DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] (First embodiment) Hereinafter, a spherical sliding bearing according to one embodiment of the present disclosure will be described with reference to the drawings. A plurality of spherical sliding bearings according to this embodiment are provided in large structures such as buildings, warehouses, bridges, and the like. In such a building, it is required to be able to identify each of the multiple spherical sliding bearings and to manage various information corresponding to each of the identified spherical sliding bearings without mix-up or tampering. The various information is, for example, information on the results of inspections on materials, dimensions, paint, and product performance performed on each configuration of the multiple spherical sliding bearings. Product performance refers to, for example, the hysteresis characteristics of the horizontal load and horizontal displacement in the spherical sliding bearing. Product performance may include, for example, the friction coefficient of the spherical sliding bearing. In order to respond to the above, the spherical sliding device according to this embodiment is capable of identifying each of the multiple spherical sliding bearings. In addition, the various information corresponding to each of the spherical sliding bearings is stored in a viewable state in a folder created for each building on a server on the cloud (details will be described later).

[0010] (Spherical sliding bearing) FIG. 1 is a side view of a spherical sliding bearing 100 according to an embodiment. FIG. 2 is a first example of a plan view of the spherical sliding bearing 100 according to the embodiment. FIG. 3 is a second example of a plan view of the spherical sliding bearing 100 according to the embodiment. As shown in Figs. 1, 2 and 3, the spherical sliding bearing 100 includes an upper shoe 10, a lower shoe 20, a sliding member 30 and an identification means 40. The spherical sliding bearing 100 is disposed between the upper structure U and the lower structure B. The upper shoe 10 and the lower shoe 20 slide on the sliding member 30, respectively. This allows the upper shoe 10 and the lower shoe 20 to move relative to each other in the horizontal direction. As a result, the spherical sliding bearing 100 suppresses the propagation of ground vibrations caused by earthquakes to the building. The spherical sliding bearing 100 according to this embodiment is a so-called double pendulum type spherical sliding bearing that includes the above-mentioned configurations. In this embodiment, the upper structure U is, for example, a building, and the lower structure B is, for example, a foundation structure of the building formed on the ground.

[0011] (upper shoe) The upper shoe 10 is a portion of the spherical sliding bearing 100 that is connected to the lower portion of the upper structure U. The upper shoe 10 is, for example, a plate-like member that is rectangular or square in plan view. Hereinafter, the upper surface, lower surface, and side surface of the upper shoe 10 are referred to as the upper shoe upper surface 11, the upper shoe lower surface 12, and the upper shoe side surface 13, respectively. The upper shoe upper surface 11 faces the upper structure U. The upper shoe upper surface 11 and the upper structure U are fixed together by, for example, welding, bolt fastening, or the like. The upper shoe lower surface 12 faces the lower structure B. An upper shoe sliding surface 12s is provided on the upper shoe lower surface 12. The upper shoe sliding surface 12s is a recess provided on the upper shoe lower surface 12. As shown in FIG. 1, for example, the upper shoe sliding surface 12s has an arc-shaped (spherical) cross section. As shown in FIG. 2 or FIG. 3, the upper shoe sliding surface 12s is formed in a circular shape in a plan view. The upper shoe sliding surface 12s slides against the sliding member 30. This allows the upper shoe 10 and the sliding member 30 to move relative to each other in the horizontal direction. At this time, in order to prevent the sliding member 30 from coming off the upper shoe sliding surface 12s when the upper shoe 10 and the sliding member 30 slide against each other, it is preferable that a stopper ring S is provided on the edge of the upper shoe sliding surface 12s in a plan view. The stopper ring S may be formed integrally with the upper shoe 10, for example, by forming a wall portion 12w against which the sliding member 30 can abut between the upper shoe lower surface 12 and the upper shoe sliding surface 12s. Alternatively, the stopper ring S may be formed by attaching, for example, an annular member to the upper shoe lower surface 12. The upper shoe side surface 13 connects the upper shoe upper surface 11 and the upper shoe lower surface 12. The upper shoe side surface 13 faces in the horizontal direction.

