【発明の属する技術分野】
本発明は、外装材を壁体の外面に取り付ける外装材取付構造、および外装材取付方法に関するものである。
【０００２】
【背景の技術】
近年、住宅等の建物の構築にお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、建物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１１に示すような壁パネル２が知られている。この壁パネル２は、縦框材２０１，２０１と横框材２０２，２０２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２０３，…が縦横に組まれて枠体２０４が形成され、さらにこの枠体２０４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２０４の表裏面に合板等の面材２０５，２０５が貼設されたものである。さらに工場等において、外壁用の壁パネルの外面に予め外装材を取り付けておき、建築現場で組み立てることにより、現場工期をより一層短縮できる壁パネルの艤装化も行われている。
【０００３】
このような壁パネル２の外面に外装材を取り付ける従来の技術としては、図１２に示すように、一方のサイディング材１１０には、左側サネ部１１２が形成されており、他方のサイディング材１１８には右側サネ部１２８が形成されている。これらサイディング材１１８，１１０は、右側サネ部１２８の外側に左側サネ部１１２が位置するようにして配置されている。そして、外壁基礎材（壁パネル）１３２の表面には胴縁１２２が固定されており、固定材（釘）１２６を、サイディング材１１０の表面から胴縁１２２まで到達するようにして外壁基礎材（壁パネル）１３２にサイディング材１１０を取り付けている（例えば、特許文献１参照。）。

【発明が解決しようとする課題】
上記の従来の技術では、次のような課題があった。
第１に、釘打ち等によりサイディング材１１０を取り付けるようにしているので、サイディング材１１０どうしを実矧ぎによって接合しつつ、これらサイディング材１１０を壁に取り付けるのに手間がかかるうえに、サイディング材１１０の表面に固定材１２６が露出するため、表面処理作業を行う必要があるという問題があった。
第２に、壁パネルの艤装化に際し、壁パネルの最端部に配置する外装材は、設置場所における調整が必要となるため、施工現場にて設置する。この際、工場にて取り付けられた外装材の端部が仮固定された状態で壁パネルを搬送する場合があり、該外装材を固定する必要があった。
【０００６】
本発明は上記課題を鑑みてなされるものであり、外装材を取り付ける際の表面処理を軽減し、容易に外装材を壁に取り付けることができ、外装材の艤装化を図ることができる外装材取付構造および外装材取付方法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】
上記課題に対し、請求項１の発明は、例えば、図１および図２に示すように、壁体（例えば、壁パネル２等）の外面２ａに外装材１を複数並べ、かつ、隣り合う外装材１を上実部１０と下実部１１とによる実矧ぎによって接合して取り付けてなる外装材取付構造であって、前記外装材１の一方の端部１０ａには、上実部１０と、この上実部１０の下側において側方に開口する溝部１２が形成されており、前記外装材１の他方の端部１１ａには、下実部１１が形成されており、前記壁体（例えば、壁パネル２等）の外面２ａには、外装材１を取り付けるための取付部材３が所定間隔で複数固定されており、前記取付部材３は、前記下実部１１に係止する下実係止部３１が形成され、かつ、壁体（例えば、壁パネル２等）の外面２ａに固定される第１取付部材３ａと、前記溝部１２に係止する溝係止部３２が形成された第２取付部材３ｂとから構成されており、前記第２取付部材３ｂは第１取付部材３ａに係合しており、隣り合う外装材１のうち、一方の外装材１の下実部１１には前記下実係止部３１が係止され、他方の外装材１の溝部１２には前記溝係止部３２が係止されており、
前記第２取付部材３ｂには、前記第２取付部材３ｂを、その溝係止部３２が前記溝部１２から外れる方向に引き込むための爪部３８ａが形成されていることを特徴としている。
【０００８】
請求項１の発明によれば、外装材１の一方の端部１０ａに形成された上実部１０と、この上実部１０の下側において側方に開口する溝部１２と、外装材１の他方の端部１１ａに形成された下実部１１とにより、実矧ぎによって外装材１，１どうしを接合して取り付けることができる。また、壁体の外面２ａには、取付部材３が所定間隔で複数固定されており、一方の外装材１の下実部１１に第１取付部材３ａに備えられた下実係止部３１が係止され、他方の外装材１の溝部１２に第２取付部材３ｂに備えられた溝係止部３２が係止されているので、取付部材３を介して外装材１が壁体に確実に固定されるとともに、隣り合う外装材１，１どうしが容易に接合される。これにより、壁体の外面２ａに外装材１を確実かつ容易に取り付けられるとともに、接合部や取り付け部位が外面に露出せず美しく仕上げることができる。
また、第２取付部材３ｂには、第２取付部材３ｂを、その溝係止部３２が溝部１２から外れる方向に引き込むための爪部３８ａが形成されているので、爪部３８ａを引いて第２取付部材３ｂの溝係止部３２が溝部１２から外れる方向に、第２取付部材３ｂを容易に移動させることができる。
【０００９】
外装材１は、建物の躯体の表面を覆う部材であり、例えば、防火性等を有する板状の素材を用いる場合があり、タイル貼り状やレンガ積み状の模様等、意匠性を高める模様が形成されている。
【００１０】
請求項２の発明は、例えば、図１および図２に示すように、請求項１記載の外装材取付構造において、
前記第１取付部材３ａが壁体（例えば、壁パネル２等）の外面２ａに固定される固定面には、前記第１取付部材３ａを壁体（例えば、壁パネル２等）の外面２ａに固定する止着材（例えば、ビス１００）が挿通される止着孔３６，…を備え、
