Although it is desirable that the pin support (ball seat) 4 is installed in a place where there is no hindrance in terms of manufacturing and construction, and within the range where there is no hindrance in terms of load transmission, The shaking rack 8 is installed on the pin support (ball seat) 4 and joined.
If the area where the pin bearing (ball seat) 4 is placed is sufficiently small compared to the total area of the seismic isolation bearing and the bending is not transmitted so much, instead of the pin bearing (ball seat) 4, the upper part of the plate The support material joint portion 3-c may be used. Also, even when the upper support joint portion 3-c is installed, since the bending is not transmitted when the pin support (ball seat) 4 is placed, more uniform load can be obtained in the seismic isolation support. -c may be replaced with a pin support (ball seat) 4.
In this example, the example of the double seismic isolation plate-isolated bearing 1-w is given as the seismic isolation bearing, but other rolling seismic isolation bearings are possible as well, but the area is compact. Considering this, the double seismic isolation plate 1-w is advantageous. In particular, the double seismic isolation plate 1-w with the mortar and spherical gradient is particularly advantageous.

FIG. 8 shows an embodiment of the pin support (ball seat) 4. (a) is a sectional view and (b) is an exploded perspective view.
This is for evenly transmitting the load from the base isolation structure (building) D to each double base isolation base isolation base 1-w.
360 degrees in the horizontal plane allows rotation in any direction in the vertical plane, and does not transmit the bending from the base isolation frame 8 to each support, and evenly loads from the base isolation frame 8 It plays the role of transmitting to each double seismic isolation plate 1-w.
The pin support (ball seat) 4 is composed of a ball seat tray 4-b and a ball seat 4-a. In FIG. 8, although it consists of the top ball seat receiving tray 4-b and the lower ball seat 4-a, there are cases where the top and bottom are reversed. In that case, it consists of an upper ball seat 4-a and a lower ball seat tray 4-b. The spherical seat 4-a is a partial spherical surface such as a convex hemispherical surface. The ball seat receiving tray 4-b has a concave shape for receiving the partial spherical surface. In FIG. 8, the ball seat 4-a is bolt-joined, but the joining method such as welding joining or joining with an adhesive is not limited.
If the area where the pin bearing (ball seat) 4 is placed is sufficiently small compared to the total area of the seismic isolation bearing and the bending is not transmitted so much, instead of the pin bearing (ball seat) 4, the upper part of the plate The support material joint portion 3-c may be used. Also, even when the upper support joint portion 3-c is installed, since the bending is not transmitted when the pin support (ball seat) 4 is placed, more uniform load can be obtained in the seismic isolation support. -c may be replaced with a pin support (ball seat) 4.

FIG. 9 shows an embodiment in which the upper support material joint portion 3-c, which is a simple plate material, is used instead of the pin support (ball seat) 4. (a) is a sectional view and (b) is an exploded perspective view. The upper support joint joint receiver 4-c is simply placed on the upper support joint joint 3-c. However, the upper stopper 4-d is placed on the top to prevent shearing and to prevent disconnection and falling off. It is attached to the support material joint receiver 4-c. Further, an effect of not transmitting the bending can be obtained by providing a slightly spherical surface on the upper surface of the upper support material joint portion 3-c (the portion in contact with the upper support material joint portion receiver 4-c).
The bolt 5 penetrating the ball seat 4-b in FIG. 8 and the bolt 5 penetrating the upper support member joint 4-c in FIG. 9 are the ball seat pan 4-b and the upper support joint joint 4- Although the diameter of the through hole of c is increased to allow rotation, the bolt 5 itself may not be necessary.

