[0006] To achieve the above objective, the structural relocation device according to the present invention is a structural relocation device used when replacing or relocating an existing structural structure, comprising: a traveling section for moving the structural structure in a predetermined direction; a support section for supporting the structural structure; and a height adjustment section interposed between the traveling section and the support section, which is capable of adjusting the height of the support section relative to the traveling section, all integrally configured; and further comprising a direction adjustment section for adjusting the orientation of the structural structure in the horizontal plane.

[0007] This configuration allows existing structures to be easily moved simply by operating the structure moving device. Furthermore, by including a direction adjustment unit, the structure can be moved while maintaining a predetermined orientation in the horizontal plane. In other words, the structure can be efficiently moved in a predetermined orientation without relying on the experience of skilled workers.

[0008] Furthermore, the structural movement device of the present invention may have a rotation mechanism in the orientation adjustment section that allows the structural to rotate in a horizontal plane.

[0009] This configuration allows for easy adjustment of the orientation of the structure within the horizontal plane.

[0010] Furthermore, in the structural movement device of the present invention, the orientation adjustment unit may be provided on the support unit.

[0011] By configuring it in this way, the orientation of the structure within the horizontal plane can be adjusted to a predetermined orientation without installing any separate, large-scale equipment.

[0012] Furthermore, the structural moving device of the present invention may have tires or rollers in the traveling section.

[0013] With this configuration, the running section is equipped with tires or rollers, allowing for reliable guidance of the structure in a predetermined direction (position) during transport. In other words, the structure can be moved efficiently without relying on the experience of skilled workers. The tires or rollers can be made of metal, rubber tires, urethane rollers, etc., and the structure may not have rails.

[0014] Furthermore, the structural movement device of the present invention may be configured such that the traveling section is capable of traveling on a pair of rails provided on both sides of the structural structure.

[0015] With this configuration, the structural movement device is equipped with rails, allowing it to reliably guide the structure in a predetermined direction (position) during transport. In other words, the structure can be moved efficiently without relying on the experience of skilled workers.

[0016] Furthermore, the structural movement device of the present invention may also include, in a plan view, a pair of erection beams extending in a direction perpendicular to the rail and arranged on both sides of the structure, and a pair of support beams spanning the pair of erection beams and capable of supporting the structure.

[0017] By arranging a pair of temporary beams on both sides of the structure to be moved, and supporting the structure between a pair of support beams provided on the temporary beams, the structure can be securely held from both sides.

[0018] Furthermore, the height adjustment unit of the structural movement device of the present invention may be a jack device.

[0019] In this way, by configuring the height adjustment section with a jacking device, the structure can be reliably lifted to a predetermined height.

[0020] The method for moving a structure according to the present invention is a method for moving an existing structure using any of the above-described structure moving devices. A pair of rails are installed on both sides of the structure, the traveling unit is installed on the pair of rails, the support unit is supported and fixed to the structure, and the height adjustment unit is operated to adjust the height of the support unit with respect to the traveling unit, lifting the structure to a predetermined height, operating the orientation adjustment unit to adjust the orientation of the structure in the horizontal plane, and moving the structure to a predetermined position by causing the traveling unit to travel on the pair of rails.

[0021] By configuring it in this way, the existing structure can be easily moved only by operating the structure moving device. In addition, by providing the orientation adjustment unit, the structure can be moved in a state where the orientation in the horizontal plane of the structure is set to a predetermined orientation. That is, the structure can be efficiently moved in a predetermined orientation without relying on the experience of skilled workers.

[0024] Hereinafter, a structural movement device and a structural movement method according to an embodiment of the present invention will be described with reference to Figures 1 to 16. In this embodiment, we will explain how the structural relocation device 1 is used, for example, when relocating a seismic isolation bearing (structure) 10 installed between the pier and deck of a bridge.

