Abstract:
PROBLEM TO BE SOLVED: To provide a flange reinforcement structure and a reinforcement tool for a fire hydrant, capable of being simply attached even in a case where a holding portion of a flange is small, capable of being attached to the flange for reinforcement while efficiently transmitting fastening force to a flange connection portion and enabling downsizing with excellent workability, and capable of preventing looseness or falling after attachment while preventing deformation, to maintain strong holding force.SOLUTION: In a frame-shaped reinforcement tool body 10, provided is a space part into which a flange projection region for connection is interpolated in a lateral direction. In the space part, a presser member 12 configured to press the periphery of a bolt 3 for connecting the flange projection region is provided in a liftable manner. In the reinforcement tool body 10, provided is a fastening bolt 13 configured to press the presser member 12 coaxially.
