Title:
鋼管柱の補強構造
Document Type and Number:
Japanese Patent JP6551298
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To effectively reinforce a bent position being a point which is particularly severe in terms of stress while suppressing the overlap of weld lines, in a steel pipe column having the bent position in which an angle formed of a horizontal face is changed.SOLUTION: A reinforcing structure of a steel pipe column comprises: a rib 12 which is arranged so as to contact with at least a part of an inner face of the steel pipe column 100 in a bent position 100D, and to progress along a direction in which the inner face of the steel pipe column 100 extends, and attached to the inner face of the steel pipe column 100 by welding; an inner steel pipe 14 which is arranged inside the steel pipe column 100, whose upper end part is located above the bent position 100D, whose lower end part is located below the bent position 100D, and which is embedded into a support baseboard 204 at its lower end part; and a connecting steel material 16 which is arranged in a substance-horizontal direction at its longitudinal direction, and connects the rib 12 and the inner steel pipe 14. In the steel pipe column 100, concrete 18 is charged up to at least an upper part rather than the bent position 100D.SELECTED DRAWING: Figure 2
