Abstract

PURPOSE:To raise the isolating action of earthquake by a method in which the lower end of an elastic part connected to the inside end of the tapered recession of a slide plate is connected to the floor base in a slidable manner within a regulated range and also the downside of the slide plate is likewise connected to a regulative disc board. CONSTITUTION:In case where horizontal vibration is mainly occurred in a comparatively small earthquake, the lower end of an elastic part 3 connected to the tapered recession 2 of a slide plate 1 fixed to the downside of floor panels 12 is slid on the upside of the floor base 11 according to the vibration degree. As the vibration increases, the part 3 is contacted with the regulative short cylinder 10 of a slide regulative disc board 8 to cause an isolating action of earthquake by the elastic expanding-contracting actions of the part 3. When the plate 1 comes into contact with the board 8, the plate 1 and the board 8 are mutually slid during the vibration. In the vertical vibration, the isolating action of earthquake can be secured by the action of the part 3 in the aperture between the downside of the plate 1 and the board 8. The damping rate of vibration can thus be raised.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a seismic isolation system that supports foundations of various buildings, floors within buildings, and various devices or articles while protecting them from earthquakes and other vibrations. It is related to the device.

[Conventional technology] Conventional seismic isolation devices basically support the floor by
It has been proposed that legs are formed at the bottom of a plate and rubber is attached to the lower ends of these legs.

There are also structures in which elastic material is placed between the foundation and the structure as a seismic isolation device.

No seismic isolation device is proposed to support the foundation.

[Problems to be solved by the invention] The former is integrated with the floor and cannot be freely used for seismic isolation of various objects. Furthermore, due to its mechanism, it cannot sufficiently cope with horizontal shaking.

Similarly, the latter cannot be freely applied to various objects.

The present invention can easily support various seismically isolated objects such as the floor of a building, support the foundation of the building itself, or other various articles or devices, and provide advanced seismic isolation. The purpose is to provide a device that can give an effect.

[Means for Solving the Problems] The gist of the configuration of the present invention is that a tapered recess is formed in the center of the slide plate, and the diameter becomes smaller toward the inner end, and the depth of the tapered recess is at least greater than the depth of the tapered recess. A long elastic column is formed, one end of the elastic column is fixedly connected to the inner end of the tapered recess of the slide plate, and the other end is fixedly connected to a connecting means with the object to be connected, and the other is connected fixedly. A slide regulating means is constructed on the other side, and the slide plate is joined to be able to slide freely within the regulating range, and a reinforcing means is constructed on the back side of the sliding plate around the protrusion formed on the back surface of the tapered recess. It is a seismic device.

The slide plate can freely adopt various shapes such as a square, a polygon, or a circle when viewed from the plane. However, a circular shape that is uniform in all horizontal directions is most suitable.

Further, the slide plate may be formed of plastic or metal depending on the weight of the object to be supported.

The surface of the slide plate is configured to be a smooth surface. This can be realized with any arbitrary configuration.6 For example, it can be configured by coating the surface with a tetrafluoroethylene resin.

The opening angle of the tapered recess is preferably determined in consideration of how much amplitude in the horizontal direction can be tolerated during an earthquake or the like.

Preferably, the outer end of the elastic column will not easily come into contact with the opening end of the tapered recess when the upper or lower end of the elastic column swings in the horizontal direction in the expected largest earthquake. is good.

As described above, the coupling between one end of the elastic column and the inner end of the tapered recess of the slide plate and the coupling means for coupling the other end of the elastic column to the object to be coupled are performed by fixing one end of the elastic column to the inner end of the tapered recess of the slide plate. In the case of a flexible joint, the other side should be a slidable joint.

That is, for example, the object to be connected is a subfloor, and the means for connecting with the subfloor is a plate member facing the slide plate,
In the case where the plate member is provided with a slide regulating means and one end of the elastic column is slidably joined within the regulating means, 1, for example, a limiting hole is bored in the plate member as the regulating means. When the plate member is joined to the floor subfloor, one end of the elastic column may be slidably joined to the upper surface of the floor base whose bottom surface is formed in the defined hole. The plate member may, for example, be configured in the shape of a disk with a larger diameter than the slide plate, the limiting hole may be bored in the center thereof, and a short cylindrical upright portion may be formed around the circumferential edge of the limiting hole. In this way, even if the horizontal vibration becomes large, the sliding movement of one end of the elastic column can be reliably regulated within the defined hole.

