Description

【0001】
【発明の属する技術分野】
本発明は、建築構造物の壁面を構成する外装板、特にガラス板の支持装置に関する。
【0002】
【従来の技術】
建築物の外壁として、ガラス板をはじめとして外装板だけで構成するデザインが普及しつつある。この種の外装板、特にガラス板の支持装置の先願技術としては、特開平8−144408号公報、特開平8−170390号公報に開示されている。
上記両開示技術とも、ガラス板からなる建物外壁の支持構造に係るものであるが、これらのいずれもが重量物である多数のガラス板を室内側から室外側に突出する水平部材により支持させるものであることから、水平部材として構造的に耐荷重性の大きなものを使用する必要があった。
【0003】
このような構造物は、ガラス板のみの壁面であることから外観の意匠性は優れているが、室内側には支持力のおおきな支持構造体を必要とし、支持構造体としての建築素材を多く必要とするばかりでなく、構造力学上の観点から設計の自由度が限定されてしまい、意匠的に外観ほど好ましいデザインが実現できなかった。
【0004】
【発明が解決しようとする課題】
本発明は、上記従来技術の不具合を解決すべく発明されたものであって、外装板の支持を吊り構造とすることにより、室内側の支持構造体をスリム化し設計上の自由度を向上させることを課題とするものである。
【0005】
【課題を解決するための手段】
上記課題を解決するために、
本発明の請求項1記載の建築構造物の外装板支持装置は、構造物の躯体から吊り棒を垂下し、該吊り棒に設けた外装板保持枠を介して複数の外装板を略同一鉛直面内に保持させると共に、室内に設けたワイヤ構造体に対して前記外装板保持枠の室内側を相対姿勢変更可能に連結すると共に、吊り棒を外装板間で前記同一鉛直面内に位置させることにより、外装板の荷重支持を主として吊り棒により行なわせ、ワイヤ構造体には主として外装板の室内外方向の移動を規制させ、特に、吊り棒を外装板の面内に位置させたことから、外装板の略全重量を吊り棒で支持吊させることを特徴とする。
【0006】
本発明の請求項2記載の建築構造物の外装板支持装置は、請求項1記載の手段に加えて、ワイヤ構造体に外装板保持枠を連結するに当たって、伸縮可能な水平支持体を介在させ、且つ外装板保持枠と水平支持体とをユニバーサルジョイントで連結することにより、水平支持体を伸縮して外装板保持枠の面外方向(室内外方向)の位置調整を行い、且つ、ユニバーサルジョイントで外装板保持枠の上下左右方向の移動が可能な状態で連結することを特徴とする。
【0007】
本発明の請求項3記載の建築構造物の外装板支持装置は、請求項1又は2記載の手段において、外装板間毎に設けた複数の外装板保持枠にそれぞれ水平支持体を設け、横に隣接する水平支持体同士を横繋ぎ長尺体で連結することにより、水平支持体同士の個々の水平動を規制することを特徴とする。
【0008】
本発明の請求項4記載の建築構造物の外装板支持装置は、請求項3記載の手段において、ワイヤ構造体は、それぞれの端部を躯体上下に取り付けて交差して配置する2本のワイヤと、両ワイヤの間隔を保持させる間隔保持体とから構成し、間隔保持体の室外側端部に水平支持体を連結したことにより、ワイヤ構造体を柔構造として、水平支持体を上下移動可能な状態で支持させることを特徴とする。
【0009】
【発明の実施の態様】
本発明の実施例を図面を参照して説明する。
(構造物の躯体)
本実施例を適用する構造物は、図2〜4に示すように、外装板として大型のガラス板1を用いる構造物で、一般のビルの他、公共施設のホールやプール等に適している。構造物の躯体2はこれらの骨格となるもので主として鉄筋コンクリート等で構築する。
