【発明の属する技術分野】
本発明は、外壁パネルを並べて取り付けたとき隣り合う外壁パネルの側端間を防水シールする構造に関するものである。
【０００２】
【従来の技術】
従来、パネル本体の表面側に外装材を貼った外壁パネルを外壁パネルの側端面同士が対向するように並べて立設して隣り合う外壁パネルの側端間を防水する場合、隣り合う外壁パネルの外装材の側端間に目地部材を介装し、この目地部材の両側のシール片を外装材の側端に弾接している（例えば、特許文献１参照）。

【０００４】
【発明が解決しようとする課題】
ところが、上記従来例では目地部材の両側のシール片を外装材の側端に弾接しているだけのためにこの部分で一重にしかシールできなく、シール片の部分を越えて水が浸入すると、パネル本体側に水が浸入するおそれがある。
【０００５】
本発明は上記の点に鑑みてなされたものであり、内部に水が浸入するのを確実に防止できる外壁パネルの防水接続構造を提供することを課題とするものである。
【０００６】
【課題を解決するための手段】
上記課題を解決するための本発明の外壁パネルの防水接続構造は、パネル本体１の表面側に外装材２を貼った外壁パネルＡを外壁パネルＡの側端面同士が対向するように並べて立設し、外壁パネルＡの側端で外装材２の側端縁の裏側に側端が開口せる縦凹溝３を上下方向に亙って凹設し、縦片４ａと横片４ｂとからなる断面略逆Ｔ字状の目地部材４を隣り合う外壁パネル間Ａに上下全長に亙るように配置して隣り合う外壁パネルＡの外装材２の側端間に上記縦片４ａを配置すると共に上記横片４ｂの両側を隣り合う外壁パネルＡの縦凹溝３に位置させ、上記縦片４ａの先端から長手方向全長に亙って両側に突設した外側シール片５を夫々隣り合う外壁パネルＡの外装材２の側端に弾接し、上記横片４ｂの両側から長手方向全長に亙って表面側に突設した内側シール片６を夫々隣り合う外壁パネルＡの外装材２の側端部の裏面に弾接した外壁パネルの防水接続構造であって、上記外壁パネルＡは、隣り合う外壁パネルＡの側端面間に所定の間隙を隔てるように立設されると共に、上記目地部材４に押圧用凹部１３を設け、屋内側より隣り合う外壁パネルＡの側端面の間の隙間から上記押圧用凹部１３を押すことで、上記外側シール片５が外装材Ａの側端に弾接し上記内側シール片６が隣り合う外装材Ａの側端部の裏面側に弾接するように構成したことを特徴とする。上記のように構成したことにより、隣り合う外壁パネルＡの側端面間に所定の間隙を隔てるように外壁パネルＡを立設して、屋内側より隣り合う外壁パネルＡの側端面の間の隙間から目地部材４の押圧用凹部を押すだけで、上記外側シール片５が外装材２の側端に弾接し、上記内側シール片６が外装材２の側端部の裏面側に弾接するようになる。これにより、外側シール片５の外装材２の側端面への弾接と内側シール片６の外装材２の側端部の裏面への弾接にて二重にシールできてパネル本体１側に水が浸入するのを確実に防止できる。たとえ外側シール片５を越えて水が浸入しても目地部材４の縦片４ａや横片４ｂと外装材２にて囲まれた空間を通って下方に流れて外部に排出され、パネル本体１の方に水が浸入するのを確実に防止できる。
【０００７】
また本発明の外壁パネルの防水接続構造は、外壁パネルＡは、隣り合う外壁パネルＡの側端面間に所定の間隙を隔てるように立設されると共に、隣り合う外壁パネル間に上下全長に亙るように配置した目地部材４に掴み突部１５を設け、屋内側より隣り合う外壁パネルＡの側端面の間の隙間から上記掴み突部１５を屋内側に引っ張ることで、目地部材４の縦片４ａの先端から長手方向全長に亙って両側に突設した外側シール片５が外装材２の側端に弾接し、目地部材４の横片４ｂの両側から長手方向全長に亙って表面側に突設した内側シール片６が外装材２の側端部の裏面側に弾接するように構成したことを特徴としている。上記のように構成したことにより、屋内側より隣り合う外壁パネルＡの側端面の間の隙間から掴み突部１５を屋内側に引っ張ることで、外側シール片５が外装材２の側端に弾接されると共に内側シール片６が外装材２の側端部の裏面側に弾接されることにより二重にシールされてパネル本体１側に水が浸入するのが防止される。
【０００８】
また金属のチャンネル材からなる縦溝材７を外壁パネルの縦凹溝３の内面に沿うように装着して成ることを特徴とすることも好ましい。このようにすることで一層水がパネル本体１の方に浸入するのを防止できる。
【０００９】
