Description
Plastic:CFRP)等の複合材の適用範囲が一次構造へ拡大している。そして、複合材が軽量であるというメリットを生かして、構造の軽量化を達成するためにはファスナを用いない継手が好ましい。
継手の例としては、溝部が形成されて、この溝部に部材(例えば板材)を差し込む、所謂パイ(π)型の継手が挙げられる。
そこで、溝部の底面の全面には、部材と嵌め合わされる第1嵌合形状が形成される。すなわち、部材にも第1嵌合形状に応じた嵌合形状が形成されており、溝部の底面の第1嵌合形状と部材の嵌合形状とが嵌め合わされる。これにより、部材は、第1嵌合形状と合致する位置にのみ嵌め合わされる。
なお、第1嵌合形状は、例えば、溝部の幅の中心線を軸に左右対称な形状、又は左右非対称な形状である。
上側スキン3及び下側スキン5は、主翼1の外形を構成し、空力面も兼ねる薄板であり、前側スパー7、後側スパー9及びストリンガ(図示省略)とともに主翼1に働く引っ張り荷重や、圧縮荷重の一部を受け持つものである。
前側スパー7と後側スパー9との間を、主翼1の翼長方向に延びる補助部材である複数のストリンガが上側スキン3又は下側スキン5の内側面に配置される。
パイ型継手20は、本体部材24を形成する一対のL字型部材28の二面が対向して配置されて溝部22が形成され、位置決め部材26の上面26Aが溝部22の底面となるように構成される。
そして、差し込まれた板材30の下面は、位置決め部材26の上面26Aと接合される。
このように、パイ型継手20を用いた接着により、ファスナが用いられることなく、板材30は母材21に接合される。
このように、嵌合形状32A−1は、溝部底面22Aの全体に渡って形成されているため、面で板材30の位置決めを行うものである。換言すると、嵌合形状32A−1は、溝部22の幅方向に対する板材30の位置決めを行う。
このV字型の嵌合形状32A−1が、溝部22の長手方向に向かって形成される。
なお、溝部底面22Aの全面とは、略全面も含み、例えば溝部底面22Aの長手方向の両端部近辺に嵌合形状32A−1が形成されない、溝部底面22Aの長手方向の中央部近辺に嵌合形状32A−1が形成されない、又溝部底面22Aの長手方向の複数個所に嵌合形状32A−1が形成されない等、溝部底面22Aの一部に嵌合形状32A−1が形成されていなくてもよい。
上記所定位置とは、例えば溝幅の中心のように、溝部22を形成するL字型部材28の二面に板材30が接触しない位置である。板材30が溝部22を形成するL字型部材28の二面に接触すると、板材30の左右に均等に接着剤が充填できなくなる。
一方、板材30におけるパイ型継手20との接合面には、パイ型継手20の溝部底面22Aと嵌め合わされる嵌合形状32B−1,32B−2が形成される。
以下、本発明の第1変形例について説明する。
一方、板材30には、嵌合形状32A−1と嵌め合わされる嵌合形状32B−1として、凹型の円弧形状とその左右に高さの異なる平坦形状が形成される。
以下、本発明の第2変形例について説明する。
一方、板材30には、嵌合形状32A−1と嵌め合わされる嵌合形状32B−1として、一方に斜面が形成され、他方に段差を有する平坦形状が形成される。
以下、本発明の第3変形例について説明する。
一方、板材30には、嵌合形状32A−2と嵌め合わされる嵌合形状32B−2として、切欠き形状が形成される。
