摘要： PROBLEM TO BE SOLVED: To provide a joint structure and its connecting method for obtaining strong joining strength by connecting mutual steel columnar bodies such as a steel pipe pile in a short time without welding.
SOLUTION: An annular body as a male side joint 13 having a cutout part 14 is arranged in a shaft directional end part of one steel columnar body 11 to be connected. An annular locking part 13a is arranged on an outer peripheral surface of the male side joint 13. A female side joint 22 having an annular locking part 22a on an inner peripheral surface is arranged in a shaft directional end part of the other steel columnar body 21 to be connected. The cutout part 14 extends over the shaft directional total length of the male side joint 13. When fitting the male side joint 13 in the female side joint 22, fitting of both is facilitated by reducing an interval of the cutout part 14, and joining between both is strengthened by expanding the interval of the cutout part 14 after fitting.

摘要： PROBLEM TO BE SOLVED: To provide a joint structure between a steel pipe pole using a multi-segment diaphragm and a steel beam of stable quality and inexpensive.
SOLUTION: The diaphragm 2 consists of four multi-segment diaphragms 2a which are formed by dividing the diaphragm 2 into a plurality of diaphragms in the circumference of the steel pipe pole 1. The steel beam 3 is connected by welding to the multi-segment diaphragm 2a, and the multi-segment diaphragms 2a, 2a adjacent to each other are partial penetration welded (B). Thus, since there is no need to consider a cross-section loss in the diaphragm caused by a bolt hole, it does not result in an increase in the width of the diaphragm or the plate thickness of the diaphragm. Thus, a steep rise in material costs of the diaphragm or the like can be controlled, and the inexpensive joint structure of stable quality can be provided.

Annular bodies 22 having steps 23 are mounted at upper ends of the cylinders 21 on lower sides. When the upper/lower cylinders 11 and 21 are made close to each other gradually, the tapered engaging sections 14 are brought into contact with upper/end corners of the annular bodies 22 on the lower sides, drums of the flexible bodies 13 are deformed elastically to internal surface sides of the cylinders 11 and 21, and the engaging sections 14 ride on internal surfaces of the annular bodies 22 on the lower sides. When lower end faces of the annular bodies 12 on the upper sides and upper end faces of the annular bodies 22 on the lower sides are abutted, the arcuate flexible bodies 13 are returned to initial states by their own elastic forces, the engaging sections 14 are engaged at lower ends of the stepped sections 23, and connections of the cylinders 11 and 21 are completed.
