Description

The present invention relates to a pipe support attachment that is used together with a pipe support when supporting various pipes in the form of a suspension band or a vertical band.

In air conditioning equipment construction and sanitary equipment construction, various pipes are used according to the purpose and purpose, and when classified by material, they are roughly classified into metal pipes and resin pipes.

For example, a lining steel pipe whose inner surface is coated with polyethylene or hard polyvinyl chloride, or a resin pipe such as a hard polyvinyl chloride pipe or a polyethylene pipe is used for the water supply pipe, and a stainless steel pipe or heat resistant pipe is used for the hot water supply pipe. Hard polyvinyl chloride lining steel pipe is used.

When installing these pipes in a building, if it is a horizontal pipe, it is hung from the ceiling or upper floor slab with a hanging band, and if it is a rising pipe, it is fixed to the wall with a vertical band.

The suspension band and the vertical band are opposed to each other from a pipe insertion portion configured so that a pipe can be inserted inside the strip-shaped steel material by bending it in an annular shape in the out-of-plane direction, and from each end of the pipe insertion portion. It is composed of a pair of connecting parts extending in the radial direction so as to support the pipe using these hanging bands and vertical bands, on the ceiling surface or above between the pair of connecting parts. By sandwiching the lower end of the connector fixed to the lower surface of the floor slab or the tip of the connector fixed to the wall surface, inserting the pipe into the pipe insertion part, and then inserting the bolt into the pair of connection parts and tightening. The pipe is suspended from the ceiling or upper floor slab, or fixed to the wall.

Here, the weight of the pipe always acts as a vertical load on the pipe insertion part made of strip-shaped steel material, or the inertial force during an earthquake acts as a horizontal load, while the reaction force acts on the peripheral surface of the pipe. Although it works, in order to reduce the manufacturing cost, the width of the steel material must be limited to about 25 mm.

Therefore, if the action surface of the reaction force from the pipe insertion portion is concentrated in a narrow range of the pipe, and as a result, the strength of the pipe is lowered due to corrosion or the like, the pipe may be broken. Further, since the pipe insertion portion is formed by bending a strip-shaped steel material out of the plane, the pipe insertion portion is provided with stiffening ribs for preventing so-called springback in the circumferential direction. Since the unevenness appears as a ridge on the outer peripheral side and as a groove on the inner peripheral side, the load acting surface is further reduced, and the above-mentioned stress concentration becomes more remarkable.

By the way, when the pipe is a metal pipe, a steel material coated with an electric insulating material is used as a pipe insertion part in order to prevent electrolytic corrosion, but conventionally, the coating of the electric insulating material is mainly used. Since it is performed by dipping, the above-mentioned stiffening ribs are only covered with an electric insulating material along the unevenness, and the above-mentioned grooves still appear on the inner peripheral side, and the load acting surface due to the grooves remains visible. The problem of decline is not solved at all.

Showa Corporation, [online], [Search on December 8, 1st year of Reiwa], Internet <URL: https://www.showa-cp.jp/products-own/sleeperl/> Showa Corporation, [online], [Searched on December 13, 1945], Internet <URL: https://www.showa-cp.jp/products-own/boushin/>

In order to solve such a problem, the applicant has provided a load transmission means made of a resin material arranged between the pipe insertion part made of a strip-shaped steel material and the pipe so that the load is transmitted between them. In addition to the provision, a pipe support has been developed in which the load transmitting means is formed on the inner peripheral side thereof so that unevenness does not appear in the cross section including the material shaft of the pipe.

According to such a pipe support, the load transmitting means comes into contact with the peripheral surface of the pipe on the inner peripheral side thereof with a sufficient working area regardless of the cross-sectional shape of the pipe insertion portion. The force, that is, the reaction force to the pipe's own weight and the pipe's inertial force during an earthquake, acts on the pipe in a dispersed state, thus reducing the shear stress generated in the pipe, concentrating the stress on the pipe, and eventually causing breakage. Is prevented.

However, in the above-mentioned pipe support, it is desirable to manufacture the strip-shaped steel material by injection molding with the portion corresponding to the pipe insertion portion as an insert. However, with such a method, the steel material is positioned with respect to the mold. For example, there is a problem that it takes time and cost to manufacture, and when the pipe insertion part is expanded so that the pair of connecting parts are separated and the pipe is passed inside the pipe insertion part, a large bending moment acts on the load transmission part and the load is applied. There was a problem that the transmission part could be damaged.

