【０００１】
【発明の属する技術分野】
本発明は、湾曲する曲面パネルを形成するための曲面パネル用形材を用いてバス停留所の屋根等を形成する曲面パネルに関する。
【０００２】
【従来の技術】
一般に、アルミニウム合金の押出形材は、その断面形状を自在に設計できるため、複数の押出形材をそれらの押出方向と直交する断面方向に沿って互いに嵌合することにより、任意のデザインを容易に形成することができる。
例えば、図８(Ａ)に示すように、押出方向と直交する断面全体が緩くカーブした中空形材１３２同士を、図８(Ｂ)に示すように、それらの両端の同様にカーブする断面形状の雄・雌嵌合部１３４，１３６によって互いに嵌合１３８することにより、全体が同じ曲率で連続して湾曲する曲面パネル１３０を形成することができる。また、上記雄・雌嵌合部１３４，１３６のよる嵌合を繰り返すことにより、図示しない丸い断面の円筒形の曲面パネルを形成することもできる。
【０００３】
更に、押出方向と直交する断面のカーブが互いに異なり、その断面両端の雄・雌嵌合部１３４，１３６を有する中空形材１３２同士を互いに嵌合１３８することにより、異なる曲率を併有する曲面パネル(１３０)を形成することもできる。
しかしながら、互いに回転して嵌合１３８する雄・雌嵌合部１３４，１３６を用いる場合、押出精度が高くないとスムースな嵌合操作が行いにくく、且つ形成される曲面パネルの断面形状が設計通りに形成し難いという問題がある。
更に、断面のカーブが互いに異なる中空形材１３２同士を嵌合１３８しても、得られる曲面パネル(１３０)の表面の湾曲面の方向は常に同じ方向になる。
ところで、市街地や公共施設等のデザインの多様化が求められる昨今においては、単一の曲率のみからなる上記曲面パネル１３０や複数の曲率を併有するものの同じ方向のみに湾曲する曲面パネル(１３０)では、個性的で多様なデザインニーズに対応しにくい、という問題もあった。
【０００４】
一方、複数の中空形材１３２同士を嵌合１３８して形成した曲面パネル１３０は、各形材１３２を位置固定する必要がある。このため、互いに嵌合１３８した隣接する形材１３２同士をその雄・雌嵌合部１３４，１３６付近において、別途図示しない構造部材又はこれに支持される補助部材にボルト・ナットやネジ止め等により固定している。係るボルト締結作業やネジ止め作業は曲面パネル１３０の組立工数や施工工数を増やしコスト高を招く、という別の問題もあった。
更に、前記の曲面パネル１３０を形成するため、ハニカムサンドイッチパネルを予めその製造時から、カーブする断面として曲面パネルを形成することも可能であるが、係るサンドイッチパネルは製造コストが嵩むという問題があった。
【０００５】
【発明が解決すべき課題】
本発明は、容易な嵌合により曲面パネルを形成でき、多様なデザインニーズに容易に形成できる曲面パネル用形材を用いて、カーブ方向が自在で任意数の湾曲面を有し且つ組立工数や施工工数を低減し得る比較的大型の曲面パネルを、安価に提供することを課題とする。
【０００６】
【課題を解決するための手段】
上記課題を解決するために、本発明による曲面パネル（請求項１）は、アルミニウム合金の押出形材からなり、その押出方向と直交する断面において略全体に設けたカーブした本体部分と、この本体部分の両端に互いに直線移動して嵌合する嵌合部と、を含む複数の曲面パネル用形材同士を、互いの嵌合部間に接着剤を介して嵌合することで形成される曲面パネルであり、上記嵌合部間に接着剤の余剰分を受け入れる間隙が形成されている、ことを特徴とする。
【０００７】
これによれば、隣接する曲面パネル用形材の嵌合部同士を精度良く容易に嵌合できると共に、後述するカーブ方向が交互に異なる複数の湾曲面を有する曲面パネルを容易に形成することができる。更に、曲面パネル用形材同士をそれらの嵌合部間に接着剤を介して嵌合して形成するため、互いに嵌合した形材同士を別途の部材を介してボルトやネジ止めすることなく、相互に直接接合することができ、曲面パネルの組立工数や施工工数を低減し且つコスト低減を図ることもできる。しかも、隣接する各形材における互いに嵌合し合う嵌合部間で、塗布した接着剤のうち余剰分を吸収でき、薄くて均一な膜厚の接着剤層を形成できるため、所要の接着強度によって複数の形材同士を強固且つ一体に接合した曲面パネルとすることができる。従って、多様なデザインニーズに容易に対応でき、任意且つ自在に形成することが可能な曲面パネルを提供することが可能となる。
