BAR ARRANGEMENT STRUCTURE AND BAR ARRANGEMENT METHOD OF REINFORCED CONCRETE STRUCTURE

PROBLEM TO BE SOLVED: To provide a technique for suitably suppressing buckling of axial reinforcing bars of a reinforced concrete structure while making the cost less than before.SOLUTION: There is provided a bar arrangement structure of a bridge pier body 5 having axial reinforcing bars 51 arranged outside an outer periphery of a member in an axial direction of the member, and belt reinforcing bars 52 wound around an outer peripheral side of the axial reinforcing bars 51, the bar arrangement structure including fixation parts 55 inserted from gaps between the belt reinforcing bars 52 halfway into internal concrete enclosed with one belt reinforcing bar 52, buckling suppression fixation reinforcing bars 54 comprising lock parts 56 in a predetermined lock shape which are provided to base end sides of the fixation parts 55 and locked to outer side faces of the belt reinforcing bars 52, and attitude holding members 57 which are bound to tip sides of fixation parts 55 of the respective buckling suppression fixation reinforcing bars 54 to hold the fixation parts 55 in an attitude along member axial orthogonal sections.
