Description

【０００１】
【発明の属する技術分野】
本発明は、例えばガラス張りカーテンウォールを構成する際に用いられるガラスや板材などを支持するための方立機構に関するものである。
【０００２】
【従来の技術】
近年、建築物の開放感や採光性の向上、あるいは外観デザイン等により、ビルや公共施設のホールなどの壁面をガラスだけで構成するガラス張りカーテンウォールが普及してる。このようなガラス張りカーテンウォールは、建築物の開口部を複数枚のガラス板材で覆うものであるが、各ガラス板材は専用の支持部材を用いた方立機構で支持される。
【０００３】
従来から用いられている方立機構としては、開口部の天井部と床部とにそれぞれ上枠、下枠を取り付け、この上下枠間に亘って配設される柱状の方立本体を、ガラス板材の幅相当の間隔毎に横方向へ複数本設置し、各方立本体の上下方向に、ガラス板材の高さ相当の間隔毎に複数個の支持部材を取り付け、各支持部材で隣り合うガラス板材の下端隅部を左右各々に支持するものが一般的である。
【０００４】
この方立機構では、一枚のガラス板材につき、下端両側が左右の方立本体に配された支持部材上に載置されて支持される構成となっており、また通常は、ガラス板材の上端両側は、上段のガラス板材の下端両側を支持するために左右上方に位置する支持部材の下部で係止されている。
【０００５】
このようなカーテンウォールでは、各ガラス板材が外気に晒されており、強風による風圧や、また地震による振動などの外力作用を直接受けてしまい、ガラス板材に上下動や回転等の変動、所謂層間変位を生じせしめる。したがって、方立機構は、このような層間変位を生じてもガラス板材を安定に支持できるものでなければならない。
【０００６】
そこで、支持部材のガラス載置部がガラスの層間変位に伴って移動できる構成のものが考えられている。例えば、特許第２９２２５１０号には、層間変位が生じた時、ガラス載置部が所定支持位置から上側の範囲で上下方向へ移動可能としたものが開示されている。
【０００７】
【発明が解決しようとする課題】
しかしながら、ガラス板材の層間変位は、垂直方向への上下動だけでなく、回転移動することもある。この場合、上記の如き従来の方立機構では、水平方向に沿ったガラス載置部に対してガラス板材の隅部の下端辺は傾き、載置部との当接支持領域が小さくなってガラスに局所的な応力が作用する。この局部的負荷がガラス破損の原因となり得る。
【０００８】
従って、ガラス張りカーテンウォールの安定性、安全性を長期にわたって維持するには、より層間変位に十分に適応して常に安定してガラス板材を支持できる方立機構が望まれる。
【０００９】
本発明の目的は、上記問題点に鑑み、ガラス板材の様々な層間変位に対応して、ガラス板材に局所的負荷を生じせしめることなく常に安定で安全にガラス板材を支持できるガラス板材支持用部材を提供することにある。特に、回転方向（又は横方向やねじれ方向等の複雑な）の変位にも対応できる方立て機構の支持部材を提供することも本発明の重要な目的である。例えば、ガラス板材に様々な層間変位が生じてもガラス板材に対する支持面の当接領域が基準状態からほとんど減少することなく安定に支持できるガラス板材支持用部材を提供することも本発明の目的である。
【００１０】
【課題を解決するための手段】
上記目的を達成するため、請求項１に記載の発明では、複数枚のガラス板材を建築物の開口部に取り付けて壁面を形成するために、前記建築物の構造体に前記開口部の上下方向に配設される柱状の方立本体の所定の高さ位置に固定され、前記方立本体を挟んで隣り合って配置される二つのガラス板材を支持するガラス板材支持用部材において、前記支持用部材は、前記方立本体に固定される固定部を有する基台部と、前記二つのガラス板材の一方の左下隅部が載置される第１の支持部と、他方のガラス板材の右下隅部が載置される第２の支持部と、これら二つの支持部を連結するロッキング部材と、を備え、前記ロッキング部材は、前記支持用部材の中心線を挟んで左右対称位置において、前記二つの支持部をそれぞれ前記開口面方向に沿って回動可能な状態に軸支すると共に、前記二つのガラス板材を支持する際の基準位置にある状態で、前記二つの軸支部がそれぞれ前記基台部に下方から支承されて保持されており、前記二つの支持部の軸支部のうちの一方の軸支部を回転中心として、他方の軸支部側を回動可能な状態で前記基台部に設置されていることを特徴とするものである。
【００１１】
また、請求項２に記載の発明に係るガラス板材支持用部材は、請求項１に記載のガラス板材支持用部材において、前記基台部が、所定の前記二つの支持部が、前記二つのガラス板材を支持する際の基準位置にある状態で、前記二つの支持部を下方から支承する載置台を更に備えていることを特徴とするものである。
【００１２】
本発明の支持用部材は、柱状の方立本体に固定されて使用されるものであり、方立本体部を中心に左右に配されるガラス板材の各下端隅部を支持するものであって、方立本体に固定される固定部を備えた基台部に、第１の支持部と第２の支持部とをロッキング部材を介してそれぞれ回動可能に設けたものであり、第１の支持部（例えば右側の支持部）で右側に配されるガラス板材の左下隅部を支持し、第２の支持部（例えば左側の支持部）で左側のガラス板材の右下隅部を支持するものである。この支持部は、ガラス板材を安定支持するために、ガラス板材の下隅部を前後から狭持するものであることが好ましい。
【００１３】
本発明においては、これら第１と第２の支持部とが、それぞれ前記建築物の開口面上で回動可能にロッキング部材に軸支され、それぞれの配設位置は互いに中心部から対称な位置に配置されている。これは、左右の支持部で均等に支持力が働くようにするためである。
【００１４】
そして、支持部自体は、回動可能に軸支されており、横方向への揺動移動が可能である。また各々の支持部を軸支しているロッキング部材自体が、各支持部の二つの軸支部のそれぞれを支点にして回動可能に構成されており、一方の軸支部を回動中心にして、他方の軸支部側が（ロッキング部材自体を腕として）回動可能である。
【００１５】
従って、例えばロッキング部材の右側の支持部を軸支する軸支部を支点に回動する場合には、ロッキング部材の左側の支持部側が、ロッキング部材自体を腕のようにして時計回り方向に回動し、それに連動して左側の支持部も時計回り方向に回動することとなる。逆に、ロッキング部材の左側の軸支部を支点にする場合には、右側の軸支部側がロッキング部材を腕のようにして反時計回り方向に回動し、それに連動して右側の支持部も反時計回り方向に回動する。
【００１６】
即ち、軸支部自体がロッキング部材に（同時に支持部にも）対して回動可能に軸支されており、さらにロッキング部材を時計方向（又は反時計方向）に、いわばロッキング部材を腕とするクランク機構のようにして回動できるので、横方向の動きや上下方向の動きのみならず、これらの複合的な移動を許容することができるものである。
【００１７】
