【発明の属する技術分野】
本発明は、外装材が取り付けられた住宅の外壁構造に関する。
【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１９に示すような壁パネルが知られている。
【０００３】
図１９に示す壁パネル１００は、縦框材１０１，１０１と横框材１０２，１０２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芯材１０３…が縦横に組まれて枠体１０４が形成され、さらにこの枠体１０４内にグラスウール等の断熱材（図示省略）が充填された状態で枠体１０４の表裏面に合板等の面材１０５，１０５が貼設されたものである。
外壁用の壁パネルでは、更に、前記面材１０５，１０５に胴縁を取り付け、その上に外装材を取り付けていた。
しかし、胴縁は、所定の厚みを有する細板状の木材であるが、近年、安価に入手することが困難になっている。そこで、胴縁を使用しないで取付金具により外装材を取り付ける方法も知られている（例えば、特開平１０−３０６５０９号に開示されている）。
【０００４】
前記取付金具を用いた外装材の取付方法としては、例えば、図２０に示すような取付方法がある。
図２０において、外壁１１０の外面に縦方向に長いジョイナー１１１…を所定の間隔で取り付けた後、外装材１１２を下から上へ横貼りで取り付け、この際、取付金具１１３を所定の間隔に配置させて外装材１１２を取り付ける。即ち、取付金具１１３は、例えば、鉄板を抜き打ち、及び折曲加工したものからなり、下側の外装材１１２の端面部と係合する下係合部（図示省略）と、上側の外装材１１２の端面部と係合して支持する上係合部（図示省略）を有している。
そして、この取付金具１１３の下係合部を下側の外装材１１２の端面部に設けられた被係合部に係合させた状態で外壁１１０に取付金具１１３を固定し、更に、次の外装材１１２を該外装材１１２の下側端面部に設けられた被係合部と前記取付金具１１３の上係合部に係合させる。このような工程を繰り返すことにより、外装材１１２を壁の上端まで取り付ける。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記従来の横貼りによって外装材を外壁に取り付ける方法の場合には、外装材の横寸法のバラツキで変わってしまうと、ジョイナー部に形成される目地部の幅を均一にすることが難しく、目地幅を均一するためには、現場で外装材の一部を削る等の調整に手間がかかるという問題点があった。
また、その場合には、歩留まりが悪くなるという問題点があった。
加えて、従来の横貼りによる方法では、下から上に順番に取り付けるので、中間の外装材が破損した場合の外装材の取り替えも容易ではなかった。
更に、従来の取付金具は、外装材を支持するためののものであり、防水性の配慮がなされていなかった。従って、この従来の取付金具を縦貼りの場合に適用することはできなかった。
【０００６】
本発明は上記問題点を解決するためにされたものであって、取付金具を用いて目地幅を均一にすることが容易で防水性に優れ、且つ歩留まりのよい外壁構造を提供することを目的とする。
【０００７】
【課題を解決するための手段】
上記課題を解決するため、
請求項１記載の発明は、例えば、図１〜１５に示すように、住宅の外壁となる壁体１に、外装材４…が前記壁体１から所定幅離間して横方向に連なって取り付けられた外壁構造において、
前記外装材４の左右の側縁部４ａの裏面に、取付金具３が縦方向に所定の間隔で取り付けられ、
前記取付金具３は、前記壁体１に取り付けられる壁体取付部３ａ（例えば、凹部）と、該壁体取付部３ａに設けられ、前記壁体取付部３ａから所定幅離間して前記外装材４を取り付ける外装材取付部３ｃ（例えば、水平部）と、を有し、
前記壁体取付部３ａの少なくとも一部が前記外装材４の側縁部４ａよりも外側に位置するように、前記外装材取付部３ｃが前記外装材４の側縁部４ａの裏面に取り付けられ、
前記外装材４は、前記外装材４同士の側縁部４ａが所定の隙間４ｂ（例えば、目地部）を有しつつ、前記壁体１に取り付けられ、
前記隙間４ｂを埋める目地材１０が、前記外装材４の端面部４ｃに当接して取り付けられ、
前記壁体取付部３ａに防水性の中間部材９（例えば、樋）が設けられ、
前記中間部材９の両側面部９ａ、９ａには、その先端より外側に水平に突出した突出片９ｂ、９ｂが設けられ、該突出片９ｂ、９ｂは、前記外装材４と前記外装材取付部３ｃとに挟まれていることを特徴としている。
【０００８】
請求項１記載の発明によれば、外装材４の左右の側縁部４ａ、４ａの裏面に、取付金具３…が縦方向に所定の間隔で取り付けられ、取付金具３の壁体取付部３ａの少なくとも一部が側縁部４ａよりも外側に位置するように、外装材取付部３ｃが外装材４の側縁部４ａの裏面に取り付けられ、外装材４は、外装材４同士の側縁部４ａが所定の隙間を有しつつ、壁体１に取り付けられ、隙間４ｂを埋める目地材１０が、外装材４の端面部４ａに当接して取り付けられているので、外装材４を１枚１枚別個独立に壁体１に取り付けることが出来ることとなって、上下左右の誤差調整が出来て目地幅を均一にすることが出来る。
また、外装材４を取付後、補修が必要になった場合でも隣接する外装材４の影響を受けないで外装材４の取り替えが出来ることとなって、外装材４の交換作業が容易となる。
また、壁体取付部３ａの少なくとも一部が前記外装材４の側縁部４ａよりも外側に位置するように、取付金具３が外装材４に取り付けられているので、壁体１に壁体取付部３ａを固定することが容易に行われる。
