As described above, in the invention of claim 1 , the sanitary equipment can be constructed only from the installation floor without removing all the Japanese-style toilets and existing water supply / drainage pipes. The work period can be shortened because the removal work of Japanese-style toilets, the work of collecting pieces of Japanese-style toilets from the bottom of the ceiling below the floor, the work of disassembling and arranging pipes can be omitted, and the waste disposal work can be reduced. it can. In this invention, since the convex part from the existing floor surface is reduced, the kind of sanitary equipment attached increases. Also, the floor finishing part and the floor base part around the Japanese style toilet bowl were removed, and both ends of the rebar longer than the width of the Japanese style toilet bowl were hooked on the floor base part, so an excessive load from above or vibration due to earthquakes, etc. It is possible to prevent the non-removal part of the Japanese-style toilet from falling down.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the upper part of the toilet bowl 3 of the Japanese-style toilet is cut, while the connecting pipe insertion port 5 is provided in the toilet bowl 3 of the Japanese-style toilet, and the connection pipe 1 is inserted from above the connecting pipe insertion port 5. Since the sanitary equipment 4 is attached, the sanitary equipment 4 such as a sitting toilet and a wash counter can be constructed without removing all of the Japanese-style toilet 2 and the existing water supply and drainage pipes 7. In addition, although the toilet bowl part 3 upper part of the Japanese style toilet bowl and the removal method of the toilet bowl part 3 can be easily cut using common cutting tools, such as a disk grinder, it is not specifically limited. Moreover, about the removal structure above the toilet bowl part 3 of a Japanese-style toilet bowl, if all the rim water channel parts 8 which support the Japanese-style toilet bowl 2 are removed, the Japanese-style toilet bowl 2 may fall downstairs. So long as it does not fall downstairs, it may be partially removed, and its removal structure is not particularly limited. Moreover, you may remove not only the Japanese style toilet bowl 2 but the floor finishing part 9 and the floor base part 10 around the Japanese style toilet bowl 2. In the illustrated example, the Japanese-style toilet 2 is removed so as to be flush with the existing floor finishing portion 9 and the sanitary equipment 4 is constructed, but the construction structure is not particularly limited. Moreover, about the removal structure of the toilet bowl part 3 of a Japanese-style toilet bowl, as long as it is the magnitude | size beyond the outer diameter of the connection piping 1, it is not specifically limited, You may remove all.

As shown in FIG. 2- (a), while removing the upper part of the toilet bowl 3 of the Japanese-style toilet, a connection pipe insertion port 5 is provided in the toilet bowl part 3 of the Japanese-style toilet, and the connection pipe is installed from above the connection pipe insertion port 5. After inserting 1, the sanitary equipment 4 can be constructed without removing all of the Japanese-style toilet 2, the existing water supply pipe 6 and the drain pipe 7 because the filler 12 is filled from above the Japanese-style toilet 2. The filler 12 to be used may be used in combination of two or more, as long as it can be filled from above the non-removal part 11 of the Japanese-style toilet, and is not particularly limited. In addition, if fast-curing self-leveling material is used, the surface can be finished without unevenness with a simple trowel, and when the floor finishing material is constructed, the uneven surface repair work can be omitted and the construction period can be further shortened. is there. In addition, the construction structure is preferably filled so that the filler 12 does not enter the existing drain pipe 7 as in the illustrated example, and the new floor finish 13 is flush with the existing floor finish 9. If constructed in this way, the step with the existing floor finishing portion 9 is eliminated, and the user is safe without being hesitated. Further, if a fast-curing self-leveling material or a fast-curing mortar is used for the filler 12, the curing time until drying can be shortened, and therefore the work period can be further shortened.

On the other hand, with respect to the water supply system, in the illustrated example, after the floor finishing portion 9 and the existing floor base portion 10 around the Japanese-style toilet bowl 2 are removed, the existing water supply pipe 6 is cut and the existing water supply pipe is directly cut without cutting the screw. 6 is connected to the newly established water supply pipe 15 using the pipe joint 14 that can be connected to the pipe 6, so that it can be finished in the same manner as the prior art without any work from the downstairs, but the connection structure is particularly limited. Not. In addition, when the height from the upper surface of the existing floor finishing portion 9 to the lower surface of the floor base portion 10 is low and the existing water supply pipe 6 and the new water supply pipe 15 cannot be connected within the height, FIG. As described above, the concrete slab 16 may be partially removed.

