Description

  The present invention relates to a pipe bundling member for temporarily bundling a plurality of pipes, for example, when carrying pipes into a construction site or installing pipes.

  Conventionally, a plurality of pipes are arranged side by side in existing pipes such as sewer pipes and industrial water pipes, and in treatment water tanks and sedimentation tanks such as sewage treatment plants and wastewater treatment facilities, and flow through the existing pipes. 2. Description of the Related Art A heat collection system that exchanges heat between a liquid or a liquid in a treated water tank and a heat exchange medium flowing in a plurality of pipes is known.

  For example, in Patent Document 1, a plurality of continuous heat collecting tubes that start from a manhole, are folded back, and return to the manhole again are laid in parallel to the longitudinal direction of the inner peripheral surface of the tube bottom of an existing tube or a new tube. Thus, a heat collection structure such as sewage heat for exchanging heat between the heat exchange medium and sewage is disclosed.

JP 2013-242107 A

  By the way, pipes arranged as heat collection pipes in existing pipes or treated water tanks, for example, have many long objects exceeding 50 m, for example. It is carried into the construction site in a coiled state (for example, a drum). Thus, when constructing a heat collection system, pipes are often drawn into existing pipes or treated water tanks while being unwound one by one from a rotating drum.

  However, when there are many pipes, if one long pipe is drawn into the existing pipe or the treated water tank one by one, there is a problem that the working efficiency is greatly reduced. On the other hand, if pipes wound in the shape of a coil are randomly inserted into existing pipes or treated water tanks, long pipes will be entangled with each other, so it takes a lot of time to arrange the pipes side by side. However, there is a problem that the working efficiency is greatly reduced.

  Therefore, in order to suppress a decrease in work efficiency, for example, it is considered that a plurality of pipes are bundled so as to be knitted using a binding band such as Insulok (registered trademark), and the bundle of the plurality of pipes is drawn into an existing pipe or a treated water tank. It is done.

  However, the conventional binding band has the following problems. That is, when installing a plurality of pipes, it is necessary to remove the binding band for temporary binding from the pipe, but there is a problem that the binding bands knitted into the plurality of pipes are difficult to remove. Furthermore, this type of binding band also has the problem of being uneconomical because it is premised on disposable, for example, by cutting and removing the binding band.

  The present invention has been made in view of such points, and the object of the present invention is to improve workability when bundling and constructing a plurality of pipes, and can be easily detached from the pipes. It is providing the bundling member for pipes which can be improved.

  In order to achieve the above object, in the present invention, a plurality of pipes are temporarily bundled by sandwiching the pipes with the bundling members instead of knitting the bundling members into the pipes.

  Specifically, the present invention is directed to a pipe bundling member that temporarily bundles a plurality of pipes.

  The pipe bundling member includes a substrate and a plurality of ribs protruding side by side on one side of the substrate, and sandwiching the pipes between the plurality of ribs, thereby It is characterized by unity.

  According to this configuration, a plurality of pipes can be easily bundled by sandwiching the pipes between the plurality of ribs, and the pipe binding member can be easily removed from the pipes by pulling the pipes between the ribs. Can do. In addition, since the plurality of pipes are bundled by the plurality of ribs provided side by side on the substrate, the plurality of pipes are temporarily bundled in a side-by-side state, so that the plurality of pipes can be easily aligned in a side-by-side state. . Furthermore, since this pipe bundling member can be used repeatedly even after it has been used once, it is possible to improve the economy as compared with a conventional bundling band premised on disposable.

  The pipe bundling member includes a substantially rectangular substrate constituting the substrate, the plurality of ribs projecting from one side of the substrate so as to be aligned in the longitudinal direction of the substrate, A single member having a pair of connecting portions formed at both ends in the longitudinal direction of the single substrate is connected by a plurality of the connecting members in the longitudinal direction by the connecting portions, and is long from the connecting portion as a base point. It is preferably bendable along the direction.

