Abstract

The invention relates to a construction kit made of concrete paving stones comprising substantially prismatic stone bodies of a uniform height and upright lateral surfaces. A plurality of stone paving stones (2) arranged in rows and having the same width in addition to the same or different lengths can be placed manually or placed by means of a machine with continuous or offset joints in said joint areas. A plurality of rows of paving stones that are arranged next to each other in a parallel position is used to form a rectangular or square packet that can be placed using a machine. The paving stones (2) have side surfaces (4) which have head pieces (2') that are defined by a wavy line along part of their height and base pieces (2") in sections, comprising domed areas (5) or projections jutting out laterally in relation to the head pieces (2') extending along another part of their height. When the packets are assembled for placement in the vicinity of the end stones that make up a row of paving stones, they form a line of continuous joints or provide substantially winding-shaped joints (7) if so desired by replacing different sized end stones from adjacent packets that have been moved towards each other.