[0012] (lower shoe) The lower shoe 20 is configured to be paired with the upper shoe 10. That is, in this embodiment, the lower shoe 20 is formed symmetrically with the upper shoe 10. The lower shoe 20 is a portion of the spherical sliding bearing 100 that is connected to the upper portion of the lower structure B. The lower shoe 20 is, for example, a plate-like member that is rectangular or square in plan view. Hereinafter, the upper surface, lower surface, and side surface of the lower shoe 20 are referred to as the lower shoe upper surface 21, the lower shoe lower surface 22, and the lower shoe side surface 23, respectively. The lower shoe upper surface 21 faces the upper structure U. A lower shoe sliding surface 21s is provided on the lower shoe upper surface 21. The lower shoe sliding surface 21s is a recess provided on the lower shoe upper surface 21. The lower shoe sliding surface 21s has an arc-shaped (spherical) cross section as shown in FIG. 1, for example. The lower shoe sliding surface 21s is formed in a circular shape in a plan view as shown in FIG. 2 or FIG. 3. The lower shoe sliding surface 21s slides against the sliding member 30. This allows the lower shoe 20 and the sliding member 30 to move relative to each other in the horizontal direction. At this time, in order to prevent the sliding member 30 from coming off the lower shoe sliding surface 21s when the lower shoe 20 and the sliding member 30 slide against each other, it is preferable that a stopper ring S is provided on the edge of the lower shoe sliding surface 21s in a plan view. The stopper ring S may be formed integrally with the lower shoe 20, for example, by forming a wall portion 21w against which the sliding member 30 can abut between the lower shoe upper surface 21 and the lower shoe sliding surface 21s. Alternatively, the stopper ring S may be formed by attaching, for example, an annular member to the lower shoe upper surface 21. The lower shoe lower surface 22 faces the lower structure B. The lower shoe lower surface 22 and the lower structure B are fixed together by, for example, welding or bolting. The lower shoe side surface 23 connects the lower shoe upper surface 21 and the lower shoe lower surface 22. The lower shoe side surface 23 faces in the horizontal direction.

[0013] The upper shoe 10 and the lower shoe 20 are arranged so that their four sides overlap in a plan view, as shown in Fig. 2. Alternatively, the upper shoe 10 and the lower shoe 20 may be arranged so that their four sides do not overlap in a plan view, as shown in Fig. 3.

[0014] (Sliding member) The sliding member 30 is provided between the upper shoe 10 and the lower shoe 20. The sliding member 30 slides between the upper shoe 10 and the lower shoe 20. The sliding member 30 is, for example, a circular member in a plan view. More specifically, the sliding member 30 is a substantially cylindrical member and is disposed so that its axis is along the vertical direction. The sliding member 30 includes an upper sliding surface 31 facing upward, a lower sliding surface 32 facing downward, and a sliding portion side surface 33 connecting the upper sliding surface 31 and the lower sliding surface 32. The upper sliding surface 31 slides against the upper shoe 10. More specifically, the upper sliding surface 31 slides against the upper shoe sliding surface 12s of the upper shoe 10. This allows the upper shoe 10 and the sliding member 30 to move relatively in the horizontal direction. The lower sliding surface 32 slides against the lower shoe 20. More specifically, the lower sliding surface 32 slides against the lower shoe sliding surface 21s of the lower shoe 20. This allows the lower shoe 20 and the sliding member 30 to move relatively in the horizontal direction. This allows the upper shoe 10 and the lower shoe 20 to move relatively in the horizontal direction. The sliding portion side surface 33 is located in an annular shape between the upper sliding surface 31 and the lower sliding surface 32. The sliding portion side surface 33 faces in the horizontal direction.

[0015] (Identification means) FIG. 4 is a first diagram showing an example of mounting the identification means 40 to the spherical sliding bearing 100. As shown in FIG. FIG. 5 is a second diagram showing an example of mounting the identification means 40 to the spherical sliding bearing 100. As shown in FIG. The identification means 40 is provided to enable identification of the spherical sliding bearing 100. In other words, the identification means 40 is provided to enable identification of each of the spherical sliding bearings 100 provided in a building. Alternatively, the identification means 40 may be capable of individually identifying any of the components of the spherical sliding bearing 100. In other words, the identification means 40 may be capable of individually identifying each of the components of the spherical sliding bearing 100, particularly the upper shoe 10, the lower shoe 20, and the sliding member 30. Identification means, for example, distinguishing one of the multiple spherical sliding bearings 100 from the other spherical sliding bearings 100.