FIGS. 10 to 12 are embodiments of the invention relating to the seismic isolation bearing (four seismic isolation base seismic isolation four arrangements) comprising four balls (rolling elements) according to claim 3 or claim 16. . 10 is a sectional view, FIG. 11 is a perspective view, and FIG. 12 is an exploded perspective view.
In seismic isolation bearings consisting of four balls (rolling elements) (4 seismic isolation plates with 4 seismic isolation bases), the load from the seismic isolation rack 8 is passed through the upper support beam 3-d at two locations. The upper support material joint portion 3-c transmits the vibration to the four balls (rolling elements) 1-b of the seismic isolation bearing evenly.
The upper support material 3-a is composed of four double base isolation plates 1-w, arranged in a 2 × 2 (equal) grid, and the load from the base 8 Since it is intended to transmit to four balls (rolling elements) 1-b, the upper two base isolation plates 1-w of the four double base isolation plates 1-w can be joined together. It is necessary to have a size and shape that encompass the quadrangle formed by the center of the four balls (rolling elements) 1-b of the double base plate 1-w.
In addition, since the upper support member 3-b is for transmitting the load from the base isolation frame 8 to the four balls (rolling elements) 1-b, the double base isolation plate base isolation bearing 1 The size and shape of the quadrangle formed by the center of the four balls (rolling elements) 1-b of -w are required.
Joining the upper support material 3-a and four double base isolation plates 1-w to the upper base plate 1-u and reinforcing the upper support material 3-a directly above the upper support material The joining with the material 3-b is not particularly limited, such as bolt joining, welding joining, joining with an adhesive, and the like. Moreover, it may be integral with cast steel etc.
The upper support material joint portion 3-c is composed of four balls (rolling elements) on the upper support material 3-a or the upper support material 3-b directly above the upper support material 3-b which is provided with four base isolation plates. ) The center part of the straight line connecting the centers of the two balls (rolling elements) 1-b in the two sets of balls (rolling elements) 1-b of 1-b And may be displaced from the center point within the range where there is no hindrance in terms of load transmission and construction) (FIG. 44 (c)).
The upper support material beam portion 3-d is installed on the upper support material joint portion 3-c at two locations so as to straddle, and is joined to the upper support material joint portion 3-c.
In the embodiment of FIGS. 3 to 5, the load from the seismic isolation gantry 8 is supported by the four fulcrums (four balls (rolling elements) 1-b) from the pin bearing (ball seat) 4. Since it acts as a concentrated load on the central part of the upper support member 3-a and the upper support member 3-b, which is a member (FIG. 44 (a)), the upper support The plate thickness of the directly upper member 3-a and the upper support member 3-b is also increased.
In the embodiment shown in FIGS. 10 to 12, the concentrated load is dispersed by the two upper support material joint portions 3-c, so that the upper support material 3-a and the upper support material 3-b directly above the upper support material 3-b. The plate thickness can be reduced.
As for the position of the upper support joint portion 3-c, the joint portion is divided into two sets of four balls (rolling elements) and two straight lines connecting the centers of the two balls (rolling elements). On the straight line connecting each central part (desired to be the center point, but may be displaced from the center point within the range where there is no hindrance in terms of load and transmission due to manufacturing and construction) When the straight line is located at two positions substantially symmetrical with respect to the center line orthogonal to the straight line (FIG. 44 (b)), the load from the upper support joint portion 3-c is four balls (rolling elements) 1 Acts equally on -b. Among them, the embodiment of FIG. 10 to FIG. 12 (FIG. 44 (c)) is such that the load point (upper support material joint portion 3-c) and the support point (ball (rolling body)) are the closest distance. This is an example in which the plate thicknesses of the upper support material 3-a and the upper support material 3-b can be reduced most. The upper support beam portion 3-d is a thick plate-like member in FIGS. 10 to 12, but the shape of the upper support beam portion 3-d is shaped steel, as long as it does not interfere with load transmission. A cross-sectional shape such as a steel plate or a steel bar is not limited.
Using lower profile cross-section members as the upper support beam 3-d can reduce the depth of the foundation (root cutting depth) and reduce costs in earthwork and foundation work. Can do.
The four units of the double seismic isolation plate 1-w having one ball (rolling element) arranged in a 2 × 2 (equal) grid are integrated into the upper part of each unit. There may be a seismic isolation bearing with four balls (rolling elements) consisting of a base isolation tray and a lower base isolation tray (in this case, if the base isolation tray of this base isolation bearing has sufficient rigidity, The upper support material 3-a of the upper support material may not be required).
Further, there is a case where the base is joined to the lower base plate 1-d of the double base plate 1-w without the lower support material 2. Further, the reinforcing material 3-b directly above the upper support member is not required when the upper supporting material 3-a has sufficient rigidity.