また外壁パネルＡの下端で外装材２の下端の裏側に下端が開口せる横凹溝８を左右方向に亙って凹設すると共に上記縦凹溝３の下端を横凹溝８に連通させ、縦片部９ａと横片部９ｂとからなる断面略Ｌ字状の止水部材９を外壁パネルＡの下方に外壁パネルＡの左右方向と平行に装着すると共に止水部材９の縦片部９ａを縦片部９ａが目地部材４より裏側に位置するように横凹溝８内に挿入したことを特徴とすることも好ましい。この場合、目地部材４と外装材２との空間を通って下に流れてきた水が止水部材９の縦片部９ａにてパネル本体１側に行かず、止水部材９を介してスムーズに外部に排水される。
【００１０】
また横凹溝８の上底面に水密材１０を左右方向に亙るように装着すると共に止水部材９の縦片部９ａの上端を水密材１０に圧接したことを特徴とすることも好ましい。この場合、止水部材９の縦片部９ａを越えてパネル本体１の方に水が浸入するのを一層確実に防止できる。
【００１１】
【発明の実施の形態】
図１に示すように外壁パネルＡはパネル本体１の表面側に窯業系の外装材２を貼着して形成されている。パネル本体１は木材等で形成せる枠組に断熱材を充填し、必要に応じて裏面側に内装下地材を貼って形成されている。外装材２の表面側の周縁に面取り１１を設けてある。外壁パネルＡの両側の側端には外装材２の側端縁の裏側の位置で側方に開口せる断面略コ字状の縦凹溝３を上下全長に亙って凹設してある。この縦凹溝３には鋼板のような金属のチャンネル材からなる縦溝材７を内面に沿うように装着してある。
【００１２】
図１に示すように目地部材４はゴム、合成樹脂等の弾性材料にて長尺物に形成されるものであり、縦片４ａと横片４ｂを主体とした断面略逆Ｔ字状に形成されている。本例の場合、縦片４ａ及び横片４ｂの内部に鋼板のような金属板の芯材１２を内装してある。縦片４ａの先端には長手方向に亙って両側に突出するように外側シール片５を突設してある。この外側シール片５は先端ほど横片４ｂの方に行くように傾斜させてある。横片４ｂの両側には長手方向に亙って表面側に突出するように内側シール片６を突設してある。この内側シール片６は先端ほど縦片４ａの方に行くように傾斜させてある。本例の場合、内側シール片６は横片４ｂの両側に２条づつ設けてあり、第１内側シール片６ａと第２内側シール片６ｂとを有している。横片４ｂの幅方向の中央には押圧用凹部１３を長手方向全長に亙って凹設してある。
【００１３】
上記外壁パネルＡは左右に並べて立設されるのであるが、隣り合う外壁パネルＡの側端面間に所定の間隙を隔てるように立設される。この外壁パネルＡを立設するとき、図１（ａ）に示すように隣り合う外壁パネルＡの縦凹溝３に目地部材４の両側を収納しておく。そして屋内側から隣り合う外壁パネルＡの側端面の間の隙間に押し治具１４を挿入し、押し治具１４の先端を押圧用凹部１３に当接し、押し治具１４で目地部材４を押して目地部材４の縦片４ａを隣合う外壁パネルＡの外装材２の側端面間に圧入する。これにより図１（ｂ）に示すように外側シール片５は外装材２の側端面に弾接され、内側シール片６は縦凹溝３で外装材２の側端部の裏面側に弾接される。
【００１４】
このように外側シール片５が外装材２の側端面に弾接されると共に内側シール片６が外装材２の側端部の裏面に弾接されることにより二重にシールされてパネル本体１側に水が浸入するのが防止される。このとき、外側シール片５を越えて水が浸入しても目地部材４の縦片４ａや横片４ｂと外装材２の側端部との間の空間を通って下方に流れて外部に排水される。また内側シール片６は第１内側シール片６ａと第２内側シール片６ｂとで構成され、第１内側シール片６ａと第２内側シール片６ｂを外装材２の裏面に弾接しているため、内側シール片６の部分でも二重にシールできて一層パネル本体１の方に水が浸入するのを防止できる。また縦凹溝３に金属の縦溝材７を設けてあることでもパネル本体１の方に水が浸入するのを一層防止できる。
【００１５】
図２は他の例を示すものである。本例も上記例と基本的に同じであり、異なる点だけを主に述べる。本例の場合も、目地部材４は縦片４ａと横片４ｂとからなる断面略逆Ｔ字状に形成されている。本例の場合、金属板の芯材１２は縦片４ａに主に内装してある。横片４ｂが両側に行くほど、厚さが厚くなるように断面中空三角形状に形成されている。縦片４ａの先端には両側に突出する外側シール片５を長手方向全長に亙って設けてあり、横片４ｂの両側には両側に突出するように内側のシール片６を長手方向全長に亙って設けてある。横片４ｂの裏面の中央から断面逆Ｔ字状の掴み突部１５を長手方向の全長に亙って突設してある。
