【発明の属する技術分野】
本発明は、乾式のサイディング材を躯体に固定すると共に出隅部分に出隅用外壁材を固定して建築物の壁面における出隅を施工するに際し、出隅用外壁材の固定及びこの出隅用外壁材の側方に隣接するサイディング材と前記出隅用外壁材との接続を、効率良くしかも意匠性に優れた状態に施工することができるばかりでなく、補修を行う場合などにサイディング材を痛めることもない建築物の壁面における出隅構造及びその施工方法に関するものである。
【０００２】
【従来の技術】
建築物の壁面を構成するための乾式のサイディング材としては、樋状の金属板の樋内に合成樹脂発泡体が充填されており必要に応じて裏面がアルミニウム箔をラミネートされた紙や金属板等の裏面材により被覆されている金属サイディング材や、セメント，コンクリート等より製作される窯業サイディング材があり、それぞれ所定の長さに形成されているものが利用されている。
【０００３】
このようなサイディング材は、通常長手方向と平行な幅方向両端縁部に、隣接して固定されるサイディング材の幅方向端縁同士を互いに係合する係合部が形成されていて、その一方の係合部には建築物の躯体に釘やビス等で固定される固定部が設けられている。そして、サイディング材をその幅方向に固定するには、先に固定されているサイディング材の一方の係合部に次に固定されるサイディング材の他方の係合部を係合した後、柱，間柱，胴縁や既設の壁面を改修する場合には既設の壁面材上に直接又は既設の壁面材上に新たに固定した胴縁等の躯体にタッピンビス等の固定具により固定する作業を順次繰返し行うのである。
【０００４】
また、このようなサイディング材を使用して横張り施工される壁面における出隅部分を施工するには、サイディング材の長手方向であって出隅部分側の端縁を隣合う壁面の成す角度の１／２の角度に形成せしめておいてこの端縁同士を突き合わせたり、一方のサイディング材の端縁部を他方のサイディング材の端縁に臨ませて端縁部同士を突き合わせたりした状態に配置固定すると、外観が悪いばかりでなく、突き合わせた部分から雨水が侵入してサイディング材が金属サイディング材の場合には金属板や合成樹脂発泡体に腐食する現象が発生したり、更にはサイディング材等の寸法誤差により突き合わせ部分に隙間が発生したりするので、サイディング材が金属サイディング材であっても窯業サイディング材であっても、出隅部分で隣接するサイディング材の端縁部同士間には端縁を隠蔽する連結材が使用されている。
【０００５】
この連結材としては、金属板を折曲することによって隣接する各壁面側に向けてサイディング材の端縁を挿入される保持部がそれぞれ形成されているもの、例えば図６及び図７に示す如く略中央が隣接する壁面の成す角度で裏面側に折曲されて出隅部分の頂部3c'を成しており、この頂部3c'からそれぞれ両側に所定の距離だけ離れた位置で裏面側に１８０度の角度で折り返されて後に表面側に９０度の角度で折曲され更に表面側に９０度の角度で折曲されてサイディング材１の長手方向の端縁部1aが挿入される保持部3b'が形成されていると共にその端縁を前記１８０度の角度で折り返した線より外方に突出されて躯体７に釘やタッピンビス８によって固定される固定部3a'が形成されている金属板製の長尺状の連結材３'を例示することができる。
【０００６】
このような従来の連結材３'を使用して上記した如きサイディング材１を横張り固定して出隅部分を構成する方法について簡単に説明する。
先ず、図６及び図７に示す如く出隅部分の躯体７に予め連結材３'の固定部3a'を釘やタッピンビス等の固定具８により固定する。
そして、通常、施工すべき壁面の下部にサイディング材１の長手方向を水平にしてその長手方向端縁部1aを保持部3b'内に挿入し、このサイディング材１の一方の幅方向端縁部（通常、上側の幅方向端縁部）1bに延設されている固定部を釘やタッピンビス等の固定具により躯体７に固定し、この既固定のサイディング材１の上方に次に固定するサイディング材１の長手方向端縁部1aを連結材３'の保持部3b'内に挿入すると共に他方の幅方向端縁部（下側の幅方向端縁部）1bに形成されている係合部を既固定のサイディング材１の一方の幅方向端縁部1bに形成されている係合部に係合させた後、この係合させたサイディング材１の一方の幅方向端縁部1bに形成されている固定部を釘やタッピンビス等の固定具により躯体７に固定する。この作業を連結材３’の両側について施工すべき壁面の全高さに亘って繰返し行って建築物の壁面における出隅を施工していたのである。
【０００７】
