  The best embodiment of the through piping tool in the present invention will be described below. As shown in FIG. 5, the through-pipe 1 according to the present invention is formed in the structure 2, and the opening 31 is inserted through the substantially circular through-hole 3 and the inner peripheral surface 32 of the through-hole 3. 3 and the outer peripheral surface 42 in which the screw groove 41 is formed, as shown in FIG. 3, a substantially cylindrical tube member 4 filled with the filler 5 and a tube inserted through the through hole 3. From one side of the member 4, the one side lid member 6 a that is screwed into the pipe member 4 and covers the opening 31 on one side of the through hole 3, and from the other side of the pipe member 4 that is inserted through the through hole 3. The other side lid member 6b that is screwed into the tube member 4 and covers the opening 31 on the other side of the through hole 3, the one side lid member 6a, and the at least one through hole of the other side lid member 6b. A projection 7 formed on the side surfaces 61 a and 61 b of the opening 3 and guiding the pipe member 4 to the center of the opening 31 of the through-hole 3. It is equipped with.

  Examples of the structure 2 include an outer wall of a house and a partition wall inside the house. However, the structure 2 is not limited thereto, and can be used for a floor board, furniture, a door, and the like. Moreover, the material of the structure 2 can also be used for various materials such as concrete, woody material, gypsum board, and ceramics material, and these are not particularly limited. The through holes 3 are formed so that the openings 31 on both sides thereof are substantially circular as shown in FIG. 5, and the thickness of the structure 2 is increased in the thickness direction of the structure 2. It is formed so as to penetrate, and the shape thereof is substantially cylindrical. Further, as described above, the through-hole 3 does not have a substantially cylindrical shape, for example, as shown in FIG. 6, the through-hole 3 has substantially circular openings 31 on both sides thereof. It can also be used for a structure 2 or the like configured by combining two sheets. Moreover, the diameter of the opening part 31 of the through-hole 3 should just be formed larger than the diameter of the opening part 43 of the pipe member 4 inserted in this through-hole 3.

  As shown in FIG. 1, the tube member 4 is formed in a substantially cylindrical shape, and a screw groove 41 is formed on the outer peripheral surface 42 thereof. And in this embodiment, although the screw groove 41 is formed over the whole outer peripheral surface 42 of the tube member 4, the screw groove 41 may be formed in only one part, and it changes suitably. Can do. In addition, it is preferable that at least a portion inserted through the through-hole 3 is formed in a substantially straight shape, and the shape of the other portions is a substantially straight shape as in the above-described portions. It may also be bent. Furthermore, the pipe member 4 may be connected to other pipe members 10 via joints 9 at both ends as shown in FIG. The pipe member 4 can be made of a low-cost and versatile synthetic resin such as vinyl chloride or polypropylene as its material, and can be suitably used. Even if the pipe member 4 is hard, Moreover, it may have flexibility.

  However, the pipe member 4 may use a metal material, and the material can be appropriately selected according to the intended use. And, inside the pipe member 4, an electric wire used for a power source, an optical cable used for a home network, a wiring such as a LAN cable, a liquid material such as drainage and tap water, and a tubular member are passed. It is possible. Moreover, as shown in FIG. 17, the flat part 43 in which the screw groove 41 is not formed in the edge part of this pipe member 4 may be provided so that it may oppose. By doing so, when both or one of the one-side lid member 6a and the other-side lid member 6b is fastened to the opening 31 side of the through hole 3, the flat surface portion 43 is clamped by a clamping tool 11 such as a pliers or a monkey wrench. By clamping, both or one of the one side lid member 6a and the other side lid member 6b can be fastened to the opening 31 side of the through hole 3 without rotating the tube member 4. In this way, the work can be performed from one side of the structure 2.