このような本発明のガラス板材支持用部材によれば、例えばガラス板材に単なる上下方向の変位だけでなく前記開口面方向に沿った時計回りあるいは反時計回りの回転方向の変位が生じた場合においても、第１と第２支持部は、支持部自体の軸支部を中心とした回動とクランク機構のようなロッキング部材の回動によって、二つのガラス板材の回転変位に伴ってそれぞれ生じた右側ガラス板材の左下隅部の移動および左側ガラス下材の右下隅部の移動を許容して、各支持すべきガラス板材の下隅部と一体的に回転移動することができる。従って、第１と第２の支持部のガラス支持面は、ガラス板材の回転に伴って傾いた下隅部の下端辺に対する当接領域をほとんど小さくすることなく良好な当接支持状態を維持できるため、ガラス板材への局部的負荷を生じせしめることなく常に安定的で安全にガラス板材を支持することができる。
【００１８】
このように、第１と第２の支持部のガラス板材に応じた変位は軸回転機構によるものであるため、変位動作は摩擦が少なく滑らかであり、変位運動による支軸部への負担は小さい。またこれら二つの支持部は、それ自身の軸回転とクランク機構のようなロッキング部材の回動作によって地震の際にも左右にスイングして振動や衝撃を吸収でき、ガラス板材と一体的に揺動できるので、ガラス部材が地震の振動で支持面上で飛びはねて衝突したりすることによる破損発生の危険は回避される。
【００１９】
なお、例えばガラス部材に水平横方向へ変位させようとする外力が作用した場合には、ガラス板材が支持面上をスライド移動して支持領域が小さくなってしまわないように、支持部をガラス板材の横水平移動を下部両側から規制できる構成とすればよい。
【００２０】
例えば、ガラス下端辺が載置される支持面に対して直行する縦面をガラス側面のストッパとしてさらに設ければ、支持部は支持面とこの縦面とでガラス下隅部にＬ字状に当接支持することができ、左右両側の支持部でガラス板材の水平横方向の移動が規制できる。
【００２１】
また、請求項２に記載したように、前記二つの支持部が二つのガラス板材を支持する基準位置にある際に、これら二つの支持部を下方から支承する載置台を基台部に設けておけば、層間変位の生じていない平常時には、第１と第２の支持部をロッキング部材に軸支させる軸部に荷重が集中することなく、ガラス板材の自重をこの載置台によってより安定に支持できる。
【００２２】
なお、本発明によるガラス板材支持用部材は、ガラス張りカーテンウォール用の方立機構に限らず、板材や各種パネル等の支持部材に利用できることは言うまでもない。
【００２３】
【発明の実施の形態】
本発明の一実施形態として、ガラス張りカーテンウォールを構成するための方立機構に用いられるガラス板材支持用部材を図１〜図４に示す。本実施形態によるガラス板材支持用部材は、該部材が設置される方立本体およびその機構の基本的な構成は従来と同様のものとし、開口部の天井部と床部とにそれぞれ上枠、下枠を取り付け、この上下枠間に亘る柱状の方立本体を、ガラス板材の幅相当の間隔毎に複数本設置し、各方立本体の上下方向に、ガラス板材の高さ相当の間隔毎に複数個の本ガラス板材支持用部材を取り付け、各ガラス板材支持用部材で隣り合うガラス板材の下端隅部を左右に支持するものである。
【００２４】
ここでは説明の簡便のため、二つのガラス板材を左右に支持するガラス板材支持用部材一つにつきその機構を示すものとする。図１（ａ）はガラス板材支持用部材の部品構成を示す説明図、（ｂ）は部品組み立て時のガラス板材支持用部材の概略斜視図、（ｃ）は方立本体に固定された本ガラス板材支持用部材を屋外側から見た概略正面図、（ｄ）は本ガラス板材支持用部材の概略側面図である。
【００２５】
本ガラス板材支持用部材２は、方立本体１の所定高さ位置にボルト止めなどで固定される固定部（２０，２１）を有する基台部３と、二つのガラス板材の一方の左下隅部が載置される第１の支持部４ａと他方のガラス板材の右下隅部が載置される第２の支持部４ｂと、これら第１と第２の支持部（４ａ，４ｂ）を連結するロッキング部材１０とから主に構成される。
【００２６】
ロッキング部材１０は、第１と第２の支持部（４ａ，４ｂ）を互いに支持用部材２の中心部から対称な位置でそれぞれ前記開口面方向に沿って回動可能に軸支した状態で、基台部３に設置されているものであり、第１と第２の支持部（４ａ，４ｂ）同士を互いに均等な支持力が働くように連結すると共に、これら支持部を基台部３に連結するものである。
【００２７】
具体的には、基台部３の屋外側に設けられた溝部９にロッキング部材１０の下方部分が嵌合して設置されており、上方領域に支持用部材２の中心線を挟んで左右対称位置において第１の支持部４ａの支軸５ａ及び第２の支持部４ｂの支軸５ｂを軸回転可能に支える軸受（１１ａ，１１ｂ）を設けた軸支部（１２ａ，１２ｂ）が形成されている。
【００２８】
これら軸支部（１２ａ，１２ｂ）は、基台部３の前記溝部９の屋外側上端縁に形成された略半円形凹状の支承部（８ａ，８ｂ）に嵌って支承される略円柱形状を有しており、図２に示すように、支承部（８ａ，８ｂ）の面上を転がり滑って一方の軸支部（１２ａ又は１２ｂ）を回転中心として他方の軸支部（１２ｂ又は１２ａ）側が支承部（８ａ，８ｂ）から上方向へ回動可能となっている。
【００２９】
また、第１の支持部４ａは二つのガラス板材の一方のガラス板材Ｇａの左下隅部を、第２の支持部４ｂは他方のガラス板材Ｇｂの右下隅部を支持するものであり、ガラス板材載置部（６ａ，６ｂ）は、それぞれ支持すべきガラス板材の隅部下端辺が載置される支持面（６ｘａ，６ｘｂ）を有し、その前後からガラス板材を狭持できるように側断面形状が上向きコノ字状となっている。なお、本実施形態では、第１および第２の支持部（４ａ，４ｂ）は、それぞれ軸支部（１２ａ，１２ｂ）から支持面（６ｘａ，６ｘｂ）迄に図示のように所定の間隔を有している。即ち、支持面（６ｘａ，６ｘｂ）部分は、軸支部（１２ａ，１２ｂ）から回動可能に垂下された状態となっている。
【００３０】
また、各載置部（６ａ，６ｂ）の基台部３中心寄りには、支持面（６ｘａ，６ｘｂ）と直交する縦面（６ｙａ，６ｙｂ）が更に設けられており、ガラス板材の水平横方向の移動を規制するストッパとして機能する。
【００３１】
またこれら第１および第２の支持部（４ａ，４ｂ）は、載置部（６ａ，６ｂ）の下部に側断面下向きコノ字形状の係止部（７ａ，７ｂ）が設けられており、下段側の左右二つのガラス板材Ｇの左上端隅部および右上端隅部がそれぞれ嵌め入れられてこれらを前後から挟持し係止するものである。
【００３２】
以上のような第１および第２の支持部（４ａ，４ｂ）は、各支軸（５ａ，５ｂ）によってそれぞれロッキング部材１０の対応する軸支部（１２ａ，１２ｂ）の軸受（１１ａ，１１ｂ）に軸回動可能に軸支されている。即ち、第１及び第２の支持部（４ａ，４ｂ）自体が回動可能であり、また軸支部（１２ａ，１２ｂ）自体もロッキング部材１０および支持部に対して回動可能であると共にロッキング部材１０がそれ自身を腕とするクランク機構のように一方の軸支部（１２ａ又は１２ｂ）を回転中心として他方の軸支部（１２ｂ又は１２ａ）側を時計回りまたは反時計回りに回動できるため、第１および第２の支持部（４ａ，４ｂ）は、それぞれ横方向の揺動や上下方向の動きのみならず、これらの複合的な移動を許容することができるものである。
