An interlocking lock system for mortarless wall or other structure assembly in which a plurality of blocks are laid up in courses in a staggered relationship. Only two different block configurations are required, the first, or long, blocks having a length at least twice the block height and the second, or short, blocks having a length up to half the length of the first blocks. Each of the blocks has a pair of upright sidewalls having flat top and bottom surfaces and generally parallel outermost side surfaces and has at least two spaced transverse walls. Protrusions on the inner surfaces of the sidewalls extend from a base generally coplanar with the block bottom surface to a tip extending above the block top surface and configured so that the tips and bases interlock when the blocks are laid up in staggered courses. Further interlock arrangements are provided so that the long blocks will interlock when positioned either parallel along walls or perpendicular at corners. A tongue and groove interlock configuration is provided at the ends of the blocks so that the ends interlock. |
