JP-A-9-105482 (FIG. 3)

  Since the above-mentioned conventional technology penetrates the pipe diagonally with respect to the wall, it is excellent in that the load on the pipe is small when the pipe runs along the inner and outer surfaces of the wall and that the pipe can be inserted and removed from the outdoor side for renewal. ing.

  However, since the oblique water-stopping member projecting to the outdoor side with respect to the wall is not connected to another sheath pipe, the sheath pipe or the pipe is passed through the water-stopping member and the sheath pipe. There is a problem that the tip of the pipe hits the end of the water stop member and it is difficult to pass the pipe, and the sheath pipe is easily pushed by the pipe when passing the pipe from the outdoor side, so that the workability through the pipe is not good.

The problem to be solved by the present invention is that the sheath pipe can be penetrated through the wall without being forced to be bent and arranged along the wall, and the pipe that is passed through the sheath pipe can be arranged without being bent excessively. , moreover, it is to obtain a through-wall structure and the wall through instrument through-wall pipe wall through the pipe that can correspond to the change in thickness of the wall.

The wall through tool of the wall through pipe according to the invention of claim 1 is a sheath pipe guide inserted into an installation hole that obliquely penetrates the wall, has a cylindrical shape longer than the thickness of the wall, and has one end at the one end. A sheath tube that has a flange portion that hooks on one surface of the wall, and has a threaded portion on the outer periphery of the other end that is disposed so as to project obliquely from the other surface of the wall, and penetrates the wall without interruption. A ring-shaped wall retainer that is provided to be fitted to the outer periphery of the other end portion of the sheath tube guide so as to be slidable at least in the axial direction, and along the other surface of the wall. A wall retainer sandwiching the wall between the flange portion and the flange portion, and a sheath tube passage hole at the center, covering the end surface of the sheath tube guide on the side where the screw portion is provided A tightening nut that is screwed into the threaded portion to hold the wall retainer pressed against the wall; Is sandwiched between the end face of the clamping nut the sheath tube guide, the tightening of the tightening nut is obtained by including an O-ring which is in close contact with the outer peripheral surface of the sheath tube is elastically deformed, the.

In order to install the wall through tool of the wall through pipe according to the first aspect of the present invention on the wall, first, a wall presser is fitted from one side or the other side of the wall with respect to the installation hole obliquely penetrating the wall. The guide is penetrated obliquely with respect to the wall by inserting the sheath tube guide with the end of the mating side as the head until the flange portion abuts against the wall. Next, a wall presser is fitted to the outer periphery of the end portion of the sheath guide that protrudes obliquely from the wall. Finally, the wall retainer is moved to the wall side along the axial direction of the sheath tube guide and pressed against the wall by screwing a tightening nut into the threaded portion of the end portion of the sheath tube guide and tightening operation. Hold it in the state. Accordingly, the wall threading tool can be installed obliquely with respect to the wall in a state where the wall is sandwiched between the flange portion and the wall press. In this case, since the tightening nut that gives the force to pinch the wall can advance and retreat with respect to the wall, the wall threading tool can be installed in accordance with the change in the wall thickness.

Therefore, after this, after passing through the sheath tube from the one surface side or the other surface side with respect to the sheath tube guide that obliquely penetrates the wall, the sheath tube is obliquely penetrated with respect to the wall, and then the pipe is installed in the sheath tube. By inserting the pipe, the pipe can be guided to a predetermined place through the inside of the sheath pipe. Thus, in the wall threader of the wall through pipe according to the first aspect of the present invention, since the cylindrical sheath tube guide that penetrates the oblique installation hole provided in the wall is provided, the sheath tube is passed through this guide. Thus, the sheath tube can be disposed along the wall so as to penetrate obliquely through the wall without being bent excessively. Therefore, for example, a sheath pipe can be arranged without difficulty in a narrow wall space behind the outer wall, and a pipe guided through the inside of the sheath pipe can be arranged indoors without being bent excessively. And, by tightening the tightening nut, the O-ring disposed between the end surface of the sheath tube guide covered with the nut is elastically deformed and closely contacts the outer peripheral surface of the sheath tube. Water can be stopped between.

