Description

【0001】
【発明の属する技術分野】
この発明は、窓ガラス、間仕切り用パネル等の板材を支持するための板材の支持構造に関する。
【0002】
【従来の技術】
一般に、躯体の開口部に配置された多数の窓ガラスを支持する場合には、躯体の開口部に複数の方立が左右方向へ所定の間隔をもって立設される。各方立には、複数の載置部が上下方向へ所定間隔をもって設けられる。そして、隣接する二つの方立の同一高さに配置された載置部に窓ガラスの左右の下端部を載置することにより、窓ガラスが支持されるようになっている。
【0003】
載置部は、窓ガラスを支持するために所定の位置から下方へは移動不能であるが、所定の位置から上側では上下方向へ移動可能になっている。これは、地震等に起因する層間変位によって窓ガラスが回転し、その結果窓ガラスの上端隅部が当該窓ガラスの上側に配置された載置部にぶつかって破損するのを防止するために採用されたものである(例えば、特許文献1参照。)。
【0004】
【特許文献1】
特許第2922510号公報(第3頁、図7)
【0005】
【発明が解決しようとする課題】
上記従来の支持構造では、窓ガラスの左右の下端両隅部が載置によって支持されているだけであるため、窓ガラスの下端両隅部にのみ応力が集中するという問題があった。
【0006】
【課題を解決するための手段】
この発明は、上記の課題を解決するために、躯体に互いに平行に立設された複数の方立と、各方立に所定の支持位置から下方へは移動不能に、かつ上記支持位置より上側の範囲では上下方向へ移動可能に設けられた載置部材とを備え、水平方向に隣接する二つの方立にそれぞれ設けられた二つの載置部材によって板材を支持する板材の支持構造において、水平方向に隣接する二つの方立にそれぞれ設けられた二つの載置部材に横材の両端部をそれぞれ載置し、この横材の上に上記板材を載置したことを特徴としている。
この場合、上記方立が、上記板材より室外側に左右に隣接する二つの板部の互いに隣接する端部と対向するようにして設けられた上下方向に延びる縦押縁を有し、この縦押縁と上記方立の上記板材より室内側に位置する部分との間に、上記板材の左右方向の端部が臨む縦密封空間が形成され、左右に隣接する二つの横材間に上記縦密封空間の下端部を閉じる水受け部が形成され、上記縦押縁には、その下面から上方へ向かって延びる排水孔が形成され、上記縦押縁の室内側を向く面には、室内側の一端開口部が上記水受け部と対向し、他端部が上記排水孔に連通した連通孔が形成されていることが望ましい。
【0007】
【発明の実施の形態】
以下、この発明の一実施の形態について図1〜図8を参照して説明する。これらの図に示す実施の形態は、この発明に係る板材の支持構造を建築物の躯体(図示せず)の開口部に配置された多数の窓ガラス(板材)の支持構造に採用したものである。勿論、この発明は、窓ガラス以外の板材の支持構造にも適用可能である。
【0008】
躯体の開口部は、正面から見た形状が正方形又は長方形をなしており、その内面には開口部に対応した形状の枠体(図示せず)が設けられている。開口部の上面及び下面に沿う枠体の上枠部と下枠部との間には、図1に示す方立1がその長手方向を上下方向に向けて配置されている。方立1の上端部及び下端部は、枠体の上枠部と下枠部とにそれぞれ支持されている。方立1は、複数設けられている。各方立1は、左右方向へ所定の間隔毎に並んで配置されている。
【0009】
図1及び図2に示すように、方立1は、断面長方形の筒状をなす方立本体11を有している。方立本体11の室外O(図4参照)側を向く側面の左右方向における中央部には、室外O側に向かって突出する縦板部12が方立本体11と一体に形成されている。この縦板部12は、方立本体11の全長にわたって延びている。
【0010】
図2に示すように、縦板部11の右方を向く一側面の方立本体11側の端部には、載置部材13が上下方向へ所定の間隔毎に配置されている。載置部材13は、逆L字状をなしており、縦板部12に沿って上下に延びるスライド板部13aと、このスライド板部13aの上端部から右方へ向かって水平に延びる支持板部13bとから構成されている。スライド板部13aは、縦板部12に室内外方向及び左右方向へは移動不能に、上下方向へは移動可能に設けられている。縦板部12の左側面の載置部材13より下側の箇所には、ストッパ14がボルトB1等の固定手段によって固定されている。このストッパ14にスライド板部13aの下端面が突き当たると、載置部材13はそれ以上下方へ移動することができなくなっている。つまり、載置部材13は、ストッパ14より上側においてのみ上下方向へ移動可能になっている。
【0011】
縦板部12の左方を向く左側面には、載置部材13′が設けられている。この載置部材13′は、載置部材13と左右対称である点を除き、載置部材13と同様に構成されており、スライド板部13a及び載置板部13bを有している。しかも、載置部材13′は、載置部材13と同様に、縦板部12の左側面に設けられたストッパ(図示せず)に突き当たることによって下方への移動が阻止され、ストッパより上側においてのみ上下方向へ移動可能になっている。載置部材13′は、室内側方向においては載置部材13と同一位置に配置されており、ストッパに突き当たっているときには、載置部材13と上下方向において同一位置に位置している。
【0012】
左右に隣接する二つの方立1,1の縦板部12,12間には、長手方向を左右方向に向けた横材2が水平に配置されている。横材2は、図4に示すように、断面四角形の筒状をなす本体部21と、この本体部21と一体に形成され、本体部21の室外O側を向く側面から前方へ向かって突出する支持板部22と、この支持板部22の室外O側の端部に支持板部22と一体に形成された水切板部23とを有している。
【0013】
本体部21は、左右に隣接する方立1,1の縦板部12,12の間隔より若干短い長さを有している。したがって、本体部21の端面と縦板部12との間には、隙間が形成されている。本体部21の左端開口部には、一の方立1に設けられた載置部材13の支持板部13bが挿入され、ボルトB2等の固定手段によって固定されている。本体部21の右端開口部には、一の方立1に対して右側に隣接する方立1に設けられた載置部材13′の支持板部13bが挿入され、ボルトB2等の固定手段によって固定されている。この場合、本体部21の両端部が互いに同一高さに配置された載置部材13,13′に固定されているのは勿論である。横材2の両端部は、載置部材13,13′に連結固定されているので、上下方向へ移動可能である。したがって、層間変位によって載置部材13,13′の一方が上方へ移動した場合には、載置部材13又は13′側の一端部を中心として他端部が上方向へ回動する。本体部21の室内I側を向く面は、方立本体11の室外O側を向く面に摺動可能に接触している。
