END-WORKED REINFORCEMENT, REINFORCEMENT ARRANGEMENT METHOD USING THE SAME, AND END WORKING METHOD FOR REINFORCEMENT

PROBLEM TO BE SOLVED: To efficiently perform reinforced concrete work by shortening the lap joint length and anchored length of reinforcements without lowering adhesion between the reinforcements and concrete. SOLUTION: An end-worked reinforcement 1 in this embodiment is formed with flat parts 3 by pressing the tip of ordinary round steel 2 which is a reinforcement used as a workpiece, in an orthogonal direction (arrow marks in the figure) to the material axis direction (A in the figure) of the reinforcement by cold working. The flat parts 3 are formed in the plural number and sequentially formed adjoining from the tip of the ordinary round steel 2, and the pressing directions (the arrow marks in the figure) are alternately orthogonal along the material axis direction (A in the figure).
