Description

【０００１】
【発明の属する技術分野】
本発明は、例えば、ガラスカーテンウォールのように、構造躯体（構造体の一例）に対して取付金具（取付具の一例）でガラスパネル（壁体パネルの一例）を取り付けるような場合の壁体パネル支持構造に関し、更に詳しくは、構造体に、取付具を介して壁体パネルを取付自在な第一取付部を設け、前記第一取付部に対して取付自在な第二取付部と、前記壁体パネルに取付自在な第三取付部とを、前記取付具に設け、前記第二取付部を前記第一取付部に取り付けると共に、前記第三取付部を前記壁体パネルに取り付けることで、前記壁体パネルを前記構造体に支持させてある壁体パネル支持構造に関する。
【０００２】
【従来の技術】
従来、この種の壁体パネル支持構造としては、図２３に示すように、前記第一取付部２を横棒形状の棒状部２ａで構成すると共に、取付具１の第二取付部１Ａは、第一取付部２を受け入れ自在な横方向のアリ溝３０を備えた外嵌部３１で構成し、前記アリ溝３０は、その開口３０ａが下を向く状態に形成すると共に、アリ溝３０内の両側壁３０ｂを、溝端部側ほど対向距離が大きくなるテーパー面に形成して、前記棒状部２ａと前記外嵌部３１とが、前記第一取付部２の長手方向に沿って相対移動自在に、且つ、互いの軸芯周りに相対回転自在に、且つ、前記棒状部２ａの一端部が壁体パネル厚み方向に沿って近接離間する状態に相対揺動自在に嵌合させてあるものがあった（例えば、特開平７−２０７７９０号公報参照）。
また、この壁体パネル支持構造においては、前記第一取付部２に対して取付具１を取り付ける際の利便性を考慮して、アリ溝３０開口の片側部分は、着脱できる着脱ブロック３２で構成してあり、アリ溝３０内に前記第一取付部２を嵌入させた後、前記着脱ブロック３２を取付具１本体にネジ止めすることで第一取付部２への取付具１の取り付けを完了するものであった。
【０００３】
【発明が解決しようとする課題】
壁体パネルは、ある範囲内で構造体との相対移動をできる状態に取り付けておくことで、地震や強風の発生時の応力が壁体パネルの取付部に集中するのを緩和できることは既に知られているが、上述した従来の壁体パネル支持構造によれば、前記棒状部２ａと前記外嵌部３１とが、前記第一取付部２の長手方向に沿って相対移動自在に、且つ、互いの軸芯周りに相対回転自在に、且つ、前記棒状部の一端部が壁体パネル厚み方向に沿って近接離間する状態に相対揺動自在に嵌合してあるから、それらの方向に相対移動することができるものの、壁体パネルが壁面に沿って揺動する動きに関しては緩和することが困難である。第一取付部と第二取付部間にこのような動きが生じるのは、地震の横揺れが生じた場合であり、この動きを緩和できなければ、壁体パネルの取付箇所に応力集中が発生し易く、その結果、壁体パネルや取付具が破壊したり、外れて落下したりするといった問題点がある。
【０００４】
従って、本発明の目的は、上記問題点を解消し、地震や強風が発生しても、壁体パネルの取付部に応力集中の発生し難く、且つ、安定した状態に壁体パネルを支持可能な壁体パネル支持構造を提供するところにある。
【０００５】
【課題を解決するための手段】
請求項１の発明の特徴構成は、図４〜２２に例示するごとく、構造体Ａに、取付具１を介して壁体パネルＰを取付自在な第一取付部２を設け、前記第一取付部２に対して取付自在な第二取付部１Ａと、前記壁体パネルＰに取付自在な第三取付部１Ｂとを、前記取付具１に設け、前記第二取付部１Ａを前記第一取付部２に取り付けると共に、前記第三取付部１Ｂを前記壁体パネルＰに取り付けることで、前記壁体パネルＰを前記構造体Ａに支持させてある壁体パネル支持構造において、前記第一取付部２と前記第二取付部１Ａとの一方は、前記第一取付部２と前記第二取付部１Ａとの他方を受け入れ自在な横方向のアリ溝６を備えた外嵌部３ｂで構成し、前記第一取付部２と前記第二取付部１Ａとの他方は、壁体面に沿う方向に横長で前記アリ溝６に内嵌自在な棒状部２ａと、前記アリ溝６の開口６ａを通して前記棒状部２ａと一体連結する繋ぎ部２ｂとを備えて構成し、前記棒状部２ａと前記外嵌部３ｂとは、前記棒状部２ａの長手方向に沿って相対移動自在に、且つ、互いの軸芯周りに相対回転自在に、且つ、壁面に沿って相対揺動自在に、且つ、前記棒状部２ａの一端部が壁体パネル厚み方向に沿って近接離間する状態に相対揺動自在に嵌合させてあり、その嵌合状態での前記外嵌部３ｂは、前記アリ溝６の開口６ａが前記壁面に対する近接離間方向の何れかに向く状態に設置してあるところにある。
