Definitions

  • a gear-type joint structure of a steel-pipe pile is used, and although this joint structure is based on the screw type, the problems of a screw-type joint structure of a steel-pipe pile are solved.

  • the engagement convex portions are intermittently provided in the circumferential direction of the steel-pipe pile, and thus, are provided in a row in the axial direction. Accordingly, a cross-sectional defect occurs when viewed in the axial direction, and the bending load and the tension load which can be transmitted to the engagement convex portion are decreased by the cross-sectional defect. Therefore, in the joint structure of a steel-pipe pile disclosed in Patent Document 3, in order to withstand a predetermined bending load and tension load, it is necessary to use the engagement convex portion enlarged by the cross-sectional defect when viewed in the axial direction, and it is necessary to increase the number of steps of the engagement convex portion in the axial direction. Accordingly, there is a problem that machining costs and the cost of materials in the joint structure of the steel-pipe pile increase.
  • the present invention is made in consideration of the above-described problems, and an object thereof is to provide a joint structure of a steel-pipe pile and a steel-pipe pile in which an increase in labor for rotation of the steel-pipe pile at a work site is prevented, an excessive increase in a plate thickness of the steel-pipe pile is avoided, and there is no concern of damage even when the bending load is applied.

  • the loads transmitted from the external fitting convex portions and the internal fitting convex portions to a main body of the steel-pipe pile can be uniform in the circumferential direction, and an increase in a plate thickness of the steel-pipe pile can be avoided.

  • any external fitting convex portion of the plurality of rows and any internal fitting convex portion of the plurality of rows can be accurately disposed on a portion corresponding to the outermost edge end portion of the steel-pipe pile at which tensile stress becomes the maximum. Accordingly, the bending load can be accurately applied to any external fitting convex portion and any internal fitting convex portion, and it is possible to avoid a case where the external fitting end portion and the internal fitting end portion are damaged.

  • the external fitting convex portions provided in each of the plurality of step portions are formed to fill gaps along the circumferential direction when viewed in the axial direction of the steel-pipe pile, contact areas between the external fitting convex portions and the internal fitting convex portions are maximized, and load bearing capacity with respect to the tensile load and the bending load can be increased.

Accordingly, a structure in which the plate thickness of the steel-pipe pile is increased in stages according to the number of steps of the external fitting convex portions and the internal fitting convex portions in the axial direction can be easily realized.
  • the tip portion of the external fitting end portion and the internal fitting edge of the internal fitting end portion abut each other, and thus, complete fitting between the external fitting end portion and the internal fitting end portion can be visually confirmed from the outside.

  • the plate thicknesses of the lower steel-pipe pile 2 and the upper steel-pipe pile 3 are thickened in stages from the outer side (upper side) toward the inner side (lower side) in the axial direction X of the lower steel-pipe pile 2 and from the outer side (lower side) toward the inner side (upper side) in the axial direction X of the upper steel-pipe pile 3, and the external fitting step portion 29 and the internal fitting step portion 39 are formed. Accordingly, also in the second embodiment, the structure in which the plate thicknesses of the lower steel-pipe pile 2 and the upper steel-pipe pile 3 increase in stages according to the number of steps of the external fitting convex portions 21 and the internal fitting convex portions 31 can be easily realized.
  • the external fitting convex portions 21 of the first external fitting step portion 29a and the external fitting convex portions 21 of the second external fitting step portion 29b are provided at positions which deviate in the axial direction X
  • the external fitting convex portions 21 of the second external fitting step portion 29b and the external fitting convex portions 21 of the third external fitting step portion 29c are provided at positions which deviate in the axial direction X.
  • the external fitting convex portions 21 of any of the first external fitting step portion 29a, the second external fitting step portion 29b, and the third external fitting step portion 29c, and the internal fitting convex portions 31 of any of the first internal fitting step portion 39a, the second internal fitting step portion 39b, and the third internal fitting step portion 39c can be accurately disposed at the portions corresponding to the outermost edge ends of the lower steel-pipe pile 2 and the upper steel-pipe pile 3 at which the tensile stress is maximized.
  • the bending load is accurately applied to any of the external fitting convex portions 21 and any of the internal fitting convex portions 31, and it is possible to avoid a case where the external fitting end portion 20 of the lower steel-pipe pile 2 and the internal fitting end portion 30 of the upper steel-pipe pile 3 are damaged.
  • the present invention is not limited to the above, and for example, the external fitting convex portions 21 of the first external fitting step portion 29a and the external fitting convex portions 21 of the second external fitting step portion 29b may be provided at positions which deviate in the axial direction X, and the external fitting convex portions 21 of the second external fitting step portion 29b and the external fitting convex portions 21 of the third external fitting step portion 29c are provided at positions matched in the axial direction X. Also in this case, the cross-sectional defect does not occur when viewed in the axial direction, and the loads transmitted from the external fitting convex portions 21 and the internal fitting convex portions 31 to the main body of a steel-pipe pile can be uniform in the circumferential direction.
  • the external fitting convex portions 21 of one external fitting step portion 29 and the external fitting groove portion 22 of the other external fitting step portion 29 may be provided to be adjacent in the axis orthogonal direction Y when viewed in the axial direction X.
  • the first embodiment shows the case in which the number of steps in each of the external fitting step portion 29 and the internal fitting step portion 39 is two
  • the second embodiment shows the case in which the number of steps in each of the external fitting step portion 29 and the internal fitting step portion 39 is three.
  • the number of steps is two.
  • the thicknesses in the inner sides in the axial direction X can be thinned while the thicknesses of the tip portions (the outer sides in the axial direction X) of the external fitting step portion and the internal fitting step portion are maintained in certain thicknesses or more. Accordingly, the increase in the cost of materials due to the increase in the plate thickness of the steel-pipe pile can be prevented.
