Concrete-molded stone and ready-to-assemble construction made of molded stones

Abstract

An essentially quadrate paving stone having a corresponding base block ( 21 ) is provided on all four side surfaces ( 25, 26 ) with flange-like, upright spacers ( 22 ) which are spaced apart from each other at intervals corresponding approximately to the width of the spacers, making it possible for them to make an interlocking connection with adjacent shaped paving stones of the same type. Furthermore, the bottom side ( 24 ) of the paving stone features a number of transverse, gutter-like depressions resulting in the formation of ribs between these depressions. This creates an additional dentification, or anchoring, in the bed surface of the installed paving stones.

A ground cover laid on a pavement bed, comprising paving stones made of concrete each having a flat top side, a bottom side, four upright side sides, spacers arranged continuously around the four upright side sides in a uniform grid pattern, and shifting prevention devices on the four sides and the bottom side, wherein: 
 a) the spacers of one of the stones are arranged to engage in an offset manner with the spacers of a neighboring stone;    b) the spacers extend along the upright side sides from the bottom side to slightly below the top side, and, in the transition of the spacers to the side walls at a point slightly below the top side, the top sides of the spacers are beveled and provided with a chamfer;    c) the spacers have a flange-shaped, trapezoidal cross-section and have a constant width and depth and are arranged in a regular grid pattern;    d) the spacers of adjacent side sides are respectively offset to one another, namely in gaps, with the spacer of one of the side sides immediately bordering the adjacent one of the side sides;    e) the shifting prevention devices on the bottom side are a plurality of depressions, within the stone, that interlock with the pavement bed and extend continuously from one of the upright side sides to another of the upright side sides;    f) the bottom side has projections between the depressions extending across the entire bottom side and the depressions are arranged parallel to one another and are spaced at equal distances from one another by a space that corresponds approximately to one grid unit; and    g) the stones are arranged on the pavement bed in a continuously interlocked manner such that one of the four side sides of one of the stones abuts one of the four side sides of a neighboring stone along the side wall and a continuous paving surface is formed between neighboring stones,    wherein the ground cover is resistant to horizontal force components resulting from traffic loads.
