ABSTRACT:
In a mortarless interlocking concrete block system, general purpose intersection blocks have parallel grooves formed on their bottom surfaces; but each has mating ridges on the upper surface of its inner end only. The top surface of its corner end portion is flat, to permit an overlying course to fit thereon either at right angles or in linear alignment. The corner end portion has, in each of its two opposite side faces and in its outer end face, parallel vertical grooves matable with tongues on the system's stretcher blocks, to provide interengagement at both left and right corners and T-shaped and crossing-wall intersections. For bond beam courses, a bond beam intersection block with similarly groove corner end faces, has at its inner end portion a closed-bottom channel with saddle-like webs extending between the channel sides, to open through to its corner core and support horizontal reinforcing rods. Consistently formed bond beam blocks and provided, whose tongues may engage any of the grooved corner end faces at wall corners and intersections. Breakout provisions in the corner core inward of these faces make it simple, at any intersection, to lead horizontal reinforcing rods to the cored corner end portions, through which vertical rodding and grouting is provided. By utilizing horizontal reinforcing rods formed at a right angle to extend through the corner block between its two adjacent blocks, the two perpendicular walls may be more securely tied together, to prevent vertical cracking. This furnishes to the easily-constructed mortarless wall block system a sturdy, reinforced concrete grid.
Where desired, blocks made of other material, for example, redwood, may be utilized; also in miniature, the invention may be incorporated in sets of toy blocks, which have exceptional educational value.
