【０００１】
【発明の属する技術分野】
この発明は、建物の壁体に外装材を取り付けるための外装材の取付金具および外装材の縦貼り用胴縁、並びに、建物の壁体に外装材を取り付ける外装材の取付け工法に関する。
【０００２】
【背景の技術】
近年、住宅等の建物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、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が知られている。
【０００３】
図１１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。上記縦框材１０１，１０１と横框材１０２，１０２とは面材１０５，１０５の間に介設される芯材の１つを構成するものである。
【０００４】
従来、上記のような壁パネルへ外装材を取り付けるには、例えば、外壁用のものでは、前記面材１０５，１０５に胴縁を取り付け、その上に外装材をネジ又は釘等で止着する。胴縁が介在することで壁パネルと外装材との間に空間が設けられ、この間に結露が溜まってしまうなどの不具合が回避される。
【０００５】
また、取付金具により壁パネルへ外装材を取り付ける方法も従来公知であり、例えば、特開平１０−３０６５０９号に開示されている。
取付金具を用いた外装材の取付方法としては、例えば、図１２に示すような取付方法がある。
この方法は、例えば、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。
【０００６】
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ことが出来るようになっている。
【０００７】
この取付金具を用いた外装材の取付け方法によれば、釘打ちにより外装材を取り付けてしまう従来の方法に較べて外装材の取り付けを容易にすることか出来ると共に、取付金具により外装材と外壁１１０との間に空間が設けられるので、胴縁を不要とすることが出来る。
【０００８】
【発明が解決しようとする課題】
しかしながら、上記のような取付金具を介した外装材の取付け方法を、外装材を縦貼りする場合（縦に長く設置する場合）に適用する場合、次のような課題を生じさせた。
すなわち、外装材を縦貼りする場合、取付金具は外装材の左右の縁部に対応して縦方向に多数配置されている必要があり、且つ、取付金具は強度確保のため壁パネルの芯材の箇所に止着される必要がある。これら両者の条件を満たすには、取付金具は壁パネルの横芯材でなく縦芯材の箇所に止着する必要がある。なぜなら、横芯材に取付金具を止着したのでは、縦方向に並ぶ取付金具の数が横芯材の数に限られてしまい数が少なくなるからである。
【０００９】
更に、取付金具を縦芯材に止着する場合、次のような問題を生じさせた。すなわち、取付金具の横方向の間隔が壁パネルの縦芯材の間隔に限定されるので、外装材の横幅長もこの間隔により限られてしまう。また、壁パネルに対する外装材の割付け位置がずれてしまうと、取付金具の止着位置が壁パネルの縦芯材の箇所からずれてしまい、外装材を取り付けられないといった問題を生じさせた。
【００１０】
ところで、上記従来の取付金具を用いた外装材の取付け方法は、外装材を直接釘等により止着するのに較べて外装材の取付けが容易になっているものの、現場にて取付金具を壁パネルに止着していく工程が付加される分まだ煩雑であり、作業工程の改善の余地は残されている。
【００１１】
この発明は、上記実状に鑑みてなされたもので、取付金具を用いて外装材を縦貼りする場合でも、取付金具の横方向の取付け間隔や外装材の横幅長に制約が掛けられることなく、確実な強度で且つ容易に外装材を壁体に取り付けることの出来る外装材の取付金具、外装材の縦貼り用胴縁、および、外装材の取付け工法を提供することを目的としている。
【００１２】
【課題を解決するための手段】
次の手段の説明中、括弧書きにより実施の形態に対応する構成を１例として例示する。実施の形態と同一の単語を使用している場合には符号のみ記す。上記課題を解決するため、請求項１記載の発明は、図３と図４に示すように、建物の壁体（２０）に外装材（４０）を取り付けるための外装材の取付金具（１）であって、ベース枠（２）の正面側に、左右の外装材（４０，４０）の各縁部に設けられた被係合部（４１，４２）にそれぞれ係合する外装材係合部（係合片７ａ，７ａ，７ｂ）が設けられる一方、前記ベース枠（２）の裏面側に、壁体（２０）と外装材（４０，４０）との間に介在され左右方向に伸びる胴縁（横胴縁３０）に取り付けられる胴縁用取付け部（案内部３Ａ，３Ｂ、接触面４ａ〜４ｃ）が設けられており、
前記胴縁用取付け部には、胴縁（横胴縁３０）の取付け面に沿って広がると共に、胴縁（横胴縁３０）への取付け時に前記取付け面に面接触される接触面（４ａ〜４ｃ）が前記ベース枠（２）の左右両端側と中央側にそれぞれ設けられており、前記中央側の接触面（４ｂ）に止着用孔（５ａ）が形成されており、