前記止着孔３６，…は、前記第２取付部材３ｂの溝係止部３２の幅方向における両端部より内側の位置に形成されていることを特徴としている。
【００１１】
請求項２の発明によれば、第１取付部材３ａが壁体の外面２ａに固定される固定面３７に備えられた止着孔３６，…は、第２取付部材３ｂの溝係止部３２の幅方向における両端部より内側の位置に形成されているので、止着孔３６の上方は、第２取付部材３ｂの溝係止部３２が配置されるスペースとなり、平面視において、取付部材３の止着孔３６の上方が妨げられるものがない。したがって、止着孔３６を固定面３７の端部側に設けても、止着材を容易に挿通することができる。これにより、取付部材３の取り付け位置の調整が行い易く、また、壁体端部等にも取付部材３を取り付けることができる。
【００１２】
請求項３の発明は、例えば、図１および図２に示すように、請求項１または２記載の外装材取付構造において、
前記第２取付部材３ｂには、前記壁体（例えば、壁パネル２等）の外面２ａに当接する壁面当接部３５ａから前記外装材１の裏面１ｂに当接するようにして凸部３９が形成されていることを特徴としている。
【００１３】
請求項３の発明によれば、第２取付部材３ｂには、壁体の外面２ａに当接する壁面当接部３５ａから外装材１の裏面１ｂに当接するようにして凸部３９が形成されているので、外装材１の裏面１ｂを安定的に支持することができ、溝係止部３２が溝部１２に係止した状態を維持することができる。
【００１６】
請求項４記載の発明は、例えば、図７〜図１０に示すように、請求項１〜３のいずれか一項に記載の外装材取付構造において、前記取付部材には、前記第１取付部材３００ａと前記第２取付部材とが互いに係合した際の衝撃を緩衝する緩衝材が設けられていることを特徴とする。
【００１７】
なお、前記緩衝材４０とは、第１取付部材３００ａと第２取付部材３００ｂとが係合した際に互いに当接する部位間に設けられる構成が挙げられる。その際、第１取付部材３００ａ及び第２取付部材３００ｂのいずれか一方に取り付けられても良く、両者の当接部分の当接面にそれぞれ取りつけて構成してもよい。また、緩衝材４０としては弾性を有する衝撃吸収材が好ましく、例えばスポンジ等が挙げられる。
【００１８】
請求項４記載の発明によれば、第１取付部材３００ａと第２取付部材３００ｂとが係合した際に、前記緩衝材４０によりその衝撃が干渉され、前記第１取付部材３００ａと第２取付部材３００ｂとが係合した際に係合音などが発生することがない。これにより、前記第１取付部材３００ａと第２取付部材３００ｂとが係合することで両者が摩耗することがなく。取付部材３００自体の耐久力の向上を図ることができる。
【００１９】
請求項５の発明は、例えば、図６に示すように、請求項１〜４のいずれか記載の外装材取付構造において、前記壁体の外面２ａに複数並べられた外装材１のうち最も端に配置された外装材１の自由端としての端部１ａには、上実部１０と、この上実部１０の下側において側方に開口する溝部１２が形成されており、この端部１ａは、前記壁体（例えば壁パネルなど）２の外面２ａに固定された端部第１取付部材（例えば第１取付部材３ａ）と、この端部第１取付部材３ａに係合した状態で前記溝部１２に係止する溝係止部３２が形成された端部第２取付部材（例えば第２取付部材３ｂ）とから構成される端部取付部材（例えば取付部材３）により前記壁体２の外面２ａに取り付けられ、前記端部取付部材３には、前記端部第１取付部材３ａと、前記端部第２取付部材３ｂとが係合した状態を維持する係合維持治具５が嵌合されていることを特徴とする。
【００２０】
請求項５の発明によれば、端部取付部材３には、端部第２取付部材３ｂと、端部第１取付部材３ａとが係合した状態を維持する係合維持治具５が嵌合されているので、端部第２取付部材３ｂが端部第１取付部材３ａに係合した状態を維持することができる。すなわち、端部第２取付部材３ｂを端部第１取付部材３ａに係合して、端部第１取付部材３ａを外装材１の端部１０ａに当接させるとともに端部第２取付部材３ｂの溝係止部３２を外装材１の端部１０ａにある溝部１２に係止した状態で、端部取付部材３が係合維持治具５により嵌合されて、下実部１１が形成された側の外装材１が取り付けられない場合であっても、端部第２取付部材３ｂの溝係止部３２が溝部１２に係止した状態を保つことができる。
【００２１】
請求項６の発明は、例えば、図５および図６に示すように、請求項５記載の外装材取付構造において、前記端部第１取付部材３ａには、上方に配置される外装材１の裏面１ｂと当接して該外装材１を支持する支持部３３が形成されており、前記係合維持治具５は、前記端部第２取付部材３ｂと、前記支持部３３との間に嵌め込まれていることを特徴としている。
【００２２】
請求項６の発明によれば、端部第１取付部材３ａには、上方に配置される外装材１の裏面１ｂと当接して外装材１を支持する支持部３３が形成されているので、第１取付部材３ａの上方に配置される外装材１を安定的に支持することができる。さらに、係合維持治具５は、端部第２取付部材３ｂと、支持部３３との間に嵌め込まれているので、端部第２取付部材３ｂの溝係止部３２が、外装材１の溝部１２と係止した状態で端部第２取付部材３ｂが維持される。したがって、端部第２取付部材３ｂを、その溝係止部３２が溝部１２から外れる方向に動くことを防ぎ、下実部１１が形成された外装材１が係止されていない状態でも、溝部１２が係止された外装材１が壁体から外れることを防ぐ。
【００２３】
請求項７記載の発明は、請求項１〜４のいずれか一項に記載の外装材取付構造において、例えば、図７〜図１０に示すように、前記第２取付部材３００ｂは、前記第１取付部材３００ａに対して移動することで、前記第１取付部材３００ａに対する係合状態が解除され且つ前記溝係止部３２が前記外装材１Ａの溝部１２との係止状態が解除されるように設けられ、前記取付部材３００には、前記第２取付部材３００ｂの溝係止部３２が前記外装材１Ａの溝部１２に係止した状態で保持する係止状態保持手段（例えば、突出片３０８、切欠部３１０）と、前記溝係止部３２が前記外装材１Ａの溝部１２から外れ前記係止状態が解除された状態で保持する解除状態保持手段（例えば突出片３０８、切欠部３０９）とが設けられていることを特徴とする。
