【０００１】
【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１４に示すように、屋根の棟部分に設けた屋根開口部７１の上方に、棟を挟む一対の屋根面間に跨るように換気棟板７２が設けられ、該換気棟板７２は、一対の屋根面に沿うように山形状に形成された一対の傾斜部７３を有し、一対の傾斜部７３に排気孔７６が設けられ、換気棟板７２の排気孔７６の下方に、棟板受け７７が設けられ、図１４に示すように、換気棟板７２の傾斜部７３と棟板受け７７との間にスペーサ部材８１が設けられ、スペーサ部材８１を貫通する釘等の固定具８２により、傾斜部７３と棟板受け７７とを屋根面に固定するようにしたものがある。
【０００３】
この種の従来の換気棟は、図１５に示すように、スペーサ部材８１の上端部に、上方突出する環状突起８５が設けられ、スペーサ部材８１の下端部に環状溝８６が設けられている。
また、換気棟板７２の固定用の上取付孔８８の開口縁部（バーリング突起）８９が、スペーサ部材８１の環状突起８５に外嵌され、棟板受け７７の固定用の下取付孔９１の開口縁部（バーリング突起）９２が、スペーサ部材８１の環状溝８６に嵌合されている。
【０００４】
そして、釘等の固定具８２が、シール用キャップ９３、固定用の取付孔８８，９１及びスペーサ部材８１に挿通されて、屋根面に打ち付けられ、これにより、釘等の固定具８２によって、換気棟板７２の傾斜部７３と棟板受け７７との間にスペーサ部材８１を介在した状態で、釘等の固定具８２により、傾斜部７３と棟板受け７７とが屋根面に固定されていた（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、スペーサ部材８１によって、換気棟板７２と棟板受け７７とを互いに離間しないように締結するようになっておらず、このため、釘等の固定具８２により、換気棟板７２及び棟板受け７７とを屋根面に固定する前に、換気棟板７２と棟板受け７７とをリベット、ビス等の締結具９５，９６によって互いに離間しないように締結しておく必要があった。従って、スペーサ部材８１とは別個に換気棟板７２と棟板受け７７とを締結するためのリベット、ビス等の締結具９５，９６が必要になるし、換気棟板７２及び棟板受け７７に対してスペーサ部材８１を組み込む他に、換気棟板７２と棟板受け７７とをリベット、ビス等の締結具９５，９６によって締結する作業が必要となり、部品点数が多くなるし、組み付け工数も増えることになり、経済的に不利になった。
【０００７】
本発明は上記問題点に鑑み、換気棟板と棟板受けとを締結するためのリベット、ビス等の締結具が少なくて済むようにして、部品点数を減らすと共に、組み付け工数を減らして、製造費用が安上がりになるようにしたものである。
【０００８】
【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、換気棟板１３の下方に、棟板受け１４が設けられ、換気棟板１３と棟板受け１４との間に、スペーサ部材４２が設けられ、換気棟板１３の上取付孔２４及び棟板受け１４の下取付孔３４を介してスペーサ部材４２を貫通する釘等の固定具４３により、換気棟板１３と棟板受け１４とを屋根面４ａ，４ｂに固定するようにした換気棟において、
スペーサ部材４２の上端部に、上取付孔２４の開口縁部３９を係止する上係止部４７が設けられ、スペーサ部材４２の下端部に、下取付孔３４の開口縁部４０を係止する下係止部４８が設けられ、上係止部４７で上取付孔２４の開口縁部３９を係止すると共に、下係止部４８で下取付孔３４の開口縁部４０を係止することにより、スペーサ部材４２で換気棟板１３と棟板受け１４とが互いに離間しないように締結され、
前記上係止部４７は、上取付孔２４の開口縁部３９が上下移動不能に係止されるように、スペーサ部材４２の上端部外周面に没入形成した環状溝により構成され、スペーサ部材４２の上係止部４７より上方に、上取付孔２４に下側から挿通可能となるように上方に向けて徐々に小径となるテーパー部４９が設けられ、前記下係止部４８は、下取付孔３４に挿通不能となるようにスペーサ部材４２の下端部に設けたフランジ部により構成され、スペーサ部材４２の下係止部４８より上方側は、下取付孔３４に下側から挿通可能とされている点にある。