請求項１の発明の特徴構成によれば、前記第一取付部と前記第二取付部とを、一方は、横配置のアリ溝を備えた外嵌部で、他方は、横長の前記棒状部、及び、前記繋ぎ部とを備えて構成し、前記棒状部と前記外嵌部とは、前記棒状部の長手方向に沿って相対移動自在に、且つ、互いの軸芯周りに相対回転自在に、且つ、壁面に沿って相対揺動自在に、且つ、前記棒状部の一端部が壁体パネル厚み方向に沿って近接離間する状態に相対揺動自在に嵌合させてあるから、例えば、鉛直面に沿うように支持された状態の壁体パネルは、壁面に沿って左右にスライドできたり、連結点を中心として壁面が斜め上方や斜め下方に向く状態に揺動できたり、壁面に対する正面視において、連結点を中心に右回りや左回りに揺動できたり、連結点を含む縦軸芯周りに揺動することが可能となる。勿論、壁体パネルの初期取付状態が鉛直面から傾斜している場合については、その初期状態を基準にして同様の動きを期待することができる。
従って、壁体パネルの支持状態を維持しながら、より多方向への動きを許容できるようになり、構造体と壁体パネルとの取付箇所に応力集中が起こり難くでき、例えば、地震や強風の発生時にも、壁体パネルを無理なく支持することが可能となる。その結果、壁体パネルの支持状態が単純支持化され、壁体パネル内に生じる応力をも緩和することが可能となるから、地震や強風が発生しても、安定した状態に壁体パネルを支持することが可能となる。更には、前記第一取付部や、第二取付部・第三取付部の設置位置が、現場状況によって多少位置ずれするような場合であっても、その位置ずれを、前記棒状部と外嵌部との相対的な移動や回転や揺動等によって吸収することが可能となるから、壁体パネルの取付作業に手間が掛からず、無理なく迅速に進めることが可能となる。
また、棒状部との嵌合状態における前記外嵌部が、前記アリ溝の開口が前記壁面に対する近接離間方向の何れかに向く状態に設置してあるから、外嵌部そのものは、アリ溝開口以外の部分が連続部材として応力負担することができ、外嵌部と棒状部との間に作用する力を、前記連続部材部分で受けることが可能となる。
特に、構造体から前記壁体パネルを引き外す方向の力が作用した場合、前記棒状部とアリ溝の開口裏側部分とが当接することで受け止められるが、外嵌部内の応力状況としては、棒状部の両側方に位置する前記連続部材（アリ溝両側壁）部分で均等に受けることが可能となる。従って、従来のもの（アリ溝開口が下方向に向けてあり、前記応力が外嵌部のアリ溝底部の少ない部材断面内でのみ負担するもの）に比べて、壁体パネルへの引き外し力の作用に対する耐力が増加し、より強力な壁体パネル支持力を発揮することが可能となったり、従来と同様の支持力を期待する場合には、外嵌部の部材断面を小さくして、壁体パネルの固定部分のコンパクト化を図ることが可能となる。
更には、外嵌部に上述の通り開口方向を設定した状態にアリ溝を設けてあることによって、アリ溝内に前記棒状部を嵌合させた状態でそのアリ溝の開口に前記繋ぎ部を位置させることができるから、棒状部と繋ぎ部との連結構造を、例えば、棒状部の中央部に繋ぎ部を設けるものとしたり、棒状部の両端部に繋ぎ部を設けるものにしたり、又は、棒状部の一端部に繋ぎ部を設けるものにしたり、又は、棒状部全長にわたって繋ぎ部を設けるものにしたりと言うように、何れの構成をとっても、外嵌部と棒状部との相対移動を許容することができる。よって、前記繋ぎ部の配置や姿勢等の設計の自由性が向上すると共に、美観性の向上をも図ることも可能となる。そして、アリ溝の開口方向が前記壁面に対する近接離間方向の何れかに向く状態に設置してあるから、従来のものに比べて繋ぎ部そのものの部材長をより短くして、応力的に有利な状態とすることが可能となる。
【０００６】
請求項２の発明の特徴構成は、図１に例示するごとく、前記第三取付部１Ｂは、隣接する壁体パネルＰどうしの縦目地を貫通して両壁体パネルＰ縁部を挟持する状態に形成してあるところにある。
請求項２の発明の特徴構成によれば、請求項１の発明による作用効果を叶えることができるのに加えて、第三取付部を壁体パネルに貫通させて取り付ける場合に比べて、壁体パネルの強度低下の少ない状態で支持することが可能となる。その結果、より大きな外力（壁体パネルに作用する外力）にも耐えることが可能となる。
【０００７】
請求項３の発明の特徴構成は、図４〜１１に例示するごとく、前記棒状部２ａは、円柱形状であり、前記アリ溝６は、両端部ほど大径になるように内周面をラッパ形状に形成してあるところにある。
請求項３の発明の特徴構成によれば、請求項１又は２の発明による作用効果を叶えることができるのに加えて、棒状部とアリ溝内周部との接当面積を小さくして、相互のスライド移動時の摩擦抵抗力の低減化を図ることができ、スムースな相対スライドが可能となる。更には、棒状部と外嵌部との相対揺動時に、相互の接当部分が徐々に移動しやすく、スムースな揺動を許容することが可能であると共に、接当部分が常に同じであるのに比べて、局部の摩耗を減少させることが可能となり、部品の耐久性を向上させることができる。
【０００８】
