The restriction portion 11b secures a wiring space in which a signal line can be routed between the end face of the sheath pipe and the blocking wall 12.

  The pipe outlet 13 is formed to have substantially the same diameter as the outer diameter of the drawn hot water pipe, and further, a pressure contact rib 14 is provided on the inner surface thereof along the circumferential direction, and the water supply from which the pressure contact rib 14 is drawn is provided. The gap between the hot water supply pipe and the pipe outlet 13 is closed by pressing against the outer surface of the hot water pipe. In addition, the same press-contact rib 14 is provided also in the end surface of the obstruction | occlusion wall 12 which faces when each division body (20, 30) is assembled | attached, and the gap between obstruction | occlusion walls is obstruct | occluded.

  The protective tube connecting portion 15 is fitted into a step portion formed on the outer surface of the protective tube moved in the axial direction from the end portion of the drawn-out hot water pipe, with the hot water pipe inserted through the inside. A connecting port 15a that can be connected in a state in which the protective tube is prevented from moving in the axial direction is provided. Further, between the connecting port 15a and the closed wall 12 forming the pipe drawing port 13 (specifically, a position close to the closed wall 12), a connecting portion with a heat source device to which a hot water supply pipe is connected. A discharge port 15b is formed to discharge the hot water that has leaked and traveled along the outer surface of the hot water supply pipe to the outside.

  The closing portion 21 is provided with a square hole-shaped locking portion 21 a that is locked to the locked portion 31 provided on the other divided body 30, and the locking portion 21 a is engaged with the locked portion 31. By stopping, both divided bodies (20, 30) can be assembled. Further, the end of the closing portion 21 is bent in a direction away from the outer surface of the other divided body 30 in the assembled state, and the locking state of the closing portion 21 in which the locking portion 21 a is locked to the locked portion 31. A finger hook portion 21b for forcibly canceling is formed. Then, a lid that extends from the outside of the signal line lead-out port 50, which will be described later, is extended to the side of the closed part 21 (specifically, the direction in which the closed parts 21 face each other). A body 22 is formed. The lid body 22 has a base end portion 22a formed to be thin and is provided so as to be rotatable with respect to the closing portion 21. The lid portion 22 is in a state where both the divided bodies are assembled by locking the closing portion 21. In addition, only the lid 22 can be rotated to allow the signal line outlet 50 to face outward.

  Between the closed portions 21 of the joint portion 42, one divided body 20 is provided with a protruding portion 23 that protrudes, and the other divided body 30 is assembled with both divided bodies. In order to prevent axial displacement, an abutting step portion 33 that abuts on both axial sides of the protruding portion 23 is provided. Furthermore, a substantially L-shaped convex portion 43 provided continuously from the projecting portion 23 and the contact step portion 33 is provided on both divided bodies (20, 30), and the closed portion in a state where both divided bodies are assembled. The lid body 22 is arranged on the inner side of the U-shape surrounded by the convex portion 43. More specifically, the convex portion 43 (the U-shaped inner surface surrounded by the convex portion 43) and the side edge surface of the lid body 22 are provided so as to substantially contact each other. Even if the lid body 22 is slightly tilted in the opening direction until the lid body 22 tilts in the opening direction beyond the protruding height, the signal wire drawing port 50 cooperates with the lid body 22 and the convex portion 43. Is substantially blocked so as not to face the outside.

  A signal line lead-out port 50 is formed inside the U-shape surrounded by the convex portion 43 to draw out a signal line wired in the sheath pipe together with the hot water pipe. The signal line lead-out port 50 is opened in both the divided bodies (20, 30) on the side of the joint portion 42 and is cut out in a U-shape that communicates with the joint portion 42, and the both divided bodies are assembled. Therefore, one signal line lead-out port 50 is formed by matching each other. The signal line lead-out port 50 is provided with a tongue piece 51 extending from the inner peripheral surface of the signal line lead-out port 50 toward the inside of the signal line lead-out port so as to block the entire signal line lead-out port 50. Yes.

  A plurality of the tongue pieces 51 are provided independently of each other by the notches 51a. Specifically, the two tongue pieces 51 are opposed to the signal line outlet 50 provided in one divided body so that the two tongue pieces 51 communicate with the joint portion 42 therebetween (so that the notch 51a communicates with the joint portion 42). The signal line outlet 50, which is provided by assembling both divided bodies (20, 30), is separated into a cross shape between the two tongue pieces 51 and the joint portion 42, for a total of four. The entire tongue of the signal line 50 is closed by the two tongue pieces 51. The tongue piece 51 is formed in a thin plate shape and has flexibility so as to be freely bent. By contacting the outer surface of the signal line drawn from the signal line drawing port 50, the tongue piece 51 can Bending outwards and allowing signal lines to be pulled out. The tongue 51 bent and deformed by the signal line is bent following the signal line drawing and is in contact with the outer surface of the signal line. The gap generated between the signal line outlet 50 is reduced. Therefore, the air flow from the gap generated between the signal line and the signal line outlet 50 can be reduced, and the temperature drop of the hot water pipe piped in the sheath pipe can be suppressed. In addition, the space between the adjacent tongue pieces 51 (the cut 51a) is formed in a substantially V-shaped narrow width that can be temporarily held by pushing the signal line therebetween.

