Further, the bridge floor column member comprises a lamp pole, a sign pole and a portal frame.
After the technical scheme is adopted, the utility model discloses following beneficial effect has:
(1) the disconnected guardrails are connected into a whole, so that the safety protection capability of the guardrail at the conflict position is improved;
(2) the disassembly and the assembly are simple and convenient, and the maintenance work is convenient;
(3) the reinforcing member is consistent with the collision surface of the beam in the beam column type guardrail, so that the landscape effect is not influenced;
(4) saves the engineering cost and conforms to the environmental protection concept.
