Description

  The present invention is attached to an end portion of a sheath pipe into which a plurality of water pipes such as water supply pipes, hot water supply pipes, circulation pipes, etc., and drain pipes piped in a detached house, an apartment house, etc. are inserted. The present invention relates to a tube outlet forming tool.

  In detached houses and apartment houses, water pipes such as water and hot water pipes and resin pipes such as drain pipes are used to supply water and hot water to the kitchen, bathroom, vanity, etc., and for hot water floor heating. It is piped. These resin pipes are generally formed of a hard resin pipe, and are protected by being inserted into the sheath pipe through the entire piping path in order to prevent damage from the outside. In many cases, a plurality of resin pipes are inserted into the sheath pipe as water pipes or drain pipes. As this type of pipe outlet forming tool, for example, a resin pipe installation tool described in JP 2007-138589 A is disclosed.

FIG. 11 shows an installation tool for the resin pipe as a pipe outlet forming tool, and the installation tool 71 of FIG. 11 is attached to an end of a sheath pipe (not shown) to connect the water pipe 61 and the drain pipe 62 to the unit bath wall. The installation tool main body 72 and the cover member 73 are provided. The installation tool main body 72 is connected to the end portion of the sheath tube via the sheath tube connection portion 74. The cover member 73 is assembled to the installation tool main body 72 so as to cover the opening, and has a cylindrical shape into which a total of three resin pipes including two water pipes 61 and one drain pipe 62 are inserted. An extending portion 75 extends forward. Further, three cylindrical insertion portions 76 through which the water passage pipe 61 and the drain pipe 62 are inserted independently are disposed on the triangular tip surface of the extending portion 75 of the cover member 73. The water pipe 61 and the drain pipe 62 inserted into the sheath pipe are guided in the drawing direction by penetrating through the insertion portion 76, and although not shown, the two water pipes 61 are drawn into the inside of the unit bath wall. Is connected to a faucet device, and the drain pipe 62 is connected to a drain pipe provided in the unit bath. Here, the inner diameters of the three insertion portions 76 are all the same, set slightly larger than the outer diameter of the water pipe 61, and larger than the outer diameter of the drain pipe 62. Since a large gap is formed between the inner peripheral surface of the insertion portion 76 through which the drain pipe 62 passes and the outer peripheral surface of the drain pipe 62, a tube holding sleeve (not shown) is press-fitted into the gap. Thereby, the water flow pipe 61 and the drain pipe 62 are prevented from moving in the radial direction in the insertion portion 76 and are installed on the unit bath wall in a stable state.
JP 2007-138589 A

  However, in the installation tool 71 described in the publication, the insertion portion 76 of the cover member 73 is formed in a cylindrical shape having a predetermined length and is slightly smaller than the outer diameter of the water pipe 61 so as to be installed in a stable state. The pipe holding sleeve is press-fitted into the gap between the inner peripheral surface and the outer peripheral surface of the drain pipe 62. For this reason, in installation on the unit bath wall, a total of three resin pipes of two water pipes 61 and one drain pipe 62 are inserted into the narrow insertion portions 76 of the cover member 73, respectively. When pulling out to the front side, a large sliding resistance is received by the frictional force generated between the outer peripheral surface of the resin tube and the inner peripheral surface of the insertion portion.

  In addition, a total of three resin tubes inserted into the sheath tube are connected to the water heater at the other end, and are generally inserted into the sheath tube in a bundled state, so that one by one from the sheath tube. It cannot be pulled out and inserted sequentially into the insertion portion of the cover member, and it is necessary to insert three at the same time. However, the outer diameter of the resin tube and the inner diameter of the insertion portion 76 of the cover member 73 are substantially the same, there is almost no gap, and all the three resin tubes drawn out of the sheath tube have substantially the same length. Since the three tip positions are substantially aligned and the insertion portions 76 are spaced apart from each other by a predetermined distance, the three resin pipes are simultaneously inserted to penetrate through the small opening of the insertion portion 76. It was very difficult to do so, and it was a laborious work. The resin tube is generally a synthetic resin tube having a considerable rigidity, and is normally packed in a wound state. Therefore, the drawing work is made more difficult.

  Therefore, the present invention has an object to provide a tube outlet forming tool that allows a plurality of resin tubes to be inserted through and pulled out easily and smoothly through these insertion holes, in which a plurality of resin tube insertion holes are provided. It is what.

  The tube outlet forming tool according to claim 1 is a cylindrical thing attached to an end of a sheath tube through which a plurality of resin tubes are inserted, and an end of the sheath tube is provided at one end side. An attachment portion to be attached is formed, and a through hole and a half hole through which the resin pipe penetrates are formed on the other end side or inside. The through hole is a hole through which a part of the plurality of resin pipes penetrates, and the same number is provided corresponding to the part of the resin pipes. Moreover, the said half hole is a hole of the half structure closed from the outer peripheral direction to the remaining resin pipes of a plurality, The same number is provided corresponding to this remaining resin pipe. Here, examples of the resin pipe include water pipes such as a water supply pipe and a hot water supply pipe, a drain pipe from a water heater, and the like. One or a plurality of the partial resin pipes and the remaining resin pipes are inserted. Of course, the number of the remaining resin pipes is the number obtained by subtracting the number of the partial resin pipes from the total number of resin pipes.