[0025] As shown in Figure 1, the seismic isolation bearing 10 is attached to the upper surface 11a of the concrete foundation 11 provided on the upper surface of the bridge pier. The seismic isolation bearing 10 comprises a pair of support plates 12, 12 arranged vertically, and a seismic isolation rubber 13 positioned between the pair of support plates 12, 12. In plan view, the seismic isolation rubber 13 is smaller than the support plates 12. A stepped portion 14 is formed between the support plates 12 and the seismic isolation rubber 13. The stepped portion 14 is formed around the entire circumference of the seismic isolation rubber 13.

[0026] The structural movement device 1 is integrally composed of a traveling unit 2 that moves the seismic isolation bearing 10 in a predetermined direction, a support unit 3 that supports the seismic isolation bearing 10, and a height adjustment unit 5 interposed between the traveling unit 2 and the support unit 3, which can adjust the height of the support unit 3 relative to the traveling unit 2. The traveling unit 2 is configured to travel on rails 6.

[0027] The running unit 2 moves the seismic isolation bearing 10 along the rail 6 in a predetermined direction. The running unit 2 has a plurality of running units 22 equipped with wheels 21, and a connecting unit 23 that connects the running units 22 to each other.

[0028] As shown in Figure 6, the running unit 22 comprises a frame portion 24 made of a long steel material with a substantially U-shaped cross-section, and two wheels 21 positioned at the front and rear axial ends of the frame portion 24. The number of wheels 21 may be three or more depending on the length of the frame portion 24. The running unit 22 is installed along a direction substantially the same as the axial direction of the rail 6. The wheel 21 comprises a wheel body portion 25 that rolls on the upper surface of the rail 6, and a wheel flange portion 26 provided on the inside in the width direction of the wheel body portion 25 so as to abut against the side surface of the rail 6. The wheel flange portion 26 is formed with a larger diameter than the wheel body portion 25.

[0029] The connecting section 23 connects a pair of traveling units 22, 22, which are positioned on both sides in the width direction of the seismic isolation support 10 that is to be moved. By using the connecting section 23 to keep the distance between the pair of traveling units 22, 22 constant, the traveling units 22 can be moved stably without coming off the rail 6 when the seismic isolation support 10 is moved.

[0030] The connection structure between the running unit 22 and the connecting section 23 does not use screws and employs a structure that is substantially the same as the connection structure of the rail 6. This connection structure will be explained in detail later in the section on the connection structure of the rail 6.

[0031] The support section 3 extends in a direction perpendicular to the extension direction of the rail 6 in a plan view and comprises a pair of erection beams 31, 31 arranged on both the front and rear sides in the direction of movement of the seismic isolation bearing 10, and a pair of support beams 32, 32 that span across the pair of erection beams 31, 31 and are capable of supporting the seismic isolation bearing 10 from both sides in the width direction.

[0032] The erection beam 31 is formed, for example, from a steel material with a U-shaped cross-section. The erection beam 31 has a length that spans a pair of traveling units 22, 22, which are arranged on both sides in the width direction of the seismic isolation support 10. The erection beam 31 is installed on a height adjustment part 5 attached to the frame part 24 of the traveling unit 22. In other words, the erection beam 31 is configured to move up and down in accordance with the vertical movement of the height adjustment part 5.

[0033] The support beam 32 is made of steel and has a length that spans the pair of erection beams 31, 31. The support beam 32 comprises a support beam body 33 and locking portions 34 formed at both ends of the support beam body 33. The support beam 32 is configured to move horizontally while being locked to the pair of erection beams 31, 31. The horizontal movement structure will be described later. The pair of support beams 32, 32 are moved horizontally while being locked to the pair of erection beams 31, 31 and are held in a position below the stepped portions 14 formed on both sides in the width direction of the seismic isolation support 10.

