Description

[Technical field]

[0001] The present invention relates to a support device used in a support structure that is arranged, for example, between an upper structure and a lower structure and supports the upper structure with the lower structure. [Background technology]

[0002] Conventionally, there have been bearing devices that provide movable support in structures where vibration or relative displacement occurs, such as seismic isolation structures or connection parts that connect fixed structures together. As disclosed in Patent Document 1, these bearing devices are equipped with an upper shoe provided on the upper structure and a lower shoe provided on the lower structure, and are configured so that the sliding surfaces of the upper shoe and the lower shoe slide against each other to provide movable support.

[0003] However, the bearing device disclosed in Patent Document 1 is designed to have a sliding surface area according to the load (stress) borne by one shoe. In other words, each bearing device is designed and manufactured individually according to various conditions such as the load of the superstructure. For this reason, the versatility of the bearing device is low, and it has been difficult to efficiently configure the bearing device. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2007-225016 A Summary of the Invention [Problem to be solved by the invention]

[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a bearing device that is highly versatile and can be constructed efficiently. [Means for solving the problem]

[0006] This invention is a support device which is composed of an upper shoe and a lower shoe which are arranged on the respective mounting surfaces of an upper structure and a lower structure, one of the upper shoe and the lower shoe being provided with a sliding member which forms a sliding surface, and the other of the upper shoe and the lower shoe being provided with a sliding plate material which forms the sliding surface and is wider than the sliding member, and the sliding surfaces of the upper shoe and the lower shoe slide against each other, and is characterized in that one of the upper shoe and the lower shoe is provided with a plurality of sliding members whose sliding surface area is smaller than the sliding surface area for the load borne by the support device, and is also provided with an elastic member which elastically supports the sliding member with respect to the mounting surface of the structure on which the sliding member is provided, and a position regulating member which regulates the relative positions of the plurality of sliding members in the planar direction.

[0007] The above-mentioned superstructure and substructure may be, for example, a building with a building as the superstructure and a foundation structure as the substructure, a bridge with a pier as the substructure and a main girder as the superstructure, a connecting passage with a building as the substructure and a walkway connecting buildings as the superstructure, a roof structure with a column as the substructure and a truss roof as the superstructure, or a structure in an expansion structure with a building as the substructure and another building as the superstructure. Or, it may be a structure with a rack housing servers as the superstructure and a floor on which the rack is placed as the substructure.

[0008] The sliding member having a smaller sliding surface area than the sliding surface area for the load borne by the above-mentioned bearing device means that in a bearing structure equipped with multiple shoes, the load to be shared by each shoe (each bearing device) is set, and multiple sliding members having a smaller sliding surface area (size in the planar direction) than a sliding member having a sliding surface area corresponding to the set load (load) are able to share and bear a load that is greater than the load borne by the shoe (bearing device).

[0009] The elastic member that elastically supports the sliding member against the installation surface may be provided directly between the sliding member and the installation surface, or may be provided via a separate member. Moreover, the term "elastic support" means that the sliding member can be deformed when a load is applied to the sliding member.

[0010] The position restricting member that restricts the relative positions of the plurality of sliding members in the planar direction may be an integrated position restricting member as long as each of the plurality of sliding members is restricted to be movable in the opposing direction, i.e., in the vertical direction, or may be configured to restrict the positions of the holding members in the planar direction by connecting the holding members to each other with holding members that hold each of the sliding members to be movable in the vertical direction. Note that the position restricting member and the elastic member may be a single member having both functions, or may be separate members having each function.

[0011] According to the present invention, versatility is improved and the support device can be efficiently configured. More specifically, one of the upper shoe and the lower shoe in the bearing device disposed on the respective mounting surfaces of the upper structure and the lower structure is provided with a plurality of sliding members whose sliding surface area is smaller than the sliding surface area for the load borne by the bearing device. Therefore, the shoe can be constructed by combining an appropriate number of the sliding members whose sliding surface area is smaller according to the load borne by the bearing device.