【００１２】
【発明の実施の形態】
以下、本発明を図示の実施の形態に従って説明する。
図１において、１は棟木、２は垂木、３は野地板で、棟木１と垂木２とで組み上げた屋根４の骨組上に張り付けられている。野地板３の上面に、アスファルトルーフィング等の防水シート５が敷かれ、その上にストレート瓦等の屋根材６が葺かれている。
屋根４の棟部分に、野地板３及び屋根材６等を切り欠いてなる屋根開口部７が設けられ、この屋根開口部７の上方に、棟を挟む一対の屋根面４ａ，４ｂ間に跨るように換気棟１１が設けられている。なお、８は屋根開口部７に対応して設けた水切り部材である。
【００１３】
図１〜図５において、前記換気棟１１は、板金製の換気棟板１３と板金製の左右一対の棟板受け１４とを備えている。
換気棟板１３は、一対の屋根面４ａ，４ｂに沿うように山形状に形成された一対の傾斜部１５と、一対の傾斜部１５の外側端から下方に突出された一対の起立部１６と、一対の起立部１６の下端から屋根面４ａ，４ｂに添うように屋根流れ方向に突出された一対の設置部１７とを有している。換気棟板１３の設置部１７の外端部に、下側にＵ字状に折り返してなる折り返し部１９が設けられている。
【００１４】
図４に示すように、一対の傾斜部１５の外側部側（軒側）に、複数（図例では２個）の排気孔２０が屋根流れ方向に連続するように設けられ、この連続する複数（２個）ずつの換気孔２０が、棟方向に間隔をおいて複数設けられている。各換気孔２０は、傾斜部１５に風避け片２１を下方に切り起こすことにより形成され、風避け片２１は円弧状に湾曲形成されている。傾斜部１５の換気孔２０間に、固定用の上取付孔２４が棟方向に間隔をおいて複数個設けられている。図１〜図３に示すように、一対の傾斜部１５の棟側の下面に、防露材１８が設けられている。
【００１５】
図１〜図３及び図５に示すように、棟板受け１４は、一対の傾斜部１５の外側部側（軒側）の下方にそれぞれ配置され、防水材２２を介して屋根面４ａ，４ｂ上に設置されている。各棟板受け１４は、傾斜部１５の排気孔２０に対向する受け板部２７と、受け板部２７の内側端から上方に突出した起立部２８と、起立部２８の上端から屋根流れ方向に突出した接当部２９と、接当部２９の外側端から下方に突出した垂下部３０と、垂下部３０の下端から屋根流れ方向に突出した突出部３１とを有する。また、棟板受け１４の受け板部２７の外側端側に、換気棟板１３の設置部１７の下面側に沿うように、屋根流れ方向に突出した突出板部３２が設けられている。
【００１６】
図２、図３及び図５に示すように、棟板受け１４の起立部２８に排気口２６が設けられ、棟板受け１４の受け板部２７に、固定用の下取付孔３４が棟方向に間隔をおいて複数個設けられ、この固定用の下取付孔３４は、傾斜部１５の固定用の上取付孔２４に対応している。
接当部２９が換気棟板１３の傾斜部１５に下側から接当されている。また、突出板部３２の突出端部が、換気棟板１３のＵ字状の折り返し部１９に下側から圧接され、これにより、棟板受け１４上の水が突出板部３２を伝わって折り返し部１９から屋根面４ａ，４ｂ上に排出されるようになっている。棟板受け１４の突出板部３２よりも屋根流れ方向の上側に、排水孔３７が設けられている。
【００１７】
換気棟板１３の固定用の上取付孔２４の開口縁部３９が、バーリングにより上方に突出した環状に形成され、棟板受け１４の固定用の下取付孔３４の開口縁部４０が、バーリングにより上方に突出した環状に形成されている。
換気棟板１３の傾斜部１５と棟板受け１４との間にスペーサ部材４２が設けられ、スペーサ部材４２を貫通する釘、ねじ釘、ビス等の固定具４３により、傾斜部１５と棟板受け１４とが屋根面４ａ，４ｂに固定されている。
