To provide a metal hollow hole columnar body that has light weight and compact shape and can be easily transported and assembled.SOLUTION: A metal plate column 2 and a metal plate column 3 are fixed through a metal plate column 1 so as to face in their lengthwise direction. An end face in the lengthwise direction of the metal plate column 1 and facing surfaces of the metal plate column 2 and the metal plate column 3 are joined or fused and fixed. An outward surface of the metal plate column 2 and an outward surface of the metal plate column 3 are parallel on a cross section perpendicular to the lengthwise direction of the metal plate column 2 and perpendicular to the outward surface facing the outside of the metal plate column 2. Width W1 of the metal plate column 1 is narrower than width W2 of the metal plate column 2 and width W3 of the metal plate column 3. The cross section is hollow hole. In a metal hollow column body, distance between the outward surface of the metal plate column 2 and an end of the hollow hole on the outward surface side of the metal plate column 2 is larger than thickness of the metal plate column 2, while distance between the outward surface of the metal plate column 3 and the end of the hollow hole on the outward surface side of the metal plate column 3 is larger than thickness of the metal plate column 3.SELECTED DRAWING: Figure 2

    【課題】軽量かつ形状がコンパクトで移送や組立が容易な金属製中空孔柱状体の提供【解決手段】金属プレート柱1を介して、金属プレート柱2と金属プレート柱3とがその長さ方向に対向して固定され、金属プレート柱1の長さ方向の端面と、金属プレート柱2及び金属プレート柱3の対向面とは接合又は融合して固定され、金属プレート柱2の長さ方向に垂直で金属プレート柱2の外部に向く外向面に垂直な断面において、金属プレート柱2の外向面と金属プレート柱3の外向面とは平行で、金属プレート柱1の幅W1は、金属プレート柱2の幅W2及び金属プレート柱3の幅W3よりも小さく、断面は中空孔であり、金属プレート柱2の外向面と、金属プレート柱2の外向面側の中空孔の端部との距離は金属プレート柱2の厚みより大きく、金属プレート柱3の外向面と、金属プレート柱3の外向面側の中空孔の端部との距離は金属プレート柱3の厚みより大きい金属製中空柱体。【選択図】図2
