PURPOSE:To provide reinforcing bars for a reinforced concrete structure, a reinforcing bar cage, and a reinforced concrete structure wherein structure is simplified, manufacture is facilitated, workability of erection of reinforcing bars, and economical efficiency and a reinforcing effect are excellent. CONSTITUTION:A reinforcing bar 1 comprises a columnar steel 2 to perform a role of a main reinforcing bar in a vertical direction, and a loop-form stirrup material 3 with which the columnar steel 2 is surrounded and which crosses the axis of the columnar steel 2. An H-steel having through-holes 4 serving to reduce weight and be formed integrally with concrete 5 is used as the columnar steel 2. A bent loop bar-form reinforcing bar is used as the loop-form stirrup material 3. A number of the reinforcing bars 1 are arranged in juxtaposition such that the loop-form stirrup materials 3 of the adjoining reinforcing bars 1 are overlapped with each other by a given amount. The columnar steel 6 is inserted in the overlapped part to form a reinforcing bar cage. By installing forms 25 and placing the concrete 5, a bridge pier A of reinforced concrete structure where the reinforcing bars 1 are arranged is completed.
