Description

[Technical field]

[0001] The present invention relates to a heat-insulating pipe support capable of supporting a pipe requiring insulation. [Background technology]

[0002] Insulated piping is particularly prone to condensation at pipe support parts, which are joints of the insulation material covering the pipe. Therefore, the pipe support parts where the insulation material joints occur are required to have the strength and insulation performance to withstand the weight of the pipe itself and the load applied to the pipe. In general, insulation support members made of rigid urethane foam or the like are used for the parts that contact the pipe. For example, as shown in Patent Document 1 and Patent Document 2, Fig. 2, etc., an insulation support member having a trapezoid shape with a through hole is supported and fixed by a support metal fitting.

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 55-119492 [Patent Document 2] Japanese Utility Model Application Publication No. 58-024581 Summary of the Invention [Problem to be solved by the invention]

[0004] However, as described above, the heat insulating support member that supports the pipes in the pipe support section has a trapezoidal shape, while the pipe insulation material connected to the heat insulating support member has a circular shape and covers the pipes. Therefore, since the trapezoidal heat insulating support member and the circular pipe insulation material have different cross-sectional shapes, it was not possible to wrap the finishing adhesive tape to seal the joints without any gaps after bonding them together with an adhesive. As a result, there was a problem that the heat insulating performance of the joints was reduced and condensation occurred at the joints where the sealing was insufficient.

[0005] Furthermore, Figures 1(a) and (b) show conventional insulated piping supports, but if a large load is applied to the insulated support members due to an earthquake or other factors, damage could occur at the parts that come into contact with the frame, as shown in Figures 2(a) and (b).

[0006] SUMMARY OF THE PRESENT EMBODIMENTS Accordingly, an object of the present invention is to provide a thermally insulated pipe support that can improve strength and thermal insulation performance. [Means for solving the problem]

[0007] (1) An insulated piping support device comprising at least an annular insulating support member that covers and supports a piping, a support base on which the insulating support member is placed and which is placed on a frame, and a U-shaped fixing member capable of fixing the insulating support member and the support base to the frame, wherein the support base is formed in an inverted triangle or an inverted trapezoid when viewed from the front, and supports the insulating support member on inclined support surfaces that face each other symmetrically on the left and right, and the lower bottom of the inverted triangle or the lower bottom of the inverted trapezoid is placed on the frame and is configured to be spaced apart from the bottom of the insulating support member by a predetermined distance, the U-shaped fixing member abuts at least the top of the outer periphery of the insulating support member, is inserted into insertion holes formed on both sides of the support base, and is fixed to the frame by a fastening member, and the rigidity of the inclined support surface of the support base is lower than the rigidity of the rigid insulation portion of the insulating support member.

[0008] (2) The insulated pipe support according to (1) above, wherein the width dimension of the insulating support member in the longitudinal cross-sectional direction of the pipe is larger than the width dimension of the support base in the longitudinal cross-sectional direction of the pipe.

[0009] (3) In the thermally insulated pipe support according to (1) or (2) above, the insertion holes formed on both sides of the support base are elongated holes extending in a transverse direction of the pipe of the thermally insulated support member.

[0010] (4) An insulated piping support device as described in any one of (1) to (3) above, in which leaf springs, each of which has a free end at the center of the support base, are provided on the inclined support surfaces of the support base, and the insulating support member is supported on the upper surface of the leaf springs. Effect of the Invention

[0011] According to the present invention, by making the heat insulating support member into a ring shape like the pipe insulation material connected before and after it, it is possible to wrap the finishing adhesive tape for sealing easily and without gaps, and it is possible to effectively suppress the occurrence of condensation. In addition, the rigidity of the inclined support surface of the support base is configured to be lower than the rigidity of the rigid insulation material, and a clearance is provided between the lower bottom of the inverted triangle or inverted trapezoid of the support base and the bottom of the heat insulating support member. Therefore, the load that was previously applied to the bottom of the heat insulating support member can be distributed to the left and right inclined support surfaces to reduce the load applied to the rigid insulation material, and further, the inclined support surface can be deformed to effectively prevent the heat insulating support member, which is important for maintaining the heat insulating performance, from being damaged. As a result, when performing repair work, it is possible to deal with the problem by only replacing the support base, without the trouble of replacing the heat insulating support member and the pipe insulation material connected before and after it, or reconnecting them.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the insulated pipe support of the present invention will be described with reference to the drawings.