[0012] Therefore, without having to design and manufacture shoes according to various conditions such as the load of the superstructure, it is possible to use the sliding members, each having a sliding surface area smaller than the sliding surface area for the load borne by the bearing device, in a number corresponding to the load to be shared, thereby improving versatility and enabling the bearing device to be constructed efficiently.

[0013] However, since the shoe is made up of multiple sliding members whose sliding surface area is smaller than the sliding surface area for the load borne by the bearing device, if the sliding surfaces of the multiple small sliding members are not uniform, that is, steps may occur, due to manufacturing tolerances and assembly accuracy. If the sliding surfaces of the multiple small sliding members are not of uniform height, that is, steps occur, the sliding performance of the bearing device will decrease.

[0014] In contrast, an elastic member is provided that elastically supports the sliding member against the installation surface of the structure on which the sliding member is provided, so that the sliding member that is taller (longer distance from the installation surface of the upper structure or lower structure) becomes of a uniform height with the sliding surfaces of the other smaller sliding members as the elastic member deforms, thereby eliminating any steps and ensuring the desired sliding performance.

[0015] Even if the sliding surfaces of the multiple small sliding members are at a uniform height, if the arrangement of the multiple small sliding members, i.e., the relative positions in the planar direction, are shifted, the sliding performance of the support device will still decrease. In contrast, the position regulating member regulates the relative positions of the multiple sliding members in the planar direction, so that the desired sliding performance can be ensured.

[0016] In this way, one of the upper and lower shoes in the bearing device arranged on the respective mounting surfaces of the upper structure and the lower structure is provided with a plurality of sliding members whose sliding surface area is smaller than the sliding surface area for the load borne by the bearing device, an elastic member that elastically supports the sliding members against the mounting surface of the structure on which the sliding members are provided, and a position regulating member that regulates the relative positions of the plurality of sliding members in the planar direction.This makes it possible to efficiently construct a bearing device that ensures the desired sliding performance and has improved versatility.

[0017] As an aspect of the present invention, the elastic member may be formed across at least two of the sliding members. According to this invention, since the elastic member is formed across at least two of the sliding members, the sliding members formed across the elastic member have a height higher than that of the other sliding member, and when the elastic member is deformed so that the height of one of the sliding members becomes lower, the influence of the deformation acts to increase the height of the other sliding member. Therefore, by forming the elastic member across at least two of the sliding members, the amount of deformation required to make the heights of one sliding member and the other sliding member uniform can be reduced.

[0018] In another aspect of the present invention, the elastic member may be formed across all of the sliding members, and the position regulating member may be provided with a concave mounting recess into which the sliding member can be mounted, and the position regulating member and the elastic member may be integrally formed from an elastic material.

[0019] According to this invention, by simply arranging the sliding members in the mounting recesses, the relative positions of the sliding members in the planar direction can be regulated and elastic support can be provided, thereby improving the ease of assembly of the shoe composed of the multiple small sliding members and the support device having the shoe.

[0020] In addition, since the elastic member is formed across all of the sliding members, the effect of deformation of the elastic member, which reduces the height of a sliding member that is taller than the other sliding members, acts on the other sliding members, and the amount of deformation required for the tall sliding member to become uniform in height with the other sliding members can be reduced.

[0021] As a further aspect of the present invention, a holder for holding the sliding member may be provided, and the position restriction member may be provided with a recessed mounting recess into which the holder can be inserted. The holder for holding the sliding member may have the sliding member adhered to the surface of the holder, or the sliding member may be fitted into a recess provided in the holder.

[0022] According to this invention, a shoe can be formed from a plurality of small sliding members firmly held by the holder, and a support device having stable sliding performance can be formed.

[0023] As a further aspect of the present invention, a holder may be provided for holding the sliding member, and the elastic member may be disposed between the holder and the sliding member in a deformable manner. According to this invention, the holder can be firmly fixed directly or indirectly to the mounting surface of the structure, and the height of the sliding member can be adjusted with respect to the holder fixed to the mounting surface of the structure by an elastic member.

