In the figure, reference numeral 9 indicates a rain cover, which is composed of a waterproof sealing plate 18 and one covering plate. Holes 20 and 21 are bored in the center of the sealing plate 18 and the covering plate 19, and Screw insertion holes 22.23 are also drilled, and when the seal plate 18 is inserted into the cover plate 19 having the forward protruding edge piece 24 on the outer periphery, the holes 20.21 communicate with each other, and the screw insertion holes 22.23
are now communicating.

In the figure, reference numeral 29 denotes a fixture, and in the embodiment shown in FIG. 9, the fixture 29 has the following structure.

That is, as the fitting 29, for example, a protruding piece 32 is provided on the opposite end of a split ring body 31 so as to be opposed to each other, the split ring body 31 is slidably fitted onto the gas pipe 3, and the protruding piece 32 is attached at an arbitrary position. Bolt 33 or bolt 33 and nut 38
The split ring body 31 is fixed to the gas pipe 3 by tightening with.

In this case, a hole 34 is drilled in one of the opposing protrusions 32 and a tapped hole 35 is bored in the other, and the bolt 33 is tightened, or a hole 34 is bored in both protrusions 32 and the bolt 33 is tightened.
- It may be tightened with a nut 38.

Here, a mounting protrusion 36 protrudes partially or over the entire circumference from the outer periphery of the split ring body 31, and a screw hole 37 is bored in the mounting protrusion 36.

As shown in FIG. 12, a mounting protrusion 36 is provided on the outer periphery of the nut body 39 partially or over the entire periphery.
In this case, the straight pipe 3 of the pipe 3
A male thread 40 is cut in C, and the nut body 39 is screwed into the pipe 3 so as to be movable in the longitudinal direction.

As in each of the above embodiments, the fitting 29 is fixed at any position on the pipe 3 (in the illustrated embodiment, the straight pipe 3C), and with the outlet main body 4 attached to the pipe 3, the tip of the pipe 3 and the outlet The main body 4 is inserted into the through hole 2, and in this state, the rain cover 9 covering the rear opening of the through hole 2 is attached to the mounting protrusion 36 of the fixture 29 with a fixing device 10 such as a screw.

In this case, a fixing device 10 such as a screw is inserted into the hole 20 through the hole 21, and the tip of the fixing device 10 is attached to the mounting protrusion 36 of the fitting 29.
The rain cover 9 is fixed to the pipe 3 via the fitting 29 by screwing into the screw hole 35 of the rain cover 9.

Of course, the fixing method is not limited to the above-mentioned fixing method, and a bolt may be provided protruding from the fixture 29, inserted into the hole 20, 21, and fixed with a nut.

On the other hand, a case 5 having an outer diameter approximately equal to the diameter of the through hole 2 is inserted into the through hole 2 from the front, the elongated hole 17 and the threaded hole 15 for case attachment are communicated, and a fixing device 8 such as a screw is inserted into the through hole 2 from the front. The case 5 is fixed to the outlet body 4 by being inserted through the elongated hole 17 and screwed into the case mounting screw hole 15.

In the illustrated embodiment, the flange 11 of the outlet body 4 is
Although this is the mounting portion 7 for attaching the mounting piece 6 of the case 5, a portion other than the flange 11 may be used as the mounting portion 7.

In addition, by providing the elongated hole 17 in the mounting piece 6, the outlet body 4 can be attached to the center of the through hole 2 due to construction errors.
Even if the centers of the through holes 2 and 2 do not match, the cylindrical case 5 can be firmly fitted into the inner wall of the through hole 2 by sliding the fixing device 8 such as a screw along the elongated hole 17. The case 5 can be fixed to the outlet main body 4 using the tool 8.

By doing this, the case 5 does not move in the direction perpendicular to the axis of the through hole 2, and the outlet main body 4 also does not move in the direction perpendicular to the axis of the through hole 2.

In the above embodiment, the mounting piece 6 is provided with a long hole 17, but the mounting piece 6 may be provided with a hole or a threaded hole, and the mounting portion 7 may also be provided with a long hole. Elongated holes may be provided in both the mounting piece 6 and the mounting portion 7, and the mounting pieces 6 and the mounting portion 7 may be fixed with fasteners 8 such as bolts and nuts.

By the way, when the rain cover 9 is fixed to the pipe 3 via the fixture 29 with the fixture 10, the cover plate 19 is pressed against the outer periphery of the rear opening of the through hole 2 via the seal plate 18 of the rain cover 9. This prevents rainwater from entering through the through hole 2, and the pipe 3 (in the illustrated embodiment, the elbow 3
Even when a forward external force is applied to the standpipe 3a) or the standpipe 3a), the outlet main body 4 is prevented from moving forward, and as a result, the outlet main body 4 is prevented from jumping forward beyond the through hole 2.

On the other hand, the hook piece 16 of the case 5 corresponds to the outer periphery of the front opening of the through hole 2, and prevents the outlet main body 4 from moving backward.

In the figure, reference numeral 26 denotes a front frame having a lid 27, which is attached to the outlet main body 4 with screws 28.

Note that when the wall 1 is thin, the pipe 3
A screw hole 16 is bored in the outlet main body 4 attached to the tip of the outlet, and the rain cover 9 is attached to the outlet main body 4 using the screw hole 16 with a fixture 10.

In the above embodiment, a gas pipe is used as the pipe, but the pipe may also be a water pipe.

Therefore, in the present invention, as described above, the fitting is fixed to the pipe installed in the through hole drilled in the wall, and the rain cover covering the rear opening of the through hole is fixed with a screw-like fixing device. Since it is attached to the mounting protrusion of the fixture, the rain cover can be reliably mounted without rattling.

That is, since the piping does not move even with a slight external force, the rain cover can be reliably attached, and rainwater can be prevented from entering through the rear opening of the through hole.

Furthermore, even if a large external force is applied to the piping in the forward direction, the presence of the rain cover can prevent the piping from moving forward.

In addition, the fixture is fixed so that it can be moved freely in the longitudinal direction of the pipe, so even if the wall thickness changes, by changing the fixing position of the fixture, it can be installed reliably to accommodate various wall thicknesses. There is an advantage that the rain cover can be attached to the piping via a fitting.

Note that when the split ring body 31 is used as the fitting 29, the fitting 29 can be attached even if the diameter of the pipe 3 is different, and the elbow 3b, which is a part of the pipe 3, can be attached.
Even if the tip of the elbow 3b is inserted into the through hole 2,
It can be attached by tightening the fixture 29.
