Class Information
Number: 52/393
Name: Static structures (e.g., buildings) > Relatively yieldable preformed separator (i.e., expansion joint)
Description: Structure including fixedly related juxtaposed components with a substantial area of the opposed faces of the components being spaced from each other by a preformed, yieldable separator which is compressed between and acts to resiliently resist movement of the components towards each other.
