Description

  The present invention is, for example, a wall penetration for disposing a liquid feeding pipe extending from an outdoor device such as a water heater installed outdoors such as a detached house through an outer wall or the like that partitions the outdoor from an indoor. The present invention relates to a wall penetration structure for piping and a wall threading tool for wall penetration piping.

  2. Description of the Related Art Conventionally, a technique for drawing a pipe connected to a water heater installed outdoors in a house indoors is known (see, for example, Patent Document 1).

  In this prior art, a through-hole (installation hole) is provided in a wall, a fixture is attached to the through-hole from the outdoor side, and one end of a hot water supply pipe comprising a sheath pipe and a pipe passed through the sheath pipe is provided. It is attached to the indoor distributor (header), and only the piping is passed through the fixture and attached to the outdoor water heater.

At this time, a fixing tool is attached to the wall, a hot water supply pipe composed of a pipe and a sheath pipe is provided from the distributor (header) to the fixing tool, and the sheath pipe is cut at the position of the fixing tool. The part is brought into contact with the fixture, and the pipe is passed through a water-stopping member that projects obliquely upward to the outdoor side of the fixture, so that only this pipe passes through the wall, and the intermediate part of this pipe is fixed to the fixture. The piping drawn to the outdoor side is attached to the water heater.
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.

  Further, when the piping is pulled out to the outdoor side in the prior art, the pulling force acts on the outdoor side fixing tool, so that this force is concentrated on the fixing point of the fixing tool to the wall and the fixing tool is detached. Alternatively, the waterproofness between the fixture and the wall may be impaired.

  Furthermore, in the prior art, since the water stop member that penetrates only the pipe is inclined upward, it is suitable for inserting the pipe diagonally downward from the outdoor side, but not suitable for inserting diagonally upward. At the same time, there is a problem that workability is not good because it is necessary to pull up the pipe when the pipe is pulled out to the outside. Moreover, since the sheath tube is interrupted at the position of the fixture, there is a risk of water leakage.

  In the prior art, for example, an outdoor water heater is positioned above, and hot water supplied from the water heater or the like is guided from above to below as it goes indoors from the outdoors. For this reason, the piping is inclined from the upper side to the lower side as it goes indoors from the outdoors.

  When the piping is arranged to be inclined downward from above as it goes indoors from the outside, there is a risk that rainwater or the like may enter the indoor via the outer surface of the piping.

  The first problem to be solved by the present invention is that the sheath pipe can be penetrated through the wall of the house without forcibly bending it, and can be arranged along the wall, and the pipe passed through the sheath pipe is also bent forcibly. An object of the present invention is to obtain a wall through structure of a wall through pipe and a wall through tool of the wall through pipe that can be disposed without any problem.

  A second problem to be solved by the present invention is to obtain a wall through structure of a wall through pipe that can prevent intrusion of rainwater or the like in solving the first problem.

  Further, the third problem to be solved by the present invention is to solve the first problem by obtaining a wall through structure of a wall through pipe that can prevent indoor inundation even when a water leak occurs. There is.

  A wall threading tool for a wall through pipe according to the invention of claim 1 is inserted into an installation hole that obliquely penetrates a wall of a house, has a flange portion that hooks on one surface of the wall, and the wall The flange that is provided by being slidably fitted to the outer periphery of a cylindrical sheath tube guide through which a sheath tube that penetrates without interruption is passed, and the portion of the sheath tube guide that projects obliquely from the other surface of the wall And a fixing means provided between the wall press and the sheath tube guide to hold the wall press against the wall.

(Embodiment 1)
Hereinafter, the wall threading tool of the wall through pipe according to the first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a cross-sectional view illustrating a state in which a wall threading tool 1 of a wall through pipe according to a first embodiment is attached to an installation hole 3 in 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 part 12 so that the insertion angle with respect to the outer wall 2 of the pipe 4 and the sheath pipe 5 passing through the pipe 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 the first embodiment 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 in the future. When it is necessary to remove the wall through tool 1, the wall threading tool 1 of the 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 less resistance using the sheath pipe 5 as a guide as in the 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.

  Also, 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 hole 3 is 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.

Next, a wall threading tool 51 for a wall through pipe according to a fifth embodiment of the present invention will be described with reference to FIG. In addition, since it is the same as that of the said 1st Embodiment including the part which is not shown in FIG. 11 except the wall threading tool 51 and the wall installation hole 53 which are demonstrated below, about the same parts, such as a sheath pipe and piping In the description, the same reference numerals as those in the first embodiment are attached, the description thereof is omitted, and only different portions will be described.

  The wall of the house where the wall threading tool 51 according to the fifth embodiment is installed, in the case of this embodiment, penetrates diagonally at a predetermined position of the exterior panel (outer wall) 52 of the house made by the prefabricated method. An installation hole 53 having a circular cross section is formed. 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 concave portions or convex portions 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, and these are provided along the extending direction of each other, that is, in the axial direction. The wall presser 55 may be slidably fitted to prevent the wall presser 55 from rotating relative to the sheath tube guide 54. In this case, the wall presser 55 is rotated in accordance 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. 11, reference numeral 64 denotes an O-ring provided between the end surface 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, instead of the O-ring 64, a caulking process may be applied to the sheath tube passage hole 56a portion to constitute a water stop means between the sheath tube guide 54 and the sheath tube 5.

  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 first embodiment.

  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 is installed by adjusting the distance between the wall presser 55 and the flange portion 61 by moving the wall presser 55 in the axial direction. it can. 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. When water is stopped by the caulking process, the caulking material may be filled between the sheath tube through hole 56a and the sheath tube 5 without removing the tightening nut 56.

  The connection work other than the above points is the same as in the first embodiment. 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 less resistance using the sheath pipe 5 as a guide as in the 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

  Further, 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 be supported. 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 the fifth embodiment, since the tightening nut 56 is used as a fixing means for adopting and tightening the sandwich structure, there are few fixing parts and labor required for fixing to the exterior panel 52, and the tightening operation is also reduced. Since it only moves and is easy, the installation workability of the wall threading tool 51 to the exterior panel 52 is good. However, as a fixing means in the fifth embodiment, instead of a tightening nut, a lever that is attached to the outer surface of the sheath tube guide 54 in advance so as to be pivotable is operated, so that a wall pressing is performed by the cam portion of this lever. It is also possible to employ a lever-type clamp that presses and moves 55 to the exterior panel 52 side to give a tightening force (a force to sandwich the exterior panel 52 between the flange portion 61 and the wall presser 55).

The wall press 75 may be slidable at least in the axial direction of the guide tube portion 74a. For example, one or more recesses or projections extending in the axial direction are provided on the outer peripheral surface of the protruding portion of the sheath guide 74 and the inner peripheral surface of the wall retainer 75, and these are provided along the axial direction of the wall threading tool 71. The wall presser 75 may be prevented from rotating with respect to the guide tube portion 74a by being slidably unevenly fitted.

