Description

[Detailed description of the invention] [Field of industrial application] The present invention is a floor case that incorporates a toilet bowl with a rectangular outer periphery in plan view on a flat floor surface such as a concrete slab, as well as supply and drainage pipes and communication. This invention relates to a Japanese-style toilet unit in which a piping case incorporating a trachea and the like is installed.

[Conventional technology]

As a conventional construction method for installing toilet bowls, the wet construction method shown in FIG. 1 is generally used. In the conventional wet method, first, when pouring concrete, a box is placed on top of the formwork (not shown) to secure space for the toilet.
A fitting hole 3 for inserting a toilet bowl 2 is bored in a concrete slab 1. Then, a support block 4 is arranged around the fitting hole 3, and the toilet bowl 2 is fitted and arranged. After that, a waterproof layer 5 etc. is provided on the slab 1 and a water supply pipe 6 is connected, and then a predetermined A concrete layer 7, tiles 8, etc. are provided.

In addition to the above-mentioned wet method, there are also
Dry construction method shown in the figure (see Utility Model Publication No. 52-51902)
There is.

In this dry construction method, an opening 10 for installing a toilet bowl 2 is recessed in a slab 1, and a supply and
After the drain pipes 6 and 9 are arranged, a plate 11 is hung on the upper part of the opening 10, and the toilet bowl 2 is attached to the toilet bowl attachment hole 12 of the plate 11. If this is the case, there is no need to drill the insertion hole 3 in the slab 1, so a fire on the lower floor will not be transmitted to the upper floor, and it is possible to form a complete fireproof division. Furthermore, there is no need for detailed discussions between construction work and equipment work, making it possible to avoid trouble between the two contractors.

[The problem that the idea aims to solve]

However, in the above-mentioned conventional wet construction method, since the insertion holes 3 are bored in the concrete slab 1, the fireproof division from the downstairs is incomplete, and there is a risk that a fire may spread. In addition, since the toilet bowl 2 is attached to the insertion hole 3 previously provided in the slab 1,
It was not possible to change the layout when remodeling the toilet room. Furthermore, the construction work to form the insertion hole 3 in the slab 1 and the equipment work to install the toilet bowl 2 in the insertion hole 3 need to be carried out separately, and detailed discussions must be held between the contractors for both works. It was impossible. For this reason, if the connection is poor, the construction period may be prolonged and troubles may occur. In addition, the water supply pipe 6 is connected horizontally, whereas the drain pipe 9 is connected vertically so as to intersect the extension line of the water supply pipe. Moreover, this drain pipe 9 needs to be installed between the slab 1 and the ceiling (not shown) in the lower floor. Therefore, the space for drain pipe 9 (approximately 600 mm)
However, the disadvantage was that the floor height would be higher, which would increase the construction cost. Furthermore, most of the toilet bowl 2 is under the slab, and the piping is installed between the slab 1 and the ceiling below the floor as described above, so maintenance and
The drawback was that it required major construction work when replacing piping.

On the other hand, in the dry construction method shown in Fig. 2, the opening 10 is recessed between the floor and the ceiling, and the water supply pipe 6 and drain pipe 9 are arranged one above the other on the front end side of the toilet main body. Because of this necessity, the depth of the opening 10 is increased, which has the drawback of increasing the floor height accordingly, similar to the wet construction method. Furthermore, since the opening 10 is formed through construction work, it is also impossible to change the layout of the toilet bowl 2. Furthermore, in this dry construction method, it is possible to improve maintenance to some extent by providing an inspection hole 13 in the plate 11, but the supply/drainage pipes 6 and 9 are located below the toilet bowl 2 in the opening 10. Therefore, maintenance and replacement required major construction work.

In short, it has not been possible to install a satisfactory toilet using conventional wet and dry construction methods.

[Means to solve the problem]

Therefore, the present invention has been developed to improve and eliminate the above-mentioned drawbacks of the conventional method, and allows for extremely easy construction using the dry method without any processing on the slab, and also allows for lower floor heights. To provide a Japanese-style toilet unit that is easy to use and has a good appearance inside the toilet after construction.

Therefore, the means adopted by the present invention to solve the above problem is to construct at least two intermediate frames in parallel to the upper frame of the floor case made of frames made of lightweight section steel, etc. The space for inserting the toilet between the frames has a rectangular outer periphery when viewed from above, and the water supply port provided at the rear end of the toilet main body and the drain port provided at the front end of the toilet main body are in a straight line. A blow-out type Japanese-style toilet is inserted into the toilet, which is arranged approximately horizontally and has a jet hole for jetting cleansing water toward the drain outlet, and the shoulder of the Japanese-style toilet is locked to the intermediate frame;
A piping case framed by a frame made of lightweight shaped steel is placed adjacent to the floor case, and water supply pipes, drain pipes, ventilation pipes, etc. are built into the piping case, and the water supply port and drain port of the Japanese-style toilet are placed inside the floor case. The pipes are connected to the water supply pipe and drain pipe inside the piping case through connecting pipes, and a floor panel is attached to the entire upper surface of the floor case.

