Thereafter, the screw 15 is screwed into the threaded portion 21 of the second wall through member 7 from the outdoor side through the screw through hole 16 of the closing portion 12 of the first wall through member 6, whereby the first wall through member 7 is screwed. 6 and the second wall passing member 7 are connected, and the waterproof packings 14a and 14b are pressed against the inner and outer wall surfaces of the outer wall 2 respectively. With the above, the attachment of the wall penetrating tool 1 of the through-the-wall pipe to the installation hole 3 of the outer wall 2 is completed.

The wall passing tool 1 of the first embodiment has a first wall passing member 6 and a second wall passing member 7 which are screwed with a screw 15.
In the future, if it becomes necessary to remove the wall through tool 1 of this through-the-wall pipe, the screw 15
By simply loosening and removing, the wall penetrating tool 1 of the through-wall pipe can be removed from the installation hole 3 of the outer wall 2.

Next, for example, the pipe 4 and the sheath pipe 5 for hot water supply or liquid supply for water supply are passed through the wall passing tool 1 of the through-wall pipe attached to the installation hole 3 of the outer wall 2 as described above. The setting work will be described. The pipe 4 is a cross-linked polyethylene pipe having flexibility, and the sheath pipe 5 through which the pipe 4 is passed is made of a synthetic resin harder than the pipe 4, but a corrugated pipe having excellent flexibility is used. Has been adopted.

The sheath tube 5 is passed, for example, from outdoors to indoors. That is, one end of the sheath tube 5 is passed obliquely upward from the outdoor side into the sheath tube guide 13 of the first wall passing member 6. FIG.
As shown in FIGS. 4A and 4B, the sheath tube guide 13 is provided obliquely through the closing portion 12 such that the indoor end is above the outdoor end. Because
The sheath tube 5 passed through the sheath tube guide 13 from outdoors to indoors passes through the wall passer 1 obliquely upward without being caught by the second wall pass member 16 and rises along the indoor side wall surface of the outer wall 2. As shown in FIG. 1, as shown in FIG. 1, it is forcibly bent to the narrow back space 24 formed by the outer wall 2 and the interior panel 23 of the room and the attic space 26 above the ceiling 25 of the room. It can be installed without causing buckling deformation. The sheath tube 5 that has been arranged is fixed so as not to be displaced by using a U-shaped saddle 27 or the like attached to the outer wall 2 or the like at an appropriate interval.

Next, the sheath pipe 5, which is obliquely penetrated through the wall passing tool 1 and is supported by the sheath pipe guide 13, is connected to the pipe 4 from outside.
Is inserted obliquely upward, whereby the pipe 4 is disposed along the sheath pipe 5. Since the sheath tube 5 is disposed to the required position without being forcibly bent, the pipe 4 passes through the inside of the sheath tube 5 without being forcibly bent and causing buckling deformation. It is guided to a predetermined position. After arranging and fixing the sheath tube 5, FIG.
As shown in (a), at the opening on the outdoor side of the sheath tube guide 13, the gap between the sheath tube 5 and the opening is closed by performing a water stopping process using the caulking material 28. By this water stopping process,
The danger of rainwater or the like entering from outside to inside through the sheath tube guide 13 can be extremely reduced. Note that an O-ring may be interposed between the sheath tube guide 13 and the sheath tube 5 instead of the caulking process, or both of these water stopping processes may be used.

The other end of the sheath tube 5 on the outdoor side is connected to a system adjuster 30 supported by a system adjuster support 29 installed on the outdoor side of the outer wall 2. Piping 4
The adjuster 30 through which the bellows 31 is stretchable
And can expand and contract to a height suitable for the length of the portion of the sheath tube 5 exposed to the outdoors. The pipe 4 is connected via a joint 32 to a male adapter 33 with a pin that receives the lower end of the system adjuster 30. The adapter 33 is connected to a water heater 34 installed outdoors.
The hot water or the like of the water heater 34 is led.

As described above, according to the work of disposing the pipe 4 and the sheath pipe 5 using the wall penetrating tool 1 of the through-wall pipe, the sheath pipe guide 13 is provided obliquely with respect to the outer wall 2. The sheath tube 5 is arranged indoors along the wall surface of the outer wall 2 by passing through. Since the width D along the vertical direction of the first tubular portion 8 and the second tubular portion 17 is formed sufficiently larger than the outer diameter d of the sheath tube 5, the sheath tube 5 is forcibly bent to cause buckling deformation. The first cylinder 8 and the second cylinder 17 are provided with a sufficiently large space S that does not occur.
Can be secured within. Further, by passing the sheath tube 5 through the sheath tube guide 13 provided obliquely with respect to the outer wall 2, the sheath tube 5 can be arranged indoors along the wall surface of the outer wall 2.

Therefore, even in the narrow space behind the outer wall 2 on the indoor side, the sheath tube 5 is not forcibly bent to cause buckling deformation. For this reason, the piping 4 that passes through the inside of the sheath tube 5 and is disposed from outside to inside can be easily disposed without forcibly bending and causing buckling deformation. Furthermore, by pulling the pipe 4 obliquely downward from the outdoor side, the pipe 4 can be easily pulled out with a small resistance using the sheath pipe 5 as a guide as in the case of insertion. The work of updating the pipe 4 when it is deteriorated can be easily performed.

