Abstract

Le problème à résoudre dans le cadre de cette invention concerne la fabrication à bas coût d’un panneau à la fois léger et très rigide. La solution proposée consiste à fabriquer un panneau comprenant une paire de pièces de panneau présentant une partie de surface plate, des parties saillantes de fixation disposées autour de la partie de surface plate, qui sont formées périodiquement de manière saillante dans une direction définie en fonction de la partie de surface plate, et présentant des surfaces de paroi et des faces supérieures formées sur les parties de pointe des surfaces de paroi, ainsi que des parties renfoncées de fixation entourées par les surfaces de paroi des parties saillantes de fixation et de la partie de surface plate. Les faces supérieures et la partie de surface plate sont mises mutuellement en contact en fixant les parties saillantes de fixation de l’une des pièces de panneau dans les parties renfoncées de fixation de l’autre pièce de panneau.