[0034] A holding part 35 is provided to maintain the distance between a pair of support beams 32, 32 arranged on both sides in the width direction of the seismic isolation bearing 10. The holding part 35 is a steel rod-shaped member. The holding part 35 is inserted through a through hole 36 formed in the support beam body 33 and is configured to be fixable to the support beam body 33. The fixing structure between the holding part 35 and the support beam body 33 is, for example, a structure that uses nuts to fasten with screws, but other structures may also be used. The holding part 35 maintains the distance between the pair of erecting beams 31, 31 when the pair of erecting beams 31, 31 are located below the stepped portion 14 of the seismic isolation bearing 10.

[0035] As shown in Figure 6, the height adjustment unit 5 is interposed between the running unit 2 and the support unit 3, and is provided to adjust the height of the support unit 3 relative to the running unit 2. The height adjustment unit 5 has a base 51 provided on the upper surface of the frame 24 of the running unit 22, a jack 52 positioned above the base 51, and a mounting unit 53 positioned above the jack 52.

[0036] The base 51 is a substantially cylindrical member capable of housing the cylinder of the jack section 52. The base 51 is installed on the upper surface of the frame section 24.

[0037] The jack section 52 has a mounting section 53 connected to its upper part. The jack section 52 is configured to be extendable and retractable in the vertical direction. The jack section 52 is positioned between the traveling section 2 and the support section 3, and when the jack section 52 is extended, the seismic isolation bearing 10 is lifted from the concrete foundation 11 together with the support section 3.

[0038] The mounting section 53 is a roughly plate-shaped steel member connected to the upper part of the jack section 52. The end of the erection beam 31 is placed on the upper surface of the mounting section 53. A recess 54 is formed on the upper surface of the mounting section 53 along the width direction. The recess 54 is sized to accommodate the erection beam 31. The mounting section 53 and the erection beam 31 are connected, for example, using bolts and nuts, but the connection structure is not limited to this.

[0039] The rails 6 are installed on both sides in the width direction of the seismic isolation bearing 10. The rails 6 extend to both sides in the width direction of the concrete foundation 11A to which the seismic isolation bearing 10 is moved. The rails 6 consist of a rail body 61, a connecting part 62 that connects rails 6 that extend in the direction of movement of the seismic isolation bearing 10, and a holding part 63 that connects rails 6 arranged on both sides in the width direction of the seismic isolation bearing 10.

[0040] The rail body 61 is a flat steel plate formed in a straight line. The top and sides of the rail body 61 are formed as smooth surfaces, and are processed to facilitate the rolling of the wheels 21.

[0041] The connecting section 62 is a structure that connects rails 6 that are connected in the direction of movement of the seismic isolation support 10. The connecting section 62 employs a structure that allows connection without the use of bolts or the like. The connecting section 62 is made of steel and is provided on the outside in the width direction of the rail body 61. It is structured so that the connecting section 62A of one rail 6A can be connected to the connecting section 62B of the other rail 6B. In other words, a connecting section 62A is formed at one end of a single rail 6, and a connecting section 62B is formed at the other end.

[0042] The connecting portion 62A comprises a base portion 65 formed by connecting to the outside in the width direction of the rail body 61, a base portion 66 disposed on the upper surface of the base portion 65, a protruding piece 67 disposed on the upper surface of the base portion 66, and a locking piece 68 disposed on the outside in the width direction of the protruding piece 67.

[0043] The base portion 65 is a plate-shaped member connected and fixed to the outer side surface in the width direction of the rail body 61, for example by welding. The thickness of the base portion 65 and the thickness of the rail body 61 are approximately the same. The base portion 66 is a plate-shaped member positioned on the upper surface of the base portion 65. The base portion 65 and the base portion 66 are fixed together, for example by bolts, but the fixing structure may also be welding or other methods.

[0044] The protruding piece 67 is positioned on the upper surface of the base 66 and is positioned to protrude further than the extension end of the rail body 61. A through hole 69 is formed in the protruding portion of the protruding piece 67 through which the key member 70, described later, is inserted. The through hole 69 is rectangular in shape and extends through in the width direction. The protruding piece 67 is fixed to the base 66, but the fixing structure is arbitrary.

