PURPOSE:To promote the effect of heat insulation of a floor and to improve execution and connection work efficiency of a drain pipe by providing a waterproof pan on a lower waterproof pan to make a double floor, and boring holes in the lower waterproof pan to carry out height adjustment, piping execution and connection work. CONSTITUTION:A bearing body 56 connecting a frame 58 in the shape of a frame is mounted on a first waterproof pan 10. After that, the lower surface of a second waterproof pan 30 is borne on a first bearing section 60 thereof, and the lower surface of a drain gutter 32 is borne on a second bearing section 62. At that time, adjust bolts 68 are loaded on the frame 58. The second waterproof pan 30 is provided on the first waterproof pan 10 to make a double floor. At that time, the first waterproof pan 10 is not exposed on the outside, so that holes are bored in the pan 10 to carry out the operation of the bolts 68 and the execution and connection work of pipes. The upper surface of the pan 30 has the same height as that of a flange 20 of a bath-tub 18. According to the constitution, the effect of heat insulation of a floor is promoted, at the same time, the execution efficiency of the waterproof pan is promoted, and a bather can easily enter the bath tub 18. |
