Abstract:
A wall structure comprising a foundation having a substantially planar and horizontal upper surface, a metal strip attached to and extending upwardly from the upper surface of said foundation, a plurality of blocks arranged in a first course, each of said blocks having a top, a bottom, two opposed ends and two opposed major surfaces, said metal strip being received in a groove in the bottom of each of said blocks of the first course, and said blocks being so shaped that each of the opposed ends of interior ones thereof is in close fitting, abutting relationship with an end of an adjacent one of said blocks, and each of the major surfaces thereof is substantially coplanar with the corresponding major surface of the others of said blocks in the first course, said metal strip being effective to lock said blocks of the first course against lateral movement relative thereto, a second metal strip received in a groove in the top of each of said blocks of the first course, and a plurality of blocks arranged in a second course, each of said blocks in the second course having a top, a bottom, two opposed ends and two opposed major surfaces, said second metal strip being received in a groove in the bottom of each of said blocks of the second course, and said blocks of the second course being so shaped that each of the opposed ends of interior ones thereof is in close fitting, abutting relationship with an end of an adjacent one of said blocks of the second course, and each of the major surfaces thereof is substantially coplanar with the corresponding major surface of the others of said blocks in the second course and with the corresponding major surfaces of said blocks of the first course, said second metal strip being effective to lock said blocks of the second course against lateral movement relative thereto and relative to said blocks of the first course, and at least one metal strip which is received in a laterally extending groove in the top of a first block in the first course and in a groove in the bottom of a second block in the second course, and is effective to prevent sliding movement of said first and second blocks relative to one another in a direction longitudinal of the grooves in the tops and bottoms of said first and second blocks.
