Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piping connection for a floor of a sanitary room, which is used for connecting between the floor pan top and the floor concrete by piping when constructing a unitized sanitary room in a building frame. It is related to the structure of the section.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 9, a drainage connection port 1'communicating with a drainage main under a floor concrete 2 has been raised up above the floor concrete 2 so that the floor concrete 2
The above-mentioned drainage connection port 1'is inserted through the through hole 4'of the floor pan 3 installed on the floor pan 3, and a sealing material 5 such as a silicone sealing material is applied to the periphery of the through hole 4'to seal the floor pan 3
A drain pipe from a washbasin, a toilet bowl, etc. is connected to the drainage connection port 1'on the above.

[0003]

By the way, in the above-mentioned conventional example, the through hole 4'is provided for the leakage of water from the floor pan 3.
Sealing is performed only with the sealing material 5 applied to the periphery of the sealing material 5, and only the reliability of the sealing material 5 is relied upon. Therefore, there is a problem that water leakage due to seal breakage occurs due to long-term use.

The present invention has been made in view of the above points, and it is an object of the present invention to perform construction so that water does not leak from the floor pan even after long-term use.

[0005]

In order to solve the above problems, the structure of the pipe connecting portion of the floor of the sanitary room of the present invention is
Sanitary room 7 on floor concrete 2 of building frame 6
The floor pan 3 is disposed, the drainage connection port 1 communicating with the drainage main pipe 8 is exposed on the floor concrete 2, and the insertion hole 4 is formed in the floor pan 3 so as to correspond to the drainage connection port 1. The tubular portion 10 projecting downward of the member 9 is inserted into the insertion hole 4 of the floor pan 3 and the tubular portion 10 is inserted into the drainage connection port 1, and the flange 11 projecting to the outer periphery of the drainage port member 9 is attached to the floor pan 3. The flange 11 is attached to the floor pan 3, and the sealing material 5 is applied to the peripheral edge of the flange 11. To do. By doing so, it is possible to prevent water leakage from above the floor pan 3 by the close contact of the flange 11 to the upper surface of the floor pan 3 and the sealing by the sealing material 5, and from the top of the floor pan 3 even after long-term use. Water leakage can be reliably prevented.

Further, a recess 12 is formed on the periphery of the insertion hole 4 of the floor pan 3.
It is also preferable that the flange 11 of the drainage port member 9 is housed in the recess 12 and the flange 11 is abutted against the bottom surface of the recess 12 for attachment. In this case, even when the drain port member 9 is mounted on the floor pan 3, even if the flange 11 is mounted, the flange 11 can be housed in the recess 12 and mounted, and the tile 13 is attached to the floor pan 3 without any harmful effect.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION A drainage pipe 14 is inserted through a floor concrete 2 of a building frame 6 as shown in FIG. 3, and a drainage connection port 1 at an upper end of the drainage pipe 14 is projected from an upper surface of the floor concrete 2. There is. The drainage pipe 14 is inserted into a through hole 15 drilled in the floor concrete 2 and fixed with a mortar 18. The drain pipe 14 communicates with the drain main pipe 8. As shown in FIG. 4, the drainage port member 9 is formed by providing a disk-shaped flange 11 on the outer periphery of the cylindrical portion 10, and the flange 11 is formed with a plurality of mounting pilot holes 16. The flange 11 may be integrally formed with the tubular portion 10, or the separately formed flange 11 may be integrated with the tubular portion 10 by welding. The floor pan 3 of the sanitary room 7 is formed with an insertion hole 4, and a recess 12 is formed in the peripheral edge of the insertion hole 4 and is recessed downward.
Is provided all around.

With the floor pan 3 installed on the floor concrete 2, the drainage connection port 1 and the insertion hole 4 of the floor pan 3 correspond to each other, and the cylindrical portion 10 below the drain port member 9 is inserted from above the floor pan 2. It is inserted through the hole 4 and the tubular portion 10 is inserted into the drainage connection port 1 for connection. When connecting the cylindrical portion 10 to the drainage connection port 1, an adhesive agent is used for connection if necessary. With the drainage member 9 connected to the drainage connection port 1, the flange 11 is housed in the recess 12 of the floor pan 3, the flange 11 is brought into contact with the bottom surface of the recess 12 and is inserted into the mounting pilot hole 16 of the flange 11. A screw tool 17 such as a screw is screwed into the floor pan 3 as shown in FIG. As a result, the flange 11 becomes the recess 1
The floor pan 3 is attached so as to be in close contact with the bottom surface of the floor pan 3 so as not to leak water from above the floor pan 3. Further, when the screw tool 17 is screwed in, the mounting pilot hole 16 is filled with the sealing material 5 such as a silicon sealing material, and leakage of water from the portion into which the screw tool 17 is screwed is prevented.

After fixing the flange 11 with the screw tool 17, a sealing material 5 such as a silicon sealing material is applied along the outer periphery of the flange 11 to seal between the outer periphery of the flange 11 and the bottom surface of the recess 12. Will be done. Since the drain port member 9 can be attached so that the flange 11 is brought into close contact with the bottom surface of the recess 12 to prevent water leakage, the insertion hole 4 provided in the floor pan 3 may be formed larger than the diameter of the tubular portion 10. Yes, drain connection 1 as shown in FIG.
Even if the center C1 and the center C2 of the insertion hole 4 are misaligned (dimension α in FIG. 5), the drain port member 9 can be attached. After attaching the drainage member 9 in this way,
If necessary, the floor pan 3 may be attached to the cylindrical portion 10 above the drainage member 9.
The upper drain is connected. Further, the mortar 18 is loaded into the recess 12 with the flange 11 attached so as to be housed in the recess 12, and the tile 13 is attached to the upper surface of the floor pan 3 to finish the floor as shown in FIG.
