Description

[Technical Field]

[0001] One embodiment of the present invention relates to a support structure. [Background technology]

[0002] To transport fluids, devices such as pipes, valves that control the fluid, and containers that store the fluid are used. When a fluid flows inside a device such as a pipe, valve, or container, the weight or temperature of the device changes. As a result, the position of the device changes from the position where the device was initially placed. A support structure generates a certain reaction force against this movement and follows it.

[0003] For example, Patent Document 1 discloses a vibration control device (support structure) for piping that supports the piping from the fixed side, in which the piping and the fixed side are connected by a cylinder and a piston rod that moves inside the cylinder, and the amount of movement of the cylinder and the piston rod is restricted using a superplastic coil member and an elastic coil spring so that when one side undergoes compressive deformation, the other side undergoes tensile deformation.Furthermore, for example, Patent Document 2 discloses a hanging support structure (support structure) for seismic isolation piping, in which a connecting pipe arranged between the building side piping and the ground side piping is suspended from the bottom of the building via a wire and spring mechanism.

[0009] Hereinafter, each embodiment of the support structure of the present invention will be described with reference to the drawings, with an example using piping as the equipment. However, the present invention can be embodied in various forms without departing from the spirit of the present invention, and should not be interpreted as being limited to the description of the embodiments exemplified below. For example, the support structure may use a valve or a container as the equipment.

[0010] 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 with reference to the previous drawings may be assigned the same reference numerals, and duplicate explanations may be omitted.

Furthermore, from "front" to "rear", the right side is "right" and the left side is "left".

[0015] First Embodiment 1-1. Configuration of the support structure 10

[0016] The configuration of the support structure 10 will be described with reference to Figures 1 to 5. Figure 1 is a perspective view showing the configuration of the support structure 10, Figure 2 is a plan view showing the support structure 10 as seen from the front, Figure 3 is a plan view showing the support structure 10 as seen from the rear, and Figure 4 is a cross-sectional view showing the cut surface of the support structure 10 along D1-D2 shown in Figures 2 and 3. Figure 5 is a plan view showing an outline of the operation of the support structure 10, and is a plan view showing the support structure 10 as seen from the front. The state of the support structure 10 shown in Figure 5 is a state in which the load of the piping 171 is applied.

[0017] The support structure 10 supports the piping as equipment and has the function of following the movement of the piping due to changes in heat or weight. The support structure 10 includes a support mechanism 100, a rotation mechanism 130, and a torsion bar 150 that connects the support mechanism 100 and the rotation mechanism 130. The support structure 10 may also include a shaft portion 172 and a turnbuckle 173. The support structure 10 is mainly formed using metal such as iron or stainless steel.

[0018] 1-1-1.Support mechanism 100 The support mechanism 100 has a function of fixing the support structure 10 to a building or a support pillar of a plant or the like on which the support structure 10 is installed, and a function of suspending the piping 171. The support mechanism 100 also has a function of rotatably supporting the rotation mechanism 130. The support mechanism 100 includes a support portion 110 and a bearing 120.

[0019] The support portion 110 includes a support plate 112 having a first end 110U and a second end 110D. For example, the support plate 112 has a shape that is symmetrical with respect to the first central axis 105, and the width of the support plate 112 in the left-right direction narrows from the first end 110U toward the second end 110D.

[0020] The first end 110U includes an opening 110HL and an opening 110HR for fixing the support structure 10 to a post or the like. The second end 110D includes an opening 110H for mounting the bearing 120.

[0021] The aperture 110HL is provided at a position symmetrical to the aperture 110HR in the support plate 112, with the first central axis 105 as the axis of symmetry. A line connecting the center 111 of the aperture 110HL and the center of the aperture 110HR perpendicularly intersects with the first central axis 105. The length of the perpendicular line connecting the center 111 of the aperture 110HL and the first central axis 105 and the length of the perpendicular line connecting the center 111 of the aperture 110HR and the first central axis 105 are length L2.

[0022] The method for fixing the support structure 10 to a support or the like is arbitrary. For example, the support structure 10 may be fixed to a building or a support or the like by using mounting members so that the openings 110HL and 110HR are fixed to the building or a support or the like. Alternatively, the support structure 10 may be fixed to a support or the like by inserting pin-shaped members into the openings 110HL and 110HR.

[0023] By fixing the support structure 10 to a building, a support pillar, etc. at two points using the two mutually symmetrical openings 110HL and 110HR, the support structure 10 is fixed to the building, a support pillar, etc. more stably than when the support structure 10 is fixed to the building, a support pillar, etc. using one opening. As a result, the support structure 10 is more likely to generate a constant reaction force and follow changes in the position where the piping 171 is initially placed than when the support structure 10 is fixed to the building, a support pillar, etc. using one opening.

[0024] The bearing 120 includes a pipe 124 having a first end 124F and a second end 124B. The bearing 120 (pipe 124) is inserted through the opening 110H and fixed to the support part 110. More specifically, the first end 124F is rotatably inserted through the rotation mechanism 130 (pipe 154), and the second end 124B is exposed from the rotation mechanism 130 (pipe 154) and fixed to the support part 110 at the opening 110H. The pipe 124 includes an opening 124H corresponding to the inner diameter of the pipe 124, a pair of openings 152H, a pair of openings 153H, and an opening 150BH. The torsion bar 150 is inserted through the pipe 124 so that a second central axis 155, which is the axial center of the torsion bar 150, passes through the center of the opening 110H. The length of the bearing 120 (pipe 124) exposed from the rotation mechanism 130 (pipe 154) in the front-rear direction is shorter than the length of the pipe 154 in the front-rear direction.

[0025] The method for fixing the bearing 120 to the second end 110D is arbitrary. For example, the bearing 120 may be fixed by welding to the second end 110D using a welding material, or may be fixed to the second end 110D using solder.

[0026] 1-1-2. Rotation mechanism 130 The rotation mechanism 130 receives the load of the pipe 171 and has a function of stabilizing the position of the support structure 10 by deforming the torsion bar 150 in the rotation mechanism 130 in response to the load. The rotation mechanism 130 includes a pipe 154 and an arm portion 140.

