PURPOSE: An impact post support is provided to improve the surface anchoring force of a post and reduce working times and manpower by simplified transportation and installation processes. CONSTITUTION: An impact post support comprises a widening type buried portion(20), an impact portion(10), and a rotating type buried portion(30). Multiple cutout portions(21) and a retreated groove(22) are formed in the rotating type buried portion. The lower circumference of the multiple cutting portions is vertically cut at fixed intervals. A retreated groove is formed on the upper side. The impact portion is installed inside the widening type buried portion, so that the cutout portion is widened to the outside direction. The rotating type buried portion is positioned on the top of the widening type buried portion. A through-hole is formed on the rotating type buried portion. |
