Abstract:
1. A block wall building unit for constructing a block wall, comprising: a monolithic block having a generally planar front face, a first edge, a second edge, a first end, a second end, and a back face; at least one male interlocking element integral with and extending from said back face, each of said male interlocking elements including a tapering conical leg portion which projects and extends outwardly into an integral ankle portion, which, in turn, expands into a shoe portion that includes a planar sole defined by an outboard upper portion and an inboard upper portion, said upper portions being generally normal to said planar sole and adjoining said sole in outboard and inboard edges, a generally flat toe, a heel, a vamp, and a topline; a female interlocking element integrally formed as a female concavity in each of said leg and ankle portions of said male interlocking elements, said female interlocking elements including a sole side, a medial upper side, a lateral upper side; wherein when a first of said monolithic blocks is properly aligned with a second of said monolithic blocks, identical to said first monolithic block, each of said female interlocking elements on one of said monolithic blocks conforms precisely to a corresponding complementary male interlocking element on the second of said monolithic blocks because said heel portion of said male interlocking element slidingly inserts into said female concavity to form upper and lower interlocked blocks, the combination of said first and second monolithic blocks forming a portion of a course in a wall.