FIGS. 13 to 15 show the invention relating to the seismic isolation bearing (eight seismic isolation base seismic isolation eight arrangements) composed of eight balls (rolling elements) according to claim 1, claim 4 or claim 16. This is an example. 13 is a sectional view, FIG. 14 is a perspective view, and FIG. 15 is an exploded perspective view.
Four of the double seismic isolation plates 1-w are arranged in a 2x2 (equal) grid and are integrated into a single set. In some cases).
The four sets of double seismic isolation plates 1-w arranged in this way have four balls (rolling elements) consisting of upper and lower seismic isolation plates, respectively. There is also a case of a seismic bearing (in this case, if the seismic isolation plate of this seismic isolation bearing has sufficient rigidity, either the upper support material 3-b or the upper support material 3-a below is used. Or both may be unnecessary). FIGS. 16 to 17 show an embodiment in which the upper support material 3-a is not required. 16 is a cross-sectional view, and FIG. 17 is a perspective view.
The other set, 4 units of double seismic isolation plate-isolated bearings 1-w, has the same configuration, and both sets of double seismic isolation plate-isolated bearings 1-w are placed in contact with each other (group In some cases, a slight gap may be provided in consideration of manufacturing and construction errors.
Although the four sets of these double base isolation plates 1-w are arranged in contact with each other, they are independent of each other (there is no stress transmission in both), and each has a vertical error ( By being able to follow (non-land), the problem that the load is hardly transmitted to the ball (rolling element) resulting from the integration is solved.
The upper support material 3-a and the upper support material 3-b, if necessary, are installed on the upper part of each of the four double-isolated plate-isolated bearings 1-w. (The upper support material directly above the reinforcing material 3-b is not necessary when the upper support material directly above the material 3-a has sufficient rigidity). In addition, a lower support member 2 is installed on the lower part of each of the four lower base isolation plates 1-d of the double base isolation plate 1-w as required (if there is no lower support member 2) There is also.) The lower base plate 1-d of the double base plate 1-w and the base are directly connected to the foundation (FIGS. 16 to 17 are examples thereof) or the lower support member 2 and the base are joined. Is done.
Then, the center part on the upper support member 3-a or the upper support member 3-b directly above the upper support member 3-b, in which the four base isolation plates are installed (four balls of the base support ( Rolling element) The central part of the plane formed by the center of 1-b, which is preferably the central part, but deviates from the central part within the range where there is no hindrance in terms of manufacturing and construction, and in terms of load transmission. In some cases, the upper support material joint portion 3-c is installed (FIG. 44 (a)).
Here, the upper support material 3-a is composed of four double base isolation plates 1-w, and the load from the base 8 is four balls (rolling elements) 1-b. The size and shape of the upper two base isolation plates 1-u of the four double base isolation plates 1-w can be joined to each other. The size and shape of the quadrangle formed by the center of the four balls (rolling elements) 1-b of the seismic isolation plate 1-w are required.
In addition, since the upper support member 3-b is for transmitting the load from the base isolation frame 8 to the four balls (rolling elements) 1-b, the double base isolation plate base isolation bearing 1 The size and shape of the quadrangle formed by the center of the four balls (rolling elements) 1-b of -w are required.
Joining the upper support material 3-a and four double base isolation plates 1-w to the upper base plate 1-u and reinforcing the upper support material 3-a directly above the upper support material The joining with the material 3-b is not particularly limited, such as bolt joining, welding joining, joining with an adhesive, and the like. Moreover, it may be integral with cast steel etc.
Furthermore, the upper support material joint part 3-c is for transmitting the load from the base isolation rack 8 evenly to the four balls (rolling elements) 1-b. It must be installed in the center of a quadrangle formed by the center of four 1-w balls (rolling elements) 1-b and must have a size and shape that can transmit the load from the seismic isolation rack 8.
However, a part (peripheral part) of the upper support material joint portion 3-c overlaps with the position of the ball (rolling element), and the upper support material 3-a and the upper support material 3 just above the upper support material at the lower part thereof. As a result of the combined effect with -b, the rigidity between the load point (the center point of the upper support joint portion 3-c) and the support point (ball (rolling element)) is increased, and the load is concentrated on the ball. It is desirable not to make it larger (wider) than necessary.
The upper support material beam portion 3-d is installed on the upper support material joint portion 3-c in two places in a straddling manner, and is joined to each of the upper support material joint portions 3-c.
The joint between the upper support member 3-b and the upper support joint part 3-c, and the joint between the upper support joint part 3-c and the upper support beam part 3-d are bolt joints and weld joints. There is no particular limitation such as bonding with an adhesive. Moreover, it may be integral with cast steel etc.

Further, a pin support (ball seat) 4 is installed at the center of the upper support beam portion 3-d, and the seismic isolation rack 8 is installed on the pin support (ball seat) 4 and joined thereto. The base isolation frame 8 supports the base isolation structure (building) D.
With the above configuration, the load via the base isolation frame 8 of the base isolation structure (building) D is evenly transmitted to each double base isolation base isolation base 1-w.
If the area where the pin bearing (ball seat) 4 is placed is sufficiently small compared to the total area of the seismic isolation bearing and the bending is not transmitted so much, instead of the pin bearing (ball seat) 4, the upper part of the plate The support material joint portion 3-c may be used. Also, even when the upper support joint portion 3-c is installed, since the bending is not transmitted when the pin support (ball seat) 4 is placed, more uniform load can be obtained in the seismic isolation support. -c may be replaced with a pin support (ball seat) 4.
In this example, the example of the double seismic isolation plate-isolated bearing 1-w is given as the seismic isolation bearing, but other rolling seismic isolation bearings are possible as well, but the area is compact. Considering this, the double seismic isolation plate 1-w is advantageous. In particular, the double seismic isolation plate 1-w with the mortar and spherical gradient is particularly advantageous.

