As shown in FIG. 1, a support structure 1 to which the present invention is applied includes a support device 10 disposed between an upper structure 2 such as a bridge girder and a lower structure 3 such as a bridge pier or an abutment, and the support device 10. And a sliding member 11 that slides on the supporting device 10 and a guide member 12 that supports the supporting device 10 so as to be slidable and guides the sliding device 10 during sliding. Yes.

[2. Description of bearing device]
As shown in FIG. 1, the support device 10 is mounted between an upper structure 2 such as a bridge girder and a lower structure 3 such as a bridge pier or an abutment to support various loads such as a horizontal load, a vertical load, and a rotational load. At the same time, it is a bridge support device that supports and absorbs and disperses vibrations, vibrations and stresses caused by earthquakes, winds, dynamic or static traffic loads, and the like. Of course, the bearing device 10 of the present invention is not limited to application to bridges, and can be applied as a bearing device for an appropriate structure such as a building, a building, or a cultural property. In the support device 10, an elastic body 22 serving as a support body is interposed between an upper collar 20 serving as a first rigid body and a lower collar 21 serving as a second rigid body. The elastic body 22 is surrounded by a restraining body 23 fixed to the upper collar 20 or the lower collar 21 (here, the upper collar 20).

  The upper collar 20 is preferably made of a rigid material such as metal, ceramics, or a reinforced resin such as hard resin or FRP, but is not necessarily limited to a rigid material. It can also be configured by a material combining the above. The upper collar 20 composed of various materials can be set to an appropriate shape such as a substantially polygonal shape, a substantially circular shape, a substantially oval diameter, or a substantially oval shape in plan view. It is advantageous in terms of dynamics, manufacturing, construction, and replacement to be square. In addition, you may comprise the upper collar | cover 20 so that an outer surface may be entirely covered with coating layers, such as an elastic body, and a weather resistance and an antirust effect may be acquired. Such an upper collar 20 is slidably supported on the upper structure 2 by the guide member 12 with the sliding member 11 interposed therebetween.

  In FIG. 1, the upper rod 20 is formed so that the length in the direction perpendicular to the bridge axis (width direction) is substantially the same as the length in the width direction of the upper structure 2, but is not limited thereto. Instead, the length in the width direction may be shorter than the length in the width direction of the upper structure 2 or may be longer.

  Like the upper collar 20, the lower collar 21 is preferably made of a rigid material such as metal, ceramics, or a reinforced resin such as a hard resin or FRP, but is not necessarily limited to a rigid material. It can also be made of a material or a combination of a rigid material and an elastic material. The lower eyelid 21 made of various materials can be set to an appropriate shape such as a substantially polygonal shape, a substantially circular shape, a substantially oval diameter, or a substantially oval shape in plan view. It is advantageous in terms of mechanics, manufacturing, construction, and replacement to be square. The planar shape or the like of the lower eyelid 21 does not necessarily match the upper eyelid 20, but the size of each part, the shape and position of the convex portion and the recessed portion, and the like are matched to each other. It is necessary to let It should be noted that the lower arm 21 can also be configured so as to obtain a weather resistance and a rust prevention effect by covering the entire outer surface with a coating layer such as an elastic body.

  Further, the lower rod 21 is fixed to the lower structure 3 by a fixing member 4 such as an anchor bolt or a nut. At this time, the lower rod 21 may be directly fixed to the lower structure 3, but here, the lower plate 21 is formed in a lower portion by using a lower plate 24 having a plate shape larger than the lower rod 21. It is indirectly fixed to the structure 3. The method for fixing the lower rod 21 to the lower structure 3 is not limited to these examples. Note that the direct or indirect fixing of the lower rod 21 is preferably a detachable method, and fastening with anchor bolts, nuts, or the like is one example.

[3. Explanation of elastic body and restraint body]
The elastic body 22 used here is, for example, an elastic body having a laminated structure in which an elastic layer 22a and a reinforcing plate 22b are laminated. The elastic body 22 includes a reinforcing plate 22b, a plurality of elastic layers 22a, and the reinforcing plate 22b and the elastic layer 22a are bonded to each other by vulcanization bonding. In addition, the upper and lower surfaces of the elastic body 22 are reinforced by vulcanizing and bonding the upper plate 22c and the lower plate 22d.