  If the said structure is further demonstrated, the said through-hole and a half hole will become the penetration hole formed in the other end side of a pipe draw-out formation tool, or the inside of a pipe draw-out formation tool. Of these, the through-hole is made to penetrate by moving the resin tube in the axial direction. On the other hand, the half hole is formed by sandwiching the resin pipe from the outer peripheral direction, that is, the direction orthogonal to the pipe axis by closing a pair of left and right semicircular holes with the center line of the circle of the opening hole as a boundary. It is to penetrate. Specifically, the half-slotted hole has a tubular tube outlet forming tool provided on its split surface as a half-slice structure, or partially provided with a semi-circular cutout hole, allowing the semi-circular lid to be opened and closed freely. For example, it is formed by attaching to In general, all the half holes corresponding to the remaining resin pipes are closed by a single closing operation. However, when the number of the remaining resin pipes is large, there are a plurality of places to be closed, or one or The closing operation may be sequentially performed in units of a plurality of half holes, and the half holes may be sequentially closed in one or more units. This is the same for the second half hole of claim 2.

  The first aspect of the invention is basically applied to one that generates a large frictional resistance when a plurality of resin pipes are simultaneously inserted through the insertion hole and pulled out. Therefore, the through hole and the half hole are generally formed to have an inner diameter that is the same as or slightly larger than the outer diameter of the resin tube, that is, substantially the same inner diameter. Specifically, for example, these insertion holes have water-stopping properties, and the periphery of the insertion hole and the outer peripheral surface of the resin tube are in contact with each other in a watertight state.

  The tube outlet forming tool configured in this way is to insert a plurality of resin pipes drawn from the end of the sheath tube through the insertion holes formed in the tube outlet forming tool. One or a plurality of resin pipes are inserted into the through hole from the pipe axis direction and the end thereof is drawn out to the opposite side of the through hole, and then the plurality of remaining resin pipes are closed from the outer peripheral direction. It is sufficient to penetrate through the half hole and pull it out. As a result, the number of the resin pipes that are inserted through the through-holes and pulled out of the pipe outlet forming tool is small, so that the sliding frictional force is much smaller than when all the resin pipes are inserted at once. Further, in the insertion operation into the half hole, it is only necessary to close the half hole from the outer peripheral direction of the resin tube, so that frictional resistance hardly occurs.

  In addition, since the number of resin pipes that first penetrate the through hole is small, the insertion operation can be performed smoothly. Further, at the time of first penetrating through the through hole, the tube outlet forming tool is held at a fixed position in the length direction by the sliding frictional force between the through hole and the outer peripheral wall of the resin tube. For this reason, when the remaining resin pipes after that are inserted through the half-slotted holes and pulled out, it is not necessary to hold the pipe pull-out outlet forming tool or the part of the resin pipes that first penetrated. What is necessary is just to concentrate on the operation | work which only closes a hole from the outer peripheral direction of a resin pipe. Therefore, it is separated into an insertion operation into the through hole and an insertion operation into the half hole, and it is not necessary to handle many resin pipes at a time, so that the operation is easy. Thereby, it is possible to smoothly insert and pull out all the resin pipes.

  As a reference, the entire tubular tube outlet forming tool is divided into two halves, with no through-holes, and a half-structured hole through which the resin pipe is inserted into the two halves. That is, by adopting a method in which the half holes are arranged in parallel as many as the number corresponding to all the resin pipes, and all the resin pipes are inserted between the half holes by simply closing the two half bodies, It is also conceivable to reduce the frictional resistance received when inserting all the resin tubes at once and inserting them through the through holes. However, as described above, when the two half-divided bodies of the pipe drawing outlet forming tool are closed once to simultaneously close the plurality of half-split holes and allow a plurality of resin tubes to penetrate the half-split holes at a time, It is necessary to close the two halves of the tube outlet forming tool while arranging the resin pipes in the corresponding half holes, so that all the resin pipes are arranged and the two halves of the tube outlet forming tool are arranged. All of the body obstruction work must be done at once. Therefore, in practice, it is difficult to work with a pipe outlet forming tool having a plurality of resin pipe halves on the split surfaces of the two halves.

  The pipe outlet forming tool according to claim 2 is formed with a first half hole and a second half hole through which the resin pipe penetrates on the other end side or inside, as compared with claim 1. The point is different. The first half hole is closed to a part of the plurality of resin tubes from the outer peripheral direction, and the second half hole is formed in the remaining resin tubes of the plurality. While being closed from the outer peripheral direction, it is closed independently from the first half hole. That is, all the holes through which the resin pipes are inserted are formed as half holes. However, the first half-split hole is formed while the remaining resin pipe is inserted into the second second half-hole after a part of the plurality of resin pipes is first inserted. Since this resin tube can be held, the same function as the through-hole of claim 1 is exhibited. Therefore, it can be said that the first half hole is a modification of the through hole of claim 1.

