Description

【０００１】
【発明の属する技術分野】
本発明は、建築物、構築物などの構造物の採光用庇、採光用天窓として、若しくは温室等の屋根として、等多目的に利用することができて、長年の経過によってシーリング材が劣化しても漏水しなくて雨仕舞いが著しく良好な採光用ガラス屋根に関するものである。
【０００２】
【従来の技術】
ガラス屋根において、隣り合うガラスパネルの端縁接合部から漏れる雨水を排出する提案は、例えば特開平６−２２９０７４号公報に記載されている。
前記従来技術は、熱溶着性の合成樹脂製で、上方が開口した断面形状を有する樋部材を、ガラスパネルの接合部の下方に設け、接合部の交差部分において各樋部材の端部同士を隙間なく突き合わせ、この突き合わせ部を溶着してなる構成である。
【０００３】
【発明が解決しようとする課題】
したがって、前記構成の従来技術では、建築現場で合成樹脂製の樋部材を突き合わせて溶着する手間が必要であり、また構造が複雑で現場での組み立て作業が著しく面倒である。
したがって、本発明は現場での作業をきわめて簡単にすることができ、しかも雨漏りがしないし、各部材を著しく強固に固定できるので強風に耐えることができるばかりでなく、長期間の使用に耐えることができるガラス屋根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】
前記目的を達成させるため、本発明の請求項１に記載した発明は、棟側の水上受枠部材と軒先側の水下受枠部材との間に複数本の垂木枠部材を平行に配設し、隣り合う垂木枠部材間に敷設するガラスパネルの棟側上縁部を前記水上受枠部材に設けた水上ガラス押え枠部材で支持するとともに、ガラスパネルの軒先側下縁部を前記水下受枠部材より軒先側に延在させ、前記ガラスパネルの側縁部を垂木枠部材の上面に設けた下側のガラス受枠部材と上側のガラス押え枠部材とで挟持して支持し、前記ガラス受枠部材には、左右のガラスパネルの側縁部から流入する水を受け止める第１ガイド溝部を左右に形成し、前記ガラス受枠部材とガラス押え枠部材との軒先側先端部を、前記水下受枠部材に設けた水下処理枠材で被着してなることを特徴とする。
【０００５】
また本発明の請求項２に記載した発明は、棟側の水上受枠部材と軒先側の水下受枠部材との間に複数本の垂木枠部材を平行に配設し、隣り合う垂木枠部材間に複数枚のガラスパネルを敷設して、棟側に位置するガラスパネルの棟側上縁部を前記水上受枠部材に設けた水上ガラス押え枠部材で支持するとともに、軒先側に位置するガラスパネルの軒先側下縁部を前記水下受枠部材より軒先側に延在させ、前記ガラスパネルの側縁部を垂木枠部材の上面に設けた下側のガラス受枠部材と上側のガラス押え枠部材とで挟持して支持し、前記ガラス受枠部材には、左右のガラスパネルの側縁部から流入する水を受け止める第１ガイド溝部を左右に形成し、前記ガラス受枠部材とガラス押え枠部材との軒先側先端部を、前記水下受枠部材に設けた水下処理枠材で被着し、水の流れ方向に隣り合うガラスパネルの接続部下側に受枠材を設け、前記受枠材の上面に設けた接続部ガラス受枠部材と上側の接続部ガラス押え枠部材とで前記ガラスパネルの接続部を止水処理し、前記接続部ガラス押え枠部材をガラスパネルの横幅より短くして左右に水の通過路を形成するとともに、前記接続部ガラス受枠部材に形成した水の受け溝部の端部を前記ガラス受枠部材の第１ガイド溝部に臨ませてなることを特徴とする。
【０００６】
【発明の実施の形態】
以下に本発明を図面に示す実施の態様に基づいて説明する。
図１は本発明の採光用ガラス屋根の第１実施例の平面図、図２は拡大して一部を断面とした斜視図、図３は棟側の縦断面図、図４は軒先側の縦断面図、図５は垂木枠部材の部分の縦断面図、図６は補強枠部の一部を断面とした斜視図、図７は第２実施例の軒先側の縦断面図、図８は本発明の第３実施例の縦断面図、図９は本発明の第４実施例の平面図、図１０は図９のＡ−Ａ線の断面図、図１１は図１０のＢ−Ｂ線の断面図、図１２は図１０のＣ−Ｃ線の断面図、図１３は図９のＤ−Ｄ断面図である。