  The wall retainer 75 integrally has a flange portion 75 a along the wall surface of the exterior panel 72. The flange portion 75a has a circular shape (see FIG. 14) and is provided to project outward along a direction intersecting the axis of the wall retainer 75. Screw holes (not shown) are formed at a plurality of locations. ing. A waterproof seal 77 having the same shape as this is bonded to the flange portion 75a. The packing 77 is used as a water stop means between the installation hole 73 and the sheath tube guide 74, but may be adhered to the outer surface of the exterior panel 72, or the flange portion 74 b and the exterior panel 72. You may pinch | interpose between these, without adhering to either of outer surfaces. Note that, instead of the water-stopping packing 77, a caulking process may be performed over the flange portion 75a and the outer surface of the exterior panel 72.

  Next, the arrangement | positioning operation | work of the piping 4 and the sheath tube 5 using the wall threading tool 71 of the wall penetration piping of the said structure is demonstrated. First, a procedure for installing the wall threading tool 71 on the exterior panel 72 will be described.

  The sheath tube guide 74 is inserted into the installation hole 73 from the indoor side of the exterior panel 72 with the end portion of the guide tube portion 74a without the flange portion 74b as the head. This insertion is performed until the flange portion 74b is caught by the hole edge of the installation hole 73 on the inner wall surface of the exterior panel 72, so that the guide tube portion 74a faces the exterior panel 72 obliquely downward as it goes from the indoor side to the outdoor side. To penetrate. In this state, screws 78 that are passed through screw holes (not shown) of the flange portion 74 b and screwed into the exterior panel 72 are tightened to fix the sheath tube guide 74 to the exterior panel 72.

  In the installation operation, the wall retainer 75 fitted to the end of the sheath guide 74 protruding obliquely downward from the outer wall surface of the exterior panel 72 is slidable in the axial direction, and the wall Since the retainer 75 is screwed to the exterior panel 72, the wall retainer 75 is moved in the axial direction to move the wall retainer 75 as described above regardless of whether the exterior panel 72 has a thickness of, for example, 75 mm or 100 mm. 71 can be installed. That is, the wall threading tool 71 according to this 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 5 obliquely with respect to the exterior panel 72 through the guide tube portion 74a of the sheath tube guide 74 that obliquely penetrates the exterior panel 72 from the inner wall surface side of the exterior panel 72, for example. Then, the pipe 4 is inserted into the sheath pipe 5 from the outer surface side of the exterior panel 72, thereby leading the pipe 4 to a predetermined place through the sheath pipe 5.

  In this case, a tapered surface 76 is provided at the indoor side end portion of the guide tube portion 74a, and not only the entrance for penetrating the sheath tube 5 from the indoor side to the wall threading tool 71 is widened, but also the guide tube. Since the portion 74a is an oblique straight tube that has no seam in the middle and penetrates the exterior panel 72, the sheath tube 5 is inserted into the guide tube portion 74a when the sheath tube 5 is inserted into the tube portion 74a (regardless of the insertion direction). There is no fear of being caught, and therefore the workability of inserting the sheath tube 5 is good. In this installed state, when water stoppage between the sheath tube guide 74 and the sheath tube 5 is required, a caulking material (not shown) is filled over the end portion of the guide tube portion 74a protruding to the outside and the sheath tube 5. To do so.

  The connection work other than the above points is the same as in the first embodiment. In addition, since the wall threading tool 71 can be mounted and placed in advance on the exterior panel 72 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 71 on the exterior panel 72 is not required, and therefore the operation of arranging the sheath tube 5 and the pipe 4 at the construction site can be started quickly.

  According to the arrangement work of the pipe 4 and the sheath pipe 5 using the wall threading tool 71 of the wall through pipe described above, the sheath pipe 5 is passed through the sheath pipe guide 74 provided obliquely through the exterior panel 72. Thus, 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 even in the narrow wall space on the indoor side of the exterior panel 72 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 less resistance using the sheath pipe 5 as a guide as in the 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 72 by employing the wall threading tool 71, 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 72 is on the exterior side of the exterior panel 72, the joint portion easily leaks. There is no risk of flooding indoors even if water leaks from the water.

  Further, since the sheath tube guide 74 is provided so as to be inclined obliquely downward toward the outdoor side and penetrates the exterior panel 72, rainwater or the like passes through the oblique sheath tube guide 74 from the outdoor to the indoor. There is almost no risk of intrusion.

  Further, since the wall threading tool 71 has a sandwich structure in which the outer panel 72 is sandwiched from the thickness direction by the flange portion 74b of the sheath tube guide 74 and the flange portion 75a of the wall retainer 75, the water stop packing 77 is used. Thus, the water stop process can be easily performed, and the plugging process such as the backfilling operation between the installation hole 73 and the wall threading tool 71 can be omitted, and the workability is good. Moreover, due to the sandwich structure, not only when the pipe 4 is newly passed through the sheath guide 74, but also when the aged pipe 4 is replaced with a new pipe, the pipe 4 and the sheath pipe 5 are replaced with the sheath pipe. The operating force applied when passing through the guide 74 and the like is spread by the exterior panel 72 by spreading 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 piping or the like. I can support it. Therefore, the wall threading tool 71 is not inadvertently detached from the exterior panel 72, or the joint between the exterior panel 72 and the flange portion 74b or 75a sandwiching the exterior panel 72 is not loosened. .

  Further, by adopting the wall threading tool 71 having the above-described configuration, it is not necessary to provide a large circular hole in the exterior panel 72, and a decrease in strength of the exterior panel 72 due to the provision of the oblique installation hole 73 can be suppressed. Moreover, since the wall threading tool 71 according to the sixth embodiment requires only two components, the structure is simple and can be provided at a low cost, and the fixing to the exterior panel 72 is also a normal screwing operation. This can be done easily.

(Embodiment 7)
Next, a wall threading tool 81 for a wall through pipe according to a seventh embodiment of the present invention will be described with reference to FIGS. In addition, since it is the same as that of the said 1st Embodiment including the part which is not shown by FIGS. 15-17 except the wall threading tool 81 and the wall installation hole 83 which are demonstrated below, it is the same, such as a sheath pipe and piping. In the description of the parts, the same reference numerals as those in the first embodiment are attached and the description thereof is omitted, and only different parts will be described.

  Section of the wall of the house where the wall threading tool 81 according to the seventh embodiment is installed, in the case of this embodiment, obliquely penetrating to a predetermined position of the exterior panel (outer wall) 82 of the house made by the prefabricated construction method A circular installation hole 83 is formed. The hole 83 is inclined so as to gradually fall from the indoor side to the outdoor side, and the wall penetration angle θ is 45 °. The wall threading tool 81 includes first and second sheath tube guides 84 and 85, a first hooking portion 86, and a plurality of second hooking portions 87 to 89.

