Abstract:
1. An article for coaxially joining concrete piles subjected to large vertical axial forces during pile driving comprising: an annular plate which is mounted at one end of the pile, having a central opening, a front surface and an obverse surface, the front surface provided with an interlocking profile having a plurality of first and second complementary configurations, each configuration is defined in a substantially equal-sized sector and arranged radially in an alternate fashion on the front surface, where the first configuration is a protrusion and the second configuration is a recess, wherein the lateral edges of each protrusion form a tapered horizontal groove extending toward the central opening; whereby mating of two identical annular plates, that are each mounted at the ends of two separate piles, at the interlocking profiles through registering the protrusions of one article to the recesses of another article lead to the formation of a passageway by two adjacently positioned grooves of two contiguous protrusions of the mated articles, the passageway allows interlocking of the mated articles by inserting a tapered pin there through.
