<P>PROBLEM TO BE SOLVED: To improve workability while securing high reinforcement strength to loads of both compression and tension when reinforcing a steel pipe tower such as a steel power for power transmission. <P>SOLUTION: A pair of end support members 51 and 52 to be attached to a flange part 12 comprises first and second reinforcement flanges 61 and 62, a connection piece 63 for connecting them, a connection piece 64 provided on the second reinforcement flange 62 for connecting a reinforcement material 53, a leg 65 provided on the first reinforcement flange 61 and erected at a position avoiding a bolt nut or the like on the flange part 12, and a long axial bolt 66. Thus, bolts for fastening the flange parts 12 can be replaced and re-fastened one by one, strength decline is minimized, and the need of temporary reinforcement during construction is eliminated. Also, the compression load can be propagated from the leg 65 to the flange part 12a on the inner side, the tension load can be propagated from the long axial bolt 66 to the flange part 12b on the outer side, and both loads can be coped with. <P>COPYRIGHT: (C)2013,JPO&INPIT |
