Description

【０００１】
【発明の属する技術分野】
本発明は、ガラス板に孔を明けずコーナー目地部を支持金具で締付挟持して支持するガラス板の支持金具、及び支持構造並びに施工方法に関する。
【０００２】
【従来の技術】
ガラス板の取付工法としては、各種の工法が知られており、並設した複数枚の面ガラスの縦目地部にリブガラスを立設させたガラスリブ工法、あるいは、サッシフレームを表に出さず構造用シーリング材でガラスを接着固定するＳＳＧ工法等の他、フレ−ムレスなガラススクリ−ンを構成する工法としては、ガラス板の四隅に設けた穿孔部を支持金具で支持する点支持工法や、ガラス板間の縦横の目地部を利用してガラス板を金具で挟持して支持する点支持工法等が現在良く知られており、近年注目されている。
【０００３】
前記ガラスに孔明けするタイプの点支持工法は、ガラス板の四隅部に穿設部を設け、立設する構造支柱等に固着のロッド等にＸ字状やＨ字状に延びるアームを備えた支持金具を取り付け、該アーム先端に設けた支持部材によってガラス板のコーナー部を支持するものである。
【０００４】
また、ガラス板の四隅部に孔を明けないでガラス板を支持する構造として、例えば、特開平９−３１７０７２号公報には、面一に上下左右に配設された４枚の矩形の板状部材のなす十字目地部の上側の左右の板状部材を、支持棒を介在させて外部支持部材及び内部支持部材により挟持して支持する板状部材支持構造において、上側の左右の板状部材は、上記十字目地部の近傍において、それぞれ別々の支持棒により、それぞれ別々の載置部材を介在させて支持されており、かつ載置部材は外部支持部材に対して回動可能に取り付けられている板状部材支持構造が開示されている。
【０００５】
【発明が解決しようとする課題】
前記リブガラス板を用いてガラススクリーンを形成する場合においては、通常ガラス板１枚分の高さまでに限定され、ガラス板を横方向に並設するのみであったので、大面積のガラススクリーンを形成するのは困難である。
【０００６】
また、前記ガラスの隅部に孔明けするタイプの点支持工法では、ガラス板を縦横に複数枚並設できるので、大面積のガラススクリーンを形成できるが、ガラス板の四隅に精度良く孔明け加工を必要とするものであった。
【０００７】
一方、ガラス板に孔を明けずにガラス板の十字状目地部を支持する構造として、前記特開平９−３１７０７２号公報に示されるものや図７で示した支持構造を始めとして殆どのものが、４枚のガラス板をすべて納めるまでは別な手段でガラス板を保持したりし、その後で、前面側から締付金具等を装着させていたため、手間が掛かるものであったり、人手で支えればガラス板が落下したりする危険性があり、危険が伴う作業であるという問題点があった。
【０００８】
【課題を解決するための手段】
本発明は、上記問題点の解決を図る、すなわち大面積のガラススクリーンを形成する場合に、ガラス板に孔を明けずにガラス板の支持を確実として、重量物であるガラス板の自重や面外方向の荷重等に対しても強度を低下させることがなく、ガラス板を嵌め込む前に前面側の支持金具を取付けすることができ、しかも別途支持しなくてもが支持不要で、取り付けたガラス板が落下することがなく、作業性が良く、作業中の落下等もなく、安全に取付施工することができ、地震等による層間変位の発生によるガラス板のロッキングによってガラス板が傾動しても、支持金具のガラス板の支持部もガラス板の挙動に追従可能であり、ガラス板を破損させないようにするものである。
【０００９】
すなわち、本発明は、上下左右に並設し立設する複数枚のガラス板の各下端コーナー突き合わせ部をガラス受部材で支持し、かつ前後両面より前面側金具と裏面側金具との螺合によって締付支持するガラス板の支持金具において、前記ガラス受部材は裏面側金具にて支持され、前面側金具が１／４円以上、半円未満迄の切欠部を有する前面板材と、該前面板材の中心に固着し裏面板材の雌ネジ部と螺合するボルト部と、前面板材の円弧部と外接螺合する前面カバー材とからなり、前面板材の取付後に切欠部よりガラス板を取付可能にしたことを特徴とするガラス板の支持金具である。
【００１０】
あるいは、本発明は、ガラス板の下端コーナー部を支持する前記ガラス受部材は、並設したガラス板間の十字状目地部中心に挿通したヒンジ機構を有し、該ヒンジ機構はヒンジ部の環状体の外周面に固着させた一対の支持板を有し、ガラス板の突き合わせコーナー部の裏面側に介在させる前記裏面側金具は、裏面板材とその中心に固着し前記ガラス受部材のヒンジ部の環状体に内接する筒状部とからなり、前面側金具前記切欠部を有する前面板材と、該前面板材が、該前面板材の中心に固着し裏面板材の雌ネジと螺合するボルト部と、前面板材の円弧部と外接し螺合する前面カバー材とからなり、ガラス板取付前に前面板材を取付可能にしたことを特徴とする上述のガラス板の支持金具である。
【００１１】
あるいはまた、本発明は、前記裏面板材に配設した支持ピンは、左右の支持板の下面の裏面側金具側の端部近傍を当接支持し、ガラス板の揺動によっても当接しない長さとしたことを特徴とする上述のガラス板の支持金具である。
【００１２】
