Description

【０００１】
【発明の属する技術分野】
本発明は、出窓本体の下枠部分の強度の向上および施工性の向上を図った出窓に関する。
【０００２】
【従来の技術】
出窓は、建物の躯体にこれよりも屋外側へ張出した状態で出窓本体が取付けられるため、この出窓本体の下枠部分が出窓本体の荷重や出窓本体に取付けられる障子等の荷重により垂れ下がる傾向があり、その垂れ下がりによって障子の建付等に不具合が生じる場合がある。このような不具合を防止する目的で、出窓本体を支持するブラケットを建物の躯体における窓台に取付けることが従来より行われている（実開平５−８９７７４号公報参照）。
【０００３】
また、出窓の底部を補強するために、出窓の施工時に出窓本体の前方下枠と、窓台に設けられる後方下枠との間に補強骨材を係合させて架設し、屋内側に延出した補強骨材の後端部を窓台上に止着するようにした出窓も提案されている（実開平７−２３１８０号公報参照）。
【０００４】
【発明が解決しようとする課題】
しかしながら、上述した何れの出窓においても、その施工時にブラケットまたは補強骨材を窓台または下枠部分に取付けるように構成されているため、施工に手間がかかるという問題がある。また、このように手間のかかる上記ブラケットまたは補強骨材の取付けが現場サイドに任されているため、取付けを忘れたり、省略されたりする恐れがあり、このような場合には、出窓本体の下枠部分の強度を確保することが困難となり、下枠部分の垂れ下がりを招くことになる。
【０００５】
そこで、本発明の目的は、出窓本体の下枠部分の強度を確保することができると共に施工性の向上が図れる出窓を提供することにある。
【０００６】
【課題を解決するための手段】
上記目的を達成するために本発明のうち請求項１記載の出窓は、出窓本体の正面下枠と側面下枠からなる下枠部分の両端部間に掛け渡され、建物の躯体における窓台の屋外面に当接される窓台対向部材と、この窓台対向部材に設けられ、屋外側へ延出して上記窓台対向部材と対向する正面下枠に連結される先端部を有する補強ブラケットと、上記正面下枠および側面下枠には、これらで区画された形状のテーブル板の屋外側周縁部を差込んで保持するテーブル板保持溝が形成されていると共に、正面上枠，正面下枠，側面上枠，側面下枠，左右の方立及び縦枠を組立て、テーブル板保持溝、補強ブラケットおよび窓台対向部材により格子状に複数に区画されて略同一平面とされた上面部にテーブル板を載置したことを特徴とする。
【０００７】
請求項２記載の出窓は、
出窓本体の正面下枠と側面下枠からなる下枠部分の両端部間に掛け渡され、建物の躯体における窓台の屋外面に当接される窓台対向部材に、屋外側へ延出された先端部を有する補強ブラケットを予め設けておき、上記正面下枠および側面下枠には、これらで区画された形状のテーブル板の屋外側周縁部を差込んで保持するテーブル板保持溝が形成されていると共に、上記下枠部分の両端部間に上記窓台対向部材を掛け渡し、上記補強ブラケットの先端部を上記窓台対向部材と対向する正面下枠に連結して出窓本体を組立て、テーブル板保持溝、補強ブラケットおよび窓台対向部材により格子状に複数に区画されて略同一平面とされた上面部にテーブル板を載置したことを特徴とする。
【０００８】
請求項３記載の出窓は、出窓本体の正面下枠と側面下枠からなる下枠部分の両端部間に掛け渡され、建物の躯体における窓台の屋外面に当接される窓台対向部材に、屋外側へ延出された先端部を有する補強ブラケットと、出窓本体の底部を覆う底面板とを予め設けておき、上記正面下枠および側面下枠には、これらで区画された形状のテーブル板の屋外側周縁部を差込んで保持するテーブル板保持溝が形成されていると共に、上記下枠部分の両端部間に上記窓台対向部材を掛け渡し、上記補強ブラケットの先端部を上記窓台対向部材と対向する正面下枠に連結して出窓本体を組立て、テーブル板保持溝、補強ブラケットおよび窓台対向部材により格子状に複数に区画されて略同一平面とされた上面部にテーブル板を載置したことを特徴とする。
【００１０】
【実施の形態】
以下に、本発明の実施の形態を添付図面に基づいて詳述する。
