STEEL BUILT-UP COLUMN
To provide a steel built-up column excellent in workability and economical efficiency, capable of easily, surely and nonrotatably extending a lower position stand column and an upper position stand column without increasing the number of part items.SOLUTION: A plurality (for example, three pieces) of stand columns 1, 2 and 3 are extended so as to partially overlap, and overlapping parts 11a and 12a (or 22a and 13a) of an extension end part 11 (or 22) of a lower position stand column 1 (or 2) and an extension end part 12 (or 13) of an upper position stand column 2 (or 3) are formed in a nonrotatable cross-sectional polygonal shape. The extension end part 11 (or 22) of the lower position stand column 1 (or 2) is formed by linking a diameter reduction part 11b (or 22b) of reducing a diameter upward in a taper shape and the overlapping part 11a (or 22a), and the extension end part 12 (or 13) of the upper position stand column 2 (or 3) is formed by linking a diameter expansion part 12b (or 13b) of expanding a diameter downward in a taper shape and the overlapping part 12a (or 13a).SELECTED DRAWING: Figure 1
【課題】部材点数を増やすことなく、簡易かつ確実に、下位の管柱と上位の管柱とを回転不能に継ぎ足すことができる、作業性、経済性に優れた鋼製組立柱を提供する。【解決手段】複数本（例えば３本）の管柱１、２、３を一部が重なり合うように継ぎ足してなり、下位の管柱１（又は２）の継ぎ足し端部１１（又は２２）と上位の管柱２（又は３）の継ぎ足し端部１２（又は１３）との重合部１１ａ、１２ａ（又は２２ａ、１３ａ）は回転不能な断面多角形に形成されている。前記下位の管柱１（又は２）の継ぎ足し端部１１（又は２２）は、上方へテーパー状に縮径した縮径部１１ｂ（又は２２ｂ）と前記重合部１１ａ（又は２２ａ）とが連設されてなり、前記上位の管柱２（又は３）の継ぎ足し端部１２（又は１３）は、下方へテーパー状に拡径した拡径部１２ｂ（又は１３ｂ）と前記重合部１２ａ（又は１３ａ）とが連設されてなる。【選択図】図１