  Here, as the elastic layer 22a, natural rubber, synthetic rubber, thermoplastic elastomer or thermosetting elastomer can be used, and among these, natural rubber is preferably used as a main component. Specific elastomer components include, for example, natural rubber (NR), polyisoprene rubber (IR), polybutadiene rubber (BR), styrene-butadiene rubber (SBR), chloroprene rubber (CR), ethylene-propylene rubber, butyl rubber ( IIR), halogenated butyl rubber (brominated, chlorinated, etc.), acrylic rubber, polyurethane, silicone rubber, fluorinated rubber, polysulfide rubber, hyperon, ethylene vinyl acetate rubber, epichlorohydrin rubber, ethylene-methyl acrylate copolymer, styrene series Elastomer, urethane elastomer, polyolefin elastomer, acrylonitrile-butadiene rubber (NBR), styrene-isoprene-styrene block copolymer (SIS), epoxidized natural rubber, trans-polyisoprene, norbornene Ring polymer (polynorbornene), styrene-butadiene rubber (SBR), high styrene resin, a rubber such as isoprene rubber alone, or may be used in combination of two or more. The reinforcing plate 22b, the upper plate 22c, and the lower plate 22d are made of a rigid steel material such as an iron plate. In the laminated elastic body 22 as described above, when a load is applied, the side surface of the elastic layer 22a between the reinforcing plates 22b, which are free side surfaces, slightly bulges laterally according to the magnitude of the load. It has the characteristic to do.

  Around the elastic body 22, a convex portion 25 and a concave portion 26 are provided in the circumferential direction. In the example of FIG. 1, the convex portion 25 and the concave portion 26 are provided in parallel to each other and continuously in the circumferential direction. Of course, the convex portion 25 and the concave portion 26 may be provided intermittently in the circumferential direction. In particular, in the elastic body 22, the convex part 25 is provided in the side surface of the elastic layer 22a used as a free side surface, and the recessed part 26 is provided in the position of the reinforcement board 22b. Of course, conversely, the concave portion 26 may be provided at the position of the elastic layer 22a, and the convex portion 25 may be provided at the position of the reinforcing plate 22b.

  The elastic body 22 as described above is disposed and supported by the large-diameter portion 28 of the core member 27 fixed to the lower collar 21. The elastic body 22 may be bonded between the upper collar 20 and the lower collar 21 to increase the bearing pressure. However, by not bonding, the elastic body 22 can also realize good rotation followability.

  In the above example, the case where the elastic body 22 is a laminated type has been described. However, as shown in FIG. One (single layer) elastic layer that is not provided with a rigid reinforcing plate such as an iron plate may be used. Moreover, as shown in FIG. 3, as the elastic body 22, you may provide the convex part 25 and the recessed part 26 in the height (thickness) direction. In the example of FIG. 3, the elastic layer may be a single layer, but may be a laminated type having a reinforcing plate as in the example of FIG. Furthermore, as shown in FIG. 4, the elastic body 22 which does not have the convex part 25 and the recessed part 26 on the side surface may be sufficient. In this case as well, the elastic body 22 may be a single layer elastic layer or may be a laminated type having a reinforcing plate. In addition, the size of the elastic body 22 in FIGS. 1 to 4 may be a size that fits into the restraining body 23 when inserted into the restraining body 23. A gap may be provided between the restraining surface 23 a and the side surface of the elastic body 22. Furthermore, in the example of FIG. 4, the convex portion 25 and / or the concave portion 26 may be provided on the restraining surface 23 a of the restraining body 23. In the following description, the laminated elastic body 22 having the convex portions 25 and the concave portions 26 shown in FIG. 1 will be described as an example.

  The elastic body 22 configured as described above is surrounded by a restraining body 23 as shown in FIG. The restraining body 23 is a cylindrical body having an inner diameter slightly larger than the outer diameter of the elastic body 22, and is fixed to either the upper collar 20 or the lower collar 21, or the upper collar 20 in FIG. For example, the restraining body 23 is fixed to the upper collar 20 by a fixing member 29 such as a screw fastening body. In addition, the restraining body 23 may be fixed to either the upper eyelid 20 or the lower eyelid 21 by welding, a conventionally known fixing method, or the like.