As shown in FIG. 3- (a), when filling with the filler 12 from above the non-removal part 11 of the Japanese-style toilet, a new reinforcing bar 17 is embedded together with the filler 12, and filling is performed due to an excessive load from above. It is possible to prevent the non-removal portion 11 of the Japanese-style toilet embedded in the material 12 from falling down. In the illustrated example, the Japanese style toilet 2 and the floor finishing portion 9 and the floor base portion 10 around the Japanese style toilet bowl 2 are removed, and then a new reinforcing bar 17 longer than the width of the Japanese style toilet bowl 2 is hung on the floor base portion 10. In the state, the non-removal part 11 of the Japanese-style toilet is embedded with the filler 12, but the structure is not particularly limited. The shape of the new reinforcing bar 17 is not particularly limited as long as it is configured to fit in the non-removal part 11 of the Japanese-style toilet, not to be buffered with the connection pipe 1, and to be hooked on the existing floor base part 10 at both ends, An example is shown in FIGS. 3- (b), (c), and (d). In addition, the number of newly installed reinforcing bars 17 is not limited to one, and two or more reinforcing bars 17 may be used as long as they fit within the non-removal portion 11 of the Japanese-style toilet.

As shown in FIG. 4, a cushioning material 18 is placed between the non-removal portion 11 and the filler 12 of the Japanese-style toilet that is buried. The buffer material 18 to be used may be used in combination of two or more, as long as it can absorb expansion and contraction during curing of the filler material 12, and is not particularly limited. In the illustrated example, the cushioning material 18 is processed on the entire surface of the non-removable portion 11 of the Japanese-style toilet. However, if the expansion and contraction during the curing of the filler 12 can be absorbed, partial processing may be performed. There is no particular limitation.

As shown in FIG. 5, while removing the floor finishing part 9 and the floor base part 10 around the toilet bowl 3 of the Japanese-style toilet bowl and around the Japanese-style toilet bowl 2, the connecting pipe insertion port 5 is provided in the toilet bowl section 3 of the Japanese-style toilet bowl. The connecting pipe 1 is inserted from above the connecting pipe insertion port 5, and the connecting pipe 1 is inserted into the connecting pipe insertion port 20 of the floor plate 19 provided with the connecting pipe insertion port 20 from above the Japanese-style toilet 2. The sanitary equipment 4 is attached to the connecting pipe 1. The shape of the floor plate 19 is suitable so that the floor plate 19 can be placed without any gaps, so that it substantially coincides with the removal portion, but as long as the shape can sufficiently support the sanitary equipment 4, It is not limited. The material is preferably a rigid body such as an iron plate that can sufficiently support the sanitary equipment 4, but is not particularly limited as long as it can sufficiently support the sanitary equipment 4, and may have a finish. In the illustrated example, the floor plate 19 can be placed so as to be flush with the existing floor finishing portion 9 and the sanitary equipment 4 can be constructed flush with the existing floor finishing portion 9, so that the appearance can be finished well. The level difference from the existing floor finish portion 9 is eliminated, and the user is safe and safe, but the construction structure is not particularly limited.

Further, as shown in FIG. 6A, when one floor plate 19 is used, the floor plate 19 always includes a connection pipe insertion port 20, and the shape of the connection pipe insertion port 20 is a connection pipe. If it is more than 1 outer diameter, it will not specifically limit. Further, as shown in FIG. 6B, the number of floor plates 19 is not limited to one, and two or more floor plates 19 may be used in combination. When two or more floor plates 19 are used in this way, the floor plate 19 Since the connection pipe insertion port 20 is provided by the combination, the floor plate 19 does not necessarily have to include the connection pipe insertion port 20.

Further, as shown in FIG. 7, the floor plate 19 may also have a support portion 21, and may be integral with or separate from the floor plate 19. Since the floor plate support 21 to be used needs to support the floor plate 19, a material having high rigidity such as carbon steel is desirable, but is not particularly limited as long as the floor plate 19 can be supported. Note that the number of the support portions 21 is not limited to one, and if two or more support portions 21 are used, more sufficient support is possible.

As shown in FIG. 8, the floor plate 19 is configured so that the height can be adjusted. Therefore, even if the floor surface to be installed is uneven, the height adjustment and the horizontal adjustment of the floor plate 19 are easily performed. The construction period can be shortened. About the height adjustment function of the floor plate 19, even if the floor plate 19 in which the height adjustment function is integrated may be used, another member capable of height adjustment may be used. A height adjusting member can be attached according to the site, and the height can be adjusted at a portion where the unevenness of the floor surface on which the floor plate 19 is placed is small. Further, the height adjustment function is not limited to one, and if two or more are used, more accurate height adjustment and horizontal adjustment are possible. In the illustrated example, the floor plate 19 is provided with a through hole, and a floor plate leg member 22 that is female threaded is attached so as to cover the through hole, and the height adjusting leg 23 that is male threaded is vertical. It is structured to be screwed in the direction. Although the height adjustment and the horizontal adjustment can be performed by the screwing condition of the height adjustment leg 23, the adjustment structure is not particularly limited as long as the height adjustment and the horizontal adjustment can be performed. In addition, since the height adjusting leg 23 in this example needs to support the floor plate 19, for example, a material having high rigidity such as carbon steel is desirable, but is not particularly limited as long as the floor plate 19 can be supported.