18 to 20, in the examples of FIGS. 13 to 15 (8 double-plate seismic isolation bases are arranged), a thick plate is used instead of a section steel for the upper support beam portion 3-d. It is an example. 18 is a sectional view, FIG. 19 is a perspective view, and FIG. 20 is an exploded perspective view. In this case, the height of the upper support beam 3-d can be reduced, and as a result, the depth of the foundation (root cutting depth) becomes shallow, reducing costs in earthwork and foundation work. can do. Note that the shape of the upper support beam portion 3-d is not limited to a cross-sectional shape such as a shape steel, a steel plate, or a steel bar as long as it does not interfere with load transmission.

FIG. 44 (b) shows the invention relating to the seismic isolation bearing (eight seismic isolation base seismic isolation eight arrangements) consisting of eight balls (rolling elements) according to claim 1, claim 5 or claim 16. This is an example, and a set of four seismic isolation bearings arranged side by side in a 2 × 2 (equal) grid and integrated with each other, a load point (upper support joint portion 3-c) and a support point (ball ( It shows the positional relationship with the rolling elements)).
In the embodiment shown in FIG. 13 to FIG. 15 (eight seismic isolation plate seismic isolation bearings are arranged), the force acting on the four balls (rolling elements) 1-b is applied to one upper support joint portion 3-c. The upper support member directly above the upper support member 3-a and the upper support member directly above the reinforcing member 3 are flat members supported by the four supporting points (four balls (rolling elements) 1-b). Since it acts as a concentrated load at the central part of -b, when the force becomes large, the plate thickness of the upper support material 3-a and the upper support material 3-b directly increases.
FIG. 44 (b) shows that four balls (rolling elements) are divided into two groups of two, and each center part (center point) of the straight lines connecting the centers of the two balls (rolling elements). Although it is desirable, it may be displaced from the center point within the range where there is no hindrance in terms of manufacturing and construction, and in terms of load transmission). By providing joints at two locations that are almost line-symmetrical and installing the upper support joint 3-c, the load from the seismic isolation rack 8 is evenly transmitted to the four balls (rolling elements). At the same time, by dispersing one concentrated load into two, it is an embodiment that can reduce the plate thickness of the upper support material 3-a and the upper support material 3-b.

FIGS. 21 to 23 show the invention relating to the seismic isolation bearing (eight seismic isolation base seismic isolation base arrangement) consisting of eight balls (rolling elements) according to claim 1, claim 6 or claim 16. This is an example. 21 is a sectional view, FIG. 22 is a perspective view, and FIG. 23 is an exploded perspective view.
FIGS. 21 to 23 show the upper support material 3-a and the upper support material immediately above in the embodiment shown in FIGS. 13 to 15 and FIG. 44 (b) (eight seismic isolation plates are installed). In order to reduce the plate thickness of the reinforcing material 3-b, it is the most effective (the thickness of the upper supporting material 3-a and the upper supporting material 3-b can be made the thinnest). is there.
Two sets of four balls (rolling elements) 1-b on the upper support material 3-a or the upper support material 3-b directly above the upper support material 3-a, which has four double base isolation plates The center part of the straight line connecting the centers of the two balls (rolling elements) 1-b in the ball (rolling element) 1-b (preferably the center point, but also due to the manufacturing and construction, the load This is an example in which the upper support joint portions 3-c are respectively installed in a range where there is no hindrance in terms of transmission, which may deviate from the center point (FIG. 44 (c)).
The upper support material beam portion 3-d is installed on the upper support material joint portion 3-c of each of the four locations in a shape of being H-shaped so as to straddle the upper support material joint portion 3-c. Be joined.
In the embodiment shown in FIGS. 13 to 15, forces acting on four balls (rolling elements) 1-b act on one upper support joint portion 3-c, and these forces are applied to four fulcrums (4 Since it acts as a concentrated load at the center of the upper support material 3-a and the upper support material 3-b, which are flat members supported by two balls (rolling elements) 1-b), When the force becomes large, the plate thickness of the upper support member 3-a and the upper support member 3-b directly increases.
On the other hand, in the embodiment shown in FIGS. 21 to 23, the force acting on the two balls (rolling elements) 1-b acts on one upper support joint portion 3-c. Four support points (balls) on the upper support material 3-a and the upper support material 3-b, which are flat members supported by the four support points (ball (rolling element) 1-b). (Rolling elements) 1-b) will be distributed and act on the center points of the opposing straight lines, and the load will be applied evenly to the four balls (rolling elements) 1-b. Compared with the embodiment shown in FIGS. 13 to 15, the upper support in the embodiment shown in FIG. 44 (b) is that the support material joint portion 3-c) and the support point (ball (rolling element)) are closest to each other. The plate thickness of the material directly above the material 3-a and the upper support material directly above the reinforcing material 3-b can be reduced most.

