JUNCTION STRUCTURE OF STEEL PIPE AND FOOTING AND STEEL PIPE/CONCRETE COMPOSITE STRUCTURAL PIER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To fix a leg of a hollow steel pipe to a footing with high strength, to be excellent in workability and to reduce a manufacturing cost of the hollow steel pipe.;SOLUTION: For a junction structure 21 of a hollow steel pipe and a footing according to the present invention, a hollow steel pipe 6 is joined to the footing so that the lower end thereof is buried in the footing 3, a communication hole 23 for communicating the inside and outside of the hollow steel pipe 6 is provided in a range to be buried in the footing 3 in a pipe wall 22 of the hollow steel pipe, and concrete 24 inside the hollow steel pipe 6 and concrete 25 spread around the hollow steel pipe are integrated through concrete 31 filled in the communication hole.;COPYRIGHT: (C)2013,JPO&INPIT