Further, Non-Patent Document 1 discloses a pipe support tool in which a plurality of heat insulating materials are arranged so as to surround a pipe, and the heat insulating material is surrounded by a strip-shaped steel material and suspended. Until the tightening work is completed, multiple heat insulating materials must be pressed against the outer peripheral surface of the pipe so that they do not separate from each other, shift from each other, or fall, which requires multiple workers. In addition to causing problems such as complicated work and time-consuming work, the problem of workability becomes more prominent because the work is often performed at a high place with a hanging band or a vertical band.

In addition, when hot and cold water flows through the pipe, especially when cooling water flows, the condensed water may corrode metal products or drip downward, causing various problems. In addition to the need to wrap a heat insulating material from the viewpoint of preventing heat loss, it is also necessary to provide heat insulation between the strip-shaped steel material that constitutes the suspension band or vertical band and the pipe at the pipe fixing point. However, in the piping support described in Non-Patent Document 1, since a plurality of heat insulating materials are formed of hard urethane foam, it is difficult for the hard urethane foam to have both a heat insulating function and a load distribution function sufficiently. I was having a problem.

In addition, various mechanical vibrations are transmitted from the drive source to the piping, and the pressure pulsation of the liquid pumped from the pump acts on the piping. When the frequency matches the natural frequency of the piping system, the piping vibrates significantly due to resonance. However, as a result, the pipes and the pipe supports that fix them may be damaged. Therefore, it is necessary to provide vibration isolation between the strip-shaped steel materials constituting the suspension band or the vertical band and the pipes. However, in the pipe support described in Non-Patent Document 2, since the anti-vibration rubber is pre-mounted on the strip-shaped steel material, if the pipe support is arranged so as to surround the pipe, the tip of the anti-vibration rubber is installed during the installation. May come into contact with the outer peripheral surface of the pipe and cause residual deformation of the anti-vibration rubber at the end of installation, or unexpected residual stress may be generated in the anti-vibration rubber. The transmission function may be hindered, or the anti-vibration rubber may not be able to exert its original anti-vibration function.

In addition, in the piping support described in Non-Patent Document 2, the vibration-proof rubber produced in a straight shape is curved after production and attached to a strip-shaped steel material, so that the softness is commensurate with the rubber. There was no choice but to manufacture anti-vibration rubber, which caused a problem that it was inherently difficult to adjust the rigidity suitable for anti-vibration.

The present invention has been made in consideration of the above-mentioned circumstances, and it is possible to reduce the manufacturing cost as compared with the case of insert molding, and to secure the same workability as in the case of insert molding at the time of mounting on the pipe. It is an object of the present invention to provide an attachment for supporting a pipe which can be used.

Another object of the present invention is to provide a pipe support attachment capable of enhancing heat insulation and vibration isolation in addition to these.

In order to achieve the above object, as described in claim 1, the pipe support attachment according to the present invention is a hanging band that supports pipes by connecting to a building frame such as a slab, a ceiling, or a wall. , A pipe support attachment used in combination with a pipe support such as a vertical band.

The load transmission unit is composed of a plurality of load transmission blocks juxtaposed so as to surround the pipe along the circumferential direction of the pipe, and the plurality of load transmission blocks are connected in a form surrounding the pipe. It is configured to be free.

Further, the pipe support attachment according to the present invention is composed of the plurality of load transmission blocks, each of which has a semi-cylindrical shape and is arranged adjacent to each other in a form of being hugged by the pipe. The fitting grooves are provided on the outer peripheral surfaces of the two side blocks, and the two side blocks are provided with the inner peripheral surfaces thereof serving as the piping side contact surface so that the piping is sandwiched between them. Is configured to be a contact surface and connected to each other.

Further, in the pipe support attachment according to the present invention, of the plurality of load transmission blocks, one of the two load transmission blocks adjacent to each other in a state of surrounding the pipe has a magnetic material, and the other has a magnetic material on the magnetic material. It is an arrangement of metal objects to be worn.

Further, as described in claim 4, the pipe support attachment according to the present invention includes a hanging band, a vertical band, or the like that supports the pipe by connecting to a building frame such as a slab, a ceiling, or a wall. A pipe support attachment used in combination with a pipe support, in which a pipe side contact surface that contacts the outer peripheral surface of the pipe is provided on the inner peripheral side, and a part of the pipe support is fitted to the outer peripheral side. The load is provided with a load transmission portion in which a joint groove is formed so that a load can be transmitted between the pipe and the pipe support through the pipe-side contact surface and the fitting groove. The transmission unit is composed of a plurality of load transmission blocks that are connected to each other along the circumferential direction of the pipe and can be arranged side by side so as to surround the pipe.

