Of the restraint fixing portions 34 located on the lower flange plate 33 in FIG. 2, the restraint fixing portion 34b located diagonally to the upper left restraint fixing portion 34a (in FIG. 2, the right side of the lower flange plate 33). It is provided in the restraint fixing portion 34b (hereinafter, referred to as “lower right restraint fixing portion 34b”) located on the side. Here, since the configurations of the first connecting portion 60 and the second connecting portion 70 are substantially the same, only the configuration of the first connecting portion 60 will be described below. As shown in FIGS. 2 and 3, the first connecting portion 60 includes a first connecting plate 61, a second connecting plate 62, a first splicing plate 63, and a second splicing plate 64.

Of these, the first connecting plate 61 is for connecting the restraint main body 50 (specifically, the first restraint main body 51) and the upper left restraint fixing portion 34a, and is, for example, a steel plate. It is a shape, is provided so as to project from the restraint main body 50 toward the upper left restraint fixing portion 34a, and is connected to the restraint main body 50 by welding or the like.

It is a body, is provided so as to project from the upper left restraint fixing portion 34a toward the restraint main body 50, and is connected to the upper left restraint fixing portion 34a by a fixing tool or welding or the like. Further, the first auxiliary plate 63 and the second auxiliary plate 64 are for connecting the first connecting plate 61 and the second connecting plate 62, and are formed of, for example, a steel plate-like body. Further, the first auxiliary plate 63 is provided so as to be in contact with the front surfaces of the first connecting plate 61 and the second connecting plate 62, and the second auxiliary plate 64 is the rear surface of the first connecting plate 61 and the second connecting plate 62. It is provided so as to come into contact with.

The specific configuration of the first connecting portion 60 is arbitrary, but in the first embodiment, when the restraint 40a receives an external force (specifically, a tensile force) of less than a predetermined amount, the restraint 40a receives an external force (specifically, a tensile force). When the restraint of the seismic isolation device 30 (specifically, the seismic isolation device main body 31) is maintained and the restraint tool 40a receives an external force of a predetermined amount or more, the seismic isolation device 30 is separated by the separation of the first connection portion 60. It is formed to release the restraint of. Specifically, as shown in FIG. 3, the first connecting plate 61 is the mounting of FIG. 3 (c) formed on each of the first connecting plate 61, the first auxiliary plate 63, and the second auxiliary plate 64. A bolt 65a (for example, a high-strength bolt) and a nut 66a of FIGS. There is. Further, the second connecting plate 62 has a notch 62a formed in the second connecting plate 62 and a mounting hole formed in each of the first auxiliary plate 63 and the second auxiliary plate 64 (not shown). (Omitted), the first splicing plate 63 and the second splicing plate 64 are joined (friction-joined) by the bolt 65b (for example, a high-strength bolt) and the nut 66b of FIGS. 3 (a) and 3 (b). There is. Here, as shown in FIG. 3C, the notch portion 62a is formed in a range extending from the end portion of the second connecting plate 62 on the restraint body 50 side to the portion corresponding to the bolt 65b inserted. Therefore, the state in which the second connecting plate 62 and each of the first auxiliary plate 63 and the second auxiliary plate 64 are connected can be released (that is, the second connecting plate 62 is connected to the first auxiliary plate 63 and the second auxiliary plate 64). Can be separated from). Further, among the side surfaces of the second connecting plate 62, the side surface in contact with the first auxiliary plate 63 or the second auxiliary plate 64 (in FIG. 3B, the front surface and the rear surface of the second auxiliary plate 62) and the first attachment. Of the side surfaces of the plate 63 and the second splicing plate 64, the side surface in contact with the second connecting plate 62 (in FIG. 3B, the rear surface of the first splicing plate 63 and the front surface of the second splicing plate 64). Is subjected to surface treatment (for example, shot blasting treatment, sandblasting treatment, etc.) on the abutting side surface. Regarding the desired frictional force obtained by tightening the bolts 65b and friction between the surface treatments, when the restraint 40a receives an external force of a predetermined amount or more, the second connecting plate 62 is attached to the first auxiliary plate 63 and The size is set so that it can be separated from the second attachment plate 64.

When the restraint 40a receives an external force of a predetermined amount or more by such a first connection portion 60, the restraint of the seismic isolation device 30 can be released by separating the first connection portion 60, and the seismic isolation device 30 can be released. It is possible to reliably restrain and release. In particular, a part of the first connecting portion 60 (specifically, the second connecting plate 62) and another part of the first connecting portion 60 (specifically, the second connecting plate 62, the second connecting plate 62) are friction-bonded. The 1st splicing plate 63 and the 2nd splicing plate 64) can be separated. Therefore, the first connection portion 60 can be separated with a simple structure without damaging the first connection portion 60, the restraint 40a can be easily restored after the separation, and the restraint 40a can be manufactured easily. Can be improved. Further, since the restraint main body 50 of the restraint 40a hangs down after the separation of the first connection portion 60, the restraint main body 50 causes the seismic isolation device 30 (specifically, the seismic isolation device main body 31). It is possible to avoid hindering repeated deformation. The above-mentioned first connection unit 60 and second connection unit 70 correspond to "binding means" within the scope of the claims.

Further, with the above-mentioned restraint tool 40a, the seismic isolation device 30 is used depending on the situation, as compared with the conventional technique (a technique for restraining the seismic isolation device so that the seismic isolation device does not function regardless of the magnitude of the external force). It is possible to control the restraint and release of the building 1, and it is possible to improve the stability of the building 1 under construction while ensuring the structural soundness and safety of the building 1 under construction. In addition, restraint means can be provided in the first connection portion 60 and the second connection portion 70 depending on the situation, and the installability or manufacturability of the restraint 40a can be improved.

