DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below.
This will be described in detail with reference to the drawings. 1 and 2 show an embodiment of a floor pan of a bathroom unit according to the present invention.

As shown in FIG. 1, the floor pan 1 includes a washing pan member 2 forming a washing floor and a bathtub pan member which forms a bathtub receiving portion and is arranged in connection with the washing pan member 2. 3 is provided. Washing pan member 2
A drain hole 21 is provided at the center in the longitudinal direction along the connecting portion with the bathtub pan member 3.

The bath pan member 3 has a main body 31 and two lids 33 for working holes 32 to be described later. Body 31
Is provided with two working holes 32 in the bottom surface 31a thereof, and a drain hole 34 for draining hot water or water drained from a bathtub into a bathtub receiving portion formed through a drain hole into a drain pipe. In addition, piping holes 35 for water supply piping and hot water supply are formed at both ends on the longitudinal side.

The floor pan 1 is constructed as described above, and is usually constructed as follows. As shown in FIG. 3, first, a support member 5 formed of a block, a frame, or the like is installed on a foundation FL in advance,
After adjusting the level to some extent, the worker descends on the foundation FL, and installs the washing pan member 2 on the installation portion.

Although not shown, an operator adjusts the level of the washing pan member 2 from the opening on the side of the bathtub receiver, or connects a drain pipe (not shown) to the drain hole 21 of the washing pan member 2. When the worker enters the working hole 32, the main body 3
After lifting the main body 31 of the bathtub pan member 3 by holding the peripheral portion of 1 by hand and descending on the foundation FL, as shown in FIG.
The main body 31 is installed on the support member 5 so as to be connected to the bathtub pan member 3, and the tip of the hot water supply or water supply pipe rising from under the floor is projected from the pipe hole 35 onto the main body 31.

After connecting the drainage pipe from above the working hole 32 to the draining hole 34 and adjusting the level of the main body 31, the working hole 32 is closed with the lid 33. The unused piping holes 35 are closed with a lid 36 in a watertight manner, and the piping holes 35 through which the piping has passed are sealed via a sealing material (not shown) such as rubber packing.

Although not shown on the floor pan 1 thus installed on the support member 5 which is an installation portion,
A bathroom unit is completed by assembling and installing a bathtub, a wall panel, a door frame, a ceiling panel, and the like by a known method.

As described above, the floor pan 1 is formed by connecting and assembling the washing pan member 2 and the bathtub pan member 3, so that
If the washing pan member 2 is set at a predetermined installation position, the level adjustment of the washing pan member 2 side is performed from the installation side of the bath tub pan member 3 in the still open state to the lower side of the washing pan member 2. To easily adjust the level of the bathtub pan member 3 and connect a drain pipe or the like to the bathtub pan member. Further, since the bathtub pan member 3 has the work hole 32 in the main body 31, even if the main body is installed in the installation portion, the work such as level adjustment and piping of the bathtub pan member 3 can be performed through the work hole 32. It can be carried out.

Moreover, if the operator passes the body through the working hole of the main body 31, the operator can carry the body by holding the peripheral portion of the main body 31.
It is easy to install the bathtub pan member 3 in the installation section. Furthermore, the bathtub pan member 3 in which the working hole 32 is invisible to the bather.
Because it is provided on the side, the appearance in the bathroom is good.

In addition, even if the piping under the floor becomes defective after construction, the bathtub is removed from the bathtub receiving portion and the cover 3 is removed.
By opening the work hole 32 to open the work hole 32, a repair work or the like can be performed through the work hole 32. That is, repair work can be easily performed without removing a wall panel, a ceiling panel, and the like as in the related art.

The floor pan of the bathroom unit according to the present invention comprises:
It is not limited to the above embodiment. For example, in the above-described embodiment, two working holes 32 are provided.
Or three or more. In the above-described embodiment, the piping holes are formed at both ends in the longitudinal direction of the main body 31. However, the piping holes may be omitted.

Incidentally, even in the case of a floor pan in which the washing floor and the bathtub receiving part are integrally formed, if a working hole is formed in the bathtub receiving part, the level from the working hole to the washing floor part side can be obtained. Adjustments and plumbing can be performed to some extent, and the bathroom can also be finished to look good.

[0020]

The floor pan of the bathroom unit according to the present invention is constructed as described above, and is easy to construct.
Even if problems such as poor piping under the floor occur after construction, in a short time,
In addition, repair work and the like can be performed at low cost.

In particular, according to the floor bread of claim 2,
There is no body, lid and seam on the floor of the washing area and it looks good. According to the floor pan of the third aspect, it is possible to more easily install the washing pan member or the bathtub pan member on the installation portion.