  Further, a core material 27 is fixed to the lower rod 21 to form an uplift prevention portion and a horizontal displacement prevention portion. Specifically, the core material 27 has a lower end fixed to the lower collar 21 serving as a base plate. The core member 27 is made of a metallic bolt-shaped member having a head portion that becomes the large-diameter portion 28, and the large-diameter portion 28 that is the tip portion is disposed in the restraining body 23 so that the elastic body 22 is substantially sealed. It functions like a piston that restrains and increases bearing pressure. The core member 27 is fixed by being screwed into the screw hole 30 of the lower collar 21. The structure for fixing the core material 27 to the lower collar 21 is not limited to this. For example, a fixing bolt inserted into the screw hole of the core material 27 from the lower surface of the lower collar 21 is screwed. You may make it do. The large-diameter portion 28 may also be fixed by, for example, screwing a screw portion provided at the tip of the core material 27 into a screw hole of the large-diameter portion of another member.

  The large-diameter portion 28 integrated with the core member 27 engages with an anti-lifting piece 32 fixed to the lower surface of the restraining body 23 by a fixing member 31 such as a screw. The large diameter portion 28 of the core member 27 integral with the lower rod 21 serves as a lifting prevention portion, and when an upper lifting force is applied to the upper collar 20, the lifting prevention piece 32 on the upper collar 20 side is locked. This prevents the upper rod 20 and the lower rod 21 from separating. That is, the large-diameter portion 28 of the core material 27 is disposed in the restraining body 23, thereby allowing the elastic body 22 to be displaced in the vertical direction and serving as a horizontal displacement preventing portion. Regulate horizontal displacement. Thereby, it is possible to prevent the upper rod 20 and the lower rod 21 from being excessively displaced in the horizontal direction. Further, a gap is provided between the lifting prevention piece 32 and the lower rod 21, and when the upper rod 20 moves to the lower rod 21 side by being displaced vertically downward, the lifting prevention piece 32 is lowered. It does not hit the heel 21. The lifting prevention piece 32 may be fixed to the restraining body 23 by welding, a conventionally known fixing method, or the like, in addition to using the fixing member 31.

  In other words, the support device 10 is provided with a restraining body 23 on the upper collar 20 side and a core member 27 having a large-diameter portion 28 that is provided on the lower collar 21 side and supports the elastic body 22. The function of suppressing the shear deformation of 22 and the role of a piston that restrains the elastic body 22 in a substantially hermetically sealed state to increase the bearing pressure, and the upper surface of the elastic body 22 supported by the lower collar 21 is the upper collar 20 The side surface is surrounded by the restraining body 23 and disposed in a semi-sealed space. The bearing device 10 is a semi-sealed rubber bearing, and can support a high load with a small bearing area while allowing a vertical deflection required for rotation in a vertical plane.

  The assembly method of the support device 10 will be described. A core material 27 is inserted into the restraining body 23 and the core material 27 is fixed to the screw hole 30 of the lower collar 21. Thereby, a pot portion for accommodating the elastic body 22 is formed in the restraining body 23 by the large diameter portion 28. Thereafter, the elastic body 22 is disposed on the core material 27 in the pot portion. Thereafter, the upper collar 20 is coupled to the restraining body 23 by a fixing member 29. Of course, the assembly method of the support device 10 is not limited to the above example.

  It should be noted that a lubricant may be filled between the elastic body 22 and the restraining body 23 to reduce friction so that the elastic body 22 can be smoothly vertically displaced within the restraining body 23. Alternatively, the constraining surface 23 a of the constraining body 23 may be mirror-finished to reduce friction so that the elastic body 22 can be smoothly vertically displaced within the constraining body 23.

  Here, the relationship between the size of the elastic body 22 and the restraining body 23 will be described. In the example of FIG. 1, the support device 10 is installed between the upper structure 2 and the lower structure 3, and In a state where the elastic body 22 is deformed by the load of the upper structure 2 (for example, a state in which a dead load is applied), the convex portion 25 on the side surface of the elastic body 22 contacts the restraining surface 23a on the inner peripheral surface of the restraining body 23. It is configured to be in contact. That is, before being installed between the upper structure 2 and the lower structure 3, the convex portion 25 on the side surface of the elastic body 22 is not in contact with the restraining surface 23 a on the inner peripheral surface of the restraining body 23. Thus, when the gap is provided, and is installed between the upper structure 2 and the lower structure 3, the convex portion 25 on the side surface of the elastic body 22 is caused by the dead load of the upper structure 2. It will be in the state contact | abutted to the restraint surface 23a of the internal peripheral surface of the restraint body 23. FIG. When a dead load is loaded, the convex portion 25 on the side surface of the elastic body 22 is not in contact with the constraining surface 23a on the inner peripheral surface of the constraining body 23, and a high load exceeding the normal use range (for example, traffic such as a large vehicle) When there is a live load due to the load, the convex portion 25 on the side surface of the elastic body 22 abuts on the constraining surface 23a on the inner peripheral surface of the constraining body 23, and the convex portion 25 on the constraining surface 23a by the input of a further high load. In addition, the bulging and deforming portion of the recess 26 may be pressed. In addition, when the convex part 25 and the recessed part 26 of the height direction are in the side surface of the elastic body 22, the elastic body 22 can be easily accommodated in the pot part in the restraint body 23. FIG.

