【０００１】
【発明の属する技術分野】
本発明は、建物の外壁に取付けられる水切りの取付構造、および水切りの施工方法に係わり、特に壁パネルの表面に外装材が取付けられた外装材付き壁パネル間に取付けられる水切りの取付構造、および水切りの施工方法に関する。
【０００２】
【背景の技術】
近年、住宅の構築についてはその工業化が進み、例えば壁や床、屋根といった構成要素を予め工場にてパネル化しておき、施工現場でこれらのパネルを組み立てることにより、住宅を構築するといったパネル工法が一部に採用されている。このようなパネル工法に用いられるパネルとして、例えば、図８に示すような壁パネル１００が知られている。
【０００３】
図８に示す壁パネル１００は、縦框材１００ａ、１００ａと横框材１００ｂ、１００ｂとが矩形状に組み立てられるとともに、この矩形枠の内部に補強桟材１０２が縦横に組まれて枠体１０３が形成され、さらにこの枠体１０３内にグラスウールなどの断熱材（図示しない）が充填された状態で枠体１０３の表裏面に合板などの面材１０４、１０４が貼設されたものである。そして、外壁パネルでは、更に現場での施工を簡略にするため、前記面材１０４に胴縁を取り付け、その上に外装材を貼設する、いわゆる艤装を行っているものがある。
【０００４】
この場合、例えば、特開２００１−１５２５６６号公報に開示された技術が知られている。この技術は、建物の外壁となる複数の壁パネルと、この壁パネルの外面側を覆うように設けられる防水シートと、この防水シート上から壁パネルに取付けられる外装材とから外装材付き壁パネルが形成され、この外装材付き壁パネルが建築現場に搬送されるともに設置されてなるものである。そして、前記公報の外装材付き壁パネルを適用した外壁は、上階の外壁を構成する外装材付き壁パネルの外装材の表面下端部と、下階の外壁を構成すある外装材付き壁パネルの外装材の表面上端部との間に現場で幕板を取付けることによって、上階の外装材の下端部と下階の外装材の上端部との間から、上階の外装材および下階の外装材の裏面側に雨水などの水が侵入するのを防止している。
【０００５】
【発明が解決しようとする課題】
ところで、前記公報の記載の技術では、上側の外装材付き壁パネルの下端部と、下側の外装材付き壁パネルの外装材の上端部との間隔が比較的大きく、この隙間を覆うため幕板を使用している。この幕板は外装材と同質材や塩ビ鋼板等で形成されており、しかも比較的大きい隙間を覆うものなので、重量が嵩む。また、この幕板は、断面が大きいため、製作コストがかかっていた。このため、該幕板を上下の外装材付き壁パネル間に取付ける場合、取付作業に手間がかかり、さらには、該幕板を現場に出荷するための輸送コストもかかっていた。
【０００６】
本発明の課題は、上下に配置された外装材付き壁パネル間に、幕板の代わりに水切りを容易に取付けることができる水切りの取付構造、および水切りの施工方法を提供することである。
【０００７】
【課題を解決するための手段】
以上の課題を解決するため、請求項１記載の発明は、例えば図１〜図３、および図６に示すように、壁パネル１００、１００の表面２に外装材３、１１が取付けられた外装材付き壁パネル４、１０が上下に配置され、これら外装材付き壁パネル４、１０間１５に水切り６を取付ける水切り６の取付構造であって、
前記水切り６は、取付部７と、この取付部７の下端に形成された水切り部８とを備え、
前記上側（２階）の外装材付き壁パネル４を構成する壁パネル１００の下端部４ａには、該壁パネル１００の下端４ｂより下方に突出する下耳部５が取付けられており、この下耳部５に前記外装材３の下端部３ｂが位置しており、
前記下側（１階）の外装材付き壁パネル１０の外装材１１の上端１１ａが、前記上側の外装材付き壁パネル４の外装材３の下端３ａに近接しており、
前記水切り６の取付部７は、前記上側の外装材付き壁パネル４の外装材３と、下側の外装材付き壁パネル１０の外装材１１との間１５から挿入されて前記下耳部５に取り付けられており、
前記水切り６の水切り部８は、下側の外装材付き壁パネル１０の外装材１１の表面上端部１１ｂおよび上端１１ａ面を覆っていることを特徴とする。
ここで、前記水切り６は、塩ビ鋼板やアルミ等で形成されている。