  The first sheath tube guide 84 made of metal or hard synthetic resin forms a circular shape continuously in the circumferential direction on the outer periphery of one end of the guide tube portion 84a made of a cylinder shorter than the thickness of the exterior panel 82 (see FIG. 16). The flange portion 84b is integrally formed. The outer diameter of the guide tube portion 84 a is smaller than the diameter of the installation hole 83. The flange portion 84b is provided so as to project outward along a direction intersecting the axis of the guide tube portion 84a, and screw holes (not shown) are formed at a plurality of locations.

  Similarly, the second sheath tube guide 85 made of metal or hard synthetic resin also has a circular shape continuously in the circumferential direction on the outer periphery of one end portion of the guide tube portion 85a formed of a cylinder shorter than the thickness of the exterior panel 82 (see FIG. 17) The flange portion 85b is integrally formed. 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 of the distal end portion of the guide tube portion 85a. ing. The guide tube portions 84a and 85a are fitted in the installation hole 83. The flange portion 85b is provided so as to project 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 hooking portion 86 is integrally provided continuously in the circumferential direction on the fitting portion of the second sheath tube guide 85 with respect to the first sheath tube guide 84, that is, on the inner peripheral surface of the end portion of the guide tube portion 85a. For example, it is formed by a protrusion having a triangular cross section. The plurality of second hook portions 87 to 89 that can be engaged with and disengaged from the first hook portion 86 are fitting portions of the first sheath tube guide 84 with respect to the second sheath tube guide 85, that is, the outer periphery of the guide tube portion 84a. It is provided on the surface continuously and integrally in the circumferential direction, and is formed by, for example, a protrusion having a triangular cross section. The second hooks 87 to 89 are spaced apart from each other in the axial direction of the guide tube portion 84a.

  These 2nd hook parts 87-89 are provided corresponding to the thickness of exterior panel 82, and when it catches on the 1st hook part 86, both sheath guides 84 and 85 according to it are corresponding. The wall threading tool 81 is assembled by obtaining the fitting depth and adapting the exterior panels 82 having different thicknesses.

  In other words, several types of prefabricated housing exterior panels 82 with different thicknesses are prepared, and one of them is selected and used. To the exterior panel 82 having the maximum thickness (for example, 100 mm). 15, the length of the wall threading tool 81 is extended and adapted by hooking the first hooking portion 86 and the second hooking portion 89 as shown in FIG. 15, and the minimum thickness (for example, 75 mm) is applied. In application to the exterior panel 82, the first hook portion 86 and the second hook portion 87 are hooked to reduce the length of the wall threading tool 81, and the outer thickness of these intermediate thicknesses is adapted. In application to the panel 82, the length of the wall threading tool 81 can be adapted by hooking the first hook portion 86 and the second hook portion 87. That is, the wall threading tool 81 according to this embodiment can be easily adapted to be installed on various exterior panels 82 having different thicknesses.

  It should be noted that such a function of adapting to a plurality of wall thicknesses is not essential, and at least one of the first and second hooks is sufficient, and these hooking structures include those of the first and second hooks. Both of them may be formed by not only the protrusions as in the present embodiment but one of the protrusions and the other of the corresponding grooves. However, in the case where the protrusion has a triangular cross section as in the present embodiment, not only the first and second hook portions are smoothly engaged and disengaged by the inclined surfaces, but also the two guide tube portions 84a and 85a It is excellent in that the resistance in fitting can be limited only to the engaging position of the catching portion. Note that when engaging and disengaging these, both guide tube portions 84a and 85a are accompanied by some elastic deformation.

  Next, the arrangement | positioning operation | work of the piping 4 and the sheath tube 5 using the wall through tool 81 of the wall penetration piping of the said structure is demonstrated. First, a procedure for installing the wall threading tool 81 on the exterior panel 82 will be described.

  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 the guide tube portion 84a without the flange portion 84b as the head. This insertion is performed until the flange portion 84b is caught on the hole edge of the installation hole 83 on the inner wall surface of the exterior panel 82, whereby the guide tube portion 84a faces the exterior panel 82 obliquely downward as it goes from the indoor side to the outdoor side. It is accommodated in the installation hole 83 in such a posture. In this state, the first sheath tube guide 84 is fixed to the exterior panel 82 by tightening the screws 90 that are passed through screw holes (not shown) of the flange portion 84 b and screwed into the exterior panel 82. In this installed state, the outer peripheral surface of the guide tube portion 84a and the inner peripheral surface of the installation hole 83 are not in contact with each other, and a gap g is provided between them as shown in FIG.

  In addition to the configuration of the present embodiment, a case where the spacer step portion having the same diameter as the installation hole 83 is provided continuously or discontinuously in the circumferential direction on the outer periphery of the base portion on the flange portion 84b side of the guide tube portion 84a. In addition, the guide tube portion 84a can be positioned with respect to the radial direction of the installation hole 83 by this step portion. Therefore, the guide tube 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 the fitting with the second sheath tube guide 85 described below. In addition, since it is possible to prevent mutual interference such that the tips of the guide tube portions 84a and 85a come into contact with each other, it is excellent in that the installation workability of the wall threading tool 81 can be facilitated.

  Next, the second casing tube guide 85 is inserted from the outdoor side of the exterior panel 82 into the installation hole 83 along the inner peripheral surface with the end of the guide tube portion 85a without the flange portion 85b at the top. . This insertion is performed until the flange portion 85b is caught on the edge of the installation hole 83 on the outer wall surface of the exterior panel 82, whereby the guide tube portion 85a is inclined upward as the exterior panel 82 is moved from the outdoor side to the indoor side. It is accommodated in the installation hole 83 in such a posture.

  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 is 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 gets 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 catches (see FIG. 15). Since the second sheath tube guide 85 is connected to the first sheath tube guide 84 by the engagement of these hook portions 86 and 89, even if the second sheath tube guide 85 is released after the above insertion operation is finished, The guide 85 does not fall off obliquely downward.

  Then, in a state where the two sheath tube guides 84 and 85 are connected in this manner, the screws 91 that are passed through the screw through holes (not shown) of the flange portion 85b of the second sheath tube guide 85 and screwed into the exterior panel 82 are respectively tightened. Then, the second sheath tube guide 85 is fixed to the exterior panel 82. In this case, as described above, the second sheath tube guide 85 is supported by the first sheath tube guide 84 so that the second sheath tube guide 85 does not fall off. However, since there is no trouble of performing the work, it can be easily screwed.

  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 surrounding exterior panel 82 to perform a water stop treatment. Accordingly, it is possible to prevent water from entering between the installation hole 83 and the second sheath tube guide 85 from the outside. Instead of the water stop treatment, a water stop packing can be bonded between the flange portion 85b and the outer surface of the exterior panel 82.

  Through the above procedure, the wall threading tool 81 is installed through the exterior panel 82 obliquely with the exterior panel 82 sandwiched between the flange portions 84b and 85a.