しかしながら、前記した如き従来の連結材３'を使用して出隅部分を施工する方法では、連結材３'が金属板を折曲して形成されているので、保持部3b'内にサイディング材１の長手方向端縁部1aを保持せしめたときにサイディング材１の表面と保持部3b'との間に隙間が生じて雨水が侵入し易いため、この隙間をコーキング材等により閉塞していたので施工に手間を要するという欠点があり、また図６に示す従来例の場合には連結材３'の頂部3c'の裏面側は空間3d'であり強度が弱いという欠点もあり、更に出隅部分の形状が限定されるという欠点があった。
【０００８】
【発明が解決しようとする課題】
本発明は、前記従来技術の欠点を解消し、乾式のサイディング材を躯体に固定すると共に出隅部分に出隅用外壁材を固定して建築物の壁面における出隅を施工するに際し、出隅用外壁材の固定及びこの出隅用外壁材の側方に隣接するサイディング材と前記出隅用外壁材との接続を効率良く、且つ意匠性に優れた状態に施工することができるばかりでなく、補修や微調整を行う場合などにサイディング材を痛めることがなく、しかも全作業を最初からやり直す必要がない建築物の壁面における出隅構造及びその施工方法を提供することを課題とする。
【０００９】
【課題を解決するための手段】
本発明者らは、かかる課題を解決すべく鋭意検討した結果、乾式のサイディング材が長手方向及び幅方向に順次固定されて成る建築物の壁面における出隅部分が、出隅用外壁材を支持せしめる本体と、該本体の両側縁部の表面側に設けられている係止部付嵌合溝と、該嵌合溝の該本体側であって表面側に形成されており該本体との境界部で該本体に対して可撓性を有しており該本体の表面とで出隅用外壁材の側縁を挾持せしめる出隅用外壁材用挾持片と、該嵌合溝の該本体と反対側であって表面側に形成されており該本体との境界部で該本体に対して可撓性を有するサイディング材用の表面側挾持片と、前記嵌合溝の該本体と反対側であって裏面側に形成されており建築物の躯体に固定具によって固定されたサイディング材用の裏面側挾持片とを備えた長尺状の連結材により、出隅用外壁材がその裏面を本体の表面に支持されていると共にその両側縁部を該本体と出隅用外壁材用挾持片とで挾持されており、該連結材の両側縁部に形成されているサイディング材用の表面側挾持片と裏面側挾持片とで出隅部分を挟んで配置されたサイディング材の長手方向端縁部がそれぞれ挾持されており、該連結材の嵌合溝の横断面形状に略合致する横断面形状に形成されており前記係止部に係止される係止部が形成されている長尺状の嵌合片が該連結材の嵌合溝に嵌合されていれば、意匠性に優れ且つサイディング材の長手方向への接続が強固な壁面構造とすることができるばかりでなく、補修や微調整を行う場合などに嵌合片を取り外すだけでサイディング材を痛めることなく全作業を最初からやり直す必要がないことを究明して本発明を完成したのである。
【００１０】
また前記建築物の壁面における出隅構造において、連結材が本体の裏面側に長手方向と平行に形成された断面Ｖ字状の溝状部で裏面側に所定角度に折曲されて躯体に固定されていると、隣接する壁面が直角などの所定角度を成す出隅部分を容易に施工することができ、連結材が屈曲自在な本体を湾曲された状態にして躯体に固定されていると、湾曲状を成す出隅部分を容易に施工することができ、意匠性の優れた出隅構造とすることができることも究明した。
【００１１】
そして、乾式のサイディング材が長手方向及び幅方向に順次固定されて成る建築物の壁面における出隅部分を施工するに際しては、先ず、出隅用外壁材を支持せしめる本体と、該本体の両側縁部の表面側に設けられている係止部付嵌合溝と、該嵌合溝の該本体側であって表面側に形成されており該本体との境界部で該本体に対して可撓性を有しており該本体の表面とで出隅用外壁材の側縁を挾持せしめる出隅用外壁材用挾持片と、該嵌合溝の該本体と反対側であって表面側に形成されており該本体との境界部で該本体に対して可撓性を有するサイディング材用の表面側挾持片と、前記嵌合溝の該本体と反対側であって裏面側に形成されており建築物の躯体に固定具によって固定されるサイディング材用の裏面側挾持片とを備えた長尺状の連結材を、出隅部分にサイディング材用の裏面側挾持片で固定具によって固定すると共に出隅用外壁材用挾持片を表側に屈曲して出隅用外壁材の両側縁部を押し込むと共に該出隅用外壁材用挾持片の屈曲状態を元の状態に戻して出隅用外壁材の両側縁部を挾持する。この連結材に出隅用外壁材の両側縁部を挾持する作業は、連結材を躯体に固定する前に行うこともできる。
【００１２】
