An adjustable concrete pier includes a concrete block having a central aperture extending from a top surface of the block to a bottom surface of the block. The pier includes a plate disposed at the top end of the concrete block, the plate having a hole aligned with the central aperture. An internal reinforcement framework is affixed to the plate and embedded within the concrete block. The central aperture receives a threaded rod to which is affixed a nut larger than the central aperture. A suitable support member, e.g. flat plate, U-shaped channel, etc., is disposed at the upper end of the rod. The internal reinforcement makes the pier much stronger as the load bears on the plate and internal reinforcement. Because the threaded rod is not embedded within the concrete, it can be replaced. This novel design also permits greater vertical adjustability. |
