Abstract

L'invention concerne un procédé de fabrication en continu d'éléments de construction (B) comportant deux nattes de grillage (M, M') plates parallèles, lesquelles sont constituées par des fils longitudinaux et transversaux croisés et soudés aux points de jonction, par des fils d'entretoise (S, S') droits maintenant les nattes de grillage en un écartement mutuel prédéfini, et par un élément isolant disposé entre les nattes de grillage et traversé par les fils d'entretoise. Selon ce procédé, deux nattes de grillage sont placées en parallèle dans un canal de production (2), en un écartement mutuel correspondant à l'épaisseur voulue pour l'élément de construction. Une plaque isolante (I, I') en matériau calorifuge est disposée dans l'espace se trouvant entre les nattes de grillage parallèles et, simultanément, plusieurs fils d'entretoise sont enfoncés à travers au moins une des nattes de grillage et l'élément isolant, à partir d'au moins un côté alternativement en sens inverse à l'oblique dans des plans perpendiculaires aux plans des nattes de grillage, lesdits fils d'entretoise étant alors soudés aux fils (L, L'; Q, Q') du grillage des nattes. La présente invention porte également sur un dispositif pour réaliser ce procédé et sur un élément de construction ainsi fabriqué.
