Description

【０００１】
【発明の属する技術分野】
本発明は、建物の外壁を形成する外壁材を建物躯体に取付ける構造に関する。
【０００２】
【従来の技術】
横長の外壁材を建物躯体に取付ける構造としては、例えば特開平６−１３６９１１号公報に示すように、壁下地に縦長のジョイナを取付け、このジョイナに横長の外壁材の端部を下から上に重ね合せて順次固着し、そのジョイナに化粧カバーを取付けると共に、この化粧カバーと外壁材の室外面との間に湿式のシーリング材を充填してシールするものが知られている。
【０００３】
【発明が解決しようとする課題】
前述の取付構造であれば外壁材の室外面と化粧カバーとの間がシーリング材でシールされると共に、上下に隣接した外壁材の室外寄り対向面間がシーリング材でシールされるから、その外壁材の端部連結部と化粧カバーとの部分から雨水等が強風雨によって壁下地側に浸入することを防止できる。
【０００４】
しかしながら、前述の取付構造は施工現場で湿式のシーリング材を充填するので、熟練した作業者が必要であるし、シーリング材の充填に長時間かかり施工効率が悪い。
【０００５】
そこで、本発明は前述の課題を解決できるようにした外壁材の取付構造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】
本発明は、建物躯体に取付けたジョイナ２と、このジョイナ２に取付けた化粧カバー４との間に横長の外壁材３の端部を突出させて上下方向に重ね合せて複数取付け、
前記ジョイナ２に、各外壁材３の室内面とジョイナ２との間をシールする乾式の室内側の防水シール１４を取付け、前記化粧カバー４に、この化粧カバー４と各外壁材３の室外面との間をシールする乾式の室外側の防水シール４２を取付け、
前記外壁材３は、上部に室外寄り雄型連結部２０と中間上向き凹溝２１と室内寄り雄型連結部２２を有し、下部には室外寄り雌型連結部２３と室内寄り雌型連結部２４を有する形状で、下の外壁材３の室外寄り雄型連結部２０、室内寄り雄型連結部２２と上の外壁材３の室外寄り雌型連結部２３、室内寄り雌型連結部２４が嵌まり合って中間上向き凹溝２１部分に長手方向に連続した空洞部５１を形成し、
前記各外壁材３の端部に、前記室内側の防水シール１４と上下の外壁材３の室内寄り対向面に圧着すると共に、前記室外側の防水シール４２と上下の外壁材３の室外寄り対向面に圧着する乾式の端部シール３０を取付け、
前記端部シール材３０は、室外側シール部３１と室内側シール部３２と中間連結部３３で前記室外寄り雄型連結部２０と室内寄り雄型連結部２２に跨って嵌め込み装着されるほぼ下向きコ字形状で、その中間連結部３３は下向きの外力によって分離する形状であることを特徴とする外壁材の取付構造である。
【０００９】
【作用】
第１の発明によれば、上下の外壁材３の室外面と化粧カバー４の間が防水シール４２でシールされると共に、上下の外壁材３の室外寄り対向面間が端部シール材３０でシールされ、その端部シール材３０が防水シール４２に圧着していることによって、上下の外壁材３の端部連結部と化粧カバー４との間が確実にシールされて強風雨によって雨水等が建物躯体側に浸入することがない。
【００１０】
また、防水シール４２、端部シール材３０は乾式であるから、あらかじめ化粧カバー４、外壁材３の端部にそれぞれ装着し、施工現場ではジョイナ２、外壁材３、化粧カバー４を取付ければ良いので、熟練者でない通常の作業者が外壁材を短時間に容易に取付けでき、施工性が向上する。
【００１２】
また、上下の外壁材３の室内面とジョイナ２の間が室内側の防水シール１４でシールされると共に、上下の外壁材３の室内寄り対向面間が端部シール材３０でシールされ、その端部シール材３０が室内側の防水シール１４に圧着していることによって、上下の外壁材３の端部連結部とジョイナ２との間が確実にシールされて何らかの事情で化粧カバー４の室内側に入り込んだ雨水等が建物躯体側に浸入することがない。
【００１３】
