Piping support device
[0001] One embodiment of the present invention relates to a pipe support device.
[0002] Piping is one method for transporting fluids. When fluid flows inside a pipe, weight and temperature changes occur, causing the pipe to move. A pipe support device follows this movement while generating a certain reaction force. For example, the pipe support device disclosed in Patent Document 1 has a configuration in which springs are arranged above and below the pipe as elastic bodies.

[0008] Hereinafter, each embodiment of the invention disclosed in this application will be described with reference to the drawings. However, the present invention can be embodied in various forms without departing from the spirit of the invention, and should not be construed as being limited to the description of the embodiments exemplified below.
[0009] In order to clarify the description, the drawings may show the width, thickness, shape, etc. of each part schematically compared to the actual embodiment, but these are merely examples and do not limit the interpretation of the present invention. Furthermore, in this specification and each drawing, elements having the same functions as those explained in the previous drawings may be assigned the same reference numerals, and duplicate explanations may be omitted.
[0010] In this specification and drawings, the same reference numeral is used to collectively represent multiple identical or similar components, and a hyphen and a number are added after the reference numeral to represent each of the components individually. When multiple parts of a single component are to be distinguished from one another, the same reference numeral and alphabetic characters are used.
[0011] In this specification and claims, "integrated" means that the elements have different functions but are formed from a single member and have a continuous structure. Therefore, the integrated elements contain the same material and have the same composition.
[0012] First Embodiment A pipe support device 100 according to one embodiment of the present invention will be described below. The pipe support device 100 supports pipes and has a function of following the movement of the pipes due to changes in heat or weight. For convenience, in the drawings used in the following description, the vertical direction is defined as the z direction, and a horizontal plane perpendicular to the z direction is defined as the xy plane. The x and y directions are orthogonal to the z direction.
[0013] 1. Overall Structure A perspective view of the piping support device 100 is shown in FIG. 1. The piping support device 100 basically comprises a pair of hanger plates 102, a spring seat 106, at least one spring 108, a plurality of support frames 110, and a turnbuckle 116. These components are formed using metal such as iron or stainless steel. These components will be described in detail below.
[0014] 1-1. Hanger Plates A pair of hanger plates 102, including a first hanger plate 102-1 and a second hanger plate 102-2, is configured to suspend the piping support device 100, which includes the spring seat 106, the spring 108, the support frame 110, and the turnbuckle 116. The pair of hanger plates 102 are fixed so that their main surfaces face each other and are parallel to the z direction. The hanger plates 102 may be fixed to each other by any method, for example, using bolts 130 and nuts 132. Each of the pair of hanger plates 102 may be provided with an opening 102a for suspending the piping support device 100 from a support or the like. The openings 102a are arranged to overlap each other in a direction perpendicular to the z direction (the y direction in the example of FIG. 1). Although not shown, the pair of hanger plates 102 may be integrated into a single structure.
[0015] 1-2. Spring Seat The spring seat 106 is a plate-shaped member located below the hanger plate 102, partially overlapping the hanger plate 102, and is arranged so that its main surface is parallel or substantially parallel to the x-y plane. As can be seen from the schematic top view of the spring seat 106 shown in FIG. 2, the spring seat 106 includes a center portion 106a, indicated by a dashed line, that overlaps with the spring 108, and a pair of end portions 106b that sandwich the center portion 106a. The end portions 106b protrude from the center portion 106a in the x-y plane and face each other across the center portion 106a. Therefore, the end portions 106b do not overlap with the spring 108 in the z direction. As will be described in detail later, the support frame 110 restricts the movement of the spring 108 in the x-y plane. Therefore, there is no need to provide a structure (such as unevenness or ribs) on the lower surface of the spring seat 106 to prevent movement of the spring 108, and the lower surface may be flat over the entire spring seat 106. Hereinafter, the direction in which the end portion 106b extends from the center portion 106a is referred to as the x direction.
