PURPOSE:To facilitate installation of a wall material by structuring a column hollow, and forming a left and a right detention part for detaining the wall material on the outside in such a way as stretching in the longitudinal direction of the column. CONSTITUTION:A square inner cylinder 11 is provided in the center of a column 1 constructed from aluminum material through an extrusion process, and an outer cylinder having a circular section is furnished outside of this inner cylinder 11 concentrically therewith. On the outside surface of the outer cylinder 12, detent projections 15, 15 forming pairs and stretching plumb are provided at 90-deg. intervals, wherein the width of the projection 15 is set equal to or a little larger than the width of outer wall panel 2. Gypsum boards 22, 23 are affixed to the front and rear of a wood panel 21 to form a core, and an outer wall panel 2 is constructed. The side end of this panel 2 is inserted between the projections 15, 15, and the end of panel 2 and the projection 15 are fixed together using bolt, etc. This enables performing easy installation of panel 2 as a wall material. |