[0014] Fig. 3 shows the thermally insulated pipe support 1 in this embodiment, and Fig. 3(a) shows an example in which a U-bolt is used as the U-shaped fixing member 3, and the support base 4 located at the bottom of the thermally insulated support member 2 is formed in an inverted trapezoid. Fig. 3(b) shows an example in which a U-band is used as the U-shaped fixing member 3, and the support base 4 located at the bottom of the thermally insulated support member 2 is formed in an inverted triangle.

[0015] More specifically, it has a ring-shaped heat-insulating support member 2 that covers piping (not shown) and supports the piping, and further, a through hole 22 on which the piping is placed is formed in the heat-insulating support member 2, and the heat-insulating support member 2 is placed on top of a support base 4 placed on a frame 5, as shown in the figure. Then, the heat-insulating support member 2 and the support base 4 are fixed to the frame 5 by tightening a fastening member 10 consisting of a nut with a U-shaped fixing member 3 such as a U-bolt or a U-band.

[0016] 4 shows a side view of the thermally insulated pipe support 1 in this embodiment, together with a side view of pipe insulation 8 covering a pipe 9, which is connected to the front and rear of the thermally insulated pipe support 1. As shown in the figure, the width dimension W1 in the longitudinal direction of the pipe of the thermally insulated support member 2 in this embodiment is formed to be larger than the width dimension W2 in the longitudinal direction of the pipe of the support base 4, and further, the cross-sectional shapes of the thermally insulated support member 2 and the pipe insulation 8 are substantially the same shape.

[0017] With this configuration, it is possible to adhere the pipe insulation material 8 to the front and rear of the heat insulation support member 2 at the joint 6, and then wrap the finishing adhesive tape 7 around the joint 6 without any gaps to seal it. This makes it possible to improve the heat insulation performance at the joint 6 compared to conventional methods, and effectively suppresses the occurrence of condensation at the joint 6, which has been a problem in the past. In addition, because the heat insulation support member 2 and the pipe insulation material 8 have the same cross-sectional shape, the adhesive tape 7 is easy to apply and the aesthetic appearance of the finished product can be improved.

[0018] Next, FIG. 5 shows the installation mode of the pipe 9 in the heat-insulating pipe support 1 of this embodiment. First, the rigid insulation material 21 made of rigid urethane foam or the like divided into two pieces of the heat-insulating support member 2 is removed in the manner shown in the figure, and the pipe 9 is placed in the through hole 22. In addition, as shown in the figure, the heat-insulating support member 2 of this embodiment has a rubber piece 23 wound around the outer periphery of the heat-insulating support member 2, which blocks the joints of the rigid insulation material 21 to improve the heat-insulating performance, and also serves as a buffer material between the support base 4 to obtain the effect of absorbing vibrations and shocks. In addition, the joints of the rigid insulation material 21 may be subjected to a joint processing to further improve the heat-insulating performance. In addition, if the level of the support base 4 needs to be adjusted, a spacer 51 having a predetermined thickness may be installed between the frame 5 and the support base 4 as shown in the figure.

[0019] Fig. 6(a) shows a front view of the support base 4 of the embodiment shown in Fig. 3(a), and Fig. 6(b) shows a top view of the support base 4. As shown in the figure, the support base 4 is formed in an inverted trapezoid shape in front view below the heat insulating support member 2, and has inclined support surfaces 42 that face each other symmetrically on the left and right. The inclined support surfaces 42 are configured to support the outer peripheral surface of the heat insulating support member 2 shown by the dashed line. Although the support base 4 of this embodiment is made of metal, it may be made of a material other than metal.

[0020] As shown in the figure, the lower bottom 43 of the inverted trapezoid is placed in contact with the base 5 (not shown) and is configured to be spaced apart from the bottom of the heat insulating support member 2 by a predetermined distance (h shown in the figure). In the embodiment shown in the figure, h is approximately 1 cm, and the support base 4 is formed with an angle and shape as shown in the figure. However, the dimensions, angles, and shapes are not necessarily limited to these, and any angle and dimensions can be used depending on the size of the heat insulating support member 2. The clearance (h shown in the figure) between the lower bottom 43 of the inverted trapezoid or inverted triangle and the bottom of the heat insulating support member 2 can be set in the range of 5 to 75 mm, preferably 5 to 35 mm, and more preferably 10 to 20 mm, to obtain the effects of the present invention.

