Cable-stayed bridge steel plate composite beam capable of resisting vortex-induced vibration
The invention discloses a cable-stayed bridge steel plate composite beam capable of resisting vortex-induced vibration, which comprises a bridge deck slab, steel main beams are fixedly arranged at two ends of the bottom of the bridge deck slab, steel cross beams are fixedly arranged between the steel main beams, steel cantilevers are fixedly arranged at the side ends of the steel main beams, and maintenance rails are arranged at the bottom ends of the steel main beams. A stabilizing plate perpendicular to the steel cross beams is fixedly arranged between the middles of the steel cross beams, and flow guiding devices located on the inner sides of the overhauling rails are symmetrically arranged at the bottom ends of the steel cross beams. The flow guiding device is a right-angle triangular prism, the long right-angle side of the section of the flow guiding device is attached to the steel cross beam, the short right-angle side is perpendicular to the steel cross beam, and the bevel edge inclines downwards from the inner end of the flow guiding device. The invention aims to provide the cable-stayed bridge steel plate composite beam, which can solve the wind vibration problem of the cable-stayed bridge, change the air flowing state and improve the wind-resistant stability.
本发明公开了一种可抗涡激振动的斜拉桥钢板组合梁，包括桥面板，桥面板的底部两端固定设置有钢主梁，钢主梁之间固定设置有钢横梁，钢主梁的侧端均固定设置有钢悬臂，钢主梁的底端设置有检修轨道，所述钢横梁的中部之间固定设置有垂直于钢横梁的稳定板，钢横梁的底端对称的设置有位于检修轨道内侧的导流装置；所述导流装置为直角三棱柱，导流装置截面的长直角边与钢横梁相贴合，短直角边与钢横梁相垂直，斜边由导流装置内端向下倾斜。本发明旨在提供一种可解决斜拉桥的风振问题，改变空气流动状态，提高抗风稳定性的斜拉桥钢板组合梁。
