Noise reduction type U-shaped beam for urban rail transit viaduct
The invention discloses a noise reduction type U-shaped beam for an urban rail transit elevated frame, and relates to the technical field of bridge engineering, the noise reduction type U-shaped beam comprises a U-shaped beam body composed of a bottom plate and side plates symmetrically arranged on the bottom plate, and the bottom plate is rotationally provided with a first noise reduction roller adjacent to the side plates; the multiple first silencing rollers are evenly arranged at intervals in the extending direction of the bottom plate. The noise intensity generated when the vehicle runs on the U-shaped beam can be reduced.
本申请公开了一种用于城市轨道交通高架的降噪型U形梁，涉及桥梁工程的技术领域，包括由底板以及对称设置于所述底板的侧板组成的U形梁，所述底板上转动设置有邻近所述侧板的第一消音辊，所述第一消音辊有多个且沿所述底板延伸方向均匀间隔设置。本申请能够降低车辆行驶于U形梁时产生的噪声强度。
