Description

【０００１】
【発明の属する技術分野】
本発明は、耐久性に優れ、特に強風による風圧に対する強度に優れ、且つ施工においても簡易且つ迅速に行うことができる壁板材及び壁体に関する。
【０００２】
【従来の技術】
従来より、種々の壁板材が存在している。多くの壁材は、胴縁等の構造材に並設し、隣接する壁板材の端部同士を連結するものである。このとき、外観を良好なるものとすることで、その連結部分は、ビス等の固着具が露出しないようになっている。そして、隣接する壁板材の端部同士は、重合させたり、種々の係止構造により接続されている。
【０００３】
【発明が解決しようとする課題】
ところで、従来の壁板材同士の連結部分は、胴縁等の構造材に固着具を介して固着されている側は、強度が保たれるが、隣接する壁板材で、前位の壁板材の端部に係止されて連結される部位は比較的強度が弱い場合が多い。そのために、強風等により壁面に作用する負圧により、壁板材が剥がれるように外力がかかることになる。
【０００４】
そのために、壁板材の端部同士の連結箇所は、特に強風による負圧が作用して、表面側に位置する壁板材の端部が剥がれてしまい、壁体そのものを破損することになる。そのために、隣接する壁板材同士の連結部位は、十分な強度を保持するようにしなければならない。しかし、十分な強度を保持する構造となると、まず複雑なる構造となり、それにともなって、壁体の施工の複雑且つ面倒となるものであった。
【０００５】
【課題を解決するための手段】
そこで、発明者は上記課題を解決すべく、鋭意，研究を重ねた結果、本発明を、主板と、該主板の幅方向両側に折曲形成された側部と、一方側の側部から前記主板と平行な内方側に形成される折返し状部と、該折返し状部の内端より折返し状に形成され，且つ該折返し状部とで被挿入空隙室部を構成し，その外端には折返し状の立上り端縁が形成された取付用板部と、前記側部と折返し状部との折返し位置の角部に形成されると共に該折返し状部からその一部が略膨出状に突出するように形成され，且つ前記取付用板部側に向かって形成された被係止部と、前記他方側の側部から主板の外方側に向かって形成された挿入板部と、該挿入板部の表面側に形成された係止部とからなる壁板材及びその壁体等としたことにより、耐久性に優れ、特に強風による風圧に対する強度に優れ、且つ施工においても簡易且つ迅速に行うことができ上記課題を解決したものである。
【０００６】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。本発明の壁板材Ａは、主に、主板１と、側部２，２、被係止部３、折返し状部４、取付用板部５、挿入板部７及び係止部８とから構成されている。まず、主板１の幅方向両端には側部２，２が形成されている。該側部２，２は、主板１に対して傾斜状に形成されたものである〔図２（Ａ）参照〕。その主板１と側部２，２とが略台形状を構成する〔図２（Ｂ），図３等参照〕。
【０００７】
また、主板１には、適宜の箇所に凹み状の凹部１ａ，１ａ，…が形成されている。該凹部１ａにより、主板１には、複数の台形状の部位が形成されることになり、壁板材Ａの形状に種々のバリエーションを与えるものである〔図２（Ｂ），図３等参照〕。
【０００８】
また、その凹部１ａの形状は、図示された台形状に限定されるものではなく、三角形状，円弧形状等の種々の形状にしても構わない。さらに、主板１には、凹部１ａが形成されない実施例も存在する〔図７（Ａ）参照〕。該実施例では主板１が台形状をなしている。
【０００９】