請求項４の発明の特徴構成は、図５に例示するごとく、前記棒状部２ａは、その長さを前記アリ溝６の長さより大きく設定してあると共に、その中央部に前記繋ぎ部２ｂを設けてあるところにある。
請求項４の発明の特徴構成によれば、請求項１〜３の何れかの発明による作用効果を叶えることができるのに加えて、棒状部と外嵌部とが相対スライドする場合に、両者の嵌合が外れ難く、且つ、繋ぎ部に複雑な曲げモーメントが作用し難く、安定した状態に壁体パネルを支持することが可能となる。
【０００９】
尚、上述のように、図面との対照を便利にするために符号を記したが、該記入により本発明は添付図面の構成に限定されるものではない。
【００１０】
【発明の実施の形態】
以下に本発明の実施の形態を図面に基づいて説明する。尚、図面において従来例と同一の符号で表示した部分は、同一又は相当の部分を示している。
【００１１】
図１は、本発明の壁体パネル支持構造の一例として、取付具１を使用して、複数のガラスパネル（壁体パネルの一例）Ｐを構造体Ａに取り付けてある状況を示すものである。
【００１２】
前記ガラスパネルＰは、矩形形状に形成してあり、それぞれ目地２０をあけて並設することで壁体を構成している。尚、ガラスパネルＰは、図に示すように、上縁部と下縁部とを、支持枠体Ａ１・Ａ２に嵌合させてあり、ガラスパネルＰの重量の大半は、セッティングブロックＳを介して下側の支持枠体Ａ２に支持させてある。そして、地震等の横揺れによって両支持枠体Ａ１・Ａ２どうしが横にずれるような挙動を示す場合には、図７に示すように、ガラスパネルＰがガラス面に沿って揺動できるように、各支持枠体Ａ１・Ａ２内には、揺動隙間Ｙを確保した状態に嵌合させてある。そして、ガラスパネルＰの上下中間部分の複数箇所においては、前記取付具１によって目地縁部を挟持支持することによって、ガラスパネルＰの厚み方向への移動阻止を図ってある。
また、隣接するガラスパネルＰ間の目地２０には、前記取付具１の他、全長にわたって弾性目地材Ｍ１が充填してあり、目地の閉塞と共に防水を図ってある。
更には、ガラスパネルＰ上下縁部と、前記上下の支持枠体Ａ１・Ａ２との間には、弾性シール材Ｍ２を充填してある。
【００１３】
前記構造体Ａは、図２に示すように、上下階の各スラブＡ３の外縁部に、前記支持枠体Ａ１・Ａ２を各別に設けてあると共に、前記ガラスパネルＰどうしの目地位置に対応する位置に、上下階のスラブＡ３にわたる金属製の構造フレームＡ４を設けてある。
そして、この構造フレームＡ４の中間部には、前記取付具１を取り付けるための第一取付部２を設けてある。この第一取付部２について説明すると、図３〜５に示すように、断面円形で壁面に沿った横長の棒状部２ａと、前記棒状部２ａを構造フレームＡ４からガラスパネルＰ側へ突出した状態に支持する繋ぎ部２ｂとを金属で一体的に設けて構成してある。
前記棒状部２ａは、その長さ寸法は、前記取付具１の幅の数倍程度に設定してあり、その中央部に前記繋ぎ部２ｂが設けてある。
前記繋ぎ部２ｂは、水平平板部分と、鉛直平板部分とで構成してあり、鉛直平板部分を、前記構造フレームＡ４にボルト固定してある。また、水平平板部分の厚み寸法は、前記棒状部２ａの外径寸法より小さく設定してある。
【００１４】
前記取付具１は、図３〜５に示すように、取付具本体３と、その取付具本体３に対して前記ガラスパネルＰを挟持する状態に着脱自在な挟持用円盤部材４とを備えて構成してある。
そして、図に示すように、取付具本体３を前記第一取付部２に取り付けると共に、取付具本体３と円盤部材４とによって隣接する一対のガラスパネルＰ縁部を挟持することによって、ガラスパネルＰを構造フレームＡ４に支持させることができるものである。
前記円盤部材４は、金属で形成してあり、その外径寸法を前記目地２０の幅寸法より大きく、具体的には、数倍程度になるように形成してある。また、裏面（前記取付具本体３側を向く面）には、前記目地２０を貫通させて前記取付具本体３と連結自在な複数のボルト部４ａが一体的に設けてある。
また、前記取付具本体３は、『ハット』形状の金属部材で構成してあり、ハットの鍔部分３ａが、前記円盤部材４に対向すると共に、ハットの胴部分（外嵌部の一例）３ｂが、前記構造フレームＡ４側に向く姿勢に設置される。前記円盤部材４と鍔部分３ａとでガラスパネルＰを挟持支持することができ、この両者で、第三取付部１Ｂが構成されている。
前記鍔部分３ａは、前記円盤部材４とほぼ同様の円盤形状に形成してあり、そこには、前記ボルト部４ａが各別に挿通自在なボルト挿通孔５を複数設けてある。
そして、前記円盤部材４、及び、前記鍔部分３ａの対向面には、ゴムシートＧをそれぞれ貼着してあり、挟持したガラスパネルＰとのメタルタッチを防止すると共に緩衝効果を期待できるように構成してある。因みに、ガラスパネルＰの挟持は、前記鍔部分３ａと円盤部材４との間に左右のガラスパネルＰ縁部を位置させた状態で、目地２０を貫通させたボルト部４ａを前記ボルト挿通孔５に挿通させてナットＮを螺合させて締め付けることによって実施される。
