り、費用の高騰を招く、等の不具合がある。By the way, when the upper structure is a medium-to-low-rise building and is relatively lightweight, the seismic isolation support device is structurally free to move, and the lateral rigidity is further greater than that for a large structure. When the building is taken small and a strong wind such as a typhoon acts, or the ascending force is generated due to the earthquake motion, the building receives the falling force, and the building falls. For this reason, various measures have been proposed as measures for preventing the floating, and there are a device attached to the seismic isolation support device itself and a device installed separately (see Japanese Patent Laid-Open No. 60-261870). However, in the former, the direction is specified,
The latter has a problem that the size of the device becomes large, the installation work becomes troublesome, and the cost rises.

付け態様を採りうる。The present invention specifically adopts the following constitutions. The first invention relates to a seismic isolation system, which has a vertical support function between the upper structure and the lower structure, reduces vibration transmission from the lower structure in the horizontal direction, and moves the upper structure with horizontal displacement. In a structural system in which a seismic isolation support device having energy absorbing ability is interposed, a vertical rigid horizontal flexible member having a large vertical rigidity and freely displaceable in the horizontal direction is used, and the vertical rigid horizontal flexible member is used. It is characterized by restraining the upward displacement of the superstructure with the rigidity in the vertical direction. In the above-mentioned configuration, the vertical rigid horizontal flexible member is a bent leaf spring formed by bending in the vertical direction, or two
The sheet steel is formed in a V shape, and each end portion is bendable via a hinge. The second invention relates to a lift preventing device in a base-isolated structure system, which has a vertical support function between an upper structure and a lower structure, reduces vibration transmission from the lower structure in the horizontal direction, and prevents horizontal displacement. A device used in a structural system in which a seismic isolation support device having a kinetic energy absorption capability of an accompanying superstructure is interposed, the casing being mainly installed in the lower structure side and having a box body that opens upward. A columnar member that is installed on the upper structure side and has a columnar body as a main body that is inserted into the casing; and a vertical rigidity that is disposed in the casing and is interposed between the casing and the columnar member. Is a vertical rigid horizontal flexible member that is largely displaceable in the horizontal direction. This floating prevention device can be installed in the opposite manner to the upper structure and the lower structure.

上述の免震支持装置の機能を何ら阻害することはない。(Operation) In a normal state, that is, in a normal state, the load of the upper structure is transmitted to the lower structure through the seismic isolation support device, and the predetermined lateral rigidity of the seismic isolation support device causes the upper structure to roll. Does not occur. At this time, the anti-floating device does not exert a special action, in other words,
It does not hinder the function of the seismic isolation support device described above.

により直ちに吸収される。When a strong wind acts on the upper structure as a lateral wind during a typhoon or the like, the upper structure is lightweight, and the lateral rigidity of the seismic isolation support device is small, so that the seismic support device causes a sway and an uplift. In this floating prevention device,
Vertical rigidity The horizontal flexible member follows this lateral displacement without restraining it at all, but resists the rise with its vertical rigidity. Then, the lateral vibration is immediately absorbed by the vibration absorbing action of the seismic isolation support device.

拘束されることは勿論である。When an earthquake motion occurs, the vibration of the lower structure is transmitted to the upper structure through the seismic isolation support device. The seismic isolation support device lengthens the vibration of the upper structure to resonate with the natural period of the upper structure. Never. Thus, the vibration absorption of the seismic isolation support device damps the vibration of the superstructure. When the roll becomes large, the superstructure will cause a harmful locking phenomenon, but the present anti-lifting device resists this with its longitudinal rigidity and prevents the lifting. Further, it goes without saying that the vertical vibration included in the seismic wave is also restrained by the lifting prevention device.

ちに吸収される。When a strong wind such as a typhoon acts as a cross wind on the superstructure G on which the lifting prevention device S is installed, the superstructure G is lightweight and the seismic isolation support device D has small lateral rigidity. As a result, the swaying and uplifting occur. In the uplift prevention device S, the vertical rigidity horizontal flexible member 3 follows this lateral displacement without restraining it, but resists the uplift with its vertical rigidity.
Rolling is immediately absorbed by the energy absorbing action of the seismic isolation support device D.

されることは勿論である。When an earthquake motion occurs, the vibration of the foundation B is transmitted to the superstructure G through the seismic isolation support device D, but the seismic isolation support device D causes the sway of the superstructure G to have a longer period, and It does not resonate with the natural period. Thus, the vibration is reduced by the energy absorbing action associated with the plastic deformation of the lead plug of the seismic isolation support device D. When the rolling of the superstructure G becomes large, a harmful rocking phenomenon occurs in the superstructure G, but the present anti-lifting device S resists this due to its vertical rigidity and prevents the lift. In addition, it goes without saying that the vertical vibration included in the seismic wave is also restrained by the lifting prevention device S.

To do. In addition, the present floating prevention device S has a simple structure, and the installation work of interposing it between the upper structure G and the lower structure B is also facilitated, and an economical floating prevention measure can be realized.
