Title:
PLASTIC RESIN GUARDRAIL
Document Type and Number:
WIPO Patent Application WO/2018/212450
Kind Code:
A1
Abstract:
The present invention relates to a plastic guardrail which is formed of a synthetic resin and is horizontally fixed to a vertical post. The guardrail of the present invention comprises: an external structure including a surface layer providing a contact surface against an external impact; an internal structure including a back surface layer positioned opposite to the external structure and providing a fixing surface for the vertical post; and a plurality of ribs for connecting the space between the external structure and the internal structure, wherein the surface layer is formed by mixing inorganic ceramic powders containing an anion-emitting material with a plastic resin such that anions are emitted from the surface layer, thereby creating an anionic atmosphere on vehicle roads. Meanwhile, the ribs are divided into first ribs and second ribs, which are arranged in a staggered manner by using an intermediate layer, such that the ribs are forcibly inserted into corresponding grooves on impact, thereby effectively mitigating the impact.
