Abstract
An expansion joint having a weather resistant cover and a fire barrier. The cover is a bellows attached to the upper surface of the adjacent joint structure by mounting flanges, and the barrier is a fire resistant inorganic fabric sheet mounted in the joint. The fabric supports resilient fire resistant inorganic fibrous insulation and is connected to the adjacent joint structure by mounting flanges. The flanges may be 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.