また、室内側の防水シール１４、室外側の防水シール４２、端部シール材３０は乾式であるから、あらかじめジョイナ２、化粧カバー４、外壁材３の端部にそれぞれ装着し、施工現場ではジョイナ２、外壁材３、化粧カバー４を取付ければ良いので、熟練者でない通常の作業者が外壁材を短時間に容易に取付けでき、施工性が向上する。
【００１４】
また、端部シール材３０を外壁材３の上部に、外壁材３の運搬、取付時に外れないように簡単に装着できる。下の外壁材３に上の外壁材３を重ね合せることで端部シール材３０の中間連結部３３が分離して室外側シール部３１と室内側シール部３２が不連続となり、雨水等が端部シール材３０を伝わってジョイナ２まで浸入することがない。
【００１５】
また、上下の外壁材３の連結部より浸入した雨水等は空洞部５１に沿って外壁材３の端部から流れ落ち、その雨水等が建物躯体側に浸入しない。
【００１６】
【発明の実施の形態】
図１に示すように、建物躯体、例えば柱１の室外面に縦長のジョイナ２が取付けてある。横長の外壁材３は下から上に順次重ね合せて取付けられ、その外壁材３の室内面の端部がジョイナ２に接し、かつ柱１に固着される。前記ジョイナ２に化粧カバー４が取付けてあり、その化粧カバー４は左右の外壁材３の室外面の端部に接している。
【００１７】
前記ジョイナ２は図２，図３に示すように、所定の幅を有する長尺な基板１０と、この基板１０の幅方向中央部に長手方向に連続して一体的に設けた一対の突出片１１，１１を有し、その一対の突出片１１，１１の突出端部が係止受部１２となっている。基板１０の幅方向両端部が固着具１３で柱１の室外面１ａにそれぞれ固着され、基板１０の幅方向両端寄りに乾式の防水シール１４が接着剤等で貼着して取付けてある。
【００１８】
前記外壁材３は図４に示すように、上部に室外寄り雄型連結部２０、中間上向き凹溝２１、室内寄り雄型連結部２２を有し、下部に室外寄り雌型連結部２３、室内寄り雌型連結部２４を有している。この実施の形態では外壁材３はアルミ表面板２５とアルミ裏面板２６で中空形状で、その中空部に発泡ウレタンなどの断熱材２７が充填されたアルミ外壁材としてあるが、外壁材３はこのものに限ることはない。
【００１９】
前記外壁材３の室外寄り雌型連結部２３の底部に乾式の室外寄り横シール材２８が長手方向に連続して設けてあり、室内寄り雌型連結部２４の底部に乾式の室内寄り横シール材２９が長手方向に連続して設けてある。
【００２０】
前記外壁材３の上部における長手方向の両端部には乾式の端部シール材３０が装着してある。この端部シール材３０は室外側シール部３１と室内側シール部３２と薄板状の中間連結部３３でほぼ下向コ字状で、室外寄り雄型連結部２０と室内寄り雄型連結部２２に跨って嵌め込んで取付けられ、その中間連結部３３と中間上向き凹溝２１との間に空洞部を形成している。前記中間連結部３３にはスリット３４が形成されて下向きの外力が作用すると破断して室外側シール部３１と室内側シール部３２が分離する。なお、中間連結部３３を室外側部分と室内側部分に二分割し、テープ等で連結して下向きの外力が作用するとテープが剥離して室外側シール部３１と室内側シール部３２が分離するようにしても良い。
【００２１】
前記化粧カバー４は図２，図３に示すように、押え板４０に一対の係止片４１を室内側に向けて一体的に設けた形状で、その係止片４１を前記一対の突出片１１の係止受部１２にスナップ式に係合して取付けられる。前記押え板４０の室内面の幅方向両端寄りに乾式の防水シール４２が長手方向に連続して接着剤等で貼着して設けてある。
【００２２】
図５に示すように外壁材３の室内寄り雄型連結部２２から固着具、例えばドリルネジ５０をジョイナ２の基板１０を貫通して柱１にねじ込んで外壁材３を柱１に取付ける。
この取付けた外壁材３の上に次の外壁材３を重ね合せると、外壁材３の下部における中間部分が端部シール材３０の中間連結部３３を下方に押しつけ、その中間連結部３３が破断する。
【００２３】
下の外壁材３の室外寄り雄部連結部２０、室内寄り雄部連結部２２と上の外壁材３の室外寄り雌部連結部２３、室内寄り雌部連結部２４がそれぞれ嵌まり合って中間上向き凹溝２１部分に長手方向に連続した空洞部５１が形成される。上下の外壁材３の空洞部５１よりも室外側が室外寄り横シール材２８でシールされ、室内側が室内寄り横シール材２９でシールされる。つまり、上下の外壁材３の横目地部がシールされる。