Further, the pipe support attachment according to the present invention is composed of the plurality of load transmission blocks, each of which has a semi-cylindrical shape and can be arranged in a shape of being coupled to the pipe, and the two sides. The fitting grooves are provided on the outer peripheral surfaces of the square blocks, and the two side blocks are provided with the inner peripheral surfaces thereof serving as the piping side contact surface so that the piping is sandwiched between the two lateral blocks. It is configured to be a contact surface.

Further, in the pipe support attachment according to the present invention, the plurality of load transmission blocks are each formed of a thermoplastic elastomer.

Further, in the pipe support attachment according to the present invention, the load transmitting portion is arranged so that gaps extending along the material axis direction of the pipe to at least near both ends of the load transmitting portion are discretely arranged along the circumferential direction of the pipe. It is configured to be.

Further, the pipe support attachment according to the present invention has the load transmitting portion configured so that both ends of the gaps are closed.

Further, in the pipe support attachment according to the present invention, the gaps are formed so that their cross-sectional shapes are hexagonal, and they are arranged close to each other via a hexagonal partition wall.

Further, the pipe support attachment according to the present invention is dispersedly arranged in the circumferential direction so as to extend toward the material axis of the pipe in the load transmission portion, and each tip surface serves as the pipe side contact surface as the outer periphery of the pipe. A plurality of protrusions formed so as to be in contact with each other are provided.

Further, in the pipe support attachment according to the present invention, at least the protrusions of the load transmitting portion are formed of a thermoplastic elastomer having a vibration absorbing function.

[Action according to the present invention]
In the pipe support attachment according to the present invention, a pipe-side contact surface that contacts the outer peripheral surface of the pipe is provided on the inner peripheral side of the load transmitting portion, and is connected to the pipe via the pipe-side contact surface. On the outer peripheral side, a fitting groove into which a part of the pipe support is fitted is formed, and the load between the pipe support and the pipe support is formed through the inner surface of the groove of the fitting groove. Communication is being carried out.

In this way, by appropriately securing the area of the contact surface on the pipe side on the inner peripheral side, the load is transmitted to and from the pipe in a dispersed state, and on the outer peripheral side, the inner surface of the fitting groove is formed. The load is reliably transmitted to and from the pipe support via the pipe support, and the movement of the pipe support attachment along the material axis direction of the pipe is restricted.

Therefore, even in a situation where a vibration load is applied from the pipe, there is no concern that the pipe support attachment may be displaced in the direction of the pipe material axis or fall out from between the pipe and the pipe support, and the above-mentioned load transmission function is eliminated. Is surely maintained, and thus, it is possible to prevent the stress concentration of the pipe in a more economical form without manufacturing the pipe so as to be integrated with the pipe support.

In addition, when the pipe is manufactured integrally with the pipe support, the pipe insertion part is expanded so that the pair of connecting parts are separated from each other during the pipe support work, and the pipe is passed through the inside thereof, so that the load is transmitted. A large bending moment may also act on the portion, which may cause damage to the load transmitting portion. However, in the pipe support attachment according to the present invention, the load transmitting portion is formed along the circumferential direction of the pipe. Since it is composed of a plurality of load transmission blocks juxtaposed so as to surround the pipe, there is no concern that the load transmission block will be damaged due to a bending moment generated during the pipe support work.

In order to fix a pipe to a building frame using the pipe support attachment according to the present invention, first, a plurality of load transmission blocks are arranged along the circumferential direction of the pipe so as to surround the pipe, and then. The pipe support is placed in the pipe while the pipe support is fitted into the fitting groove formed in the load transmission block, and then the pipe support is placed on the ceiling or upper floor via an appropriate connector. Although it is fixed to a building frame such as a slab or a wall, the pipe support attachment according to the present invention can be independently placed in advance on the pipe, so that the pipe support attachment can be used until the fixing work by the pipe support is completed. You no longer have to be careful not to drop or fall off the pipe.

[Basic configuration of load transmission unit]
The plurality of load transmission blocks may be arranged side by side so as to surround the pipe along the circumferential direction of the pipe, and may be configured so as to be connectable in a shape surrounding the pipe (hereinafter, first). (Structure), it may be configured so that it is connected to each other via a hinge along the circumferential direction of the pipe and can be juxtaposed so as to surround the pipe (hereinafter, the second configuration).

