Abstract

La présente invention porte sur des éléments de construction composites qui se présentent sous la forme d'une barre à section rectangulaire et qui peuvent être utilisés pour fabriquer des structures préfabriquées, telles que des scènes de concert à montage rapide, des pavillons d'exposition et de vente ou des structures de bâtiment. L'élément de construction composite de cette invention se présente sous la forme d'une barre à section rectangulaire comportant des lamelles externes et une couche interne intercalée entre lesdites lamelles. Le contour extérieur de l'élément de construction composite formé par les lamelles externes, qui sont composées d'un matériau en feuille, est conçu de façon qu'il soit fermé, tandis que la couche interne est composée d'une matière de charge mousse légère. La couche interne peut comporter sur toute sa longueur une rainure longitudinale dans laquelle une unité de fixation peut être placée. Cette invention réduit la consommation de bois et augmente la résistance de l'élément de construction.