[0027] The pipe 154 is disposed forward with respect to the first central axis 105 and includes an opening 154H corresponding to the inner diameter of the pipe 154, a first end 154F, and a second end 154B. A pair of openings 152H formed on the left and right, a pair of openings 153H formed on the left and right, and an opening 150FH are provided on the first end 154F side. The opening 154H, the pair of openings 152H, the pair of openings 153H, and the opening 150FH are provided at different positions on the pipe 154. The torsion bar 150 passes through the pipe 154 such that a second central axis 155, which is the axial center of the torsion bar 150, passes through the center of the opening 154H. A bearing 120 is inserted into the pipe 154 on the second end 154B side. At this time, first end 124F of bearing 120 (pipe 124) is inserted between first end 154F and second end 154B of pipe 154, and first end 124F overlaps pipe 154. Second end 154B side of pipe 154 is inserted through opening 140FH of arm portion 140 (first arm portion 140F) and fixed (attached) to arm portion 140 (first arm portion 140F) at opening 140FH.

[0028] The pipe 154 can be fixed to the arm portion 140 in the same manner as the method for fixing the bearing 120 to the second end portion 110D.

[0029] The arm portion 140 rotates together with the pipe 154 relative to the pipe 124 of the bearing 120 in response to the load of the piping 171. The arm portion 140 also has the function of moving away from the support portion 110 and reversibly moving up and down in response to the load of the piping 171, thereby stabilizing the position of the piping 171. The arm portion 140 includes a first arm portion 140F and a second arm portion 140S disposed on the right side of the support structure 10.

[0030] The first arm portion 140F includes an opening 140FH. The pipe 154 is inserted through the opening 140FH and fixed (attached) to the opening 140FH.

[0031] The second arm portion 140S includes an aperture 140SH. The second arm portion 140S extends on the side opposite to the side on which the aperture 140FH of the first arm portion 140F is provided, and is provided so as to bend from the aperture 140FH towards the aperture 140SH.

[0032] 1 includes a first arm portion 140F extending to the left of the first central axis 105 and a second arm portion 140S provided on the left side of the first central axis 105, with the first central axis 105 being a left-right symmetrical axis when the support structure 10 is viewed from the front to the rear. The configuration of the arm portion 140 is not limited to the configuration shown in Fig. 1, and may include a first arm portion 140F extending to the right of the first central axis 105 and a second arm portion 140S provided on the right side of the first central axis 105, with the first central axis 105 being a left-right symmetrical axis.

[0033] A support structure 10 according to one embodiment of the present invention includes one arm portion 140 provided on either the left or right side (the left side in FIG. 1 ). When the support structure 10 is viewed from the front, the opening 140SH to which the pipe 171 is attached and the openings 110HL and 110HR for supporting the support structure 10 are set at approximately the same position in the vertical direction and are provided above the centers of the openings 110HL and 110HR and the second central axis 155. As a result, for example, when the pipe 171 is attached to the arm portion 140 and the arm portion 140 receives the load of the pipe 171, the angle α1 by which the arm portion 140 rotates is larger than in a configuration in which the arm portions are provided on both the left and right sides. This increases the stroke amount due to the force received by the support structure 10 due to the load. Furthermore, for example, when the pipe 171 is attached to the arm portion 140, the force that the support structure 10 receives due to the load of the pipe 171 is set higher than in a configuration in which the arm portions are provided on both the left and right sides. Therefore, the support structure 10 can support the pipe 171 that is arranged in a narrow area.

[0034] 1-1-3.Torsion bar 150 The torsion bar 150 includes bent portions 150FE and 150BE. As described in "1-1-1" and "1-1-2," the torsion bar 150 is inserted into the bearing 120 so that the second central axis 155, which is the axial center of the torsion bar 150, passes through the center of the opening 110H. The front of the torsion bar 150 is held between the attachment member 152 inserted into the pair of openings 152H and the attachment member 153 inserted into the pair of openings 153H, and the end of the torsion bar 150 on the bent portion 150FE side is inserted into the opening 150FH. The rear of the torsion bar 150 is held between the attachment member 122 inserted into the pair of openings 122H and the attachment member 123 inserted into the pair of openings 123H, and the end of the torsion bar 150 on the bent portion 150BE side is inserted into the opening 150BH. Torsion bar 150 is attached to pipe 154 and pipe 124 as described above.

[0035] The rotation mechanism 130 (pipe 154) and the torsion bar 150 on the side connected to the rotation mechanism 130 (pipe 154) can rotate together around the second central axis 155, which serves as the rotation axis. On the other hand, the torsion bar 150 on the side connected to the bearing 120 (pipe 124) is fixed to the pipe 124 (bearing 120) and is restricted from rotating. When the rotation mechanism 130 rotates around the second central axis 155, which serves as the rotation axis, the torsion bar 150 on the side connected to the rotation mechanism 130 rotates together with the rotation mechanism 130, and the rotation of the torsion bar 150 on the side connected to the bearing 120 is restricted. As a result, the torsion bar 150 becomes twisted in the rotation direction from the bent portion 150BE side attached to the pipe 124 toward the bent portion 150FE side attached to the pipe 154.

[0036] The support structure 10 includes a configuration in which it is fixed to a building or a pillar by a support mechanism 100, a configuration in which the rotation mechanism 130 (pipe 154) is rotatably attached to the support mechanism 100 (pipe 124 of the bearing 120), a configuration in which the torsion bar 150 is attached to the rotation mechanism 130 (pipe 154) and the support mechanism 100 (pipe 124 of the bearing 120), a configuration in which the second central axis 155, which is the axial center of the torsion bar 150, passes through the center of the opening 110H, a configuration in which the rotation mechanism 130 (arm portion 140) and the torsion bar 150 work together in response to the load on the piping 171, rotating relative to the support mechanism 100 (bearing 120) and causing the arm portion 140 to move downward, and a configuration in which the torsion bar 150 becomes twisted in response to the load on the piping 171.

