Abstract
PURPOSE: To simplify structure by forming a steel-pipe reinforced-concrete pole member by forming irregularities to the internal surface of a steel pipe having a concrete placing space on the inside and a fire-resistive covering on the outer circumference of the steel pipe respectively. CONSTITUTION: A steel pipe 2 is formed in a closed sectional-shaped square cylindrical cross section. Irregularities 2a having a corrugated shape or the like are formed to the whole surface of an internal surface 2b in the internal surface 2b of the steel pipe 2, a region surrounded by the internal surface 2b is used as a concrete placing space 3, and concrete is poured and placed into the space 3. The fire resistive covering 5 of precast concrete is formed on the outer circumference of the steel pipe 2, and the steel-pipe reinforced-concrete pole member 1 is constituted. Accordingly, concrete placed into the space 3 can be worked so as to be able to be attached with the steel pipe 2 under an excellent state in the irregularities 2a.
