Abstract
Description
Technical Field
[0001] This invention relates to the field of ceiling technology, specifically to a prefabricated ceiling system and its assembly method. Background Technology
[0002] A suspended ceiling refers to a type of decoration applied to the top of a room. It is an important part of interior decoration.
[0003] The suspended ceiling includes a floor slab, a suspension rod inserted and fixed to the floor slab, a keel frame connected to the suspension rod, and decorative panels fixed to the keel frame.
[0004] During ceiling construction, due to the height of the floor slab, long hangers are required for installation. The hangers are fastened to the keel frame with two nuts. While these nuts serve to fix the keel frame, they also need to be adjusted to ensure the keel frame is level. Because the lower nut is supported by the weight of the keel frame, turning it requires considerable force. Given the height of the ceiling, this is difficult and time-consuming for workers, increasing the efficiency of the ceiling construction. Furthermore, the horizontal and vertical keels are directly fixed together with screws. Due to gravity, these screws are prone to slippage, posing a safety hazard during ceiling use.
