Vibration isolation supporting structure and vibration isolation system
A vibration isolation supporting structure and a vibration isolation system that can prevent a high-frequency vibration and a low-frequency vibration generated on a floor of a building. The vibration isolation supporting structure includes a plurality of supporting portions erected facing each other in a predetermined area near a wall of a floor of a building, a supporting structure supported on the floor by the supporting portions, and a fixing device configured to fix the supporting structure to the floor, and when receiving a release command, the fixing device releases fixing of the supporting structure to the floor.
1. A vibration isolation supporting structure that prevents a vibration, comprising:
a plurality of supporting portions erected facing each other near a wall of a floor of a building;
a supporting structure supported above the floor by the supporting portions;
a leg extending toward the floor from the supporting structure;
a fixing device partially embedded in the floor and including two pistons sandwiching the leg of the supporting structure thereby fixing the supporting structure to the floor; and
an actuator connected to the two pistons that, upon receiving a release command, retracts the two pistons.
2. The vibration isolation supporting structure according to claim 1 , wherein
a plurality of the fixing devices are disposed to be spaced apart from each other in a longitudinal direction of the supporting structure.
3. The vibration isolation supporting structure according to claim 1 , wherein
the supporting portions support the supporting structure to be relatively rotatable.
4. The vibration isolation supporting structure according to claim 1 , wherein
the supporting structure includes at least one beam member.
5. The vibration isolation supporting structure according to claim 1 , wherein
the supporting structure includes a flat plate member.
6. A vibration isolation system that prevents a vibration using an vibration isolation supporting structure,
the vibration isolation supporting structure including:
a plurality of supporting portions erected facing each other near a wall of a floor of a building;
a supporting structure supported by the supporting portions;
a leg extending toward the floor from the supporting structure; and
a fixing device partially embedded in the floor and including two pistons sandwiching the leg of the supporting structure thereby fixing the supporting structure to the floor;
an actuator connected to the two pistons; and
a controller connected to the actuator;
wherein the controller is configured to, upon receiving a predetermined input, output a release command to the actuator, and
wherein the actuator, upon receiving the release command, retracts the pistons.
