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