[0045] The locking piece 68 is located on the upper surface of the base 66 and is provided on the widthwise outer side of the protruding piece 67. The locking piece 68 is fixed to the base 66, but the fixing structure is arbitrary. The locking piece 68 has a main body portion 71 arranged along the side surface of the protruding piece 67, an extension portion 72 that bends at approximately a right angle from the extension end of the main body portion 71 and extends outward in the widthwise direction, and a locking portion 73 that bends at approximately a right angle from the widthwise outer end of the extension portion 72 and extends approximately parallel to the main body portion 71. The locking piece 68 is formed in a roughly J-shape in plan view. The locking piece 68 is configured to lock onto the fixing piece 76 of the fixing member 75, which will be described later.

[0046] The connecting portion 62B comprises a base portion 78 formed by connecting to the outside of the rail body 61 in the width direction, and a fitting portion 79 positioned on the upper surface of the base portion 78.

[0047] The base portion 78 is a plate-shaped member that is connected and fixed to the outer side surface in the width direction of the rail body 61, for example by welding. The thickness of the base portion 78 and the thickness of the rail body 61 are approximately the same.

[0048] The fitting portion 79 is a member positioned on the upper surface of the base portion 78. The base portion 78 and the fitting portion 79 are fixed together, for example, by bolts, but the fixing structure may also be welding or the like. The fitting portion 79 comprises a plate-shaped base portion 80 that abuts against the base portion 78, and a projection portion 81 that protrudes upward from the end of the base portion 80.

[0049] The projection 81 extends approximately vertically upward from the base 80. The projection 81 extends from two locations at both ends in the width direction of the base 80. In other words, a pair of projections 81, 81 are formed from the base 80. A gap 82 is formed between the pair of projections 81, 81. The projection piece 67 of the connecting portion 62A is configured to be inserted through the gap 82. On the side of the projection 81 on which the rail body 61 of the rail 6B extends, a U-shaped recess 83 is formed along the entire width direction. A part of the key member 70 is configured to be fitted into the recess 83.

[0050] The key member 70 is a steel plate-shaped member having a length approximately the same as the widthwise length of the fitting portion 79. A fitting recess 85 is formed in the key member 70. The fixing piece 76 of the fixing member 75 is configured to be fitted into the fitting recess 85. The side of the key member 70 opposite to the side where the fitting recess 85 is formed is sized to fit into the recess 83 of the fitting portion 79.

[0051] The fixing member 75 is a steel member that connects and fixes adjacent rails 6 together. The fixing member 75 is formed in a roughly U-shape and comprises a rectangular parallelepiped main body 77 and a pair of fixing pieces 76, 76 extending from both ends of the main body 77 in a direction perpendicular to the main body 77. The fixing pieces 76 are configured to fit into the locking piece 68 of the connecting portion 62A and the fitting recess 85 of the connecting portion 62B. Figure 4 shows the connected state of adjacent rails 6.

[0052] Figure 10 shows an example of a horizontal movement structure 40 for a support beam 32. The horizontal movement structure 40 for the support beam 32 has a rack section 41 attached to the side of the erection beam 31 and a pinion section 42 attached to the support beam 32.

[0053] The rack section 41 has teeth cut into the side surface of a flat plate-shaped member and is mounted along the extension direction of the erection beam 31. The pinion section 42 is a gear member provided at the end of the locking section 34 of the support beam 32. A rotating shaft section 43 is provided above the locking section 34 to rotate the pinion section 42 around its axis. By rotating the rotating shaft section 43 around its axis by some means, the pinion section 42 also rotates simultaneously in the same direction. Because the gear section of the pinion section 42 and the teeth cut into the rack section 41 mesh, the support beam 32 can be moved horizontally relative to the erection beam 31.