[0021] Next, Fig. 7 shows the deformation state of the support base 4 when a large load is applied to the heat insulating support member 2 or the piping 9 due to an earthquake or other factors. Fig. 7(a) shows the deformation state when the support base 4 of Fig. 3(a) is used, and Fig. 7(b) shows the deformation state when the support base 4 of Fig. 3(b) is used. That is, the bending rigidity of the inclined support surface 42 of the support base 4 of this embodiment is configured to be lower than the bending rigidity of the rigid insulating material 21 of the heat insulating support member 2.

[0022] Therefore, when a large load is applied to the insulation support member 2 or the piping 9, the insulation support member 2 moves downward due to the presence of a clearance formed between the lower bottom 43 of the inverted trapezoid or inverted triangle and the bottom of the insulation support member 2, and at that time, the inclined support surface 42 is deformed as shown in the figure. With this configuration, it is possible to effectively prevent damage to the insulation support member 2, which is important for maintaining insulation performance, and when repair work is carried out, it is possible to deal with the problem by simply replacing the support base 4, eliminating the need to replace the insulation support member 2 and the piping insulation materials 8 connected before and after it, or the trouble of reconnecting them.

[0023] In this embodiment, as shown in Fig. 6(b), the insertion holes 41, through which the U-shaped fixing members 3 formed on both sides of the support base 4 are inserted, are formed as elongated holes in the piping transverse direction. Therefore, when a large load is applied to the heat-insulating support member 2 or the piping 9 and the support base 4 is deformed, both ends of the support base 4 can move laterally as shown in Fig. 7. With this configuration, the support base 4 becomes easier to deform, and the load applied to the heat-insulating support member 4 can be further suppressed.

[0024] 8(a) is a front view showing a load test on the thermal insulation pipe support 1 of this embodiment. Circular insertion holes 41 are formed on both sides of the support base 4 and the base is fixed to a testing machine with bolts, and a dummy steel pipe 9 is placed on the semicircular thermal insulation support member 2 to perform a load test.

[0025] FIG. 8(b) shows a graph of the relationship between the load and the amount of displacement as a result of the load test. The graph shows the results when the thickness of the support base 4 is 3.2 mm and the distance (h) between the bottom of the heat insulating support member 2 shown in FIG. 8(a) and the lower bottom 43 of the inverted triangle is about 16 mm. As shown in the graph, the support base 4 is deformed in the area surrounded by the dashed line, and it can be seen that the support base 4 absorbs a part of the large load applied to the heat insulating support member, which is applied suddenly from the beginning. A similar load test was also performed with the thickness of the support base 4 set to 4.5 mm, and the same results were obtained. From these results, the exceptional effect of the heat insulating pipe support of the present invention can be confirmed.

[0026] (Other embodiments) While one embodiment of the insulated pipe support of the present invention has been described above, the present invention is not necessarily limited to the above-mentioned configuration, and the following modifications are possible.

[0027] For example, FIG. 9 shows another embodiment of the heat-insulating pipe support 1. That is, FIG. 9(a) shows a front view of the support base 4 with a leaf spring 421 formed thereon, and FIG. 9(b) shows a top view of the support base 4. It is also possible to provide the leaf spring 421 with the central side of the support base 4 as the free end on the inclined support surface 42 of the support base 4. By configuring the heat-insulating support member 2 to be supported by the upper surface of the leaf spring 421, it becomes possible for the leaf spring 421 to further absorb the impact and load applied from the heat-insulating support member 2, reducing the load on the heat-insulating support member 2 and the pipe 9, and more effectively preventing damage to the heat-insulating support member 2 and the pipe 9. The leaf spring 421 may be welded to the support base 4, or may be formed by making a U-shaped cut in the inclined support surface 42 of the support base 4 and flipping the free end side upward. By forming it in this way, it is possible to save time and effort.

[0028] Although the embodiment and other embodiments of the present invention have been described above based on the drawings, the specific configuration is not limited to these embodiments. The scope of the present invention is indicated by the claims, not the description of the above embodiments, and further includes all modifications within the meaning and scope of the claims. In addition, the specific materials, dimensions, shapes, etc. described in the above embodiments can be modified within the scope of the present invention. [Explanation of symbols]
