ABSTRACT:
A light weight locking structure for a suspended ceiling construction of T-shaped strip grid profile bars supportively engaged by nodal plates having radiating arms in which the arms terminate in upwardly bent locking projections, and the profile bars are provided with slots in the cross-bar of the T for cooperatively receiving the locking projections of the associated arm. After engagement of the locking projections in the slots of the respective profile bar, the projections are bent over to rigidly lock the profile bars to the nodal plate.
