PROBLEM TO BE SOLVED: To provide a wash place floor which causes no discontinuation of water flow at downstream of a drain ditch in an early stage, preventing the occurrence of residual water on the surface of the wash place floor, particularly around a drainage recess. SOLUTION: A wash place floor made of a resin includes a surface inclined downward toward the top edge of a drainage recess. The downstream part of a drain ditch 12 arranged on the surface 2 includes a water conducting groove part 21 continuously arranged up to the height lower than or equal to the top edge 32a of a rising surface part 32 so as to conduct the water at the downstream of the drain ditch 12 to below the top edge 32a of the rising surface 32 of a drainage recess 6, and a flow rate control part 22 which is arranged discontinued in the midway to the top edge 32a of the rising surface 32 and has the downstream end on the surface 2 so as to delay the flow rate of the water at the downstream of the drain ditch 12. The surface 2 is provided with a plurality of slopes 3 to 5 having different drainage directions such that the water is drained toward the drainage recess 6. The slopes 3 to 5 are tilted downward to the ridge lines 7 and 8 of the respective slopes. The water conducting groove part 21 is arranged in the vicinity of the downstream edge of the ridge lines 7 and 8. COPYRIGHT: (C)2013,JPO&INPIT |
