<P>PROBLEM TO BE SOLVED: To enable a construction cost as well as a construction period to be reduced, in a structure with a rigid frame supported by pile foundations, in a manner that omits a foundation beam in a central portion of a span by allowing slab concrete positioned in the central portion of the span of the rigid frame to substitute a function of the foundation beam and thereby reducing: an excavation volume to construct the foundation beam to secure a degree of fixation at a column base section; and material costs for reinforcement as well as concrete of the foundation beam. <P>SOLUTION: In a structure which has a rigid frame 1 supported by pile foundations 3 and slab concrete 2, a degree of fixation at column base sections is secured and a foundation beam at a central portion of a span is omitted by: installing edge portion reinforcement sections 4 with shapes of the foundation beams at edge portions of the slab concrete in the column base sections at both ends of the rigid structure; and allowing the slab concrete to substitute a function of the foundation beam in the central portion of the span of the rigid frame. <P>COPYRIGHT: (C)2013,JPO&INPIT |