【００２４】
ここで前記係止状態保持手段としては、例えば、第１取付部材及び第２取付部材のそれぞれに、両者が係合して第２取付部材の溝係止部３２が外装材１Ａの溝部１２に係止した状態のときに互いに係合する係合部及び被係合部を設けた構成などが挙げられる。
また、前記解除状態保持手段としては、例えば、第２取付部材３００ｂを第１取付部材３００ａに対してスライド移動させるなどのように移動させて、両者の係合状態が解除されるとともに、前記外装材１Ａの溝部１２から前記溝係止部３２が離間して溝部１２と溝係止部３２との係合状態が解除されるように構成し、その状態で、互いに係合する係合部と被係合部とを第１取付部材及び第２取付部材のそれぞれに設けた構成とすることが挙げられる。上記構成の場合、係止状態保持手段及び解除状態保持手段のそれぞれの係合部あるいは被係合部を同一のものとしてもよい。例えば、第１取付部材３００ａ及び第２取付部材３００ｂのいずれか一方に突出片を設け、他方に、第２取付部材の移動により溝部と溝係止部とが係合する状態及び解除された状態とで前記突出片とそれぞれ係合する２つの切欠溝を設けた構成等が挙げられる。
【００２５】
請求項７記載の発明によれば、前記取付部材３００の備える係止状態保持手段３０８，３１０により、前記第２取付部材３００ｂの溝係止部３２が前記外装材１Ａの溝部１２に係止した状態で保持することができるとともに、前記解除状態保持手段３０８，３０９により前記溝係止部３２が前記外装材１Ａの溝部１２から外れ前記係止状態が解除された状態で保持することができる。つまり、前記係止状態保持手段３０８，３１０及び解除状態保持手段３０８，３０９によって前記溝係止部３２が溝部１２に係止した状態及び係止解除状態とにそれぞれ保持できることにより、前記溝部１２を備える外装材に隣接して外装材が配置されていない場合、例えば前記取付部材を介して壁面に取りつけられた外装材に隣接して次の外装材を並べて取りつける際に、前記第２取付部材３００ｂの溝係止部３２を先に配置された外装材の溝部１２に係止させた状態で保持することで前記先に配置された外装材を壁面から外れないようにして取りつけることができる。そして、その状態のまま次の外装材を隣接して配置して取りつけることができる。
【００２６】
請求項８の発明は、例えば、図４に示すように、請求項１〜７のいずれか一項に記載の外装材取付構造を施工する際に、壁体（例えば、壁パネル２等）の外面２ａに外装材１を取り付ける外装材取付方法であって、壁体（例えば、壁パネル２等）の外面２ａに、隣り合う外装材１，１どうしを上実部１０と下実部１１とによる実矧ぎによって接合して取り付けるに際し、まず、取付部材３の第２取付部材３ｂを第１取付部材３ａに係合して、第１取付部材３ａを壁体（例えば、壁パネル２等）の外面２ａに固定するとともに、この第１取付部材３ａを一方の外装材１の一方の端部１０ａに当接し、次いで、第２取付部材３ｂの溝係止部３２を一方の外装材１の溝部１２に係止し、かつ、他方の外装材１の下実部１１を一方の外装材１の上実部１０の下側に挿入するとともに、第１取付部材３ａの下実係止部３１を前記下実部１１に係止することを特徴としている。
【００２７】
請求項８の発明によれば、壁体の外面２ａに、隣り合う外装材１，１どうしを実矧ぎによって接合して取り付けるに際し、まず、取付部材３の第２取付部材３ｂを第１取付部材３ａに係合して、第１取付部材３ａを壁体の外面２ａに固定するとともに、この第１取付部材３ａを一方の外装材１の一方の端部１０ａに当接するので、第１取付部材３ａによって、外装材１の一方の端部１０ａの取り付ける位置を誘導することができる。次いで、第２取付部材３ｂの溝係止部３２を一方の外装材１の溝部１２に係止し、かつ、他方の外装材１の下実部１１を一方の外装材１の上実部１０の下側に挿入するとともに、第１取付部材３ａの下実係止部３１を下実部１１に係止するので、隣り合う外装材１，１どうしが確実に接合されるとともに、壁体に効率よく取り付けることができる。さらに、外装材１，１どうしの接合部分において、上実部１０によって下実部１１の上側が覆われるので、第１取付部材３ａの下実係止部３１が露出することがなく、外観を美しく仕上げることができる。
【００２８】
【発明の実施の形態】
以下、図面を参照して本発明に係る外装材取付構造について説明する。図１は、本発明にかかる第１の実施の形態における外装材取付構造を用いて、壁面に外装材１を取り付けた状態を示す断面図であり、壁体を形成する壁パネル２と、この壁パネル２の表面を覆う外装材１と、外装材１を取り付ける取付部材３と、この取付部材３を壁パネル２に取り付けるビス（止着材）１００とによって、外装材取付構造の主要部が構成されている。
壁パネル（壁体）２は、図１１に示すように、縦框材２０１，２０１と横框材２０２，２０２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２０３，…が縦横に組まれて枠体２０４が形成され、さらにこの枠体２０４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２０４の表裏面に合板等の面材２０５，２０５が貼設されたものである。また、図４に示すように、面材２０５，２０５の外面２ａには胴縁４…が水平方向に所定の間隔で設けられている。なお、本例では、壁パネル２に、工場にて透湿防水シート（図示せず）を貼設後、胴縁４を貼設している。
【００２９】
このような艤装パネルは、基準寸法＝９１０ｍｍを１Ｍ（モジュール）として、例えば、１／８Ｍ、１／４Ｍ、１／２Ｍ、１Ｍ、２Ｍ、４Ｍ…の寸法に規格化された標準パネルを主として構成されている。
【００３０】