【０００８】
請求項１記載の発明によれば、下側の外装材１１の上端１１ａが、上側の外装材３の下端３ａに近接しているので、前記間１５の間隔を狭くすることができる。また、水切り６の取付部８が前記間１５から挿入されて、下耳部５に取付けられ、水切り６の水切り部８が、下側の外装材１１の表面上端部１１ｂおよび上端１１ａ面を覆っているので、雨水などの水の侵入を防止できる水切り６を容易に取付けることができる。よって、前記公報の技術のように、前記間１５を覆う幕板を取付ける必要がないので、幕板の取り付け作業に係わる施工コスト、および幕板を現場に出荷するための輸送コストの低廉化が図れる。
【０００９】
請求項２記載の発明は、例えば図１〜図３、および図６に示すように、請求項１記載の水切り６の取付構造において、
前記下側の外装材付き壁パネル１０の上端面１０ａに、床パネル１２の端部１２ａが支持されており、この床パネル１２の端部上面１２ｂに前記上側の外装材付き壁パネル４が支持されており、
前記下耳部５は、前記床パネル１２の端部下面１２ｃまで延出されており、該下耳部５に位置する外装材３の下端３ａは、下耳部５の下端５ａより若干上方に位置していることを特徴とする。
【００１０】
請求項２記載の発明によれば、上側の外装材付き壁パネル４の下端部４ａに取付けられた下耳部５が床パネル１２の端部下面１２ｃまで延出されており、該下耳部５に位置する外装材３の下端３ａが下耳部５の下端５ａより若干上方に位置しているので、下側の外装材１１の上端１１ａと、上側の外装材３の下端３ａとを近接させることができる。よって、上下の外装材３、１１を上下の壁パネル１００、１００に対して、連続的に取付けることができる。また、下耳部５が、床パネル１２の端部下面１２ｃまで延出されているので、床パネル１２の端部１２ａを覆うことができる。そして、下耳部５に位置する外装材３の下端３ａが、下耳部５の下端５ａより若干上方に位置しているので、上側の外装材付き壁パネル４を出荷する際や吊り込んで施工する際に、外装材３の下端部３ｂを保護することができる。
【００１１】
請求項３記載の発明は、例えば図１、図４〜図６に示すように、請求項１記載の水切り６０の取付構造において、
前記下側（２階）の外装材付き壁パネル２０の上端面２０ａに、前記上側の外装材付き壁パネル（外装材付き小屋パネル）３０が直接支持されており、
前記下耳部２５は、前記下側の外装材付き壁パネル２０の壁パネル１００の表面上端部２０ｂに当接されたうえで固定され、
前記下耳部２５に位置する外装材３１の下端３１ａは、下耳部２５の下端２５ａより若干上方に位置していることを特徴とする。
【００１２】
請求項３記載の発明によれば、下側の外装材付き壁パネル２０の上端面２０ａに、上側の外装材付き壁パネル３０が直接支持され、下耳部２５が前記下側の外装材付き壁パネル２０の壁パネル１００の表面上端部２０ｂに当接した上で固定されているので、下側の外装材２１の上端２１ａと、上側の外装材３１の下端３１ａとを近接させることができるとともに、下側の外装材付き壁パネル２０の厚さ方向に対して、上側の外装材付き壁パネル３０の位置合わせが容易になる。よって、請求項２と同様に、上下の外装材２１、３１を上下の壁パネル１００、１００に対して、連続的に取付けることができる。
【００１３】
請求項４記載の発明は、例えば図７に示すように、請求項１〜３のいずれかに記載の水切り１６０の取付構造において、
前記水切り１６０の取付部７の表面７ｄには、この取付部７より上方に突出する軟質な止水部材１７０が、この止水部材１７０と取付部７との間に介在された両面防水テープ１７５によって取付けられていることを特徴とする。
ここで、前記両面防水テープ１７５は、ブチルゴム系またはゴムアス系で形成されている。また、前記止水部材１７０は、軟質塩ビで形成されている。
【００１４】
