[Modes for carrying out the invention] 【0008】 Hereinafter, embodiments of the invention disclosed in this application will be described with reference to the drawings. However, the present invention can be implemented in various forms without departing from its spirit, and is not construed to be limited to the embodiments described below. 【0009】 While drawings may schematically represent the width, thickness, shape, etc., of each part compared to the actual embodiment in order to clarify the explanation, 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 function as those described in previously shown drawings are denoted by the same reference numerals, and redundant explanations may be omitted. 【0010】 In this specification and the drawings, when collectively representing a plurality of identical or similar components, the same reference numerals are used, and when individually representing them, a hyphen and a number are appended after the reference numerals. When distinguishing and representing a plurality of parts within one component, the same reference numerals are used, and furthermore, alphabet letters are used. 【0011】 In this specification and the claims, the integration of a plurality of elements means that although the plurality of elements have different functions from each other, they are formed from one member and have a continuous configuration. Therefore, the integrated plurality of elements contain the same material as each other and have the same composition. 【0012】 <First Embodiment> Hereinafter, a pipe support device 100, which is one of the embodiments of the present invention, will be described. The pipe support device 100 supports a pipe and has a function of following the movement of the pipe due to changes in heat and weight. In the drawings used in the following description, for the sake of convenience, the vertical direction is taken as the z direction, and the horizontal plane perpendicular to the z direction is taken as the xy plane. The x direction and the y direction are orthogonal to the z direction. 【0013】 1. Overall Structure A perspective view of the pipe support device 100 is schematically shown in FIG. 1. The pipe support device 100 basically includes a pair of hanger plates 102, spring seats 106, at least one spring 108, a plurality of support frames 110, and a turnbuckle 116. These components are formed using metals such as iron and stainless steel. Hereinafter, these components will be described in detail. 【0014】 1-1. Hanger Plate A pair of hanger plates 102, including the first hanger plate 102-1 and the second hanger plate 102-2, are configured to suspend a pipe support device 100, which includes a spring seat 106, a spring 108, a support frame 110, and a turnbuckle 116. The pair of hanger plates 102 are fixed so that their main surfaces face each other with their main surfaces parallel to the z-direction. The method of fixing the hanger plates 102 together is arbitrary, but for example, it can be done using bolts 130 and nuts 132. Each of the pair of hanger plates 102 may be provided with an opening 102a for suspending the pipe support device 100 from a support column or the like. The openings 102a are provided so that they overlap each other in a direction perpendicular to the z-direction (y-direction in the example of Figure 1). Although not shown, the pair of hanger plates 102 may be a single integrated configuration. 【0015】 1-2. Spring constellation The spring seat 106 is located below the hanger plate 102 and is a plate-like member that partially overlaps with the hanger plate 102, with its main surface positioned parallel or substantially parallel to the xy plane. As can be seen from the schematic top view of the spring seat 106 shown in Figure 2, the spring seat 106 includes a central part 106a that overlaps with the spring 108, indicated by the dashed line, and a pair of ends 106b that sandwich the central part 106a. The ends 106b are portions that protrude from the central part 106a in the xy plane and face each other via the central part 106a. For this reason, the ends 106b do not overlap with the spring 108 in the z direction. As will be described in detail later, the movement of the spring 108 in the xy plane is restricted by the support frame 110. For this reason, it is not necessary to provide a structure (such as bumps or ribs) on the lower surface of the spring seat 106 to prevent the movement of the spring 108, and the lower surface may be flat over the entire spring seat 106. Hereafter, the direction in which the end portion 106b extends from the central portion 106a will be referred to as the x-direction. 【0016】 1-3. Support Frame In the pipe support device 100, two or more support frames 110 are provided. There is no restriction on the number of support frames 110, but as shown in Figure 1, for example, there can be four support frames 110. The following explanation will continue using an example in which the multiple support frames 110 include the first to fourth support frames 110-1 to 110-4. 【0017】 Each of the support frames 110 is connected to and fixed to one of the pair of hanger plates 102. In the example shown in Figure 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 other means, or they 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 also 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 to and fixed to the second hanger plate 102-2 by welding or bolting, or they 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, for example, using bolts 134 and nuts 136. 