Title:
HORIZONTAL SUPPORT FORCE REINFORCEMENT AND CONTROL SYSTEM OF GUARDRAIL INSTALLED ON SLOPE, HORIZONTAL SUPPORT FORCE REINFORCEMENT AND CONTROL STRUCTURE OF GUARDRAIL INSTALLED ON SLOPE, AND GUARDRAIL INSTALLATION METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/105959
Kind Code:
A1
Abstract:
The present invention reinforces, with a horizontal support force reinforcement structure, a shortage of a horizontal support force of a guardrail pillar caused by a "guardrail installation width at a banking section of a slope" being typically formed narrower than a prescribed tolerance, and at the same time allows an impact load to be absorbed by the horizontal support force reinforcement structure and allows absorption due to bending deformation to precede absorption due to reaction, thereby preventing risk to life due to an initial impact reaction force, as well as significantly reducing the magnitude of the reaction force due to the reaction, which is a main cause of subsequent primary and secondary accidents. In addition, the present invention has a simple horizontal support force reinforcement structure, which makes it easy to repair and newly install a guardrail, thereby making said installation efficient and economical.
