Description

  The present invention relates to a joint fixture for fixing various pipe joints such as a cheese type (T-shaped) pipe joint to a wall surface (including a ceiling surface and a floor surface).

  2. Description of the Related Art Conventionally, a clamp-shaped fixture disclosed in FIG. 6 of Patent Document 1 (Japanese Patent Laid-Open No. 2002-354637) is known as a fixture for fixing a pipe material such as a water supply / hot water supply pipe to a wall surface. In this fixing device, a belt-like body is formed in an annular shape to serve as a holding portion of the pipe material, while both end portions are overlapped to provide a through hole, and the pipe material such as a synthetic resin pipe is fixed to the wall surface with a nail, a screw or the like. It is something to hold. Moreover, what was disclosed by the said patent document is related with the fixing tool which formed the through-hole in the holding piece so that it could attach ahead of a wall surface. And in order to hold | maintain soft pipe | tubes, such as a synthetic resin pipe | tube, the fixing tool was attached at about 1-meter space | interval.

  On the other hand, in the middle of the pipe line, a branch pipe joint such as a cheese type pipe joint is used in order to secure a necessary pipe line. In order to fix these pipe joints to the wall surface, a mounting seat is provided on the pipe joint itself, and is directly fixed to the wall surface via this mounting seat.

JP 2002-354637 A

  By the way, when piping using conventional fixtures and pipe joints, the pipe joints are directly fixed to the wall surface via the mounting seat as described above, so that vibration occurs in the pipe line due to the so-called water hammer phenomenon. In this case, there is a problem that the pipe joint directly collides with the wall surface due to the movement of the pipe joint, and the pipe joint and the wall surface are damaged. In addition, in order to restrict the movement of the pipe joint, the fixing tool is attached to the pipe part nearest to the pipe joint, and many fixing tools are required to fix the pipe material. At the same time, there was a problem that the cost increased. Moreover, it is necessary to prepare a plurality of types of fixtures according to the diameter of the pipe material.

  Furthermore, when the cheese tube is attached to the wall surface via the mounting seat, the branch direction is fixed, so that there is a problem that the branch direction of the branch tube cannot be freely selected.

  On the other hand, in recent years, for example, as disclosed in Japanese Patent Application Laid-Open No. 2006-97420 related to the applicant's application, a multilayer having a three-layer structure in which a metal layer is interposed in between and a resin layer is provided inside and outside the metal layer. Many tubes are used. The multilayer pipe having such a structure is excellent in creep resistance and has no precipitation of metal components, and can maintain a good water quality particularly in the case of clean water. Moreover, when such a multilayer pipe is used for piping, compared with the conventional soft pipe | tube, the attachment space | interval of the said fixing tool can be taken long, and a fixing tool can be attached at intervals of about 1.5-2 meters. This can reduce the labor and cost of construction. However, even when a multilayer pipe is used, when the pipe itself is fixed with a fixture, there remains a problem of vibration of the pipe joint resulting from the water hammer phenomenon.

  The present invention has been made to solve the above-described problems, and the invention described in claim 1 is a joint fixture for holding a joint body of a pipe joint and fixing the pipe joint to a wall surface, A holding body is extended in an annular shape from one end of the base, and a fixed piece is provided at the tip of the holding body so as to overlap and adhere to the other end of the base, and the base and the holding body have a predetermined inner diameter. A means for forming a joint holding part having a through hole and providing a through hole so as to communicate with the overlapping base and the fixed part is adopted.

  Further, in the invention described in claim 2, there is a plurality of through holes provided so as to be able to communicate with the base and the fixing portion, and the base and the base are changed by changing the corresponding positional relationship. A means for enabling the inner diameter of the joint holding portion formed by the holding body to be changed was adopted.

  Furthermore, the invention described in claim 3 employs a means for providing one or more window holes in the annular direction of the holding body in which the pipe end position of the pipe inserted into the holding joint can be visually recognized. .

  As another configuration, two joint fixtures according to any one of claims 1 to 3 are arranged, and each base is connected by a connecting plate having a predetermined width to form a joint fixture. Adopted a means to do.

  In addition, the joint fixture described in the above claims also employs a means that the whole is integrally molded with a flexible resin material.

  According to the first aspect of the present invention, the joint body of the pipe joint is elastically held on the joint holding portion formed by the base and the annularly curved holding body, and the pipe joint can be fixed to the wall surface. Therefore, the labor and cost of construction can be reduced as compared with the conventional method of holding the pipe material closest to the joint. Further, even when the pipe joint vibrates due to a water hammer phenomenon or the like, a direct collision between the pipe joint and the wall surface can be prevented, and both the wall surface and the pipe joint can be protected.

