<p><P>PROBLEM TO BE SOLVED: To provide a pile head joint structure capable of adjusting a construction error of a pile and easily and surely joining a pile and a structure. <P>SOLUTION: The pile head joint structure includes: a flange 4 which is joined to an upper end part 2a of a pile 2, and for which a plurality of first hole parts 11 extended in an arcuate shape in a circumferential direction centering on a center axis of the pile 2 are arrayed in the circumferential direction on the side of an outer edge part 4c; a joining plate 5 which is piled up on the flange 4 and joined, to which a support member (structure) 3 is joined, and for which a plurality of second hole parts 12 extended in a radial direction from a center part 5a to the side of an outer edge part 5c are arrayed with a gap from each other in the circumferential direction; a plurality of first fasteners 6 inserted to the first hole parts 11 and the second hole parts 12 to fix the flange 4 and the joining plate 5; and a plurality of fasteners 7 for joining the joining plate 5 and the structure. The joining plate 5 is configured such that a distance l2 from the center part 5a to a second bolt hole (attaching position of the second fastener) 5b is longer than a distance l1 from the center part 5a to the second hole parts 12. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
