PROBLEM TO BE SOLVED: To provide a device for correcting a flange buckling capable of efficiently and accurately correcting a flange buckling generated when a channel shape cross sectional steel stock 1 such as a vertical rib provided for reinforcement in the lower surface of steel slab of the bridge is heat-treated by a burn bending method or the like.;SOLUTION: The main body 11 of the device whose flat surface shape is composed of a square frame shape is provided with a hydraulic cylinder 15 in the fixing portion 19 protruded in the bottom portion of one side 17 of the square and from the outer side, buckling portion 7 is pressed. A pair of claws 25 are formed in the bottom of each tip end of the two sides 23 extending from one side 17 where the hydraulic cylinder is provided and the pair of claws 25 have a U shape cross sectional surface which holds the flange 5.;COPYRIGHT: (C)2003,JPO