[0024] As a further aspect of the present invention, the elastic member may have a deformable space on the inside in a plan view, and may be formed in a circumferential shape so as to surround the space. According to this invention, when the elastic member deforms to lower the height of the sliding member, if there is no deformation space for the elastic member, the elastic member cannot deform, and the height of the sliding member relative to the holder cannot be adjusted. In contrast, the elastic member formed in a circumferential shape has a deformable space on the inside in a plan view, so that the sliding member can deform to lower the height without changing the deformation performance of the sliding member. Effect of the Invention

[0025] According to the present invention, it is possible to provide a bearing device that is highly versatile and can be efficiently constructed. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] An embodiment of the present invention will now be described with reference to the drawings. FIG. 1 shows an explanatory diagram of a support structure 1, FIG. 2 shows an explanatory diagram of a module support device 10, and FIG.

[0028] More specifically, Fig. 1(a) shows a schematic diagram of the support structure 1 from the front direction. Note that Fig. 1(a) shows the right side of the support structure 1 in the left-right direction in a front view and the left side in a cross-sectional view, and Fig. 1(b) shows a bottom view of the module upper shoe 30. Fig. 1 also shows an enlarged view of part a in Fig. 1(a).

[0029] Fig. 2(a) shows an exploded perspective view from the top side of the module support device 10, Fig. 2(b) shows a perspective view from the bottom side of the module upper shoe 30, and Fig. 2(c) shows an exploded perspective view from the bottom side of the module upper shoe 30. Note that the base plate 31 of the module upper shoe 30 is omitted in Figs. 2(b) and 2(c). Also, a portion of the front side of the elastic retaining member 32 in Figs. 2(a) and 2(c) is cut away, and in Fig. 2(a), one bearing unit 50 hidden by the elastic retaining member 32 is shown by a dashed line.

[0030] Fig. 3(a) shows a schematic cross-sectional view of the support structure 1 before the upper structure 100 is supported by the lower structure 110, i.e., before the module support device 10 is assembled, and Fig. 3(b) shows a schematic cross-sectional view of the support structure 1 after the upper structure 100 is supported by the lower structure 110, i.e., after the module support device 10 is assembled. Fig. 3 shows an enlarged view of part b in Fig. 3(a).

[0031] The support structure 1 has a module support device 10 consisting of a lower shoe 20 and a module upper shoe 30, a lower structure 110 having the lower shoe 20 provided on its upper surface 111, and an upper structure 100 having the module upper shoe 30 provided on its bottom surface 101, and is a structure in which the upper structure 100 is supported by the lower structure 110 via the module support device 10.

[0032] The module bearing device 10 is an elastic sliding bearing device that allows sliding in all directions when viewed from a plan view, and is also called an omnidirectional sliding bearing device. The module bearing devices 10 are installed between the upper structure 100 and the lower structure 110, with the number of module bearing devices 10 depending on the load of the upper structure 100. The module bearing devices 10 may also be installed together with rubber bearings, etc.

[0033] The module support device 10 includes a module upper shoe 30 that is fixed to the bottom surface 101 of the upper structure 100 , and a module lower shoe 20 that is fixed to the top surface 111 of the lower structure 110 . The lower shoe 20 comprises a sole plate 21 fixed to the upper surface 111 of the lower structure 110 and a slide plate 22 attached to the upper surface of the sole plate 21.

[0034] The sole plate 21 is formed in a disk shape having a circular shape in plan view and a predetermined thickness, and is configured to be fixed to the upper surface 111 of the lower structure 110 by an appropriate method. The slide plate 22 is configured from a circular stainless steel plate with a slightly smaller diameter than the sole plate 21, and the upper surface of the slide plate 22 forms a sliding surface that slides against the sliding surface of the module upper shoe 30.

