Abstract

L'invention concerne un element d'angle d'un corps creux anguleux, par exemple un conteneur de navire formant un ensemble de construction. Une corniere en acier (10) disposee dans l'angle et un element de construction (28) parallele le long de celle-ci supportent les elements d'angle de plaques de materiau leger (20) et (22) au moyen de brides paralleles a celles-ci. Un element de soutenement en matiere plastique (28), renforce par des filins resistant a la traction est relie rigidement a la corniere (10). L'element de soutenement peut accepter differentes formes. La liaison rigide avec la corniere entraine essentiellement une resistance globale depassant la resistance propre provoquee par la corniere et l'element de soutenement.