[0016] The identification means 40 may be provided, for example, in two separate means for identifying each individual spherical sliding bearing 100 and for individually identifying each component of the spherical sliding bearing 100, or a single identification means 40 may be capable of identifying both each individual spherical sliding bearing 100 and each component of the spherical sliding bearing 100.

[0017] (Type of identification means) The identification means 40 is preferably, for example, a barcode, a two-dimensional code (a so-called QR code (registered trademark)), an RFID tag, an IC tag, or the like. Alternatively, the identification means 40 may be a character string such as a serial number. Any other identification means may be used as long as it can be read by the reading means 210 (described later).

[0018] The identification means 40 includes, for example, information regarding the address of a server 220 (described later). That is, by reading the identification means 40 with the reading means 210, it becomes possible to access a link destination to the server 220 in which data regarding various information is stored. Alternatively, the identification means 40 itself may indicate the various pieces of information. In other words, it may be possible to refer to the various pieces of information by reading the identification means 40.

[0019] (Method of Installing Identification Means 40) The identification means 40 is provided on the spherical sliding bearing 100 by any of the following methods. The identification means 40 may be provided integrally with at least one of the upper shoe 10, the lower shoe 20, and the sliding member 30 of the spherical sliding bearing 100, or may be provided separately from these and subsequently attached.

[0020] When the identification means 40 is any one of a barcode, a QR code (registered trademark), or a character string, the identification means 40 is provided to the spherical sliding bearing 100 by attaching a sticker on which any one of these is printed. Alternatively, the identification means 40 consisting of any one of these may be provided to any one of the components of the spherical sliding bearing 100 by printing, engraving, or the like. When the identification means 40 is attached to the upper shoe 10 or the lower shoe 20 in the above-mentioned manner, the identification means 40 is attached, for example, after a painting process and before packaging in the manufacturing process of the upper shoe 10 or the lower shoe 20. When the identification means 40 is attached to the sliding member 30 in the above-mentioned manner, the identification means 40 is preferably attached, for example, before a performance test. This makes it possible to store the results of the performance test of the sliding member 30 in association with the identification means 40 corresponding to each individual sliding member 30.

[0021] When the identification means 40 is an RFID tag, the identification means 40 is provided on the spherical sliding bearing 100 by attaching the RFID tag with an adhesive, a sticker, or the like. Alternatively, the identification means 40 may be provided by manufacturing any of the components of the spherical sliding bearing 100 with an RFID tag built in. When the identification means 40 is an RFID tag, it is preferable that a visible mark is provided at the location where the spherical sliding bearing 100 is provided.

[0022] The identification means 40 in this embodiment includes a tamper-proof seal 41. That is, when a seal is used to provide the identification means 40 to the spherical sliding bearing 100, it is preferable to use the tamper-proof seal 41. That is, it is preferable to use a seal that cannot be reattached and that indicates that it has been used once it is removed. The indication that it has been used may be, for example, that at least a part of the tamper-proof seal 41 remains on the spherical sliding bearing 100 even after the seal is removed. This makes it possible to visually confirm that the identification means 40 attached in the manufacturing process is removed and that another identification means 40 is not attached. This makes it possible to prevent tampering by replacing the identification means 40 with another object, etc.

[0023] (Location of identification means) In this embodiment, the identification means 40 is provided in any of the following locations in the spherical sliding bearing 100. That is, in one spherical sliding bearing 100, the identification means 40 may be provided in only one or two of the upper shoe 10, the lower shoe 20, and the sliding member 30, or may be provided in all of them. Only one identification means 40 may be provided in the spherical sliding bearing 100, or multiple identification means 40 may be provided.

[0024] When the identification means 40 is provided on the upper shoe 10, the identification means 40 is provided, for example, on the upper shoe side surface 13. Here, as described above, when the upper shoe 10 is square or rectangular in plan view, four planar upper shoe side surfaces 13 are formed. In this case, the identification means 40 may be provided on only one to three of the four upper shoe side surfaces 13, or on all four. The upper shoe 10 is not limited to a rectangular shape in plan view, and may be a hexagonal or octagonal shape. Alternatively, the identification means 40 may be provided on the upper shoe lower surface 12 of the upper shoe 10 excluding the upper shoe sliding surface 12s, as shown in Fig. 2 or 3. In this case, only one identification means 40 may be provided on the upper shoe lower surface 12 excluding the upper shoe sliding surface 12s, or multiple identification means 40 may be provided.

