ABSTRACT:
A concrete building block (2) has complementary projections (10) and recesses (12) to cause it to interlock with other blocks (2). A T-shaped channel (16, 26) on the top surface (4) receives an anchor member (32). A projecting end (36) of the member (32) may be secured to an anchor cable (104). The ends of a metal cable (22) are embedded in the block (2) with an eye portion (24) projecting into an increased depth channel portion (20). The lower surface (6) of the block (2) has parallel channels (28) for receiving the tines of a forklift. The channels (16, 28) have breakaway walls (18, 30) at their outer ends, which are not broken away unless the channels (16, 28) are to be used. The walls (18, 30) prevent concrete from flowing out of the channels (16, 28) when reinforcing concrete is poured through vertical openings (14) in the block (2). In molding the block (2), slugs (86) are releasably attached to opposite mold walls to form the openings (14). Notched and three-quarter size blocks (2B, 2C) may be used to form a T-shaped structure. Another modification is an angled block (2A) for forming an angled wall.
