Description

The present invention relates to a pipe support tool used when supporting various pipes in the form of a hanging 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. Rigid polyvinyl chloride lining steel pipes are used.

These pipes are installed in the building by suspending them from the ceiling or upper floor slab with a hanging band if they are horizontal pipes, and by fixing them to the wall with a vertical band if they are rising pipes. Piping supports such as bands or vertical bands are formed by bending a strip-shaped steel material in an annular shape in the out-of-plane direction so that pipes can be inserted inside the pipe insertion portion and each end of the pipe insertion portion. It is composed of a pair of connecting portions extending in the radial direction so as to face each other, and between the pair of connecting portions, the lower end of the connecting tool fixed to the ceiling surface or the lower surface of the upper floor slab, or By sandwiching the tip of the connector fixed to the wall surface, inserting the above-mentioned pipe into the pipe insertion part, and then inserting a bolt into the pair of connection parts and tightening, the pipe is hung from the ceiling or the upper floor slab. It can be held or fixed to the wall.

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, in the place where the pipe support is provided, between the pipe support and the mounting side member such as a bracket so that dew condensation does not occur. It is necessary to interpose a heat insulating material. For example, a donut-shaped heat insulating material made of hard urethane foam is surrounded by a U band, and the U band is fixed to a mounting side member such as a bracket, a portal mount, or a steady rest. Piping supports are known (Non-Patent Document 1).

However, since the heat insulating material is required to have a function of transmitting a load for supporting the pipe, the heat insulating performance is limited.

That is, as a heat insulating material made of hard urethane foam suitable for pipe support, a thermal conductivity of 0.057 and a compression strength of 50 kgf / cm ² (extracted from "Insulation pipe support" of Niei Intec Co., Ltd. HP). ), Or the one with a thermal conductivity of 0.053 and a compression strength of 46 kgf / cm ² (450 N / cm ² ) (extracted from "Sleeper L" of Showa Corporation HP Co., Ltd.), but heat Since the conductivity is about 0.05 in each case, there is a limit to reducing the thickness of the heat insulating structure, which makes it difficult to install in narrow places, and the heat insulating material wrapped around the pipe is used for the pipe support. Since it is naturally difficult to stack from above, if a gap is formed between the heat insulating material around the pipe and the heat insulating material of the pipe support, there is a problem that dew condensation may occur in the gap.

By the way, a heat insulating material whose thermal conductivity is reduced to the same level as that of air is also known. For example, hard urethane foam heat insulating plate No. 2 type 1 has a thermal conductivity of 0.023 or less, but has a compressive strength. Is 10 N / cm ² or more (extracted from "Hard Urethane Foam Insulation Standard Construction Manual Material Edition" of Urethane Foam Industry Association HP). Since it is significantly smaller at / 50, it is difficult to use it as a heat insulating material that also serves as a pipe support.

Further, in the pipe support described in Non-Patent Document 1, in addition to the above-mentioned problem, since the heat insulating material and the U band are separate bodies, there is a problem that the pipe fixing work becomes complicated.

The present invention has been made in consideration of the above-mentioned circumstances, and provides a pipe support that can improve heat insulation performance while maintaining a load transmission function and can improve workability when fixing a pipe. The purpose is to do.

In order to achieve the above object, as described in claim 1, the pipe support according to the present invention has a pipe insertion portion formed in an out-of-plane direction and curved in an annular shape, and a radial direction from the opposite end portion of the pipe insertion portion. A metal body composed of a pair of connecting portions facing each other is provided, and the pair of connecting portions are connected to the ceiling surface or the lower surface of the upper floor slab or the wall surface via a predetermined connecting tool. In a pipe support that can support a pipe inserted in the space inside the pipe insertion part,
A load transmitting means made of a resin material is arranged between the pipe insertion portion and the pipe so that the load is transmitted in a cylindrical shape centered on the material shaft of the pipe. The load transmitting means is provided with two opposing end faces extending along the material axis in the vicinity of the pair of connecting portions so as to form a C shape in a cross section orthogonal to the material axis of the pipe, and the two opposing ends are extended. The end faces are configured to be separated from each other when the pipe insertion portion is open and to be in contact with each other when the pipe insertion portion is closed, and at least both ends of the load transmitting means are attached to the load transmitting means along the material axis direction of the pipe. The gaps extending to the vicinity are discretely arranged along the circumferential direction of the pipe.