図２、図３及び図６〜図８に示すように、スペーサ部材４２は、ゴムや弾性を有する合成樹脂等により円筒状に形成され、スペーサ部材４２の軸心方向に、釘等の固定具４３を挿通する挿通孔４４が形成され、スペーサ部材４２の上端部に、上取付孔２４の開口縁部３９を係止する上係止部４７が設けられ、スペーサ部材４２の下端部に、下取付孔３４の開口縁部４０を係止する下係止部４８が設けられている。
【００１８】
上係止部４７は、スペーサ部材４２の上端部外周面に没入形成した環状溝により構成され、上係止部４７に上取付孔２４の開口縁部３９が外嵌されて、上係止部４７で上取付孔２４の開口縁部２４を上下移動不能に係止している。下係止部４８は、スペーサ部材４２の下端部に設けたフランジ部により構成され、下係止部４８の外径は下取付孔３４の孔径より大に形成され、下係止部４８は下取付孔３４に挿通不能になっており、下取付孔３４の開口縁部４０がスペーサ部材４２の下係止部４８の上方に外嵌されて、下係止部４８で下取付孔３４の開口縁部４０を下方移動を規制するように係止している。
【００１９】
スペーサ部材４２の上係止部４７より上方に、上方に向けて徐々に小径となるテーパー部４９が設けられ、テーパー部４９は上取付孔２４に下側から挿通可能とされている。スペーサ部材４２の下係止部４８より上方側は、その外径が下取付孔３４の孔径と略同一に形成され、下取付孔３４に挿通可能とされている。
上記の如く上係止部４８で上取付孔２４の開口縁部３９を上下移動不能となるように係止すると共に、下係止部４８で下取付孔３４の開口縁部４０を下方移動を規制するように係止することにより、スペーサ部材４２で換気棟板１３と棟板受け１４とを互いに離間しないように締結している。接当部２９の傾斜部１５への接当及び突出板部３２の突出端部の折り返し部１９への圧接により、換気棟板１３と棟板受け１４との近接方向への移動が規制され、これにより、換気棟板１３と棟板受け１４とが相対移動不能に固定されている。
【００２０】
スペーサ部材４２に防水材２２が貼り付けられ、スペーサ部材４２は防水材２２を介して屋根面４ａ，４ｂ上に配置され、ねじ釘、釘等の固定具４３が固定用の上取付孔２４、スペーサ部材４２及び下取付孔３４に挿通されて、屋根面４ａ，４ｂに打ち付けられ、これにより、釘等の固定具４３によって、換気棟板１３の傾斜部１５と棟板受け１４の受け板部２７との間にスペーサ部材４２を介在した状態で、釘等の固定具４３により、傾斜部１５と受け板部２７とが屋根面４ａ，４ｂに固定されている。
【００２１】
上記実施の形態によれば、換気棟１１を組み立てる場合、例えば、一対の棟板受け１４を、換気棟板１３の下側から、一対の傾斜部１５の軒側の下方にそれぞれ配置して、棟板受け１４の接当部２９を換気棟板１３の傾斜部１５に下側から接当させ、また、突出板部３２の突出端部を、換気棟板１３の折り返し部１９に下側から圧接し、この状態で、スペーサ部材４２を、棟受け１４の下側から下取付孔３４に挿入した後、さらにスペーサ部材４２のテーパー部４９を、換気棟板１３の上取付孔２４に挿入すればよく、上取付孔２４の開口縁部３９が上係止部４７に外嵌されて、開口縁部３９が上係止部４７に上下移動不能に係止される。また、同時に、下取付孔３４の開口縁部４０がスペーサ部材４２の下係止部４８の上方に外嵌して、開口縁部４０が下係止部４８に下方移動が規制されるように係止される。その結果、スペーサ部材４２によって、換気棟板１３と一対の棟板受け１４とが互いに離間しないように簡単に締結される。
【００２２】
従って、換気棟板１３及び棟板受け１４とを屋根面４ａ，４ｂに固定する前等に、換気棟板１３と棟板受け１４とをリベット、ビス等の締結具によって互いに離間しないように締結する必要がなくなり、又は締結する箇所を減少させることができる。従って、スペーサ部材４２とは別個に換気棟板１３と棟板受け１４とを締結するためのリベット、ビス等の締結具を不要乃至減少させることができ、換気棟板１３と棟板受け１４とをリベット、ビス等の締結具によって締結する作業をなくし乃至減少させることができ、部品点数が少なくなるし、組み付け工数も少なくなり、製造費用が安上がりになって、経済的に有利になる。
【００２３】