請求項４記載の発明によれば、水切り１６０の取付け部７の表面７ｄに、この取付部７より上方に突出する軟質な止水部材１７０が取付けられているので、水切り部８からの立ち上がりを高くすることができ、雨水等の水の侵入を効果的に防止できる。また、止水部材１７０が軟質であるので、前記間１５が狭くても、止水部材１７０を容易に外装材３の裏面３ｄ側に挿入できる。さらに、止水部材１７０が両面防水テープ１７５によって取付部７に取付けられているので、止水部材１７０と取付部７とを水密に接着できるとともに、取付部７をビスなどの止着材Ｂによって下耳部５に固定する際の止着材挿通穴（図示しない）からの水の侵入を前記両面防水テープ１７５によって防止できる。
【００１５】
請求項５記載の発明は、例えば図２〜図５および図７に示すように、請求項１〜４のいずれかに記載の水切り６の取付構造において、
前記下耳部５と外装材３との間には、水抜きパッキン材５０が介在されていることを特徴とする。
【００１６】
請求項５記載の発明によれば、水抜きパッキン５０によって、外装材３の裏面３ｂ側の水を容易に抜くことができる。
【００１７】
請求項６記載の発明は、例えば図１〜図３、および図６に示すように、請求項２記載の水切り６の取付構造を施工する水切り６の施工方法において、
前記下側の外装材付き壁パネル１０の上端面１０ａに、床パネル１２の端部１２ａを支持させた後、この床パネル１２の端部上面１２ｂに前記上側の外装材付き壁パネル４を支持させることにより、前記下側の外装材付き壁パネル１０の外装材１１の上端１１ａと、前記上側の外装材付き壁パネル４の外装材３の下端３ａとを近接させ、
次に、前記水切り６の取付部８を、前記上側の外装材付き壁パネル４の外装材３と、下側の外装材付き壁パネル１０の外装材１１との間１５から挿入して、前記下耳部５に取付るとともに、前記水切り６の水切り部８によって、下側の外装材付き壁パネル１０の外装材１１の表面上端部１１ｂおよび上端１１ａ面を覆うことを特徴とする。
【００１８】
請求項６記載の発明によれば、下側の外装材付き壁パネル１０の上端面１０ａに、床パネル１２の端部１２ａを支持させた後、この床パネル１２の端部上面１２ｂに上側の外装材付き壁パネル４を支持させることにより、下側の外装材１１の上端１１ａと、上側の外装材３の下端３ａとを近接させることができる。よって、前記間１５の間隔を狭くすることができるので、上下の外装材３、１１を上下の壁パネル１００、１００に対して、連続的に取付けることができる。次に、取付部８を、前記間１５から挿入して、下耳部５に取付るとともに、水切り部８によって、下側の外装材１１の表面上端部１１ｂおよび上端１１ａ面を覆うことにより、雨水などの水の侵入を防止することができる水切り６を容易に取付けることができる。よって、前記公報の技術のように、前記間１５を覆う幕板を取付ける必要がなくなり、幕板の取り付け作業に係わる施工コスト、および幕板を現場に出荷するための輸送コストの低廉化が図れる。
【００１９】
請求項７記載の発明は、例えば図１、図４〜図６に示すように、請求項３記載の水切り６０の取付構造を施工する水切り６０の施工方法において、
前記下側の外装材付き壁パネル２０の上端面２０ａに、前記上側の外装材付き壁パネル３０を直接支持させるとともに、前記下耳部２５を前記下側の外装材付き壁パネル２０の壁パネル１００の表面上端部２０ｂに当接した上で固定することにより、前記下側の外装材付き壁パネル２０の外装材２１の上端２１ａと、前記上側の外装材付き壁パネル３０の外装材３１の下端３１ａとを近接させ、
次に、前記水切り６０の取付部７０を、前記上側の外装材付き壁パネル３０の外装材３１と、下側の外装材付き壁パネル２０の外装材２１との間４５から挿入して、前記下耳部２５に取付けるとともに、前記水切り６０の水切り部８０によって、下側の外装材付き壁パネル２０の外装材２１の表面上端部２１ｂおよび上端２１ａ面を覆うことを特徴とする。
【００２０】
請求項７記載の発明によれば、下側の外装材付き壁パネル２０の上端面２０ａに、上側の外装材付き壁パネル３０を直接支持させるとともに、下耳部２５を下側の外装材付き壁パネル２０の壁パネル１００の表面上端部２０ｂに当接した上で固定することにより、下側の外装材２１の上端２１ａと、上側の外装材３１の下端３１ａとを近接させることができるとともに、下側の外装材付き壁パネル２０の厚さ方向に対して、上側の外装材付き壁パネル３０の位置合わせが容易になる。よって、請求項５と同様に、上下の外装材２１、３１を上下の壁パネル１００、１００に対して、連続的に取付けることができる。次に、取付部７０を、前記間４５から挿入して、下耳部２５に取付けるとともに、水切り部８０によって、下側の外装材２１の表面上端部２１ｂおよび上端２１ａ面を覆うことにより、雨水などの水の侵入を防止することができる水切り６０を容易に取付けることができる。よって、請求項５と同様に、幕板の取り付け作業に係わる施工コスト、および幕板を現場に出荷するための輸送コストの低廉化が図れる。