更に、外装材４間の隙間を埋める目地材１０が取り付けられるので、隙間４ｂの防水を図ることが出来る。
加えて、この取付金具３を使用すれば、外装材４と壁体１とが離間することとなるので、胴縁が不要となる。
また、壁体取付部３ａに防水性の中間部材９が設けられているので、万が一、目地材１０と外装材４の間から水が内部に侵入した場合でも、中間部材９によって壁体１まで水が侵入することを防止出来、目地部４ｂの防水性を更に向上させることが出来る。
更に、中間部材９の両側面部９ａ、９ａには、その先端より外側に水平に突出して設けられた突出片９ｂ、９ｂが、外装材４と外装材取付部３ｃとに挟まれているので、中間部材９のずれが防止出来るとともに、外装材取付部３ｃと中間部材９との隙間が形成されにくい構造となって防水性が更に向上する。
【０００９】
ここで、取付金具３の外装材４への取付は、予め、工場で艤装してもよいし、現場で取り付けてもよい。
本発明が適用される壁体１は、例えば、在来工法によって構築されたものであってもよいし、２×４工法やパネル工法によって構築された壁体であってもよい。
外装材４及び壁体１への取付金具３の取付は、ビスや釘打ち、或いは接着剤を用いてもよい。
目地材１０は、乾式のものであってもよいし、或いは湿式のものであってもよい。
中間部材９は、防水性を有する材質のものであればよく、例えば、樹脂などを用いるがこれに限るものではない。また、防火性能を有する材料（例えば、ステンレス）で出来ている場合には、目地材に防火性を必要としない。
【００１０】
請求項２記載の発明は、例えば、図１〜１５に示すように、住宅の外壁となる壁体１に、外装材４…が前記壁体１から所定幅離間して横方向に連なって取り付けられた外壁構造において、
前記外装材４の左右の側縁部４ａの裏面に、取付金具３が縦方向に所定の間隔で取り付けられ、
前記取付金具３は、前記壁体１に取り付けられる壁体取付部３ａ（例えば、凹部）と、該壁体取付部３ａに設けられ、前記壁体取付部３ａから所定幅離間して前記外装材４を取り付ける外装材取付部３ｃ（例えば、水平部）と、を有し、
前記壁体取付部３ａの少なくとも一部が前記外装材４の側縁部４ａよりも外側に位置するように、前記外装材取付部３ｃが前記外装材４の側縁部４ａの裏面に取り付けられ、
前記外装材４は、前記外装材４同士の側縁部４ａが所定の隙間４ｂ（例えば、目地部）を有しつつ、前記壁体１に取り付けられ、
前記隙間４ｂを埋める目地材１０が、前記外装材４の端面部４ｃに当接して取り付けられ、
前記取付金具３の前記壁体取付部３ａは、断面略コ字状の凹部３ａを有し、外装材取付部３ｃは、前記凹部３ａを形成する２つの側面部３ｂの何れか一方の先端より外側に水平に突出した水平部３ｃを有し、
前記凹部３ａの少なくとも一部が前記外装材４の側縁部４ａよりも外側に位置するように、前記水平部３ｃの上面が前記外装材４の側縁部４ａの裏面に取り付けられ、
前記凹部３ａの底面部３ｅが前記壁体１に取り付けられていることを特徴としている。
【００１１】
請求項２記載の発明によれば、外装材４の左右の側縁部４ａ、４ａの裏面に、取付金具３…が縦方向に所定の間隔で取り付けられ、取付金具３の壁体取付部３ａの少なくとも一部が側縁部４ａよりも外側に位置するように、外装材取付部３ｃが外装材４の側縁部４ａの裏面に取り付けられ、外装材４は、外装材４同士の側縁部４ａが所定の隙間を有しつつ、壁体１に取り付けられ、隙間４ｂを埋める目地材１０が、外装材４の端面部４ａに当接して取り付けられているので、外装材４を１枚１枚別個独立に壁体１に取り付けることが出来ることとなって、上下左右の誤差調整が出来て目地幅を均一にすることが出来る。
また、外装材４を取付後、補修が必要になった場合でも隣接する外装材４の影響を受けないで外装材４の取り替えが出来ることとなって、外装材４の交換作業が容易となる。
また、壁体取付部３ａの少なくとも一部が前記外装材４の側縁部４ａよりも外側に位置するように、取付金具３が外装材４に取り付けられているので、壁体１に壁体取付部３ａを固定することが容易に行われる。
更に、外装材４間の隙間を埋める目地材１０が取り付けられるので、隙間４ｂの防水を図ることが出来る。
加えて、この取付金具３を使用すれば、外装材４と壁体１とが離間することとなるので、胴縁が不要となる。
また、取付金具３の壁体取付部３ａは、断面略コ字状の凹部３ａを有し、外装材取付部３ｃは、凹部３ａを形成する２つの側面部３ｂの何れか一方の先端より外側に水平に突出した水平部３ｃを有し、凹部３ａの少なくとも一部が外装材４の側縁部４ａよりも外側に位置するように、水平部３ｃの上面が前記外装材４の側縁部４ａの裏面に取り付けられ、凹部３ａの底面部３ｅが壁体１に取り付けられているので、取付金具３の形状が製造し易いものとなって、取付金具３の製造コストを抑えることが出来る。
より具体的には、本発明の外壁構造に用いられる取付金具３は、例えば、図２に示したような形状から出来ているので、一枚の金属板を折曲加工すれば、製造することが出来て、取付金具３自体のコストを抑えることが出来る。
加えて、本発明の外壁構造に用いられる取付金具３は、左右の外装材４の側縁部４ａで構造上異なることがないので、左右兼用することとが出来ることとなって、取付金具３の種類が一つでよくコスト及び在庫管理上好ましいものとなる。
【００１２】
請求項３記載の発明は、請求項１又は２記載の外壁構造において、