  In addition, since the joint body is held by the annular joint holding part, for example, when holding a branch pipe such as a cheese pipe, the branch direction can be changed after mounting, and the degree of freedom in handling the pipe is increased. The construction of the piping is easy.

  In addition, since a plurality of through holes that can communicate with each other are provided in the base and the fixed part, it is possible to change the inner diameter of the joint holding part step by step by changing the corresponding positional relationship of the through holes that communicate with each other. Therefore, it has become possible to cope with pipe joints of various sizes.

  Further, since the window hole is provided in the annular direction of the holding body, when the joint body holds the pipe joint made of a transparent member, the pipe end of the pipe inserted into the joint is passed through the window hole and the transparent joint main end. The position could be easily confirmed, and the certainty of enforcement was improved.

  On the other hand, since the joint fixtures of each of the above configurations are arranged and connected by a connection plate to configure the joint fixture, particularly when fixing a pipe joint such as a cheese tube, various effects in the single unit can be expected, A cheese tube or the like can be integrally protected.

  These joint fixtures are integrally formed of a flexible resin material so as to be interposed between the pipe joint and the wall surface to prevent direct collision between the two and to absorb both impacts. Can be protected together.

  Hereinafter, a preferred embodiment of a joint fixture according to the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1: shows the outline | summary of 1st Embodiment of the coupling fixture which concerns on this invention, (A) is a front view, (B) is a rear view, (C) is a side view, (D) is a perspective view. It is.

  In the figure, 1 is a flat base, and 2 is a belt-like holding body that is curved and extended in an annular shape from one end of the base 1. A fixing piece 3 is formed at the tip of the holding body 2 so as to be in close contact with the other end of the base 1. This holding body 2 has elasticity, and by lifting the fixing piece 3, the space between the base 1 and the fixing piece 3 is expanded, the joint can be inserted, and the fixing piece 3 is brought into close contact again. The base 1 and the annular holder 2 form a joint holding part 4 having a predetermined inner diameter. Reference numeral 5 denotes an attachment piece extending to the side of the base 1 in order to fix the base 1 to the wall surface in advance, and has a through hole 6 for passing a nail or a screw. The attachment piece 5 may be provided as necessary and may be omitted.

  Reference numeral 7 denotes a plurality of through holes provided in the base 1 and communicates with the plurality of through holes 8 provided in the fixed piece 3. The through-hole 7 and the through-hole 8 can change the inner diameter of the joint holding part 4 by changing the corresponding positional relationship to communicate with each other, so as to be compatible with a plurality of types of joints. Yes. That is, for example, in FIG. 1, the base 1 is provided with three through holes 7a, 7b, 7c at predetermined intervals in the left-right direction and the front-rear direction, while the fixed piece 3 has predetermined intervals in the left-right direction. Two through holes 8a and 8b are provided. In this case, the vertical position of the fixing piece 3 with respect to the base 1 is changed by associating the through holes of 7a and 8b, 7b and 8a, and 7c and 8b, respectively. As a result, the joint formed by the holding body 2 The diameter of the holding part 4 can be changed into three types.

  Reference numeral 9 denotes a rib provided along the annular direction of the holding body 2 for maintaining the elasticity and strength of the holding body 2 appropriately.

  The joint fixture is obtained by integrally molding a flexible synthetic resin, but is not limited thereto, and can be obtained by bending an appropriate metal material. However, even in this case, the holding body 2 must be capable of holding the joint elastically. In addition, a joint fixture of several kinds of colors may be prepared by appropriately changing or coloring the color of the synthetic resin material. Thereby, for example, when fixing to a pipe joint in advance, if it is color-coded for each usage such as for water supply and for hot water supply, identification at the time of construction becomes easy.

  FIG. 2 shows an example of use in which two joint fixtures 10 are used and attached to a cheese pipe as a pipe joint, (A) is a front view, and (B) is a side view.

