JOINT STRUCTURE AND ITS EXECUTION METHOD FOR PILE

摘要

PROBLEM TO BE SOLVED: To execute an operation connecting a new pile to a pile already driven when a pile foundation is constructed easily and without being affected by weather. SOLUTION: An execution method connects a pair of piles A having a joint member B comprising an end plate 2 and a cylindrical side plate 3 fixed to the end part of a concrete main body 1. This method comprises the steps of mounting a guide jig 14 comprising a plurality of guide pieces 16 and a tightening ring 15 around the upper and part of the already driven lower side pile A, guiding the guide pieces 16 to align both axes of the piles A while lowering the lower end part of the upper pile A suspended from a crane, fitting the tip of a guide pin 4 installed projectedly from the end plate 2 of the lower pile A into a pin hole 5 provided in the end plate 2 of the upper pile A, axially aligning screw holes 6 provided in the upper and lower cylindrical side plates 3, and tightening a connecting piece to the cylindrical side plate 3 so as to connect the pair of the piles A to each other.
