ABSTRACT:
A compound block kit of edge-toothed concrete blocks, in which the compound blocks are coordinated relative to their cross-sectional shape and size and have cobblestone blocks to palisade blocks of various heights. The cobblestone compound blocks and palisade compound blocks are provided with edge-teeth extending around the entire block circumference and are engageable with one another. The similar edge-teeth prevent a relative shifting of the blocks. The identical cross-sectional shapes and sizes permits any desired insertion and exchange of compound blocks at any desired position.
