Description

【０００１】
【発明の属する技術分野】
本発明は、建物の躯体から突出して設けられる出窓を構成する出窓ユニットおよび出窓ユニットの施工方法に関する。
【０００２】
【背景の技術】
一般に、出窓を設ける場合には、その出窓に独立した屋根が設けられることが多い。しかし、出窓に独立した屋根を設けることは、構造が複雑になるために施工に手間がかかり、出窓の施工性の向上が求められている。そのような課題に対し、特開平１０−３０６６５６号公報に記載の技術では、出窓を建物の軒先部に近い高さに達する位置に設け、建物の屋根の軒先部の樋カバーを出窓の屋根に兼用する構成にして対応している。
【０００３】
【発明が解決しようとする課題】
上記従来の技術には次のような課題があった。
特開平１０−３０６６５６号公報に記載の技術では、出窓に独立した屋根を設けるかわりに、出窓を建物の軒先部に近い高さに達する位置に設ける構成となっており、出窓の設置場所が限られる。
本発明は上記課題を鑑みてなされるものであり、屋根を独立に設ける出窓の建築現場での施工を簡略化することができる出窓ユニットおよび出窓ユニットの施工方法を提供することを目的とする。
【０００４】
【課題を解決するための手段】
上記課題に対し、請求項１の発明は、例えば図１、図３、図４、図５、図７に示すように、躯体１より外方に突出して設けられる出窓２を構成する出窓ユニットにおいて、
躯体１に取り付けられるとともに、出窓２に取り付ける窓枠であるサッシ枠２５の寸法に合わせて、屋根パネル８と床パネル９と側壁パネル１０，１０とによって矩形枠に組まれてなる出窓本体３と、
出窓本体３の上面部を覆う出窓屋根本体４６と、該出窓屋根本体４６の先端縁部に連続して形成されるとともに、自身の軒先部４１側に位置する出窓本体３の前面および自身の側面部４２，４２側に位置する出窓本体３の左右両側面とを覆う側壁部４７と、を有する部材であり、かつ前記出窓本体３の上部に取り付けられる出窓屋根部品４と、
前記出窓本体３に取り付けられるとともに、前記出窓屋根部品４の軒先部４１側に設けられる係合部４３と係合し、該出窓屋根部品４を出窓本体３に係合するための係合部５１が形成された受け材５とを備え、
前記出窓屋根部品４の軒先部４１側は出窓本体３の前面部において前記受け材５に係合され、
前記出窓屋根部品４の側面部４２，４２側は前記出窓本体３の側面に貼設された外装材６，６表面に当接されており、
前記出窓屋根部品４の側壁部４７の上端部には、該出窓屋根部品４の軒先部４１側から両側面部４２，４２側に連続するとともに外方に開口する溝４５が設けられており、
前記出窓屋根部品４は、前記溝４５から打ち込まれる釘１２等によって前記出窓本体３に固定されており、
前記躯体１に当接する前記出窓屋根部品４の基端部４４の裏面と、前記躯体１に当接する前記出窓本体３の基端部の上面との間には調整材７が設けられており、
前記出窓本体３下端部には下端水切材１７が出窓本体３の下端縁部に沿って設けられ、
前記下端水切材１７は、複数の取付部材１８を介して前記出窓本体３の下端縁部に取り付けられており、
前記取付部材１８は、前記下端水切材１７または出窓本体３の下端縁部に所定間隔で複数取り付けられていることを特徴としている。
【０００５】
請求項１の発明によれば、前記出窓本体３の前面部には受け材５が設けられ、前記出窓屋根部品４の軒先部４１は前記受け材５に係合されるので、出窓屋根部品４を出窓本体３に容易に係止できる。この際、出窓屋根部品４の側面部４２，４２は、前記出窓本体３の外装材６，６の表面に当接しているので、出窓屋根部品４の上下動が可能であり、前記出窓屋根部品４を前記受け材５に係合させる作業が容易に行える。よって、前記出窓屋根部品４を前記出窓本体３に容易に取り付けることができ、施工作業が軽減できる。
また、前記躯体１に当接する前記出窓屋根部品４の基端部４４の裏面と、前記躯体１に当接する前記出窓本体３の基端部の上面との間には調整材７が設けられているので、出窓屋根部品４を安定的に支持し、前記出窓本体３および躯体１への出窓屋根部品４の取り付けを容易に行える。また、出窓屋根部品４上部から加わる力に対する補強材としての効果を奏し、例えば、施工時に作業者が前記出窓屋根部品４に乗った場合にも、該出窓屋根部品４が所定の取付位置から下方にずれることを防ぐ。
