Abstract

L'invention porte sur des systèmes et des procédés de construction de structures de mur composite, dans lesquelles on fournit des plaques opposées définissant un espace transversal. Une pluralité d'ensembles connecteurs traversants, enjambant l'espace transversal entre les plateaux, sont fixés sur le plateau opposé. On applique un mécanisme de liaison sur les ensembles de liaison traversants à partir de l'extérieur d'au moins l'une des plaques et on le fixe sur les parties des ensembles de liaison traversants dans l'espace transversal. L'espace transversal peut être rempli d'un matériau de remplissage après la fixation des plaques opposées sur la pluralité des ensembles de liaison traversants.