Further, at the position of the wall penetrating member 1 of the through-the-wall pipe, the sheath tube 5 is continuously arranged from the outdoor to the indoor without interruption. For this reason, even if water leaks from the pipe 4 indoors, it is transmitted to the inside of the sheath tube 5 and discharged to the outside, so that there is a low possibility that the water will enter the room indoors. In addition, since the sheath pipe 5 and the pipe 4 penetrate the outer wall 2 and the joint part to the pipe 4 is on the outdoor side of the outer wall 2, even if there is water leakage from the joint part which easily leaks water, there is a possibility of flooding indoors. There is no.

Further, since the sheath pipe guide 13 is provided obliquely through the closing portion 12 so that the indoor side is located above the outdoor side, rainwater and the like pass through the sheath pipe guide 13 obliquely downward. There is almost no risk of intrusion from outside to inside. In addition, since the opening between the sheath tube guide 13 and the outdoor side is subjected to a water stopping process using a caulking material 28 or the like to close the gap between the sheath tube 5 and the opening, there is no possibility of further flooding.

Further, since the first and second flange portions 10 and 19 and the waterproof seals 14a and 14b provided on them respectively have a sandwich structure in which the installation hole 3 is sandwiched from both sides of the outer wall 2 without any gap. The water stopping process can be easily performed, and a plugging process such as a backfilling operation between the installation hole 3 and the wall passing tool 1 can be omitted, so that the workability is good.

In addition, the order of the work of attaching the wall passing tool 1 to the installation hole 3 and the work of arranging the pipe 4 and the sheath pipe 5 indoors may be performed in any order. Further, in the case of a prefabricated house, since the wall passing tool 1 can be attached to the outer wall 2 in advance, in that case, the mounting of the wall passing tool 1 at the construction site is unnecessary, and the installation work can be easily performed. It can be carried out.

Also, since the shape of the wall passing tool 1 as viewed from the front is a long oval shape along the vertical direction and is small,
Since the installation hole 3 provided in the outer wall 2 can also have a similar oval shape when viewed from the front, it is not necessary to provide a large circular hole in the outer wall 2, and the provision of the installation hole 3 reduces the strength of the outer wall 2. Can be suppressed.

Next, the wall penetrating member 5 of the above-described wall penetrating pipe
The operation of arranging the pipe 4 and the sheath pipe 5 using the pipe 1 will be described. First, a procedure for installing the wall passing tool 51 on the exterior panel 52 will be described.

An installation hole through which the sheath tube guide 54 extends obliquely downward from the inner wall surface side to the outer wall surface side with the end on the side where the wall retainer 55 is fitted as the head. 53 is inserted from the inner wall surface side. This insertion is performed until the flange portion 61 is hooked on the hole edge of the installation hole 53 on the inner wall surface, whereby the sheath tube guide 54 penetrates the installation hole 53 obliquely and has an end portion having the screw portion 62. Protrudes obliquely downward from the outer wall surface of the exterior panel 52. Next, a wall retainer 55 is fitted to the outer periphery of the end portion of the sheath tube guide 54 projecting obliquely downward so that the entire waterproof packing 63 contacts the outer surface of the exterior panel 52.
Finally, a tightening nut 56 as a fixing means is screwed into the screw portion 62 of the sheath tube guide 54, and the screw nut 62 is rotated and tightened to provide a tightening nut 56 over the sheath tube guide 54 and the wall retainer 55. .

By tightening the nut 56, the wall retainer 55 is moved along the axial direction of the sheath tube guide 54 to the outer panel 52.
Press and hold against the outer wall surface of. Thereby, the wall passing tool 51 is installed by obliquely penetrating the exterior panel 52 with the exterior panel 52 sandwiched between the flange portion 61 and the wall retainer 55. Simultaneously with this installation, the water stop packing 63 disposed between the outer surface of the exterior panel 52 and the wall retainer 55 is in a compressed state, so that water can be prevented from entering between the installation hole 53 and the sheath tube guide 54.

In the installation operation, the wall retainer 55 fitted to the end of the sheath tube guide 54 projecting obliquely downward from the outer wall surface of the exterior panel 52 is slidable in the axial direction. Further, the wall retainer 55 is provided with a tightening nut 56.
By moving the wall retainer 55 in the axial direction, the distance between the wall retainer 55 and the flange portion 61 can be adjusted, and the wall passer 51 can be installed. That is, the wall passing tool 51 according to the present embodiment can be easily adapted to installation on various exterior panels 72 having different thicknesses.

Thereafter, the sheath tube guide 54 and the sheath tube through hole 5 of the tightening nut 56 penetrating the exterior panel 52 diagonally.
The sheath tube 5 is passed through the outer wall of the outer panel 52 from the outer wall side of the outer panel 52, for example. By inserting the pipe 4, the pipe 4 is guided and disposed at a predetermined place through the inside of the sheath pipe 5. When water is stopped between the sheath tube guide 54 and the sheath tube 5 in this installation state, the tightening nut 56 is temporarily removed and O
With the ring 64 arranged, the tightening nut 56 is again
Should be tightened. Thereby, the O-ring 64 is elastically deformed as the O-ring 64 is sandwiched between the tightening nut 56 and the end face of the sheath tube guide 54, and the O-ring 64 comes into close contact with the outer peripheral surface of the sheath tube 5, Water stoppage between the pipe guide 54 and the sheath pipe 5 is performed. When water is stopped by caulking, the caulking material may be filled between the sheath tube through hole 56a and the sheath tube 5 without removing the fastening nut 56.