  Further, in the first aspect of the present invention, as in the second aspect of the present invention, the recesses or recesses that extend in the axial direction on the outer peripheral surface of the sheath tube guide and the inner peripheral surface of the wall presser are fitted to each other. It is preferable to provide a convex portion to prevent the wall presser from rotating with respect to the sheath tube guide. According to the second aspect of the invention, there is an advantage that the workability can be improved by preventing the wall presser from rotating in accordance with the fixing operation by the tightening nut.

The wall through structure of the wall through pipe according to the invention of claim 3 uses the wall threading tool according to claim 1 or 2 and the sheath pipe guide is inclined with respect to the wall. At least a part of the guide is disposed in an installation hole that obliquely penetrates the wall, and the sheath tube is passed through the oblique sheath tube guide in an inclined direction through the sheath tube in an inclined direction without being interrupted with respect to the wall. At the same time, it is guided through a pipe penetrating the wall into the oblique sheath pipe, and the pipe is arranged without bending.

The invention according to claim 3 uses the wall threader according to claim 1 or 2 to pass the sheath tube through a cylindrical sheath tube guide in which an oblique installation hole provided in the wall is arranged. The tube can be disposed along the wall obliquely penetrating the wall without forcibly bending. Therefore, for example, a sheath pipe can be arranged without difficulty in a narrow wall space behind the outer wall, and a pipe guided through the inside of the sheath pipe can be arranged indoors without being bent excessively. Since the pipe can be arranged in this way, when this pipe is a liquid feeding pipe and a liquid leak occurs from the pipe, the leaked liquid can be led out to the outside or the like through a sheath pipe obliquely penetrating the wall.

The wall through structure of the wall through pipe according to the invention of claim 4 is provided with the inclined installation hole inclined so as to be lowered toward the outdoor side of the wall separating the outdoor and the indoor, and the wall threading tool The wall retainer and the clamping nut are arranged on the outdoor side.

By passing the sheath tube through the sheath tube guide, this sheath tube is penetrated obliquely with respect to the wall, and the sheath tube through which the pipe is passed is arranged along the wall without forcibly bending it. Therefore, for example, it is advantageous to dispose a sheath tube or the like inside a narrow wall space, and a pipe passing through the sheath tube can be disposed without being bent excessively. In addition, since the tightening nut that gives the force to pinch the wall can advance and retreat with respect to the wall, a wall threading tool can be installed in response to a change in the thickness of the wall. Furthermore, since the liquid leaking from the pipe can be led out by the sheath pipe, it is possible to prevent water from entering the room.

According to the wall through structure of the wall through pipe according to the invention of claim 4 , there is an advantage that rainwater does not easily enter through the sheath pipe guide that obliquely penetrates the wall partitioning the outdoor and the indoor.

According to the wall through structure of the wall through pipe according to the invention of claim 5, there is an advantage that water can be stopped between the installation hole and the sheath pipe guide .

Hereinafter, with reference to FIGS. 1-4, the wall threading tool of the wall penetration piping which concerns on the reference example of this invention is demonstrated.

FIG. 1 is a cross-sectional view showing a state in which a wall threading tool 1 of a wall through pipe of a reference example is attached to an installation hole 3 of an outer wall 2 of a detached building and a pipe 4 and a sheath pipe 5 are penetrated.

  As shown in FIGS. 2A and 2B, the wall threading tool 1 includes a first wall threading member 6, a second wall threading member 7, and a connecting means.