【００３３】
なお平常時は、図１（ｃ）の正面図に示すように、右側ガラス板材の左下隅部と左側ガラス板材Ｇｂの右下隅部は、互いに基台部３の中心部から対称な位置の第１と第２の支持部（４ａ，４ｂ）の載置部（６ａ，６ｂ）に左右均等な支持力で同じ高さ位置、即ち基準位置にて安定に支持される。このとき、同じ段の全てのガラス板材支持用部材２において第１と第２の支持部（４ａ，４ｂ）は同様に同一高さ位置で、ほぼ同一水平面に沿った支持面（６ｘａ、６ｘｂ）上にガラス板材の下隅部を載置しており、同じ段のガラス板材全てが各下端辺をほぼ同一水平線上に沿った状態で支持される。
【００３４】
また、本実施形態のガラス板材支持用部材２を用いたガラス張りカーテンウォール構成のための方立機構全体においては、上記構成を備えたガラス板材支持用部材２が各ガラス板材Ｇの四隅に配置されることとなり、各ガラス板材Ｇはその下方両側に位置する支持用部材２の支持部４によって両側下端隅部が挟持支持され、上方両側に位置する支持用部材２の係止部７によって両側上端隅部が係止され、それぞれ所定位置でカーテンウォールの構成要素として支持される。
【００３５】
このようなガラス板材Ｇに対して風圧等の外力が作用して、例えば左右のガラス板材Ｇに垂直方向の層間変位が発生した場合には、図３に示すように、左右いずれかの列のガラス板材が上方へ移動することがあるが、本実施形態の方立機構によれば、各ガラス板材は常に安定な支持状態が維持される。
【００３６】
例えば図３（ａ）に示すように右列のガラス板材が上方に移動すると、基台部３の下方のガラス板材Ｇｄの左上隅部が第１の支持部４ａを押し上げるが、第１の支持部４ａは支軸５ａを中心に回動可能であると共に、支軸５ａを支えるロッキング部材１０の一方の軸支部１２ａも他方の軸支部１２ｂを回転中心にして上方へ回動可能であるため、第１の支持部４ａはガラス板材Ｇａと一体的に上方へ移動でき、常に載置部６ａの支持面６ｘａをガラス板材Ｇａの左下隅部の下端辺に当接させたままで安定に支持することができると同時に、下方のガラス板材Ｇｄの左上隅部も第１の支持部４ａの下部の係止部７ａ内で安定に挟持される。
【００３７】
また、図３（ｂ）に示すように左列のガラス板材が上方に移動して、基台部３の下方のガラス板材Ｇｃの右上隅部が第２の支持部４ｂを押し上げても、第２の支持部４ｂが支軸５ｂを中心に軸回動可能であると共に支軸５ｂを支えるロッキング部材１０の他方の軸支部１２ｂが一方の軸支部１２ａを回転中心として上方へ回動可能であるため、第２の支持部４ｂはガラス板材Ｇｂと一体的に上方へ移動でき、載置部６ｂの支持面６ｘｂをガラス板材Ｇｂの右下隅部の下端辺に当接させたまま常に安定な支持状態を維持できると同時に、下方のガラス板材Ｇｃの右上隅部も第２の支持部４ｂの下部の係止部７ｂ内で安定に挟持される。
【００３８】
従って、層間変位により右列または左列のガラス板材が上方へ移動しても、いずれのガラス板材（Ｇａ，Ｇｂ，Ｇｃ，Ｇｄ）にも局所的な負荷は生じず、各隅部は対応する支持部の載置部あるいは係止部により安定に支持される。
【００３９】
さらに、層間変位としては、上記のような垂直方向の上下動だけでなく、各ガラス板材が前記開口面方向に沿って時計回りあるいは逆時計回りに回転変位する場合もある。この場合、ガラス板材の下隅部はそれぞれ上下方向に移動しつつガラス下端辺が水平方向に対して傾斜するという複雑な変位を生じるが、本実施形態のガラス板材用支持部材２によれば、このような支持対象のガラス板材下隅部の複雑な変位に対応して良好に安定な支持状態を維持できる。
【００４０】
例えば、図４（ａ）に示すように、ガラス板材（Ｇａ，Ｇｂ）がそれぞれ時計回り方向へ回転変位した場合には、左側のガラス板材Ｇｂの下端辺は右下隅部が下向きで（不図示の左下隅部が上方向に移動して）傾斜し、右側のガラス板材Ｇａの下端辺は左下隅部が上方向に移動して（不図示の右下隅部が下向き）で傾斜する。
【００４１】
これに対して、第２の支持部４ｂは左側ガラス板材Ｇｂの右下隅部の回転に伴って同じ角度だけ支軸５ｂおよび軸支部１２ｂを回転中心として時計回り方向に回動し、その載置部６ｂの支持面６ｘｂもガラス板材Ｇｂの右下隅部の下端辺と同じ傾斜とすることができるため、該下端辺に対する支持面６ｘｂの当接領域が小さくなることなく良好な当接支持状態は維持される。
【００４２】
一方、第１の支持部４ａは、支軸５ａおよび軸支部１２ａを回転中心とした時計回り方向への回動と、ロッキング部材１０自身の軸支部１２ａ側の他方の軸支部１２ｂを回転中心とした上方への回動とによって、右側ガラス板材Ｇａの左下隅部と同じだけ上方に移動する共に同じ角度だけ時計回り方向に回動し、その載置部６ａの支持面６ｘａもガラス板材Ｇａの左下隅部の下端辺と同じ高さ位置で同じ傾斜とすることができるため、該下端辺に対する支持面６ｘｂの当接領域が小さくなることなく良好な当接支持状態が維持される。
【００４３】
またこれとは逆に、図４（ｂ）に示すようにガラス板材（Ｇａ，Ｇｂ）がそれぞれ逆時計回り方向へ回転した場合には、第１の支持部４ａは右側ガラス板材Ｇａの左下隅部の回転に伴って同じ角度だけ支軸５ａおよび軸支部１２ａを回転中心として逆時計回り方向に回動し、その載置部６ａの支持面６ｘａもガラス板材Ｇａの左下隅部の下端辺と同じ傾斜となって、該下端辺に対する支持面６ｘａの良好な当接支持状態は維持される。
【００４４】
さらに第２の支持部４ｂは、支軸５ｂおよび軸支部１２ｂを回転中心とした逆時計回り方向への回動と、ロッキング部材１０自身の軸支部１２ｂ側の他方の軸支部１２ａを回転中心とした上方への回動とによって、左側ガラス板材Ｇｂの右下隅部と同じだけ上方に移動すると共に同じ角度だけ逆時計回り方向に回動し、その載置部６ｂの支持面６ｘｂもガラス板材Ｇｂの右下隅部の下端辺に対して、同じ高さ位置で同じ傾斜とすることができるため、該下端辺に対して良好な当接支持状態が維持される。
【００４５】
以上のように、層間変位において、各ガラス板材に時計回りあるいは逆時計回りの回転が生じても、本実施形態によるガラス板材支持用部材によれば、各支持部は支持対象のガラス板材の下隅部と一体的に移動、回動でき、常に支持部の支持面がガラス板材の隅部下端辺に良好に当接して、ガラス板材に局所的な負荷を作用させることなく安定な支持状態が維持できる。
【００４６】
また、以上のようなロッキング部材１０とその軸受（１１ａ，１１ｂ）および第１と第２の支持部（４ａ，４ｂ）とその支軸（５ａ，５ｂ）とから構成されるクランク機構のような軸回転機構によって、地震の際にも第１と第２の支持部（４ａ，４ｂ）は左右にスイングして振動や衝撃を吸収しつつ、ガラス板材と一体的に揺動できるので、ガラス部材が地震の振動で載置面上を飛びはねて衝突したりして破損を生じる危険は回避される。
【００４７】
