<p>This invention relates to improvements in retaining wall structures (10) derived from a plurality of like structural blocks (12) stacked end-to-end one upon the other in generally horizontally axially extending courses in overlapped wall defining relation. The blocks (12) have a body portion with an axis terminating in opposed end surfaces (20, 22), and are bounded by front (24) and rear (26) facings and by generally parallel upper (16) and lower (18) surfaces, with the upper (16) and lower (18) surfaces including therewithin respective opposed axially extending recess formations (28, 30). More particularly, this invention relates to a connector (14) for selectively positioning and interlocking against transverse displacement the blocks (12) used in constructing the retaining wall structure (10). The connector (14) includes a base portion (36) of a configuration for the mating reception within one of the opposed recess formations (28, 30) of the blocks (12) in at least one of three orientations, and a projection portion (50) upstanding from the base portion (36) of a configuration for the mating reception within the other of the opposed recess formations (28, 30) of the blocks (12), likewise in at least one of three orientations. The projection portion (50) and the base portion (36) of the connector (14) are offset a selected extent so as to establish together with respective stacked blocks (12) of the retaining wall structure (10) at least three interlocked and overlapped wall defining dispositions.</p> |
