【発明の属する技術分野】
本発明は、１本の大棟を備えた本体屋根の屋根下地上に、該大棟と直交する方向の別の棟を備えた四面体からなる置き屋根が配設固定された構造を備えた屋根部を有する住宅の棟違い部の屋根構造に関する。
【０００２】
【従来の技術及び発明が解決しようとする課題】
住宅の屋根構造の一つとして、寄棟屋根、切妻屋根等の１本の大棟を備えた本体屋根における棟違い部を置き屋根構法という手段で構成した屋根構造がある。置き屋根構法は、本体屋根の屋根下地上の所定位置に、大棟と直交する方向の別の棟を備えた四面体からなる置き屋根を構成するものである。
従来の一般的な置き屋根の施工手順は、以下の通りである。先ず、本体屋根の骨組及び屋根下地を施工した後、前記四面体における底面の３角形状の枠体を構成する３辺のうち、本体屋根の勾配部分に敷設固定される２辺に該当する２本の谷木について、作業者が本体屋根上にて、その敷設固定する位置を計測、採寸する。次に、計測、採寸された前記敷設固定する位置を示す目印を、本体屋根に設ける。次いで、２本の谷木について、所定の長さに切断し、それぞれの一端を頂部取り合いの形状に加工する。そして、切断、加工された２本の谷木を、本体屋根に設けた前記目印に合わせて、本体屋根の屋根下地上に敷設固定する。
然る後、設計図面に表記された水平投影寸法を勾配なりの寸法に換算し、換算した寸法に基づいて、本体屋根に敷設固定した２本の谷木における、垂木、トラス等の骨組の構造材が設置される位置に位置墨を出す。次に、垂木、トラス等の骨組の構造材を、前記位置墨に合わせて、本体屋根の勾配方向に直交する方向に所定間隔隔離させて並べた状態で設置する。そして、置き屋根の骨組に置き屋根面を形成する部材を設置することにより、置き屋根を構成することができる。
【０００３】
しかし、置き屋根を前述の手順で構成する場合、屋根上という不安定なところで、作業者が谷木の採寸や切断等の作業をするため、作業者の姿勢が不安定となり、危険であった。
また、本体屋根の屋根下地上に谷木の敷設位置を出す作業や、谷木上に垂木やトラスの位置墨を出す作業も、水平面上ではなく、屋根の勾配面上においてメジャー等を用いて行われるため、設計図面に表記された水平投影寸法を一旦、勾配なりの寸法に換算しなければならず、精度とわかり易さが要求される作業であるにもかかわらず、実際には、複雑で間違い易い作業となっていた。
【０００４】
従って、本発明の目的は、本体屋根の屋根下地上の所定位置に、置き屋根を安全に且つ容易に構成することのできる住宅の棟違い部の屋根構造を提供することにある。
【０００５】
【課題を解決するための手段】
本発明は、１本の大棟を備えた本体屋根の屋根下地上に、該大棟と直交する方向の別の棟を備えた四面体からなる置き屋根が配設固定された構造を備えた屋根部を有する住宅の棟違い部の屋根構造において、前記四面体からなる置き屋根の３角形状の底面を構成する２本の谷木それぞれの一端を所定角度で互いに結合した２又形状の谷木フレーム、又は該谷木フレームにおける谷木それぞれの他端を１本の結合材の両端とそれぞれ結合して構成した所定の３角形状の谷木フレームを、該結合材を前記本体屋根の勾配に直交する方向に配して該本体屋根の所定位置に敷設固定し、敷設固定された前記谷木フレームを底面として前記置き屋根を形成してなり、前記四面体からなる前記置き屋根における正面部の前方に、該正面部を覆う別の屋根部が、該四面体の両側面部を構成する一対の置き屋根面と一体的に連設されており、該別の屋根部は、前記本体屋根を備えた家屋本体部に対して、家屋別体部の屋根を形成している、住宅の棟違い部の屋根構造を提供することにより、上記目的を達成したものである。

また、谷木フレーム５には、その敷設前に、図３に示すように、谷木５１を長さ方向に４等分する位置、谷木５２を長さ方向に４等分する位置、及び結合材５３における中点５３ｃに、それぞれ位置墨５７、５７・・・・が付され、谷木フレーム５の上に設置されるトラスや垂木の設置位置を明記してある。
【００１１】
次に、本実施形態の住宅の棟違い部の屋根構造を、置き屋根の施工手順について説明し、併せて、置き屋根の構成についても更に詳述する。
先ず、本体屋根３の骨組及び屋根下地を施工する。次に、本体屋根３の下り棟３２ｂにおける屋根下地上の所定位置に、予め谷木フレーム５の前記接合点５Ａの敷設固定位置（図示せず）を、ＣＡＤ図面情報を基に明記する。尚、ＣＡＤ図面情報とは、ＣＡＤを用いて作図された屋根伏図等における特定の線あるいは点の位置に関する電子情報をいう。