[0025] When the identification means 40 is provided on the lower shoe 20, the identification means 40 is provided, for example, on the lower shoe side surface 23. The form in which the identification means 40 is provided on the lower shoe side surface 23 is similar to the case in which the identification means 40 is provided on the upper shoe side surface 13, and therefore a description thereof will be omitted. Alternatively, the identification means 40 may be provided on the lower shoe upper surface 21 of the lower shoe 20 excluding the lower shoe sliding surface 21s, as shown in Fig. 2 or 3. In this case, only one identification means 40 may be provided on the lower shoe upper surface 21 excluding the lower shoe sliding surface 21s, or multiple identification means 40 may be provided.

[0026] When the identification means 40 is provided on the sliding member 30, the identification means 40 is provided on the sliding portion side surface 33 as shown in Fig. 5. In this case, only one identification means 40 may be provided on the sliding portion side surface 33, or multiple identification means 40 may be provided. When multiple identification means 40 are provided on the sliding portion side surface 33, the identification means 40 may be provided, for example, lined up in the vertical direction or lined up in the horizontal direction. When the identification means 40 is provided on the sliding portion side surface 33, for example, in the spherical sliding bearing 100, it is preferable that the identification means 40 be provided at a position where it can be seen by looking into the sliding member 30 between the stopper rings S provided on each of the upper shoe 10 and the lower shoe 20.

[0027] (Shipping test system) Next, the delivery test system 200 according to this embodiment will be described with reference to FIG. FIG. 6 is a block diagram of a delivery test system 200 according to the embodiment. FIG. 7 is a schematic diagram of a biaxial shear testing apparatus 230. FIG. 8 is a displacement history curve of the spherical plain bearing 100 according to the test results of the biaxial shear test device 230. The shipment test system 200 is used to carry out a shipment test of the spherical sliding bearing 100 according to the present embodiment described above. The shipment test system 200 includes a reading means 210, a server 220, a biaxial shear test device 230, and the spherical sliding bearing 100.

[0028] (Reading means) The reading means 210 reads the identification means 40. The reading means 210 is, for example, a known barcode reader, a smartphone, a tablet PC, or the like. As described above, the identification means 40 includes, for example, information regarding the address of the server 220. In this case, when the reading means 210 reads the identification means 40, the server 220 can be accessed by a smartphone, a tablet PC, or the like. Alternatively, the identification means 40 itself indicates the various types of information. In this case, the reading means 210 reads the identification means 40, and it becomes possible to refer to the various types of information using a smartphone, a tablet PC, or the like.

[0029] (server) In response to the reading means 210 reading the identification means 40, the server 220 creates a folder corresponding to the spherical sliding bearing 100 that is equipped with the read identification means 40. Specifically, the server 220 first creates a pass folder and a fail folder. The server 220 also creates an object folder inside each of these folders. Furthermore, the server 220 creates folders inside the object folders that correspond to the test machine characteristic data, the test result data, and the like. The pass folder stores information about the spherical sliding bearings 100 that have passed the shipping test described below. The fail folder stores information about the spherical sliding bearings 100 that have not passed the shipping test described below. Information about each individual spherical sliding bearing 100 that has undergone the shipping test is stored in object folders created in a pass folder and a fail folder. At this time, information about each individual spherical sliding bearing 100 is stored in separate folders for testing machine characteristic data, which is data about the testing machine that performed the shipping test, and test result data, which is data about the results of the test.

[0030] The server 220 includes a receiving unit 221, a storage processing unit 222, and a storage unit 223. The receiving unit 221 receives information that the reading unit 210 has read the identification unit 40, and information included in the identification unit 40 read by the reading unit 210. In response to receiving the above-mentioned content, the receiving unit 221 instructs the storage processing unit 222, which will be described next, to perform storage processing. The storage processing unit 222 performs storage processing in response to the reading means 210 reading the identification means 40. The storage processing is processing for creating, in the storage unit 223 within the server 220, a folder corresponding to the spherical sliding bearing 100 equipped with the identification means 40 read by the reading means 210. The storage unit 223 is a part that stores various types of information in accordance with the storage processing of the storage processing unit 222.

[0031] In the folder created in the storage unit 223 of the server 220 by the above-mentioned storage process, for example, shipping test information showing the results of the shipping test of the sliding member 30 is stored. This makes it possible to manage information corresponding to each individual spherical sliding bearing 100 that has been made identifiable by the identification means 40 in a folder created in the server 220 corresponding to each individual. This makes it possible to prevent data mix-ups and tampering from occurring, compared to when an operator manually classifies and manages data, for example. Therefore, it is possible to prevent data mix-ups and tampering regarding various information.