【００２４】
これとともに端部シール材３０の室外側シール部３１が上下の外壁材３の室外側対向面と防水シール４２に圧着し、上下の外壁材３の端部連結部と化粧カバー４の押え板４０との間を確実にシールし、強風雨などによって雨水等が柱１側に浸入することがない。
【００２５】
また、端部シール材３０の室内側シール部３２が上下の外壁材３の室内側対向面と防水シール１４に圧着し、上下の外壁材３の端部連結部とジョイナ２の基板１０との間を確実にシールし、ジョイナ２と外壁材３端面との間に浸入した雨水等がジョイナ２を越えて建物躯体側に浸入することがない。
【００２６】
また、強風雨等によって上下の外壁材３の室外側の横目地部から雨水等が浸入することがあるが、この雨水等は空洞部５１に沿って長手方向に流れて外壁材３の端面とジョイナ２との間の縦空間に流れ落ち、室内側の横目地部を通って室内側に浸入することがない。
特に、図５に示すように室外側の横目地部（室外寄り横シール材２８）よりも室内側の横目地部（室内寄り横シール材２９）が上方位置であるから、空洞部５１の雨水等が室内側の横目地部を通って室内側に浸入することがない。
【００２７】
入隅部に外壁材を取付ける場合には図６に示すように、ジョイナ２の基板１０を中間部１０ａと一側取付部１０ｂと他側取付部１０ｃを有する形状とし、その一側取付部１０ｂ、他側取付部１０ｃをコーナーの柱１にそれぞれ取付けると共に、入隅部を形成する２つの外壁材３をそれぞれ取付ける。化粧カバー４の押え板４０は鉤形状として入隅部を形成する２つの外壁材３の室外面とそれぞれ対向させる。
【００２８】
出隅部に外壁材を取付ける場合には図７に示すように、ジョイナ２の基板１０と化粧カバー４の押え板４０を鉤形状とすれば良い。
【００２９】
【発明の効果】
請求項１に係る発明によれば、上下の外壁材３の室外面と化粧カバー４の間が防水シール４２でシールされると共に、上下の外壁材３の室外寄り対向面間が端部シール材３０でシールされ、その端部シール材３０が防水シール４２に圧着していることによって、上下の外壁材３の端部連結部と化粧カバー４との間が確実にシールされて強風雨によって雨水等が建物躯体側に浸入することがない。
【００３０】
また、防水シール４２、端部シール材３０は乾式であるから、あらかじめ化粧カバー４、外壁材３の端部にそれぞれ装着し、施工現場ではジョイナ２、外壁材３、化粧カバー４を取付ければ良いので、熟練者でない通常の作業者が外壁材を短時間に容易に取付けでき、施工性が向上する。
【００３２】
また、上下の外壁材３の室内面とジョイナ２の間が室内側の防水シール１４でシールされると共に、上下の外壁材３の室内寄り対向面間が端部シール材３０でシールされ、その端部シール材３０が室内側の防水シール１４に圧着していることによって、上下の外壁材３の端部連結部とジョイナ２との間が確実にシールされて何らかの事情で化粧カバー４の室内側に入り込んだ雨水等が建物躯体側に浸入することがない。
【００３３】
また、室内側の防水シール１４、室外側の防水シール４２、端部シール材３０は乾式であるから、あらかじめジョイナ２、化粧カバー４、外壁材３の端部にそれぞれ装着し、施工現場ではジョイナ２、外壁材３、化粧カバー４を取付ければ良いので、熟練者でない通常の作業者が外壁材を短時間に容易に取付けでき、施工性が向上する。
【００３４】
また、端部シール材３０を外壁材３の上部に、外壁材３の運搬、取付時に外れないように簡単に装着できる。下の外壁材３に上の外壁材３を重ね合せることで端部シール材３０の中間連結部３３が分離して室外側シール部３１と室内側シール部３２が不連続となり、雨水等が端部シール材３０を伝わってジョイナ２まで浸入することがない。
【００３５】
また、上下の外壁材３の連結部より浸入し雨水等は空洞部５１に沿って外壁材３の端部から流れ落ち、その雨水等が建物躯体側に浸入しない。
