Patent

CA 2387977

The invention concerns a reinforcement (1) comprising: two parallel walls formed with braces arranged along two orthogonal directions, said walls being suitably maintained spaced apart by tie rods (4, 5), said structure further comprising on at least one of its formwork surfaces a permeable structure retaining the aggregate and allowing the cast concrete excess water to escape. Said reinforcement is characterised in that one of the two parallel walls consists of two mutually independent grates; one (2A) of the two independent grates (2A, 2B) is associated with the other wall (3) by a first set of tie rods (4) and the other gate (2b) of said wall is likewise associated with the other wall (3) by a second set of tie rods (5) independent of those of the first set such that when the grates are displaced in opposite directions and along an axis parallel to the plane of the grates, the spacing between the walls is modified.

L'invention se rapporte à une amature (1) comprenant deux parois parallèles formées de ferrures disposées selon deux directions orthogonales, ces parois étant maintenues à l'écartement requis par des entretoises (4, 5), cette structure présentant en outre sur au moins l'une des ses faces coffrantes une structure perméable retenant les agrégats et laissant s'échapper l'eau excédentaire du béton coulé. Cette armature est caractérisée en ce que: l'une des deux parois parallèles est constituée de deux grilles indépendantes l'une de l'autre; l'une (2A) des deux grilles (2A, 2B) indépendantes est associée à l'autre paroi (3) par un premier ensemble d'entretoises (4) et l'autre grille (2B) de cette paroi est associée également à l'autre paroi (3) par un deuxième ensemble d'entretoises (5) indépendantes de celles (4) du premier ensemble de sorte qu'en déplaçant les grilles en sens opposé et selon un axe parallèle au plan des grilles, on modifie l'écartement des parois.
