BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. FIG. 1 is a cross-sectional view showing an embodiment of a waterproof sheet structure according to the present invention, and the same components as those in FIGS. 4, 5, and 6 are denoted by the same reference numerals and description thereof is omitted. In FIG. 1, a baseboard base material 20 is attached to an inner side surface 2x of the mounting portion 2 of the wall panel, and the surface of the baseboard base material 20 is the same vertical surface as the surface 9x of one rising piece 9a of the liner 9. The baseboard surface 21 is formed as a surface. That is, the skirting base material 20 is adhered to the surface 2x using an adhesive, so that the rising piece 9a having a folded portion is provided.
Is filled up, the surface 9x of the rising piece 9a rises in the same plane as the surface of the baseboard base material 20 to form the baseboard base 21.

An outer skirting board base material 22 is adhered to the skirting board base surface 21 provided on the upper side of the rising piece 9a with an adhesive. The base material 22 covers the upper part of the rising piece 9a. The surface of the rising piece 9a located under the base material 22 is covered with an interposition material 23 such as a steel plate. I have. The rising portion 14 of the waterproof sheet 13 is bonded to the surface of the interposer 23 with an adhesive.
In this case, the thickness of the baseboard base material 22 is set to be larger than the sum of the thicknesses of the above-described interposition material 23 and the rising portion 14. Therefore, the surface of the baseboard base material 22 is located outside the surface of the rising portion 14.

The surface of the baseboard base material 22 has an inner baseboard 2
4 are bonded by an adhesive, and
The outer skirting board 25 is adhered to the surface of the base 4. These two baseboards 2
The baseboard 26 is constituted by 4 and 25. The inner skirting board is made of, for example, stainless steel having a thickness of about 1 mm, and its lower end 24a is grounded to the surface of the waterproof sheet 13 so that a gap 27 is formed between the inner surface and the surface of the rising portion 14. The outer skirting board 25 has a lower end 25a slightly raised from the waterproof sheet 13 side. The outer skirting board 25 is made of, for example, about 1.2 mm of stainless steel.

A surface material 33 such as a long vinyl chloride sheet is adhered to the front side of the waterproof sheet 13 with an adhesive or the like.

According to the present embodiment, the gap 27 is formed between the rising portion 14 of the waterproof sheet and the baseboard 26. Therefore, even if the rising portion 14 has undulation, the gap 27 is formed. Since this can be absorbed, the skirting board 26 attached to the skirting board base material 22 can be held flat.

Further, according to the present embodiment, the skirting board 26 is formed by the inner skirting board 24 and the outer skirting board 25, and the lower end 24a of the inner skirting board 24 is grounded on the waterproof sheet 13. The disadvantage that the rising portion 14 is viewed from the inside and the appearance is deteriorated can be eliminated.

Further, since the interposition material 23 is provided between the rising portion 14 and the rising piece 9a of the liner 9, even if the liner 9 is formed of stainless steel, for example, the rising portion 14 is formed.
Is difficult to adhere to stainless steel,
4 can be solved without the problem that it peels off after many months.

Embodiment 2 FIG. FIG. 2 shows another embodiment of the seat waterproofing structure according to the present invention, in which the same components as those in FIG.

In FIG. 2, the interposition material 23 is the floor slab surface 1
It rises from the side and extends further upward beyond the rising piece 9a of the liner 9. In this case, the baseboard base 22 has a relatively short length. The rising portion 14A is adhered to the surface of the interposition material 23 with an adhesive. The rising portion 14A is L-shaped, and a horizontal piece 14A at the lower end thereof is adhered on the waterproof sheet 13.
In this case, the thickness of the baseboard base 20 is set to be larger than the sum of the thicknesses of the interposer 23 and the rising portion 14A.
Thus, the skirting board 26 made of one piece of stainless steel adhered to the surface of the skirting board base 20 with an adhesive has a gap 27 and covers almost the upper half of the rising portion 14A.

A relatively thick mortar 29 is applied to the front side of the waterproof sheet 13, and a tile 30 is attached to the front side of the mortar 29. The outer periphery of the tile 30 is filled with a joint material 32.

According to such a configuration, the undulation of the unevenness generated on the surface of the rising portion 14A can be absorbed by the gap 27, and the portion of the skirting board 26 covering the rising portion 14A is formed into a vertical flat shape. Can be kept. Further, since the waterproof sheet 13 is covered with the mortar 29, the water resistance of the floor can be improved. In addition, since the interposer 23 is used also in the present embodiment, even when the liner 9 is formed of stainless steel, the rising portion 14a of the waterproof sheet can be bonded well.

Embodiment 3 FIG. 3 is a sectional view showing another embodiment of the waterproof sheet structure according to the present invention.
The same components as those in FIG. 2 are denoted by the same reference numerals.

In this case, the difference from FIG. 2 is that a mortar 29 is covered with a stone material 31, and the other configuration is the same as that of FIG. Thus, even when the stone material 31 is used, the same effect as in FIG. 2 can be obtained. The mortars 29 and 30 as shown in FIG. 2 and the mortar 2 as shown in FIG.
