Abstract

Une structure de renfort comprend plusieurs barres d'acier (10, 40, 60), un arceau en spirale principal (20) entourant les multiples barres en acier (10), dans laquelle des articulations de l'arceau en spirale principal (20) et les barres d'acier (10) sont combinés en toute sécurité, à plusieurs arceaux en spirale secondaires (30), plusieurs barres d'acier (40, 60) étant insérées dans chacun des arceaux en spirale secondaires (30) depuis l'extérieur de l'arceau en spirale principal (20) à l'intérieur de l'arceau en spirale secondaire (30) de telle sorte que des articulations entre l'arceau en spirale principal (20) et l'arceau en spirale secondaire (30) sont formées. Une barre d'acier (10) est enserrée entre l'arceau en spirale principal (20) et les arceaux en spirale secondaires (30) et les articulations de la barre d'acier (10) dans l'arceau en spirale principal (20) et les arceaux en spirale secondaires (30) sont combinés en toute sécurité, via des fils d'acier. L'armature est donc formée par les barres d'acier, l'arceau en spirale principal et les arceaux en spirale secondaires.
