Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet installation structure in which a faucet is attached to a wall, and in particular, a faucet used when a pipe for water supply or hot water supply is installed in a building using a sheath pipe. Regarding installation structure.

[0002]

2. Description of the Related Art A sheath pipe construction method is known as a construction method for arranging a pipe for supplying water or hot water in a building. In this sheath pipe construction method, as shown in FIG. 5, the bellows-shaped sheath pipes 6, 7 are drawn between the water supply header 4 or the hot water supply header 5 and the faucets 9, 11, etc.
A tube for supplying water or hot water is passed through the inside of the sheath pipe.

In FIG. 5, the water from the water source pipe 1 is supplied to the water heater 2, and hot water is supplied from the hot water pipe 3 to the hot water header 5.
Supplied to Further, water is supplied from the water supply source pipe 1 to the water header 4.

A water sheath 6 connected to the headers 4 and 5,
A water supply tube and a hot water supply tube are inserted into the hot water sheath pipe 7, and the mixed water faucet 9 of the bathroom 8 and the mixed water faucet 1 of the washbasin 10 are inserted.
1. The tube is connected to a kitchen faucet (not shown) or the like.

This mixed faucet 9 has its mounting legs 12, 13
Is fixed to the wall. A conventional example of the installation structure of the faucet 9 will be described with reference to FIGS.

A box 22 is installed on the back side of the wall 20 having a wall hole 21, and the sheath pipe connection port 2 at the bottom of the box 22 is installed.
The sheath tube 6 or 7 is connected to 3 by a sheath stop nut 24. A tube 16 for water supply in the sheath pipe 6 or 7
Alternatively, a tube 17 for hot water supply is inserted. The tip of the tube 16 or 17 is connected to the rear end of the elbow 25 by a split ring 18 and a slide ring 19. The tip of the elbow 25 is projected forward from the elbow drawing opening 26 of the box 22.

As shown in FIG. 8, a female screw is formed on the inner peripheral surface of the opening 26, and a fixing ring 27 having a male screw on the outer peripheral surface is screwed into the opening 26. The ring 27 is a stopper 28 provided in the box 22.
Is screwed into the opening 26 until it abuts. The tip of the elbow 25 projects from the wall 20 through this fixing ring. A male screw is provided on the outer peripheral surface of the tip portion of the elbow 25, and a decorative ring 29 is screwed onto the male screw.

The right side water supply elbow 25 (25R) and the left side hot water supply elbow 25 provided on the wall 20 as described above.
The mounting legs 12 and 13 are screwed into (25 L) as shown in FIG. The mounting legs 12 and 13 are removed from the body portion 9A of the mixed faucet 9, and the mounting legs 12 and 13 are separately screwed into the elbows 25R and 25L. At this time, the male screw 12 at the tip of each mounting leg 12, 13
A seal tape is wound around the outer circumferences of a and 13a. After adjusting the angles of the mounting legs 12 and 13 so as to have a C-shape when viewed from the front, the body portion 9A of the mixing faucet 9 is
Each mounting leg 12, 1 with a union nut (not shown)
Connect and fix to 3. In this case, each union nut is first lightly tightened, the body portion 9A is leveled, and then each union nut is fully tightened.

[0009]

The above-mentioned conventional faucet installation structure has the following problems.

Although the sealing tape is wound around the male screws 12a and 13a at the tips of the mounting legs 12 and 13, there is concern about the reliability of watertightness.

The union nut is lightly temporarily tightened and the body part 9A is leveled out. It is difficult and difficult to level the work.

The tip of the elbow 25 needs to protrude from the wall 20 by a specified length. Therefore, if the wall 20 has a different thickness, it is necessary to use an elbow having a different horizontal portion length in accordance with the thickness.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems of the prior art and to provide a faucet installation structure which is easy to construct and which requires only one elbow.