【0018】 Multiple support frames 110 are arranged to surround a portion of the spring seat 106 and the spring 108. More specifically, as shown in Figure 2, the multiple support frames 110 surround the spring 108 in the xy plane and surround the central part 106a of the spring seat 106. Furthermore, the multiple support frames 110 are arranged to sandwich the end 106b of the spring seat 106. In the example shown in Figure 2, the first support frame 110-1 and the third support frame 110-3 face each other in the y direction via one end 106b. Similarly, the second support frame 110-2 and the fourth support frame 110-4 also face each other in the y direction via the other end 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. Although Figure 2 shows an example where the end 106b is in contact with the support frame 110, the width (length in the y-direction) of the end 106b may be shorter than the distance d1 between the support frames 110 that sandwich it. In this case, the spring seat 106 can be in a state where it is not in contact with the support frame 110. 【0019】 Here, as shown in Figure 2, the length of the central part 106a in the y-direction is longer than the width (length in the y-direction) of the end part 106b. Also, the distance d1 between the two support frames 110 that clamp the spring seat 106 in the y-direction, that is, the two support frames 110 that clamp one end part 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 greater than or equal to the width of the end part 106b, but smaller than the length of the central part 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 sliding of the spring seat 106 in the z-direction is permitted while the end part 106b is clamped between the pair of support frames 110. 【0020】 Furthermore, the support frames 110 are arranged such that the distance d1 between the two support frames 110 that clamp one end 106b is smaller than the outer diameter D of the spring 108. At the same time, the support frames 110 are also arranged such that the distance d2 between the z-extending portions of two support frames 110 that overlap in the x-direction, i.e., two support frames 110 that clamp the center 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 also smaller than the outer diameter D of the spring 108. By adopting this arrangement, the spring 108 cannot pass between adjacent support frames 110, and the spring 108 can be prevented from falling off the pipe support device 100. 【0021】 As shown in Figure 1, the lower end of each support frame 110 is bent to form a hook shape. Specifically, as shown in Figures 3(A) and 3(B), each support frame 110 is bent to have a first portion 110a that extends in the z direction from the hanger plate 102 and surrounds the spring seat 106 and spring 108, a third portion 110c that is positioned inside the spring 108 and surrounded by the spring 108, and a second portion that is located between the first portion 110a and the third portion 110c and overlaps with the spring 108 on its underside. The spring 108 is supported by the second portion 110b, and the position of the lower end of the spring 108 is determined. As will be described in more detail later, this hook shape allows the lower end of the spring 108 to catch, stabilizing the behavior of the spring 108. 【0022】 1-4. Springs and Turnbuckles The spring 108 is positioned between the second portion 110b of the support frame 110 and the spring seat 106 such 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 it to them. 【0023】 Figures 4 and 5 show schematic side views of the pipe support device 100. The turnbuckle 116 is positioned with its longitudinal direction facing 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 Figures 5 and 6, a bolt passing through the spring seat 106 may be used as the shaft 118. The turnbuckle 116 is positioned so as to be surrounded by the spring 108 while suspended from the spring seat 106. 【0024】 A pipe fixing device 150 for securing the pipe 152 to the turnbuckle 116 is connected to the lower end of the turnbuckle 116. The method of connecting the turnbuckle 116 and the pipe fixing device 150 is arbitrary; for example, the turnbuckle 116 and the pipe fixing device 150 can be connected by bolting or other means using the opening 116a (see Figure 1) provided at the lower end of the turnbuckle 116. 【0025】 Normally, when connecting the pipe 152, the pipe support device 100 is suspended from a support column or the like using the opening 102a, and in this state, the pipe 152 is attached to the turnbuckle 116 via the pipe fixing device 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 fixing device 150 will cause the spring 108 to contract, and consequently, the turnbuckle 116, the pipe fixing device 150 attached to it, and the pipe 152 will move downward. If such movement occurs, the pipe 152 will be positioned shifted downward from its predetermined position. Therefore, it is preferable to pre-set the spring 108 to a compressed state so that the turnbuckle 116 does not move in the z direction due to the restoring force of the spring 108 even when the pipe 152 and the pipe fixing device 150 are connected. 