【0014】
支持板部22は、横材2の全長にわたって水平に延びている。支持板部22の上面及び下面は、水平面になっている。図1及び図4に示すように、支持板部22の上面の室外側の端部には、板ガラスからなる窓ガラス(板材)3がシール部材S1を介して載置されている。したがって、窓ガラス3は、層間変位によって載置部材13,13′が相対的に上下方向へ移動すると、横部材2と供に回動変位する。窓ガラス3の上端面は、シール材S2を介して支持板部22の下面に接触している。窓ガラス3の上端面の支持部材22に対する接触箇所は、窓ガラス3の下端面が支持板部22の上面に載置されている箇所と室内外方向において同一箇所になっている。
【0015】
水切板部23は、支持板部22の全長にわたって形成されている。ただし、水切板部23は、図1及び図5に示すように、切欠き部23aが形成されることによって複数に分断されている。切欠き部23aは、左右に隣接する二つの横材2,2間の部分と対向するように配置されている。切欠き23aの左右方向の長さは、横材2,2の間隔より広くなっている。水切板部23の上面は、窓ガラス3の室外O側を向く面を滑り下りた雨水を室外O側へ向かって流すために、室外O側へ向かって下り勾配をなす傾斜面に形成されている。
【0016】
図1に示すように、窓ガラス3より室外O側には、長手方向を上下方向に向けた複数の縦押縁15が一直線上に並んで配置されている。この縦押縁15は、方立1の一部をなすものであり、図1、図4及び図6に示すように、押え部15aと、この押え部15aの室内I側を向く面に押え部15aと一体に形成された連結板部15bとを有している。
【0017】
図1及び図4〜図6に示すように、押え部15aは、厚さの比較的厚い板状をなしており、その長手方向を上下方向に向けるとともに、その幅方向を左右方向に向けて配置されている。押え部15aの内部には、その上端面から下端面まで貫通する排水孔15fが形成されている。この排水孔15fの上端開口部は、栓体15cによって閉じられている。排水孔15fの下端開口部は、下方に向かって開放されている。押え部15aは、その左右方向の中央部が切欠き部23aの左右方向の中央部とほぼ一致するように配置されている。つまり、押え部15aは、その左右方向の中央部が左右に隣接する二つの窓ガラス3,3のほぼ中央に位置するように配置されている。しかも、押え部15aの左右方向の幅は、左右に隣接する二つの窓ガラス3,3の間隔より広く設定されている。したがって、押え部15aの室内I側を向く面の左右両側部は、左右方向に隣接する二つの窓ガラス3,3の室外O側を向く面の左右方向の各側部とそれぞれ対向している。押え部15aは、上下に隣接する二つの横材2の上下方向のピッチより若干短い長さを有している。この結果、上下に隣接する二つの押え部15a,15aは、押え部15aの長さが横材2のピッチより短い分だけ上下方向に互いに離れて配置されている。図4に示すように、上下に隣接する二つの押え部15a,15の間に形成される隙間は、押え部15a,15aの室内I側を向く面間に架け渡された遮蔽部材16によって閉じられている。これにより、風雨が押え部15a,15a間の隙間から室内I側へ入り込むことが防止されている。押え部15aは、上下方向に関してはその下端縁より若干上側の部分が横材2と対向するように配置されている。この結果、押え部15aの下端部は、上下左右に隣接する4枚の窓ガラス3と対向している。
【0018】
図1に示すように、連結板部15bは、押え部15aの室内I側を向く面のほぼ中央部に配置されており、押え部15aの全長にわたって延びている。そして、連結板部15bは、縦板部12に対し、前後方向及び左右方向へは移動不能に連結されている。上下方向に関しては、後述するように、縦板部12に対し所定の位置より下方へは移動不能になっているが、所定位置より上側では上下方向へ移動可能に連結されている。
【0019】
図1に示すように、方立本体11の室外O側を向く面と窓ガラス3との間には、長手方向を上下方向に向けた一対の押圧部材17,17′が配置されている。一対の押圧部材17,17′は、方立1の一部をなすものであり、縦板部12を間にしてその右側と左側とにそれぞれ配置されている。一方の押圧部材17は、断面「コ」字状をなしており、その開放部を縦板部12側に向けた状態で配置されている。そして、縦板部12に室内側方向及び左右方向には移動不能に、上下方向には移動可能に連結されている。押圧部材17の長さは、上下に隣接する横材2,2の間隔より若干短くなっている。図3及び図4に示すように、押圧部材17の下端面は、横部材2の本体部21の上面にシール部材S3を介して載置されており、押圧部材17の下端面と本体部21の上面との間は、シール部材S3によって封止されている。押圧部材17の上端面と本体部21の下面との間は、シール部材S4によって封止されている。他方の押圧部材17′は、一方の押圧部材17と左右対称になっているのでその説明は省略する。勿論、押圧部材17′の下面と横材2の本体部21の上面との間、及び押圧部材17′の上面と横材2の本体部21の下面との間には、シール部材S3、S4がそれぞれ設けられている。押圧部材17,17′の各上下の端面と上下に隣接する横材2,2の各上下の面との間にシール部材S3,S4が設けられることにより、押圧部材17,17′は横材2と一緒に上下方向へ移動するようになっている。
【0020】
図1及び図5に示すように、押え部15aの室内I側を向く面の左右の各側部と、当該各側部に対向する窓ガラス3,3の室外O側を向く面の左右の側部との各間には、シール部材S5がそれぞれ設けられている。シール部材S5は、最も上方に配置された縦押縁15の上端縁から最も下方に配置された縦押縁15の下端縁まで延びており、切欠き部23aの左右方向における端部を上下に貫通している。シール部材S5は、窓ガラス3の下端面と横材2の上面との間に設けられたシール部材S1、及び窓ガラス3の上端面と横材2の下面との間に設けられたシール部材S2と一体的に設けられている。すなわち、図7に示すように、窓ガラス3を室外側から見たとき、シール部材S5は、シール部材S1,S2の各端部と交差しており、当該交差部においてシール部材S5の室内I側を向く面とシール部材S1,S2の室外O側を向く面とが一体的に連続するよう、シール部材S5がシール部材S1,S2と一体に形成されている。この結果、窓ガラス3より室内I側に存する建築物の内部は、シール部材S1,S2,S5,S5によってシールされている。したがって、シール部材S1,S2、S5、S5が劣化してシール性が低下しない限り、窓ガラス3より室外O側の雨水が室内I側に侵入することはない。
