  As shown in FIG. 9, a receiving portion 71 b below the door frame 71 is received in the receiving groove 22 a of the receiving member 20 for the bathroom door 70.

The washroom floor panel 3 is produced as follows and is further installed in the bathroom 1.
The constituent members of the washroom floor panel 3 are respectively produced. The panel body 11 can be produced by foam molding. The upper and lower panel members 12 and 13 can be manufactured by sheet metal processing or the like.
The laminated body in which the reinforcing panel members 12 and 13 are stacked on the upper and lower sides of the panel main body 11 is set, for example, in a vacuum pressure air heat press (not shown). For example, a thermosetting urethane adhesive is applied between the panel body 11 and the reinforcing panel members 12 and 13. While heating the said laminated body with the said vacuum pressure air-heat press, the said laminated body is compressed to the thickness direction with an air pressure and a vacuum pressure. Thereby, the panel main body 11 and the reinforcing panel members 12 and 13 are joined.

Separately, the receiving member 20 is produced by two-color extrusion molding.
The adhesive 4 is filled in the adhesive recesses 11b and 11c of the receiving member installation portion 11e in the panel body 11 after being joined to the reinforcing panel members 12 and 13, respectively.
Then, the receiving member 20 is installed in the receiving member installation part 11e. The receiving member 20 is fixed to the panel body 11 via the adhesive 4.

Further, the drain port member 16 is attached to the panel body 11.
Thereafter, the surface layer sheet 14 is attached to the upper surface of the upper reinforcing panel member 12. At this time, the protruding recess 23b is filled with a protruding piece sealing material 33 such as silicone. In addition, the end portion of the surface layer sheet 14 is covered with the protruding piece portion 23. Thereby, the overhanging piece sealing material 33 is brought into close contact with the surface layer sheet 14, and a sealing property between the overhanging piece portion 23 and the receiving member 20 and the surface layer sheet 14 can be secured.

  According to the washing floor panel 3, the panel body 11 made of foamed resin is sandwiched by sandwiching the upper and lower reinforcing panel members 12 and 13, so that it can be manufactured at low cost. The strength of the washroom floor panel 3 can be ensured. Furthermore, the expansion and contraction of the panel body 11 due to temperature change can be suppressed by restraining the foamed resin panel body 11 by the upper and lower reinforcing panel members 12 and 13.

At the construction site of the bathroom 1, the washing floor panel 3 is installed at the bottom of the washing place 1b. A bathroom wall 60 and a bathroom door 70 are connected to the outer ends of the three sides of the washing floor panel 3.
Prior to installing the wall panel 61 of the bathroom wall 60, a groove bottom sealing material 32 such as silicone is provided at the bottom of the receiving groove 22a (FIG. 6B). The groove bottom sealing material 32 may be filled in the groove bottom recess 22d. Therefore, it is possible to prevent the application amount of the groove bottom sealing material 32 from varying for each worker on site, and to stabilize the construction quality.

Next, as shown in FIGS. 7 to 8, the receiving portion 61b at the lower end of the wall panel 61 is fitted into the receiving groove 22a. Specifically, for example, as shown in FIG. 7A, the wall panel 61 is inclined and the receiving portion 61b is inserted into the receiving groove 22a. At this time, when the seal protrusion 31 is caught by the receiving part 61b, the first seal protrusion 31a is deformed to be pushed downward.
As shown in FIG. 7B, the wall panel 61 is gradually raised while the receiving portion 61b is inserted into the receiving groove 22a. Accordingly, the seal protrusion 31 is deformed so as to rotate around the groove edge 22c.

As shown in FIG. 8A, when the wall panel 61 is erected, the first seal projecting piece 31a is sandwiched between the washing wall inner wall 22b of the receiving groove 22a and the wall panel 61 and compressed. The second seal protrusion 31 b is pressed against the side surface of the wall panel 61. Thereby, the space between the wall panel 61 and the receiving member 20 can be sealed. Since it is not necessary to install a sealing material on the washing wall inner wall 22b at the construction site of the bathroom 1, not only can the construction be simplified, but also the construction quality can be prevented from being varied by the operator.
Further, the receiving portion 61 b of the wall panel 61 is landed on the groove bottom surface 22 f and is in close contact with the groove bottom seal material 32. Thereby, the space between the wall panel 61 and the receiving member 20 can be more reliably sealed.

Next, as shown by the white arrow in FIG. 8A, the attachment piece 43 of the joint member 40 is inserted between the end of the surface layer sheet 14 and the wall panel 61.
And as shown in FIG.8 (b), the joint member 40 is fixed with respect to the receiving member 20 by engaging the engaging part 45 with the engagement receiving part 25a. Since the joint member 40 can be accurately positioned with respect to the receiving member 20 by the engagement between the engaging portion 45 and the engagement receiving portion 25a, it is possible to prevent the construction quality from being varied by the operator.
By installing the joint member 40, the gap between the end portion of the surface layer sheet 14 and the wall panel 61 is covered by the front side piece portion 42. Therefore, the appearance at the corner between the wash floor panel 3 and the bathroom wall 60 can be improved.
Furthermore, the lower end portion of the attachment piece portion 43 of the joint member 40 is pressed against the second seal projection piece portion 31b, so that between the joint member 40 and the seal projection piece 31, and as a result, between the joint member 40 and the receiving member 20 The seal between them can be strengthened.

  As shown in FIG. 9, the receiving part 71 b of the door frame 71 is similarly attached to the corresponding receiving member 20. The space between the door frame 71 and the receiving member 20 can be sealed by the sealing protrusion 31 and the groove bottom sealing material 32. The joint member 40 can cover the gap between the end of the surface layer sheet 14 and the door frame 71.

