PROBLEM TO BE SOLVED: To provide a basic structure of an independent pile, without a basic beam connecting a pile head with a connection beam firmly, while absorbing misalignment of a plurality of piles in a basic construction method of connecting the pile head applied to additionally build a superstructure at an upper part by avoiding existing facilities, such as a platform of a railway station and eliminating the basic beam by connecting a plurality of the pile heads with the connection beam. SOLUTION: The pile heads 11a of four driven steel piles 11 are cut with their heights uniformed, and a steel cap 13 with a top end plate 12 is welded to the pile head 11a; a top end part of the connection beam 14 is placed on the top end plate 12; a lower end of a connection bolt 16 inserted into a through hole 15 with a gap is screwed to a lower nut 16a; and an upper end of the connection bolt 16 is passed through a blocking plate 17 blocking an upper opening of the through hole 15 and is screwed and fastened to an upper nut 16b, so that the top end of the connection beam 14 is fixed to the steel pile 11. The gap between the through hole 15 and the connection bolt 16 is filled with a filling material 18. COPYRIGHT: (C)2007,JPO&INPIT