[0035] As shown in Figure 3, the module upper shoe 30 comprises a disk-shaped base plate 31 which is circular in plan view and has a predetermined thickness and is approximately the same diameter as the sole plate 21, an elastic retaining member 32 arranged on the bottom side of the base plate 31, and a plurality of bearing units 50 attached to the elastic retaining member 32. The disk-shaped base plate 31, which is circular in plan view, has approximately the same diameter as the sole plate 21, and has a predetermined thickness, is configured to be fixed to the bottom surface 101 of the upper structure 100 by an appropriate method.

[0036] The elastic holding member 32 disposed on the bottom side of the base plate 31 is formed in a disk shape having a predetermined thickness and a smaller diameter than the base plate 31. The elastic holding member 32 is made of rubber having a predetermined elasticity, and has a plurality of mounting recesses 33 that open on the bottom side.

[0037] Since the module upper shoe 30 of this embodiment is equipped with three bearing units 50 described later, the three mounting recesses 33 are arranged to form an equilateral triangle when viewed from the bottom. The mounting recesses 33 are formed to a depth of about half the thickness of the elastic holding member 32 formed to a predetermined thickness, and are formed to have approximately the same diameter as a cylindrical portion 54 of the bearing unit 50 described later.

[0038] The elastic retaining member 32 configured in this manner functions as an elastic support member that elastically supports the bearing unit 50 described below, which is mounted in the mounting recess 33, relative to the upper structure 100 via the base plate 31, and also functions as a position control member that controls the relative positions of the multiple bearing units 50 in the planar direction.

[0039] The bearing unit 50 is composed of a bearing 51 which is circular when viewed from the bottom, and a holder 52 which holds the bearing 51 . The bearing 51, which is a sliding member, is made of polyamide resin or polytetrafluoroethylene resin having self-lubricating properties and has a circular shape in a plan view. The bottom surface of the bearing 51 constitutes a sliding surface that slides against the sliding surface that is the upper surface of the slide plate 22 of the lower shoe 20.

[0040] The planar size (area) of the bearing 51 is formed to have a diameter that provides a small area relative to the load (weight) borne by the module support device 10 . Specifically, in the bearing structure 1 in which the upper structure 100 is supported by the lower structure 110 via a plurality of module bearing devices 10, the load borne by each module bearing device 10 is set relative to the load of the upper structure 100. Then, the planar size (area) of the bearing is set relative to the load set for each module bearing device 10. The planar size (area) of the bearing 51 is formed to be smaller (smaller diameter) than the planar size (area) of the bearing set for the load set for each module bearing device 10 as described above.

[0041] More specifically, the planar size (area) of the bearings 51 is formed so that the plurality of bearings 51 can accommodate the load set for each module support device 10 . In this embodiment, a load of 15 kN is set for each module support device 10, and therefore three bearing units 50 are set to bear the load of 15 kN set for each module support device 10. Therefore, the bearings 51 of each bearing unit 50 are formed with a planar size (area) that can share a load of 5 kN, and the planar size (area) becomes smaller when a single bearing bears a load of 15 kN. Note that the load to be set is not limited to the above-mentioned 15 kN, and may be any appropriate load, such as 10 kN, depending on the structure to be installed.

[0042] The holder 52 that holds the bearing 51 has a holder body 53 having a mounting recess 531 provided on the bottom surface, and a cylindrical portion 54 having a smaller diameter than the holder body 53, and is made of metal. The holder body 53 is generally disk-shaped and has a larger diameter than the bearing 51, and is provided with a mounting recess 531 on the bottom surface for mounting the bearing 51. The mounting recess 531 is a circular recess in bottom view that is formed with a depth shallower than the thickness of the bearing 51.

[0043] The cylindrical portion 54 is cylindrical and protrudes upward from the holder body 53 , has a smaller diameter than the holder body 53 , and is formed with approximately the same height as the depth of the mounting recess 33 of the elastic holding member 32 . The bearing unit 50 configured in this manner is assembled by mounting the bearing 51 in the mounting recess 531 provided in the holder body 53 of the holder 52, but it is also possible to not provide the mounting recess 531 and instead adhesively fix the bearing 51 to the bottom surface of the holder body 53.