なお本実施形態においては、基台部３の屋外側下方に載置台１３を形成しておいた。この載置台１３は、平常時に基準位置でガラス板材を支持する第１と第２の支持部（４ａ，４ｂ）の屋内側下端を下方から支承し、左右二つのガラス板材（Ｇａ，Ｇｂ）の自重を支持するものである。これによって、平常時には第１と第２の支持部（４ａ，４ｂ）を軸支するロッキング部材１０と支軸（５ａ、５ｂ）にのみ荷重をかけることなく、ガラス板材（Ｇａ，Ｇｂ）の自重をより安定的に支持することができる。
【００４８】
また、第１および第２の支持部（４ａ，４ｂ）の載置部（６ａ，６ｂ）と係止部（７ａ，７ｂ）の、それぞれガラス板材と接触する内壁面領域には、樹脂材等からなる緩衝部材としてのガラスライナーＬを設けておくことが望ましい。
【００４９】
【発明の効果】
以上説明したとおり、本発明のガラス板材支持用部材によれば、各支持部は左右のガラス板材の各種層間変位に対応して、ガラス板材に局部的応力を生じせしめることなく常に安定的に安全に支持できるという効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a vertical mechanism for supporting, for example, glass or a plate material used when a glass-walled curtain wall is constructed.
[0002]
[Prior art]
In recent years, glass curtain walls in which walls such as halls of buildings and public facilities are made of only glass have become widespread due to an improvement in the feeling of opening of buildings and the improvement of daylighting, or appearance design. Such a glass-clad curtain wall covers an opening of a building with a plurality of glass plates, and each glass plate is supported by a vertical mechanism using a dedicated support member.
[0003]
Conventionally, as a vertical mechanism, an upper frame and a lower frame are attached to the ceiling and floor of the opening, respectively, and a columnar vertical body disposed between the upper and lower frames is made of glass. A plurality of support members are installed in the horizontal direction at intervals corresponding to the width of the plate material, and a plurality of support members are attached to the vertical direction of each vertical body at intervals corresponding to the height of the glass plate material. In general, the lower end corner of the plate is supported on each of the left and right sides.
[0004]
In this vertical mechanism, each glass plate material is configured such that both sides of the lower end are placed and supported on a support member disposed on the left and right vertical bodies, and usually both sides of the upper end of the glass plate material. Is locked at the lower part of the support member located at the upper left and right to support both sides of the lower end of the upper glass sheet.
[0005]
In such a curtain wall, each glass plate material is exposed to the outside air, and is directly subjected to external force effects such as wind pressure due to strong winds and vibration due to earthquakes, so that the glass plate material is subject to fluctuations such as vertical movement and rotation, so-called interlayers. Cause displacement. Therefore, the vertical mechanism must be able to stably support the glass plate material even if such interlayer displacement occurs.
[0006]
Then, the thing of the structure which the glass mounting part of a supporting member can move with the interlayer displacement of glass is considered. For example, Japanese Patent No. 2922510 discloses that when an interlayer displacement occurs, the glass placing portion can move in the vertical direction within a range above a predetermined support position.
[0007]
[Problems to be solved by the invention]
