摘要

PURPOSE: A median strip for controlling the height of a road is provided to improve the convenience on construction and maintenance and to improve economical efficiency. CONSTITUTION: The median strip for controlling the height of a road contains a footing concrete backing plate, galvanized posts, a fastening bolt and a guardrail and is installed on the central line of a road. The galvanized posts(300,300') erected on the upper part of the footing concrete backing plate(100) are fixed to a post guide block(200) to be reciprocated in 2-stage and controlled widthwise. Many guide block laying grooves(110) are formed in the rectangular shape on the footing concrete backing plate(100) and coupled with a post guide block(200) having many post holes(210). The lower galvanized post(300) is provided with many fastening bolt holes(310) and the upper galvanized post(300') is provided with many fastening holes(310',330'), so that the galvanized posts(300,300') are fixed by fastening with fastening bolts(380). The guardrail(500) is fastened to the upper galvanized post(300') to be controlled widthwise by a width-control bolt(400), a bolt connector(420) and a nut(450).
