PROBLEM TO BE SOLVED: To provide a C-shaped steel fixing bolt utilizable as means for fixing C-shaped steel on a C-shaped steel pedestal part in the direction for supporting both-side lip parts of the C-shaped steel on the C-shaped steel pedestal part.SOLUTION: A rotation limiting plate 3 is relatively non-rotatably installed on a bolt 2 in a central position in a length direction of the plate between a head part 6 of the bolt 2 and a presser metal fitting 4, and after inserting the presser metal fitting 4 and the rotation limiting plate 3 into the inside of C-shaped steel 22 from between both-side lip parts 23a and 23b of the C-shaped steel 22, when deflecting the presser metal fitting 4 in the direction for both ends thereof to press down both-side lip parts 23a and 23b of the C-shaped steel 22 by rotating the bolt 2 in the fastening direction of a nut 25 to the bolt 2, both-ends of the rotation limiting plate 3 abut on an inner surface of parallel both-side plates 24a and 24b of the C-shaped steel 22, and limit rotation of the bolt 2 more than that. |