[0016] 1-3. Support Frame The piping support device 100 is provided with two or more support frames 110. There is no restriction on the number of support frames 110, but for example, as shown in Fig. 1, the multiple support frames 110 may include four support frames 110. Below, the explanation will continue using an example in which the multiple support frames 110 include first to fourth support frames 110-1 to 110-4.
[0017] Each of the multiple support frames 110 is connected to and fixed to one of the pair of hanger plates 102. In the example shown in FIG. 1 , the first support frame 110-1 and the second support frame 110-2 are connected to and fixed to the first hanger plate 102-1 and extend downward (i.e., in the z-direction) from the first hanger plate 102-1. The first support frame 110-1 and the second support frame 110-2 may be connected to and fixed to the first hanger plate 102-1 by welding, bolting, or the like, or may be integrated with the first hanger plate 102-1. Similarly, the third support frame 110-3 and the fourth support frame 110-4 are connected to and fixed to the second hanger plate 102-2 and extend downward from the second hanger plate 102-2. The third support frame 110-3 and the fourth support frame 110-4 may also be connected or fixed to the second hanger plate 102-2 by welding, bolting, etc., or may be integrated with the second hanger plate 102-2. The first support frame 110-1 and the third support frame 110-3, and the second support frame 110-2 and the fourth support frame 110-4 are fixed to each other using, for example, bolts 134 and nuts 136.
[0018] The multiple support frames 110 are arranged to surround a portion of the spring seat 106 and the spring 108. More specifically, as shown in FIG. 2 , the multiple support frames 110 surround the spring 108 in the xy plane and also surround the center portion 106a of the spring seat 106. Furthermore, the multiple support frames 110 are arranged to sandwich the end portion 106b of the spring seat 106. In the example shown in FIG. 2 , the first support frame 110-1 and the third support frame 110-3 face each other in the y direction via one end portion 106b. Similarly, the second support frame 110-2 and the fourth support frame 110-4 face each other in the y direction via the other end portion 106b. Therefore, in the y direction, one end 106b is sandwiched between the first support frame 110-1 and the third support frame 110-3, and the other end 106b is sandwiched between the second support frame 110-2 and the fourth support frame 110-4. Note that, although an example in which the end 106b contacts the support frame 110 is shown in FIG. 2, the width (length in the y direction) of the end 106b is determined by the distance d between the support frames 110 that sandwich it. 1 In this case, the spring seat 106 can be out of contact with the support frame 110.
[0019] 2, the length of the center portion 106a in the y direction is longer than the width (length in the y direction) of the end portion 106b. In addition, the distance d between the two support frames 110 that sandwich the spring seat 106 in the y direction, i.e., the two support frames 110 that sandwich one end portion 106b (for example, the first support frame 110-1 and the third support frame 110-3, or the second support frame 110-2 and the fourth support frame 110-4) is 1 is equal to or greater than the width of the end 106b, but is smaller than the length of the center 106a in the y direction. Therefore, the movement of the spring seat 106 in the xy plane is restricted by the support frames 110, and the spring seat 106 is allowed to slide in the z direction with the end 106b sandwiched between the pair of support frames 110.
[0020] Furthermore, the distance d between the two support frames 110 that hold one end 106b is 1The support frames 110 are arranged so that the outer diameter D of the spring 108 is smaller than the outer diameter D of the spring 108. At the same time, the distance d between the portions extending in the z direction of two support frames 110 overlapping in the x direction, that is, two support frames 110 sandwiching the center portion 106a (for example, the first support frame 110-1 and the second support frame 110-2, or the third support frame 110-3 and the fourth support frame 110-4) is 2 The support frames 110 are arranged so that the outer diameter D of the springs 108 is smaller than the outer diameter D of the springs 108. By adopting such an arrangement, the springs 108 cannot pass between adjacent support frames 110, and it is possible to prevent the springs 108 from falling off the piping support device 100.