▲２▼本体屋根の下地上に谷木の敷設位置を出す作業が簡単になり、施工間違いを防止できる。
▲３▼谷木へ位置墨を出す作業を、工場等の水平面で行うことができる。
▲４▼垂木やトラスの位置を出す作業は、勾配なりに換算した寸法を水平面上で谷木フレームに墨出しするのみでよく、現場における換算間違いや墨出し間違いを防止できる。
▲５▼勾配面上での作業が減り、作業者の安全に寄与できる。
【００１４】
特に、前記実施形態においては、谷木フレーム５には、その敷設前に、一対の谷木５１、５２の所定位置に位置墨５７が付され、トラスや垂木の設置位置を明記してあるため、従来のように谷木を本体屋根に敷設固定した後、谷木に位置墨を出す必要がなく、置き屋根の施工が一層安全で容易となる。

【００１５】
また、本発明の住宅の棟違い部の屋根構造においては、前述した３角形状の谷木フレームに代えて、四面体からなる置き屋根の３角形状の底面を構成する２本の谷木それぞれの一端を所定角度で互いに結合した２又形状の谷木フレームを本体屋根の所定位置に敷設固定し、置き屋根を形成することもできる。この場合、２又形状の谷木フレームを本体屋根の所定位置に敷設固定し、本体屋根上において、該谷木フレームにおける谷木それぞれの他端を１本の結合材の両端とそれぞれ結合した後、該谷木フレーム上に骨組を形成し、置き屋根を形成する。
【００１６】
本発明の住宅の棟違い部の屋根構造は、前記実施形態に制限されることなく、本発明の趣旨を逸脱しない限り、例えば以下に示すように適宜変更が可能である。
本体屋根の形態は、切妻屋根や方形屋根等でもよく、家屋本体部の形態も前記実施形態に制限されない。
前記実施形態においては、置き屋根の正面部の前方に、該正面部を覆う別の屋根部が連設されているが、該別の屋根部の形態も前記実施形態に制限されず、別の屋根部の形態としては、置き屋根の一対の置き屋根面と一体的に連設した寄棟屋根や切妻屋根等でも良い。
【００１７】
谷木フレームを補強するための補強材の個数や配置等は、必要な強度が得られれば任意であり、また、谷木フレームの上に設置されるトラスや垂木等の骨組構成材の個数や配置等も、必要な強度が得られれば任意である。
本発明の住宅の棟違い部の屋根構造において、谷木フレームにトラスや垂木等の骨組構成材の設置位置を明記する際には、予め、ＣＡＤ図面情報を基に、谷木フレーム面に位置墨を自動で出す等の手段で、該設置位置を明記してもよい。また、骨組構成材の設置位置を示す位置墨等の個数や配置等は、置き屋根の骨組構成に対応して適宜設けられる。
更には、骨組構成材の設置位置を示す位置墨は、谷木フレーム面ではなく、本体屋根の下地である野地板表面に、予め手動あるいは自動で墨出ししておいてもよい。
【００１８】
置き屋根の骨組構造としては、図５に示すように、３角形状の谷木フレーム５上に、所定形状の板材を３角形状に結合してなるバレートラス６５ａ、６５ｂ、６５ｃ及び６５ｄを所定間隔で並置し、各バレートラス６５ａ、６５ｂ、６５ｃ及び６５ｄの先端を結合材で結合して、四面体が形成される骨組構造が挙げられる。ここで、各バレートラス６５ａ、６５ｂ、６５ｃ及び６５ｄは、相互に類似する２等辺３角形状である。尚、図５においては、各バレートラスを構成する板材同士を結合する結合材及び各バレートラスの先端を結合する結合材の図示を省略している。
前記実施形態においては、本体屋根の屋根下地に置き屋根を構成した後に、家屋別体部の屋根を形成する別の屋根部を構成しているが、本発明の住宅の棟違い部の屋根構造においては、本体屋根の屋根下地に置き屋根を構成する前に、該別の屋根部を構成していてもよい。
