3D SEISMIC ISOLATION FLOOR SYSTEM 3D seismic isolation floor

This is a 3-dimensional seismic isolation floor in vertical and horizontal directions that aims to protect critical equipment from shaking during earthquakes. It reduces the vertical and horizontal vibration acceleration on the floor during an earthquake.

Product Overview

Product name

3D seismic isolation floor system

model number

None for completely made-to-order items

feature

The seismic isolation effect does not change even if the size or position of the load on the seismically isolated floor changes.
Even if the size or position of the load on the seismic isolation floor changes, the floor does not sink as seen with coil spring seismic isolation floors, and the floor height is maintained at a constant level.
Friction dampers have reduced the discomfort associated with walking on the upper and lower seismic isolation floors.
We handle everything from vibration analysis to design construction and performance verification.

structure

System Floor Conceptual Diagram

Horizontal seismic isolation

Bearing bearings are placed under the air springs to support the seismically isolated floor and at the same time reduce horizontal forces transmitted to the floor during earthquakes.

Vertical seismic isolation

Air springs softly support the floor and reduce earthquake forces.
Compressed air generated from the compressor is supplied to the air spring while adjusting the air volume through the leveling valve to maintain the height of the seismic isolation floor at a constant level.
