Description

  The present invention is directed to air conditioning equipment such as cooling / heating, refrigeration / refrigeration equipment, water supply equipment, etc., pipes for circulating fluids such as refrigerant, hot water, cold water, and steam, etc. The present invention relates to a pipe support material used for a pipe support portion and a pipe support structure using the pipe support material when pipes are constructed on a wall (hereinafter referred to as a wall surface or the like).

  In the above facilities, piping for circulating the various fluids is piped on the wall surface of the building. These pipes are constructed in a state where they are covered with a heat insulating heat insulating material to prevent heat dissipation, heat absorption, condensation, and freezing. In recent years, resin-based foams and rubber-based foams are widely used as such heat insulation and heat insulating materials because they are excellent in heat insulation, easily available at low cost, and are lightweight. Patent Document 1 discloses a pipe cover using such a heat insulating and heat insulating material. Patent Document 2 discloses a pipe support structure for a wall surface of an air conditioner pipe covered with a heat insulating material.

  The pipe support structure disclosed in Patent Document 2 stores an air conditioner pipe covered with a heat insulating material in a cylindrical protective cover made of a molded body such as a synthetic resin, and the protective cover is attached to a wall surface of a building It is intended to support. Such a pipe support structure is used for an application in which appearance is emphasized as in a general house, etc., but an industrial facility, a commercial facility, a public facility, or the like provided with the above-described facilities. In the pipe construction, a heat insulating material (for example, foamed rubber or polystyrene) or a pipe covered with glass wool is wound with a tin plate, and pipe supports such as various angles or channel materials. Generally, it is directly supported by a bolt and fastened and fixed with a U-bolt or other fixing jig.

When the pipe covered with the heat insulating material is directly supported on the pipe support as described above, the load due to the weight of the pipe and the heat insulating material is applied to the portion supported by the pipe support after a long time has passed. Is applied, the heat insulating material in this portion is crushed, and the heat insulating effect is significantly reduced. From such a viewpoint, conventionally, a pipe support material molded into a bowl shape with a synthetic resin is interposed between the pipe support and the heat insulating material, and fixed with a binding material such as a wire, so that the heat insulating material is crushed and deformed. I tried to prevent it. In addition, in the patent document 3, the present applicant attaches the mat-like foam sheet around the heat insulating heat insulating material in a portion corresponding to the support portion by the pipe support, and between the pipe support and the heat insulating heat insulating material. A pipe support material and a pipe support structure were proposed.

  Therefore, in the case of the support material made of the above-mentioned cage-shaped synthetic resin molded body, it is necessary to prepare a support material having a size corresponding to various specification diameters of the piping structure, and inventory management is complicated. If a molded body of a slightly flexible synthetic resin is used, compatibility with various pipe diameters can be obtained due to its flexibility. However, although there are few types, it is necessary to prepare several types of sizes. In addition, because of the flexibility, there is a problem of crushing / deformation of the support material itself when used for a long period of time, which extends to the heat insulating material. The piping support material proposed in Patent Document 3 has a function to prevent the occurrence of condensation at the interface because of the compatibility with the heat insulating heat insulating material in addition to the crushing / deformation preventing effect of the heat insulating heat insulating material and the compatibility with the pipe diameter. However, since it is a mat-like foam sheet, it cannot be denied that there is still a problem of crushing / deformation of the support material itself when used for a long period of time.

  The present invention has been made in view of the above circumstances, and provides a pipe support material excellent in buckling resistance without causing crushing / deformation of a heat insulating heat insulating material and a pipe support structure using the pipe support material. The purpose is that.

  A pipe support material according to the first invention is a pipe support material used when a pipe covered with a heat insulating heat insulating material made of foam is supported on a building wall surface or the like by a pipe support, A pipe support comprising a synthetic resin sheet that is bent and shaped into a shape in which the recesses are alternately repeated, and the repetitive direction of the recesses and protrusions is directed to the periphery of the heat insulating heat insulating material along the circumferential direction of the heat insulating heat insulating material. The pipe and the heat insulating heat insulating material are supported in a state of being interposed between the heat insulating heat insulating material and the heat insulating heat insulating material.