【００１１】
図１ないし図２において、１は建物の躯体で、この躯体１には窓開口部２が設けられている。具体的には、この窓開口部２は躯体１における左右の柱３と、両柱３間に掛け渡された上下の枠材４，５とによって区画形成されている。上下の枠材４，５の外側は、複数の間柱６に支持されている。下枠材５は出窓の窓台を構成している。上記躯体１の屋外側には、窓開口部２に位置させて出窓が取付けられる。
【００１２】
この出窓は、正面部および両側面部を形成する平面断面形状が台形の出窓本体７を有し（図４参照）、この出窓本体７の上部には天板８や屋根９が取付けられ、出窓本体７の下部（下枠部分）にはテーブル板１０や底面板１１が設けられる。上記出窓本体７は、躯体１の柱３の屋外面にネジ１２等で固定される左右一対の縦枠１３と、これら縦枠１３と平行に屋外側に配置される左右一対の方立１４を有している。
【００１３】
両方立１４の上端部間及び下端部間には正面上枠１５及び正面下枠１６がそれぞれ掛け渡されて組立てられる。また、方立１４と縦枠１３の上端部間及び下端部間には側面上枠１７及び側面下枠１８がそれぞれ掛け渡されて組立てられる。このように出窓本体７は、これを構成する複数の枠材１３〜１８によって組立てられ、組立てられた出窓本体７の正面開口部には引き違い式の障子１９が取付けられ、側面開口部には嵌め殺し式の障子２０が取付けられる。出窓本体７を構成する枠材１３〜１８や障子１９，２０の框材は、アルミニウム合金の押出形材からなっている。
【００１４】
上記出窓本体７の正面下枠１６と側面下枠１８からなる下枠部分の両端部間、具体的には両縦枠１３の下端部間には、上記窓台５の屋外面に当接される窓台対向部材２１が正面下枠１６と平行に掛け渡され、図４に示すようにネジ２２で固定される。上記窓台対向部材２１には屋外側へ延出された先端部２３ａと屋内側へ延出された後端部２３ｂとを有する補強ブラケット２３が予め工場付けで固着されており、この補強ブラケット２３の先端部２３ａが上記窓台対向部材２１と対向する正面下枠１６に連結され、補強ブラケット２３の後端部２３ｂが上記窓台５の上部に載置されて固定具であるネジ２４，２５で固定されるようになっている。
【００１５】
上記窓台対向部材２１は、アルミニウム合金の押出形材からなり、横長の板状に形成されている。この窓台対向部材２１の上側には窓台５の上縁部に係止されて好ましくはネジ２６で固定されるフィン状の係止片２７と、上記補強ブラケット２３の上面に載置されるテーブル板１０の下面との間をシールする軟質樹脂製の気密材２８を取付けるための気密材取付片２９とが一体形成されている。この気密材取付片２９の上面は、上記補強ブラケット２３の上面よりも少し下方に位置されている。窓台対向部材２１は、水切りの機能も有している。主として上記窓台対向部材２１及び補強ブラケット２３により出窓本体７の下枠部分を補強する下枠補強材が構成される。
【００１６】
上記補強ブラケット２３は、図３ないし図５に示すように断面逆Ｕ字状に形成された剛性を有する金属材からなり、その基端部が上記窓台対向部材２１の屋外面に鍔２３ｃを介して当接されてリベット３０で固着されている。また、補強ブラケット２３の後端部２３ｂは、上記気密材取付片２９を貫通して屋内側へ延出されており、その延出部下面が鍔２３ｄを介して上記係止片２７上にリベット３１で固着されている。延出部下面には窓台５上に当接されてネジ２４で固定される鍔２３ｅも形成されている。補強ブラケット２３の本数は、出窓の幅により決定され、図示例では２本であるが、１本であってもよく、或いは３本以上複数本であってもよい。
【００１７】
補強ブラケット２３の先端部２３ａは、正面下枠１６に形成された溝３２に差込まれ、ネジ３３で固定される。このように出窓本体７の下枠部分に補強ブラケット２３を一体的に有する窓台対向部材２１が取付けられることにより、下枠部分の剛性ないし強度の向上が図れる。また、出窓本体７の両端部間（両縦枠間）の幅寸法を上記窓台対向部材２１によって規制することができる。
【００１８】
