Abstract

L'invention porte sur un procédé d'extrusion par étirage consistant à insérer une âme de polymère tendre dans un poinçon d'extrusion par étirage. A mesure qu'elle avance, l'âme est enrobée d'un matériau cémenteux (C) qui est pompé dans le haut du poinçon de manière à remplir le vide entre les surfaces extérieures de l'âme et les surfaces intérieures du poinçon. Le matériau de construction qui prend légèrement dans le moule d'extrusion par étirage subit ensuite un processus de durcissement à l'aide de dalles de béton réglables (20) avec possibilité de chauffage, refroidissement ou envoi de vapeur ou une combinaison des trois. En outre, en utilisant des éléments pressants (21a, 22) qui compriment les dalles de béton (20) contre le revêtement de béton, on peut éliminer l'excès d'humidité du matériau de construction. Ledit matériau se présente sous la forme d'un unique panneau continu suffisamment rigide pour se passer de support et qui est ensuite découpé à des longueurs données avant emballage par thermorétraction, mise sur palettes et entreposage.