[0044] The bearing units 50 configured in this manner are mounted in the mounting recesses 33 of the elastic holding member 32, respectively, to form the module upper shoe 30. Specifically, it can be configured by inserting and fixing a holder main body 53 provided on a holder 52 of the bearing unit 50 into the mounting recess 33 of the elastic holding member 32.

[0045] As shown in Figure 3(a), the sole plate 21 of the lower shoe 20 configured as described above is fixed to the upper surface 111 of the lower structure 110, and the lower shoe 20 is attached to the upper surface 111 of the lower structure 110, and the base plate 31 of the module upper shoe 30 is fixed to the bottom surface 101 of the upper structure 100, and the module upper shoe 30 is attached to the bottom surface 101 of the upper structure 100.

[0046] Then, as shown in Figure 3(b), the assembly of the module support device 10 is completed by slidably opposing the upper surface of the slide plate 22 that forms the sliding surface of the lower shoe 20 attached to the upper surface 111 of the lower structure 110 and the bottom surface of the bearing 51 that forms the sliding surface of the module upper shoe 30 attached to the bottom surface 101 of the upper structure 100, and the support structure 1 that supports the upper structure 100 with the lower structure 110 via the module support device 10 is completed.

[0047] In addition, there are cases where any one of the three bearing units 50 attached to the elastic retaining member 32 in the module upper shoe 30 is higher than the other bearing units 50, that is, as shown in the enlarged view of part b in Fig. 3(a) , the bottom surface of the bearing 51 of one of the bearing units 50 may protrude downward from the bottom surfaces of the bearings 51 of the other bearing units 50. Even in such a case, when the load of the upper structure 100 is applied, as shown by the upward arrow in Fig. 3(b) , the elastic retaining member 32 of the bearing unit 50 whose bottom surface of the bearing 51 protrudes downward from the bottom surfaces of the bearings 51 of the other bearing units 50 is compressed and deformed, so that the bearing unit 50 becomes the same height as the bearings 51 of the other bearing units 50.

[0048] Note that the effect of compressive deformation of the elastic retaining member 32 caused by a bearing unit 50 in which the bottom surface of the bearing 51 protrudes downward due to the bottom surface of the bearing 51 of another bearing unit 50 acts on the portion in which the other bearing unit 50 is mounted, i.e., the periphery of the mounting recess 33 in which the other bearing unit 50 is mounted, and deforms so as to push the other bearing unit 50 downward as shown by the downward arrow in Figure 3(b). Therefore, the amount of deformation can be made smaller than that caused by compressive deformation caused by a bearing unit 50 in which the bottom surface of the bearing 51 protrudes.

[0049] The module support device 10 thus configured is composed of a module upper shoe 30 disposed on the bottom surface 101 of the upper structure 100 and a lower shoe 20 disposed on the top surface 111 of the lower structure 110, the module upper shoe 30 is provided with a bearing 51 constituting a sliding surface, the lower shoe 20 is provided with a slide plate 22 constituting the sliding surface and being wider than the bearing 51, and the sliding surfaces of the module upper shoe 30 and the lower shoe 20 slide against each other. The module upper shoe 30 is provided with a plurality of bearings 51 whose sliding surface area is smaller than the sliding surface area for the load borne by the module support device 10, and the module upper shoe 30 is provided with an elastic retaining member 32 that elastically supports the bearings 51 in the opposing direction (up and down direction) with respect to the bottom surface 101 of the upper structure 100 and regulates the relative positions of the plurality of bearings 51 in the planar direction.

