Construction set of shaped concrete blocks and device for producing the same

摘要

Known construction sets consist of shaped blocks (10), so-called shovel blocks, which have a groove only in the side walls (12, 13). Only shaped blocks (10) lying next to one another within one layer can be positioned by these grooves. The construction set according to the invention consists of shaped blocks (10) in which recesses are arranged in both the bottom wall (14) and the side walls (12, 13), coupling pieces (25) entering with a sectional area (26) into one of the recesses (grooves 22, 23) of the side walls (12, 13) and with another sectional area (27) into one of the recesses (21) of the bottom wall (14) of the shaped block above it. Shaped blocks of this type are used for constructing retaining walls in which plants can be grown. <IMAGE>
