Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting a defecation pipe connected to sewage or the like and an outlet of a defecation passage of a toilet via a drainage flange.

[0002]

2. Description of the Related Art A conventional structure for connecting a defecation pipe, which is connected to sewage or the like, and an outlet of a defecation passage of a toilet bowl, is as shown in a vertical sectional view of FIG. As shown in the figure, a defecation pipe 2 which is in communication with a sewer pipe or the like when a building body is constructed is vertically embedded in a floor 1 of a toilet room.
And, on the inlet side opening to the toilet room of the defecation pipe 2,
The tubular portion 3a of the drainage flange 3 is fitted inside. The flange portion 4 of the drainage flange 3 is fixed to the floor 1 via a mounting screw 5.

On the upper surface of the flange portion 4 of the drainage flange 3, a gasket 6 made of unvulcanized butyl rubber that is self-adhesive and is compositionally deformable is placed. The outflow port 9 of the defecation passage 8 formed integrally with the toilet bowl 7 is provided with the defecation pipe 2
It is placed in contact with the gasket 6 made of the unvulcanized butyl rubber so as to be aligned with the inflow side.

Further, a T bolt 10 for fixing a toilet is fitted and mounted on the drainage flange 3 and protrudes upward. By inserting the T-bolt 10 into the upper surface side of the leg 11 of the toilet bowl 7 and screwing and fastening the nut 12, the toilet bowl 7 is fixed and the outlet 9 of the defecation passage 8 and the inlet of the defecation tube 2 are connected. I am trying to establish a communication connection. In addition, 13 is a nut 1
2 is a cosmetic cap for concealing the bolt 2 and the bolt 10.

[0005]

As described above, in the conventional drainage flange 3 connection structure, the defecation passage 8 of the toilet 7 is provided.
A gasket 6 made of unvulcanized butyl rubber is interposed between the outlet 9 and the drainage flange 3 to maintain watertightness.

By the way, the unvulcanized butyl rubber gasket 6 is a self-adhesive and plastic material. Therefore, when the toilet bowl 7 needs to be replaced after the toilet bowl 7 has been constructed and then the building is remodeled, the unvulcanized butyl rubber gasket 6 causes the flange portion 4 of the drainage flange 3 and the toilet bowl 7 to defecate. It has a drawback that it remains adhered around the outflow port 9 of the passage 8 and it is difficult to remove it. This is because the unvulcanized butyl rubber has a strong self-adhesive property, and when the toilet bowl 7 and the drainage flange 3 are watertightly joined, the unvulcanized butyl rubber spreads and adheres in a large area.

[0007]

SUMMARY OF THE INVENTION The present invention has been made by improving and removing the conventional problem in view of the above problems, and does not provide a connecting structure for a toilet bowl and a defecation pipe in which the toilet bowl and the drainage flange can be easily disassembled. It is what

The means adopted by the present invention in order to solve the above-mentioned problems are as follows:
In a case where the outlet of the defecation passage of the toilet is connected via a drainage flange, the upper and lower two layers of unvulcanized butyl rubber and vulcanized rubber are provided between the drainage flange and the outlet of the defecation passage of the toilet. A connection structure between a toilet bowl and a defecation pipe, characterized in that an unvulcanized butyl rubber is bonded to the outlet side of the defecation passage of the toilet bowl by arranging a gasket.

[0009]

The gasket used in the present invention comprises upper and lower two layers of unvulcanized butyl rubber and vulcanized rubber. Then, at the time of construction, unvulcanized butyl rubber is joined to the outlet side of the defecation passage of the toilet bowl.

As described above, since the gasket has an upper and lower two-layer structure of unvulcanized butyl rubber and vulcanized rubber, in the state of being used as a gasket, the unvulcanized butyl rubber portion has self-adhesive force in addition to pressure bonding. Even if the surface properties of the toilet bowl side are uneven such as unevenness due to the addition of the adhesive force due to the above, it is possible to secure an extremely high sealing property. Further, in the vulcanized rubber portion, only the sealing property by pressure bonding is secured, and since it does not have self-adhesiveness, disassembly work etc. after assembly is easy.