前記目地材４１は、乾式の目地材４１であり、その内部には、防火性を有する補強用部材４４が挿入されていることを特徴としている。
【００１３】
請求項３記載の発明によれば、請求項１又は２記載の発明と同等の効果が得られることは無論のこと、特に、目地材４１は、乾式の目地材であり、その内部には、防火性を有する補強用部材４４が挿入されているので、目地部４ｂの防火を図ることが出来る。
【００１４】
請求項４記載の発明は、請求項３記載の外壁構造において、
前記外装材４の側端面部４ｃには、所定の溝部４ｄが設けられ、該溝部４ｄに前記目地材４１の側縁部４１ａが挿入されていることを特徴としている。
【００１５】
請求項４記載の発明によれば、請求項３記載の発明と同様の効果が得られることは無論のこと、特に、外装材４の側端面部４ｃには、所定の溝部４ｄが設けられ、該溝部４ｄに目地材４１の側縁部４１ａが挿入されているので、意匠性を高めることが出来る。
即ち、従来は、目地材４１の側縁部４１ａが折れ曲がって外装材４の側端面部４ｃに当接していたため、目地面が平らでなく見た目がよくない場合もあったが、溝部４ｄに目地材４１の側縁部４１ａが挿入されているので、目地面が平らとなって見た目がよくなる。
【００１７】
請求項５記載の発明は、請求項３又は４記載の外壁構造において、
前記目地材４１には、幅方向断面視において、その先端部４１ｃ及び中間部４１ｂの少なくとも何れか一方に、所定の弾性変形能を有するフィン部４３ｂ、４３ｃが設けられていることを特徴としている。
【００１８】
請求項５記載の発明によれば、請求項３又は４記載の発明と同様の効果が得られることは無論のこと、特に、目地材４１には、幅方向断面視において、その先端部４１ｃ及び中間部４１ｂの少なくとも何れか一方に設けられた所定の弾性変形能を有するフィン部４３ｂ、４３ｃが、外装材４と密着して目地部４ｂの防水性を向上させることが出来る。
【００１９】
ここで、所定の弾性変形能を有するフィン部４３ｂ、４３ｃとは、フィン部４３ｂ、４３ｃが外装材４に当たった場合に、弾性変形し、その力によって、当接部の防水性を確保するものであり、防水性が発揮出来る程度の弾性変形能を必要とする。
【００２４】
請求項６記載の発明は、図１６〜図１８に示したように、住宅の外壁となる壁体１に、外装材が前記壁体１から所定幅離間して横方向に連なって取り付けられた外壁構造において、
前記外装材８０の左右の側縁部８０ａ、８０ｂの何れか一方の裏面に取り付けられた第１の係合部材７１と、他方の側縁部８０ｂの裏面に取り付けられた前記第１の係合部材７１と係合する第２の係合部材７２と、が左右一対で縦方向に所定の間隔で取り付けられ、
前記第１の係合部材７１は、前記第２の係合部材７２と係合する係合部７１ｃを有し、
前記第２の係合部材７２は、前記第１の係合部材７１の前記係合部７１ｃと係合可能な被係合部７２ａを有し、
前記係合部７１ｃ或いは前記被係合部７２ａの何れか一方が前記外装材８０の側縁部８０ａ、８０ｂよりも外側に位置するように取り付けられ、
隣接する前記外装材８０のうち、一方の外装材８０の前記第１の係合部材７１の前記係合部７１ｃと、他方の外装材８０の前記第２の係合部材７２の前記被係合部７２ａとが係合することにより、前記外装材８０は、前記外装材８０同士の側縁部８０ａ、８０ｂが所定の隙間を有しつつ、前記壁体１に取り付けられ、
前記隙間を埋める目地材１０が、前記外装材８０の端面部８０ａ、８０ｂに当接して取り付けられていることを特徴としている。
【００２５】
請求項６記載の発明によれば、外装材８０を壁体１に取り付ける場合に、外装材８０の左右の側縁部８０ａ、８０ｂに各々設けられた第１、第２の係合部材７１、７２のうち、第１の係合部材７１が壁体１に固定され、第２の係合部材７２は、第１の係合部材７１と係合して取り付けられるので、第２の係合部材７２が設けられた側縁部８０ｂは、壁体１に直接固定する必要がなく工程を簡略化させることが出来る。
また、外装材８０を取付後、補修が必要になった場合でも隣接する外装材８０の第１の係合部材７１と他方の第２係合部材７２の係合を外すことにより外装材８０の取り替えが出来ることとなって、外装材８０の交換作業が容易となる。
更に、外装材８０間の隙間を埋める目地材が取り付けられるので、目地部の防水を図ることが出来る。
また、この第１の係合部材７１、第２の係合部材７２を使用すれば、外装材８０と壁体１とが離間することとなるので、胴縁が不要となる。
【００２６】
請求項７記載の発明は、住宅の外壁となる壁体１に、外装材８０が前記壁体１から所定幅離間して横方向に連なって取り付けられた外壁構造において、
前記外装材８０の左右の側縁部８０ａ、８０ｂはそれぞれ上サネ８２と下サネ８１を有しており、前記外装材８０の左右の側縁部８０ａ、８０ｂの何れか一方の裏面に取り付けられた第１の係合部材７１と、他方の側縁部８０ｂの裏面に取り付けられた前記第１の係合部材７１と係合する第２の係合部材７２と、が左右一対で縦方向に所定の間隔で取り付けられ、
前記第１の係合部材７１は、前記第２の係合部材７２と係合する係合部７１ｃを有し、
前記第２の係合部材７２は、前記第１の係合部材７１の前記係合部７１ｃと係合可能な被係合部７２ａを有し、
前記係合部７１ｃ或いは前記被係合部７２ａの何れか一方が前記外装材８０の側縁部８０ａ、８０ｂよりも外側に位置するように取り付けられ、
隣接する前記外装材８０のうち、一方の外装材８０の第１の係合部材７１の前記係合部７１ｃと、他方の外装材８０の前記第２の係合部材７２の被係合部７２ａとが係合し、隣接する一方の前記外装材８０の上サネ８２と他方の前記外装材８０の下サネ８１とが重なるように取り付けられていることを特徴としている。