【0021】
図1及び図5に示すように、押圧部材17と窓ガラス3との対向面間には、シール部材S6が設けられ、押圧部材17′と窓ガラス3との間にはシール部材S7が設けられている。また、図4に示すように、窓ガラス3の室内I側を向く面の下端部とこれに対向する横材2の本体部21の室外O側を向く面の上端部との間には、シール部材S8が設けられ、窓ガラス3の室内I側を向く面の上端部とこれに対向する横材2の本体部21の室外O側を向く面の下端部との間には、シール部材S9が設けられている。図8に示すように、シール部材S6,S7の上下の各端部は、シール部材S8,S9の左右の両端部とそれぞれ連続して一体に形成されている。この結果、シール部材S6〜S9が窓ガラス3の室内I側を向く面をその周縁部に沿って環状にシールしているので、仮にシール部材S1,S2,S5の劣化によって窓ガラス3より内側に雨水が侵入したとしても、その雨水が窓ガラス3と押圧部材17,17′及び/又は窓ガラス3と横材2との間を通って室内Iに侵入することはない。シール部材S6〜S9は、一体に形成されているが、それぞれ別体に形成し、端部どうしを固着してもよい。
【0022】
ここで、シール部材S5によるシール性が劣化して、押え部15aと窓ガラス3との間から雨水が内部に侵入すると、その雨水は、縦板部12及び押圧部材17,17′を伝わって流れ、押圧部材17,17′と方立本体11との接触面間から室内Iに侵入するおそれがある。そこで、押圧部材17,17′と方立本体11との各接触面間にシール部材S10をそれぞれ設けている。しかも、シール部材S10の下端部をシール部材S3の室内I側の端面に押圧接触させるとともに、シール部材S10の上端部をシール部材S4の室内I側の端面に押圧接触させている。これにより、方立本体11と押圧部材17,17′の各間から雨水が室内Iに侵入するのを防止している。勿論、シール部材S10は、方立本体11の上端から下端まで延びている。
【0023】
上記のようなシール構造が採用されることにより、二つの横材2,2の左右に隣接する端部と、当該二つの横材2,2に対して上側又は下側に隣接する二つの横材2,2の左右に隣接する端部との間には、方立本体11、押圧部材17,17′、窓ガラス3,3及び縦押縁15(押え部15a)並びにシール部材S1〜S10により上下方向に延びる縦密封空間M1が形成される(特に、図1及び図5参照)。この縦密封空間M1は、室内I及び室外Oに対して密封されている。縦密封空間M1の下端部は、図4に示すように、横材2の支持板部22の上面、横材2の支持板部22より上側に位置する室外O側を向く面、窓ガラス3及びシール部材S1,S8によって形成される水平方向に延びる下側横密封空間M2に連通し、縦密封空間M1の上端部は、横材2の支持板部22の下面、横材2の支持板部22より下側に位置する室外O側を向く面、窓ガラス3及びシール部材S2,S9によって形成される水平方向に延びる上側横密封空間M3に連通している。しかし、下側横密封空間M2及び上側横密封空間M3は、室内I及び室外Oに対して密封されている。したがって、縦密封空間M1は、上下の横密封空間M2,M3に連通してるものの、室内I及び室外Oに対しては密封されている。
【0024】
なお、シール部材S1のシール性が劣化すると、室外I側の雨水が窓ガラス3の下端面と支持板部22の上面との間から下側横密封空間M2に雨水が侵入することがあるが、この雨水が下側横密封空間M2から室内Iに侵入することはない。この点は、上側密封空間M3に侵入した雨水も同様である。
【0025】
図2、図4及び図6に示すように、縦板部12には、その室外O側の先端面から方立本体1まで達する切欠き部12aが形成されている。この切欠き部12aは、左右方向に隣接する二つの横材2,2に対応する位置に配置されている。切欠き部12aの上端は、横材2の上端より上側に位置し、下端は横材2の下端より上側ではあるが、支持板部22より下側に位置している。図4及び図6に示すように、縦押縁15の連結板部15bの下端部には、その先端面(室内I側の面)から押え部15aまで達する切欠き部15dが形成されている。この切欠き部15dの上下方向における長さは、切欠き部12aの長さより長くなっており、切欠き部15dの上下方向における中間部が切欠き部12aと対向している。したがって、切欠き部15dの上端を区画する面(下方を向く面)は、切欠き部12aより上側に位置している。切欠き部15dの上端を区画する面は、通常は、切欠き部12aに螺合固定されたねじ部材B3に突き当たっている。このときの縦押縁15の位置が前述した所定の位置であり、縦押縁15は縦板部12に対して所定の位置から下方へは移動不能になっている。縦押縁15は縦板部12に対して所定の位置より上方に位置しているときには、上下方向へ移動可能になっている。なお、切欠き部15dは、連結板部15bの下端まで延びている。
【0026】
切欠き部12a,15dが形成されることにより、左右に隣接する横材2,2の端面どうしが、切欠き部12a,15dを介して互いに対向している。図3に示すように、各横材2の対向する各端面には、端板24が接着、溶接等の固定手段によって水密状態で固定されている。端板24の室内外方向の長さは、本体部21の室内I側の面から支持板部22の室外O側の面までの距離と等しく設定されている。端板24の上面は、室内外方向のいずれの箇所においても横材2の上面より若干上側に位置している。端板24の上面のうちの本体部21に対応する箇所は、室内I側から室外O側へ向かって下り勾配をなす傾斜面に形成されている。端板24の上面のうちの支持板部22に対応する箇所は、水平面になっている。この結果、端板24の上面は、階段状をなしている。端板24の上面は、横材2の対応する各部の上面と同一位置に位置させてもよい。端板24の下面は、支持板部22の下面とほぼ同一平面上に位置している。
【0027】
