PROBLEM TO BE SOLVED: To reduce working man-hours with high loading efficiency, stabilized piles and simply without using a piling device for loading. SOLUTION: Loading construction of a wash-place loaded bathtub is so overlapped with the wash-place loaded bathtub 1 having reinforced ribs 11a and 12a on the rear sides of a wash-place 12 and a bathtub 11 that a bathtub 21 is set on the wash-place 12 upside down and that a wash-place 22 is set on the bathtub 11. Then, the rear side of a bathtub 31 side of a wash-place loaded bathtub 3 as the upper stage is overlapped with the rear side of the wash-place 22 side of a wash-place loaded bathtub 2 set on the upper side, the rear side of a wash-place 32 side is overlapped with the rear side of the bathtub 21 side to pile up, and the overlap mentioned above is successively repeated. |