また、前記出窓本体３下端部には下端水切材１７が出窓本体３の下端縁部に沿って設けられているので、躯体１より突出していることにより雨がかかりやすい出窓２において、出窓２より下方の壁面に雨水等が伝わって壁面が汚れたり、浸水することを防ぐことができる。また、前記下端水切材１７は、複数の取付部材１８を介して前記出窓本体３の下端縁部に取り付けられており、前記取付部材１８は、前記下端水切材１７または出窓本体３の下端縁部に所定間隔で複数取り付けられているので、下端水切材１７の取付位置がずれたり歪んだりすることがない。よって、下端水切材１７の取り付け作業を容易かつ正確に行うことができる。
【０００６】
出窓本体３は、出窓２の主要部を構成する部材であり、例えば、出窓２に取り付ける窓枠に合わせて複数のパネルによって枠が形成されるものがある。なお、その枠の表面には外装材６が設けられる場合がある。
【０００７】
出窓屋根部品４は、前記出窓本体３の上面部を覆う出窓屋根を形成する部品であり、出窓２の外観上の装飾効果と庇の機能を果たすものであり、例えば、傾斜屋根の形状を有するものや、陸屋根の形状を有するものがある。
【０００９】
調整材７は、例えば、長尺な角材であり、外装材の端材からなり、長尺な辺が出窓２の基端部に沿うようにして設けられるものである。
【００１３】
請求項２の発明は、請求項１に記載の出窓ユニットにおいて、
前記外装材６は、該出窓本体３の側面部全面を覆うようにして取り付けられることを特徴としている。
【００１４】
請求項２の発明によれば、前記外装材６は、該出窓本体３の側面部全面を覆うようにして取り付けられるので、図５に示すように、出窓屋根部品４が外装材６の上端部を覆う構成となり、雨水等が外装材６より内側に入ることがない。よって、出窓本体３への浸水をより確実に防ぐことができる。さらに、出窓屋根部品４と前記出窓本体３の接合部における防水の為のコーキングの作業を簡略化でき、施工作業が軽減される。また、前記外装材６は前記出窓本体３の側面部の下端まで覆っているので、出窓本体３下端部の内部への雨水等の浸水も防ぐことができる。
【００１５】
請求項３の発明は、請求項１または２に記載の出窓ユニットの施工方法において、
まず、前記出窓本体３を前記躯体１に取り付け、
次に、前記出窓屋根部品４を前記出窓本体３に前記出窓屋根部品４の側面部４２，４２が前記外装材６，６表面に当接するようにして覆い、
次に、前記出窓屋根部品４を該出窓屋根部品４の軒先部４１において、前記受け材５に係合させることを特徴としている。
【００１６】
請求項３の発明によれば、まず、前記出窓本体３が前記躯体１に取り付けられ、次に、前記出窓屋根部品４を前記出窓本体３に前記出窓屋根部品４の側面部４２，４２が前記外装材６，６に当接するようにして覆うので、前記出窓屋根部品４を前記出窓本体３に被せれば適切な取付位置に容易に誘導できる。また、その次に、前記出窓屋根部品４をその軒先部４１において、前記受け材５に係合させるので、出窓２の軒先部において、出窓屋根部品４を受け材５に係合させるだけで前記出窓屋根部品４が容易に取り付けられる。この際、出窓屋根部品４の側面部４２，４２は、前記出窓本体３の外装材６，６表面に当接しているだけなので、出窓屋根部品４の上下動が可能であり、前記出窓屋根部品４を前記受け材５に係合させる作業が容易に行える。これによって、屋根を独立に設ける出窓２の建築現場での施工を簡略化することができる。
【００１７】
【発明の実施の形態】
以下、図面を参照して本発明に係る出窓ユニットについて説明する。図３は本発明の出窓ユニットの実施の形態の一例を示す分解斜視図である。図３において、符号３は出窓本体、符号４は出窓屋根部品、符号５は受け材、符号６は外装材、符号１７は下端水切材であり、これらによって出窓ユニットの主要部が構成されている。
【００１８】
出窓本体３は、図２の出窓本体３の斜視図、図４および図５の出窓ユニットの上端部断面図に示すように、出窓２に取り付ける窓枠の寸法に合わせて、屋根パネル８と床パネル９と側壁パネル１０，１０とによって矩形枠に組まれている。
この矩形枠の前面側には、４本の角材からなる枠体１１が取り付けられている。
