Title: OPEN TYPE PLASTIC GUARDRAIL
Abstract:
The present invention relates to an open type plastic guardrail made of a synthetic resin material, and fixed to vertical posts in a transverse direction with a gap in a vertical direction so as to ensure vision of a driver to open. The guardrail is formed to be integrally extruded while comprising: a planar supporting part for providing a fixing surface for the post; and a protruding part having one or more semicircular protrusions formed toward the front of the supporting part, wherein the supporting part has a fitting groove formed therein, and the protrusion has a rib, which can be closely inserted into the fitting groove and formed at the position corresponding to the inner fitting groove, such that when an impact is applied to the protrusion, the impact is relieved by a continuous friction resistance while the rib is forcibly inserted into the fitting groove.