端板24,24間には、シール部材4が設けられている。シール部材4は、端板24,24間の隙間全体にわたって充填されている。これにより、端板24,24間の隙間、換言すれば、左右に隣接する横材2,2の本体部21の室内I側の面から支持板部22の室外O側の面までの間に形成される隙間が、シール部材4によってシールされている。シール部材4は、端板24,24間の隙間全体にわたって充填されているので、左右方向から見たとき端板24と同一寸法、同一形状に形成されている。しかも、シール部材4は、左右に隣接する横板2,2が相対的に上下方向へ移動したときに、その移動を許容し得るだけの弾性を有している。したがって、横材2,2の上下方向への移動によってシール部材4が破損することはない。
【0028】
図1及び図4〜図6に示すように、縦押縁15の押え部15aとこの押え部15aに切欠き部23aを介して対向する支持板部22との対向面間には、シール部材5が設けられている。シール部材5の室内外方向における幅は、支持板部22と押え部15aとの対向面間の距離と同一に設定されており、左右方向の長さはシール部材S5,S5間の距離と同一に設定されている。この結果、シール部材5は、室内外方向においては、支持板部22の室外O側を向く面、窓ガラス3の室外O側を向く面、及び押え部15aの室内I側を向く面にそれぞれシール状態で接触し、左右方向においてはシール部材S5,S5の対向する内側の各面にシール状態で接触している。シール部材5の上面は、支持板部22の上面と同一平面上に位置させられている。
【0029】
シール部材4,5が設けられることにより、左右に隣接する二つの横材2,2の上方に延びる縦密封空間M1の下端部が閉じられている。すなわち、縦密封空間M1は、シール部材S3より内側(縦密封空間M1の内側)に位置する横材2の本体部21及び支持板部22、端板24、シール部材4及びシール部材5によって閉じられており、それらによって水受け部6(図1、図5参照)が構成されている。したがって、仮にシール部材S5のシール性が劣化して押え部15aと窓ガラス3との間から雨水が縦密封空間M1内に入り込んだ場合、その雨水は縦密封空間M1に臨むいずれかの部材の内面を滑り下りて水受け部6によって受け止められ、それ以上下方へ向かうことはない。また、仮にシール部材S1のシール性が劣化して支持板部22の上面と窓ガラス3の下面との間から室外O側の雨水が下側横密封空間M2に侵入した場合、その雨水は支持板部22の上面を流れ、縦密封空間M1に至る。この場合、支持板部22の上面を流れる雨水は、シール部材S8、S6又はシール部材S8,S7の下側を流れて縦密封空間M1に至る。さらに、シール部材S2のシール性が劣化して支持板部22の下面と窓ガラス3の上面との間から室外O側の雨水が上側横密封空間M3に侵入した場合、その雨水はシール部材S9又は上側横密封空間M3に臨む横材2の内面上を流れて縦密封空間M1に至る。このように、室外Oに面するシール部材S1,S2,S5のいずれのシール性が低下して室外Oの雨水窓ガラス3よりが室内I側に侵入した場合であっても、その雨水は縦密封空間M1に至り、水受け部6によって受け止められる。
【0030】
押え部15aには、その室内I側を向く面から内面まで貫通する連通孔15eが形成されている。この連通孔15eは、その一部がシール部材5の上面と対向するように配置されている。したがって、縦密封空間M1から水受け部6上に至った雨水は、シール部材5から連通孔15eを通って排水孔15f内に流入する。排水孔15f内に入った雨水は、その下端開口部から外部に放出される。
【0031】
上記構成の窓ガラス3の支持構造によれば、載置部材13,13′に横材2の両端部を載置し、この横材2の上に窓ガラス3を載置しているから、層間変位によって窓ガラス3の上端隅部が破損するのを防止することができるのは勿論のこと、横材2が窓ガラス3の下端面をその全長にわたって支持する。したがって、窓ガラス3の下端部に応力が集中することがなく、応力を窓ガラス3全体にわたって一様に作用させることができる。
【0032】
また、この実施の形態の支持構造においては、外部に面するシール部材S1,S2,S5のシール性が劣化し、その結果室外Oの雨水が縦密封空間M1、上下の横密封空間M2,M3に入り込んだとしても、それらの雨水が水受け部6によって受け止められる。そして、連通孔15eから押え部15aの内部に入り込み、押え部15aの下端開口部から外部に放出される。ここで、仮に水受け部6、連通孔15a及び押え部15aの内部による排水路が形成されていなかったものとすると、侵入した全ての雨水が方立1内を通って建築物の最下層まで流れるため、最下層において多量の水が溜まり、それが室内に侵入するおそれがある。この点、この実施の形態では、左右に隣接する横材2,2間に水受け部6が設けられているので、窓ガラス3より室内I側に侵入した雨水は、水流し部6によって受け止められて外部に排出され、建築物の最下層まで流れることがない。したがって、最下層において雨水が室内Iに侵入するのを確実に防止することができる。
【0033】
なお、この発明は、上記の実施の形態に限定されるものでなく、適宜変更可能である。
例えば、上記の実施の形態においては、排水孔15fを押え部15aの上端面から下端面まで貫通させているが、押え部15aの下端面から連通孔15eまで延びる孔として形成してもよい。
【0034】
【発明の効果】
以上説明したように、この発明によれば、窓ガラスの下端隅部に応力が集中するのを防止することができるという効果が得られる。

[0007]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described below with reference to FIGS. In the embodiments shown in these drawings, the support structure for a plate material according to the present invention is adopted for a support structure for a large number of window glasses (plate materials) arranged in an opening of a housing (not shown) of a building. is there. Of course, this invention is applicable also to the support structure of plate materials other than a window glass.
