Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a bath unit comprising a box-shaped house structure and a bathroom core built into the house structure.

(Prior Art) Conventionally, when installing a bathroom core having a washing area and a bathtub, concrete is poured on the ground to form a uniform surface, blocks are stacked on this concrete surface, and blocks are stacked on top of the blocks. The washing area and bathtub were mounted and supported via a height adjustment jig.

However, the above configuration requires concrete pouring work over a relatively wide area, resulting in low workability at a construction site. Placing concrete requires a curing period, and the workers are plasterers who are different from the carpenters who install the bathroom cores, so the work efficiency is extremely low.

Therefore, Special Publication No. 55-8163 and Utility Publication No. 56-29425
As shown in the publication, a construction method has been developed in which the bathroom core is supported in a floating state by supporting the lower surfaces of the washing area and bathtub portion of the bathroom core with hanging members. However, this construction method had problems with support strength because the entire bathroom core was suspended over a relatively large area.

In addition, when installing a bathroom core in the house structure,
Since the bathroom core was installed on the floor of the house structure, the bathtub was located at a high position, and had a high straddling height from the washing area.

(Purpose of the invention) This invention was made based on the above circumstances, and its purpose is to provide a bathroom that is easy to install, can reliably support the bathroom core, and can reduce the height of the transition from the washing area to the bathtub. The aim is to provide units.

(Summary of the invention) The gist of the invention is to include a substantially box-shaped house structure and a bathroom core built into the house structure,
The bathroom core has a washing area and a bathtub that protrudes below the washing area, and the house structure has a floor plate on the bottom of which supports the washing area of the bathroom core, and the bathtub. The bath unit is characterized by having an opening for inserting the body.

(Structure of the invention) An embodiment of the invention will be described below with reference to FIGS. 1 to 3.

In the figure, 1 is a bath unit, and this bath unit 1 is supported by being placed on a concrete cloth foundation 2 built on the ground A. Four concrete supports 3 are erected within the cloth foundation 2.

The bath unit 1 is preassembled in a factory and includes a box-shaped house structure 10 and a bathroom core 30 that is incorporated into the house structure 10. A detached house is constructed by transporting this bath unit 1 together with other box-shaped house components to a construction site and connecting them together. Additionally, this bath unit can be connected to an existing house to extend or remodel the bath.

The house structure 10 is assembled by a so-called two-by-four construction method, and includes a floor panel 11 and wall panels 12, 13, 14, and 15.

Each wall panel 12 to 15 is constructed by attaching a board 17 to a wooden frame 16. An opening 12a for installing a window is formed in the wall panel 12 that is not adjacent to other house components. In addition, the wall panel 14 adjacent to other house components
An opening 14a is formed in the opening 14a for people to enter and exit.

Next, the floor panel 11 will be explained in detail. The floor panel 11 has a rectangular wooden frame 20. A plate material 22 is attached to the upper surface of the frame 20. A frame 20 is placed on the cloth foundation 2, and the wall panels 12 to 15 are connected to the frame 20. An intermediate beam 23 is spanned between the long sides 20a and 20b of the frame 20. Further, a first support beam 24 is spanned between the long side portions 20a and 20b in parallel with the intermediate beam 23. This first support beam 24 and one short side 20c of the frame 20
A plurality of second support beams 25 are spanned between. On the support beams 24 and 25, a floor plate 27 is installed.
is installed. Support beams 24 and 25 are frame 2
Since the vertical width is narrower than 0 and is connected to the lower part of the frame 20, the floor plate 27 is arranged at a lower position than the upper surface of the frame 20. An opening 28 is formed between the other short side 20d of the frame 20 and the intermediate beam 23. In addition, the intermediate beam 23 and the first support beam 2
4, an elongated opening 29 is also formed.

The bathroom core 30 includes a washing area 31, a bathtub 32,
Apron part (waist wall part) 33, wall parts 34, 35, 3
6, 37, and a ceiling portion 38, forming a box shape. Each part is made of press-molded FRP and is connected to each other in a liquid-tight manner.

The wall portion 34 includes a wall panel 12 of the house structure 10.
An opening 34a is formed at a location corresponding to the opening 12a, and a window 40 is installed in these openings 12a, 34a. The wall portion 36 has an opening 36a in a portion corresponding to the opening 14a of the wall panel 14.
This opening 36a is provided with a sliding door 41 for people to enter and exit. The bathroom core 30 also includes various equipment, such as a mirror 4.
2, a shelf 43, faucets 44, 45, a shower 46, a ventilation fan 47, etc. are provided.

