Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a construction method for converting an existing flush-type Japanese-style toilet into a seated toilet, and specifically relates to a method in which a Japanese-style toilet is embedded in a concrete floor.

Conventionally, when converting this type of Japanese-style toilet into a seated toilet, the following procedure was followed.

○A Separate the connection between the drain of the Japanese-style toilet and the defecation pipe under the floor or downstairs.

○B Remove the water supply pipe to the Japanese-style toilet.

○C Remove the Japanese-style toilet bowl by crushing it.

○D Connect a defecation connecting pipe to the tip of the defecation pipe removed under the floor or downstairs, and raise the upper end of the connecting pipe higher than the installation floor.

○E After removing the Japanese-style toilet, a formwork will be built on the underside of the concrete floor and mortar will be poured in to fill the opening and make the floor flat.

○F After the mortar has hardened, remove the formwork and
Attach a floor flange fitting to the defecation connecting pipe.

G. Install a seated toilet on the floor, fix its drain port to the floor flange metal fittings via a sealant, and connect a water supply pipe to the water supply port.

Therefore, the remodeling work required a great deal of time and labor, resulting in high construction costs and the problem that the toilet could not be used for several days until the work was completed.

The present invention aims to solve these problems, shorten the construction time, reduce construction costs, and make the toilet usable on the same day.

The basic structure of the present invention is to break the saucer, etc. located above the drain of an existing flush-type Japanese-style toilet to expose the drain, and use the drain as-is to defecate without completely removing the Japanese-style toilet. After a connecting pipe is erected and a mounting member that immovably supports the defecation connecting pipe is fixed to the Japanese-style toilet or the floor, a seated toilet is installed to cover the Japanese-style toilet.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The existing flush-type Japanese-style toilet A is well known in this kind of technical field, and the one shown has a water supply port A4 at the front of the upper part and a trap part A5 at the front of the lower part.
It is a so-called flushing type with a drain port A1 formed at the rear of the lower part, and a water supply pipe 1 connected to a water supply device (not shown) such as a flush valve or a tank is connected to the water supply port A4. A defecation pipe 2 made of a lead pipe or a vinyl chloride pipe is connected to the drain port a1.

First, remove the water supply pipe 1 from the water supply port a4 of this Japanese-style toilet A, and tap the saucer part a2 located above the drain port a1 with a hammer or the like to create a passage that is larger than the size through which the defecation connecting pipe C, which will be described later, can be inserted. Drill hole 3,
The drain port a1 is exposed.

At this time, if adhesive tape or the like is applied to the saucer part a2 in advance before breaking it, it is possible to prevent clogging and the like caused by fragments directly entering the defecation pipe 2.

Next, a cylindrical defecation connecting pipe C made of synthetic resin or the like is inserted and connected to the drain port a1.
Normally, the drain port a1 is narrowest at the bottom and widens toward the top, so a collar piece c1 that locks on the inner surface of the drain port a1 is integrally protruded on the outer circumferential surface of the defecation communication pipe C. The lower surface of the collar piece c1 is connected to the drain port a1 via the adhesive sealing material 4 for preventing water leakage.
By crimping the inner surface, the defecation communication pipe C is temporarily fixed in a substantially vertical shape.

Further, on the rear upper surface of the Japanese-style toilet A, a mounting member D is installed extending from the upper part of the defecation communication pipe C to the upper surface of the rim a3 of the Japanese-style toilet A or the floor surface E.

The mounting member D is formed into a plate shape of metal, hard synthetic resin, etc., and has an insertion hole d1 in the center thereof through which the upper part of the defecation communication pipe C is inserted.
The rim is bent diagonally downward toward the center to form a flange portion d2, and a plurality of projecting pieces d3 are hung from the periphery to face the inner surface of the rim a3 of the Japanese-style toilet A, or the left and right inner wall surfaces in the drawing. do. Fixing bolts d4 are respectively screwed onto these projecting pieces d3 so that they can move forward and backward from the inside of the mounting member D toward the inner surface of the rim a3 of the Japanese-style toilet A, and when the bolts d4 are tightened, the tips thereof are By pressing against the inner surface of the rim a3, the mounting member D is immovably fixed.

