【発明の属する技術分野】
本発明は、住宅等の屋根に設置される換気棟に関する。
【０００２】
【従来の技術】
住宅等の屋根に設置される換気棟には、図７に示すように、屋根６１の棟部分に設けた屋根開口部６２の上方に、棟を挟む一対の屋根面間に跨るように設けられ、下部材６３と、下部材６３との間で排気通路６４を形成する中部材６５と、中部材６５との間で外気の通風路６６を形成する上部材６７とを備え、各下部材６３と中部材６５と上部材６７とが、一対の屋根面の傾斜に対応する一対の傾斜部を有するようにへの字状に屈曲され、例えば、下部材６３の中央部に排気口６３ａが設けられ、中部材６５の両端部に排気口６５ａが設けられたものがある。
【０００３】
この種の従来の換気棟は、同図に示すように、下部材６３と中部材６５とをボルトナット等の連結具６９で連結すると共に、釘等の固定具７０で、下部材６３を屋根面に固定し、上部材６７を連結板７１等を介してボルトナット、ビス等の締結具７３により中部材６５に連結固定するようにしていた（例えば、特許文献１）。

【発明が解決しようとする課題】
しかし、従来の換気棟では、上部材６７と中部材６５と下部材６３との３つの部材を、屋根下地と下部材６３、下部材６３と中部材６５、中部材６５と上部材６７を、それぞれ専用の連結具６９とビス等の締結具７３で止め付けており、各金具同士を直接連結しておらず、上中下の板金部材６７，６５，６３同士を順次連結している。従って、下部材６３と中部材６５との連結強度及び中部材６５と上部材６７との連結強度は、金具とビスとの連結強度ではなく、板金の引き裂き強度となり、風による振動やあおる力に弱くなった。
【０００６】
本発明は上記問題点に鑑み、風による振動やあおる力に強い換気棟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】
この技術的課題を解決するための本発明の技術的手段は、棟を挟む一対の屋根面４ａ，４ｂ間に跨るように取付られる下部材１３と、下部材１３の上方に配置される中部材１４と、中部材１４の上方に配置される上部材１５とを備えた換気棟において、
棟を挟む両側に、下部材１３と中部材１４とを連結する第１連結部材３７と、中部材１４と上部材１５とを連結する第２連結部材３８とが設けられ、第１連結部材３７と第２連結部材３８とが、締結具５５により互いに連結固定されている点にある。
【０００８】
また、本発明の他の技術的手段は、第１連結部材３７が、下部材１３と共に釘等の固定具５８により屋根面４ａ，４ｂに固定されている点にある。
また、本発明の他の技術的手段は、第１連結部材３７と第２連結部材３８とが中部材１４を挟んで締結具５５により締め付け固定されている点にある。

第１連結部材３７は、中部材１４の傾斜部１４ａ，１４ｂの下面に沿う上壁部４１と、上壁部４１から下方に突出した垂下部４２と、垂下部４２から屋根流れ方向に突出した下壁部４３と、下壁部４３から上方に突出した起立部４４とを有している。第２連結部材３８は、下壁部４７と、下壁部４７から上方に突出した起立部４８と、起立部４８の上端から屋根流れ方向に突出した上壁部４９と、上壁部４９から下方に突出した垂下部５０とを有している。
第１連結部材３７の垂下部４２が下部材１３の起立部２１に外側から接当されると共に、第１連結部材３７の下壁部４７が下部材１３の設置部２２に上側から重合され、第１連結部材３７の下壁部４７と、下部材１３の設置部２２とがリベット等の締結具５２により締結され、これにより、下部材１３と第１連結部材３７とが連結固定されている。第１連結部材３７の下壁部４３が、下部材１３の設置部２２を介して屋根面４ａ，４ｂに接当されている