[4. Explanation of operation of bearing device]
In the support device 10 as described above, when installed between the upper structure 2 and the lower structure 3, as shown in FIG. 1, the elastic body 22 has a load in a normal use range (for example, dead load or (Dead load + live load during vehicle travel) is compressed, and the convex portion 25 of the elastic body 22 is positioned close to or in contact with the restraining surface 23a of the restraining body 23 surrounding the elastic body 22. In the support device 10, the elastic body 22 is elastically deformed according to the magnitude of the vertical load, and the elastic body 22 is deformed so that the convex portion 25 on the side surface fills the gap formed by the concave portion 26. Is pressed against the restraining surface 23a. That is, the displacement amount of the elastic body 22 is limited by the restraining body 23.

  Furthermore, the relationship between the convex portion 25 and the concave portion 26 of the elastic body 22 and the restraining surface 23a of the restraining body 23 will be described. The laminated elastic body 22 is provided with the convex portion 25 at the position of the elastic layer 22a on the free side surface. A recess 26 is provided at the position of the reinforcing plate 22b. In this case, when the load is applied, the convex portion 25 is strongly pressed against the constraining surface 23a of the constraining body 23 before the concave portion 26 because the free side surface of the elastic layer 22a bulges. In the laminated elastic body 22, a convex portion 25 is provided on the elastic layer 22 a at a position between the reinforcing plates having the largest bulging amount in the past, and the bulging amount around the convex portion 25 is formed by the constraining surface 23 a of the constraining body 23. Therefore, even when a high load is input, local stress on the elastic layer 22a around the internal reinforcing plate 22b is relieved. Further, the internal reinforcing plate 22b is not easily crushed by a high load, the reinforcing plate 22b can be thinned, and the entire thickness of the support device 10 can be realized. The position of the reinforcing plate 22b may be the convex portion 25 and the position of the elastic layer 22a may be the concave portion 26. In this case, since the free side surface of the elastic layer 22a which is a concave portion slightly bulges, the convex portion 25 and the concave portion 26 are similarly brought into contact with the constraining surface 23a of the constraining body 23 and are evenly pressed. You can make it.

  The support device 10 is provided with a restraining body 23 on the upper collar 20 side and a core member 27 having a large diameter portion 28 that is provided on the lower collar 21 side and supports the elastic body 22. The part 28 realizes the function of suppressing the shear deformation of the elastic body 22 disposed between the upper rod 20 and the lower rod 21, and the role of a piston that restrains the elastic body 22 in a substantially sealed state to increase the bearing pressure. The elastic body 22 supported by the lower rod 21 is surrounded by the upper rod 20 on the upper surface and the restraining body 23 on the side surface, and is disposed in a semi-sealed space. While enabling vertical deflection required for in-plane rotation, it is possible to support a high load with a small bearing area.

  In addition, when the rotational force is applied in the vertical plane from the low load to the high load, the elastic body 22 is supported by the gap between the convex portion 25 or the concave portion 26 while the elastic body 22 is partially supported by the restraining body 23. It can be deformed, and good rotation followability can be realized without an extreme load on the elastic body 22.

