A connecting fitting 42 is provided at the joint between the lower part of the column 1 and the end of the floor beam 2 and is joined by welding. A connection fitting 43 is provided at the joint between the upper part of the column 1 and the end of the ceiling beam 3 and joined by welding. The column at the right front corner of the building unit U1 with a temporary column in FIG. 1 is a temporary column 11 that is finally removed. Although not shown, an intermediate column may be provided at an appropriate position between the floor beam 2 and the ceiling beam 3.

  As shown in FIG. 2, the temporary column 11 includes an upper column 53, a lower column 52, and a wedge member 6 provided on the same axis as the temporary column. The upper column 53 is joined to the ceiling beam 3, the lower column 52 is joined to the floor beam 2, and the wedge member 6 has an inclined upper surface.

  The wedge member 6 has an inclined upper surface and a horizontal surface on the lower surface. Further, as shown in FIG. 2, the wedge member 6 is made smaller than the upper column and the lower column so that the wedge member 6 does not protrude from the temporary column 11 even when the wedge member 6 is moved horizontally. Further, the wedge member 6 is provided at a position sandwiched between the upper column 53 and the lower column 52. The height of the temporary pillar is adjusted by horizontally moving the wedge member 6.

  A connecting part 531 is provided on the upper part of the upper pillar 53, and a connecting part 521 is provided on the lower part of the lower pillar 52.
