Aspect A is advantageous in that the transition between the state in which the rolling resistance is generated and the state in which the frictional resistance is generated smoothly occurs, and the resistance change in the peripheral direction is smoothly generated.
Aspect B has an advantage in that a high frictional resistance is generated because the sliding member contacts the upper member and the lower member at four points in a state where the frictional resistance is generated.
In aspect C, in a state where frictional resistance is generated, if the swing is small, the sliding member comes into contact with the upper member and the lower member at three points, respectively. If the swing is large, the sliding member is connected to the upper member and the lower member. Since each contact is made at four points, there is an advantage in that the frictional resistance changes according to the magnitude of the shaking. In particular, the seismic isolation effect is excellent for long and narrow structures such as piers and long buildings.

  In the aspect A, the shape of the curved surface is not particularly limited, but it is preferable that the degree of inclination of the curved surface with respect to the horizontal direction increases from the top toward the peripheral edge (for example, sliding shown in FIGS. 19 to 21).

The shapes of the plurality of planes may be the same or different. Among these, it is preferable that they are the same.
The position of the plane may be from the peripheral edge of the top part to the peripheral edge part of the upper side surface, or may be present to any position between the peripheral edge part of the top part and the peripheral edge part of the upper side surface. When the flat surface exists from the periphery of the top portion to any position between the periphery of the top portion and the periphery of the upper side surface, the space between the position and the periphery can be formed by a curved surface. The position where the plane exists may be the same or different in the peripheral direction.
The number of radial directions of the plane may be one from the periphery of the top to the peripheral edge of the upper surface (for example, the sliding member 85 shown in FIGS. 12 to 14), or may be two or more. . When two or more planes are arranged in the radial direction from the periphery of the top portion to the peripheral portion of the upper side surface, it is preferable that the inclination with respect to the horizontal direction increases from the periphery of the top portion to the peripheral portion of the upper side surface. .
In the vicinity of the periphery of the top, the inclination of the plane with respect to the horizontal direction is preferably larger than the inclination of the curved surface with respect to the horizontal direction.

In the aspect C, the number of peripheral directions of the top plane is plural (two or more). Among these, 4 or more are preferable. When it is in the above range, the function can be exhibited uniformly with respect to shaking in all directions. Moreover, it is preferable that it is 12 or less. Manufacturing is easy in it being the said range. When the number of the peripheral direction of the plane around the top is four, the seismic isolation effect is excellent with respect to an elongated structure such as a bridge pier or an elongated building.
The shape of the top surfaces of the tops may be the same or different. Among these, it is preferable that they are the same.
The position of the plane around the top may be from the periphery of the top to the periphery of the upper side, or may be any position between the periphery of the top and the periphery of the upper side. Good. In the case where the flat surface exists from a peripheral edge of the top portion to a peripheral edge portion of the upper side surface, the curved surface can be formed from the position to the peripheral edge portion of the upper side surface. The position where the plane exists may be the same or different in the peripheral direction.
The number of radial directions of the plane may be one from the peripheral edge of the top to the peripheral edge of the upper surface (for example, the sliding member 86 shown in FIGS. 15 to 17), or may be two or more. . When two or more planes are arranged in the radial direction from the periphery of the top portion to the peripheral portion of the upper side surface, it is preferable that the inclination with respect to the horizontal direction increases from the periphery of the top portion to the peripheral portion of the upper side surface. .
In the vicinity of the periphery of the top, the inclination of the plane with respect to the horizontal direction is preferably larger than the inclination of the curved surface with respect to the horizontal direction.
In the vicinity of the periphery of the top portion, the number of peripheral directions of the top plane and the number of peripheral directions of the peripheral surface of the top portion may be different or the same. Among them, it is preferable that they are the same, and it is more preferable that the end of the top plane and the end of the plane around the top are in the same position.

In aspect D, the number of peripheral directions of the top plane is plural (two or more). Among these, 4 or more are preferable. When it is in the above range, the function can be exhibited uniformly with respect to shaking in all directions. Moreover, it is preferable that it is 12 or less.

The shape of the top surfaces of the tops may be the same or different. Among these, it is preferable that they are the same.
The plane need not be a complete plane. Especially, it is preferable that some chamfering is performed so that the inclination with respect to the horizontal direction increases from the top toward the peripheral edge (for example, the sliding member 88 shown in FIGS. 22 to 24).

