TECHNICAL FIELD The present invention relates to a structure in which a column and a wall are joined in a seismic isolation system on an intermediate floor. Background art

The vibration transmitted from the ground to the lower structure due to the seismic motion is transmitted to the upper structure above the seismic isolation device by interposing the seismic isolation device on the column part of the intermediate floor of the structure. An intermediate floor seismic isolation structure that reduces vibration propagation is known.

Therefore, if there is a wall on the floor where the seismic isolation device is installed, a horizontal slit is provided to absorb this deformation, and the wall is connected to the lower structure and the upper structure. Need to be separated between In addition, it is necessary to provide a notched space on the wall adjacent to the seismic isolation device to prevent deformation of the seismic isolation device. Japanese Patent Application Laid-Open No. 2000-120297 discloses a proposal for improving the design by closing the cut-out space.

However, this prior art is based on a notch in the wall adjacent to the seismic isolation device. The opened space is rotatably connected to the connecting member via a hinge. For this reason, the connecting member is required to have sufficient expansion and contraction performance to follow the deformation and rotation performance of the hinge part.
