[Problems to be Solved by the Invention] The conventional pipe joint positioning device described above consists of a first housing, a second housing, and a cylindrical member, and the first housing is fixed to a wall surface. The tube positioning device is installed in a wall, and this wall may be inside a double wall consisting of a wall plate on the indoor side and a wall plate on the outside.

Therefore, it is necessary to install the pipe joint positioning device after installing the indoor side wall plate, and then install the outside wall plate. That is, it is necessary to install a pipe joint positioning device between the double wall plates. Since the construction work for installing the wall plate and the work for installing the pipe joint positioning device are performed by different contractors, there is a problem that it is not possible to continuously install the wall plate on the indoor side and the wall plate on the outside.

The invention allows these double wall plates to be provided in succession. That is, the object of the present invention is to provide a piping/installation method for water faucets and gas faucets that can be installed inside a double wall plate even after it has been installed.

[Means for Solving the Problems] The present invention provides a method for attaching a water faucet or a gas faucet to a double wall/floor having an indoor wall/floor plate and an outer wall/floor plate,
In this method of piping to a water faucet or gas faucet, first, a flexible pipe runs inside the double wall/floor, and a faucet/gas faucet is installed on the wall/floor board on the indoor side. There is a hole for installation, and the tip of a flexible pipe is near this hole. Penetrate the faucet installation hole and protrude this tip into the room.Secondly, connect the pipe joint of the water faucet/gas faucet joint described below to this flexible tube tip, and connect the faucet/gas faucet to the The plug joint has a pipe joint part for connecting a flexible pipe at one end, a plug joint part for connecting the water faucet/gas faucet at the other end, and the outer periphery of this other end. A flange whose length in the longitudinal direction is longer than the diameter of the water faucet/gas faucet mounting hole and whose length in the width direction perpendicular to the longitudinal direction is shorter than the diameter of the hole is provided on the surface. The water faucet/gas faucet joint has a thread formed on the outer circumferential surface up to the end, and a flange type nut that is screwed to this male thread. Without screwing the flange-type nut to the faucet/gas faucet joint, the longitudinal direction of the flange of the faucet/gas faucet joint is inclined from the faucet/gas faucet mounting hole to the wall board/floorboard surface on the indoor side. Insert the faucet/gas faucet joint so that the other end of the faucet/gas faucet joint protrudes slightly. The screw is connected to the male thread of the water faucet/gas faucet, and further tightened and fixed with a flange type nut using a tool. Sixth and finally, the water faucet/gas faucet is connected to the faucet joint part of the faucet/gas faucet joint. This is a piping and installation method for water faucets and gas faucets.

As explained above, according to the piping/installation method for faucets and gas faucets according to the present invention, a faucet or gas faucet can be installed even after a double wall is provided.

[Example] An example of the piping/installation method for water faucets and gas faucets according to the present invention will first be described with reference to FIG. FIG. 1 shows a water faucet/gas faucet joint, with the section above the center line being a sectional view, and the section below this being a front view.

The water faucet/gas faucet piping/installation method of this embodiment uses the faucet/gas faucet joint shown in FIG. 1, which will be described next, so this faucet/gas faucet joint will be described in detail.

The faucet/gas faucet joints are installed between the inner wall plate 2o on the indoor side and the outer wall plate 30 on the outside, and holes 21 are drilled in the inner wall plate 20 at the mounting positions of the faucet/gas faucet joints. Fix it here. This wall board can be made of, for example, wooden plywood, gypsum board,
Alternatively, it may be made of a plastic plate or the like. In FIG. 1, the faucet φ gas tap joint is an elbow type in which the flow direction changes by 901', but there is also a socket type in which the flow direction does not change.

The plug joint main body 1 has a cylindrical shape and an elbow type, and one end has a structure for connecting a flexible pipe, and the other end has a thread 14 on the outer peripheral surface and a plug joint part, that is, on the inner peripheral surface. A female thread 13 for water faucets and gas faucets is formed.

The flexible tube connected to this one end is, for example, a plastic tube or a bellows-type flexible metal tube, and is the plastic tube 6 in this embodiment. The structure φ portion of one end of the plug joint body 1 for connecting the plastic pipe 6 is as follows.