前記左右方向に伸びる胴縁（横胴縁３０）の縦幅より広い幅長を有すると共に、前記胴縁用取付け部には、胴縁（横胴縁３０）が嵌入されて案内される凹状の案内部（３Ａ，３Ｂ）が設けられている構成とした。
【００１３】
この請求項１記載の発明によれば、取付金具（１）が胴縁（横胴縁３０）に取り付けられた状態で外装材（４０）が壁体（２０）に取り付けられる構成を実現するので、例えば、予め胴縁（横胴縁３０）に取付金具（１）を止着しておき、その後、この胴縁（横胴縁３０）を壁体（２０）に固定すると云った方法が可能となり、それにより、従来、取付金具（１）を１個ずつ壁体（２０）に固定していたのに較べて、作業効率が向上する。
また、取付金具（１）が胴縁（横胴縁３０）に取り付けられた状態で胴縁（横胴縁３０）が壁体（２０）に固定される構成を実現するので、胴縁（横胴縁３０）が壁体（２０）に高い強度で接続できれば取付金具（１）が高強度に固定されることとなり、個々の取付金具（１）を従来のように壁体（２０）の高強度に接続できる箇所（例えば芯材（２３，縦框材２４）のある箇所など）に対応させて取り付ける必要がなくなる。それゆえ、外装材（４０）を縦張りする場合でも、取付金具（１）の横並びの間隔や外装材（４０）の横幅の長さを壁体（２０）に関係なく自由に選択することが出来る。
また、取付金具（１）の左右方向の位置を自由に設定できることから、壁体（２０）に対する外装材（４０）の割り付け位置も自由に設定できると共に、壁体（２０）に対して外装材（４０）の割り付け位置がずれた場合でも、問題なく外装材（４０）を取り付けることが出来る。
【００１４】
ここで、上記の外装材係合部は、外装材の縁部に設けられた被係合部をただ掛け止めするタイプ、金属弾性を利用し外装材を取付金具に押し付けることで外装材の被係合部を係止し固定するタイプ、取付金具を分離固定可能な２つの部材で構成すると共にこれら２つの部材で外装材の被係合部を挟みつけることで該被係合部を固定するタイプなど、種々の形式がありえる。
また、取付金具はそれのみで外装材を固定可能なタイプに限られず、外装材の仮止めや半固定をするタイプのものも含まれる。仮止めや半固定した場合には、後に釘やネジで外装材の本固定を行う。
また、上記の胴縁用取付け部は、例えば、釘やネジで木製の胴縁に取り付けられるタイプ、接続片を有しネジ等で金属製の胴縁に取り付けられるタイプ、溶接等で金属製の胴縁に取り付けられるタイプなど、胴縁取付け用のものであれば種々の形式が含まれる。
【００１６】
また、胴縁（横胴縁３０）が凹状の案内部（３Ａ，３Ｂ）に嵌入されて案内されるので、取付金具（１）を胴縁（横胴縁３０）へ固定する際の作業性が向上される。すなわち、正確な位置・傾きで容易に且つ確実に取付金具（１）を胴縁（横胴縁３０）に固定することが出来る。
【００１８】
また、取付金具（１）の接触面（４ａ〜４ｃ）が胴縁（横胴縁３０）の取付け面に面接触することで、取付金具（１）を安定した状態で胴縁（横胴縁３０）に固定することが出来る。また、取付金具（１）を強固に止着しても取付金具（１）が胴縁（横胴縁３０）に食い込んでしまうと云った不都合が回避される。なお、この接触面（４ａ〜４ｃ）に貫通した止着部（止着用孔５ａ）を設け、該止着部を介して釘やネジによる胴縁（横胴縁３０）への止着を行うことで、より安定した固定を行うことが出来る。
【００１９】
請求項２に記載の発明は、前記ベース枠（２）の中央部には開口部（６）が設けられ、前記中央側の接触面（４ｂ）が前記開口部（６）に臨んで設けられており、前記開口部（６）の側縁に凹部（６ａ）が設けられている構成とした。
請求項３記載の発明は、建物の壁体（２０）と外装材（４０）との間に長手方向を横にして介在される横胴縁（３０）に、前記請求項１または２に記載の外装材（４０）の取付金具（１）が、所定間隔を開けて複数個取り付けられていることを特徴とする外装材（４０）の縦貼り用横胴縁とした。
【００２０】
この請求項３記載の発明によれば、壁体（２０）に上記横胴縁（３０）を取り付けた後、横胴縁（３０）に付いた取付金具（１）を介して外装材（４０）を組み付けるだけで外装材（４０）の壁体（２０）への取り付けを遂行することが出来る。すなわち、壁体（２０）の周りに足場を組んで壁体（２０）に１個ずつ取付金具（１）を取り付けていくと云った従来の煩雑な作業が省け、現場における作業効率を大幅に向上することが出来る。また、取付金具（１）は１本１本独立した横胴縁（３０）に対して固着されることでこの縦貼り用横胴縁（３０）が構成されるので、壁体（２０）の周りに足場を組んで取付金具（１）を１個ずつ壁体（２０）に取り付けていくのに較べて、取付金具（１）が容易に且つ正確に横胴縁（３０）に固定される。従って、正確で確実な外装材（４０）の取り付けが可能となる。また、横胴縁（３０）を壁体（２０）に取り付けることで取付金具（１）が固定されるので、従来、取付金具（１）を個々に壁体（２０）に取り付けていた場合にあった、取付金具（１）の取付位置や横方向の取付間隔並びに外装材（４０）の横幅長の制約が生じない。従って、取付金具（１）の取付間隔や外装材（４０）の横幅長を自由に設定して外装材（４０）を取り付けることが出来る。