[0054] Next, we will explain how to move the seismic isolation bearing 10 using the structural relocation device 1. As shown in Figure 2, first, the rails 6 are placed on both sides in the width direction of the seismic isolation support 10. In this embodiment, the rails 6 are placed on both sides in the width direction of the seismic isolation support 10 and extend to both sides in the width direction of the concrete foundation 11A to which the seismic isolation support 10 will be moved. At this time, the rails 6 that are connected along the direction of movement of the seismic isolation support 10 are connected in the structure shown in Figures 3 and 4.

[0055] To connect the rails 6, first, the protruding piece 67 of rail 6A is inserted into the gap 82 of rail 6B so that the rail bodies 61, 61 come into contact with each other. Next, the locking member 70 is inserted into the through hole 69 of the protruding piece 67. At this time, the fitting recess 85 of the locking member 70 is positioned on the outside in the width direction and on the side where the rail body 61 of rail 6B extends. The locking member 70 is also fitted into the recess of the protruding piece 81. After the locking member 70 is attached, the fixing member 75 is attached. At this time, one fixing piece 76 of the fixing member 75 is positioned to lock into the locking piece 68 of the connecting part 62A, and the other fixing piece 76 is positioned to fit into the fitting recess 85 of the connecting part 62B. Once the fixing member 75 is attached to the predetermined position, rails 6A and 6B are connected.

[0056] Next, a retaining part 63 is attached to maintain the distance between the rails 6 arranged on both sides in the width direction of the seismic isolation support 10. The retaining part 63 can be attached at any position, and when the seismic isolation support 10 moves, the retaining part 63 provided in front of the direction of travel of the seismic isolation support 10 moves its position as appropriate to maintain a constant distance between the rails 6 arranged on both sides in the width direction.

[0057] As shown in Figures 5 and 6, after the rail 6 has been installed, the running unit 2 is installed on the rail 6. First, the running unit 22 is positioned so that it is approximately parallel to the rail 6, and the wheel body 25 of the wheel 21 is placed on the upper surface of the rail 6. After positioning the running units 22 on both sides in the width direction of the seismic isolation bearing 10, the pair of running units 22, 22 are connected to each other. The structure for attaching the connecting part 23 to the pair of running units 22, 22 is approximately the same as the connecting part 62 of the rail 6, and the connecting part 23 and the running unit 22 are connected without using screws or the like. The connecting part 23 is attached to both the front and rear sides in the direction of movement of the seismic isolation bearing 10. By attaching the connecting part 23 to the running unit 22, the running unit 22 can run stably on the rail 6.

[0058] Next, install the support section 3. As shown in Figures 7 and 8, first the temporary support beam 31 of the support section 3 is installed. The temporary support beam 31 is attached to the upper part of the height adjustment section 5 which is pre-attached to the frame section 24 of the travel unit 22. Specifically, the temporary support beam 31 is positioned by fitting it into the recess 54 formed on the upper surface of the mounting section 53 of the height adjustment section 5, and the temporary support beam 31 and the mounting section 53 are fixed using fasteners such as bolts. The temporary support beam 31 is installed at two locations, front and rear in the direction of movement of the seismic isolation bearing 10. After installing the temporary support beam 31, a pair of support beams 32, 32 is installed. The locking parts 34 formed at both ends of the support beam 32 are locked to the pair of temporary support beams 31, 31. The support beams 32 are installed at two locations on both sides in the width direction of the seismic isolation bearing 10. The pair of support beams 32, 32 are moved to a position below the stepped sections 14 formed on both sides in the width direction of the seismic isolation bearing 10. In this state, the holding parts 35 are attached to the pair of support beams 32, 32 to fix the positions of the pair of support beams 32, 32. The holding parts 35 are inserted through the through holes 36 formed in the pair of support beams 32, 32 and then secured using fasteners such as nuts.