その主板１の一端側の側部２には、折返し状部４及び取付用板部５がそれぞれ形成されている〔図２（Ｂ），（Ｃ）参照〕。まず、折返し状部４は、前記側部２の端部から屈曲形成されたもので、前記主板１と平行な面を有している。また、前記取付用板部５は、折返し状部４に対してその裏面側に略折返し状に形成されたものである。
【００１０】
また、前記取付用板部５の一部は、前記側部２から主板１の外方に向かって突出するように形成されたものである。そして、前記折返し状部４と取付用板部５との対向する箇所では偏平状の空隙室を構成される。該空隙室を被挿入空隙室部ｓと称する。
【００１１】
その側部２と折返し状部４との折曲箇所には、被係止部３が形成されている〔図２（Ｃ）参照〕。該被係止部３は、折返し状部４からその一部が略膨出状に突出するように形成され、具体的にはその折返し状部４から対向する取付用板部５に向かって形成されたものである。
【００１２】
また、被係止部３の形成位置は、前記側部２と折返し状部４との折返し位置の角部に形成されている〔図２（Ｃ）参照〕。或いは、その側部２と折返し状部４との折り曲げ箇所から少し奥側に形成されることもある〔図７（Ｂ）参照〕。また、被係止部３の奥側（被挿入空隙室部ｓの奥方向）の面を略垂直状に形成し、係止部８との係止状態をより一層強固なものにすることもある〔図７（Ｃ）参照〕。
【００１３】
その取付用板部５は、前述したように折返し状部４の端部と折返し状に屈曲され、且つ折返し状部４と略平行に形成されている〔図２（Ｃ）参照〕。そして、折返し状部４と取付用板部５の両面にて形成された被挿入空隙室部ｓに別の壁板材Ａの挿入板部７が挿入することができるようになっている。
【００１４】
その取付用板部５は、平坦状に形成されている。その取付用板部５は、主板１の幅方向端部に形成された側部２からさらに外方に突出して形成されたものであり、その取付用板部５の外端には表面側に立上り端縁５ａが形成されている〔図２（Ｂ），（Ｃ）参照〕。
【００１５】
また、その取付用板部５の側部２から外方に突出した部分には、表面側に突出するようにして、支持突起部６が形成されている。該支持突起部６は、前記主板１と折返し状部４との折返し部分から離間して形成されている。また、その支持突起部６は、隣接する別の壁板材Ａの挿入板部７が挿入することができる程度に主板１と折返し状部４との折返し部分から離間していればよい。さらに、取付用板部５から支持突起部６の高さ寸法は、前記立上り端縁５ａの高さと略同等である。
【００１６】
その支持突起部６と前記被係止部３とは、主板１に対して垂直方向において僅かに離間しており、該間隔の寸法は壁板材Ａを形成する金属板材の厚さに略等しい〔図２（Ｃ）参照〕。また、支持突起部６と前記被係止部３とが主板１に対して垂直方向に沿って離間していない実施例も存在する。また、図７（Ｄ）は、取付用板部５に、支持突起部６が形成されていない実施例である。
【００１７】
次に、前記主板１の幅方向他端側には、挿入板部７が形成されている。該挿入板部７は平坦状をなしている。該挿入板部７の表面側には、係止部８が形成されている。該係止部８は、前記被係止部３と係止するものである。その係止部８の具体的な形成位置は、挿入板部７の外端部分に形成されている〔図２（Ｂ）参照〕。
【００１８】
また、その係止部８の形状は挿入板部７の外端箇所を折返し状に形成したものである。また、係止部８の別の形状としては、前記被係止部３に係止可能な位置であれば、前記挿入板部７の外端箇所以外の適宜の箇所で表面側に突起状に形成されたものであってもかまわない。
【００１９】
その係止部８は、折返し状部４と取付用板部５との間に形成される被挿入空隙室部ｓに前記挿入板部７を挿入したときに、前記被係止部３と係止するようになっている。また、挿入板部７は、前記取付用板部５上に重合し、挿入板部７の裏面側が前記支持突起部６により支持されて被係止部３と係止部８との係止状態を維持するものである。
