Guardrail device applied to composite beam wind resistance

The invention discloses to a guardrail device applied to composite beam wind resistance. The guardrail device comprises a guardrail mechanism, a baffle and a steel box girder used for bearing loads, one end of the baffle is connected with the guardrail mechanism, the other end of the baffle is connected with the steel box girder, the baffle is in an arch shape, and the arching direction of the baffle faces the outer end. A guardrail base is arranged at the upper end of the steel box girder, and the lower end of the guardrail mechanism is connected with the guardrail base. One end of a baffle plate of the guardrail device is connected with the lower end of the guardrail mechanism, the other end of the baffle plate is connected with the steel box girder, the baffle plate is arched, the arched direction of the baffle plate faces the outer end, and the step height difference between the steel box girder and the guardrail mechanism is transited by adopting the arched baffle plate, so that the sudden change of the