前記胴部分３ｂには、前記構造フレームＡ４側に開口６ａが向くアリ溝６を、長手方向が横になるように設けてある。そして、前記開口６ａの開口幅寸法は、前記棒状部２ａの外径寸法より小さく、且つ、前記繋ぎ部２ｂの水平平板部分の厚み寸法より大きくして、前記棒状部２ａと前記外嵌部３ｂとが、互いの軸芯周りに相対回転できるように設定してある。
また、アリ溝６は、断面形状が円形となるように構成してあり、アリ溝内周面６ｂは、両端部ほど大径になるように内周面をラッパ形状に形成してある。そして、アリ溝６中央部の最小径の部分でのアリ溝内径寸法は、前記棒状部２ａより少し大きめの値に設定してある。従って、前記棒状部２ａの一端部にアリ溝６の端部を合わせて棒状部２ａの中央側へスライドせることで、取付具本体３を前記第一取付部２に取り付けることができる。前記胴部分３ｂによって、第二取付部１Ａが構成されている。
また、前記アリ溝６内では、前記棒状部２ａが揺動や回転、及び、スライドできることから、当該取付具１によってガラスパネルＰを構造フレームＡ４に支持させた状態で、図６〜９に示すように、ガラスパネルＰの横スライドや撓みを許容することが可能となる。
従って、例えば、地震が起こって構造体Ａが横揺れした場合には、ガラスパネルＰの正面視においては、各ガラスパネルＰが横スライドするのを許容した状態（図６参照）や、各ガラスパネルＰの転び移動を許容した状態（図７参照）に支持することが可能となると共に、ガラスパネルＰの側面視においては、ガラスパネルＰの傾斜を許容した状態（図８参照）に支持することが可能となる。
また、ガラスパネルＰに強風が作用した場合には、図８・９に示すように、アリ溝６内で棒状部２ａが揺動できると共に、軸芯周りに相対回転できるから、ガラスパネルＰの撓みを許容した状態に支持することが可能となる。
更には、第一取付部２と取付具１との相対的な動きが許容できることで、第一取付部２と取付具１との設置位置精度が低く相互の位置が多少ずれていたとしても、前記相対的な動きによってその誤差を吸収して、無理なくガラスパネルＰを設置することが可能となり、能率良くガラスパネルＰの取付工事を実施することが可能となる。
【００１５】
〔別実施形態〕
以下に他の実施の形態を説明する。
【００１６】
〈１〉前記壁体パネルは、先の実施形態で説明したガラスパネルに限るものではなく、例えば、合成樹脂パネル、木質パネル、石材パネル、セメントパネル、あるいは、その他のパネルなど何れのものでもよく、それらを総称して壁体パネルという。
〈２〉前記第一取付部２は、前記棒状部２ａと繋ぎ部２ｂを備え、第二取付部１Ａは、前記外嵌部３ｂからなる構成に限るものではなく、例えば、図１０に示すように、第一取付部２に前記外嵌部３ｂを備え、第二取付部１Ａに前記棒状部２ａと繋ぎ部２ｂとを備えた構成であってもよい。この場合には、前記外嵌部３ｂのアリ溝開口６ａは、壁面側を向く状態に形成してある。
要するに、第一取付部２と第二取付部１Ａは、前記棒状部２ａと前記外嵌部３ｂとが、前記棒状部２ａの長手方向に沿って相対移動自在に、且つ、互いの軸芯周りに相対回転自在に、且つ、壁面に沿って相対揺動自在に、且つ、前記棒状部２ａの一端部が壁体パネル厚み方向に沿って近接離間する状態に相対揺動自在に嵌合させてあり、その嵌合状態での前記外嵌部３ｂは、前記アリ溝６の開口６ａが前記壁面に対する近接離間方向の何れかに向く状態に設置してあればよい。
また、前記棒状部２ａは、その長さ寸法を、前記取付具１の幅の数倍程度に設定してあるものに限らず、棒状部２ａと前記外嵌部３ｂとの前記棒状部２ａの長手方向に沿った最大相対移動を許容できる状態であれば、前記外嵌部３ｂの幅寸法と同じか、又は、外嵌部３ｂの幅寸法より短い寸法に設定してあってもよい。
〈３〉前記アリ溝６は、先の実施形態で説明した内周面６ｂが、縦断面における内周面部分が曲線となるラッパ形状の凸面に形成したものに限るものではなく、図１１に示すように、縦断面における内周面部分が直線となるラッパ形の凸面に形成してあってもよい。
〈４〉また、アリ溝６の内周面６ｂを凸面形状に形成するのに替えて、図１２・１３・１４に示すように、アリ溝６の内周面は、長手方向のどの部分も内径が同一（又は、ほぼ同一）となる形状に形成して、前記棒状部２ａの外周面を長手方向の中間部が大径となる凸面形状に形成してあってもよい。この実施形態によれば、奥まったアリ溝内周面の加工が単純となると共に、棒状部の外周部の加工には手間が掛かり難いから、より効率よく部品を形成することが可能となる。その結果、コストダウンをかなえることが可能となる。