  In the figure, 11 is a cheese pipe, and a joint 12 is formed on the left and right pipe ends, and a branch joint 13 is formed in a direction perpendicular to the center. In the case of the figure, the joint fixtures 10 are respectively mounted on the joint bodies 12a of the left and right joints 12, and the joint portions of the cheese tube 11 are securely fixed. Specifically, joint fixtures 10 and 10 are mounted in advance on the joint portion, and a trunk pipe (not shown) is connected to the joint 12 at the left and right ends. Next, a nail, a screw, or the like is inserted into the through holes 7 and 8, and the joint fixture 10 is fixed to the wall surface while confirming the direction of the branch joint 13. Next, a branch pipe (not shown) is connected to the branch joint 13. In this case, the above-described multilayer pipe is preferably used for the trunk pipe and the branch pipe. That is, when a pipe is connected to a joint by using a multi-layer pipe having creep resistance, the pipe nearest to the joint is not fixed with a fixture as in the prior art. By fixing with the joint fixing tool, it is possible to greatly reduce the use place of the fixing tool, which is advantageous in terms of cost. It is also possible to temporarily fix the joint fixture to the wall surface first and attach the pipe joint later.

  By fixing the joint portion with the two joint fixtures 10 and 10 in this way, even when the cheese tube vibrates due to the water hammer phenomenon, it does not come into direct contact with the wall surface. A cheese tube can also be protected. Further, since the cheese tube itself is not directly fixed to the wall surface, the cheese tube 11 can be rotated in the joint holding portion 4 and the direction of the branch joint 13 can be changed even after the fixing.

  The joint 12 can be connected to a pipe by inserting a trunk pipe or a branch pipe (not shown) and fastening the fastening ring 12b. However, the type of joint is not limited to this, and is publicly known. Various joint structures can be adopted. However, as illustrated, it is preferable that the outer diameter of the joint body 12a is slightly smaller than the outer diameter of the tightening ring 12b, and a step 12c is formed between the two. In other words, the movement of the holder 2 of the joint fixture 10 is restricted by the step 12c, and the cheese tube can be more reliably fixed.

  In the above embodiment, the cheese tube has been described as an example. However, the joint fixture according to the present invention is not limited to the cheese tube, and can be widely applied to various pipe joints having a predetermined joint at the pipe end.

Thereby, the annular holding body 25 forms a joint holding portion 27 having a predetermined diameter. In addition, the fixed piece 26 is provided with a plurality of through holes 28, 28, and a plurality of through holes (not shown) provided in the base 23 are communicated so that the corresponding positions can be changed so that nails or the like can be inserted. . Thereby, it can respond to the some joint from which a diameter differs similarly to the said 1st Embodiment. Then, the bases 23 of the fixed part 22 having such a configuration are connected to each other with a flat connecting plate 24 at a predetermined interval. Such a joint fixture is easy to apply to, for example, a cheese tube. Further, if the connecting plate 24 is flexible, it can be adapted to an elbow tube or the like by being bent. Further, a through hole (not shown) for wall surface attachment may be formed in the connecting plate.

  29, 29... Are window holes provided in the annular direction of the holding body 25. As described below, when a trunk pipe or the like is inserted into the fitting body of the fitted pipe joint, The insertion position of a pipe end such as a trunk pipe can be visually confirmed, and it can be confirmed that the trunk pipe or the like is reliably inserted into the joint. Since the viewing direction changes according to the fixing position of the joint fixture 21, the window holes 29 are provided at a plurality of locations in the annular direction. In addition, this window hole is applicable also to the joint fixing tool in 1st Embodiment mentioned above. That is, when the joint body of the pipe joint to be fixed is transparent, the insertion position of the pipe end is made visible through the window hole.

  In addition, the joint fixture of the said structure can also be obtained by integrally molding a flexible resin material similarly to 1st Embodiment. Furthermore, it may be colored appropriately so that the type of piping can be identified.

  3D and 3E, the example of use attached to a cheese pipe as a pipe joint will be described. In the figure, 30 is a cheese pipe, and a joint 31 is formed on the left and right pipe ends. The branch joint 32 is formed in a right angle direction from the top. The joint 31 can be connected and fixed to a trunk pipe or the like by fastening a fastening ring 31b to the joint body 31a. However, the joint body 31a is formed of a transparent synthetic resin, and a pipe end portion of the inserted trunk pipe or the like. Can be seen through, and it can be confirmed that the tube is securely inserted. In the case of the figure, the transparent joint main body 31 a portions of the left and right joints are inserted and fixed in the respective joint holding portions 27 of the holding body 25, and attached to the wall surface through the through holes 28 of the fixing pieces 26. At this time, when the trunk pipe is connected, the insertion state of the pipe can be visually confirmed through the window hole 29 of the holding body 25 and the transparent joint body 31a, and it can be confirmed whether or not the pipe is securely inserted.