【０００７】
本発明の第１実施例のガラス屋根ａは、棟側に設ける水上受枠部材１と、軒先側に設ける水下受枠部材２との間に、複数本の垂木枠部材３を平行に配設し、隣り合う垂木枠部材３、３の間にガラスパネルｇを敷設し、前記ガラスパネルｇの棟側上縁部を前記水上受枠部材１に設ける水上ガラス押え枠部材４で支持するとともに、ガラスパネルｇの軒先側下縁部を前記水下受枠部材２より軒先側に延在させ、前記ガラスパネルｇの側縁部を垂木枠部材３の上面に設ける下側のガラス受枠部材５と上側のガラス押え枠部材６とで挟持して支持した構成である。
【０００８】
前記水上受枠部材１は、図２、３で示すように、例えばアルミニウムの押し出し成形による長尺な縦長矩形状の中空枠体で、正面中央部と下面中央部に断面Ｃ字状に窪む第１受け溝部１１を設けるとともに、前後の表面上方に僅かに窪む第１嵌合凹部１２を長さ方向に沿って形成した構成である。
【０００９】
前記水下受枠部材２は、図２、４で示すように、前記水上受枠部材１と同様にアルミニウムの押し出し成形による長尺な縦長矩形状の中空枠体で、下面に前記第１受け溝部１１と同様の構成の第２受け溝部２１を設けるとともに、前記第１嵌合凹部１２と同一構成の第２嵌合凹部２２を前後の表面上方に長さ方向に沿って設け、さらに棟側の表面中央部分に位置するように排水溝部２３を設けてなる構成である。
【００１０】
前記垂木枠部材３は、図２、５で示すように、前記水上受枠部材１と同様にアルミニウムの押し出し成形による長尺な縦長矩形状の中空枠体で、左右の側面上方に前記第１嵌合凹部１２と同一構成の第３嵌合凹部３１を設けるとともに、上面の左右に、逆Ｌ字状の係止片３２を突設した構成である。
【００１１】
前記水上受枠部材１に取り付けてガラスパネルｇの棟側上縁部を支持する水上ガラス押え枠部材４は、図２、３で示すように縦部分４１の上縁に軒先側に延びる横向きの押え片４２を延在させ、前記縦部分４１の下方にクランク状に屈曲する嵌合部４３を設けてなる構成である。
【００１２】
前記垂木枠部材３の上面に取り付けてガラスパネルｇの側縁部を支持する前記ガラス受枠部材５は、図２、５で示すように、前記垂木枠部材３の左右の係止片３２間に装着される底面部５１の左右に、上面が開放する第１ガイド溝部５２を延在させ、前記底面部５１の上面左右に上端が鉤状となった係止フック片５３を直立状に設けるとともに、両係止フック片５３の間に茸状の直立部５４を設けてなる構成である。
【００１３】
また、前記ガラス受枠部材５の上面に被着固定する前記ガラス押え枠部材６は、図２、５で示すように、平板状の押え片６１の下面に、前記ガラス受枠部材５の係止フック片５３に係合する左右の係合フック片６２を下向きに延在させた構成である。
【００１４】
前記した構成の水上受枠部材１、水下受枠部材２，垂木枠部材３，水上ガラス押え枠部材４、ガラス受枠部材５及びガラス押え枠部材６を使用してガラス屋根ａを葺くのは以下のような工程である。
【００１５】
第１工程として、図３で示すように、予め水上受枠部材１の第１嵌合凹部１２に水上ガラス押え枠部材４の嵌合部４３を嵌め込み、タッピングねじｎにより固定して水上受枠部材１と水上ガラス押え枠部材とを一体化する。
【００１６】
そして、第２工程として、構造物の躯体ｋにアンカーボルト７１によって止着具７２を固着し、前記水上受枠部材１の第１受け溝部１１に頭部を装着して保持した固定ボルト７３を前記止着具７２に固定することによって、水上受枠部材１を支持する。
【００１７】
前記止着具７２は、前記アンカーボルト７１によって躯体ｋの表面に固定される第１止着具７４と、前記第１止着具７４に回動可能に連結されて水上受枠部材１の下面に固定される第２止着具７５とからなるので、第１止着具７４と第２止着具７５との回動状態により水上受枠部材１の角度（即ち屋根勾配）を自由に調節することができ、所望の角度に設定したら両端部を躯体に固定する。そして、第１止着具７４及び第２止着具７５の表面に鋸歯状のローレット部７６を形成し、また各ボルト７１、７３のワッシャーに前記ローレット部７６に噛合するローレット部を設けると、水上受枠部材１の上下位置、前後位置を正確に設定することができるし、経年の経過によってナットなどが仮に微小だけ緩んだとしても、風圧や積雪などの荷重により枠体全体が微動したりがたつくことがない。
