Clearance gap providing for great movement of seismic isolation buildings in case of earthquakes is arranged for the joint part connecting the bedding and those buildings or conventional non-seismic isolation buildings. Quake-absorbing Expansion Joint Cover refers to the covering material used for this clearance gap. This covering material must have the function to prevent it from being destroyed or dropping out in case of earthquakes. Therefore, the safety of our covering material has been confirmed by using our self-developed vibration table.

免震建物と非免震建物や基礎との取合い部には、免震建物の地震時の大きな動きに見合った隙間が設けられます。免震エキスパンションジョイントカバーは、この隙間のカバー材のことで、地震時に破壊や脱落したりしない機能を求められています。当社のカバーは、自社開発した振動台を用いて安全性を確認しています。