Incidentally, the mounting member D is not limited to a plate shape, but may be formed in any shape as long as an insertion hole d1 through which the defecation communication tube C is inserted can be formed in the center part b, and a piece d3 having a fixing bolt d4 protruding in the peripheral part can be formed. The shape may be arbitrary, for example, made of a wire.

After fixing the above mounting member D, as before,
The upper part of the defecation communication pipe C, which could protrude upward from the insertion hole d1 of the mounting member D, was cut at appropriate points, and the tip was expanded along the flange part d2 formed at the periphery of the insertion hole d1. After that, a seated toilet B is installed so as to cover the Japanese-style toilet A, and the lower end of this seated toilet B is immovably fixed to the floor surface E with fixing screws 5, etc., and the drain port of the seated toilet B is fixed. b1
is fixed to the expanded portion c2, which is the upper end of the defecation communication pipe C, via a sealing material 6.

At this time, the defecation communication pipe C is inserted into the insertion hole d of the mounting member D.
1 prevents movement in the horizontal direction and also prevents vertical movement due to the weight of the seated toilet B. This prevents water leakage due to the movement of the defecation connecting pipe C due to the drainage force generated when washing the seated toilet B. It never happens.

Finally, the water supply pipe 1 is connected to the seated toilet bowl B, and the remodeling work is completed.

Next, what is shown in FIG. 5 is a second embodiment,
In this case, a floor flange fitting d5 having an insertion hole d1 and a flange portion d2 is formed separately from the mounting member D, and the floor flange fitting d5 is integrated into the center of the mounting member D with a mounting screw d6 or adhesive. At the same time, a tightening bolt d7 is screwed onto this mounting member D so that it can move forward and backward toward a horizontal side c3 that projects from above on the upper outer peripheral surface of the defecation communication pipe C.

Therefore, in this second embodiment, the defecation connecting pipe C can be more firmly fixed by screwing in the tightening bolt d7 and pressing its tip against the horizontal side c3 of the defecation connecting pipe C. .

Furthermore, what is shown in FIG. 6 is a third embodiment, in which the inner diameter of the upper end of the defecation communication pipe C is formed to be larger than the outer diameter of the drain port b1 of the seated toilet B, and the large diameter part c4 An annular rubber gasket 7 having a substantially L-shaped cross section is interposed between the drain port b1 and the drain port b1.

Therefore, in this third embodiment, there is no need to form a flange portion d2 at the center of the mounting member D, and there is no need to form a flange portion d2 between the defecation communication pipe C and the drain port portion d1 of the seated toilet B. There is no need to interpose the sealing material 6, and the work is easy.

In the above embodiment, the front cover part a6 of the Japanese-style toilet bowl A was not removed, and the seat toilet B was installed with the front cover part a6 attached, so that the front cover part a6 was removed as shown in FIG. Although it is exposed outward from seated toilet bowl B,
However, the present invention is not limited to this, and the entire Japanese-style toilet bowl A may be backfilled by removing the front covering part a6 and pouring mortar or the like into the space inside the Japanese-style toilet bowl A. Even in this case, the seated toilet B can be installed without waiting for the mortar to harden.

In addition, without removing the front cover part a6 of the Japanese-style toilet bowl A,
A cover or the like may be separately attached to cover the front cover part a6.

Since the present invention has the above configuration, it has the following advantages.

Break the saucer located above the drain of the existing flush Japanese-style toilet to expose the drain, connect the defecation connecting pipe to this drain, and connect the defecation connecting pipe to the top of the rim of the Japanese-style toilet or the After fixing a mounting member that immovably supports the defecation connecting pipe across the floor, a seated toilet is installed to cover the Japanese-style toilet, and the drain port of the seated toilet is connected to the defecation communicating pipe. Therefore, the existing Japanese-style toilet or the connecting part of the Japanese-style toilet to the drain outlet and defecation pipe can be used as is without removing it, and a seated toilet can be installed without backfilling the floor as in the past.

Therefore, construction time can be shortened, construction costs can be reduced, and the toilet can be used on the same day.

All remodeling work can be done only on the floor where the Japanese-style toilet is installed, so it is an extremely useful construction method in places where it is difficult to work under the floor or downstairs.
