Wind-resistant flexible wing plate and horizontal drawing cable bridge
The wind-resistant flexible wing plate comprises a wing plate body which is mounted on the side face of an external horizontal drawing cable bridge in a cantilever mode to guide wind flow, the wing plate body comprises a connecting section used for being connected with the external horizontal drawing cable bridge, and the connecting section extends outwards in the transverse bridge direction to form a cantilever section used for guiding the wind flow. By arranging the connecting section, the wing plate body can be connected with an external horizontal drawing cable bridge in an overhanging mode. Specifically, the connecting section located on the inner side is fixedly connected with the external horizontally-drawing cable bridge, and the overhanging section extends towards the side away from the external horizontally-drawing cable bridge and is overhung outwards, so that transverse air flow needs to be guided by the overhanging section before being blown to the external horizontally-drawing cable bridge; therefore, the aerodynamic shape of the bridge can be changed, the streaming form around the bridge is changed, vortex structures on the upper surface and the lower surface of the bridge are affected, and the purpose of improving the aerodynamic stability of the bridge is achieved.
本发明公开了一种抗风柔性翼板及平拉索桥，包括用于悬挑安装在外部平拉索桥侧面以引导风流的翼板本体，翼板本体包括用于与外部平拉索桥相连的连接段，连接段沿横桥向向外侧延伸成型有用于引导风流的悬挑段。通过设置连接段，使得翼板本体能够以悬挑状与外部平拉索桥相连。具体而言，即位于内侧的连接段与外部平拉索桥固定连接，悬挑段朝向背离外部平拉索桥的一侧延伸并向外挑出，以致横向风流吹向外部平拉索桥前需先经过悬挑段的引导，从而能够改变桥梁的气动外形、使得桥梁周围的绕流形态发生变化、影响桥梁上下表面的旋涡结构，进而达到提高桥梁气动稳定性的目的。
