Description

Technical Field

[0001] The utility model relates to a double-layer gypsum board ceiling structure, specifically a double-layer gypsum board ceiling structure, belonging to the technical field of ceilings. Background Technique

[0002] Gypsum board is a material mainly made of building gypsum. It is a building material with the advantages of light weight, relatively high strength, thin thickness, convenient processing, good sound insulation, heat insulation and fire prevention properties, etc. It is one of the new lightweight boards that are currently being focused on developing; gypsum board is generally widely used in various buildings such as residences, office buildings, stores, hotels and industrial factories for interior partition walls, wall cladding panels (replacing wall plastering layers), ceilings, sound-absorbing boards, floor baseboards and various decorative boards, etc., and is not suitable for installation in bathrooms or kitchens indoors.

[0003] Currently, due to the easy cracking of gypsum board, cracking may also occur accidentally during installation, which greatly reduces work efficiency. And after the gypsum board cracks, a new one needs to be replaced. The existing gypsum board is relatively heavy itself and the installation height is relatively high, so the installation of the gypsum board ceiling is very troublesome. And after the installation is completed, if problems such as installation misalignment occur, it is also very troublesome to disassemble the gypsum board. Content of the Utility Model
