対策が必要とされる。2. Description of the Related Art Conventionally, various types of seismic isolation devices for seismic isolation of a building against seismic motion are known, but most of them have a seismic isolation effect against horizontal vibration caused by an earthquake. However, the anti-vibration effect against vertical environmental vibration generated by transportation or the like is usually hardly obtained.
In recent years, due to the advanced use of land, especially in urban areas, there has been an increasing demand for constructing buildings in places with extremely poor location conditions, such as on railway tracks or on the subway line. Buildings constructed in various places need seismic isolation and vibration isolation measures that are particularly effective against horizontal and vertical three-dimensional vibrations.

れる。According to the present invention, the vertical vibration absorber at the upper part of the seismic isolation device is made up of the tapered part of the steel rod and the upper flange of the horizontal vibration absorber at the lower part by the vertical and horizontal deformation restraining members. Horizontal deformation exceeding this clearance is restrained by the minute clearance interposed between the tapered hole that penetrates the lower flange of the part and horizontal vibration of the earthquake is mostly absorbed only by the lower horizontal vibration absorption part Is done. In addition, vertical vibration of the ground that is normally generated by transportation means is effectively absorbed by the vertical vibration absorbing portion within a small clearance between the tapered portion of the steel bar and the tapered hole, and therefore, the horizontal vibration at the time of the earthquake Vertical vibrations caused by vibrations and transportation are absorbed by the three-dimensional seismic isolation device integrated with the horizontal vibration absorption unit and the vertical vibration absorption unit. The resonance of the vibration absorber is attenuated by the vertical vibration damping member, and the horizontal and vertical seismic isolation and vibration isolation of the building are effectively performed. When the vertical vibration of the ground is large and exceeds the range of the minute clearance between the tapered portion of the steel rod and the tapered hole, the tapered portion of the steel rod is constrained by the tapered hole and the vertical vibration of the vertical vibration absorbing portion is reduced. Excessive deformation is restrained, and tensile breaking of the vertical vibration absorbing portion is prevented.