【０００８】
尚、前記接着剤には構造用接着剤（ＪＩＳＫ６８００）を用いることが望ましい。
また、前記間隙には、互いに嵌合し合う嵌合部の何れかまたは双方に形成した凹部は勿論のこと、例えば複雑な断面形状からなる雄・雌嵌合部間において、形材製造（押出）時の公差により形成される隙間も含まれ得る。
更に、前記曲面パネルの用途には、屋根ユニットまたはその一部、あるいは、壁ユニットまたはその一部が含まれる。即ち、カーブ方向が異なる複数の湾曲面を有する屋根ユニットまたは壁ユニットを構成でき、多様なデザインニーズに容易に容易に対応することが可能となる。上記屋根ユニットは、例えばバス停留所や駅構内におけるベンチの上方、あるいは、駅前広場等における歩行者用通路の上方に用いられる。また、上記壁ユニットは、例えば公共的スペースにおけるデザイン間仕切壁等に使用される。更に、係る屋根・壁ユニットは、例えば鉄道車両の車体や航空機の機体、あるいは、それらの一部に適用することも可能である。
【０００９】
また、前記曲面パネル用形材は、その本体部分の両端において、それぞれ本体部分におけるカーブした両端の接線と平行な直線状の嵌合部と、を含んでいる、曲面パネル（請求項２）も本発明に含まれる。
更に、前記曲面パネル用形材の本体部分が、押出方向と直交する断面の長手（幅）方向に沿う寸法の８０％以上を占める、曲面パネル（請求項３）も本発明に含まれる。
【００１０】
これらによれば、各曲面パネル用形材を嵌合しても、隣接する形材間における各嵌合部による直線部分が目立つことなく、複数の形材の表面が全体に連続した１つのカーブ、または交互に異なる方向の複数のカーブを連続的に形成ししつ、各形材を嵌合できるため、曲面パネルのデザインを損なわずにすることができる。
尚、本体部分の前記寸法を８０％以上としたのは、これが８０％未満になると形材同士の嵌合部に沿って形成される平坦面が目立ち易くなるので、係る事態を防ぐためである。
【００１１】
また、前記曲面パネル用形材同士を互いに嵌合部で嵌合してカーブ方向が共通する１つの湾曲面を形成する、曲面パネル（請求項４）も本発明に含まれる。
これによれば、各形材同士の嵌合が直線移動によって容易に行え、且つ同じ方向にカーブする曲面パネル（円筒体を含む）を容易に組立てることができる。
更に、前記曲面パネル用形材同士を互いに嵌合部で嵌合して互いにカーブ方向が異なる複数の湾曲面を形成すると共に、少なくとも隣接するカーブ方向が異なる湾曲面間に各形材の嵌合部が位置している、曲面パネル（請求項５）も本発明に含まれる。
これによれば、カーブ方向が異なる複数の湾曲面を有する曲面パネルを容易に得られ、多様なデザインニーズに容易に容易に対応できる曲面パネルを任意且つ自在に形成することができる。尚、カーブ方向が異なる複数の湾曲面とは、例えば２つの向きが異なる隣接するカーブが形成するＳ形状断面や、多数のカーブが交互に逆向きに隣接する波形状断面が挙げられ、且つそれらの一部も含まれる。
【００１２】
【発明の実施の形態】
以下において本発明の実施に好適な形態を図面と共に説明する。
図１(Ａ)は、本発明に用いられる一形態の曲面パネル用形材１の断面を示す。
係る形材１は、ＪＩＳ：Ａ６０６３等のアルミニウム合金からなり、その押出方向と直交する図１(Ａ)に示す断面において、全体が同じ曲率でカーブした本体部分２と、図示で右端に位置する雄型嵌合部６と、図示で左端に位置する雌型嵌合部１０と、これらの間に位置してに偏平にカーブした中空部４とを有する。形材１は、係る断面形状を図１(Ａ)の奥行き方向に沿って数メートル程度の長さに渉り連続して有する。
上記本体部分２は、互いに同心で且つ平行なカーブ片３，３とからなり、図１(Ａ)に示す断面の長手（幅）方向に沿う寸法の８０％以上を占めている。
また、上記雄型嵌合部６と雌型嵌合部１０とは、本体部分２におけるカーブした両端における接線と平行で且つ直線状に形成され、図１(Ａ)に示す断面の長手（幅）方向に沿う寸法において、両者合計でも２０％未満とされている。
【００１３】
図１(Ａ)の右端に示すように、曲面パネル用形材１の雄型嵌合部６は、図示で上下方向の中央に位置する断面台形の凹部７と、その上下に対称且つ平行に右側に突出する一対の断面先尖形状の凸条８，８と、これらの上下に隣接し且つ本体部分２のカーブ片３，３の端に隣接する段部９，９とを有する。係る凹部７や各凸条８の中心線及び各段部９は、本体部分２のカーブした右端における接線と平行で且つ直線状に形成されている。