さらに、本発明は、上述の支持金具を用いて、上下左右に並設し立設する複数枚のガラス板の各下端コーナー突き合わせ部をガラス受部材で支持し、かつガラス板の両面より前面側金具と裏面側金具との螺合によって締付支持するガラス板の支持構造において、前記ガラス受部材は裏面側金具に固着または支持され、ガラス板のコーナー突き合わせ部の前面より１／４円以上１／２円未満の切欠部を有した前面板材に垂設したボルト部を、構造体に連結固着した裏面側金具の裏面板材と螺合させてガラス板を締付支持し、前記切欠部を有した前面板材の外周部に前面カバー材を螺合させ、ガラス受部材のガラス板下端との当接部に硬質樹脂からなるバックアップ材を設け、ガラス板面と前面板材、および裏面側金具間の周縁部には弾性材からなるリング状のパッキンを設け、該パッキンの外周部にシール材を充填した構造としたことを特徴とするガラス板の支持構造である。
【００１３】
あるいはまた、本発明は、上述の支持金具を用いて、上下左右に並設し立設する複数枚のガラス板の隣接するコーナー突き合わせ目地部を支持する支持構造において、隣接するガラス板の下端コーナー部をガラス受部材のヒンジ部の環状体に固着、かつヒンジ部によってそれぞれ独立して回動自在な一対の支持板で支持し、かつ該支持板は裏面側金具に固着した支持ピンによって支持され、ガラス板のコーナー突き合わせ部の前面より前面側金具に固着したボルト部を目地部に配設した前記ガラス受部材のヒンジ部内に挿通させると共に、裏面側金具の筒状部と螺合させて、ガラス板を締付支持し、裏面側金具は裏面側に設けた構造体に連結固着させ、ガラス板と前面板材、および裏面板材間の周縁部には弾性材からなるリング状のパッキンを設け、該パッキンの外周部にシール材を充填し、かつガラス受部材の支持板とガラス板のコーナー近傍の下端間に硬質樹脂からなるバックアップ材を設けた構造としたことを特徴とするガラス板の支持構造である。
【００１４】
あるいはまた、本発明は、前記並設したガラス板のコーナー目地部内に配設したガラス受部材、および裏面板材に固着の筒状部がガラス板端部に当接しないように、ガラス板のコーナー部に切欠部を設けたことを特徴とする上述のガラス板の支持構造である。
【００１５】
あるいはまた、本発明は、上述の支持構造とするために、上下左右に並設し立設する複数枚のガラス板の隣接するコーナー突き合わせ目地部を支持する施工方法において、構造支柱側に連結し、ガラス板の荷重を支える裏面側金具と、前記前面側金具の切欠部を有した前面板材とを螺合させて仮止めした後、前面板材の切欠部を通してガラス板を１枚づつ施工および、９０度回転させ、４枚のガラス板の取付完了後、前面板材と裏面側金具とを締付固定し、前面板材の外周部に全面カバー材を螺合させることにより、支持金具を取付けた後にガラス板の取付を可能としたことを特徴とするガラス板の施工方法である。
【００１６】
【発明の実施の形態】
本発明は、図８〜図１０に示すように、建物の外壁用として、立設する複数枚のガラス板１、１、・・を上下左右に並設し、該ガラス板１、１、・・の隣接するコーナー突き合わせ目地部５の室内外の両面側より該コーナー部の端部を孔明けせずに締付挟持により支持する支持金具２および支持構造、並びにその施工方法に関するものである。
【００１７】
本発明のガラス板の支持金具として、まず図６に示すようにガラス受部材３０が固定タイプであるが、上下左右に並設し立設する複数枚のガラス板１、１、・・の各下端コーナー突き合わせ部は、ガラス受部材３０で支持され、かつ前後両面より前面側金具１０と裏面側金具２０との螺合によって締付支持する支持金具２であって、前記ガラス受部材３０が裏面側金具２０に直接固着され、前面側金具１０が、１／４円以上１／２円未満の切欠部１１ａを有する前面板材１１と、該前面板材１１の中心に固着し裏面板材２１に設けた雌ネジ部と螺合するボルト部１２と、前面板材１１の外周の円弧状部に設けた螺刻部１１ｂと外接し、螺合する前面カバー材１３からなる支持金具２から構成される。
【００１８】
ガラス受部材３０は、裏面側金具２０に直接固着されたものを示したが、裏面側金具２０に着脱自在に支持されるようにしてもよい。
【００１９】
前記前面板材１１の切欠部１１ａを１／４円以上としたのは、前面板材１１を取付後に、１／４円以上の切欠部を通して方形なガラス板を装着させるためである。
【００２０】
切欠部１１ａを１／２円未満としたのは、図５に示すように、前面板材１１を取付後、３枚のガラス板が落下しないように前面支持材を取り付けた後、前面板材だけで１／４円の切欠部を通して方形なガラス板を装着させるためである。
【００２１】
切欠部１１ａの角度が１／２円以上であると、４枚目のガラス板の取付時に、既に取付完了した３枚のガラス板の支持が不安定となる。
【００２２】
続いて、好ましい支持金具の例を、図１乃至図４に示す。
【００２３】
図１乃至図４に示すように、本発明の支持金具２は、ガラス板１の下端コーナー部を支持する前記ガラス受部材３０が、並設したガラス板１、１間の十字状目地部中心に挿通したヒンジ機構を有し、該ヒンジ機構はヒンジ部３１の環状体の外周面に固着させた一対の支持板３２、３２を有し、ガラス板１、１の突き合わせコーナー部の裏面側に介在させる前記裏面側金具２０が、裏面板材２１とその中心に固着し前記ガラス受部材３０のヒンジ部３１の環状体に内接する筒状部とからなり、前面側金具１０の前記切欠部１１ａを有する前面板材１１と、該前面板材１１が、該前面板材１１の中心に固着し裏面板材２１の雌ネジと螺合するボルト部１２と、前面板材１１の円弧部１１ｂと外接し螺合する前面カバー材１３とからなり、ガラス板１の取付前に前面板材１１を取付可能にしたものである。
【００２４】