【００２１】
【発明の実施の形態】
以下、図１〜図８を参照して本発明の実施の形態を詳細に説明する。なお、本実施の形態の水切り材６の取付構造は、予め工場で製造された木質パネルを現場で組み付けることにより、床、壁、屋根などを構築するパネル工法を用いて構築された住宅に適用したものとして説明する。
【００２２】
（第１の実施の形態）
第１の実施の形態の水切りの取付構造は、図１（ａ）〜図３に示すように、壁パネル１００、１００の表面２に外装材３、１１が取付けられた外装材付き壁パネル４、１０が１階および２階の外壁として配置され、これら外装材付き壁パネル４、１０間１５に水切り６を取付けるものである。
【００２３】
２階（上側）の外装材付壁パネルは、壁体となる複数の壁パネル１００と、この壁パネル１００の外側の面材１０４に貼設された防水シート１０５と、この防水シート１０５上に取付けられた胴縁（図示しない）と、この胴縁に取付けられた外装材３と、壁パネル１００の外側の面材１０４の下端部４ａに取付けられ、該壁パネル１００の下端４ｂより下方に突出する下耳部５などにより概略構成され、予め工場で艤装されて製造される。
【００２４】
防水シート１０５は、壁パネル１００の外形と略同一寸法の矩形状のもので、壁パネル１００に接着剤等によって貼設されている。防水シート１０５の下端部は、下耳部５の下端５ａよりも延出して設けられている。防水シート１０５は、水を透過せず水蒸気は透過するミクロなポアを有するシートからなるもので、具体的には、タイペック（商品名：デュポン社製）等からなるものである。なお、図面上、防水シート１０５は破線で示し、胴縁、或いは水抜きパッキン５０に挟まれる部分については、見やすくするため胴縁、或いは水抜きパッキン５０の内側に表示した。
【００２５】
胴縁は、横方向に伸び、縦方向に所定の間隔で設けられており、例えば、木製の角材からなる。外装材３は、複数枚のサイディング材を横方向に接合して形成されたもので、軽量気泡コンクリート等の無機質系の材料から構成されている。外装材３は、その下端部３ｂが下耳部５の下端５ａより若干上方に位置するように貼設されている。外装材３の取付は、釘等の止着材（図示しない）を外側から外装材３と下耳部５とを貫通して壁パネル１１００の横芯材１００ｂに達するように打ち込むことによって行われる。
【００２６】
下耳部５は、床パネル１２の端部下面１２ｃまで延出される合板からなる帯板状のもであって、壁パネル１００の外側の面材１０４の下端部４ａに釘等の止着材（図示しない）によって固定されている。また、下耳部５は、壁パネル１００の下端４ｂから外方に突出した突出部５ｂと、突出部５ｂから壁パネル１００の内側に延出した延出部５ｃとから構成されている。そして、突出部５ｂと延出部５ｃは別個独立のものからなり、突出部５ｂの内側面に延出部５ｃを接着剤等で接着されている。また、突出部５ｂの厚みは、胴縁の厚みよりも薄く形成されている。また、下耳部５と外装材３との間には、水抜きパッキン５０が介在され、外装材３の裏面３ｄ側の水が抜けるようになっている。水抜きパッキン５０は、樹脂等で形成された帯板状の部材であって、水平方向に所定間隔で複数個設けられている。
【００２７】
２階の外装材付き壁パネル４は、壁パネル１００の下側の横框材１００ｂに設けられたボルト孔（図示しない）に、床パネル１２の端部上面１２ｂから突出した胴差しボルト（図示しない）を通して、該床パネル１２の端部上面１２ｂに固定支持され、さらに２階の外装材付き壁パネル４の内側の面材１０４から横框材１００ｂと床パネル１２の芯材１２ｄとを貫通させて胴差４１に達するように釘打ちすることにより接合されている。
【００２８】