  Thereafter, the guide tube portions 84a and 85a of the wall threading tool 81 including the first and second sheath tube guides 84 and 85 obliquely passing through the mutually connected exterior panels 82 are connected to the guide tube portions 84a and 85a of the exterior panel 82, for example. After the sheath tube 5 is obliquely penetrated with respect to the exterior panel 82 through the sheath tube 5 from the inner wall surface side, the pipe 4 is inserted into the sheath tube 5 from the outer surface side of the exterior panel 82, whereby the sheath tube The pipe 4 is led and arranged at a predetermined place through the inside 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 passes through the wall threading tool 81 from the indoor side. The sheath tube 5 is not likely to be caught at the tip of the guide tube portion 85a, and therefore the workability of inserting the sheath tube 5 is good. In this installation state, when water is shut off between the sheath pipe guide 85 and the sheath pipe 5 on the outdoor side, it may be performed by filling a caulking material (not shown) over them.

  The connection work other than the above points is the same as in the first embodiment. In addition, since the wall threading tool 81 can be mounted and placed in advance on the exterior panel 82 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 81 on the exterior panel 82 is not required, and therefore the operation of arranging the sheath pipe 5 and the pipe 4 at the construction site can be started quickly.

  According to the arrangement work of the pipe 4 and the sheath tube 5 using the wall threading tool 81 of the wall penetration pipe described above, the sheath pipe 5 is passed through the wall threading tool 81 provided obliquely through the exterior panel 82. Thus, the sheath tube 5 can be arranged indoors along the inner wall surface of the exterior panel 82, and the sheath tube 5 is forcibly bent in the narrow wall space on the indoor side of the exterior panel 82 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 less resistance using the sheath pipe 5 as a guide as in the 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 82 by employing the wall threading tool 81, 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 82 is on the exterior side of the exterior panel 82, the joint portion easily leaks. There is no risk of flooding indoors even if water leaks from the water.

  Further, the second outer sheath guide 85 on the outdoor side is inclined so as to be inclined downward toward the outdoor side, and the exterior panel 82 is screwed, so that rainwater or the like is a guide tube portion in the diagonal wall threading tool 81. There is almost no risk of entering the indoors from the outdoors through 84a and 85a.

  Further, since the wall threading tool 81 has a sandwich structure in which the outer panel 82 is sandwiched from the thickness direction by the flange portions 84b and 85b of the first and second sheath tube guides 84 and 85, the installation hole 83 and the wall A plugging process such as a backfilling operation between the guide tube portions 84a and 85a of the threading tool 81 can be made unnecessary, and the workability is good. Moreover, due to the sandwich structure, not only when the pipe 4 is newly passed through the sheath guides 84 and 85, but also when the old pipe 4 is replaced with a new pipe, the pipe 4 and the sheath pipe 5 are The operating force applied when passing through the wall threading tool 81 is propagated to the flange portion 84b or 85b hooked to the exterior panel 82 on the upstream side in the operation direction in which the piping 4 or the like is pushed in or pulled out. Can be dispersed and supported. Therefore, the wall threading tool 81 is not inadvertently detached from the exterior panel 82 or the joint between the exterior panel 82 and the flange portion 84b or 85b sandwiching the exterior panel 82 is not loosened. .

  In addition, by adopting the wall threading tool 81 having the above-described configuration, it is not necessary to provide a large circular hole in the exterior panel 82, and it is possible to suppress a decrease in strength of the exterior panel 82 due to the provision of the oblique installation hole 83. Moreover, since the wall threading tool 81 according to the seventh embodiment requires only two components, the structure is simple and can be provided at a low cost, and the fixing to the exterior panel 82 is also a normal screwing operation. This can be done easily. In the seventh embodiment, the means for fixing the flange portions 84b and 85b to the exterior panel 82 may be an adhesive means such as an adhesive or a double-sided adhesive tape instead of screwing. In the case where the connection strength due to the hooking between the first hooking portion 86 and the second hooking portions 87 to 89 is large, and both the flange portions 84b and 85b are pressed against the inner and outer wall surfaces of the exterior panel 82, respectively, The fixing means may be omitted.

(Embodiment 8)
Next, a wall threading tool 101 of a wall through pipe according to a seventh embodiment of the present invention will be described with reference to FIG. In addition, since it is the same as that of the said 1st Embodiment including the part which is not shown in FIG. 18 except the wall threading tool 101 and the wall installation hole 103 which are demonstrated below, about the same parts, such as a sheath pipe and piping, In the description, the same reference numerals as those in the first embodiment are attached, the description thereof is omitted, and only different portions will be described.

  Section of the wall of the house where the wall threading tool 101 according to the eighth embodiment is installed, in the case of this embodiment, obliquely penetrates to a predetermined position of the exterior panel (outer wall) 102 of the house made by the prefabricated method A circular installation hole 103 is opened. The hole 103 is inclined so as to gradually fall from the indoor side to the outdoor side, and the wall penetration angle θ is 45 °. The wall threading tool 101 is formed of a single part integrally formed of metal or hard synthetic resin, and includes a sheath tube guide 104 and a flange portion 105.

  Specifically, the sheath tube guide 104 is formed of a cylinder shorter than the thickness of the exterior panel 102, and a flange portion 105 that is continuously circular in the circumferential direction is integrally provided on the outer periphery of one end portion thereof. The outer diameter of the sheath tube guide 104 is substantially equal to the hole diameter of the installation hole 103, and a tapered surface 104 a is provided on the inner peripheral surface of the end portion of the sheath tube guide 104 without the flange portion 105. The flange portion 105 is provided so as to project outward along a direction intersecting the axis of the sheath guide 104, and screw holes (not shown) are formed at a plurality of locations.

  Next, the arrangement | positioning operation | work of the piping 4 and the sheath tube 5 using the wall threading tool 101 of the wall penetration piping of the said structure is demonstrated. First, a procedure for installing the wall threading tool 101 on the exterior panel 102 will be described.

  The wall threading tool 101 is inserted into the installation hole 103 from the exterior side of the exterior panel 102 with the end of the sheath tube guide 104 having the tapered surface 104a at 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 caught by 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 a posture that is inclined upward. In this state, the screws 106 passed through the screw through holes (not shown) of the flange portion 105 and screwed into the exterior panel 102 are tightened to fix the wall threading 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 surrounding exterior panel 102 to perform a water stop treatment. Accordingly, it is possible to prevent water from entering between the installation hole 103 and the wall threading tool 101 from the outside. Instead of this water stop treatment, a water stop packing can be bonded between the flange portion 105 and the outer surface of the exterior panel 102.

  The wall threading tool 101 is installed through the exterior panel 102 obliquely by the above procedure.

  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 through the sheath tube 5 obliquely with respect to the exterior panel 102, and then the exterior panel 102 is inserted into the sheath tube 5. By inserting the pipe 4 from the outer surface side of the pipe, the pipe 4 is led to a predetermined place through the inside of the sheath pipe 5.

