DEFINITION

Classification: 52/408

(under the class definition) Structure in which a

construction assembled at the job site includes a sheet form member which is imperforate except for openings accommodating preformed means, e.g., ties, the member being held between opposed surfaces of components or layers which are made of a material which differs in kind from that of the member, with the major faces of the member being in contact and substantially coextensive with the opposed surfaces of the components or layers or are embedded in a bonding material between such surfaces.

(1) Note. Dividing laminae, per se, having features on opposed surfaces for retaining opposed layers are in this or the indented subclasses.

(2) Note. Search appropriate subclasses, below, for other layered constructions.