また出隅部分を挟んだ両側縁部では、サイディング材用の表面側挾持片を表側に屈曲して固定すべきサイディング材の長手方向端縁部を押し込んで該サイディング材に形成されている固定部を固定具により躯体に固定したら該サイディング材の幅方向について該サイディング材の一方の幅方向端縁部に形成されている係合部に次に固定すべきサイディング材の他方の幅方向端縁部に形成されている係合部を係合して該サイディング材に形成されている固定部を固定具により躯体に固定する作業を繰返し行い、しかる後に前記連結材の屈曲した該サイディング材用の表面側挾持片の屈曲状態を元の状態に戻して該サイディング材用の表面側と裏面側との挾持片によってサイディング材の長手方向端縁部を挾持した後、前記連結材の嵌合溝の横断面形状に略合致する横断面形状に形成されており前記係止部に係止される係止部が形成されている長尺状の嵌合片を連結材の嵌合溝の全長に亘って嵌合して連結材の形状を維持させれば、前記した本発明に係る建築物の壁面における出隅構造を効率良く施工することができ、また躯体として既設の壁面をそのまま使用するリフォームとしての建築物の壁面の施工も可能であることを究明した。
【００１３】
更に、連結材としてサイディング材用の裏面側挾持片の基端部側にサイディング材の長手方向端縁部に当接するストッパが形成されているものを使用すると、サイディング材の長手方向端縁部を挾持する際にサイディング材の位置決めが容易でしかもサイディング材用の表面側挾持片を表側に屈曲する作業を容易に且つ確実に行うことができ、連結材として本体の裏面側に長手方向と平行な断面Ｖ字状の溝状部が形成されているものを使用すると、隣接する壁面が直角を成す出隅部分を容易に施工することができ、また連結材として屈曲自在な本体が形成されているものを使用すると、湾曲状を成す出隅部分を容易に施工することができることも究明して本発明を完成したのである。
【００１４】
【発明の実施の形態】
以下、図面により本発明に係る建築物の壁面における出隅構造及びその施工方法について詳細に説明する。
図１は本発明方法を実施してサイディング材を横張り固定した本発明に係る建築物の壁面における出隅構造の１例を示す斜視説明図、図２は図１における連結材の端部近傍を示す横断面拡大説明図、図３は図２におけるＡ−Ａ線断面図、図４及び図５はそれぞれ本発明方法で使用される連結材の１例であって躯体に取り付ける前の状態を示す横断面説明図である。
【００１５】
図面中、１は建築物の壁面における出隅部分の両側の壁面を構成するための乾式のサイディング材であり、樋状の金属板の樋内に合成樹脂発泡体が充填されており必要に応じて裏面にアルミニウム箔をラミネートされた紙や金属板等の裏面材により被覆されている金属サイディング材や、セメント，コンクリート等より成形されている窯業サイディング材等、従来より一般に使用されている乾式のサイディング材をそのまま使用することができる。この乾式のサイディング材１には、通常、長手方向と平行な両側の幅方向端縁部1b，1bのうち、一方の幅方向端縁部1bに凹部が形成された雌型の係合部1cが、また他方の幅方向端縁部1bにこの雌型の係合部1cに係合する雄型の係合部1dがそれぞれ形成されており、更にこれら係合部1c又は1dのいずれか一方の端縁側（裏面側）が外方に突出せしめられて固定部1eが形成されている（図３に示す実施例の場合には、一方の幅方向端縁部1bに雌型の係合部1cが形成されていると共にこの雌型の係合部1cの更に端縁側に固定部1eが延設されており、他方の幅方向端縁部1bに雄型の係合部1dが形成されている）。
【００１６】
２は建築物の壁面における出隅部分を構成するための出隅用外壁材であり、施工すべき出隅部分の形状に予め形成されているものや、鋼板等の屈曲自在な材質より成るものを使用することができる。この出隅用外壁材２は、通常施工すべき出隅部分の形状に対応する所定の形状に予め形成されているものを使用するが、鋼板等の屈曲自在な材質より成るものを使用することもできる。
また、この乾式の出隅用外壁材２は、高さ方向に長尺であることが施工の手間が少なく効率良く施工することができて好ましい。
【００１７】
