PURPOSE: A flange connecting assembly for a corrugated steel pipe is provided to separate a first and a second fixing bracket from a first and a second coupling flange capable of rotating against the peripheral direction of a steel pipe, thereby easily aligning fastening holes for fastening the first and the second coupling flanges. CONSTITUTION: A flange connecting assembly for a corrugated steel pipe includes a first fixing bracket(100a), a second fixing bracket(100b), a gasket, a first coupling flange(200a), a second coupling flange(200b), and a fastening unit(300). The first and the second fixing brackets are installed on the outer periphery of the end portions of corrugated steel pipes facing each other. The gasket is interposed between the first and the second fixing brackets. The first and the second coupling flanges are respectively and radially formed outside the first and the second fixing bracket, and face each other. The fastening unit closely attaches the first and the second coupling flanges to each other. The first and the second coupling flanges are separated from the first and the second fixing brackets. The first and the second coupling flanges respectively have coupling through-holes of which the diameters are larger than the diameters of the corrugated steel pipes, so that the first and the second coupling flanges can rotate in the peripheral direction of the corrugated steel pipe. |