この枠体１１の前面上端部には合板からなる横胴縁１９が枠体１１上部に沿って貼設され、さらにその表面には外装材６が貼設されている。屋根パネル８上面に貼設された合板２１の表面には耐水シート２２が貼設され、この耐水シート２２は出窓本体３の前面上端部に設けられた横胴縁１９と出窓本体３の枠体１１との間に挟まれて前面上部の枠体１１の端部まで貼設されている。出窓本体３の側面には縦胴縁１５，１５が貼設され、さらにその表面には外装材６が側壁パネル１０，１０全面に貼設されている。そして、出窓本体３の前面部と側面部との接合部の出隅部分には、さらに外装材６の出隅役物２０が貼設されている。
【００１９】
出窓屋根部品４は、図３に示すように、前記出窓本体３の屋根パネル８を覆う面積を有し、出窓本体３の前面の縁部に向かって下方に傾斜する前面傾斜部４６ａと両側の側面の縁部に向かって下方に傾斜する側方傾斜部４６ｂ，４６ｂとで構成される出窓屋根本体４６と、該出窓屋根本体４６の先端縁部に連続して形成された側壁部４７とを鋼板で成形してなる部材である。また、図４および図５に示すように、側壁部４７は、前記出窓屋根本体４６の縁部から連続して側面を形成し、その上端部には外方に開口する溝４５が設けられている。該溝４５の下方は外方へ向けて突出している。そして、その突出部分のさらに下方では内側に直角に折り曲げられて水平な下端面を形成し、さらに上方へ向けて垂直に折り曲げられているが、その端部は前記出窓屋根部品４の軒先部４１と側面部４２，４２とで構成が異なる。軒先部４１では出窓２の内側方向に鈎状に突出する係合部４３が設けられるのに対し、側面部４２，４２では、端部がそのまま上方に向かって垂直に延びている形状となっている。
【００２０】
なお、出窓屋根本体４６の前面傾斜部４６ａの裏面には、前記前面傾斜部４６ａを補強するための合板１４が貼設されている。さらに、外装材の端材からなる長尺な角材である調整材７が前記合板１４の基端部側の端部に沿って設けられている。
【００２１】
受け材５は、図４に示すように、鋼板からなる断面略Ｊ字状の形状の部材であり、水平方向にコ字状に開口する溝と上方に開口する略Ｕ字状の溝とが連続して垂直に向き合い、略Ｕ字状の溝側の端部は、溝の内側方向に鋭角に曲折して係合部５１を形成している。この受け材５は前記出窓本体３の上端部は上端前面の横胴縁１９に当接しており、枠体１１に取り付けられている。なお、前記受け材５の下端背面と前記枠体１１との間に設けられる隙間Ｓはサッシ枠２５が挿入される溝となる。
【００２２】
外装材６は、出窓本体３の側面および前面を覆うように取り付けられる部材であり、防火性等を有する板状の素材を用い、意匠性を高める模様が形成されている。なお、前記外装材６は、横胴縁１９，１９あるいは縦胴縁１５，１５に貼設される。
【００２３】
下端水切材１７は、図３、図６および図７に示すように、出窓下端の縁部三方を囲むように成形された一つの部材からなる。その断面は上方が開口した溝状をなし、溝の前面側の端部は内側上方に傾斜するように延在した後、上端部は出窓本体３の壁面に沿うように上下方向に延びている。他方、溝の背面側の上端部は背面側に垂直に突出し、出窓本体３下面に沿うように延びている。
【００２４】
また、図６，図７および図８に示すように、取付部材１８は、前記下端水切材１７を正確にかつ容易に取り付けるための補助部材であり、二平面が直交してＬ字状をなし、平面部には釘１２を打ち込む釘穴が設けられている。この取付部材１８を前記下端水切材１７の内側に、所定間隔で複数設けることによって、前記下端水切材１７の取付位置を誘導し、取付位置の歪みを防ぐことができるようになっている。
【００２５】
次に、本実施の形態の出窓ユニットの施工方法について説明する。まず、予め工場にて形成された出窓本体３を躯体１を構成する壁面に取り付ける。このとき、図３に示すように、コーチスクリュー２３，２３を所定の位置に、躯体を構成する壁パネル１の壁面の裏面から挿通する。出窓本体３と壁パネル（躯体）１との当接面側の側壁パネル１０には、前記コーチスクリュー２３，２３が螺合される図示しない挿入孔が左右に取り付けられており、前記コーチスクリュー２３，２３を螺合させて出窓本体３を躯体１に取り付け、接着剤および釘（図示せず）にて固定する。
【００２６】