  In the present invention, the synthetic resin sheet can have a thickness of 0.5 to 1.5 mm, preferably 1.0 to 1.5 mm. Moreover, it is good also considering the cross-sectional shape of the said protruding item | line and a concave item as a rectangular shape. In this case, it is desirable that the height of the ridge is 4 to 6 mm, and the width of the ridge and the groove is 5 to 7 mm.

  The pipe support structure according to the second invention is characterized in that a pipe covered with a heat insulating heat insulating material made of foam is supported on a building wall surface or the like by a pipe support through any of the pipe support materials. .

  According to the pipe support structure using the pipe support material according to the first invention or the pipe support material according to the second invention, between the heat insulating heat insulating material covering the pipe and the pipe support in the support portion by the pipe support. In addition, since the pipe support material is interposed, the load of the pipe and the heat insulating heat insulating material is dispersed by the buffer material action of the pipe support material, and the heat insulating heat insulating material is not easily crushed and deformed as described above. There is no concern about decline. Moreover, since the pipe support material is made of a synthetic resin sheet that is bent and shaped into a shape in which ridges and recesses are alternately repeated, the rib effect at the boundary between the ridges and recesses causes the piping and the heat insulating heat insulation material. The load resistance due to its own weight is strengthened, it is difficult to buckle even for long-term use, and the insulation and heat insulation material is effectively prevented from being crushed and deformed. And since crushing and a deformation | transformation of a heat insulation heat insulating material decrease, the attachment force (fastening force) by a piping support tool can be strengthened, and firm piping fixation is made. Furthermore, since the space by a recessed line is ensured between a heat insulation heat insulating material and a piping support material, generation | occurrence | production of the above dew condensation is also suppressed.

  In addition, since the pipe support material is made of a synthetic resin sheet, it is lightweight and easy to manufacture, and is bent and shaped into a shape in which the ridges and ridges are alternately repeated. It retains flexibility in the repeated direction of the strips and recesses. Therefore, if it is prepared as a long one extending in the repeating direction of the ridges (for example, a standard one having a width of 200 mm and a length of 1000 to 1200 mm), it is cut to a suitable length at the site construction, and a supporting portion of the pipe It can be used as if it is routed around the heat insulating and heat insulating material, and it is possible to respond appropriately to the various specification diameters of the piping structure without preparing various sizes, making inventory management complicated. There is nothing. Moreover, since it does not become bulky like what was shape | molded in the cage | basket shape, it is excellent also in the handling property in packing, transportation, and field construction.

  Moreover, if the thickness of the synthetic resin sheet is 0.5 to 1.5 mm, an appropriate buckling resistance can be obtained while being lightweight. Incidentally, when the thickness of the synthetic resin sheet is less than 0.5 mm, sufficient buckling resistance tends not to be obtained. When the thickness exceeds 1.5 mm, the flexibility decreases, and pipes of various sizes (insulation and heat insulation) are obtained. Material) tends to be poorly addressable.

When the cross-sectional shape of the ridges and ridges is rectangular, each side part (boundary part) forming the rectangular ridges and ridges is piped when wrapped around the heat insulating heat insulating material covering the pipes. It will be in the direction of centripetal. Therefore, in the support part by the pipe support, the side part is interposed so as to be substantially orthogonal to the surface of the heat insulating heat insulating material and the pipe support, the rib effect is remarkably exhibited, and the load resistance against the own weight of the pipe and the heat insulating heat insulating material Will be strengthened. In this case, if the height of the ridges is 4 to 6 mm and the widths of the ridges and recesses are 5 to 7 mm, this load resistance is more effectively expressed. Incidentally, when the height of the ridge (the depth of the concave shape) is less than 4 mm, the action as a buffer material tends to decrease, and when it exceeds 6 mm, the side surface tends to buckle with time. Further, when the width of the ridges and the ridges is less than 5 mm, the action as a cushioning material tends to decrease. When the width exceeds 7 mm, the spacing between the side surfaces increases, and thus the rib effect of the side surfaces tends to decrease. It becomes.
As a synthetic resin material which comprises a synthetic resin sheet, what is hard and has some softness | flexibility is desirable, and a polypropylene resin is specifically employ | adopted specifically ,.