また、雌型嵌合部１０は、図１(Ａ)の左端に示すように、図示で上下方向の中央に位置する断面台形の凸部１１と、その上下に対称且つ平行に右側に凹む断面台形の一対の凹溝１２,１２と、これらの上下に隣接する傾斜片１３,１３と、本体部分２のカーブ片３,３の端に隣接する互いに平行な突出片１４,１４とを有する。係る凸部１１や各凹溝１２の中心線及び各突出片１４は、本体部分２のカーブした左端における接線と平行で且つ直線状に形成されている。
【００１４】
以上のような曲面パネル用形材１の左右両端に、同じ断面を有する曲面パネル用形材１ａ，１ｂを嵌合すると、図１(Ｂ)及び(Ｃ)に示すような嵌合状態になる。
即ち、図１(Ｂ)に示すように、形材１の雌型嵌合部１０における各凹溝１２内には左側に隣接する形材１ｂの雄型嵌合部６における各凸条８が、雄型嵌合部６の凹部７内に雄型嵌合部６の凸部１１がそれぞれ直線移動して進入し、雌型嵌合部１０の各突出片１４は上記雄型嵌合部６の各段部９内に位置する。
また、図１(Ｃ)に示すように、形材１の雄型嵌合部６における各凸条８は、その右側に隣接する形材１ａの雌型嵌合部１０における各凹溝１２内に、雄型嵌合部６の凹部７内には上記雌型嵌合部１０の凸部１１が各々直線移動して進入し、雄型嵌合部６の各段部９内には上記雌型嵌合部１０の各突出片１４が位置する。
【００１５】
図１(Ｂ)及び(Ｃ)に示すように、形材１,１ａ,１ｂの各嵌合部６，１０は、互いに直線移動して容易に嵌合し合い、両嵌合部６，１０を含む形材１,１ａ,１ｂの両端部分のみは直線で構成され、その表裏面は、図示で奥行き方向に沿って細長い平坦面を形成する。係る嵌合部６，１０を両端に有する曲面パネル用形材１を複数用いることにより、カーブする方向が同じで１つの湾曲面のみを有する前述した曲面パネル１３０は勿論のこと、後述するカーブする方向が交互に異なる複数の湾曲面を有する曲面パネルをも容易に形成することが可能となる。
【００１６】
更に、図１(Ｂ)及び(Ｃ)に示すように、雄・雌嵌合部６，１０における凹部７と凸部１１との間、一対の凸条８と凹溝１２との間、及び、各凸条８の基部の上下と隣接する傾斜片１３との間には、図示で奥行き方向に沿って断面台形又は菱形の間隙１６，１８が形成される。
例えば、図２(Ａ)に示すように、形材１の雄型嵌合部６に予め構造用接着剤Ｓを塗布した場合、図２(Ｂ)に示すように、形材１ａと雄・雌嵌合を行った際に、余剰となった接着剤１７,１９を各間隙１６,１８内において吸収することができる。この際、形材１,１ａは図２(Ｂ)中の部分Ｘ_１，Ｘ_２で当接し、両者間に形成される間隔が一定に保持されるので、接着剤Ｓの厚みが適正となる。従って、所要の接着強度をもって複数の形材１同士を強固且つ一体に接合することができ、後述する曲面パネルを少ない工数で且つ安価に提供し得る。
【００１７】
図３(Ａ)は、本発明に用いられる異なる形態の曲面パネル用形材２０の断面を示す。この形材２０も前記のアルミニウム合金からなり、その押出方向と直交する図３(Ａ)に示す断面において、全体が同じ曲率でカーブした本体部分２１と、図示で右端に位置する雄型嵌合部２４と、図示で左端に位置する雌型嵌合部３０と、これらの間に位置して偏平にカーブした中空部２３とを有する。
上記本体部分２１は、互いに同心で且つ平行なカーブ片２２，２２とからなり、図３(Ａ)に示す断面の長手(幅)方向に沿う寸法の約９０％を占めている。
また、上記雄型嵌合部２４と雌型嵌合部３０とは、本体部分２１におけるカーブした両端における接線と平行で且つ直線状に形成され、図３(Ａ)に示す断面の長手（幅）方向に沿う寸法は、両者合計でも全体の約１０％を占めるに過ぎない。
【００１８】
図３(Ａ)の右端に示すように、形材２０の雄型嵌合部２４は、図示で上下方向の中央に位置する断面台形の凹部２６と、その上下に対称且つ平行に右側に突出する断面台形の凸条２８，２８と、これらの上下に隣接する垂直片２９とを有する。係る凹部２６や各凸条２８の中心線は、本体部分２１のカーブした右端における接線と平行で且つ直線状に形成されている。
一方、図３(Ａ)の左端に示すように、形材２０の雌型嵌合部３０は、図示で上下方向の中央に位置する断面台形の凸部３１と、その上下に対称且つ平行な断面台形の凹溝３２,３２と、これらの上下に隣接する垂直片３３,３３とを有する。
