【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。
