ABSTRACT:
An adjustable pier block for leveling a deck or porch is disclosed. A footing block or base is cast of concrete and a threaded rod is placed vertically therein. A coupling having internal threads and a plurality of flats on an outer surface thereof is threaded onto the rod. A U-shaped saddle member, sized to receive a joist or beam, has a connector attached to a bottom outer surface thereof. The connector is sized and shaped to slidingly receive a free end of the coupling against a load bearing surface or the bottom side of the saddle. A washer or disk, of made from a friction reducing material, can be inserted between the coupling and the load bearing surface for ease of operation. The coupling can be turned, by use of a wrench cooperating with the flats, in order to raise or lower the beam or joist for leveling a deck during construction thereof and at a later date after settling has occurred.