There is little fear, therefore, the workability of inserting the sheath tube 5 is good. In this installed state, when water is stopped between the wall threading tool 101 and the sheath tube 5 on the outdoor side, it may be performed by filling a caulking material (not shown) over them.

  The connection work other than the above points is the same as in the first embodiment. Further, since the wall threading tool 101 can be mounted and placed in advance on the exterior panel 102 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 101 on the exterior panel 102 is not 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 arrangement work of the pipe 4 and the sheath tube 5 using the wall threading tool 101 of the wall penetration pipe described above, the sheath pipe 5 is passed through the wall threading tool 101 provided obliquely through the exterior panel 102. Thus, the sheath tube 5 can be disposed indoors along the inner wall surface of the exterior panel 102, and the sheath tube 5 is forcibly bent in the narrow wall space on the indoor side of the exterior panel 102 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 less resistance using the sheath pipe 5 as a guide as in the 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 102 by using the wall threading tool 101, the sheath tube can be used even if water leaks from the piping 4 indoors. The joint portion that is discharged to the outside through the interior of the interior 5 and is less likely to be flooded indoors, and the joint portion for the pipe 4 penetrating the exterior panel 102 is on the outdoor side of the exterior panel 102, so that the joint portion easily leaks. There is no risk of flooding indoors even if water leaks from the water.

  Further, since the wall threading tool 101 is inclined so as to be inclined obliquely toward the outdoor side and is screwed to the exterior panel 102, rainwater or the like passes through the sheath tube guide 104 of the oblique wall threading tool 101 and is outdoors. There is almost no risk of entering the house indoors. Further, since the wall threading tool 101 covers and conceals the opening on the outdoor side of the installation hole 103 with the flange portion 105, plugging processing such as backfilling work between the installation hole 103 and the sheath guide 104 is unnecessary. Yes, workability is good.

  Further, by adopting the wall threading tool 101 having the above-described configuration, it is not necessary to provide a large circular hole in the exterior panel 102, and a decrease in strength of the exterior panel 102 due to the provision of the oblique installation hole 103 can be suppressed. Moreover, since the wall threading tool 101 according to the eighth embodiment requires only one component, the structure is extremely simple and can be provided at a lower cost, and the fixing to the exterior panel 102 is also possible with an ordinary screw. It can be easily performed by a stop operation. In the eighth embodiment, as means for fixing the flange portion 105 to the exterior panel 102, an adhesive means such as an adhesive or a double-sided adhesive tape can be used instead of screwing.

Further, the first wall passing member 6 is provided with a closing portion 12 at one end portion 8a exposed to the outdoor O side of the first cylindrical portion 8 when the wall threading tool 1 is attached to the installation hole 3.

  The sheath tube guide 13 is formed so as to protrude from the closed portion 12 on the outdoor O side and obliquely upward. The sheath tube guide 13 protrudes from the end portion of the closing portion 12 positioned above the axis P. A smoothly curved surface 110 is formed at the joint between the sheath guide 13 and the closing portion 12 inside the first tube portion 8. The sheath tube guide 13 does not protrude from the inner surface 12 a of the closing portion 12 to the inside of the first tube portion 8.

  A water-stop packing 14 is provided on the outer peripheral surface of the first cylinder portion 8 over the entire circumference. This water-stopping packing 14 fills a gap G between the first tube portion 8 and the inner surface of the installation hole 3, and prevents intrusion of rainwater or the like passing through the gap G into the indoor I. The gap G may be filled using a known caulking material instead of the water stop packing 14.

  A flange mounting portion 111 is formed on the other end portion 8 b located on the indoor I side of the sheath guide 13. A flange member 112 hooked to the hole edge of the installation hole 3 is attached to the flange attachment portion 111.

  The flange mounting portion 111 includes a plurality of concave grooves 113 formed on the outer peripheral surface of the first cylindrical portion 8 and formed concavely from the outer peripheral surface. In the illustrated example, the flange mounting portion 111 includes two concave grooves 113. Each concave groove 113 is formed along the circumferential direction of the first cylindrical portion 8 on the outer peripheral surface of the other end portion 8b at least on the side where the sheath tube guide 13 is provided from the axis P. Each concave groove 113 is formed along the outer wall 2 when the wall threading tool 1 is attached to the installation hole 3.

  Each of the concave grooves 113 is preferably formed at a position where the distance from the surface 12b of the blocking portion 12 corresponds to the thickness of the outer wall 2 to which the wall threading tool 1 is attached. The concave groove 113 is formed at a position where the distances from the surface 12b of the closing portion 12 are different from each other. Further, each of the concave grooves 113 is not formed on the outer peripheral surface of the other end portion 8b on the side where the sheath pipe guide 13 is not disposed from the axis P.

  The flange member 112 is formed in a horseshoe shape and engages with the concave groove 113. The flange member 112 engages with the groove 113 from above when the wall threading tool 1 is fitted into the installation hole 3. When the flange member 112 is engaged with the concave groove 113, the end surface thereof is caught by the hole edge of the installation hole 3.

  A plurality of through holes 114 are formed in the flange member 112. A screw 115 for fixing the flange member 112 to the outer wall 2 passes through each of these through holes 114.

  The first tube portion 8 is formed so as to be inclined gradually toward the outer surface side of the outer wall 2 as the edge portion 8c of the other end portion 8b is directed downward from above, that is, as the edge portion 8c is separated from the sheath guide 13. Has been. In the other end portion 8b, the edge portion 8c on the side where the sheath tube guide 13 is provided from the axis P projects from the outer wall 2 toward the indoor I side, and the sheath tube guide 13 is not disposed from the axis P. The side edge 8 c is formed so as to be located in the installation hole 3 from the hole edge of the installation hole 3.

  The example of a specific dimension of the said wall threading tool 1 is shown. Since the installation hole 3 does not reduce the mechanical strength of the outer wall 2 as much as possible, it is desirable to make the diameter as small as possible. 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 penetrates the outer wall 2 having a thickness of 75 mm to 100 mm, the pipe 4 passing through the outer wall 2 and the axis P of the sheath pipe 5 with respect to the axis P The sheath tube guide 13 is provided with respect to the closing portion 12 so that the insertion angle θ ′ is 23 °. At this time, it is desirable that the diameter of the installation hole 3 is formed to a diameter of 100 mm.

  Next, an operation of attaching the outer wall 2 of the wall threading tool 1 according to the ninth embodiment to the installation hole 3 will be described.

  First, the first wall passing member 6 is fitted into the installation hole 3 from the outdoor O side so that the blocking portion 12 is exposed to the outdoor O. The flange member 112 is engaged with the concave groove 113 corresponding to the thickness of the outer wall 2 from above. The screw 115 is passed through the through hole 114 and screwed into the outer wall 2, and the first wall passing member 6 is fixed to the outer wall 2 together with the flange member 112. At this time, the gap G between the first cylindrical portion 8 and the installation hole 3 is filled by the water blocking packing 14 without any gap. Thus, the attachment of the wall threading tool 1 of the wall through pipe of the ninth embodiment to the installation hole 3 of the outer wall 2 is completed.