  The pipe outlet forming tool according to claim 3 is formed on the other end side or in the interior with the number of half holes corresponding to the number of all the resin pipes, which are separately and independently closed from the outer peripheral direction of the resin pipe. This is different from the first and second aspects.

  According to the first aspect of the present invention, the plurality of resin pipes are separated into two, and the insertion operation into the through hole and the insertion operation into the half hole are performed separately. Therefore, in the first insertion operation into the through hole, only a part of the resin pipes are penetrated, so that the frictional resistance at the time of insertion is extremely small and the operation is easy. Further, in the insertion work into the half hole, it is only necessary to close the half hole from the outer peripheral direction of the resin tube, so that frictional resistance hardly occurs and the work can be performed easily. As a result, compared with the case where all the resin pipes are inserted at once, the frictional resistance is reduced, and a plurality of resin pipes can be easily and smoothly inserted through the insertion holes and pulled out.

  According to the invention of claim 2, since the first half hole exhibits the same function as the through hole of claim 1, the same effect as that of claim 1 can be obtained. Since the first half hole has a half structure, the structure is complicated as compared with the through hole of claim 1, but the plurality of resin pipes are only closed from the outer peripheral direction. The part of the resin pipe can be inserted.

  The invention according to claim 3 has the same effect as that of claim 1 and claim 2 since the number of the half holes to be closed independently is the same as the number of resin pipes. After one resin tube is inserted into one of the half holes, the remaining resin pipes are closed in the other half by sequentially closing the other half holes while being held by the one resin tube. The holes can be sequentially inserted and pulled out.

<First embodiment>
Hereinafter, a tube outlet forming tool according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 7. In this embodiment, a total of three resin pipes, that is, a water pipe connected to the water heater via a pipe joint and two water pipes serving as return pipes and a drain pipe for draining water from the water heater, are sheath pipes. The case where it is penetrated inside and a pipe drawing outlet formation tool is attached to the edge part of this sheath pipe is shown. The first embodiment corresponds to the aspect of claim 1.

  In FIG. 6, on the bottom surface of a water heater 65 having a home cooking function, a water pipe 61 for sending hot water from the water heater 65 to a bathroom, floor heating, etc. via a pipe joint 66, and a bathroom, floor heating, etc. A water pipe 61 that is returned to make additional cooking from the hot water and a drain pipe 62 that guides drainage from the water heater to the outside are connected. These three resin tubes are inserted into a corrugated sheath tube 63 made of a synthetic resin for protecting them, and are generally accommodated in the corrugated sheath tube 63 in a bundled state using tape or the like.

Further, in each resin pipe, a protective pipe 64 such as a heat shield pipe for protecting the resin pipe and keeping the heat is attached between the pipe joint 66 and the pipe outlet forming tool 1 so as to cover the outside of the resin pipe. . Hereinafter, each component will be specifically described.

First, the water flow pipe 61 and the drain pipe 62 are made of rigid resin pipes such as a rigid cross-linked polyethylene pipe and a polybutene pipe, and fluids such as tap water, hot water and drainage flow through the inside.
Next, the corrugated sheath pipe 63 is formed of a hard resin such as polyethylene, and the outer surface is an uneven surface of a peak portion and a valley portion, has flexibility and flexibility, and is connected to the pipe joint 66. Except for the periphery of the section, it is extrapolated to the entire piping path of the water flow pipe 61 and the drain pipe 62. The corrugated sheath pipe 63 covers the outside of the water pipe 61 and the drain pipe 62 to prevent damage and damage from the outside, and also prevents deterioration due to ultraviolet rays.
The protective pipe 64 attached between the pipe joint 66 and the pipe outlet forming tool 1 is formed of a corrugated pipe made of hard resin, has flexibility and flexibility, and has a trough on the outer surface of the end. The peripheral edge 7a of the water pipe outlet hole 7 of the pipe outlet outlet forming tool 1 described later and the fitting protrusion 9b of the connecting wall 9 are fitted and engaged with these parts, so that they are connected to these parts.

  Next, as shown in FIGS. 1 to 5, the tube outlet forming tool 1 has an outer wall 2 formed in a half-cylindrical substantially cylindrical shape, and a semi-cylindrical first half 21 and a second half. By closing the half body 31, it is formed in a substantially cylindrical shape. One end side in the tube axis direction of the tube outlet forming tool 1 is provided with a sheath tube mounting portion 3 to which an end portion of the corrugated sheath tube 63 is connected, and an end portion of the corrugated sheath tube 63 is inserted therein. A sheath tube mounting hole 4 is provided. The sheath tube mounting hole 4 is formed in a substantially circular shape so as to match the cross-sectional shape of the corrugated sheath tube 63, and the inner diameter is smaller than the outer dimension of the crest on the outer surface of the corrugated sheath tube 63. It is formed larger than the outer dimension of the valley portion of the sheath tube 63, and the peripheral edge 4a is engaged with the valley portion on the outer surface of the corrugated sheath tube 63, so that the corrugated sheath tube 63 is connected in a retaining state. Yes.