そして、屋根面４ａ，４ｂへの換気棟１１の取付は、棟板受け１４を、防水材２２を介して屋根面４ａ，４ｂ上に載置し、ねじ釘、釘等の固定具４３を、固定用の取付孔２４，３４及びスペーサ部材４２に挿通して、屋根面４ａ，４ｂに打ち付け、これにより、釘等の固定具４３によって、換気棟板１３の傾斜部１５と棟板受け１４の受け板部２７との間にスペーサ部材４２を介在した状態で、釘等の固定具４３により、傾斜部１５と受け板部２７とを屋根面４ａ，４ｂに固定すればよい。
【００２４】
換気棟１１の取付け後には、屋根開口部７から排出された排気は、図１に矢印ａで示す如く、棟板受け１４の排気口２６を通って、換気棟板１３と棟板受け１４との間に入り、換気棟板１３の排気孔２０から外部に排気される。そして、排気孔２０から棟板受け１４上に侵入した雨水等の水は、突出板部３２を伝わって、まず、排水孔３７から屋根面４ａ，４ｂ上に排出され、排水孔３７がオーバーフローしても、残った水は、折り返し部１９側から屋根面４ａ，４ｂ上に排出される。しかも、棟板受け１４と屋根面４ａ，４ｂとの間に防水材２２が介在されているため、棟板受け１４と屋根面４ａ，４ｂとの間に排水路を確保することができる。従って、棟板受け１４上に侵入した水を、屋根面４ａ，４ｂ上にスムーズに排水できる。
【００２５】
図９は他の実施形態を示し、スペーサ部材４２の上係止部４７に、ワッシャー（リング）５０を外嵌し、上取付孔２４の開口縁部３９を上係止部４７のワッシャー５０より下方に外嵌して、開口縁部３９の上端をワッシャー５０に接当させるようにしたものである。ワッシャー５０は、スペーサ部材４２と同質のゴム系の材料であるゴム、合成樹脂等により構成され、又は金属その他により構成され、ワッシャー５０の外径は、スペーサ部材４２のテーパー部４９よりも大に形成されている。
【００２６】
この場合、スペーサ部材４２を換気棟板１３及び棟板受け１４に装着して換気棟板１３と棟板受け１４とを締結するには、ワッシャー５０を取り外したスペーサ部材４２を、棟板受け１４の下側から下取付孔３４に挿入した後、さらにスペーサ部材４２のテーパー部４９を、換気棟板１３の上取付孔２４に挿入し、その後、換気棟板１３の上取付孔２４から突出したテーパー部４９にワッシャー５０を嵌めて上係止部４８にワッシャー５０を外嵌し、ワッシャー５０を開口縁部３９に上側から接当させればよく、この場合、上取付孔２４の開口縁部３９の内径が、スペーサ部材４２のテーパー部４９の外径と略同等又はやや大であっても、上取付孔２４の開口縁部３９をワッシャー５０を介して上係止部４８に上方移動不能に確実に係止させることができ、上取付孔２４の開口縁部３９の内径を、スペーサ部材４２のテーパー部４９の外径と略同等又はやや大に形成することにより、スペーサ部材４２を換気棟板１３及び棟板受け１４に装着する際に、スペーサ部材４２のテーパー部４９を、換気棟板１３の上取付孔２４に楽に挿入することができ、スペーサ部材４２の換気棟板１３及び棟板受け１４への装着がより簡単で、かつ、上係止部４７の上取付孔２４の開口縁部３９の係止がより確実にできるようになる。
【００２７】
図１０及び図１１は他の実施形態を示し、下係止部４８は、スペーサ部材４２の下端部外周面に没入形成した環状溝により構成され、下係止部４８に下取付孔３４の開口縁部４０が外嵌されて、下係止部４８で下取付孔３４の開口縁部４０を上下移動不能に係止している。スペーサ部材４２の下係止部４８より下方に、上取付孔２４に上側から挿通可能となるように下方に向けて徐々に小径となるテーパー部５１が設けられている。また、棟板受け１４の下面に上取付孔２４を塞ぐように防水材２２が貼り付けられ、棟板受け１４は防水材２２を介して屋根面４ａ，４ｂ上に配置されている。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、上係止部４７は、スペーサ部材４２の上端部外周面に没入形成した環状溝により構成され、スペーサ部材４２の上係止部４７より上方に、上取付孔２４に下側から挿通可能となるように上方に向けて徐々に小径となるテーパー部４９が設けられている。
【００２８】