更には、棒状部２ａは、先の実施形態と同様の形状に形成すると共に、その棒状部２ａに、図１５・１６・１７に示すような外嵌体７を、スライド自在に外嵌させた構造をとることも可能である。この場合の外嵌体７は、両端部に前記アリ溝６の内径寸法より大径の鍔状外れ止め部７ａを設けてあり、長手方向の中央部を盛り上げた凸面に形成し、且つ、外嵌体７と棒状部２ａとが軸芯周りの相対回転を阻止した状態で長手方向に沿ってスライド自在に嵌合させるスプライン部７ｂを設けてある。これらの実施形態によっても、先の実施形態と同様の効果をかなえることが可能である。
〈５〉前記第三取付部１Ｂは、先の実施形態で説明した形式のものに限るものではなく、例えば、図１８に示すように、前記目地２０を貫通する複数のボルト部４ａに替えて、一本のボルト部４ａで構成してあるものであったり、更には、図１９・２０・２１に示すように、４枚の壁体パネルＰの各角部分が合わさる目地２０にボルト部４ａが貫通する状態に取り付き、一部の壁体パネルＰの重量を、セッティングブロックＳを介して受ける受け部４ｂを備えた構成であってもよい。
また、図２２に示すように、複層ガラスからなる壁体パネルに形成した取付用挿通孔に、前記ボルト部４ａを貫通させた状態に取り付ける形式のものであってもよい。

BACKGROUND OF THE INVENTION
The present invention is a wall body in the case where a glass panel (an example of a wall panel) is attached to a structural housing (an example of a structural body) with a mounting bracket (an example of a fixture), such as a glass curtain wall. Regarding the panel support structure, more specifically, the structure is provided with a first mounting portion that can be attached to the wall panel via a fixture, and a second mounting portion that can be attached to the first mounting portion; A third attachment portion that can be attached to a wall panel is provided in the fixture, the second attachment portion is attached to the first attachment portion, and the third attachment portion is attached to the wall body panel, The present invention relates to a wall panel support structure in which the wall panel is supported by the structure.
[0002]
[Prior art]
Conventionally, as this type of wall body panel support structure, as shown in FIG. 23, the first mounting portion 2 is composed of a bar-shaped portion 2a having a horizontal bar shape, and the second mounting portion 1A of the mounting tool 1 is The first mounting portion 2 is constituted by an outer fitting portion 31 having a lateral dovetail 30 that can be received. The dovetail groove 30 is formed so that its opening 30a faces downward, Both side walls 30b are formed in a tapered surface whose opposing distance increases toward the end of the groove, so that the rod-like portion 2a and the outer fitting portion 31 are relatively movable along the longitudinal direction