Although 1 is embedded with the filler 12, the structure is not particularly limited. The shape of the newly installed reinforcing bar 17 is not particularly limited as long as it is housed in the non-removal portion 11 of the Japanese-style toilet, does not buffer the connection pipe 1, and is configured so that both ends are hooked on the existing floor base portion 10. FIGS. 3- (b), (c) and (d) show one example. Further, the number of the newly installed reinforcing bars 17 is not limited to one, and two or more reinforcing bars 17 may be used as long as they can be accommodated in the non-removal portion 11 of the Japanese style toilet.

As shown in FIG. 4, a cushioning material 18 is inserted between the non-removing portion 11 and the filling material 12 of the Japanese-style toilet buried. The buffer material 18 to be used may be used in combination of two or more kinds as long as it can absorb expansion and contraction during curing of the filler material 12, and is not particularly limited. Also, in the illustrated example,
Although the cushioning material 18 is treated on the entire surface of the non-removal portion 11 of the Japanese-style toilet, partial treatment may be performed as long as the expansion and contraction during curing of the filler 12 can be absorbed, and the construction structure is not particularly limited.

As shown in FIG. 5, a floor finishing section 9 and a floor base section 10 above the toilet bowl 3 of the Japanese style toilet bowl and around the Japanese style toilet bowl 2 are provided.
On the other hand, a connection pipe insertion port 5 is provided in the toilet bowl 3 of the Japanese style toilet, the connection pipe 1 is inserted from above the connection pipe insertion port 5, and the connection pipe insertion port 20 is inserted from above the Japanese style toilet 2. The sanitary fitting 4 is attached to the connection pipe 1 while inserting the connection pipe 1 into the connection pipe insertion port 20 of the floor plate 19 provided. The shape of the floor plate 19 is suitable to be substantially the same as the removing portion so that the floor plate 19 can be placed without a gap. However, as long as the shape can sufficiently support the sanitary facilities 4, it is particularly preferable. Not limited. The material is preferably a rigid body such as an iron plate capable of sufficiently supporting the sanitary facilities 4, but is not particularly limited as long as the sanitary facilities 4 can be sufficiently supported, and may also have a finish. In the illustrated example, the floor plate 19 is 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 step with the existing floor finishing portion 9 is eliminated, and the user does not trip and is safe, but the construction structure is not particularly limited.

As shown in FIG. 6 (a), when one floor plate 19 is used, the floor plate 19 is always provided with the connection pipe insertion port 20, and the connection pipe insertion port 2 is provided.
The shape of 0 is not particularly limited as long as it is equal to or larger than the outer diameter of the connection pipe 1. Also, as shown in FIG.

The floor plate support 21 to be used needs to support the floor plate 19, and is therefore preferably made of a material having high rigidity, such as carbon steel, but is not particularly limited as long as the floor plate 19 can be supported. It should be noted that the number of the support portions 21 is not limited to one, and if two or more are used, more sufficient support is possible.

As shown in FIG. 8, the height of the floor plate 19 can be adjusted, so that the height and horizontal adjustment of the floor plate 19 can be adjusted even if the installed floor surface is uneven. It can be easily performed and the construction period can be shortened. Regarding the height adjustment function of the floor plate 19, even if the floor plate 19 integrated with the height adjustment function is used, another member that can adjust the height 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 floor surface on which the floor plate 19 is placed is less uneven. Also, such height adjustment function,
If not less than one, and two or more are used, more accurate height adjustment and horizontal adjustment are possible. In the illustrated example, a through hole is provided in the floor plate 19, and a floor plate leg member 22 having a female screw is attached so as to cover the through hole.
The structure is such that the height adjusting leg 23 subjected to the male screw processing can be screwed in the vertical direction. The height adjustment and the horizontal adjustment can be performed by the screwing degree of the height adjustment leg 23, but 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 adjustment leg 23 in this example needs to support the floor plate 19, it is desirable that the height adjustment leg 23 has high rigidity, such as carbon steel, but is not particularly limited as long as the floor plate 19 can be supported.

As shown in FIG. 9, a floor plate finishing material 24 is provided above the floor plate 19, and the connection pipe 1 is provided.