  The first wall-passing member 6 made of synthetic resin is opened from the outdoor side to the installation holes 3 that are open on both sides in the thickness direction of the outer wall 2 as a house wall and are formed in a long oval shape in the vertical direction. A first tube portion 8 to be fitted, a first flange portion 10 that is formed integrally with the first tube portion 8 and projects outward, and engages with an outdoor side edge of the installation hole 3; For example, a closed portion 12 that is integrally formed on the outdoor side end portion and closes the inside of the first cylindrical portion 8, and a cylindrical shape that is integrally formed at the lower portion of the closed portion 12 and that obliquely penetrates from the indoor side to the outdoor side. And a formed sheath guide 13. The installation hole 3 penetrates the outer wall 2 along a direction orthogonal to the outer wall 2.

  The sheath tube guide 13 is provided obliquely so that the indoor side end thereof is located above the outdoor side end, and thus protrudes obliquely downward from one end of the closed portion 12. Furthermore, the sheath tube guide 13 has a slightly larger diameter than the sheath tube 5 so that the sheath tube 5 described later can be inserted. In the use state, the indoor side end of the sheath guide 13 is positioned in the installation hole 3 as shown in FIG.

  When the first wall threading member 6 is installed in the installation hole 3 on the outer wall 2 side of the first flange portion 10 that is continuous in the circumferential direction and is flush with the closing portion 12, for example, A water stop packing 14a is provided to prevent the rainwater or the like from entering the installation hole 3 by being filled with a gap with the outer wall 2. In addition, when the said clearance gap is caulk-processed, the water stop packing 14a is omissible.

  The closing portion 12 has a screw through hole 16 for screwing a screw 15 as a connecting means for connecting the first wall passing member 6 and a second wall passing member 7 to be described later on the inside of the first tube portion 8. It is provided to penetrate through.

  The second wall-passing member 7 made of synthetic resin is formed integrally with the second cylindrical portion 17 fitted into the installation hole 3 provided in the outer wall 2 from the indoor side, and projects outward from the second cylindrical portion 17. The second flange portion 19 catches the indoor side edge portion of the installation hole 3. On the outer wall 2 side of the second flange portion 19 that is continuous in the circumferential direction, when the second wall passing member 7 is installed in the installation hole 3, the gap between the second flange portion 19 and the outer wall 2 is filled and sandwiched. A water packing 14b is provided. This water blocking packing 14b may be omitted. Further, on the inner side of the outdoor side end portion of the second cylindrical portion 17, a screwing portion 21 having a screw hole for receiving the screw 15 as a connecting means is opposed to the screw hole 16 of the first wall passing member 6. It is provided in the position to do.

  When the wall threading tool 1 is attached by being fitted into the installation hole 3 or the like, the width D of the first tube portion 8 and the second tube portion 17 along the vertical direction of the house is the outer diameter d of the sheath tube 5. The size is about 2 to 3 times or more. Thus, the width D of the first cylinder portion 8 and the second cylinder portion 17 is formed sufficiently larger than the outer diameter d of the sheath tube 5.

  As a specific example of the dimensions of the wall threading tool 1, when the pipe 4 having a nominal diameter of 13 mm is passed through the sheath pipe 5 having a nominal diameter of 28 mm and penetrated through the outer wall 2 having a thickness of 75 mm, the outer wall 2 The sheath pipe guide 13 is provided with respect to the closing portion 12 so that the insertion angle of the pipe 4 and the sheath pipe 5 passing through the outer wall 2 with respect to the pipe 4 is 45 °. At this time, the longest diameter of the installation hole 3 is preferably 150 mm or more. Further, as shown in FIG. 3, the sheath tube guide 13 only needs to have an opening in a direction in which the sheath tube 5 contacts when penetrating, and the opening may be elliptical when viewed from the front. In this case, the wall space 24 necessary for the arrangement is set to have a width of 70 mm or more.

  Next, an operation of attaching the wall threading tool 1 of the wall through pipe to the outer wall 2 will be described.

