PURPOSE: To enhance workability by replacing steel wires or reinforcing bars whose projected pats are projected to a form by press work as a part of wire meshed main steel wires or installing them as setup reinforcements of grid-like reinforcements in parallel to reinforcing bars.
CONSTITUTION: At least one steel wire 2 out of crosswise wire meshed steel wires 2 is partially replaced with a press-worked steel wire 2 having a projected part 3. Then, in the case of floor slab grid-like reinforcements with a spacer, for example, a press-worked reinforcing bar 1B is installed as a setup reinforcing bar along a main bar 5A or a distribution reinforcing bar 5B. Then, during this work, the reinforcing bar is used to maintain strength of concrete, for example, to reinforce tensile strength or shearing strength. It is necessary, therefore, to avoid the replacement of a part of the reinforcing bars, such as wire meshes with the steel wire 1B. During the laying out work, the tip of the projected part 3 is loaded on a form, such as a deck plate 4, thereby securing a covering thickness of the concrete. This construction makes it possible to eliminate all mounting work of spacers or the like, and what is more, to prevent the spacers from falling out or turning.
