ABSTRACT:
A contaminant shield is located above the finished ceiling in a building or office space and below potential sources of intrusive liquid contaminants to prevent such contaminants from leaking through the ceiling and intruding into the user space therebelow where sensitive electronic equipment may be located. The flat, imperforate expanse of the shield may be sloped to a slight degree such that liquids falling onto the shield are immediately drained therefrom. The shield is formed by a multitude of generally flat panels joined along their opposite sides to elongated, generally horizontally extending supports having provisions for clamp-like, watertight connections with the panels. Joints formed by abutting panels are sealed in a watertight manner through the use of gaskets sandwiched between downturned marginal edges of the panels. The entire shield may be suspended from overhead structure such as the roof of the building or floor slab of the next higher floor by cables and may, in turn, provide a means from which the finished ceiling may be suspended.