However, the interlayer displacement of the glass plate material may not only move up and down in the vertical direction but also rotate. In this case, in the conventional vertical mechanism as described above, the lower end side of the corner portion of the glass plate material is inclined with respect to the glass placement portion along the horizontal direction, and the contact support area with the placement portion is reduced to reduce the glass. Local stress acts on This local load can cause glass breakage.
[0008]
Accordingly, in order to maintain the stability and safety of the glass curtain wall over a long period of time, a vertical mechanism capable of supporting the glass plate material stably and constantly adapting to the interlayer displacement is desired.
[0009]
In view of the above problems, the object of the present invention is to support a glass plate material that can always stably and safely support the glass plate material without causing a local load on the glass plate material in response to various interlayer displacements of the glass plate material. Is to provide. In particular, it is an important object of the present invention to provide a support member for a vertical mechanism that can cope with displacement in the rotational direction (or complicated in the lateral direction, twist direction, etc.). For example, it is also an object of the present invention to provide a glass plate material support member that can stably support a glass plate material without causing a decrease in the contact area of the support surface with respect to the glass plate material even when various interlayer displacements occur. is there.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, in the invention according to claim 1, in order to form a wall surface by attaching a plurality of glass plate materials to an opening of a building, a vertical direction of the opening is formed in the structure of the building. A glass plate material supporting member that is fixed at a predetermined height position of a column-shaped vertical body disposed on and supports two glass plate materials that are disposed adjacent to each other with the vertical body interposed therebetween. The member includes a base portion having a fixing portion fixed to the vertical body, a first support portion on which one lower left corner portion of the two glass plate materials is placed, and a lower right corner of the other glass plate material. A second support part on which the part is placed, and a locking member that couples the two support parts, and the locking member is arranged in a bilaterally symmetrical position across the center line of the support member. Each of the two support portions along the opening surface direction. While being pivotally supported in a pivotable state and being in a reference position when supporting the two glass plate materials, the two pivotal support portions are supported and held by the base portion from below, respectively. It is characterized in that it is installed on the base part in such a manner that one of the two supporting parts is pivoted about the other pivotal support part.