また、床パネル１２の芯材１２ｄには、半月状の溝部（図示しない）が設けられ、１階の外装材付き壁パネル１０の上側の横框材１００ｂに設けられたボルト孔（図示しない）に通された胴差しボルト（図示しない）に、溝部（図示しない）が合わせられている。また、同様に、半月状の溝部（図示しない）を有する胴差し４１の溝部（図示しない）が胴差しボルト（図示しない）に合わせられている。そして、芯材１２ｄと胴差し４１は、外側から胴差し４１と芯材１２ｄを貫通して釘（図示しない）打ちされて固定されている。また、１階の外装材付き壁パネル１０と床パネル１２とは、１階の外装材付き壁パネル１０の面材４と横芯材１００ａを貫通して床パネル１２の芯材１２ｄと胴差し４１とにクロスさせて釘（図示しない）が打ち込まれて固定されている。よって、２階の外装材付き壁パネル１０の上端面１０ａに、床パネル１２の端部１２ａが支持されている。
【００２９】
１階（下側）の外装材付き壁パネル１０は、２階の外装材付き壁パネル４と同様に製造されるものであって、壁パネル１００の外側の面材１０４には、胴縁が横方向に伸びて貼設され、その上面には、外装材１１が貼設されている。また、１階の外装材付き壁パネル１０の外装材１１の上端１１ａは、２階の外装材付き壁パネル４の外装材３の下端３ａに近接して配置されている。
【００３０】
水切り６は、図２、図３および図６（ａ）に示すように、薄板状の塩ビ鋼板を折り曲げて断面視Ｚ状に形成し、取付部７と、この取付部７の下端に形成された水切り部８とを備え、外装材３の下端３ａに沿って延在するように形成されている。
【００３１】
取付部７は、２階の外装材付き壁パネル４の外装材３と、１階の外装材付き壁パネル１０の外装材１１との間１５から挿入されており、該取付部７の表面７ｄには透湿防水シート１０５が貼設され、前記間１５からビスなどの止着材Ｂが取付部７に打ち込まれ、下耳部５に取付けられている。
【００３２】
水切り部８は、外装材１１の上端１１ａ面に対して、取付部７の下端から外装材１１の表面上端部１１ｂに向かって、外装材１１の裏面１１ｄ側から表面１１ｃ側に傾斜するようにしてに配置され、外装材１１の上端１１ａ面を覆う延出部８ａと、この延出部８ａの先端部から下側外装材４の表面１１ｃに沿って下方に延出し、外装材１１の表面上端部１１ｂを覆う延出部８ｂと、この延出部８ｂの先端部から外装材１１の裏面１１ｄ側に向かって上方に延出する突起部８ｃとを備えている。
【００３３】
次に、図２（ａ）および（ｂ）に示すように、１階の外装材付き壁パネル４と２階の外装材付き壁パネル１０との間１５に水切り６を取付ける水切り６の取付構造を施工する水切り６の施工方法について説明する。
【００３４】
まず、１階の外装材付き壁パネル１０を基礎に取付けて、この１階の外装材付き壁パネル１０の上端面１０ａに接着剤を塗布し、床パネル１２の端部１２ａを取付ける。そして、床パネル１２の端部１２ａに胴差し４１を取付け、床パネル１２の芯材１２ｄと、１階の外装材付き壁パネル１０の上側の横框材１００ｂとに胴差しボルト（図示しない）を挿入し、外側から釘打ちすることによって、芯材１２ｄと胴差し４１とを固定する。次に、１階の外装材付き壁パネル１０の面材１０４と横框材１００ｂとを貫通して、床パネル１２の芯材１２ｄと胴差し４１とをクロスするように釘（図示しない）を打ち込み、床パネル１２の端部１２ａを１階の外装材付き壁パネル１０の上端面１０ａに支持させる。
【００３５】
次に、床パネル１２の端部上面１２ｂに接着剤を塗布し、２階の外装材付き壁パネル４の下端部４ａを取付ける。そして、２階の外装材付き壁パネル４の下側の横框材１００ｂと、床パネル１２の芯材１２ｄとに胴差しボルト（図示しない）を挿入する。そして、２階の外装材付き壁パネル４の内側の面材１０４から横框材１００ｂと床パネル１２の芯材１２ｄとを貫通し、胴差し４１に達するように釘打ちして、２階の外装材付き壁パネル４を床パネル１２の端部上面１２ｂに支持させることにより、１階の外装材付き壁パネル１０の外装材１１の上端１１ａと、２階の外装材付き壁パネル４の外装材３の下端３ａとを近接させる。
【００３６】