On the other hand, in this case, the other end of the elastic column is bonded and fixed to the inner end of the tapered recess of the slide plate. For example, a coupling cylinder is provided protrudingly at the inner end of the tapered recess, and the other end of the elastic column is inserted into this and fixed with an adhesive or the like.

Further, the coupling means for coupling to the coupling object may be composed of an elastic plate that can be combined with a plurality of slide plates. For example, as a regulating means to be constructed in this, a limiting hole is formed at the center of each position facing the plurality of slide plates. It is optional whether or not to form a short cylindrical rise on the edge of this limiting hole.

The method of connection to one end of the elastic column in this case is the same as in the previous example. The method of coupling the other end of the elastic column to the inner end of the tapered recess of the slide plate is also similar.

When the object to be connected above is a subfloor.

The means for coupling with this is the surface of the coupling object itself, i.e.
In the case of the above example, it is assumed that the elastic column is a subfloor surface, and one end of the elastic column is directly fixed on the upper surface thereof, or a slide regulating means is configured thereon and is slidably joined thereto.

As the slide regulating means, a circular limiting recess is formed on the surface of the object to be joined, in the above example, the upper surface of the flooring, and one end of the elastic column is slidably joined to the bottom surface of the recess.

Further, for example, when one end of the elastic column is slidably joined to the inner end of the tapered recess of the slide plate, a slide regulating means is configured at the inner end of the tapered recess.

As the slide regulating means, for example, a circular limiting recess is formed at the center of the inner end of the tapered recess. One end of the elastic column is slidably joined to the bottom of the elastic column. Naturally, the diameter of the limiting recess is made to be sufficiently larger than the diameter of the end of the elastic column that joins the bottom of the limiting recess. More theoretically, the diameter should be within a range that allows the end of the elastic column to slide.

Further, the slide regulating means may be composed of, for example, a large-diameter recess formed at the center of the inner end of the tapered recess and a small-diameter recess formed further at the center.

In this case, a small-diameter column portion slightly longer than the depth of the small-diameter concave portion is formed at one end of the elastic column, and the tip of the small-diameter column portion is slidably joined to the bottom surface of the small-diameter concave portion.

In the case of the above-mentioned two sides, the other end of the elastic column is fixed to a connecting means to be connected to the object to be connected.For example, if the object to be connected is a subfloor, it is fixed to the surface thereof.

By the way, the elastic column is made of, for example, a cylindrical rubber member. The material of the above-mentioned rubber member is not limited to a specific one, but it is preferable to mold it from synthetic rubber with appropriate elasticity.The material of the rubber member is prepared in various elasticity in appropriate stages, and the object to be supported by this material is prepared. It is appropriate to use them according to their weight.

In addition, when the elastic column is set on the slide plate,
In the case of a small load, for example, it is appropriate to configure the length and elasticity so that there is a slight gap between the sliding plate and the object to be connected or the connection means for the object to be connected. be. Alternatively, even in the case of a fairly large load, the length can be determined so that there is a slight gap at the above position.

The reinforcing means can be constituted by, for example, ribs that extend radially from the outer periphery of a protrusion that stands up from the back surface of the slide plate and protrudes rearward as the tapered recess is formed. If necessary, a plurality of concentric annular ribs centered on the protrusion can be added to the above-mentioned ribs.

[Function] Since the present invention is configured as described above, a plurality of them can be used to support the internal floors of various buildings,
Alternatively, it can be used to support the foundation of a building itself to attenuate earthquakes and other shaking, thereby protecting the objects mentioned above.

For example, when supporting a floor with this seismic isolation device, either the protrusion side or the open end side of the slide plate is connected to the lower surface of the floor member.

Taking the former case as an example, first, the upper surface of the protrusion and the upper end of the reinforcing means, for example, the rib, are connected to the lower surface of the board constituting the base plate of the floor member. Adhesion or other fixing means may be applied as necessary.

Each end of the elastic column is fixed to either the inner end of the tapered recess of the slide plate or to the flooring, and the other end is provided with a slide regulating means so that the elastic column can slide freely within that range.

