Title:
FOUNDATION PILE
Document Type and Number:
Japanese Patent JP2016014226
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a foundation pile of which resistance against subsidence and extraction is improved readily using a general-purpose tool after being driven.SOLUTION: A foundation pile has a tapered part 30 at a tip 23 of a pipe-form pile body 20, and has a tip side member 60 and a rear end side member 40 installed in front of and behind the tip 23, leaving an interval. Deformation facilitating means Ts, Ys1, Ys2 and Ys3 are installed on walls 25, 35 that constitute the tapered part 30 and the pile body 20 at the part between the tip side and the rear end side, so as to cause the walls 25, 35 get deformed by protruding or extending outward while being divided along a circumferential direction of the foundation pile, when the part between the tip end side and the rear end side is compressed and the interval therebetween is made smaller. The tip side member 60 and the rear end side member 40 are connected to the pile body 20 with a screw structure that can decrease the interval between the tip end side and the rear end side by tightening with a tool inserted from an opening on the rear end side. The pile is thus deformed by tightening the screw after being driven, and thereby enhanced in resistance against subsidence, etc.