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

Further, in the piping support 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, in the pipe support according to the present invention, the inner surfaces of the facing grooves are separated from each other on the inner peripheral side of the load transmitting means and on the opposite side of the pair of connecting portions when the pipe insertion portion is open. When the pipe insertion portion is closed and the pipe insertion portion is closed, a notch is provided so that the inner surfaces of the facing grooves are in contact with each other.

Further, the pipe support according to the present invention is configured by configuring the load transmitting means as a load transmitting unit so that the pipe insertion portion is embedded in the load transmitting means.

Further, the pipe support according to the present invention is configured by configuring the load transmitting means as a load transmitting unit so that the pipe insertion portion is embedded in the load transmitting means.

In the pipe support according to the present invention, from a pipe insertion portion formed so as to be curved in an out-of-plane direction and in an annular shape, and from a pair of connecting portions facing each other extending in the radial direction from the facing ends of the pipe insertion portion. In the present invention, a load transmitting means made of a resin material is arranged between the pipe insertion portion and the pipe so that the load can be transmitted, and the load transmitting means is provided. The gaps extending along the material axis direction of the pipe are discretely arranged along the circumferential direction of the pipe.

In this way, by appropriately selecting the resin material and appropriately setting the discrete arrangement form of the voids, it is possible to form a heat insulating space having a sufficient volume in the load transmitting means while ensuring the load transmitting function. This makes it 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.

Here, the load transmitting means has a cylindrical shape centered on the material axis of the pipe as a whole, but a pair of connecting portions so as to form a C shape in a cross section orthogonal to the material axis of the pipe. Two facing end faces are extended along the material axis in the vicinity of the pipe, and the two facing end faces are configured to be separated from each other when the pipe insertion portion is open and to be in contact with each other when the pipe insertion portion is closed. Therefore, there is no problem in inserting the pipe into the inner space of the pipe insertion part, and after the work of supporting the pipe is completed, the two opposing end faces of the load transmitting means also come into contact with each other, so that the pipe and the metal There is no risk that the heat insulating property will deteriorate with the main body.

Further, in the pipe support according to the present invention, since the load transmitting means is configured to have a cylindrical shape centered on the material axis of the pipe, the outer peripheral surface of the pipe is on the inner peripheral surface of the load transmitting means. In the abutted state, the load from the pipe is loaded on the load transmitting means in a dispersed state and transmitted to the pipe insertion part, while the load from the pipe insertion part is transmitted through the inner peripheral surface of the load transmitting means. The load is loaded on the outer peripheral surface of the pipe in a dispersed state, and thus it is possible to prevent stress concentration from occurring in the pipe and the load transmitting means.

A typical example is that the metal body is composed of a U-band, but as long as it can be hung from the ceiling surface or the lower surface of the upper floor slab via a connecting tool such as a hanging bolt, or through a similar connecting tool, the wall The configuration is arbitrary as long as it can be fixed to.

Further, the metal body is provided with a cross-sectional defect such as an opening or a notch in a portion of the metal body opposite to the pair of connecting portions in order to facilitate the opening / closing operation of the pipe insertion portion, or a hinge. A typical example is a configuration in which the bending rigidity at the portion is reduced by providing the portion.

The load that will be generated in the load transmitting means includes the tightening load by the metal body, the seismic load generated in the pipe, the vibration load of the fluid flowing in the pipe, the temperature load, and the like.

The load transmitting means shall be formed of a resin material having rigidity and strength capable of transmitting a load between the pipe insertion portion and the pipe, and is preferably formed by injection molding using, for example, a thermoplastic elastomer as the resin material. ..

In order to more reliably exert the load distribution function of the load transmission means described above, it is desirable to configure the inner peripheral surface so as to be smooth on the entire surface.

Here, to make the inner peripheral surface smooth over the entire surface means that the apparent area of the inner peripheral surface (the area of the area surrounded by the peripheral edge) may be an area that can contribute to load transmission in terms of design. It shall mean a state.

