Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a pipe support band, and more specifically, a pipe to be moved due to axial expansion and contraction due to heat change, water hammer phenomenon, etc. And a pipe support band supported by a low friction coefficient member disposed in the pipe support so as to be in contact with each other in a V shape.

[Prior Art] Conventionally, as pipe support bands for supporting pipes that move in the axial direction due to axial expansion and contraction due to heat change, water hammer phenomenon, etc.
Those described in JP-A-62-37684 and JP-B-51-1527 are known.

[Problems to be solved by the invention] In Japanese Utility Model Publication Nos. 59-42377, 59-42378, and 62-37684, a roller formed in a drum shape (hyperbolic shape) corresponding to the diameter of the pipe is used. By supporting the pipe from below, the pipe can be moved in the axial direction, and the bulging of both ends of the drum-shaped roller restricts the movement of the pipe in the lateral direction to stabilize the pipe support. Has been done.

Also, in Japanese Utility Model Publication No. 51-1527, two cone-shaped rollers are installed side by side so that the tops of the rollers are inward, and the shafts are supported so that the pipe is slanted from the lower side to the inner side. A technique for stabilizing the pipe support by supporting it in the opposite direction and regulating the lateral movement is also disclosed.

However, when the pipe is supported by the roller as described above, the roller formed in the hourglass shape or the conical shape has to be cast or cut, so that the formation is not easy and the mass productivity is low. Moreover, since the roller is extremely expensive, there is a drawback that the cost of the piping equipment increases when the piping support band supported by such a roller is used for the piping equipment.

Further, in the case of the hourglass-shaped roller, it is necessary to prepare rollers having various hyperbolic surface shapes of various sizes according to the diameter of the pipe to be supported, which not only increases the cost but also makes inventory management difficult. It has the drawback of

Furthermore, in the case of the two cone-shaped rollers,
Since the weight of the pipe acts in a direction to spread the two cone-shaped rollers outward, there is a drawback that the roller shaft is easily disengaged.

[Object of the Invention] Therefore, an object of the present invention is to arrange a pipe that moves in the axial direction by disposing a low friction coefficient member such as ethylene tetrafluoride resin on both sides of a V-shaped pipe support portion. An object is to provide a pipe support band that can be stably supported at low cost.

[Means for Solving the Problems] The inventor of the present invention has conducted intensive studies to achieve the above object, and as a result, has arrived at the present invention.

That is, the pipe support band according to the present invention is a pipe support band in which a pipe is supported by a low friction coefficient member such as tetrafluoroethylene resin. The band body and the pipe support portion are round bars having a substantially circular cross section. The engaging part with the band support has any one of the following constitutions (1) to (4), the pipe supporting part is formed in a V shape, and both sides of the V shape have a low friction coefficient. It is characterized in that the members are arranged so as to be substantially tangent to the pipe.

(1) Both ends of the pipe support portion are extended to the side facing the pipe support portion via two legs that are pipe holding portions, and extend from both of the leg portions to be polymerized to form the polymerized portion. Is crushed into a flat plate shape and has a through hole penetrating the overlapped portion.

(2) Both ends of the pipe support portion are extended to the side facing the pipe support portion via two leg portions which are pipe holding portions, and extend from both of the leg portions and face each other at a substantially right angle. The rising portion is crushed into a flat plate shape, and has a through hole penetrating the opposing rising portions.

(3) Both ends of the pipe support portion are extended to two sides facing the pipe support portion via two leg portions that are pipe holding portions, and extend from both of the leg portions to be polymerized to form the polymerized portion. Are bent in an annular shape so that they substantially coincide with each other.

(4) Both ends of the pipe support portion are extended in directions away from each other, and both end portions are crushed into a flat plate shape, and the two leg portions standing on the floor pedestal are inserted into the flat plate portion. Configuration with possible through holes.

[Operation] In the pipe support band according to the present invention, the pipe support portion is formed in a V shape, and the low friction coefficient member such as tetrafluoroethylene resin is provided on both sides of the V shape pipe support portion. Since it is arranged so as to be substantially tangential to the pipe, the pipe can be supported so as to be movable in the axial direction without using a high-cost roller, and the pipe can be supported from both diagonally lower sides. Since the weight of the pipe acts in a direction perpendicular to both sides of the V-shaped pipe support portion, the pipe can be stably supported so as to be movable in the axial direction without being displaced laterally.

Conventionally, the technology of using a low friction coefficient member is Jpn.

