Kind Code:
B2
Abstract:
To provide a screw joint which can sufficiently utilize a total plastic load of a joint steel material without coming off a screw part on a compression side in an incomplete joint state where a shoulder part is not touched, and to provide a steel pipe with a screw joint, a structure, a method for constructing the structure, a landslide control steel pipe pile, a method for constructing the landslide control steel pipe pile, a method for designing the screw joint, a method for manufacturing the screw joint, and a method for manufacturing the steel pipe with the screw joint, on the premise of the screw joint.SOLUTION: A screw joint 1 for joining steel pipes 3 on ends of the steel pipes 3 includes: a male side cylindrical body 7 having a male screw 5 composed of a tapered screw; and a female side cylindrical body 11 having a female screw 9 composed of a tapered screw, in which an inclination angle to a direction perpendicular to an axis of the steel pipe of stabbing surfaces 5a and 9a of a screw thread in the male screw 5 and the female screw 9 is within a range of 0-8 degrees.SELECTED DRAWING: Figure 1