That is, one end of the plug joint main body 1 is a double cylinder, and the plastic pipe 6 is fitted into the inner cylindrical part 11, and the nut is screwed into the outer cylindrical part 12. The inner cylindrical portion 11 has an inner circumferential surface that has the same inner diameter as the inner circumferential surface of the middle portion of the plug joint body 1, and a jagged part is formed on this outer circumferential surface to which the plastic pipe 6 fits and prevents its removal. be.

The end of this plastic pipe 6, that is, the plug joint body 1
An annular lock ring 3 is attached to the outer peripheral surface of the portion that fits into the inner cylindrical portion 11 of one end.

The outer cylindrical portion 12 at one end of the plug joint body 1 forms a thread on its outer circumferential surface, and this inner circumferential surface is a tapered inner circumferential surface whose diameter increases as it goes outward. A nut 2 is threadedly connected to the male thread on the outer peripheral surface. The nut 2 has a female thread on its inner circumferential surface and a collar at the end of its inner circumferential surface. This nut 2
When screwed onto the outer cylindrical portion 12 at one end of the plug joint body 1, the collar of the nut 2 presses the end surface of the lock ring 3, and the lock ring 3 presses against the outer peripheral surface of the plastic tube 8.

A resin cover is further attached to the outer peripheral surface of the nut 2 and also covers the plastic pipe 6.

One end of the plug joint body 1 explained above and the lock ring 3
and the nut 2 constitute a pipe joint portion of the plastic pipe 6.

First, the flange 4 is screwed to the external thread 14 formed on the outer peripheral surface of the other end of the plug joint body 1. The flange 4 is a rectangular plate-shaped flange 4, as shown in FIGS. 2a and 2b, or a plate-shaped flange 4 in which the short side of the rectangle is an arc.

In any shape of the flange 4, the length in the longitudinal direction is longer than the diameter of the hole 21 of the inner wall plate 20, and the length in the width direction perpendicular to the longitudinal direction is shorter than the diameter of the hole 21. A through female threaded hole 41 is provided in the center of the flange 4 to be screwed to the plug joint body 1 and the male thread 14 at the other end.

The flange 4 may have a normal plate shape as shown in FIGS. 2a and 2b, but it may also have a stepped surface so that the surface of the flange 4 on the inner wall plate 20 side can be fitted with a spigot as shown in FIG. 1. In this way, the center of the hole 21 in the inner wall plate 20 and the center of the other end of the plug joint body 1 will not deviate significantly.

A blind hole 42 is bored near the female threaded hole 41 approximately on the center line in the longitudinal direction of the flange 4, and this blind hole 42 is a blind hole into which a tool is inserted to rotate the flange.

The flange 4 described above has a female threaded hole 41 and is threadedly connected to the plug joint body 1 and the male thread 14 at the other end, but these may be integrated.

The flange 4 is threadedly connected to the male thread 14 at the other end of the plug joint main body 1, but in order to prevent the flange 4 from coming off from the male thread I4 to the middle part of the plug joint main body 1, It is preferable to form a stopper 15 on the outer circumferential surface.

After the flange 4 is screwed to the male thread 14 at the other end of the plug joint body 1, the flange type nut 5 is screwed to the male thread 14. That is, the flange 4 is screwed to the other end on the intermediate side of the plug joint body 1, and the flange type nut 5 is screwed to the other end on the end side.

As shown in FIG. 3, the flange type nut 5 has a circular ring shape and has a female threaded hole 51 in the center thereof which is threadedly connected to the male thread 14 at the other end of the plug joint body 1. Furthermore, as shown in the cross-sectional view of FIG. 4, the flange-type nut 5 has a circumferential groove 8 bored in one side, the wall side, and a rubber or plastic O-ring is embedded in this groove 8. It's crowded. Blind holes 52 are made at four locations on this surface and the other surface, a tool is inserted into the blind holes 52, and the flange type nut 5 is rotated to be screwed to the other end of the plug joint body 1 and tightened firmly.