No. 1, 58-142470, 58-161281, 58-165385,
Although known as No. 60-10979, No. 60-91871, No. 60-138084, etc., since these techniques support the pipe from directly below, the mobility of the pipe was not sufficient.
Therefore, it is necessary to use an expensive member as the low friction coefficient member. The present invention can solve this problem.

Further, since the band body and the pipe support portion are formed of a round bar having a substantially circular cross section, it is possible to manufacture the same material with which quality control is easy.

Therefore, it becomes possible to provide a band for supporting the pipe that moves in the axial direction, which was conventionally expensive, at an extremely low cost, and if a heat-shrinkable cylindrical tube is used as the low friction coefficient member, it is possible to perform mass production. A highly flexible pipe support band can be obtained at low cost.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

The drawing shows a mode in which the engaging portion has the second configuration, FIG. 4 shows a mode in which the engaging portion has the third configuration, and FIG. 6 shows a mode in which the engaging portion has the fourth configuration. FIG. 7 shows a mode in which the band main body has another structure, and FIG. 5 is a partial plan view of the engaging portion having the third structure shown in FIG. 4, and FIG.
The figure is a front view showing a reference example.

In the figure, reference numeral 1 denotes a band main body composed of a round bar having a substantially circular cross section, and the band main body 1 mainly comprises a pipe supporting portion 2 for supporting a pipe P and the band main body 1 on a floor or a ceiling.
And an engaging portion 10 that engages with a roller band support tool (not shown) for attaching the. Band body 1
Is made of metal such as steel or stainless steel, hard synthetic resin, etc.
It is made of the same material as various known pipe support bands.

The pipe support portion 2 is formed in a V shape as shown in the figure, and low friction coefficient members 3 and 3 made of tetrafluoroethylene resin or the like are provided on both sides of the pipe support portion 2 to be substantially tangential to the pipe P, respectively. It is arranged so that. As the low friction coefficient member 3.3,
Any material such as PVC, cross-linked polyolefin, olefin resin, PET, silicone resin, fluororesin may be used, preferably tetrafluoroethylene resin, which may be produced by any of tube method and sheet method, Moreover, the structure may be either a single layer or a multilayer. The low friction coefficient members 3.3 are
A cylindrical tube having a diameter slightly larger than the diameter of the pipe support portion 2 is inserted into the pipe support portion 2 and then heat-shrinked to fix the pipe support portion 2. As a method of fixing, in addition to fixing by heat contraction, an adhesive may be used, a groove may be formed in the portion of the pipe supporting portion 2 and fitted into the groove, or locked by another member. Good. The low friction coefficient member 3 is not limited to the illustrated cylindrical tube as long as it is arranged in the pipe support part 2 and can support the pipe P so as to be movable in the axial direction. It may be fixed to the surface of the second pipe P that contacts the pipe P, or at least the portion of the pipe support portion 2 in contact with the pipe P (or the entire pipe support portion 2) may be coated with a resin having a low friction coefficient. It is possible to form the band body 1 itself including the pipe support portion 2 with a member having a low friction coefficient, but at present, in terms of cost, it does not reach the above-mentioned other configurations.

As described above, the pipe support portion 2 is formed in a V shape, and the low friction coefficient members 3 and 3 are arranged on both sides of the pipe support portion 2 so as to be substantially circumscribed to the pipe P, so that the cost is high. Since the pipe P can be supported so as to be movable in the axial direction without using a certain roller, and the pipe P is supported from diagonally below, the weight of the pipe P is relative to both sides of the V-shaped pipe support portion 2. Since the pipes P work in the right-angled direction, the pipe P can be stably supported so as not to be displaced in the lateral direction and movable in the axial direction.

Next, the structure of the engaging portion 10 of the pipe support band according to the present invention will be described.

The engaging portion 10 of the band body 1 that engages with the roller band support tool (not shown) mainly has the following four configurations, and those having the first to third configurations are suspension type pipes. The present invention is applied to a support band, and the one having the fourth configuration is applied to a floor-standing type pipe support band. Hereinafter, description will be made step by step.

First, the engaging portion 10 having the first configuration will be described with reference to FIG.

The engaging portion 10 having the first configuration is such that both ends of the pipe supporting portion 2 extend to the side facing the pipe supporting portion 2 via the two leg portions 4 serving as pipe holding portions. Have polymerized with each other,
The overlapped portion 11 is crushed into a flat plate shape, and a through hole 10A is formed in the overlapped portion 11 through the overlapped portion 11. This through hole 10A is provided with bolts and nuts (not shown) for engaging the roller band support.
For engaging.