上記窓台対向部材２１は、出窓本体７等の荷重による下枠部分の垂れ下がり（変位量）を予め想定して上記補強ブラケット２３の先端部２３ａ側を水平よりも所定角度θ例えば０．７５゜上向きに傾斜させて上げておくために厚さ寸法ｔを下方に向って漸増させて形成されている。上記窓台対向部材２１は、その屋内面が窓台５の鉛直な屋外面に当接され、窓台対向部材２１の屋外面が上記補強ブラケット２３の傾斜角度と同じ角度で屋外側斜め下方に傾斜した傾斜面となるように厚さ寸法ｔを下方へ向って漸増させて形成されている。従って、これにより上記補強ブラケット２３の先端部２３ａ側が屋外側斜め上方へ上記所定の角度θで傾斜した状態となることから、出窓本体７等の荷重がかかったときに補強ブラケット２３の先端部２３ａ側が丁度水平になるように撓んで下枠部分を所定の位置に保持し、下枠部分の垂れ下がりを十分に防止できるようになっている。
【００１９】
上記正面下枠１６、側面下枠１８及び窓台対向部材２１の下端部には、これらで区画された形状の底面板１１の周縁部を差込んで保持する底面板保持溝３４，３５が形成されている。底面板１１は、金属板からなり、周縁部が底面板保持溝３４，３５に係合するように断面略Ｖ字状に折り返されている。
【００２０】
窓台対向部材２１の底面板保持溝３５を形成する上片３６には、底面板１１の折返し片が係合する抜け止め用の係合部３７が形成され、また上記補強ブラケット２３の先端部２３ａには、底面板１１の折り返し片が係合する係合溝３８が形成されており、これらにより予め底面板１１を補強ブラケット２３の下部に保持しておくことができ、組立施工性の向上が図れる。また、窓台対向部材２１と補強ブラケット２３の剛性によって底面板１１が補強されるため、底面板１１が運送中に変形しにくい。上記底面板１１の折り返し片には補強ブラケット２３の先端部を挟むように切欠部３９が設けられ、底面板１１が横にずれるのを防止している。上記底面板１１とテーブル板１０の間には、断熱材を取付けてることが可能である。
【００２１】
上記正面下枠１６および側面下枠１８には、これらで区画された形状のテーブル板１０の屋外側周縁部を差込んで保持するテーブル板保持溝４０が形成されている。このテーブル板保持溝４０は、フィン状の上片４１と下片４２により形成されており、その上片４１の縁部にはテーブル板１０の上面との間をシールする合成樹脂製の気密材４３が取付けられ、下片４２の縁部にはテーブル板１１を差込み易いようにテーパ４４が形成されている。
【００２２】
テーブル板１０は、出窓本体７を躯体１に取付けた後、屋内側から補強ブラケット２３の上面に沿ってスライドさせることにより上記テーブル板保持溝４０に差込まれ、簡単にセットできる。また、補強ブラケット２３を一体的に有する窓台対向部材２１により下枠部分の強度の向上を図ると共に、テーブル板保持溝４０、上記補強ブラケット２３および気密材取付片２９により格子状に複数に区画されて略同一平面とされた上面部にテーブル板１０を載置するようにして、テーブル板１０の支持強度の向上を図っているため、テーブル板１０を強度メンバーとする必要がなく、従ってテーブル板１０の薄形化が図れると共にテーブル板１０を必要以上に強固に固定する必要がない。
【００２３】
正面下枠１６と側面下枠１８の隣接するテーブル板保持溝４０の上片４１間を覆うために、側面下枠１８の上片４１には合成樹脂製のコーナーピース４５が取付けられ、このコーナーピース４５には方立１４に生じた結露を受ける結露受け４６が形成されている。上記コーナーピース４５にはテーブル板１０をネジ４７で固定するためのネジ孔（図示省略）が形成されており、テーブル板１０の前縁両側部を容易に且つ確実に固定できるようになっている。
【００２４】
また、テーブル板１０の屋内側後端部を固定するために、上記補強ブラケット２３の後端部２３ｂには引掛部４８が水平に突出形成されると共に、テーブル板１０にはその引掛部４８に係合する係合溝４９が形成されており、テーブル板１０後端部の持上がりを防止できるようになっている。また、出窓本体７の下枠部分の底面はほぼ平面に形成されており、組立工程や輸送時等に出窓本体７を平らな面に安定して載置可能になっている。
