Description

【０００１】
【発明の属する技術分野】
本発明は、壁パネルの水切り構造に関するものである。
【０００２】
【従来の技術】
従来、枠材の表面に面材が取着されたパネル本体の表面全体に防水シートを貼り、防水シートの表面側に胴縁を介して外装材を取り付けて構成された壁パネルにおいて、ユニットパネル工法の土台部と壁パネルとのジョイント部、或いは上階の壁パネルと下階の壁パネルとのジョイント部の水切りを行うに当たっては、図１０に示すように、パネル本体２の下端部に断面略Ｌ字状の水切り部材１２´の上部を取り付け、水切り部材１２´の下部を外装材７の前面よりも外方Ａに且つ壁パネル１´の下端部１ａよりも下方に突出させるようにしている。
【０００３】
【発明が解決しようとする課題】
ところが、従来のように、水切り部材１２´を工場で取り付けてしまうと、水切り部材１２´の下部が壁パネル１´の下端部１ａよりも下方に突出しているために、運搬・建込み時に水切り部材１２´が物に当たって曲がったり、潰されたりするおそれがあり、運搬や建て込みがしにくいという問題がある。
【０００４】
一方、現場で施工された壁パネル１´に水切り部材１２´を後から取り付ける場合、水切り部材１２´の上部を防水シート５の裏面に差込んで、この水切り部材１２´の上部をビス２０でパネル本体２に取り付ける必要がある。このとき、水切り部材１２´を誤って防水シート５の表面側から取り付けてしまったり、或いは水切り部材１２´によって防水シート５がめくり上がり、この状態で水切り部材１２´を取り付けてしまったりする可能性があり、この場合、壁パネル１´の防水性能が損なわれるという問題が生じる。
【０００５】
そこで、従来では、外装材７をパネル本体２に取り付けないで現場に搬入し、現場で水切り部材１２´をパネル本体２に取り付け、その後、外装材７を取り付けるようにしていた。このため、現場での施工に多大な手間と時間がかかるという問題があった。
【０００６】
本発明は上記の点に鑑みてなされたものであり、その目的とするところは、
運搬・建込み時における水切り部材の破損、変形などの弊害をなくすことができ、しかも、現場での水切り部材の取り付けを容易に且つ確実に行うことができ、現場作業を簡略化しながら、防水性能の向上を図ることができるようにした壁パネルの水切り構造を提供するにあり、別の目的とするところは、現場で下側水切り片を後付けする際に下側水切り片を正規の取り付け位置に簡易に取り付けることができる壁パネルの水切り構造を提供するにある。
【０００７】
【課題を解決するための手段】
上記課題を解決するために、本発明は、枠材３の表面に面材４が取着されたパネル本体２の表面全体に防水シート５を貼り、防水シート５の表面側に胴縁６を介して外装材７を取り付けて壁パネル１が構成され、パネル本体２の下端部に外装材７の前面よりも外方Ａに且つ壁パネル１の下端部１ａより下方に突出するように突出するように水切り部材１２が取り付けられ、水切り部材１２により上階の壁パネル１と下階の壁パネル１とのジョイント部８或いは壁パネル１と土台部９とのジョイント部１０を覆うようにしてなる壁パネル１の水切り構造において、水切り部材１２が、壁パネル１の下端部１ａよりも下方に突出しない上側水切り片１３と、壁パネル１の下端部１ａよりも下方に突出する断面略Ｌ字状の下側水切り片１４とに上下に２分割され、上側水切り片１３の上部を防水シート５の裏面側に配置して固着具によりパネル本体２に取り付けると共に、下側水切り片１４の上部をパネル本体２又は上側水切り片１３のいずれかに取り付けて成ることを特徴としており、このように構成することで、工場で上側水切り片１３を先付けしても、上側水切り片１３は壁パネル１の下端部１ａから下方に突出しないので、壁パネル１の運搬・建込み時に、上側水切り片１３が変形したり、潰されたりする恐れがなくなる。また、現場で下側水切り片１４を後付けするときに、上側水切り片１３の上部は防水シート５の裏面側に差込まれているので、下側水切り片１４の上部を上側水切り片１３又はパネル本体２に取付ける際に、防水シート５が下側水切り片１４によってめくれ上がったりすることがなく、さらに、下側水切り片１４を誤って防水シート５の表面側に取り付けてしまったりする可能性もないので、下側水切り片１４の取り付けをミスなく確実に行うことができる。