[0032] (Biaxial shear test equipment) The biaxial shear test device 230 performs a performance test of the spherical sliding bearing 100 by reproducing the state in which the spherical sliding bearing 100 is installed in a building and the state in which an earthquake occurs in the building in which the spherical sliding bearing 100 is installed. Specifically, for example, the biaxial shear test device 230 can apply a weight equivalent to a building to the spherical sliding bearing 100 and apply a shear load in the horizontal direction. 7, the biaxial shear test apparatus 230 can be fitted with a configuration equivalent to the upper shoe 10 and the lower shoe 20 of the spherical sliding bearing 100. When testing the spherical sliding bearing 100, the sliding members 30, each of which can be individually identified by the above-mentioned identification means 40, are placed between the upper shoe 10 and the lower shoe 20 attached to the biaxial shear test apparatus 230. In this way, the spherical sliding bearing 100 is formed in the biaxial shear test apparatus 230 and a test is performed. Specifically, first, a constant load equivalent to the weight of a building is applied to the spherical sliding bearing 100 in the vertical direction using the biaxial shear test device 230. Then, repeated loading is performed on the spherical sliding bearing 100 in the horizontal direction. This allows the hysteresis characteristics of the horizontal load and horizontal displacement to be measured. A graph showing the characteristics of the spherical sliding bearing 100 measured by the biaxial shear test device 230 is shown in Fig. 8. In Fig. 8, the horizontal axis is the horizontal relative displacement between the upper shoe and the lower shoe of the spherical sliding bearing 100. In Fig. 8, the vertical axis is the value obtained by dividing the horizontal load by the vertical load. In the shipping test, we confirm that the value on the vertical axis (friction coefficient) when the horizontal displacement is 0 mm in the graph shown in Figure 8 is within the allowable value.

[0033] (Shipping test method for spherical sliding bearings) Next, a shipping test method for the spherical sliding bearing 100 using the above-mentioned shipping test system 200 will be described. The shipping test method according to this embodiment comprises a reading step and a creating step. In this embodiment, the reading step and the creating step are performed for each of the spherical sliding bearings 100 provided in the building. In other words, the reading step and the creating step are repeated the same number of times as the number of spherical sliding bearings 100 provided in the building.

[0034] (Read step) The reading step is a step of reading the identification means 40 using the reading means 210. That is, an operator reads the identification means 40 provided on the spherical sliding bearing 100 with the reading means 210, thereby identifying each of the spherical sliding bearings 100 provided in the building. By reading the identification means 40 in the reading step, the process moves to the creation step described next.

[0035] (Creation steps) The creating step is a step of creating a folder in which shipping test information showing the results of the shipping test of the spherical sliding bearing 100 or the sliding member 30 is stored in response to reading the identification means 40 in the reading step. Note that the results of the shipping test of the upper shoe 10 and the lower shoe 20 may be stored in the folder created in the creating step. In this embodiment, the folders created in the creation step include, for example, a pass folder corresponding to the upper shoe 10, the lower shoe 20, and the sliding member 30 having passed the shipping test, and a fail folder corresponding to the upper shoe 10, the lower shoe 20, and the sliding member 30 not having passed the shipping test. This makes it easy to understand whether the shipping test system 200 has passed or failed.

[0036] The shipping test is carried out, for example, by the biaxial shear test device 230 capable of applying a predetermined vertical load and horizontal displacement, according to the above-mentioned procedure. The shipping test described above is carried out for all of the spherical sliding bearings 100 installed in one building. The results of the above-mentioned shipping test are stored, for example, individually in a pass folder or a fail folder created in the memory unit 223 of the server 220. In this case, it is preferable to set detailed permissions so that the information in the folder cannot be deleted, modified, or overwritten. Alternatively, it is preferable that each individual spherical sliding bearing is automatically linked to the product performance test results corresponding to each individual, and that information is automatically stored in a folder. In this way, it is preferable that the information in the folder cannot be changed intentionally or unintentionally by humans. Alternatively, information regarding the results of the shipping test may be included in the identification means 40 so that it can be referenced by reading the identification means 40.