[0059] Once the installation of the support section 3 is complete, the installation of the structural relocation device 1 is complete. After the installation of the structural relocation device 1 is complete, the relocation of the seismic isolation bearing 10 begins. First, the jack section 52 of the height adjustment section 5 is operated to move the support section 3 upward. As the support section 3 moves upward, the pair of support beams 32, 32 come into contact with the stepped section 14 of the seismic isolation bearing 10, and as the support section 3 moves further upward, the seismic isolation bearing 10 can be lifted from the concrete foundation 11 via the pair of support beams 32, 32.

[0060] With the seismic isolation bearing 10 lifted from the concrete foundation 11, the seismic isolation bearing 10 is moved. The seismic isolation bearing 10 moves in a predetermined direction by moving the structural movement device 1 along the rail 6.

[0061] The structural relocation device 1 is moved along the rail 6, and when the seismic isolation bearing 10 reaches above the concrete foundation 11A at the destination, the movement of the structural relocation device 1 is stopped. Once the seismic isolation bearing 10 has been moved to the predetermined position in a plan view, the jack section 52 of the height adjustment section 5 is operated to lower the seismic isolation bearing 10 onto the concrete foundation 11A. Once the seismic isolation bearing 10 is installed on the concrete foundation 11A, the seismic isolation bearing 10 is fixed to the concrete foundation 11A, and the movement of the seismic isolation bearing 10 is completed.

[0062] (Direction adjustment section) In the above embodiment, the seismic isolation bearing 10 was moved without adjusting its orientation in the horizontal plane. However, in some cases, it may be necessary to adjust the orientation of the seismic isolation bearing 10 when moving it. The device (mechanism) for such cases will be described below.

[0063] The structural movement device 1 of this embodiment includes a direction adjustment unit 100 for adjusting the orientation of the seismic isolation bearing 10 in the horizontal plane. Three mechanisms for adjusting the orientation of the seismic isolation bearing 10 are described below, but it is sufficient to have at least one of these mechanisms.

[0064] As shown in Figure 11, the first mechanism of the orientation adjustment unit 100 is a rotation mechanism 101. The rotation mechanism 101 is a jig formed in an annular shape and configured to be rotatable in a horizontal plane. The rotation mechanism 101 can rotate an object (seismic isolation support 10) installed on its upper surface in a horizontal plane.

[0065] Specifically, the seismic isolation bearing 10 is moved by the structural relocation device 1 to a position directly above the rotation mechanism 101. At this point, the height adjustment unit 5 is adjusted to temporarily place the seismic isolation bearing 10 on the upper surface of the rotation mechanism 101. As shown in Figure 12, once the seismic isolation bearing 10 is placed on the rotation mechanism 101, it can be rotated in the horizontal plane, allowing the orientation of the seismic isolation bearing 10 to be finely adjusted to a predetermined orientation. With the seismic isolation bearing 10 in the predetermined orientation, the height adjustment unit 5 (not shown in Figure 12) is adjusted again to lift the seismic isolation bearing 10, and the structural relocation device 1 moves the seismic isolation bearing 10 to the concrete foundation 11A.

[0066] Next, as shown in Figure 13, we will explain the mechanism for fine-tuning the orientation of the seismic isolation bearing 10 in the horizontal plane on the concrete foundation 11.

[0067] Next, we will describe the bolt adjustment mechanism 102, which is a second mechanism of the direction adjustment unit 100. As shown in Figures 14 and 15, the bolt adjustment mechanism 102 is provided at both ends of the support beam 32. The bolt adjustment mechanism 102 comprises a main body 121 provided at the end of the support beam 32, a fixing bolt 122 attached to the main body 121, a fixing part 123 provided separately from the main body 121 and fixed to the erection beam 31, and an adjustment bolt 124 attached to the fixing part 123.