  The outer wall 2 has an installation hole 3 that is adjusted to the size of the first and second cylindrical portions 8 and 17 in advance and communicates between the outdoor side and the indoor side along a direction orthogonal to the outer wall 2. Open. First, the first wall passing member 6 is attached. The first tubular portion 8 of the first wall passing member 6 is fitted from the outdoor side of the installation hole 3 toward the indoor side until the first flange portion 10 is hooked on the outdoor side edge of the installation hole 3 and stops. At this time, the gap between the first flange portion 10 and the outdoor side of the outer wall 2 is closed without a gap by the water stop packing 14 a provided on the wall side of the first flange portion 10.

  Next, the second wall passing member 7 is attached. Contrary to the first wall passing member 6, the second flange portion 19 is located on the indoor side edge of the installation hole 3, with the second cylindrical portion 17 of the second wall passing member 7 directed from the indoor side to the outdoor side of the installation hole 3. Fit it until it stops and stops. Thereby, the indoor side end of the first cylinder part 8 and the outdoor side end part of the second cylinder part 17 approach in the installation hole 3. At this time, as in the case of the first wall passing member 6 described above, the gap between the second flange portion 19 and the indoor side of the outer wall 2 is caused by the water stop packing 14b provided on the wall side of the second flange portion 19. It is closed without a gap.

  Thereafter, the screw 15 is screwed from the outdoor side into the screwing portion 21 of the second wall passing member 7 through the screw through hole 16 of the closing portion 12 of the first wall passing member 6, thereby the first wall passing member 6 and the first wall passing member 6 are connected to the first wall passing member 6. The two-wall through member 7 is connected, and the water-stopping packings 14a and 14b are pressed against the inner and outer wall surfaces of the outer wall 2, respectively. Thus, the attachment of the wall threading tool 1 of the wall through pipe to the installation hole 3 of the outer wall 2 is completed.

Since the wall threading tool 1 of the wall through pipe of this reference example is simply connecting the first wall threading member 6 and the second wall threading member 7 with screws 15, the wall threading tool 1 of this wall through pipe will be removed in the future. When the need arises, the wall threading tool 1 of this wall through pipe can be removed from the installation hole 3 of the outer wall 2 simply by loosening and removing the screw 15.

  Next, for example, an arrangement operation is performed in which the liquid supply pipe 4 and the sheath pipe 5 for hot water supply or water supply are passed through the wall through tool 1 of the wall through pipe attached to the installation hole 3 of the outer wall 2 as described above. explain. The pipe 4 is a cross-linked polyethylene pipe and has flexibility, and the sheath pipe 5 through which the pipe 4 passes is made of a synthetic resin harder than the pipe 4, but a corrugated pipe having excellent flexibility is used. It has been adopted.

  The sheath tube 5 is passed from the outside to the inside, for example. That is, one end of the sheath tube 5 is passed obliquely upward from the outdoor side through the sheath tube guide 13 of the first wall passing member 6. As shown in FIGS. 3 and 4 (a) and 4 (b), the sheath tube guide 13 obliquely penetrates the closed portion 12 so that the indoor side end portion is located above the outdoor side end portion. Therefore, the sheath tube 5 passed from the outside to the inside through the sheath guide 13 passes through the wall threading tool 1 obliquely upward without being caught by the second wall threading member 16, and the outer wall 2 is closed. Since it is pushed upward along the inner wall surface, as shown in FIG. 1, a narrow wall space 24 formed by the outer wall 2 and the interior board 23 of the room, or an attic space above the ceiling 25 of the room. 26 can be arranged without being bent by force and causing buckling deformation. The sheath tube 5 that has been disposed is fixed so as not to fall off using a U-shaped saddle 27 or the like attached to the outer wall 2 or the like at an appropriate interval.

  Next, the pipe 4 is inserted into the sheath pipe 5 diagonally upward from the outside with respect to the sheath pipe 5 that is obliquely penetrated through the wall threading tool 1 and is supported by the sheath pipe guide 13 at an intermediate portion. 5 along the line. Since the sheath pipe 5 is disposed to a predetermined position that is already necessary without being bent excessively, the pipe 4 passes through the inside of the sheath pipe 5 without being bent and causing buckling deformation. Guided to a predetermined position. After the sheath tube 5 is disposed and fixed, as shown in FIG. 3, a water-stopping treatment with a caulking material 28 is applied to the opening on the outdoor side of the sheath guide 13 so that the sheath tube 5 and the opening are separated. Close the gap. By this water stop treatment, the risk of rainwater or the like entering from the outside to the inside through the sheath guide 13 can be extremely reduced. In place of the caulking process, an O-ring may be sandwiched between the sheath tube guide 13 and the sheath tube 5, or both water stop treatments may be used together.

