Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a Japanese-style toilet unit used when constructing a Japanese-style toilet on a flat concrete slab using a so-called dry construction method.

[Conventional technology]

Conventionally, there are two methods for installing Japanese-style toilets: a wet method and a dry method. In the wet method, as shown in Figure 1, first, when pouring concrete, a box is placed on top of the formwork (not shown) to secure space for the toilet, and then a Japanese-style toilet 2 is inserted into the concrete slab 1. insertion hole 3
is installed. Then, a support block 4 is arranged around the fitting hole 3, a Japanese-style toilet bowl 2 is fitted and arranged, and then a waterproof layer 5 is placed on the concrete slab 1.
etc. are provided to connect the water supply pipe 6, and then a predetermined concrete layer 7, tiles 8, etc. are provided. In addition, in the case of the dry construction method, as shown in Fig. 2a and b, an opening 10 for installing a Japanese-style toilet 2 is recessed in the concrete slab 1, and the supply/drainage pipes 6, 9 are inserted into the opening 10. After arranging the plate 11, the plate 11 is hung on the upper part of the opening 10, and the Japanese style toilet 2 is attached to the toilet attachment hole 12 of the plate 11.

[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. Furthermore, since the Japanese-style toilet bowl 2 is attached to a fitting hole 3 previously provided in the concrete slab 1, the layout cannot be changed when the toilet room is remodeled or the like. Furthermore, the construction work to form the insertion hole 3 in the concrete slab 1 and the equipment work to install the Japanese-style 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. I had to. For this reason, poor communication could prolong the construction period and cause problems.
In addition, the drain pipe 9 needs to be installed between the concrete slab 1 and the ceiling (not shown) on the floor below, which increases the floor height by the space required (approximately 600 to 700 mm), which increases construction costs. There were flaws. Furthermore, most of the Japanese-style toilet 2 is located under the slab, and as mentioned above, the piping is installed between the concrete slab 1 and the ceiling of the floor below, so maintenance, replacement of the piping, etc. requires major construction work. It was hot. In the conventional dry construction method, there is no need to drill holes 3 in the concrete slab 1.
A fire on the floor below does not spread to the upper floor, making it possible to create a complete fireproof zone, and eliminating the need for detailed discussions between building work and equipment work.
It is possible to avoid trouble between the two companies. However, since the opening 10 needs to be recessed between the floor and the ceiling, there is a drawback that the floor height becomes high, similar to the wet construction method. Further, since the opening 10 is formed through construction work, it is also impossible to change the layout of the Japanese-style toilet bowl 2. Furthermore, in this dry construction method, an inspection hole 1 is provided in the plate 11.
Although it is possible to improve maintenance to some extent by providing openings 1 and 3, the supply/drainage pipes 6 and 9 are
Since it is located below toilet bowl 2, maintenance and replacement would be a major undertaking. In short, conventional wet and dry construction methods have not been able to install satisfactory Japanese-style toilets. In order to solve the above-mentioned problems, the present invention allows a Japanese-style toilet to be installed on a flat concrete slab using a dry construction method. The purpose of the present invention is to provide a Japanese-style toilet unit that has a very low space (hereinafter referred to as "underfloor space") and allows equipment work such as piping to be easily performed in the underfloor space.

[Means to solve the problem]

The gist of the present invention for solving the above problems is to provide a piping case that is installed on a flat concrete slab and that incorporates a water supply pipe, a drainage pipe, a ventilation pipe, etc. on the concrete slab. It is installed adjacent to the piping case, and includes a floor case with a toilet insertion hole in the upper floor surface, and a Japanese-style toilet with the lower half inserted into the floor case through the toilet insertion hole, Japanese-style toilets are arranged so that the front side of the toilet in the longitudinal direction facing the toilet user faces the piping case, and a water inlet is provided on the upper surface of this front side, and the lower half of the toilet is located on the same side as the water inlet. A drain port is provided approximately horizontally in the extending direction from the front end in the longitudinal direction of the toilet, and the water supply port of the Japanese-style toilet and the water supply pipe are connected by a water supply connection pipe either directly or through the floor case. The drain port and the drain pipe are connected by a drain connecting pipe through the inside of the floor case, and the floor case is provided with an inspection port with a lid on the floor area located above the drain connecting pipe. .

[Effect]

When installed on the concrete slab, the piping case and floor case form the interior surface and floor surface of the toilet compartment. In Japanese-style toilets, the height of the lower half is low because the toilet drain is provided approximately horizontally in the extending direction from the front end in the longitudinal direction of the toilet in the lower half inserted into the floor case. Furthermore, Japanese-style toilets are arranged so that the front side of the toilet in the longitudinal direction facing the toilet user faces the piping case, and a water inlet is provided on the upper surface of this front side, and a water inlet is provided at the bottom on the same side as the water inlet. Since the drain port is provided approximately horizontally in the extending direction from the front end of the toilet in the longitudinal direction in the half part, the distance between the water supply port and drain port and the corresponding water supply pipe and drain pipe incorporated in the piping case is Becomes shorter. An inspection port with a lid is provided on the floor above the drain connection pipe, so when connecting the drain port of a Japanese-style toilet and the drain pipe with the drain connection pipe, connect through the inspection port. can be done. Since the drain port of the Japanese-style toilet bowl and the drain pipe are connected by the drain connection pipe through the interior of the floor case, the drain connection pipe etc. are not exposed in the toilet room where the toilet user can see them.

[Effect of the idea]

As detailed above, the present unit has the following practical effects. All construction work can be done on concrete slabs, and the dry construction method makes construction easy. Since all construction work can be done on a flat concrete slab, changes in the layout of the Japanese-style toilet can be easily accommodated. Since all construction work can be carried out on a flat concrete slab, it is possible to solve the problem of fire protection compartments where Japanese-style toilets are installed, which tends to be incomplete in the past, and even if a fire breaks out downstairs, it will not spread to the upper floors. There is no A Japanese-style toilet can be installed without penetrating the concrete slab, so there is no chance of water leaking downstairs. The required storage height of the Japanese-style toilet, including the connection with the drain pipe in the floor case, can be reduced to approximately 300 mm, and all construction work can be done on a flat concrete slab, reducing the under-floor space required to install the Japanese-style toilet. The size can be significantly reduced to about half of the conventionally required size (600 to 700 mm). As a result, the proposed unit can save the floor height of the building by that much, making it possible to dramatically reduce construction costs. In a Japanese-style toilet, the front side in the longitudinal direction of the toilet faces the piping case, and the water supply port and drain port are provided on the front side. The distance to the drain pipe becomes shorter and the number of bend piping points can be reduced. As a result, the proposed unit simplifies piping work and maintenance inspection. Since an inspection port with a lid is provided on the floor above the drain connection pipe, piping work for the Japanese-style toilet can be performed through the inspection port. As a result, the proposed unit simplifies piping work and maintenance inspection.