FIG. 24 to FIG. 26 show the invention relating to the seismic isolation bearing (16 seismic isolation plates 16 seismic isolation arrangement) consisting of 16 balls (rolling elements) according to claim 1, claim 7 or claim 16. This is an example. 24 is a sectional view, FIG. 25 is a perspective view, and FIG. 26 is an exploded perspective view.
Four of the double seismic isolation plates 1-w are arranged in a 2x2 (equal) grid and are integrated into a single set. In some cases).
The four groups of double seismic isolation plates 1-w with one ball (rolling element) arranged in this way are composed of a single upper and lower seismic isolation plate, respectively. In some cases, the base isolation bearing has four balls (rolling elements) (in this case, if the base isolation tray of this base isolation bearing has sufficient rigidity, Either the upper support material 3-a or the both may be unnecessary). FIGS. 27 to 28 show an embodiment in which the upper support material 3-a is not required. 27 is a sectional view, and FIG. 28 is a perspective view.
There are 4 sets of 4 double-isolated plate-isolated bearings 1-w with the same structure, and 4 sets of 4 double-isolated plate-isolated bearings 1-w touch each other in the shape of a grid. (Some gaps may be provided between the groups in consideration of manufacturing and construction errors).
Although these four sets are arranged in contact with each other, they are independent (no stress transmission in both), and each can follow an error in the vertical direction (non-land), resulting from unity. It solves the problem that the load is difficult to be evenly transmitted to the ball (rolling element).
The upper support material 3-a and the upper support material 3-b, if necessary, are installed on the upper part of each of the four double-isolated plate 1-w. The reinforcing material 3-b directly above the upper support member is not necessary if the upper supporting material 3-a has sufficient rigidity. In addition, a lower support member 2 is installed on the lower part of each of the four lower base isolation plates 1-d of the double base isolation plate 1-w as required (if there is no lower support member 2) There is also.) The lower base plate 1-d of the double base plate 1-w and the base are directly connected to the base (FIGS. 27 to 28 are examples thereof) or the lower support member 2 and the base are joined. Is done.
Then, the center part on the upper support member 3-a or the upper support member 3-b directly above the upper support member 3-b, in which the four base isolation plates are installed (four balls of the base support ( Rolling element) The central part of the plane formed by the center of 1-b, which is preferably the central part, but deviates from the central part within the range where there is no hindrance in terms of manufacturing and construction, and in terms of load transmission. In some cases, the upper support material joint portion 3-c is installed (FIG. 44 (a)).
Here, the upper support material 3-a is composed of four double base isolation plates 1-w, and the load from the base 8 is four balls (rolling elements) 1-b. The size and shape of the upper two base isolation plates 1-u of the four double base isolation plates 1-w can be joined to each other. The size and shape of the quadrangle formed by the center of the four balls (rolling elements) 1-b of the seismic isolation plate 1-w are required.
In addition, since the upper support member 3-b is for transmitting the load from the base isolation frame 8 to the four balls (rolling elements) 1-b, the double base isolation plate base isolation bearing 1 The size and shape of the quadrangle formed by the center of the four balls (rolling elements) 1-b of -w are required.
Joining the upper support material 3-a and four double base isolation plates 1-w to the upper base plate 1-u and reinforcing the upper support material 3-a directly above the upper support material The joining with the material 3-b is not particularly limited, such as bolt joining, welding joining, joining with an adhesive, and the like. Moreover, it may be integral with cast steel etc.
Furthermore, the upper support material joint part 3-c is for transmitting the load from the base isolation rack 8 evenly to the four balls (rolling elements) 1-b. It must be installed in the center of a quadrangle formed by the center of four 1-w balls (rolling elements) 1-b and must have a size and shape that can transmit the load from the seismic isolation rack 8.
However, a part (peripheral part) of the upper support material joint portion 3-c overlaps with the position of the ball (rolling element), and the upper support material 3-a and the upper support material 3 just above the upper support material at the lower part thereof. As a result of the combined effect with -b, the rigidity between the load point (the center point of the upper support joint portion 3-c) and the support point (ball (rolling element)) is increased, and the load is concentrated on the ball. It is desirable not to make it larger (wider) than necessary.
The upper support material beam portion 3-d is installed on the upper support material joint portion 3-c of each of the four locations in an X shape so as to straddle the upper support material joint portion 3-c. Be joined.
The joint between the upper support member 3-b and the upper support joint part 3-c, and the joint between the upper support joint part 3-c and the upper support beam part 3-d are bolt joints and weld joints. There is no particular limitation such as bonding with an adhesive. Moreover, it may be integral with cast steel etc.