  The best mode for carrying out the present invention will be described below with reference to the drawings. 1 is a partially broken perspective view showing an example of a pipe support material of the present invention, FIG. 2 is a longitudinal front view showing a pipe support structure using the pipe support material, and FIG. 3 is a cross-sectional view taken along line XX in FIG. 4 (a), 4 (b), and 4 (c) are cross-sectional views conceptually showing modifications of the piping support material.

  A pipe support material 10 shown in FIG. 1 includes a synthetic resin sheet 1 bent and shaped into a shape in which convex ridges 1a... And concave ridges 1b are alternately repeated, and in the illustrated example, the convex ridges 1a. It shows that the cross-sectional shape of is rectangular. Accordingly, these rectangular side surfaces constitute the boundary 1c of the ridges 1a and the recesses 1b. The thickness d of the synthetic resin sheet 1 is 0.5 to 1.5 mm (desirably 1.0 to 1.5 mm), the height of the ridge 1a (depth of the ridge 1b) h is 4 to 6 mm, and the ridge. The widths D1 and D2 of 1a and the groove 1b are 5 to 7 mm. Then, for example, it is manufactured in a mat shape having a total width D of 200 mm and a length L of 1000 to 1200 mm, and can be stored or transported in a state where a plurality of sheets are stacked. The synthetic resin material constituting the synthetic resin sheet 1 is made of polypropylene resin as described above, and is bent into a shape in which the ridges 1a and the ridges 1b are alternately repeated by vacuum molding, extrusion molding, press molding, injection molding, or the like. The piping support material 10 as shown in the illustrated figure is obtained.

  An example in which piping for fluid such as refrigerant, hot water, cold water, and steam is piped on the ceiling wall surface or vertical wall surface of the building using the pipe support material 10 will be described. As shown in FIGS. 2 and 3, the ceiling wall (not shown) of the building has a suspension bolt 2, 2 and a C-type or L-type (C in the illustrated example) that is horizontally fixed to the lower end by nuts 2 a, 2 a. A so-called ductor comprising a support bracket 3 made of an angle material or a channel material is suspended. A U-bolt 4 (two in the illustrated example) can be attached to the support fitting 3, and a pipe support is provided by the suspension bolts 2 and 2 including the nut 2 a, the support bracket 3 and the U-bolt 4 including the nut 4 a. 5 is configured. The fluid pipe 6 is made of a copper pipe, a steel pipe, or the like, and is entirely covered with a heat insulating heat insulating material 7 made of a rubber foam (for example, one disclosed in Patent Document 3). As the heat insulating and heat insulating material 7, in addition to such a rubber-based foam, a synthetic resin foam (for example, foamed polystyrene, foamed urethane, or the like) can be employed.

  When the pipe 6 for fluid covered with the heat insulating heat insulating material 7 is piped by the pipe support 5 as described above, first, the pipe support material 10 shown in FIG. In such a manner, cutting is performed at an appropriate dimension position along the length L direction. As shown in FIGS. 2 and 3, the pipe support member 10 that is cut and prepared is supported by the pipe support 5 so that the repeating direction of the ridges 1 a and the ridges 1 b extends along the circumferential direction of the heat insulating and heat insulating material 7. It winds around the peripheral surface of the heat insulation heat insulating material 7 of the site | part to make, and fixes the both ends to the heat insulation heat insulating material 7 with the adhesive tape 8 reliably. Next, the portion around which the pipe support member 10 is wound is placed on the support fitting 3, the U bolt 4 is held on the peripheral surface of the pipe support member 10 from above, and the nut 4 a is attached from below the support fitting 3 to the U bolt 4. Threaded onto. The nut 4a is screwed with a tightening force that suppresses the lifting of the pipe and does not apply a tightening load to the pipe. Such support and fixing are sequentially performed, and piping for the fluid piping 6 covered with the heat insulating and heat insulating material 7 is performed at a predetermined position on the building wall surface or the like.