[0037] Here, as described above, the reading step and the creating step are repeated multiple times. At this time, in the first creating step of the multiple spherical sliding bearings 100 for one building, it is preferable to create an object folder that is a folder corresponding to the building. Then, it is preferable that folders corresponding to each of the multiple spherical sliding bearings 100 are created in the above-mentioned object folder.

[0038] (Shipping test flow) Next, the flow of a shipping test of the spherical sliding bearing 100 according to this embodiment will be described with reference to FIG. FIG. 9 is a flowchart of a shipping test according to the embodiment. First, in a reading step, an operator reads the identification means 40 using the reading means 210 (step S1). At this time, the fact that the reading means 210 has read the identification means 40 and the information included in the identification means 40 read by the reading means 210 are transmitted to the receiving unit 221 of the server 220. At this time, if an object folder has been created in the memory unit 223 of the server 220 (step S2: YES), the process proceeds to a creation step (step S3). In the creation step (step S3), the storage processing unit 222 stores the test results corresponding to each of the multiple spherical sliding bearings 100 in the object folder created in the memory unit 223. The object folder is a project folder corresponding to a building in which multiple spherical sliding bearings 100 are provided. In this way, the test results of each of the multiple spherical sliding bearings 100 arranged in one building are stored in a folder created in the object folder. In addition to the above-mentioned test results, data on the parts used in the manufacture of the spherical sliding bearings 100 and data related to manufacture may be stored in the object folder. The data on the parts includes, for example, dimensions and material mill sheets. The data related to manufacture includes, for example, data on painting, etc.

[0039] If an object folder has not been created in the memory unit 223 of the server 220 (step S2: NO), before proceeding to the creation step (step S3), the storage processing unit 222 creates an object folder in the memory unit 223 (step S4). Step S4 is executed, for example, when a shipping test is performed on the first spherical sliding bearing 100 out of multiple spherical sliding bearings 100 arranged in one building.

[0040] Then, various information corresponding to each of the spherical sliding bearings 100 is saved in a folder corresponding to each of the spherical sliding bearings 100 (step S5). For example, if the identification means 40 includes information regarding the address of the server 220, in step S5, the various pieces of information corresponding to each of the multiple spherical sliding bearings 100 previously stored in the memory unit 223 of the server 220 are stored in an object folder. Note that folders corresponding to each individual spherical sliding bearing 100 may be created inside the object folder, and the folders corresponding to each individual spherical sliding bearing 100 may store information corresponding to each individual bearing in an individual manner. For example, if the identification means 40 itself indicates the above various information, in step S5, the above various information read from the identification means 40 is stored in association with a folder corresponding to each individual spherical sliding bearing 100. The above flow is repeated for each of the plurality of spherical sliding bearings 100, thereby carrying out the shipping test according to this embodiment.

[0041] (Computer Configuration) 10 is a schematic block diagram showing the configuration of a computer 300 according to an embodiment. The computer 300 includes a processor 310, a main memory 320, and a storage 330. The above-mentioned server 220 is implemented in a computer 300. The operations of the above-mentioned components of the server 220, i.e., the receiving unit 221 and the storage processing unit 222, are stored in the storage 330 in the form of a program. The processor 310 reads the program from the storage 330, loads it in the main memory 320, and executes the above-mentioned processing in accordance with the program. The processor 310 also secures storage areas in the main memory 320 corresponding to the above-mentioned storage units 223 in accordance with the program. Examples of the processor 310 include a CPU (Central Processing Unit), a GPU (Graphic Processing Unit), and a microprocessor.

[0042] The program may be for realizing a part of the functions to be performed by the computer 300. For example, the program may be for realizing the functions by combining with other programs already stored in the storage 330 or by combining with other programs implemented in other devices. In another embodiment, the computer 300 may include a custom LSI (Large Scale Integrated Circuit) such as a PLD (Programmable Logic Device) in addition to the above configuration or instead of the above configuration. Examples of PLDs include PAL (Programmable Array Logic), GAL (Generic Array Logic), CPLD (Complex Programmable Logic Device), and FPGA (Field Programmable Gate Array). In this case, some or all of the functions to be realized by the processor 310 may be realized by the integrated circuit. Such an integrated circuit is also included in an example of the processor 310.