The flange type nut 5 may be rotated by making it into a hexagonal shape, a hexagonal shape, or a shape having two parallel planes, and rotating it with a spanner or the like, instead of making it circular and having a blind hole 52 formed therein. In this case, the blind hole 52 is unnecessary.

Further, in order to increase the axial length of the female threaded hole 51 of the flange-type nut 5, the surface of the flange-type nut 5 on the inner wall plate 20 side may be a stepped surface as shown in FIG.

Next, the method, operation, and sequence for attaching the faucet/gas faucet joint used in this embodiment described above to the inner wall plate 20, that is, the piping/installation method for the faucet/gas faucet will be explained.

First, before installing the water faucet/gas faucet joint, the inner wall plate 20 and the outer wall plate 30 are already provided, the inner wall plate 20 has a hole 21, and these double walls A plastic pipe 6 and this cover 7 are piped inside to the vicinity of the hole 21.

First, the plastic pipe 6 and its cover 7 are pulled out into the room through the hole 21, and connected to the pipe joint part of the faucet/gas faucet joint as previously described.

Second, the plastic pipe 6 and the pipe joint part of the water faucet/gas faucet joint to which this cover 7 is connected, and the other end of the faucet joint main body 1 with the flange 4 screwed, are inserted 2' into the hole 21. Insert into the wall. At this time, since the length of the flange 4 in the longitudinal direction is longer than the diameter of the hole 21, the longitudinal direction of the flange 4 needs to be slanted rather than parallel to the surface of the inner wall plate 20.

Third, with the flange 4 in contact with the outer surface of the inner wall plate 20, the male thread 14 at the other end of the faucet/gas faucet joint main body 1 is projected from the inner surface of the inner wall plate 20 toward the indoor side. Let it be,
Connect the flange type nut 5 to the male thread 14 at the other end of the plug joint body 1.
The inner wall plate 20 is clamped between the flange-type nut 5 and the flange 4 by screwing them together and further screwing them in with a tool.

Here, the contact surface of the flange 4 with the inner wall plate 20 may be made uneven so that the flange 4 does not rotate.

The installation of the faucet/gas faucet joint to the inner wall plate 20 and the piping to this are completed, and the female thread 13 for the faucet/gas faucet is attached to the indoor side surface of the inner wall plate 20, that is, the indoor wall surface. After this, the water faucet or gas faucet can be installed and fixed by screwing in, and the piping and installation of the faucet and gas faucet are completed.

In this case, the water faucet/gas faucet is of a male thread type, and a female thread 13 is provided on the indoor wall surface. However, if the faucet/gas faucet is a female screw type, it is necessary to have the male screw protruding from the interior wall surface, and the configuration is as follows.

That is, only the other end of the faucet joint body 1 is different from the water faucet/gas faucet joint described previously; this other end does not have a female thread for a faucet/gas faucet on the inner peripheral surface; A surface is simply a channel. The outer circumferential surface of the other end has a male thread for a female water faucet/gas faucet threaded at the endmost part, and a thread 14 is formed next to this. By using this type of faucet joint body, we can create a faucet/gas faucet that can be used even if the faucet e-gas faucet has a female thread type.
It is a gas valve joint.

Next, if the flange 4 is a water faucet/gas faucet joint in which the flange 4 is threadedly connected to the faucet joint body 1, the attachment position of the flange 4 to the faucet joint body 1 can be adjusted. By performing this adjustment, even if the thickness of the inner wall plate 20 changes somewhat, the flange type nut 5 can always be threadedly connected to the plug joint body 1, and furthermore, the surface of the flange type nut 5 and the plug joint body 1 can be The side end surfaces can be aligned.

The example explained above is about the piping and installation method for water faucets and gas faucets, but in the piping and installation method for faucets and gas faucets in this example, the operations, order, and procedures are reversed to those in this example. For example, it is also possible to remove water faucets and gas faucets that have already been piped and installed.

[Effects of the Invention] As explained above, the piping of water faucets and gas faucets according to the present invention
With the installation method, even after installing a double wall, it is possible to pipe and install water faucets and gas faucets without destroying the wall or making larger holes than necessary.