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

  As described above, according to the arrangement work of the pipe 4 and the sheath pipe 5 using the wall through tool 1 of the wall penetration pipe described above, the sheath pipe 5 is passed through the sheath pipe guide 13 provided obliquely with respect to the outer wall 2. Thus, the sheath tube 5 is disposed indoors along the wall surface of the outer wall 2. Since the width D along the vertical direction of the first tube portion 8 and the second tube 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. A sufficiently wide space S that does not occur can be secured in the first tube portion 8 and the second tube portion 17. Further, the sheath tube 5 can be placed indoors along the wall surface of the outer wall 2 by passing the sheath tube 5 through the sheath tube guide 13 provided obliquely with respect to the outer wall 2.

  Therefore, even in the narrow wall space on the indoor side of the outer wall 2, the sheath tube 5 is not forcibly bent to cause buckling deformation. For this reason, the pipe 4 that passes through the inside of the sheath pipe 5 and is arranged from the outside to the inside can be easily arranged without forcibly bending and causing buckling deformation. Further, by pulling the pipe 4 obliquely downward from the outdoor side, the pipe 4 can be easily pulled out with little 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 aged can be easily performed.

  Further, the sheath tube 5 is continuously arranged from the outside to the indoor without interruption at the position of the wall threading tool 1 of the wall through pipe. For this reason, even if water leaks out from the pipe 4 indoors, the water travels through the inside of the sheath pipe 5 and is discharged to the outside. And since the sheath pipe 5 and the piping 4 have penetrated the outer wall 2, and the joint part with respect to the pipe 4 exists in the outdoor side of the outer wall 2, even if there is a leak from the joint part which is easy to leak, there is a possibility of flooding indoors There is no.

  Further, since the sheath guide 13 is provided obliquely through the closed portion 12 so that the indoor side is located above the outdoor side, rainwater or the like passes through the sheath guide 13 obliquely downward from the outside. There is almost no risk of entering indoors. In addition, since the opening on the outdoor side of the sheath tube guide 13 is subjected to water-stopping treatment with the caulking material 28 or the like to close the gap between the sheath tube 5 and the opening, there is no further possibility of flooding.

  In addition, since the first and second flange portions 10 and 19 and the water-stopping packings 14a and 14b provided on the flange portions 10 and 19 respectively have a sandwich structure in which the installation holes 3 are sandwiched from both sides of the outer wall 2 without gaps, Water treatment can be performed, and plugging processing such as backfilling work between the installation hole 3 and the wall threading tool 1 can be made unnecessary, and workability is good.

  Further, the order of the work of attaching the wall threading tool 1 to the installation hole 3 and the work of arranging the pipe 4 and the sheath pipe 5 indoors may be first. In the case of a prefabricated house, the wall threading tool 1 can be attached to the outer wall 2 in advance. In this case, the wall threading tool 1 is not required to be installed at the construction site. It can be carried out.

  Further, since the shape of the wall threading tool 1 as viewed from the front is an oval shape that is long in the vertical direction and is small, the installation hole 3 provided in the outer wall 2 also has the same oval shape as viewed from the front. Therefore, it is not necessary to provide a large circular hole in the outer wall 2, and a decrease in strength of the outer wall 2 due to the installation hole 3 can be suppressed.

