Claims5
A box-type of masonry block comprising:
- a substantially rectangular concrete block body having side walls which define a hollow interior portion and define upper and lower peripheral surfaces of said block body;
- an upper flange element formed along said upper peripheral surface of said block body;
- a lower flange element formed along said lower peripheral surface of said block body for engaging a corresponding upper flange element of a downwardly-adjacent block body;
- upper engaging means formed along at least a portion of said upper flange element;
- lower engaging means formed along at least a portion of said lower flange element for engaging a corresponding first upper engaging means of a downwardly-adjacent block;
- upper rib means formed peripherally about an uppermost portion of the walls of said hollow interior portion, said upper rib means being wave-shaped such that the uppermost surface thereof undulates along at least a portion of the length thereof, about the periphery of said hollow interior portion;
- lower rib means formed peripherally about a lowermost portion of the walls of said hollow interior portion, said lower rib means being wave-shaped such that the lowermost surface thereof undulates along at least a portion of the length thereof, about the periphery of said hollow interior portion;
- and
- upper and lower annular grooves surrounding and disposed outwardly relative to said upper and lower rib means, respectively.
