CA 2332442

The present invention relates to a joint structure for an FRP roofing member wherein two or more FRP sandwich structures are butt joined, an FRP connecting layer extends across the surfaces of both ends of the sandwich structures, and a layer containing a resin distribution medium is provided between the abutting end faces. The present invention also relates to a method for joining FRP roofing members. In accordance with the FRP roofing member joint construction of the present invention, the problems associated with conventional joint structures can be completely overcome, and the ends of the sandwich structures can be easily, firmly and cheaply joined together. As well as ensuring high joint strength and rigidity, an excellent appearance can be achieved.

L'invention porte sur un matériau de plastique armé pour toitures éliminant les risques de rouille, de faible poids, d'une résistance et d'une rigidité suffisamment élevées, et à bon pouvoir isolant, pouvant servir à améliorer les caractéristiques antisismiques d'un bâtiment, et facile à produire dans des formes très attrayantes. Ledit matériau consiste en une structure sandwich composées de deux plaques (3a, 3b) de plastique armé et de nervures (4) les reliant. Lorsqu'on utilise une résine phénolique comme matrice du plastique armé ou qu'on dispose une substance ignifuge sur la surface du matériau pour toitures, ce dernier peut présenter une excellente résistance au feu. De plus, lorsque les extrémités du matériau abutent pour être réunies, on dispose entre les surface un milieu diffuseur de résine et des fibres de renfort sur la totalité desdites extrémités et une résine remplissant le milieu diffuseur qui diffuse dans les éléments de renfort et assure la liaison.
