PURPOSE: A flange assembly for connecting a connection pipe of a concrete structure is provided to guarantee stable coupling and to maximize watertightness by absorbing bending and tensile force because flanges are symmetrically installed in both sides. CONSTITUTION: A flange assembly for connecting a connection pipe of a concrete structure(100) comprises coupling parts, a boss(110), and a pair of flanges(120). After the coupling parts are coupled, the outer circumference of connection pipes is enclosed. The section of the boss is attached along the outer circumference of the connection pipes. The pair of flanges is extended to the outside of the boss. In order to improve watertightness by increasing adhesion strength between the boss and the connection pipes and coupling force with a concrete structure when the boss is installed in the connection pipes, the pair of flanges is curved to both sides facing each other. The pair of flanges is separated from the upper end of a center part of the boss to the lower part. |