３は屈曲又は折曲されて前記出隅用外壁材２をその表面側に支持せしめる本体3aと、この本体3aの両側縁部の表面側に設けられている係止部3ea付嵌合溝3eと、この嵌合溝3eの本体3a側であって表面側に形成されており本体3aとの境界部で本体3aに対して可撓性を有しており本体3aの表面とで出隅用外壁材２の側縁を挾持せしめる出隅用外壁材用挾持片3bと、前記嵌合溝3eの本体3aと反対側の表面側に形成されており本体3aとの境界部で本体3aに対して可撓性を有するサイディング材用の表面側挾持片3cと、前記嵌合溝3eの本体3aと反対側の裏面側に形成されており建築物の躯体７に固定具８によって固定されるサイディング材用の裏面側挾持片3dとを備えており、少なくとも本体3aを除いた部分である出隅用外壁材用挾持片3b，サイディング材用の表面側挾持片3c及び裏面側挾持片3dがゴムや合成樹脂等より成る長尺状の連結材であり、本体3aは施工すべき出隅部分の形状に形成されているか又はゴムや合成樹脂等より屈曲自在に形成されている。また本体3aの両側縁部の表面側に設けられている係止部3ea付嵌合溝3eとしては、図２に示す如く断面略矩形状や図５に示す如く断面略Ｖ字状等種々の形状を採用することができる。
【００１８】
このような連結材３のサイディング材用の表面側挾持片3cと裏面側挾持片3dとにより、出隅部分を挟んで配置されたサイディング材１の長手方向端縁部1aの表裏面が本体3aの両側縁部で挾持され、また連結材３の本体3aの表面と出隅用外壁材用挾持片3bとにより出隅用外壁材２の両側縁が挾持される。
【００１９】
４は連結材３の嵌合溝3eの横断面形状に略合致する横断面形状に形成されており連結材３の嵌合溝3eの係止部3eaに係止される係止部4aが形成されている長尺状の嵌合片であり、連結材３の嵌合溝3eに嵌合されるとこの嵌合溝3eの両側に形成されている出隅用外壁材用挾持片3b及びサイディング材用の表面側挾持片3cが屈曲することのない状態に連結材３の形状が維持せしめられる。すなわち、嵌合片４が連結材３の嵌合溝3e内に嵌入されて嵌合片４の係止部4aが連結材３の嵌合溝3eの係止部3eaに係止されると、連結材３の嵌合溝3eの本体3a側に形成されていて本体3aとの境界部で本体3aに対して可撓性を有する出隅用外壁材用挾持片3bの裏面が出隅用外壁材２の側縁の表面に当接した状態で、及び連結材３の嵌合溝3eの本体3aと反対側の表面側に形成されていて本体3aとの境界部で本体3aに対して可撓性を有するサイディング材用の表面側挾持片3cの裏面がサイディング材１の長手方向端縁部1aの表面に当接した状態で、それぞれその可撓性を阻害されてこれら挾持片3b及び3cが屈曲することのない状態に連結材３の形状が維持せしめられるのである。
【００２０】
次に、前述した如く構成される本発明に係る建築物の壁面における出隅構造を施工する本発明方法について説明する。
【００２１】
前述した如き本発明に係る建築物の壁面における出隅構造を施工するには、先ず、長尺状の連結材３をサイディング材用の裏面側挾持片3dで固定具８によって躯体７の出隅部分に固定すると共に、連結材３の本体3aの表面に出隅用外壁材２を支持させるのである。
【００２２】
連結材３を躯体７に固定するには、連結材３の両側縁部に形成されているサイディング材用の裏面側挾持片3dで固定具８によって固定するのであり、このとき連結材３の本体3aがゴムや合成樹脂等より屈曲自在に形成されている場合には、平板状を成している本体3aを屈曲せしめて躯体７の出隅部分を挟むように連結材３を配置して前記した如く固定具８によって躯体７に固定し、また本体3aが施工すべき出隅部分の形状に予め形成されている場合には、連結材３を躯体７の出隅部分を挟むように配置して前記した如く固定具８によって躯体７に固定する。
【００２３】
また、出隅用外壁材２を連結材３に支持させるのは、連結材３の出隅用外壁材用挾持片3bを表側に屈曲して出隅用外壁材２の両側縁を押し込むと共にこの出隅用外壁材用挾持片3bの屈曲状態を元の状態に戻して行うのであり、出隅用外壁材２の連結材３への支持は、連結材３を躯体７に固定する前又は固定した後のいずれであっても良い。
【００２４】
ここで、連結材３としては、本体3aが施工すべき出隅部分の形状に予め形成されているものとゴムや合成樹脂等より屈曲自在に形成されているものとのいずれも使用することができ、また出隅用外壁材２としても、前記した如く屈曲自在に形成されているものと施工すべき出隅部分の形状に予め形成されているものとのいずれも使用することができる。
【００２５】
連結材３及び出隅用外壁材２として、前記いずれの態様を使用するか、更に出隅用外壁材２の連結材３への支持を連結材３を躯体７に固定する前又は固定した後のいずれにするかは、意匠性及び施工効率を考慮して適宜決定される。
【００２６】
