Abstract
Abstract A wall structure and a block for forming same in which the block is generally rectangular and divided along its length into four substantially equal parts with a vertical hole centrally positioned through each of the four parts. Each of the four parts also has an alignment groove such that when two overlying blocks in adjacent courses of blocks overlie by any number of onefourths of the length of a block, at least some of the alignment grooves and vertical holes will be vertically aligned. Expandable aligning rods are provided to be received within the aligned aligning grooves and to extend through several courses of blocks to assure vertical alignment of a plurality of blocks vertically disposed, and long or short expandable sleeves are inserted into the aligned vertical holes and filled with mortar to lock the blocks together and rigidify the wall structure.