  And between the inner peripheral surface 32 of the through-hole 3, and the outer peripheral surface 42 of the pipe member 4 in which the screw groove 41 was formed, the filler 5 is filled as shown in FIG. Further, as the filler 5, for example, a silicon-based caulking material is preferably used, but the space between the inner peripheral surface 32 of the through hole 3 and the outer peripheral surface 42 of the tube member 4 can be reliably sealed. If it is a thing, it will not be limited to these, The well-known filler 5 can be used suitably. And the place where the filler 5 is filled is, for example, as shown in FIG. 3, between the inner peripheral surface 32 of the through hole 3 and the outer peripheral surface 42 of the pipe member 4 in the thickness direction of the through hole 3. It is preferable that the entire section is filled with the filler 5. However, as shown in FIG. 4, when the through-hole 3 is long in the thickness direction, the filler 5 is filled from the opening 31 of the through-hole 3 to the inside by several centimeters. Thus, airtightness and watertightness can be ensured. Furthermore, as shown in FIG. 6, when the structure 2 is composed of two wall bodies 8, the filler 5 is filled in the vicinity of the opening 31 of the through hole 3 formed in each wall body 8. You just have to be done.

  As shown in FIG. 3, the center ring 12 is externally fitted to the outer peripheral surface 42 of the tube member 4 inside the through hole 3 and between the one side lid member 6a and the other side lid member 6b. . The diameter of the center ring 12 is preferably substantially the same as or slightly larger than the diameter of the opening 31 of the through hole 3. The center ring 12 is preferably formed of a flexible material such as silicon, NBR (nitrile rubber), SBR (styrene butadiene rubber), or the like. Therefore, even when the diameter of the center ring 12 is slightly larger than the diameter of the opening 31 of the through hole 3, the center ring 12 is appropriately deformed so as to match the diameter of the opening 31. Further, as shown in FIG. 3, the center ring 12 is preferably installed at a substantially central portion in the thickness direction of the through-hole 3, so that the inner peripheral surface 42 of the tube member 4 and the inside of the through-hole 3 are arranged. Even when filling the filler 5 with the peripheral surface 32, the operator does not need to hold the pipe member 4 by himself / herself, and the above-described operation can be performed efficiently. Furthermore, as shown in FIG. 4, when the length of the through hole 3 in the thickness direction is long, the pipe member 4 is bent over the entire section inside the through hole 3 by using two center rings 12. There is no excuse. 3 and 4 show examples in which one or two center rings 12 are used, the number of the center rings 12 used can be changed as appropriate.

  Then, as shown in FIG. 4 (a), the center ring 12 is installed at a location about several centimeters from the opening 31 of the through hole 3 so that the operator can hold the pipe member 4 by himself / herself. At least the tube member 4 is held at the center of the opening 31 of the through hole 3, so that the work of filling the filler 5 can be simplified as described above, and the center ring 12 is provided with the filler 5. It also functions as a backup material. That is, when the length of the through hole 3 in the thickness direction is long, a large amount of filler 5 is filled in the entire section between the inner peripheral surface 32 of the through hole 3 and the outer peripheral surface 42 of the pipe member 4. Although the filler 5 is required, by installing the center ring 12 as described above, overfilling of the filler 5 can be prevented as shown in FIG. Further, by installing the center ring 12 inside the through hole 3, it is possible to contribute to improvement of the airtightness and watertightness inside and outside the structure 2. In the present embodiment, an example in which the center ring 12 is used is shown, but the tube member 4 is arranged at the center of the opening 31 of the through hole 3 by the projection 7 described later without using the center ring 12. Therefore, sufficient airtightness and watertightness can be ensured.

  Further, when the center ring 12 is installed inside the through hole 3, first, as shown in FIG. 1, the center ring 12 is formed at the approximate center and has a diameter substantially equal to the diameter of the opening of the tube member 4. The tube member 4 is inserted through the insertion hole 121 and the center ring 12 is externally fitted to the outer peripheral surface 42 of the tube member 4. Then, as shown in FIG. 3, the tube member 4 in which the center ring 12 is fitted on the outer peripheral surface 42 is inserted into the through hole 3. At this time, if the diameter of the center ring 12 is slightly larger than the diameter of the opening 31 of the through hole 3, friction occurs between the edge 122 of the center ring 12 and the inner peripheral surface 32 of the through hole 3. However, since the edge 123 of the insertion hole 121 of the center ring 12 is fitted into the screw groove 41 of the pipe member 4, the position of the center ring 12 does not shift. However, when the center ring 12 is inserted into the through-hole 3 through the tube member 4 fitted on the outer peripheral surface 42, the center ring 12 is displaced as shown in FIG. For example, a fitting groove 13 for fitting the edge 123 of the insertion hole 121 of the center ring 12 may be separately provided in the vicinity of the substantially center of the center ring 12, or in addition, as shown in FIG. As shown in FIG. 4, the locking protrusions 14 for preventing the position shift of the center ring 12 are provided so as to extend over the outer diameter direction of the outer peripheral surface 42 of the tube member 4 or partially in the outer diameter direction. You may do it.