胴縁４は長尺な合板であり、壁パネル２に上下に所定間隔で複数本設けられている。この胴縁４によって壁パネル２と外装材１との間に空間Ｓが形成され、外壁内部の通気性や防音性を高める効果を奏する。
【００３１】
外装材１は、壁パネル２との間に胴縁４や取付部材３によって所定間隔を保ちながら壁パネル２の表面を覆う部材であり、防火性等を有する板状の素材を用いる場合があり、例えば、タイル貼り状やレンガ積み状の模様等、意匠性を高める模様が形成されている。
【００３２】
取付部材３は、図３に示すように、２つの部材から構成されている。すなわち、胴縁４に取り付けることにより壁パネル２の外面２ａに固定する第１取付部材３ａと、この第１取付部材３ａに係合して取り付ける第２取付部材３ｂとから構成されている。
【００３３】
第１取付部材３ａは、胴縁４の上面４ａの幅と等しい幅を有する固定面３７が形成されている。固定面３７の幅方向の両辺には、それぞれ上方に垂直に突出して支持部３３および下実係止部３１が形成されている。支持部３３は固定面３７よりやや上方に水平面３３ａを形成するように外側に曲折して形成されている。
【００３４】
一方、この支持部３３と対向する辺には、第１取付部材３ａの幅とほぼ等しい幅を有する側壁部３１ａが、壁面当接部３５ａに連続して形成されている。この側壁部３１ａの両端の上部が、延出して支持部３３，３３側に曲折して、上方に傾斜する下実係止部３１，３１が形成されている。
【００３５】
なお、固定面３７の中央部にはビス１００や釘等を挿通させる止着孔３６が所定間隔で３箇所に形成されている。さらに、この止着孔３６，…の両脇には、平行して隆起するリブ３７ａ，３７ａを備えており、固定面３７の強度を補強している。
【００３６】
さらに、側壁部３１ａの基端部側の曲折部３１ｂ近傍に設けられた止着孔３６の両端には、略四方形に切欠して挿通孔３４が形成されている。この挿通孔３４は、固定面３７だけでなく、曲折部３１ｂにおいて、側壁部３１ａの下部も切欠している。
【００３７】
第２取付部材３ｂは、図３に示すように、溝係止部３２と、側壁部３２ａと、支持部３３と、挿入部３５と、延出部３８とにより主要部が構成されている。第２取付部材３ｂは、平板状の側壁部３２ａが立設されており、その上端部に、上方に傾斜して該側壁部３２ａの一方の面側に曲折する溝係止部３２が形成されている。この側壁部３２ａは、溝係止部３２が曲折している側の面の下部から二の挿入部３５，３５が延出し、該側壁部３２ａの反対側の面の両端下部より水平方向に延出する延出部３８，３８が形成されており、この挿入部３５，３５と延出部３８，３８とによって側壁部３２ａは支持されている。
【００３８】
なお、延出部３８，３８は、第２取付部材３ｂの幅方向の両端に形成されており、その先端部は上方に曲折して爪部３８ａ，３８ａを形成している。この爪部３８ａ，３８ａは、第２取付部材３ｂが第１取付部材３ａに係合した状態を解く際に、該爪部３８ａ，３８ａを引手として用いることにより、第２取付部材３ｂを係合した方向から容易に引き出すことができる。
【００３９】
また、挿入部３５，３５は、延出部３８，３８より内側に設けられ、挿入部３５，３５どうしが離間して形成されている。この挿入部３５，３５の幅は第１取付部材３ａの挿通孔３４，３４の幅よりやや短く設定されている。さらに、挿入部３５，３５は胴縁４の上面４ａに当接する平面な板状の壁面当接部３５ａ，３５ａを形成し、該壁面当接部３５ａ，３５ａの端部には断面コ字状の凸部３９，３９を形成している。凸部３９，３９は、水平面を形成する上面部３９ａ，３９ａと、この上面部３９ａ，３９ａから下方に向けて垂直に曲折して凸状に形成されており、上面部３９ａ，３９ａは、外装材１が取り付けられた状態で外装材１の裏面１ｂと当接する位置に設定されている。
【００４０】
第１取付部材３ａと、第２取付部材３ｂとが係合した状態においては、両端に下実係止部３１，３１が配置され、この下実係止部３１，３１の間に溝係止部３２が位置している。
【００４１】
続いて、取付部材３を用いた外装材取付構造について説明する。まず、図１に示すように、取付部材３は、第１取付部材３ａの挿通孔３４に、第２取付部材３ｂの挿入部３５が挿通されており、第１取付部材３ａの側壁部３１ａと第２取付部材３ｂの側壁部３２ａとが当接する位置まで進入して係合している。この状態で、第１取付部材３ａの固定面３７が上方から胴縁４に当接し、かつビス１００が所望の位置の止着孔３６より胴縁４および壁パネル２側に挿通され、ねじ込まれることにより、第１取付部材３ａが固定されている。
【００４２】
第２取付部材３ｂの溝係止部３２は、外装材１の溝部１２に係止され、かつ、外装材１の裏面１ｂは第２取付部材３ｂの凸部３９，３９の上面３９ａ，３９ａに当接することにより、溝部１２を備えた外装材１の端部１０ａが安定的に係止されている。さらに、第１取付部材３ａの上方には外装材１の下実部１１を備える端部１１ａが載置され、この外装材１の裏面１ｂが第１取付部材３ａの支持部３３の上面３３ａと当接している。そして、下実部１１の先端面（端部１１ａの先端面）は、第２取付部材３ｂの側壁部３２ａと当接し、第１取付部材３ａの下実係止部３１が該下実部１１の傾斜部上面１１ｂに係止されている。すなわち、第１取付部材３ａと第２取付部材３ｂとが係合する際に当接する側壁部３１ａ，３２ａは、外装材１の溝部１２下方の側端面１２ａと、隣接する外装材１の下実部１１の端部１１ａとの間に挟むようにして配置されている。また、隣り合う外装材１，１どうしは、上実部１０の先端側の下面１０ｃと下実部１１の上面１１ｃとが当接して接着剤５５にて接着されている。
【００４３】
続いて、係合維持治具５について説明する。図５および図６に示すように、係合維持治具５は、符号５１に示す平板部と、符号５２に示す嵌合部と、符号５３に示す係止部とにより主要部が構成されている。平板部５１は、平面視矩形に形成され、この平板部５１の裏面に、板状の嵌合部５２を備えている。なお、平板部５１は透過性を有するプラスチックで形成されており、係合状態が見えるようになっている。
【００４４】