[0021] As shown in FIG. 1 , the lower end of each support frame 110 is bent to have a hook shape. Specifically, as shown in FIGS. 3A and 3B , each support frame 110 is bent to have a first portion 110a extending in the z direction from the hanger plate 102 and surrounding the spring seat 106 and spring 108, a third portion 110c positioned inside the spring 108 and surrounded by the spring 108, and a second portion positioned between the first portion 110a and the third portion 110c and overlapping the spring 108 below. The second portion 110b supports the spring 108 and determines the position of the lower end of the spring 108. As will be described in detail later, this hook shape catches the lower end of the spring 108, stabilizing the behavior of the spring 108.
[0022] 1-4. Spring and turnbuckle The spring 108 is disposed between the second portion 110b of the support frame 110 and the spring seat 106 so that its central axis (hereinafter referred to as the spring axis) is in the z direction. Although the spring 108 is sandwiched between the second portion 110b and the spring seat 106, there is no need to weld or bolt them to them.
[0023] 4 and 5 show schematic side views of the piping support device 100. The turnbuckle 116 is arranged so that its longitudinal direction faces the z-direction, and its upper end is suspended from the spring seat 106 via a shaft 118. The shaft 118 may be welded to the spring seat 106, or as shown in FIGS. 5 and 6, a bolt passing through the spring seat 106 may be used as the shaft 118. The turnbuckle 116 is arranged so as to be surrounded by the spring 108 while suspended from the spring seat 106.
[0024] A piping fixture 150 that fixes a pipe 152 to the turnbuckle 116 is connected to the lower end of the turnbuckle 116. Any method can be used to connect the turnbuckle 116 and the piping fixture 150, and for example, the turnbuckle 116 and the piping fixture 150 can be connected by bolting or the like using an opening 116a (see FIG. 1) provided at the lower end of the turnbuckle 116.
[0025] Typically, when connecting the pipe 152, the pipe support device 100 is hung from a support or the like using the opening 102a, and in this state, the pipe 152 is attached to the turnbuckle 116 via the pipe fixture 150. At this time, if the length of the spring 108 is at its natural length, the weight of the pipe 152 and the pipe fixture 150 causes the spring 108 to contract, which in turn causes the turnbuckle 116, the pipe fixture 150 attached thereto, and the pipe 152 to move downward. If such movement occurs, the pipe 152 will be positioned in a state that is shifted downward from its predetermined position. Therefore, it is preferable to set (preset) the spring 108 to a compressed state in advance so that the restoring force of the spring 108 will not cause the turnbuckle 116 to move in the z direction even when the pipe 152 and the pipe fixture 150 are connected.
[0026] Therefore, the piping support device 100 may further include a pair of fixing plates 114 sandwiching the multiple support frames 110 as a configuration for presetting the springs 108 ( FIG. 6 ). There are no limitations on the shape or structure of the fixing plates 114, as long as they are configured to fix the distance between the spring seat 106 and the support frame 110 and / or the hanger plate 102. For example, as shown in FIG. 6 , the fixing plate 114 may be a plate-like member having openings 114a and 114b through which at least one of the pair of hanger plates 102 and the end 106b of the spring seat 106 pass. In the example shown in FIG. 6 , the pair of hanger plates 102 simultaneously pass through the opening 114a. By appropriately adjusting the distance between the openings 114a and 114b, the springs 108 can be accommodated at any length between the second portion 110b of the support frame 110 and the spring seat 106. Therefore, the pipe 152 and the pipe fixing device 150 are connected to the turnbuckle 116 using the fixing plate 114 while maintaining an appropriate compressed state taking into account the weight of the pipe 152 and the pipe fixing device 150, and then the fixing plate 114 is removed, thereby allowing the pipe 152 to be positioned in the specified position.