  On the other hand, the other end side in the tube axis direction of the tube draw-out forming tool 1 is connected to the first draw-out wall 5 from which two water pipes 61 penetrating the inside of the tube draw-out forming tool 1 are drawn from the corrugated sheath tube 63. Similarly, a second drawing wall 6 is provided through which a drain pipe 62 penetrating the inside of the pipe drawing outlet forming tool 1 is drawn from the corrugated sheath pipe 63. The first drawer wall 5 is formed in a shape in which a part of an arc is cut out at a substantially circular chord portion. Further, the second drawer wall 6 is retreated by a predetermined distance in the tube axis direction from the first drawer wall 5 and is formed in a shape corresponding to a notched portion of the first drawer wall 5. The first drawing wall 5 is provided with two water pipe drawing holes 7 through which the water pipe 61 is drawn independently. The water pipe outlet hole 7 is formed to be smaller than the outer dimension of the crest of the outer surface of the protective pipe 64 attached to the water pipe, and larger than the outer dimension of the trough of the protective pipe 64. The protective tube 64 is connected to a state where it is prevented from coming off. The water pipe outlet hole 7 has a half structure, and the first half 21 and the second half 31 are closed around the first hinge 13 by rotating the first hinge 13 about the first half 21. The formed semicircular cutout 7b of the water pipe extraction hole 7 and the semicircular cutout 7b of the water pipe extraction hole 7 formed in the second half split body 31 are combined to form a single circular hole. .

The second drawer wall 6 is provided with one through hole 8 through which the drain pipe 62 is drawn out at the approximate center thereof. The through hole 8 has an inner diameter that is the same as or slightly larger than the outer diameter of the drain pipe 62. Thereby, the outer peripheral surface of the drain pipe 62 and the peripheral edge of the through hole 8 come into contact with each other, and water can be prevented from entering from the gap between the drain pipe 62 and the through hole 8.
A connecting wall 9 that closes the gap between the first drawing wall 5 and the second drawing wall 6 is provided at the stepped portion, and the connecting wall 9 is a protective tube 64 that covers the outside of the drain pipe 62 at the center. A circular arc recess 9a that is recessed in an arc shape is formed on the first drawing wall 5 side corresponding to the outer peripheral wall of this, and a part of the outer peripheral wall of the protective tube 64 is accommodated in the circular arc recess 9a. A pair of fitting protrusions 9b and 9b are provided on the front side of the circular arc recess 9a of the connecting wall 9, that is, the end on the first drawing wall 5 side, projecting in a direction perpendicular to the tube axis. The trough portion of the outer surface of the protective tube 64 of the drain tube 62 is engaged with the fitting protrusion 9b, and the protective tube 64 is connected to the arc recess 9a in a state of being prevented from coming off.

  Further, inside the tube outlet forming tool 1, between the sheath tube mounting portion 3 and the first drawer wall 5, the second drawer is located near the first drawer wall 5 in the tube axis direction. A partition wall 10 is formed at the same position as the wall 6. Two circular half holes 11 through which the water pipe 61 is inserted are provided in parallel in the partition wall 10 inside the pipe outlet forming tool 1. The half hole 11 is a semicircle of the half hole 11 of the first half 21 by closing the first half 21 and the second half 31 with the first hinge 13 as an axis. The notch 11a and the semicircular notch 11a of the half hole 11 of the second half 31 are combined to form one circular hole. The half hole 11 is formed to have an inner diameter that is the same as or slightly larger than the outer diameter of the water pipe 61. As a result, like the through hole 8 of the drain pipe 62, the outer peripheral surface of the water pipe 61 and the peripheral edge of the half hole 11 come into contact with each other, and water enters from the gap between the water pipe 61 and the half hole 11. Is prevented. Here, the central axis 7 c of the water pipe extraction hole 7 is disposed at a position shifted from the central axis 11 b of the half hole 11 toward the bending direction of the water pipe 61. This is because the water flow pipe 61 is gently curved and branched from the pipe outlet forming tool 1 toward the water heater 65 so that an excessive bending force is not applied to the water flow pipe 61. In this embodiment, the outer diameter of the drain pipe 62 is smaller than that of the water pipe 61, and the inner diameter of the through hole 8 is set smaller than that of the half hole 11 correspondingly. However, it is not limited to this.

  The outer wall and the connecting wall 9 between the first drawing wall 5 and the partition wall 10 are provided with a total of four drainage holes 14 penetrating into and out of the tube drawing outlet forming tool 1. The drain hole 14 is for discharging water to the outside when water leaks from the pipe joint 66 flows down the outer peripheral surface of the resin pipe into the space between the first drawing wall 5 and the partition wall 10. It is formed of small square holes, elliptical holes, round holes or the like to prevent foreign substances from entering from the outside.