of the first mounting portion 2. In addition, there is one that is fitted so as to be rotatable relative to each other so as to be relatively rotatable around the axis of each other, and in a state in which one end portion of the rod-shaped portion 2a is closely spaced along the thickness direction of the wall panel. (See, for example, JP-A-7-207790).
Moreover, in this wall body panel support structure, considering the convenience at the time of attaching the fixture 1 with respect to the said 1st attachment part 2, the one side part of the dovetail 30 opening is comprised by the attachment / detachment block 32 which can be attached or detached. After the first mounting portion 2 is fitted into the dovetail groove 30, the attachment of the mounting tool 1 to the first mounting portion 2 is completed by screwing the detachable block 32 to the mounting tool 1 body. It was something to do.
[0003]
[Problems to be solved by the invention]
It is already known that the wall panel can be mounted in a state where it can move relative to the structure within a certain range, so that stress during earthquakes and strong winds can be reduced from concentrating on the wall panel mounting area. However, according to the conventional wall panel support structure described above, the rod-like portion 2a and the outer fitting portion 31 are relatively movable along the longitudinal direction of the first attachment portion 2, and Relative rotation is possible around the axis of each other, and one end of the rod-like portion is fitted so as to be relatively swingable in a state of approaching and separating along the thickness direction of the wall panel. Although it can move, it is difficult to mitigate the movement of the wall panel swinging along the wall surface. Such movement occurs between the first mounting part and the second mounting part when an earthquake rolls. If this movement cannot be mitigated, stress concentration occurs at the wall panel mounting location. As a result, there is a problem that the wall panel and the fixture are broken or fall off.