[0027] When a fluid flows through the pipe 152, a downward force is applied to the pipe 152 due to the weight of the fluid, which results in a downward pull on the turnbuckle 116. When the spring seat 106 moves downward in response to this, the restoring force of the spring 108 increases, as shown in FIG. 7, and an upward force is applied, allowing a constant restoring force to be added.
[0028] When the spring 108 expands or contracts, a force is also applied to the spring 108 that rotates around the spring axis extending in the z direction, which may cause the spring 108 to move within the xy plane. Such movement may cause the spring 108 to fall off. Furthermore, depending on the number of turns, pitch, length, coil diameter, center diameter, etc. of the spring 108, buckling may occur during the expansion or contraction process. However, as described above, if the distance d between the two support frames 110 is 1 and d 2(See FIGS. 3A and 3B.) The support frames 110 are arranged so that the outer diameter D of the springs 108 is smaller than the outer diameter D of the springs 108, thereby preventing bending or buckling of the springs 108. Furthermore, each support frame 110 has a third portion 110c that is surrounded by the springs 108. This prevents the springs 108 from falling off even if the springs 108 move in the xy plane.
[0029] The piping support device 100 having the above configuration can effectively prevent the spring 108 from falling off or buckling without using a cover or the like to cover the side of the spring 108. This allows for a reduction in the weight of the piping support device 100 while ensuring high breathability for the spring 108 and the turnbuckle 116 disposed therein. As a result, corrosion caused by rainwater accumulation and the like can be significantly suppressed, improving the durability of the piping support device 100. Furthermore, since almost the entire spring 108 and turnbuckle 116 can be visually inspected from the outside, the condition of the spring 108 and turnbuckle 116 can be easily grasped. Therefore, damage to each part, such as the spring 108 or turnbuckle 116, can be detected early. This simplifies maintenance work and contributes to more efficient maintenance work. Furthermore, the piping support device 100 can be connected and fixed using only bolts without welding, allowing for low-cost manufacturing.
[0030] 2. Modifications 2-1. Modification 1 The structure of the piping support device 100 is not limited to the structure described above. For example, as shown in FIGS. 8 to 9B , a pair of guide rods 112 may be provided to more precisely control the position of the spring seat 106. In this case, for example, a cover plate 104 may be provided to connect the pair of hanger plates 102, and the guide rod 112 may be fixed to the cover plate 104 so as to extend downward from the cover plate 104. For example, as shown in FIGS. 8 to 9B , the cover plate 104 is fixed onto the hanger plate 102. Fixing may be performed by welding or bolting. The guide rod 112 is a bolt having a head 112 a at its upper end, and its threaded portion is provided with a thread (not shown). The cover plate 104 has an opening through which the threaded portion of the guide rod 112 passes but which the head 112 a does not pass through. By inserting the guide rods 112 into these openings and fixing them with nuts 120, the cover plate 104 and the guide rods 112 are fixed to each other with the guide rods 112 extending downward (in the z direction) from the cover plate 104. The direction connecting the central axes of the pair of guide rods 112 extending in the z direction and perpendicular to the z direction is the x direction.
[0031] Each of the pair of end portions 106b of the spring seat 106 is provided with a pair of notches that sandwich the guide rod 112. Although not shown, instead of the pair of notches, the end portion 106b may be provided with a pair of openings through which the guide rod 112 can be inserted. As an optional configuration, a socket head bolt 124 and a nut 126 may be attached to the notch or opening of the spring seat 106 so as to sandwich the spring seat 106. Washers are inserted between the socket head bolt 124 and the spring seat 106 and between the nut 126 and the spring seat 106 as appropriate. The socket head bolt 124 and the nut 126 surround the guide rod 112 but slide on the guide rod 112. Therefore, the spring seat 106 can reversibly slide in the z-direction (i.e., up and down) along the guide rod 112 in response to the vertical movement of the piping, i.e., the vertical movement of the turnbuckle 116, without coming off the guide rod 112. Each guide rod 112 may be provided with two nuts 122, 128, one above the other, that engage with the threads of the screw. The positions of the nuts 122, 128 in the z direction are determined by rotating them around the guide rod 112. Therefore, the initial position of the spring seat 106 can be determined by adjusting the positions of the nuts 122, 128.
