ABSTRACT:
A foundation system which includes the use of a coupled piling of solid bars for supporting a structure in which the solid bars are coupled together in a contacting relationship. The coupled piling bars comprise a first and a second solid bar, one end of the first bar and the other end of the second bar adapted to be placed in an aligned, contacting, supporting relationship, each bar having a pin-retaining cavity spaced apart a short distance from the end of each bar, and each end having a pin-retaining ring-receiving cavity at each opposing end of the bar, to receive a pin-retaining ring. The first and second bars are coupled together through an outer housing which fits over the outer surface of the opposing ends of the first and second bars, and containing first and second pins and springs, to bias the pins inwardly toward the center of the coupling, and retaining-pin rings in the housing, to retain the first and second pins in an open tensioned position. When the first end of one bar and the other end of the second bar are slid into closing contact, the retaining ring fits in the retaining-ring cavity, and the first and second pins slide into the respective pin-receiving cavities at the end of each bar, to retain the solid bars in a close, supporting, aligned position.
