Description

Technical Field

[0001] The present invention relates to a pipe support used when supporting various pipes in the form of a suspension band or a vertical band.

Background Art

[0002] In air conditioning facility construction and sanitary facility construction, various pipes are used according to the application and purpose, and are generally classified into metal pipes and resin pipes when classified by material.

[0003] For example, for water supply pipes, lined steel pipes with an inner surface coated with polyethylene or rigid polyvinyl chloride, resin pipes such as rigid polyvinyl chloride pipes and polyethylene pipes are used, and for hot water supply pipes, stainless steel pipes and heat-resistant rigid polyvinyl chloride-lined steel pipes are used.

[0004] These pipes, if they are horizontal pipes, are suspended from the ceiling or the upper floor slab by a suspension band, and if they are rising pipes, they are installed in the building by being fixed to the wall with a vertical band. These pipe supports such as suspension bands or vertical bands are configured such that a pipe insertion portion is formed by bending a strip-shaped steel material into an annular shape in the out-of-plane direction so that a pipe can be inserted inside, and a pair of connecting portions are respectively extended in the radial direction so as to face each other from each end of the pipe insertion portion. Between the pair of connecting portions, the lower end of a connector called a tumble, which is connected to the ceiling surface or the lower surface of the upper floor slab via a connecting bolt, is sandwiched, or the tip of a tumble connected to the wall surface via a connecting bolt is sandwiched, and after inserting the above-mentioned pipe into the pipe insertion portion, bolts are inserted through the pair of connecting portions and the tumble and tightened, so that the pipe can be suspended from the ceiling or the upper floor slab or fixed to the wall.

[0005] Here, the pipe insertion section, which is made of a strip of steel, is constantly subjected to the weight of the pipe as a vertical load, and the inertial force during an earthquake acts as a horizontal load, while the reaction forces of these forces act on the circumferential surface of the pipe. In order to reduce the manufacturing cost of the pipe support, the width of the steel material must be limited to about 25 mm, so the surface on which the reaction force from the pipe insertion section acts is concentrated in a narrow area of ​​the pipe, and as a result, if the strength of the pipe has decreased due to corrosion or the like, there is a risk that the pipe will rupture. However, the applicant has developed a pipe support in which a load transmission means made of elastomer is covered over the pipe insertion section so that load transmission occurs between the pipe insertion section and the pipe (Patent Document 1).

[0006] With such a pipe support, the self-weight of the pipe and the reaction force to the inertial force of the pipe during an earthquake act on the pipe in a distributed manner. Thus, the shear stress generated in the pipe is reduced, preventing stress concentration in the pipe and, consequently, preventing rupture.

[0007] Furthermore, when cooling water flows through piping, condensation can corrode metal products or drip downwards, causing various problems. Therefore, it is necessary to wrap the piping with insulation material to prevent heat loss, and the pipe supports must also have thermal insulation properties where the piping is supported. With the aforementioned pipe supports, the metal pipe insertion part is covered with elastomer, so the elastomer provides thermal insulation, preventing problems caused by condensation. [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] Patent No. 7499314 [Overview of the project] [Problems that the invention aims to solve]

[0009] However, in the pipe support described above, because the lower end or tip of the turnbuckle is sandwiched between a pair of connecting parts extending from the pipe insertion part, a gap is created between the pair of connecting parts equal to the thickness of the plate material forming the turnbuckle.

[0010] As a result, condensation water formed on the connecting bolts and turnbuckles could seep into the piping through the gap between the pair of connecting parts, eventually reaching the outer surface of the piping and potentially corroding it. Alternatively, air could flow into the outer surface of the piping through the aforementioned gap, causing water vapor in the air to condense and similarly corrode the piping. [Means for solving the problem]

[0011] This invention has been made in consideration of the circumstances described above, and aims to provide a pipe support that can prevent gaps from forming between a pair of connecting parts.

[0012] To achieve the above objective, the pipe support according to the present invention comprises a metal body consisting of a pipe insertion portion formed to be curved out of plane and annularly and and a pair of opposing connecting portions extending radially from the opposing ends of the pipe insertion portion, and a load transmission portion made of a resin material provided to cover the pipe insertion portion so as to transmit load between the pipe insertion portion and the pipe inserted in the inner space of the pipe insertion portion, and the pipe support body is configured to support the pipe by connecting the pair of connecting portions to the ceiling surface, the underside of the upper floor slab, or the wall surface, as described in claim 1, The device is provided with a pair of sealing portions that cover at least the base ends of each of the pair of connecting portions, and a fastening member through which the pair of connecting portions are inserted surrounds the pair of sealing portions, the fastening member fastening the pair of connecting portions together so that the pair of sealing portions abut each other on their opposing surfaces.