  The tongue piece 51 is further provided with flexibility to allow movement of the drawn signal line C in the axial direction. Therefore, even when the signal line C is pulled out from the closed drawer opening forming tool so as to move in the axial direction, the signal line is damaged even if the outer surface of the signal line and the tongue piece 51 are slid. There is no. Further, when the hot water pipes piped together in the sheath pipe are thermally expanded and contracted, and the signal line moves in the axial direction so as to be pulled by the hot water pipe, the tongue 51 and the outer surface of the signal line are in sliding contact with each other. On the other hand, the movement of the signal line in the axial direction can be allowed without the end face of the tongue piece 51 damaging the outer surface of the signal line.

  Next, the installation method of the hot water supply pipe drawer port forming tool 10 in the first embodiment will be described mainly with reference to FIGS. It has the flexibility piped in the said Saya pipe R from the edge part of the synthetic resin Saya pipe R which has the corrugated flexibility in which the unevenness | corrugation was formed in the outer surface piped to the vicinity of the heat source machine B A water supply hot water pipe P such as a cross-linked polyethylene pipe and a signal line C wired in the sheath pipe R together with the water hot water pipe P are drawn out for a predetermined length, and the drawn water supply hot water pipe P is moved from its end. It is inserted into the tube S and the end is connected to the connection B1 of the heat source device B. Then, as shown in FIG. 5, the split body 20 on one side of the draw-out port forming tool 10 in an opened state after the assembly of the hot-water supply pipe draw-out port forming tool 10 is released is applied to the end of the sheath pipe. The engaging protrusion 11a is engaged with the step R1 on the outer surface of the pipe R. At that time, the end surface of the Saya tube R is arranged away from the closed portion so as to secure a space in which the signal line C can be wired between the end surface of the Saya tube R and the closed portion with the restricting portion 11b as a guide. Further, the hot water pipe P inserted in the protective pipe S is moved in the radial direction together with the protective pipe S, and the connecting port 15a is fitted in the step portion S1 formed on the outer surface of the protective pipe S, so that the hot water pipe P is applied to the pipe outlet 13 on one side. In FIG. 5, signal lines are omitted from the drawing.

  Then, by pushing the signal line C drawn out from the end portion of the sheath tube so as to move the signal line C in the radial direction between the adjacent tongue pieces 51 in the tongue piece 51, the side surface of the adjacent tongue piece 51. Temporarily held between (side edges forming a temporary holding space). At this time, when the signal line C is pushed in, both adjacent tongue pieces 51 are bent and deformed, and the side surfaces of the tongue pieces 51 abut against the outer surface of the signal line C. Further, most of the pushed signal line C in the cross section is disposed between the tongue pieces 51 and the remaining part protrudes from the joint portion 42.

  From this state, the other-side divided body 30 is pivoted about the hinge 41 to close so that the joining portion 42 is matched, so that the engaging projection 11a of the other-side divided body 30 is connected to the Saya tube R. While engaging with the outer surface, the connecting port 15a of the protective tube is fitted into a step S1 formed on the outer surface of the protective tube S, and the sheath tube R and the protective tube S and the drawer opening forming tool 10 are integrally connected. The And the hot water supply pipe P addressed in the pipe drawing-out port 13 has the said press-contact rib 14 press-contacted over the whole outer surface circumferential direction by closing both division bodies (20, 30), and a substantially watertight state. In addition, the pressing ribs 14 are in pressure contact with each other at the end faces of the blocking wall 12 facing each other to form a substantially watertight state. In this state, the projecting portion 23 substantially abuts on both sides of the abutting step portion 33, thereby restricting the axial displacement of both divided bodies.

  The signal line C temporarily held in the signal line drawing port 50 of the one divided body 20 is connected to the signal line drawing port 50 of the other divided body 30 when the signal line drawing port 50 of the other divided body 30 comes close. 50 enters between a plurality of tongue pieces 51 in 50. Along with this, the tongue piece 51 on the other split body 30 side bends and deforms along the outer shape of the cable. The signal line C and the signal line lead-out port 50 are formed in a state where one signal line lead-out port 50 is formed by matching the joint portions 42 of the signal line lead-out ports 50 of both divided bodies (20, 30). The tongue pieces 51 of both divided bodies are positioned in a state where they are bent around the entire circumference of the signal line C so as to close the gap.