次に、出窓屋根部品４を出窓本体３に取り付ける。前記出窓屋根部品４を前記出窓本体３の上方から該出窓本体３の両端部と出窓屋根部品４の側面部４２，４４２の内側とが接合する位置で嵌合するように出窓本体３の上面に覆い被せる。
続いて、出窓本体３の前面部に取り付けられている受け材５の係合部５１と前記出窓屋根部品４の軒先部４１の係合部４３とが当接する位置まで、出窓屋根部品４を基端部４４側に押し込み、その位置で、出窓屋根部品４を上方に持ち上げながら、さらに押し込み前記受け材５に前記出窓屋根部品４の係合部４３を係合させる。このとき、前記出窓屋根部品４の基端部４４の裏面には前記調整材７が設けられているので、該出窓屋根部品４の上面の傾斜角度によって、出窓屋根部品４の基端部４４が所定位置から下方にずれることがなく、容易に取り付けることができる。次いで、出窓屋根部品４の溝４５に所定間隔で設けられた釘穴（図示せず）に、外方から釘１２を打ち込み、出窓屋根部品４を出窓本体３に固定する。
【００２７】
なお、出窓屋根部品４を出窓本体３に固定した後、前記出窓屋根部品４の基端部４４には、図３および図５に示すように、該出窓屋根部品４の前記出窓屋根本体４６の側方傾斜部４６ｂと、側面の凹凸部分を覆うカバー４８が取り付けられる。このとき、前記カバー４８と出窓屋根部品４の側面部４２，４２との間に生じる隙間には固着材１６が取り付けられる。このカバー４８によって、出窓屋根部品４の基端部４４を覆うので、壁パネル（躯体）１の外装材２４を、出窓屋根部品４の基端部４４側の端部の形状に合わせて切断する必要がなく、基端部における壁パネル（躯体）１の外装材２４の取り付けを容易に行うことができる。さらに、出窓本体３に当接しているだけである出窓屋根部品４の側面部４２，４２を補強し、該出窓屋根部品４の側面部４２，４２の浮きを防ぐ効果を奏する。
【００２８】
次いで、図７および図８に示すように、予め前記下端水切材１７の内側の所定位置に貼設された９個の取付部材１８を挟むようにして下端水切材１７を取り付け、外方から前記下端水切材１７および取付部材１８に設けられた釘穴を通して、出窓本体３の下端部に釘１２で打ち付けて固定する。次に、出窓本体３下端側に予め貼設されている横胴縁１９に外装材６を取り付ける。よって、出窓本体３の前面側の前記下端水切材１７と取付部材１８とは外装材６と出窓本体３との隙間に取り付けられることとなる。下端水切材１７をこのような構成で取り付けることによって、前記下端水切材１７と取付部材１８との接合面が外装材６に覆われて外部に露出せず、下端水切材１７の内部に雨水等が浸水することがない。
【００２９】
このようにして出窓ユニットの取り付けを終えたら、前記出窓屋根部品４の基端部４４と躯体１との接合部にシール材１３を貼り付けたり、出窓屋根部品４の側面４２，４２の各接合部に防水等の為にコーキングを施す等、全体の仕上げ処理を適宜行い施工を終了する。
【００３０】
上記実施の形態の例によれば、前記出窓屋根部品４の両側面部が出窓本体３の側壁パネル１０，１０の全面に設けられた外装材６に当接するようにして、出窓本体３の上部を覆っているので、出窓屋根部品４を容易に取り付けられる。また、その前面部を前記受け材５に係合する時に左右にずれることがない。よって、出窓本体３に出窓屋根部品４を容易に取り付けることができる。
【００３１】
なお、図５に二点鎖線で示すように、本発明の実施の形態と異なり、例えば、出窓本体３の側壁パネル１０，１０にも係合部を備えた受け材３０を設けた場合、側壁パネル１０，１０に取り付けた縦胴縁１５，１５および外装材６は、図中Ｌの位置で上部を切断し、前記受け材３０の下端面に当接する構成となる。そして、その当接部における浸水を防ぐために、符号３１に示す位置にコーキングを行う必要がある。一方、本願発明にかかる実施の形態の例によれば、前記出窓屋根部品４が、出窓本体３の外装材６の上端部も含めて覆う構成となっているので、前記出窓屋根部品４にかかった雨水等が、外装材６上端部から入ることがなく、出窓本体３内部に浸水することを防ぐことができる。このような構成によって、外装材６と出窓屋根部品４との当接面におけるコーキングの箇所を減らすことが可能となり、施工作業が軽減される。
【００３２】
また、前記下端水切材１７の内側に取り付けられた取付部材１８の角部の内側と前記出窓本体３の下端の角部とが当接するので、前記取付部材１８によって、下端水切材１７の取付位置が誘導され、容易かつ正確に前記下端水切材１７を取り付けることができる。