Here, in the first configuration, the state surrounding the pipe is held by the connection, in other words, the contact surface on the pipe side provided in the load transmission portion is preferably the outer peripheral surface of the pipe due to the force due to the connection. It is essential that the load transmission blocks continue to be in contact with the outer peripheral surface without being separated from the pipe, and at least be prevented from being separated from each other so as to fall off from the pipe. It is optional if they are connected to each other.

On the other hand, in the second configuration, it is essential that the pipes are connected to each other via a hinge along the circumferential direction of the pipes and can be juxtaposed so as to surround the pipes, and the ends on the unconnected side. By rotating multiple load transmission blocks around the hinge so that the part opens, the pipe can be put in the inserted state, while the end of the unconnected side with the pipe inserted. It is indispensable to be able to arrange the pipes in a state of surrounding them by rotating multiple load transmission blocks around the hinges so that the pipes are closed. It is not always necessary to do so, and instead of the connecting force, an external force, for example, the case where the pipe is kept surrounded by the pressing force of the worker is also included.

By the way, in the case of holding by the pressing force of the worker, it is necessary to take some care so that the attachment for supporting the pipe does not come off or fall from the pipe, but multiple load transmission blocks are attached to each other along the circumferential direction of the pipe. Since they are connected, the work load when installing the pipes is still reduced compared to the past.

[Specific configuration of the load transmission unit according to the first configuration]
The number of the plurality of load transmission blocks according to the first configuration is arbitrary, and the shape of each is not limited, but the two sides are arranged adjacent to each other in a semi-cylindrical shape and hugged by the pipe. The two side blocks are composed of square blocks, and the above-mentioned fitting grooves are provided on the outer peripheral surfaces of the two side blocks, and the inner peripheral surfaces of the two side blocks serve as contact surfaces on the pipe side to sandwich the pipes. A typical example is a structure in which the facing end faces serve as contact surfaces and are connected to each other.

As long as the plurality of load transmission blocks are configured so as to be connectable so as to surround the pipes, are they separated from each other and arranged so as to surround the pipes and connected to each other, or, for example, a hinge or the like. It is arbitrary whether the pipes connected via the above are arranged so as to surround the pipes and then interconnected, and the configuration for connecting is also arbitrary.

As a specific configuration for connection, among the load transmission blocks adjacent to each other, one is provided with a locking portion and the other is provided with a claw locked to the locking portion, one is a recess, and the other is a recess. It is possible to adopt a configuration in which convex portions to be fitted to the concave portions are provided, or a configuration in which an adhesive sheet such as double-sided tape is attached to one side and an adhesive surface to which the adhesive sheet adheres is provided on the other side. Is.

Here, if it is an adhesive structure, it is difficult to redo the connecting work, but if the structure is provided with a magnetic material on one side and a metal object magnetically attached to the magnetic material on the other side, it is easy to manufacture and the connecting work is performed. Can be redone.

[Specific configuration of the load transmission unit according to the second configuration]
The number of the plurality of load transmission blocks according to the second configuration is arbitrary, and the shape of each is not limited, but each of the plurality of load transmission blocks has a semi-cylindrical shape and can be arranged in a shape of being coupled to the pipe. It is composed of blocks, and the fitting grooves are provided on the outer peripheral surfaces of the two side blocks, respectively, and the pipes are sandwiched between the two side blocks with their inner peripheral surfaces serving as the pipe-side contact surfaces. A typical example is such that the facing end faces are configured to be contact surfaces with each other.

The hinge can be appropriately selected from plastic hinges or plastic hinges widely used in plastic products.

[Configuration common to the first configuration and the second configuration]
The specific forming material is arbitrary as long as the plurality of load transmission blocks are configured so as to be interposed between the pipe and the pipe support as a load transmission portion so that the load can be transmitted to both of them. It is desirable to use a resin material with excellent deformation performance, especially a thermoplastic elastomer, as the forming material.

[Structure that enhances the heat insulation of the load transmission part]
The load transmitting portion can be configured so that the gaps extending along the material axial direction of the pipe to at least near both ends of the load transmitting portion are discretely arranged along the circumferential direction of the pipe.

In this way, by appropriately setting the material for forming the load transmitting portion and the discrete arrangement form of the voids, it is possible to form a heat insulating space having a sufficient volume in the load transmitting portion while ensuring the load transmitting function. It is possible to provide a heat insulating performance equal to or higher than that of a heat insulating material using a conventional rigid urethane foam in a more economical form.

