[0001]

[Industrial applications]

 The present invention relates to a drainage flange structure for connecting a drainage port of a toilet bowl to a drainage PVC pipe arranged on a floor surface.

[0002]

[Prior art and its problems]

 Conventionally, the structure of the drainage flange is as shown in the vertical sectional view of FIG. 3, and the drainage PVC pipe 4 made of vinyl chloride is previously installed in the floor F of the toilet in a vertical direction in an embedded manner. A floor flange 5 is fixed on the floor surface F on the drainage PVC pipe 4 via a screw 6, and a pipe portion 5b is integrally formed on the floor flange 5. The drainage PVC pipe 4 is fitted into the drainage PVC pipe 4, and the drainage PVC pipe 4 and the pipe portion 5b are sealed with an adhesive, and the bolt 7 is fitted into the flange portion 5a of the floor flange 5, and the flange portion 5a of the floor flange 5 is The screw 6 is screwed, and the drainage port 3 of the toilet bowl 1 is aligned on the fixed floor flange 5 so that the leg portion 2 of the toilet bowl 1 is installed in a cover-like shape. Tighten the nut 8 from above to secure the floor flange 5 and the leg. 2 is connected to, on the further nut 8 wore preparative decorative cap 9. In such a drainage flange structure, there are many variations in the inner diameter of the drainage PVC pipe 4 and the outer diameter of the pipe portion 5b of the floor flange 5. In such a case, the pipe inside the drainage PVC pipe 4 When the portion 5b is fitted, the gap between the two may become large, and in such a case, there is a problem that the sealing property between the two becomes incomplete and water may leak.

In order to prevent water leakage due to such size variation, a drainage flange structure using a soft pipe 10 made of a soft plastic as shown in FIG. 4 may be conventionally used. A soft pipe 10 is mounted in the pipe 4, and a flange portion 10a protruding outwardly from the upper end of the soft pipe 10 is placed on a disc-shaped floor flange 5, and a gasket G made of butyl rubber G is placed on the flange portion 10a. Place the drainage port 3 of the toilet 1 from above, connect the floor flange 5 and the leg 2 of the toilet 1 via the bolt 7, and connect the collar 10a of the soft pipe 10 to the toilet 1. In this structure, the drainage PVC pipe 4 and the soft pipe 10 are watertightly fitted to each other to prevent water leakage. However, since the soft pipe 10 is soft, it is stored or transported. When it is piled up in However, there is a new problem in that this deformation partially causes a portion that does not come into contact with the inner peripheral surface of the drainage PVC pipe 4, which may cause water leakage.

[0004]

[Means for Solving the Problems]

 The present invention has been devised in view of the above-mentioned conventional problems, and an object thereof is to provide a drainage flange structure that does not cause water leakage. The first gist of the present invention is to provide a drainage PVC pipe embedded in a floor surface. In the floor flange fixed to the floor surface with the pipe portion inserted into the pipe, a soft material is interposed between the drainage PVC pipe and the pipe portion. The second gist is that, in a soft pipe made of a soft material that is inserted into a drainage PVC pipe buried in the floor surface, a hard cylinder made of a hard material is fitted inside the soft pipe. Is.

[0005]

[Action]

 In the first aspect, the soft material is interposed between the outer periphery of the pipe portion of the floor flange and the inner periphery of the drainage PVC pipe, so that the inner diameter of the drainage PVC pipe and the outer diameter of the pipe portion of the floor flange are dimensioned. Even if there are variations, it is possible to reliably prevent the occurrence of water leakage by ensuring a tight seal between the two through a soft material. Further, in the second aspect, by inserting the hard tube into the inner circumference of the soft tube, the soft tube can maintain a surely perfect circular state by the hard tube, and The outer periphery reliably contacts the inner peripheral surface of the drainage PVC pipe over the entire periphery, so that a reliable sealing property can be obtained, and leakage of water can be effectively prevented.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a vertical cross-sectional configuration diagram of the drainage flange portion structure of the first embodiment. The same members as those shown in FIG. In FIG. 1, the soft material 11 is externally fitted on the outer periphery of the pipe portion 5b of the floor flange 5 in advance, and in this state, the soft material 11 is attached to the drainage PVC pipe 4 together with the pipe portion 5b. The soft material 11 can be made of, for example, rubber and formed into a tubular shape. The soft material 11 can be securely adhered to the inner peripheral surface of the drainage PVC pipe 4 to secure the sealing property and prevent leakage of water. If the inner diameter of the drainage PVC pipe 4 and the outer diameter of the pipe portion 5b of the floor flange 5 are uneven, if the soft material 11 is fitted onto the pipe portion 5b, It is possible to prevent water leakage by sealing the two in a close contact state in response to the dimensional variation between the two.

In this state, the flange portion 5a of the floor flange 5 is fixed to the floor surface F with the screw 6, and in that state, the gasket G is inserted from above to align the drain port 3 of the toilet 1, To fix the toilet bowl 1 to the floor flange 5 by tightening the nut 8 from above the leg portion 2 of the toilet bowl 1 against the bolt 7 that is erected by engaging the head portion with the flange portion 5a of the floor flange 5. The nut 8 and the bolt 7 can be covered with a decorative cap 9 for cosmetic treatment.

Next, FIG. 2 is a cross-sectional configuration diagram of the second embodiment. In this example, a hard tubular body 12 is fitted in advance on the inner circumference of the soft tube 10 used in the conventional structure shown in FIG. If the soft tube 10 is stored with the hard tube 12 fitted in advance when the soft tube 10 is stored, the soft tube 10 will not be subjected to a load from above when stacked. Can be maintained in a good circular state without being deformed. In this state, the soft pipe 10 is inserted into the drainage PVC pipe 4 with the hard cylinder 12 fitted inside, The outer circumference of the soft pipe 10 can be brought into close contact with the inner circumference of the drainage PVC pipe 4 to prevent water leakage. Even when the soft pipe 10 is inserted into the drainage PVC pipe 4, the hard cylinder 12 is present inside so that it can be fitted easily, and the workability is improved. Since the other structure is the same as that of FIG. 4, the description thereof will be omitted.

[0009]

According to the present invention, in a floor flange fixed to the floor surface, the floor flange includes a pipe portion inserted into the drainage PVC pipe buried in the floor surface, and the pipe flange is fixed between the drain PVC pipe and the pipe portion. Even if the inner diameter of the drainage PVC pipe and the outer diameter of the pipe part of the floor flange vary in size due to the inclusion of the soft material, the soft material is surely sealed between the two, and water leakage occurs. The effect of being able to satisfactorily prevent Further, in a soft pipe made of a soft material that is inserted into a drainage PVC pipe buried in the floor surface, a hard cylinder made of a hard material is fitted inside the soft pipe, so that The body allows the soft pipe to maintain a reliable perfect circular state, and the outer periphery of the soft pipe surely comes into contact with the inner peripheral surface of the drainage PVC pipe over the entire circumference to obtain a reliable sealing property. The effect of favorably preventing the occurrence of water leakage is exhibited.