For example, a coupling cylinder is configured at the inner end of the tapered recess of the slide plate, and a plate member or an elastic plate is configured to be coupled to the subfloor,
Alternatively, if a limited recess is formed on the upper surface of the subfloor,
The upper end of the elastic column is inserted into and fixed to the coupling cylinder protruding from the inner end of the tapered recess of the slide plate, and the lower end is slidably joined to the bottom surface of the limited hole of the plate member or the elastic plate. do. Alternatively, it is slidably joined to the bottom surface of the limiting recess.

By performing the above steps at appropriate intervals, floor members are placed on the entire subfloor.

In this way, the floor members are supported by the seismic isolation device of the present invention at appropriate intervals. A desired decorative material is applied to the upper surface of the floor member to complete the floor. Note that it is necessary to leave a slight gap at the outer edge of the area where the floor member is installed, that is, at a position adjacent to a wall surface, etc., and to arrange a cushion member in that gap.

Therefore, the seismic isolation device of the present invention can be installed extremely easily at the required position.

In addition, when the floor is supported by this seismic isolation device, even if vibrations are transmitted to the subfloor due to an earthquake, etc.
Seismic isolation can be performed very efficiently.

In the case of a relatively small earthquake, the horizontal shaking is
In the case of the main shaking, the lower end of the elastic column, together with the slide plate, relatively slides on the bottom surface of the limiting hole or limiting recess in accordance with the shaking, so it is possible to obtain an almost complete seismic isolation effect. . Further, when the swing becomes large and the lower end of the elastic column comes into contact with the edge of the limiting hole or the limiting recess due to its sliding movement, the lower end of the elastic column engages with the edge of the limiting hole, etc. Therefore, relative rocking of the slide plate exceeding this range can be performed within the range of elastic expansion and contraction of the elastic column.

In this way, when the swing is small, an effective seismic isolation effect can be achieved by the sliding movement of the lower end of the elastic column, and when it is large, the elastic stretchability of the elastic column can provide an effective seismic isolation effect in a range exceeding the slide restriction range.

In addition, in order to prevent vibrations in the vertical direction, by configuring the elastic columns with a sufficiently long length so that the slide plate and the flooring do not come into contact with each other, the elastic expansion and contraction action of the elastic columns in the axial direction is activated. Ensure seismic action. Alternatively, if the coupling target/coupling means is composed of an elastic plate, even if the slide plate is in contact with it, the seismic isolation effect can be ensured due to its elasticity.

By the way, when supporting the foundation of a building with the seismic isolation device of the present invention, for example, the corresponding area is dug, gravel is spread, compacted, and a concrete base is poured on top of it. Then, a plurality of seismic isolation devices of the present invention are arranged vertically and horizontally at appropriate intervals. This arrangement can be done with either the protrusion side or the open end side of the tapered recess upward, as described above.Then, place the concrete plates divided into an appropriate number on the seismic isolation device. Place it. That is, as in the case described above, 1
For example, a concrete plate is supported by a protrusion behind the slide plate, and the plate member etc. is placed on the base concrete,
In this way, one end of the elastic column is fixed to the inner end of the tapered recess of the slide plate, and the other end is slidably joined onto the base concrete in a defined hole of the plate member, etc. . The concrete plate mentioned above will be buried below the ground line. Furthermore, a cushion member is provided around the concrete plate in order to cut the edge from the surrounding ground.

After this, the foundation will be constructed on the concrete plate.

Furthermore, in the above case, the concrete plate may be omitted and the separately formed foundation concrete may be directly supported by the seismic isolation device.

In the above cases, in addition to constructing a slide plate of equivalent strength and using an elastic column having the necessary elasticity and strength,
Basically, it is no different from supporting the floor.

The usage of the above foundations and foundation concrete is the same as that of general foundations.

In this way, a foundation with a seismic isolation effect can be easily obtained.

[Example] The present invention will be described in detail below based on the drawings.

First, a first embodiment of the present invention will be described based on FIGS. 1 to 3.

As shown in FIGS. 1 to 3, a tapered recess 2 is formed in the center of the slide plate 1 and expands toward the open end. The slide plate l has a circular shape when viewed from the plane or the bottom, and the tapered recess 2 is also circular when viewed from the same direction, that is,
Constructed in a conical shape with an outer edge.

At the inner end of the tapered recess 2, a coupling cylinder 4, into which the upper end of an elastic column 3 to be described later is inserted, is suspended in the center thereof, and an elastic column is inserted midway through the inner circumference of the coupling cylinder 4. 3 constitutes a locking protrusion 5 that performs a locking action.

