<P>PROBLEM TO BE SOLVED: To provide a foundation structure of a tower-like structure such as a support and a tower, which has a column base portion fully fixed by means of an unbonded anchor for introducing prestress, and which suppresses the appearance of a crack in concrete to the utmost. <P>SOLUTION: A vertical reinforcement 7 is arranged in parallel with the longitudinal direction of the unbonded anchor 5 for introducing the prestress, which is laid between a base plate 4 and an anchor plate 6, concentric with the tower-like structure 1; the vertical reinforcements 7 are joined to a tie hoop 8; and horizontal reinforcements 9 are arranged radially around the center of the cross-section of the tower-like structure 1 in such a manner as to cross the unbonded anchor 5 and the vertical reinforcement 7. A lower end of the vertical reinforcement 7 is elongated to a footing portion 3a of the foundation 3. These reinforcements are arranged; the concrete 10 is placed; and an outside diameter of a base portion 3b is large enough to enable the arrangement of the horizontal reinforcement 9. <P>COPYRIGHT: (C)2010,JPO&INPIT |