【００１８】
第３工程として、前記水下受枠部材２を軒先側に固定するのであるが、水下受枠部材２は、構造物の軒先側に設ける梁材、桁材に固定して支持してもよいし、左右の端部を構造物の躯体に固定して支持するようにしてもよい。
【００１９】
前記のようにして、構造物の棟側に水上受枠部材１を、軒先側に水下受枠部材２を固定したら、第４工程として、両受枠部材１、２間に、複数本の垂木枠部材３を平行に設置する。垂木枠部材３の設置態様は、棟側においては図３で示すように上端縁を水上受枠部材１の表面上方に当接させ、当接部分における第１嵌合凹部１２と第３嵌合凹部３１との上下位置を一致させ、両嵌合凹部１２、３１の当接隅部にＬ字状の連結金具７７を嵌着し、連結金具７７の表面から通すタッピングねじｎを水上受枠部材１、垂木枠部材３の側面に打ち込んで固定する。
【００２０】
したがって、連結金具７７は両嵌合凹部１２、嵌合凹部３１の内部に強固に嵌着され、正確に位置が設定されるので、水上受枠部材１に対して垂木枠部材３が高精度の位置に、しかも強固に固定される。しかも、連結金具７７は、両嵌合凹部１２、３１に埋没状に嵌着されるのでシャーコッターとしての機能を有することになるので、負担する荷重（特に剪断荷重）が著しく軽減される。そのため、従来のように負担する荷重の大きさに対応するねじ（例えばＭ８程度の貫通ボルト）を選択して使用する必要がないし、小径のねじ（例えば４ミリ程度のタッピングねじ）を１本若しくは２本程度を連結金具から枠部材の側面に打ち込むだけで充分に耐えることができるので、使用するねじ等の材料の節約、作業の単純化、及び作業時間の短縮化を図ることができる。
【００２１】
次に、第５工程として、水上受枠部材１に固定された垂木枠部材３の軒先側の端部を、図４で示すように水下受枠部材２の棟側表面に当接させ、前記水上受枠部材１と同様にして、両枠部材の当接部の第２嵌合凹部２２と第３嵌合凹部３１との上下位置を一致させ、両嵌合凹部２２、３１の当接隅部にＬ字状の連結金具７７を装着し、連結金具７７の表面から通すタッピングねじｎを水下受枠部材２、垂木枠部材３に打ち込んで固定する。
【００２２】
したがって、垂木枠部材３の軒先側端部も水下受枠部材２に高精度で強固に固定されるので、水上受枠部材１と水下受枠部材２、及びその間の複数本の垂木枠部材３により、梯子状になる。
【００２３】
次に、第６工程として、各垂木枠部材３の上面にガラス受枠部材５を配置し、底面部５１を左右の係止片３２間に挿通して軒先側から棟側に摺動し、垂木受枠部材３の上面にガラス受枠部材５とセットする。この場合、ガラス受枠部材５の棟側上端は、前記第１工程における水上ガラス押え枠部材４の内部に挿着し、また軒先側下端は、図２、４で示すように、水下受枠部材２より軒先側の外部に延長させる。
【００２４】
次に、第７工程として、水上受枠部材１の上面、水下受枠部材２の上面、及びガラス受枠部材５の第１ガイド溝部５２にセットブロックｂを載置し、隣り合う垂木枠部材３、３間にガラスパネルｇを敷設し、ガラスパネルの棟側の上縁を水上受枠部材１のセットブロックｂに、軒先側の近傍を水下受枠部材２のセットブロックｂに、左右の側縁を第１ガイド溝部５２のセットブロックｂに、それぞれ受け止めさせる。
したがって、ガラスパネルｇは、棟側及び左右の側縁がセットブロックｂに支持されることになり、また左右の側縁が第１ガイド溝部５２までであるから、隣り合うガラスパネルｇの側縁に、左右の係止片３２の間隔程度の隙間が形成される。
【００２５】
