Abstract
The invention relates to horizontally and vertically linked paving stones (10). According to the invention, projections (18) and recesses (19) are provided in the area of the bottom part (16) of the paving stones (10) used for a paved surface in order to link said paving stones horizontally and vertically. These projections and recesses engage with each other with a positive fit so as to interlock adjacent stones in a horizontal and vertical direction. The paving stones (10) are characterised in that the width of the joints (32) formed between adjacent paving stones (10) increases in a downward direction so as to form a gap which diverges downwards. This means that the material used for filling the joints can be introduced efficiently and reliably as far as the underside.

A paving stone (10), made of concrete, for producing a paved surface formed by a plurality of paving stones (10) which are laid next to one another to form, between adjacent paving stones (10), longitudinal and transverse joints (32, 33) which are filled with joint filling material, wherein:
- the paving stone (10) comprises an upper stone part (15), which is rectangular or square in a horizontal projection thereof, and a lower stone part (16) having a central projection (18), a depression (19) and two corner projections (25);
- the lower stone part (16) projects at a first longitudinal side (11) of the paving stone to from the central projection (18) having a horizontal projection which extends partially beyond an outer contour of the upper stone part (15);
- between the corner projections (25), the lower stone part (16) is partially recessed to form the depression (19) in a horizontal projection with respect to the outer contour of the upper stone part (15);
- the central projection (18) and the depression (19) have a trapezoid-shaped horizontal projection and have corresponding dimensions;
- the two corner projections (25) are formed in their common horizontal projection to correspond in shape and dimension to the depression (19);
- and
- the paving stone has two transverse sides (13, 14) each of which extends essentially as a smooth, vertical and continuous plane over said lower stone part (15) and said upper stone part (16).
A set of paving stones made of concrete for producing paved surfaces, with a curved set (47) of curved stones (46) of a wedge-shaped form, wherein:
- the curved stones (46) comprise an upper stone part (15) and a lower stone part (16) having a first projection (18), a depression (19) and two comer projections (25);
- the lower stone part (16) projects at a longitudinal side (11) to form the first projection (18) whose horizontal projection extends partially beyond an outer contour of the upper stone part (15);
- at a longitudinal side (12) opposite the first projection (18), the lower stone part (16) partially projects to form two comer projections (25) in its horizontal projection with respect to the outer contour of the upper stone part (15);
- between the comer projections (25), the lower stone part (16) is partially recessed to form a depression (19) in its horizontal projection with respect to the outer contour of the upper stone part (15);
- the first projection (18) and the depression (19) have a trapezoid-shaped horizontal projection and are formed with corresponding dimensions;
- the two corner projections (25) are formed in their common horizontal projection to correspond to the depression (19);
- two upright transverse sides (13, 14) of the curved stone (46) run essentially continuously over the lower stone part (15) and the upper stone part (16);
- opposite longitudinal sides (11, 12) of the curved stone (46) converge toward each other;
- and
- a plurality of curved sets (47), laid next to one another, form a paved surface with a curved layout, wherein the first projections (18) and the depressions (19) of adjacent curved stones (46) of the curved sets lying next to each other correspond to one another for being laid with a horizontal and vertical interlocking composition.
Device for producing paving stones from concrete, to be specific curved stones (46) with undercuts for vertically linking adjacent paving stones or curved stones (46), in a concrete mould which rests on an underlay which can be pulled away to the side in a horizontal plane, to be specific on a pulling plate (49), on the upper side of which ridges are arranged for limiting side surfaces of the paving stones, characterized in that the moulding ridges (51) are formed such that they diverge in the pulling direction of the pulling plate (49), with an increasing transverse dimension or width.
