Abstract
A reinforcement includes two parallel walls formed with braces arranged along two orthogonal directions, the walls being spaced apart by tie rods. The structure further includes on at least one of its formwork surfaces a permeable structure for retaining aggregate and allowing excess water of cast concrete to escape. According to the invention, at least one of the parallel walls includes two mutually independent grates, one the grates being associated with the other wall by a first set of tie rods, and the other of the grates being associated with the other wall by a second set of tie rods, independent of the first set. When the grates are displaced in opposite directions along an axis parallel to the plane of the grates, the spacing between the walls is modified.

Reinforcement for a concrete wall comprising first and second parallel walls, each formed of braces arranged along two orthogonal directions, said parallel walls being spaced apart by tie rods, said reinforcement further comprising on at least one formwork surface a permeable structure for retaining aggregate and allowing excess water to escape from cast concrete,
- said first wall being formed of two independent grates, one of said independent grates being associated with the second wall by a first set of tie rods, and the other of said independent grates being associated with the second wall by a second set of tie rods independent from the tie rods of the first set,
- said grates being independently movable in opposite directions along an axis parallel to the plane of the grates, whereby spacing between the first and second walls may be modified.