【０００８】
また、上記下側水切り片１４の上部を上側水切り片１３の裏面側に差込んで別の固着具によりパネル本体２に取り付けるのが好ましく、この場合、下側水切り片１４の上部が上側水切り片１３とパネル本体２との間に挟まれた形となり、下側水切り片１４のパネル本体２への取り付けが容易になると共に、また、下側水切り片１４の上に上側水切り片１３が積層され、さらにその上に防水シート５が積層された構造となるので、壁パネル１の防水性能を十分に高めることができる。
【０００９】
また、上記上側水切り片１３に係合部２２を設け、下側水切り片１４に該係合部２２に対して係合可能な被係合部２３を設けるのが好ましく、この場合、現場で、下側水切り片１４の被係合部２３を上側水切り片１３の係合部２２に係合させるだけで、下側水切り片１４を上側水切り片１３に対して仮固定でき、下側水切り片１４を上側水切り片１３に対して手で抑える必要がないので、一人でも下側水切り片１４の取り付け作業を簡単に行うことができる。
【００１０】
また、上記上側水切り片１３に位置決め用段部２４を設け、下側水切り片１４を該位置決め用段部２４で位置決めした状態で、上側水切り片１３を別の固着具によりパネル本体２に取り付けるのが好ましく、この場合、位置決め用段部２４により下側水切り片１４を正規の位置に容易に配置できるので、現場で下側水切り片１４を取り付ける際に、下側水切り片１４の取り付け位置にばらつきが生じるという不具合を回避できる。
【００１１】
【発明の実施の形態】
以下、本発明の実施の形態を説明する。
【００１２】
本実施形態の壁パネル１は、図１に示すように、枠材３の表面に面材４が取着されたパネル本体２の表面全体に透湿防水シート５を貼り、透湿防水シート５の表面側に横胴縁６を介して外装材７を取り付けて構成されている。図２は、水切り部材１２をユニットパネル工法の１階の壁パネル１と土台部９との間の土台側ジョイント部８に配置した場合を示している。図１中の３０はモルタル部である。
【００１３】
パネル本体２を構成する枠材３は例えば軽量鉄骨或いは木材をロ字状に枠組みしたものが用いられ、面材４としては例えばパーティクルボード等が用いられる。もちろん、枠材３及び面材４の材質はこれに限定されるものではない。また、透湿防水シート５は、例えば２層構造をしており、裏層の透湿防水シート５Ｂの下端部はパネル本体２の下端部まで達しており、表層の透湿防水シート５Ａの下端部は裏層の透湿防水シート５Ｂよりも短く形成されており、透湿防水シート５Ａ，５Ｂの間に、水切り部材１２の上部が挿入されて、ビス２０，２１によりパネル本体２に取り付けられるようになっている。
【００１４】
水切り部材１２は、外装材７の表面７ｂよりも外方Ａに且つ壁パネル１の下端部１ａより下方に突出するように取り付けられる。
【００１５】
水切り部材１２は、例えばアルミニウム或いは鋼鈑などで構成されており、壁パネル１の下端部１ａよりも下方に突出しない上側水切り片１３と、壁パネル１の下端部１ａよりも下方に突出する断面略Ｌ字状の下側水切り片１４とに上下に２分割されている。
【００１６】
上側水切り片１３及び下側水切り片１４は、パネル本体２の横幅方向の全長に亘る長さを有している。上側水切り片１３は、図３（ａ）に示すように、パネル本体２にビス止めされる固定部１５と、固定部１５の下端から斜め前下方に延出された傾斜部１６とで構成されている。固定部１５の上端及び傾斜部１６の下端にはそれぞれ略Ｕ字状の水返し部３１，３２が一体に形成されている。
【００１７】
