Description of the Related Art In a seismic isolation structure of a structure, a vibration of the structure caused by an earthquake is interposed between a foundation and the structure by interposing a seismic isolation support that supports the structure movably in a horizontal direction. Reduced. As this seismic isolation support, a seismic isolation laminated rubber in which an elastic layer made of rubber or the like and a rigid plate layer made of a steel plate or the like are alternately laminated in multiple layers, or a structure is supported by a bearing and at the same time a spring and a damper are combined. There are known ones that absorb earthquake energy, or one that uses a sliding bearing and seismic isolation laminated rubber in combination.

ている。Generally, in this type of seismic isolation structure, the horizontal rigidity of the seismic isolation support is reduced, and the natural period of the vibration system including the structure and the seismic isolation support is made longer than the period of the horizontal vibration of the earthquake. This suppresses the vibration of the structure caused by the earthquake.

引張荷重に弱い免震積層ゴムが引張力を受ける可能性も
でてくる。However, setting the horizontal rigidity of the seismic isolation support to a low level also causes the structure to be easily displaced in the horizontal direction by the wind force. Depending on the size, there is a possibility that the structure or seismic isolation support will be shaken significantly beyond the design displacement (hereinafter referred to as “earthquake design displacement”) when an earthquake is assumed. Furthermore, when the seismic isolation support is a seismic isolation laminated rubber, due to the fluctuating axial force generated in the seismic isolation laminated rubber by wind force,
The seismically isolated laminated rubber, which is weak against tensile load, may also be subjected to tensile force.
【0005】以下、これらの問題点を具体的に説明する
ため、図12を参照して建築物aに作用する風力Pと地
震力Rとを比較し、併せて免震積層ゴムに作用する変動
軸力Xについて検討する。In order to explain these problems in detail, the wind force P acting on the building a and the seismic force R are compared with reference to FIG. The axial force X will be examined.
【0006】この建築物aは、総2階に建てられた高さ
h=6(m)、縦幅A=10(m)、横幅B=6
(m)、重量W=約20(ton)のもので、建築物a
の底面の四隅それぞれには免震積層ゴムが配置される。
この建築物aに作用する地震力Rは、ベースシェア係数
αを0.2とするとR=α×W=4(ton)となる。This building a has a height h = 6 (m), a height A = 10 (m), and a width B = 6, which are built on the second floor.
(M), weight W = about 20 (ton), building a
Seismic isolation laminated rubber is placed at each of the four corners of the bottom surface of the.
The seismic force R acting on the building a is R = α × W = 4 (ton) when the base share coefficient α is 0.2.
【0007】一方、風力Pは、縦幅A側に真横から風が
当たるとすると、風圧g=60×h1/2=60×61/2=
146.9(kg/m2)≒0.147(ton/
m2)、受風面積S=h×A=6×10=60(m2)よ
り、P=g×S≒8.8(ton)となり、前記地震力
Rの二倍以上の大きさとなる。なお、前記風圧gの算出
に際しては風力係数は1.0とした。On the other hand, if the wind force P strikes the vertical width A side from the side, the wind pressure g = 60 × h 1/2 = 60 × 6 1/2 =
146.9 (kg / m 2 ) ≈0.147 (ton /
m 2 ), the wind receiving area S = h × A = 6 × 10 = 60 (m 2 ), P = g × S≈8.8 (ton), which is more than twice the seismic force R. . The wind force coefficient was set to 1.0 when calculating the wind pressure g.
【0008】したがって、地震力Rに基づいて設定され
た免震積層ゴムの地震設計変位が例えば10cmである
場合に、風力Pが建築物aに作用すると、建築物aが1
0cm以上変位して大きく揺れる恐れがあることがわか
る。また、その場合には、免震積層ゴムがその許容範囲
を越えて変形し、転倒したり損傷したりする恐れもあ
る。Therefore, when the seismic design displacement of the base-isolated laminated rubber set on the basis of the seismic force R is, for example, 10 cm, when the wind force P acts on the building a, the building a becomes 1
It can be seen that there is a risk of displacement by 0 cm or more and significant shaking. Further, in that case, the seismic isolated laminated rubber may be deformed beyond its allowable range, and may fall or be damaged.

が作用しないことが必要である。Next, the fluctuating axial force X acting on the seismically isolated laminated rubber
think about. In order for the building a not to fall, the moment at a certain point due to the weight W of the building a is greater than the moment due to the wind force P at that point. That is, it is necessary that the variable axial force X generated in the seismic-isolated laminated rubber is sufficiently smaller than the long-term axial force W / 2 and no tensile force acts on the seismic-isolated laminated rubber.

止する手段が必要となる。Taking the building a shown in FIG. 12 as an example, consider the fluctuating axial force X acting on the base-isolated laminated rubber. The magnitude of the fluctuating axial force X at the points Q and Q ′ at both ends is X =
(H / 2) × P / B = 4.4 (ton), which is smaller than the long-term axial force W / 2 = 10 (ton). However, when the building a shown in FIG. 12 is, for example, a three-story building (height h = 9 m), the variable axial force X becomes 12.2 (ton), and the long-term axial force X = 1 at that time.
Since it approaches 5 (ton), it is necessary to fully consider the possibility that the point Q will rise and the building a will be inclined and a tensile force will be generated in the base-isolated laminated rubber. Of course, considering that the wind blows up to the eaves of the building a, 2
Even in the case of a story, it is necessary to have a means for preventing the building a from tipping over for safety.

生じ得る。As described above, since the seismic isolation function and the wind resistance function of the building a are contradictory to each other, it is very difficult to equip the building a with both of them at the same time. However, since the seismic isolation laminated rubber that is stronger than the cross-sectional area is used, the above-mentioned problem may occur remarkably.

When displaced, the inner surface of the vertical portion 8b1 of the locking plate 8b locks the outer end of the moving plate 8a. As a result, even when the building 4 is subjected to a wind force larger than the seismic force, the horizontal displacement of the building 4 causes the earthquake design as described in the section [Problems to be Solved by the Invention]. It is limited to the displacement or less, and the seismic isolated laminated rubber 6 will not be deformed beyond its allowable range. For example, when the earthquake design displacement is 10 cm, the predetermined amount D is 10 c
If it is set to m, the displacement of the building 4 and the seismic isolation laminated rubber 6 due to the wind force will not be larger than 10 cm. Therefore, even when a seismic isolation structure is applied to a lightweight building, it is possible to prevent excessive horizontal displacement of the building 4 due to wind force and damage to the seismic isolation laminated rubber 6.

As a result, no tensile force acts on the seismic isolated laminated rubber 6, and the building 4 can be reliably prevented from falling. Also, as described above, the horizontal portion 8b
If the predetermined dimension E of the portion where 2 and the moving plate 8a face each other is set to be larger than the earthquake design displacement, the moving plate 8a will become the locking plate 8
Even when it moves a predetermined amount D in the direction away from b, the horizontal portion 8b2 and the moving plate 8a always face each other, so that the building 4 can be surely prevented from falling. For example,
When the earthquake design displacement is 10 cm, the predetermined amount D is 1
By setting 0 cm and the predetermined size E to 15 cm,
The movable plate 8a and the horizontal portion 8b2 vertically face each other for at least 5 cm.