ここで、出隅用外壁材２として本体3aが屈曲自在に形成されているものを、そして出隅用外壁材２として屈曲自在に形成されているものをそれぞれ使用し且つこれらを一体にして躯体７の出隅部分を挟むように配置して固定具８によって躯体７に固定するする場合には、出隅用外壁材用挾持片3bを表側に屈曲して出隅用外壁材２の両側縁を押し込むと共にこの出隅用外壁材用挾持片3bの屈曲状態を元の状態に戻して、出隅用外壁材２の裏面及び／又は連結材３の本体3aの表面に塗布した接着剤により連結材３の本体3aに出隅用外壁材２を接着固定した後、施工すべき出隅部分に出隅用外壁材２を固定された連結材３の本体3aを出隅用外壁材２と共に屈曲してサイディング材用の裏面側挾持片3dで固定具８によって躯体７に固定する。
【００２７】
また、連結材３の本体3aの裏面側に長手方向と平行な断面Ｖ字状の溝状部3aaが形成されていると、出隅部分を挾んで隣接する平面状の壁面が所定の角度に形成される出隅部分を施工する場合に、連結材３の本体3aをこの角度（通常９０度が最も多いが、この角度に限定されるものではない）に対応して良好な状態に容易に折曲することができる。
【００２８】
また、連結材３を固定される躯体７は、新たに壁面を施工する場合には柱であり、また既設の壁面を改修する場合には既設の壁面をそのまま使用することができる。
【００２９】
そして、躯体７に固定された連結材３の両側縁部のサイディング材用の表面側挾持片3cと裏面側挾持片3dとにより、出隅部分を挾んで配置されるサイディング材１の長手方向端縁部1aの表裏面を挾持すると共にこのサイディング材１を躯体７に固定する。
すなわち、サイディング材用の表面側挾持片3cを表側に屈曲して固定すべきサイディング材１の一方の長手方向端縁部1aを押し込んでこのサイディング材１に形成されている固定部1eを固定具５により躯体７に固定したら、サイディング材１の幅方向についてこのサイディング材１の一方の幅方向端縁部1bに形成されている係合部1cに次に固定すべきサイディング材１の他方の幅方向端縁部1bに形成されている係合部1dを係合してサイディング材１に形成されている固定部1eを固定具５により躯体７に固定する作業を繰返し行う。
【００３０】
しかる後、連結材３の屈曲したサイディング材用の表面側挾持片3cの屈曲状態を元の状態に戻してサイディング材用の表面側と裏面側との挾持片3c，3dによって躯体７に固定された各サイディング材１の長手方向端縁部1aを挾持させた後、連結材３の嵌合溝3eの横断面形状に略合致する横断面形状に形成されており連結材３の嵌合溝3eの係止部3eaに係止される係止部4aが形成されている長尺状の嵌合片４を、連結材３の嵌合溝3eの全長に亘って嵌合して連結材３の形状を維持させる。
【００３１】
この際、連結材３として、サイディング材用の裏面側挾持片3dの基端部側にサイディング材１の長手方向端縁部1aを係止するストッパ3fが形成されているものを使用すると、サイディング材１の長手方向端縁部1aの位置決めが容易で、しかもサイディング材１の長手方向端縁部1aが連結材３の本体3aから離れて位置するので、サイディング材用の表面側挾持片3cの屈曲を連結材３の素材に大きな内部応力を作用させること無くより確実に行うことができる。
【００３２】
このような作業において、サイディング材１の幅方向への接続は、幅方向端縁部1b，1bに形成されている係合部1c，1dの形状によって種々の態様があり、例えば幅方向端縁部1b，1b同士を当接した状態に単に突き合わせた態様や、また幅方向端縁部1b，1b同士を間隔を隔てた状態に突き合わせてこの隙間にコーキング材を充填した態様を挙げることができる他、施工効率を考慮してコーキング材の代わりに以下に説明する如き目地材６を使用した態様を示すこともできる。
【００３３】
すなわち、例えば図３に示す如く、サイディング材１の幅方向端縁部1bに形成されている係合部1c，1dの断面形状がそれぞれ表面側が側方に突出して裏面側に凹部が形成されていて、サイディング材１，１を幅方向に接続した際には幅方向端縁部1b，1bの凹部を含む間隔を塞ぐために弾性を有する目地材６を嵌合するものである。この目地材６としては、その断面形状がサイディング材１の幅方向端縁部1bに形成されている係合部1c，1dの表面側の突出部間に嵌合される狭幅部分から段差を介して凹部間に嵌合される広幅部分が形成されており、ゴムや合成樹脂等よりなる弾性を有する中空状に形成されている態様を示すことができる。
【００３４】
【発明の効果】