When the load transmitting means is configured so that both ends of the voids formed in the load transmitting means are open, it becomes easy to manufacture the voids using a mold during injection molding. If the load transmitting means is configured so that both ends of each gap are closed, the movement of air in and out of the gap 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 means so that the heat insulating performance of the load transmitting means is substantially ensured.

The specific configuration for closing both ends of each gap is arbitrary, but for example, a planar shape similar to the end face of the load transmitting means, for example, an annular closing plate is attached to each end face of the load transmitting means. It is possible to configure.

The voids formed in the load transmitting means can be formed of holes (circular holes) having a circular cross section, such as those formed in a lotus root, and cross the voids as long as the required heat insulating performance can be obtained. The surface shape is arbitrary, but if each void is formed so that their cross-sectional shape is hexagonal and they are arranged close to each other via a hexagonal partition wall, the load transmitting means is configured with a honeycomb structure. Therefore, 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 fixture, so that the circumference of the pipe can be overlapped. Even if there is a gap along the axial direction of the piping material between the heat insulating material and the load transmitting means of the piping support, there is no possibility that dew condensation will occur in the gap.

As long as the load transmitting means can be elastically deformed so that the two opposing end faces are separated from each other or abutted against each other according to the opening / closing operation of the pipe insertion portion, the specific configuration is arbitrary, and the load transmitting means has a gap. Coupled with the fact that the whole is more easily deformed due to the discrete arrangement, it is possible to follow the opening and closing operation of the pipe insertion part only by the elastic deformability of the resin material that constitutes the load transmission means. However, when the metal body is configured to have a reduced bending rigidity at a portion opposite to the pair of connecting portions, the bending deformation amount of the pipe insertion portion is maximized at the above-mentioned portion.

In such a case, the inner surfaces of the facing grooves are separated from each other and open in a V shape on the inner peripheral side of the load transmitting means and on the opposite side of the pair of connecting portions when the pipe insertion portion is open. When the pipe insertion portion is closed, it is possible to adopt a configuration in which the inner surfaces of the facing grooves are provided with notches that come into contact with each other.

According to such a configuration, it is possible to alleviate the bending stress generated in the load transmitting means during the pipe supporting work without deteriorating the heat insulating performance, and it is possible to prevent unexpected cracks in the load transmitting means. It becomes possible to do.

The load transmitting means may be arranged so that the load is transmitted to and from the pipe, and it is sufficient if the load transmitting means is arranged at least on the inner peripheral side, but the pipe insertion portion is embedded. If it is configured as a load transmission part in this way, the adhesive strength between the metal body and the pipe insertion part will be higher, the load transmission between the two will be more reliable, and the heat insulating material will be separate than before. The workability for mounting on piping is significantly improved.

The configuration in which the pipe insertion portion is embedded can be realized by injection molding in which the pipe insertion portion is a buried object and a thermoplastic elastomer is used as a resin material.

On the other hand, it is also possible to configure the load transmitting means as a detachable load transmitting member in the pipe insertion portion, and according to such a configuration, the load transmitting member can be easily manufactured.

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

FIG. 1 is an overall perspective view showing a pipe support according to the present embodiment, and FIGS. 2 (a) to 2 (c) are a side view of the pipe support according to the present embodiment and a view taken along the line AA. (Front view) and BB line cross-sectional view, FIGS. 3 (a) and 3 (b) are a CC line cross-sectional view and a DD line cross-sectional view of the pipe support according to the present embodiment, respectively.

As can be seen from these figures, the pipe support 1 according to the present embodiment is a so-called suspension band, and the pipe 6 to be arranged as a horizontal pipe below the ceiling or the upper floor slab. The metal main body 2 and the load transmitting unit 3 as a load transmitting means made of a resin material are provided.

The pipe 6 is intended for cold / hot water that requires heat insulation, particularly for cooling water flowing inside the pipe 6.

The metal body 2 is made of a strip-shaped steel material, and is formed in an out-of-plane direction and is curved in an annular shape. It is composed of a pair of connecting portions 5 and 5 facing each other that are extended, and the pair of connecting portions are connected to a connecting tool such as a hanging bolt while utilizing the bolt insertion holes 7 and 7 formed in the connecting portion (FIG. By connecting to the ceiling surface or the lower surface of the upper floor slab via (not shown), the pipe 6 inserted in the inner space of the pipe insertion portion 4 can be suspended.

