Abstract: A suspended ceiling assembly and method for mounting such an assembly to provide an inner ceiling suspended under the framework of a roof. The assembly includes a plurality of suspension beams suspended in parallel to each other under the framework by cables. A plurality of mounting rails are mounted transversally underneath the suspension beams with the help of connecting members. The connecting members each have a sleeve-shaped body for enclosing a cross-section of a corresponding suspension beam therein, fasteners for fastening the sleeve-shaped body to this corresponding suspension beam, and a hook-shaped bottom portion engageable with the top flange of a corresponding mounting rail for supporting this mounting rail. The ceiling tiles are mounted between the bottom mounting portions of adjacent mounting rails. Advantageously, the assembly according to this invention is versatile and allows to easily mount an inner ceiling of a desired shape to any framework.