[Effect]

In a blowout type Japanese-style toilet, a water supply port provided at the rear end of the toilet bowl body and a drain port provided at the front end side of the toilet bowl body are arranged linearly and approximately horizontally. The water supply port and drain port of this Japanese-style toilet are arranged so that they are approximately horizontal within the floor case and are approximately parallel to each other with respect to the water supply pipe and drain pipe within the piping case. Connected by water supply connection pipe and drainage connection pipe. Therefore, unlike in the past, the extension lines of the water supply connection pipe and the drainage connection pipe do not intersect, and the water supply connection pipe and the drainage connection pipe are not arranged one above the other. Therefore, it is possible to reduce the dimensions required for the piping connections below the Japanese-style toilet bowl.

Additionally, a floor panel is attached to the entire top surface of the floor case. Therefore, maintenance and inspection of the connection status of the water supply connection pipe, drainage connection pipe, etc. and the back side of the toilet main body can be easily performed by simply removing the floor panel, which is extremely convenient.

〔Example〕

The configuration of the present invention will be explained below based on the embodiments shown in the drawings.

FIG. 3 is a perspective view showing the entire Japanese-style toilet unit (hereinafter referred to as toilet unit) 15 to which the present invention is applied, FIG. 4 is a longitudinal cross-sectional side view of the toilet unit 15, FIG. Figure 6 is a front view of the same. The toilet unit 15 has a piping case 16 and a floor case 17 (see FIG. 9). The piping case 16 is a vertically elongated frame 18 made of lightweight shaped steel or the like, and a water supply pipe 19, a drain pipe 20, a ventilation pipe 21, etc. are housed and held inside the pipe case 16. As shown in FIGS. 7 and 8, the piping case 16 is installed by inserting the anchor bolts 23 installed in the concrete slab 22 near the upright wall 28 into the cross frame 24 on the bottom side and tightening the nuts. 25, and at the same time tighten the adjustment bolts 27, 27 to the bottom side frames 26, 26.
The horizontal installation condition is adjusted by screwing them together. 7th
In the figures and FIG. 9, reference numeral 29 is a locking rail fixed to the upper front side of the piping case 16 by welding or the like, and is used to attach a front panel 30, which will be described later. This locking rail 29 has a locking groove 31 between it and the frame 18 of the piping case 16.

On the other hand, the floor case 17, as shown in FIG. 9, is a frame 18 made longer in the horizontal direction.
As in the case of the piping case 16, it is fixed onto the concrete slab 22 via anchor bolts 23, nuts 25, and adjuster bolts 27. A locking rail 32 similar to the locking rail 29 attached to the piping case 16 is also attached to the upper front side of the floor case 17 by welding or the like, and a frame made of lightweight shaped steel or the like forming the floor case 17 is attached. A locking groove 3 is provided between the
It has 3. The floor case 17 and the piping case 16 may be connected by bolts, welding, or the like, if necessary.

Next, the side panel 39 is placed on the front side of the floor case 17.
Attach. The side panel 39 has tiles 40 arranged and adhered to the surface of a gypsum board (not shown) or the like whose back side is reinforced with frames 44, 44 made of lightweight shaped steel, etc. A mounting rail 41 that fits into the locking groove 33 of the locking rail 32 is attached to the side with a tapping screw or the like. Reference numeral 42 denotes an adjustment bolt that passes through the mounting rail 41 and is screwed onto it. The tip of this bolt 42 is in contact with the upper surface of the locking rail 32, and the mounting rail 41 of the side panel 39
After fitting the bolt 4 into the locking groove 33,
2, it is possible to finely adjust the height of the side panel 39.

After the side panel 39 is attached to the front side of the floor case 17 in this way, the intermediate frame 43,
43 will be constructed. And, as shown in Figure 10,
When the toilet bowl 34 is installed, the floor panels 45, 46 are installed on the front and rear sides (from the diagonally lower left to the upper right in the figure).
and secure it with bolts etc. from the back side. Similarly to the side panel 39, the floor panels 45 and 46 are made of a frame made of lightweight section steel, a substrate such as gypsum board, and tiles.

After that, the toilet bowl 34 is attached to the intermediate frames 43, 43.
It is inserted into the space between them, and its shoulders 34a are locked to the side edges of the floor panels 45, 46. The toilet bowl 34 is supported by directly attaching its shoulder 34a to the intermediate frame 4.
3 and 43. Then, the water supply port 35 of the toilet bowl 34 and the water supply pipe 19 in the piping case 16 are connected by a water supply connection pipe 37, and the drain port 36 of the toilet bowl 34 and the drain pipe 20 of the piping case 16 are connected by a drainage connection pipe 38. Connect with. Toilet bowl 34
As shown in FIGS. 5 and 10, the outer periphery has a rectangular shape when viewed from above. Therefore, when tiles are used, the shape of the toilet bowl 34 harmonizes with each tile wall surface (including the floor surface 47), and it is possible to obtain an excellent design. Further, in the toilet bowl 34, as shown in FIG. 4, the water supply port 35 and the drain port 36 are arranged substantially horizontally and linearly, so that the water supply connection pipe 37 and the drainage connection pipe 38 are
It is not located below the toilet bowl 34,
There is no need to provide space for piping below the toilet bowl 34. Therefore, it is possible to set the height dimension of the floor case 17 small. For reference, in the conventional case shown in Figures 1 and 2, a space of 600 to 700 mm was required below the installation surface of the toilet bowl 2 (the top surface of the slab 1) as a space for piping. However, in the case of this embodiment, 300 mm or less is sufficient. Further, the toilet bowl 34 is of a blowout type in which a jet hole is formed in the middle of the flow path so that the flush water is spouted toward the discharge port 36.