【００２７】
請求項７記載の発明によれば、外装材８０を壁体１に取り付ける場合に、外装材８０の左右の側縁部８０ａ、８０ｂに各々設けられた第１、第２の係合部材７１、７２のうち、第１の係合部材７１が壁体１に固定され、第２の係合部材７２は、第１の係合部材７１と係合して取り付けられるので、第２の係合部材７２が設けられた側縁部８０ｂは、壁体１に直接固定する必要がなく工程を簡略化させることが出来る。
また、外装材８０を取付後、補修が必要になった場合でも隣接する外装材８０の第１の係合部材７１と他方の第２係合部材７２の係合を外すことにより外装材８０の取り替えが出来ることとなって、外装材８０の交換作業が容易となる。
更に、隣接する一方の外装材８０の上サネ８２と他方の外装材８０の下サネ８１とが重なるように取り付けられているので、別個に目地材を設けなくても外装材８０同士の繋ぎ目の防水性を図ることが出来る。
また、この第１の係合部材７１、第２の係合部材７２を使用すれば、外装材８０と壁体１とが離間することとなるので、胴縁が不要となる。
【００３０】
【発明の実施の形態】
以下、図を参照して本発明に係る外壁構造、および取付金具を用いた外装材の取付方法の実施の形態について詳細に説明する。
［第１の実施の形態］
図１は、外装材が取り付けられた外壁構造を示した斜視図であり、図２は、第１の実施の形態の金具の斜視図である。
図１に示す外壁構造における壁体１は、矩形状の壁パネル２…を連結したものから構成されている。
【００３１】
前記壁パネル２は、縦框材２ａ、２ａと横框材２ｂ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芯材（図示省略）が縦横に組まれて枠体が形成され、さらにこの枠体内にグラスウール等の断熱材（図示省略）が充填された状態で枠体の表裏面に合板等の面材２ｃ、２ｄが貼設されたものである。
前記面材２ｃ、２ｄのうち、室外側の面材２ｃには、図示しない防水シートが貼設された後、取付金具３…（取付金具）を介して、外装材４…が取り付けられている。
【００３２】
前記取付金具３は、図２に示すように、断面略コ字状の凹部３ａ（壁体取付部）と、該凹部３ａを形成する２つの側面部３ｂ、３ｂの一方の先端より外側に水平に突出した水平部３ｃ（外装材取付部）と、前記凹部３ａと前記水平部３ｃとの間に設けられた傾斜部３ｄと、を有している。
そして、前記取付金具３の前記水平部３ｃの上面は、図３に示すように、前記外装材４の側縁部４ａの下面に接着剤およびビス５によって固定されている。この際、前記凹部３ａの少なくとも一部が外装材４の側縁部４ａよりも外側に突出して取り付けられる。
また、前記取付金具３は、前記外装材４の左右の側縁部４ａに沿って所定の間隔で取り付けられるとともに、左右の側縁部４ａ、４ａでは取付金具３が取り付けられる位置がずらされている。従って、この外装材４を順次壁パネル２の面材２ｃに取り付ける場合、隣接する外装材４、４の取付金具３同士がぶつかることなく、壁パネル２に取り付けることが出来るようになっている。
【００３３】
壁パネル２の下端の横框材２ｂに固定された調整材６には、図４に示すように、外装材４、４を支持する下端金具７がスクリュー釘８若しくはビス等によって固定され、該下端金具７の外装材支持部７ａに、前記外装材４、４が支持されるようになっている。
【００３４】
また、隣接する前記外装材４、４の側縁部４ａ、４ａに形成される目地部４ｂには、図５、或いは図６に示すように、ポリエチレン等の樹脂からなる樋９（中間部材）と、目地材１０を固定する目地受け材１１が差し入れられ、その上から、該目地受け材１１、樋９、凹部３ａ、面材２ｃを貫通してビス１２が打ち込まれ、これにより取付金具３が前記壁パネル２に固定される。更に、その上からは、隙間を埋める目地材１０が、外装材４の端面部４ｃ、４ｃに当接して取り付けられている。
【００３５】
前記樋９は、前記取付金具３の凹部３ａの内壁に密着する大きさのコ字状の形状を有し、その両側面部９ａ、９ａの先端からは外側に突出して突出片９ｂ、９ｂが設けられ、図６に示すように、この突出片９ｂ、９ｂが前記水平部３ｃと外装材４に挟まれることとなって樋９のずれを防止することが出来るとともに、防水性も向上する。
また、この取付金具３…を使用した外装材４の取付では、外装材４と壁パネル２が所定幅離間して設けられることとなって、この取付金具３が従来の胴縁の役割を果たしている。
【００３６】
次に、上記外壁構造における外装材の取付作業動作について、図７を用いて説明する。
まず、予め、外装材４の側縁部４ａに、取付金具３…を左右互い違いに所定間隔で取り付ける。次いで、この外装材４の下端を壁パネル２に取り付けられた下端金具７で支持し、凹部３ａの底面部３ｅを接着剤等で仮止め（必ずしも必要ない）し、次いで、次なる外装材４を側縁部４ａ同士が所定の隙間を有するように仮止めする。次いで、この隙間に、樋９と、目地受け材１１を挿入して、前記底面部を３ｅを貫通するようにビス１２を打ち込み、その上から目地材１０を目地受け材１１に固定する。上記作業を繰り返して行うことにより、壁パネル２に外装材４を取り付ける。
【００３７】
次に、外装材４の交換作業について図７を用いて説明する。
