A hollow concrete element is made up exclusively of circular/cylindrical casing portions, of which at least one is curved convexly and at least a further one is curved concavely. All convex and concave casing portions have the same curvature, with the result that they can be alternately fitted precisely one into the other, a positively locking engagement thus being possible. Two convex portions can be combined with two concave portions in the same way as three convex portions with one concave portion or three concave portions with one convex portion. The novel hollow concrete element is used principally for forming retaining walls, walls, terraces, staircases, seating arrangements and plant arrangements. The novel cast concrete element does not entail any higher production costs, but, owing to its capacity for interconnection, it makes it possible to form novel, visually pleasing combinations, the high stability resulting from the positively locking connection being of great advantage, in particular, in the case of relatively high structures. <IMAGE> |
