| 摘要 |
<p>The invention is a composite masonry block having a front surface (12) and a back surface (18) which are adjoined by first and second side surfaces (14, 16), as well as a top surface (10) and a bottom surface (8) each lying adjacent the front (12), back (18), and first and second side (14, 16) surfaces. Each of the side surfaces (14, 16) has an inset (22A, 22B) spanning from the block top surface (10) to the block bottom surface (8). The block top surface (10) has one or more protrusions (26) positioned adjacent the first and second insets (22A, 22B) on the block top surface (10). The blocks of the invention comprise back legs (24A, 24B) which are directed outwardly from the blocks back surface (18). The block back legs (24A, 24B) may extend in a plane parallel to the block front surface (12) or extend forwardly toward the blocks front surface (12). In use, the blocks may be stacked to provide an interlocking structure wherein the protrusions (26) of one block interfit within the insets (22A, 22B) of another block. The invention also comprises a method of block molding and a mold assembly which may be used to make a block which may be stackable to form structures of varying setback.</p> |
