Abstract
In a panel ceiling, a grid that supports panels has main beams and cross beams. In assembly, the main beams are directly attached to an overhead structure and the cross beams and panels are assembled onto the main beams. Stepped slots in the main beams enable the cross beams to be locked to the main beams to keep the cross beams and panels aligned.