前記裏面板材２１に配設した一対の支持ピン２４、２４は、左右の支持板３２、３２の下面の裏面側金具２０側の端部近傍を当接支持し、ガラス板１、１、・・の揺動によっても当接しない長さとすると良い。
本発明の支持構造としては、図６に示すように、上述の支持金具２を用いて、上下左右に並設し立設する複数枚のガラス板１、１、・・の各下端コーナー突き合わせ部をガラス受部材３０で支持し、かつガラス板１のコーナー部の両面より前面側金具１０と裏面側金具２０との螺合によって締付支持するガラス板の支持構造において、前記ガラス受部材３０は裏面側金具に固着されており、ガラス板１のコーナー突き合わせ部の前面より１／４円以上１／２円未満の切欠部を有した前面板材１１に垂設したボルト部１２を、構造柱に連結固着した裏面側金具２０の裏面板材２１と螺合させてガラス板１を締付支持し、前記切欠部１１ａを有した前面板材１１の外周部に前面カバー材１３を螺合させ、ガラス受部材３０のガラス板１の下端との当接部に硬質樹脂からなるバックアップ材３を設け、ガラス板１の各面と前面板材１１、および裏面側金具２０間の周縁部には弾性材からなるリング状のパッキン４、４’を設け、該パッキン４、４’の外周部にはシール材９’、９を充填した構造とした。
【００２５】
また、図１乃至図４に示したガラス板の支持構造は、前記図６に示したガラス受け部材３０を裏面側金具２０に固定したものに較べて、可動できるようにしたので、層間変位に対応し易く好ましい。
【００２６】
図１乃至図４は、隣接するガラス板１の下端コーナー部をガラス受部材３０のヒンジ部３１の環状体に固着、かつヒンジ部３１によってそれぞれ独立して回動自在な一対の支持板３２、３２で支持し、かつ該支持板３２、３２は裏面側金具２０に固着した支持ピン２４、２４によって支持され、ガラス板１のコーナー突き合わせ部の前面より前面側金具１０に固着したボルト部１２を目地部５に配設した前記ガラス受部材３０のヒンジ部３１内に挿通させると共に、裏面側金具２０の筒状部２３と螺合させて、ガラス板１を締付支持する。
【００２７】
裏面側金具２０は裏面側に設けた構造体７に連結固着させ、ガラス板１と前面板材１１、および裏面板材２１間の周縁部には弾性材からなるリング状のパッキン４、４’を設け、該パッキン４、４’の外周部にシール材９、９’を充填し、かつガラス受部材３０の支持板３２、３２とガラス板１のコーナー近傍の下端間に硬質樹脂からなるバックアップ材３、３を設けた支持構造である。
【００２８】
好ましくは、前記並設したガラス板１のコーナー目地部内に配設したガラス受部材３０、および裏面板材２０に固着の筒状部２３がガラス板端部に当接しないように、ガラス板１のコーナー部に切欠部１ａを設けた。
【００２９】
好ましい実施例である図１、図２、および図４に示したガラス板の支持構造を詳述する。
【００３０】
ヒンジ機構を有するガラス受部材３０を、ガラス板１、１、・・間の十字状目地部５の交点部に挿通させた。
【００３１】
ヒンジ部３１の環状体は蝶番構造になって分割されており、該分割された環状体のそれぞれの外周面の側端部より互いに反対方向に向けて板状またはチャンネル状の支持板３２、３２を水平に突出固着させ、支持板３２、３２が前記ヒンジ機構によってそれぞれ独立して回動自在となっている。
【００３２】
支持板３２、３２の回動範囲は、水平方向から上部側に回動可能で、互いに反対方向に略１８０度水平方向に開いた時点で支持板同士が当接して停止するが、ガラス板１の荷重によって、支持板３２、３２の広がりを抑えているのは、支持板３２、３２の下端に当接して支持する後述の支持ピン２４、２４である。
【００３３】
また、支持板３２、３２は、十字状目地部５の上方に隣接位置するガラス板１、１の下端辺のコーナー近傍をバックアップ材３、３を介して当接支持可能な長さとした。
【００３４】
また、図４に示すように、裏面側金具２０は、隣接するガラス板１、１のコーナー突き合わせ部の裏面側（屋内側）に配設し、隣接するガラス板１、１のコーナー部を挟持できる程度の面積を有した板状の裏面板材２１と、裏面板材２１のガラス１面側に垂設し、かつガラス受部材３０のヒンジ部３１の環状体内に遊挿可能な裏面側金具２０の筒状部２３と、図２に示すように、ヒンジ部３１の環状体の左右両側に少なくとも１対以上の上述の支持ピン２４、２４を配設し固着したものである。
【００３５】
これら左右に対に設けた支持ピン２４、２４はガラス受部材３０の支持板３２、３２の下面の裏面側の端部に当接するように配置され、支持ピン２４、２４の長
さは、ガラス板１と裏面板材２１間の間隔よりも短く、すなわちガラス板１が上下に揺動しても支持ピン２４に当接しないような長さとしたものであり、同一径の支持ピンでも良く、頭部と棒状部からなる支持ピンであっても良い。
【００３６】
図１および、図４に示すように、裏面板材２１のガラス板面側の略中心に固着した筒状部２３とは反対側の面には、筒状部２３と同心位置に支持桿２２を突設固着させ、該支持桿２２の先端には雄ネジ部２２ａを設けて、図６〜図８に示す構造柱７に固着した雌ネジ部８ａを有した受具８と螺合して連結し、受具８に設けたビス取付孔８ｂに固定ビス２６を螺合させ、さらに固定ビス２６の先端を支持桿２２のキー溝２２ｂ内に押しつけて固定し、裏面側金具２０が緩んで回転しないようにした。
【００３７】
図４に示すように、裏面側金具２０の筒状部２３の長さは、前記ガラス受部材３０の支持板３２、３２の幅よりもやや長くしてクリアランスを設けている。
