The present invention relates to a guard rail post having an anti-rotation function including a concrete base that is disposed to be buried under the ground and has multiple anchor bolts formed to protrude at an upper end; pillar fixing means that is disposed in an upper portion of the concrete base through the anchor bolt and has a cylindrical pillar connection pipe formed to extend at the center; and a pillar that is disposed to extend in a vertical direction in an upper portion of the pillar fixing means through insertion coupling with the pillar connection pipe and is fixedly fastened to the pillar connection pipe through fastening coupling with a fastening bolt. Multiple rack grooves concave along a circumference of the pillar are further formed at a lower end of the pillar, and a limit protrusion is further formed to protrude outside a lower end of the pillar connection pipe to be hooked by the lack groove and limit the rotation of the pillar from the pillar connection pipe. According to the present invention, the pillar of the guard rail can be easily installed and replaced, thus maintenance costs can be saved. Also, the guard rail can be easily installed along a curved section of a road by rotating the pillar during installation as in the related art. In addition, the rotation of the pillar is limited after the installation so that the basic safety of the guard rail for preventing an accident due to a vehicle collision can be ensured. |
