Windproof anti-dazzle barrier
The invention discloses a windproof type anti-dazzle barrier, and relates to the technical field of bridge barriers, the windproof type anti-dazzle barrier comprises an anti-collision wall, the top of the anti-collision wall is provided with a plurality of H-shaped steel stand columns, and the H-shaped steel stand columns are arranged at equal intervals in the extending direction of the anti-collision wall; a solid-web sound absorption barrier set and a metal anti-throwing net which are tightly connected are inserted between every two adjacent H-shaped steel stand columns in the height direction, the height of the solid-web sound absorption barrier set ranges from 1350 mm to 1370 mm, the height of the metal anti-throwing net is 1480 mm, and the aperture ratio of the metal anti-throwing net is 70%. By limiting and optimizing the specific structure sizes of the bottom solid-web structure and the upper grid structure, it is effectively ensured that no remarkable vortex shedding is generated when the windproof anti-dazzle barrier is blown by wind, and then the aerodynamic performance of a bridge is effectively improved.
本发明公开了一种防风型防眩屏障，涉及桥梁屏障技术领域，包括防撞墙，所述防撞墙的顶部设置有多个H型钢立柱，多个所述H型钢立柱沿所述防撞墙的延伸方向等间距设置；相邻两个所述H型钢立柱之间沿高度方向插接有紧密相连的实腹式吸声屏障组和金属防抛网，所述实腹式吸声屏障组的高度为1350mm~1370mm，所述金属防抛网的高度为1480mm，所述金属防抛网的开孔率为70%。本发明通过对底部实腹式构造和上部网格构造的具体结构尺寸进行限制与优化，有效确保本发明提供的防风型防眩屏障被风吹拂时不会产生显著的涡脱，进而有效地提高了桥梁的气动性能。