【0026】 Therefore, the pipe support device 100 may further include a pair of fixing plates 114 that sandwich a plurality of support frames 110 as a configuration for presetting the spring 108 (Figure 6). There are no restrictions on the shape or structure of the fixing plates 114, as long as they are configured to have the function of fixing the distance between the spring seat 106 and the support frame 110 and / or hanger plate 102. For example, as shown in Figure 6, the fixing plate 114 may be a plate-shaped member having openings 114a, 114b through which at least one of the pair of hanger plates 102 and the end 106b of the spring seat 106 pass, respectively. In the example shown in Figure 6, the pair of hanger plates 102 pass through the opening 114a simultaneously. By appropriately adjusting the distance between the openings 114a and 114b, the spring 108 can be accommodated between the second portion 110b of the support frame 110 and the spring seat 106 at any length. Therefore, by using the fixing plate 114 to maintain an appropriate compression state that takes into account the weight of the pipe 152 and pipe fixing device 150, the pipe 152 and pipe fixing device 150 can be connected to the turnbuckle 116, and then the fixing plate 114 can be removed to position the pipe 152 in the predetermined location. 【0027】 When fluid flows through pipe 152, the weight of the fluid exerts a downward force on pipe 152, causing the turnbuckle 116 to be pulled downward. As a result, the spring seat 106 moves downward, increasing the restoring force of the spring 108, as shown in Figure 7, and applying an upward force, thereby adding a constant restoring force. 【0028】 When spring 108 expands or contracts, a rotational force is also applied to it around its spring axis, which extends in the z direction. This can cause spring 108 to move in the xy plane. Such movement can lead to spring 108 falling off. Furthermore, depending on the number of turns, pitch, length, coil diameter, and center diameter of spring 108, buckling may occur during the expansion and contraction process. However, as described above, the support frames 110 are positioned such that the distances d1 and d2 between the two support frames 110 (see Figures 3(A) and 3(B)) are smaller than the outer diameter D of spring 108, thus preventing bending and buckling of spring 108. In addition, a third portion 110c surrounded by spring 108 is formed on each support frame 110. Therefore, even if spring 108 moves in the xy plane, it is prevented from falling off. 【0029】 In the pipe support device 100 having the above configuration, the spring 108 can be effectively prevented from falling off or buckling without the need for a cover to enclose its sides. This allows for a lighter pipe support device 100 while ensuring high ventilation for the spring 108 and the turnbuckle 116 located inside it. As a result, corrosion caused by rainwater accumulation can be significantly suppressed, improving the durability of the pipe support device 100. Furthermore, since almost the entire spring 108 and turnbuckle 116 can be visually inspected from the outside, their condition can be easily assessed. Therefore, damage to any part such as the spring 108 or turnbuckle 116 can be detected early. This enables easy maintenance work and contributes to increased efficiency in maintenance operations. In addition, since the pipe support device 100 can be connected and fixed using only bolts without welding, it can be manufactured at a low cost. 【0030】 2. Variations 2-1. Variation 1 The structure of the pipe support device 100 is not limited to the structure described above. For example, as shown in Figures 8 to 9(B), 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 connecting a pair of hanger plates 102 may be provided, and the guide rods 112 may be fixed to the cover plate 104 so as to extend downward from the cover plate 104. For example, as shown in the example in Figures 8 to 9(B), the cover plate 104 is fixed on the hanger plates 102. Fixing may be done by welding or bolting. The guide rod 112 is a bolt having a head 112a at its upper end, and its threaded portion is provided with a screw thread (not shown). The cover plate 104 is provided with an opening through which the threaded portion of the guide rod 112 passes, but through which the head 112a does not. By inserting the guide rod 112 into this opening and securing it with the nut 120, the cover plate 104 and the guide rod 112 are fixed to each other with the guide rod 112 extending downward (in the z direction) from the cover plate 104. The x direction is the direction that connects the central axes of the pair of guide rods 112 that extend in the z direction and is perpendicular to the z direction. 【0031】 Each of the pair of ends 106b of the spring seat 106 is provided with a pair of notches to sandwich the guide rod 112. Although not shown, instead of the pair of notches, a pair of openings into which the guide rod 112 can be inserted may be provided at the ends 106b. In an optional configuration, a bolt with a hole 124 and a nut 126 may be attached to the notches or openings of the spring seat 106 so as to sandwich the spring seat 106. Washers are inserted between the bolt with a hole 124 and the spring seat 106, and between the nut 126 and the spring seat 106 as appropriate. The bolt with a hole 124 and the nut 126 surround the guide rod 112, but slide along the guide rod 112. Therefore, the spring seat 106 can slide reversibly in the z direction (i.e., up and down) along the guide rod 112 as the piping moves vertically, i.e., the turnbuckle 116 moves vertically, without coming off the guide rod 112. Furthermore, each guide rod 112 may be provided with two nuts 122 and 128, one above and one below, that engage with the screw threads. The position of the nuts 122 and 128 in the z-direction is determined by rotating them around the guide rod 112. Therefore, the initial position of the spring seat 106 can be determined by adjusting the position of the nuts 122 and 128. 【0032】 2-2. Variation 2 Alternatively, as schematically shown in Figure 10, a single cover plate 104 may be connected to the hanger plate 102. In this case, it is not necessary to provide an opening 102a in the hanger plate 102; instead, the suspension ring 138 can be placed on top of the cover plate 104. The guide rod 112 is provided to extend downward from one of the cover plates 104. 