[0004]
Therefore, the object of the present invention is to solve the above-mentioned problems, and even if an earthquake or a strong wind occurs, it is difficult for stress concentration to occur in the mounting portion of the wall panel, and the wall panel can be supported in a stable state. A wall panel support structure is provided.
[0005]

A second attachment portion 1A that can be attached to the portion 2 and a third attachment portion 1B that can be attached to the wall panel P are provided in the fixture 1, and the second attachment portion 1A is provided in the first attachment. In the wall panel support structure in which the wall body panel P is supported by the structure A by attaching the third attachment portion 1B to the wall body panel P, the first attachment portion. 1 and the second mounting portion 1A is constituted by an outer fitting portion 3b having a lateral dovetail groove 6 that can receive the other of the first mounting portion 2 and the second mounting portion 1A. The other of the first attachment portion 2 and the second attachment portion 1A is horizontally long in the direction along the wall surface, and the ant 6 and a connecting portion 2b integrally connected to the rod-like portion 2a through the opening 6a of the dovetail groove 6, the rod-like portion 2a and the outer fitting portion 3b are: The rod-shaped portion 2a is relatively movable along the longitudinal direction of the rod-shaped portion 2a, is relatively rotatable around each axis, and is relatively swingable along the wall surface. The outer fitting portion 3b is fitted so as to be relatively swingable in a state of approaching and separating along the thickness direction of the wall panel, and the opening 6a of the dovetail groove 6 is close to and separated from the wall surface in the fitted state. It is installed in a state facing in any direction.
According to the characteristic configuration of the first aspect of the present invention, the first attachment portion and the second attachment portion are arranged such that one is an outer fitting portion having a laterally arranged dovetail groove and the other is the horizontally long rod-like portion. And the connecting portion, and the rod-like portion and the outer fitting portion are relatively movable along the longitudinal direction of the rod-like portion, and are relatively rotatable around the axis of each other. In addition, the rod-like portion is fitted so as to be relatively swingable along the wall surface and so as to be relatively swingable in a state in which one end portion of the rod-shaped portion is closely spaced along the wall body panel thickness direction. A wall panel that is supported along the surface can be slid left and right along the wall surface, can be swung in a state where the wall surface is obliquely upward or obliquely downward with the connection point as the center, Can swing clockwise or counterclockwise around the connection point, or the vertical axis including the connection point It is possible to swing around. Of course, when the initial mounting state of the wall panel is inclined from the vertical plane, similar movement can be expected based on the initial state.
Accordingly, it becomes possible to allow movement in more directions while maintaining the support state of the wall panel, and stress concentration is less likely to occur at the attachment portion between the structure and the wall panel. Even when it occurs, it becomes possible to support the wall panel without difficulty. As a result, the support state of the wall panel is simply supported, and the stress generated in the wall panel can be relieved, so that the wall panel can be kept stable even if an earthquake or strong wind occurs. It becomes possible to support. Furthermore, even if the installation positions of the first attachment part, the second attachment part, and the third attachment part are slightly displaced depending on the field situation, the positional deviation is externally fitted to the rod-like part. Since it can be absorbed by relative movement, rotation, swinging, and the like with respect to the part, it does not take time and labor to mount the wall panel, and can be proceeded quickly without difficulty.
Further, since the outer fitting portion in the fitting state with the rod-like portion is installed in a state in which the opening of the dovetail groove is directed in any of the proximity and separation directions with respect to the wall surface, the outer fitting portion itself has the dovetail groove opening. Other portions can bear stress as a continuous member, and the force acting between the outer fitting portion and the rod-like portion can be received by the continuous member portion.
In particular, when a force in the direction of pulling off the wall panel is applied from the structure, the rod-shaped portion and the back side of the opening of the dovetail groove are received by contact. It becomes possible to receive evenly at the continuous member (the dovetail side walls) located on both sides of the part. Therefore, compared with the conventional one (the dovetail groove opening is directed downward, and the stress is borne only within the member cross section with a small dovetail bottom of the outer fitting portion), the pulling force to the wall panel When it is possible to demonstrate a stronger wall body panel support force, or to expect the same support force as before, reduce the member cross section of the outer fitting part, It becomes possible to make the fixed part of the wall panel compact.