[0037] As a result, the support structure 10 can distribute and absorb the load of the pipes 171. Therefore, the support structure 10 can stably support the pipes 171 with various loads.

[0038] 1-1-4. Shaft portion 172, turnbuckle 173, and piping fixture 170 The shaft portion 172 has a function of connecting the turnbuckle 173 to the rotation mechanism 130. The shaft portion 172 includes a shaft and an attachment portion to which the shaft is attached. The attachment portion included in the shaft portion 172 is attached to the opening 140SH of the arm portion 140 of the rotation mechanism 130.

[0039] The turnbuckle 173 has a function of connecting the support structure 10 to the piping 171. A shaft portion 172 is connected to the turnbuckle 173. The turnbuckle 173 is disposed between and connected to the shaft portion 172 and a piping fixture 170 that fixes the piping 171. When fixing (installing) the piping 171, the turnbuckle 173 can be moved up and down relative to the shaft portion 172, which includes a screw thread, by rotating the turnbuckle 173. As a result, the turnbuckle 173 can adjust the positions of the support structure 10 and the piping 171.

[0040] 1-2. Example of Operation of Support Structure 10 An example of the operation of the support structure 10 will be described with reference to Figures 5 and 6. Figure 6 is a plan view showing an outline of the operation of the support structure 10, and is a plan view showing the support structure 10 as seen from behind. The state of the support structure 10 shown in Figure 6 is a state in which the load of the piping 171 is applied. In Figures 5 and 6, some of the reference numerals and dashed lines shown in Figures 1 to 4 have been omitted to make the drawings easier to understand. Configurations that are the same as or similar to those in Figures 1 to 5 will be described as necessary.

[0041] 1 to 4 are diagrams showing the state of the support structure 10 before the piping 171 is fixed (installed or connected). For example, the state of the support structure 10 shown in FIGS. 1 to 4 is the initial state. The width L1 in the left-right direction of the support structure 10 is the length from the end of the second arm portion 140S to the right end of the support plate 112, and is the minimum width of the support structure 10 in the left-right direction.

[0042] 2 and 5 (FIGS. 3 and 6), when the support structure 10 is subjected to the load of the piping 171 from the initial state, the support structure 10 strokes downward (in the direction indicated by the thick black straight arrow) due to the force applied downward to the support structure 10 via the piping fixture 170, the turnbuckle 173, and the shaft portion 172. In other words, as the load of the piping 171 occurs, the arm portion 140 of the rotation mechanism 130 moves from the position indicated by the dashed line in FIG. 5 and FIG. 6 to the position indicated by the solid line.

[0043] 2 and 5, the rotation mechanism 130 (pipe 124 and arm portion 140) rotates counterclockwise as viewed from the front by an angle α1, with the center of second central axis 155 as a fulcrum. Here, for example, the counterclockwise direction as viewed from the front is the direction indicated by the black arc-shaped arrow whose radius is the line connecting the center of second central axis 155 and center 141 of opening 140SH. For example, the line connecting the center of second central axis 155 and center 141 of opening 140SH is third central axis 145.

[0044] At this time, the bent portion 150FE side (front side) of the torsion bar 150 attached to the pipe 154 rotates counterclockwise around the center of the second central axis 155 as a fulcrum by an angle α1 as viewed from the front. In addition, the second end side (rear side) of the torsion bar 150 attached to the pipe 124 is fixed to the pipe 124 so that rotation is suppressed. That is, as the torsion bar 150 moves from the second end side toward the bent portion 150FE side, it receives a force that rotates counterclockwise about the second central axis 155, which is the axial center, and becomes twisted so as to balance the load of the piping, and a reaction force of the piping load is generated in the support structure 10. As a result, the length from the end of the second arm portion 140S to the right end of the support plate 112 increases, and the width L1 (minimum width in the left-right direction) in the initial state expands to a width L2.

[0045] As shown in Figures 3 and 6, when the support structure 10 is viewed from behind, the rotation mechanism 130 (pipe 124 and arm portion 140) rotates in the opposite direction to when viewed from the front, i.e., clockwise at an angle α1 with the center of the second central axis 155 as the fulcrum.

[0046] Conventional support structures have relatively complicated structures such as moving mechanisms or spring mechanisms. On the other hand, the support structure 10 includes three components, namely, the support mechanism 100, the rotation mechanism 130, and the torsion bar 150, and can provide a support structure with a relatively simple configuration. The support structure 10 can stabilize the position of the pipe 171 with a relatively simple configuration using the torsion bar 150.

[0047] Furthermore, for example, the support structure 10 has a simpler configuration than conventional support structures, and therefore expansion of the device in the left-right or up-down directions is suppressed, making it small and lightweight. As a result, the support structure 10 can support equipment installed in a variety of areas, from narrow to wide.

[0048] Also, for example, the support structure 10 has a simpler configuration than conventional support structures. As a result, the number of components constituting the support structure 10 is small, which makes the support mechanism 100, the rotation mechanism 130, and the torsion bar 150 highly visible from the outside, and facilitates maintenance of the support structure 10, including replacement of the torsion bar 150. Furthermore, because the number of components constituting the support structure 10 is small, friction between the components in response to the load of the supported piping and the like can be reduced (suppressed). Furthermore, by reducing friction, the support structure 10 can suppress hysteresis during forward and backward movement due to the load of the supported piping and the like, thereby suppressing deterioration of the support structure 10. Therefore, the support structure 10 can provide a support structure with high long-term reliability.

[0049] 1-3. Examples of torsion bar shapes An example of a torsion bar used in the support structure 10 will be described with reference to Fig. 7. Fig. 7 is a plan view showing an example of the shape of the torsion bar. Configurations that are the same as or similar to those in Figs. 1 to 6 will be described as necessary.