【００３８】
さらに、前面側金具１０は、隣接するガラス板１、１、・・のコーナー突き合わせ部の前面側（屋外側）に配設し、隣接するガラス板１、１、・・のコーナー部を挟持できる程度の面積を有した板状の前面板材１１と、前面板材１１のガラス面１側に垂設し、かつ裏面側金具２０の筒状部２３内に嵌挿又は螺合するボルト部１２を配設したものである。
【００３９】
前記前面板材１１は、図２に示すような１／４円以上の切欠部１１ａから、図５に示すような１／２円未満の切欠部１１ａを有し、さらに該前面板材１１の外周の円弧部に設けた雄ネジ部１１ｂと螺合する雌ネジ部１３ｂを有する前面カバー材１３によって、切欠部を見えなくさせると共に、切欠部１１ａによって締付の効かないガラス板１、１、・・を、前面カバー材１３の周辺部によって締付挟持することができる。
【００４０】
裏面板材２１の左右に対に支持ピン２４、２４を設けた実施例においては、ガラス受部材３０の支持板３２、３２の下面側端部に当接するような配置とし、支持ピン２４、２４の長さは、ガラス板１と裏面板材２１間の間隔よりも短く、すなわちガラス板１が地震によって上下に揺動しても支持ピン２４、２４に当接しない長さとなるようにした。
【００４１】
また、ボルト１２の長さは、裏面側金具２０の筒状部２３と螺合させたときに、裏面板材２１の中心部を突き抜けて、支持桿２２に設けた固定ビス用孔の位置よりも長く設けた。
【００４２】
前面板材１１と裏面板材２１は見栄えの観点より通常同一形状とするが、異なった形状としても良い。
【００４３】
前面板材１１に垂設したボルト部１２と裏面板材２１に垂設した筒状部２３を螺合させた後で、裏面板材２１に固着した支持桿２２の付け根付近に設けた図示しない固定ビス用孔に螺合させた固定ビス２５によって前面側金具１０のボルト部１２と裏面側金具２０とを固定できる。
【００４４】
前面板材１１の外周部の雄ネジ部１１ｂに前面カバー材１３の雌ネジ部１３ｂを螺合させたときに、前面カバー材１３の外周部に設けた固定ビス用穿孔部１３ａに固定ビス１４を螺合させ締め付ければ、前面カバー１３と前面板材１１とが緩むことはない。
【００４５】
前記ガラス板１、１のコーナー下端部とガラス受部材３０のヒンジ部３１の環状体に固着した支持板３２、３２との間には、硬質樹脂からなるバックアップ材３、３を配設して接着剤等で接着し、ガラス板１、１と支持板３２、３２とが直接当接しないようにし、層間変位によるガラス板１、１、・・の挙動にガラス受部材３０の支持板３２、３２がそれぞれ独立して追従できるようにした。
【００４６】
さらに、前面板材１１と、パッキン４の外周面と、ガラス板１間で囲まれた部分、および裏面板材２１と、パッキン４’の外周面と、ガラス板１で囲まれた部分には弾性材からなるシール材９、９’を全周囲にわたって充填した。
【００４７】
また、ガラス板１、１、・・の隅部には、ガラス板１、１、・・同志が衝突しないように斜め４５度に切欠部１ａ、１ａ、・・を設けた。さらに、切欠部１ａ、１ａ、・・の大きさは、前記並設したガラス板１、１、・・のコーナー目地部中心に配設したガラス受部材３０がガラス板１、１、・・の端部に当接しない程度のものであれば良い。
【００４８】
さらに、ガラス受部材を支持する支持ピンを裏面板材２１に設ける場合には、裏面板材２１の中心より左右対称に少なくとも一対垂設した支持ピン２４、２４とし、上下に隣接するガラス板１、１間の水平な目地部５内とするが、ガラス受部材３０の支持板３２、３２の下面側の長辺側端部のみに当接した状態で、ガラス板１、１を支持板３２、３２で支持する。
【００４９】
また、前面板材１１に設けた支持ピンと裏面板材２１に設けた支持ピン２４、２４のそれぞれの長さはガラス板の揺動に対しても接触しない長さ、すなわち前面板材１１とガラス板１、１、・・間の隙間、裏面板材２１とガラス板１、１、・・間の隙間よりも小寸法でありガラス受部材３０の支持板３２、３２を支持可能な長さである。
【００５０】
よって、裏面板材２１に設けた支持ピン２４によって、支持板３２、３２を当接支持している状態において、支持板３２、３２はガラス板１、１に当接しない位置に設ける必要があるが、裏面板材２１に設けた支持ピン２４、２４のいずれもガラス板１に当接することはない。
【００５１】
ガラス受部材３０の支持板３２、３２の形状は、平板状でも良いが、ガラス板１、１の荷重に充分耐えられるように断面がコ字状の下向きのチャンネル状とするのが好ましい。この場合の支持ピン２４としては頭部と棒状部からなるものとすると良く、支持ピン２４の棒状部をチャンネル状の支持板３２の端部に当接させて、支持ピン２４の径の大きな頭部をコ字状の開口部内に収めるようにした。
【００５２】
続いて、本発明のガラス板の施工方法について説明する。
【００５３】
図１、図６に示すように、本発明のガラス板の施工方法は、上下左右に並設し立設する複数枚のガラス板１、１、・・の隣接するコーナー部を突き合わせた十字状目地部を両面より前面側部材１０と裏面側部材２０とで挟持して支持する施工方法であるが、ガラス板１、１、・・の両面より挟持して設ける前面側金具１０と裏面側金具２０を螺合により仮に取り付けた後に、ガラス板１を１枚づつ取り付けていく方法である。
【００５４】
ガラス板１の前面側金具１０は、切欠部１１ａの大きさが１／４円以上１／２円未満とした前面板材１１と、前面板材１１と螺合によって結合可能な前面カバー材１３とからなり、裏面側金具２０は従来より用いられた金具をはじめとして前面板材１１のボルト部１２と螺合し、ガラス板１を締付できる形状であれば、どんな形状であってもよい。