  After fixing the wall threading tool 1 to the outer wall 2, the sheath tube 5 and the pipe 4 are sequentially inserted into the sheath tube guide 13 from the indoor I side. A pipe 116 connected to a water heater installed on the second floor or the like is connected to the end of the pipe 4 protruding from the distal end portion 13 a of the sheath pipe guide 13 through a joint 32. When this connection is performed, the joint portion 117 shown below is used in the illustrated example.

  The joint portion 117 includes the joint 32, a thread groove 118 formed on the outer periphery of the distal end portion 13a of the sheath tube guide 13, a joint fixing member 119 that is screwed into the thread groove 118, and the like. The joint 32 is integrally provided with a flange 120 made of metal and abutting against the opening edge 13 b of the sheath tube guide 13. The flange 120 is provided over the entire circumference of the joint 32.

  The joint fixing member 119 is made of a synthetic resin or the like and is formed in an annular shape that allows the joint 32 to pass through the inner periphery thereof. The joint fixing member 119 is formed in a cylindrical shape and is screwed into the screw groove 118 of the sheath tube guide 13, and an annular ring portion extending from one end of the screw portion 121 toward the inner peripheral side. 122 are integrally provided. The annular portion 122 presses the flange portion 120 of the joint 32 toward the opening edge 13 b of the sheath tube guide 13 when the screw portion 121 is screwed into the screw groove 118.

  As described above, the joint portion 117 is formed by the joint fixing member 119 being screwed into the thread groove 118 of the sheath tube guide 13 and pressing the flange portion 120 of the joint 32 toward the opening edge 13b of the sheath tube guide 13. The opening of the sheath guide 13 is closed so that rainwater does not enter.

  According to the present embodiment, the width D along the vertical direction of the first tube portion 8 when fitted in the installation hole 3 is formed sufficiently larger than the outer diameter d of the sheath tube 5. A sufficiently large space S in which the 5 is forcibly bent and does not cause buckling deformation can be secured in the first tube portion 8. Further, the edge portion 8c on the side where the sheath guide 13 is not disposed from the axis P in the other end portion 8b located on the indoor I side of the first tube portion 8 is located in the installation hole 3 from the hole edge of the installation hole 3. positioned.

  For this reason, even if the back side space of the outer wall 2 is narrow, the sheath tube 5 is disposed along the outer wall 2 through the outer wall 2 without being bent excessively. Further, since the sheath tube 5 is not forcibly bent, the pipe 4 can be easily passed through the sheath tube 5.

  Moreover, since the installation hole 3 to which the wall threading tool 1 of this wall penetration pipe is attached penetrates along the direction orthogonal to the outer wall 2, rainwater or the like is transmitted through the outer surface of the first cylindrical portion 8 or the like. Intruding indoors. In the present embodiment, the installation hole 3 may be formed so as to penetrate the outer wall 2 so as to gradually go upward as it goes from the outdoor O to the indoor I. In this case, the intrusion of rainwater can be further prevented. At this time, it is desirable that the first cylindrical portion 8 is formed so as to be inclined so that its axis P gradually goes downward as it goes from the outdoor O to the indoor I.

  Further, the joint 32 that connects the pipe 4 and the pipe 116 connected to the hot water heater or the like is located in the outdoor O. The sheath tube 5 is inserted to the middle of the sheath tube guide 13. For this reason, even if a water leak occurs in the joint 32, it is possible to prevent water from entering the indoor I.

  Further, the flange member 112 is fixed to the outer wall 2 with screws 115 or the like. Therefore, not only when the sheath pipe 5 and the pipe 4 are newly passed through the sheath pipe guide 13, but also when the aged pipe 4 is replaced with a new one, the pipe 4 and the sheath pipe 5 are connected to the sheath pipe guide 13. The operating force applied when passing through the inside can be distributed to the flange member 112 and supported by the outer wall 2.

  For this reason, it can prevent that the wall threading tool 1 removes from the outer wall 2 etc. carelessly. Therefore, the installation state of the sheath pipe 5 to the outer wall 2 can be reliably maintained regardless of the insertion / extraction of the pipe 4.

  Further, the flange mounting portion 111 includes a plurality of concave grooves 113 having different distances from the surface 12 b of the closing portion 12. For this reason, according to the thickness of the outer wall 2, the concave groove 113 with which the flange member 112 is engaged is arbitrarily selected, so that it can be easily attached to the installation holes 3 formed in the outer walls 2 having different thicknesses. it can.

  In this example, the sheath tube 5 is inserted up to the stopper 13d that protrudes in the middle of the inner surface of the sheath tube guide 13, but the sheath tube 5 may be drawn out of the sheath tube guide 13. . In this case, the pipe 4 is also drawn out of the sheath pipe guide 13. In this way, it is possible to prevent water from entering the indoor I to a higher degree when water leaks from the connecting portion between the pipe 4 and the pipe 116.

(Embodiment 10)
Next, with reference to FIG. 22, a wall threading tool 1 for a wall through pipe according to a tenth embodiment of the present invention will be described. In addition, the same code | symbol is attached | subjected to the component same as the wall threading tool 1 of wall penetration piping which concerns on 9th Embodiment mentioned above, and description is abbreviate | omitted.

A thread groove 131 is formed on the outer periphery of the one end portion 8a of the first tube portion 8 of the wall threading tool 1 of the present embodiment. The second flange member 130 is formed in an annular shape, and a thread groove 132 that is screwed into the thread groove 131 is formed on the entire circumference of the second flange member 130.

  When attaching the wall threading tool 1 of the present embodiment to the installation hole 3, the second flange member 130 is attached to the first tube portion 8 in advance. The first cylinder portion 8 to which the second flange member 130 is attached is fitted into the installation hole 3. And it fixes to the outer wall 2 by the method similar to the wall threading tool 1 of 9th Embodiment mentioned above, and connects the piping 4 and the piping 116 connected with the water heater etc. mutually.

  According to the present embodiment, in addition to the effect of the wall threading tool 1 of the ninth embodiment described above, the outer wall 2 is attached with being sandwiched between the flange member 112 and the second flange member 130. For this reason, the operating force applied when the pipe 4 or the sheath tube 5 is passed through the sheath tube guide 13 spills over the flange member 112 and the second flange member 130 and can be supported more dispersedly by the outer wall 2.

  For this reason, it can prevent more reliably that the wall threading tool 1 removes from the outer wall 2 etc. carelessly. Therefore, the installation state of the sheath pipe 5 to the outer wall 2 can be more reliably maintained regardless of whether the pipe 4 is inserted or removed.

  Furthermore, by adjusting the screwing amount of the second flange member 130 into the first tube portion 8, it can be more easily attached to the installation holes 3 formed in the outer walls 2 having different thicknesses. Therefore, the installation property to the outer walls 2 having different thicknesses is further improved.

