Claim Text:
1. A construction block, comprising: transversely disposed first and second end walls disposed in parallel, longitudinally spaced apart relation to one another; longitudinally disposed first and second sidewalls disposed in parallel, transversely spaced apart relation to one another, the first and second sidewalls having a common length equal to the spacing between the first and second end walls and being formed integrally with the first and second end walls; longitudinally disposed top and bottom walls disposed in parallel relation to one another and spaced apart from one another by a predetermined distance, the predetermined distance determined by a common height of the first and second sidewalls, the top and bottom walls being formed integrally with the first and second sidewalls, and the top and bottom walls being formed integrally with the first and second end walls; the first end wall being recessed relative to a first end of the block; the second end wall being protruded relative to a second end of the block, the recess of the first end wall adapted to receive the protrusion of the second end wall therein, forming a mortarless vertical joint when a first block is disposed in an end-to-end relation to a second block; the bottom wall being recessed relative to a bottom edge of the sidewalls; a longitudinally-extending protrusion formed in said top wall, the top wall protrusion having a width less than a width of the block; a substantially semi-circular longitudinally-extending channel formed in the top wall protrusion, the longitudinally-extending channel positioned offset from a longitudinal axis of symmetry of the block and adapted to receive a rebar therein, and a pair of parallel, longitudinally-extending ledges formed in each block by the top wall protrusion, the ledges adapted to receive bottom edges of the first and second sidewalls forming a mortarless horizontal joint when a first block is disposed in overlying relation to a second block.