[0011]
According to a second aspect of the present invention, there is provided the glass plate material supporting member according to the first aspect, wherein the base portion is the predetermined two supporting portions, and the two glass portions are the glass. It is further characterized by further comprising a mounting table for supporting the two support portions from below in a state of being in a reference position for supporting the plate material.
[0012]
The support member of the present invention is used by being fixed to a columnar vertical body, and supports the lower end corners of the glass plate material arranged left and right around the vertical body. The first support portion and the second support portion are provided on a base portion having a fixing portion fixed to the vertical body so as to be rotatable via a locking member. Supports the lower left corner of the glass plate placed on the right side with a support (for example, the right support), and supports the lower right corner of the left glass plate with a second support (for example, the left support). It is. In order to stably support the glass plate material, the support portion preferably holds the lower corner portion of the glass plate material from the front and rear.
[0013]
In the present invention, the first and second support portions are pivotally supported by the locking member so as to be rotatable on the opening surface of the building, and the respective positions are symmetrical with respect to the central portion. Is arranged. This is because the support force is equally applied to the left and right support portions.
[0014]
The support portion itself is pivotally supported so as to be able to swing in the lateral direction. In addition, the locking member itself supporting each support portion is configured to be rotatable about each of the two shaft support portions of each support portion, with one shaft support portion as the rotation center, The other shaft support side is rotatable (using the locking member itself as an arm).
[0015]
Therefore, for example, when the pivot member pivotally supporting the right support portion of the locking member is pivoted, the left support portion side of the locking member pivots clockwise with the locking member itself as an arm. In conjunction with this, the left support portion also rotates in the clockwise direction. Conversely, when the left pivotal support of the locking member is used as a fulcrum, the right pivotal support side rotates counterclockwise with the locking member as an arm, and the right support is also counteracted. Rotate clockwise.
[0016]
In other words, the shaft support itself is pivotally supported by the locking member (also at the same time as the support portion) so as to be rotatable, and the crank using the locking member as an arm in a clockwise direction (or counterclockwise direction). Since it can be rotated like a mechanism, it is possible to allow not only lateral movement and vertical movement, but also these combined movements.
[0017]
According to the glass plate material supporting member of the present invention as described above, for example, when the glass plate material is displaced not only in the vertical direction but also in the clockwise or counterclockwise rotational direction along the opening surface direction. In addition, the first and second support portions are formed on the right side caused by the rotational displacement of the two glass plates due to the rotation about the shaft support portion of the support portion itself and the rotation of the locking member such as a crank mechanism. The movement of the lower left corner of the glass plate and the movement of the lower right corner of the left glass lower material are allowed, and the glass plate can be rotated and moved integrally with the lower corner of each glass plate to be supported. Accordingly, the glass support surfaces of the first and second support portions can maintain a good contact support state without substantially reducing the contact region with respect to the lower end side of the lower corner portion inclined with the rotation of the glass plate material. The glass plate material can always be stably and safely supported without causing a local load on the glass plate material.
[0018]
Thus, since the displacement according to the glass plate material of the first and second support portions is due to the shaft rotation mechanism, the displacement operation is smooth with little friction, and the burden on the support shaft portion due to the displacement motion is small. . In addition, these two support parts can swing left and right in the event of an earthquake to absorb vibrations and shocks by the rotation of their own shaft and the rotation of a locking member such as a crank mechanism, and swing together with the glass plate. Therefore, the risk of breakage due to the glass member jumping and colliding with the support surface due to the vibration of the earthquake is avoided.
[0019]
For example, when an external force is applied to the glass member in a horizontal and lateral direction, the support portion is made of a glass plate material so that the glass plate material does not slide and move on the support surface to reduce the support area. What is necessary is just to set it as the structure which can regulate horizontal / horizontal movement of this from both lower sides.
[0020]
For example, if a vertical surface that is perpendicular to the support surface on which the lower end of the glass is placed is further provided as a stopper on the glass side surface, the support portion is contacted with the support surface and this vertical surface in an L-shape at the lower glass corner. It can be supported in close contact, and the horizontal and horizontal movement of the glass plate material can be restricted by the support portions on the left and right sides.
[0021]
Further, as described in claim 2, when the two support portions are at a reference position for supporting the two glass plate members, a mounting table for supporting the two support portions from below is provided on the base portion. If this is the case, during normal times when no interlayer displacement occurs, the weight of the glass plate material is supported more stably by this mounting table without the load being concentrated on the shaft portion that pivotally supports the first and second support portions on the locking member. it can.
[0022]
In addition, it cannot be overemphasized that the member for glass plate material support by this invention can be utilized for support members, such as not only a standing mechanism for glass-clad curtain walls but a board | plate material and various panels.
[0023]

[0025]
The present glass plate material supporting member 2 includes a base portion 3 having a fixing portion (20, 21) fixed by bolting or the like at a predetermined height position of the vertical body 1, and one lower left corner of two glass plate materials. The first support part 4a on which the part is placed, the second support part 4b on which the lower right corner of the other glass plate material is placed, and the first and second support parts (4a, 4b) are connected. The locking member 10 is mainly composed.
[0026]
The locking member 10 is supported in a state that the first and second support portions (4a, 4b) are pivotally supported along the opening surface direction at symmetrical positions from the center portion of the support member 2, respectively. The first and second support portions (4a, 4b) are connected to each other so that an equal supporting force acts on the base portion 3, and these support portions are connected to the base portion 3. To be connected.
