Abstract

L'invention concerne un profilé en plastique (1) pour un profilé composite en métal et plastique (31). Le profilé en plastique (1) comporte un premier élément de profilé (2) et au moins un deuxième élément de profilé (3), le premier élément de profilé (2) et le deuxième élément de profilé (3) formant conjointement un mécanisme d'encliquetage (4, 9 ; 5, 10 ; 6, 11) au moyen duquel de préférence une liaison par complémentarité de forme entre le premier élément de profilé (2) et le deuxième élément de profilé (3) peut être produite dans le sens de la largeur (x) et dans le sens de la hauteur (y). Le premier élément de profilé (2) et le deuxième élément de profilé (3) se chevauchent de préférence sur une grande surface lorsque la liaison par complémentarité de forme entre le premier élément de profilé (2) et le deuxième élément de profilé (3) est produite, la liaison par complémentarité de forme pouvant être réalisée entre le premier élément de profilé (2) et le deuxième élément de profilé (3) par un encliquetage des éléments (2, 3) du profilé en plastique (1) dans le plan de section transversale (x, y) et la liaison par complémentarité de forme entre le premier élément de profilé (2) et le deuxième élément de profilé (3) étant conçue de telle sorte qu'un déplacement du premier élément de profilé (2) et du deuxième élément de profilé (3) soit autorisé dans une direction longitudinale (z) du profilé en plastique (1) lorsqu'un premier composant métallique (29) est relié au premier élément de profilé (2) de préférence de manière résistante au cisaillement, et qu'un deuxième composant métallique (30) est relié au deuxième élément de profilé (3) de préférence de manière résistante au cisaillement. Le profilé en plastique (1) peut également être réalisé à l'aide de plus de deux éléments de profilé (2, 3), le principe fondamental selon l'invention permettant de produire un profilé composite en plastique et métal (31) dépourvu de cisaillement pouvant être utilisé.