  The tube outlet forming tool 1 in the present embodiment is configured by two halves, a first half 21 and a second half 31, which are divided at the split surface 12, and the first half 21 Between the first half 13 and the second half 31 is provided with a first hinge 13 formed to be thin in the tube axis direction. The first half 21 and the second half 31 are formed with the first hinge 13 as an axis. By rotating and closing relatively, a cylindrical body is formed. The tube outlet forming tool 1 can be formed by integral molding of resin in a form in which the first half 21 and the second half 31 are developed.

  In the first half 21 of the pipe outlet forming tool 1, on the split surface of the partition wall 10, as shown in FIG. 4B, the entire width of the pipe outlet forming tool 1 reaches the entire width of the water pipe 61. A rib 10a made of a small ridge that abuts along the outer peripheral surface is integrally projected. The rib 10a, together with a rib 10b of a second half-divided body, which will be described later, enhances the close contact with the outer peripheral surface of the water flow pipe 61 and enhances the waterstop. In addition, a stopper 15 is provided in the vicinity of the partition wall 10 on the inner wall surface of the first half 21 so as to abut against the tip of the corrugated sheath pipe 63 and prevent further insertion.

  Further, as shown in FIG. 3 and the like, the first half body 21 has a tube shaft on the side wall 22 opposite to the first hinge 13 so as to form a cylindrical body by closing the first hinge 13 as a shaft. A pair of left and right projections 24, 24 are integrally provided on both sides in the direction. The locked protrusion 24 is formed in an L-shaped plate shape, and the bent tip portion is locked in a locking hole 36 of a locking piece 34 of a second half body 31 described later. A first cutout hole 25 is cut out in a U-shape at two locations near the center of the hooked protrusion 24 in the tube axis direction, and one side opens to the side end face 23 of the split face 12 on the first half split body 21 side. Further, a window frame 26 slightly projecting from the surface of the outer wall 2 is integrally formed on the two peripheral edges of the first cutout hole 25.

  On the other hand, in the second half 31 of the pipe outlet forming tool 1, as shown in FIG. 4B, the rib 10a of the first half 21 is formed on the split surface of the partition wall 10, as shown in FIG. Ribs 10b made of small protrusions that are brought into contact with the outer peripheral surface of the water flow pipe 61 through the entire width of the tube outlet forming tool 1 are integrally provided. Further, on the inner wall surface of the second half 31, in the vicinity of the partition wall 10, at the position corresponding to the stopper 15 of the first half 21, the tip of the corrugated sheath pipe 63 is brought into contact with further insertion. A stopper 15 for blocking is provided.

  Further, the second half 31 of the tube outlet forming tool 1 is formed on the locking projection 24 of the first half 21 on both sides of the side wall 32 opposite to the first hinge 13 in the tube axis direction. At a corresponding position, a pair of left and right engaging pieces 34, 34 each having a rectangular plate shape are integrally projected in the horizontal direction with the joint portion with the outer wall 2 as a base end. The locking piece 34 can be rotated about a second hinge 35 provided at its base end by forming a thin wall. Each locking piece 34 is provided with a locking hole 36 formed of a square hole, and further, the tip side of the locking hole 36 is an inclined surface. A knob portion 37 for rotating is formed. Moreover, the side part of each latching piece 34 consists of a rectangular board material, and the obstruction | occlusion lid 38 which obstruct | occludes the signal wire extraction hole 16 mentioned later is integrally extended toward the center side of the pipe-axis direction. Therefore, if the locking piece 34 is rotated about the second hinge 35 and the locking hole 36 is locked to the locked projection 24 of the first half 21, the closing lid is interlocked with the rotation. 38 is configured to individually block the signal line lead-out holes 16. Further, the closing lid 38 can be folded along a breakage groove 39 provided between the locking piece 34 and a thin wall. By breaking the closing lid 38, the signal line lead hole is formed. 16 can be opened.

  Also, the outer wall 2 around the split surface 12 of the second half 31 is cut out in a U-shape at positions facing the two first notches 25 of the first half 21, respectively. A second cutout hole 40 is formed in the side facet 33 of the split surface 12. The second cutout hole 40 slightly protrudes from the surface of the outer wall 2 of the second half 31 on the two peripheral edges. A window frame 41 is integrally formed along the periphery. When the two second cutout holes 40 of the second half 31 are formed into a cylindrical body by relatively rotating and closing the first half 21 and the second half 31. The two first cutout holes 25 of the opposing first half body 21 communicate with each other, and are integrated with the first cutout hole 25 to form two rectangular holes on the split surface 12 of the tube outlet forming tool 1. A signal line lead-out hole 16 having a shape is formed. The signal line drawing hole 16 is a hole for drawing out a signal line for sending an electric signal to the hot water heater 65 or the like. Although not shown, the signal line is inserted into the corrugated sheath pipe 63 in parallel with the water pipe 61 and then drawn out from the signal line lead hole 16 and connected to the water heater 65 and the like. Furthermore, a plate-like fitting protrusion 42 is provided at the center of the side end surface 33 in the tube axis direction. The fitting protrusion 42 is formed by the first half 21 and the second half 31. Is relatively inserted into the fitted portion 27 that is the space between the pair of left and right window frames 26 of the first half 21, and the side end face 23 of the first half 21 is Positioning is performed so that the side end surface 33 of the second half 31 is in contact with the side end surface 33.