【００２５】
なお、図１ないし図２において、６０は上記窓開口部２の上部および両側の内周に取付けられた額縁、６１は両側の額縁６０に設けられた装飾用のケーシング、６２は両縦枠１３の上端部間に掛け渡されると共に上部の額縁６０にネジ止めされる天井見切材である。この天井見切材６２を含む出窓本体７の上部に天板８を介して屋根９が取付けられる。天板８と屋根９の間には断熱材６３が設けられることが好ましい。６４は縦枠１３に設けられた結露受けピース、６５は外壁材、６６は内壁材である。図３において、６７は出窓本体７の上枠部分の両端部間に掛け渡される天板見切り材で、出窓本体７を取付ける際に出窓本体７の上部の広がりを防止できる。
【００２６】
次に、以上の構成からなる出窓の組立て及び施工方法について述べる。側面下枠１８のコーナーピース４５や窓台対向部材２１の補強ブラケット２３は予め工場で取付けられており、出窓本体７の縦枠１３等の各構成部材、テーブル板１０や屋根９等は各場所毎に梱包される。出窓本体７の組立て、窓台対向部材２１の組付け等は工務店等で行われ、組立てられた出窓本体７や屋根９は建築現場まで輸送されて建物の躯体１の窓開口部２に取付けられる。
【００２７】
出窓本体７を躯体１の窓開口部２に取付ける場合には、なるべく荷重を軽くして取付作業を容易にするために、障子１９，２０や屋根９は後で取付けることが好ましいが、屋根９を含む出窓本体７の全てを組立ててから窓開口部２に取付けてもよい。出窓本体７を躯体１の窓開口部２に取付けるには、窓台対向部材２１の係止片２７を窓台５の上縁部に係止すると共に窓台対向部材２１の補強ブラケット２３の後端部２３ｂを窓台５上に載置してネジ２４，２５，２６で固定し、更に縦枠１３等を躯体１にネジ止めすればよい。
【００２８】
こうして出窓本体７を躯体１に取付けたなら、テーブル板１０を屋内側から補強ブラケット２３の上面に沿って屋外側へスライドさせ、テーブル板保持溝４０に差込むと共に、テーブル板１０後端部の係合溝４９を補強ブラケット２３後端部の引掛部４８に係合させ、テーブル板１０の前縁両側部をネジ４７で固定する。そして、出窓本体７に屋根９や障子１９，２０を取付ければよい。
【００２９】
このように上記出窓は、出窓本体７の下枠部分の両端部間に掛け渡され、建物の躯体１における窓台５の屋外面に当接される窓台対向部材２１と、この窓台対向部材２１に設けられ、屋外側へ延出して上記窓台対向部材２１と対向する正面下枠１６に連結される先端部２３ａと屋内側へ延出された後端部２３ｂとを有する補強ブラケット２３と、出窓本体７を構成する全ての枠材１３〜１８を組立て、上記補強ブラケット２３の後端部２３ｂを上記窓台５の上部に載置して上記出窓本体７を躯体１の窓開口部２に取付けることにより施工される。従って、出窓本体７の下枠部分の強度を十分に確保することができると共に、施工性の向上が図れる。
【００３０】
上記窓台対向部材２１には上記補強ブラケット２３が予め工場付けで固着されているため、手間がかからず、施工時に補強ブラケット２３の取付けを忘れたり、省略される恐れがなく、出窓本体７の下枠部分の強度を確保することができると共に、施工性の向上が図れる。また、窓台対向部材２１と補強ブラケット２３の剛性によって底面板１１が補強されるため、底面板１１が運送中に変形しにくい。更に、上記窓台対向部材２１が、これに基端部が当接された上記補強ブラケット２３の先端部２３ａを上記下枠部分の垂れ下がりを予め想定して上げておくために厚さ寸法ｔを下方へ向って漸増させて形成されているため、下枠部分の垂れ下がりを十分に防止することができ、障子１９，２０の建付性の維持および出窓の耐久性の向上が図れる。
【００３１】
以上、本発明の実施の形態を図面により詳述してきたが、本発明は上記実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲での種々の設計変更等が可能である。例えば、出窓本体７の平面断面形状としては、方形等であってもよい。また、窓台対向部材２１と底面板１１は一体に形成されていてもよい。
【００３２】