まず、交換しようとする当該外装材４の左右の目地部４ｂの目地材１３を外した後、ビス１２止めを外して目地受け材１１、樋９を外す。この状態で、外装材４を左右どちらかに寄せる（例えば、図７のように右側に寄せる）。次いで、目地部４ｂの隙間が広がった方の外装材４の側縁部４ａを上に持ち上げて、図７中の矢印方向に外装材４を引き抜くことにより外装材４を壁パネル２から外すことが出来る。また同様に、今度は、逆の動作により新しい外装材４を入れることが出来る。即ち、予め、所定位置に取付金具３が取り付けられた外装材４を図７中の矢印と反対方向に差し入れる。次いで、外装材４を左右に動かして、左右に隣接する外装材４、４との目地部４ｂの隙間間隔を調整した後、該目地部４ｂに樋９と目地受け材１１を挿入し、ビス１２打ち後、目地材１０を挿入する。
【００３８】
以上説明した本発明の第１の実施の形態の外壁構造および外装材４の取付方法によれば、外装材４の左右の側縁部４ａ、４ａの裏面に、取付金具３…が縦方向に所定の間隔で取り付けられ、取付金具３…の底面部３ｅの少なくとも一部が側縁部４ａ、４ａよりも外側に位置するように、水平部３ｃが外装材４の側縁部４ａ、４ａの裏面に取り付けられ、外装材４は、外装材４同士の側縁部４ａ、４ａが所定の隙間を有しつつ、壁体１に底面部３ｅが固定されることにより取り付けられ、隙間を埋める目地材１０が、外装材４の端面部４ｃ、４ｃに当接して取り付けられているので、外装材４を１枚１枚別個独立に壁体１に取り付けることが出来ることとなって、上下左右の誤差調整が出来て目地幅を均一にすることが出来る。
【００３９】
また、外装材４を取付後、補修が必要になった場合でも隣接する外装材４の影響を受けないで外装材４の取り替えが出来ることとなって、外装材４の交換作業が容易となる。
また、凹部３ａの少なくとも一部が前記外装材４の側縁部４ａ、４ａよりも外側に位置するように、取付金具３が外装材４に取り付けられているので、壁体１に外装材４を固定することが容易に行われる。
更に、外装材４、４間の隙間を埋める目地材１０によって、目地部４ｂの防水を図ることが出来る。
加えて、この取付金具３を使用すれば、外装材４と壁体１とが離間することとなるので、胴縁が不要となる。
【００４０】
なお、上記第１の実施の形態の外壁構造は、図８〜図１５に示す外壁構造に応用することが出来る。
図８、図９に示す第２の外壁構造２０において、取付金具２１は、凹部２１ａと、該凹部２１ａの一方の側面部２１ｂの先端から外方に水平に突出した水平部２１ｃと、を備え、前記凹部２１ａの底面部２１ｄは、前記壁パネル２にビス２２によって固定され、前記水平部２１ｃは、前記外装材４の側縁部４ａの裏面にビス２３等によって固定されている。
前記凹部２１ａは、二重底構造となっていて、中間に水平な仕切り板２１ｅが設けられ、該仕切り板２１ｅには、ビス２２の頭部の外径よりも若干大きな穴２１ｆが設けられている。そして、先に取付金具２１をビス２２に壁パネル２に取り付け、その後に、樋２４、目地受け材２５、目地材２６を取り付けることが出来るようになっている。これにより、外装材４の壁パネル２への取付工程と、目地部４ｂを埋める目地部処理工程を分離することが出来ることとなって作業性が向上される。

図１０、図１１に示す第３の外壁構造３０においては、予め、取付金具３１にポリエチレン製の樋３２を嵌めこんでおき、その上から、目地受け材３３、目地材３４を取り付けたものであり、取付金具と防水性を有する樋３２とを一体化することにより、防水性の向上を図るとともに、目地部４ｂの目地部処理の簡略化を図ったものである。
【００４２】
図１２に示す第４の外壁構造４０は、樋と、目地受け材を無くし、目地材４１を外装材４と取付金具４２に嵌め込むものである。より具体的には、この目地材４１は、頭部４１ａ（側端縁部）、中間部４１ｂ、及び先端部４１ｃの三ヶ所に、それぞれフィン部４３ａ〜４３ｃが設けられ、内部には、補強用と防火性確保のため鉄製の補強用材４４が挿入され、外部はポリエチレン樹脂で覆われている。
取付金具４２は、凹部４２ａと、該凹部４２ａの一方の側面部４２ｂの先端から外方に水平に突出した水平部４２ｃと、を備え、前記凹部４２ａの底面部４２ｄは、前記壁パネルの面材２ｃにビス４５によって固定され、前記水平部４２ｃは、前記外装材４の側縁部４ａの裏面にビス４６等によって固定されている。
また、前記外装材４の側端面部４ｃ、４ｃには、予め溝部４ｄ、４ｄが設けられ、この溝部４ｄに前記目地材４１の頭部４１ａのフィン部４３ａが差し込まれている。これにより、目地部４ｂの見栄えがよくなる。即ち、従来は、目地材４１の側縁部４１ａが折れ曲がって外装材４の側端面部４ｃに当接していたため、目地面が平らでなく見た目がよくない場合もあったが、溝部４ｄに目地材４１の側縁部４１ａが挿入されているので、目地面が平らとなって見た目がよくなる。
また、目地部４ｂの防水を図ることが出来る。また、中間部４１ｂのフィン部４３ｂ、先端部４１ｃのフィン部４３ｃは、弾性変形して外装材４と密着することにより、更に目地部４ｂの防水性の向上が図られている。
【００４３】
図１３に示す第５の外壁構造５０において、取付金具５１は、凹部５１ａと、該凹部５１ａの一方の側面部５１ｂの先端から外方に水平に突出した水平部５１ｃと、を備え、前記凹部５１ａの底面部５１ｄは、前記壁パネル２の面材２ｃにスクリュー釘５２若しくはビス等によって固定され、前記水平部５１ｃは、前記外装材４の側縁部４ａの裏面にビス５３等によって固定されている。