[0043] Examples of storage 330 include a magnetic disk, a magneto-optical disk, an optical disk, and a semiconductor memory. Storage 330 may be an internal medium directly connected to the bus of computer 300, or an external medium connected to computer 300 via a communication line. In addition, when the program is distributed to computer 300 via a communication line, computer 300 that receives the program may load the program into main memory 320 and execute the above-mentioned process. In at least one embodiment, storage 330 is a non-transitory tangible storage medium. The function of the memory unit 223 of the server 220 described above is realized by the storage 330 of the computer 300 .

[0044] The program may be for realizing part of the above-mentioned functions. Furthermore, the program may be a so-called difference file (difference program) that realizes the above-mentioned functions in combination with another program already stored in the storage 330. Furthermore, the server 220 may be implemented, for example, on a cloud.

[0045] As described above, the spherical sliding bearing 100 according to this embodiment is provided with an identification means 40 capable of identifying each individual spherical sliding bearing 100. This makes it possible to, for example, prevent mix-ups and tampering of various information corresponding to each individual spherical sliding bearing 100. Specifically, for example, manufacturing information and the like for each individual spherical sliding bearing 100 can be managed in association with each individual spherical sliding bearing 100. That is, for example, the aforementioned various pieces of information corresponding to each individual spherical sliding bearing 100 can be stored in and accessed from folders corresponding to each individual spherical sliding bearing 100 on the cloud.

[0046] Moreover, the identification means 40 is provided on the sliding member 30. This makes it possible to suppress, for example, mix-up and tampering of various information corresponding to each individual sliding member 30 of the spherical sliding bearing 100, in particular. Specifically, for example, the results of a shipping test performed on each individual sliding member 30 can be managed in association with each individual sliding member 30. That is, for example, the above-mentioned various information corresponding to each individual sliding member 30 can be stored and accessed in a folder corresponding to each individual sliding member 30 on the cloud.

[0047] Moreover, the identification means 40 is provided on the sliding portion side surface 33 that connects the upper sliding surface 31 and the lower sliding surface 32 of the sliding member 30. This makes it possible to easily confirm the position of the identification means 40 by visually checking the sliding member 30 from between the upper shoe 10 and the lower shoe 20, for example. Furthermore, for example, compared to a case where the identification means 40 is provided on the upper sliding surface 31 or the lower sliding surface 32 of the sliding member 30, it is possible to prevent the coefficient of friction of each sliding surface from being affected.

[0048] Furthermore, the identification means 40 is provided on the upper surface of the lower shoe 20 excluding the lower shoe sliding surface 21s. This allows the worker to easily confirm the position of the identification means 40 by visually checking the upper surface of the lower shoe 20. Therefore, the worker can grasp the position of the identification means 40 while the spherical sliding bearing 100 remains installed at the site. In addition, for example, compared to when the identification means 40 is provided on the lower shoe sliding surface 21s, in addition to preventing any effect on the friction coefficient of the lower shoe sliding surface 21s, the identification means 40 can be made less susceptible to damage.

[0049] Furthermore, the identification means 40 is provided on the underside of the upper shoe 10, excluding the upper shoe sliding surface 12s. This allows the worker to easily confirm the position of the identification means 40 by visually checking the underside of the upper shoe 10. Therefore, the worker can grasp the position of the identification means 40 while the spherical sliding bearing 100 remains installed at the site. In addition, for example, compared to when the identification means 40 is provided on the upper shoe sliding surface 12s, in addition to preventing any effect on the friction coefficient of the upper shoe sliding surface 12s, the identification means 40 can be made less susceptible to damage.

[0050] Furthermore, a plurality of identification means 40 are provided. This makes it easier for the worker to find the identification means 40. As a result, the task of checking the identification means 40 can be carried out efficiently.

[0051] Furthermore, the identification means 40 includes a tamper-proof seal 41. This makes it possible to make the identification means 40 difficult to tamper with. Therefore, mix-ups and tampering of various pieces of information corresponding to each individual spherical sliding bearing 100 can be more reliably prevented.

[0052] Moreover, the identification means 40 can identify the sliding member 30. This makes it possible to suppress misidentification and tampering of various information corresponding to each individual sliding member 30 of the spherical sliding bearing 100, particularly the individual sliding members 30. Specifically, for example, the results of a shipping test performed for each individual sliding member 30 can be managed in association with each individual sliding member 30. That is, for example, the above-mentioned various information corresponding to each individual sliding member 30 can be stored and accessed in a folder corresponding to each individual sliding member 30 on the cloud.