【００５５】
ガラス板１を取り付けする前に、切欠部１１ａを有した前面板材１１で仮締めしておき、裏面側金具２０と螺合させて仮固定させる。
【００５６】
その後で、ガラス板１を前面板材１１の切欠部１１ａの空間を利用して取り付けし、取り付け完了後は、取り付けたガラス板１が落下しないように前面板材１１を回転させるが、次のガラス板１のコーナー部が切欠部１１ａの位置に来るように前面板材１１を９０度回転させるのが望ましい。
【００５７】
ガラス板１を１枚目より順次取り付けると共に９０度回転させ、４枚のガラス板をすべて取り付けた段階で、前面板材１１を所定の締付力となるように締め付け回転させた後、前面板材１１の外周に設けた雄ネジ部に前面カバー材１３の雌ネジ部１３ｂを螺合させて、ガラス板１のコーナー部を挟持できるようにした。
【００５８】
前記前面側金具１０の切欠部１１ａを有した前面板材１１とを螺合させて仮止めした後、前面板材１１の切欠部１１ａを通してガラス板１を１枚づつ施工および、９０度回転させ、４枚のガラス板１、１、・・をすべて取付完了後、前面板材１１と裏面側金具２０とを締付固定し、前面板材１１の外周部に全面カバー材１３を螺合さ、支持金具２を取付けた後にガラス板１の取付を可能としたものである。
【００５９】
前面側金具１０として、切欠部１１ａを設けた前面板材１１と前面板材１１と螺合する前面カバー材１３からなる支持金具２によって支持金具２をガラス板の取付前に取り付け、後からガラス板を１枚づつ施工できる施工方法としては、図示した支持金具２に限らず、すべての支持金具２に応用できる。
【００６０】
続いて本発明の作用を説明する。
【００６１】
図６をはじめとして、図１、図２、図４に示したように、本発明の支持金具２は、上下左右に並設し立設する複数枚のガラス板１、１、・・の隣接するコーナー突き合わせ目地部５内にガラス受部材３０を設け、該ガラス受部材３０上にガラス板１、１、・・の下端隅部をバックアップ材３、３を介して載置させて支持させ、前面側金具１０のガラス板１の前面側を押さえつける前面板材１１に１／４円以上１／２円未満の大きさの切欠部１１ａを設けたので、ガラス板１のはめ込み前前に前面板材１１と裏面側金具２０とを螺合させて仮締めさせておき、前面板材１１の切欠部１１ａを通してガラス板１を一枚づつ取付および切欠部１１ａを９０度回転させて、取り付けたガラス板１が落下しないようにガラス板１を順次セットし、４枚のガラス板１、１、・・を取付後に、前面板材１１を覆うように前面板材１１に螺着させた前面カバー材１３で４枚のガラス板１、１、・・を押さえつけ、裏面側金具２０との螺合によって締付るようにした。
【００６２】
前記前面板材に被さるように前面カバー材を設けたことによって、切欠部が表に出ることもなく、また、切欠部によって支持できないガラス板についても、前面カバー材によって支持することができる。
【００６３】
このように、切欠部１１ａを設けた前面板材１１をガラス板１よりも先に取り付け、該前面板材１１をガラス板１の取付の都度９０度回転させるようにしたので、従来のように４枚のガラス板１、１、・・が取り付け完了まで人手等の別の手段で支えておく必要がなく、作業者にとって安全性が向上した。
【００６４】
また、ガラス板１のコーナー部を両面より挟むようにしたので、ガラス板１、１、・・のコーナー隅部に孔を明けずにガラス板１、１、・・を支持することができる。
【００６５】
さらに、ガラス受部材３０の支持板３２、３２は、構造柱７に固着支持された裏面側金具２０に固着した支持ピン２４、２４上に載置されているだけであり、ヒンジ部３１を中心にして略水平方向より上方に回動可能であるが、通常状態ではガラス板１、１、・・の自重によって固定されている。
【００６６】
また、前面側金具１０の前面板材１１の中心に固着したボルト部１２を、ガラス受部材３０のヒンジ部３１の環状体内に挿通させると共に、構造柱７に支持桿２２を介して連結固着した裏面側金具２０の筒状部２３と螺合させて、ガラス板１、１、・・の目地部５を中心としたガラス板１のコーナー部を締付支持するので、ガラス板１に孔を明けなくてもガラス板１の支持を確実とし、ガラス板１の自重や面外方向の荷重等に対しても強度を低下させることがなく、また、大面積のガラススクリーンを形成することができる。
【００６７】
図１乃至図４に示すような好ましい支持金具、支持構造の場合には、図３に示したように、ガラス受部材３０のヒンジ部３１は、その両端に一対の支持板３２、３２を固着させているので、一対の支持板３２、３２はヒンジ部を中心軸として略水平方向から上方に回動自在である。
【００６８】
図３の点線は層間変位が発生していない状態の通常状態のガラス板１を示し、二点鎖線は層間変位が発生しロッキングが起こった時のガラス板１と支持金具２の状態を示している。
【００６９】
ガラス板１の下端コーナー部は、それぞれバックアップ材３、３を介して各支持板３２、３２上に載置されているので、ガラス板１は金属製の支持板３２によって破損することはない。
【００７０】
また、支持板３２の形状を、単なる板状でなく、断面が略コ字状のチャンネル状とすれば、ガラス板１の荷重に充分耐えることができる。さらに、層間変位の発生していない通常時、支持板３２、３２は略水平状態となるが、断面コ字状のチャンネル状の支持板３２、３２の下端を支持ピン２４、２４で当接させて支持しているので、これ以上支持板３２、３２が広がることはない。