Further, on the back surface ll1 (upper surface side) of the slide plate 1, there is a 60° ridge around the conical protrusion 6 that protrudes due to the configuration of the tapered recess 2, as shown in FIGS. 1 and 2.
The ribs 7.7 extend in the radial direction to the peripheral edge of the slide plate l at angular intervals of . These ribs 7.7...
・ stands up from the back (upper surface) of the slide plate l, and its height is the same as the upper surface of the conical protrusion 6.

Further, the front (lower surface) of the slide [1 is faced with a regulating disk 8 having a larger diameter. A circular limiting hole 9 for regulating the sliding range of the lower end of the elastic column 3 is bored in the center of the regulating disc 8, and a short regulating cylinder 10 is raised at the edge thereof.

The upper surface of the regulating disc 8 and the lower surface of the slide plate 1 facing the regulating disc 8 are each formed into a smooth surface.

As shown in FIG. 1, the elastic column 3 is a roughly cylindrical member molded from chloroprene-based synthetic rubber. Its elasticity and stiffness were determined in this example as appropriate for the support of the floorboard. The length of the elastic column 3 should be determined as described below (when connected to the slide plate 1, there will be a gap between the bottom surface of the slide plate 1 and the top surface of the regulation disk 8. The bottom surface of the elastic column 3 shall have a smooth surface.

As shown in FIG. 1, the elastic column 3 has its upper end inserted into the coupling cylinder 4 which projects from the inner end of the tapered recess 2 of the slide plate 1. The upper end of the elastic column 3 is
By locking its outer periphery with the locking protrusion 5, it is fixed in the coupling cylinder 4.

Since this embodiment has the above structure, it is suitable for use in supporting the floors of various buildings while attenuating earthquakes and other shaking (of course, other uses are also possible). It can be easily adapted to any type of floor, and its installation is also simple.

First, a flat subfloor 11 is constructed in the area to be constructed as a floor, as in the general case. The floor that adopts this seismic isolation device has the corresponding number of floor members 12 on the above-mentioned floor base ll.
．． 12... is stretched, and decorative material 13.13... is placed on top of it.
・ shall be constructed by pasting on each of the above floor members 12.1.
2... are each supported at several locations by the seismic isolation device placed on the subfloor 11.

The details are as follows.

As shown in FIG. 1, the upper surface of the conical protrusion 6 and the upper end of the rib 7 of the slide plate l of the seismic isolation device are joined to the lower surface of the floor member 12, and both are fixed with adhesive. Further, the regulation disc 8 is placed on the subfloor ll with its center aligned with the slide plate 1. This is fixed onto the floor base 11 with adhesive or the like. Then, the lower end of the elastic column 3 is connected to the limiting hole 9 of the regulating disk 8.
It is inserted into the interior and is slidably joined to the upper surface of the floor base 11 that appears like the bottom surface.

At this time, as described above, since the elastic column 3 is configured to be long enough, the lower surface of the slide plate l and the above-mentioned restriction circle 12ii
There is a gap between the upper surface of
There may be gaps.

In addition, the above-mentioned floor members 12.12... are the outer edge of the installation area,
That is, a certain width from the peripheral wall is left uninstalled, and the cushion member is disposed at this position.

After arranging the floor members 12, 12,... in the entire area in this way, the decorative materials 13,13-, are pasted thereon (the decorative materials 13,13... are preliminarily applied to the floor members 12,12-,・It goes without saying that you can paste it on top.)

Accordingly, the floor members 12, 12, . . . are arranged in a seismically isolated state on the floor base 11 by the plurality of seismic isolation devices, and a floor is easily constructed in a predetermined area.

The seismic isolation device of this embodiment is as described above, and as described above, it can be installed extremely easily at the required position.

In addition, by this seismic isolation device, the floor members 12.12
..., it is possible to perform a seismic isolation effect very efficiently even when vibrations are transmitted to the subfloor 11 due to an earthquake or the like.

In the case of a relatively small earthquake, where the main vibration component is horizontal shaking, the lower end of the first elastic column 3 will move toward the bottom surface of the limiting hole 9 of the regulating disk 8, i.e., in response to the shaking. ,
By relatively sliding on the upper surface of the subfloor 11 shown here, the slide ml and other members can obtain an almost complete seismic isolation effect.