  According to this configuration, the pipe bundling member is formed by connecting a plurality of single members and can be bent along the longitudinal direction (around the direction perpendicular to the longitudinal direction) with the connecting portion as a base point. A plurality of pipes can be rounded in the direction of arrangement. Accordingly, for example, even in a narrow place where it is difficult to pass a plurality of pipes in a side-by-side state, the plurality of pipes can be easily passed while being temporarily bound by rounding the plurality of pipes in the arrangement direction. Further, by rounding a plurality of pipes in the arrangement direction, for example, pipes in existing pipes such as sewer pipes and industrial water pipes can be easily handled.

  Furthermore, it is preferable that the connecting portions that are paired with each other are connected so as to be rotatable around a direction perpendicular to the longitudinal direction. According to this structure, the binding member for pipes can be easily bent along the longitudinal direction with the pivotable connecting portion as a base point.

  By the way, as a usage example of the pipe bundling member of the present invention, in a factory or the like, a plurality of pipes are temporarily bundled every few meters by a pipe bundling member, and the plurality of temporarily bundled pipes are used as one rotating drum or the like. It is conceivable that the rotating drum is wound around the construction site and carried into a construction site or the like, and drawn into the existing pipe or the treated water tank while simultaneously unwinding a plurality of pipes. Thus, when a plurality of pipes are temporarily bundled every few meters by a pipe bundling member in a factory or the like, a plurality of supply drums each having a pipe wound around are installed side by side. It is conceivable to temporarily bind a plurality of pipes with a pipe binding member while simultaneously unwinding a plurality of pipes.

  However, the pipe arrangement interval (rib arrangement interval) in the pipe bundling member is usually narrower than the arrangement interval of the supply drums. For this reason, when bundling a plurality of pipes that are simultaneously unwound from a plurality of supply drums installed side by side with a bundling member for a pipe, for example, the pipe is bent extremely, or the pipe is gently pulled out by tens of meters. Or the like, the difference between the arrangement interval of the ribs and the arrangement interval of the supply drums must be eliminated, which may damage the pipe and make it difficult to secure a space.

  Therefore, it is preferable that the pipe bundling member can be bent with the connecting portion as a base point so that the longitudinally perpendicular direction of the plurality of single members is radial. According to this configuration, the pipe bundling member is curved with the connecting portion as a base point, and the rib extending direction of each single member is directed toward the corresponding supply drum, whereby the rib arrangement interval and the supply drum arrangement are arranged. The difference from the interval can be easily eliminated.

  Also, in the pipe binding member, the single member is made of resin, and the connecting portion that is paired with each other is connected at one end to one end in the longitudinal direction of the substrate alone, in the direction perpendicular to the longitudinal direction. A rod-shaped first connecting part extending in the direction of the first substrate, and a second connecting part having a hole extending in the direction perpendicular to the longitudinal direction into which the first connecting part can be inserted, and formed on the other end in the longitudinal direction of the substrate alone. Preferably, the first connecting portion is deformable such that the other end is separated from the end portion on one side in the longitudinal direction of the substrate alone.

  According to this configuration, by inserting the rod-shaped first connecting part extending in the direction perpendicular to the longitudinal direction into the hole extending in the direction perpendicular to the longitudinal direction of the second coupling part, the adjacent single members can be rotated around the direction perpendicular to the longitudinal direction. Can be linked to. Also, by deforming the rod-shaped first connecting portion inserted into the hole of the second connecting portion so that the other end thereof is separated from the end portion on one side in the longitudinal direction of the substrate alone with the one end as a base point. The single members adjacent to each other can be opened in a fan shape with the connecting portion including the first and second connecting portions as a base point. Therefore, the binding member for pipes can be easily bent with the connecting portion as a base point.

  By the way, in the above-described pipe binding member, a plurality of pipes can be bundled by sandwiching the pipe between the plurality of ribs, but depending on the shape of the rib, the pipe binding member may slide along the pipe. .

  Therefore, the rib is preferably formed in a shape that follows the outer shape of the pipe. According to this structure, since a pipe fits firmly between ribs, it can suppress that the binding member for pipes slides along a pipe.