【００７１】
さらに、裏面側金具２０の裏面板材２１に垂設した支持ピン２４、２４によって、ガラス受部材３０の支持板３２、３２の下面側端部近傍を支持しており、層間変位によるガラス板１にロッキングが起こり、ガラス板１のコーナー片端部を支点として他端側が上方に持ち上がると、支持板３２より下方のガラス板１が支持板３２を上方に押し上げることになり、支持板３２が固着しているヒンジ部３１の環状体は構造体７側と固着しているので、ヒンジ部３１を支点にして支持板３２は上方に回動し、支持板３２が支持ピン２４から離れて浮き上がることになる。
【００７２】
この時、もう一方の支持板３２の下方にあるガラス板１のコーナーはロッキングの支点となっており上方に持ち上がることはないので、支持板３２は押し上げられることはなく水平を保っている。
【００７３】
このようにして、層間変位によるガラス板１の変位挙動に追従して支持板３２が可動自在であるので、ガラス板１に無理な力がかかることはない。
【００７４】
また、層間変位が収まり元の状態に戻った時には、各支持板３２、３２は上部側からのガラス板１の自重で図２の略水平状態に復帰することになる。
【００７５】
また、支持金具２で支持されるガラス板１の厚みに較べて、前面板材１１と裏面板材２１間の間隔を広くしたのは、ガラス板１と前面板材１１、ガラス板１と裏面板材２１間に緩衝材としての弾性材からなるリング状のパッキン４、４’を設けるようにしたためである。
【００７６】
前面板材１１の周辺部とガラス板１間、および裏面板材２１の周辺部とガラス板１間にはゴム等の弾性材からなるパッキン４を形成し、さらにその外周にはシール材９を充填して雨水の浸入を防ぐと共に、面外方向からの風圧荷重によってガラス板１が変形しても、パッキン４が緩衝材として働き、ガラス板の変形を吸収するので、ガラス板１に無理な力がかかることはない。また、前面板材１１、裏面板材２１とガラス板１との当接による破損も防止できるようにした。
【００７７】
このように、縦横に並設した複数枚のガラス板１、１、・・のそれぞれの十字状目地部５に支持金具２を設け、支持金具２によって支持金具２より上部側のガラス板１、１の垂直荷重を支持し、さらに支持金具２によって上下の４枚のガラス板１、１、・・の水平荷重を支持するものである。
【００７８】
このようにして、図８、図９、図１０に示すように、支持金具２の支持桿２２を構造柱７に固着した雌ネジ部を有した受具８に螺合させて連結し、ガラススクリーンを形成した。
【００７９】
ガラス板１と支持金具２の前面板材１１間、及びガラス板１と支持金具２の裏面板材２１間に設けたパッキン４は、緩衝材としての機能も備えている。
【００８０】
パッキン４、４’は、リング状で、その外径は、前面板材１１の外径とほぼ同一サイズの成形した弾性ゴム等からなり、前面板材１１、裏面板材２１に予め接着剤等で接着させておくと好都合であり、前面側金具と裏面側金具の嵌合または螺合によりガラス板に密着させる。
【００８１】
支持金具２をガラス板１、１、・・の突き合わせ目地部５に装着後、ガラス板１、１、・・間にシリコンシーラント等のシーリング材を充填するとともに、支持金具２の前面カバー材１３、裏面板材２１とガラス板１、１板間でかつパッキン４、４’の外側の凹部にシリコーンシーラント等のシーリング材を充填させれば、ガラス板１、１、・・や支持金具２にシール材９が密着するので、支持金具２から雨水等の室内への浸入を阻止できる。
【００８２】
また、支持金具２の各部材はＳＵＳ等の錆びない金属が望ましいが、防錆塗装処理やメッキ等の処理をしたＳＳ材でも良い。
【００８３】
尚、ガラス板１とは強化ガラス、半強化ガラス、未強化ガラスのいずれか、あるいはこれらを組み合わせてＰＶＢやＥＶＡ等の中間膜または樹脂注入で接着した合わせガラス、あるいはまた、前記のガラスに飛散防止樹脂膜を貼着したもの等が対象となる。
【００８４】
以上好適な実施の形態について述べたが、本発明はこれに限定されるものではなく種々の応用が考えられるものである。
【００８５】
本発明のガラス板１の支持構造からなるガラススクリーンの実施例を図８〜図１０に示すが、これに限定されるものではない。
【００８６】
ガラス板１、１、・・同士を突き合わせた目地部５の間隔は例えば１２〜１５ｍｍで、支持金具２の前面板材１１は例えば直径７０〜１１０ｍｍの切欠部を有した円形状、裏面板材２１は例えば直径８０〜１３０ｍｍの円形状、または縦横の外形寸法が例えば縦８０から１２０ｍｍ前後、横８０〜１８０ｍｍ前後の円形状、方形状、楕円形状、または矩形状としてもよい。
【００８７】
このように、本発明によれば、縦横に並設された複数枚のガラス板１の突き合わせコーナー目地部５に設ける支持金具２によって、その上部側に位置する２枚のガラス板の自重を支持し、支持金具２に係わる上下左右の４枚のガラス板１、１、・・に加わる風圧荷重等の水平荷重を支持する。
【００８８】
【発明の効果】
本発明によれば、大面積のガラススクリーンを形成する場合に、前面側金具の前面板材に１／４円以上１／２円未満の大きさの切欠部を設けたことにより、ガラス板を嵌め込む前に前面板材を取付、その後で切欠部よりガラス板を嵌め込むことができ、しかも前面板材を回転させることにより取り付けたガラス板が落下することがないので、支持が不要である。