In addition to this, by joining unvulcanized butyl rubber, which is a plastic material, to the toilet side with self-adhesiveness,
The unevenness of the end surface of the outlet of the defecation passage can be absorbed by the unvulcanized butyl rubber portion, and excellent sealing properties can be obtained.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described below with reference to the embodiments shown in the drawings. The same reference numerals as in the conventional case are the same members. FIG. 1 is a vertical cross-sectional exploded perspective view showing a connecting portion between a toilet bowl 7 and a defecation tube 2 according to an embodiment of the present invention. As shown in the figure, in this embodiment, an annular gasket 14 disposed between the drainage flange 3 and the toilet 7 is provided with two layers, an unvulcanized butyl rubber 15 and a vulcanized rubber 16, which are upper and lower layers. It has a structure. As the vulcanized rubber 16, a rubber material such as natural rubber, ethylene propylene rubber or butyl rubber can be applied.

Then, for the construction, the vulcanized rubber 16 is placed in the annular recess 3b of the drainage flange 3 attached to the floor 1, and the unvulcanized butyl rubber 15 is set on the drainage flange 3. Do it. Next, the outflow port 9 of the defecation passage 8 of the toilet 7 is located above the defecation pipe 2, and the T-bolt 10 attached to the drainage flange 3 is mounted as in the conventional case.
And the nut 12 may be used to fasten the toilet bowl 7.

By fastening the toilet 7, the unvulcanized butyl rubber 15 and the unvulcanized butyl rubber 15 of the upper and lower two layers of the gasket 14 have a self-adhesive force in addition to the pressure. Join. Therefore, even if there is unevenness such as unevenness on the surface texture of the ceramic urinal 7 side fired at a high temperature, the unvulcanized butyl rubber 1 which is a plastic material
5 absorbs the non-uniformity of the surface properties, and it is possible to secure an extremely high sealing property.

Further, the vulcanized rubber 16 portion only secures the sealing property by pressure bonding and has no self-adhesive property, and therefore disassembly work with the drainage flange 3 is easy. Furthermore,
The unvulcanized butyl rubber 15 is disposed only on the upper end surface of the vulcanized rubber 16 with a small thickness, and has a small adhesive area with the toilet bowl 7 side. Since it does not spread on the side, the vulcanized gum 16 side can be gripped and easily separated from the toilet bowl 7 side after construction. That is, the toilet 7 can be easily replaced.

By the way, the present invention is not limited to the above-mentioned embodiment, and for example, the size and thickness of the gasket 14, the ratio of the thickness of the unvulcanized butyl rubber 15 to the vulcanized rubber 16 and the like can be appropriately changed. Is.

[0017]

As described above, according to the present invention,
A gasket composed of upper and lower two layers of unvulcanized butyl rubber and vulcanized rubber was used.The unvulcanized butyl rubber side was joined to the outlet side of the defecation passage of the toilet and the vulcanized rubber side was joined to the drainage flange. Therefore, in the unvulcanized butyl rubber part, in addition to pressure bonding, adhesive force due to self-adhesive force and plastic deformation action are added, and even if there is unevenness such as unevenness on the surface property of the toilet side, it is absorbed and adheres. It is possible to secure a high sealing property.

In the vulcanized rubber portion, only the sealing property by pressure bonding is ensured and there is no self-adhesiveness. In addition, the unvulcanized butyl rubber, which is a plastic material, is only placed on the upper end surface of the vulcanized rubber, and the adhesion area with the toilet side is small, and the unvulcanized butyl rubber spreads on the toilet side during construction. Since there is no such a case, it is possible to easily peel off the vulcanized gum from the toilet side by grasping the vulcanized gum after the construction. In other words, a structure that ensures a high sealing property in the installed state and that allows the gasket to be easily separated when replacing the toilet bowl,
This makes it easy to replace the toilet bowl.