The connection work and the like other than the above points are the same as those in the first embodiment. In addition, the exterior panel 52 of the prefabricated house is preliminarily provided with a wall passing tool 51 at the production stage.
Can be attached and placed, so when supplying to the construction site in this way, there is no need to install the wall passing tool 51 on the exterior panel 52 at the construction site. The arrangement work of the sheath tube 5 and the pipe 4 can be started immediately.

According to the above-described arrangement work of the pipe 4 and the sheath pipe 5 using the wall penetrating tool 51 of the wall penetrating pipe, the sheath pipe guide 54 provided diagonally through the outer panel 52 is used. 5 allows the sheath tube 5 to be disposed indoors along the inner wall surface of the exterior panel 52, and forcibly bends the sheath tube 5 even in the narrow space behind the exterior panel 52 on the indoor side. Does not cause bending deformation. For this reason, the piping 4 that passes through the inside of the sheath tube 5 and is disposed from outside to inside can be easily disposed without forcibly bending and causing buckling deformation. Furthermore, by pulling the pipe 4 obliquely downward from the outdoor side, the pipe 4 can be easily pulled out with a small resistance using the sheath pipe 5 as a guide as in the case of insertion. The work of updating the pipe 4 when it is deteriorated can be easily performed.

In addition, by using the wall passing tool 51,
Since the sheath tube 5 can be continuously arranged from the outdoor to the indoor at the position of the exterior panel 52 without interruption, even if water leaks from the pipe 4 indoors, it is transmitted to the inside of the sheath tube 5 and discharged to the outside. , While the risk of flooding indoors is low,
Since the joint part for the pipe 4 penetrating the exterior panel 52 is on the outdoor side of the exterior panel 52, even if there is water leakage from the joint part which is liable to leak, there is no danger of entering the room.

Further, since the sheath tube guide 54 is provided so as to penetrate the exterior panel 52 so as to be inclined downward toward the outdoor side, rainwater or the like passes through the oblique sheath tube guide 54 from outside. There is almost no risk of entering the room. In addition, an O-ring 6 is provided at the opening on the outdoor side of the sheath tube guide 54.
4 and so on, there is no possibility of further flooding.

Further, the wall passing tool 51 is provided with the sheath tube guide 5.
The outer panel 5 is formed by the flange portion 61 of FIG.
2 is sandwiched from the thickness direction, so that the water stopping process can be easily performed using the water stopping packing 63, and also the plugging process such as the backfilling operation between the installation hole 53 and the wall passing tool 51 can be performed. It can be unnecessary and workability is good. In addition, since the fastening nut 56 for applying a force for sandwiching the exterior panel 52 in the sandwich structure can be advanced and retracted with respect to the exterior panel 52, the wall passing tool 51 must be attached and used according to the thickness change of the exterior panel 52. Can be. In addition, the above-mentioned sandwich structure allows the sheath tube guide 54
When the pipe 4 and the sheath pipe 5 are passed through the sheath pipe guide 54, the operation force applied when the old pipe 4 is replaced with a new pipe, of course,
The pipe or the like can be spread and supported on the flange portion 61 or the wall retainer 55 hooked on the exterior panel 52 on the upstream side in the operation direction of pushing or pulling out the pipe or the like so as to be dispersed and supported by the exterior panel 52. Therefore, there is no danger that the wall pass-through 51 will be accidentally detached from the exterior panel 52, and the junction between the exterior panel 52 and the flange portion 61 and the wall retainer 55 sandwiching the exterior panel 52 will not be loosened. Can be lowered.

Further, by employing the wall passing tool 51 having the above structure, it is not necessary to provide a large circular hole in the exterior panel 52, and the exterior panel
2 can be suppressed from decreasing in strength. In addition, in the fifth embodiment, since the fastening nut 56 is used as the fixing means for adopting the above-mentioned sandwich structure and for tightening the same, the number of fixing parts required for fixing to the exterior panel 52 is reduced, and the tightening operation is also reduced. Since it is easy to move, it is easy to install the wall passing tool 51 on the exterior panel 52. However, as a fixing means in the fifth embodiment, instead of the tightening nut, a lever previously rotatably mounted on the outer surface of the sheath tube guide 54 is operated, so that the cam portion of the lever presses the wall. 55 is moved to the exterior panel 52 side so that the tightening force (exterior panel 5

The same reference numerals as those in the first embodiment denote the same parts, and a description thereof will be omitted. Only different parts will be described.

In the present embodiment, the wall of the house on which the wall passing tool 71 according to the sixth embodiment is installed, and in the case of the present embodiment, the exterior panel (outer wall) 72 of the house made by the prefabricated construction method is inclined at a predetermined position. An installation hole 73 having a circular cross section is formed therethrough. The hole 73 is inclined so as to gradually descend from the indoor side to the outdoor side, and the wall penetration angle θ is 45 °. The wall passer 71 is provided with a sheath tube guide 74.
And a wall retainer 75.

A sheath tube guide 74 made of metal or hard synthetic resin
Is formed integrally with a circumferentially continuous flange portion 74b (see FIG. 13) on the outer periphery of one end of a guide tube portion 74a formed of a cylinder longer than the thickness of the exterior panel 72. The outer diameter of the guide cylinder 74a is substantially equal to the diameter of the installation hole 73. The flange portion 74b is provided so as to protrude outward along a direction intersecting the axis of the guide cylinder portion 74a, and screw holes (not shown) are formed at a plurality of locations. A tapered surface 76 is provided on the inner peripheral surface at one end of the guide cylinder portion 74a to which the flange portion 74b continues. The guide tube portion 74 is formed by the tapered surface 76.
The inner diameter of “a” gradually increases toward the flange portion 74b.