Next, with reference to FIG. 5 , the wall threading tool 51 of the wall penetration piping which concerns on one embodiment of this invention is demonstrated. In addition, since it is the same as that of the said embodiment including the part which is not shown in FIG. 5 except the wall threading tool 51 and the wall installation hole 53 which are demonstrated below, description about the same parts, such as a sheath pipe and piping, The same reference numerals as those in the embodiment are attached and the description thereof is omitted, and only different portions will be described.

Wall of housing wall through device 51 according to this exemplary embodiment is installed at a predetermined position of the housing of the outer panel (outer wall) 52 which is made by the prefabricated in the case of this embodiment, a cross section through the obliquely A circular installation hole 53 is opened. The hole 53 is inclined so as to gradually fall from the indoor side to the outdoor side. The wall threading tool 51 includes a sheath tube guide 54, a wall press 55, and a tightening nut 56 as a fixing means.

  The sheath tube guide 54 made of metal or hard synthetic resin has a cylindrical shape longer than the thickness of the exterior panel 52, and a flange portion 61 continuous in the circumferential direction is provided on the outer periphery of one end portion, and the outer periphery of the other end portion is provided. Is provided with a screw portion 62. The flange portion 61 is provided so as to protrude outward along the direction intersecting the axis of the sheath tube guide 54. The sheath tube guide 54 is provided obliquely, for example, from the inside of the exterior panel 52 through the installation hole 53 with the end provided with the threaded portion 62 as a head, whereby the flange portion 61 is provided. The inner surface of the mounting hole 53, specifically, the hole edge on the indoor side of the installation hole 53 is hooked.

  The wall presser 55 made of metal or hard synthetic resin is slidably fitted to the outer periphery of the portion protruding obliquely from the outer surface of the exterior panel 52. The wall retainer 55 only needs to be slidable at least in the axial direction of the sheath tube guide 54. For example, one or more recesses or projections extending in the axial direction are provided on the outer peripheral surface of the sheath tube guide 54 and the inner peripheral surface of the wall presser 55, respectively, and these are extended along each other, that is, in the axial direction. The wall presser 55 may be slidably fitted to prevent the wall presser 55 from rotating with respect to the sheath guide 54. In this case, the wall presser 55 is rotated with a fixing operation described later. It is excellent in that it can prevent and improve workability.

  The wall retainer 55 has an oblique wall retainer surface 55 a along the wall surface of the exterior panel 52. The surface 55a has a ring shape when viewed from the front, and a water-stop packing 63 of the same shape is bonded thereto. This packing 63 is used as a water stop means between the installation hole 53 and the sheath tube guide 54, but may be bonded to the outer surface of the exterior panel 52 instead of the above example, You may pinch | interpose between these, without adhering to either of the surface 55a and the outer surface of the exterior panel 52. FIG. Instead of the water stop packing 63, a caulking material may be applied to the wall pressing surface 55a and the outer surface of the exterior panel 52 for coking.

  The clamping nut 56 made of metal or hard synthetic resin has a sheath tube passage hole 56a at the center, and is screwed into the threaded portion 62 so as to be removable. The peripheral end surface of the nut 56 is in contact with the end surface of the wall press 55 opposite to the surface 55a. Therefore, the tightening nut 56 is provided over the sheath tube guide 54 and the wall presser 55, and by tightening the nut 56, the wall presser 55 can be moved toward the outer surface of the exterior panel 52 and can be pressed and held. It has become.

In FIG. 5 , reference numeral 64 denotes an O-ring provided between the end face of the sheath tube guide 54 on the side where the threaded portion 62 is provided and the tightening nut 56, and is elastically deformed by tightening the tightening nut 56. It is in close contact with the outer peripheral surface of the sheath tube 5 and is used to stop water at the sheath tube passage hole 56a .

In addition, as an example of a specific dimension of the wall through-hole 51 of the wall through pipe having the above-described configuration, the pipe 4 having a nominal diameter of 13 mm is obliquely penetrated through the outer panel 52 having a thickness of 75 mm together with the sheath pipe 5 having a nominal diameter of 28 mm. In order to reduce the strength reduction of the exterior panel 52 due to the installation hole 53, it is desirable that the wall penetration angle θ of the installation hole 53 is 45 ° and the diameter of the installation hole 53 is about 45 mm. The configuration other than the points described above is the same as that of the reference example .