[0013] Furthermore, the pipe support according to the present invention has the pair of sealing portions formed in a continuous and integral manner with the load transmission portion.

[0014] Furthermore, the pipe support according to the present invention extends the pair of sealing portions to or beyond the vicinity of the center of the pair of connecting portions.

[0015] Furthermore, the pipe support according to the present invention is provided with a locking projection on the base end side of at least one of the pair of sealing portions, which engages with the edge of the binding member.

[0016] Furthermore, the pipe support according to the present invention includes a seal pad having an opening through which the pair of connecting parts are inserted, surrounding the pair of sealing parts, and having an insertion slit that communicates with the opening, and the seal pad is curved so that its back surface abuts against the circumferential surface of the heat-insulating material wrapped around the pipe.

[0017] In the pipe support according to the present invention, a sealing portion is provided on the base end side of each connecting portion extending from the opposing ends of the pipe insertion portion to form a pair of sealing portions, and a fastening member is provided that surrounds the pair of sealing portions through which the pair of connecting portions are inserted, and the fastening member fastens the pair of connecting portions together so that the pair of sealing portions abut each other on their opposing surfaces.

[0018] This design eliminates gaps between the pair of connecting parts. As a result, even if condensation forms on the connecting bolts or turnbuckles, there is no risk of the condensation seeping into the piping through the aforementioned gaps and corroding the pipes. Similarly, air cannot flow into the outer surface of the pipes through the aforementioned gaps, and the water vapor in the air cannot condense on the outer surface of the pipes and corrode them.

[0019] The metal body consists of a pipe insertion portion that is curved in an annular shape out of the plane and a pair of opposing connecting portions that extend radially from the opposite ends of the pipe insertion portion, and the specific configuration is arbitrary as long as a pair of sealing portions can be provided that cover at least the base ends of each of the pair of connecting portions.

[0020] It is sufficient that the pair of seal portions are provided in such a manner as to cover at least the base end sides of the pair of connecting portions respectively. Even if they are discontinuous with the load transmission portion covering the pipe insertion portion, if they are formed integrally and continuously with the load transmission portion, it is possible to suppress the manufacturing cost of the entire pipe support.

[0021] Also, the pair of seal portions may not be provided other than the base end sides of the pair of connecting portions. However, if they extend to or beyond the vicinity of the center of the pair of connecting portions, by forming them with a resin material having excellent heat insulation properties, particularly an elastomer, in addition to the sealing action of blocking the flow of water and air, it is also possible to enhance the heat insulation properties of the pair of connecting portions and thus the entire pipe support.

[0022] The binding member appropriately determines the inner dimension, particularly the inner dimension in the thickness direction, while appropriately considering the presence or degree of elastic deformation in the expansion and contraction direction so that the pair of seal portions fit snugly against their opposing surfaces when the pair of connecting portions are inserted.

[0023] In addition, when there is a possibility that the binding member is displaced from the binding position for some reason and the opposing surfaces of the pair of seal portions may be separated, a configuration may be adopted in which locking protrusions locked to the edge portion of the binding member are provided on at least one of the base end sides of the pair of seal portions.

[0024] Here, when a seal pad is provided with an opening through which the pair of connecting portions are inserted in a form surrounding the pair of seal portions and an insertion slit communicating with the opening is formed, and the seal pad is curved so that the back surface abuts against the peripheral surface of the heat insulating material wound around the pipe, the flow of water and air in the pair of connecting portions is not only blocked at the base end side by the cooperative action of the pair of seal portions and the binding member, but also blocked at the tip side by the pair of seal portions and the seal pad. Thus, it is possible to more reliably prevent pipe corrosion caused by condensed water and also prevent the situation where water and air penetrate from the gap between the pair of seal portions and the heat insulating material.

[0025] It is desirable that the seal pad prevent the intrusion of water and air from the peripheral edge more reliably by sticking a tape between the peripheral surface of the heat insulating material so as to straddle the peripheral edge thereof.

Modes for Carrying Out the Invention

[0027] Hereinafter, embodiments of the pipe support according to the present invention will be described with reference to the accompanying drawings.