As shown in FIG. 9, since the floor plate finishing material 24 is provided on the upper part of the floor plate 19 and the sanitary equipment 4 is attached to the connection pipe 1, it can be finished with good appearance. The floor plate finishing material 24 is not particularly limited in size, material, and shape as long as the floor plate finishing material 24 can be applied to the top of the floor plate 19. In the illustrated example, the Japanese style toilet bowl 2 and the floor finishing section 9 and the floor base section 10 around the Japanese style toilet bowl 2 are removed, the floor plate 19 is placed, and the existing floor finishing section 9 and the floor plate finishing material are placed. Since the floor plate finishing material 24 is arranged so as to be flush with the floor 24 and the sanitary equipment 4 is installed on the connecting pipe 1, it can be finished with a good appearance and has a step difference from the existing floor finishing section 9. Is eliminated, and the user does not hesitate and is safe.

As shown in FIG. 10, since the filler 12 has been waterproofed, it is possible to prevent water leaking downstairs from the gap between the Japanese-style toilet 2 and the existing floor finishing section 9 and floor floor section 10. The waterproofing method includes a method of attaching a waterproof sheet or applying a waterproof coating, but is not particularly limited as long as it can be waterproofed. Preferably, as shown in the illustrated example, the upper part of the toilet bowl 3 of the Japanese-style toilet is removed, while the connection pipe insertion port 5 is provided in the toilet bowl part 3 of the Japanese-style toilet, and the connection pipe 1 is connected from above the connection pipe insertion port 5. If a new waterproof layer 26 is connected to the existing waterproof layer 25 after being inserted and filled with the filler 12 from above the Japanese-style toilet 2, and cured, a complete waterproof structure can be secured. Furthermore, if the filler 12 having a high waterproof performance such as a waterproof mortar is used as the filler 12, the waterproof performance of the construction structure can be improved, water leakage to the downstairs can be prevented, and the shrinkage rate during curing is low. If the filler 12 such as mortar is used, it is possible to prevent water leaking downstairs from the gap between the Japanese-style toilet 2 and the existing floor finishing portion 9 and the floor foundation portion 10.

As shown in FIG. 11, the connection pipe 1 can be firmly supported by the drainage port 27 of the Japanese-style toilet by connecting the connection pipe 1 and the drainage-portion 27 of the Japanese-style toilet, so that the non-removal part 11 of the Japanese-style toilet is embedded. When this is done, the connecting pipe 1 is not displaced, and the non-removal portion 11 of the Japanese-style toilet can be easily embedded. Furthermore, malodor generated from the existing drain pipe 7 can be prevented. In the illustrated example, the connection pipe 1 and the drainage port 27 of the Japanese-style toilet are connected and fixed by the adhesive 28 by interpolating the connection pipe 1 around the drainage port 27 of the Japanese-style toilet using the adhesive 28. However, the connection structure is not particularly limited, and packing may be used.

As shown in FIG. 12- (a), since the connection pipe 1 having an outer diameter smaller than the minimum diameter of the drainage port 27 of the Japanese-style toilet is used at least partially and connected to the existing drainage pipe 7, Even if a crack is generated in the drainage port 27 of the Japanese-style toilet, water leakage to the downstairs from the crack can be prevented. In the illustrated example, the connection pipe 1 and the existing drain pipe 7 are connected by using the adhesive 28 and the connection pipe 1 is inserted around the existing drain pipe 7 and fixed by the adhesive 28. The connection structure is not particularly limited, and packing may be used.

Moreover, even if the pipe diameter of the connection pipe 1 is large, the connection pipe 1 and the existing drain pipe 7 can be connected by removing the drain outlet 27 of the Japanese-style toilet as shown in FIG. In the illustrated example, the removal structure of the drain outlet 27 of the Japanese-style toilet bowl is substantially the same as the outline of the connecting pipe 1, so even if the filler 12 is filled, it does not fall downstairs, As long as the filler 12 does not fall, the removal structure is not particularly limited, and may be removed entirely.

As shown in FIG. 13, if the elastic member 29 is provided in the connecting pipe 1, the elastic member 29 is fixed by being inserted into the drainage port 27 of the Japanese-style toilet and / or the existing drainage pipe 7, and the adhesive 28 or the like.