  For example, as shown in FIG. 1, the one-side lid member 6a is screwed into the pipe member 4 from one side of the pipe member 4 inserted through the through-hole 3, or as shown in FIG. 4 is formed in advance on one side. And these one side cover members 6a are formed so that the opening part 31 of the one side of the through-hole 3 may be covered. On the other hand, the other side cover member 6b is screwed into the tube member 4 from the other side of the tube member 4 inserted into the through hole 3 as shown in FIG. 31 is formed so as to cover 31. Further, a screw having a screw groove 62 formed on the outer peripheral surface 42 of the tube member 4 and a screw groove 62 screwed into the inner peripheral surface 63 at the approximate center of the one side cover member 6a and the other side cover member 6b. A hole 64 is provided. The opening side surfaces 61a and 61b of at least one of the through holes 3 in the one side lid member 6a and the other side lid member 6b protrude from the opening side surfaces 61a and 61b toward the opening 31 of the through hole 3. As shown, a projection 7 that guides the tube member 4 to the center of the opening 31 of the through hole 3 is formed. Further, in the present embodiment, the projections 7 have a diameter substantially equal to the diameter of the opening 31 of the through hole 3 and are formed at three equal intervals on the concentric outer side of the screw hole 64.

  As shown in FIG. 1, the protrusion 7 gradually increases from the at least one opening side surface 61 a, 61 b of the one side lid member 6 a and the other side lid member 6 b toward the opening 31 of the through hole 3. An inclined surface 71 is formed so that the side cuts out a part of the rectangular parallelepiped in the diameter reducing direction. A flat portion 72 that contacts the inner peripheral surface 32 of the through hole 3 is formed on the outer peripheral side of the protrusion 7. Therefore, when the one side lid member 6a and the other side lid member 6b are attached from both sides of the through hole 3 so as to cover the opening 31 of the through hole 3, as shown in FIG. 4 is held at the center of the opening 31 of the through hole 3. Even if a construction error occurs in the opening 31 of the through hole 3, the inclined surface 71 of the protrusion 7 reliably guides the tube member 4 to the center of the opening 31 of the through hole 3. That is, when the projection 7 is made of a synthetic resin, after the pipe member 4 is guided to the center of the opening 31, the flat portion 72 penetrates by being deformed by friction between the projection 7 and the opening 31. It abuts on the inner peripheral surface 32 of the hole 3. Further, when the projection 7 is made of metal, the projection 7 spreads the opening 31, and the flat portion 72 contacts the inner peripheral surface of the through hole 3. If the projection is provided at least on either the side lid member 6a or the other side lid member 6b, the tube member 4 can be reliably guided to the center of the opening 31 of the through hole 3. Therefore, when the filler 5 is filled between the outer peripheral surface 42 of the tube member 4 and the inner peripheral surface 32 of the through-hole 3, the thickness of the filler 5 on the outer peripheral surface 42 of the tube member 4 is uniform. Therefore, airtightness and watertightness can be reliably ensured. Further, in that case, even if an external force is applied to the tube member 4 before the filler 5 is cured, the position of the tube member 4 with respect to the opening 31 of the through hole 3 does not change, and the tube member 4 is always moved. It can hold | maintain in the opening part 31 center of the through-hole 3, and defects, such as a water leak, do not occur after construction.

  In addition, the one-side lid member 6a and the projection 7 or the other-side lid member 6b and the projection 7 are preferably made of inexpensive and excellent moldability, such as a versatile synthetic resin such as vinyl chloride or polypropylene. May be selected as appropriate according to the application. However, the shape, thickness, and material of the one-side lid member 6a and the other-side lid member 6b are not limited to those of the present embodiment, but at least the one-side lid member 6a and the other side As long as the lid member 6b has a shape that can cover the opening 31 of the through-hole 3, it can be appropriately changed. Further, the shape of the protrusion 7 is not limited to the above-described shape, and as shown in FIG. 15 described later, the protrusion 7 has at least one side surface 61 of the one-side lid member 6a and the other-side lid member 6b. In addition, it may be formed in a substantially truncated cone shape whose diameter decreases as the distance from the side surface 61 increases, or may be another shape.