【００２１】
請求項４記載の発明は、建物の壁体（２０）に外装材（４０）を取り付ける外装材（４０）の取付け工法において、予め工場にて請求項１または２に記載の外装材（４０）の取付金具（１）を横胴縁（３０）に所定間隔を開けて複数個設ける工場艤装工程と、外装材（４０）を取り付ける現場にて、前記取付金具（１）が取り付けられた横胴縁（３０）をその長手方向を横にして前記壁体（２０）の芯材（２３，縦框材２４）に止着する横胴縁止着工程と、横胴縁（３０）が止着された壁体（２０）に前記取付金具（１）を介して外装材（４０）を縦が長くなる方向に組み付ける外装材組付け工程とを有する工法とした。
【００２２】
この請求項４記載の発明によれば、工場艤装により高い生産性および高い信頼性で取付金具（１）を横胴縁（３０）に設けることが出来ると共に、外装材（４０）の取付け現場では壁体（２０）への横胴縁（３０）の取付けと、取付金具（１）を介した外装材（４０）の組み付けのみ行えばよいので、現場での作業工程が大幅に縮小される。また、取付金具（１）の設けられた横胴縁（３０）を使用して外装材（４０）を取り付けるので、外装材（４０）を縦貼りする場合でも、取付金具（１）の取付位置や横方向の取付間隔並びに外装材（４０）の横幅長の制約が生じず、取付金具（１）の取付間隔や外装材（４０）の横幅長を自由に設定して外装材（４０）を取り付けることが出来る。
【００２３】
【発明の実施の形態】
以下、この発明の実施の形態の外装材４０の取付金具１、縦貼り用胴縁、および、取付工法について、図１〜図６の図面を参照しながら説明する。
図１〜図３は、本発明の実施の形態の取付金具１を示すもので、図１（ａ）はその正面図、図１（ｂ）は下面図、図２（ａ）は左側面図、図２（ｂ）は右側面図、図３は斜視図である。
この実施の形態の取付金具１は、建物（例えば住宅）の壁体２０に外装材４０を取り付けるための金具で（図４参照）、アルミやステンレス等の金属をプレス加工や折曲加工等により一体成形して構成される。この取付金具１は、正面視でほぼ矩形状のベース枠２に、外装材係合部としての係合片７ａ，７ｂ、横胴縁３０に取り付けられる胴縁用取付け部である凹状の案内部３Ａ，３Ｂおよび接触面４ａ〜４ｃ、並びに、横胴縁３０に取り付けるための止着用孔（止着部）５ａ，５ｂが設けられている。
【００２４】
ベース枠２は、横胴縁３０の取付け面における短い方の幅よりも広い幅長を有し、また、外装材４０と壁体２０との間に空間を設けるために厚み方向に嵩を有している。また、ベース枠２の上面部は外装材４０に当接される当接面２ａ，２ｂになっている。
案内部３Ａ，３Ｂ（図２，図３）は、ベース枠２の左右の立脚部にそれぞれ設けられた、横胴縁３０が嵌入される凹状の開口である。案内部３Ａ，３Ｂの深さは横胴縁３０の厚さと同じ長さに設けられ、案内部３Ａ，３Ｂに横胴縁３０を嵌入した際に横胴縁３０の裏面とベース枠２の裏側の端部が面一になるように設計されている。
【００２５】
接触面４ａ〜４ｃは、横胴縁３０の正面側の面（取付面）に面接触することで、取付金具１を横胴縁３０に対して安定的に据えさせるためのものである。これら３つの接触面４ａ〜４ｃは同一の高さに設けられ、２個の接触面４ａ，４ｃはベース枠２の左右両端側に、１個の接触面４ｂはベース枠２の中央側、中央の開口部６に臨んで設けられている。止着用孔（止着部）５ａ，５ｂは、取付金具１を横胴縁３０にネジ又は釘により止着するためのものであり、一方の止着用孔５ｂは仮止め用のものでベース枠２に設けられ、他方の止着用孔５ａは本止め用のもので中央の接触面４ｂに設けられている。
【００２６】
係合片７ａ，７ｂ，７ａは、外装材４０の左右の縁部に設けられた被係合部４１，４２と係合する片であり、これら被係合部４１，４２が挿入される空間を設ける立脚部７ｃからほぼ直角（９０度より僅かに小さい角度）に折り曲げられた形状に形成されている。これら係合片７ａ…，７ｃは、立脚部７ｃを含めて金属弾性により僅かに変移可能に構成され、この弾性を利用して外装材４０が挿入されるようになっている。
なお、上記の係合片７ａ，７ａ，７ｃなど、取付金具１の前面に設けられる係合部の構成は、外装材４０の被係合部の構成や外装材４０の組付け方法等に対応して種々に変更可能である。
【００２７】
次いで、本発明の縦貼り用胴縁の実施の形態について説明する。
縦貼り用胴縁は、上記の取付金具１を複数所定間隔を開けて横胴縁３０に固定したユニットである。取付金具１…の固定位置は、外装材４０…の割付け位置に対応して設定される。