[0032] 10, a single cover plate 104 may be connected to the hanger plate 102. In this case, there is no need to provide an opening 102a in the hanger plate 102, and instead, a hanging ring 138 may be disposed on the cover plate 104. The guide rod 112 is provided to extend downward from one cover plate 104.
[0033] 2-3. Modification 3 As described above, in the example shown in FIG. 1 and the like, the piping support device 100 is provided with at least one spring 108, but this at least one spring 108 may include multiple springs 108. Specifically, as shown in FIG. 11 , multiple springs (here, a first spring 108-1 and a second spring 108-2) overlapping each other in the z direction may be provided between the third portion 110c of the support frame 110 and the spring seat 106. In this case, an intermediate ring 109 having an opening through which the shaft 118 can pass may be disposed between adjacent springs 108. By providing multiple springs 108, it is possible to accommodate locations where the amount of piping movement is large.
[0034] In the above-described modified example, the support frame 110 also restricts the movement of the spring 108 in the xy plane, and it is possible to effectively prevent the spring 108 from falling off or buckling while allowing the spring 108 to slide in the z direction without using a cover or the like to cover the side surface of the spring 108. This contributes to reducing the weight of the piping support device, reducing manufacturing costs, and easing the burden of maintenance work.
[0035] Second Embodiment In this embodiment, a pipe support device 160 having a structure different from that of the pipe support device 100 described in the first embodiment will be described. Descriptions of configurations that are the same as or similar to those described in the first embodiment may be omitted.
[0036] A schematic perspective view of the piping support device 160 is shown in Fig. 12, and side views thereof are shown in Fig. 13 and Fig. 14. As shown in these figures, the piping support device 160 basically includes a base plate 146, at least one spring 108, a spring seat 106, a hanger plate 102, a plurality of support frames 142, and a turnbuckle 116. The piping support device 160 may further include a first band plate 140 and a second band plate 144 as an optional configuration.
[0037] 1. Hanger Plate Schematic top views of the piping support device 160 are shown in Figures 15A and 15B. In Figure 15B, the hanger plate 102 is shown with a dotted line for ease of viewing. The hanger plate 102 is configured to suspend the piping support device 160, which includes the base plate 146, spring 108, spring seat 106, support frame 142, and turnbuckle 116. To achieve the above function, a hanging ring 138 is provided on the upper surface of the hanger plate 102. The shape of the hanger plate 102 in the xy plane can be determined arbitrarily. As shown in Figure 15B, the shape of the hanger plate 102 in the xy plane may be a cross shape, or, although not shown, may be a polygon, including a square or rectangle.
[0038] 2. Base Plate Schematic top and bottom views of the piping support device 160 are shown in Figures 16A and 16B, respectively. For ease of viewing, the hanger plate 102, spring seat 106, and the like are not shown in Figure 16A. The base plate 146 is a part that functions to support the spring 108, and as shown in Figures 16A and 16B, has a through hole 146a through which the turnbuckle 116 can pass, and is configured so that its upper surface overlaps the spring 108. As shown in Figure 16B, the base plate 146 may also have a cross shape, but as long as it can exhibit the above function, its shape is arbitrary, and it may be a polygon including a square or rectangle, a circle, or an ellipse.
[0039] 3. Spring Seat The spring seat 106 is located between the spring 108 and the hanger plate 102, and at least a portion of the spring seat 106 overlaps with the hanger plate 102. The configuration of the spring seat 106 of the piping support device 160 is similar to the spring seat 106 of the piping support device 100 described in the first embodiment, and therefore a detailed description thereof will be omitted.