[0008]
The opening of the housing has a square or rectangular shape when viewed from the front, and a frame (not shown) having a shape corresponding to the opening is provided on the inner surface thereof. Between the upper frame portion and the lower frame portion of the frame body along the upper surface and the lower surface of the opening, a stand 1 shown in FIG. The upper end portion and the lower end portion of the stand 1 are respectively supported by the upper frame portion and the lower frame portion of the frame body. A plurality of verticals 1 are provided. Each stand 1 is arranged side by side at predetermined intervals in the left-right direction.
[0009]
As shown in FIGS. 1 and 2, the vertical 1 has a vertical body 11 having a cylindrical shape with a rectangular cross section. A vertical plate portion 12 projecting toward the outdoor O side is formed integrally with the vertical main body 11 at the center in the left-right direction of the side surface facing the outdoor O (see FIG. 4) side of the vertical main body 11. The vertical plate portion 12 extends over the entire length of the vertical body 11.
[0010]
As shown in FIG. 2, mounting members 13 are arranged at predetermined intervals in the vertical direction at the end of the vertical plate 11 on the side of the vertical body 11 that faces the right side. The mounting member 13 has an inverted L shape, a slide plate portion 13a extending vertically along the vertical plate portion 12, and a support plate extending horizontally from the upper end portion of the slide plate portion 13a to the right. Part 13b. The slide plate portion 13a is provided on the vertical plate portion 12 so as not to move in the indoor / outdoor direction and the left / right direction, but to be movable in the vertical direction. A stopper 14 is fixed at a position below the mounting member 13 on the left side surface of the vertical plate portion 12 by fixing means such as a bolt B1. When the lower end surface of the slide plate portion 13 a comes into contact with the stopper 14, the mounting member 13 can no longer move downward. That is, the mounting member 13 can move in the vertical direction only above the stopper 14.
[0011]
On the left side facing the left side of the vertical plate portion 12, a mounting member 13 'is provided. The mounting member 13 ′ is configured in the same manner as the mounting member 13 except that it is bilaterally symmetric with the mounting member 13, and includes a slide plate portion 13 a and a mounting plate portion 13 b. Moreover, like the mounting member 13, the mounting member 13 'is prevented from moving downward by striking against a stopper (not shown) provided on the left side surface of the vertical plate portion 12, and above the stopper. It can only move up and down. The placement member 13 ′ is disposed at the same position as the placement member 13 in the indoor side direction, and is located at the same position in the vertical direction as the placement member 13 when contacting the stopper.
[0012]
Between the vertical plate portions 12 and 12 of the two vertical ones 1 and 1 adjacent to the left and right, a cross member 2 having a longitudinal direction in the left and right direction is horizontally disposed. As shown in FIG. 4, the cross member 2 is formed integrally with the main body 21 having a rectangular cross section, and protrudes forward from a side surface of the main body 21 facing the outdoor O side. And a draining plate portion 23 formed integrally with the support plate portion 22 at the end of the support plate portion 22 on the outdoor O side.
[0013]
The main body portion 21 has a length slightly shorter than the interval between the vertical plate portions 12 and 12 of the vertical walls 1 and 1 adjacent to the left and right. Therefore, a gap is formed between the end surface of the main body 21 and the vertical plate portion 12. A support plate portion 13b of the mounting member 13 provided in the one vertical 1 is inserted into the left end opening of the main body portion 21, and is fixed by a fixing means such as a bolt B2. The support plate portion 13b of the mounting member 13 'provided on the right side adjacent to the one side 1 is inserted into the right end opening of the main body 21 and is fixed by a fixing means such as a bolt B2. It is fixed. In this case, of course, both ends of the main body 21 are fixed to the mounting members 13 and 13 'arranged at the same height. Since both ends of the cross member 2 are connected and fixed to the mounting members 13 and 13 ', they can move in the vertical direction. Therefore, when one of the placement members 13 and 13 ′ moves upward due to the interlayer displacement, the other end portion rotates upward about the one end portion on the placement member 13 or 13 ′ side. The surface of the main body 21 facing the indoor I side is slidably in contact with the surface of the vertical main body 11 facing the outdoor O side.
[0014]
The support plate portion 22 extends horizontally over the entire length of the cross member 2. The upper surface and the lower surface of the support plate part 22 are horizontal surfaces. As shown in FIG.1 and FIG.4, the window glass (plate material) 3 which consists of plate glass is mounted in the edge part of the outdoor side of the upper surface of the support plate part 22 via the sealing member S1. Therefore, the window glass 3 is rotationally displaced together with the horizontal member 2 when the placing members 13 and 13 ′ move relatively in the vertical direction due to the interlayer displacement. The upper end surface of the window glass 3 is in contact with the lower surface of the support plate portion 22 via the sealing material S2. The contact location of the upper end surface of the window glass 3 with respect to the support member 22 is the same as the location where the lower end surface of the window glass 3 is placed on the upper surface of the support plate portion 22 in the indoor / outdoor direction.
[0015]
The draining plate portion 23 is formed over the entire length of the support plate portion 22. However, as shown in FIG.1 and FIG.5, the water draining board part 23 is divided | segmented into plurality by forming the notch part 23a. The notch 23a is disposed so as to face a portion between the two horizontal members 2 and 2 adjacent to each other on the left and right. The length in the left-right direction of the notch 23 a is wider than the interval between the cross members 2 and 2. The upper surface of the draining plate portion 23 is formed as an inclined surface that forms a downward slope toward the outdoor O side in order to allow rainwater that slides down the surface facing the outdoor O side of the window glass 3 toward the outdoor O side. Yes.