[0027]
Specifically, the lower portion of the locking member 10 is fitted and installed in the groove portion 9 provided on the outdoor side of the base portion 3, and is bilaterally symmetrical with the center line of the supporting member 2 sandwiched in the upper region. The shaft support portions (12a, 12b) provided with bearings (11a, 11b) that support the shaft 5a of the first support portion 4a and the support shaft 5b of the second support portion 4b so as to be rotatable are formed at the positions. .
[0028]
These shaft support portions (12a, 12b) have a substantially cylindrical shape that is fitted and supported by a substantially semicircular concave support portion (8a, 8b) formed at the upper end edge of the groove portion 9 of the base portion 3 on the outdoor side. As shown in FIG. 2, rolling on the surface of the support portion (8 a, 8 b) and sliding on one shaft support portion (12 a or 12 b), the other shaft support portion (12 b or 12 a) side is the support portion. It can be turned upward from (8a, 8b).
[0029]
The first support portion 4a supports the lower left corner of one glass plate material Ga of the two glass plates, and the second support 4b supports the lower right corner of the other glass plate Gb. The mounting portions (6a, 6b) each have a support surface (6xa, 6xb) on which the lower corners of the corners of the glass plate material to be supported are placed, and a side cross-section so that the glass plate material can be sandwiched from the front and back thereof. The shape is an upward cono shape. In the present embodiment, the first and second support portions (4a, 4b) have a predetermined interval as shown from the shaft support portions (12a, 12b) to the support surfaces (6xa, 6xb), respectively. ing. That is, the support surface (6xa, 6xb) portion is suspended from the shaft support portion (12a, 12b) so as to be rotatable.
[0030]
Further, a vertical surface (6ya, 6yb) orthogonal to the support surface (6xa, 6xb) is further provided near the center of the base portion 3 of each placement portion (6a, 6b), and the horizontal and horizontal directions of the glass plate material are provided. It functions as a stopper that restricts movement in the direction.
[0031]
The first and second support portions (4a, 4b) are provided with locking portions (7a, 7b) each having a cono-shape with a downward-facing side cross section at the lower portion of the placement portion (6a, 6b). The upper left corner and the upper right corner of the two left and right glass plate materials G are respectively fitted, and are held and locked from the front and rear.
[0032]
The first and second support portions (4a, 4b) as described above are respectively supported on the bearings (11a, 11b) of the corresponding shaft support portions (12a, 12b) of the locking member 10 by the support shafts (5a, 5b). The shaft is pivotably supported. That is, the first and second support portions (4a, 4b) themselves are rotatable, and the shaft support portions (12a, 12b) themselves are also rotatable with respect to the locking member 10 and the support portion, and the locking members. 10 can rotate in the clockwise or counterclockwise direction on the other shaft support (12b or 12a) around the one shaft support (12a or 12b) as the center of rotation like a crank mechanism having itself as an arm. Each of the first and second support portions (4a, 4b) can allow not only lateral swinging and vertical movement, but also combined movement thereof.
[0033]
In the normal state, as shown in the front view of FIG. 1C, the lower left corner of the right glass plate and the lower right corner of the left glass plate Gb are positioned symmetrically with respect to the center of the base 3. The mounting portions (6a, 6b) of the first and second support portions (4a, 4b) are stably supported at the same height position, that is, the reference position with equal left and right support forces. At this time, the first and second support portions (4a, 4b) are similarly at the same height in all the glass plate material support members 2 in the same step, and support surfaces (6xa, 6xb) substantially along the same horizontal plane. The lower corner portion of the glass plate material is placed on the top, and all the glass plate materials in the same step are supported in a state where each lower end side is substantially along the same horizontal line.
[0034]
In addition, in the entire vertical mechanism for the glass-walled curtain wall configuration using the glass plate material support member 2 of the present embodiment, the glass plate material support members 2 having the above configuration are arranged at the four corners of each glass plate material G. Thus, each glass plate G is sandwiched and supported at the lower end corners by the support portions 4 of the support member 2 located on both lower sides thereof, and the upper ends of both sides by the locking portions 7 of the support members 2 located on both upper sides. The corners are locked and supported as a component of the curtain wall at each predetermined position.
[0035]
When an external force such as wind pressure acts on such a glass plate G and a vertical interlayer displacement is generated in the left and right glass plates G, for example, as shown in FIG. Although a glass plate material may move upward, according to the vertical mechanism of this embodiment, each glass plate material always maintains a stable support state.
[0036]
For example, as shown in FIG. 3A, when the glass plates in the right row move upward, the upper left corner of the glass plate Gd below the base portion 3 pushes up the first support portion 4a. Since the portion 4a can be rotated about the support shaft 5a, and one shaft support portion 12a of the locking member 10 that supports the support shaft 5a can also be rotated upward about the other shaft support portion 12b. The first support portion 4a can move upward integrally with the glass plate material Ga, and always support the support surface 6xa of the placement portion 6a in a stable manner while being in contact with the lower end side of the lower left corner of the glass plate material Ga. At the same time, the upper left corner of the lower glass plate Gd is also stably held in the locking portion 7a below the first support portion 4a.