[0040] 4. Support Frames The multiple support frames 142 extending in the z direction have the function of suppressing movement of the springs 108 in the xy plane and preventing buckling. There is no restriction on the number of the multiple support frames 110, but for example, as shown in Figures 12 to 15B, the multiple support frames 142 may include first to fourth support frames 142-1 to 142-4. The following description will continue using an example in which the multiple support frames 142 include first to fourth support frames 142-1 to 142-4.
[0041] In the example shown in these figures, the length (length in the z direction) of each support frame 142 is longer than the distance between the base plate 146 and the hanger plate 102. Therefore, the multiple support frames 142 surround the base plate 146 and the hanger plate 102, and the upper and lower ends of each support frame 142 are above the base plate 146 and below the hanger plate 102. However, the length of each support frame 142 may be the same as the distance between the base plate 146 and the hanger plate 102. In this case, the multiple support frames 142 may be arranged so as to be sandwiched between the base plate 146 and the hanger plate 102. The support frames 142 are fixed to the hanger plate 102 and the base plate 146 by welding or bolting.
[0042] Similar to the support frame 110 of the piping support device 100, the support frame 142 of the piping support device 160 is also disposed so as to surround a portion of the spring seat 106 and the spring 108. More specifically, the multiple support frames 142 surround the spring 108 in the xy plane and also surround the center 106a of the spring seat 106. Furthermore, the first support frame 142-1 and the third support frame 142-3 face each other in the y direction via one end 106b and a portion of the center 106a. Similarly, the second support frame 142-2 and the fourth support frame 142-4 face each other in the y direction via the other end 106b and a portion of the center 106a. Therefore, in the y direction, one end 106b is sandwiched between the first support frame 142-1 and the third support frame 142-3, and the other end 106b is sandwiched between the second support frame 142-2 and the fourth support frame 142-4. Furthermore, the center portion 106a is sandwiched between two arbitrarily selected support frames 142 (see FIG. 15B). Note that, although the support frames 142 do not contact the spring seat 106 in FIG. 15B, the support frames 142 and the spring seat 106 may be configured so that at least one of the support frames 142 contacts the spring seat 106.
[0043] Here, as shown in FIG. 16A, the distance d in the xy plane between two adjacent support frames 142 in the x or y direction is 3 The support frames 142 are arranged so that the outer diameter D of the spring 108 is smaller than the outer diameter D of the spring 108. The distance in the x direction between two support frames 142 adjacent in the x direction (for example, the first support frame 142-1 and the second support frame 142-2, or the third support frame 142-3 and the fourth support frame 142-4) and the distance d in the y direction between two support frames 142 adjacent in the y direction (for example, the first support frame 142-1 and the third support frame 142-3, or the second support frame 142-2 and the fourth support frame 142-4) are 3 By adopting such an arrangement, the spring 108 cannot pass between adjacent support frames 142, and as a result, it is possible to prevent the spring 108 from falling off the piping support device 160.
[0044] The shape of the support frame 142 (shape in the xy plane) can also be determined arbitrarily, and may be, for example, an L-shape as shown in Figures 15A to 16B, or may be a circle, ellipse, or rectangle (not shown). In the case of an L-shape, the support frame 142 is preferably formed of angle iron and arranged so that its inner side (acute angle side) faces the spring 108. By arranging the L-shaped support frame 142 in this way, the distance d 3 can be made smaller, so that the movement of the spring 108 in the xy plane can be more effectively suppressed.
[0045] 5. Spring and Turnbuckle The spring 108 and the turnbuckle 116 can have the same configuration as the spring 108 and the turnbuckle 116 of the pipe support device described in the first embodiment, respectively, and therefore a detailed description thereof will be omitted. Note that in the example shown in Fig. 12 etc., at least one spring 108 includes a plurality of springs 108, and adjacent springs 108 are stacked one above the other with intermediate rings 109 interposed therebetween, but there is no restriction on the number of springs 108, and it may be one, or three or more.