そして、水平部５１ｃの設けられていないもう一方の側面部５１ｂの先端に、目地材５４の先端部５４ａのフィン部５４ａと係合する係合部５１ｅを設けたものであり、これにより、目地材５４の取付後の安定性の向上が図られている。
【００４４】
図１４、図１５に示す第６の外壁構造６０は、第４、第５の外壁構造４０、５０における目地材４１、５４と同じ目地材６１を用いる。取付金具６２は、凹部６２ａと、該凹部６２ａの一方の側面部６２ｂの先端から外方に水平に突出した水平部６２ｃと、を備え、前記凹部６２ａの底面部６２ｄは、前記壁パネル２の面材２ｃにスクリュー釘６３或いはビス等によって固定され、前記水平部６２ｃは、前記外装材４の側縁部４ａの裏面にビス６４等によって固定されている。
前記側面部６２ｂと前記水平部６２ｃとの間には凹み部６２ｅが形成され、外装材４が取り付けられた際に該凹み部６２ｅによって隙間が形成されるようになっている。
この凹部６２ｅによって、壁体に取り付けられた外装材４を斜めに傾けることが出来ることとなって、目地材６１が取り付けられる目地部の外装材４をハの字に持ち上げることが出来る。従って、この目地部に防水紙が重ねられた場合でも、隣接する外装材４を持ち上げることにより防水紙を２重に重ねた後に取付金具４を固定することによって、防水紙を２重に重ねることが出来る。
即ち、隣接する外装材４の一方の取付金具６２を先に取り付けてしまうと防水紙を２重に重ねることは出来ないが、凹部６２ｅによって外装材４が斜めに持ち上げることが出来るので、防水紙を取付金具６２の内側に挟み込むことが出来る。
【００４５】
［第２の実施の形態］
図１６は、第２の実施の形態の取付金具が取り付けられた外装材の正面図であり、図１７は、この取付金具を用いた外装材の壁体への取付構造を示した図である。
図１６、１７に示す第２の実施の形態の取付金具７０は、外装材８０の下サネ８１を有する側縁部８０ａの下面に設けられる断面略コ字状の凹部７１ａと、該凹部７１ａを形成する２つの側面部７１ｂ、７１ｂの一方の先端より外側に水平に突出するとともに、その先端にフック状の係合部７１ｃを有する水平部７１ｄと、からなる第１の係合部材７１と、外装材８０の上サネ８２を有する側縁部８０ｂに設けられる断面が略コ字状であり、且つ前記第１の係合部材７１の係合部材７１ｃと係合可能なフック状の被係合部７２ａを備えた第２の係合部材７２と、から構成されている。
【００４６】
前記外装材８０の側縁部８０ａ、８０ｂの上サネ８２と下サネ８１は係合するようになっている。
前記第１の係合部材７１は、その凹部７１ａの底面部７１ｅが前記外装材８０の側縁部８０ａの下面に接着剤およびビス７３によって固定されている。この際、前記係合部７１ｃが外装材８０の側縁部８０ａよりも外側に突出して取り付けられる。
【００４７】
前記第２の係合部材７２は、その底面部７２ｂが前記外装材８０の側縁部８０ｂの下面に接着剤およびビス７３によって固定されている。
前記第１の係合部材７１と第２の係合部材７２は、前記外装材８０の水平方向の位置において同一線上に一対で設けられているとともに、垂直方向に所定の間隔で取り付けられている。
そして、この外装材８０を順次壁パネル２の面材２ｃに取り付ける際、前記第１の係合部材７１の水平部７１ｄをスクリュー釘７４によって壁パネルの面材２ｃに取り付けた後、前記係合部７１ｃに、前記第２の係合部材７２の被係合部７２ａを引っかけて固定する。
また、この取付金具７０…を使用した外装材８０の取付では、外装材８０と壁パネルが所定幅離間して設けられることとなって、この取付金具７０が従来の胴縁の役割を果たしている。
【００４８】
次に、上記外壁構造における外装材の取付作業動作について、図１８を用いて説明する。
まず、予め、外装材８０の側縁部８０ａ、８０ｂに、第１の係合部材７１と第２の係合部材７２を左右一対として所定間隔で取り付ける。次いで、この外装材８０の下端を壁パネルに取り付けられた下端金具（図示省略）に支持し、水平部７１ｄをスクリュー釘７４によって面材２ｃに固定し、次いで、次なる外装材８０を側縁部８０ｂの下面に設けられた第２の係合部材７２の被係合部７２ａと隣接する外装材の側縁部８０ａの下面に設けられた第１の係合部材７１の係合部７１ｃに係合させて取り付ける。この際、隣接する外装材８０、８０の上サネ８２と下サネ８１が重なるように取り付ける。そして、上記作業を繰り返して行うことにより、壁パネル２の面材２ｃに外装材８０を取り付ける。
【００４９】
次に、上記外壁構造における外装材８０の交換作業動作について説明する。
まず、当該外装材８０の第１の係合部材７１と係合する隣接する外装材８０の第２の係合部材７２との係合を解除し、スクリュー釘７４を取り外す。次いで、当該外装材８０の第２の係合部材７２の被係合部７２ａを隣接する外装材８０の第１の係合部材７１の係合部７１ｃから外す。次いで、当該外装材８０の側縁部８０ｂを上に持ち上げて、図１８中の矢印方向に当該外装材８０を引き抜くことにより当該外装材８０を壁パネルの面材２ｃから外すことが出来る。また同様に、今度は、逆の動作により新しい外装材８０を入れることが出来る。即ち、予め、所定位置に取付金具７０が取り付けられた外装材８０を図１８中の矢印と反対方向に差し入れる。次いで、外装材８０を左右に動かして、隣接する外装材８０、８０の上サネ８２と下サネ８１とが重なるように調整した後、第１の係合部材７１の水平部７１ｄをスクリュー釘７４打ちして壁パネル２に取り付ける。次いで、当該外装材８０の第１の係合部材７１と、隣接する外装材８０の第２の係合部材７２とを係合させることにより、当該外装材８０を壁パネル２の面材２ｃに取り付ける。