以上に詳述した如く本発明に係る建築物の壁面の出隅構造は、本体の両側縁部の表面側に嵌合溝が形成されていると共にこの嵌合溝に係止部が形成されている長尺状の連結材の嵌合溝の本体側では、本体と出隅用外壁材用挾持片とにより出隅用外壁材の側縁部が挾持されており、また嵌合溝の本体と反対側では、サイディング材用の表面側挾持片とサイディング材用の裏面側挾持片とによりサイディング材の長手方向端縁部が挾持されており、前記連結材の嵌合溝の断面形状に略合致する断面形状に形成されている嵌合片が連結材の嵌合溝に嵌合されて連結材の形状が維持されているので、連結材によってサイディング材の長手方向端縁部に強固に保持されており、しかも出隅用外壁材の側縁部表面に出隅用外壁材用挾持片が、またサイディング材の長手方向端縁部表面に連結材のサイディング材用の表面側挾持片が強固に密着するので意匠効果が高い。
【００３５】
また、出隅部分に支持される出隅用外壁材の裏面側には連結材の本体が存在しているので、出隅用外壁材がサイディング材と同様のそれ自身で高い強度を有している場合でも、また鋼板等屈曲自在でそれ自身では強度が弱いものでも、施工された出隅部分は比較的高い強度を有している。
【００３６】
連結材の本体を、出隅部分に隣接する壁面に対応する所定の角度を有する状態や屈曲した状態等種々の状態に形成することができ、種々の形状の出隅部分を高い強度を有する状態に施工することができる。
【００３７】
そして、前記構成の本発明に係る建築物の壁面の出隅構造を施工すべく本発明方法を実施すると、躯体の出隅部分に配置した連結材の出隅用外壁材用挾持片を表側に屈曲して、支持すべき出隅用外壁材の側縁部を押し込んで固定した後、屈曲した出隅用外壁材用挾持片を屈曲状態を元の状態に戻し、またサイディング材用の表面側挾持片を表側に屈曲して、固定すべきサイディング材の長手方向端縁部を押し込んで固定した後、屈曲したサイディング材用の表面側挾持片を屈曲状態を元の状態に戻し、しかる後嵌合溝に嵌合片を嵌入する簡単な作業によって連結材に出隅用外壁材の側縁部及びサイディング材の長手方向端縁部を挾持でき、出隅部分に出隅用外壁材及びサイディング材を効率良く行うことができる。
【００３８】
このような本発明方法は、新たに壁面を施工する場合及び既設の壁面をそのまま使用してその外面側に改修用のサイディング材を固定して改修壁面を施工する場合のいずれにも採用することができる。
【００３９】
そして、この本発明方法により壁面を施工すると、嵌合片を連結材の嵌合溝から抜き取るだけで、サイディング材の取付位置の微調整や、施工後に或るサイディング材のみを交換することも容易に行うことができるのである。
【００４０】
このように種々の効果を奏する本発明に係る建築物の壁面の出隅構造及びその施工方法は、その工業的価値の非常に大きなものである。

Such a siding material is usually formed with engaging portions that engage with each other in the width direction end edges of the siding material that are fixed adjacent to each other at both end edges in the width direction parallel to the longitudinal direction. The engaging portion is provided with a fixing portion that is fixed to the building frame with a nail or a screw. And in order to fix the siding material in the width direction, after engaging the other engaging part of the siding material fixed next to one engaging part of the siding material fixed previously, the column, When refurbishing studs, trunk edges, and existing wall surfaces, repeat the work of fixing them directly to the existing wall materials or to the chassis edges, etc., that are newly fixed on the existing wall materials with fixing tools such as tapping screws. Do it.
