Abstract
Abstract A construction block has interior, tapered wall cells. The tapering of the walls provides precisely maintained interior geometry for a long life time of use of the molds employed in manufacture of such block. Insertable cores of precise dimension to fit intimately within such cells and to come into intermittent contact with similar cells in adjacent blocks in a running course of said blocks and with similar cells in adjacent blocks in adjacent courses of said cells provide for the erection of a standing wall from drystacked running courses of such block wherein such running courses are self-aligned and self-leveling. The intimate contact of the insertable cores permit the formation of open-gapped interlocks between blocks and running courses, which open-gapped interlocks are converted to closed-gapped interlocks when a wall erected of such running courses is coated with a surface bonding cement.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
184 words
A method for erecting a drystacked block wall which is self-leveling and self-aligning comprising the steps of A. providing a sufficient quantity of tapered interior wall, hollow celled block for the wall to be erected; B. providing precision dimensioned, tapered wall, interlocking cell cores for insertion with intimate tapered wall contact within selected tapered interior wall hollow cells of the blocks provided in step A; C. inserting a cell core in a selected tapered interior wall hollow cell of each block of a first dry stacked running course of block in the wall to be erected for interlocking alignment in a cell core inserted in a selected tapered interior wall hollow cell of each block in a second drystacked running course of block in said wall to be erected; and D. utilizing the intimate tapered wall contact and the precision dimensions and interlocking of said cell cores to maintain the wall to be erected in vertical and horizontal alignment by aligning cell core to cell core to control the position of each block relative to each adjacent block in the wall to be erected.
Claim 2
Independent Claim
184 words
A method for erecting a drystacked block wall which is self-leveling and self-aligning comprising the steps of A. providing a sufficient quantity of tapered interior wall, hollow celled block for the wall to be erected; B. providing precision dimensioned, tapered wall, interlocking cell cores for insertion with intimate tapered wall contact within selected tapered interior wall hollow cells of the blocks provided in step A; C. inserting a cell core in a selected tapered interior wall hollow cell of each block of a first dry stacked running course of block in the wall to be erected for interlocking alignment in a cell core inserted in a selected tapered interior wall hollow cell of each block in a second drystacked running course of block in said wall to be erected; and D. utilizing the intimate tapered wall contact and the precision dimensions and interlocking of said cell cores to maintain the wall to be erected in vertical and horizontal alignment by aligning cell core to cell core to control the position of each block relative to each adjacent block in the wall to be erected.