[0050] The torsion bar 160 has a cylindrical shape as shown in the cross section A1-A2 of the torsion bar 160 taken along A1-A2. The torsion bar 160 includes a first end 160FE and a second end 160BE. An opening 160FH is provided in the first end 160FE, and an opening 160BH is provided in the second end 160BE. For example, the torsion bar 160 is fixed to the opening 153H or opening 152H of the pipe 154 and the opening 123H or opening 122H of the pipe 124 by inserting mounting members such as pins or bolts through the openings 160FH and 160BH.

[0051] As shown in the cross section A1-A2 of the torsion bar 161 taken along A1-A2, the torsion bar 161 has a rectangular prism shape. The torsion bar 161 includes a first end 161FE and a second end 161BE. An opening 161FH is provided in the first end 161FE, and an opening 161BH is provided in the second end 161BE. For example, like the torsion bar 160, the torsion bar 161 is fixed to the opening 153H or the opening 152H of the pipe 154 and the opening 123H or the opening 122H of the pipe 124.

[0052] The torsion bar 162 has a flat plate-like shape as shown in the cross section A1-A2 of the torsion bar 162 taken along A1-A2. The torsion bar 162 includes a first end 162FE and a second end 162BE. An opening 162FH is provided in the first end 162FE, and an opening 162BH is provided in the second end 162BE. For example, like the torsion bar 160, the torsion bar 162 is fixed to the opening 153H or the opening 152H of the pipe 154 and the opening 123H or the opening 122H of the pipe 124.

[0053] As shown in the cross section A1-A2 of the torsion bar 163, the torsion bar 163 has an octagonal prism shape. The torsion bar 163 includes a first end 163FE and a second end 163BE. An opening 163FH is provided in the first end 163FE, and an opening 163BH is provided in the second end 163BE. For example, like the torsion bar 160, the torsion bar 163 is fixed to the opening 153H or the opening 152H of the pipe 154 and the opening 123H or the opening 122H of the pipe 124.

[0054] As shown in the cross section A1-A2 of the torsion bar 164, the torsion bar 164 has a sawtooth or gear-like shape. The torsion bar 164 includes a first end 164FE and a second end 164BE. An opening 164FH is provided in the first end 164FE, and an opening 164BH is provided in the second end 164BE. For example, the torsion bar 164, like the torsion bar 160, is fixed to the opening 153H or opening 152H of the pipe 154 and the opening 123H or opening 122H of the pipe 124.

[0055] The torsion bar 150 is the torsion bar shown in Figs. 1 to 6. The shape of the torsion bar 150 is a bent cylinder including two bent portions 150FE and 150BE. As shown in the cross section A1-A2 of the torsion bar 150 taken along A1-A2, the cross section of the torsion bar 150 is circular. The shape of the torsion bar 150 is not limited to the shapes shown in Figs. 1 to 7, and may be, for example, the shapes shown by torsion bars 161 to 164.

[0056] The shape of the torsion bar is not limited to the shape shown in FIG. 7, and may be selected appropriately depending on the application or specifications of the support structure 10, etc.

[0057] Second Embodiment 2-1. Configuration of the support structure 20

[0058] The configuration of the support structure 20 will be described with reference to Figures 8 to 11. Figure 8 is a perspective view showing the configuration of the support structure 20, Figure 9 is a plan view showing the support structure 20 as seen from the front, Figure 10 is a plan view showing the support structure 20 as seen from the rear, and Figure 11 is a cross-sectional view showing the cut surface of the support structure 20 taken along D1-D2 shown in Figures 2 and 3. For example, the state of the support structure 20 shown in Figures 8 to 11 is the initial state. Configurations that are the same as or similar to those in Figures 1 to 7 will be described as necessary.

[0059] Like the support structure 10, the support structure 20 supports piping as equipment and has the function of following the movement of the piping due to changes in heat and weight. The support structure 20 includes a support mechanism 200, a rotation mechanism 230, and a torsion bar 250 that connects the support mechanism 200 and the rotation mechanism 230. The support structure 20 differs from the support structure 10 in the configuration related to the torsion bar. Specifically, the torsion bar 150 of the support structure 10 is attached to the pipes 254 and 224 using mounting members, whereas the torsion bar 250 of the support structure 20 is attached to the pipes 254 and 224 using caps 252 and 222, etc. The other configurations and functions of the support structure 20 are similar to those of the support structure 10. Therefore, in describing the configuration and function of the support structure 20, the configuration and function related to the torsion bar 250, which is different from the torsion bar 150 of the support structure 10, will be described, and the configuration and function similar to those of the support structure 10 will be described as necessary.

[0060] 2-1-1. Support mechanism 200 The support mechanism 200 has the same function as the support mechanism 100. Specifically, the support mechanism 200 has a function of fixing the support structure 20 to a building or a support pillar of a plant or the like on which the support structure 20 is installed, and a function of suspending the piping 171. The support mechanism 200 also has a function of rotatably supporting the rotation mechanism 230. The support mechanism 200 includes a support portion 110 and a bearing 220.

[0061] The support portion 110 includes the same configuration as the support portion 110 of the support structure 10 according to the first embodiment, so a description of the support portion 110 will be omitted here.

[0062] The bearing 220 includes a pipe 224 having a first end 224F and a second end 224B, and a cap 222. The bearing 220 (pipe 224) is inserted through the opening 110H and fixed to the support part 110. More specifically, the first end 224F is rotatably inserted through the rotation mechanism 230 (pipe 254), and the second end 224B is exposed from the rotation mechanism 230 (pipe 254) and fixed to the support part 110 at the opening 110H. The length of the bearing 220 (pipe 224) exposed from the rotation mechanism 230 (pipe 254) in the front-rear direction is shorter than the length of the pipe 254 in the front-rear direction.

[0063] Pipe 224 includes an opening 224H that corresponds to the inner diameter of pipe 224. Cap 222 includes an opening 222H.

[0064] In the pipe 224, the torsion bar 250 is inserted into the opening 224H so that the second central axis 155, which is the axial center of the torsion bar 250, passes through the center of the opening 110H. In addition, the torsion bar 250 is inserted into the opening 222H of the cap 222, and the cap 222 with the torsion bar 250 inserted therein is fitted into the first end 250B side of the pipe 224.

