Further, as shown in FIG. 5, the bathtub leg opening 3a is set at the bottom 1c of the bathtub so that the bathtub leg 3b does not ride on the bathtub receiving opening 1a.
Since it is not necessary to support it, it is very advantageous in strength. Naturally, drainage pipe connection, level adjustment of the waterproof floor support leg 4a, fixing of the leg with the lock nut 4b, and adhesion between the building floor surface 13 and the waterproof floor support leg 4a can be performed from the bathtub receiver opening 1a.
Workability is also very good.

Further, by covering the bathtub receiving portion opening 1a with the lid 2, water tightness can be ensured. When the construction is completed, the bathtub 3 and the bathtub apron are covered, and the joint of the lid 2 is seen by the customer. There is no need to worry about the design without touching it.

In the second embodiment, as shown in FIGS. 4 and 5, the bathtub receiving portion opening 1a in the bottom surface 1c of the waterproof floor bathtub receiving portion of the first embodiment.
By flushing the lid 2 attached to the tub, the drainage accumulated in the bathtub receiving portion 1c can be smoothly drained to the bathtub receiving portion drain port 1d. In addition, when the gap between the bathtub bottom surface 3a and the lid 2 cannot be secured, it is effective in terms of fitting.

In a third aspect, as shown in FIGS. 6 and 7, when the bathtub receiving section drain port 1b and the washing place section drain port 1d are installed at the center so as to be symmetrical to the waterproof floor 1, the bathtub receiving section opening 1a. Similarly, if the waterproof floor 1 is arranged so as to be symmetrical, the R / L of the mold and the product does not occur, so that the mold cost and the stock load of the product are reduced, so that the efficiency and efficiency are extremely high. One is economical.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a waterproof floor 1 according to the present invention and its structure will be described in detail with reference to FIGS. The waterproof floor 1 shown in FIG. 1 is provided with a bathtub receiving portion opening 1a through which a human can enter and exit at the bathtub receiving portion bottom surface 1c at the time of molding, so that a building wall surface 12 surrounding the bathroom is covered in three directions as shown in FIG. Even at a construction site, the worker 11 can enter the bathtub receiving opening 1a and dodge the body, so that the installation work of the waterproof floor 1 can be performed easily and quickly.

FIG. 4 shows a state in which the cover 2 is attached by lowering the bathtub receiving section 1c one step in a stepwise manner.
This is effective when the clearance between the bathtub bottom surface 3a and the lid 2 cannot be sufficiently secured. Also, when draining to the bathtub receiving section drain port 1b, the shape is such that residual water hardly remains.

In FIG. 5, since the bathtub receiving portion opening 1a is provided at a position where the bathtub leg 3b and the cover 2 do not overlap, an excessive load is not applied to the cover 2, so that only watertightness needs to be considered.

FIGS. 6 and 7 show that the bathtub receptacle opening 1a and the washing basin drainage port 1d are installed at the center so that they are symmetrical to the waterproof floor 1. By arranging them in a symmetrical shape, R / L of the mold and the product does not occur, so that the cost of the mold and the reduction of the inventory load of the product are very efficient and economical.

[0014]

According to the present invention, the following effects are exhibited by the above configuration. According to the first aspect, the washing section having the washing section drainage port 1d on the bottom section 1f of the washing section and the bathtub receiving section having the bathtub side drain port 1b on the bottom surface 1c inside the bathtub receiving section formed adjacently via the partition wall 1g are integrally formed. In the waterproof floor 1, the bathtub receiving portion opening 1a through which a person can enter and leave is formed in the bathtub receiving portion bottom surface 1c. The body can be dodged by the part 1a, and the construction can be performed efficiently and quickly. Watertightness is ensured by covering the opening 1a with a lid 2 formed separately. Of course, since it is integrally formed, the cost is lower than that of the waterproof floor formed by division, and the workability such as the connection work of the divided portion and the level adjustment of the waterproof floor is excellent.

The second aspect is effective when the bathtub receiving portion opening 1a and the lid 2 are flush with each other so that the clearance between the bathtub bottom surface 3a and the lid 2 cannot be sufficiently secured. Further, the drainage also smoothly flows to the bathtub drainage port 1b without any level difference, so that water cannot be collected.

According to the third aspect, since the bathtub receiving portion opening 1a is provided so as to be symmetrical with respect to the waterproof floor 1, the R / L of the mold and the product does not occur.