[0004]
In addition, in order to construct a protruding corner portion on a wall surface that is to be horizontally stretched using such a siding material, the angle between the adjacent wall surfaces in the longitudinal direction of the siding material and the edge on the protruding corner portion side is set. Arranged in a state where the edges are abutted with each other formed at an angle of 1/2, or the edges of one siding material are brought into contact with the edges of the other siding material. If fixed, not only the appearance will be bad, but also rainwater will invade from the abutted part and if the siding material is a metal siding material, a phenomenon of corroding the metal plate or synthetic resin foam may occur, and further, the siding material etc. As a result of the dimensional error, gaps may occur in the abutting part.Therefore, even if the siding material is a metal siding material or a ceramic siding material, it is adjacent at the protruding corner. Between the edge portions of the siding material connecting material is used to conceal the edge.
[0005]
As this connecting material, a holding part into which the edge of the siding material is inserted toward each adjacent wall surface side by bending a metal plate is formed, for example, as shown in FIGS. A substantially central portion is bent to the back surface side at an angle formed by adjacent wall surfaces to form a top portion 3c ′ of the protruding corner portion, and 180 ° on the back surface side at a predetermined distance from both sides of the top portion 3c ′. A holding portion 3b that is folded back at an angle of 90 ° and then bent at an angle of 90 ° on the surface side and further bent at an angle of 90 ° on the surface side to insert the longitudinal edge 1a of the siding material 1 Made of a metal plate in which a fixing portion 3a 'is formed which protrudes outward from a line folded back at an angle of 180 degrees and is fixed to the housing 7 with a nail or a tapping screw 8 The long connecting material 3 ′ can be exemplified.
[0006]
A method for constructing the protruding corner portion by using the conventional connecting material 3 ′ and fixing the siding material 1 as described above to the horizontal stretch will be briefly described.
First, as shown in FIGS. 6 and 7, the fixing portion 3a ′ of the connecting member 3 ′ is fixed in advance to the casing 7 of the protruding corner portion by a fixing tool 8 such as a nail or a tapping screw.
Usually, the longitudinal direction edge 1a of the siding material 1 is inserted horizontally into the holding portion 3b ′ with the longitudinal direction of the siding material 1 being horizontal below the wall surface to be constructed. (Normally, the upper edge in the width direction) A siding in which a fixing portion extending to 1b is fixed to the housing 7 with a fixing tool such as a nail or a tapping screw, and then fixed above the already fixed siding material 1. An engaging portion formed on the other widthwise edge (lower widthwise edge) 1b while inserting the longitudinal edge 1a of the material 1 into the holding portion 3b ′ of the connecting material 3 ′ Is engaged with an engaging portion formed on one widthwise edge 1b of the fixed siding material 1, and then formed on one widthwise edge 1b of the engaged siding material 1. The fixed portion is fixed to the housing 7 with a fixing tool such as a nail or a tapping screw. This work was repeated over the entire height of the wall surface to be constructed on both sides of the connecting material 3 ′ to construct the corners on the wall surface of the building.