第８工程として、ガラス受枠部材５の上面に沿ってガラス押え枠部材６を配置し、前記ガラスパネルｇの隙間内に左右の係合フック片６２を装着してガラス受枠部材５の係止フック片５３に係合させる。この場合、図５で示すように、ガラス押え枠部材６の上面から止着ねじ６３を係合フック片６２に沿い打ち込み、下端を直立部５４と係合フック片６２との間に嵌合させると、係合フック片６２が固定されるので係止フック片５３との係合が外れなくなる。
【００２６】
したがって、ガラスパネルｇの軒先側を除く３辺は、下面がセットブロックｂで支持され、棟側の上縁の上面は水上ガラス押え枠部材４の押え片４２で被われ、左右の側縁の上面がガラス押え枠部材６の押え片６１で被われることになる。
【００２７】
そして、第９工程として、水下受枠部材２から軒先側の外部に延長するガラス受枠部材５とガラス押え枠部材６とが重合する軒先側先端部に、水下処理枠材８を取り付ける。
【００２８】
前記水下処理枠材８は、縦断面がコ字状の軒先枠８１の下面部分を延長させ、その先端に下向きに屈曲する固定片８２を設けた構成で、前記固定片８２の上下長さは、前記水下受枠部材２の第２嵌合凹部２２に一致する。そして、前記軒先枠８１の下面先端には、水抜き孔８３を開設する。
【００２９】
したがって、前記固定片８２を水下受枠部材２の外側に位置する第２嵌合凹部２２に嵌着し、タッピングねじｎで固定すると、軒先枠８１が前記ガラス受枠部材５とガラス押え枠部材６とが重合する軒先側先端部に被着する状態になる。
【００３０】
前記第１工程から第９工程によって各部材が組み立てられ、またガラスパネルｇが左右に垂木枠部材間に敷設されることになる。
【００３１】
したがって、各枠部材とガラスパネルとの間から雨水が浸入するのを防止するため、シール受け材ｕとシーリング材ｓを設けて閉塞する。
【００３２】
具体的には、棟側においてはガラスパネルｇの棟側上面と水上ガラス押え枠部材４の押え片４２との間の間隔部、軒先側においてはガラスパネルｇの軒先側下面と水下受枠部材２の上面との間隔部及びガラスパネルｇの軒先部分の上面、下面と水下処理枠材８の間隔部、ガラスパネルｇの側縁上面とガラス押え枠部材６の押え片６１の下面との間隔部に、開放部の奥側にシール受け材ｕを設けてシーリング材ｓを充填する。
【００３３】
したがって、各枠部材とガラスパネルとの間隔から、雨水が浸入して屋根の下方に落下することがない。そして、長期間の経過により仮にシーリング材ｓが劣化して雨水が浸入する状態になったとしても、ガラスパネルの側縁においてはガラス受枠部材５の第１ガイド溝部５２を流下して水抜き孔８３から落下するので、屋根の下側に垂れ落ちることがない。また、棟側においてシーリング材ｓが劣化した場合、シーリング材ｓが収縮して押え片４２の下面とシーリング材ｓとの間に隙間が発生し、その部分から雨水が浸入する。しかしその雨水は、縦部分４１の表面から嵌合部４３の上端の上面部４６に流れ、傾斜下方側の端部から妻側の躯体に沿って流れ落ちるので特に悪影響をしない。また、軒先側においてシーリング材ｓが劣化した場合、室外側であるから特に悪影響を与えることがない。
【００３４】
なお、図３で示すように水上ガラス押え枠部材４の押え片４２上面に水受け片４４を設けるとともに、躯体ｋに水切り片４５を設けて前記水受け片４４の上方に位置させると、棟側の雨仕舞いが良好になる。
【００３５】
図６は、補強用として、前記水下処理枠材８を、隣り合う垂木枠部材３の中央部に位置させて、水下受枠部材２に固定した構成を示すものである。即ち、ガラス屋根ａの軒先側が開放していると、強風時に屋根下側に吹き込む風の圧力が大きいので、垂木枠部材３の間隔が捲り上がったり、破損することがある。
そこで、ガラスパネルｇの軒先側を前記水下処理枠材８で補強することにより、強風時に捲り上がったり破損するのを防止するのである。
【００３６】
図７は本発明の第２実施例を示すもので、水下受枠部材２の外面側に適宜の間隔で雨樋受け金具７８を設け、ガラス屋根ａの軒先に沿って雨樋７９を設けた構成である。この第２実施例によれば、軒先部から垂れ落ちる雨水は全て雨樋７９で受け止められるので、軒先部に壁面や開口部があって室内側と室外側とに仕切られている場合に有効である。