[0050] This improves versatility and enables the module support device 10 to be configured efficiently. More specifically, the module upper shoe 30 is provided with a plurality of bearings 51 whose sliding surface area is smaller than the sliding surface area for the load borne by the module support device 10. Therefore, the module upper shoe 30 can be configured by combining an appropriate number of bearings 51 whose sliding surface area is smaller than the sliding surface area for the load borne by the module support device 10. Therefore, without designing and manufacturing upper shoe bearings according to various conditions such as the load of the superstructure 100, it is possible to use the bearings 51 whose sliding surface area is smaller than the sliding surface area for the load borne by the module support device 10 in a number corresponding to the shared load, improving versatility and enabling the module support device 10 to be configured efficiently.

[0051] However, since the module upper shoe 30 is made up of multiple bearings 51 whose sliding surface area is smaller than the sliding surface area for the load borne by the module support device 10, there is a risk that the sliding surfaces of the multiple small bearings 51 will not be uniform, that is, steps will occur, due to manufacturing tolerances and assembly accuracy. If the sliding surfaces of the multiple small bearings 51 are not of uniform height, that is, if steps occur, the sliding performance of the module support device 10 will decrease.

[0052] In response to this, an elastic retaining member 32 that elastically supports the bearing 51 in the opposing direction (up and down direction) is provided to the bottom surface 101 of the upper structure 100 on which the module upper shoe 30 having the bearing 51 is provided. Therefore, the bearing 51 that is taller than the other bearings 51 (its distance from the bottom surface 101 of the upper structure 100 is long and its bottom surface protrudes downward) becomes at a uniform height with the sliding surfaces of the other bearings 51 by deformation of the elastic retaining member 32, in other words, the step is eliminated, and the desired sliding performance can be ensured.

[0053] Even if the sliding surfaces of the multiple bearings 51 are at a uniform height, any deviation in the arrangement of the multiple bearings 51, i.e., in the planar relative positions, will still reduce the sliding performance of the module bearing device 10. In response to this, the elastic retaining member 32 regulates the relative positions of the multiple bearings 51 in the planar direction, ensuring the desired sliding performance.

[0054] In this way, the module upper shoe 30 is provided with a plurality of bearings 51 whose sliding surface area is smaller than the sliding surface area for the load borne by the module support device 10, an elastic retaining member 32 that elastically supports the bearings 51 in the opposing direction (up and down direction) relative to the bottom surface 101 of the upper structure 100 on which the bearings 51 are provided, and an elastic retaining member 32 that regulates the relative positions of the plurality of bearings 51 in the planar direction, thereby ensuring the desired sliding performance and efficiently configuring a module support device 10 with improved versatility.

[0055] In addition, because the elastic retaining member 32 is formed across all of the bearings 51, when the elastic retaining member 32 deforms so that one bearing 51 that is taller than the other bearings 51 becomes shorter, the influence of the deformation acts to increase the height of the other bearings 51. Therefore, by forming the elastic retaining member 32 across at least two bearings 51, the amount of deformation required to make the heights of one bearing 51 and the other bearings 51 uniform can be reduced.

[0056] In addition, since the elastic retaining member 32, which is formed over all of the bearings 51 and has the concave mounting recesses 33 into which the bearings 51 can be mounted, is made of rubber, the relative positions of the multiple bearings 51 in the planar direction can be regulated and the multiple bearings 51 can be elastically supported simply by placing the bearings 51 in the mounting recesses 33. Therefore, the ease of assembly of the module upper shoe 30 composed of the multiple bearings 51 and the module support device 10 having the module upper shoe 30 can be improved.

[0057] In addition, since the elastic retaining member 32 is formed over all of the bearings 51, the effect of deformation of the elastic retaining member 32, which reduces the height of the tall bearing 51 relative to the other bearings 51, acts on the other bearings 51, and the amount of deformation required for the tall bearing 51 to become uniform in height with the other bearings 51 can be reduced.

[0058] In addition, a holder 52 is provided to hold the bearings 51, and the elastic holding member 32 is provided with a concave mounting recess 33 into which the holder 52 can be inserted, so that the module upper shoe 30 can be formed from a plurality of bearings 51 firmly held by the holder 52, and a module support device 10 with stable sliding performance can be formed.