A wall retainer 75 made of metal or hard synthetic resin
Is slidably fitted to the outer periphery of a portion projecting obliquely from the outer surface of the exterior panel 72. The wall retainer 75 only has to be slidable at least in the axial direction of the guide cylinder 74a. For example, at least one concave or convex portion extending in the axial direction is provided on each of the outer peripheral surface of the projecting portion of the sheath tube guide 74 and the inner peripheral surface of the wall retainer 75, and these are provided through the wall passing tool 71.
May be fitted slidably along the axial direction of, and the wall retainer 75 may be prevented from rotating with respect to the guide cylinder 74a.

The wall retainer 75 integrally has a flange portion 75a along the wall surface of the exterior panel 72. The flange portion 75a has a circular shape (see FIG. 14), and is provided so as to protrude outward along a direction intersecting the axis of the wall retainer 75. ing. A waterproof packing 77 having the same shape as the above is bonded to the flange portion 75a. This packing 7
7 is used as a water stopping means between the installation hole 73 and the sheath tube guide 74, but may be adhered to the outer surface of the outer panel 72, or the flange portion 74b and the outer surface of the outer panel 72. They may be provided between them without being bonded to any of them. In addition, this waterproof packing 7
Instead of 7, a caulking process may be performed on the flange portion 75a and the outer surface of the exterior panel 72.

Next, the wall penetrating member 7 for the through-wall pipe having the above-described structure is used.
The operation of arranging the pipe 4 and the sheath pipe 5 using the pipe 1 will be described. First, a procedure for installing the wall passing tool 71 on the exterior panel 72 will be described.

The guide cylinder 7 without the flange 74b
The sheath tube guide 74 is inserted into the installation hole 73 from the indoor side of the exterior panel 72 with the end of 4a at the top. This insertion is performed until the flange portion 74b is hooked on the edge of the installation hole 73 on the inner wall surface of the exterior panel 72, whereby the guide tube portion 74a obliquely faces the exterior panel 72 downward from the indoor side to the outdoor side. Penetrate into. In this state,
The screws 78 that are passed through screw holes (not shown) of the flange portion 74b and screwed into the exterior panel 72 are tightened, respectively.
The sheath tube guide 74 is fixed to the exterior panel 72. Next, the wall retainer 75 is fitted to the end of the sheath tube guide 74 projecting obliquely downward from the outer wall surface of the outer panel 72 so that the entire waterproof packing 77 contacts the outer wall surface of the outer panel 72. Finally, the flange portion 75a of the wall retainer 75
Are screwed into the exterior panel 72 through screw holes (not shown), and the wall retainer 75 is fixed to the exterior panel 72.

By the above procedure, the flange portions 74b, 7
5a, the outer panel 72 is sandwiched between the panels 72.
, And a wall passing tool 71 is installed. Simultaneously with this installation, the watertight packing 77 sandwiched between the outer wall surface of the exterior panel 72 and the wall retainer 75 is in a compressed state, and floods the space between the installation hole 73 and the sheath tube guide 74 from outside. Can be prevented.

In the installation operation, the wall retainer 75 fitted to the end of the sheath tube guide 74 projecting obliquely downward from the outer wall surface of the exterior panel 72 is slidable in the axial direction. Further, since the wall retainer 75 is screwed to the exterior panel 72, even if the thickness of the exterior panel 72 is, for example, either 75 mm or 100 mm, the wall retainer 75 is moved in the axial direction, as described above. A wall passer 71 can be installed. That is, the wall passer 71 according to the present embodiment can be easily adapted to installation on various exterior panels 72 having different thicknesses.

Thereafter, the exterior panel 7 is inserted into the guide tube portion 74a of the sheath tube guide 74 that penetrates the exterior panel 72 at an angle.
2, through the sheath tube 5 from the inner wall side, for example, and penetrate the sheath tube 5 obliquely to the exterior panel 72, and then insert the pipe 4 into the sheath tube 5 from the outer surface side of the exterior panel 72. The pipe 4 is guided to a predetermined place through the inside of the sheath pipe 5 and disposed.

[0129] In this case, a tapered surface 76 is provided at the indoor end of the guide tube portion 74a, so that the entrance when the sheath tube 5 penetrates the wall passing tool 71 from the indoor side is widened. Since the guide tube portion 74a is an oblique straight pipe penetrating the exterior panel 72 without any seam in the middle thereof,
When the sheath tube 5 is inserted into the guide tube 4a (in any direction), there is no possibility that the sheath tube 5 is caught by the guide tube portion 74a, and therefore, the workability of inserting the sheath tube 5 is good. In this installation state, when it is necessary to stop water between the sheath tube guide 74 and the sheath tube 5, a caulking material (not shown) is filled over the end of the guide tube portion 74a protruding outside and the sheath tube 5. What should be done by doing.

The connection work other than the above points is the same as in the first embodiment. In addition, the exterior panel 72 of the prefabricated house is preliminarily provided with a wall passing tool 71 at the production stage.
Can be attached and placed, so when supplying to the construction site in this way, there is no need to install the wall passer 71 on the exterior panel 72 at the construction site, and therefore, The arrangement work of the sheath tube 5 and the pipe 4 can be started immediately.

