<p>The present invention is directed toward a concrete masonry block (10) used to construct masonry walls in a building. The concrete masonry block (10) has an external plate or plates (24, 26) that are anchored through the concrete masonry block (10). The external plate or plates (24, 26) may cover a small or substantial portion of the external surfaces of the concrete masonry block (10). The casting machine that casts the concrete masonry block receives the external plate or plates and anchors into the mold prior to casting the concrete masonry block. During casting, concrete is formed around the anchors, but inside the external plates. Thereafter, walls are built using some of the cured concrete masonry blocks with external plates at preselected locations to anchor things to the wall by attaching to the plates. Such masonry blocks are particularly useful in constructing buildings that must be structurally strong, functional, and easy to maintain.</p> |