  Next, the arrangement | positioning operation | work of the piping 4 and the sheath tube 5 using the wall through tool 51 of the wall penetration piping of the said structure is demonstrated. First, the procedure for installing the wall threading tool 51 on the exterior panel 52 will be described.

  The casing tube guide 54 is inserted into the installation hole 53 penetrating through the exterior panel 52 from the inner wall surface side toward the outer wall surface side with the end portion on the side where the wall presser 55 is fitted as the head. Insert from the inner wall side. This insertion is performed until the flange portion 61 is caught on the hole edge of the installation hole 53 on the inner wall surface, whereby the sheath tube guide 54 obliquely penetrates the installation hole 53 and has the threaded portion 62. However, it projects obliquely downward from the outer wall surface of the exterior panel 52. Next, a wall presser 55 is fitted to the outer periphery of the end portion of the sheath guide 54 that protrudes obliquely downward so that the entire waterproofing packing 63 contacts the outer surface of the exterior panel 52. Finally, a tightening nut 56 as a fixing means is screwed into the threaded portion 62 of the sheath tube guide 54, and is rotated and tightened to provide the tightening nut 56 over the sheath tube guide 54 and the wall presser 55. .

  By tightening the nut 56, the wall presser 55 is pressed and held against the outer wall surface of the exterior panel 52 along the axial direction of the sheath guide 54. Accordingly, the wall threading tool 51 is installed through the exterior panel 52 obliquely with the exterior panel 52 sandwiched between the flange portion 61 and the wall presser 55. Simultaneously with this installation, the water-stop packing 63 disposed between the outer surface of the exterior panel 52 and the wall presser 55 is in a compressed state, and water intrusion between the installation hole 53 and the sheath guide 54 can be prevented.

In the installation operation, the wall retainer 55 fitted to the end of the sheath tube guide 54 protruding obliquely downward from the outer wall surface of the exterior panel 52 is slidable in the axial direction, and the wall Since the presser 55 is moved to the exterior panel 52 by tightening the tightening nut 56, the wall passer 51 can be installed by adjusting the distance between the wall presser 55 and the flange portion 61 by the axial movement of the wall presser 55. . That is, the wall threading tool 51 according to the present embodiment can be easily adapted to be installed on various exterior panels 72 having different thicknesses.

Thereafter, the sheath tube 5 is passed through the sheath tube guide 54 and the sheath tube passage hole 56a of the tightening nut 56 obliquely through the sheath panel 52, for example, from the outer wall surface side of the sheath panel 52, and the intermediate portion of the sheath tube 5 is sheathed. After passing through the panel 52 obliquely, the pipe 4 is inserted into the sheath pipe 5 from the outer wall surface side of the exterior panel 52, thereby leading the pipe 4 to a predetermined place through the sheath pipe 5. To do. In this installed state, when water is shut off between the sheath tube guide 54 and the sheath tube 5, the tightening nut 56 is once again in a state in which the tightening nut 56 is once removed and the O-ring 64 is disposed inside thereof. Can be tightened. As a result, the O-ring 64 is elastically deformed as it is sandwiched between the tightening nut 56 and the end surface 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 tube guide 54 and the sheath tube 5 is performed.

The connection work other than the above points is the same as the reference example . In addition, since the wall threading tool 51 can be mounted and placed in advance on the exterior panel 52 of the prefabricated house in the production stage, the wall threading tool is used at the construction site when supplying it to the construction site in this way. The operation of installing 51 on the exterior panel 52 is no longer required, and therefore, the disposing operation of the sheath pipe 5 and the pipe 4 at the construction site can be started promptly.