【0033】 2-3. Variation 3 As described above, in the example shown in Figure 1, the pipe 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 Figure 11, multiple springs that overlap each other in the z direction (here, a first spring 108-1 and a second spring 108-2) may be provided between the third part 110c of the support frame 110 and the spring seat 106. In this case, an intermediate ring 109 having an opening through which a shaft 118 can pass may be placed between adjacent springs 108. By providing multiple springs 108, it is possible to accommodate locations where the amount of pipe movement is large. 【0034】 In the modified example described above, the support frame 110 restricts the movement of the spring 108 in the xy plane, and without using a cover to enclose the sides of the spring 108, it is possible to effectively prevent the spring 108 from falling off or buckling while allowing it to slide in the z direction. This contributes to reducing the weight of the pipe support device, lowering manufacturing costs, and reducing the burden of maintenance work. 【0035】 <Second Embodiment> In this embodiment, a pipe support device 160 having a different structure from the pipe support device 100 described in the first embodiment will be described. Configurations identical or similar to those described in the first embodiment may be omitted from the description. 【0036】 A schematic perspective view of the pipe support device 160 is shown in Figure 12, and side views are shown in Figures 13 and 14. As shown in these figures, the pipe support device 160 comprises, as a basic configuration, 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 pipe support device 160 may further optionally have a first band plate 140 and a second band plate 144. 【0037】 1. Hanger plate Schematic top views of the pipe support device 160 are shown in Figures 15(A) and 15(B). In Figure 15(B), the hanger plate 102 is shown with a dashed line for clarity. The hanger plate 102 is a component for suspending the pipe 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 suspension 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 arbitrarily determined. As shown in Figure 15(B), the shape of the hanger plate 102 in the xy plane may be a cross shape, or, although not shown, a polygon including a square or rectangle. 【0038】 2. Base plate Schematic top and bottom views of the pipe support device 160 are shown in Figures 16(A) and 16(B), respectively. For ease of viewing, the hanger plate 102 and spring seat 106 are not shown in Figure 16(A). The base plate 146 is a part that has the function of supporting the spring 108, and as shown in Figures 16(A) and 16(B), it has a through hole 146a through which the turnbuckle 116 can pass, and its top surface is configured to overlap the spring 108. As shown in Figure 16(B), the base plate 146 may also have a cross shape, but its shape is arbitrary as long as the above function can be achieved, and it may be a polygon including a square or rectangle, a circle or an ellipse. 【0039】 3. Spring constellation The spring seat 106 is located between the spring 108 and the hanger plate 102, and at least a portion of it overlaps with the hanger plate 102. The configuration of the spring seat 106 of the pipe support device 160 is the same as that of the spring seat 106 of the pipe support device 100 described in the first embodiment, so a detailed explanation is omitted. 【0040】 4. Support frame The multiple support frames 142 extending in the z direction have the function of suppressing the movement of the spring 108 in the xy plane and preventing buckling. There is no restriction on the number of support frames 110, but for example, as shown in Figures 12 to 15(B), the multiple support frames 142 can include the first to fourth support frames 142-1 to 142-4. The following explanation will continue using an example in which the multiple support frames 142 include the first to fourth support frames 142-1 to 142-4. 【0041】 In the examples shown in these figures, the length of each support frame 142 (length in the z-direction) is longer than the distance between the base plate 146 and the hanger plate 102. Therefore, multiple support frames 142 surround the base plate 146 and the hanger plate 102, with the upper and lower ends of each support frame 142 located 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, multiple support frames 142 can 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 pipe support device 100, the support frame 142 of the pipe support device 160 is also arranged 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 surround the central part 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 central part 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 central part 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. In addition, the central part 106a is sandwiched between two arbitrarily selected support frames 142 (see Figure 15(B)). Note that in Figure 15(B), the support frames 142 do not contact the spring seat 106, but the support frames 142 and the spring seat 106 may be configured such that at least one of the support frames 142 contacts the spring seat 106. 【0043】 Here, as shown in Figure 16(A), the support frames 142 are arranged such that the distance d3 in the xy-plane between two adjacent support frames 142 in the x-direction or y-direction is smaller than the outer diameter D of the spring 108. The distance d3 in the x-direction between two adjacent support frames 142 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 d3 in the y-direction between two adjacent support frames 142 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) may be the same or different. By adopting such an arrangement, the spring 108 cannot pass between adjacent support frames 142, and as a result, the spring 108 can be prevented from falling off the pipe support device 160. 