Further, a pin support (ball seat) 4 is installed at the center of the upper support beam portion 3-d, and the seismic isolation rack 8 is installed on the pin support (ball seat) 4 and joined thereto. The base isolation frame 8 supports the base isolation structure (building) D.
With the above configuration, the load via the base isolation frame 8 of the base isolation structure (building) D is evenly transmitted to each double base isolation base isolation base 1-w.
If the area where the pin bearing (ball seat) 4 is placed is sufficiently small compared to the total area of the seismic isolation bearing and the bending is not transmitted so much, instead of the pin bearing (ball seat) 4, the upper part of the plate The support material joint portion 3-c may be used. Also, even when the upper support joint portion 3-c is installed, since the bending is not transmitted when the pin support (ball seat) 4 is placed, more uniform load can be obtained in the seismic isolation support. -c may be replaced with a pin support (ball seat) 4.
In this example, the example of the double seismic isolation plate-isolated bearing 1-w is given as the seismic isolation bearing, but other rolling seismic isolation bearings are possible as well, but the area is compact. Considering this, the double seismic isolation plate 1-w is advantageous. In particular, the double seismic isolation plate 1-w with the mortar and spherical gradient is particularly advantageous.

This is an example, and a set of four seismic isolation bearings arranged side by side in a 2 × 2 (equal) grid and integrated with each other, a load point (upper support joint portion 3-c) and a support point (ball ( It shows the positional relationship with the rolling element)).
In the embodiment of FIGS. 24 to 26 (16 double-isolated plate base isolation bearings are arranged), the force acting on the four balls (rolling elements) 1-b is applied to one upper support joint portion 3-c. The upper support member directly above the upper support member 3-a and the upper support member directly above the reinforcing member 3 are flat members supported by the four supporting points (four balls (rolling elements) 1-b). Since it acts as a concentrated load at the central part of -b, when the force becomes large, the plate thickness of the upper support material 3-a and the upper support material 3-b directly increases.
FIG. 44 (b) shows that four balls (rolling elements) are divided into two groups of two, and each center part (center point) of the straight lines connecting the centers of the two balls (rolling elements). Although it is desirable, it may be displaced from the center point within the range where there is no hindrance in terms of manufacturing and construction, and in terms of load transmission). By providing joints at two locations that are almost line-symmetrical and installing the upper support joint 3-c, the load from the seismic isolation rack 8 is evenly transmitted to the four balls (rolling elements). At the same time, by dispersing one concentrated load into two, it is an embodiment that can reduce the plate thickness of the upper support material 3-a and the upper support material 3-b.

