ABSTRACT:
A method and apparatus for producing a honeycomb pattern of projecting frameworks from a drop ceiling utilizes cardboard rectangular frameworks having four side walls with respective hinged locking flaps along a top edge of the side walls. As the cardboard frameworks are inserted from below into rectangular support frames of the drop ceiling, the hinged locking flaps are pushed flush against outside surfaces of the framework side walls until they clear the support frames. After clearance is achieved, the locking flaps assume a locking position wherein they abut against a corner formed by T-section channels of the drop ceiling defining the support frames.
