Combined bridge wind barrier

The invention relates to a combined bridge wind barrier. The combined bridge wind barrier is composed of a plurality of basic combined bridge wind barrier units, wherein a wind barrier bracket of each combined bridge wind barrier unit is composed of a side column or a middle column, a middle column as well as an upper beam, a middle beam and a lower beam in the middle part; a plurality of rows of wind barrier plates are arranged between two beams; and a plurality of columns of wind barrier plates are arranged between two columns. When the combined bridge wind barrier in the invention is adopted, a part of air flows can be allowed to pass through the wind barrier plates, and a structural measure that the flow section is gradually expanded in size is utilized, so that the influence of the air flow on driving is reduced; the type I wind barrier plates reduce the air flow velocity and the aerodynamic resistance by wind barrier gratings formed by triangular prism strips; and the type II wind barrier plates (11) reduce the air flow velocity and the aerodynamic resistance by use of wind passing holes. The ventilation rate of the wind barrier is flexibly adjusted by use of the wind barrier plates arranged into a plurality of layers to guarantee the safety of driving and bridges; and the type I wind barrier plates play a role of wind barriers on one hand and play a role of anti-glare panels on the other hand.