外壁を構築する部分の上方の躯体2には吊り棒3上端の吊下げ部4を、また、下方には吊り棒3下端の止め部5を設ける。前記吊下げ部4及び止め部5の室内側には、図5に示すように、ワイヤ10、11の取付金具7・・・を設ける共に、図9に示すように支柱8・・等の取付部6・・を設ける。
【0010】
(外装板1)
外装板として用いるガラス板1・・は、建物の種類に応じて種々の大きさのものを用いるが、四方形状の強化ガラスとフロートガラスとの合わせガラスが一般的である。その他、例えばフロートガラスとフロートガラスとの合わせガラスや飛散防止フィルムを積層したフロートガラスを使用してもよい。
ガラス板1は全体としては方形状であるが、その各コーナー部は後述の支持装置で支持させるため僅かにカットしてある。ガラス板1のコーナー部のカットは、地震時に楔、座金、ナット、高ナット等とガラス板が接触しない状態で安定的に支持させるために行うものである。
【0011】
ガラス板1は、上記カット以外には格別の加工を施す必要はない。しかし、加工を施すことを妨げるものではない。例えば、後述の吊り棒3・・の存在を室外から見えないようにするために、ガラス板1の縦辺にその長さ方向に沿って水平断面半円の凹部を設け、この凹部に吊り棒3を配置してもよい。また、ガラス板1は着色したり、補強ネットを内挿させてもよい。
【0012】
(吊り棒3)
吊り棒3は、図1(ロ)及び図6に示すように、PC鋼を素材とし断面円形で長尺の鋼棒を用いるが、多数の細い鋼線を編んだ可撓性のもので構成してもよい。その上下端は、図4に示すように、躯体2の取付部に装着する。
また、吊り棒3の太さ(水平断面積)は支持するガラス板1・・の総重量により引張応力が変わってくるから、その負荷に応じて適宜設計する。吊り棒3はガラス板1・・の横方向の隙間毎に設ける。また、基本的には吊り棒3はすべて同一構成である。
【0013】
(ワイヤ構造体9)
ワイヤ構造体9は躯体2における吊り棒3の吊下げ位置より室内側に設け、図3〜7のいずれかに示すように、全体として躯体2の上下に取り付けるワイヤ10、11及び間隔保持体14からなる。
ワイヤ10、11は2本一組で並設し、その上下端を躯体2に設けたワイヤ取付金具7に固着する。また、前記両ワイヤ10、11間には水平状態に間隔保持体14・・を装着し、これらワイヤ10、11及び間隔保持体14・・からなるワイヤ構造体9をガラス板1・・の面に沿って複数併置し、全体としてワイヤ構造体9・・・をトラス状に形成する。
【0014】
各間隔保持体14・・・の室外側端部には、それぞれ水平軸15・・を設け、該水平軸15・・には後述の水平支持体16・・の内側連結ボルト17・・を軸着する。
なお、本実施例は、上記のように躯体に取り付けられているワイヤ10、11及び間隔保持体14を用いているが、この構造はあくまでも一実施例であり、本発明のワイヤ構造体9としては、例えば鋼管、吊り棒、又は、鋼杆等からなるトラス構造等を用いてもかまわない。また、ワイヤは2本に限らず3本でも良く、柱を付加的に用いても良い。いずれにしても種々のトラス構造が考えられる。
ワイヤ構造体9は、ワイヤ10、11及び間隔保持体14を用いることにより、後述の水平支持体16を僅かに、即ち、ワイヤ10、11の伸びの範囲で水平支持体16を揺動可とすることができ、地震等でガラス板1が揺動するとき追従させることができる。
【0015】
(水平支持体16)
水平支持体16は、図1及び図6、7に示すように、ワイヤ構造体9に対して外装板保持枠18を繋ぐ部材であり、ワイヤ構造体9に対する外装板保持枠18の室内外方向の距離を変更可能とするものである。
【0016】
水平支持体16は、間隔保持体14・・の室外側端部に設けた上記水平軸15・・に、上下方向に揺動自在に軸着された内側連結ボルト17と、この内側連結ボルト17に螺合する距離調整パイプ17aと、該距離調整パイプ17aの室外側で螺合する外側連結ボルト20bと、該外側連結ボルト20bの他端部に設けた支持ベアリング28とから構成する。