上記実施の形態によれば、換気棟１１を組み立てる場合、スペーサ部材４２を換気棟板１３と棟板受け１４との間に配置し、スペーサ部材４２のテーパー部４９を、下側から換気棟板１３の上取付孔２４に挿入して、上取付孔２４の開口縁部３９を上係止部４７に外嵌することにより、開口縁部３９を上係止部４７に上下移動不能に係止する。また、スペーサ部材４２のテーパー部５１を、上側から棟板受け１４の下取付孔３４に挿入して、下取付孔３４の開口縁部４０を下係止部４８に外嵌することにより、開口縁部４０を上係止部４８に上下移動不能に係止すればよく、これにより、スペーサ部材４２によって、換気棟板１３と一対の棟板受け１４とが互いに離間しないように簡単に締結され、棟板受け１４の接当部２９が換気棟板１３の傾斜部１５に下側から接当すると共に、突出板部３２の突出端部が、換気棟板１３の折り返し部１９に下側から圧接した状態に保持される。
【００２９】
従って、この場合も、スペーサ部材４２とは別個に換気棟板１３と棟板受け１４とを締結するためのリベット、ビス等の締結具を不要乃至減少させることができ、換気棟板１３と棟板受け１４とをリベット、ビス等の締結具によって締結する作業をなくし乃至減少させることができ、部品点数が少なくなるし、組み付け工数も少なくなり、製造費用が安上がりになって、経済的に有利になる。
図１２は他の実施の形態を示し、棟板受け１４の突出板部３２の突出端部を、換気棟板１３の折り返し部１９に嵌合させるようにしたものである。その他の点は前記図１〜図８、図９、図１０及び図１１の実施の形態の場合と同様の構成である。
【００３０】
なお、前記図１〜図８、図９、図１０及び図１１の実施の形態の場合、図２に２点鎖線で示すように、棟板受け１４の受け板部２７にＬ字状等の邪魔板５５をリベット等の締結具５６により締結し、垂下部３０に突出した突出部３１を省略するようにしてもよい。
図１３は他の実施の形態を示し、邪魔板５８をスペーサ部材４２によって挟み込むようにしたもので、邪魔板５８は、一対の起立部５９，６０と、一対の起立部５９，６０の上端間を連結する天板部６１と、棟側の起立部５９の下端から棟側に突出した設置部６２と、軒側の起立部６０の下端から軒側に突出した設置部６３と、該設置部６３から斜め上方に突出した傾斜突出部６４とを有し、一対の起立部５９，６０に通気口６５が設けられ、邪魔板５８の天板部６１に取付孔６６が設けられ、スペーサ部材４２の上係止部４７に取付孔６６の開口縁部が外嵌されている。また、換気棟板１３の起立部１６に排気口６７が設けられると共に、棟側に切り起こし形成した傾斜片６８が設けられている。その他の点は前記図１〜図８の実施の形態の場合と同様の構成である。
【００３１】
上記実施の形態によれば、スペーサ部材４２によって、換気棟板１３と一対の棟板受け１４とが互いに離間しないように簡単に締結されると共に、スペーサ部材４２によって、邪魔板５８が換気棟板１３と棟板受け１４との間に簡単に挟持固定される。そして、換気棟１１の取付け後には、屋根開口部７から排出された排気は、図１３に矢印ａで示す如く、棟板受け１４の排気口２６を通って、換気棟板１３と棟板受け１４との間に入り、邪魔板５８の通気口６５通った後、傾斜突出部６４の上方を通って、換気棟板１３の排気口６７から外部に排気される。
【００３２】
なお、前記実施の形態の場合、換気棟板１３の固定用の上取付孔２４の開口縁部３９が、バーリングにより上方に突出した環状に形成され、棟板受け１４の固定用の下取付孔３４の開口縁部４０が、バーリングにより上方に突出した環状に形成されているが、上取付孔２４の開口縁部３９及び下取付孔３４の開口縁部４０は、上方に突出した環状のものに限定されず、例えば、単に換気棟板１３又は棟板受け１４に上取付孔２４又は上取付孔３４を開口したままの環状のものであってもよい。
【００３３】
【発明の効果】
本発明によれば、換気棟板１３と棟板受け１４とを締結するためのリベット、ビス等の締結具が不要乃至少なくて済むようになり、このため、部品点数を減らすと共に組み付け工数を減らすことができ、製造費用が安上がりになる。
