DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof pan structure for a bathroom unit or the like.

[0002]

2. Description of the Related Art In general, as shown in FIG. 5, a bathroom unit 10 includes an adjacent floor pan 111 used as a washing place and a waterproof pan 11 formed with a bathtub installation part 112,
A bathtub 12 installed in a bathtub mounting portion 112 of the waterproof pan 11, and a wall panel 13 erected on the periphery of the waterproof pan 11 and surrounding the waterproof pan 11 and the bathtub 12.
And a ceiling panel (not shown) that covers an upper opening formed by these wall panels 13.

[0003] The waterproof pan 11 constituting such a bathroom unit 10 is difficult to mold, has a large weight, and is large in size, since the adjacent floor pan 111 and the bathtub mounting portion 112 are integrally formed as described above. In addition to requiring a large amount of labor to carry into the space, there is a problem in that when installing on the floor surface, it is difficult to adjust the level and adjust the position of the pipe connection, resulting in poor workability.

[0004] For this reason, as described in Japanese Utility Model Publication No. 6-19658, it is proposed that the adjacent floor pan and the bathtub installation part are separately formed, and both are connected on site to form a waterproof pan. Have been. That is, the engaging recess is formed at the edge of the connection portion with the adjacent floor pan in the bathtub installation portion, while the engagement piece is formed at the edge of the connection portion with the bathtub installation portion in the adjacent floor pan, and the bathtub is installed on the floor base. After attaching the part, the engaging recess is filled with a low-viscosity sealing material, and when the adjacent floor pan is installed on the floor base, the engaging piece is inserted into the engaging recess of the bathtub installation part, that is, the sealing material. By doing so, the connection between the two is sealed.

[0005]

However, the waterproof pan, that is, the adjoining floor pan and the bath tub mounting part are usually made of FR.
Although it is molded with P, FRP cannot be molded with a very small radius of curvature, so the width of the above-mentioned engaging recess has to be relatively large, and a sealing material for sealingly connecting the wall panel is required. Large amounts of sealing materials of different viscosities are required. Similarly, the vicinity of the drain outlet is also sealed and connected.However, mold is likely to be generated on the sealing material because it is constantly moist, and if the drain cover is removed at the time of cleaning, the mold is exposed. There was a problem that it was unsightly.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is intended to securely seal an adjacent floor pan and a bathtub installation pan formed separately from each other by using a small amount of a sealing material, and to seal the same. It is an object of the present invention to provide a waterproof pan structure in which parts can be connected invisibly.

[0007]

According to the present invention, a bathtub installation pan for installing a bathtub and an adjacent floor pan are formed separately, and the bathtub installation pan and the adjacent floor pan are connected to each other. In the waterproof pan, the embankment-shaped wall is formed by rising from the floor surface of the adjacent floor pan at the edge of the bath tub-installed pan on the washing area side, and a part of the embankment-shaped wall is dropped to open a drain port. A drainage space that has a drainage space that can be fitted to the dike-like wall of the bathtub installation pan and the drainage space, and a drainage hole that is open at the edge of the adjacent floor pan on the bathtub side. It is formed that the embankment-like wall and the drainage space of the adjacent floor pan are respectively fitted via the sealing material applied around the drainage wall of the bathtub installation pan and around the drainage port of the drainage space. Feature Than it is.

[0008]

[Function] A sealing material is applied to the upper surface of the dike-like wall of the bathtub installation pan and around the drainage port of the drainage space, and the dike-like wall of the adjacent floor pan separately formed on the dike-like wall and the drainage space. By fitting the drainage space and the drainage space, they are connected while being sealed, forming a waterproof pan.

As a result, the bath tub installation pan and the adjacent floor pan are securely sealed with a small amount of the sealing material, and the sealing material including the drain port can be connected with good appearance without being noticeable.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a waterproof pan 1 of the present invention. As shown in FIG. 2, the waterproof pan 1 has a bathtub installation pan 2 and a bathtub pan 2 which are separately formed by an FRP press method or the like. It is formed by connecting adjacent floor pans 3.

The bathtub installation pan 2 has an embankment-like wall 21 raised from the floor surface of the adjacent floor pan 3 at one side edge serving as a connection portion with the adjacent floor pan 3. A drainage space 22 is formed in which a substantially central portion of the bank-like wall 21 is depressed to open a drainage port 22a.

On the other hand, the adjacent floor pan 3 is provided with an embankment which can be fitted to the embankment-shaped wall 21 and the drainage space 22 of the above-described bathtub installation pan 2 at one side edge serving as a connection portion with the bathtub installation pan 2. A drainage space 32 having an opening in the shape of a wall 31 and a drainage port 32a is formed.

A horizontal portion 23 for erection of a wall panel is provided on the periphery of the bathtub installation pan 2 and the adjacent floor pan 3 except for one side serving as a connection portion with the other pan. , 33 are formed following the drainage rising walls 24, 34.

In order to form the waterproof pan 1 by connecting such a bathtub installation pan 2 and an adjacent floor pan 3, first,
After fixing the bathtub installation pan 2 to the floor base (not shown),
A sealing material S (see FIG. 3) having a viscosity that does not drop down, for example, a silicon sealing material, is applied to the upper surface of the bank-like wall 21 and the periphery of the drainage port 22a of the drainage space 22. Next, the adjacent floor pan 3 is fixed to the floor substrate adjacent to the bathtub installation pan 2. At this time, the embankment-shaped wall 31 and the drainage space 32 of the adjacent floor pan 3 are fitted to the embankment-shaped wall 21 and the drainage space 22 of the bathtub installation pan 2. And
Drain port 22a of bathtub installation pan 2 and adjacent floor pan 3
As shown in FIG. 4, the U packing 4
After mounting, the drain traps 5 and 6 are screwed and clamped from the front side and the back side to form a drain port.

As a result, the bath pan installation pan 2 and the adjacent floor pan 3 are connected to each other while being sealed via the sealing material S, and the waterproof pan 1 is formed. In this case, a sealing material having a special viscosity is not required, and can be used as a sealing material for sealingly connecting the wall panel. In addition, the amount of the used sealing material can be securely sealed by applying a normal linear shape. Further, the hermetically connected portion of the bathtub installation pan 2 and the adjacent floor pan 3 becomes a back surface of the overlapped portion including the periphery of the drainage port, so that the connection can be made invisibly and easily and visually.

It is to be noted that the bathtub installation pan 2 in this embodiment can be used as a bathtub fitting mounting body having an opening for fitting and mounting the bathtub.
