Abutting each other, fitting connection fitting of a ring-shaped connecting tool to both upper and lower connecting tools , or a connection pile in which the outer peripheral flanges of the upper and lower connecting tools are connected and fixed to each other with bolts or pins,
(1) The thickness of the cylindrical peripheral wall of the upper and lower connectors is formed with a thickness equivalent to the thickness of the pile, and a bolt hole is formed through the thickness of the peripheral wall in the axial direction. The holes corresponded to the screw holes in the end plate.
(2) The upper and lower connectors are fixed to the end plate of the upper pile or the end plate of the lower pile by screwing the bolt holes and the screw holes with bolts.
A connecting pile characterized by that.
