Rectification device for vortex-induced vibration control of inverted trapezoidal plate truss combined steel truss girder bridge

The utility model discloses a rectifying device for vortex vibration control of an inverted trapezoidal plate-truss combined steel truss girder bridge, which comprises a rectifying plate arranged along the bridge direction, the rectifying plate is of a flat plate structure, and the rectifying plate is arranged on the outer side of an inverted trapezoidal plate-truss combined steel truss girder side longitudinal beam web. The rectifying plate is obliquely arranged relative to the edge longitudinal beam web, and the field angle between the rectifying plate and the horizontal plane is upward. The rectifying plates are arranged on the outer sides of the webs of the side longitudinal beams, and the field angles between the rectifying plates and the horizontal plane are upward, so that the flow field characteristics of the upper part and the side surface of the inverted trapezoidal plate truss combined steel truss girder can be changed, the generation of vortexes is inhibited or large vortexes are broken, the vorte