第２連結部材３８の垂下部５０が中部材１４の起立部３１に外側から接当されると共に、第２連結部材３８の下壁部４７が中部材１４の傾斜部１４ａ，１４ｂに上側から重合され、第２連結部材３８の下壁部４７と、中部材１４の傾斜部１４ａ，１４ｂとがリベット等の締結具５３により締結され、第２連結部材３８の垂下部５０と、中部材１４の起立部３１とがリベット等の締結具５３により締結され、これにより、中部材１４と第２連結部材３８とが連結固定されている。第２連結部材３８の垂下部５０が、中部材１４の設置部３２を介して屋根面４ａ，４ｂに接当されている
第１連結部材３７の起立部４４と第２連結部材３８の垂下部５０の下半部とは、中部材１４の起立部３１を挟んで重合されて、ビス等の締付具５５により締結固定され、これにより、締付具５５によって第１連結部材３７と第２連結部材３８とが互いに連結固定されると共に、締付具５５によって中部材１４が第１連結部材３７及び第２連結部材３８に連結固定されている。第２連結部材３８の上壁部４９上に上部材１５の傾斜部１５ａ，１５ｂが載置されて、ビス等の締付具５６により締結され、これにより、上部材１５が第２連結部材３８に連結固定されている。また、第１連結部材３７は、下部材１５と共に釘等の固定具５８により、屋根面４ａ，４ｂに固定されている。
【００１４】
上記実施の形態によれば、換気棟１１を取り付ける場合、下部材１３に一対の第１連結部材３７を締結具５２により固定すると共に、中部材１４に一対の第２連結部材を締結具５３により固定しておき、まず、下部材１３を、防水材１６を介して屋根面４ａ，４ｂ上に載置し、釘等の固定具５８により、第１連結部材３７を下部材１３と共に屋根面４ａ，４ｂに固定する。この際、下部材１３の屈曲を容易に調整して、下部材１３の傾斜部１３ａ，１３ｂを屋根面４ａ，４の傾斜に簡単に合わせることができる。
【００１５】
その後、中部材１４を、設置部３２を介して屋根面４ａ，４ｂ上に載置すると共に、中部材１４の起立部３１を、第１連結部材３７の起立部４４に外側から接当させて、第１連結部材３７の起立部４４と第２連結部材３８の垂下部５０の下半部とを中部材１４の起立部３１を挟んで重合した状態にし、その後ビス等の締付具５５により第１連結部材３７の起立部４４と第２連結部材３８の垂下部５０の下半部とを締結固定する。この際にも、中部材１４の屈曲を容易に調整して、中部材１４の傾斜部１４ａ，１４ｂを屋根面４ａ，４ｂの傾斜に簡単に合わせることができる。
【００１６】
次に、上部材１５の各傾斜部１５ａ，１５ｂを、一対の第２連結部材３８の上壁部４９上に載置し、締結具５６により、第２連結部材３１の上壁部３２と上部材１５の傾斜部１５ａ，１５ｂとを締め付け固定すればよい。
この場合、下部材１３と第１連結部材３７とは、釘等の固定具５８により、屋根面４ａ，４ｂに固定され、中部材１４は第１連結部材３７を介して屋根面４ａ，４ｂに固定されるので、下部材１３及び中部材１４は、第１連結部材３７の連結強度によって支持されることになり、風による振動やあおる力に強くなり、屋根面４ａ，４ｂに、下部材１３及び中部材１４は強固に支持固定される。
【００１７】

【００１８】
また、換気棟１１の取付け後には、下部材１３と中部材１４との間に排気通路１７が形成され、上部材１５と中部材１４との間に通風路１８が形成され、屋根開口部７から排出された排気は、図１に実線の矢印ａで示す如く、下部材１３の排気口２４を通って、下部材１３と中部材１４との間の排気通路１７に入り、排気通路１７を通って、中部材１４の排気口４４から中部材１４と上部材１５との間の通風路１８に入り、上部材１５の折曲縁部２８下方から外部に排気される。また、外部からの空気は、図１に点線の矢印ｂで示す如く、上部材１５の一方の折曲縁部２８下方から上部材１５と中部材１４との間の通風路１８を通って上部材１５の他方の折曲縁部２８下方から外部に排出される。