The column member 62 of the bathroom wall 60 is connected to the side plate portion 13 b of the lower reinforcing panel member 13 via the connection fixing member 65. Thereby, the bathroom wall 60 and the washroom floor panel 3 can be firmly fixed. In addition, the load on the bathroom wall can be transmitted to the lower reinforcing panel member 13 via the connection fixing member 65.

Next, another embodiment of the present invention will be described. In the following embodiments, the same reference numerals are given to the drawings for the same configurations as those already described, and the description thereof is omitted.
Second Embodiment
10 and 11 show a second embodiment of the present invention.
As shown in FIG. 10, the receiving member 20 </ b> B of the second embodiment is an extrusion-molded product made only of hard resin, and does not have the soft resin sealing protrusion 31.
In the second embodiment, a sealant 51 such as a rubber packing is attached to the washing wall side inner wall 22b of the receiving groove 22a when the bathroom 1 is constructed on site. The sealing material 51 faces the receiving groove 22a.
When the receiving portion 61b of the wall panel 61 is fitted into the receiving groove 22a, the sealing material 51 is brought into close contact with the side surface of the wall panel 61, so that the space between the receiving member 20B and the wall panel 61 can be sealed.
Further, a joint material 52 made of silicone is filled between the end portion of the surface layer sheet 14 and the receiving portion 61b instead of the joint member 40 made of a resin molded body. As a result, the gap between the surface layer sheet 14 and the wall panel 61 can be hidden by the joint material 52. In addition, since the joint material 52 is in close contact with the side surface of the wall panel 61, the sealing performance can be further enhanced.

Similarly, as shown in FIG. 11, when the receiving portion 71b of the door frame 71 is fitted into the receiving groove 22a, the sealing material 51 is brought into close contact with the door frame 71, and the space between the receiving member 20B and the door frame 71 is sealed. it can.
Further, by filling the joint material 52 between the end of the surface layer sheet 14 and the door frame 71, not only can the gap between the surface layer sheet 14 and the door frame 71 be hidden, but the joint material 52 can be used as a door. By being in close contact with the frame 71, the sealing performance can be further enhanced.

<Third Embodiment>
12 to 14 show a third embodiment of the present invention.
As shown in FIG. 12, in the third embodiment, the upper surface of the protruding piece portion 23 of the receiving member 20C is flat, and the protruding recess 23b (FIG. 6B) is not formed. The overhanging piece portion 23 and the surface layer sheet 14 are joined by a waterproof double-sided adhesive tape 35 instead of the sealing material 33 (FIG. 6B). As the waterproof double-sided adhesive tape 35, for example, an acrylic adhesive tape such as an acrylic foam structure joining tape is used.

Further, a joint material 53 made of silicone caulking or the like is filled between the convex wall portion 25 and the end face of the surface layer sheet 14 in the receiving member 20C.
The double-sided adhesive tape 35 and the joint material 53 are double waterproofed between the end portion of the surface layer sheet 14 and the receiving member 20 </ b> C.
The joint material 53 is exposed to the outside when the joint member 40 is not attached. Therefore, the construction state of the joint material 53 and the sealing state between the receiving member 20C and the surface layer sheet 14 can be easily checked.

As shown in FIG. 13, the joint material 53 is covered by the front side piece 42 of the joint member 40 when the joint member 40 is attached.
In addition, as shown in FIG. 12, the front-side piece part 42 in the natural state (when not attached) has a tip slightly hanging downward. As shown in FIG. 13, when the joint member 40 is mounted between the surface layer sheet 14 and the wall panel 61, the front side piece 42 is pushed up by the surface layer sheet 14 and the drooping is corrected. Thereby, the front side piece 42 can be pressed against the upper surface of the surface layer sheet 14 to be brought into close contact therewith.

  A projecting portion 23 d is formed on the lower surface of the protruding piece portion 23. The convex portion 23d enters the adhesive concave portion 11b and is buried in the adhesive 4b.

  A convex portion 22g is formed on the lower surface of the receiving portion 22 in the receiving member 20C. The convex portion 22g enters the adhesive concave portion 11c and is buried in the adhesive 4c.

As shown in FIG. 12, the groove bottom concave portion 22d of the receiving portion 22 is disposed so as to be biased to the portion of the groove bottom surface 22f on the washing place 1b side (left side in FIG. 12).
As shown in FIG. 13, filling of the groove bottom sealing material 32 (FIG. 6B) is omitted in the groove bottom concave portion 22 d of the receiving portion 22 that receives the wall panel 61. Therefore, the receiving member 20 </ b> C is not bonded to the wall panel 61.
For this reason, the wall panel 61 can be easily separated from the receiving member 20 </ b> C and thus the wash floor panel 3 at the time of renovation, for example. Alternatively, the receiving member 20 </ b> C can be prevented from sticking to the wall panel 61 and coming off from the panel body 11.

  As shown in FIG. 14, the groove bottom recess 22d of the receiving portion 22 that receives the lower frame 71 of the bathroom door 70 is filled with a groove bottom sealing material 32 made of an adhesive such as silicone. As a result, the receiving portion 71 b of the lower frame 71 is bonded to the receiving member 20 </ b> C via the groove bottom sealing material 32. As a result, even when the lower frame 71 is stepped on and deformed, the firmly joined state between the lower frame 71 and the receiving member 20C can be maintained.

The present invention is not limited to the embodiment described above, and various modifications can be made without departing from the spirit of the invention.
For example, in the first embodiment, instead of the joint member 40, the joint material 52 may be filled between the end portion of the surface layer sheet 14 and the receiving portions 61b and 71b.
The wash floor panel 3 may include a bathtub pan provided on the lower side of the bathtub 1a. The bathtub pan may be separate from or integral with the wash floor panel 3.
The bathroom includes a shower room.

  The present invention is applicable, for example, to a bathroom floor.