In addition, if the swinging becomes large and the lower end of the elastic column 3 comes into contact with the regulating short tube 10 raised up on the edge of the limiting hole 9, the elastic column The lower end of the elastic column 3 engages with the short regulating tube lO, and the slide plate I and the other members can be swung within the elastic range of the elastic column 3. In this case, the elastic column 3 falls diagonally, so the slide plate 1
and the regulating disk 8 become narrow (or come into contact with each other. If they come into contact, they will slide against each other during the above-mentioned swinging. In this way, in a small range of swinging, the elasticity The sliding swing of the lower end of the column 3 can provide an effective seismic isolation effect due to the elastic extensibility of the elastic column 3 if it is large.

In addition, with respect to vibrations in the vertical direction, a gap is provided between the lower surface of the slide plate l and the regulating disc 8 so that they do not come into contact with each other, so that the elastic expansion and contraction action of the elastic column 3 in the axial direction Seismic isolation can be ensured.

Next, a second embodiment of the present invention will be described based on FIGS. 4 and 5. Most of this is similar to the first embodiment, so only the different parts will be explained.

As shown in FIG. 4, this embodiment differs only in the elastic regulating plate 28 disposed on the subfloor 31. As shown in FIG. 5, this elastic regulating plate 28 is constructed so that nine slide plates 21, 21... are installed at equal intervals on it, and nine limiting holes are arranged vertically and horizontally. 29.29... is drilled. In addition, this elastic regulating plate 28 is a regulating disc 8
The thickness is more than twice that of the original one.

In the figure, 22 is a tapered recess, 24 is a coupling cylinder, and 25 is a locking projection.

Since this embodiment is constructed as described above, it is suitable for use in supporting floors and the like of various buildings while attenuating earthquakes and other shaking, similar to the first embodiment.

Regarding usage, only the parts that are different from the first embodiment will be explained.

First, a required number of the elastic regulating plates 28, 28, . . . are arranged on the subfloor 31 in the installation area.

After doing so, insert the slide plates 21, 21, . . . into each of the limiting holes 29, 29, .
- Insert the lower ends of the elastic columns 23, 23, etc., which are set in the same manner as in the first embodiment. In this example, the thickness of the elastic regulating plates 28, 28... is configured to be more than twice that of the regulating disc 8 as described above, so that the slide plate 21
．． The lower surface of 21... and the elastic regulating plate 28, 281...
The upper surfaces will be slidably joined to each other, and the lower ends of the elastic columns 23,23... 3
It does not mean that it is bonded to the top surface of 1.

In this way, slide the above into all the limiting holes 29.29...
1. After setting 21 etc., each slide plate 2
1.21... are fixed to the upper surfaces of the conical protrusions 26, 26... and the upper ends of the ribs 27, 27... and the floor members 32.
32... is arranged. A decorative material 33 is pasted on the upper surface.

In this case as well, a seismic isolation effect can be obtained by the same action as in the first embodiment.

Horizontal seismic isolation is achieved by slide plate l, elasticity control plate 28
obtained by mutual sliding movement with. If the swinging becomes large and the lower end of the elastic column 23 comes into contact with the edge of the limiting hole 29, the lower end of the elastic column 23 will be locked here, so further swinging will be prevented. The elastic expansion and contraction action of the elastic column 23 also works.

In addition, when a large load is applied, the elastic regulating plate 2
8 contracts, and the lower end of the elastic column 23 also comes into contact with the flooring 31 exposed within the limiting hole 29. Therefore, during rocking, the lower end of the elastic column 23 also slides. In this way, it slides while fully supporting the load and generates a seismic isolation effect. If the vibration is larger than this, it is the same as described above.

In this way, for small horizontal swings, a seismic isolation effect is obtained by the sliding movement of the elastic regulating plate 28 and the slide plate 1, or in addition to this, by the sliding movement of the lower end of the elastic column 23, and for larger swings, the elastic A seismic isolation effect is obtained by the elastic expansion and contraction of the columns 23.

The vertical seismic isolation effect is achieved by the elastic regulating plate 28.28-.
can be obtained by the elasticity of the elastic column 23 and by the elasticity of the elastic column 23.

Finally, a third embodiment of the present invention will be described based on FIG.

As shown in FIG. 6, the slide plate 41 has a circular downwardly tapered recess 42 whose diameter gradually decreases toward the inner end, and a circular large-diameter recess 44 at the center of the inner end. Furthermore, a circular small-diameter recess 45 is formed in the center thereof. The lower surface of the slide plate 41 is configured to be a smooth surface.