[0065] The method for fixing the bearing 220 to the second end 110D can be the same as the method for fixing the bearing 120 to the second end 110D.

[0066] 2-1-2. Rotation mechanism 230 The rotation mechanism 230 has the same function as the rotation mechanism 130. Specifically, the rotation mechanism 230 receives the load of the pipe 171 and has a function of stabilizing the position of the support structure 20 by deforming the torsion bar 250 in the rotation mechanism 230 in response to the load. The rotation mechanism 230 includes a pipe 254 and an arm portion 140.

[0067] The pipe 254 is disposed forward with respect to the first central axis 105, and includes an opening 254H corresponding to the inner diameter of the pipe 254, a first end 254F, and a second end 254B. The torsion bar 250 is passed through the pipe 254 so that the second central axis 155, which is the axial center of the torsion bar 250, passes through the center of the opening 254H. In addition, the bearing 220 is inserted into the second end 254B side of the pipe 254. At this time, the first end 224F of the bearing 220 (pipe 224) is inserted up to between the first end 254F and the second end 254B of the pipe 254, and the first end 224F overlaps the pipe 254. The second end 254B side of the pipe 254 is inserted into the opening 140FH of the arm portion 140 (first arm portion 140F) and is fixed (attached) to the arm portion 140 (first arm portion 140F) at the opening 140FH.

[0068] In the pipe 254, the torsion bar 250 is inserted into the opening 254H so that the second central axis 155, which is the axial center of the torsion bar 250, passes through the center of the opening 110H. In addition, the torsion bar 250 is inserted into the opening 252H of the cap 252, and the cap 252 with the torsion bar 250 inserted therein is fitted into the first end 254F side of the pipe 254.

[0069] The pipe 254 can be fixed to the arm portion 140 in the same manner as the method for fixing the bearing 220 to the second end portion 110D.

[0070] The arm section 140 includes the same configuration as the arm section 140 of the support structure 10 according to the first embodiment, so a description of the arm section 140 will be omitted here.

[0071] 2-1-3.Torsion bar 250 As explained in "2-1-1" and "2-1-2," the torsion bar 250 is inserted into the bearing 220 so that the second central axis 155, which is the axial center of the torsion bar 250, passes through the center of the opening 110H. The front of the torsion bar 250 is inserted into the opening 252H of the cap 252, and the cap 252 with the torsion bar 250 inserted therein is fitted into the first end 254F side of the pipe 254. The rear of the torsion bar 250 is inserted into the opening 222H of the cap 222, and the cap 222 with the torsion bar 250 inserted therein is fitted into the second end 224B side of the pipe 224. The torsion bar 250 is attached to the pipe 254 and the pipe 224 as explained above.

[0072] The rotation mechanism 230 (pipe 254) and the torsion bar 250 on the side connected to the rotation mechanism 230 (pipe 254) can rotate together around the second central axis 155, which serves as the rotation axis. On the other hand, the torsion bar 250 on the side connected to the bearing 220 (pipe 224) is fixed to the pipe 224 (bearing 220) and is restricted from rotating. When the rotation mechanism 230 rotates around the second central axis 155, which serves as the rotation axis, the torsion bar 250 on the side connected to the rotation mechanism 230 rotates together with the rotation mechanism 230, and the rotation of the torsion bar 250 on the side connected to the bearing 220 is restricted. As a result, the torsion bar 250 becomes twisted in the rotation direction from the bending portion 150BE side attached to the pipe 224 toward the bending portion 150FE side attached to the pipe 254.

[0073] The support structure 20 operates in the same manner as the support structure 10. Furthermore, the support structure 20 can achieve the same effects as the support structure 10.

[0074] 2-2. An example of how to install a torsion bar An example of a method for attaching a torsion bar will be described with reference to Figures 12 to 18. Figures 12 to 18 are plan views or cross-sectional views showing an example of a method for attaching a torsion bar. Note that Figures 12 to 18 explain a method for attaching a torsion bar to pipe 254 using cap 253 or the like, but the method for attaching a torsion bar to pipe 224 is similar to the method for attaching a torsion bar to pipe 254. Furthermore, the method for attaching a torsion bar shown in Figures 12 to 18 is just one example, and the method for attaching a torsion bar is not limited to the example shown in Figures 12 to 18. Configurations that are the same as or similar to those in Figures 1 to 11 will be described as necessary.

[0075] 12 , the cap 252, with the front of the torsion bar 250 attached to the opening 252H, may be fitted onto the pipe 254, and then the welding material 256 may be welded to the cap 252 and the pipe 254. The welding material 256 may be welded to the cap 252 and the torsion bar 250. Alternatively, the cap 222, with the rear of the torsion bar 250 attached to the opening 222H, may be fitted onto the pipe 224, and then the welding material 256 may be welded to the cap 222 and the pipe 224. The welding material 256 may be welded to the cap 222 and the torsion bar 250. By providing the welding material 256 to the cap 252 and the cap 222, the cap 252 is firmly fixed to the pipe 254, and the cap 222 is firmly fixed to the pipe 224. As a result, the cap 252, the cap 222, and the torsion bar 250 can be prevented from falling off the pipe 254 and the pipe 224.

[0076] As shown in FIG. 13 , the pipe 254 may include a plurality of notches 257. For example, the pipe 254 includes four notches 257. The cap 252 has protrusions 258 at positions corresponding to the notches 257 of the pipe 254. The front of the torsion bar 250 is attached to the opening 252H and fitted onto the pipe 254 so that the protrusions 258 of the cap 252 fit into the notches 257 of the pipe 254. Also, the pipe 224 may include a plurality of notches 227. For example, the pipe 224 includes four notches 227. The cap 222 has protrusions 228 at positions corresponding to the notches 227 of the pipe 224. The rear of the torsion bar 250 is attached to the opening 222H and fitted onto the pipe 224 so that the protrusions 228 of the cap 222 fit into the notches 227 of the pipe 224. 12 , after the cap 252 is fitted onto the pipe 254, the welding material 256 may be welded to the cap 252 and the pipe 254, or the welding material 256 may be welded to the cap 252 and the torsion bar 250. Also, like the configuration shown in Fig. 12 , after the cap 222 is fitted onto the pipe 224, the welding material 256 may be welded to the cap 222 and the pipe 224, or the welding material 256 may be welded to the cap 222 and the torsion bar 250. The cap 252 is firmly fixed to the pipe 254 by fitting the protrusion 258 of the cap 252 into the cutout 257 of the pipe 254, and the cap 252 is firmly fixed to the pipe 224 by fitting the protrusion 228 of the cap 222 into the cutout 227 of the pipe 224. As a result, the cap 252, the cap 222, and the torsion bar 250 can be prevented from falling off the pipe 254 and the pipe 224.