[0068] The bolt adjustment mechanism 102 is configured to fix the support beam 32 to the erection beam 31 by tightening the fixing bolt 122 attached to the main body 121. Conversely, loosening the fixing bolt 122 releases the support beam 32 from being fixed to the erection beam 31.

[0069] The bolt adjustment mechanism 102 is provided at a total of four locations at both ends of the pair of support beams 32, 32.

[0070] Here, we will explain how to adjust the orientation of the seismic isolation bearing 10 within the horizontal plane.

[0071] Of the four bolt adjustment mechanisms 102, the fixing bolt 122 at the center of rotation for fine adjustment is tightened to fix the support beam 32 to the erection beam 31. At this time, the fixing bolts 122 of the remaining three bolt adjustment mechanisms 102 are loosened to release the support beam 32 from the erection beam 31. In addition, a fixing part 123 is installed immediately next to the main body 121 of the unfixed bolt adjustment mechanism 102. The fixing part 123 is fixed to the erection beam 31 by some method.

[0072] In this state, by tightening the adjustment bolt 124 of one of the unfixed bolt adjustment mechanisms 102, for example, the adjustment bolt 124 of the bolt adjustment mechanism 102 located diagonally opposite the fixed bolt adjustment mechanism 102, the tip of the adjustment bolt 124 can be used to push the main body 121. This allows the seismic isolation bearing 10 to be rotated in the horizontal plane around the fixed bolt adjustment mechanism 102, thereby fine-tuning the orientation of the seismic isolation bearing 10 in the horizontal plane. After repeating the same process and adjusting the seismic isolation bearing 10 to a predetermined orientation, the structural movement device 1 can be used to move the seismic isolation bearing 10 toward the concrete foundation 11A.

[0073] Next, the roller adjustment mechanism 103, which is a third mechanism of the direction adjustment unit 100, will be described. As shown in Figure 16, the roller adjustment mechanism 103 comprises a fixed part 131 fixed to the seismic isolation bearing 10, a bearing support member 132 attached to the fixed part 131, and a roller member 133 provided on the erected beam 31.

[0074] The roller adjustment mechanism 103 has a support member 132 fixed to a fixing part 131 which is fixed to the seismic isolation bearing 10 using bolts 134. The support member 132 is a roughly plate-shaped member and is formed to span over the upper part of the erected beam 31. The roller material 133 comprises a roughly plate-shaped main body 135 and rollers 136 attached to the main body 135. The roller material 133 is configured to be movable along the erected beam 31. In addition, the upper surface of the main body 135 is flat and is configured to be in contact with the lower surface of the support member 132.

[0075] Here, we will explain how to adjust the orientation of the seismic isolation bearing 10 within the horizontal plane.

[0076] First, the fixing part 131 is fixed to the seismic isolation bearing 10. The bearing support member 132 may be fixed to the fixing part 131 in advance, or the bearing support member 132 may be attached after the fixing part 131 is fixed to the seismic isolation bearing 10. Next, the roller material 133 is installed on the erection beam 31, and the roller material 133 is installed so that it is located below the bearing support member 132. Note that, as shown in Figure 16, one roller material 133 may be provided for each bearing support member 132, or the length of the main body 135 of the roller material 133 may be increased so that one roller material 133 is provided for two bearing support members 132.

[0077] By adjusting the height adjustment section 5, the bearing support member 132 is placed on the upper surface of the main body 135 of the roller material 133, and the roller material 133 is moved along the erected beam 31, thereby fine-tuning the seismic isolation bearing 10 to a predetermined orientation. After the seismic isolation bearing 10 has been adjusted to the predetermined orientation, the structural movement device 1 can move the seismic isolation bearing 10 toward the concrete foundation 11A.