そして、取付部８を、２階の外装材付き壁パネル４の外装材３と、１階の外装材付き壁パネル１０の外装材１１との間１５から挿入して、取付部８の表面７ｄからビスなどの止着材Ｂを打ち込んで下耳部５に取付け、取付部８の表面７ｄに透湿防水シート１０５を貼設するとともに、水切り６の水切り部８によって、１階の外装材付き壁パネル１０の外装材１１の表面上端部１１ｂおよび上端１１ａ面を覆う。
【００３７】
以上のように、本実施の形態によれば、以下のような効果が得られる。
▲１▼１階の外装材１１の上端１１ａが、２階の外装材３の下端３ａに近接しているので、前記間１５の間隔を狭くすることができる。また、水切り６の取付部８が、前記間１５から挿入され、取付部８の裏面７ｅを下耳部５に取付け、水切り部８の延出部８ａ、８ｂが、１階の外装材付き壁パネル１０の外装材１１の表面上端部１１ｂおよび上端１１ａ面を覆っているので、雨水などの水の侵入を防止できる水切り６を容易に取付けることができる。よって、前記公報の技術のように、前記間１５を覆う幕板を取付ける必要がないので、幕板の取付け作業に係わる施工コスト、および幕板を現場に出荷するための輸送コストの低廉化が図れる。
【００３８】
▲２▼２階の外装材付き壁パネル４の下端部４ａに取付けられた下耳部５が床パネル１２の端部下面１２ｃまで延出されており、該下耳部５に位置する外装材３の下端３ａが下耳部５の下端５ａより若干上方に位置しているので、１階の外装材１１の上端１１ａと、２階の外装材３の下端３ａとを近接させることができる。
【００３９】
よって、上下の外装材３、１１を上下の壁パネル１００、１００に対して、連続的に取付けることができる。また、下耳部５が、床パネル１２の端部下面１２ｃまで延出されているので、床パネル１２の端部１２ａを覆うことができる。そして、下耳部５に位置する外装材３の下端３ａが、下耳部５の下端５ａより若干上方に位置しているので、２階の外装材付き壁パネル４を出荷する際や吊り込んで施工する際に、外装材３の下端部３ｂを保護することができる。また、水抜きパッキン５０によって、外装材３の裏面３ｂ側の水を容易に抜くことができる。
【００４０】
（第２の実施の形態）
第２の実施の形態の水切り６０の取付構造は、図１（ｂ）、図４〜図６（ｂ）に示すように、第１の実施の形態の水切り６を、水切り部６０に変更し、外装材付き小屋パネル（上側の外装材付き壁パネル）２０と２階（下側）の外装材付き壁パネル３０との間に水切り６０を取付けたものであって、その他の構成要素については、第１の実施の形態と同様である。したがって、水切り６０の取付構造において、第１の実施の形態の水切り６の取付構造と同一構成要素には同一符号を付して、その説明を省略する。
【００４１】
外装材付き小屋パネル３０は、屋根の下方に取付けられた外壁であって、第１の実施の形態の２階の外装材付き壁パネル４と同様に、壁パネル１００と、この壁パネル１００の外側の面材１０４に貼設された防水シート１０５と、この防水シート１０５上に取付けられた胴縁（図示しない）と、この胴縁に取付けられた外装材３１と、壁パネル１００の外側の面材１０４の下端部４ａに取付けられ、該壁パネル１００の下端４ｂより下方に突出する下耳部２５などにより概略構成され、予め工場で艤装されて製造される。
【００４２】
下耳部２５は、２階の外装材付き壁パネル２０の上端部表面２０ｂまで延出される合板からなる扁平な帯板状のもであって、第１の実施の形態と同様にして固定されている。また、下耳部２５と外装材３１との間には、第１の実施の形態と同様に、水抜きパッキン５０が介在され、外装材３１の裏面３１ｄ側の水が抜けるようになっている。
【００４３】
外装材付き小屋パネル３０は、この外装材付き小屋パネル３０の壁パネル１００の下側の横框材１００ｂに設けられたボルト孔（図示しない）に、２階の外装材付き壁パネル２０の上端面２０ａから突出した胴差しボルト（図示しない）を通して、２階の外装材付き壁パネル２０の上端面２０ａに固定支持されている。そして、外装材付き小屋パネル３０と２階の外装材付き壁パネル２０は、内側の面材１０４から外装材付き小屋パネル３０の横框材１００ｂと２階の外装材付き壁パネル２０の上側の横框材１００ｂとにそれぞれ達するようにクロスに釘Ａ打ちすることにより接合されている。
【００４４】