【0017】
そして、該支持ベアリング28を嵌合させるベアリング受け27は、後述の外装板保持枠18の受けフランジ24に係合する。
水平支持体16を、上記のように構成することにより、外装板保持枠18を水平方向の移動は不可で上下方向の移動は可となるように支持している。また、距離調整パイプ17aの回動により、室内外方向に外装板保持枠18の位置を調整して支持させる。外装板保持枠18の位置の調整は、ガラス板1・・・の設置時あるいは設置後においても適宜行うことが可能である。
【0018】
水平支持体16には、図1(ロ)、図8に示すように、水平支持体16の長さ方向とは直角に横繋ぎ長尺体20を連結するためのジョイント20aを付設する。
【0019】
(横繋ぎ長尺体20)
隣接する上記ジョイント20a同士は、図8に示すように、横繋ぎ長尺体20で連結する。この構成により、左右に隣接する水平支持体16、16同士の個々の水平移動が規制される。
なお、横繋ぎ長尺体20の設置は本実施例の必須の構成要件ではないが、ガラス板1・・の水平支持体16による安定的な支持のために設置することが好ましい。
【0020】
(外装板保持枠18)
吊り棒3には、図2及び図3に示すように、ガラス板1・・の上下の長さ毎に、外装板保持枠18・・を設ける。各外装板保持枠18は、室内側保持板21、外装板受け体22及び室外側保持板23から構成される。
【0021】
(室内側保持板21について)
室内側保持板21は、図1(イ)(ロ)に示すように、その室内側に設けた水平支持体16に連結する受けフランジ24と、室外側に配置する外装板受け体22と、後述の室外側保持板23を保持する連結孔25と、吊り棒3と係合する係合部26とを備え、隣接配置した4枚のガラス板1・・・のコーナー部に配置する。
【0022】
室内側保持板21は、剛性の高い金属素材を用いて薄い円盤状に形成し、その室内側の面には、円管状の受けフランジ24を一体に形成し、該受けフランジ24には前述のベアリング受け27を係合する。なお、室内側保持板21は必ずしも円盤状である必要はなく略方形状以外の他の形状であってもよい。
また、本実施例では、水平支持体16の室外側端部と室内側保持板21とを三次元的に回動自在に連結する手段として、支持ベアリング28及びベアリング受け27からなるユニバーサルジョイント29を構成させるが、他の手段、例えば複合ヒンジ等を採用しても良い。
【0023】
(外装板受け体22について)
室内側保持板21の室外側の面には、上下の中間位置に水平状で直角に突出する外装板受け体22を一体的に形成する。
該外装板受け体22は、その上部にガラス板1、1の重量を受けることから、剛性の高い素材で上下の二重板より構成すると共に平面視長方形状に形成し、その中央部、即ち、室内側保持板21の中心位置近傍の係合部26に後述の吊り棒3を上下に挿通させるための切欠き30を形成する。
【0024】
上記外装板受け体の室外側の面には、図11(イ)(ロ)(ハ)に示すように、左右に室外支持板を装着するための連結孔25、25を穿設する。更に、外装板受け体22の切欠き30の両側の水平部の上面には、外装板受け体22と一体に板状の樹脂材からなるガラスライナ32、32を設け、また、同外装板受け体22の下面には、外装板受け体22と一体に板状のシリコンゴムからなるガラス当接片33、33を設ける。
【0025】
更に、室内側保持板21の室外側の面には、左右前後のガラス板1・・・の側面に対応する位置にガラス押え支持部34・・・を設ける。該ガラス押え支持部34・・・には、支持させるガラス板1の中心に向かう方向に凹凸溝を形成し、このガラス押え支持部34・・・に、四枚の楔状のガラス押え35・・・を張り付けて配置する。ガラス押え35・・・はゴムを素材としている。