[0037]
Further, as shown in FIG. 3B, even if the glass plates in the left row move upward and the upper right corner of the glass plate Gc below the base 3 pushes up the second support 4b, The second support portion 4b can pivot about the support shaft 5b, and the other shaft support portion 12b of the locking member 10 that supports the support shaft 5b can rotate upward about the one shaft support portion 12a. Therefore, the second support portion 4b can move upward integrally with the glass plate material Gb, and is always stably supported with the support surface 6xb of the placement portion 6b being in contact with the lower right edge of the lower right corner of the glass plate material Gb. At the same time that the state can be maintained, the upper right corner of the lower glass plate Gc is also stably held in the locking portion 7b at the lower portion of the second support portion 4b.
[0038]
Therefore, even if the glass plates in the right or left row move upward due to the interlayer displacement, no local load is generated on any of the glass plates (Ga, Gb, Gc, Gd), and each corner corresponds. It is stably supported by the mounting portion or the locking portion of the support portion.
[0039]
Further, as the interlayer displacement, not only the vertical movement as described above, but also each glass plate material may be rotationally displaced clockwise or counterclockwise along the opening surface direction. In this case, the lower corner portion of the glass plate material moves in the vertical direction, causing a complicated displacement in which the lower end side of the glass is inclined with respect to the horizontal direction. According to the support member 2 for glass plate material of the present embodiment, It is possible to maintain a good and stable support state corresponding to the complicated displacement of the lower corner of the glass plate material to be supported.
[0040]
For example, as shown in FIG. 4 (a), when the glass plates (Ga, Gb) are rotationally displaced in the clockwise direction, the lower right corner of the left glass plate Gb is directed downward (not shown). And the lower left corner of the right glass sheet Ga is inclined when the lower left corner moves upward (the lower right corner (not shown) faces downward).
[0041]
On the other hand, the second support portion 4b rotates clockwise around the support shaft 5b and the shaft support portion 12b by the same angle as the lower right corner portion of the left glass plate Gb rotates, and its mounting Since the support surface 6xb of the part 6b can also have the same inclination as the lower end side of the lower right corner of the glass plate material Gb, the contact area of the support surface 6xb with respect to the lower end side is not reduced, Maintained.
[0042]
On the other hand, the first support portion 4a rotates in the clockwise direction with the support shaft 5a and the shaft support portion 12a as the center of rotation, and the other shaft support portion 12b on the shaft support portion 12a side of the locking member 10 itself as the center of rotation. The upward rotation of the right glass sheet material Ga moves upward as much as the lower left corner of the right glass sheet material Ga and rotates clockwise by the same angle, and the support surface 6xa of the mounting portion 6a is also made of the glass sheet material Ga. Since the same inclination can be obtained at the same height position as the lower end side of the lower left corner, a good contact support state is maintained without reducing the contact area of the support surface 6xb with respect to the lower end side.
[0043]
On the other hand, when the glass plates (Ga, Gb) are rotated in the counterclockwise direction as shown in FIG. 4B, the first support portion 4a has the lower left corner of the right glass plate Ga. Along with the rotation of the part, the support shaft 6xa of the mounting part 6a is rotated in the counterclockwise direction around the support shaft 5a and the support part 12a by the same angle as the rotation center, and the lower left side of the lower left corner of the glass plate material Ga. With the same inclination, a good contact support state of the support surface 6xa with respect to the lower end side is maintained.
[0044]
Further, the second support portion 4b rotates in the counterclockwise direction around the support shaft 5b and the shaft support portion 12b and the other shaft support portion 12a on the shaft support portion 12b side of the locking member 10 itself as the rotation center. As a result of the upward rotation, the upper glass plate Gb moves upward as much as the lower right corner of the left glass plate Gb and rotates counterclockwise by the same angle, and the support surface 6xb of the mounting portion 6b also moves to the glass plate Gb. Since the same inclination can be made at the same height position with respect to the lower end side of the lower right corner portion, a good contact support state is maintained with respect to the lower end side.
[0045]
As described above, in the interlayer displacement, even if clockwise or counterclockwise rotation occurs in each glass plate material, according to the glass plate material supporting member according to the present embodiment, each support portion is a lower corner of the glass plate material to be supported. The support surface of the support part is always in good contact with the lower edge of the corner of the glass plate, and a stable support state is maintained without applying a local load to the glass plate. it can.
[0046]
Further, such as a crank mechanism constituted by the locking member 10 and the bearings (11a, 11b) and the first and second support portions (4a, 4b) and the support shafts (5a, 5b) as described above. The shaft rotation mechanism allows the first and second support portions (4a, 4b) to swing left and right and absorb vibrations and shocks in the event of an earthquake, and can swing integrally with the glass plate material. The risk of causing damage by jumping on the mounting surface due to the vibration of the earthquake and colliding with it is avoided.
[0047]
In the present embodiment, the mounting table 13 is formed below the base unit 3 on the outdoor side. The mounting table 13 supports the lower ends on the indoor side of the first and second support portions (4a, 4b) that support the glass plate material at the reference position in the normal state from below, and the two left and right glass plate materials (Ga, Gb). Supports its own weight. Accordingly, the weight of the glass plate material (Ga, Gb) is not applied to the locking member 10 and the support shafts (5a, 5b) that support the first and second support portions (4a, 4b) in normal times. Can be supported more stably.
[0048]
In addition, a resin material or the like is provided on the inner wall surface regions of the placement portions (6a, 6b) and the locking portions (7a, 7b) of the first and second support portions (4a, 4b) that are in contact with the glass plate materials, respectively. It is desirable to provide a glass liner L as a buffer member made of
[0049]
【The invention's effect】
As described above, according to the glass plate material supporting member of the present invention, each support portion can correspond to various interlayer displacements of the left and right glass plate materials, and always stably and safely without causing local stress in the glass plate material. There is an effect that can be supported.