[0028] Figure 1 is an overall perspective view showing a pipe support 1 according to this embodiment. As shown in the figure, the pipe support 1 includes a pipe support body 9 called a suspension band, which is configured to suspend a pipe 6 that is to be arranged as a horizontal pipe below the ceiling or upper floor slab, and is composed of a metal body 2 and a load transmission part 3 made of resin material into which the metal body is embedded.

[0029] As shown in Figure (b), the metal body 2 is constructed from a strip-shaped steel material and consists of a pipe insertion section 4 that is curved in an annular shape out of the plane and a pair of connecting sections 5, 5 that are opposite to each other and extend radially from the opposing ends of the pipe insertion section. By utilizing the bolt insertion holes 7, 7 formed in the connecting sections and connecting them to the ceiling surface or the underside of the upper floor slab via connecting bolts such as suspension bolts or turnbuckles (not shown), the pipe 6 inserted into the inner space of the pipe insertion section 4 can be suspended.

[0030] The pipe insertion portion 4 of the metal body 2 is provided with stiffening ribs 8 in the circumferential direction to prevent so-called springback, and the irregularities of these appear as protrusions on the outer circumference and grooves on the inner circumference.

[0031] Furthermore, a cross-sectional defect 11 consisting of an opening is provided in the pipe insertion section 4 at the location opposite to the connecting sections 5, 5, i.e., near the lowest end, allowing for easy opening and closing of the pipe insertion section 4.

[0032] The load transmission section 3 is provided so as to surround the pipe insertion section 4, which is embedded within it, and load transmission occurs between the pipe insertion section 4 and the pipe 6 in the area extending between them (inner circumference). On the outer circumference of the load transmission section 3, except for the area corresponding to the location of the cross-sectional defect 11, a convex portion 12 is provided along the circumferential direction to cover the protrusions of the stiffening rib 8.

[0033] The load transmission section 3 is configured so that the inner circumference is flat, preventing the reinforcing rib 8 from appearing as a groove.

[0034] The pipe support body 9 can be manufactured by insert molding, using resin materials such as synthetic resin or elastomer as the injection molding material, with the pipe insertion portion 4 serving as an embedded object (insert). The type of synthetic resin or elastomer should be appropriately selected according to the temperature of the fluid flowing through the pipe 6 and the support load.

[0035] The pipe support 1 according to this embodiment is provided with a pair of sealing portions 13, 13 that cover the connecting portions 5, 5 from their base ends to beyond the vicinity of the center, and also includes a fastening member 10 through which the connecting portions 5, 5 are inserted, surrounding the sealing portions.

[0036] The sealing portions 13, 13 are preferably made of the same material as the load transmission portion 3, for example, an elastomer, and are formed continuously and integrally with the load transmission portion 3 as shown in Figure 1.

[0037] The fastening member 10 is rectangular in shape, and as can be clearly seen in Figure 2, the connecting parts 5, 5 are fastened together so that the sealing parts 13, 13 come into contact with each other on their opposing surfaces, and it can be made of a synthetic resin such as polypropylene.

[0038] To suspend the pipe 6 using the pipe support 1, first open the pipe insertion section 4, which is covered with the load transmission section 3, and pass the pipe 6 through the inner space therein. Then, return the pipe insertion section 4 to its original position and close the connecting sections 5, 5, and then insert the connecting sections 5, 5 into the binding member 10 as shown in Figure 3(a).

[0039] Next, as shown in Figure (b), the tip of a turnbuckle 31, which is one of the connectors, is inserted between the connecting parts 5, 5. Then, as shown in Figure (c), a bolt 33 is passed through the bolt insertion hole (not shown) of the turnbuckle 31 and the bolt insertion holes 7, 7 of the connecting parts 5, 5, and a nut 34 is screwed onto the tip of the bolt to fasten it, thereby suspending the piping 6 from the ceiling or upper floor via the turnbuckle 31 and the suspension bolt 32 connected to it.

[0040] Simultaneously with or in parallel with this operation, the fastening member 10 is lowered and the connecting parts 5, 5 are fastened together so that the sealing parts 13, 13 come into contact with each other at their opposing surfaces 33, 33, as shown in Figure (c).

[0041] Next, as shown in Figure 4, the insulation material 41 is wrapped around the pipe 6.

