ABSTRACT A fixture is disclosed for precisely locating the vertical reinforcing steel bars in a hollow block wall at the exact positions specified by the design engineer. The fixture comprises one or more steel wires forming a horizontal supporting structure that is adapted to be laid on the top surface of the blocks at various levels as the blocks are being laid. The horizontal supporting structure is a generally square structure having a circular ring attached to the inside of each corner and downwardly projecting legs that extend down into the cavities of the hollow blocks and engage the inner surfaces thereof to locate the structure with respect to the blocks. The rings of the structures at different levels are positioned in vertical alignment with respect to one another, and the vertical bars are lowered into the block cavities from the top of the wall, with the bar being inserted through each of the rings, in turn, at the different levels. After the steel bars have been placed, the cavities are filled with cement grout, which embeds the bars.
