Then, the ground is excavated, the frames 12 are fixed by placing concrete subslab base 116 and a base concrete 120, a floor board 122 made of a rust preventing member in which a foaming material 124 is sprayed on the back is laid, a side wall board 134 made of a rust preventing member in which a foaming material is sprayed is erected, a concrete 140 is placed between it and the ground, and the tables 14 and 16 and the elevating device are assembled. A motor 46 is driven, a column body 36 with a screw is rotated through a chain 44 and a gear 46, and the tables 14 and 16 are vertically moved along the frame 12.