ここで、固定部１５と傾斜部１６との傾斜角度φは例えば１６０°に設定され、上側水切り片１３全体の厚みＬ_１は図２に示す横胴縁６の厚みｄよりも薄く設定され、上側水切り片１３全体の縦幅Ｌ_２は最下段の横胴縁６と外装材７の下端部との間の距離Ｄよりも小さく設定されている。これにより、上側水切り片１３の上部を２層の透湿防水シート５Ａ，５Ｂの間に挿入し、固定部１５をビス２０によりパネル本体２に取り付けた状態で、上側水切り片１３全体が壁パネル１の下端部１ａよりも下方に突出しないように、つまり壁パネル１の下端部１ａよりも内側に引き込んだ位置に納まるようになり、壁パネル１の運搬・建込み時において、上側水切り片１３が曲がったり、潰されたりするのを防止できるようになっている。
【００１８】
一方、下側水切り片１４は、図３（ｂ）に示すように、パネル本体２にビス止めされる固定部１７と、固定部１７の下端から斜め前下方に延出された傾斜部１８と、傾斜部１８の下端から下方に延出された垂下部１９とで断面略階段状に形成されている。固定部１７の上端及び垂下部１９の下端にはそれぞれ略Ｕ字状の水返し部３３，３４が一体に形成されている。
【００１９】
ここで、傾斜部１８の傾斜方向に沿う長さＬ_３は、外装材７の表面７ｂからパネル本体２の表面に到る長さＤ_１よりも長く設定され、垂下部１９の垂下幅Ｌ_４は垂下部１９の下端が土台側ジョイント部８よりも下方に位置するように設定されており、これにより、下側水切り片１４の上部をパネル本体２に取り付けた状態で、下側水切り片１４の傾斜部１８の前端部分及び垂下部１９が外装材７の前面よりも外方Ａに且つ壁パネル１の下端部１ａよりも下方に突出するようになり、透湿防水シート５Ａ上の水を上側水切り片１３から下側水切り片１４を伝って壁パネル１の外側に排水できるようになっている。
【００２０】
しかして、工場では、図２のように、パネル本体２の表面に２層の透湿防水シート５Ａ，５Ｂを貼り、透湿防水シート５Ａ，５Ｂ間に下方から上側水切り片１３の上部を差込んで、上側水切り片１３の上部をパネル本体２にビス２０で固着する。さらに、透湿防水シート５Ａの表面上に複数の横胴縁６を介してサイディング材などの外装材７を釘３５で固着して壁パネル１を完成させる。この状態では、上側水切り片１３は壁パネル１の下端部１ａから下方に突出しないように取り付けられているので、壁パネル１を運搬したり、建込んだりする時に、上側水切り片１３が曲がったり、潰されたりする恐れがなく、運搬及び建込み作業が容易となる。
【００２１】
次に、現場で壁パネル１を建込んだ後に、図１のように、先付けされた上側水切り片１３の傾斜部１６の背後に下側水切り片１４の上部を差込んで、下側水切り片１４の固定部１７をビス２１によりパネル本体２に固着する。これにより、下側水切り片１４を現場で後から簡単に取り付けることができ、そのうえ外装材７は工場で先に取り付けられているので、現場での外装材７の施工を省略できる。なお、外装材７は現場で取り付けるようにしてもよいが、省施工化を図るうえで、工場で先に取り付けておくのが望ましい。またこのような外装材７の先付けは、本発明の水切り部材１２を用いることによって可能になったものである。
【００２２】
また、先付けされた上側水切り片１３の上部は透湿防水シート５Ａの裏面側に差込まれているので、下側水切り片１４を後付けする際に、透湿防水シート５Ａが下側水切り片１４によってめくれ上がったり、或いは下側水切り片１４を誤って透湿防水シート５Ａの表面側に取り付けてしまったりする可能性がないので、下側水切り片１４の取り付けのミスを防ぐことができる。従って、雨水が浸入しても、透湿防水シート５Ａ及び水切り部材１２で水切りされて、屋外に排水される。しかも、裏層の透湿防水シート５Ｂの上に下側水切り片１４が積層され、その上に上側水切り片１３が積層され、さらにその上に表層の透湿防水シート５Ａが積層された形となっているので、壁パネル１の防水性能が十分に高められる。
【００２３】
