Abstract
Abstract Each cast concrete pile section has longitudinally extending reinforcing rods, the opposite ends of which are partially received within openings formed through normally disposed end plates. The rod ends extend intermediate the length of the openings and are welded to the end plates about the inside faces of the plates with weld also being applied externally within the openings from the outer faces of the plates. The edges of the end plates are beveled and the sectional piles are welded about the adjoining beveled edges in end to end relation. In one form, an end plate on one pile section is formed with a central concavity while the end plate on the adjoining pile section has a complementary central convex portion adapted to be received within the concavity as to align the piles in coaxial relation one to the other.
