U U-TYPE GIRDER OF LOWER ROUTE BRIDGE FOR DECREASING NOISE AND CONSTRUCTION METHOD FOR THE SAME
When the U-shaped girder of a lower route bridge of the present invention is being made, an acoustic board, which is integrated with a corrugated steel plate, is used. Thus, the present invention can suppress the generation of cracks in an inclined web after concrete is cured and hardened by a corrugated structure of the corrugated steel plate composed with the inclined web. Since the acoustic board, which is integrated with the corrugated steel plate, absorbs noise, the noise of railroad vehicles can be effectively reduced, and the corrugated steel plate, which is made from structural steel, can be prevented from rusting. In addition, when the U-shaped girder of a lower route bridge of the present invention is being made, the acoustic board, which is integrated with the corrugated steel plate, is used as an internal cast, and the quantity of installed casts and manufacturing costs can be reduced. Accordingly, the manufacturing processes of the U-shaped girder of a lower route bridge can be reduced. The U-shaped girder of a lower route bridge of the present invention comprises: a bottom flange; an inclined web; a top flange; a corrugated steel plate; and an acoustic board.
하로교 U형 거더 제작시 파형강판과 일체화된 흡음판을 사용함으로써 경사웨브에 합성된 파형강판의 파형 구조에 의해 콘크리트의 양생 경화 후 경사웨브의 균열 발생을 억제할 수 있고, 파형강판과 일체화된 흡음판이 소음을 흡수함으로써 철도차량의 소음을 효과적으로 저감시킬 수 있고, 강재로 형성되는 파형강판의 부식을 방지할 수 있으며, 또한, 하로교 U형 거더 제작시 파형강판과 일체화된 흡음판이 내측 거푸집으로 활용됨으로써 거푸집의 설치 수량을 감소시켜 제작비용을 저감시킬 수 있고, 이에 따라 하로교 U형 거더의 제작 공정을 단축시킬 수 있는, 소음 저감을 위한 하로교 U형 거더 및 그 시공 방법이 제공된다.