  An embodiment of the through-pipe 1 configured as described above will be described below. A through-pipe 1 according to the first embodiment is shown below. As shown in FIG. 1, the through-pipe 1 according to the first embodiment is formed of the pipe member 4, the center ring 12, the one-side lid member 6 a, and the other-side lid member 6 b described above. In the present embodiment, the one-side lid member 6a and the other-side lid member 6b are both formed so that the overall shape thereof is a substantially disk shape having a predetermined thickness, and a tube member is provided at the substantially center thereof. A screw hole 64 having a screw groove 62 that is screwed into the screw groove 41 formed on the outer peripheral surface 42 of the inner peripheral surface 63 is formed. Further, it is preferable that a groove 66 for preventing slippage is formed in the outer edge portion 65 of the one side lid member 6a and the other side lid member 6b.

  When attaching the pipe member 4 to the through hole 3, first, the center ring 12 is attached to the pipe member 4, and the pipe member 4 is inserted into the through hole 3. In this case, as shown in FIG. 3 (a), the center ring 12 is installed at a substantially central portion in the thickness direction of the through hole 3, so that the filling work of the filler 5 in the next step is facilitated. Therefore, it is preferable. Then, the filler 5 is filled from the openings 31 on both sides of the through hole 3. In this state, the pipe member 4 is held at the center of the opening 31 of the through hole 3 by the center ring 12, so that the thickness of the filler 5 is uniform on the outer peripheral surface 42 of the pipe member 4. Filled. Next, the openings 31 on both sides of the through-hole 3 are covered with the one-side lid member 6a and the other-side lid member 6b, and the side surfaces 21 of the structure 2 are in contact with each other. Tighten to the opening side 31. At this time, the projections 7 formed on the opening side surfaces 61 a and 61 b of the through hole 3 of the one side lid member 6 a and the other side lid member 6 b cause the tube member 4 to be centered on the opening 31 of the through hole 3. Lead. Even if an external force is applied to the tube member 4 before the filler 5 is cured, the tube member 4 can always be held at the center of the opening 31 of the through hole 3.

As shown in FIG. 1, the through-pipe 1 according to the second embodiment is formed of the pipe member 4, the center ring 12, the one-side lid member 6a, and the other-side lid member 6b described above. The one-side lid member 6a and the other-side lid member 6b have the same shape as the one-side lid member 6a and the other-side lid member 6b according to the first embodiment. As shown in FIG. 4, the length in the thickness direction of the through hole 3 according to this embodiment is longer than the length in the thickness direction of the through hole 3 according to the first embodiment shown in FIG. Is formed. Therefore, as shown in FIG. 4A, one center ring 12 is installed at a position several centimeters inside from the openings 31 on both sides of the through hole 3. Thereby, the pipe member 4 does not bend over the entire section inside the through hole 3, and the filler 5 is filled between the outer peripheral surface 42 of the pipe member 4 and the inner peripheral surface 32 of the through hole 3. Also when performing the operation | work to perform, as shown in FIG.4 (b), the overfilling of the filler 5 can be prevented. Furthermore, since the pipe member 4 is not bent and the position of the through-hole 3 of the pipe member 4 with respect to the opening 31 is not shifted, the pipe member 4 can always be held at the center of the opening 31. The method of attaching the tube member 4 to the through hole 3 is the same as that of the first embodiment except that two center rings 12 are provided.

  A through pipe 1 according to the third embodiment is shown below. As shown in FIG. 2, the through-pipe fitting 1 according to the third embodiment is formed of the pipe member 4, the center ring 12, the one-side lid member 6a, and the other-side lid member 6b described above.

Then, the filler 5 is filled from the gap between the one-side lid member 6a and the opening 31 of the through hole 3, and the one-side lid member 6a and the side surface 21 of the structure 2 abut so as to close the gap. The tube member 4 is pushed in. Then, after filling the filler 5 also from the opening 31 on the other side of the through-hole 3, the other side lid member 6b may be tightened to the opening 31 side. By doing so, compared to the first and second embodiments, the work of tightening the one-side lid member 6a toward the opening 31 on the one side of the through hole 3 can be omitted, so that the work efficiency is further improved. Can be improved, and airtightness and watertightness can be reliably ensured. Moreover, in this embodiment, although the one side cover member 6a is formed in advance in the tube member 4, it is formed in the tube member 4 in advance in either the one side cover member 6a or the other side cover member 6b.