[0053] Moreover, according to the shipping test method of this embodiment, first, the identification means 40 is read in a reading step. Then, in response to reading the identification means 40 in the reading step, a folder is created in a creation step in which shipping test information showing the results of the shipping test of the sliding member 30 is stored. This makes it possible to reliably create a corresponding folder for each of the spherical sliding bearings 100 identified by the identification means 40. This makes it possible to prevent mix-ups and tampering with various information corresponding to each individual spherical sliding bearing 100. That is, for example, the results of the shipping test of the sliding member 30 provided in each individual spherical sliding bearing 100 can be reliably stored in the corresponding folder.

[0054] Moreover, according to the shipment test system 200 of this embodiment, first, the reading means 210 reads the identification means 40. Then, in response to the reading means 210 reading the identification means 40, the server 220 creates a folder in which the shipment test information showing the results of the shipment test of the sliding member 30 is stored. This makes it possible to reliably create a corresponding folder for each of the spherical sliding bearings 100 identified by the identification means 40. This makes it possible to prevent mix-ups and tampering with various information corresponding to each individual spherical sliding bearing 100. That is, for example, the results of the shipment test of the sliding member 30 included in each individual spherical sliding bearing 100 can be reliably stored in the corresponding folder.

[0055] Second embodiment Next, a spherical sliding bearing 100 according to a second embodiment of the present disclosure will be described with reference to FIGS. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and their description will be omitted, with only the differences being described.

[0056] The spherical sliding bearing 100 according to the second embodiment differs from the first embodiment in that it is a so-called single pendulum type spherical sliding bearing. As a single pendulum type spherical sliding bearing 100, for example, examples as shown in Figs.

[0057] FIG. 11 shows a first example of a single pendulum type spherical sliding bearing 100. In the spherical sliding bearing 100 shown in FIG. 11, the curvature of the sliding surface between the lower shoe 20 and the sliding member 30, i.e., the lower sliding surface 32, is greater than the curvature of the sliding surface between the upper shoe 10 and the sliding member 30, i.e., the upper sliding surface 31. As a result, the sliding member 30 rotates around the center of curvature of the lower shoe sliding surface 21s of the lower shoe 20 as the center of rotation. Therefore, in the spherical sliding bearing 100 shown in FIG. 11, the lower shoe 20 and the sliding member 30 do not move relative to each other in the horizontal direction. Since the lower shoe 20 is connected to the upper part of the lower structure B and does not move in the horizontal direction, in the spherical sliding bearing 100 shown in FIG. 11, the sliding member 30 does not move in the horizontal direction. And only the upper shoe 10 is displaced in the horizontal direction. In the spherical sliding bearing 100 shown in FIG. 11, the identification means 40 is preferably attached to, for example, the sliding part side surface 33 of the sliding member 30. Alternatively, the identification means 40 may be attached to any portion of the spherical sliding bearing 100, similarly to the first embodiment.

[0058] FIG. 12 shows a second example of a single pendulum type spherical sliding bearing 100. In the spherical sliding bearing 100 shown in FIG. 12, the curvature of the sliding surface between the upper shoe 10 and the sliding member 30, i.e., the upper sliding surface 31, is greater than the curvature of the sliding surface between the lower shoe 20 and the sliding member 30, i.e., the lower sliding surface 32. As a result, the sliding member 30 rotates around the center of curvature of the upper shoe sliding surface 12s of the upper shoe 10 as the center of rotation. Therefore, in the spherical sliding bearing 100 shown in FIG. 12, the upper shoe 10 and the sliding member 30 do not move relative to each other in the horizontal direction. In the spherical sliding bearing 100 shown in FIG. 12, the sliding member 30 moves in the horizontal direction in accordance with the movement of the upper shoe 10 in the horizontal direction, which is different from the first example of the spherical sliding bearing 100 shown in FIG. 11. 12, the identification means 40 is preferably attached, for example, to the sliding portion side surface 33 of the sliding member 30. Alternatively, the identification means 40 may be attached to any portion of the spherical sliding bearing 100, as in the first embodiment.

[0059] The technical scope of the present disclosure is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present disclosure. For example, the spherical sliding bearing 100 may be a so-called triple pendulum type spherical sliding bearing.

[0060] In addition, within the scope of the present disclosure, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described modified examples may be combined as appropriate. [Explanation of symbols]