Next, floor panels 48 and 49 which also serve as inspection plates are installed on the remaining upper surface of the floor case 17. The floor panels 48 and 49 have locking pieces 50 and 50 on the back side for engaging with the intermediate frame 43 and the frame 18 forming the floor case 17. The other configurations are substantially the same as those of the side panel 39 described above. To install the floor panels 48 and 49, slide them in from the front side of the floor case 17, and attach the locking pieces 50 and 50 to the intermediate frame 43.
Then, it may be engaged with and locked to the frame 18. This makes it easy to inspect the supply/drainage connections and the like at any time. Additionally, the toilet bowl 34 can be easily installed and replaced.

In this way, the floor panel 4 is placed on the floor case 17.
After installing the toilet bowls 4, 45, 48, and 49, a sealant or the like is filled between these floor panels and the shoulder portion 34a of the peripheral side of the toilet bowl 34 for waterproofing.

Then, as shown in FIGS. 3 and 6, a front panel 30 is attached to the front side of the piping case 16. This front panel 30 also has the same configuration as each of the panels described above. Installation is carried out by fitting the mounting rail 53 protruding from the upper part of the back side into the locking groove 31 of the piping case 16 and locking it there, and also by attaching the lower end surface of the panel to the end surface of the floor panels 45, 46, 48, 49. and the frame 18 of the piping case 16. Then, if necessary, install the mounting rail 53.
The height of the front panel 30 is finely adjusted by adjusting the adjusting bolt 55 screwed into the front panel 30. Note that the tip of the adjusting bolt 55 is in contact with the upper end surface of the locking rail 29.

Finally, the top plate 54 is attached to the top side of the piping case 16, and between the opening 19a of the water supply pipe 19 exposed to the front panel 30, which communicates with the water supply side, and the opening 19b, which communicates with the toilet side. What is necessary is to attach the flush valve 51 and connect both openings.

Thereby, it is possible to form a Japanese-style toilet unit 15.

Incidentally, in the above-mentioned embodiment, the case where one Japanese-style toilet unit 15 was assembled was explained, but it is also possible to install a plurality of them in series. Furthermore, panels similar to the side panel 39 can be attached to the left and right side surfaces (left and right side surfaces in FIG. 3) of the piping case 16 and floor case 17, if necessary.

[Effect of idea]

As explained above, according to the present invention, there is no need to drill a hole in the floor surface (concrete slab) for inserting a toilet bowl, so construction work is easy. It is possible to form the Moreover, it is easy to install the toilet bowl in any position and to change the installation position. In addition, in Japanese-style toilets, the water supply port provided at the rear end of the toilet body and the drain port provided at the front end of the toilet bowl body are arranged linearly and approximately horizontally. means that the water supply pipes and drainage pipes in the piping case are connected to each other by water supply connection pipes and drainage connection pipes that are arranged in a floor case in a substantially horizontal state and parallel to each other. ing. Therefore, unlike in the past, the extension lines of the water supply connection pipe and the drainage connection pipe do not intersect, and the water supply connection pipe and the drainage connection pipe are not arranged one above the other. Therefore, it is possible to reduce the required installation size below the Japanese-style toilet bowl. In other words, no space is required for piping below the toilet bowl, and the floor height can be reduced by that amount. Furthermore, as described above, the extension lines of the water supply connection pipe and the drainage connection pipe do not intersect, nor do they overlap vertically. In addition, the fact that the water supply connection pipe and drainage connection pipe are arranged in the floor case means that the water supply port is located above the floor of the toilet body. The water supply connection pipe is not exposed inside the toilet, which restricts the space inside the toilet, interferes with cleaning work, and does not make the appearance unsightly, as is the case with toilets.

On the other hand, the toilet bowl main body has a rectangular outer periphery when viewed from above, so it blends well with the tile wall surface (including the floor surface), etc., and it is possible to provide a toilet room with excellent design. Moreover, the floor panel etc. can be made into a rectangular shape in accordance with the shape of the toilet main body, and a part of the floor panel can also be used as an inspection board.
Therefore, by removably attaching a floor panel that also serves as an inspection plate, it is possible to extremely easily maintain the piping connections of the water inlet and drain outlet, the back surface of the toilet bowl, etc. Furthermore, the toilet itself can be replaced simply by removing the floor panel.
It's convenient.