【００２０】
次に、壁板材Ａによる壁体の施工について説明する。まず、胴縁等の構造材１０が施工される。該構造材１０は、断面略Ｃ字形状のチャンネル鋼材，リップ溝型材等である。その構造材１０は上下方向に複数施工される。その構造材１０に対して直角状に壁板材Ａを配置し、取付用板部５がドリルビス等の固着具１１にて固着される〔図５（Ａ）参照〕。
【００２１】
次いで、隣接する次位の壁板材Ａの挿入板部７を前位の壁板材Ａの被挿入空隙室部ｓに挿入する〔図４（Ａ），（Ｂ）参照〕。このとき、隣接する次位の壁板材Ａは、前位の壁板材Ａに対して傾斜状にして挿入板部７を挿入する〔図５（Ａ）参照〕。該挿入板部７は、被挿入空隙室部ｓに挿入すると、係止部８と被係止部３とが係止する〔図５（Ｂ）参照〕。
【００２２】
そして、隣接する次位の壁板材Ａを前位の壁板材Ａと同一平面となるようにすることで、前記被係止部３と係止部８との係止が確実となる。さらに、次位の壁板材Ａの挿入板部７は、前位の壁板材Ａの取付用板部５に形成された支持突起部６により略押圧状態となり、その被係止部３と係止部８との係止状態を常時，一定に維持することができる。このように、隣接する壁板材Ａ，Ａ同士を前記被挿入空隙室部ｓに挿入板部７を挿入して連結し、これを繰り返すことで壁体が施工される〔図１（Ａ），（Ｂ）及び図４（Ａ），（Ｂ）等参照〕。
【００２３】
上記のように施工された壁体に強風による負圧ｐ，ｐ，…が作用したときの状態について説明する。その壁板材Ａに負圧ｐ，ｐ，…が作用すると、壁板材Ａが剥がされる方向に外力がかかる〔図６（Ａ）参照〕。そのとき、壁板材Ａは、取付用板部５が固着具１１により構造材１０に固着されているので、実際には挿入板部７側が前位の壁板材Ａの被挿入空隙室部ｓから外れようとする外力がかかることになる〔図６（Ｂ）参照〕。
【００２４】
さらに、壁板材Ａに負圧ｐ，ｐ，…がかかった状態では、壁板材Ａは略偏平円弧状に撓むことになり、挿入板部７も前位の壁板材Ａの被挿入空隙室部ｓから傾斜状になりながら外れようとする。しかし、挿入板部７に形成された係止部８と前位の壁板材Ａに形成された被係止部３とが係止されているので、挿入板部７が前位の壁板材Ａの被挿入空隙室部ｓから外れることを防止できる〔図６（Ｃ）参照〕。
【００２５】
【発明の効果】
請求項１の発明は、主板１と、該主板１の幅方向両側に折曲形成された側部２と、一方側の側部２から前記主板１と平行な内方側に形成される折返し状部４と、該折返し状部４の内端より折返し状に形成され，且つ該折返し状部４とで被挿入空隙室部ｓを構成し，その外端には折返し状の立上り端縁５ａが形成された取付用板部５と、前記側部２と折返し状部４との折返し位置の角部に形成されると共に該折返し状部４からその一部が略膨出状に突出するように形成され，且つ前記取付用板部５側に向かって形成された被係止部３と、前記他方側の側部２から主板１の外方側に向かって形成された挿入板部７と、該挿入板部７の表面側に形成された係止部８とからなる壁板材としたことにより、該壁板材にて壁体を施工するのに簡易且つ迅速に行うことができる。また、形状が簡単であり、その製造を効率的に行うことができる。
【００２６】
上記効果を詳述すると、主板１の幅方向両側に形成された側部２，２から折返し状部４と取付用板部５とを折返し状に形成することで、該折返し状部４と取付用板部５とで被挿入空隙室部ｓが形成される。また、その空隙室ｓには被係止部３が形成されることとなる。
【００２７】