According to the above-described arrangement work of the pipe 4 and the sheath pipe 5 using the wall penetrating member 71 of the through-the-wall pipe, the sheath pipe guide 74 provided obliquely through the exterior panel 72 is used. 5, the sheath tube 5 can be disposed indoors along the inner wall surface of the exterior panel 72, and the sheath tube 5 is forcibly bent and bent even in the narrow space behind the exterior panel 72 on the indoor side. Does not cause bending deformation. For this reason, the piping 4 that passes through the inside of the sheath tube 5 and is disposed from outside to inside can be easily disposed without forcibly bending and causing buckling deformation. Furthermore, by pulling the pipe 4 obliquely downward from the outdoor side, the pipe 4 can be easily pulled out with a small resistance using the sheath pipe 5 as a guide as in the case of insertion. The work of updating the pipe 4 when it is deteriorated can be easily performed.

In addition, the use of the wall passing tool 71 allows
Since the sheath tube 5 can be continuously arranged from the outdoor to the indoor at the position of the exterior panel 72 without interruption, even if water leaks from the pipe 4 indoors, the water is transmitted to the inside of the sheath tube 5 and discharged to the outside. , While the risk of flooding indoors is low,
Since the joint portion for the pipe 4 penetrating the exterior panel 72 is on the outdoor side of the exterior panel 72, even if there is water leakage from the joint portion that is liable to leak, there is no danger of flooding indoors.

Further, since the sheath tube guide 74 is provided to penetrate the exterior panel 72 so as to be inclined downward toward the outdoor side, rainwater and the like pass through the oblique sheath tube guide 74 from outside. There is almost no risk of entering the room.

Further, the wall passing tool 71 is provided with the sheath tube guide 7.
4 and the flange 75 of the wall retainer 75
a, a sandwich structure sandwiching the exterior panel 72 from the thickness direction is employed, so that the water stopping process can be easily performed by using the water stopping packing 77, and the backfill between the installation hole 73 and the wall passing tool 71 can be achieved. The plugging process such as work can be omitted, and the workability is good. In addition, the above-mentioned sandwich structure allows the piping 4 and the sheath tube 5 to be connected to the sheath tube guide 74 not only when newly passing the piping 4 but also when replacing the deteriorated piping 4 with new piping. The operating force applied when passing through the guide 74 is spread to the flange portion 74b or 75a hooked to the exterior panel 72 on the upstream side in the operation direction of pushing in or pulling out the pipe or the like, and is dispersed by the exterior panel 72. I can support it. Therefore, the wall pass-through 71 does not come off from the exterior panel 72 carelessly, and the joining between the exterior panel 72 and the flange portion 74b or 75a sandwiching the exterior panel 72 is not loosened. Therefore, the risk of impairing waterproofness can be reduced. .

Also, by employing the wall passing tool 71 having the above-described structure, it is not necessary to provide a large circular hole in the exterior panel 72, and the exterior panel 7 provided with the oblique installation hole 73 is not required.
2 can be suppressed from decreasing in strength. Moreover, the wall pass-through 71 according to the sixth embodiment requires only two components, and therefore has a simple structure and can be provided at low cost.
The fixing to the exterior panel 72 can also be easily performed by ordinary screwing work.

(Embodiment 7) Next, with reference to FIGS. 15 to 17, a description will be given of a through-wall member 81 of a through-the-wall pipe according to a seventh embodiment of the present invention. In addition, the wall passing tool 8 described below
15 and 17 are the same as those of the first embodiment except for the portions not shown in FIGS. 15 to 17.
The same reference numerals as those in the first embodiment denote the same parts, and a description thereof will be omitted. Only different parts will be described.

In the present embodiment, the wall of the house on which the wall passer 81 according to the seventh embodiment is installed, and in the case of this embodiment, the exterior panel (outer wall) 82 of the house made by the prefabricated construction method is inclined at a predetermined position. An installation hole 83 having a circular cross section is formed therethrough. The hole 83 is inclined so as to gradually decrease from the indoor side to the outdoor side, and the wall penetration angle θ is 45 °. The wall pass-through 81 includes first and second sheath tube guides 84 and 85, a first hook portion 86, and a plurality of second hook portions 87 to 89.

The first sheath tube guide 84 made of metal or hard synthetic resin forms a circular shape continuously around the one end of a guide tube portion 84a formed of a cylinder shorter than the thickness of the outer panel 82 in the circumferential direction. 16) is formed by integrally providing a flange portion 84b. The outer diameter of the guide tube portion 84a is
3 smaller than the diameter. The flange portion 84b is the guide tube portion 8.
It is provided so as to protrude outward along a direction intersecting the axis of 4a, and threaded holes (not shown) are formed at a plurality of locations.

Similarly, the second sheath tube guide 85 made of a metal or a hard synthetic resin also has a circular shape continuously formed in the circumferential direction on the outer periphery of one end of a guide tube portion 85a formed of a cylinder shorter than the thickness of the outer panel 82. Eggplant (see FIG. 17) is formed by integrally providing a flange portion 85b. The guide tube portion 85a has a larger diameter than the guide tube portion 84a, the outer diameter thereof is substantially equal to the diameter of the installation hole 83, and a tapered surface is provided on the inner peripheral surface at the distal end portion of the guide tube portion 85a. ing. The two guide cylinder portions 84a and 85a are fitted to each other in the installation hole 83. The flange portion 85b is provided so as to protrude outward along a direction intersecting the axis of the guide tube portion 85a, and screw holes (not shown) are formed at a plurality of locations.