  The present invention is not limited to the first to tenth embodiments. For example, when attaching the wall through tool of the wall through pipe to the outer wall of the house in the first to tenth embodiments, if you do not want to make a hole in the outer wall directly with a screw, an adhesive with a high waterproof effect, etc. You may attach directly to the installation hole provided in the said outer wall using.

  In addition, as described above, the pipes and the sheath pipes are not only drawn through the outer wall of the house and drawn from the outside to the inside, but conversely, they can be drawn from the inside to the outside.

  Further, the wall penetration structure of the wall penetration pipe described in any of the embodiments described above includes a cylindrical sheath tube guide at least partially located in an installation hole that penetrates the wall of the house. It is arranged in an inclined posture with respect to the sheath tube guide, and the sheath tube is passed through the sheath tube obliquely with respect to the wall through the sheath tube in the inclination direction, and a pipe is passed through the sheath tube. .

  In order to configure this wall penetration structure, first, the cylindrical sheath tube guide is disposed in a posture inclined with respect to the wall of the house. In this arrangement, at least a portion of the sheath guide is positioned in an installation hole that penetrates the wall. Next, a sheath tube is penetrated from the one surface side of the wall through a sheath tube guide disposed obliquely with respect to the wall. Accordingly, the sheath pipe is provided through the installation hole along the inclination of the sheath pipe guide and obliquely penetrating the wall. Finally, by inserting a pipe inside the sheath pipe, a wall penetrating structure in which the sheath pipe and the pipe as the wall penetrating pipe are obliquely penetrated with respect to the wall is formed. It is arranged to the place.

  According to this wall penetrating structure, the sheath pipe penetrating the installation hole together with the inclination of the sheath pipe guide can be obliquely penetrated through the wall without being forcibly bent and disposed along the wall. Therefore, for example, it can be arranged without difficulty in the narrow wall space behind the outer wall, and a pipe guided through the inside of the sheath pipe can be arranged without being bent excessively.

  That is, according to the wall penetration structure of the wall penetration pipe, the sheath pipe is passed through the cylindrical sheath pipe guide provided obliquely with respect to the wall, and the sheath pipe is obliquely penetrated with respect to the wall. Since the sheath tube can be disposed along the wall without forcibly bending it, it is advantageous for disposing the sheath tube or the like in a narrow wall space, for example. Pipes can be arranged without being bent excessively.

  And since the pipe can be arranged in this way, when this pipe is a liquid feeding pipe and a liquid leaks from the pipe, the liquid leaking from the pipe is outdoors through a sheath pipe that obliquely penetrates the wall. Can be derived.

  Moreover, the wall threading tool of the wall through pipe described in any of the embodiments described above includes a first tube portion that fits into an installation hole that penetrates the wall of the house, and a closing portion that closes the inside of the first tube portion. And a cylindrical sheath tube guide that projects obliquely from the closed portion and through which the sheath tube passes through the wall.

Next, the sheath pipe is passed through the sheath guide from the other side or one side, and the wall is obliquely penetrated. Finally, a pipe is passed through the inside of the sheath pipe that has been disposed, and the pipe is obliquely penetrated through the wall, and is disposed through the sheath pipe to a predetermined place.

  The wall threading tool of this wall through pipe is provided with an oblique cylindrical sheath guide in the closed portion. By passing the sheath tube through the sheath tube guide, the sheath tube can be obliquely penetrated through the wall without being bent excessively, and disposed along the wall. Therefore, for example, it can be arranged without difficulty in the narrow wall space behind the outer wall, and the piping guided through the inside of the sheath tube can be arranged indoors without being bent excessively.

  That is, according to the wall threading tool of this wall through pipe, the sheath pipe can be passed through the slanted sheath pipe through the slanted sheath guide provided at the closed portion of the first cylindrical section, and the slanted pipe can be penetrated with respect to the wall. Since it can be arranged along the wall without forcibly bending the sheath pipe through which the pipe is passed, for example, it is advantageous for arranging the sheath pipe or the like inside the narrow wall space, The piping passed through the sheath tube can also be arranged without being bent excessively.

  Moreover, the wall threading tool of the wall through pipe described in any of the embodiments described above is a first tube portion that fits into an installation hole that penetrates the wall of the house, and is formed integrally with the first tube portion and outside. A first flange portion projecting out, a closed portion that closes the inside of the first tube portion, and a cylindrical sheath tube guide that projects obliquely from the closed portion and passes through the sheath tube that passes through the wall. A first wall passing member; a second wall passing member provided with a second flange portion projecting outward from a second cylindrical portion fitted into the installation hole from a side opposite to the first wall passing member; and the both flanges And connecting means for connecting the first and second wall passing members with the wall interposed therebetween.

  In this wall threader, first, one of the first and second wall threading members is fitted into the installation hole from one side of the wall, and the other is fitted into the installation hole from the other side of the wall. After that, the wall portion of the present invention is installed by connecting the first tube portion and the second tube portion by connecting means so as to sandwich the wall between the first flange portion and the second flange portion from both sides in the thickness direction. Install in the hole. Next, the sheath pipe is passed through the sheath guide from the other side or one side, and the wall is obliquely penetrated. Finally, a pipe is passed through the inside of the sheath pipe that has been disposed, and the pipe is obliquely penetrated through the wall, and is disposed through the sheath pipe to a predetermined place.

  The wall threading tool of this wall through pipe is provided with an oblique cylindrical sheath guide in the closed portion. By passing the sheath tube through the sheath tube guide, the sheath tube can be obliquely penetrated through the wall without being bent excessively, and disposed along the wall. Therefore, for example, a sheath pipe can be disposed without difficulty in the narrow wall space behind the outer wall, and piping guided through the interior of the sheath pipe can be disposed indoors without being bent excessively.

  In addition, since this wall threading tool has first and second flange portions that sandwich the wall from both sides in the thickness direction, not only when a new pipe is passed through the sheath pipe guide, but also an aged pipe. Even when replacing the pipe with a new one, the operating force applied when the pipe or sheath pipe is passed through the sheath pipe guide, etc., is spread to the flange section caught on the wall on the upstream side in the operation direction of pushing or pulling the pipe etc. Therefore, the operation force is difficult to concentrate on a fixing portion for fixing the wall passing member positioned on the downstream side in the insertion direction of piping or the like to the wall. Therefore, the wall threading tool does not come off from the wall inadvertently, and the joint between the wall and the first and second flange portions does not loosen, and thus the waterproofness is impaired when applied to the outer wall. Etc. can be reduced.