【００１６】
外壁パネルＡは左右に並べて立設するとき、図２（ａ）に示すように隣り合う外壁パネルＡの縦凹溝３に目地部材４の横片４ｂの両側を挿入し、隣合う外壁パネルＡの外装材２の側端間に縦片４ａを位置させると共に外装材２の面取り１１間に外側シール片５を位置させておく。そして屋内側から隣り合う外壁パネルＡの側端面の間の隙間に引き治具１６を挿入し、引き治具１６の先端で掴み突部１５を掴み、引き治具１６を引っ張って目地部材４を屋内側に引っ張って圧入する。これにより図２（ｂ）に示すように外側シール片５は外装材２の側端面に弾接され、内側シール片６は縦凹溝３で外装材２の側端部の裏面側に弾接される。
【００１７】
この場合も、外側シール片５が外装材２の側端面に弾接されると共に内側シール片６が外装材２の側端部の裏面に弾接されることにより二重にシールされてパネル本体１側に水が浸入するのが防止される。そして外側シール片５を越えて水が浸入しても目地部材４の縦片４ａや横片４ｂと外装材２の側端部との間の空間を通って下方に流れて外部に排水される。また縦凹溝３に金属の縦溝材７を設けてあることでもパネル本体１の方に水が浸入するのを一層防止できる。
【００１８】
また外壁パネルＡの下端には図３に示すように外装材２の下端部の裏面側に左右方向に亙るように下方を開口せる断面略コ字状の横凹溝８を凹設してある。この横凹溝８にも鋼板のような金属板にて形成せる断面略コ字状の溝型材１７を内面に沿わせて装着してある。上記縦凹溝３の下部と横凹溝８の左右の端部とは連通させてある。つまり、図４に示すように横凹溝８の溝型材１７の左右方向の端部に切り欠き１８を設けてあり、縦凹溝３の溝型材１７の端部を切り欠き１８に挿入して接続してある。横凹溝８の上底の裏側の隅部にはゴム、合成樹脂等の水密材１０を左右方向に亙って装着してある。外壁パネルＡのパネル本体１の下端面には横凹溝８より裏側で左右方向に亙って係止凹部２０を左右方向に亙って凹設してある。
【００１９】
外壁パネルＡは上記のように左右に並べて立設されるのであるが、上下方向にも並べて上下に接続されるものであり、上下に隣り合う外壁パネルＡは次のように接続される。下に位置する外壁パネルＡのパネル本体１には上方に突出するように係止金具２１を装着してある。また下に位置する外壁パネルＡの上端には係止金具２１より表面側の位置で止水部材９を装着してある。この止水部材９は縦片部９ａと横片部９ｂとで断面略Ｌ字状に形成されており、横片部９ｂを下に位置する外壁パネルＡに載せ、縦片部９ａの下端から横片部９ｂと反対方向に連出した固定片２２をビス等の固着具２７にて固着してある。
【００２０】
止水部材９の横片部９ｂの上には図５に示すように２条の係止凸条２３を平行に突設してある。この係止凸条２３は長手方向に連続していなく、間隙Ｓを隔ててある。水切り板２４は横片部２４ａと縦片部２４ｂとで断面略逆Ｌ字状に形成されており、横片部２４ａの下面側には２条の被係止凸条２５を平行に突設してある。この被係止凸条２５も長手方向に連続していなく、間隙Ｓを隔ててある。止水部材９の横片部９ｂの上には水切り板２４の横片部２４ａが重ねられ、係止凸条２３と被係止凸条２５が係止されて水切り板２４が取り付けられる。水切り板２４の横片部２４ａの上にはゴム、合成樹脂等の水密材２６が長手方向に亙って装着されている。
【００２１】
図３（ａ）（ｂ）のように下に位置する外壁パネルＡの上に外壁パネルＡを立設したとき下に位置する外壁パネルＡの係止金具２１の上端が上に位置する外壁パネルＡの係止凹部２０に係止される。またこの状態で上に位置する外壁パネルＡの外装材２の下端が水密材２６に圧接される。また下に位置する外壁パネルＡの止水部材９の縦片部９ａは上に位置する外壁パネルＡの横凹溝８内に挿入され、縦片部９ａの上端が水密材１０に圧接される。
【００２２】
上記のように施工されるが、目地部材４の縦片４ａや横片４ｂと外装材２の端部との間の空間を伝って流れ落ちてきた水が止水部材９の横片部９ｂに落ちて横片部９ｂから横片部９ｂと水切り板２４の横片部２４ａとの間の間隙Ｓを通って図５の符号Ｗに示すように排水される。このとき目地部材４の裏側に止水部材９の縦片部９ａが位置するためパネル本体１側に水が浸入するおそれがない。このとき縦片部９ａの上端が水密材１０に圧接されることによりパネル本体１側に水が浸入するのを一層確実に防止できる。
【００２３】
