JOINING STRUCTURE OF STEEL PIPE COLUMN
PROBLEM TO BE SOLVED: To provide a joining structure of a steel pipe column which dispenses with welding work, is excellent in processability, and can sufficiently withstand a compression force.SOLUTION: In a joining structure of a steel pipe column for joining the steel pipe columns 3 to up-and-down directions, each of the steel pipe columns 3 comprises a diameter-contracted part 11 which is formed at an upper part, and gradually contracted in a diameter toward an upper end, a diameter-expanded part 12 which is formed at a lower part, and gradually expanded in a diameter toward a lower end, and a ring-shaped member 13 which is arranged at a lower part of the diameter-contracted part 11 being an external peripheral face of the steel pipe column 3. When the diameter-contracted part 11 of the lower steel pipe column 3 is inserted into the diameter-expanded part 12 of the upper steel pipe column 3, a lower end face of the upper steel pipe column 3 abuts on the ring-shaped member 13.SELECTED DRAWING: Figure 3
【課題】溶接作業が不要で施工性に優れ、かつ圧縮力に十分耐えることのできる鋼管柱の接合構造を提供すること。【解決手段】鋼管柱３を上下に接合する鋼管柱の接合構造は、鋼管柱３は、上部に形成され、上端に向かって次第に縮径する縮径部１１と、下部に形成され、下端に向かって次第に拡径する拡径部１２と、鋼管柱３の外周面であって、縮径部１１の下方に設けられるリング状部材１３とを備え、下側の鋼管柱３の縮径部１１を、上側の鋼管柱３の拡径部１２に挿入したときに、上側の鋼管柱３の下端面が、リング状部材１３と当接している。【選択図】図３