Note that the small-diameter recess 45 is the small-diameter column portion 4 of the elastic column 43 described later.
The tip of No. 8 has an appropriate diameter so that it can slide freely in the event of a small earthquake.

Further, the back side (top side) of the slide @41 has a protrusion in accordance with the configuration of the tapered recess 42.

Ribs 47, 47 and 47 extend radially around the protruding conical protrusion 46 to the peripheral edge of the slide plate 41 at angular intervals of 60".
Configure... These ribs 47, 47, .

Furthermore, an elastic column 43 is provided with a small-diameter column portion 48 slightly longer than the depth of the small-diameter recess 45 at its upper end. The end portion of the small diameter column portion 48 is configured to have a smooth surface. Note that the elastic column 4
3 has a length determined so that its lower end slightly protrudes from the lower end of the slide plate 41 when it is set on the slide plate 41 as will be described later. The elastic column 43 is made of chloroprene-based synthetic rubber, and its elasticity and rigidity are determined to be suitable for supporting the floorboard in this example as well.

The upper end of the small-diameter column portion 48 of the elastic column 43 is slidably joined to the inner end of the small-diameter concave portion 45 of the slide plate 41 .

Since this embodiment is constructed as described above, it is suitable for use in supporting the floors and other parts of various buildings while attenuating earthquakes and other shaking, similar to the first and second embodiments. be.

First, a flat subfloor 51 is constructed in a target area that constitutes a floor.

After doing so, the seismic isolation devices are sequentially arranged on the underfloor 51 at appropriate intervals. Each seismic isolation device.

As shown in FIG. 6, the lower end of the elastic column 43 only needs to be joined to the floor base 51.
Since it is made of rubber, it has a very high coefficient of friction, so if it is set up as described above, it will not move even if an earthquake occurs.

Floor members 52, 52... are placed on these seismic isolation devices. The floor members 52, 52... are fixed on the seismic isolation device by joining their lower surfaces to the upper surfaces of the conical projections 46 of the slide plate 41 and the upper ends of the ribs 47, and bonding them with adhesive.

In this way, the floor members 52, 52... are supported by the seismic isolation device.

By the way, the floor members 52, 52, . . . leave a portion not to be installed at the outer edge of the installation area, that is, a certain width from the peripheral wall, and the cushion member is provided at this position.

Note that after the floor members 52, 52, . . . are arranged in the entire area in this manner, the decorative materials 53, 53, .

Accordingly, the floor members 52, 52, . . . are arranged in a seismically isolated state on the floor base 51 by the plurality of seismic isolation devices, and a floor is easily constructed in a predetermined area.

In the event of an earthquake or the like, even if vibrations are transmitted to the subfloor 51, the vibrations are blocked by this seismic isolation device and hardly transmitted to the floor members 52, 52, etc. A.

As long as the vibration or rocking in the horizontal direction is small, the small diameter column 48 at the upper end of the elastic column 43 freely slides on the inner end of the small diameter recess 45 of the slide plate 41, so the vibration is almost completely blocked. can do.

When the limit is exceeded, a part of the outer periphery of the small-diameter column portion 48 at the upper end of the elastic column 43 engages with the edge of the small-diameter recess 45, and the elastic column 43 is then elastically expanded and contracted. Performs a seismic effect.

If horizontal vibration or rocking that exceeds this occurs, the elastic column 43 will fall down diagonally and the small-diameter recess 4
3 may be disengaged and move to the large diameter recess 44. In this case, the outer periphery of the elastic column 43 engages with the edge, and the elastic expansion and contraction of the column can provide a seismic isolation effect.

With respect to vibrations in the vertical direction, a seismic isolation effect can be achieved by elastic expansion and contraction of the elastic column 43 in the axial direction.

[Effects of the Invention] According to the present invention, it is possible to easily support the floor or foundation of a building, and when an earthquake or other vibration occurs, vibration or rocking is not caused to the members located above this. , it is possible to provide a seismic isolation effect that significantly blocks the earthquake. In particular, a seismic isolation device with an extremely high damping rate is obtained by combining both the seismic isolation effect due to vertical mutual sliding movement and the seismic isolation effect due to elastic expansion and contraction of the elastic column.