【００５０】
以上説明した本発明の外壁構造によれば、外装材８０、８０の左右の側縁部８０ａ、８０ｂに各々設けられた第１、第２の係合部材７１、７２のうち、第１の係合部材７１が壁パネル２に固定され、第２の係合部材７２は、第１の係合部材７１と係合して取り付けられるので、第２の係合部材７２が設けられた側縁部８０ｂは、壁パネル２に直接固定する必要がなく工程を簡略化させることが出来る。
また、外装材８０を取付後、補修が必要になった場合でも隣接する外装材８０の第１の係合部材７１と他方の第２係合部材７２の係合を外すことにより外装材８０の取り替えが出来ることとなって、外装材８０の交換作業が容易となる。
更に、隣接する一方の外装材８０の上サネ８２と他方の外装材８０の下サネ８１とが重なるように取り付けられているので、別個に目地材を設けなくても外装材８０、８０同士の繋ぎ目の防水性を図ることが出来る。
また、この取付金具７０を使用すれば、外装材８０と壁パネル２とが離間することとなるので、胴縁が不要となる。
【００５１】
なお、上記第２の実施の形態においては、外装材８０の側縁部がサネ構造になっている場合について例示したが、側端面が平面で、別途目地材を取り付けた外壁構造にも適用可能なことは、無論であり、その場合には、第１の実施の形態で説明した目地材を用いてもよい。
また、上記実施の形態においては、パネル工法を例として説明したが、在来の軸組工法やツーバイフォー工法によって構築された外壁にも適用可能であることは無論である。

BACKGROUND OF THE INVENTION
  The present invention provides a housing with an exterior material attached.Exterior wall structureAbout.
[0002]
[Background technology]
In recent years, the construction of houses has been industrialized. For example, there is a panel construction method in which components such as walls, floors, and roofs are made into panels in the factory in advance and these panels are assembled at the construction site to construct the house. Adopted in some areas.
As a panel used for such a panel method, for example, a wall panel as shown in FIG. 19 is known.
[0003]
A wall panel 100 shown in FIG. 19 includes a vertical frame member 101, 101 and a horizontal frame member 102, 102 assembled in a rectangular shape, and a reinforcing core member 103, which is assembled vertically and horizontally inside the rectangular frame. 104 is formed, and face materials 105 and 105 such as plywood are pasted on the front and back surfaces of the frame body 104 in a state in which the frame body 104 is filled with a heat insulating material such as glass wool (not shown). .
In the wall panel for the outer wall, a body edge is attached to the face members 105 and 105, and an exterior material is attached thereon.
However, although the trunk edge is a thin plate-like wood having a predetermined thickness, it has recently become difficult to obtain it at a low cost. In view of this, a method of attaching an exterior material with an attachment fitting without using a trunk edge is also known (for example, disclosed in JP-A-10-306509).
[0004]
As an attachment method of the exterior material using the attachment fitting, for example, there is an attachment method as shown in FIG.