[0007]
However, in the method of constructing the protruding corner portion using the conventional connecting material 3 ′ as described above, since the connecting material 3 ′ is formed by bending a metal plate, the siding material is formed in the holding portion 3b ′. Since the gap between the surface of the siding material 1 and the holding part 3b ′ is generated when the edge 1a in the longitudinal direction 1 is held and rainwater easily enters, the gap is closed with a caulking material or the like. Therefore, there is a disadvantage that it takes time and labor for the construction, and in the case of the conventional example shown in FIG. 6, the back side of the top portion 3c 'of the connecting member 3' is a space 3d 'and the strength is weak. There was a drawback that the shape of the part was limited.
[0008]

When constructing the projected corner portion to be formed, the main body 3a of the connecting material 3 can be easily put into a good state corresponding to this angle (usually 90 degrees is the largest, but is not limited to this angle). Can be bent.
[0028]
Further, the frame 7 to which the connecting material 3 is fixed is a pillar when a new wall surface is constructed, and the existing wall surface can be used as it is when the existing wall surface is repaired.
[0029]
The longitudinal ends of the siding material 1 arranged with the protruding corner portion sandwiched between the front side holding pieces 3c and the back side holding pieces 3d for the siding material at both side edges of the connecting member 3 fixed to the casing 7 While holding the front and back surfaces of the edge portion 1 a, the siding material 1 is fixed to the housing 7.
That is, the front side holding piece 3c for siding material is bent to the front side and one longitudinal end edge 1a of the siding material 1 to be fixed is pushed in to fix the fixing portion 1e formed on the siding material 1 5, the other width of the siding material 1 to be fixed next to the engaging portion 1 c formed on one widthwise edge 1 b of the siding material 1 in the width direction of the siding material 1. The operation of fixing the fixing portion 1e formed on the siding material 1 to the housing 7 by the fixing tool 5 by engaging the engaging portion 1d formed on the directional edge 1b is repeated.
[0030]
Thereafter, the bent state of the front side holding piece 3c for the siding material bent of the connecting material 3 is returned to the original state, and is fixed to the casing 7 by the holding pieces 3c and 3d of the front side and the back side for the siding material. After holding the longitudinal edge 1a of each siding material 1, it is formed in a cross-sectional shape substantially matching the cross-sectional shape of the fitting groove 3e of the connecting material 3, and the fitting groove 3e of the connecting material 3 The long fitting piece 4 formed with the locking portion 4a to be locked to the locking portion 3ea is fitted over the entire length of the fitting groove 3e of the connecting material 3 to Maintain shape.
[0031]
At this time, if a connecting member 3 is used in which a stopper 3f for locking the longitudinal edge 1a of the siding material 1 is formed on the base end side of the back side holding piece 3d for siding material, siding Positioning of the longitudinal edge 1a of the material 1 is easy, and the longitudinal edge 1a of the siding material 1 is located away from the main body 3a of the connecting material 3, so that the surface side holding piece 3c for the siding material 1 The bending can be more reliably performed without applying a large internal stress to the material of the connecting material 3.
[0032]
In such an operation, the connection of the siding material 1 in the width direction has various modes depending on the shapes of the engaging portions 1c and 1d formed on the width direction edge portions 1b and 1b. A mode in which the portions 1b and 1b are in contact with each other, and a mode in which the width direction edge portions 1b and 1b are in a state of being spaced apart and a caulking material is filled in the gap can be exemplified. In addition, in consideration of construction efficiency, a mode in which the joint material 6 described below is used instead of the caulking material can be shown.
[0033]
That is, for example, as shown in FIG. 3, the cross-sectional shapes of the engaging portions 1c and 1d formed on the edge portion 1b in the width direction of the siding material 1 are protruded sideways on the front side and recessed on the back side. Thus, when the siding materials 1 and 1 are connected in the width direction, the joint material 6 having elasticity is fitted to close the space including the concave portions of the width direction edge portions 1b and 1b. As this joint material 6, the cross-sectional shape has a level difference from the narrow part fitted between the protrusions on the surface side of the engaging parts 1c, 1d formed in the edge part 1b in the width direction of the siding material 1. The wide part fitted between recessed parts is formed, and the aspect currently formed in the hollow shape which has elasticity which consists of rubber | gum, a synthetic resin, etc. can be shown.
[0034]
【The invention's effect】