上記凸部３１や各凹溝３２の中心線は、本体部分２１のカーブした左端における接線と平行で且つ直線状に形成されている。また、上側の垂直片３３の上端において、本体部分２１における上方のカーブ片２２の左端における接線と平行で且つ図示で上側に偏寄してに左側に水平に突出する水切り片３４を一体に有する。
【００１９】
曲面パネル用形材２０の左右両端に、同じ断面を有する形材２０ａ，２０ｂを嵌合すると、図３(Ｂ)に示すような嵌合状態になる。
即ち、図３(Ｂ)の右側に示すように、形材２０の雄型嵌合部２４における各凸条２８は、その右側に隣接する形材２０ａの雌型嵌合部１０における各凹溝３２内に、雄型嵌合部２４の凹部２６内には上記雌型嵌合部３０の凸部３１がそれぞれ直線移動して進入する。また、雄型嵌合部２４における上側の垂直片２９に隣接する外側面に、上記雌型嵌合部３０の水切り片３４が面接触する。
一方、図３(Ｂ)の左側に示すように、形材２０の雌型嵌合部３０における各凹溝３２内には左側に隣接する形材２０ｂの雄型嵌合部２４における各凸条２８が、雄型嵌合部３０の凸部３１は上記雄型嵌合部６の凹部２６内それぞれ直線移動して進入する。また、雌型嵌合部３０の水切り片３４は、形材２０ｂの上記雄型嵌合部２４における上側の垂直片２９に隣接する外側面に面接触する。
【００２０】
図３(Ｂ)に示すように、形材２０,２０ａ,２０ｂの各嵌合部２４，３０は、互いに直線移動して嵌合し合い、両嵌合部２４,３０を含む形材２０,２０ａ,２０ｂの両端部分のみは直線状に構成され、その表裏面は図示で奥行き方向に沿って細長い平坦面を形成する。嵌合部２４，３０を両端に有する曲面パネル用形材２０を複数互いに嵌合することで、カーブする方向が１つの湾曲面のみを有する曲面パネルは勿論、後述するカーブする方向が交互に異なる複数の湾曲面を有する曲面パネルを容易に形成することも可能となる。また、形材２０,２０ａ,２０ｂの嵌合部分に沿って水切り片３４が外側面に沿って配置されるので、後述する屋根ユニット等の曲面パネルに活用した場合、優れた雨仕舞い機能を発揮し得る。
【００２１】
更に、図３(Ｂ)に示すように、雄・雌嵌合部２４，３０における凹部２６と凸部３１との間、及び各凸条２８の各凹溝３２との間には、図示で奥行き方向に沿って断面台形の間隙３６，３８が形成されている。形材２０の嵌合部２４，３０に予め構造用接着剤Ｓを塗布した場合、図３(Ｂ)に示すように、形材２０ａ，２０ｂと嵌合をした際、余剰となった接着剤３７，３９を各間隙３６，３８内にて吸収できる。また、雄・雌嵌合部２４，３０は、それらの垂直片２９，３３が互いに当接することにより、両者間に挟持される接着剤Ｓの厚みを適正できるため、必要な接合強度が容易に得られ、且つ一定に安定して保つことができる。従って、所要の接着強度をもって複数の形材２０同士を強固且つ一体に接合することができ、後述する曲面パネルを少ない工数で且つ安価に提供できる。
【００２２】
図４は、前記形材１又は形材２０を用いた本発明の曲面パネルに関し、図４(Ａ)は、複数の形材１又は形材２０同士を嵌合し、カーブする方向が異なる二つの湾曲面４２，４３を有する断面略Ｓ字形の曲面パネル４０を示す。図４(Ａ)中で左右両端には、一端に嵌合部のない形材１ｃ，１ｄ（２０ｃ，２０ｄ）が必要に応じて配置される。
また、図４(Ｂ)は、複数の形材１同士又は形材２０同士を嵌合し、カーブする方向が交互に異なる３つの湾曲面４６，４８，４８を有する断面略逆Ｗ字形の曲面パネル４４を示す。図４(Ｂ)中で左右両端にも、一端に嵌合部のない形材１ｅ，１ｆ(２０ｅ，２０ｆ)が必要に応じて配置される。
ところで、曲面パネル４０，４４において、互いに嵌合する複数の形材１又は形材２０同士は、予め塗布した前記接着剤Ｓにて互いに接合されている。即ち、曲面パネル４０，４４は一体物のユニットである。尚、曲面パネル４０，４４を形成する途中において、１つの湾曲面４２，４６のみを有する前述した曲面パネル１３０と同様の曲面パネルを形成できることも明らかである。
【００２３】
図４(Ｃ)は、前記曲面パネル４０を屋根ユニットとして用いたバス停留所５０を示す。即ち、停留所５０は、プラットフォーム５１上に植設された複数の支柱５２の上端に跨って直かに又は図示しない梁材を介して屋根ユニットたる曲面パネル４０を固定したものである。また、図４(Ｄ)は、前記曲面パネル４４を屋根ユニットとして用いたバス停留所５４を示し、この停留所５４は、プラットフォーム５６上に植設された複数の支柱５８の上端に跨って直かに又は図示しない梁材を介して屋根ユニットたる曲面パネル４４を固定したものである。