  As described above, according to the bundling member for pipes according to the present invention, since a plurality of pipes are bundled by sandwiching the pipes between a plurality of ribs, the workability is improved and the pipes can be easily detached from the pipes. Can do. Furthermore, since it can be used repeatedly, economic efficiency can be improved.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a pipe bundling member 1 according to this embodiment, FIG. 2 is a plan view showing a single member 11 constituting the pipe bundling member 1, and FIG. 3 is an AA view of FIG. FIG. 4 is an end view taken along the arrow, and FIG. 4 is an end view taken along the arrow B-B in FIG. 2.

  As shown in FIG. 1, the pipe binding member 1 includes a substrate 2 composed of a substantially rectangular substrate 12, and a plurality of juxtaposed projections on the upper surface (one side surface) of the substrate 2 (example of FIG. 1). Then, the rib 3 of 12) is provided. This pipe binding member 1 is for temporarily binding a plurality of pipes 20, and is configured to bind a plurality of pipes 20 by sandwiching the pipes 20 between adjacent ribs 3 ( (See FIG. 5).

  As the pipe 20 to which the pipe binding member 1 is applied, for example, heat collection constructed in an existing pipe such as a sewer pipe or an industrial water pipe, or in a treated water tank such as a sewage treatment plant or a waste water treatment facility. Although the heat collection pipe | tube of a system can be mentioned, you may apply the bundling member 1 for pipes to the pipe 20 used for uses other than these. Further, examples of the material of the pipe 20 to which the pipe binding member 1 is applied include olefin-based thermoplastic resins such as polyethylene and polypropylene, but resins, rubbers and metals other than thermoplastic resins may be used. Good.

  As shown in FIG. 1, the pipe binding member 1 is formed by connecting a plurality of single members 11 in the longitudinal direction by connecting portions 4. In addition, in FIG. 1, although the example which connected the single member 11 was shown, the number of the single members 11 which comprise the binding member 1 for pipes may be two, and four or more may be sufficient as them.

  Each single member 11 is made of resin, and, as shown in FIGS. 2 to 4, a single substrate 12, a plurality of (four in the example of FIG. 2) ribs 3, and first and second pairs that are paired with each other. The connecting portions 14 and 15 and the guide portion 16 are provided.

  The board | substrate simple substance 12 is formed in the substantially rectangular plate shape, and comprises the board | substrate 2 in the binding member 1 for pipes. Four ribs 3 are provided on the upper surface (one side surface) of the single substrate 12 so as to be aligned in the longitudinal direction of the single substrate 12 (left and right direction in FIG. 2). It extends to. The two ribs 3 at both ends in the longitudinal direction have their tip portions (upper end portions) curved in an arc shape toward the inside in the longitudinal direction. On the other hand, the two ribs 3 in the central portion in the longitudinal direction are bifurcated at their tip portions and are each curved in an arc shape. The guide part 16 is formed in the central part of the substrate single body 12 in the direction perpendicular to the longitudinal direction, and connects the adjacent ribs 3 to each other. Each guide portion 16 is formed in a shape in which a rectangular plate-like member is cut out in a semicircular shape.

  By having the rib 3 and the guide portion 16 as described above, each single member 11 has the tip of the rib 3 curved in an arc shape when the pipe 20 is sandwiched between the four ribs 3 as shown in FIG. The portions are in close contact with each other along the outer peripheral surface of the pipe 20, and the guide portions 16 are in close contact with each other along the outer peripheral surface of the lower half of the pipe 20 to temporarily bind the three pipes 20.

  The first connecting portion 14 is formed at an end portion on one side (right side in FIG. 2) in the longitudinal direction of the substrate 12 alone. The first connecting portion 14 includes a rod-shaped large-diameter portion 14c extending in the direction perpendicular to the longitudinal direction, a rod-shaped small-diameter portion 14b extending in the longitudinally perpendicular direction from the tip of the large-diameter portion 14c and having a smaller diameter than the large-diameter portion 14c, and a small-diameter A substantially conical locking portion 14a formed at the tip of the portion 14b, and has a rod shape extending in the direction perpendicular to the longitudinal direction as a whole. The first connecting portion 14 has a base end portion (one end) 14 d connected to an end portion on one side in the longitudinal direction of the substrate 12 alone. A slit 14e is formed in the small diameter portion 14b and the locking portion 14a so as to divide the small diameter portion 14b and the locking portion 14a vertically.