嵌合部５２は、第１取付部材（端部第１取付部材）３ａの固定面３７の面積にほぼ等しい面積を有しており、第２取付部材（端部第２取付部材）３ｂが第１取付部材（端部第１取付部材）３ａに係合している状態を維持するために、嵌め込まれるものである。なお、嵌合部５２の厚さは、第１取付部材（端部第１取付部材）３ａの支持部３３の上面部３３ａとリブ３７ａ，３７ａの頂部との高さの差とほぼ等しくなるように設定されている。したがって、該嵌合部５２が第２取付部材３ｂと支持部３３との間に嵌め込まれた状態において、嵌合部５２の下面がリブ３７ａ，３７ａの頂部と当接し、平板部５１の裏面と、第１取付部材（端部第１取付部材）３ａの支持部３３上面とがほぼ面一となり、係合維持治具５が安定して嵌め込まれる。
【００４５】
係止部５３は、第１取付部材（端部第１取付部材）３ａの支持部３３を係止するものであり、断面略Ｌ字状に形成されており、平板部５１の裏面に取り付けられて、溝部５３ａ，５３ａが支持部３３の位置に対応するようにして２箇所に形成されている。この係止部５３，５３どうしの間隔は、第１取付部材（端部第１取付部材）３ａの支持部３３の幅とほぼ等しくなるように設定されている。また、この溝部５３ａ，５３ａの下面５３ｃ，５３ｃの厚さは、第１取付部材（端部第１取付部材）３ａの支持部３３の上面３３ａの高さより薄くなるように設定されている。
【００４６】
次に、係合維持治具５の取付構造について説明する。
図６に示す係合維持治具５は、壁パネル２の外面２ａに複数並べられた外装材１，１のうち最も端に配置された外装材１の自由端としての端部１ａを壁パネル２の外面２ａに取りつける端部取付部材（ここでは取付部材３と同様の構成）に嵌合されている。
そして、係合維持治具５は、取付部材３に嵌合することで、該取付部材３の備える、壁体の外面２ａに固定された端部第１取付部材（例えば第１取付部材３ａ）と、この端部第１取付部材３ａに係合した状態で溝部１２に係止する溝係止部３２が形成された端部第２取付部材（例えば第２取付部材３ｂ）とが係合した状態を維持している。
【００４７】
つまり、図６では、第１取付部材（端部第１取付部材）３ａの上部には外装材１が載置されない場合、第２取付部材（端部第２取付部材）３ｂおよび第１取付部材（端部第１取付部材）３ａの側壁部３１ａ，３２ａどうしが当接するように係合した状態で、係合維持治具５の嵌合部５２が、第１取付部材３ａの固定面３７の上方に位置し、かつ、溝部５３ａの開口部に支持部３３が係合している。すると、嵌合部５２が、第２取付部材（端部第２取付部材）３ｂの側壁部３２ａと第１取付部材（端部第１取付部材）３ａの支持部３３との間に嵌合するとともに、第１取付部材（端部第１取付部材）３ａの支持部３３，３３が係止部５３，５３によって係止されている。また、取付部材３に係合維持治具５が取り付けられた状態において、嵌合部５２の下面は第１取付部材（端部第１取付部材）３ａのリブ３７ａの頂部に当接し、係止部５３，５３の下面５３ｃが胴縁４の上面４ａに当接している。
【００４８】
次に、本実施の形態における外装材取付方法について説明する。まず、図３に示すように、壁パネル２の外側表面に水平方向に所定間隔で設けられた胴縁４…に取付部材３を、外装材１の幅に応じて、上下の位置を整列させて取り付ける。すなわち、第２取付部材３ｂを第１取付部材３ａに係合させた状態で、第１取付部材３ａの固定面３７を胴縁４…に当接させ、ビス１００を止着孔３６から胴縁４側に挿通して、ビス打ち機（図示せず）にてビス１００（止着材）をねじ込んで固定する。このとき、第１取付部材３ａを取り付ける位置に応じて、複数の止着孔３６，…の中から所望の止着孔３６を選択する。
【００４９】
次に、図３に示すように、壁パネル２の端部から、外装材１を順次取り付ける。外装材１の取り付け手順を図４を用いて説明する。まず、（６ａ）に示すように、第１の外装材１の下実部１１を、第１取付部材３ａの下実係止部３１に係止するとともに、溝部１２を備えた側の端部１０ａを該第１取付部材３ａに隣接する第２の取付部材３の第２取付部材３ｂの凸部３９に載置する。この際、外装材１の溝部１２下方の側端面１２ａが取付部材３の第１取付部材３ａの側壁部３１ａに当接している。
【００５０】
続いて、（６ｂ）および（６ｃ）に示すように、隣接して設ける第２の外装材１を、第２取付部材３ｂの側壁部３２ａを押すようにして、第１の外装材１の上実部１０より下方に押し込む。この際、第２の外装材１の下実部１１の上面１１ｃには接着剤５５が付けられている。
【００５１】
第２取付部材３ｂの側壁部３２ａが、第１取付部材３ａの側壁部３１ａに当接する位置まで、第２の外装材１の下実部１１を押し込んだら、（６ｄ）に示すように、第２の外装材１の裏面１ｂが第１取付部材３ａの支持部３３と当接するように配置され、第２取付部材３ｂの溝係止部３２が、第１の外装材１の溝部１２に係止する。これにより、第１の外装材１の上実部１０に、第２の外装材１の下実部１１が覆われて、この下実部１１の上面１１ｃに付けていた接着剤５５により隣接する外装材１，１の端部どうしが接合される。この（６ａ）〜（６ｄ）の行程を繰り返しながら、順次外装材１，…を壁パネル２の前面に取り付けてゆき、壁パネル２の他方の端部まで外装材１，…を取り付ける。
【００５２】
ところで、図６に示すように、壁パネル２の端部のように、工場で取り付け可能な外装材１のうち端部に配置される外装材１を取り付ける取付部材３の第１取付部材３ａの上部には外装材１が載置されない。このとき、第２取付部材３ｂは、外装材１の溝部１２との係止を解く方向（矢印Ａ）に動く可能性がある。そこで、第２取付部材３ｂおよび第１取付部材３ａの側壁部３１ａ，３２ａどうしが当接するように係合した状態で、係合維持治具５の嵌合部５２を、第１取付部材３ａの固定面３７の上方に位置し、かつ、係止部５３，５３どうしの隙間Ｓに一方の支持部３３が位置するように配置する。そして、溝部５３ａの開口部に支持部３３が係合するように、該係合維持治具５を横方向に移動させる。すると、嵌合部５２が、第２取付部材３ｂの側壁部３２ａと第１取付部材３ａの支持部３３との間に嵌合し、第２取付部材３ｂが、第１取付部材３ａに係合された状態が維持される。さらに、第１取付部材３ａの支持部３３，３３が係止部５３，５３によって係止されているので、取付部材３と係合維持治具５とが係合した状態となる。