The void formed in the load transmitting portion can be formed of a hole (circular hole) having a circular cross section, such as that formed in a lotus root, but the cross-sectional shape thereof is as long as the required heat insulating performance can be obtained. Is optional.

Here, when the load transmitting portion is configured so that both ends of each void are opened, it is easy to manufacture using a mold during injection molding, but instead, both ends of each void are closed. If the load transmitting portion is configured in the above, the movement of air in and out of the void is blocked, so that the heat insulating performance can be further improved.

In any case, the voids are formed so as to extend at least to the vicinity of both ends of the load transmitting portion so that the heat insulating performance in the load transmitting portion is substantially ensured.

The specific configuration for closing both ends of each gap is arbitrary, but for example, a closing plate having a planar shape similar to that of the end face of the load transmitting portion may be attached to each end face of the load transmitting portion. It is possible.

Further, if the voids are formed so that their cross-sectional shapes are hexagonal and they are arranged close to each other via the hexagonal partition wall, the load transmitting portion is formed of a honeycomb structure. It is possible to form a gap with a cross-sectional area close to the maximum while ensuring a sufficient load transmission function, and the heat insulating performance can be remarkably improved.

Therefore, the thickness of the heat insulating structure can be suppressed more than before, the workability in a narrow place is improved, and the heat insulating material wrapped around the pipe can be overlapped on the pipe support, so that the circumference of the pipe can be overlapped. Even if there is a gap between the heat insulating material and the pipe support attachment, there is no risk of dew condensation occurring in that gap.

[Structure to improve the vibration isolation of the load transmission part]
The load transmitting portions are discretely arranged in the circumferential direction so as to extend toward the material axis of the pipe, and a plurality of protrusions formed so that each tip surface is in contact with the outer peripheral surface of the pipe as a contact surface on the pipe side. Can be provided.

In this way, as described above, the load is transmitted to and from the pipe via the pipe-side contact surface provided on the inner peripheral side thereof, and the load is transmitted to the load-transmitting portion through the fitting on the outer peripheral side. Since the load is transmitted to and from the pipe support through the inner surface of the groove, the pipe support attachment shifts in the material axis direction of the pipe even when a vibration load is applied from the pipe. The above-mentioned load transmission function is reliably maintained without the concern that the pipe or the pipe support may come off.

Therefore, the basic vibration-proof function of the load transmitting portion in which the protrusions are deformed to follow the vibration load is surely exhibited.

The anti-vibration function of the load transmitting portion referred to here is an anti-vibration function by adjusting the rigidity of the protrusions so that the piping support and the pressure pulsation do not resonate. different.

Further, in the conventional piping support for attaching the anti-vibration rubber to the U-band, the anti-vibration rubber formed in a straight shape is curved and set in the U-band in that state. It is necessary to be molded with a softness commensurate with such mounting work, and there are many restrictions on adjusting the rigidity. However, according to the pipe support attachment according to the present invention, the shape of the pipe is attached to the pipe. Since it is manufactured from the beginning, the above problems cannot occur, and the specifications such as the type of material forming the load transmission part, the cross-sectional area of the protrusion, and the length of the protrusion can be freely specified without any restrictions. It can be determined, and the rigidity of the load transmitting portion can be set to a desired size.

Further, in the pipe support attachment according to the present invention, the vibration characteristics of the state of being attached to the pipe support can be clearly determined by a vibration experiment or the like, and this can be reflected in the natural frequency analysis of the pipe system. For example, it is possible to obtain more accurate analysis results.

Here, if at least the protrusions of the load transmitting portion are formed of a thermoplastic elastomer having a vibration absorbing function, the vibration absorbing function of the load transmitting portion can be enhanced.

By the way, in the case of a standard or general-purpose thermoplastic elastomer, the vibration absorption function may not be sufficient, but the function as an elastic spring can be sufficiently exhibited, and the vibration characteristics are examined by a vibration experiment. Even if the vibration absorption function is not sufficient, if the rigidity of the thermoplastic elastomer is set appropriately, the natural frequency of the entire piping system including the piping support can be grasped clearly and with little variation. It is possible to change the frequency of the pressure pulsation so that it does not match the frequency of the pressure pulsation. When it is formed of an elastomer, it is possible to improve the vibration absorbing function in addition to the vibration isolating function by adjusting the rigidity.

Hereinafter, embodiments of the pipe support attachment according to the present invention will be described with reference to the accompanying drawings.

