Concrete paving-stone system has single paving stones with a cube-shaped form like a grid with low-lying perpendicular teeth on side surfaces and grooves running parallel to the width of the paving stones

摘要

First wide (1a) and second narrow (1b) large-sized paving stones have the same length (2) but two different widths (3). A small-sized paving stone adds to a system with its length having the width of the first wide large-sized paving stone and its width having the width of the second narrower large-sized paving stone. A grid-marking groove on a paving-stone underside is integrated on each long-side (5) section of a grid (4) fastened by a tooth's (7) length dimension or by an intermediate space (8) between teeth or vice versa.