  The second connecting portion 15 is formed at the other end (left side in FIG. 2) in the longitudinal direction of the substrate 12 alone. The second connecting portion 15 has a cylindrical shape extending in a direction perpendicular to the longitudinal direction, and has a hole 15a having a circular cross section into which the first connecting portion 14 can be inserted.

  The first connecting portion 14 and the second connecting portion 15 are paired with each other. Then, the 1st connection part 14 and the 2nd connection part 15 of the single-piece | unit member 11 which adjoins each other are comprised, and the connection part 4 in the binding member 1 for pipes is comprised.

  The first connecting part 14 and the second connecting part 15 are connected by inserting the rod-like first connecting part 14 into the hole 15 a of the second connecting part 15. More specifically, when the substantially conical locking portion 14a of the first connecting portion 14 is pushed into the hole 15a of the second connecting portion 15, the slit 14e is closed, and a part of the small diameter portion 14b and the large diameter portion 14c are holes. While being accommodated in 15a, the latching | locking part 14a protrudes from the hole 15a. Then, when the locking portion 14a jumps out of the hole 15a, the slit 14e is opened, and the locking portion 14a is hooked on the end of the second connecting portion 15. Therefore, the connection between the first connecting portion 14 and the second connecting portion 15 is not easily released unless the slit 14e is closed by intentionally holding the engaging portion 14a up and down.

  Here, since the 1st connection part 14 and the 2nd connection part 15 are connected by inserting the rod-shaped 1st connection part 14 in the hole 15a with a circular cross section, it can rotate to a longitudinal right-angle direction. It is connected to. Therefore, as shown in FIG. 6, the pipe binding member 1 can be bent along the longitudinal direction (around the direction perpendicular to the longitudinal direction) with the connecting portion 4 as a base point. Therefore, when the pipe bundling member 1 of the present embodiment is used, the plurality of pipes 20 bundled in a side-by-side state can be easily rounded in the arrangement direction. Thereby, for example, even in a narrow place where it is difficult to pass a plurality of pipes 20 in a side-by-side state, the plurality of pipes 20 can be easily passed while being temporarily bound by rounding the plurality of pipes 20 in the arrangement direction. it can. Further, by rounding the plurality of pipes 20 in the arrangement direction, the pipes 20 can be easily handled in existing pipes such as sewer pipes and industrial water pipes.

  Further, since the single member 11 is made of resin, the first connecting portion 14 has the base end portion 14 d as a base point so that the locking portion 14 a (the other end) is separated from the one end portion of the substrate single body 12. It can be deformed. Accordingly, if the first connecting portion 14 inserted into the hole 15a of the second connecting portion 15 is deformed so that the locking portion 14a is separated from the end portion of the substrate 12 alone, the base end portion 14d is used as a base point. The adjacent single members 11 can be opened like a fan. In other words, as shown in FIG. 7, the pipe bundling member 1 is configured such that a plurality of (three in the example of FIG. 7) single-piece members 11 constituting the pipe bundling member 1 are radial in the longitudinal direction. It is possible to bend with the connecting portion 4 as a base point.

  As an example of use of the pipe bundling member 1 configured as described above, a plurality of pipes 20 are temporarily bundled every few meters by a pipe bundling member 1 in a factory or the like. As shown in FIG. It is conceivable that a plurality of bundled pipes 20 are wound around one rotary drum 30, and the rotary drum 30 is carried into a construction site or the like and drawn into an existing pipe or a treated water tank while simultaneously unwinding the plurality of pipes 20. . If it does in this way, while working efficiency can be improved significantly, the several pipe 20 scheduled to be installed in a line-up state can be easily arranged in a line-up state in the construction stage.

