<p><P>PROBLEM TO BE SOLVED: To provide a washing place floor pan capable of maintaining a drainage slope by suppressing the warpage due to thermal expansion when using a foam formed of a thermoplastic resin. <P>SOLUTION: The washing place floor pan comprises: a floor base material having higher strength than a thermoplastic foam plastic and showing a rectangular shape in vertical view, and a floor surface material which has a drain port and a wall panel placement part provided on the outer periphery where a wall panel is placed, the floor surface material being downwardly supported by the floor base material and formed of the thermoplastic foam plastic, having the surface in which the drainage slope is formed sloping down toward the drain port, and showing a rectangular shape in vertical view. The floor base material has an opening part passing through the floor base material in the vertical direction, at a position where it does not overlap with the wall panel placement part in vertical view. The floor surface material has an engaging part on the lower side for engaging with the edge of the opening part. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