[0016]
As shown in FIG. 1, on the outdoor O side from the window glass 3, a plurality of vertical pressing edges 15 whose longitudinal directions are directed in the vertical direction are arranged in a straight line. The vertical pressing edge 15 forms a part of the stand 1 and, as shown in FIGS. 1, 4 and 6, the pressing portion 15a and the pressing portion on the surface of the pressing portion 15a facing the room I side. And a connecting plate portion 15b formed integrally with 15a.
[0017]
As shown in FIGS. 1 and 4 to 6, the presser portion 15 a has a relatively thick plate shape, and its longitudinal direction is directed in the vertical direction and its width direction is directed in the horizontal direction. Has been placed. A drainage hole 15f penetrating from the upper end surface to the lower end surface is formed in the presser portion 15a. The upper end opening of the drain hole 15f is closed by a plug 15c. The lower end opening of the drain hole 15f is opened downward. The presser portion 15a is arranged so that the center portion in the left-right direction substantially coincides with the center portion in the left-right direction of the notch portion 23a. That is, the presser part 15a is arranged so that the center part in the left-right direction is positioned at the approximate center of the two window glasses 3, 3 adjacent to the left and right. Moreover, the width in the left-right direction of the presser portion 15a is set wider than the interval between the two window glasses 3, 3 adjacent to the left and right. Therefore, the left and right side portions of the surface facing the room I side of the presser portion 15a are opposed to the respective side portions in the left and right direction of the surface facing the outdoor O side of the two window glasses 3 and 3 adjacent in the left and right direction. . The presser portion 15a has a length slightly shorter than the pitch in the vertical direction of the two horizontal members 2 adjacent in the vertical direction. As a result, the two presser portions 15 a and 15 a adjacent to each other in the vertical direction are spaced apart from each other in the vertical direction by the length of the presser portion 15 a shorter than the pitch of the cross member 2. As shown in FIG. 4, the gap formed between the two upper and lower presser portions 15a and 15 is closed by the shielding member 16 spanned between the surfaces of the presser portions 15a and 15a facing the room I side. It has been. This prevents wind and rain from entering the room I through the gap between the presser portions 15a and 15a. The presser portion 15a is arranged so that a portion slightly above the lower end edge thereof faces the cross member 2 in the vertical direction. As a result, the lower end portion of the presser portion 15a is opposed to the four window glasses 3 adjacent in the vertical and horizontal directions.
[0018]
As shown in FIG. 1, the connecting plate portion 15 b is disposed at a substantially central portion of the surface of the pressing portion 15 a facing the room I, and extends over the entire length of the pressing portion 15 a. The connecting plate portion 15b is connected to the vertical plate portion 12 so as not to move in the front-rear direction and the left-right direction. Regarding the vertical direction, as will be described later, the vertical plate portion 12 is immovable below a predetermined position but is connected so as to be movable in the vertical direction above the predetermined position.
[0019]
As shown in FIG. 1, a pair of pressing members 17, 17 ′ whose longitudinal direction is directed in the vertical direction are arranged between the surface of the vertical body 11 facing the outdoor O side and the window glass 3. The pair of pressing members 17 and 17 ′ are a part of the stand 1, and are respectively disposed on the right side and the left side with the vertical plate portion 12 therebetween. One pressing member 17 has a U-shaped cross section, and is disposed in a state in which the open portion faces the vertical plate portion 12 side. And it is connected with the vertical board part 12 so that it cannot move to the indoor side direction and the left-right direction but to the up-down direction. The length of the pressing member 17 is slightly shorter than the interval between the horizontal members 2 and 2 adjacent to each other in the vertical direction. As shown in FIGS. 3 and 4, the lower end surface of the pressing member 17 is placed on the upper surface of the main body 21 of the transverse member 2 via the seal member S <b> 3, and the lower end surface of the pressing member 17 and the main body 21. Is sealed with a seal member S3. A space between the upper end surface of the pressing member 17 and the lower surface of the main body 21 is sealed with a seal member S4. Since the other pressing member 17 'is symmetrical with the one pressing member 17, its description is omitted. Of course, seal members S3, S4 are provided between the lower surface of the pressing member 17 'and the upper surface of the main body portion 21 of the cross member 2, and between the upper surface of the pressing member 17' and the lower surface of the main body portion 21 of the cross member 2. Are provided. Seal members S3 and S4 are provided between the upper and lower end surfaces of the pressing members 17 and 17 'and the upper and lower surfaces of the adjacent horizontal members 2 and 2 so that the pressing members 17 and 17' are cross members. 2 and move up and down.
[0020]
As shown in FIGS. 1 and 5, the left and right sides of the surface facing the room I side of the presser portion 15 a, and the left and right sides of the surface facing the outdoor O side of the window glass 3, 3 facing each side, are shown. Seal members S5 are respectively provided between the side portions. The seal member S5 extends from the upper end edge of the vertical pressing edge 15 disposed at the uppermost position to the lower end edge of the vertical pressing edge 15 disposed at the lowermost position, and penetrates the end portion in the left-right direction of the notch portion 23a vertically. ing. The seal member S5 includes a seal member S1 provided between the lower end surface of the window glass 3 and the upper surface of the cross member 2, and a seal member provided between the upper end surface of the window glass 3 and the lower surface of the cross member 2. It is provided integrally with S2. That is, as shown in FIG. 7, when the window glass 3 is viewed from the outdoor side, the seal member S5 intersects with each end of the seal members S1 and S2, and the room I of the seal member S5 is at the intersection. The seal member S5 is integrally formed with the seal members S1 and S2 so that the surface facing the side and the surface facing the outdoor O side of the seal members S1 and S2 are integrally continuous. As a result, the inside of the building existing on the room I side from the window glass 3 is sealed by the seal members S1, S2, S5, and S5. Therefore, rainwater on the outdoor O side from the window glass 3 does not enter the indoor I side unless the sealing members S1, S2, S5, and S5 are deteriorated to deteriorate the sealing performance.