FIGS. 29 and 30 show the invention relating to the seismic isolation bearing (16 seismic isolation plates 16 seismic isolation arrangement) consisting of 16 balls (rolling elements) according to claim 1, claim 9 or claim 16. This is an example. 29A is a sectional view, FIG. 29B is a plan view, and FIG. 30 is a perspective view.
FIGS. 29 and 30 show the upper support material 3-a and the upper support material immediately above in the embodiment shown in FIGS. 24 to 26 and FIG. 44 (b) (16 bases for double seismic isolation plates). In order to reduce the plate thickness of the reinforcing material 3-b, it is the most effective (the thickness of the upper supporting material 3-a and the upper supporting material 3-b can be made the thinnest). is there.
Two sets of four balls (rolling elements) 1-b on the upper support material 3-a or the upper support material 3-b directly above the upper support material 3-a, which has four double base isolation plates The center part of the straight line connecting the centers of the two balls (rolling elements) 1-b in the ball (rolling element) 1-b (preferably the center point, but also due to the manufacturing and construction, the load This is an example in which the upper support joint portions 3-c are respectively installed in a range where there is no hindrance in terms of transmission, which may deviate from the center point (FIG. 44 (c)).
A member that can be joined to each of the eight upper support joints 3-c is provided at the tip of the four X-shaped members on the upper support joints 3-c in each of the eight places. The upper support material beam portion 3-d thus formed is installed and joined to each of the upper support material joint portions 3-c.
In the embodiment shown in FIGS. 24 to 26, the force acting on the four balls (rolling elements) 1-b acts on one upper support joint portion 3-c, and the force is applied to the four fulcrums (4 Since it acts as a concentrated load at the center of the upper support material 3-a and the upper support material 3-b, which are flat members supported by two balls (rolling elements) 1-b), When the force becomes large, the plate thickness of the upper support material 3-a and the upper support material 3-b is also increased.
On the other hand, in the embodiment of FIGS. 29 and 30, the force acting on the two balls (rolling elements) 1-b acts on the one upper support material joint portion 3-c, and the force reduced by half is Four support points (balls) on the upper support material 3-a and the upper support material 3-b, which are flat members supported by the four support points (ball (rolling element) 1-b). (Rolling elements) 1-b) will be distributed and act on the center points of the opposing straight lines, and the load will be applied evenly to the four balls (rolling elements) 1-b. Compared with the embodiment of FIGS. 24 to 26, the upper support is further improved in the embodiment of FIG. 44 (b) because the support joint portion 3-c) and the support point (ball (rolling element)) are the closest distance. The plate thickness of the material directly above the material 3-a and the upper support material directly above the reinforcing material 3-b can be reduced most.

FIGS. 31 to 33 show the invention relating to the seismic isolation bearing (six seismic isolation base seismic isolation six arrangements) composed of six balls (rolling elements) according to claim 1, claim 10 or claim 16. This is an example. 31 is a cross-sectional view, FIG. 32 is a perspective view, and FIG. 33 is an exploded perspective view.
Six of the double seismic isolation plates 1-w are arranged in a 2x3 (equal) grid and are integrated into a single set. In some cases).
The six groups of double seismic isolation plates 1-w with a single ball (rolling element) arranged in this way consisted of an upper seismic isolation plate and a lower seismic isolation plate, respectively. In some cases, the seismic isolation bearing has six balls (rolling elements) (in this case, if the seismic isolation tray of this seismic isolation bearing is sufficiently rigid, Either the upper support material 3-a or the both may be unnecessary).
The upper support material 3-a and the upper support material 3-b, if necessary, are installed on the upper part of the six base-isolated plate 1-w. The reinforcing material 3-b directly above the material is not necessary if the upper supporting material 3-a has sufficient rigidity. In addition, a lower support member 2 is installed on the lower part of the six lower base isolation plates 1-d of the double base isolation plate 1-w as needed (the lower support member 2 may not be provided). . The lower base plate 1-d of the double base plate 1-w and the foundation are joined directly, or the lower support member 2 and the base are joined.
And the following two points on the upper support material 3-a or the upper support material 3-b directly above the upper support material 3-b where the six base isolation plates are installed. -c is installed.
Here, the upper support material 3-a is composed of six double base isolation plates 1-w, and the load from the base 8 is four balls (rolling elements) 1-b. The size and shape of the upper two base isolation plates 1-u of the six double base isolation plates 1-w can be joined to each other. The size and shape of the quadrangle formed by the center of the six balls (rolling elements) 1-b of the base isolation plate 1-w are required.
In addition, since the upper support member 3-b is for transmitting the load from the base isolation rack 8 to the six balls (rolling elements) 1-b, the double base isolation plate base isolation bearing 1 The size and shape of the quadrangle formed by the center of the six balls (rolling elements) 1-b of -w are required.
Joining the upper support material 3-a and the six double base isolation plates 1-w to the upper base plate 1-u and reinforcing the upper support material 3-a directly above the upper support material The joining with the material 3-b is not particularly limited, such as bolt joining, welding joining, and joining with an adhesive. Moreover, it may be integral with cast steel etc.
Furthermore, the upper support material joint part 3-c is for transmitting the load from the base isolation rack 8 evenly to the six balls (rolling elements) 1-b. It is necessary to have a size and shape that can be installed at a position and that can transmit the load from the base isolation rack 8.
However, a part (peripheral part) of the upper support material joint portion 3-c overlaps with the position of the ball (rolling element), and the upper support material 3-a and the upper support material 3 just above the upper support material at the lower part thereof. As a result of the combined effect with -b, the rigidity between the load point (the center point of the upper support joint portion 3-c) and the support point (ball (rolling element)) is increased, and the load is concentrated on the ball. It is desirable not to make it larger (wider) than necessary.
The upper support material beam portion 3-d is installed on the upper support material joint portion 3-c in two places in a straddling manner, and is joined to each of the upper support material joint portions 3-c.
The joint between the upper support member 3-b and the upper support joint part 3-c, and the joint between the upper support joint part 3-c and the upper support beam part 3-d are bolt joints and weld joints. There is no particular limitation such as bonding with an adhesive. Moreover, it may be integral with cast steel etc.