[First Embodiment]
FIG. 1 (a) shows that the pipe support attachment 1 according to the present embodiment is suspended as a pipe support for suspending the pipe 4 to be arranged as a horizontal pipe below the ceiling or the upper floor slab. The assembly perspective view shown together with the band 2, FIG. 2B is an overall perspective view of the pipe support attachment 1, FIG. 2C is an overall perspective view of the suspension band 2, and FIG. 2A is a pipe support attachment. 1 is shown together with the pipe 4, the figure (b) is an exploded perspective view of the pipe support attachment 1, FIG. 3 (a) is a vertical sectional view of the pipe support attachment 1, and the figure (b) is A. A view taken along the line A and FIG. 3C is a cross-sectional view taken along the line BB.

As shown in these figures, the pipe support attachment 1 according to the present embodiment is used in combination with the suspension band 2, and the load is transmitted between the pipe 4 and the suspension band 2. The unit 5 is provided.

Here, the suspension band 2 is formed of a strip-shaped steel material, and radiates from the pipe insertion portion 3 formed in an out-of-plane direction and curved in an annular shape and the opposite end portion of the pipe insertion portion. It is composed of a pair of connecting portions 6 and 6 extending in each direction and facing each other, and the pair of connecting portions are connected to a hanging bolt or the like while utilizing the bolt insertion holes 7 and 7 formed in the connecting portion. By connecting to the ceiling surface or the lower surface of the upper floor slab via a tool (not shown), the pipe 4 inserted in the inner space of the pipe insertion portion 3 can be suspended.

A stiffening rib 8 for preventing so-called springback is provided in the pipe insertion portion 3 in the circumferential direction, and the unevenness thereof appears as a ridge 9 on the outer peripheral side and as a groove 10 on the inner peripheral side.

Further, in the pipe insertion portion 3, a cross-section defect portion 15 formed of an opening is provided at a portion located on the opposite side of the pair of connecting portions 6 and 6, that is, at a position near the lowermost end, and the connecting portions 6 and 6 are provided. The opening and closing operations of the pipe insertion portions 3 along the directions away from each other can be easily performed.

The load transmitting portion 5 is composed of two side blocks 5a and 5b, each of which has a semi-cylindrical shape and is arranged adjacent to each other so as to be engaged with the pipe 4, and these are arranged along the circumferential direction of the pipe 4. The pipes can be arranged side by side so as to surround the pipes and connected in that form.

The side blocks 5a and 5b are each formed by injection molding using a thermoplastic elastomer having excellent deformation performance as an injection material.

In the side blocks 5a and 5b, the inner peripheral surfaces 12a and 12b of the side blocks 5a and 5b are in contact with the outer peripheral surface of the pipe 4 as the pipe side contact surfaces, respectively, in a state where the pipe 4 is sandwiched between them. At the same time, the end faces 13a and 13a (one of the facing end faces) formed at each end of the side block 5a and the end faces 13b and 13b (the other of the facing end faces) formed at each end of the side block 5b are in contact with each other. Since it becomes a surface and can be connected to each other, the load is transmitted to and from the pipe 4 via the inner peripheral surfaces 12a and 12b which are the contact surfaces on the pipe side.

On the other hand, on the outer peripheral surfaces of the side blocks 5a and 5b, fitting grooves 18a and 18b in which the pipe insertion portion 3 is fitted are provided in the hanging band 2, respectively, and the hanging band 2 is provided through the fitting groove.

It may be composed of the bottom block 101a and the top block 101b arranged in.

In the case of the modified example shown in the figure, a fitting groove 102a is formed in the bottom block 101a, and a fitting groove 102b is formed in the top block 101b.

Further, in the present embodiment, the interconnecting means of the side blocks 75a and 75b is bonded or fitted, but instead, as shown in FIG. 11, a magnetic material is formed on the end faces 13a and 13a of the side blocks 75a. The magnet sheet 51 may be configured such that bolts 52 and 52, which are metal objects magnetically attached to the magnet sheet 51, are embedded in the end faces 13b and 13b of the side block 75b, respectively.

Commercially available products can be selected.

In order to suspend the pipe 4 by using the pipe support attachment 141 according to the present embodiment, the side blocks 145a and 145b are arranged so as to surround the pipe 4 as in the first and second embodiments. After connecting to each other in the form, the suspension band is placed on the outside of the pipe support attachment 141 so that the pipe insertion portion 3 of the suspension band 2 is fitted into the fitting grooves 18a and 18b of the side blocks 145a and 145b, respectively. After mounting, the pipe 4 inserted into the inner space of the pipe insertion portion 3 is suspended from the building frame such as the ceiling surface or the lower surface of the upper floor slab.