[0042] As described above, according to the pipe support 1 of this embodiment, a sealing portion 13 is provided on the base end side of each connecting portion 5, 5 extending from the opposing ends of the pipe insertion portion 4 to form a pair of sealing portions, and a binding member 10 is provided that surrounds the pair of sealing portions through which the connecting portions 5, 5 are inserted, and the binding member is used to bind the connecting portions 5, 5 together so that the sealing portions 13, 13 come into contact with each other at their opposing surfaces 33, 33, so that no gap is created between the connecting portions 5, 5.

[0043] Therefore, even if condensation forms on the suspension bolts 32 or turnbuckles 31, there is no risk of the condensation seeping into the pipe 6 through the aforementioned gap and corroding the pipe. Similarly, there is no risk of air flowing into the outer surface of the pipe 6 through the aforementioned gap and water vapor in the air condensing on the outer surface of the pipe 6 and corroding the pipe.

[0044] Furthermore, according to the pipe support 1 of this embodiment, since the sealing portions 13, 13 are extended beyond the vicinity of the center of the connecting portions 5, 5, it is possible to further enhance the sealing effect that blocks the intrusion of water and air.

[0045] Furthermore, according to the pipe support 1 of this embodiment, since the sealing portions 13, 13 extend beyond the vicinity of the center of the connecting portions 5, 5, by forming the sealing portions with a resin material with excellent heat insulation properties, particularly an elastomer, it is possible to improve the overall heat insulation performance not only through sealing but also through the heat insulation effect of the heat insulating material 41.

[0046] Furthermore, according to the pipe support 1 of this embodiment, the sealing portions 13, 13 are formed in a continuous and integral manner with the load transmission portion 3, which simplifies the manufacturing process and results in a more economical design.

[0047] In this embodiment, synthetic resins and elastomers can be arbitrarily selected as the resin material. If an elastomer is selected, its elasticity will provide vibration damping in the load transmission section 3, suppressing vibrations caused by the medium flowing through the pipe 6. In addition, the load transmission section 3 and the seal sections 13, 13 will provide thermal insulation, which, combined with the thermal insulation effect of the thermal insulation material 41, will suppress the generation of condensation on the circumferential surface of the pipe 6 and the metal body 2, even when cooling water flows through the pipe 6.

[0048] Furthermore, in this embodiment, the pipe support body is a suspension band, assuming that the pipes are suspended from the ceiling or upper floor slab. However, it is also possible to apply this to a vertical band for fixing the pipes to a wall instead.

[0049] Furthermore, in this embodiment, the load transmission section 3, which is configured so that its inner circumferential surface is flat, is used as the load transmission section of the present invention. However, instead, as shown in Figure 5, the load transmission section 53 may be provided with a projection 51 on its inner circumferential surface to enhance the vibration damping and heat insulation effects described above.

[0050] Furthermore, although not specifically mentioned in this embodiment or the above-described modifications, the sealing portion of the present invention does not necessarily need to extend beyond the vicinity of the center of the connecting portions 5, 5, as shown in sealing portions 13, 13. The sealing effect may be slightly reduced, but the sealing portion 61, 61 may cover only the base end side of the connecting portions 5, 5, as shown in Figure 6(a).

[0051] Furthermore, although not specifically mentioned in this embodiment or the above-described modifications, the seal portion of the present invention does not necessarily have to be formed in a continuous and integral manner with the load transmission portion 3, as shown in seal portions 13, 13. The seal portion 62, 62 may be discontinuous from the load transmission portion 3, as shown in Figure 6(b), although this may make the manufacturing process slightly more complicated.

[0052] Furthermore, although not specifically mentioned in this embodiment or the above-described modifications, as shown in Figure 7(a), a configuration is also possible in which a locking projection 71 is provided on the base end side of at least one of the sealing portions 13, 13, to which the edge of the fastening member 10 is locked.

[0053] The locking projection 71 is triangular in shape when viewed from above, with two vertices at the base end of the connecting portion 5, 5 and one vertex at the tip end. The triangular plane connecting these vertices is approximately the same height (flush surface) as the sealing portion 13, 13 at the tip end vertex, and protrudes from the two base end vertices, creating a step between it and the sealing portion 13, 13.

[0054] In this configuration, the fastening member 10 initially moves smoothly over the locking projection 71 when lowering (Figure (a)), and as it is lowered further, its upper edge locks into the protruding portion of the locking projection 71 (Figure (b)).

[0055] Therefore, it is possible to prevent the binding member 10 from moving upward from its lowered position, which would cause the opposing surfaces 33, 33 of the sealing portions 13, 13 to separate from each other.