20, after long joiners 111 are attached to the outer surface of the outer wall 110 in a vertical direction at a predetermined interval, the exterior material 112 is attached laterally from the bottom to the top. At this time, the mounting brackets 113 are arranged at a predetermined interval. The exterior material 112 is attached. That is, the mounting bracket 113 is formed by punching and bending an iron plate, for example, and includes a lower engagement portion (not shown) that engages with an end surface portion of the lower exterior material 112 and an upper exterior material 112. And an upper engaging portion (not shown) that is engaged with and supported by the end surface portion.
Then, the mounting bracket 113 is fixed to the outer wall 110 in a state where the lower engaging portion of the mounting bracket 113 is engaged with the engaged portion provided on the end surface portion of the lower exterior material 112, and the following The exterior material 112 is engaged with the engaged portion provided on the lower end surface portion of the exterior material 112 and the upper engagement portion of the mounting bracket 113. By repeating such a process, the exterior material 112 is attached to the upper end of the wall.
[0005]
[Problems to be solved by the invention]
However, in the case of the method of attaching the exterior material to the outer wall by the above-mentioned conventional lateral bonding, it is difficult to make the width of the joint portion formed in the joiner portion uniform if the lateral dimension of the exterior material changes. In order to make the joint width uniform, there is a problem in that it takes time and effort to adjust a part of the exterior material at the site.
In that case, there is a problem that the yield is deteriorated.
In addition, in the conventional method of horizontal pasting, since the attachment is performed sequentially from the bottom to the top, it is not easy to replace the exterior material when the intermediate exterior material is damaged.
Furthermore, the conventional mounting bracket is for supporting the exterior material, and no consideration has been given to waterproofness. Therefore, this conventional mounting bracket cannot be applied to the case of vertical bonding.
[0006]
  The present invention has been made to solve the above-mentioned problems, and it is easy to make the joint width uniform using a mounting bracket, is excellent in waterproofness, and has a good yield.Exterior wall structureThe purpose is to provide.
[0007]
[Means for Solving the Problems]
  To solve the above problem,
  In the first aspect of the invention, for example, as shown in FIGS. 1 to 15, an exterior material 4... In the outer wall structure,
  Mounting brackets 3 are attached to the back surfaces of the left and right side edge portions 4a of the exterior material 4 at predetermined intervals in the vertical direction,
  The mounting bracket 3 is provided on the wall body mounting portion 3a (for example, a recess) to be mounted on the wall body 1 and the wall body mounting portion 3a, and is spaced apart from the wall body mounting portion 3a by a predetermined width. An exterior material mounting portion 3c (for example, a horizontal portion) for mounting 4;
  The exterior material attachment portion 3c is attached to the back surface of the side edge portion 4a of the exterior material 4 so that at least a part of the wall body attachment portion 3a is located outside the side edge portion 4a of the exterior material 4. ,
  The exterior material 4 is attached to the wall body 1 while the side edges 4a of the exterior materials 4 have predetermined gaps 4b (for example, joints),
  A joint material 10 filling the gap 4b is attached in contact with the end surface portion 4c of the exterior material 4.,
A waterproof intermediate member 9 (for example, a collar) is provided on the wall body attaching portion 3a,
Protruding pieces 9b, 9b are provided on both side surface portions 9a, 9a of the intermediate member 9 so as to protrude horizontally outward from the tips thereof. The protruding pieces 9b, 9b are formed by the exterior material 4 and the exterior material mounting portion 3c. Sandwiched betweenIt is characterized by that.
[0008]
  According to the first aspect of the present invention, the mounting brackets 3 are attached to the back surfaces of the left and right side edge portions 4a and 4a of the exterior material 4 at predetermined intervals in the vertical direction, and the wall body mounting portion 3a of the mounting bracket 3 is provided. The exterior material attaching portion 3c is attached to the back surface of the side edge portion 4a of the exterior material 4 so that at least a part of the exterior material 4 is located outside the side edge portion 4a. Since the joint material 10 that is attached to the wall body 1 and fills the gap 4b is attached in contact with the end surface portion 4a of the exterior material 4 while the portion 4a has a predetermined clearance, one exterior material 4 is provided. One sheet can be attached to the wall 1 independently, and the vertical and horizontal error adjustments can be made and the joint width can be made uniform.
  In addition, even when repair is necessary after the exterior material 4 is attached, the exterior material 4 can be replaced without being affected by the adjacent exterior material 4, so that the exterior material 4 can be easily replaced. .
  Further, since the mounting bracket 3 is attached to the exterior material 4 so that at least a part of the wall body attachment portion 3a is located outside the side edge 4a of the exterior material 4, the wall body 1 is attached to the wall body 1. It is easy to fix the mounting portion 3a.
  Furthermore, since the joint material 10 which fills the gap between the exterior materials 4 is attached, the waterproof of the gap 4b can be achieved.
  In addition, if the mounting bracket 3 is used, the exterior material 4 and the wall body 1 are separated from each other, so that a trunk edge is not necessary.
Moreover, since the waterproof intermediate member 9 is provided in the wall attachment part 3a, even if water penetrates into the inside from between the joint material 10 and the exterior material 4, the intermediate member 9 leads to the wall body 1. Water can be prevented from entering, and the waterproofness of the joint 4b can be further improved.
Furthermore, since the projecting pieces 9b and 9b provided on both side surface portions 9a and 9a of the intermediate member 9 so as to protrude horizontally outward from the tip end are sandwiched between the exterior material 4 and the exterior material mounting portion 3c. The displacement of the intermediate member 9 can be prevented, and the waterproof property is further improved since the gap between the exterior material attaching portion 3c and the intermediate member 9 is difficult to be formed.