【００３３】
このように、上記出窓ユニットの例によれば、設置位置の制約を受けることなく出窓の屋根を独立に設ける出窓を容易に施工することができる。
【００３４】
なお、本実施の形態の例では、出窓本体３の形状を矩形としたが、これに限定するものではなく、例えば、側面が内側方向に傾斜している形状等、要は、出窓２に設けられる窓の形状に沿うものであればよい。また、出窓屋根部品４は鋼板製としたが、これに限定するものではなく、要は耐水性を有するものであればよい。また、出窓ユニットを取り付ける躯体１を壁パネルとしたが、これに限定するものではなく、一般の工法で施工された躯体の壁面などでもよく、要は躯体を構成する壁面に出窓２が取り付け可能な構成であればよい。また、受け材５の形状も実施の形態の一例であり、前記出窓屋根部品４を係合する係合部５１を有するものであればよい。
【００３５】
また、取付部材１８を前記下端水切材１７の内側の前記出窓本体３と当接する位置に設けたが、これに限定するものではない。例えば、取付部材１８を前記出窓本体３の枠体１１の下端部に所定間隔で複数設けることとしてもよく、要は、前記下端水切材１７と前記出窓本体３の下端部との間に取付部材１８を介して前記下端水切材１７が前記出窓本体３の下端縁部に取り付けられるものであればよい。
【００３６】
【発明の効果】
請求項１の発明によれば、前記出窓本体に設けられた受け材によって、前記出窓屋根部品は前記受け材に係合されるので、出窓屋根部品を出窓本体に容易に装着できる。この際、出窓屋根部品の側面部は、前記出窓本体の外装材に当接しているので、出窓屋根部品の上下動が可能となり、前記出窓屋根部品を前記受け材に係合させる作業が容易に行える。よって、前記出窓屋根部品を前記出窓本体に容易に取り付けることができ、施工作業が軽減できる。なお、前記出窓屋根部品の側面部が当接するのは前記外装材表面であるので、前記出窓屋根部品にかかった雨水等が、外装材によって防水され、出窓本体内部に浸水することを防ぐことができる。
また、前記躯体に当接する前記出窓屋根部品の基端部の裏面と、前記躯体に当接する前記出窓本体の基端部の上面との間に設けられた調整材によって、出窓屋根部品を安定的に支持し、前記出窓本体および躯体への出窓屋根部品の取り付けを容易に行える。また、出窓屋根部品上部から加わる力に対する補強材としての効果を奏し、該出窓屋根部品が所定の取付位置から下方にずれることがない。
また、前記出窓本体下端部には下端水切材が設けられているので、出窓より下方の壁面に雨水等が伝わり、壁面が汚れたり、浸水することを防ぐことができる。また、前記下端水切材は、複数の取付部材を介して前記出窓本体の下端縁部に取り付けられており、前記取付部材は、前記下端水切材または出窓本体の下端縁部に所定間隔で複数取り付けられているので、出窓本体への取付位置を容易に知ることができるとともに、下端水切材の取付位置がずれたり歪んだりすることがない。よって、下端水切材の取り付け作業を容易かつ正確に行うことができる。
【００３９】
請求項２の発明によれば、請求項１と同様の効果を得ることができるのはもちろんのこと、出窓屋根部品が外装材の上端部を覆う構成となり、雨水等が外装材より内側に入ることがない。よって、出窓本体への浸水をより確実に防ぐことができる。さらに、出窓屋根部品と前記出窓本体の接合部における防水の為のコーキングの作業を簡略化でき、施工作業が軽減される。また、前記外装材は前記出窓本体の側面部の下端まで覆っているので、出窓本体下端部への雨水等の浸水も防ぐことができる。
【００４０】
請求項３の発明によれば、請求項１または２と同様の効果を得ることができるのはもちろんのこと、前記出窓ユニットの施工方法によって、前記出窓屋根部品を前記出窓本体に被せれば適切な取付位置に容易に誘導できる。また、出窓の軒先部において、出窓屋根部品を外装材に係合させるだけで前記出窓屋根部品が容易に取り付けられる。また出窓屋根部品を受け材に係合する際、出窓屋根部品の上下動が可能であるので、前記出窓屋根部品を前記受け材に係合させる作業が容易に行える。よって、屋根を独立に設ける出窓の建築現場での施工を簡略化することができる。