【００８９】
また、前面板材に被さるように前面カバー材を設けたことによって、切欠部が表に出ることもなく、また、切欠部によって支持できないガラス板についても、前面カバー材によって支持することができる。
【００９０】
本発明の支持金具によって、ガラス板に孔を明けずにガラス板の支持を確実とし、ガラス板の自重や面外方向の荷重等に対しても強度を低下させることがない。
【００９１】
また、地震等による層間変位の発生により、上下左右に並設されたガラス板がロッキングにより傾き、ガラス板の片端が持ち上がっても、ガラス板の持ち上がった上部片端コーナーだけが支持金具の支持板を追従して持ち上げ、他端側コーナーは支持板を持ち上げることなく、ヒンジ機構により個々のガラス板の挙動に追従して支持板が別々に動くので、ガラス板に無理な力がかかることが無く、ガラス板の破損が起こりにくい。

This is a construction method in which the joint part is sandwiched and supported by the front side member 10 and the back side member 20 from both sides, but the front side bracket 10 and the back side bracket provided by sandwiching from both sides of the glass plates 1, 1,. This is a method of attaching the glass plates 1 one by one after temporarily attaching 20 by screwing.
[0054]
The front side metal fitting 10 of the glass plate 1 includes a front plate material 11 in which the size of the notch 11a is not less than 1/4 and less than 1/2 yen, and a front cover material 13 that can be coupled to the front plate 11 by screwing. Thus, the back side metal fitting 20 may have any shape as long as it can be screwed into the bolt portion 12 of the front plate 11 including the metal fittings conventionally used and can fasten the glass plate 1.
[0055]
Before the glass plate 1 is attached, the glass plate 1 is temporarily tightened with the front plate member 11 having the notch portion 11a, and is screwed with the rear metal fitting 20 to be temporarily fixed.
[0056]
After that, the glass plate 1 is attached using the space of the notch 11a of the front plate member 11, and after the attachment is completed, the front plate member 11 is rotated so that the attached glass plate 1 does not fall. It is desirable to rotate the front plate 11 by 90 degrees so that the corner portion of 1 is positioned at the notch 11a.
[0057]
The glass plate 1 is attached sequentially from the first sheet and rotated by 90 degrees, and at the stage where all four glass sheets are attached, the front plate member 11 is tightened and rotated so as to have a predetermined tightening force, and then the front plate member 11 is rotated.

The construction method that can be constructed one by one is not limited to the illustrated support fitting 2 and can be applied to all support fittings 2.
[0060]
Next, the operation of the present invention will be described.
