IMPACT ABSORBING INSERT FOR CEDM SEISMIC PLATES

摘要

An impact absorbing device for CEDM(Control Element Drive Mechanism) seismic plates is provided to prevent a direct collision between the seismic plates and to reduce vibration of the seismic plates through a main body unit. An impact absorbing device for CEDM seismic plates absorbs impact of the seismic plates which are installed on an upper part of a CEDM to be separated from each other at predetermined intervals. The impact absorbing device for the CEDM seismic plates includes a main body unit(21) and a cover unit(22). The main body unit is made of elastically deformable material and inserted into a gap between the seismic plates. The cover unit is extended from an upper part of the main body unit in a horizontal direction and limits downward motion of the main body unit.
