Abstract:
A seismic expansion joint cover assembly that is adapted to span a motion-absorbing gap between a floor A on one side of the gap and a floor B on the other side of the gap and that permits relative movements of floors A and B substantially horizontally toward and away from each other along an x-axis perpendicular to the gap and relative movements of floors A and B substantially horizontally relative to each other along a y-axis parallel to the gap, comprisinga bridge panel, a retainer adapted to be affixed to floor A and supporting a first end of the bridge panel for movement along in the y-axis direction and against movement in the x-axis direction relative to floor A, a recess frame adapted to be affixed in a recess in floor B that receives portions of the bridge panel in all positions of the bridge panel relative to floor B, a recess cover plate adapted to cover the recess, having a first end supported in sliding relation on the bridge panel in all positions of the bridge panel relative to floor B, and a second end joined to an end member of the recess frame remote from the motion-absorbing gap, and a collapsible/extensible honeycomb panel adapted to be received in the recess in floor B and supporting the portion of the recess cover plate that spans the recess between the second end of the bridge panel and the end member of the recess frame.