以上のようなバス停留所５０，５４は、その屋根を構成する屋根ユニットたる曲面パネル４０，４４により、単純な片寄せ屋根や蒲鉾形状の屋根を有する一般的なデザインの停留所に比べて、ユニークで個性的なデザインを呈し、公共的スペースにおける景観を多様化することに寄与することができる。尚、雨仕舞いの観点から停留所５０,５４の屋根ユニットとなる曲面パネル４０,４４には、前記水切り片３４を嵌合部３０に有する前記形材２０を用いることが望ましい。
【００２４】
図５(Ａ)及び(Ｂ)は、前記形材１又は形材２０を用いて連続する波形にした曲面パネル６０に関する。曲面パネル６０は、複数の形材１同士又は形材２０同士を嵌合し、カーブする方向が交互に異なる湾曲面６１，６２を有する。係る曲面パネル６０は、屋根付通路６４の屋根ユニットに使用される。尚、図５(Ｂ)において曲面パネル６０の両側の端面は、波形を呈する図示しない端部材が固定される。即ち、通路６４は、路面Ｇから一対ずつ平行に立設するポスト６５と、各ポスト６５の上端に跨って固定した梁６６と、一対のポスト６５間を連結する桁６８とにより、予め屋根ユニットを支持する構造体が形成される。梁６６の上に曲面パネル６０の各湾曲面６２の底面に接してこれを固定する支持材６７を取付ける。各支持材６７を介して、曲面パネル６０を通路６４の長手方向に沿って波形を呈するように固定し、屋根付通路６４が得られる。従って、係る通路６４はその屋根を構成する曲面パネル６０により、一層ユニークで個性的なデザインを呈し、公共的スペースにおける景観を多様化することに寄与することができる。
尚、曲面パネル６０は予め形材１，２０を接着剤により適当なスパン毎に分割して一体化されていると共に、現場において各分割体を互いに接着して形成される。
【００２５】
図６は、前記形材１を用いた更に異なる形態の曲面パネルに関する。
図６(Ａ)は、複数の形材１，１同士を嵌合し、断面半円形を呈する複数の湾曲面７２，７３，７４が交互に異なる方向にカーブする曲面パネル７０を示す。即ち、隣接する湾曲面７２〜７４における湾曲する方向の変化点（曲率の変化点）Ｙで、互いに隣接する形材１，１のカーブ方向を変えて配置し嵌合することにより、一種類の形材１のみで曲面パネル７０を形成することができる。これにより、深い波形状に連続した曲面を容易に形成できる。
また、図６(Ｂ)は、複数の同じ形材１,１同士を嵌合し、断面が浅い円弧形を呈する複数の湾曲面７７,７８,７９が交互に異なる方向にカーブする曲面パネル７６を示す。この曲面パネル７６も湾曲面７７〜７９における湾曲する方向の変化点Ｙで隣接する形材１，１のカーブ方向を変えて配置し嵌合したものである。これにより、一種類の形材１で断面が浅い円弧形の湾曲面７７〜７９が交互に反転して連続する浅い波形状の曲面を容易に形成することができる。
尚、曲面パネル７０，７６も、互いに嵌合した複数の形材１，１を、予め塗布した前記接着剤Ｓにより互いに一体化して接合されている。また、水切片３４を有する前記形材２０をこれらに用いる場合には、水切片３４の先端を下向きにして配置するため、水切片３４を突設する位置が異なる二種類の形材が必要となる。
【００２６】
図６(Ｃ)は、前記曲面パネル７０を壁ユニットとして用いた間仕切壁８０を示す。この間仕切壁８０は、その凹んだ湾曲面７２〜７５内の中間に水平な棚板又はデスク８２を固定している。この棚板８２を用いて、公衆電話や各種展示品等の受け機能を持たせたり、或いはオフィス等におけるプライベートデスクとして活用することも可能である。
また、図６(Ｄ)は、前記曲面パネル７６を壁ユニットとして用いた間仕切壁８４を示し、湾曲面７７〜７９の裏面にカーブした案内等の表示物８６を固定したり、或いは湾曲面７７内等に照明灯８８を取付けている。
以上の間仕切壁８０，８４によれば、複数の湾曲面が連続した波形として形成された壁面を形成するので、役所や駅舎内等のスペースをカーブを伴って自在に仕切ることができ、柔らかくて落ち着いた屋内空間を演出することができる。
【００２７】
本発明は以上において説明した各形態に限定されるものではない。