なお、図７において説明していない符号は、前記第１実施例の同一符号と同一の構成であるから具体的説明を省略する。
【００３７】
図８に示す本発明の第３実施例は、水上受枠部材１をコンクリートの棟木である躯体ｋに、また水下受枠部材２をコンクリートの梁材である躯体ｋに、それぞれ前記止着具７２を使用して固定した構成で、また水下処理枠材８’のコ字状軒先枠８１’を、下面より上面を長くすることにより、軒先部を水下受枠部材２のほぼ上方に位置させるようにした構成である。この第３実施例によれば、棟木及び梁材の躯体ｋの下側に壁面を設けてあって採光用天窓、温室などの建築物となり、雨仕舞いが良好になるし、軒先部が延長しない体裁の良い建築物を建築することができる。
なお、図８において説明していない符号は、前記第１実施例の同一符号と同一の構成であるから具体的説明を省略する。
【００３８】
図９から図１３までは本発明の第４実施例を示すもので、雨水の流れ方向に２枚のガラスパネルｇを接続した構成を示す。
即ち、前記垂木枠部材３に直交する方向のガラスパネルｇの接続部９の下方には、受枠部材９１を左右の垂木枠部材３間に掛け渡すようにして設け、前記受枠部材９１の上面には中空な矩形枠状の基台枠部材９２を、その上面に接続部ガラス受枠部材９３を設置し、接続部ガラス受枠部材９３の各端部を前記垂木枠部材３上のガラス受枠部材５とガラス押え枠部材６との間に挿着し、第１ガイド溝部５２の上方に位置させる（図１０）。
【００３９】
前記接続部ガラス受枠部材９３には長さ方向に直交する方向の中央部分に受け部９４を、その左右に第２ガイド溝部９５を有し、接続部９におけるガラスパネルｇの水下側の下縁部分、水上側の上縁部分をそれぞれ第２ガイド溝部９５に臨ませる（図１２）。
【００４０】
前記接続部ガラス受枠部材９３の左右端部の上面には、受け片９６を、受け部９４に載るようにして設置し、左右の両受け片９６の間には、中空な矩形枠状の支持枠部材９７を、受け部９４に載せてガラスパネルｇの上面より上方に突出するように設置する（図１２）。
【００４１】
そして、前記支持枠部材９７の上面には、平板状の接続部ガラス押え枠部材９８を、左右端部を前記支持枠部材９７より僅かに延長させて設け、左右の受け片９６の上面にはガラスパネルｇの接続部間隔を閉塞するようにしてシーリング材ｓを設けるとともに、接続部ガラス押え枠部材９８の四辺下面には、シール受け材ｕを介してシーリング材ｓを設ける（図１３）。
【００４２】
したがって、前記各接続部９には、左右の一部にガラスパネルｇより突出する接続部ガラス押え枠部材９８がなくて、下面がシーリング材ｓで閉塞された雨水の流路ｒが形成され、また中央部分に接続部ガラス押え枠部材９８とシーリング材ｓとにより雨水が堰き止められる堰部ｔが形成される。
【００４３】
なお、左右の垂木枠部材３と受枠部材９１との接続は、前記実施例の嵌合凹部と連結金具と同一の構成であり、受枠部材９１、基台枠部材９２、接続部ガラス受枠部材９３、受け片９６、支持枠部材９７、接続部ガラス押え枠部材９８などは、タッピングねじを使用して接触する部材に固定するものである。
【００４４】
本発明の第４実施例は、前記した構成であるから、屋根の表面の雨水は左右の流路ｒを伝わって水下側に流れ、軒先から流下したり雨樋に流れ込む。そして、仮にシーリング材ｓが劣化してシール機能が低下し、雨水が屋根下に漏れることがあったとしても、接続部ガラス受枠部材９３の第２ガイド溝部９５から第１ガイド溝部５２に流入するので、屋根下に垂れ落ちることがない。
なお、図９から図１３において、説明していない符号は前記第１実施例の同一符号と同一の構成であるから詳細な説明を省略する。
【００４５】
以上本発明を図面に示す実施例に基づいて説明したが、本発明は前記実施例に限定されるものではなく、特許請求の範囲に記載した構成を変更しない限り、どのようにでも実施することができる。例えば、止着具７２により設計段階で屋根勾配を自由に設定することができるし、軒先枠部材を、軒先側の補強を兼ねて長尺部材にすることもできる。
