  The pressing member 50 is disposed below the horizontally extending portion of the waterproof pan cover 22b when the pressing plate 50b is disposed on the bathroom side with respect to the support screw 51. It is formed in the dimension which can oppose the inclined part. In the first embodiment, the pressing member 50 in which the support plate portion 50a, the pressing plate portion 50b, the inclined guide portion 50c, and the introduction guide portion 50d are integrally formed of metal is applied. Although not clearly shown in the figure, in the lower frame base 22 a of the lower frame 22, pressing members 50 having the same configuration are disposed at a plurality of places with an appropriate distance therebetween.

  As shown in FIG. 2 and FIG. 4, the vertical frame 23 of the frame 20 has an expected dimension equal to that of the lower frame 22 and has a vertical frame base 23 a having a rectangular cylindrical shape. The vertical frame base 23a has an estimated dimension substantially equal to the thickness of the side wall panel SW. The vertical frame base 23a is provided with a side cover 23b at an inner edge portion located on the undressing room side. The side cover portion 23 b is a portion linearly extending from the inner edge portion of the vertical frame base 23 a toward the undressing room. Reference numeral 23c in the figure is a fin portion provided on the side cover portion 23b for mounting the tight material 24 interposed between the longitudinal ribs 14A and 15B of the shoji 10A and 10B.

  When installing the frame 20 provided with the lower frame 22 and the vertical frame 23 configured as described above, as shown in FIGS. 4 and 5, the entire width of the frame 20 in advance, that is, the longitudinal dimension of the lower frame 22 And cut the vertical plate 32 of the waterproof pan 30 in a range substantially equal to the sum of the found dimensions of the left and right vertical frames 23, and flatten the lower inner surface of the entrance from the floor 40 of the undressing room to the waterproof pan 30 Keep it. Regarding the dimension for cutting the vertical plate portion 32, the height dimension H from the lower surface of the portion provided with the accommodation recess 33 in the waterproof pan 30 to the upper surface of the vertical plate portion 32 after cutting extends horizontally to the waterproof pan cover portion 22b. The distance D is set smaller than the dimension D between the existing portion and the upper surface of the pressing plate 50b (H = D-a).

  Next, the primary water blocking material 35 is disposed on the upper surface (water blocking surface) of the housing recess 33 so as to contact the step surface 34 of the floor plate portion 31 and the housing recess 33, and the cut end surface (water blocking surface) of the vertical plate portion 32 Place the secondary water blocking material 36 on the As the primary water blocking material 35 and the secondary water blocking material 36, in consideration of workability, it is preferable to be a dry material that does not require curing time, and has a plate thickness t larger than the above-mentioned distance a Apply. In particular, if the water stopping material disposed between the lower surface of the side wall panel SW and the receiving recess 33 is also used as the primary water stopping material 35 disposed on the upper surface of the receiving recess 33, as shown in FIG. A series of primary water stop lines can be constructed between the and the dressing room.

  Next, as shown in FIG. 5 and FIG. 6, the frame 20 is placed with the waterproof pan 30 in a state (non-contacting position) in which the pressing member 50 is disposed such that the pressing plate portion 50 b does not protrude to the bathroom side. It is arranged to bridge between the floor materials 40. In this state, the horizontally extending portions of the lower surface (water blocking surface) of the lower end bending portion 22e of the lower frame 22 and the waterproof pan cover portion 22b with respect to the water blocking members 35, 36 disposed in the waterproof pan 30. The lower surface (water-stopping surface) of the frame 20 abuts, and the self-weight of the frame 20 causes the waterproofing members 35 and 36 to abut against the lower frame 22 and the waterproof pan 30, respectively.

  Here, if the waterproof pan 30 and the lower frame 22 are formed with high accuracy and there is no deformation such as warpage, the waterproofing members 35 and 36 are waterproofed over the entire length of the lower frame 22 only by the weight of the frame 20 alone. With the pan 30 and the lower frame 22 in contact with each other, there is no possibility that the water in the bathroom leaks from the gap between the waterproof pan 30 and the lower frame 22 to the outside. However, the influence of deformation such as molding error and warping of the waterproof pan 30 and the lower frame 22 can not actually be eliminated, and the waterproofing members 35 and 36 are waterproofed over the entire length of the lower frame 22 only with the weight of the frame 20 alone. It is difficult to abut the pan 30 and the lower frame 22 continuously.

  Therefore, in the first embodiment, the pressing member 50 is rotated from the state shown in FIG. 7A, and as shown in FIG. 7B, the pressing plate portion 50b is in contact with the lower surface of the waterproof pan 30. I am trying to As described above, as the water blocking material 35, 36, one having a plate thickness t larger than the distance a is applied. Therefore, when the pressing member 50 is brought into contact with the lower surface of the waterproof pan 30, as shown in FIG. 3, the water blocking members 35, 36 disposed between the waterproof pan 30 and the lower frame 22 are crushed. Thus, the water in the bathroom is prevented from leaking out through the gap between the waterproof pan 30 and the lower frame 22.

  Moreover, in the pressing member 50, the introduction guide portion 50d and the inclined guide portion 50c are provided on both sides of the pressing plate portion 50b. Therefore, when the pressing plate portion 50b is moved to the contact position projecting to the bathroom side, the tilting action of the tilting guide portion 50c can be utilized regardless of the direction in which the pressing plate portion 50b is rotated, The pressing plate portion 50b can be brought into contact with the lower surface of the waterproof pan 30 without requiring an operating force.

  After that, screw the screw S to the floor material 40 through the floor material cover portion 22c of the lower frame 22 and screw the screw S to the side wall panel SW through the vertical frame 23 to obtain the bathroom and the undressing room It is possible to attach the frame 20 in a state in which the primary water stopping line with the primary water stopping material 35 and the secondary water stopping line with the secondary water stopping material 36 are secured between them.

  In the first embodiment described above, the mounting structure of the bathroom fitting for mounting the bathroom including the waterproof pan 30 having the housing recess 33 between the floor plate portion 31 and the vertical plate portion 32 is exemplified.