As shown in FIG. 10, the through piping device 1 according to the fifth embodiment is formed of the pipe member 4, the center ring 12, the one-side lid member 6 a, and the other-side lid member 6 b described above. In addition, the other-side lid member 6b according to the present embodiment uses the same shape as that of the first to fourth embodiments. However, as shown in FIG. 11, the one-side lid member 6 a is an attachment frame 152 for attaching the waterproof outlet 15 described above to the side surface 21 of the structure 2. That is, as shown in FIG. 10, a screw hole 152f having a screw groove 152e is formed in the inner peripheral surface 152d at a substantially center of the mounting frame 152, and the protrusion 7 is provided in the same manner as the one-side cover member 6a. The opening 31 of the through hole 3 is covered. Therefore, as shown in FIG. 12, the attachment frame 152 covers the opening 31 of the through-hole 3, and the attachment frame 152 is arranged so that the inner side surface 152 c of the attachment frame 152 contacts the side surface 21 of the structure 2. The tube member 4 is screwed. Therefore, the tube member 4 can be attached to the center of the opening 31 of the through hole 3 as in the first embodiment, and as shown in FIG. 12, the packing 154 and the case 151 are provided outside the attachment frame 152. Can be installed. By doing so, the work of attaching the waterproof outlet 15 to the side surface 21 of the structure 2 can be easily performed, and airtightness and watertightness can be reliably ensured. Moreover, the attachment method of the pipe member 4 to the through-hole 3 is as described above except that the one-side lid member 6a becomes the attachment frame 152.

  In the fourth embodiment and the fifth embodiment described above, as shown in FIGS. 9 and 12, the example in which the filler 5 is filled from both sides of the structure 2 has been shown. As shown in FIG. 13 and FIG. 14, these are filled with the filler 5 only on the outdoor side where the waterproof outlet 15 is attached, and the outdoor side one side cover member (mounting frame) 6 a ( 152), the protrusion 7 may not be provided. The filler 5 is also filled only in the vicinity of the opening 31 on the outdoor side. By doing so, when the one-side lid member (mounting frame) 6a (152) is screwed into the pipe member 4, the shape of the filler 5 uniformly filled in the vicinity of the opening 31 on the outdoor side can be disturbed. In addition, airtightness and watertightness can be reliably ensured. Further, as shown in FIGS. 13 and 14, it is also possible to use the projection 7 of the other side lid member 6 b in which a truncated cone-shaped projection 7 described later is formed.

However, as shown in FIG. 15, the protrusions 7 formed on the one side lid member 6 a and the other side lid member 6 b protrude from the side surfaces 61 on one side and shrink as the overall shape separates from the side surface 61. It is formed so as to have a substantially frustoconical shape with a diameter. In this case, screw grooves 63 may also be formed on the inner peripheral surface of the protrusion 7.

  And in this embodiment, although the shape of the one side cover member 6a and the other side cover member 6b is using the same thing, when attaching the pipe member 4 to the through-hole 3 using these, As shown in FIG. 15, the substantially frustoconical protrusion 7 formed on the one-side lid member 6 a is inserted into the opening 31. The other side lid member 6b covers the opening 31 with a side surface 61 on which no projection 7 is formed. In this way, when the other side member 6b is screwed to the tube member 4, the shape of the filler 5 uniformly filled in the vicinity of the opening 31 on the other side is not disturbed, and airtightness and watertightness are achieved. It can be surely secured. In addition, as for the one-side lid member 6a used at this time, it is easier to use the one in which the one-side lid member 6a is previously formed on the tube member 4 as in the third embodiment. Although it is preferable, the same effect can be obtained even if the tube member 4 and the one-side lid member 6a are separated as in the first embodiment. In this case, it is preferable from the viewpoint of ensuring airtightness and watertightness that the side filled with the filler 5 shown in FIG. 15 is, for example, the outdoor side. Also in this embodiment, the center ring 12 may be used as shown in FIG. 15A, or the center ring 12 may not be used as shown in FIG. The operator can select it.