Further, a pin support (ball seat) 4 is installed at the center of the upper support beam portion 3-d, and the seismic isolation rack 8 is installed on the pin support (ball seat) 4 and joined thereto. The base isolation frame 8 supports the base isolation structure (building) D.
With the above configuration, the load via the base isolation frame 8 of the base isolation structure (building) D is evenly transmitted to each double base isolation base isolation base 1-w.
If the area where the pin bearing (ball seat) 4 is placed is sufficiently small compared to the total area of the seismic isolation bearing and the bending is not transmitted so much, instead of the pin bearing (ball seat) 4, the upper part of the plate The support material joint portion 3-c may be used. Also, even when the upper support joint portion 3-c is installed, since the bending is not transmitted when the pin support (ball seat) 4 is placed, more uniform load can be obtained in the seismic isolation support. -c may be replaced with a pin support (ball seat) 4.
In this example, the example of the double seismic isolation plate-isolated bearing 1-w is given as the seismic isolation bearing, but other rolling seismic isolation bearings are possible as well, but the area is compact. Considering this, the double seismic isolation plate 1-w is advantageous. In particular, the double seismic isolation plate 1-w with the mortar and spherical gradient is particularly advantageous.
* The two sides of the upper support material joint 3-c are formed by the center of the six balls (rolling elements) 1-b of the seismic isolation bearing, and the long side is 2 × L (L is the ball 1-b. On the center line that is almost parallel to the long side of the short side (not necessarily completely on the center line) in the rectangle with the center-to-center spacing (not necessarily completely on the center line) Within the range, there may be a deviation from the center line), the distance of approximately 0.226 × L from both ends of the long side (not necessarily strictly 0.226 × L, depending on the manufacturing and construction fit, Further, the upper support joint portion 3-c is installed in the vicinity of two positions on the inner side within a range where there is no hindrance in terms of load transmission (which may deviate from a distance of 0.226 × L). FIG. 45 (a) shows the position of the upper support joint portion 3-c, and the distance 0.226 × L from both ends of the long side is a value obtained by solving the following cubic equation. is there.

34 to 36, in the embodiment shown in FIGS. 31 to 33 (six seismic isolation plates with 6 base isolation plates), a thick plate is used instead of a section steel for the upper support beam portion 3-d. It is an example. 34 is a sectional view, FIG. 35 is a perspective view, and FIG. 36 is an exploded perspective view.
In this case, the height of the upper support beam 3-d can be reduced, and as a result, the depth of the foundation (root cutting depth) becomes shallow, reducing costs in earthwork and foundation work. can do. Note that the shape of the upper support beam portion 3-d is not limited to a cross-sectional shape such as a shape steel, a steel plate, or a steel bar as long as it does not interfere with load transmission.

This is an example, and a set of six seismic isolation bearings arranged in a 2 × 3 (equal) grid and integrated with each other, a load point (upper support joint portion 3-c) and a support point (ball ( It shows the positional relationship with the rolling elements)).
In the embodiment of FIG. 31 to FIG. 33 (six base isolation plate base isolation bearing arrangement), the force acting on three balls (rolling elements) 1-b is applied to one upper support joint portion 3-c. The upper support material just above the upper support material 3-a and the upper support material just above the reinforcing material 3 are flat members supported by six supporting points (six balls (rolling elements) 1-b). Since it acts as two concentrated loads on -b, when the force becomes large, the plate thickness of the upper support material 3-a and the upper support material 3-b directly increases.
FIG. 45 (b) shows that each of the two concentrated loads in the embodiment of FIGS. 31 to 33 has a long side of 2 × L (L is the center of the six balls (rolling elements) of the seismic isolation bearing). In the rectangle of the center of the ball), it is parallel to the two short sides and is a distance of about 0.226 × L from the short side (it is not necessarily strictly the distance of 0.226 × L. In addition, within a range where there is no hindrance in terms of load transmission, it may be displaced from the distance of 0.226 × L). By dispersing them at two locations and installing the upper support joint 3-c, the load from the seismic isolation rack 8 is evenly transmitted to the six balls (rolling elements) and at the same time two concentrated By dispersing the load into four parts, the upper support material 3-a and the upper An embodiment in which it is possible to reduce the thickness of the support immediately above reinforcing material 3-b.