【００１９】
図４〜６は他の実施の形態を示し、中部材１４の設置部３２が省略されると共に、下部材１３の設置部２２を屋根流れ方向の下側に大きく突出させている。下部材１３の一対の傾斜部１３ａ，１３ｂの中央部側に排気口２４が設けられ、中部材１４の一対の傾斜部１４ａ，１４ｂの外側部側に排気口３４が設けられている。
また、第１連結部材３７の起立部４４が省略され、第１連結部材３７は、上壁部４１と垂下部４２と下壁部４３とを有し、下部材１３の起立部２１と第１連結部材３７の垂下部４２とがリベット等の締結具５２により締め付け固定され、下部材１３の設置部２２と第１連結部材３７の下壁部４３とがリベット等に締結具５２により締め付け固定され、これにより、下部材４３と第１連結部材３７とが連結固定されている。第１連結部材３７の下壁部４３が、下部材１３の設置部２２を介して屋根面４ａ，４ｂに接当されている
第２連結部材３８の垂下部５２が中部材１４の起立部３１に外側から接当されると共に、第２連結部材３８の下壁部４７が中部材１４の傾斜部１４ａ，１４ｂに上側から重合され、第２連結部材３８の下壁部４７と、中部材１４の傾斜部１４ａ，１４ｂとが、リベット等の締結具５３により、邪魔板５９と共に締結され、第２連結部材３８の垂下部５０と、中部材１４の起立部３１とがリベット等の締結具５３により締結され、これにより、中部材１４と第２連結部材３８とが連結固定され、中部材１４及び第２連結部材３８に邪魔板５９が連結固定されている。第２連結部材３８の垂下部５０が、下部材１３の設置部２２を介して屋根面４ａ，４ｂに接当されている
第１連結部材３７の上壁部４１と第２連結部材３８の下壁部４７とは、中部材１４の傾斜部１４ａ，１４ｂと邪魔板５９とを挟んで重合されて、ビス等の締付具５５により締結固定され、これにより、締付具５５によって第１連結部材３７と第２連結部材３８とが互いに連結固定されると共に、締付具５５によって中部材１４が第１連結部材３７に連結されている。さらに、邪魔板５９が第１連結部材３７及び第２連結部材３８に連結固定されている。邪魔板５９は、下部材１３と中部材１４との間の外側部側に突出し、鈍角で二段に屈曲されて、下部材１３と中部材１４との間を排気通路１７を大きく迂回した形状にしている。
【００２０】
また、前記実施の形態の場合と同様に、第２連結部材３８の上壁部４９上に上部材１５の傾斜部１５ａ，１５ｂが載置されて、ビス等の締付具５６により締結され、これにより、上部材１５が第２連結部材３８に連結されている。また、第１連結部材３７は、下部材１５と共に釘等の固定具５８により、屋根面４ａ，４ｂに固定されている。
その他の点は前記実施の形態の場合と同様の構成であり、この実施の形態の場合も、下部材１３と第１連結部材３７とは、釘等の固定具５８により、屋根面４ａ，４ｂに固定され、中部材１４は第１連結部材３７を介して屋根面４ａ，４ｂに固定されるので、下部材１３及び中部材１４は、第１連結部材３７の連結強度によって支持されることになり、風による振動やあおる力に強くなり、屋根面４ａ，４ｂに、下部材１３及び中部材１４は強固に支持固定される。また、上部材１５は第２連部材３８及び第１連結部材３７を介して屋根面４ａ，４ｂに固定されるので、第２連結部材３８及び第１連結部材３７の連結強度によって支持されることとなり、風による振動やあおる力に強くなり、屋根面４ａ，４ｂに、上部材１５は強固に支持固定される。また、第１連結部材３７及び第２連結部材３８の一端部（下壁部４３，垂下部５０）が、下部材１３の設置部２２を介して屋根面４ａ，４ｂに接当しているため、積雪等よる上からの荷重に十分に耐え得るものとなる。
【００２１】