Here, in order to connect the side blocks 145a and 145b to each other, for example, an adhesive sheet (not shown) is attached to the end faces 13a and 13a of the side blocks 145a before the connection, and this is the side block 145b.

A configuration may be appropriately adopted in which recesses (not shown) to be fitted to the portions are provided, and the side blocks are arranged so that the convex portions fit into the recesses.

Hereinafter, the procedure for suspending the pipe 4 using the pipe support attachment 141 is almost the same as that in the first and second embodiments, and thus detailed description thereof will be omitted here.

In the pipe support attachment 141 according to the present embodiment, the side blocks 145a and 145b are provided with tip surfaces 142a and 142b as pipe-side contact surfaces that come into contact with the outer peripheral surface of the pipe 4, respectively, and the pipe side The load is transmitted to and from the pipe 4 via the contact surface, and on the outer peripheral side, the fitting grooves 18a and 18b into which the pipe insertion portion 3 is fitted are the side blocks 145a and 145b of the suspension band 2. The load is transmitted to and from the suspension band 2 through the fitting grooves 18a and 18b, respectively.

In this way, on the inner peripheral side of the load transmitting portion 145, the width of the load transmitting portion (dimensions along the material axis direction of the pipe 4) is appropriately set to secure the area of the contact surface on the pipe side as much as necessary. By doing so, the load is transmitted to and from the pipe 4 in a dispersed state, and on the outer peripheral side, the load is reliably transmitted to and from the suspension band 2 via the inner surfaces of the fitting grooves 18a and 18b. At the same time, the movement of the pipe support attachment 141 along the material axis direction of the pipe 4 is restricted.

Further, the pipe support attachment 141 according to the present embodiment is provided with a load transmission unit 145 for transmitting a load between the pipe 4 and the suspension band 2, and the load transmission unit is provided as side blocks 145a and 145b. The side blocks 145a and 145b are each provided with a plurality of ridges 143a and 143b discretely arranged in the circumferential direction so as to extend toward the material axis of the pipe 4. The ridges are formed so that their tip surfaces 142a and 142b are in contact with the peripheral surfaces of the pipe 4, respectively.

In this way, the ridges 143a and 143b are deformed in the expansion / contraction direction or the shearing direction so as to follow the vibration load transmitted from the pipe 4, but the main cause of the vibration is, for example, the fluid flowing in the pipe 4. In the case of pressure pulsation, the specifications of the thermoplastic elastomer, which is the material for forming the ridges 143a and 143b, and the three-dimensional shape of the ridges 143a and 143b (dimensions along the circumferential direction of the pipe 4) so as not to resonate with the pressure pulsation. By appropriately selecting the dimensions, height, etc. along the material axis direction of the pipe 4, the compressive rigidity and shear rigidity of the ridge can be adjusted, and the vibration load transmitted from the pipe 4 to the suspension band 2 can be reduced. Can be planned.

As described above, according to the pipe support attachment 141 according to the present embodiment, the load is transmitted to and from the suspension band 2 via the fitting grooves 18a and 18b, so that the pipe 4 Even in a situation where a vibration load is applied from the pipe, there is no concern that the pipe support attachment may shift in the material axis direction of the pipe 4 or fall out from between the pipe 4 and the suspension band 2, and the load transmission function described above is eliminated. Is reliably maintained.

Therefore, it is possible to prevent the stress concentration of the pipe 4 in a more economical form without manufacturing it so as to be integrated with the suspension band 2.

In addition, when it is manufactured integrally with the suspension band 2, the load transmission portion is arranged along the circumferential direction of the pipe insertion portion so as to be integrated with the pipe insertion portion 3 of the suspension band 2. According to the configuration, when the pipe insertion portion 3 is expanded, a large bending moment acts on the load transmission portion integrally arranged with the pipe insertion portion, which may cause damage to the load transmission portion. In the pipe support attachment 141 according to the present embodiment, the load transmitting portion 145 is composed of side blocks 145a and 145b arranged side by side so as to surround the pipe 4 along the circumferential direction of the pipe 4. During the support work, there is no concern that a bending moment is generated in the load transmitting portion 145 and the load transmitting portion is damaged.

Is held, the pipe support attachment 141 can be independently arranged in advance on the pipe 4, and the pipe support attachment 141 comes off or falls from the pipe 4 until the fixing work by the suspension band 2 is completed. You don't have to be careful not to do it.

