PROBLEM TO BE SOLVED: To set a construction cost and an execution time in the same extent as the friction joint of a high strength bolt, and to inhibit the generation of noises more than the friction joint of the high strength bolt without deteriorating a landscape in the joining of the high strength bolt for a steel box girder. SOLUTION: The joining sections of upper and lower flange sections, which are not conspicuous, are formed in the friction joints of the high strength bolts as seen in conventional devices, and the joining sections of web plate sections, which are conspicuous and are at issue on the landscape, are joined by the high strength bolts on the girder internal-surface side, and are not viewable on the external surface sides. |