  Thus, when a plurality of pipes 20 are bundled every few meters by the pipe bundling member 1 in a factory or the like, a plurality of supply drums 31 each having one pipe 20 wound thereon are provided as shown in FIG. It is conceivable that the pipes are installed side by side and temporarily bundled by the pipe bundling member 1 while simultaneously unwinding the plurality of pipes 20 from the supply drum 31. In this case, the pipe bundling member 1 is bent with the connecting portion 4 as a base point, and the extending direction of the rib 3 in each single member 11 is directed toward the corresponding supply drum 31, so that the arrangement interval and the supply of the rib 3 are supplied. The difference between the arrangement intervals of the drums 31 can be eliminated, and the temporary binding work can be performed smoothly. In addition, the plurality of pipes 20 temporarily bundled while being unwound from the supply drum 31 in this way are wound up by the rotating drum 30 (not shown in FIG. 9), whereby a plurality of temporarily bundled pipes as shown in FIG. The rotating drum 30 around which the pipe 20 is wound can be easily prepared.

  Further, the pipe bundling member 1 can be easily detached from the pipe 20 by pulling the pipe 20 from between the ribs 3 by a manual operation by an operator or the like. Furthermore, for example, when the pipe 20 is permanently installed on the fixing member 40 as shown in FIG. 10, the labor of pulling out the pipe 20 from between the ribs 3 by an operator or the like can be omitted. That is, in such a case, as shown in FIG. 10 (a), the pipe 20 is fitted into the fixing member 40 with the pipe binding member 1 attached, and the rib 3 is attached as shown in FIG. 10 (b). By bringing it into contact with the fixing member 40, the pipe binding member 1 can be easily detached from the pipe 20. If it does in this way, the working efficiency at the time of carrying out the main installation of the pipe 20 can be improved significantly.

(Other embodiments)
The present invention is not limited to the embodiments, and can be implemented in various other forms without departing from the spirit or main features thereof.

  In the above-described embodiment, the pipe binding member 1 is configured by connecting a plurality of the single members 11. However, the present invention is not limited to this, and the single single member 11 itself is connected to the pipe binding member without connecting the single members 11. It may be used as 1.

  In the above-described embodiment, the four ribs 3 project from each single member 11 so that the three pipes 20 can be bundled. However, the present invention is not limited to this. For example, each single member 11 has three ribs 3. The two pipes 20 may be bundled by protruding so that five or more ribs 3 protrude from each single member 11 so that four or more pipes 20 can be bundled. .

  Furthermore, in the said embodiment, although the connection part 4 was comprised by the rod-shaped 1st connection part 14 and the 2nd connection part 15 which has the hole 15a, it is not restricted to this, For example, the pivot which has a spherical outer peripheral surface You may comprise a pivot connection part by a part and the bowl-shaped seat which has a hemispherical surface. Also with such a pivot connecting portion, the pipe bundling member 1 can be bent along the longitudinal direction, and the pipe bundling member 1 can be curved so that the longitudinal direction of the single member 11 is radial. It becomes.

  Moreover, in the said embodiment, while curving the front-end | tip part of the rib 3 in circular arc shape, a part of rib 3 is connected with the guide part 16, but it is not restricted to this, For example, as shown in FIG. You may make it provide the rib 13 of a shape which follows an external shape. In this way, since the pipe 20 fits firmly between the ribs 13, it is possible to suppress the pipe binding member 1 from sliding along the pipe 20.

  Furthermore, as shown in FIG. 12, a detachable attachment 17 may be attached to the single member 11. In this way, for example, during work, the workability can be improved by attaching the attachment 17 to the single member 11 and using the attachment 17 as a work handle as shown in FIG. . On the other hand, for example, when winding around the rotating drum 30, the winding work can be smoothly performed by removing the attachment 17 from the single member 11 as shown in FIG. Note that the attachment 17 that can be attached to and detached from the single member 11 is easily realized by, for example, forming an engaging portion and an engaged portion (not shown) that form a pair with each other on the attachment 17 and the single substrate 12. be able to.

  As described above, the above-described embodiment is merely an example in all respects and should not be interpreted in a limited manner. Further, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.

  According to the present invention, since it can be easily removed from the pipe and the economic efficiency can be improved, it is extremely useful when applied to a pipe bundling member for temporarily bundling a plurality of pipes.
