PROBLEM TO BE SOLVED: To manufacture an inclined concrete floor for a dangerous-article storage shed in a factory, without casting it in place. SOLUTION: A wavy steel sheet 12 is stretched on a floor frame 11, and concrete 15 is placed after a wire net 13 for reinforcing concrete is placed on the sheet 12. A floor panel 10 is cured by steam in the state of being put into an enclosure after a lapse of half a day from placing, so as to bring out the strength of the concrete. The completed floor panel 10 is installed on a ground sill 16 of the shed in the state of shop assembly. Struts 19 are precedently erected and welded in important positions on the sill 16. The floor panel 10 is supported by making the frame 11 placed on the struts 19. The respective struts 19 are not uniform in height; the strut nearer to a drain retainer 9 is made lower; and the strut farther away from the drain retainer 9 is made higher. This makes the floor panel 10 installed in the state of being inclined toward the drain retainer. COPYRIGHT: (C)2006,JPO&NCIPI