[0056] Furthermore, although not specifically mentioned in this embodiment or the above-described modifications, the pipe support according to the present invention can be a pipe support 1' comprising a pipe support body 9, a binding member 10, and a seal pad 81, as shown in Figure 8(a).

[0057] The seal pad 81 has a rectangular opening 82 near its center, through which an insertion slit 83 is formed. As shown in Figure (b), the opening 82 is designed so that the connecting parts 5, 5 are inserted through it, surrounding the seal parts 13, 13.

[0058] Furthermore, the seal pad 81 is curved overall so that its back surface abuts against the circumferential surface of the insulation material 41 wrapped around the pipe 6.

[0059] In this configuration, it becomes possible to prevent condensation and air from entering through the gap between the seal portions 13, 13 and the insulation material 41, thereby more reliably preventing the aforementioned pipe corrosion caused by condensation.

[0060] To install the seal pad 81, after wrapping the insulation material 41 around the pipe 6, as shown in Figure 8, the seal pad 81 is pushed in the direction of the material axis of the pipe 6 so that the connecting parts 5,5 are inserted into the insertion slits 83 of the seal pad 81 and the connecting parts 5,5 pass through the opening 82.

[0061] In this way, the seal pad 81 can be attached without any interference with the suspension bolts 32 or turnbuckles 31 (not shown).

[0062] Next, the sealing pad 81 is pressed down, and its back surface is brought into contact with the peripheral surface of the heat-insulating material 41.

[0063] Here, if necessary, sealing tape (not shown) can be applied so as to straddle the periphery of the sealing pad 81 and the periphery of the insulation material 41, thereby more reliably preventing water and air from entering from the periphery of the sealing pad 81.

[0064] Furthermore, although not specifically mentioned in this embodiment or the above-described modifications, the metal body constituting the pipe support is composed of a pipe insertion portion that is curved in an annular shape out of plane and a pair of opposing connecting portions that extend radially from the opposing ends of the pipe insertion portion. The specific configuration is arbitrary as long as a pair of sealing portions can be provided that cover at least the base ends of each of these connecting portions, and the metal body 92 shown in Figures 9 and 10 can be used instead of the metal body 2 in this embodiment.

[0065] The metal body 92 shown in the figure, like the metal body 2, is constructed from a strip of steel and consists of a pipe insertion section 94 that is curved in an annular shape out of plane and a pair of connecting sections 95, 95 that extend radially from the opposite ends of the pipe insertion section and face each other. By using the bolt insertion holes 7, 7 formed in the connecting sections and connecting them to the ceiling surface or the underside of the upper floor slab via connecting bolts such as suspension bolts or turnbuckles (not shown), the pipe 6 inserted into the inner space of the pipe insertion section 94 can be suspended. Furthermore, a cross-sectional defect 101 consisting of an opening is provided in the part of the pipe insertion section 94 located on the opposite side of the connecting sections 95, 95, i.e., near the lowest end, so that the opening and closing operation of the pipe insertion section 94 can be easily performed.

[0066] The pipe support body 109, in which a load transmission part 93 made of resin material is covered over the pipe insertion part 94, and sealing parts 13, 13 are covered over the connecting parts 95, 95 so as to be continuous and integrated with the load transmission part, together with the binding member 10, or further equipped with a sealing pad 81, constitutes the pipe support device 1''.

[0067] In this modified example, in addition to the cross-sectional defect portion 101, cross-sectional defects 102, 102 are formed on both sides of the pipe insertion portion 94, and reinforcing ribs 108 are provided in two rows along the circumferential direction, sandwiching the cross-sectional defects, to prevent springback.

[0068] Furthermore, each connecting portion 95 is provided with cross-sectional defects 103, 103, each formed by creating two triangular openings with their hypotenuses adjacent to each other.

[0069] Furthermore, the connecting parts 95, 95 are provided with bent portions 109, 109 so that their tips are spaced apart from each other, making it easier to insert the lower end of the turnbuckle 31.

[0070] In this configuration, the reduced width of the metal body 92 results in lower heat conduction, and the resulting decrease in rigidity can be compensated for by the rigidity of, for example, the elastomer constituting the load transmission section 93 and the sealing sections 13, 13, thereby further enhancing thermal insulation without sacrificing suspension strength.

[0071] The procedure for suspending the pipe 6 using the pipe support 1″ is substantially the same as the embodiment described above, except that the tip of the turnbuckle 31 is inserted between the bent portions 109, 109 formed on the connecting portions 95, 95, as shown in Figure 11, so the explanation is omitted here.