  According to the operation of arranging the pipe 4 and the sheath pipe 5 using the wall threading tool 51 of the wall through pipe described above, the sheath pipe 5 is passed through the sheath pipe guide 54 provided obliquely through the exterior panel 52. Thus, the sheath tube 5 can be disposed indoors along the inner wall surface of the exterior panel 52, and the sheath tube 5 is forcibly bent even in the narrow wall space on the indoor side of the exterior panel 52 to cause buckling deformation. There is no waking. For this reason, the pipe 4 that passes through the inside of the sheath pipe 5 and is arranged from the outside to the inside can be easily arranged without forcibly bending and causing buckling deformation. Further, by pulling the pipe 4 obliquely downward from the outdoor side, the pipe 4 can be easily pulled out with little 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 aged can be easily performed.

  Moreover, since the sheath tube 5 can be continuously arranged from the outdoor to the indoor without being interrupted at the position of the exterior panel 52 by employing the wall threading tool 51, the sheath tube can be used even if water leaks from the piping 4 indoors. 5, which is discharged to the outside through the inside of the interior 5 and has a low risk of flooding indoors, and since the joint portion for the pipe 4 penetrating the exterior panel 52 is on the exterior side of the exterior panel 52, the joint portion easily leaks. There is no risk of intrusion even if water leaks from

  Moreover, since the sheath tube guide 54 is provided so as to be inclined obliquely downward toward the outdoor side and penetrates the exterior panel 52, rainwater or the like passes through the oblique sheath tube guide 54 from the outdoor to the indoor. There is almost no risk of intrusion. In addition, since the water stop treatment by the O-ring 64 and the like is performed on the outdoor side opening of the sheath tube guide 54, there is no further risk of flooding.

  Further, the wall threading tool 51 has a sandwich structure in which the outer panel 52 is sandwiched from the thickness direction by the flange portion 61 of the sheath tube guide 54 and the wall presser 55, so that it can be easily stopped using the water stop packing 63. Water treatment can be performed, and plugging treatment such as backfilling work between the installation hole 53 and the wall threading tool 51 can be eliminated, and workability is good. In addition, since the tightening 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 threading tool 51 is attached and used in accordance with the thickness change of the exterior panel 52. Can do. In addition, due to the sandwich structure, not only when the pipe 4 is newly passed through the sheath guide 54, but also when the old pipe 4 is replaced with a new pipe, the pipe 4 or the sheath pipe 5 is replaced with the sheath guide. 54, the operating force applied when passing through 54, etc. is spread by the outer panel 52 by spreading to the flange 61 or the wall holder 55 hooked to the outer panel 52 on the upstream side in the operation direction of pushing in or pulling out the piping or the like. Can support. Therefore, the wall threading tool 51 is not inadvertently detached from the exterior panel 52, and the joint between the exterior panel 52 and the flange portion 61 and the wall presser 55 sandwiching the exterior panel 52 is not loosened. Can be lowered.

Further, by adopting the wall threading tool 51 having the above-described configuration, it is not necessary to provide a large circular hole in the exterior panel 52, and a decrease in strength of the exterior panel 52 due to the provision of the oblique installation hole 53 can be suppressed. Moreover, in this embodiment , since the fastening nut 56 is used as a fixing means for adopting and tightening the sandwich structure, the fixing parts and labor required for fixing to the exterior panel 52 are reduced, and the tightening operation is also rotated. Since it is easy to do, installation workability of the wall threading tool 51 to the exterior panel 52 is good.

The present invention is not limited to the one embodiment . For example, the pipes and the sheath pipes are not only drawn from the outside to the indoor through the outer wall of the house as described above, but conversely, they can be drawn from the inside to the outside.

Moreover, the thing which penetrates the outer wall of a house using the wall threading tool of the wall penetration piping of this invention and is arrange | positioned over the outdoors and indoors is not restricted to the liquid feeding pipe extended from a water heater etc., for example, a telephone line It may be a communication system cable such as a power system cable such as an electric wire. In this case, it is desirable to use various materials such as those having excellent anti-electromagnetic wave capability in accordance with the pipes and wires arranged through the interior of the sheath pipe .
