Document Type and Number:
WIPO Patent Application WO/2022/270262
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a joint pipe and methods of manufacturing and designing the same, a steel pipe with a joint pipe and methods of manufacturing and designing the same, a steel pipe pile, and a method of constructing a steel pipe pile with which it is possible to save time and effort for end part correction during attachment to a steel pipe, and which can be applied to a small-diameter steel pipe pile. For this purpose, a joint pipe 1 of a screw type or an insert type is attached to an end part of a steel pipe 3 to couple the steel pipe 3, wherein the outer diameter of a base end part 1a that is coupled to the steel pipe 3 is larger than the outer diameter of the steel pipe 3, the inner diameter of the base end part 1a is smaller than the inner diameter of the steel pipe 3, and in a state in which the pipe axis is aligned with the steel pipe 3, the amount of projection of the base end part 1a from an outer circumferential surface of the steel pipe 3 is less than or equal to 9 mm.