例えば、前記形材１（２０）における嵌合部には、図７(Ａ)に示すように、図示で上下の垂直片９１の間に断面台形の凸条９２を有する雄型嵌合部９０と、凸条９２を受け入れる相似形断面の凹溝９５を中間に有し且つ上下端から水平に且つ互いに対称に延びる断面Ｌ字形の突出片９６，９６を有する雌型嵌合部９４とを用いることもできる。凸条９２と凹溝９５との間隙には接着剤Ｓが充填される。そして、外側に位置する突出片９６は隣接する垂直片９１に接触又は近接すると共に、形材１,１間から万一進入した雨水を受ける樋としての機能も果たす。
また、図７(Ｂ)に示すように、形材１(２０)の右端には上記と同じ雄型嵌合部９０を、形材１(２０)の左端には同様の凹溝９５を中間に有し且つ上下端から水平に延びる厚肉のフランジ９７を有する雌型嵌合部９４を設けても良い。しかも、各フランジ９７の内側には隣接する凸条９２の各傾斜面９３に接触する断面Ｏ形のパッキン９８を、図示で奥行き方向に沿って保持させたものである。この形態では、パッキン９８は図７(Ｂ)で上側のみに保持し、下側は省略しても良い。尚、凸条９２と凹溝９５との間には、予め接着剤Ｓが塗布してある。
【００２８】
更に、図７(Ｃ)に示すように、形材１(２０)の嵌合部は、右端の垂直片１０１から平行に突出する断面が細長三角形の凸条１０２を３個突設し、上表面に沿って設けた段部１０４の中間には断面矩形の凹み１０３を有する嵌合部１００と、左端の上記各凸条１０２を受け入れる相似形断面の凹溝１０６を３個中間に有し、且つ上端から水平に延びて上記段部１０４の上に位置するフランジ１０７を設けた嵌合部１０５とからなる。この形態では、段部１０４とフランジ１０７の間から進入した雨水は樋とし機能する凹み１０３内に入った後、外部に排水される。尚、各凸条１０２と凹溝１０６間には、予め前記接着剤Ｓが塗布されている。
また、図７(Ｄ)に示すように、形材１(２０)の右端には段部１０４の中間に底広断面の凹み１０８を有する上記同様の嵌合部１００を設け、左端に上記と同じ嵌合部１０５を設け、且つ凹み１０８に図示で上側面がフランジ１０７の内側面に密着するパッキン１０９を図示で奥行き方向に沿って保持させても良い。

[Prior art]
In general, extruded profiles of aluminum alloys can be freely designed in cross-sectional shape, so it is easy to design any shape by fitting multiple extruded profiles together along the cross-sectional direction perpendicular to the direction of extrusion. Can be formed.
For example, as shown in FIG. 8 (A), the hollow sections 132 whose entire cross-sections orthogonal to the extrusion direction are gently curved can be similarly curved as shown in FIG. 8 (B). By fitting 138 with each other by the male / female fitting portions 134 and 136, the curved panel 130 that is continuously curved with the same curvature can be formed. Further, by repeating the fitting by the male / female fitting portions 134 and 136, a cylindrical curved panel having a round cross section (not shown) can be formed.
[0003]
Furthermore, curved panels having different curvatures are obtained by mutually fitting 138 hollow shape members 132 having male and female fitting portions 134 and 136 at both ends of the cross section, which have different cross-sectional curves orthogonal to the extrusion direction. (130) can also be formed.