なお、上記の取付金具１を横胴縁３０に取り付ける工程は、例えば、現場でなく工場にて行い、現場では一体的に構成された縦貼り用胴縁を使用することが、品質管理や作業工程の短縮化からみて好ましい。
【００２８】
次に、上記取付金具１…を用いて外装材４０…を建物の壁体２０に取り付ける本発明の実施の形態の外装材の取付工法について説明する。
図４は、取付金具を介して外装材を壁体に取り付ける工程を示す斜視図である。
【００２９】
この実施の形態の外装材の取付工法は、予め工場にて上述した取付金具１…を横胴縁３０…に所定間隔を開けて複数個設ける工場艤装工程、外装材４０…を取り付ける現場にて上記横胴縁３０…をその長手方向を横にして壁体２０に止着する胴縁止着工程、並びに、横胴縁３０…が止着された壁体２０に取付金具１…を介して外装材４０を縦が長くなる方向に組み付ける外装材組付け工程等を含んでなる。
上記工場艤装工程は、横胴縁３０…に複数の取付金具１…をネジ又は釘等の止着部材により所定位置に止着する工程である。ここで、取付金具１…の止着位置は、壁体２０に対する外装材４０…の割り付けに対応させて設定する。
【００３０】
胴縁止着工程は、工場艤装された取付金具１…付きの横胴縁３０を、壁体２０の芯材２３…又は縦框材２４…の箇所に、ネジ又は釘にて止着していく工程である。ここで、壁体２０には、例えば、縦框材２４…、横框材、縦芯材２３および横芯材からなる骨組に面材２１，２２を貼り合わせた壁パネルを用いている。また、横胴縁３０…は縦方向に横芯材の数より多い多数段止着し、それぞれの横胴縁３０…の横方向の取付け位置は、上下段の横胴縁３０…に取り付けられた取付金具１…が縦に一直線に揃うように止着する。このとき、取付金具１…が壁体２０の芯材２３…や縦框材２４…の箇所にくる必要はない。
なお、壁体２０として壁パネルを用いて説明したが、本発明の外装材の取付工法は、壁体として、例えば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壁体にも適用可能である。
【００３１】
図５は、取付金具と外装材との係合部の周辺を示す横断面図である。図６は、外装材の下端部の周辺を示す縦断面図である。
外装材組付け工程は、取付金具１…の係合片７ａ，７ａ，７ｂや外装材４０…の被係合部４１，４２の構成に応じて適宜変更可能な工程であり、ここではその一例を説明する。
この外装材組付け工程が開始される前に、基礎７２上の土台７１に外装材４０を支持すると共に外装材４０裏の水抜きをする水抜き用桟５０（図４，図６参照）を取付け枠５３を介して例えば十字穴付き木ネジ５４等で止着しておく。図６中、符号５２が水抜き用の穴である。
【００３２】
外装材４０の組み付けは、取付金具１…の係合片７ａ，７ａ，７ｂの弾性を利用して、縦２列に並ぶ複数の取付金具１…の間に外装材４０を押し入れていくことで行う。詳細には、図５を参照しながら説明するが、先ず、外装材４０の右側の被係合部４２のみを縦１列に並ぶ取付金具１…の係合片７ａ，７ａに掛け止め（係合）させる。次いで、左側の被係合部４１を左の１列の取付金具１…に押し入れて被係合部４１を係合片７ｂに係合させる。このとき、バールなどにより取付金具１…の係合片７ｂを立たせる方向に圧し、更に、外装材４０の僅かな反りを利用して被係合部４１の係止ブロック４１ａを係合片７ｂのサイドを通過させて、係合片７ｂを被係合部４１の凹部４１ｂに通す。
なお、この被係合部４１の係止ブロック４１ａを係合片７ｂのサイドを通過させる際、取付金具１の上面開口部６およびその側縁に設けられた凹部６ａが、被係合部４１に当節しないように逃げ、これによりスムーズに被係合部４１を取付金具１に係合ざせることが出来る。
【００３３】
或いは、外装材４０の左縁部の構成において、被係合部４１の係止ブロック４１ａ（図５）を取付金具１…に対応する高さ範囲のみに設ける一方、取付金具１の無い範囲の係止ブロック４１ａを削除しておくことで、更に、容易に外装材４０の組付けが可能となる。
すなわち、外装材４０の左縁部を嵌める際に、外装材４０を高さ方向に少しずらし取付金具１…に対応する高さに係止ブロック４１ａが削除された範囲を持ってくる。そして、そのまま、外装材４０の左縁部を取付金具１…に押し入れる（係止ブロック４１ａが無いのですんなり入る）。そして、その後、外装材４０を降下させることで取付金具１…の係合片７ｂが被係合部４１の凹部４１ｂに挿入されて係合される。
【００３４】
ここで、下から１段目の外装材４０は、図６に示すように、その下端部が水抜き用桟５０の支持部５１に当節されて支持される。また、下から２段目以降の外装材４０は１段下の外装材４０の上端部に当節して支持される。
そして、隣接する複数の外装材４０が組み付いたら、左右の外装材４０が重なっている被係合部４１，４２の中間の範囲にスペーサー４４を噛ませて外装材４０…のがたを無くす。更に、隣接する複数の外装材４０…の連結部分にシーリング加工をして外装材４０…の組付けを完了する。