本発明の水切り部材１２は、図１のように、ユニットパネル工法の壁パネル１と基礎部９との土台側ジョイント部１０を覆う場合に限らず、図４のように上階の壁パネル１と下階の壁パネル１との中間側ジョイント部８を覆う場合も同様に使用できるものである。つまり、１階の壁パネル１、２階の壁パネル１を建込んだ後、図４のイ部において２階の壁パネル１に先付けされている上側水切り片１３の裏面側に下側水切り片１４の上部を差込んでビス２１でパネル本体２に固定するだけでよい。
【００２４】
図５〜図７は他の実施形態を示している。この実施形態では、略Ｌ字状の上側水切り片１３の固定部１７に係合部２２を設け、略Ｌ字状の下側水切り片１４に該係合部２２に対して係合可能な被係合部２３を設けたものである。他の構成は図１、図２の実施形態と同様である。工場で先付けされる上側水切り片１３は、図６、図７（ａ）に示すように、パネル本体２にビス止めされる固定部１５と、固定部１５の下端から斜め前下方に延出された傾斜部１６とで構成されている。固定部１５の上半部は断面略逆Ｌ字状に形成され、固定部１５の下半部は断面Ｌ字状の係合部２２が形成され、係合部２２の上端には下方に開口した隙間４０が形成されている。一方、現場で後付けされる下側水切り片１４は、上側水切り片１３の係合部２２に係合される被係合部２３を備えた固定部１７と、被係合部２３の下端から斜め前下方に延出された傾斜部１８と、傾斜部１８の下端から下方に延出された垂下部１９とで断面略階段状に形成されている。しかして、下側水切り片１４の被係合部２３を上側水切り片１３の係合部２２の隙間４０に差し込み、その後、下側水切り片１４の傾斜部１８を上側水切り片１３の傾斜部１６に沿わせることによって、下側水切り片１４を上側水切り片１３に対して簡単に仮固定でき、この仮固定状態で、ビス２１を被係合部２３から係合部２２を貫通してパネル本体２に打ち込むことによって、下側水切り片１４を本固定できるようになる。このように下側水切り片１４を仮固定することで、下側水切り片１４を上側水切り片１３に対して手で抑える必要がないので、一人でも下側水切り片１４の取り付け作業を楽に行うことができる。しかも、下側水切り片１４は上側水切り片１３に下方から支えられた状態でパネル本体２に取り付けられるので、下側水切り片１４の取り付け強度を向上させることができ、施工の信頼性も同時に向上させることができる。
【００２５】
また、図５〜図７の変形例として、図８に示すように、上側水切り片１３の係合部２２の上下両側に隙間４０，４１をそれぞれ設けると共に、下側水切り片１４に被係合部４２，４３をそれぞれ設けるようにしてもよく、これにより下側水切り片１４の被係合部４２，４３を、横方向から上側水切り片１３の隙間４０，４１に差込むだけで、下側水切り片１４を上側水切り片１３に対して固定でき、ビスなしで下側水切り片１４の固定ができるようになる。また、下側水切り片１４をパネル本体２に固定する必要がないので、作業が一層はかどる。もちろん、ビスで下側水切り片１４の固定部１７を図７のようにパネル本体２に固着してもよいものである。
【００２６】
図９は更に他の実施形態を示しており、上側水切り片１３に位置決め用段部２４を設け、下側水切り片１４を該位置決め用段部２４で位置決めした状態で、上側水切り片１３をビス２０などの固着具によりパネル本体２に取り付けるようにしたものである。他の構成は図１、図２の実施形態と同様である。この実施形態では、位置決め用段部２４は下側水切り片１４の上端部１７ａに接触する部分に形成され、位置決め用段部２４の下面に下側水切り片１４の固定部１７の上端部が当接したときに、下側水切り片１４が正規の位置にくるように設計されている。これにより、現場で下側水切り片１４を取り付ける際に、下側水切り片１４の取り付け位置にばらつきが生じるという不具合を回避でき、施工の信頼性が一層向上するものである。
【００２７】
【発明の効果】
