MEDIAN GUARD RAIL

摘要

The present invention relates to a median guard rail having a closed cross-section. The median guard rail comprises a plurality of posts vertically standing on a ground at regular intervals on a center of a road, with at least two blockouts connected to each post in a longitudinal direction, and with an upper rail and at least one pair of lower rails respectively connected to the blockout. The post has a hollow elliptical cross-section with varied thicknesses, where a front surface and a rear surface have the highest thickness with gradually reducing thickness towards the two lateral surfaces. The upper rail provided on an upper portion of the post is fastened with an adjacent upper rail in a longitudinal direction, through an upper sleeve inserted inside the upper rail. The lower rail is fastened with an adjacent lower rail in a longitudinal direction, through a lower sleeve inserted inside the lower rail.
