Abstract

L'invention concerne une structure spatiale qui réduit le nombre d'éléments formant des membrures longitudinales et transversales ou des éléments diagonales et qui simplifient le mode d'assemblage ou analogue. Les membrures longitudinales et transversales (2a, 2b; 3a, 3b) situées dans des réseaux supérieurs et inférieurs (2, 3) sont formées par disposition en réseau d'éléments de barre de longue taille (8) possédant une longueur équivalente au double de la distance d'intersection et par connexion des sections de connexion (8a, 8a) aux extrémités des éléments de barre de longue taille (8, 8) traversant une section de connexion centrale (8b) en direction de celle-là. Les éléments diagonaux (4a, 4b) interconnectent les intersections (5, 6) des membrures au niveau de réseaux (2, 3), lesquels sont formés par disposition en réseau d'éléments de barre pliés en forme de V (10) et par connexion des sections de connexion (10a, 10a) au niveau des extrémités des éléments de barre pliés (10, 10) traversant la section de connexion (10b) au milieu de chaque élément de barre plié (10) vers la section de connexion (10b).
