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 hot water or water flow pipe disposed under a floor to a faucet attached to a bathroom, a sink, a wash basin, or the like.

[0002]

2. Description of the Related Art Conventionally, hot water and water flow pipes are provided under the floor.
FIG. 3 shows a known example in which the water pipe is raised from a floor plate and connected to a faucet attached to a bathroom, a sink, a sink, or the like. Briefly describing FIG. 3, a resin water pipe 41 provided at the lower portion of the floor plate 40 is provided with a packing 44 at a lower portion of a socket 42 fixed to the floor plate 40 by bending its tip vertically. Via a cap nut 43, a metal water supply pipe 45 is provided above the socket 42, and the cap nut 4 is also connected via a packing 44.
The upper part of the water supply pipe 45 is connected to the lower part of a faucet attached to a bathroom, a sink, a sink, etc., and hot water and water are supplied to the faucet by a water pipe 41, a socket 42 and a water supply pipe 45. Is what you do.

[0003] In the above, the socket must be fixed to the floor plate, and a water pipe and a water supply pipe must be separately connected to the upper and lower sides of the socket. In addition to the troublesome connection work, due to construction errors such as insufficient tightening of the cap nut and deterioration of the packing, there is a high probability that water will leak from the connection to the socket, and the floorboard will be flooded, causing enormous damage. there were.

[0004] Further, since the water supply pipe connected to the upper side of the socket is made of metal, in a humid season such as the rainy season or summer,
Dew condensation easily occurred on the outer surface, and the floorboard was uncomfortable and wet.

[0005]

The problem to be solved by the present invention is to connect a hot water pipe or a water pipe provided under the floor to a faucet attached to a bathroom, a sink, a sink, or the like. Another object is to reduce the occurrence of water leakage and condensation.

[0006]

SUMMARY OF THE INVENTION According to the present invention,
Attach a water faucet to the top plate of the bathroom, sink, wash basin, etc., fix the through fitting to the through hole drilled in the floor plate, and connect the hot water and water flow pipe provided at the bottom of the floor plate to the through fitting watertight. And connected to the faucet.

According to a second aspect, the water pipe is made of a synthetic resin.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. The present invention, as shown in FIG.
A bathroom, a sink or a wash basin (in this embodiment, a wash basin 1) is provided with a back surface along the wall 2 and a faucet 3 composed of a hot and cold water faucet.
A top plate 6 to which the faucet 3 is attached, a cabinet 8 on which the top plate 6 is mounted, and a wash bowl 9 fixed to the front of the top plate 6, and a drain port at the bottom of the wash bowl 9. 1
0 is provided, and the hot and cold water accumulated in the basin 9 is discharged to the outside by the water distribution pipe 11 installed inside the cabinet 8.

Each water pipe 13 for hot and cold water is formed of a polyethylene pipe, a polypropylene pipe or the like made of a synthetic resin which can be easily bent, and is provided below the bottom plate 12 of the wash basin 1 and between the floor plate 14 and the base floor 15. The upstream side is connected to a hot water supply source and a water supply source (not shown), and the downstream side is vertically bent toward the inside of the cabinet 8 and is fixed to an insertion hole 16 formed in a floor plate 14 described later. It is inserted through the through-hole 17.

The faucet 3 has a male screw 4 extending downward.
Is fixed to the top plate 6 by inserting a fixing nut 5 into the male screw portion 4 from the inside of the cabinet 8 below the top plate 6 by inserting the fixing nut 5 into the mounting hole 7 formed in the top plate 6 from above. The water pipe 13 is connected to the lower part of the male screw part 4 so as to supply hot water and water to the faucet 3.

As shown in FIG. 2, the through-hole 17 is formed by connecting a fixing member 25 to a substantially cylindrical support member 18 from above. The support member 18 has a flange portion 19 formed on the entire upper outer peripheral edge so as to face the periphery of the insertion hole 16 of the floor plate 14 vertically, and a screw 21 is inserted from above the floor plate 14 into a screw hole 20 formed in the flange portion 19. The fixing member 25 is screwed from above in the vertical direction at the center, and the insertion opening 2 has a size and a shape.
2, the insertion opening 22 has a female screw portion 23 formed on the inner peripheral surface, and a through hole 24 through which the water pipe 13 is inserted is vertically formed below the insertion hole 22.

The fixing member 25 has a male screw portion 26 on a lower outer peripheral surface.
Is formed in a cylindrical shape, and a through hole 27 penetrating vertically through the center.
When the packing 28 is mounted between the insertion port 22 of the support member 18 and the water pipe 13 in a state where the water pipe 13 is inserted through the water pipe 13, the male screw portion 26 is screwed to the female screw portion 23 of the support member 18.
The water pipe 13 is supported by the through-hole 17 and is fixed in a watertight manner. The through-hole 17 is water-tightly covered from above by the cover 29 and the sealing member 30 inserted into the water pipe 13.

In order to connect the hot and cold water pipes 13 provided between the floor plate 14 and the base floor 15 to the faucet 3 attached to the top plate 6 of the wash basin 1, firstly, The distal end of the water pipe 13 is raised in the vertical direction, and is inserted from the lower part of the floor plate 14 into a through hole 24 formed in the support member 18 of the through-hole 17 fixed to the floor plate 14. Next, the male screw portion 26 of the fixing member 25 is inserted through the packing 28 from the upper portion of the floor plate 14.
Is screwed into the female screw portion 23 of the support member 18, the water pipe 13 is fixed to the through fitting 17 in a watertight manner, and the through fitting 17 is covered from above by the cover 29 and the sealant 30. Then, if the tip of the water pipe 13 is connected to the bottom surface of the male screw portion 4 of the faucet 3 attached to the top plate 6 of the washstand 1, the connection operation is completed.

[0014]

According to the present invention, a water faucet is attached to a top plate of a bathroom, a sink, a wash basin, etc., a through-hole is fixed to an insertion hole formed in the floor plate, and hot water and water disposed at a lower portion of the floor plate are provided. Was inserted through the through fitting in a watertight manner and connected to the faucet. Therefore, since the hot water and water flow pipes are directly connected to the faucet through the penetrating fittings, there are no connecting points with the penetrating fittings. It reduces the cause of the occurrence and prevents the floorboard and the like from being flooded.

Further, since the water pipe is made of a synthetic resin and a metal water pipe is not used between the water pipe and the faucet as in the prior art, dew condensation may occur in the rainy season, summer season and the like. The floorboard can be kept clean without any.
