Description of the Related Art In recent years, demand for seismically isolated buildings that employ seismic isolation devices to prevent seismic energy from being directly transmitted to buildings has increased, and construction has been promoted. By the way, as for the connection of the bridge between the base-isolated structure building and the outer ground (dry area), since the vibration periods of both are different, use an expansion joint so that they do not adversely affect each other mechanically. Is of course necessary. However, at present, it is general that a building b is protruded from the building a side to the outer peripheral ground c as shown in FIG. Symbol d is a seismic isolation device. However, in the case of the bouncing frame b as described above, a step occurs at the crossing portion, so that the road surface (frame upper surface) becomes an inclined surface (slope), and when the base-isolated building a vibrates, the bouncing frame b Since b also vibrates in the same manner, there is a risk that the person riding on it may be stepped off.
