Abstract

Abstract Seen in side elevation, the block has at one side at least a flat curved or trapezium-shaped protrusion (1), while in the opposite side is a mating curved or trapezium-shaped recess (2). The protrusion can extend for at least 80% of the respective block side length, and can be chamfered at its ends. It can protrude for 5 to 7mm. It and the recess can extend for 50 to 70% of the block height, and distance-pieces (4) can be formed on the block below them. Other distance-pieces, protruding for 2 to 3mm. can be formed above them.
