Description

The present invention is a Japanese-Western exchange division plate method for changing a toilet room in which a Japanese-style toilet is installed into a toilet room in which a Western-style toilet is installed. Specifically, Japanese-Western urinal replacement split plate method used for Japanese-style toilets mounted on floor slabs consisting of concrete floors or deck plate floors.

A Japanese-style toilet in a toilet room such as a building is provided with an opening hole for installing a Japanese-style toilet in a concrete floor slab or a deck floor slab, and the Japanese-style toilet is installed so as to be fitted into the opening hole from above. A drainage pipe is connected to the drainage outlet of the Japanese-style toilet, and the ceiling below the floor is routed and connected to the drainage vertical pipe of the building.

When replacing a Japanese-style toilet in a toilet room with a Western-style toilet, all the Japanese-style toilet is removed, the drainage pipe is raised to the existing floor finish surface, and reinforcing bars are placed in the opening holes of the Japanese-style toilet to fill with concrete. There is a method in which a floor slab is newly formed and the Western-style toilet is installed thereon. However, it takes time to dispose and dismantle the Japanese-style toilet and to dispose of dust in the ceiling below the floor, and work from the bottom is required, which increases the work period and costs.

In Japanese Patent No. 3183295, as a method capable of exchanging Japanese and Western toilets only on the floor, the upper part of the Japanese-style toilet installed on the floor of the toilet room is removed, and a drain pipe is connected to the drain outlet of the Japanese-style toilet. A method is described in which the Japanese-style toilet is started up, the interior of the Japanese-style toilet is laid out with reinforcing bars and filled with a self-hardening filler, and the Western-style toilet is installed thereon.

5 to 9 of the same publication, the floor slab of the toilet room and the upper edge of the Japanese-style toilet are removed, a drain pipe is connected to the drainage port of the Japanese-style toilet, A method is described in which a plate is placed on the floor base, filled with a self-hardening filler, and a Western-style toilet is placed thereon.

As a method capable of exchanging Japanese and Western toilets only on the floor, Japanese Patent Publication No. 2007-205028 removes the upper part of the Japanese-style toilet installed on the floor of the toilet room and communicates with the drainage outlet of the Japanese-style toilet. Is described, and a foaming sheet is fitted into the upper part of the Japanese-style toilet as a cover, and a scattering prevention sheet or a bead made of Happo resin is attached to prevent the Japanese-style toilet from dropping and scattering.
Japanese Patent No. 3183295

The method of filling the Japanese-style toilet of Japanese Patent No. 3183295 with a self-hardening filler is such that cracking occurs in the Japanese-style toilet due to shrinkage or expansion as the filler is cured, and the weight increases due to the filling inside the toilet bowl or the Western-style toilet There is a risk of falling off without being fully supported by the load applied to the. Also, if the opening area of the floor slab in the toilet room is set larger than the specified size, the load bearing capacity will decrease because the floor slab support area of the Japanese-style toilet is small, and the load may not be sufficiently supported and may fall off. This method seems to be unsuitable.

Also, in the same publication, FIGS. 5 to 9 describe a construction method in which the floor slab is deeply removed and a plate is placed inside the toilet bowl. In this construction method, since the floor slab is removed deeply, the load bearing capacity of the floor slab that supports the Japanese-style toilet is reduced, and there is a risk of the floor slab falling off or cracking or the cracking of the Japanese-style toilet. In addition, a method of supporting a load on the floor with one plate or two or more plates is described. In this construction method, it is necessary to process the start-up position of the connecting drainage pipe of the toilet bowl and the anchor position of the toilet bowl according to different dimensions at each site. Also, the plate is not easy to carry and takes time and effort. And since the drain pipe in the toilet bowl of this Japanese-style toilet bowl uses the drain pipe of the flat-shaped special shape, the cost is high.

The Japanese-style toilet of the above-mentioned Japanese Patent Publication No. 2007-205028 describes a method for removing the floor slab to a deeper level than the upper surface. This method is the same as above, and since the floor slab is removed deeply, the load bearing capacity of the floor slab that supports the Japanese-style toilet is reduced, and there is a risk of the floor slab falling off or cracking or the cracking of the Japanese-style toilet.

The present invention provides a Japanese / Western urinal replacement split plate method in which an upper portion of a Japanese-style toilet is removed and a Western-style toilet is installed thereon. Provided is a method for exchanging Japanese and Western toilets which maintains the strength of existing floor slabs before the exchange of Japanese-Western toilets, prevents breakage and dropout of Japanese-style toilets, and is simple in work, short in construction period and low in material cost.