[0077] 14 is a cross-sectional view showing the D5-D6 cut surface of the cap 252, the pipe 254, the cap 222, the pipe 224, and the torsion bar 250. Fig. 14 shows an example in which a welding material 256 is welded to the cap 252, the pipe 254, the cap 222, the pipe 224, and the torsion bar 250, thereby fixing the cap 252, the cap 222, the pipe 224, and the torsion bar 250 to the pipe 254. By providing the welding material 256 to the cap 252, the pipe 254, the cap 222, the pipe 224, and the torsion bar 250, the cap 252 and the torsion bar 250 are firmly fixed to the pipe 254, and the cap 222 and the torsion bar 250 are firmly fixed to the pipe 224. As a result, the cap 252, the cap 222, and the torsion bar 250 can be prevented from falling off the pipe 254 and the pipe 224.

[0078] Figure 15 is a cross-sectional view showing the D7-D8 cut surface of cap 252, pipe 254, cap 222, pipe 224, and torsion bar 250. Figure 15 shows an example in which the front of torsion bar 250 is attached so as to protrude from opening 252H of cap 252, and the rear of torsion bar 250 is attached so as to protrude from opening 222H of cap 222. Because torsion bar 250 protrudes in the front-to-rear direction, torsion bar 250 is more unlikely to fall off pipe 254 and pipe 224.

[0079] 16 shows an example in which the front portion of the torsion bar 350 protruding from the opening 252H is clamped between two retaining plates 259 provided on the cap 252, and the torsion bar 350 is fixed to the two retaining plates 259 using mounting members (bolts 260 and nuts 261). The two retaining plates 259 are arranged opposite each other. The front portion of the torsion bar 350 includes an opening 350H, and the two retaining plates 259 also include openings 259H. Bolts 260 are inserted through openings 350H in the front portion of the torsion bar 350 protruding from the cap 252 and through openings 259H of the two retaining plates 259 arranged so as to overlap the openings 350H, and the torsion bar 350 is fixed with nuts 261. 17 shows an example in which the rear portion of the torsion bar 350 protruding from the opening 222H is clamped between two retaining plates 229 provided on the cap 222, and the rear portion of the torsion bar 350 is fixed to the two retaining plates 229 using mounting members (bolts 270 and nuts 271). The method of fixing the rear portion of the torsion bar 350 to the two retaining plates 229 is the same as the method of fixing the front portion of the torsion bar 350 to the two retaining plates 259. By clamping the front portion of the torsion bar 350 between the two retaining plates 259 and clamping the rear portion of the torsion bar 350 between the two retaining plates 229, it is possible to prevent the torsion bar 350 from falling off the pipe 254 and the pipe 224.

[0080] 18 is a cross-sectional view showing the D9-D10 cut surface of the cap 253, the pipe 254, the cap 223, the pipe 224, and the rectangular prism-shaped torsion bar 251. FIG. 18 shows an example in which the front portion of the torsion bar 251 is welded to the cap 253 inside the cap 253, and the rear portion of the torsion bar 251 is welded to the cap 223 inside the cap 223. The caps 253 and 223 do not include any openings. The front portion of the torsion bar 251 is welded to the cap 253 inside the cap 253 using welding material 256, and the cap 253 is fitted into the pipe 254 and attached to the pipe 254. The rear portion of the torsion bar 251 is welded to the cap 223 inside the cap 223 using welding material 256, and attached to the pipe 224. The cap 253 is attached to the pipe 254 so as to face the cap 223, and the cap 223 is attached to the pipe 224 so as to face the cap 253. Therefore, the torsion bar 251 is welded and connected between the caps 253 and 223 using a welding material. As a result, the torsion bar 251 can be prevented from falling off the pipe 254 and the pipe 224.

[0081] In the support structure 20, torsion bars having shapes similar to the torsion bar 150 and the torsion bars 160 to 164 shown in FIG. 7 of the first embodiment may be used.

[0082] Third Embodiment 3-1. Configuration of the support structure 30

[0083] The configuration of the support structure 30 will be described with reference to Figures 19 and 20. Figure 19 is a perspective view showing the configuration of the support structure 30, and Figure 20 is a plan view showing the support structure 30 as seen from behind. For example, the state of the support structure 30 shown in Figures 19 and 20 is the initial state. Configurations that are the same as or similar to those in Figures 1 to 18 will be described as necessary.

[0084] Like the support structures 10 and 20, the support structure 30 supports piping as equipment and has the function of following the movement of the piping due to changes in heat or weight. The support structure 30 includes a support mechanism 300, a rotation mechanism 130, and a torsion bar 150 that connects the support mechanism 300 and the rotation mechanism 130. The support structure 30 differs from the support structure 10 in the configuration related to the support mechanism. Specifically, the bearing 120 of the support mechanism 100 of the support structure 10 includes a pipe 124 / 324 that is circular when viewed from the front or rear or in a cross-sectional view, whereas the bearing 320 of the support mechanism 300 of the support structure 30 includes a pipe 324 that is square when viewed from the front or rear or in a cross-sectional view. The other configurations and functions of the support structure 30 are similar to those of the support structure 10. Therefore, when describing the configuration and functions of the support structure 30, we will describe the configuration and functions related to the support mechanism 300, which is different from the support mechanism 100 of the support structure 10, and will describe the configuration and functions similar to those of the support structure 10 as necessary.