A stiffening rib 8 for preventing so-called springback is provided in the pipe insertion portion 4 of the metal body 2 in the circumferential direction, and the unevenness thereof is a ridge 9 on the outer peripheral side and a groove 10 on the inner peripheral side. Appears as.

Further, in the pipe insertion portion 4, a portion located on the opposite side of the pair of connecting portions 5 and 5, that is, the lowermost end portion of the pipe insertion portion 4, is provided with a cross-section defect portion 14 formed of an opening, and FIG. The opening / closing operation of the pipe insertion portion 4 along the direction of the arrow shown in (b) can be easily performed.

The load transmission unit 3 is arranged between the pipe insertion portion 4 and the pipe 6 in a cylindrical shape centered on the material shaft of the pipe 6 so that the load is transmitted between the pipe insertion portions 4 and the pipe 6. In the cross section orthogonal to the material axis of the pipe 6, two facing end faces 15 and 15 are extended along the material axis in the vicinity of the pair of connecting portions 5 and 5 so as to form a C shape, and the two facing each other. The end faces are configured to be separated from each other when the pipe insertion portion 4 is open and to be in contact with each other when the pipe insertion portion 4 is closed.

As can be clearly seen in FIG. 3, the load transmitting portion 3 is provided so as to surround the pipe insertion portion 4 in a form of being embedded by insert molding. In addition, on the outer peripheral side of the load transmitting portion 3, a convex portion 32 along the circumferential direction is provided so as to cover the ridge 9 of the stiffening rib 8 except for the portion corresponding to the position where the cross-sectional defect portion 14 is provided. There is.

It is desirable that the load transmitting portion 3 is formed by injection molding using, for example, a thermoplastic elastomer as an injection material so as to have rigidity and strength capable of transmitting a load between the pipe insertion portion 4 and the pipe 6. ..

As shown in FIGS. 1 (a), 2 (b), 2 (c), 3 (a), and 3 (b), the load transmitting portion 3 has an inner peripheral surface 11 that is smooth over the entire surface. In other words, the apparent area of the inner peripheral surface 11 (the area of the area surrounded by the peripheral edge) is formed so as to be in a state where there is no problem in design even if the area can contribute to the load transmission.

Here, the load transmission unit 3 functions as a portion for transmitting the load between the pipe insertion portion 4 and the pipe 6 as described above, but in addition to the load transmission function, it functions as a portion for insulating heat insulation function. As described above, the gaps 12 extending to both ends along the material axis direction of the pipe 6 and opened at both ends are arranged so as to be discretely arranged along the circumferential direction and the radial direction of the pipe.

The voids 12 are formed so that their cross-sectional shapes are hexagonal, and are arranged close to each other via the hexagonal partition wall 13.

In the pipe support 1 according to the present embodiment, the load transmission portion 3 is arranged on the pipe arrangement side in such a form that the pipe insertion portion 4 is embedded, and the material shaft of the pipe 6 is arranged in the load transmission portion. The voids 12 extending to both ends along the direction and opening at both ends are discretely arranged.

In this way, the load transmitting function is ensured in the load transmitting portion 3, and a heat insulating space having a sufficient volume is formed in the load transmitting portion.

Further, the load transmitting portion 3 is configured so as to have a cylindrical shape centered on the material shaft of the pipe 6 and so that the inner peripheral surface 11 thereof is smooth over the entire surface.

In this way, when the outer peripheral surface of the pipe 6 is in contact with the inner peripheral surface 11 of the load transmitting portion 3, the load from the pipe 6 is loaded on the load transmitting portion 3 in a distributed state and is loaded on the pipe insertion portion 4. On the other hand, the load from the pipe insertion portion 4 is loaded on the outer peripheral surface of the pipe 6 in a distributed state via the inner peripheral surface 11 of the load transmission portion 3.

FIG. 4 is a diagram showing a state in which the pipe support 1 according to the present embodiment is attached to the pipe 6. As shown in the figure, in order to attach the pipe support 1 to the pipe 6, the pipe insertion portion 4 is opened along the direction of the arrow in the figure to separate the two opposing end faces 15 and 15 of the load transmitting portion 3 from each other. Then, the pipe support 1 is arranged so that the pipe 6 is inserted into the inner space of the load transmitting portion 3 by utilizing the space extending between the facing end faces, and then the pipe insertion portion 4 is closed. , The two opposing end faces 15 and 15 of the load transmitting portion 3 are brought into contact with each other.