Next, a method of attaching the pipe outlet forming tool 1 configured as described above to the end portion of the corrugated sheath pipe 63 and connecting the water pipe 61 and the drain pipe 62 to the pipe joint 66 of the water heater 65. explain.
First, the two water pipes 61 and the drain pipe 62 that are inserted and returned into the corrugated sheath pipe 63 are drawn out from the end of the corrugated sheath pipe 63 by a predetermined length. At this time, since the two water pipes 61 and the one drain pipe 62 are generally bundled together by winding a tape or the like in the corrugated sheath pipe 63, these resin pipes are used. When the tape is peeled off from the corrugated sheath tube 63 by, for example, peeling off the tape at the end portion, the lengths of the three are almost the same.

  Next, with the pipe outlet forming tool 1 deployed, as shown in FIG. 7 (a), the drain pipe 62 is inserted into the through hole 8 of the pipe outlet forming tool 1 from the pipe axis direction, and the second drawer is drawn out. Pull out to the opposite side of the wall 6. Then, the tube outlet forming tool 1 is moved along the drain tube 62 to the vicinity of the corrugated sheath tube 63. At this time, although the inner diameter of the through-hole 8 is formed to be substantially the same as the outer diameter of the drain pipe 62, only one drain pipe 62 is inserted, so the pipe resistance is small and can be easily penetrated. it can. On the other hand, after allowing the drain pipe 62 to penetrate the through-hole 8 of the pipe outlet forming tool 1, the pipe outlet forming tool 1 can be separated from the peripheral corner of the through-hole 8 even if the holding by hand is released. The drain pipe 62 is held at a predetermined position and temporarily fixed by a hook with the outer peripheral surface of the drain pipe 62 and a frictional force with the drain pipe 62. Subsequently, the protective tube 64 is externally fitted to the drain tube 62 as shown in FIG. For this purpose, before the drain pipe 62 is inserted into the through hole 8 of the tube outlet forming tool 1, the drain pipe 62 is disposed in the arc recess 9 a of the connecting wall 9, and in this state, the drain pipe 62 together with the through hole 8 is a protective pipe 64. Insert it inside. Alternatively, after the drain pipe 62 is inserted into the through hole 8, the protective pipe 64 is externally fitted into the drain pipe 62 and pushed along the drain pipe 62, so that the distal end is fitted into the arc recess 9 a of the connecting wall 9. The mating protrusion 9b is forcibly moved over and is attached and accommodated in the circular arc recess 9a.

  Next, the protective pipe 64 is fitted on each of the two water pipes 61 drawn from the corrugated sheath pipe 63. Then, with the tube outlet forming tool 1 held by the drain pipe 62, the corrugated sheath pipe 63 is connected to the first half 21 or the second half as shown by a two-dot chain line in FIG. It arrange | positions in the peripheral edge 4a of the sheath pipe attachment hole 4 of the body 31, and the peripheral edge 4a is latched to the trough part of the outer peripheral wall of the corrugated sheath pipe 63. Further, as shown in FIGS. 4B and 7B, the water pipe 61 is arranged on the semicircular notch 11 a of the half hole 11 of the first half 21 or the second half 31. And although not shown in figure, the front-end | tip of the protection pipe 64 fitted on the water pipe 61 is arrange | positioned on the semicircle notch 7b of the water pipe extraction hole 7 of the 1st half body 21 or the 2nd half body 31, and the periphery Is locked to the valley of the outer peripheral wall of the protective tube 64. Subsequently, the first half 21 is rotated about the first hinge 13, and the fitting protrusion 42 at the center of the second half 31 is fitted to the fitted portion 27 at the center. While positioning, the side end face 23 of the first half 21 and the side end face 33 of the second half 31 which are the split faces 12 are brought into contact with each other and closed, as shown in FIG. When both halves are closed, as shown in FIG. 2, the pair of left and right engaging pieces 34, 34 of the second half 31 are rotated about the second hinge 35, respectively, so that a pair of engaging holes 36 are provided. , 36 are respectively locked to the pair of locked projections 24, 24 of the first half 21. Thereby, the corrugated sheath pipe 63 is connected to the sheath pipe mounting portion 3 of the pipe outlet forming tool 1 in a retaining state. Further, the protective pipe 64 is connected to the water pipe drawing hole 7 of the first drawing wall 5 of the pipe drawing outlet forming tool 1 in a retaining state. The half hole 11 of the partition wall 10 of the tube outlet forming tool 1 is in contact with the outer peripheral surface of the water conduit 61. As described above, the tube draw-out forming tool 1 is attached to the end portion of the corrugated sheath tube with three resin pipes penetrating therethrough, and the attaching operation of the tube draw-out forming tool 1 is completed.

