ABSTRACT:
A support pillar system for a magnetically-shielded room including several support pillars, each support pillar including a nested structure formed by a first structure and a second structure surrounding the first structure. The upper end of the first structure has a threaded part and a member provided with a thread and disposed about the threaded part. The shielding structure of the magnetically-shielded room is attached to the second structure of the support pillar, whereby the floor of the room is supported on the upper end of the first structure. When the member provided with a thread is tightened in a locking position, it locks the first structure and the second structure together, whereby the vibration of the floor is transmitted to the shielding structure and the shield vibrates substantially in synchronization with the vibration of the floor of the room. When the member is threaded into an open, unlocked position, the locking of the second structure is released vis-a-vis the first structure, whereby the inner room is allowed to vibrate, irrespective of the vibration of the other shield structures, and hence, the potential vibration of the room is not transmitted to the shielding structures.