【００５３】
本実施の形態の例における外装材取付構造によれば、隣り合う外装材１，１を接合して取り付ける際、第１取付部材３ａによって、一方の外装材１の下実部１１を備えた端部を固定し、第２取付部材３ｂによって、他方の外装材１の溝部１２を備えた端部を固定できる。したがって、取付部材３を介して、隣接する外装材１，１どうしを容易かつ確実に取り付けることができる。
【００５４】
さらに、上実部１０によって外装材１，１どうしの接合部分が覆われるので、溝係止部３２および下実係止部３１が、外壁の表面に露出することがなく、外観を美しく仕上げることができ、外装材１の表面側から、釘等の止着材を打ち込んで取り付ける場合のように、露出した止着材を隠す処理を行う手間が軽減される。また、第２取付部材３ｂを胴縁４に固定し、該第２取付部材３ｂを第１取付部材３ａに係合するので、壁パネル２には第２取付部材３ｂを止着する必要がなく、取付部材３を止着する作業を軽減できる。
【００５５】
また、第１取付部材３ａの固定面３７には止着孔３６，…が、第２取付部材３ｂの溝係止部３２の幅方向の両端より内側に設けられているので、止着孔３６，…が固定面３７側に曲折している下実係止部３１を避けて形成されることとなる。したがって、止着孔３６を固定面３７に形成可能な場所が広がり、固定面３７の下実係止部３１が形成された側の端部近傍にも止着孔３６を形成することができ、ビス打ち機の先端や金槌等により、止着材のねじ込みまたは打ち込みが可能となる。これにより、ビス１００をねじ込む位置が壁パネル２のモジュールの端部になってしまう箇所でも、複数の止着孔３６を使い分けてビス１００をねじ込むことで、芯材が設けられている位置に取付部材３を取り付けることができ、作業の利便性が高まる。
【００５６】
さらに、係合維持治具５を用いるので、端部に配置される外装材１の溝部１２を係止する第２取付部材３ｂの溝係止部３２が、係止が外れる方向に移動することを防ぐことができる。したがって、壁パネル２に外装材１を取り付ける作業を工場で行い搬送する際に、第２取付部材３ｂが溝部１２との係止が解かれることを防ぎ、外装材１が取り付けられた壁パネル２を容易に搬送できる。
【００５７】
本実施の形態の例における外装材取付方法によれば、より簡易な方法で、容易かつ確実に外装材を取り付けることができる。
【００５８】
図７〜図１０に本発明に係る第２の実施の形態における外装材の取付構造を示す。
図７に示す外装材の取付構造は、壁体を構成する壁パネル２及び胴縁４、壁パネル２の表面を覆う外装材１、外装材１を取り付ける取付部材３００、取付部材３００を壁パネル２に取り付けるビス（止着材）１００等で、主要部が構成され、上述した第１の実施の形態と比べて、取付部材３００の構成のみ異なり、その他の構成は略同様の構成となっている。よって以下では同一の構成要素には同符号、同名称を用いて説明は省略する。
【００５９】
すなわち、本実施の形態の外装材の取付構造では、壁パネル２の外面２ａに上述した外装材と同様の外装材１を複数並べ、かつ、隣り合う外装材１を上実部１０と下実部１１とによる実矧ぎによって接合して取り付けてなり、これら外装材１は、壁パネル２の外面２ａに胴縁４を介して複数固定された取付部材３００を介して取り付けられている。
【００６０】
外装材１の一方の端部１０ａには、上実部１０と、この上実部１０の下側において側方に開口する溝部１２が形成されており、外装材１の他方の端部１１ａには、下実部１１が形成されている。
【００６１】
取付部材３００は、図８に示すように、上述の取付部材３と同様に２つの部材から構成され、胴縁４に取り付けることにより壁パネル２の外面２ａに固定された第１取付部材３００ａと、この第１取付部材３００ａに該第１取付部３００ａに対してスライド移動可能に係合して取り付けられた第２取付部材３００ｂ等とを備える。そして、この取付部材３００では、第２取付部材３００ｂは第１取付部材３００ａに対して移動することで、第１取付部材３００ａに対する係合状態が解除され且つ当該第２取付部材３００ｂの溝係止部３２が外装材１Ａの溝部１２との係止状態が解除可能に形成されている。
さらに、この取付部材３００には、第２取付部材３００ｂの溝係止部３２が外装材１Ａの溝部１２に係止した状態で保持する係止状態保持手段（突出片３０８、切欠部３１０）と、溝係止部３２が外装材１Ａの溝部１２から外れ係止状態が解除された状態で保持する解除状態保持手段（突出片３０８、切欠部３０９）とが設けられている。
【００６２】
第１取付部材３００ａには、並べて配置され隣り合う外装材のうち一方の外装材１の下実部１１に係止する下実係止部３０１が形成（図７参照）され、第２取付部材３００ｂには、前記一方の外装材１と並べて配置された他方の外装材１Ａの溝部１２に係止可能する溝係止部３２が形成（図７参照）されている。
【００６３】
第１取付部材３００ａは、胴縁４の上面４ａの幅と等しい幅を有し、胴縁４の表面に当接した状態で固定される固定面３０７を備える。この固定面３０７は平面視略矩形状に形成されてなり、その幅方向の両辺のうち、一方の辺には曲折部３１ｂで折曲されて垂直上方に立ち上がる側壁部３１ａが設けられている。
この側壁部３１ａは、第１取付部材３００ａの幅とほぼ等しい幅を有し、この側壁部３１ａの上部の両端部には、他方の辺側に向かって斜めに突出する下実係止部３１，３１が形成されている。
【００６４】
下実係止部３１の側壁部３１ａに対する傾斜は、該下実係止部３１が係止する一方の外装材１の下実部１１の先端面と該先端面に連続する傾斜部上面１１ｂとが形成する角度に対応したものとなっている。
また、側壁部３１ａの内面には、第２取付部材３００ｂの側壁部２３ａが当接する緩衝材４０が取り付けられている。