[0078] The structural relocation device 1 of this embodiment is a structural relocation device 1 used when moving a seismic isolation bearing 10, and is integrally configured with a traveling unit 2 that moves the seismic isolation bearing 10 in a predetermined direction, a support unit 3 that supports the seismic isolation bearing 10, and a height adjustment unit 5 interposed between the traveling unit 2 and the support unit 3, which can adjust the height of the support unit 3 relative to the traveling unit 2, and the traveling unit 2 is configured to be able to travel on a pair of rails 6, 6 provided on both sides of the seismic isolation bearing 10.

[0079] With this configuration, the seismic isolation bearing 10 can be easily moved simply by operating the structural relocation device 1. Furthermore, since the structural relocation device 1 is equipped with rails 6, the seismic isolation bearing 10 can be reliably guided to a predetermined direction (position) when being transported. In other words, the seismic isolation bearing 10 can be moved efficiently without relying on the experience of skilled workers.

[0080] In this embodiment, the structural moving device 1 includes a support section 3 that extends in a direction perpendicular to the rail 6 in a plan view and is provided on both sides of the seismic isolation bearing 10, and a pair of support beams 32, 32 that span across the pair of support beams 31, 31 and are capable of supporting the seismic isolation bearing 10. Therefore, by supporting the seismic isolation bearing 10 between the pair of support beams 32, 32, the seismic isolation bearing 10 can be reliably held from both sides.

[0081] Furthermore, in this embodiment, the structural relocation device 1 has a height adjustment unit 5 equipped with a jack unit 52, which allows the seismic isolation support 10 to be reliably lifted to a predetermined height.

[0082] Furthermore, by providing the orientation adjustment unit 100 in the structural movement device 1, the seismic isolation bearing 10 can be moved while maintaining a predetermined orientation in the horizontal plane. In other words, the seismic isolation bearing 10 can be moved efficiently in a predetermined orientation without relying on the experience of skilled workers.

[0083] Furthermore, the orientation adjustment unit 100 is made into a rotating mechanism 101 that allows the seismic isolation bearing 10 to rotate in the horizontal plane, so that the orientation of the seismic isolation bearing 10 in the horizontal plane can be easily rotated and adjusted.

[0084] Furthermore, by making the orientation adjustment unit 100 a bolt adjustment mechanism 102 or roller adjustment mechanism 103 provided on the support unit 3, the orientation of the seismic isolation support 10 in the horizontal plane can be easily adjusted to a predetermined orientation without installing a separate, large-scale device.

[0085] Although embodiments of the structure moving device and structure moving method according to the present invention have been described above, the present invention is not limited to the above embodiments and can be modified as appropriate without departing from the spirit of the invention.

[0086] For example, in this embodiment, we have described a case where the support section 3 is composed of a pair of erection beams 31, 31 and a pair of support beams 32, 32, but the configuration is not limited to this as long as it can support the seismic isolation bearing 10 (structure).

[0087] Furthermore, in this embodiment, the height adjustment unit 5 is configured as a jack device (jack unit 52), but any mechanism capable of height adjustment other than a jack device may be used.

[0088] Furthermore, this embodiment does not particularly limit the method of driving the travel unit 2. In other words, the travel unit 2 may be driven manually, electrically driven using a motor or the like, or auxiliaryly electrified by an external electric impact or the like.

[0089] Furthermore, although not particularly limited in this embodiment, the running section 2 may be equipped with a brake structure to prevent runaway even in areas with a gradient.

[0090] Furthermore, although this embodiment describes the case of moving the seismic isolation bearing 10, the object to be moved may be something other than the seismic isolation bearing 10. In addition to moving the seismic isolation bearing 10, it can also be used, for example, when removing and moving an existing seismic isolation bearing 10 and then transporting and installing a new seismic isolation bearing using the structural relocation device 1. In other words, the structural relocation device 1 can also be used for structural replacement work.

[0091] Furthermore, the "Sustainable Development Goals (SDGs)" are among the 17 international goals adopted at the UN Summit in September 2015. The structure moving device and structure moving method according to this embodiment can contribute to achieving some of the 17 SDGs, such as Goal 9, "Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation."
