A composite masonry block having a front surface and a back surface which are adjoined by first and second side surfaces, as well as a top surface and a bottom surface each lying adjacent the front, back, and first and second side surfaces. Each of the side surfaces has an inset spanning from the block top surface to the block bottom surface. The block top surface has one or more protrusions positioned adjacent the first and second insets on the block top surface. The blocks have back legs which are directed outwardly from the blocks back surface. The block back legs may extend in a plane parallel to the block front surface or extend forwardly toward the blocks front surface. In use, the blocks may be stacked to provide an interlocking structure wherein the protrusions of one block interfit within the insets of another block. 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 is also explained.
A masonry block comprising a front surface, a back surface, a top surface and bottom surface, and first and second sides, said first side having a first inset wherein said first inset extends from said block top surface to said block bottom surface, said second side having a second inset wherein said inset extends from said block top surface to said block bottom surface, said block comprising, a protrusion on one of said top or bottom surfaces, said protrusion configured to mate with the inset of one or more adjacently positioned blocks, said protrusion comprising first and second side surfaces wherein said first side surface is angled to interlock with one or more blocks positioned adjacent said composite masonry block, and said second protrusion side surface is angled to facilitate manufacture.
A masonry block comprising a front surface and a back surface, a top surface and bottom surface, and first and second sides, said first side having a first inset wherein said first inset spans from said block top surface to said block bottom surface, a protrusion on one of said block top or bottom surfaces, and, first and second legs, said first leg extending from said block first side and said second leg extending from said block second side, said protrusion comprising first and second side surfaces wherein first side surface is angled to interlock with one or more blocks positioned adjacent said composite masonry block, and said second protrusion side surface is angled to facilitate manufacture.
A retaining structure, said retaining structure comprising one or more courses, each of said courses comprising one or more masonry blocks, each of said blocks comprising a front surface and a back surface, a top surface and bottom surface, and first and second sides, said first side having a first inset wherein said first inset extends from said block top surface to said block bottom surface, said second side having a second inset, wherein said inset extends from said block top surface to said block bottom surface, a protrusion on one of said block top or bottom surfaces, wherein said block protrusion is configured to mate with the inset of one or more adjacently positioned blocks, said protrusion comprising first and second side surfaces wherein said first side surface is angled to interlock with one or more blocks positioned adjacent said composite masonry block, and said second protrusion side surface angled to facilitate manufacture.
