  • Precast concrete foundation elements and system and method of using same
    Patent number: 4918891
    Abstract: A one-piece footing/pier foundation element (10) comprises a round concrete disc-shaped footing (24) with an elongated pier (18) extending from one side thereof. An elongated embedded pier bolt (36) extending from a top surface of the pier is used for carrying the footing/pier element and for holding a girder (72) mounted on top of the pier. The footing includes on a bottom surface thereof a stabilizing element (16,64) for preventing the footing/pier from moving laterally when in position and to prevent undue settling. The footing includes elongated footing voids (40,58) parallel with the elongated pier positioned about the pier for receiving footing bolts (14) for holding angle irons (76) extending between two footings. A system and method for using these footings/pier foundation elements involves boring appropriately positioned holes in the earth, placing the footing/pier elements in those holes and supporting a building from beams extending between top surfaces of the piers and the footings.