【００３５】
以上のように、この実施の形態の外装材４０の取付金具１、横胴縁３０に取付金具１…を取り付けたユニットである外装材の縦貼り用胴縁、並びに、外装材４０…の取付工法によれば、取付金具１…が横胴縁３０に取り付けられた状態で外装材４０…が壁体２０に取り付けられる構成を実現するので、例えば、予め横胴縁３０…に取付金具１…を止着しておき、その後、この横胴縁３０を壁体２０に固定すると云った方法が可能となり、従来１個ずつ取付金具を壁体２０に固定していたのに較べて作業効率が著しく向上する。
また、取付金具１…は横胴縁３０を介して壁体２０に固定される構成を実現するので、横胴縁３０が壁体２０に高い強度で接続できれば取付金具１…も壁体２０に対して高強度に固定される。それゆえ、従来の取付金具１…の取付位置が壁体２０の縦芯材２３…や縦框材２４…の位置に限られると云った制約が取り除かれ、取付金具１…の横並びの間隔や外装材４０…の横幅の長さを壁体２０に関係なく自由に選択することが出来る。
また、取付金具１…の左右方向の取付位置を自由に設定できることから、壁体２０に対する外装材４０…の割付け位置も自由に設定できると共に、壁体２０に対して外装材４０…の割付け位置がずれた場合でも、従来と異なり問題なく外装材４０…を取り付けることが出来る。
【００３６】
また、この実施の形態の取付金具１によれば、横胴縁３０を嵌入して案内する凹状の案内部３Ａ，３Ｂが設けられていることから、取付金具１を横胴縁３０に固定する際の作業性が向上され、更に、正確な位置・傾きで容易に且つ確実に取付金具１を横胴縁３０に固定することが出来る。
また、取付金具１には横胴縁３０の取付け面に面接触する接触面４ａ〜４ｃが設けられていることから、取付金具１を安定した状態で横胴縁３０に固定することが出来る。
【００３７】
また、この実施の形態の外装材の取付工法によれば、工場艤装により高い生産性および高い信頼性で取付金具１…を横胴縁３０に設けることが出来ると共に、外装材４０…の取付け現場では壁体２０への横胴縁３０の取付けと、取付金具１…を介した外装材４０…の組み付けのみ行えばよいので、現場での作業工程が大幅に縮小される。
【００３８】
なお、本発明は、この実施の形態の外装材の取付金具１、縦貼り用胴縁、取付工法に限られるものでなく、例えば、取付金具に設けられる外装材係合部は、外装材の縁部に設けられた被係合部を掛け止めするタイプの他、取付金具を分離固定可能な２つの部材で構成すると共にこれら２つの部材で外装材の被係合部を挟みつけることで該被係合部を固定するタイプなど、種々の形式がありえる。また、取付金具はそれのみで外装材を固定可能なタイプに限られず、外装材の仮止めや半固定をするタイプのものも含まれる。仮止めや半固定した場合には、後に釘やネジで外装材の本固定を行う。その他、取付金具や縦貼り用胴縁の構成、外装材の取付工法の各工程など、この実施の形態で具体的に述べた細部構造および方法は、発明の主旨を逸脱しない範囲で適宜変更可能である。
【００３９】
【発明の効果】
請求項１および２記載の外装材の取付金具によれば、取付金具が胴縁に取り付けられた状態で外装材が壁体に取り付けられる構成を実現する。従って、例えば、予め胴縁に取付金具を止着しておき、その後、この胴縁を壁体に固定すると云った方法が可能となり、従来に較べて作業効率が著しく向上する。また、取付金具が胴縁に取り付けられた状態で胴縁が壁体に固定される構成を実現するので、胴縁が壁体に高い強度で接続できれば取付金具も壁体に対して高強度に固定される。それゆえ、従来のように取付金具の取付位置が芯材の位置に限られると云った制約が取り除かれ、取付金具の横並びの間隔や外装材の横幅の長さを壁体に関係なく自由に選択することが出来る。また、取付金具の左右方向の取付位置を自由に設定できることから、壁体に対する外装材の割り付け位置も自由に設定できると共に、壁体に対して外装材の割り付け位置がずれた場合でも、問題なく外装材を取り付けることが出来る。
【００４０】
また、胴縁を嵌入する凹状の案内部が設けられていることから、取付金具を胴縁へ固定する際の作業性が向上される。更に、正確な位置・傾きで容易に且つ確実に取付金具を胴縁に固定することが出来る。
【００４１】

BACKGROUND OF THE INVENTION
The present invention relates to a mounting bracket for an exterior material for attaching an exterior material to a wall of a building and a longitudinal edge of the exterior material, and an attachment method for the exterior material for attaching the exterior material to the wall of the building.