(About the action of restraints)
Next, the operation of the restraint 40 configured in this way will be described.

First, when a horizontal seismic force is applied to the seismic isolation device 30, the relative displacement between the upper flange plate 32 and the lower flange plate 33 of the seismic isolation device 30 tends to occur, so that the seismic isolation device 30 is attached. A plurality of restraining tools 40 are subjected to an external force (tensile force). Here, when the plurality of restraints 40 receive an external force less than a predetermined amount, the first connection portion 60 and the second connection portion 70 of the plurality of restraints 40 are not separated from each other, so that the plurality of restraints 40 The seismic isolation device 30 (specifically, the seismic isolation device main body 31) is restrained by this. Therefore, in this case, the seismic isolation device 30 does not function because the relative displacement does not occur. On the other hand, when the plurality of restraints 40 receive an external force of a predetermined amount or more, the first connection portion 60 or the second connection portion 70 of each of the plurality of restraints 40 is separated, so that the plurality of restraints 40 are separated. The restraint of the seismic isolation device 30 is released. Therefore, in this case, since the relative displacement occurs, the seismic isolation device 30 can function (specifically, the seismic isolation device main body 31 can be deformed in the horizontal direction).

(Regarding the restraint method)
Subsequently, a restraint method using the restraint tool 40 will be described. FIG. 4 is a perspective view showing a restrained state of the seismic isolation device 30 of the building 1 by the restraint 40, and FIG. 4A shows a state when the height of the building 1 is the first height H1 described later. FIG. 3B is a diagram showing a state when the height of the building 1 is the second height H2 described later, and FIG. 3C is a diagram showing the state when the height of the building 1 is the third height H3 described later. It is a figure which shows the state of. This restraint method is a method for restraining the seismic isolation device 30 or the vibration control device of the building 1 under construction, and includes an installation step, a restraint step, and a release step.

Of these, the "installation process" is a process of installing a plurality of seismic isolation devices 30 or vibration control devices in the building 1. Further, the "restraint step" is a step of restraining a plurality of seismic isolation devices 30 or vibration control devices by the restraint 40 either before or after the installation step. Further, the "release step" is a step of gradually releasing the restraint of the plurality of seismic isolation devices 30 or the vibration control devices by the restraint 40 according to the construction status of the building 1 after the restraint step.

First, in the installation process, as shown in FIG. 4A, when the building 1 is constructed so that the height of the building 1 reaches the first height H1, a plurality of seismic isolation devices 30 are installed. Specifically, they are installed in 4 rows in the left-right direction and 5 rows in the front-rear direction at intervals between the lowermost floor portion 20 of the building 1 and the installation surface 2. A total of 20 seismic isolation devices 30 will be installed). Here, the "first height H1" means the height of the building 1 under construction, which is lower than the height of the building 1 after construction.

Next, in the restraint step, after the installation step, all of the plurality of seismic isolation devices 30 are restrained by the restraint 40 (in FIG. 4A, all the seismic isolation devices 30 are restrained. 30a). Regarding the method of restraining each seismic isolation device 30, as described above, in the first embodiment, the restraint 40 is attached to each of the front side, the rear side, the left side, and the right side of each seismic isolation device 30. It is restrained by providing it so that it intersects two by two.

Next, in the release step, after the restraint step, the restraint of the plurality of seismic isolation devices 30 by the restraint 40 is gradually released according to the construction status of the building 1.

Further, the specific release method of the plurality of seismic isolation devices 30 is arbitrary, but in the first embodiment, as the height of the building 1 increases, the inside of the building 1 among the plurality of seismic isolation devices 30 In order from the seismic isolation device 30 located in the building 1 to the seismic isolation device 30 located outside the building 1, the restraints of the plurality of seismic isolation devices 30 by the restraint 40 are released. Specifically, first, as shown in FIG. 4B, when the building 1 is constructed so that the height of the building 1 reaches the second height H2, the building 1 is out of the plurality of seismic isolation devices 30. In FIG. 4B, some seismic isolation devices 30 are referred to as restrained seismic isolation devices 30a, and some other seismic isolation devices 30 are released from the restraints of the six seismic isolation devices 30 located inside. The device 30 is referred to as a released seismic isolation device 30b). Then, as shown in FIG. 4C, when the building 1 is constructed so that the height of the building 1 reaches the third height H3, the remaining seismic isolation device 30 (of the plurality of seismic isolation devices 30) ( That is, 14 seismic isolation devices 30) located outside the building 1 are released (in FIG. 4C, all seismic isolation devices 30 are referred to as released seismic isolation devices 30b). Here, the "second height H2" is the height of the building 1 under construction, which is lower than the height of the building 1 after construction and higher than the first height H1. Means height. Further, the "third height H3" is the height of the building 1 after the construction is completed, and means a height higher than the second height H2.

By the restraint method as described above, the seismic isolation device 30 functions reliably in the event of a relatively large-scale earthquake, as compared with the case where the restraint of the plurality of seismic isolation devices 30 by the restraint tool 40 is not gradually released. This makes it easier to ensure the structural soundness and safety of the building 1 under construction. In particular, in the release process, as the height of the building 1 increases, the seismic isolation device 30 located inside the building 1 among the plurality of seismic isolation devices 30 reaches the seismic isolation device 30 located outside the building 1. Since the restraints of the plurality of seismic isolation devices 30 by the restraint tool 40 are released in order, the restraint tool 40 is used in the order from the seismic isolation device 30 located outside the building 1 to the seismic isolation device 30 located inside the building 1.