[0085] 3-1-1. Support mechanism 300 The support mechanism 300 has a function of fixing the support structure 30 to a building or a support pillar of a plant or the like on which the support structure 30 is installed, and a function of suspending the piping 171. The support mechanism 300 also has a function of rotatably supporting the rotation mechanism 130. The support mechanism 300 includes a support portion 310 and a bearing 320.

[0086] Support 310 includes support plate 312 having first end 310U and second end 310D. First end 310U includes apertures 310HL and 310HR. Second end 310D includes aperture 310H.

[0087] The support plate 312 including the first end 310U and the second end 310D included in the support part 310, the opening 310HL, the opening 310HR, and the opening 310H each have the same configuration and function as the support plate 112 including the first end 110U and the second end 110D included in the support part 110, the opening 110HL, the opening 110HR, and the opening 110H, respectively. Therefore, a description of the support part 310 will be omitted here.

[0088] The bearing 320 includes a pipe 324 having a first end 324F and a second end 324B. The pipe 324 includes a rectangular opening 324H when viewed from the front or rear or in a cross-sectional view. The pipe 324 also includes a pair of openings 322H, a pair of openings 323H, and an opening 350BH. The pipe 324 has a rectangular shape when viewed from the front or rear or in a cross-sectional view. The bearing 320 (pipe 324) is inserted through the rectangular opening 310H and fixed to the support part 310. More specifically, the first end 324F is rotatably inserted through the rotation mechanism 130 (pipe 154), and the second end 324B is exposed from the rotation mechanism 130 (pipe 154) and fixed to the support part 310 at the opening 310H. 19 and 20 is an example, and the shape of the pipe 324 is not limited to a square shape. The length of the bearing 320 (pipe 324) exposed from the rotation mechanism 130 (pipe 154) in the front-rear direction is shorter than the length of the pipe 154 in the front-rear direction.

[0089] The method for fixing the bearing 320 to the second end 310D can be the same as the method for fixing the bearing 120 to the second end 110D.

[0090] 3-1-2. Rotation mechanism 130 The rotation mechanism 130 has the same configuration and function as the rotation mechanism 130 of the support structure 10. Therefore, a detailed description of the rotation mechanism 130 will be omitted here.

[0091] Bearing 320 is inserted into second end 154B of pipe 154. At this time, first end 324F of bearing 320 (pipe 324) is inserted between first end 154F and second end 154B of pipe 154, and first end 324F overlaps pipe 154. Arm 140 rotates together with pipe 154 relative to pipe 324 of bearing 320 in accordance with the load of piping 171.

[0092] 3-1-3.Torsion bar 150 The torsion bar 150 includes bent portions 150FE and 150BE. The torsion bar 150 is inserted through the pipe 154 and the bearing 320 (pipe 324) so ​​that the second central axis 155, which is the axial center of the torsion bar 150, passes through the center of the opening 310H. The front of the torsion bar 150 is held between the attachment member 152 inserted through the pair of openings 152H and the attachment member 153 inserted through the pair of openings 153H, and the end of the torsion bar 150 on the bent portion 150FE side is inserted through the opening 150FH. The rear of the torsion bar 150 is held between the attachment member 322 inserted through the pair of openings 322H and the attachment member 323 inserted through the pair of openings 323H, and the end of the torsion bar 150 on the bent portion 150BE side is inserted through the opening 350BH. Torsion bar 150 is attached to pipe 154 and pipe 324 as described above.

[0093] The rotation mechanism 130 (pipe 154) and the torsion bar 150 on the side connected to the rotation mechanism 130 (pipe 154) can rotate together around the second central axis 155, which serves as the rotation axis. On the other hand, the torsion bar 150 on the side connected to the bearing 320 (pipe 324) is fixed to the pipe 324 (bearing 320) and is restricted from rotating. When the rotation mechanism 130 rotates around the second central axis 155, which serves as the rotation axis, the torsion bar 150 on the side connected to the rotation mechanism 130 rotates together with the rotation mechanism 130, and the torsion bar 150 on the side connected to the bearing 320 is restricted from rotating. As a result, the torsion bar 150 becomes twisted in the rotation direction from the bending portion 150BE side attached to the pipe 324 toward the bending portion 150FE side attached to the pipe 154.

[0094] The support structure 30 operates in the same manner as the support structure 10. Furthermore, the support structure 30 can achieve the same effects as the support structure 10.

[0095] The support structure 30 may use torsion bars having the same shape as the torsion bars 160 to 164 of the first embodiment shown in Fig. 7. The support structure 30 may also be configured using a torsion bar mounting method similar to the torsion bar mounting method shown in Figs. 12 to 18 of the second embodiment.

[0096] <Fourth embodiment> 4-1. Configuration of the support structure 40

[0097] The configuration of the support structure 40 will be described with reference to Figures 21 and 22. Figure 21 is a perspective view showing the configuration of the support structure 40, and Figure 22 is a plan view showing the support structure 40 as viewed from the front. For example, the state of the support structure 40 shown in Figures 21 and 22 is the initial state. Configurations that are the same as or similar to those in Figures 1 to 20 will be described as necessary.

[0098] Like the support structures 10 to 30, the support structure 40 supports piping as equipment and has the function of following the movement of the piping due to changes in heat or weight. The support structure 40 includes a support mechanism 100, a rotation mechanism 430, and a torsion bar 150 that connects the support mechanism 100 and the rotation mechanism 430. The support structure 40 differs from the support structure 10 in the configuration related to the rotation mechanism. Specifically, when viewed from the front or rear or in a cross-sectional view, the rotation mechanism 130 of the support structure 10 includes a circular pipe 154, while the rotation mechanism 430 of the support structure 40 includes a square pipe 454. The other configurations and functions of the support structure 40 are similar to those of the support structure 10. Therefore, in describing the configuration and functions of the support structure 40, the configurations and functions related to the rotation mechanism 430 that are different from the rotation mechanism 130 of the support structure 10 will be described, and the configurations and functions similar to those of the support structure 10 will be described as necessary.

