Abstract
In a ceiling structure, wood structural components, such as wood joists or trusses, have wood shield pieces interposed between them and a sheet-like ceiling which is carried by the structural components. The shield pieces protect the structural components in the event of a fire below, in that they must be consumed by the fire before the structural components are jeopardized, and this requires additional time which extends the fire rating of the ceiling.