  In order to assemble the drawer opening forming tool 10 in which both the divided bodies are closed so as not to open, the closing portion 21 is rotated about the base end so that the locking portion 21a of the closing portion 21 is engaged with the engaged portion. Lock to the stop 31. At this time, the lid 22 corresponding to the signal line outlet 50 from which the signal line C is drawn out of the two closed portions 21 is in contact with the outer surface of the signal line C and is opened outward with the base end as an axis. It becomes. In addition, after plastically deforming so as to be in an open state (with a bend), the closing portion 21 is rotated so that the locking portion 21a is locked to the locked portion 31 so that both divided bodies are obtained. (20, 30) may be assembled.

  According to the hot water supply pipe drawing port forming tool of the first embodiment, the tongue piece 51 covers the gap between the inner surface and the signal line C in the signal line drawing port 50 from which the signal line C is drawn. Thus, since the gap is reduced, air circulation can be reduced. In particular, the tongue piece 51 is flexible so as to follow its outer shape, and can flexibly cope with signal lines having different outer shapes. Further, due to the flexibility of the tongue piece 51, the tongue piece 51 in contact with the signal line C does not bite into the signal line when the two divided bodies are closed, and the signal line is not immediately bent and damaged. Furthermore, even if the signal line tries to move along with the thermal expansion and contraction of the hot water supply pipe P, the soft movement allows the signal line to move in the axial direction due to the accompanying movement.

  Further, by installing as shown in FIG. 10, the lid body 22 serves as an “umbrella”, and rain water can be prevented from entering between the tongue pieces 51. However, when the Saya tube R is piped from above and attached to the end of the Saya tube R so that the tube extraction port 13 of the extraction port forming tool faces downward, the lid 22 is connected to the tube extraction port side ( By selecting the signal line lead-out port side extending toward the lower side and pulling out the signal line C, the lid 22 can function as a role of “umbrella”.

  Since the signal line lead-out port 50 is provided in communication with the joint portion 42 of the divided body, it is not necessary to insert the signal line C into the through hole so as to push it in the axial direction from the end portion, and the workability is good. Moreover, the operation | movement which closes a division body and the operation | movement which guides a signal wire | line to the signal wire outlet 50 can also be performed by a series of operation | movement.

In the above-described first embodiment in which one signal line lead-out port 50 is formed in the assembled state (closed state), when one of the divided bodies 20 and the other divided body 30 is opened, the divided body is opened. A signal line outlet 50 is formed in each. Therefore, even if the one or the other one of the divided body as was held against the sheath tube R, Ru can be temporarily held signal line C to the signal line outlet 50 of one or the other of the divided body of held against the split side Therefore, either divided body may be applied to the sheath tube R. Further, the signal line C can be temporarily held in the divided body that is not applied to the sheath tube R. And by making it hold temporarily, a possibility that a signal wire may be pinched | interposed between junction parts when closing both division bodies is reduced.

  The lid 22 that closes substantially the entire signal line outlet 50 from the outside can reduce the air flow even in a place where the signal line outlet 50 is not used, and even at the end of the sheath pipe where the signal line is not wired. A hot water pipe outlet can be formed, and members can be shared.

  Since the lid 22 for closing the signal line outlet 50 is integrally provided in the closing portion 21 to which the divided body is assembled, if the closing portion 21 is rotated and assembled, it is interlocked with the rotation of the closing portion 21. The lid 22 can block the signal line outlet 50.

  Note that the signal line outlet 50 of the first embodiment is provided in each of the two divided bodies, and they are matched to form one signal line outlet 50. However, the signal line outlet 50 is provided only in one or the other divided body. A drawer port 50 may be formed.

  Specifically, as shown in FIG. 11 to FIG. 13, the signal line outlet 50 is formed only on one side of the divided body, and substantially the entire signal line outlet 50 is closed by the four tongue pieces 51, A cross-shaped cut 51a partially communicating with the joint 42 is formed, and when the two divided bodies are closed, a part of the cut 51a communicated with the cross-shaped joint 42 is formed on the other divided body. The joint portion 42 will be closed.

  In this case, by pushing the signal line C from the joint portion 42 to the center of the cross-shaped cut 51a, the entire signal line C can be completely temporarily held in the signal line outlet 50 in advance.

  Next, a second embodiment of the present invention will be described with reference to FIGS. The hot water supply pipe outlet forming tool according to the second embodiment is made of synthetic resin and has a tubular shape as a whole, but is different from the first embodiment in that it is not configured as a divided body.

  On one end side, there is an engagement protrusion 11a that engages with the outer surface of the Saya tube, and a Saya tube that can be attached to the Saya tube by being externally fitted to the Saya tube end so that the Saya tube end is inserted. A pipe attaching part 11 is provided, and at the other end, two pipe outlets 13 from which the hot water pipe drawn from the Saya pipe end is drawn out and a signal line drawn from the Saya pipe end are drawn out. A closed wall 12 is provided which forms a single signal line outlet 50 and closes the other.