  When attachment of the pipe outlet forming tool 1 to the end of the corrugated sheath pipe 63 is completed, the protective pipe 64 is compressed in the pipe axis direction to expose the ends of the water pipe 61 and the drain pipe 62 by the amount of connection. Alternatively, by using a protective pipe 64 shorter than the drawing length of the water pipe 61, the water pipe 61 is exposed by the connection allowance, and the water pipe 61 and the drain pipe 62 are connected to the bottom surface of the water heater 65 using a tool. The joint 66 is externally fitted and press-fitted into a connection cylinder (not shown). Then, the ends of the water pipe 61 and the drain pipe 62 are connected to the pipe joint 66 of the water heater 65 by, for example, further fitting and tightening a fastening ring 66a on the outside of these resin pipes. Thereafter, the end portion of the protective tube 64 is pushed back to the pipe joint 66 side. By the above, the connection of the water flow pipe 61 and the drain pipe 62 with respect to the pipe joint 66 of the water heater 65 is completed.

Next, the operation of the tube outlet forming tool 1 will be described.
The tube draw-out forming tool 1 is used to insert a plurality of resin pipes drawn from the end of the corrugated sheath pipe 63 into the inside when attaching to the end of the corrugated sheath pipe 63. In the deployed state of the tool 1, first, one drain pipe 62 is inserted into the through hole 8 of the second drawing wall 6 from the tube axis direction and the end thereof is pulled out to the opposite side of the through hole 8. Are arranged on the semicircular notch 11a of the half hole 11 of the first half 21 or the second half 31 from the side of the pipe outlet forming tool 1, and the first half 21 and What is necessary is just to penetrate the half hole 11 by closing the 2nd half body 31, and pull it out. As a result, only one drain pipe 62 passes through the through-hole 8 from the pipe axis direction, so that the pipe through which the three resin pipes are inserted is inserted as compared with the case where three resin pipes are penetrated in the pipe axis direction at once. The resistance is much smaller. Further, in the insertion work into the half hole 11, it is only necessary to close the first half body 21 and the second half body 31 and close the half hole 11 from the outer peripheral direction of the water pipe 61. Is hardly received. Therefore, since the overall pipe resistance that is received during insertion into the tube draw-out forming tool 1 is very small, all the resin pipes can be easily inserted into the tube draw-out forming tool 1.

  In addition, when the drain pipe 62 is first passed through the through-hole 8, the pipe outlet / outlet forming tool 1 is caught between the peripheral corner portion of the through-hole 8 and the outer peripheral surface of the drain pipe 62 or the through-hole 8 and the drain. The drain pipe 62 is held at a certain position in the length direction by the sliding frictional force with the pipe 62. For this reason, when the following two water pipes 61 are inserted through the half hole 11 and pulled out, it is not necessary to hold the pipe outlet / former 1 and the drain pipe 62, but simply the first half body. What is necessary is just to concentrate on the operation | work which only closes 21 and the 2nd half body 31, and closes the half hole 11 from the outer peripheral direction of the water pipe 61. Therefore, the work of inserting the drain pipe 62 into the through hole 8 and the work of inserting the two water pipes 61 into the half hole 11 are separated, and it is not necessary to operate many resin pipes at once. Easy to work with. Thereby, as a whole, the resin tube can be smoothly inserted and pulled out.

<Second embodiment>
Next, the tube outlet formation tool of 2nd embodiment of this invention is demonstrated based on FIG. This second embodiment corresponds to the aspect of claim 2. 8 and subsequent FIGS. 9 and 10 schematically show a state in which a plurality of resin tubes are inserted through the tube outlet forming tool 1 in plan view.
In FIG. 8, the tube outlet forming tool 1A is formed in a substantially cylindrical shape, and is divided into a first half 21, a second half 31, and a third half 51 in the tube axis direction. Yes. The entire side surface of the drawing side of the resin pipe, which is the other end side of the pipe drawing port forming tool 1, is formed by a single drawing wall 52. One split surface 53 in the drawer wall 52 is formed with one half hole 11 at the center, and the other split surface 54 in the drawer wall 52 is formed with a pair of left and right half holes 11, 11. ing. The upper first half 21 in FIG. 8A can be rotated in the vertical direction in FIG. 8 with respect to the central second half 31 with the hinge 55 as an axis. The half body 51 can be rotated in the vertical direction around the hinge 56 with respect to the second half body 31. FIG. 8B shows a state in which the first half 21 and the third half 51 are expanded with respect to the second half 31. In the second embodiment, for convenience of explanation, it is assumed that the protective tube 64 that protects the drawn resin tube is not attached. However, when the protective tube 64 is externally fitted to the resin tube, as in the first embodiment, the partition 10 is formed inside the tube outlet forming tool 1, and the half hole 11 is provided in the partition 10, and the tube What is necessary is just to provide the water-flow pipe extraction hole 7 in the extraction wall formed in the other end side of the extraction port formation tool 1. FIG.