[0021]
As shown in FIGS. 1 and 5, a seal member S <b> 6 is provided between the opposing surfaces of the pressing member 17 and the window glass 3, and a seal member S <b> 7 is provided between the pressing member 17 ′ and the window glass 3. It has been. Moreover, as shown in FIG. 4, between the lower end part of the surface facing the room I side of the window glass 3 and the upper end part of the surface facing the outdoor O side of the main body part 21 of the cross member 2 facing this, The seal member S8 is provided, and between the upper end portion of the surface of the window glass 3 facing the room I side and the lower end portion of the surface facing the outdoor O side of the main body portion 21 of the cross member 2 facing the seal member S8, S9 is provided. As shown in FIG. 8, the upper and lower ends of the seal members S6 and S7 are integrally formed continuously with the left and right ends of the seal members S8 and S9. As a result, since the sealing members S6 to S9 seal the surface of the window glass 3 facing the room I side in an annular shape along the peripheral edge thereof, the sealing members S1, S2, and S5 are temporarily inside due to the deterioration of the sealing members S1, S2, and S5. Even if rainwater enters, the rainwater does not enter the room I through the window glass 3 and the pressing members 17, 17 ′ and / or between the window glass 3 and the cross member 2. The seal members S6 to S9 are integrally formed, but may be formed separately and the end portions may be fixed to each other.
[0022]
Here, when the sealing performance by the seal member S5 is deteriorated and rainwater enters the space between the presser portion 15a and the window glass 3, the rainwater is transmitted through the vertical plate portion 12 and the pressure members 17, 17 ′. There is a risk of entering the room I from between the contact surfaces of the flow and the pressing members 17, 17 ′ and the vertical body 11. Therefore, a seal member S10 is provided between the contact surfaces of the pressing members 17, 17 ′ and the vertical body 11 respectively. In addition, the lower end portion of the seal member S10 is pressed into contact with the end surface of the seal member S3 on the room I side, and the upper end portion of the seal member S10 is pressed into contact with the end surface of the seal member S4 on the chamber I side. This prevents rainwater from entering the room I from between the vertical body 11 and the pressing members 17, 17 ′. Of course, the seal member S10 extends from the upper end to the lower end of the vertical body 11.
[0023]
By adopting the sealing structure as described above, the end portions adjacent to the left and right of the two cross members 2, 2 and the two horizontal members adjacent to the two cross members 2, 2 on the upper side or the lower side. Between the end portions adjacent to the left and right of the materials 2 and 2, the vertical body 11, the pressing members 17 and 17 ′, the window glasses 3 and 3, the vertical pressing edge 15 (pressing portion 15 a), and the sealing members S 1 to S 10. A vertically sealed space M1 extending in the vertical direction is formed (particularly, see FIGS. 1 and 5). The vertical sealed space M1 is sealed with respect to the room I and the room O. As shown in FIG. 4, the lower end portion of the vertical sealed space M <b> 1 is an upper surface of the support plate portion 22 of the cross member 2, a surface facing the outdoor O side positioned above the support plate portion 22 of the cross member 2, and the window glass 3. And the lower lateral sealed space M2 extending in the horizontal direction formed by the seal members S1 and S8. The upper end of the vertical sealed space M1 is the lower surface of the support plate portion 22 of the lateral member 2, and the support plate of the lateral member 2 The surface facing the outdoor O side located below the portion 22 is communicated with the upper lateral sealed space M3 extending in the horizontal direction formed by the window glass 3 and the sealing members S2 and S9. However, the lower lateral sealed space M2 and the upper lateral sealed space M3 are sealed against the room I and the outdoor O. Accordingly, the vertical sealed space M1 communicates with the upper and lower horizontal sealed spaces M2 and M3, but is sealed against the room I and the outdoor O.
[0024]
When the sealing performance of the seal member S1 is deteriorated, rainwater on the outdoor I side may enter the lower lateral sealed space M2 from between the lower end surface of the window glass 3 and the upper surface of the support plate portion 22. The rainwater does not enter the room I from the lower lateral sealed space M2. This also applies to rainwater that has entered the upper sealed space M3.
[0025]
As shown in FIGS. 2, 4, and 6, the vertical plate portion 12 is formed with a notch portion 12 a reaching from the front end surface on the outdoor O side to the vertical body 1. The notch 12a is disposed at a position corresponding to two cross members 2 and 2 adjacent in the left-right direction. The upper end of the notch 12 a is located above the upper end of the cross member 2, and the lower end is located above the lower end of the cross member 2 but below the support plate portion 22. As shown in FIGS. 4 and 6, a notch portion 15 d is formed at the lower end portion of the connecting plate portion 15 b of the vertical pressing edge 15 so as to reach from the tip end surface (surface on the interior I side) to the presser portion 15 a. The length of the cutout portion 15d in the vertical direction is longer than the length of the cutout portion 12a, and the middle portion of the cutout portion 15d in the vertical direction faces the cutout portion 12a. Therefore, the surface (the surface facing downward) that defines the upper end of the notch 15d is located above the notch 12a. The surface that defines the upper end of the notch 15d usually abuts against a screw member B3 that is screwed and fixed to the notch 12a. The position of the vertical pressing edge 15 at this time is the predetermined position described above, and the vertical pressing edge 15 is not movable downward from the predetermined position with respect to the vertical plate portion 12. When the vertical pressing edge 15 is positioned above a predetermined position with respect to the vertical plate portion 12, the vertical pressing edge 15 is movable in the vertical direction. The notch 15d extends to the lower end of the connecting plate 15b.
[0026]
By forming the notches 12a and 15d, the end faces of the lateral members 2 and 2 adjacent to the left and right are opposed to each other via the notches 12a and 15d. As shown in FIG. 3, an end plate 24 is fixed to each facing end surface of each cross member 2 in a watertight state by fixing means such as adhesion and welding. The length of the end plate 24 in the indoor / outdoor direction is set to be equal to the distance from the surface on the indoor I side of the main body 21 to the surface on the outdoor O side of the support plate 22. The upper surface of the end plate 24 is located slightly above the upper surface of the cross member 2 at any location in the indoor / outdoor direction. A portion of the upper surface of the end plate 24 corresponding to the main body portion 21 is formed on an inclined surface having a downward gradient from the indoor I side toward the outdoor O side. A portion of the upper surface of the end plate 24 corresponding to the support plate portion 22 is a horizontal plane. As a result, the upper surface of the end plate 24 has a stepped shape. The upper surface of the end plate 24 may be positioned at the same position as the upper surface of each corresponding part of the cross member 2. The lower surface of the end plate 24 is located on substantially the same plane as the lower surface of the support plate portion 22.