【００４６】
【発明の効果】
以上要するに、本発明によれば、棟側の水上受枠部材と軒先側の水下受枠部材との間に複数本の垂木枠部材を平行に配設し、隣り合う垂木枠部材間に敷設するガラスパネルの棟側上縁部を前記水上受枠部材に設けた水上ガラス押え枠部材で支持し、前記ガラスパネルの側縁部を垂木枠部材の上面に設けた下側のガラス受枠部材と上側のガラス押え枠部材とで挟持して支持し、前記ガラス受枠部材には、左右のガラスパネルの側縁部から流入する水を受け止めるガイド溝部を左右に形成し、前記ガラス受枠部材とガラス押え枠部材との軒先側先端部を、前記水下受枠部材に設けた水下処理枠材で被着してなることを特徴とする。
【００４７】
したがって、少ないパーツできわめて簡単に、短時間で屋根葺き作業をすることができるし、確実に雨仕舞いをすることができる。そして、各パーツを機能的に固定しているので強度が著しく高く、台風などの強い自然条件に耐えることができるばかりでなく、長期間の使用に耐えることができる。
【００４８】
また、軒先部分を水下受枠部材より軒先側の外部に延長させたり、軒先部分に雨樋を設けることにより、軒先側がオープンであっても雨水の吹き込みが少なくなり、特に建築物の庇としての機能を高めることができる。
【００４９】
また、枠部材に長さ方向に沿う嵌合凹部を設け、枠部材の当接部分における当接隅部に連結金具を嵌着し、連結金具の表面から通すねじを枠部材の側面に打ち込んで固定することにより、両枠部材が高精度の位置に、強固に固定されるばかりでなく、連結金具は両嵌合凹部に埋没状に嵌着されるのでシャーコッターとしての機能を有することになり、負担する荷重（特に剪断荷重）が著しく軽減されて従来のように負担する荷重の大きさに対応するねじを選択して使用する必要がないし、強度の少ないねじを１乃至数本を連結金具から枠部材の側面に打ち込むだけで充分に耐えることができるので、使用するねじ等の材料の節約、作業の単純化、及び作業時間の短縮化を図ることができる。

BACKGROUND OF THE INVENTION
INDUSTRIAL APPLICABILITY The present invention can be used for various purposes such as a lighting rod for a structure such as a building or a structure, a skylight for lighting, or a roof of a greenhouse, etc. Even if the sealing material deteriorates over the years. The invention relates to a daylighting glass roof that does not leak and has very good rain.
[0002]
[Prior art]
A proposal for discharging rainwater leaking from the edge joint portion between adjacent glass panels in a glass roof is described in, for example, Japanese Patent Application Laid-Open No. 6-229074.
The prior art is made of a heat-sealable synthetic resin and has a gutter member having a cross-sectional shape with an open top provided below the joint portion of the glass panel. It is a structure formed by abutting without any gap and welding the butted portion.
[0003]