The first hook portion 86 is provided with the first sheath tube guide 84.
The second sheath tube guide 85 is provided integrally with the fitting portion of the second sheath tube guide 85, that is, on the inner peripheral surface of the end portion of the guide tube portion 85a in the circumferential direction. I have. The plurality of second hook portions 87 to 89 that can be engaged with and disengaged from the first hook portion 86 are formed by fitting portions of the first sheath tube guide 84 to the second sheath tube guide 85, that is, the outer periphery of the guide tube portion 84a. The surface is provided integrally and continuously in the circumferential direction, for example, by a ridge having a triangular cross section. The second hook portions 87 to 89 are provided at different intervals in the axial direction of the guide tube portion 84a.

The second hook portions 87 to 89 are provided corresponding to the thickness of the exterior panel 82,
When hooked on the hook portion 86, the fitting depth of the two sheath tube guides 84 and 85 is obtained in accordance therewith, and the wall passer 81 can be assembled so as to fit the respective exterior panels 82 having different thicknesses. I have.

That is, several types of prefabricated house exterior panels 82 having different thicknesses are prepared, and any one of them is selected and used. The exterior panel 82 having the maximum thickness (for example, 100 mm) is used. In the application to the panel 82, the first hook portion 86 and the second hook portion 89 are hooked as shown in FIG. 75 mm) for the exterior panel 82, the first hook 86 and the second
By hooking the hook portion 87, the length of the wall pass-through 81 is reduced and adapted, and in the case of applying the intermediate thickness to the exterior panel 82, the first hook portion 86 and the second hook portion 86 are used. The length of the wall passing tool 81 can be adjusted by hooking the connecting portion 87. That is, the wall passer 81 according to the present embodiment can be easily adapted to installation on various exterior panels 82 having different thicknesses.

It is to be noted that such a function of adapting to a plurality of levels of wall thickness is not indispensable, and it is sufficient that at least one of the first and second hook portions is provided, and the first and second hook portions are configured as these hook structures. Instead of the projections as in the present embodiment, one of the projections may be formed as a ridge and the other as a groove having a corresponding shape. However, when the ridges have a triangular cross-section as in the present embodiment, the slopes thereof not only allow the first and second hooking portions to be smoothly engaged and disengaged, but also make the two guide cylinder portions 84a, 85a of the two guide cylinder portions 84a, 85a. This is excellent in that the resistance in fitting can be limited only to the engagement position of the hook portion. In addition,
At the time of these engagement and disengagement, both guide cylinder portions 84a and 85a are accompanied by some elastic deformation.

Next, the wall penetrating member 8 for the through-wall pipe having the above-mentioned structure is used.
The operation of arranging the pipe 4 and the sheath pipe 5 using the pipe 1 will be described. First, the procedure for installing the wall passer 81 on the exterior panel 82 will be described.

The guide cylinder 8 without the flange 84b
The first sheath tube guide 84 is inserted into the installation hole 83 from the indoor side of the exterior panel 82 with the end of 4a at the top. This insertion is performed until the flange portion 84b is placed on the inner wall surface of the exterior panel 82 and hooked on the hole edge of the installation hole 83, whereby the guide tube portion 84a moves the exterior panel 82 from the indoor side to the outdoor side. It is accommodated in the installation hole 83 in an obliquely downward orientation. In this state, the flange portion 84b
Of the first sheath tube guide 8 by tightening the screws 90 which are screwed into the exterior panel 82 through screw holes (not shown).
4 is fixed to the exterior panel 82. In this installation state, the outer peripheral surface of the guide cylindrical portion 84a and the inner peripheral surface of the installation hole 83 are not in contact, and a gap g is provided between them as shown in FIG.

In addition to the configuration of the present embodiment, a spacer step portion having substantially the same diameter as the installation hole 83 is provided continuously or discontinuously in the circumferential direction on the outer periphery of the root portion of the guide cylinder portion 84a on the flange portion 84b side. In the case of implementation, the guide tube portion 84a can be positioned in the radial direction of the installation hole 83 by this step. Therefore, the guide cylinder portion 84a is excellent in that the coaxiality with respect to the installation hole 83 can be easily obtained and the first sheath tube guide 84 of the exterior panel 82 can be fixed, and in fitting with the second sheath tube guide 85 described below. Also both guide tube portions 84
Since it is possible to prevent mutual interference such that the tips of a and 85a are in contact with each other, it is also excellent in that the workability of installing the wall passing tool 81 can be facilitated.

Next, the second sheath tube guide 85 is placed along the inner peripheral surface of the installation hole 83 from the outdoor side of the exterior panel 82 with the end of the guide tube portion 85a without the flange portion 85b at the top. Insert while inserting. This insertion is performed on the flange part 85b.
Is carried out on the outer wall surface of the exterior panel 82 until the edge of the installation hole 83 is caught, whereby the guide cylinder portion 85a is installed in such a manner that the exterior panel 82 becomes obliquely upward from the outdoor side to the indoor side. It is accommodated in the hole 83.