Here, FIG. 5 shows the relationship between the amount of displacement in the vertical direction and the vertical load.
Line A: General laminated rubber bearings Note that the rubber bearings here are elastic rubber laminated rubber, and a horizontal force distributed rubber bearing or seismic isolation bearing with multiple steel plates inside. This is not a sealed rubber bearing, but a bearing in which displacement when a load is applied is not constrained.
Line B ... The outer shape of the elastic body 22 is made smaller than the inner diameter of the restraining body 23 (the inner diameter of the pot portion), the convex portions 25 and the concave portions 26 are formed larger, and the restraining surface 23a and the side surface of the elastic body 22 The characteristics when the gap between them is increased are shown. (Large gap)
Line C: Characteristic when the gap between the restraining surface 23a and the side surface of the elastic body 22 is made smaller than that of the line B. (In the gap)
Line D: shows characteristics when the gap between the restraining surface 23a and the side surface of the elastic body 22 is minimized. (Small gap)
Line E: A sealed rubber bearing that does not provide a gap between the restraining surface 23a and the side surface of the elastic body 22. Although it has a rotation follow-up performance, it has almost no elastic displacement in the vertical direction and is handled as a metal bearing.

  In the present invention, any support device for line AE can be applied.

  In the rubber bearing shown by the line A in FIG. 5, as the vertical load increases, the amount of vertical displacement also increases substantially proportionally, and the slope (constraint or spring constant) of the graph is substantially constant. According to the example of the line BD in which the convex portion 25 and the concave portion 26 are provided on the side surface of the elastic body 22, the vertical displacement amount increases as the vertical load increases, but the characteristic becomes nonlinear. That is, the inclination (constraint degree or spring constant) of the graph representing the magnitude of the vertical load reaction force with respect to the vertical displacement increases as the vertical displacement increases. As described above, when the convex portion 25 and the concave portion 26 are provided on the side surface of the elastic body 22, the larger the load is inputted, the more the state is changed to a higher sealed state, and the increase amount of the vertical displacement amount is reduced. The upper structure 2 can be supported by characteristics, that is, with the degree of restraint being variable. In other words, the bearing device 10 can support a high load while having appropriate vertical flexibility. Moreover, when the example of line BD is seen, the gentle range (primary gradient) of the inclination of the graph showing the magnitude | size of the vertical load reaction force with respect to a vertical displacement can be set narrowly, so that a clearance gap is small. That is, the vertical displacement is reduced. Furthermore, in the sealed rubber bearing of line E, there is almost no elastic displacement in the vertical direction.

  In particular, according to the example of the line BD in which the convex portion 25 and the concave portion 26 are provided on the side surface of the elastic body 22, when a high load is applied, the vertical flexible displacement becomes small and behaves like a sealed rubber bearing. Therefore, in the example of the line BD, the use range of the line BD is set according to the type and application of the superstructure 2 to be supported. For example, by adding a state where a live load is added to a dead load to be included in the steep slope (secondary slope) region of the graph, the vertical deflection width due to the size of the live load can be reduced. This makes it possible to reduce vibration and noise when passing through the vehicle. In addition, in the low load area (primary gradient), since there is vertical deflection, the bearing device of line BD can be treated as belonging to the elastic bearing device.

  Further, the sliding member 11 may be fixed to the lower surface 2a of the upper structure 2 and the upper surface 20a of the upper collar 20 to further reduce the friction between the upper structure 2 and the upper collar 20. . Further, the sliding member 11 is not provided on the lower surface 2a of the upper structure and the upper surface 20a of the upper collar 20, but instead of the sliding member 11, the lower surface 2a of the upper structure and / or the upper surface 20a of the upper collar 20 is mirror-finished. Processing may be performed to reduce friction between the upper structure 2 and the upper collar 20.

[6. Explanation of guide member]
As shown in FIGS. 1 and 6, the guide member 12 is a long member having a substantially L-shaped cross section in which an engaging portion 34 of a protruding ridge projecting inward is formed on the upper end portion 12 a. Here, the guide member 12 is provided so that the length in the bridge axis direction (length direction) is substantially the same as the length of the upper rod 20 in the length direction. Such a guide member 12 is disposed, for example, so that a pair of engaging portions 34 face each other in a direction perpendicular to the bridge axis along the bridge axis direction of the upper collar 20, and the engaging portions 34 are arranged in the upper structure 2. It is being fixed to the side part 20c of the upper collar 20 by the fixing members 35, such as a screw fastening body, so that it may engage with the upper surface 2b. The guide member 12 may be provided so that the length in the length direction is shorter than the length in the length direction of the upper collar 20. In addition, the guide member 12 may be fixed to the side surface portion 20c of the upper collar 20 by welding or a conventionally known fixing method.