[0027]
A seal member 4 is provided between the end plates 24 and 24. The seal member 4 is filled over the entire gap between the end plates 24 and 24. Thereby, the clearance gap between the end plates 24 and 24, in other words, between the room | chamber I side surface of the main-body part 21 of the horizontal members 2 and 2 adjacent to right and left to the outdoor O side surface of the support plate part 22 is carried out. The formed gap is sealed by the seal member 4. Since the seal member 4 is filled over the entire gap between the end plates 24, 24, the seal member 4 is formed in the same size and shape as the end plate 24 when viewed from the left-right direction. Moreover, the sealing member 4 has sufficient elasticity to allow the movement when the horizontal plates 2, 2 adjacent to the left and right move relatively in the vertical direction. Therefore, the sealing member 4 is not damaged by the vertical movement of the cross members 2 and 2.
[0028]
As shown in FIGS. 1 and 4 to 6, there is a seal member 5 between the pressing portion 15 a of the vertical pressing edge 15 and the opposing surface of the support plate portion 22 that faces the pressing portion 15 a via the notch portion 23 a. Is provided. The width in the indoor / outdoor direction of the seal member 5 is set to be the same as the distance between the opposing surfaces of the support plate portion 22 and the pressing portion 15a, and the length in the left-right direction is the same as the distance between the seal members S5 and S5. Is set to As a result, in the indoor / outdoor direction, the seal member 5 has a surface facing the outdoor O side of the support plate 22, a surface facing the outdoor O side of the window glass 3, and a surface facing the indoor I side of the pressing portion 15 a, respectively. It contacts in the sealed state, and in the left-right direction, it contacts the inner surfaces facing each other of the sealing members S5 and S5 in a sealed state. The upper surface of the seal member 5 is positioned on the same plane as the upper surface of the support plate portion 22.
[0029]
By providing the seal members 4 and 5, the lower end portion of the vertical sealed space M <b> 1 extending above the two horizontal members 2 and 2 adjacent to the left and right is closed. That is, the vertical sealed space M1 is closed by the main body portion 21 and the support plate portion 22, the end plate 24, the seal member 4 and the seal member 5 of the cross member 2 located on the inner side (inner side of the vertical sealed space M1) from the seal member S3. The water receiving part 6 (refer FIG. 1, FIG. 5) is comprised by them. Therefore, if the sealing performance of the seal member S5 is deteriorated and rainwater enters the vertical sealed space M1 from between the presser portion 15a and the window glass 3, the rainwater is a member of any member facing the vertical sealed space M1. It slides down on the inner surface and is received by the water receiving portion 6, and does not go further downward. Further, if the sealing performance of the sealing member S1 deteriorates and rainwater on the outdoor O side enters the lower lateral sealed space M2 from between the upper surface of the support plate portion 22 and the lower surface of the window glass 3, the rainwater is supported. It flows on the upper surface of the plate part 22 and reaches the vertical sealed space M1. In this case, rainwater flowing on the upper surface of the support plate portion 22 flows below the seal members S8 and S6 or the seal members S8 and S7 and reaches the vertical sealed space M1. Further, when the sealing performance of the seal member S2 deteriorates and rainwater on the outdoor O side enters the upper lateral sealed space M3 from between the lower surface of the support plate portion 22 and the upper surface of the window glass 3, the rainwater enters the seal member S9. Or it flows on the inner surface of the cross member 2 facing the upper lateral sealed space M3 and reaches the longitudinal sealed space M1. As described above, even when any of the sealing members S1, S2, S5 facing the outdoor O is deteriorated and the rainwater window glass 3 of the outdoor O enters the indoor I side, the rainwater is longitudinal. It reaches the sealed space M1 and is received by the water receiver 6.
[0030]
The presser part 15a is formed with a communication hole 15e penetrating from the surface facing the room I side to the inner surface. The communication hole 15 e is disposed so that a part thereof faces the upper surface of the seal member 5. Therefore, rainwater that reaches the water receiving portion 6 from the vertical sealed space M1 flows into the drain hole 15f from the seal member 5 through the communication hole 15e. Rainwater that enters the drain hole 15f is discharged to the outside through the lower end opening.
[0031]
According to the support structure of the window glass 3 having the above configuration, both ends of the cross member 2 are placed on the placement members 13 and 13 ′, and the window glass 3 is placed on the cross member 2. Of course, the upper end corner of the window glass 3 can be prevented from being damaged by the interlayer displacement, and the cross member 2 supports the lower end surface of the window glass 3 over its entire length. Therefore, stress is not concentrated on the lower end portion of the window glass 3, and the stress can be applied uniformly over the entire window glass 3.
[0032]
Moreover, in the support structure of this embodiment, the sealing performance of the sealing members S1, S2, S5 facing the outside is deteriorated, and as a result, rainwater in the outdoor O is vertically sealed space M1, and upper and lower lateral sealed spaces M2, M3. Even if it enters, those rainwaters are received by the water receiver 6. And it penetrates into the inside of the press part 15a from the communicating hole 15e, and is discharge | released outside from the lower end opening part of the press part 15a. Here, if the drainage channel by the inside of the water receiving part 6, the communicating hole 15a, and the presser part 15a is not formed, all the rainwater which invaded passes through the vertical 1 to the lowest layer of the building. Since it flows, a large amount of water accumulates in the lowermost layer, which may enter the room. In this respect, in this embodiment, since the water receiving portion 6 is provided between the horizontal members 2, 2 adjacent to the left and right, the rainwater that has entered the indoor I side from the window glass 3 is received by the water flowing portion 6. It is discharged to the outside and does not flow to the lowest layer of the building. Therefore, it is possible to reliably prevent rainwater from entering the room I in the lowermost layer.
