PROBLEM TO BE SOLVED: To provide a uniform arrangement jig of a hollow column in which plural reinforcement rod-like members can be arranged uniformly in the circular direction and a cable member of an electric wire, a signal line, etc. is allowed to pass easily and certainly through a cavity of the inside of the hollow column.SOLUTION: A uniform arrangement jig 20 of a hollow column is disposed in a cavity of a hollow column 1 which is erected on the ground with the lower part embedded under the ground, and arranges reinforcement rod-like members which are aramid rods 13 and steel wires 14 for example uniformly in the circular direction. The uniform arrangement jig 20 includes a ring-shaped enclosure part 21, insertion parts (22, 23) which are provided at the inside of the enclosure part 21 and guide and hold reinforcement rod-like members (13, 14), and an opening part 20P which allows a flexible duct line material 11 for guiding a cable member S to pass in the area formed by the enclosure part 21 and the insertion parts (22, 23). |