At this time, the guide tube portion 85a is inserted into the gap g between the outer peripheral surface of the guide tube portion 84a and the inner peripheral surface of the installation hole 83, and fitted to the outside of the guide tube portion 84a. At the same time, the first hooking portion 86 provided on the cylindrical portion 85a passes over the second hooking portion, for example, the second hooking portion 89 at a position suitable for the thickness of the exterior panel 82 with a sense of moderation. It is caught (see FIG. 15). The engagement of the hooks 86 and 89 causes the second sheath tube guide 85 to move to the first position.
Since it is connected to the sheath tube guide 84, even if the above-mentioned insertion operation is completed and the hand is released from the second sheath tube guide 85, the guide 85 does not drop obliquely downward.

The two sheath tube guides 84, 8
5 are connected, the screws 91 that are passed through unillustrated screw through holes of the flange portion 85b of the second sheath pipe guide 85 and screwed into the exterior panel 82 are respectively tightened, and the second sheath pipe guide 85 is attached to the exterior panel. Fix to 82. In this case, as described above, the first sheath tube guide 85 is kept in the first position so as not to fall off.
Since the second sheath tube guide 85 is supported by the sheath tube guide 84, the screw 91 can be easily screwed because there is no trouble in performing the work while preventing the second sheath tube guide 85 from falling off with one hand in the tightening operation of the screw 91.

Finally, as shown in FIGS. 15 and 16, a caulking material 92 is provided over the flange portion 85b and the outer wall surface of the outer panel 82 around the flange portion 85b to perform a water stopping process. Thus, it is possible to prevent water from entering between the installation hole 83 and the second sheath pipe guide 85 from outside. Instead of the water stopping process, a water stopping packing may be bonded between the flange portion 85b and the outer surface of the exterior panel 82.

By the above procedure, the flange portions 84b, 8
The outer panel 82 is sandwiched between the outer panels 5a.
Is passed through obliquely, and a wall passing tool 81 is installed.

Thereafter, the first and second sheath tube guides 84 and 85 penetrating obliquely through the exterior panel 82 connected to each other.
Guide tube portions 84 of the wall passer 81 provided with
a and 85a are passed through the sheath tube 5 from, for example, the inner wall surface side of the exterior panel 82, and the sheath tube 5 is obliquely penetrated with respect to the exterior panel 82. Then, piping is performed inside the sheath tube 5 from the outer surface side of the exterior panel 82. By inserting the pipe 4, the pipe 4 is guided and disposed at a predetermined place through the inside of the sheath pipe 5.

In this case, since the guide tube portion 84a of the first sheath tube guide 84 is fitted inside the guide tube portion 85a of the second sheath tube guide 85, the sheath tube 5 is passed from the indoor side to the wall passing tool 81. There is no possibility that the sheath tube 5 penetrating through the guide tube portion 85a is caught on the tip of the guide tube portion 85a. In this installation state, when water is stopped between the sheath tube guide 85 and the sheath tube 5 on the outdoor side, it is sufficient to fill a caulking material (not shown) over these.

The connection work other than the above points is the same as that of the first embodiment. In addition, the exterior panel 82 of the prefabricated house is preliminarily provided with a wall passer 81 at the production stage.
Can be attached and placed, so when supplying to the construction site in this way, there is no need to install the wall passing tool 81 on the exterior panel 82 at the construction site, and therefore, The arrangement work of the sheath tube 5 and the pipe 4 can be started immediately.

According to the work of disposing the pipe 4 and the sheath tube 5 using the wall penetrating member 81 of the wall penetrating pipe described above, the sheath tube is attached to the wall penetrating member 81 provided obliquely through the exterior panel 82. 5, the sheath tube 5 can be disposed indoors along the inner wall surface of the exterior panel 82, and the sheath tube 5 is forcibly bent even in the narrow space behind the exterior panel 82 on the indoor side. Does not cause bending deformation. For this reason, the piping 4 that passes through the inside of the sheath tube 5 and is disposed from outside to inside can be easily disposed without forcibly bending and causing buckling deformation. Furthermore, by pulling the pipe 4 obliquely downward from the outdoor side, the pipe 4 can be easily pulled out with a small resistance using the sheath pipe 5 as a guide as in the case of insertion. The work of updating the pipe 4 when it is deteriorated can be easily performed.

In addition, the use of the wall passing tool 81 allows
Since the sheath tube 5 can be continuously arranged from the outdoor to the indoor at the position of the exterior panel 82 without interruption, even if water leaks from the pipe 4 indoors, it is transmitted to the inside of the sheath tube 5 and discharged to the outside. , While the risk of flooding indoors is low,
Since the joint part for the pipe 4 penetrating the exterior panel 82 is on the outdoor side of the exterior panel 82, even if there is water leakage from the joint part that is liable to leak, there is no danger of flooding indoors.

The second sheath pipe guide 85 on the outdoor side is inclined so as to descend obliquely toward the outdoor side, and the exterior panel 82 is screwed.
There is almost no danger of intrusion from outside to inside through the guide tube portions 84a, 85a inside.