[0002]
[Background technology]
In recent years, the construction of buildings such as houses has been industrialized. For example, components such as walls, floors, and roofs are panelized in the factory in advance, and these panels are assembled at the construction site to construct the building. Panel construction method is adopted in part.
As a panel used for such a panel construction method, for example, a wall panel as shown in FIG. 11 is known.
[0003]
The wall panel 100 shown in FIG. 11 has a vertical frame member 101, 101 and a horizontal frame member 102, 102 assembled in a rectangular shape, and a reinforcing core member 103 is assembled in the vertical and horizontal directions 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). . The vertical saddle members 101 and 101 and the horizontal saddle members 102 and 102 constitute one of the core members interposed between the face members 105 and 105.
[0004]
Conventionally, in order to attach the exterior material to the wall panel as described above, for example, for the exterior wall, a body edge is attached to the face materials 105 and 105, and the exterior material is fastened to the exterior material with screws or nails. . By interposing the trunk edge, a space is provided between the wall panel and the exterior material, and troubles such as accumulation of condensation are avoided during this time.
[0005]
A method of attaching an exterior material to a wall panel using a mounting bracket is also known in the art, and is disclosed, for example, in JP-A-10-306509.
As an attachment method of the exterior material using the attachment bracket, for example, there is an attachment method as shown in FIG.
In this method, for example, a long longitudinal joiner 111 is attached to the outer surface of the outer wall 110 at a predetermined interval, and then the exterior material 112 is attached by laterally sticking from the bottom to the top. At this time, the mounting bracket 113 is attached at a predetermined interval. The exterior material 112 is attached in such a manner.