  The tube drawing port 13 and the signal line drawing port 50 have a cylindrical shape erected from the closed wall 12, and the tube drawing port 13 is formed to have substantially the same diameter as the outer surface of the drawn tube, and the inner surface of the tube drawing port. And the outer surface of the hot water supply pipe closely contact each other to form a substantially watertight state. In addition, a pair of tongue pieces 51 which are provided by integral molding and block a part of the signal line drawing port 50 are provided at the signal line drawing port 50 so as to face each other.

  The tongue 51 has flexibility, and a part of the tongue 51 is connected to the signal line outlet 50 and the remaining part is separated from the signal line outlet 50. The tongue piece 51 that closes the portion is composed of two tongue pieces 51. The hot water supply pipe drawing port forming tool 10 is not provided with a lid for closing the signal line drawing port 50. Further, the hot water supply pipe and the signal line are inserted into the inside of the drawing port forming tool from the side of the sheath pipe attaching portion 11 and pulled out while being pushed into the respective drawing ports (13, 50) from the end portions.

  FIG. 16 shows a state in which the signal line C is drawn out from the signal line lead-out port 50. FIG. 16 is a main part enlarged view and a main part enlarged sectional view showing a state in which the circular signal line C is drawn out.

  As shown in FIG. 16, when the circular signal line C is pulled out, both tongue pieces 51 are slightly bent as compared with the original shape, and a part of the outer surface of the signal line C is connected to the inner surface of the signal line outlet 50. The tongue 51 is in contact with the remaining portion, and the gap between the signal line C and the signal line lead-out port 50 is closed over the entire circumference of the signal line C. Further, when the signal line C having an outer shape larger than that of the illustrated signal line C is pulled out, both the tongue pieces 51 are bent larger than the original shape.

  According to the hot water supply pipe drawing port forming tool of the second embodiment, the signal line drawing port 50 from which the signal line C is drawn is provided with the tongue piece 51 that covers the gap between the inner surface and the signal line C. The tongue piece 51 or the tongue piece 51 and the inner surface of the signal line outlet 50 cooperate to reduce the gap, so that air circulation can be reduced and the tongue Since the piece 51 has the flexibility to bend so as to follow its outer shape, it can flexibly cope with signal lines C having different outer shapes.

  In addition, only the part of the Saya pipe attachment part 11 of the said 2nd Embodiment is comprised by the division | segmentation body which can be assembled | attached, and it is good also as a cylindrical Saya pipe attachment part. In this case, it is made to fit in a Saya pipe by attaching both divisions after applying to a Saya pipe.

  Further, the tubular shape of the tube drawing port 13 and the signal line drawing port 50 may be constituted by a split body that can be assembled, and the tube drawing port 13 and the signal line drawing port 50 that are formed into a tubular shape by assembling may be configured. good. In this case, friction with the inner surface of each outlet when the hot water supply pipe and the signal line are pulled out is reduced, and the drawing work can be performed easily.

  Next, another embodiment of the signal line outlet 50 in the present invention is shown in FIG. FIG. 17 shows only the main part of the signal line C lead-out port in an enlarged manner. FIG. 17A shows an example in which a large number of notches 51a of the tongue piece 51 are formed and a plurality of tongue pieces 50 (eight in the drawing) are formed. In FIG. 17B, the cuts 51a are formed radially and each tongue piece 51 is formed in a substantially fan shape or a substantially triangular shape.

  In addition, the tongue piece 51 provided in the signal line lead-out port 50 of each embodiment is bent and deformed corresponding to a plurality of types of signal lines C having different diameters and outer shapes, but in the case of the minimum signal line C Alternatively, the gap between the outer surface of the signal line C and the inner surface of the signal line lead-out port 50 may be closed without being deformed. Further, even when a plurality of signal lines C are pulled out at a time, the diameter and the outer shape are different from those of one signal line C. Even in such a case, the gap can be reduced by the tongue piece 51. .

  According to each of the above embodiments, since the tongue piece 51 that closes part or all of the signal line outlet 50 is provided by integral molding, the tongue piece 51 can be molded by injection molding using a single material of synthetic resin. In addition, there is no need to prepare a member for closing the gap between the signal line outlet 50 and the signal line C, and the tongue piece 51 is not removed from the signal line outlet 50 during the drawing operation. Furthermore, since the tongue piece 51 is formed in a thin plate shape that is thinner than other portions, the flexibility of following the signal line C is provided. As a result, the signal line outlet port 50 and the signal are deformed while corresponding to the signal line C having a different diameter and outer shape while ensuring the strength of other parts such as the Saya tube R connecting portion and the pipe outlet port 13. The gap generated between the line C and the line C can be reduced.
