<P>PROBLEM TO BE SOLVED: To obtain a column structure which increases the adhesion of a steel pipe to a filler infilled into the steel pipe, and a method for constructing the column structure. <P>SOLUTION: The column structure 20 includes the steel pipe 12, a concrete precast member 14 which is arranged inside the steel pipe 12 in such a manner as to make a gap between itself and an inner wall of the steel pipe 12, and the filler 16 which is infilled into the gap between the steel pipe 12 and the precast member 14. In this case, the precast member 14 serves as a core material by infilling the filler 16 into the gap between the already hardened steel pipe 12 and the precast member 14; and the filling amount of filler 16 can also be reduced. Thus, the amount of hardening shrinkage of the filler 16 becomes smaller than in the case where the inside of the steel pipe 12 is filled with only concrete, so that the adhesion of the steel pipe 12 to the filler 16 can be enhanced. <P>COPYRIGHT: (C)2011,JPO&INPIT |
