PROBLEM TO BE SOLVED: To provide a bending correction device for an H beam, capable of correcting bending of the H beam with high quality by preventing web deflection or web twisting, regardless of a web height.SOLUTION: There are provided an external correction roll part 11 which contains an external pressure roll 11a positioned on an outer surface side of one flange 1b1 of H beam 1 that is transported, and an internal correction roll part which contains inner pressure rolls 14a and 15a for pressing down an inner surface of th flange 1b1, being positioned on an inner surface side of one flange 1b1. On inlet side and outlet side of the inner pressure rolls 14a and 15a, a web guide roll is provided which is arranged to face one surface and the other surface of a web 1a of the H beam, to constrain movement of the web in thickness direction. The web guide roll is divided in height direction of the web, and the divided web guide rolls are each independently allowed to contact to or separate from one surface and the other surface of the web 1a of the H beam 1. |
