ROOF SEISMIC MOTION-ABSORBING GAP COVER

摘要

A seismic roof motion-absorbing gap cover assembly includes an elongated y-axis slideway affixed to a building unit B on one side of the gap and extending parallel to the gap and a y-axis slider slidably received on the y-axis slideway. Roof support members are secured to the y-axis slider in spaced apart relation against horizontal movements. A roof having one end affixed to a building unit A on the other side of the gap spans the gap and is supported on the roof support members by elongated spaced-apart x-axis slide members for movement along an x-axis perpendicular to the gap. Each x-axis slide member has a length such that it is supported by the roof support member throughout a range of displacements in the x-axis direction of the building units between maximum and minimum design displacements in an earthquake from a neutral position.
