Cornice for the building and construction made up of two parts (d) and (f), the part (a) forming chaînage.ce system has the purpose of keeping the stone of the apparent size, while reducing the volume and the cost of that - ci. The product is composed of a part (d) in the cement cast, one end of which is in overhang with respect to the bearing wall (i) on which is bonded to the part (f) as a stone and interlocked by (m) in the part (l) to the dovetail. The shape of the part (f), it is possible between (d) and (f) and the bearing wall (i) to form the housing (h) in which the coating (j) rises and thus avoids the micro - cracks and provides a perfect seal, the part (f) at the sides (e) and (g) which are parallel, thus allowing the production of a single pass, because of this shape of the part (c) forming a bevel with respect to the traditional form of a ledge thus avoids to receive a load as a less fragile for transporting and laying.