それゆえに、隣接する次位の壁板材Ａの挿入板部７を前位の壁板材Ａの折返し状部４と取付用板部５との間に形成される被挿入空隙室部ｓに挿入する。このとき、隣接する次位の壁板材Ａは、前位の壁板材Ａに対して傾斜状にして挿入板部７を挿入する。該挿入板部７は前記被挿入空隙室部ｓに挿入すると、被係止部３と係止部８とが係止する。そして、隣接する次位の壁板材Ａを前位の壁板材Ａと同一平面となるようにすることで、前記被係止部３と係止部８との係止が確実なものとすることができる。
【００２８】
さらに、次位の壁板材Ａの挿入板部７は、前位の壁板材Ａの取付用板部５に形成された立上り端縁５ａにより略押圧状態となり、その被係止部３と係止部８との係止状態を常時，一定に維持することができる。このように、隣接する壁板材Ａ，Ａ同士を被挿入空隙室部ｓと挿入板部７を介して連結し、これを繰り返すことで壁体が施工される。
【００２９】
また、施工された壁体に強風による負圧ｐ，ｐ，…が作用したときには、折返し状部４と取付用板部５との被挿入空隙室部ｓに挿入された挿入板部７が前記被係止部３と係止部８とが相互に係止して、離間する壁板材同士の連結箇所が外れるこを防止し、耐久性のあるものにすることができる。
【００３０】
次に、請求項２の発明は、請求項１において、前記取付用板部５には前記側部２より外方に突出した部分において表面側に支持突起部６が形成されてなる壁板材としたことにより、該支持突起部６が隣接する壁板材の挿入板部７を裏面側より押圧するように支持し、これによって、挿入板部７に形成された係止部８は前記被係止部３との係止状態をより一層，強固なるものとすることができるものである。
【００３１】
次に、請求項３の発明は、主板１と、該主板１の幅方向両側に折曲形成された側部２と、一方側の側部２から前記主板１と平行な内方側に形成される折返し状部４と、該折返し状部４の内端より折返し状に形成され，且つ該折返し状部４とで被挿入空隙室部ｓを構成し，その外端には折返し状の立上り端縁５ａが形成された取付用板部５と、前記側部２と折返し状部４との折返し位置の角部に形成されると共に該折返し状部４からその一部が略膨出状に突出するように形成され，且つ前記取付用板部５側に向かって形成された被係止部３と、前記他方側の側部２から主板１の外方側に向かって形成された挿入板部７と、該挿入板部７の表面側に形成された係止部８とからなる壁板材の取付用板部５が構造材に固着具を介して固着され、隣接する次位の壁板材の挿入板部７が前位の壁板材の被挿入空隙室部ｓに挿入され、前記係止部８と被係止部３とが係止され、前記挿入板部７は取付用板部５に形成された立上り端縁５ａと略当接状態となっている壁体としたことにより、施工が簡単であり、強風による耐久性を向上したものとすることができる。
【００３２】
上記効果を詳述する、隣接する壁板材Ａ，Ａは、その一方側に形成された被挿入空隙室部ｓに、隣接する他方側の壁板材の挿入板部７が挿入され、隣接する壁板材Ａ，Ａの被係止部３と係止部８とが係止する構造である。それゆえ、被挿入空隙室部ｓ内に挿入した挿入板部７は外れにくい構造である。特に、負圧ｐ，ｐ，…がかかると、一方の壁板材Ａが外方に向かって引っ張られることになるが、これによって被係止部３と係止部８とがより一層，強固に当接することとなり、強風に対する耐久性を向上させることができる。
【００３３】
また、隣接する壁板材Ａ，Ａ同士の連結においては、前位の壁板材Ａの被挿入空隙室部ｓに隣接する次位の壁板材Ａの挿入板部７を挿入するのみで略完了するもので施工が簡単にできる。さらに、取付用板部５を構造材１０にビス等の固着具１１を介して固着するものであるが、その固着具１１は隣接する壁板材Ａの挿入板部７により覆われることとなり、外観を良好にすることができる。また、取付用板部５の端部には表面側に立上り端縁５ａが形成されており、これが、壁体の樋状の役目をなし、雨仕舞を良好にしている。