[0059] As described above, in the configuration of the present invention and the correspondence with the above-mentioned embodiment, the upper structure of the present invention corresponds to the upper structure 100, Similarly, The lower structure corresponds to the lower structure 110; The installation surface corresponds to the bottom surface 101, The upper shoe corresponds to the module upper shoe 30, The lower shoe corresponds to the lower shoe 20, The sliding member corresponds to the bearing 51, The sliding plate corresponds to the slide plate 22, The bearing device corresponds to a modular bearing device 10, The elastic member and the position restriction member correspond to the elastic holding member 32, The mounting recess corresponds to the mounting recess 33, The holder corresponds to the holder 52, but is not limited to the above embodiment.

[0060] For example, the above-mentioned superstructure 100 and substructure 110 may be structures in a building in which the superstructure 100 is a building and the substructure 110 is a foundation structure, a bridge in which the substructure 110 is a bridge pier and the superstructure 100 is a main girder, a connecting passage in which the substructure 110 is a building and the superstructure 100 is a walkway connecting buildings, a roof structure in which the substructure 110 is a column and the superstructure 100 is a truss roof, or an expansion structure in which a building is the substructure 110 and another building is the superstructure 100. Alternatively, the structure may be a rack that stores servers is the superstructure 100 and the floor on which the rack is placed is the substructure 110.

[0061] For example, the module upper shoe 30 of the above-mentioned module support device 10 has three bearing units 50, each having a bearing 51, arranged in an equilateral triangle with respect to the elastic retaining member 32, but the number and arrangement of the bearing units 50 are not limited. For example, as shown in Fig. 4, the module upper shoe 30 may be configured by arranging an appropriate number of bearing units 50 in an appropriate shape.

[0062] 4A and 4B show explanatory diagrams of bottom views of the module upper shoe 30 of another embodiment. In detail, FIG. 4A shows a bottom view of the module upper shoe 30 equipped with six bearing units 50, and FIG. 4B shows a bottom view of the module upper shoe 30 equipped with nine bearing units 50.

[0063] Specifically, for example, the modular upper shoe 30 may include six bearing units 50. The modular upper shoe 30 includes six bearing units 50, and three bearing units 50 are disposed at the vertices of an equilateral triangle, with a bearing unit 50 disposed at each midpoint of each side of the equilateral triangle.

[0064] Also, for example, the modular shoe 30 may include nine bearing units 50. The modular shoe 30 including nine bearing units 50 has four bearing units 50 arranged at the vertices of a square, and a bearing unit 50 is arranged at each of the midpoints of each side of the square and in the center when viewed from the bottom.

[0065] In this way, the module upper shoe 30 equipped with multiple bearing units 50 can be constructed by dividing the load borne by the module bearing device 10 into an appropriate number and arranging that number of bearing units 50 at the vertices of a regular polygon, the center of the regular polygon, or the middle of the sides. Alternatively, the module upper shoe 30 may have multiple bearing units 50 arranged concentrically. In this case, it is preferable to arrange the bearing units 50 so that they are spaced equally apart.

[0066] In addition, in the module upper shoe 30 of the above-mentioned module support device 10, the bearing units 50 are mounted in the mounting recesses 33 of the elastic retaining member 32, and the multiple bearing units 50 are elastically supported while regulating their relative positions. In other words, the elastic retaining member 32 of the module upper shoe 30, in which the bearing units 50 are mounted in the multiple mounting recesses 33, functions as an elastic support member and also as a relative position regulating member.

[0067] 5, the module upper shoe 30a may be configured by making the retaining member 32a function only as a relative position regulating member and providing a ring rubber 34 functioning as an elastic support member. In the following description of the module upper shoe 30a, the same components as those in the above-mentioned module upper shoe 30 are denoted by the same reference numerals and description thereof will be omitted.