  That is, according to the wall threading tool of this wall through pipe, the wall can be penetrated diagonally by passing the sheath pipe through the slanted sheath guide provided in the first wall threading member, thereby allowing the pipe to pass inside. Since it is possible to dispose the sheath tube along the wall without forcibly bending it, it is advantageous to dispose the sheath tube or the like inside the narrow wall space, for example, and the pipe passed through the sheath tube Can be placed without bending. Furthermore, since it has the 1st flange part and 2nd flange part which pinch | interpose a wall and these support the operation force added at the time of insertion of a sheath pipe, the insertion / extraction of piping, etc. with this, carelessly from a wall While not coming off, the risk of loosening between the wall and the first and second flange portions can be reduced.

  Moreover, the wall threading tool of the wall through pipe described in any of the embodiments described above is characterized in that the distance between the first and second flange portions can be adjusted by the connecting means.

  In this wall threading tool, in addition to the effects described above, the distance between the first and second flange portions can be set to the wall thickness by adjusting the connecting means for connecting the first tube portion and the second tube portion. Can be adapted. Therefore, the present invention can be applied to the wall thickness within the range in which the connecting means can be adjusted, and it is not necessary to prepare various kinds of wall through pipes for the wall through pipes having different lengths of the first and second cylindrical portions.

  That is, according to the wall threading tool of this wall penetration pipe, in addition to the effect of the wall threading tool of the wall penetration pipe according to the invention of claim 3, the distance between the first and second flange portions sandwiching the wall is set. Since it can be attached to the wall by changing it, it is not necessary to prepare several types of wall through pipes for the wall through pipes with different lengths of the first and second tube parts, and absorbs variations in the wall thickness. Can be used.

  Further, the wall threading tool of the wall through pipe described in any of the embodiments described above, when the installation hole penetrates along the direction orthogonal to the wall of the house and is fitted into the installation hole The width of the first tube portion along the vertical direction is sufficiently larger than the outer diameter of the sheath tube, and the sheath tube guide is formed to project obliquely upward from the closed portion.

  Since this wall threading tool is formed so that the width along the vertical direction of the first tube portion is sufficiently larger than the outer diameter of the sheath tube when fitted into the installation hole of the house, the sheath tube is forcibly bent. Thus, a sufficiently wide space that does not cause buckling deformation can be secured in the first tube portion.

  Therefore, the sheath tube can be disposed along the wall by penetrating the wall without forcibly bending the sheath tube. Further, since the sheath tube is not forcibly bent, the pipe can be easily passed through the sheath tube.

  Moreover, since the installation hole to which the wall threading tool of this wall penetration pipe is attached penetrates along the direction orthogonal to the wall of the house, it is inclined downward from above as it goes indoors from the outdoors. Even when the sheath tube and the pipe are arranged, it is possible to prevent rainwater or the like from entering the indoors through the outer surface of the first tube portion.

At this time, the first tube portion is fitted so that the closed portion and the sheath tube guide are exposed to the outside. And a sheath pipe and piping are inserted toward the 1st cylinder part and a sheath pipe guide from an indoor side. A water heater is connected through a well-known joint or the like to a sheath tube exposed to the outside from the sheath tube guide and the tip of the pipe. Thus, the joint which mutually connects a water heater, a sheath pipe, and piping will be located outdoors. For this reason, even if a water leak occurs in this joint, it is possible to prevent water from entering the room.

  That is, according to the wall threading device of this wall through pipe, the width of the first tube portion along the vertical direction of the house is formed sufficiently larger than the outer diameter of the sheath tube, and the sheath tube is forcibly bent. Since a sufficiently wide space that does not cause buckling deformation can be secured in the first tube portion, the sheath tube can be disposed along the wall through the wall without forcibly bending the sheath tube. Further, since the sheath tube is not forcibly bent, the pipe can be easily passed through the sheath tube.

  In addition, since the installation hole penetrates along the direction orthogonal to the wall of the house, even when the sheath tube and the pipe are arranged by being inclined downward from above as it goes indoors from the outdoors, Prevents intrusion of rainwater and other indoors.

  Furthermore, since a water heater can be connected to the end of the sheath pipe and piping exposed from the sheath pipe guide to the outside via a well-known joint or the like, even if water leakage occurs in this joint, Can be prevented.

  Moreover, the wall threading tool of the wall through pipe according to any one of the embodiments described above is provided at one end of the first tube portion where the closing portion is exposed to the outside of the house, and the first tube portion A flange member that is attached to an outer periphery of at least the side where the sheath tube guide is disposed and hooks on a hole edge of the installation hole, and the sheath of the other end of the first cylindrical portion The edge on the side where the tube guide is not disposed is located in the installation hole from the hole edge.

  When this wall threading tool is fitted in the installation hole of the house, the width along the vertical direction of the first tube portion is formed sufficiently larger than the outer diameter of the sheath tube. For this reason, it is possible to ensure a sufficiently wide space in the first tube portion in which the sheath tube is forcibly bent and does not cause buckling deformation. Furthermore, the edge part by which the sheath pipe guide is not arrange | positioned among the other end parts located in the indoor side of the said 1st cylinder part is located in an installation hole rather than a hole edge.

  Therefore, the sheath tube can be disposed along the wall by penetrating the wall without forcibly bending the sheath tube. Further, since the sheath tube is not forcibly bent, the pipe can be easily passed through the sheath tube.

  Further, the wall threading tool of this through-wall piping can prevent intrusion of rainwater and the like, and can prevent inundation into the room even if water leakage occurs in the joint connecting the sheath tube and the piping and the water heater.

  When attaching this wall threading tool to the wall, after fitting the first tube portion from the outdoor side to the installation hole so that the blocking portion and the sheath tube guide are exposed to the outside, the other end of the first tube portion Attach the flange member to the part. The flange member is caught on the hole edge of the installation hole. It is desirable to fix the flange member to the wall by screwing or the like. In this way, the wall threader is attached to the wall of the house.

  This wall threading tool is used not only when new sheath pipes and pipes are passed through the sheath guides, but also when pipes and sheath pipes are passed through the sheath guides when replacing old pipes with new ones. The operating force applied to the surface can be dispersed and supported by the wall by spreading to the flange.

  For this reason, it is prevented that a wall threading tool removes carelessly from a wall etc. Therefore, it is possible to reliably maintain the installation state of the sheath tube on the wall regardless of whether the pipe is inserted or removed.

  That is, according to the wall threading tool of this wall through pipe, in addition, the edge on the side where the sheath tube guide is not arranged in the other end portion located on the indoor side of the first tube portion is the hole of the installation hole. Since it is located in the installation hole from the edge, it can be more easily arranged along the wall through the wall without forcibly bending the sheath tube. Further, since the sheath tube is not forcibly bent, the pipe can be easily passed through the sheath tube.

  The flange member can be attached to the wall by hooking on the edge of the installation hole and screwing the flange member to the wall. For this reason, the operating force applied when the sheath tube and the pipe are passed through the sheath tube guide can be dispersed and supported by the wall by spreading to the flange member. For this reason, it is prevented that a wall threading tool removes carelessly from a wall etc. Therefore, it is possible to reliably maintain the installation state of the sheath tube on the wall regardless of whether the pipe is inserted or removed.