When the attachment of the pipe support 1 to the pipe 6 is completed, the bolt insertion holes 7 and 7 formed in the connecting portions 5 and 5 are used, and the connecting tool (not shown) such as a hanging bolt is used. By connecting to the ceiling surface or the lower surface of the upper floor slab, the pipe 6 inserted in the inner space of the pipe insertion portion 4 may be suspended.

As described above, according to the pipe support 1 according to the present embodiment, the load transmitting portion 3 is arranged on the pipe arranging side in a form in which the pipe insertion portion 4 is embedded, and the load transmitting portion is connected to the pipe. Since the voids 12 extending to both ends along the material axis direction of No. 6 and opened at both ends are discretely arranged, a load transmitting function is ensured in the load transmitting portion 3 and a heat insulating space having a sufficient volume is formed in the load transmitting portion. can do.

Therefore, it is possible to have a heat insulating performance equal to or higher than that of the heat insulating material using the conventional rigid urethane foam in a more economical form.

Further, according to the pipe support 1 according to the present embodiment, the load transmitting portion 3 is provided so that the pipe insertion portion 4 is embedded in the load transmitting portion by insert molding. Therefore, the load transmitting portion 3 The adhesive strength between the pipe and the pipe insertion part 4 is increased, the unity of the two is enhanced, the load transmission between the two is more reliable, and the work when mounting the heat insulating material on the pipe is more reliable than before. The sex is greatly improved.

Further, according to the piping support 1 according to the present embodiment, the voids 12 are formed so that their cross-sectional shapes are hexagonal, and they are arranged close to each other via the hexagonal partition wall 13. The load transmitting portion 3 is formed of a honeycomb structure, and thus it is possible to form a gap with a cross-sectional area close to the maximum while ensuring a sufficient load transmitting function, and the heat insulating performance is remarkably improved. Can be done.

Therefore, the thickness of the heat insulating structure can be suppressed as compared with the conventional one, the workability in a narrow place is improved, and the heat insulating material wrapped around the pipe can be overlapped on the pipe support 1, so that the pipe can be piped. Even if a gap is formed along the axial direction of the piping material between the surrounding heat insulating material (not shown) and the load transmitting portion 3 of the piping support 1, there is no possibility that dew condensation will occur in the gap.

Further, according to the pipe support 1 according to the present embodiment, the load transmitting portion 3 is configured so as to have a cylindrical shape centered on the material shaft of the pipe 6, and the inner peripheral surface 11 of the load transmitting portion is entirely covered. In the state where the outer peripheral surface of the pipe 6 is in contact with the inner peripheral surface 11 of the load transmission unit 3, the load from the pipe 6 is loaded on the load transmission unit 3 in a distributed state. While being transmitted to the pipe insertion portion 4, the load from the pipe insertion portion 4 is loaded on the outer peripheral surface of the pipe 6 in a distributed state via the inner peripheral surface 11 of the load transmission portion 3, and thus the pipe 6 It is possible to prevent stress concentration from occurring in the load transmitting portion 3 and the load transmitting portion 3.

Here, the load transmitting unit 3 has a cylindrical shape centered on the material axis of the pipe 6 as a whole, but has a pair of C-shaped cross sections perpendicular to the material axis of the pipe 6. Two facing end faces 15 and 15 are extended along the material axis in the vicinity of the connecting portions 5 and 5, and the two facing end faces are separated from each other and closed when the pipe insertion portion 4 is open. Since it is configured to be in contact with each other in the state of being in contact with each other, there is no problem in the work of inserting the pipe 6 into the inner space of the pipe insertion part 4, and after the work of supporting the pipe is completed, the load transmission part 4 Since the two facing end faces 15 and 15 also come into contact with each other, there is no possibility that the heat insulating property is deteriorated between the pipe 6 and the metal body 2.

In the present embodiment, the load transmitting unit 3 is used as the load transmitting means, but the load transmitting means of the present invention may be arranged so as to transmit the load to and from the piping, and at least the inner circumference thereof may be used. It suffices if it is arranged on the side, and the pipe insertion portion 4 may be exposed on the outer peripheral side.