[0006]
For example, the mounting bracket 113 is formed by punching and bending an iron plate, and includes a lower engagement portion (not shown) that engages with an end surface portion of the lower exterior material 112, and an end surface of the upper exterior material 112. And an upper engaging portion (not shown) for engaging and supporting the 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 can be attached to the upper end of the wall.
[0007]
According to the mounting method of the exterior material using the mounting bracket, it is possible to facilitate the mounting of the exterior material as compared with the conventional method of mounting the exterior material by nailing, and the exterior material and the outer wall by the mounting bracket. Since a space is provided between 110 and 110, a trunk edge can be made unnecessary.
[0008]
[Problems to be solved by the invention]
However, when the exterior material mounting method via the mounting bracket as described above is applied to the case where the exterior material is vertically attached (when the exterior material is installed long vertically), the following problems are caused.
That is, when the exterior material is attached vertically, a large number of mounting brackets must be arranged in the vertical direction corresponding to the left and right edges of the exterior material, and the mounting brackets are the core material of the wall panel to ensure strength. It is necessary to be fixed to the part of. In order to satisfy both of these conditions, the mounting bracket needs to be fixed to the vertical core member instead of the horizontal core member of the wall panel. This is because if the mounting bracket is fixed to the horizontal core member, the number of mounting brackets arranged in the vertical direction is limited to the number of horizontal core members, and the number is reduced.
[0009]
Further, when the mounting bracket is fixed to the vertical core member, the following problems are caused. That is, since the interval in the horizontal direction of the mounting bracket is limited to the interval between the vertical core members of the wall panel, the lateral width of the exterior material is also limited by this interval. Further, when the position of the exterior material to the wall panel is shifted, the fixing position of the mounting bracket is shifted from the position of the vertical core member of the wall panel, and the exterior material cannot be attached.
[0010]
By the way, although the mounting method of the exterior material using the above conventional mounting bracket is easier to mount the exterior material than attaching the exterior material directly with a nail or the like, The process of fixing to the panel is still complicated, and there is still room for improvement of the work process.
[0011]
This invention was made in view of the above-mentioned actual situation, and even when the exterior material is vertically attached using the mounting bracket, there is no restriction on the lateral mounting interval of the mounting bracket and the lateral width of the exterior material, An object of the present invention is to provide a mounting bracket for an exterior material that can be easily attached to a wall body with a certain strength, a body edge for vertically attaching the exterior material, and a method for attaching the exterior material.
[0012]

The mounting method of the exterior material of this embodiment is a factory installation process in which a plurality of the mounting brackets 1... Previously described in the factory are provided at predetermined intervals on the lateral trunk edge 30. A body edge fastening process for fastening the horizontal trunk edges 30 to the wall body 20 with the longitudinal direction thereof being transverse, and a wall body 20 to which the horizontal trunk edges 30 are fastened to the wall body 20 via the mounting bracket 1. It includes an exterior material assembling step for assembling the exterior material 40 in a direction in which the longitudinal direction becomes longer.
The factory outfitting step is a step of fixing the plurality of mounting brackets 1 to the horizontal trunk edges 30 at predetermined positions with fixing members such as screws or nails. Here, the fixing positions of the mounting brackets 1 are set in correspondence with the allocation of the exterior materials 40 to the wall body 20.
[0030]
In the body edge fastening process, the factory-fitted horizontal waist edge 30 with the mounting bracket 1 is fastened to the core member 23 of the wall body 20 or the longitudinal member 24 with screws or nails. It is a process to go. Here, as the wall body 20, for example, a wall panel is used in which face members 21 and 22 are bonded to a frame made of the vertical rod member 24, the horizontal rod member, the vertical core member 23, and the horizontal core member. In addition, the horizontal trunk edges 30 are fastened in the vertical direction by a number of steps larger than the number of horizontal cores, and the horizontal mounting positions of the horizontal trunk edges 30 are attached to the horizontal trunk edges 30 of the upper and lower stages. The mounting brackets 1 are fixed so that they are aligned vertically. At this time, it is not necessary for the mounting brackets 1 to come to the places of the core members 23 of the wall body 20 and the vertical rod members 24.

[0031]
FIG. 5 is a cross-sectional view showing the periphery of the engaging portion between the mounting bracket and the exterior material. FIG. 6 is a longitudinal sectional view showing the periphery of the lower end portion of the exterior material.
The exterior material assembling step is a step that can be appropriately changed according to the configuration of the engagement pieces 7a, 7a, 7b of the mounting bracket 1 ... and the engaged portions 41, 42 of the exterior material 40 ..., and here is an example thereof. Will be explained.