Further, in the conventional piping support, since the anti-vibration rubber formed in a straight shape must be attached to the inner peripheral side of the U band while being curved, the anti-vibration rubber is softly formed to suit the work. On the other hand, according to the pipe support attachment 141 according to the present embodiment, the side blocks 145a and 145b are formed by injection molding using a thermoplastic elastomer as an injection material. Specifications such as the types of materials forming the square blocks 145a and 145b, particularly those ridges 143a and 143b, the cross-sectional area of the ridges 143a and 143b, and their protruding lengths can be freely specified without any restrictions. Can be determined.

Therefore, it is possible to appropriately adjust the rigidity of the ridges 143a and 143b so that the pressure pulsation of the fluid flowing in the pipe 4 and the pipe system including the pipe and the suspension band 2 do not resonate with each other. It becomes possible to increase.

In the present embodiment, the plurality of load transmission blocks according to the present invention are composed of the side blocks 145a and 145b, but the plurality of load transmission blocks are juxtaposed so as to surround the pipe along the circumferential direction of the pipe. As long as the specific configuration such as the shape and the number of divisions is arbitrary, for example, as shown in FIG. 17, the pipe 4 is sandwiched between the connecting portions 6 and 6 of the suspension band 2 and the opposite side in the figure. It may be composed of a bottom block 171a and a top block 171b arranged in.

In the case of the modified example shown in the figure, a fitting groove 172a is formed in the bottom block 171a, and a fitting groove 172b is formed in the top block 171b.

Further, in the present embodiment, the interconnecting means of the side blocks 145a and 145b is bonded or fitted, but instead, as shown in FIG. 18, a magnetic material is attached to the end faces 13a and 13a of the side blocks 145a. The magnet sheet 51 may be configured such that bolts 52 and 52, which are metal objects magnetically attached to the magnet sheet 51, are embedded in the end faces 13b and 13b of the side block 145b, respectively.

Further, in the present embodiment, the plurality of load transmission blocks according to the present invention are composed of separate side blocks 145a and 145b separated from each other, but instead of this, as shown in FIG. 19, the hinge 62 It may be composed of side blocks 191a and 191b which are connected to each other via the above and are rotatably configured around the hinge. As the hinge 62, a hinge widely used in plastic products can be appropriately selected and adopted.

Since the side blocks 191a and 191b have the same configuration as the side blocks 145a and 145b except that they are connected to each other via a hinge 62, detailed description thereof will be omitted here.

Further, as a connecting means for connecting the side blocks 191a and 191b in a form surrounding the pipe 4, as described above, it is possible to appropriately select and adopt from adhesive, fitting, magnetic bonding and the like. ..

Further, in the present embodiment, the piping support according to the present invention has been described as being applied to the suspension band 2, but it goes without saying that the pipe support can be applied to the vertical band instead.

Further, in the first embodiment, the second embodiment, and the third embodiment, the side blocks 61a, 61a, the side blocks 121a, 121a, and the side blocks 191a, 191a are connected to each other via a hinge 62, respectively. The configuration (FIGS. 6, 12, and 19) is taken as a modified example, and in each of the modified examples, it is essential to adopt a connecting means for connecting the pipe 4 in a surrounding shape. The connecting means may be omitted.

Also in such a configuration, as in each of the modified examples of FIGS. Side blocks 61a, 61a, side blocks 121a, 121a, side blocks 191a, 191a so that the ends on which the end faces 13a, 13b are formed (the ends located below in FIGS. 6, 12, 19) open. Is rotated around the hinge 62 so that the pipe 4 is inserted and the side block 61a is closed so that the end of the unconnected side is closed while the pipe 4 is inserted. , 61a, the side blocks 121a, 121a, and the side blocks 191a, 191a are arranged in a state of surrounding the pipe 4 by rotating the side blocks 191a, 191a around the hinge 62.

However, in the case of this modification in which the connecting means is omitted, an external force, for example, is used instead of the force for connecting so that the state surrounding the pipe 4 is maintained until the suspension band 2 is wound. It is necessary to keep the pipe 4 surrounded by the pressing force of the worker, and therefore some care must be taken to prevent the pipe support attachment from coming off or falling from the pipe 4, but the side block. Since the hinges 62 are connected to the 61a, 61a, the side blocks 121a, 121a, and the side blocks 191a, 191a along the circumferential direction of the pipe 4 via the hinge 62, the work load at the time of pipe installation is conventional. There is no difference in the reduction.