[0061]
As shown in FIG. 1, FIG. 2, FIG. 4, the support fitting 2 of the present invention is adjacent to a plurality of glass plates 1, 1,. The glass receiving member 30 is provided in the corner butt joint part 5 to be mounted, and the lower end corners of the glass plates 1, 1,... Are placed on and supported by the glass receiving member 30 via the backup materials 3, 3, Since the front plate 11 that holds the front side of the glass plate 1 of the front side metal fitting 10 is provided with a notch 11a having a size of 1/4 or more and less than 1/2 Yen, the front plate 11 before the glass plate 1 is fitted. And the rear side metal fitting 20 are screwed together and temporarily tightened, the glass plate 1 is attached one by one through the notch portion 11a of the front plate member 11, and the notch portion 11a is rotated by 90 degrees. Set the glass plate 1 in order so that it does not fall. After attaching the lath plates 1,..., The four glass plates 1, 1,... Are pressed by the front cover member 13 screwed onto the front plate member 11 so as to cover the front plate member 11. Tightened by screwing.
[0062]
By providing the front cover material so as to cover the front plate material, the notch portion does not appear on the surface, and a glass plate that cannot be supported by the notch portion can be supported by the front cover material.
[0063]
In this way, the front plate 11 provided with the notch 11a is attached before the glass plate 1, and the front plate 11 is rotated 90 degrees each time the glass plate 1 is attached. It is not necessary for the glass plates 1, 1,... To be supported by another means such as manpower until the attachment is completed, and safety for the worker is improved.
[0064]
Further, since the corners of the glass plate 1 are sandwiched from both sides, the glass plates 1, 1,... Can be supported without making holes in the corners of the glass plates 1, 1,.
[0065]
Further, the support plates 32, 32 of the glass receiving member 30 are only placed on the support pins 24, 24 fixed to the back-side metal fitting 20 fixedly supported to the structural column 7, and the hinge portion 31 is centered. In the normal state, the glass plate 1, 1,... Is fixed by its own weight.
[0066]
In addition, the bolt portion 12 fixed to the center of the front plate member 11 of the front side metal fitting 10 is inserted into the annular body of the hinge portion 31 of the glass receiving member 30 and connected to the structural column 7 via the support rod 22. Since the corner portion of the glass plate 1 centered on the joint portion 5 of the glass plate 1, 1,... Is tightened and supported by screwing with the cylindrical portion 23 of the side metal fitting 20, a hole is formed in the glass plate 1. Even if not, the support of the glass plate 1 is ensured, the strength is not lowered even with respect to the weight of the glass plate 1 or the load in the out-of-plane direction, and a large-area glass screen can be formed.
[0067]
In the case of a preferable support fitting and support structure as shown in FIGS. 1 to 4, as shown in FIG. 3, the hinge portion 31 of the glass receiving member 30 has a pair of support plates 32 and 32 fixed to both ends thereof. Therefore, the pair of support plates 32 and 32 can be rotated upward from a substantially horizontal direction with the hinge portion as a central axis.
[0068]
The dotted line in FIG. 3 shows the glass plate 1 in a normal state in which no interlayer displacement has occurred, and the two-dot chain line shows the state of the glass plate 1 and the support bracket 2 when the interlayer displacement has occurred and rocking has occurred. Yes.
[0069]
Since the lower end corner of the glass plate 1 is placed on the support plates 32 and 32 via the backup members 3 and 3, the glass plate 1 is not damaged by the metal support plate 32.
[0070]
Further, if the shape of the support plate 32 is not a mere plate shape but a channel shape having a substantially U-shaped cross section, the load of the glass plate 1 can be sufficiently resisted. Further, the support plates 32 and 32 are in a substantially horizontal state during normal times when no interlayer displacement occurs, but the lower ends of the channel-shaped support plates 32 and 32 having a U-shaped cross section are brought into contact with the support pins 24 and 24. Therefore, the support plates 32 and 32 do not spread any further.
[0071]
Furthermore, the support pins 24, 24 suspended from the back plate 21 of the back metal fitting 20 support the lower surface side end portions of the support plates 32, 32 of the glass receiving member 30, and the glass plate 1 due to interlayer displacement When locking occurs and the other end of the glass plate 1 is lifted upward with the corner one end of the glass plate 1 as a fulcrum, the glass plate 1 below the support plate 32 pushes the support plate 32 upward, and the support plate 32 is fixed. Since the annular body of the hinge portion 31 is fixed to the structure 7 side, the support plate 32 rotates upward with the hinge portion 31 as a fulcrum, and the support plate 32 floats away from the support pin 24. .
[0072]
At this time, the corner of the glass plate 1 below the other support plate 32 is a fulcrum for locking and does not lift upward, so that the support plate 32 is not pushed up and remains horizontal.
[0073]
In this way, since the support plate 32 is movable following the displacement behavior of the glass plate 1 due to the interlayer displacement, no excessive force is applied to the glass plate 1.
[0074]
Further, when the interlayer displacement is settled and the original state is restored, the support plates 32 and 32 are returned to the substantially horizontal state of FIG. 2 by the weight of the glass plate 1 from the upper side.
[0075]
In addition, the distance between the front plate member 11 and the rear plate member 21 is increased between the glass plate 1 and the front plate member 11 and between the glass plate 1 and the rear plate member 21 as compared with the thickness of the glass plate 1 supported by the support fitting 2. This is because the ring-shaped packings 4, 4 ′ made of an elastic material as a cushioning material are provided.
[0076]