However, when using the male / female fitting portions 134 and 136 that rotate and engage 138 with each other, it is difficult to perform a smooth fitting operation unless the extrusion accuracy is high, and the cross-sectional shape of the formed curved panel is as designed. There is a problem that it is difficult to form.
Further, even if the hollow members 132 having different cross-sectional curves are fitted 138, the curved surfaces of the curved panel (130) obtained always have the same direction.
By the way, in recent years when diversification of design of urban areas and public facilities is required, the curved panel 130 having only a single curvature or the curved panel (130) having a plurality of curvatures but curved only in the same direction. There was also a problem that it was difficult to meet individual and diverse design needs.
[0004]
On the other hand, the curved panel 130 formed by fitting 138 a plurality of hollow shapes 132 needs to fix the positions of the shapes 132. For this reason, adjacent members 132 that are fitted to each other 138 are connected to structural members (not shown) or auxiliary members supported by bolts, nuts, screws or the like in the vicinity of the male and female fitting portions 134 and 136. It is fixed. Such bolt fastening operation and screwing operation have another problem that the number of assembling steps and construction man-hours of the curved panel 130 are increased and the cost is increased.
Further, in order to form the curved panel 130, it is possible to form a curved panel as a curved cross section from the time of manufacturing the honeycomb sandwich panel in advance. However, such a sandwich panel has a problem that the manufacturing cost increases. It was.