  A drain pipe 62 is inserted into one half hole 11 between the upper first half body 21 and the center second half body 31 in FIG. 8A, and the inner diameter is outside the drain pipe 62. It is formed in the same size as the diameter. Further, in each of the pair of half holes 11, 11 between the second half 31 at the center and the third half 51 at the lower part of FIG. 8 (a), the water pipe 61 is inserted. The inner diameter is substantially the same as the outer diameter of the water pipe 61. One upper half hole 11 is formed to have an inner diameter smaller than the pair of lower half holes 11, 11 corresponding to the outer diameter of the drain pipe 62. However, the resin pipes inserted into the respective half holes 11 are not limited to the above combinations, and the inner diameters of the respective half holes 11 are appropriately set correspondingly. The upper half hole 11 corresponds to the first half hole of claim 2, and the lower pair of half holes 11, 11 corresponds to the second half hole.

In other words, the upper half hole 11 is a structure in which the through hole 8 of the first embodiment has a half structure through the hinge 55, and the second embodiment is the first in this respect. This is different from the first embodiment.
In order to allow the resin pipe to be inserted in the tube outlet forming tool 1 of the second embodiment, first, on the semicircular notch 11a at the center of the split surface 53 of the second half-divided body 31 in the expanded state of FIG. After the drain pipe 62 is arranged, the hinge 55 is pivoted about the shaft to close the first half body 21, thereby closing the upper half hole 11 and inserting the drain pipe 62. In this state, similarly to the through hole 8 of the first embodiment, the tube outlet forming tool 1 is held by the drain tube 62 at an arbitrary position. Therefore, when inserting the two water flow pipes 61 after that, it is not necessary to hold | maintain the pipe outlet formation tool 1 and the drain pipe 62. FIG. After that, similarly to the first embodiment, the water pipes 61 are respectively disposed on the pair of semicircular cutouts 11a and 11a of the split surface 54 of the second half-divided body 31, and are rotated about the hinge 56 as an axis. Close the half halved body 51. As a result, the pair of lower halves 11 and 11 are closed at the same time, and the two water pipes 61 are inserted through the drawer wall 52 at the same time.

  Therefore, the tube outlet forming tool 1 according to the second embodiment operates in the same manner as the first embodiment because the through hole 8 according to the first embodiment is merely replaced with the half hole 11. Since the half hole 11 has a half structure, the structure is complicated compared to the through hole 8 of claim 1, but the drain pipe 62 is arranged in the first half after the water pipe 61 is arranged. By simply closing the split body 21 and closing the half hole 11 from the outer peripheral direction of the drain pipe 62, the half hole 11 can be inserted.

<Third embodiment>
Next, the tube outlet formation tool of 3rd embodiment of this invention is demonstrated based on FIG. This third embodiment corresponds to the aspect of claim 3.

Similarly, the lower left third half 51 is rotated up and down with respect to the first half 21 with the hinge 55 as an axis. The lower right fourth half 57 is configured to be pivotable with respect to the first half 21 about the hinge 59 in the vertical direction. Therefore, each half hole 11 is closed separately from each other by closing each half body, and is different from the first embodiment and the second embodiment in that respect. In the third embodiment as well, for convenience of explanation, the protective tube 64 that protects the drawn resin tube is not attached. However, of course, the protective tube 64 may be attached.

  In order to insert three resin tubes into the tube outlet forming tool 1, first, a drain is formed on any one of the semicircular cutouts of the split surface 53 of the first half 21 and the second half 31. After the pipe 62 is arranged, the second half-divided body 31 is closed by rotating around the hinge 54 to close the half-hole 11 and allow the drain pipe 62 to be inserted. In this state, similarly to the through hole 8 of the first embodiment, the tube outlet forming tool 1 is held by the drain tube 62 at an arbitrary position. Therefore, when inserting the two water flow pipes 61 after that, it is not necessary to hold | maintain the pipe outlet formation tool 1 and the drain pipe 62. FIG. Next, for example, the first water pipe 61 is disposed on the semicircular cutout of the split surface 54 between the first half 21 and the third half 51, and the third water pipe 61 is rotated around the hinge 55 as the third half. The half body 51 is closed. Thereby, the lower left half-split hole 11 is closed at the same time, and the first water pipe 61 is inserted into the drawer wall 52 at the same time. Next, the second water pipe 61 is arranged on the semicircular cutout of the split surface 58 of the first half 21 and the fourth half 57, and the fourth half is rotated by pivoting around the hinge 59. Close body 57. As a result, the lower right half-split hole 11 is simultaneously closed, and the second water pipe 61 is simultaneously inserted into the drawer wall 52.

As described above, the pipe outlet forming tool 1 according to the third embodiment has the same effects as those of the first and second aspects because each of the half holes 11 is independently closed. After the other drain pipe 62 is inserted into the half hole 11, the other two half pipes 61 are sequentially closed while being held in the drain pipe 62, so that the remaining two water pipes 61 are separated from the other half pipes 11. The holes 11 can be sequentially inserted and pulled out.
In addition, the resin tube inserted in each half hole 11 is not restricted to the above-mentioned combination, and the inner diameter of each half hole 11 is also set accordingly.