Thus, the upper rod 20 is slidably supported in the bridge axis direction with respect to the upper structure 2, and the upper rod 20 is guided when the upper rod 20 is slid in the bridge axis direction by the sliding member 11. The upper collar 20 is prevented from being separated from the upper structure 2. That is, the support device 10 is attached to the upper structure 2 by the guide member 12 so as to be a movable rubber support device.

  As shown in FIG. 7, the upper rod 20 is formed on a pair of stopper members 37, 37 disposed on the lower surface 2 a of the upper structure 2 and spaced apart from each other by a predetermined distance about the support device 10 in the bridge axis direction. The movement in the bridge axis direction may be regulated by abutting. For example, the stopper members 37, 37 are fixed to the lower surface 2 a of the upper structure 2 by a fixing member 36 such as a screw fastening body. In addition, the stopper members 37, 37 may be fixed to the lower surface 2a of the upper structure 2 by welding or a conventionally known fixing method.

[7. Effect]
As described above, in the support structure 1 to which the present invention is applied, the sliding member 11 disposed between the upper structure 2 and the upper collar 20 of the support device 10 slides on the support device 10. The guide member 12 provided on the side surface portion 20c of the flange 20 engages with the upper surface 2b of the upper structure 2 to support the upper flange 20 slidably with respect to the upper structure 2, and the upper flange 20 Since the guide is performed when sliding with respect to the upper structure 2, the support device 10 can be used as a movable elastic support device. Therefore, in the support structure 1 to which the present invention is applied, the elastic body 22 undergoes shear deformation while a horizontal force equal to or less than the maximum static frictional force between the support device 10 and the sliding member 11 is applied, and the support device 1 When a horizontal force greater than the maximum static frictional force between the sliding member 11 and the sliding member 11 is generated, the bearing device 10 can slide the sliding member 11 and prevent further horizontal force from acting, Large relative displacement of the upper eyelid 20 and the lower eyelid 21 of the device 10 can be absorbed.

[8. Description of modification 1 of bearing structure]
As shown in FIG. 8, in the support structure 110 of Modification 1, the engaging portion 34 of the guide member 12 is provided separately from the main body portion 12 e of the guide member 12. The engaging portion 34 is fixed to the main body portion 12e of the guide member 12 by a fixing member 38 such as a screw fastening body, for example.

  Even in such a support structure 110, the support device 10 can be easily attached to the upper structure 2 by the guide member 12 so as to be a movable rubber support device, and by the sliding member 11 and the guide member 12. The bearing device 10 can be used as a movable rubber bearing device. Furthermore, in such a support structure 110, the guide member 12 can be manufactured at a lower cost than that in which the engaging portion 34 is integrated.

[9. Description of modification 2 of bearing structure]
The support structure 120 of the second modification has a configuration as shown in FIG. In the support device 10 of the support structure 120, a through hole 121 penetrating the front and back surfaces of the upper collar 20 is formed. The core material 122 is inserted into the through-hole 121 from the upper surface side of the upper collar 20, and the amount of displacement of the upper collar 20 vertically downward without the tip portion of the core material 122 protruding from the upper surface of the upper collar 20 is considered. Thus, the tip portion is accommodated so as to be lowered one step further. At the opening end of the through-hole 121, a lifting prevention piece 121a is formed in a flange shape. The restraining body 23 is fixed to the outer peripheral portion of the upper collar 20 by a fixing member 29 as in the above-described example. The front end portion of the restraining body 23 on the lower collar 21 side is located outside the outer peripheral portion of the lower collar 21 and is not fixed. Thereby, when the vertical load is input, the upper collar 20 can be displaced vertically downward while compressing the elastic body 22. That is, the distal end portion of the restraining body 23 on the lower collar 21 side is located outside the outer periphery of the lower collar 21 so that the elastic body 22 disposed between the upper collar 20 and the lower collar 21 is subjected to shear deformation. The function to suppress and the role of the cylinder which restrains the elastic body 22 in a substantially sealed state and increases the bearing pressure are realized. Thus, the elastic body 22 supported by the lower collar 21 is disposed in a substantially sealed space with the upper surface surrounded by the upper collar 20 and the side surface by the restraining body 23. Therefore, the support device 10 of the support structure 120 is a substantially sealed rubber support, and can support a high load with a small support area.

