Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an isolation unit,

The present invention relates to an isolation unit and an isolation device including the same. More particularly, the present invention relates to an isolation unit and an isolation device including the same.

Currently, many companies and research institutes store and archive important documents and data, etc., and the laboratory is equipped with expensive experimental equipments.

Since the computer or the expensive experimental equipment which preserves such important data is damaged, the damage to the enterprise or the research institute can cause enormous damage. Therefore, there is a need for a protection device capable of protecting them from external impacts

Seismic excursion is one of the factors of external impact. Seismic forces are largely seismic, seismic, and earthquake resistant.

Seismic protection is a broad concept that protects structures from earthquakes. It is a measure to make structures strong enough against seismic forces. Seismic isolation is a method of reducing damage to seismic structures And the vibration is a proactive means of sensing and controlling vibrations caused by earthquakes and winds.

Therefore, the technology to protect the expensive equipment in the building comes from the seismic design technique. It is important that seismic isolation devices for this purpose move naturally according to the seismic force so that the impact of the seismic force is minimized or transmitted to the equipment to be protected or, if possible, not transmitted. Therefore, there is a demand for a seismic isolation device that can move more smoothly according to the seismic force, increase the seismic effect through the seismic force, and improve the stability to the initial state when the seismic force disappears.
