Claims

[Scope of claims for utility model registration] (1) The cross-sectional shape is circular and the wall thickness is 4.5 to 2.
A 2 mm steel pipe 1 is configured in a tapered shape with its end portion 1A and base portion 1B in the range of 1/150 to 1/30, and is cured at room temperature and pressure to have a compressive strength of 500.
Kg/cm ² or more of concrete 2 is tightly integrated with the inner surface of the steel pipe 1 to form a hollow cylindrical shape with a wall thickness in the range of 50 to 150 mm, and the base end is lower than the end end 1A. A steel-tube-concrete composite hollow pole characterized by having a tapered structure with a thick wall on the part 1B side. (2) Ring-shaped joint end plates 3 and 4 are integrally provided on each end face of the distal end portion 1A and the base end portion 1B of the steel pipe 1, extending inside and outside in the radial direction of the steel pipe 1, and these joint ends A claim characterized in that portions 3A and 4A of the plates 3 and 4 located on the center side of the steel pipe 1 are configured to double as support plates that support the respective ends 2A and 2B of the concrete 2. The steel pipe concrete composite hollow pole described in (1).
