット材に図示省略した受支ボルトを螺合して受支ボルトに受支させて前記コンクリートスラブ上に少くも一対並設するようにしたものである。
【０００９】
前記接合駒２は、方形状の前記基板１０の上面中央に接合部片１２を立設して構成し、下部側である前記基板１０を、根太材１に設けた上側の係合溝９に摺嵌して組付けて接合部片１２部を前記根太材１上に立設したものである。
【００１０】
この接合駒２の両側に配して前記根太材１上に（少くも一対の根太材１，１に架設するように）敷設した一対の床材４，４は、上部側を切欠状として凹入部１３を設けて上面を他の部分より一段低くした側端部４ａをその長手方向に沿う両側に備え、該側端部４ａの上面の側端に突条１４を設けた木製素材で構成したものである。
【００１１】
押え片３は、端部３ａを凹入部１３に係合するようにして接合駒２を介して相隣接する床材４の側端部４ａ上に載置し、中央部を結合手段（第一、第二の実施形態はこの点に於いて異なる）によって接合駒２（接合部片１２）に結合するようにして前記側端部４ａを前記根太材１とで挟持するものである。
【００１２】
そして、押え片３は主体部片１５の下面両端に床材４の前記側端部４ａ上に載置して、床材側端部４ａ側の前記突条１４と水平方向に重なり合う突縁１６を設け、上面中間部には一対の嵌入部片１７，１７を立設して構成したものである。
【００１３】
この押え片３の嵌入部片１７に套装材５の下面側に設けたスリット１８を圧入させるようにして套装材５を押え片３に組付けて前記凹入部１３，１３内に係合して実施例に係る床構造とする。
【００１４】
套装材５は、床材４と同様に木材を素材とし、実施形態では、この套装材５と床材４の上面が同面上にあるが、套装材５側が床材４側に対して高く或いは低くとも差し支えはない（もっとも程度の問題ではあるが）。
【００１５】
実施形態の場合は、床材４と套装材５が同長で、これらの長手方向に沿って点在的に接合駒２及びこれに結合した押え片３が存することになるが（接合駒２と押え片３は根太材１１位置にあり、根太材１の長手方向に沿って床材４の幅員間隔を置いて存することになる）、該接合駒２等のない個所の、床材４端部と套装材５とで形成される隙間は、屋外であるテラスの床装置に用いたとき雨水の排出口となる。
【００１６】
しかして、コンクリートスラブ上に所要間隔を存して配設した根太材１上に床材４を載置し、該床材４の側端に前記根太材１に予め摺嵌した接合駒２を隣接させ、次段の他の床材４を根太材１上に載置して接合駒２に隣接させ、次いで、押え片３を根太材１，１間に存する接合駒２上に載置し、かつ、その両端を床材側端部４ａ上に重ね合わせ、結合手段によって押え片３の主体部片１５の中央部を接合駒２（接合部片１２）に結合して、嵌入部片１７とスリット１８を用いて套装材５を押え片３に組付け、かつ、床材４の凹入部１３にその端部側を係合するようにして、順次床材４を敷設することにより床材の敷設状態を得られる。
【００１７】
図１乃至図３で示す第一実施形態の接合駒２は、接合部片１２の上面中央に挟入切込み１９を設ける（接合部片１２を上端間に空隙を設けた一対の部片で構成し）一方、押え片３の主体部片１５の下面中央に嵌入部片２０を設け、該嵌入部片２０を挟入切込み１９に強制的に挟入して接合部片１２を弾性変形させてその先端２０ａを接合部片１２内に係合して押え片３と接合駒２を接合するような結合手段を用いたもので、床材４の側端面を接合駒２すなわち接合部片１２の接合面に接触させた方が（図１においては隙間があるが）接合部片１２の弾性変形を規制し、従って、挟入切込み１９の拡径がむずかしくなり、より強固な床材の敷設状態を得られる。
【００１８】
図４乃至図６で示す第二実施形態は、中空の接合部片１２の上部分に螺子孔２１を設け、該螺子孔２１に押え片３の主体部片１５中央に設けた透孔２２を通じて締付ねじ２３を螺合締付けることにより押え片３を接合駒２すなわち接合部片１２に結合するようにして結合手段としたもので、套装材５の下面には締付ねじ２３の頭部の逃げ溝２５を設けてある。
【００１９】
なお、床材４の側端部４ａ上面に突条１４を設け、この突状１４の内側に押え片３側の突縁１６を配してこれらを床材４の並設方向に重ね合わせてあるのは、これら両部１４，１６が係止し合って床材の、当初の（設計通りの）敷設状態を尚一層維持させるものである。
【００２０】
【発明の効果】
本発明は前記の通りの構成であるから、押え片と根太材とで床材を挟持して当初の敷設状態を維持した床材の敷設状態を得られ、しかも、套装材で押え片を套装した状態の床材敷設状態を得られるから各部材の組付け関係が外部から判りにくい、斬新な構造の敷設装置を提供できる。
