ABSTRACT:
1. Paving stone set and process and device for the manufacture thereof.
2.1. In the case of lawn-paving blocks formed from paving stones (10) spaced at a considerable distance apart, these are joined together, against relative displacements, by a holding grid (11) embedded in the paving stones (10) and comprising tension-resistant strands. The said holding grid allows the transfer of traction forces and hence the reciprocal safeguarding of the paving stones (10) within a paving stone set held together by the holding grid (11).
2.2. The manufacture of the paving stone sets is effected in a concrete stone mold which is conventional in its principle. A flask (19) disposed on a molding plate (28) and a drawing sheet (29) is divided in the horizontal plane (33), creating a top part-flask (34) and a bottom part-flask (35). The holding grid (11) is clamped between the two part-flasks during pouring of the concrete. Following the completion of a paving stone set, the bottom part-flask (35) is withdrawn from the concrete stone mold. Demolding can now be carried out in the usual manner.