また、上記ガラス押え35・・のガラス板1・・の当接面においても、支持させるガラス板1・・の中心に向かう方向に凹凸溝を形成してもよい。このような方向に凹凸溝を形成したことにより、ガラス板1は凹凸溝稜線で支持することになり、ガラス板1に曲げ応力が発生しない。
【0026】
(室外側保持板23について)
室外側保持板23は、図1に示すように、その室内側の面の左右前後のガラス板1の側面に対応する位置にガラス押え支持部36を凹凸状に形成し、このガラス押え支持部36・・・に、四枚の楔状のガラス押え37・・・を張り付ける。ガラス押え37・・・はゴムを素材としている。したがって、室外側保持板23及びガラス押え37・・・の構成及び素材は基本的には室内側保持板21及びガラス押え35と同じである。室外側保持板23は、室内側保持板21にビスにより連結する。
【0027】
(吊り棒3への装着部について)
吊り棒3には、上下に一定間隔、即ちガラス板1の上下幅毎に取付パイプ38を取り付ける。各取付パイプ38・・・には、吊り棒3の外周に吊り棒3と一体に楔39を用いて取り付けるが、外周には図10に示すように雄ネジ40を刻設してある。
このとき、楔39は取付パイプ38の下部と吊り棒3の外周との隙間に食い込んで、吊り棒3と噛み合い状態となるため、取付パイプ38にガラス板1・・・の荷重がかかっても、取付パイプ38は吊り棒3に確実に係止され、ずり落ちるようなことはない。
【0028】
各取付パイプ38には、図10に示すように、その下方に上下幅の大きい高ナット41と、その上方に通常長さのナット42を螺合して上下位置を設定自在に配置する。
また、高ナット41を用いた理由は、後述するようにこの高ナット41にガラス板1・・の荷重がかかることから、対応力を増大させるためである。
【0029】
上記取付パイプ38に、平面形状U型で金属弾性を有する上下の座金43、43を介して上記外装板受け体22の係合部26を挟持させ、両ナット41、42を締付けることによって吊り棒3に支持させる。そして、上方の座金43の上面は二等辺形状の山形に形成し、且つ下方の座金43の下面は二等辺形状の逆山形に形成し、これらの山形部にナット42の下面及び高ナット41の上面がそれぞれ滑動可能に当接している。
換言すれば、ガラス板受け体22は上下の座金43、43を介して取付パイプ38に鉛直面内において揺動可能に支持されていることになる。
【0030】
(ガラス板1の取り付け)
本実施例において、躯体2及びワイヤ構造体9にガラス板1・・を取付けるには、次の順序に従って行う。
【0031】
第一段階(ワイヤ構造体9の取付け)
先ず、ワイヤ構造体9を構成するワイヤ10、11の上下端を取付金具7により躯体2に取付ける。そして両ワイヤ10、11間に間隔保持体14・・を介在させワイヤ10、11を緊張状態にする。なお、10a、11aはそれぞれワイヤ10、11の緊張具である。
【0032】
第二段階(吊り棒3の取付け)
躯体2に吊り棒3・・の上下を取付ける。なお、吊り棒3・・には、係合部26を構成する一定間隔(ガラス板1の上下長さ)に設けた高ナット41及びナット42を予め螺合した取付パイプ38に楔39を用いて取付け・固定しておく。
【0033】
第三段階(水平支持体16の取付け)
ワイヤ構造体9の間隔保持体14の示す水平軸15(図1参照)に、水平支持体16を軸着する。
第四段階(室内側保持板21の取付け)
図1又は図10に示すように、吊り棒3に設けた取付パイプ38に係合部26の切欠き30を係合し、上下に座金43、43を介装し、高ナット41及びナット42により上下から挟持して締め付け、室内側保持板21を装着する。
併せて、図1に示すように水平支持体16と支持ベアリング28、ベアリング受け27を連結する。
【0034】
第五段階(ガラス板1の取付け)