In addition, the pipe support portion 2 is provided with a pipe shaft centered on the shaft 2B of the valley 2A in order to open the engaging portion 10 between the legs 4 and 4 which are the pipe holding portions and to pass the pipe P. It is configured to expand in the orthogonal direction. The structure of the valley portion 2A is not limited to this, and is fitted by the locking plate 5 as shown in FIG.
The pipe may be expanded in the axial direction of the pipe, or the screw member 6 as shown in FIG. 3 may be expanded or detachable.

Next, the engaging portion 10 having the second configuration will be described with reference to FIG.

Both ends of the pipe support portion 2 extend to the side facing the pipe support portion 2 via two leg portions 4 and 4 which are pipe holding portions and face each other and rise up at a substantially right angle. Cage, this rising 12
・ 12 is a flattened flat surface, and the upright parts facing each other
A through hole 10A is formed in each of 12 and 12 so as to penetrate the rising portion 12 and 12. By engaging a bolt, a nut or the like (not shown) in the through hole 10A, the roller band supporting tool is engaged with the engaging portion 10 composed of the rising portions 12 and 12.

The configuration shown in FIG. 3 has the same configuration as that of FIG. 2 except that the configuration of the valley portion 2A of the pipe support portion 2 is different. That is,
The engaging portion 10 in FIG. 3 has the second configuration.

Next, the engaging portion 10 having the third configuration will be described with reference to FIG.

Both ends of the pipe support portion 2 extend on the side facing the pipe support portion 2 via the two leg portions 4 serving as pipe holding portions and are bent in an annular shape (see FIG. 5). (See the plan view of the engaging portion 10 portion), the annular portions 13 are configured such that the through holes 10A formed by being bent in an annular manner communicate with each other. By engaging a bolt, a nut or the like (not shown) with the through hole 10A, the roller band support is engaged with the engaging portion 10 formed by the annular portions 13. The annular portions 13 may be formed by simply bending both ends of the legs 4. However, it is preferable that the annular portions 13 be bent and crushed into a flat shape without rattling when fixed to the roller band support.

Next, the engaging portion 10 having the fourth structure will be described with reference to FIG.

Both ends of the pipe support portion 2 extend in directions away from each other, and the extended both ends are flattened to form flat plate portions 14. A through hole 10A is formed in the flat plate portions 14 and 14, and leg portions 21 and 21 erected on the floor pedestal 20 are fixed to the through hole 10A by nuts 22 and the like.

Incidentally, in the case of the one having the fourth structure shown in FIG. 6, a guide member shown by an imaginary line 23 may be added, or a leg part shown by an imaginary line 24 may be added.
A guide member composed of a U-bolt integrally formed with 21.21 may be added. When the guide member 24 made of a U-bolt is used, the lower ends of the legs 21 are detachably attached to the floor pedestal 20 (not shown).

Further, in the case of the floor-standing type, as shown in FIG. 7, both ends of the pipe supporting portion 2 and the leg portions 21 and 21 are integrally configured to form a floor-standing pedestal.
May be fixed at 20.

FIG. 8 shows, as a reference example, a mode in which the band body 1'and the pipe supporting portion 2 are formed by separate members.

[Advantages of the Invention] According to the present invention, the pipe support portion is formed in a V shape, and low friction coefficient members such as tetrafluoroethylene resin are attached to the pipe on both sides of the V shape pipe support portion. Since it is arranged so as to be substantially tangential to the pipe, the pipe can be supported so as to be movable in the axial direction without using a high-cost roller, and as a low friction coefficient member, for example, heat shrinkage is possible. By adopting a flexible cylindrical tube, it is easy to manufacture and it is possible to achieve cost reduction.

Further, since the pipe is supported diagonally from both lower sides, the weight of the pipe acts in a direction perpendicular to both sides of the V-shaped pipe support portion, so that the pipe does not shift in the axial direction and can be moved in the axial direction stably. In addition to the conventional support from directly underneath, it is possible to obtain sufficient pipe mobility by means of an inexpensive low-friction-coefficient member and to further reduce the cost.

Furthermore, since the band main body and the pipe support portion are formed of a round bar having a substantially circular cross section, it is possible to obtain a pipe support band with higher mass productivity.
