This is an OA floor with seismic isolation function that is designed to protect important equipment from shaking during earthquakes. It is used in server rooms, command centers, and other rooms that must maintain their functions even in an emergency. Floor Utena" is incorporated into an OA floor, making it easier to install than conventional seismic isolation floors and allowing for a lower floor height. In addition, the seismic isolation area can be made larger by eliminating the need for an expansion (buffer plate).

Floor Utena
model number
FU
forte
It is maintenance-free, so there are no running costs after installation.
The integration of seismic isolation bearings and OA floors has made it possible to reduce the floor height.
The expansion (buffer plate) is no longer needed, allowing for a wider seismic isolation area.
No level mortar or anchors are required.
Suitable for small rooms, low height to ceiling, and renewals.
The damping mechanism and automatic homing mechanism are used to return to the origin after an earthquake.

This is a view of the seismic isolation of the floor utensils. The input seismic wave is from the southern Hyogo Prefecture earthquake that occurred on Tuesday, January 17, 1995.
structure
The structure has no inherent vibration period and is not affected by mounted load.
It has a low floor height and a large seismic isolation area (about 60% of room floor area).
The bearings are assembled at the factory, so there is no need for on-site adjustments.
Only one leveling operation is required.
Load capacity of seismic isolation floor is 5,000 N/m2.