[0099] 4-1-1. Support mechanism 100 The support mechanism 100 has the same configuration and function as the support mechanism 100 of the support structure 10. Therefore, a detailed description of the support mechanism 100 will be omitted here.

[0100] Bearing 120 includes pipe 124 having first end 124F and second end 124B. First end 124F is rotatably inserted into rotation mechanism 430 (pipe 454), and second end 124B is exposed from rotation mechanism 430 (pipe 454) and fixed to support part 110 at opening 110H. The length of bearing 120 (pipe 124) exposed from rotation mechanism 430 (pipe 454) in the front-rear direction is shorter than the length of pipe 454 in the front-rear direction.

[0101] 4-1-2.Rotation mechanism 430 The rotation mechanism 430 has the same function as the rotation mechanism 130. Specifically, the rotation mechanism 430 receives the load of the pipe 171 and has a function of stabilizing the position of the support structure 40 by deforming the torsion bar 150 in the rotation mechanism 430 in response to the load. The rotation mechanism 430 includes a pipe 454 and an arm portion 440.

[0102] The pipe 454 is disposed forward with respect to the first central axis 105 and includes a first end 454F and a second end 454B. The pipe 454 includes a rectangular opening 454H when viewed from the front or rear or in a cross-sectional view. The pipe 454 also includes a pair of openings 452H, a pair of openings 453H, and an opening 450FH. The pipe 454 has a rectangular shape when viewed from the front or rear or in a cross-sectional view. The torsion bar 150 passes through the pipe 454 such that the second central axis 155, which is the axial center of the torsion bar 150, passes through the center of the opening 454H. The bearing 120 is inserted into the second end 454B side of the pipe 454. At this time, first end 124F of bearing 120 (pipe 124) is inserted between first end 454F and second end 454B of pipe 454, and first end 124F overlaps pipe 454. Second end 454B side of pipe 454 is inserted through opening 440FH of arm portion 440 (first arm 440F) and fixed (attached) to arm portion 440 (first arm 440F) at opening 440FH. Note that the shape of pipe 454 shown in Figures 21 and 22 is just an example, and the shape of pipe 454 is not limited to a rectangular shape.

[0103] The pipe 454 can be fixed to the arm portion 440 in the same manner as the method for fixing the bearing 120 to the second end portion 110D.

[0104] The arm portion 440 has the same configuration as the arm portion 440 of the support structure 10 according to the first embodiment. Therefore, a description of the arm portion 440 will be omitted here. The arm portion 440 rotates together with the pipe 454 relative to the pipe 124 of the bearing 120 in accordance with the load of the piping 171.

[0105] 4-2.Torsion bar 150 The torsion bar 150 includes bent portions 150FE and 150BE. The torsion bar 150 is inserted through the pipe 454 and the bearing 120 (pipe 124) so ​​that a second central axis 155, which is the axial center of the torsion bar 150, passes through the center of the opening 110H. The front of the torsion bar 150 is held between an attachment member 452 inserted through a pair of openings 452H and an attachment member 453 inserted through a pair of openings 453H, and the end of the torsion bar 150 on the bent portion 150FE side is inserted through the opening 450FH. The rear of the torsion bar 150 is held between an attachment member 122 inserted through a pair of openings 122H and an attachment member 123 inserted through a pair of openings 123H, and the end of the torsion bar 150 on the bent portion 150BE side is inserted through the opening 150BH. Torsion bar 150 is attached to pipe 454 and pipe 124 as described above.

[0106] The rotation mechanism 430 (pipe 454) and the torsion bar 150 on the side connected to the rotation mechanism 430 (pipe 454) can rotate together around the second central axis 155, which serves as the rotation axis. On the other hand, the torsion bar 150 on the side connected to the bearing 120 (pipe 124) is fixed to the pipe 124 (bearing 120) and is restricted from rotating. When the rotation mechanism 430 rotates around the second central axis 155, which serves as the rotation axis, the torsion bar 150 on the side connected to the rotation mechanism 430 rotates together with the rotation mechanism 430, and the torsion bar 150 on the side connected to the bearing 120 is restricted from rotating. As a result, the torsion bar 150 becomes twisted in the rotation direction from the bending portion 150BE side attached to the pipe 124 toward the bending portion 150FE side attached to the pipe 454.

[0107] The support structure 40 includes a configuration in which it is fixed to a building or a pillar by a support mechanism 100, a configuration in which a rotation mechanism 430 (pipe 454) is rotatably attached to the support mechanism 100 (pipe 124 of the bearing 120), a configuration in which a torsion bar 150 is attached to the rotation mechanism 430 (pipe 454) and the support mechanism 100 (pipe 124 of the bearing 120), a configuration in which a second central axis 155, which is the axial center of the torsion bar 150, passes through the center of the opening 110H, a configuration in which the rotation mechanism 430 (arm portion 440) and the torsion bar 150 work together in response to the load on the piping 171, rotating relative to the support mechanism 100 (bearing 120) and causing the arm portion 440 to move downward, and a configuration in which the torsion bar 150 becomes twisted in response to the load on the piping 171.

[0108] The support structure 40 operates in the same manner as the support structure 10. Furthermore, the support structure 40 can achieve the same effects as the support structure 10.

[0109] The support structure 40 may use torsion bars having the same shape as the torsion bars 160 to 164 of the first embodiment shown in Fig. 7. The support structure 40 may also be configured using a torsion bar mounting method similar to the torsion bar mounting method shown in Figs. 12 to 18 of the second embodiment.

[0110] The support structures and the configurations of the support structures described above as embodiments of the present invention can be combined as appropriate as long as they are not mutually inconsistent. Furthermore, the support structures and the configurations of the support structures described above as embodiments of the present invention can be interchanged as appropriate as long as they are not mutually inconsistent. Furthermore, even if a person skilled in the art adds, deletes, or modifies components as appropriate based on each embodiment, this also falls within the scope of the present invention as long as it maintains the gist of the present invention.

[0111] 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.