  The core member 122 inserted through the through-hole 121 is made of a metallic bolt-shaped member having a head that becomes the large-diameter portion 123, and the large-diameter portion 123 that is the tip portion is inside the through-hole 121 of the upper collar 20. It is set to a size that can be accommodated. The core member 122 is inserted into the insertion hole 124 formed in the substantially central portion of the elastic body 22 from the through hole 121 of the upper collar 20, and further, a screw formed on the support surface side of the elastic body 22 of the lower collar 21. It is fixed by being screwed into the hole 125. When the core member 122 is inserted from the through hole 121 and fixed to the screw hole 125, the large diameter portion 123 is accommodated in the through hole 121 so that the tip portion is lowered by one step. The core member 122 is fixed to the lower rod 21 so that when the upper rod 20 and the lower rod 21 are about to be displaced relatively in the horizontal direction, the core member 122 is not connected to the tip surface or the through hole of the lifting prevention piece 121a. The displacement of the upper collar 20 is limited by the core member 122 that hits the side surface of the 121 and is fixed to the lower collar 21. That is, the core member 122 functions as a horizontal displacement prevention unit and prevents the upper collar 20 and the lower collar 21 from being excessively displaced in the horizontal direction. Further, the large-diameter portion 123 of the core member 122 is larger than the opening diameter of the lifting prevention piece 121a of the through hole 121 and engages with the lifting prevention piece 121a. When the lifting force is applied to the upper rod 20, the core member 122 is engaged with the upper rod 20 and the lower rod by locking the lifting prevention piece 121 a to the large diameter portion 123 of the core member 122 fixed to the lower rod 21. 21 is prevented from deviating. That is, the large diameter part 123 functions also as a lifting prevention part.

  Further, the support structure 120 is similar to the support structure 1 shown in FIG. 1 in that the guide member 12 is fixed to the side surface portion 20c of the upper collar 20 and the side surface portion 12c is brought into contact with the side surface portion of the upper structure 2. The upper portion 20 is slidably supported in the bridge axis direction with respect to the upper structure 2 by the joint portion 34 being engaged with the upper surface 2 b of the upper structure 2, and the upper portion 20 is supported by the sliding member 11. The upper rod 20 can be guided when sliding in the bridge axis direction, and the upper rod 20 can be prevented from being separated from the upper structure 2. Accordingly, even in such a support structure 120, the support device 10 can be easily attached to the upper structure 2 by the guide member 12 so as to be a movable rubber support device. With the member 12, the support device 10 can be used as a movable rubber support device.

  In the support structure 120, the engaging portion 34 may be provided separately from the main body portion 12 e of the guide member 12, similarly to the support structure 110 shown in FIG. 8.

[10. Description of modification 3 of bearing structure]
In the above example, as shown in FIG. 6, the length in the bridge axis direction (length direction) of the side surface portions 20 c and 20 c of the upper rod 20 is substantially the same as the length of the upper rod 20 in the length direction. One guide member 12 is fixed, but as shown in FIG. 10, in the support structure 130 of the third modification, the length in the length direction is set on the side surface portions 20 c and 20 c of the upper collar 20. A plurality of guide members 12 shorter than the length in the length direction are fixed.

  For example, in the support structure 130, as shown in FIG. 10, the guide member 12 whose length in the length direction is shorter than the length in the length direction of the upper collar 20 is the length of each side surface portion 20 c, 20 c of the upper collar 20. It is fixed at two places on one end and the other end in the vertical direction, and is fixed to a total of four places on both side surfaces 20c, 20c of the upper collar 20. Note that the number and the fixing position of the guide members 12 are not limited to this, and can be appropriately changed depending on the size and weight of the support device 10.

  Even such a guide member 12 is fixed to the side surface portion 20c of the upper collar 20, the side surface portion 12c abuts on the side surface portion of the upper structure 2, and the engaging portion 34 is the upper surface 2b of the upper structure 2. Is engaged with the upper structure 2 so as to be slidable in the bridge axis direction, and when the upper collar 20 is slid by the sliding member 11 in the bridge axis direction, 20 can be guided to prevent the upper collar 20 from being separated from the upper structure 2. Further, such a guide member 12 can be reduced in weight as compared with the length in the length direction of the upper collar 20 as shown in FIG. Can be manufactured.

  Therefore, even in such a support structure 130, the support device 10 can be easily attached to the upper structure 2 by the guide member 12 so as to be a movable rubber support device, and the sliding member 11 and the guide member 12, the bearing device 10 can be used as a movable rubber bearing device.