Furthermore, by providing the dovetail groove in the state in which the opening direction is set in the outer fitting portion as described above, the connecting portion is connected to the opening of the dovetail groove while the rod-like portion is fitted in the dovetail groove. Since it can be positioned, the connecting structure of the rod-shaped portion and the connecting portion, for example, to provide a connecting portion at the center of the rod-shaped portion, to provide a connecting portion at both ends of the rod-shaped portion, or Relative movement between the outer fitting portion and the rod-shaped portion is allowed regardless of the configuration, such as providing a connecting portion at one end of the rod-shaped portion, or providing a connecting portion over the entire length of the rod-shaped portion. can do. Therefore, the design freedom such as the arrangement and posture of the connecting portion can be improved, and the aesthetics can be improved. And since the opening direction of the dovetail groove is set to be in a state in which it approaches either of the approaching and separating directions with respect to the wall surface, the member length of the connecting portion itself is made shorter than the conventional one, which is advantageous in terms of stress. It becomes possible to be in a state.

As illustrated in FIG. 1, the characteristic configuration of the invention of claim 2 is a state in which the third mounting portion 1 </ b> B penetrates the vertical joints between the adjacent wall panels P and sandwiches the edges of both wall panels P. It is where it is formed.
According to the characteristic configuration of the invention of claim 2, in addition to being able to achieve the function and effect of the invention of claim 1, the wall body is compared with the case where the third attachment portion is attached through the wall panel. It is possible to support the panel in a state in which the strength is hardly reduced. As a result, it is possible to withstand a larger external force (an external force acting on the wall panel).
[0007]
4 to 11, the rod-shaped portion 2a has a cylindrical shape, and the dovetail groove 6 has a trumpet on the inner circumferential surface so that the diameter of the dovetail groove 6 increases toward both ends. It is in the shape of the shape.
According to the characteristic configuration of the invention of claim 3, in addition to being able to achieve the operational effect of the invention of claim 1 or 2, the contact area between the rod-like portion and the inner periphery of the dovetail groove is reduced, The frictional resistance during the sliding movement can be reduced, and smooth relative sliding is possible. Furthermore, when the rod-like portion and the outer fitting portion swing relative to each other, the contact portions are likely to move gradually, allowing smooth swinging, and the contact portions are always the same. Compared to the above, local wear can be reduced, and the durability of the parts can be improved.
[0008]
The characteristic configuration of the invention of claim 4 is that, as illustrated in FIG. 5, the length of the rod-like portion 2 a is set larger than the length of the dovetail groove 6, and the connecting portion 2 b is provided at the center portion thereof. It is in place.

Other embodiments will be described below.
[0016]
<1> The wall panel is not limited to the glass panel described in the previous embodiment. For example, the wall panel may be any of a synthetic resin panel, a wood panel, a stone panel, a cement panel, or other panels. These are collectively called wall panels.
<2> The first mounting portion 2 includes the rod-shaped portion 2a and the connecting portion 2b, and the second mounting portion 1A is not limited to the configuration including the outer fitting portion 3b. For example, as shown in FIG.

<4> Further, instead of forming the inner peripheral surface 6b of the dovetail groove 6 into a convex shape, as shown in FIGS. 12, 13, and 14, the inner peripheral surface of the dovetail groove 6 is any part in the longitudinal direction. The inner diameter may be formed in the same shape (or substantially the same), and the outer peripheral surface of the rod-shaped portion 2a may be formed in a convex shape in which the middle portion in the longitudinal direction has a larger diameter. According to this embodiment, the processing of the inner peripheral surface of the recessed dovetail is simplified, and the processing of the outer peripheral portion of the rod-shaped portion is less troublesome, so that it is possible to form parts more efficiently. As a result, the cost can be reduced.
Further, the rod-like portion 2a is formed in the same shape as the previous embodiment, and an outer fitting body 7 as shown in FIGS. 15, 16, and 17 is slidably fitted to the rod-like portion 2a. It is also possible to take a structure. In this case, the outer fitting body 7 is provided with a hook-shaped detachment preventing portion 7a having a diameter larger than the inner diameter dimension of the dovetail groove 6 at both ends, formed in a convex surface with a raised central portion in the longitudinal direction, A spline portion 7b is provided that is slidably fitted along the longitudinal direction in a state where the fitting body 7 and the rod-like portion 2a prevent relative rotation around the axis. These embodiments can also achieve the same effects as the previous embodiments.