【００６５】
また、他方の辺には、固定面３０７よりやや上方で下実係止部３１よりも低い位置に配置され、一方の外装材１の裏面に当接する水平な上面３３ａを有する支持部３３が形成されている。
支持部３３は他方の辺から鉛直に立ち上がり、側壁部３１ａと対向するとともに固定面３０７の幅と略等しい幅の立ち上がり部を有し、この立ち上がり部の先端の両端に、第１取付部材３０ａの幅方向の両端部から外側、つまり固定面３０７と逆側に曲折して上面３３ａが突設されている。
この支持部３３は、上面３３ａ上に、下実係止部３１に係止された下実部１１を有する一方の外装材１が載置されることで外装材１を支持している。
【００６６】
なお、固定面３０７の中央部には、ビス１００や釘等を挿通させる止着孔３６が所定間隔で固定面３０７の幅方向と直交する方向に、つまり外装材１を並べる方向に３箇所並べて形成されている。さらに、この止着孔３６，…の両脇には、平行して隆起するリブ３７ａ，３７ａを備えており、固定面３０７の強度を補強している。
【００６７】
さらに、固定面３０７には、リブ３７ａの外方に当該固定面３０７の上面から鉛直上方に突出され、第２取付部材３００ｂの切欠部３０９，３１０と係合する突出片３０８が形成されている。これら係止片３０８及び切欠部３０９，３１０等とから係止状態保持手段及び解除状態保持手段を構成している。
【００６８】
また、固定面３０７において、側壁部３１ａの基端部側の曲折部３１ｂ近傍に設けられた止着孔３６の両端部分には、略四方形に切欠して挿通孔３４が形成されている。この挿通孔３４は、固定面３０７だけでなく、曲折部３１ｂにおいて、側壁部３１ａの下部も切欠している。
【００６９】
第２取付部材３００ｂは、図７及び図８に示すように、第１取付部材３０ａの外方で他方の外装材１Ａの溝部１２に係止された溝係止部３２と、第１取付部３０ａの側壁部３１ａの内側で緩衝材４０に密着された側壁部３２ａと、側壁部３２ａの下端から互いに離間する方向に延出された挿入部３５及び延出部３８Ａ等とにより主要部が構成されている。なお、この第２取付部材３００ｂは、延出部３８Ａを備える点以外の構成は上述した第２取付部材３０ｂの構成と略同様のものである。
したがって、第２取付部材３００ｂにおいて第２取付部材３０ｂの構成と同様の構成には同名称、同符号を付して説明は省略する。
【００７０】
すなわち、第２取付部材３００ｂの備える側壁部３２ａは、第１取付部材３０ａの固定面３０７上で略垂直に配置された平板状のものであり、この上端部に溝係止部３２が、上方に傾斜して該側壁部３２ａの一方の面側、つまり、第１取付部３０ａの側壁部３１ａ側に曲折し、該側壁部３１ａから外方に突出して設けられている。また、この側壁部３２ａは第２取付部材３００ｂ自体の移動により第１取付部材３００ａの側壁部３１ａに対して対向した状態で離間する方向に移動可能となっている。
【００７１】
また、挿入部３５，３５は、側壁部３２ａの下部の中央部分から溝係止部３２が曲折している側に、互いに離間して並んで延出されているとともに、第１取付部３０ａの挿入孔３４に挿入されている。
挿入部３５，３５の幅は第１取付部材３００ａの挿通孔３４，３４の幅よりやや短く設定され、側壁部３２ａから延出された胴縁４の上面４ａに当接する平面な板状の壁面当接部３５ａ，３５ａと、該壁面当接部３５ａ，３５ａの端部に設けられ、上方に突出する断面コ字状の凸部３９，３９とを有する。
【００７２】
凸部３９，３９は、水平面を形成する上面部３９ａ，３９ａと、この上面部３９ａ，３９ａの両端部から下方に向けて垂直に曲折して凸状に形成されており、上面部３９ａ，３９ａは、外装材１が取り付けられた状態で外装材１の裏面１ｂと当接する位置に設定されている（図７参照）。
つまり、図７では、挿入部３５は、側壁部３１ａに隣接した状態で下面が胴差４に当接し、その先端部の凸部３９の上面が他方の外装材１Ａの裏面に当接しており、外装材１Ａを胴差４の上面から所定間隔開けた状態で支持している。
【００７３】
延出部３８Ａ，３８Ａは、側壁部３２ａの下部の両端から挿入部３５，３５の外方で、挿入部３５，３５の延出方向と逆方向に、略水平方向に延出して設けられ、第１取付部３０ａの固定面３０７上に、固定面３０７の内方、つまり第１取付部材３１ａから離間する方向にスライド移動可能に載置されている。つまり、この延出部３８Ａ，３８Ａは、第２取付部材３００ｂの幅方向の両端に形成されており、挿入部３５，３５とによって側壁部３２ａを支持している。
【００７４】
また、延出部３８Ａ，３８Ａでは、図９及び図１０に示すように、側壁部３２ａから延在し且つ互いに対向する辺部が、固定面３０７の突出片３０８に隣接し、これら辺部は、第２取付部材３００ｂの移動に伴い、第１取付部材３００ａの固定面３０７の突出片３０８に沿って摺動可能に形成されており、さらに、この辺部には、所定位置を切り欠くことで、突出片３０８が係合する切欠部３０９，３１０が形成されている。
【００７５】
切欠部３０９，３１０は、前記辺部の基端部側と先端部側とに２カ所形成されている。図７では、先端部側の切欠部３１０に突出片３０８が係合され、溝係止部３２が第１取付部材３００ａの側壁部３１ａから外方に突出して他方の外装材１Ａの溝部１２に係止された状態を保持している。このときの取付部材３００の状態を図９に示す。
【００７６】
さらに、延出部３８Ａの先端部には、上方に曲折してなる爪部３８ａ，３８ａが形成されている。この爪部３８ａ，３８ａは、第２取付部材３００ｂが係合する第１取付部材３００ａの側壁部３１ａから離間する方向、つまり、支持部３３側に引くことで、先端部側の切欠部３１０が係止片３０８から外れて、第２取付部材３００ｂの側壁部３２ａが第１取付部材３００ａから離間する方向に移動する。これにより他方の外装材１Ａの溝部１２に係止する溝係止部３２が、第１取付部材３００ａの側壁部３１ａが当該側壁部３１ａから外方に突出した状態から第１取付部材３００ａの内方、つまり側壁部３１ａから没する方向に移動する。そして、延出部３８Ａの基端部側の切欠部３０９が突出片３０８に係合することで、第２取付部材３００ｂの溝係止部３２は、側壁部３１ａの内側、つまり固定面３０７上方に配置される（図１０参照）。つまり、爪部３８ａ，３８ａを引手として用いることにより、第２取付部材３００ｂを係合した方向から容易に引き出すことができる。
