[Conventional technology]

There is a flush toilet where a Japanese-style toilet is attached to a through hole made in a floor between floors of a multi-story building such as a reinforced concrete building. In such a flush toilet, the floor concrete of the building is provided with a predetermined through hole, and the Japanese style toilet bowl is installed in the hole so that the lower surface of the Japanese style toilet bowl is on the ceiling below. Exposed.

[Problems to be solved by the invention]

As mentioned above, it can be said that no safety measures are taken in the flush toilet, and once a fire occurs, the toilet bowl is directly heated by heat or flame, so it can be easily destroyed.
In particular, when the container was rapidly cooled due to water discharge by the fire brigade etc., the destruction became more serious, the floor through hole opened widely, and a large flame was blown out, which may spread the fire to the upper floors. .

As a countermeasure against this, various flush toilets that cover the lower part of the toilet with a fireproof cover have been devised, but all of the fireproof covers that cover the lower part of this toilet have the necessary heat insulating properties and are of a structure that is easy to install. There was nothing. For example, fireproof covers made of concrete, G, R, C, etc. have excellent heat insulating properties, but are extremely heavy, so workability during installation is extremely poor. In addition, sheet metal products are light and have good workability, but have poor heat insulation properties, and the heat of the lower surface of the toilet conducts to the upper part, so it is difficult to keep the temperature of the upper exposed surface below the legal safety temperature of 260 ° C. Met.

The present invention has been made to solve the above-mentioned problems, and provides a flush toilet having a fireproof property in which a toilet bowl is covered with a fireproof cover which has a high cooling effect, is highly safe, is lightweight, and has good workability. Is intended.

[Means for solving the problem]

 The above object is achieved by the following means.

The flush toilet according to the invention of claim 1 is a toilet bowl that penetrates through a floor portion, and a fireproof portion that covers a buried portion of the toilet bowl and is provided with a water retention layer made of a swelling material having water absorbency. The water supply means for supplying water to the toilet bowl and the water guiding means for guiding the water supplied to the toilet bowl by the water supply means to the aquifer are provided.

In the flush toilet according to the invention described in claim 2, the fireproof part is configured such that the outer surface of the water retention layer is covered with a fireproof cover and a heat insulating material.

The flush toilet according to the invention of claim 3 is provided with a fixing means for attaching the fireproof cover to the heat insulating material.

Since it absorbs heat, the cooling effect is increased and the fire resistance is improved, new fire protection standards can be satisfied, and the fire resistant part is lightweight, so it is easy to handle and easy to install.

In the flush toilet according to the second aspect of the present invention, the fire resistance can be further improved by covering the fire resistant portion provided with the water retention layer with the outer surface of the water retention layer with the fire protection cover and the heat insulating material.

In the flush toilet according to the third aspect of the invention, since the fireproof cover is attached to the heat insulating material by the fixing means, the strength of the fireproof portion is increased, and the fireproof portion can be prevented from being damaged even in the event of a fire.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of a flush toilet showing an embodiment of the present invention. In the figure, 1 is a floor (floor portion) of a building, 2 is a fireproof cover (fireproof portion), and the upper end surface 3 of the fireproof cover 2 is attached so as to coincide with the floor surface 4 of the floor 1. Reference numeral 5 is a Japanese-style toilet bowl (toilet bowl) which is a floor-penetrating object installed through the floor 1. The Japanese-style toilet bowl 5 is mounted inside a fireproof cover 2, and the fireproof cover 2 allows the Japanese-style toilet bowl 5 to be installed. The buried part (the part buried under the floor 1) is covered. Reference numeral 6 denotes a heat insulating material (fire resistant portion) that covers the outer surface of the fire resistant cover 2. The heat insulating material 6 is a mounting bolt (fixing means).
It is fixed to the fireproof cover 2 by 7. The exposed head of the mounting bolt 7 is covered by a fireproof cap (fixing means) 16. 8 is a water supply spat portion (water supply means) provided at the front of the Japanese-style toilet 5, 5 is a cleaning tank (water supply means), 10 is a connection between the cleaning tank 9 and the water supply spat portion 8, and the water in the cleaning tank 9 is connected. Is a water supply pipe (water supply means) that guides the water to the water supply spat portion 8. When the cleaning valve (water supply means) 11 is opened, the water in the cleaning tank 9 passes through the water supply pipe 10 and the water supply spat portion 8 to supply water to the Japanese-style toilet bowl 5. From the mouth 12 to the Japanese-style toilet bowl 5
It is configured to flow in.

Reference numeral 13 is a water-bearing layer (fire-resistant portion) provided on the inner surface of the fireproof cover 2. The water-bearing layer 13 has a high water absorbing property and absorbs a very large amount of water relative to its own volume and swells. In addition, it is formed of a swelling material having the property of retaining its water content. The swelling material of the water retention layer 13 is in the form of particles or a flat plate, and is stored as a single body or in a film-like bag,
A water guiding pipe (water guiding means) 14 which is mounted so as to cover the inner surface of the fireproof cover 2 and which communicates with the water supply spat portion 8 is opened at an upper portion or a side surface thereof.

Since the swelling material of the water retention layer 13 does not absorb water at the time of mounting, it has a small volume and is lightweight, and the mounting work is easily performed. When the mounting work is completed and the flush toilet is ready for use, the flush valve 11 is opened by the user of the flush toilet and a part of the flush water flowing into the water supply spat portion 8 is introduced into the water conduit.
It is supplied from 14 to the swelling material of the aquifer 13. Since the swelling material supplied with water increases its volume while incorporating the water into its composition, a thick water-bearing layer 13 rich in water is formed on the inner surface of the fireproof cover 2. Since the water in the aquifer 13 is replenished each time the flush toilet is used, the water will not be reduced by evaporation or the like.

In such a state, a fire once occurs, the fire ignites around the ceiling of the toilet, the combustion state continues for a long time, and even if the heat insulating material 6 cannot provide heat insulation, the water in the aquifer 13 boils. As a result, an extremely large cooling effect is obtained, and the upper end portion 3 of the fireproof cover 2 is not heated.

FIG. 2 is a sectional view of a flush toilet showing another embodiment.
The same parts as those in FIG. 1 are designated by the same reference numerals, and the duplicate description will be omitted.

In this embodiment, a groove portion (fireproof portion) 15 is turned on the inner surface of the fireproof cover 2, and the above-mentioned swelling material is housed in this groove portion 15 to form an aquifer 13, and a water conduit 14 is also used for flush toilets. Water is supplied each time it is used. Therefore, it has the same operation and effect as the above-mentioned embodiment.

Although the embodiments of the present invention have been described above, various effective modifications can be made based on the present invention, and the arrangement and shape of the aquifer are not limited to the above embodiments.