The sliding member 85 is formed by the upper side surface 851 and the lower side surface 853 of the shape described above, and the circumferential side portion 855 existing therebetween.
In the sliding member 85, the concave portion 852 exists in the entire circumferential direction of the side portion 855. However, the present invention is not limited to this, and the concave portion may exist in a part of the circumferential direction of the side portion. It may be a thing without a recess.
When the concave portion is present in the entire circumferential direction of the side portion of the sliding member, it can be easily engaged with the protruding portions of the upper member and the lower member regardless of the orientation of the sliding member.
When the concave portion exists only in a part of the side portion of the sliding member in the circumferential direction, the strength in the vertical direction of the sliding member becomes higher because there is a portion that is not the concave portion.

  The sliding member 85 may be formed integrally, or may be formed by combining a plurality of members.

  The material of the sliding member 85 is not specifically limited, For example, a metal and ceramics are mentioned. Among these, from the viewpoint of durability, a metal is preferable, iron, an iron alloy, or an aluminum alloy is more preferable, and iron or an iron alloy is still more preferable.

  The upper side surface 851 and the lower side surface 853 of the sliding member 85 may be pre-coated or lubricated in order to make the sliding member 85 slide smoothly. This is one of the preferred embodiments.

  The sliding member 85 is sandwiched so that it can slide between the upper member 82 and the lower member 84. In this case, the protrusion 821 at the peripheral edge of the upper member 82 and the protrusion 841 at the peripheral edge of the lower member 84 can engage with the recess 852 of the side 855 of the sliding member 85. ing.

  As shown in FIG. 9, the seismic isolation unit 700 generally includes a sliding member 85 having an upper member 82 fixed to the upper structure 1 and a lower member 84 fixed to the foundation member 3, The contact surfaces 822 and 842 are installed so as to come into contact with each central portion (this position is referred to as “initial position”).

FIG. 18 is a schematic partial cross-sectional view of an example of the seismic isolation unit used in the floor panel assembly according to the first aspect of the present invention when shaking occurs.
When the lower member 84 is displaced to the right in the drawing as shown in FIG. 18 due to an earthquake or the like, force is transmitted to the sliding member 85 that is in contact with the lower member 84 to slide. The member 85 is inclined counterclockwise in the figure. Thus, the energy of shaking can be absorbed by the tilting of the sliding member 85.
In addition, the sliding member 85 slides while being sandwiched between the upper member 82 and the lower member 84 in a tilted state, a state where it is returning from its tilted state by its own weight, or a state where it has returned. This sliding causes a frictional force between the sliding member 85 and the upper member 82 and the lower member 84. Thus, the vibration energy can also be absorbed by the sliding member 85 sliding.
When the sliding movement of the sliding member 85 occurs and is displaced from the initial position, the contacting surface 822 of the upper member 82 with the sliding member 85 and the contacting surface of the lower member 84 with the sliding member 85 are the same. 842 is a concave surface, and the upper side surface 851 that contacts the upper member 82 and the lower side surface 853 that contacts the lower member 84 are both convex. Also caused by force. Therefore, in the seismic isolation unit 700, the efficiency of absorbing shaking energy is extremely high.
Such an operation is possible in all directions in the horizontal direction.

When the amplitude of the earthquake becomes extremely large, for example, as shown in FIG. 11, the lower member 84 fixed to the base member 83 is relatively illustrated with respect to the upper member 82 fixed to the upper structure 1. The left portion of the concave portion 852 of the side portion 855 of the sliding member 85 in the drawing is in a state shifted greatly to the middle right side, and the protruding portion 841 of the peripheral portion of the lower member 84 (the left portion in the drawing). The right portion in the drawing of the concave portion 852 of the side portion 855 of the sliding member 85 engages with the protruding portion 841 of the peripheral portion (the right portion in the drawing) of the upper member 82.
In this way, the lower member 84 is caught on the upper member 82 via the sliding member 85, and cannot be further shifted (to the right in the drawing) from this state. Therefore, the upper member 82 is not completely removed from the position corresponding to the lower member 84.
In addition, as shown in FIG. 11, when the lower member 84 receives a force that shifts to the right side in the drawing relative to the upper member 82, the sliding member 85 moves from the left side to the lower member. Since the force is applied to the right by 84 and the force is applied to the left by the upper member 82 from the right side, the overall state is slightly inclined from the lower left to the upper right. Therefore, the weight of the sliding member 85 causes a force to move the upper member 82 to the right side and the lower member 84 to the left side. This force is opposite to the direction shifted by the amplitude, that is, the upper member 82 and It works to restore the relative position of the lower member 84.