Before the exterior material assembling step is started, a drainage bar 50 (see FIGS. 4 and 6) for supporting the exterior material 40 on the base 71 on the foundation 72 and draining the back of the exterior material 40 is used. For example, it is fixed by means of a cross-recessed wood screw 54 or the like via the mounting frame 53. In FIG. 6, reference numeral 52 denotes a hole for draining water.
[0032]
The exterior material 40 is assembled by pushing the exterior material 40 between a plurality of longitudinally arranged mounting brackets 1... Using the elasticity of the engaging pieces 7a, 7a, 7b of the mounting brackets 1. Do. Although details will be described with reference to FIG. 5, first, only the engaged portion 42 on the right side of the exterior member 40 is latched to the engaging pieces 7 a and 7 a of the mounting brackets 1. ) Next, the left engaged portion 41 is pushed into the left row of the mounting brackets 1 to engage the engaged portion 41 with the engaging piece 7b. At this time, a bar or the like is used to press the engagement piece 7b of the mounting bracket 1 in an upright direction, and the engagement block 41a of the engaged portion 41 is further engaged with the engagement piece 7b by using a slight warp of the exterior member 40. The engaging piece 7b is passed through the recessed portion 41b of the engaged portion 41 through the side of the engaging portion 7b.
When the locking block 41a of the engaged portion 41 is passed through the side of the engaging piece 7b, the upper surface opening 6 of the mounting bracket 1 and the concave portion 6a provided on the side edge thereof are connected to the engaged portion 41.

【The invention's effect】
  Claim 1And 2According to the mounting bracket of the exterior material described, a configuration in which the exterior material is mounted on the wall body in a state where the mounting bracket is mounted on the trunk edge is realized. Therefore, for example, it is possible to use a method in which a mounting bracket is fixed to the barrel edge in advance, and then the barrel edge is fixed to the wall body, and the working efficiency is remarkably improved as compared with the prior art. In addition, since the body edge is fixed to the wall body with the mounting bracket attached to the wall edge, if the body edge can be connected to the wall body with high strength, the mounting metal body also has high strength against the wall body. Fixed. Therefore, the restriction that the mounting position of the mounting bracket is limited to the position of the core material as in the prior art is removed, and the horizontal interval of the mounting bracket and the width of the exterior material can be freely set regardless of the wall. You can choose. In addition, since the mounting position of the mounting bracket in the left-right direction can be set freely, the layout position of the exterior material relative to the wall can be set freely, and even if the layout position of the exterior material is shifted relative to the wall, there is no problem. Exterior material can be attached.
[0040]
  AlsoSince the concave guide portion for inserting the trunk edge is provided, workability when fixing the mounting bracket to the trunk edge is improved. Further, the mounting bracket can be fixed to the trunk edge easily and reliably with an accurate position and inclination.
[0041]
  AlsoSince the contact surface that is in surface contact with the mounting surface of the trunk edge is provided, the mounting bracket can be fixed to the trunk edge in a stable state.
[0042]
  Claim3According to the longitudinally-applied body edge of the exterior material described above, after attaching this body edge to the wall body, the exterior material can be attached to the wall body only by assembling the exterior material through a mounting bracket provided on the body edge. Installation can be performed. That is, the work efficiency at the site can be greatly improved as compared with the prior art. In addition, since the mounting brackets are fixed to the independent body edges one by one, the horizontal body edges for vertical attachment are configured, so that it is easier and easier than attaching the mounting hardware directly to the wall. The mounting bracket can be accurately attached to the trunk edge. Moreover, since the mounting bracket is fixed to the wall body by attaching this body edge to the wall body, the restriction that the mounting position of the mounting bracket is limited to the position of the core material as in the prior art is removed, The interval between the mounting brackets and the width of the exterior material can be freely selected regardless of the wall. In addition, the layout position of the exterior material with respect to the wall can be freely set.
[0043]
  Claim4According to the described invention, the mounting bracket can be provided on the horizontal trunk edge with high productivity and high reliability by the factory equipment, and the mounting of the horizontal trunk edge to the wall body and the mounting bracket at the installation site of the exterior material Since it is only necessary to assemble the exterior material through the work, the work process at the site is greatly reduced. In addition, since the exterior material is attached using the horizontal trunk edge provided with the mounting bracket, there are restrictions on the mounting position of the mounting bracket, the horizontal mounting interval, and the lateral width of the exterior material even when the exterior material is vertically attached. It does not occur, and the mounting interval of the mounting bracket, the lateral width of the exterior material, and the allocation of the exterior material to the wall can be freely set.
