<P>PROBLEM TO BE SOLVED: To provided a flange joint having strength high enough to withstand high pressure, and a method of manufacturing the same. <P>SOLUTION: A first reinforcing member 33 is positioned along a peripheral surface of a columnar part 21c of a female mold 21, and a cut line-formed part is bent and positioned along a flat surface 21a of the female mold 21. Thus, the cut line-formed part of the first reinforcing member 33 assumes a shape which comprises triangular gap parts G formed between a plurality of rectangular flange part reinforcing parts 33b and adjacent rectangular flange part reinforcing parts 33b. Subsequently, second reinforcing members 34A and 34B, which assume a trapezoidal shape comprising the flange part reinforcing parts 33b and the triangular gap parts G on both sides thereof, are arranged in such a manner that triangular parts 34b of the second reinforcing members 34A and 34B adjacent to each other overlap each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