【0044】 The shape of the support frame 142 (shape in the xy plane) can also be arbitrarily determined. For example, it may be an L-shape as shown in Figures 15(A) to 16(B), or it may be a circle, ellipse, or square, although these are not shown. In the case of an L-shape, it is preferable that the support frame 142 is made of angle steel and positioned so that its inner side (acute angle side) faces the spring 108. By positioning the L-shaped support frame 142 in this way, the gap d3 can be made smaller, so the movement of the spring 108 in the xy plane can be suppressed more effectively. 【0045】 4. Springs and turnbuckles Since the spring 108 and turnbuckle 116 can have the same configuration as the spring 108 and turnbuckle 116 of the pipe support device described in the first embodiment, a detailed explanation will be omitted. In the example shown in Figure 12, at least one spring 108 includes multiple springs 108, and adjacent springs 108 overlap each other vertically via the intermediate ring 109. However, there is no restriction on the number of springs 108; there may be one or three or more. 【0046】 5. Other components The first band plate 140 is positioned on top of the second band plate 144 and is fixed to a plurality of support frames 142 by welding or bolting. As shown in Figures 12 to 14, the first band plate 140 can be positioned on the hanger plate 102, in which case an opening is provided for the suspension ring 138 to be exposed. If the upper end of the support frame 142 is positioned above the hanger plate 102, the support frame 142 passes through this opening. The first band plate 140 may also be positioned below the hanger plate 102. Furthermore, the first band plate 140 and the hanger plate 102 may be in contact with each other or separated from each other. 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 positioned below the first band plate 140 and is secured to the support frame 142 by welding or bolting. As shown in Figures 12 to 14, the second band plate 144 can be positioned on top of the base plate 146, or it may be positioned below the base plate 146. The second band plate 144 and the base plate 146 may be in contact with each other or separated from each other. In the former case, the second band plate 144 and the base plate 146 are secured 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 support frame 142 can be more securely fixed to the hanger plate 102 and the base plate 146 by providing the first band plate 140 and the second band plate 144. 【0049】 In the pipe support device 160 having the above configuration, the end 106b of the spring seat is sandwiched between the adjacent support frame 142. Therefore, the support frame 142 acts as a guide, and the spring seat 106 can slide up and down along the support frame 142 as the spring 108 expands and contracts. In addition, a pair of guide rods 112 may also be formed in the pipe support device 100, similar to the pipe support device 100. In this case, as shown in Figure 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 pipe support device 100, so a detailed explanation is omitted. 【0050】 Furthermore, similar to the pipe support device 100, a pair of fixing plates 114 sandwiching multiple support frames 142 may be provided to pre-set the spring 108 (Figure 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. If a first band plate 140 is provided, the opening through which the hanger plate 102 passes should be configured to also pass through the first band plate 140 at the same time. 【0051】 In the pipe support device 160, the turnbuckle 116 and spring seat 106 vibrate vertically due to changes in the mass of the fluid being transported in the pipe 152, causing the spring 108 to expand and contract. As a result, a rotational force is also applied to the spring 108 around its spring axis, which can cause the spring 108 to move in the xy plane. Furthermore, buckling may occur when the spring 108 expands and contracts. However, as described above, the pipe support device 160 is provided with a support frame 142 to prevent the spring 108 from falling out, thus effectively preventing the spring 108 from falling out. In addition, the support frame 142 suppresses deformation of the spring 108 other than expansion and contraction, thus effectively preventing buckling. 【0052】 Similar to the pipe support device 100, the pipe support device 160 can effectively prevent the spring 108 from falling off or buckling without the need for a cover to enclose the side of the spring 108. This contributes to reducing the weight of the pipe support device, lowering manufacturing costs, and reducing the burden of maintenance work. 【0053】 The embodiments described above as examples of the present invention can be combined and implemented as appropriate, insofar as they do not contradict each other. Furthermore, any additions, deletions, or design modifications made by those skilled in the art based on these embodiments are also included within the scope of the present invention, as long as they retain the essence of the present invention. 【0054】 Furthermore, any effects or benefits other than those brought about by the embodiments described above, if they are clear from the description herein or easily predictable to those skilled in the art, are naturally understood to be brought about by the present invention.