最下部のガラス板1・・を吊り棒3、3間に装着し、室外側保持板23を室内側保持板21に装着して上記ガラス板1の両コーナーを係合する。最下部一段目のガラス板1の装着が終った後、下から二段目のガラス板1・・の装着を行う。
第六段階(室外側保持板23の取付け)
そして順次上方に向けてガラス板1・・を装着していく。該装着毎に室外側保持板23をビスにより室内側保持板21に固定していく。ガラス板1の取付け後の状態は図1〜3のとおりである。
【0035】
(実施例の作用効果)
本実施例は上記構成により、外装板1の支持をワイヤ構造体9と吊り棒3とにより行い、特にガラス板1の荷重の支持を主として吊り棒3により行う構成であるから、荷重の支持に無理がなく効率的である。
また、ワイヤ構造体9は、主としてガラス板1の室内外方向及び水平方向の移動を一定範囲内に規制するのみであるから、その必要耐応力を大幅に小さくすることができる。
【0036】
特に、本実施例では、水平支持体16と外装板保持枠18とを三次元的に回動自在に連結する手段として、支持ベアリング28及びベアリング受け27を介装したユニバーサルジョイント29としたこと、及び、取付パイプ38・・の上方に位置させる座金43の上面は山形に形成し、下方に位置させる座金43下面は逆山形に形成して、これらの山形部にナット42の下面及び高ナット41の上面を滑動可能に当接させることにより、外装板受け体22を上下の座金43、43を介して取付パイプ38に揺動可能に支持させる。
【0037】
よって、吊り棒3に対して外装板受け体22が回動可能に支持することになるから、吊り棒3とガラス板1との隙間が少なくてもガラス板1の移動に対応して安全に追従させせることができ、地震等による振動にも十分耐えることが可能である。
また、部分的にガラス板1が損傷することがあっても、損傷したガラス板1の上方左右コーナー部の室外側保持板23を取外し、かつ下方左右コーナー部の室外側保持板を緩めることで交換できる。依ってガラス板1のメンテナンスも容易である。
なお、上記実施例では、ガラス板1として通常のガラス板1を用いる場合の説明したが、前記の強化ガラス板を使用する場合にも本発明は適用することができ、更には、ガラス板ではなく、アルミ合金、スチール板、ステンレス板等の金属パネル、石材等の外装板にも適用できることはいうまでもない。
【0038】
【発明の効果】
本発明は、上記構成により下記の効果を奏する。
1.請求項1記載の発明によれば、外装板の荷重の支持を主として吊り棒により行なわせ、ワイヤ構造体は主として外装板の室内外方向及び水平方向の移動を規制し、特に、吊り棒が外装板の面内にあることから外装板の略全重量を吊り棒で支持吊することになり、支持装置において吊り棒に引張り力のみを作用させることで、荷重の支持に無理がなく効率的である。また、ワイヤ構造体は主として外装板の室内外方向及び水平方向の移動を規制するのみであるから、ワイヤ構造体の必要耐応力を大幅に小さくすることができる。
特に、吊り棒が外装板の面内にあることから、外壁を支持する構造材がシンプルになり意匠上の効果が期待できる。
【0039】
2.請求項2記載の発明によれば、上記効果に加えて、水平支持体を伸縮して外装板保持枠の面外方向(室内外方向)の位置調整を行い、且つ、ユニバーサルジョイントで外装板保持枠の上下左右方向のある程度の移動を許容する状態で連結するから、外装板の取付及び保守が容易である。
【0040】
3.請求項3記載の発明によれば、請求項1又は2記載の効果に加えて、水平支持体同士の個々の水平動を規制することで、地震時等で外装板が揺動したとき、全体として、整合性がとれた形状に保持することができる。
【0041】
4.本発明の請求項4記載の発明によれば、請求項3記載の効果に加えて、ワイヤ構造体を柔構造として、水平支持体のある程度の上下移動を許容しながら支持させることで、ワイヤ構造体への荷重を少なくし、室内側に過大な構造物を設ける必要をなくした。