[0046] 6. Other Configurations The first band plate 140 is disposed on the second band plate 144 and fixed to a plurality of support frames 142 by welding or bolting. As shown in FIGS. 12 to 14 , the first band plate 140 can be disposed on the hanger plate 102. In this case, openings are provided to expose the hanging rings 138. If the upper ends of the support frames 142 are positioned above the hanger plate 102, the support frames 142 pass through these openings. The first band plate 140 may also be positioned below the hanger plate 102. The first band plate 140 and the hanger plate 102 may be in contact with each other or spaced apart. In the former case, the first band plate 140 and the hanger plate 102 are fixed to each other by welding or bolting.
[0047] The second band plate 144 is disposed below the first band plate 140 and fixed to the support frame 142 by welding or bolting. As shown in Figures 12 to 14, the second band plate 144 can be disposed above the base plate 146, but the second band plate 144 may also be disposed below the base plate 146. Furthermore, the second band plate 144 and the base plate 146 may be in contact with each other or may be spaced apart. In the former case, the second band plate 144 and the base plate 146 are fixed to each other by welding or bolting.
[0048] Since the support frame 142 is surrounded by the first band plate 140 and the second band plate 144, the provision of the first band plate 140 and the second band plate 144 allows the support frame 142 to be more securely fixed to the hanger plate 102 and the base plate 146.
[0049] In the piping support device 160 having the above configuration, the end 106b of the spring seat is also sandwiched between the adjacent support frames 142. Therefore, the support frames 142 act as a guide, and the spring seat 106 can slide up and down along the support frames 142 as the spring 108 expands and contracts. Note that, similar to the piping support device 100, the piping support device 100 may also be formed with a pair of guide rods 112. In this case, as shown in FIG. 17 , the pair of guide rods 112 are attached to the hanger plate 102 and are arranged to extend downward from the hanger plate 102. The configuration of the guide rods 112 is the same as that of the piping support device 100, so a detailed description thereof will be omitted.
[0050] As with the piping support device 100, a pair of fixing plates 114 may be provided to sandwich a plurality of support frames 142 in order to preset the springs 108 ( FIG. 18 ). Each fixing plate 114 is provided with an opening through which the spring seat 106 passes and an opening through which the hanger plate 102 passes. When the first band plate 140 is provided, the opening through which the hanger plate 102 passes may be configured so that the first band plate 140 also passes through at the same time.
[0051] In the pipe support device 160, the turnbuckle 116 and the spring seat 106 vibrate up and down due to changes in the mass of the fluid transported through the pipe 152, causing the spring 108 to expand and contract. As a result, a force that rotates the spring 108 about the spring axis is also applied to the spring 108, which may cause the spring 108 to move within the x-y plane. Furthermore, buckling may occur when the spring 108 expands or contracts. However, as described above, the pipe support device 160 is provided with a support frame 142 that prevents the spring 108 from falling off, thereby effectively preventing the spring 108 from falling off. Furthermore, the support frame 142 suppresses deformation of the spring 108 other than expansion and contraction, thereby effectively preventing buckling.
[0052] As with the piping support device 100, the piping support device 160 can also effectively prevent the springs 108 from falling off or buckling without using a cover or the like to cover the sides of the springs 108. This contributes to reducing the weight of the piping support device, reducing manufacturing costs, and easing the burden of maintenance work.
[0053] The above-described embodiments of the present invention may be combined as appropriate as long as they are not mutually inconsistent. Furthermore, even if a person skilled in the art adds or deletes components or modifies the design based on each embodiment, the addition, deletion, or modification of components is included in the scope of the present invention as long as the gist of the present invention is maintained.
[0054] Furthermore, even if there are other effects and advantages different from those brought about by the above-mentioned embodiments, those that are clear from the description in this specification or that can be easily predicted by a person skilled in the art are naturally understood to be brought about by the present invention.
