Abstract
A ceiling structure, particularly for 'dry-wall' type panels, employing a suspended ceiling grid structure having a plurality of parallel main runners and a plurality of parallel cross runners extending transversely to, and having their ends engaged with the main runners to form a rectangular grid structure, with each of the runners having flange means adapted to support a ceiling panel around the periphery thereof, the ceiling panel being reinforced by at least one cross member extending along the upper face of such ceiling panel and is secured thereto. In a preferred form of the invention, the ceiling panels are adapted to be successively installed in the grid structure with the associated reinforcing members being installed in operative position and secured to the associated panel following installation of the latter by means of screws or a suitable adhesive. Preferably, the reinforcing members are interlocked at least at one end with an adjacent runner to restrict upward movement of the reinforcing member with respect to such runner. The reinforcing member may be so designed that it is snapped into operative engagement, at each end thereof, with an adjacent runner, or provided with means extending through an opening in the adjacent runner and forming stop means for determining the lateral positioning of a corresponding reinforcing member cooperable with the following adjacent ceiling panel.