[0068] In the case of the module upper shoe 30a in which the holding member 32a functions only as a relative position regulating member, the holding member 32a has the same shape as the above-mentioned elastic holding member 32, but is made of resin or metal. A cylindrical portion 54a of a holder 52a in a bearing unit 50a to be mounted in the mounting recess 33 is formed lower than the cylindrical portion 54 of the bearing unit 50 described above.

[0069] When the bearing unit 50 a is mounted in the mounting recess 33 , the ring rubber 34 is interposed between the cylindrical portion 54 a and the bottom surface of the mounting recess 33 . The ring rubber 34 is ring-shaped with an outer diameter substantially equal to that of the mounting recess 33 and a circular deformation allowance space 341 in the center when viewed from above, that is, it is circumferential so as to surround the deformation allowance space 341, and is made of rubber having suitable elasticity. The ring rubber 34, together with the cylindrical portion 54a, is formed to have a height substantially equal to the depth of the mounting recess 33.

[0070] The bearing unit 50a, which is mounted in the mounting recess 33 with the thus configured ring rubber 34 interposed between the ring rubber 34 and the bottom surface of the mounting recess 33, is mounted in the mounting recess 33 so as to be slidable in the up and down direction (mounting direction).

[0071] The thus configured module support device 10 having a module upper shoe 30a with a ring rubber 34 and the support structure 1 supporting the upper structure 100 with the lower structure 110 via the module support device 10 can achieve the same effects as the above-mentioned module support device 10 having the module upper shoe 30 and the support structure 1 supporting the upper structure 100 with the lower structure 110 via the module support device 10.

[0072] Further, the ring rubber 34 has a deformation allowance space 341 on the inside in a plan view, and is formed in a circumferential shape so as to surround the deformation allowance space 341 . When the ring rubber 34 deforms so that the height of the bearing 51 becomes lower relative to the mounting recess 33, if there is no space between the holder 52 and the mounting recess 33 in which the ring rubber 34 can deform, the ring rubber 34 cannot deform and the height of the bearing 51 cannot be adjusted relative to the holder 52. In contrast, the ring rubber 34 has a deformation allowance space 341 and is formed in a circumferential shape so as to surround the deformation allowance space 341, so that the ring rubber 34 can deform so that the height of the bearing 51 becomes lower relative to the elastic retaining member 32 without changing the deformation performance of the bearing 51 relative to the elastic retaining member 32.

[0073] In the above description, a ring rubber 34 is provided between the bottom surface of the mounting recess 33 and the holder 52, but a ring rubber 34 may also be provided between the bottom surface of the mounting recess 531 and the bearing 51 in the holder 52 that holds the bearing 51. In this case, the holder 52 is firmly fixed to the bottom surface 101 of the upper structure 100 via the base plate 31 and the elastic retaining member 32, and the height of the bearing 51 relative to the holder 52 fixed to the bottom surface 101 of the upper structure 100 can be adjusted by the ring rubber 34.

[0074] In the above embodiment, the outer circumferential shapes of the mounting recess 33, the bearing units 50, 50a, the bearing 51, etc. are circular, but the shape is not limited to a circle and may be, for example, a polygonal shape. In this case, the shape of the ring rubber 34 may be a shape that matches the outer circumferential shapes of the mounting recess 33, the bearing units 50, 50a, the bearing 51, etc.

[0075] In the above description, the module support device 10 is configured by attaching the lower shoe 20 having the sole plate 21 and the slide plate 22 to the upper surface 111 of the lower structure 110, and attaching the module upper shoes 30, 30a having multiple bearing units 50, 50a to the bottom surface 101 of the upper structure 100. Alternatively, the module support device 10 may be configured by attaching an upper shoe having a sole plate and a slide plate to the bottom surface 101 of the upper structure 100, and attaching a module lower shoe having multiple bearing units 50, 50a to the upper surface 111 of the lower structure 110, and in this case too, the same effects as those of the module support device 10 described above can be achieved.
