The description relates to an artificial stone (1) for stabilising traffic areas in the open. In order to form broad seams between stones laid beside one another, this stone has one-piece identical spacer projections (5, 6) on its side surfaces (3, 4), the superimposed free end surfaces of the spacer projections (5, 6) have a tooth (10) and a recessed bearing surface (11) side by side for engaging with the adjacent stone (1). The sequence of tooth (10) and recess (11) for all spacer projections (5, 6) around the stone is identical; in a stone, the effective length of the individual side surfaces parallel to the laying plane is a single or whole-number multiple of a shortest effective length; each side surface section of the shortest effective length (3, 4) has a spacer projection (5, 6) and the median axis (12) of all spacer projections (5, 6) lies at the centre of the relevant side surface section. Here, the bearing surfaces are designed as a tooth gap (11) corresponding to the size of the tooth (10) and surrounding it on both sides to the laying plane and the relevant side surface, the flanges of the tooth (10) pointing in said direction on the one hand and the tooth gap (11) on the other form an angle of at least 90 DEG and the bisecting line (42, 43) of said angle is substantially parallel to the normal to the relevant side surface. |
