Abstract
An expansion joint for interior or exterior use including a fire barrier comprised of a fire resistant inorganic refractory fiber fabric sheet which supports resilient fire resistant inorganic refractory fibers. The support sheet may be closed to form a sleeve. When used as an exterior expansion joint a weather resistant cover comprising a bellows or a cover plate is employed. When used in an interior application a cover plate may be employed to form a bridge over the expansion joint to provide a continuous flooring or to provide additional fire resistance. The fabric is attached to adjacent structure by mounting flanges in the form of a bifurcated clamp, and one of the fabric-engaging clamp faces may be crimped and pierced to better grip the fabric.
