  As shown in FIGS. 1 and 2, the bathtub 10 is a Western-style boat-shaped bathtub, and a tank body 11, projects outward from the upper edge of the tank body 11, and has a flange portion 12 that circulates around the tank body 11. , And four leg portions 13 projecting downward from the bottom surface of the tank body 11. The leg portion 13 has a substantially rectangular parallelepiped box shape, and a work opening 13a for nut tightening work is provided on a side surface thereof. An insertion hole 13 b (FIG. 2) for the bolt 14 is provided on the bottom surface of the leg portion 13.

  With the bathtub 10 turned upside down, the bolt 14 is inserted into the insertion hole 13b, and the edge of the insertion hole 13b is tightened from above and below by the nuts 15 and 16 so that the projecting length of the bolt 14 is predetermined. Is fixed to the leg 13. The tightening operation of the nuts 15 and 16 is extremely easy because the bathtub 10 is turned upside down.

  After fixing the bolt 14, the spacer 18 having the plate-like hole 18 a is attached to the bottom surface of the leg portion 13 with an adhesive or an adhesive.

  In this embodiment, the spacer 18 is made of hard rubber. Note that an adhesive layer covered with release paper may be provided on one side of the spacer 18, and the release paper may be peeled off to adhere the spacer 18 to the bottom surface of the leg portion 13.

  After attaching the bolts 14 and the spacers 18 in this way, the bathtub 10 is turned over so that it faces upward, and is installed on the waterproof pan 20.

  As shown in FIG. 3, in this embodiment, a waterproofing pan for bathrooms is configured by connecting a washing-side waterproof pan 25 to a bathtub-side waterproof pan 20. The bathtub-side waterproof pan 20 is provided with a drainage trap 27, and the washing area-side waterproof pan 25 is provided with a drainage trap 26. These drain traps 27 and 26 are disposed on the seam side of the waterproof pans 20 and 25 and on the drain outlet side (foot side) of the bathtub 10. A drainage gradient is provided at least in the bathtub installation area of the waterproof pan 20. In this embodiment, the waterproof pans 20 and 25 are provided with a drainage gradient so as to have a downward slope toward the drainage traps 27 and 26.

  Four recesses 21 corresponding to the four legs 13 are provided on the bottom surface of the FRP waterproof pan body 20 </ b> A of the bathtub-side waterproof pan 20. A tile pasting base plate 22 is pasted on at least the bathtub installation region on the waterproof pan body 20 </ b> A, and the tile 23 is pasted on the base pan 22. In the base plate 22 and the tile 23, openings 22 a and 23 a are perforated at positions overlapping with the recesses 21. Each opening 22a, 23a has an opening area smaller than that of the upper surface opening of the recess 21, and the edge of each opening 22a, 23a constitutes an overhanging portion that protrudes above the recess 21.

  As shown in FIG. 5, the adhesive 30 is poured into the recess 21. At this time, it is preferable to inject the adhesive 30 in a slightly small amount so that the adhesive 30 does not overflow from the opening 23a even if the bolt 14 is inserted later.

  Thereafter, the bathtub 10 to which the bolts 14 and the spacers 18 are attached as described above is placed on the waterproof pan 20, and at this time, the bolts 14 are inserted into the recesses 21 through the openings 23 a and 22 a, Embedded in the adhesive 30. The lower end surface of the bolt 14 is slightly separated from the bottom surface of the recess 21.

  In this embodiment, the outer peripheral edge of the spacer 18 overlaps the edge of the opening 23a of the tile 23 over the entire periphery. The inner hole 18 a of the spacer 18 is only slightly larger than the nut 15. For this reason, the spacer 18 covers the upper surface of the adhesive 30.

  When the adhesive 30 is cured, a bathtub installation structure in which the bathtub 10 is fixed to the waterproof pan 20 is obtained.

  In this bathtub installation structure, since the edges of the openings 23a and 22a of the tile 23 and the base plate 22 protrude above the concave portion 21, the cured body of the adhesive 30 does not come out upward. For this reason, the bathtub 10 is firmly fixed not only in the horizontal direction but also in the vertical direction.

  Further, in this embodiment, the leg portion 13 is mounted on the tile 23 via the spacer 18. Accordingly, the top surface of the bathtub flange portion 12 is made to be horizontal with high accuracy by attaching spacers 18 of appropriate thicknesses to the three leg portions 13 except the four or one on the most water side. Can do.

  In other words, the upper surface of the waterproof pan 20 is provided with a drainage gradient so as to be downwardly inclined toward the drain trap 27 of FIG. 3, and the closer to the drain trap 27, the lower the level is.

  Accordingly, the thickness of the spacer 18 attached to the leg portion 13 closer to the drain trap 27 is increased, and the upper surfaces of the spacers 18 that overlap the edge of the tile opening 23a of each recess 21 are at the same level. By selecting the thickness of the spacer 18 so that the flange portion 11 of the bathtub 10 becomes horizontal.

  Since both the FRP bathtub 10 and the waterproof pan body 20A have high dimensional accuracy, the flange portion 11 can be made horizontal by setting the thickness of the spacer 18 to the design value calculated from the drainage gradient and the leg position. It becomes.

  When the spacers 18 are attached only to the three legs below the water, the legs 13 arranged on the most upstream side (water side) of the drainage gradient are directly on the tiles 23 without the spacers 18 interposed. Placed on.

  In this embodiment, since the spacer 18 is made of rubber and covers the adhesive 30, water does not splash on the adhesive 30, and deterioration of the adhesive 30 due to water is prevented. In addition, since the spacer 18 is made of rubber, an anti-vibration effect is also achieved.

  The illustrated embodiment is an example of the present invention, and the present invention may take forms other than those illustrated. For example, the spacer 18 may be made of a soft resin instead of rubber. Further, only the surface that contacts the tile of the spacer may be made of rubber or soft resin.