Further, in the present embodiment, as the metal main body, the metal main body 2 is formed by providing the cross-sectional defect portion 14 at the portion opposite to the pair of connecting portions 5 and 5 (the lowermost portion of the pipe insertion portion 4). Instead of this, a metal body having a hinge portion provided at the same portion may be used.

Further, in the present embodiment, the pipe insertion portion 4 of the present invention is formed by the pipe insertion portion 4 provided with the stiffening rib 8, but the springback of the metal body can be prevented by, for example, the rigidity of the load transmitting means. If this is the case, instead of this, the pipe insertion portion of the present invention may be configured by a flat pipe insertion portion without stiffening ribs.

Further, in the present embodiment, the gap provided in the load transmitting portion is a gap 12 formed so that the cross-sectional shape is hexagonal, but the gap of the present invention is not limited to such a shape, for example. As shown in FIG. 5, the circular void 51 may be formed.

Further, in the present embodiment, the gap provided in the load transmission portion is a gap 12 extending to both ends along the material axis direction of the pipe 2 and opening at both ends. As shown in FIG. 6, the load transmission of the present invention is performed. By attaching ring-shaped closing plates 61 and 61 to both ends of the load transmission main body 3'which is configured in the same manner as the load transmission portion 3, a gap formed in the load transmission portion can be formed. The gap 62 may be formed so as to extend to the vicinity of both ends along the material axis direction of the pipe 6 and be closed at both ends.

According to such a modification, the movement of air entering and exiting the void 62 is prevented, so that the heat insulating performance can be further improved.

Further, in the present embodiment, since the metal main body is a metal main body 2 in which the bending rigidity at the lowermost end portion is reduced by providing the cross-sectional defect portion 14 at the lowermost end portion of the pipe insertion portion 4, the pipe insertion portion is formed. With the opening operation of the portion 4, the bending stress of the load transmitting portion 3 increases at the lowermost end, and the load transmitting portion may be cracked.

In such a case, as shown in FIG. 7, the pipe is inserted at the inner peripheral side of the load transmitting portion 3 and on the opposite side of the pair of connecting portions 5 and 5, that is, at a position corresponding to the lowermost end portion of the pipe insertion portion 4. When the portion 4 is open, the facing groove inner surfaces 71 and 71 are separated from each other and open in a V shape, and when the pipe insertion portion is closed, the facing groove inner surfaces 71 and 71 are provided with a notch 72 in contact with each other. You can use it.

According to such a configuration, it is possible to relax the bending stress generated in the load transmitting portion 3 during the pipe support work, unexpected cracks occur in the load transmitting portion 3, and further, the heat insulating performance is deteriorated due to the cracks. Can be prevented.

When the pipe insertion portion 4 is to be opened, the hexagonal void 12 is shear-deformed in response to the opening operation, and the resin material constituting the load transmission portion 3 is formed. If the bending deformation of the load transmitting portion 3 is absorbed and the cracking of the load transmitting portion 3 is prevented in combination with the elastic deformability, it is not necessary to provide the notch 72.

Further, in the present embodiment, the load transmission means of the present invention is configured by the load transmission unit 3 in which the pipe insertion portion 4 is embedded, but instead, as shown in FIG. 8, the pipe insertion portion 4 is used. The load transmitting means of the present invention can be configured by the detachable load transmitting member 91, and in such a configuration, the claws 92 and 92 provided at each edge of the load transmitting member 91 in the width direction are used as a pipe insertion portion. The load transmitting member may be attached to the pipe insertion portion 4 so as to be locked to each edge portion in the width direction of 4.

It is desirable that the load transmitting member 91 is provided with a convex portion 102 that fits into the groove 10 of the stiffening rib 8 so that the load is reliably transmitted to and from the pipe insertion portion 4.

In the load transmitting member 91, similarly to the load transmitting portion 3, voids 12 extending to both ends along the material axis direction of the pipe 6 and opening at both ends are discretely arranged along the circumferential direction and the radial direction of the pipe. In addition, the cross-sectional shape of the gap 12 is formed to be hexagonal, and the gaps 12 are arranged close to each other via the hexagonal partition wall 13, but the description thereof will be omitted here.

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