Abstract

La présente invention concerne un panneau structural composite bois-verre destiné à la construction, dans lequel les matériaux revêtent un caractère à la fois fonctionnel, esthétique et structural. Ce panneau comprend une sous-structure de bois (5) et deux vitres structurales feuilletées simples (7), soit une sur chaque côté de la sous-structure, le collage étant effectué au moyen d'un adhésif structural monocomposé (8) à comportement semi-rigide après le séchage. La sous-structure est constituée par plusieurs plaques de bois (1) disposées en parallèle, séparées par des blocs de bois (2) et fixées avec des tiges d'acier filetées (3). Lorsqu'il est utilisé comme paroi, le panneau peut également comprendre des fenêtres coulissantes, l'une sur la face intérieure (6) et l'autre sur la face extérieure (14), de manière à permettre une ventilation.