Further, the wall pass-through 81 is formed by the flange portions 84b, 85b of the first and second sheath tube guides 84, 85.
Since the sandwich panel has a sandwich structure in which the exterior panel 82 is sandwiched from the thickness direction, plugging processing such as backfilling work between the installation hole 83 and the guide cylinders 84a, 85a of the wall passing tool 81 can be omitted, and the workability is improved. Good. In addition, the above-mentioned sandwich structure allows newly added piping 4 to the sheath tube guides 84 and 85.
When the old pipe 4 is replaced with a new pipe as well as when the old pipe 4 is replaced, the operating force applied when the pipe 4 or the sheath pipe 5 is passed through the wall passing tool 81 is pushed into the pipe 4 or the like. Flange portion 84b or 8 hooked on exterior panel 82 on the upstream side in the operation direction of pulling out or pulling out
5b and can be dispersed and supported by the exterior panel 82. Therefore, the wall pass-through 81 does not come off from the exterior panel 82 carelessly, and the junction between the exterior panel 82 and the flange portion 84b or 85b sandwiching the exterior panel 82 is not loosened, so that the risk of impairing waterproofness can be reduced. .

Also, by employing the wall passing tool 81 having the above-described structure, it is not necessary to provide a large circular hole in the exterior panel 82, and the exterior panel 8 provided with the oblique installation hole 83 is not required.
2 can be suppressed from decreasing in strength. Moreover, since the wall pass-through 81 according to the seventh embodiment requires only two components, it has a simple structure and can be provided at a low cost. Can be performed more easily. In the seventh embodiment, the means for fixing the flange portions 84b, 85b to the exterior panel 82 may be an adhesive means such as an adhesive or a double-sided adhesive tape, instead of screwing. ,
The first hooking portion 86 and the second hooking portions 87 to 89 have a large connection strength due to the hooking, so that both flange portions 8 are formed.
When 4b and 85b are pressed against the inner and outer wall surfaces of the outer panel 82, respectively, the fixing means may be omitted.

(Embodiment 8) Next, with reference to FIG. 18, a wall penetrating device 1 for a through-wall pipe according to a seventh embodiment of the present invention.
01 will be described. Except for the wall passing tool 101 and the installation hole 103 in the wall, which are the same as those of the first embodiment, including the parts not shown in FIG. In the description, the same reference numerals as in the first embodiment denote the same parts, and a description thereof will be omitted. Only different parts will be described.

[0161] The wall passer 101 according to the eighth embodiment.
Is installed at a predetermined position of a wall of the house where the is installed, in the case of the present embodiment, an exterior panel (outer wall) 102 of the house made by the prefabricated construction method. The hole 103 is inclined so as to gradually decrease from the indoor side to the outdoor side, and the wall penetration angle θ is 45 °. The wall passing tool 101 is formed of a single component integrally formed of a metal or a hard synthetic resin, and includes a sheath tube guide 104 and a flange portion 105.
And

More specifically, the sheath tube guide 104 is formed of a cylinder having a thickness smaller than the thickness of the outer panel 102, and is integrally provided with a circular flange portion 105 which is continuously formed in the circumferential direction on the outer periphery of one end. The outer diameter of the sheath tube guide 104 is the installation hole 1
03 is substantially equal to the diameter of the hole, and a tapered surface 10 is formed on the inner peripheral surface of the end of the sheath tube guide 104 where the flange portion 105 is not provided.
4a is provided. The flange portion 105 is provided so as to protrude outward along a direction intersecting the axis of the sheath tube guide 104, and screw holes (not shown) are formed at a plurality of locations.

Next, the wall penetrating member 1 of the above-described wall penetrating pipe
The operation of arranging the pipe 4 and the sheath pipe 5 using 01 will be described.
First, a procedure for installing the wall passing tool 101 on the exterior panel 102 will be described.

The sheath tube guide 1 having the tapered surface 104a
The wall passer 101 is inserted into the installation hole 103 from the outdoor side of the exterior panel 102 with the end of 04 being the top. This insertion is performed until the flange portion 105 is placed on the outer wall surface of the exterior panel 102 and is hooked on the hole edge of the installation hole 103, so that the sheath tube guide 104 moves the exterior panel 102 from the outdoor side to the indoor side. It is accommodated in the installation hole 103 in an obliquely upward orientation. In this state, the outer panel 1 is passed through a threaded hole (not shown) of the flange 105.
Then, the screws 106 screwed into the 02 are fastened to fix the wall passing tool 101 to the exterior panel 102. Finally, a caulking material 107 is provided over the flange portion 105 and the outer wall surface of the outer panel 102 around the flange portion 105 to perform a water stopping process. Thus, it is possible to prevent water from entering between the installation hole 103 and the wall passing tool 101 from outside. Instead of the water stopping process, a water stopping packing can be bonded between the flange portion 105 and the outer surface of the exterior panel 102.

According to the above procedure, the wall passing tool 101 is installed obliquely through the exterior panel 102.

Thereafter, the sheath tube 5 is passed through the sheath tube guide 104 from, for example, the inner wall surface side of the exterior panel 102, and the sheath tube 5 is obliquely penetrated with respect to the exterior panel 102.
By inserting the pipe 4 into the sheath pipe 5 from the outer surface side of the exterior panel 102, the pipe 4 is guided and disposed at a predetermined location through the sheath pipe 5.

In this case, since the tapered surface 104 a is provided at the tip of the sheath tube guide 104, the sheath tube 5 penetrating the sheath tube 5 through the wall guide 101 from the indoor side is connected to the tip of the sheath tube guide 104. Therefore, the sheath tube 5 can be easily inserted. In this installation state, when water is stopped between the wall passing tool 101 and the sheath tube 5 on the outdoor side, it may be performed by filling a caulking material (not shown) over these.
