THE PROTECTIVE SYSTEM OF ISOLATING DEVICE

摘要

The present invention relates to a protective system (100) for protecting a seismic isolation device (3) installed between an upper structure (1) and a lower column (2). The protective system comprises: a mounting member (110) installed to mount the protective system on a lower column (2); a wall (120) which is installed on the outside of the seismic isolation device (3) to protect the seismic isolation device (3) when the lower end part is coupled to the mounting member (110); and a fixing member (130) which fixes the upper end part of the wall (120) to the upper structure (1) and is installed on the upper structure (1) to allow the horizontal displacement of the wall (120) so that the function of the seismic isolation device (3) is ensured when the seismic isolation device (3) is deformed in a horizontal direction. According to the present invention, the protective system (100) can efficiently protect the seismic isolation device from fire, perched water, radiation, external impact, wind load, etc. by surrounding the seismic isolation device from the outside. Therefore, the protective system (100) can ensure the safety of a nuclear power generation seismic isolation device for the seismic isolation device remaining period of 100 years and can improve reliability of quality.
