PURPOSE: A bar support for a mass reinforced concrete member and a method of upper bar arrangement using the same are provided to accurately position an upper reinforced concrete member by adjusting the height of a bar support. CONSTITUTION: A bar support(100) for a mass reinforced concrete member comprises three or more vertical main bars(110), a horizontal pressure plate(120), an upper support plate(130), a height adjusting unit(140), a mounting unit(150), and a horizontal bar(160). Three or more vertical main bars are vertically positioned in a polygon shape. The horizontal pressure plate comprises a projecting end(111) and is positioned in a lower vertical main bar. The upper support plate is fixed to the upper end of the vertical main bar. The height adjusting unit is adjustably mounted in the upper support plate in the vertical direction by penetrating the upper support plate. The mounting unit is mounted on the upper end of the height adjusting unit. The horizontal bar is installed between the horizontal pressure plate and upper support plate in order to reinforce the vertical main bar. The horizontal rod is installed at the enforcement of the vertical column radical between the horizontal anchor plate and upper support plate. |