  In place of the adhesive tape 8, an adhesive may be used, or the piping support material 10 may be fixed to the heat insulating and heat insulating material 7 by another binding band or the like. Further, in the illustrated example, the pipe support material 10 that has been cut and prepared has a size that can be wound around the entire circumference of the heat insulation and heat insulation material 7, but is addressed to at least the lower half of the heat insulation heat insulation material 7, The size may be such that it can be interposed between the support fitting 3 and the support metal fitting 3.

  In such a pipe support structure with the pipe support 5, the pipe support material 10 is interposed between the support fitting 3 and the heat insulating and heat-insulating material 7. Due to the material function, the heat insulating and heat insulating material 7 is not crushed and deformed by its own weight of the fluid pipe 6, and the heat insulating and heat insulating function of the heat insulating and heat insulating material 7 is maintained for a long time. Moreover, since the piping support material 10 consists of the synthetic resin sheet | seat 1 bent and formed in the shape where the protruding item | line 1a ... of a rectangular-shaped cross section and the concave item 1b ... repeat alternately, it was wound around the heat insulation heat insulating material 7. In the state, the boundary 1c of the ridges 1a and 1b is directed in the centripetal direction (radial direction) of the fluid pipe 6. Therefore, the rib effect by this boundary part 1c is exhibited in the part interposed between the support metal fitting 3 and the heat insulation heat insulating material 7, and the pipe support material 10 is buckled by the own weight of the fluid pipe 6 and the heat insulation heat insulating material 7. Is effectively prevented and the support function is maintained for a long time. Furthermore, since a space is formed between the heat insulating material 7 and the support fitting 3 by the ridges 1a... And the ridges 1b, the occurrence of condensation is also suppressed.

  Moreover, since the piping support material 10 consists of the synthetic resin sheet | seat 1, it is provided with a flexibility by elasticity peculiar to synthetic resin. Therefore, even if it is flat, it can be addressed along the peripheral surface of the heat insulation material 7 while being bent by on-site construction. If it is prepared as a standard one as shown in FIG. It can cut | disconnect to the magnitude | size according to the diameter of the heat insulation heat insulating material 7, and can use for piping construction. Therefore, it is not necessary to prepare a pipe structure of a size corresponding to various specification diameters, and since it is lightweight, it is excellent in handling properties such as storage and transportation. The thickness d of the synthetic resin sheet 1 is 0.5 to 1.5 mm, the height of the ridges 1a (depth of the ridges 1b) h is 4 to 6 mm, and the widths D1 and D2 of the ridges 1a and 1b. By setting the length to 5 to 7 mm, the suitability as the pipe support material is further improved as described above.

  4A, 4B, and 4C show modified examples of the cross-sectional shape of the pipe support material 10. FIG. The example of (a) shows a so-called folded plate shape, the example of (b) shows a waveform shape, and the example of (c) shows another modification of the waveform shape. These examples may be slightly inferior in buckling resistance as compared with the examples of FIGS. 1 to 3, but have equivalent characteristics by selecting the pitch and material of the ridges 1a and 1b. Can be. Moreover, since the flexibility is superior to that of the example of FIGS. 1 to 3, the workability is good, and these are appropriately selected and adopted according to the characteristics such as the weight of the target piping structure.

  The form of the pipe support 5 is not limited to a ductor as shown in the figure, but is a well-known one such as one that can be mounted horizontally on the vertical wall surface in the form of an arm, or one that supports the pipe vertically along the vertical wall surface. Can be employed. Further, it goes without saying that a band, an insulation lock or the like can be appropriately employed as the fixture instead of the U bolt 4. Furthermore, the shape that the ridges and the ridges repeat is not limited to those illustrated, and other shapes can also be appropriately employed.

It is a partially broken perspective view which shows an example of the piping support material of this invention. It is a vertical front view which shows the piping support structure using the piping support material. FIG. 3 is a cross-sectional view taken along line XX in FIG. 2. (A) (b) (c) is sectional drawing which shows notionally the modification of a piping support material.