【００７７】
また、この爪部３８ａを第１取付部材３００ａの側壁部３１ａ側に押圧することで、切欠部３０９から突出片３０８が外れて、第２取付部材３００ｂの側壁部３２ａ及び延出部３８Ａは、第１取付部材の固定面３７上を第１取付部材３００ａの側壁部３１ａ側に移動する（図７及び図９参照）。
そして、側壁部３２ａは側壁部３１ａの緩衝材４０に当接するとともに溝係止部３２が側壁部３１ａの外方に突出し、さらに切欠部３１０が突出片３０８に係合することで、溝係止部３２が側壁部３１ａの外方に突出した状態が保持されるものである。
【００７８】
続いて、取付部材３００を用いた外装材取付構造について説明する。まず、図７に示すように、取付部材３００は、第１取付部材３００ａの挿通孔３４に、第２取付部材３００ｂの挿入部３５が挿通されており、第１取付部材３００ａの側壁部３１ａの緩衝材４０と第２取付部材３００ｂの側壁部３２ａとが当接する位置まで進入して係合している。この状態で、第１取付部材３００ａの固定面３０７が上方から胴縁４に当接し、かつビス１００が所望の位置の止着孔３６より胴縁４および壁パネル２側に挿通され、ねじ込まれることにより、第１取付部材３００ａが固定されている。
【００７９】
第２取付部材３００ｂの溝係止部３２は、外装材１の溝部１２に係止され、かつ、外装材１の裏面１ｂは第２取付部材３００ｂの凸部３９，３９の上面３９ａ，３９ａに当接することにより、溝部１２を備えた外装材１の端部１０ａが安定的に係止されている。さらに、第１取付部材３００ａの上方には外装材１の下実部１１を備える端部１１ａが載置され、この外装材１の裏面１ｂが第１取付部材３００ａの支持部３３の上面３３ａと当接している。そして、下実部１１の先端面は、緩衝材４０を介して側壁部３１ａに密着している第２取付部材３００ｂの側壁部３２ａに密着しているとともに、第１取付部材３００ａの下実係止部３１が該下実部１１の傾斜部上面１１ｂに係止されている。すなわち、第１取付部材３００ａと第２取付部材３００ｂとが係合する際に緩衝材４０を介して密着する側壁部３１ａ，３２ａは、外装材１の溝部１２下方の側端面１２ａと、隣接する外装材１の端部１１ａとの間に挟むようにして配置されている。また、隣り合う外装材１，１どうしは、上実部１０の先端側の下面と下実部１１の上面とが当接して接着剤５５にて接着されている。
【００８０】
上記第２の実施の形態における外装材の取付構造によれば、上述した第１の実施の形態における外装材の取付構造と略同様の作用効果を得ることができるとともに、第１取付部材３００ａの側壁部３１ａと第２取付部材３００ｂの側壁部３２ａとが係合、つまり当接する際に、側壁部３１ａに設けられた緩衝材４０を介して係合することになり、緩衝材４０によりその衝撃が干渉され、第１取付部材３００ａの側壁部３１ａと第２取付部材３００ｂの側壁部３２ａとが係合した際に、互いにぶつかることなく係合音が発生することがない。これにより、第１取付部材３００ａと第２取付部材３００ｂとが係合することでその衝撃により両者が摩耗することがなく、取付部材３００自体の耐久力の向上を図ることができる。
【００８１】
特に、第１取付部材３００ａ及び第２取付部材３ｂとをそれぞれ金属製からなるものとした場合、具体的には鋼製板材により形成した場合、互いに当接する部分に緩衝材４０が介在していることから、このように構成された取付部材３００を介して壁体に外装材を取り付けた後、風等で外壁に外力が加わった場合でも、金属製の第１取付部材３００ａ及び第２取付部材３ｂどうしが直接接触することがなく、外装材が取りつけられた壁内部から金属どうしの接触音が聞こえることがない。
【００８２】
さらに、取付部材３００の備える係止状態保持手段としての突出片３０８及び延出部３８Ａの切欠部３１０により、第２取付部材３００ｂの溝係止部３２が外装材１Ａの溝部１２に係止した状態を保持することができるとともに、解除状態保持手段としての突出片３０８及び切欠部３０９により溝係止部３２が外装材１Ａの溝部１２から外れ、係止状態が解除された状態で保持することができる。
【００８３】
よって、溝部１２を備える外装材１Ａに隣接して外装材１が配置されていない場合、例えば取付部材３００を介して壁面２ａに取りつけられた外装材１Ａに隣接して次の外装材１を並べて取りつける場合等において、第２取付部材３００ｂの溝係止部３２を先に配置された外装材１Ａの溝部１２に係止させた状態で保持することで先に配置された外装材１Ａを壁面から外れないようにすることができる。そして、その状態のまま、次の外装材１を隣接配置して、互いの上実部１０及び下実部１１を前記取付部材３００を介して実矧ぎして取りつけることができる。つまり、先に取りつけた外装材１が外れることなく、次の外装材の取り付け作業を容易に行うことができる。
【００８４】
なお、本実施の形態の例における外装材取付構造によれば、壁体を壁パネル２としたが、これに限定するものではなく、従来の工法によって形成される壁体であってもよく、要は壁体の外面に外装材を取り付け可能な構成であればよく、作業の利便性に応じて適宜選択すればよい。
【００８５】
また、本実施の形態では、止着材をビス１００としたが、これに限定するものではなく、例えば、釘等であってもよく、要は取付部材３を壁パネル２に固定可能なものであればよい。さらに、上記各実施の形態における取付部材３、３００のそれぞれを構成する第１取付部材３ａ、３００ａ及び第２取付部材３ｂ、３００ｂは、鋼板を折曲、切り欠き等の加工を施すことで形成している。よって、多種の素材を用いることなく、取付部材３，３００を容易に製作でき、その製作コストの低廉化、製作作業性の向上を図ることができる。