In order to improve drainage, the washing area 31 is sloped so that it becomes lower toward the back from the sliding door 41 side, as shown in FIG. 2. A plurality of long legs 31a having different heights are formed on the bottom surface of the washing area 31 in accordance with this inclination. The washing area 31 is supported by placing the legs 31a on the floor plate 27 mentioned above. Note that the washing area 31 is formed with drainage grooves 31b and 31c. The groove 31b is arranged in the elongated opening 29 of the house structure 10, and a drain pipe (not shown) connected to the groove 31b is led downward through the opening 29.

The apron part 33 adjacent to the washing place part 31 is arranged higher than the washing place part 31. wall panel 1
An L-shaped fitting 48 is attached to the lower part of 2, and an adjustment screw 4 screwed into this L-shaped fitting 48
The apron part 33 is placed and supported on the upper end of the apron part 9 so that its height can be adjusted.

An opening 33a is formed in the apron section 33, and the bathtub section 32 is placed on the peripheral edge of the opening 33a. The bathtub section 32 projects downward from the washing area section 31. The bathtub portion 32 is inserted into the opening 28 of the floor panel 11 of the house structure 10. The bottom of the bathtub section 32 is placed on the support column 3 via the spacer 4. A drain pipe (not shown) is also connected to the bottom of the bathtub section 32.

The bath unit 1 having the above configuration is installed at a construction site as follows. First, a wire 61 is hooked to a hanging tool 60 attached to the upper end of the bath unit 1, and the bath unit 1 is hung by a crane, and the bath unit 1 is placed on the cloth foundation 2. Note that, at this point, the bathtub section 32 is not installed in the apron section 33. next,
After adjusting the height by placing the spacer 4 on the support column 3, the bathtub part 32 is installed on the apron part 33, and the bottom part is placed on the spacer 4. On the other hand, a roof (not shown) is attached on top of the house structure 10. In the above installation work, bathroom core 3
Since there is no need to place concrete on the ground A facing 0, work efficiency is improved. In addition, washing area 3
1 is formed with leg portions 31a having different heights corresponding to the inclination, and it is possible to omit the work of stacking spacers and the like to adjust the height, which also improves work efficiency.

In the bath unit 1 having the above configuration, the washing area 31 is supported by the floorboard 27, and the bathtub 32 is supported by the pillar 2.
Therefore, the bathroom core 30 is reliably supported.

Moreover, since the floorboard 27 is installed lower than the upper surface of the frame 20 of the floor panel 11, in other words, it is installed lower than the floor surface 65 of other house components adjacent to the bath unit 1, this floorboard The washing area 31 supported by the holder 27 can be installed low. Moreover,
As mentioned above, there is no need to interpose a spacer or the like for height adjustment between the washing area 31 and the floorboard 27,
Also from this point of view, the washing area 31 can be made lower. Therefore, the stepping height Ha when entering the washing area 31 from the floor surface 65 can be reduced, and the user can easily enter the bathroom.

Further, an opening 28 is formed in the floor panel 11, and the bathtub section 32 can be inserted into this opening 28, so that it is possible to adopt a configuration in which the bathtub section 32 protrudes below the washing area 31. As a result, the stepping height Hb when entering the bathtub section 32 from the washing area 31 can be lowered, making it possible to easily enter the bathtub section 32.
You can enter 2.

The present invention is not limited to the above embodiments and can be modified in various ways. For example, the washing area and the bathtub may be integrally formed.

Alternatively, it may be configured as shown in FIG. In FIG. 4, parts corresponding to those in the above embodiment are given the same numbers and detailed explanation thereof will be omitted. In this example, the bathtub section 32 is not placed on a support but is supported floating. That is, the hanging members 71 are attached to the two support beams 70 of the floor panel, and the hanging members 7
A support plate 72 is connected to the lower end of the support plate 72.
The bathtub section 32 is placed on top of the bathtub section 32 with a spacer 73 interposed therebetween. In this case, on-site construction is further simplified. Note that only the bathtub section 32 has a hanging structure, and the washing area section 31 is supported by the floorboard 27, so there is no problem with support strength.

(Effects of the invention) As explained above, the invention of the present application incorporates a bathroom core into a substantially box-shaped house structure to form a bathroom unit, making it easy to transport and install at a construction site. In addition, since the washing area of the bathroom core is supported by the floorboard provided at the bottom of the house structure, it is not necessary to pour concrete directly under the washing area, which improves work efficiency.
Can reliably support the bathroom core. In addition, since an opening is formed at the bottom of the approximately box-shaped house structure and the bathtub is inserted into this opening, the bathtub can be made to protrude below the washing area, and there is no need to cross between the washing area and the bathtub. The height can be reduced.
