Performance evaluation test

Design and verification of seismic isolation ducts

・In order to accommodate large relative displacements of the seismic isolation layer, it is necessary to ensure that the canvas of the duct is long and that it has sufficient flexibility.
However, if left as it is, the canvas part will hang down and block the internal airflow.
Therefore, by installing a hanging part in the middle part of the canvas, we solved the above problem and realized smooth operation against displacement.

・Regarding length dimensions and various structures, we use our know-how and experience cultivated as a manufacturer of seismic isolation joints to perform theoretical design and structural analysis to achieve optimal designs.
