Expansion Joint System For Open Air Structures |
摘要 |
An expansion joint system for bridging an expansion joint gap between two spaced-apart underlying stair structures. The expansion joint system includes a movable plate that is connected to a fixed plate through a hinge. The hinge connection permits the movable plate to move in response to thermal movements and seismic events that causes the width of the expansion joint to open to a greater width or close to a smaller width. Following the seismic or thermal event, the hinge connection automatically returns the movable plate to its original position.