以上説明したように、本発明のうち請求項１記載の発明は、枠材の表面に面材が取着されたパネル本体の表面全体に防水シートを貼り、防水シートの表面側に胴縁を介して外装材を取り付けて壁パネルが構成され、パネル本体の下端部に外装材の前面よりも外方に且つ壁パネルの下端部より下方に突出するように水切り部材が取り付けられ、水切り部材により上階の壁パネルと下階の壁パネルとのジョイント部或いは壁パネルと土台部とのジョイント部を覆うようにしてなる壁パネルの水切り構造において、水切り部材が、壁パネルの下端部よりも下方に突出しない上側水切り片と、壁パネルの下端部よりも下方に突出する断面略Ｌ字状の下側水切り片とに上下に２分割され、上側水切り片の上部を防水シートの裏面側に配置して固着具によりパネル本体に取り付けると共に、下側水切り片の上部をパネル本体又は上側水切り片のいずれかに取り付けて成るから、工場で上側水切り片を先付けした場合でも、上側水切り片は壁パネルの下端部から下方に突出しないので、壁パネルの運搬・建込み時に、上側水切り片が変形したり、潰されたりする恐れがなくなる。また、現場で下側水切り片を後付けするときに、上側水切り片の上部は防水シートの裏面側に差込まれているので、下側水切り片の上部を上側水切り片又はパネル本体に取付ける際に、防水シートが下側水切り片によってめくれ上がったりすることがなく、さらに、下側水切り片を誤って防水シートの表面側に取り付けてしまったりする可能性もないので、下側水切り片の取り付けをミスなく確実に行うことができ、現場の作業がはかどる。
【００２８】
また請求項２記載の発明は、上記水切り部材が、壁パネルの下端部よりも下方に突出しない上側水切り片と、壁パネルの下端部よりも下方に突出する断面略Ｌ字状の下側水切り片とに上下に２分割され、上側水切り片の上部を防水シートの裏面側に配置して固着具によりパネル本体に取り付けると共に、下側水切り片の上部を上側水切り片の裏面側に差込んで別の固着具によりパネル本体に取り付けて成るから、下側水切り片の上部が上側水切り片とパネル本体との間に挟まれた形となり、下側水切り片のパネル本体への取り付けが容易になると共に、下側水切り片の上に上側水切り片が積層され、さらにその上に防水シートが積層された構造となるので、壁パネルの防水性能を十分に高めることができる。
【００２９】
また請求項３記載の発明は、上記水切り部材が、壁パネルの下端部よりも下方に突出しない上側水切り片と、壁パネルの下端部よりも下方に突出する断面略Ｌ字状の下側水切り片とに上下に２分割され、上側水切り片の上部を防水シートの裏面側に配置して固着具によりパネル本体に取り付けると共に、上側水切り片に係合部を設け、下側水切り片に該係合部に対して係合可能な被係合部を設けたから、現場において、下側水切り片の被係合部を上側水切り片の係合部に係合させることによって、下側水切り片を上側水切り片に対して仮固定でき、この仮固定状態で、ビスなどの固着具で下側水切り片を固定することにより、下側水切り片の固着作業が容易となり、現場作業がはかどると共に、下側水切り片を上側水切り片に対して手で抑える必要がないので、一人でも下側水切り片の取り付け作業を簡単に行うことができる。また、上側水切り片と下側水切り片に設けた係合部と被係合部とを係合させるので、部品数が増えるのを防止でき、さらに、下側水切り片は上側水切り片に係合状態で固定されるので、外装材の外方に突出する下側水切り片の取り付け強度を向上させることができ、施工の信頼性も同時に向上させることができるものである。
【００３０】
また請求項４記載の発明は、上記水切り部材が、壁パネルの下端部よりも下方に突出しない上側水切り片と、壁パネルの下端部よりも下方に突出する断面略Ｌ字状の下側水切り片とに上下に２分割され、上側水切り片の上部を防水シートの裏面側に配置して固着具によりパネル本体に取り付けると共に、上側水切り片に位置決め用段部を設け、下側水切り片を該位置決め用段部で位置決めした状態で、上側水切り片を別の固着具によりパネル本体に取り付けて成るから、位置決め用段部により下側水切り片を正規の位置に容易に配置できるので、現場で下側水切り片を取り付ける際に、下側水切り片の取り付け位置にばらつきが生じるという不具合を回避できる。
