Description

Technical Field

[0001] The utility model relates to the technical field of ceiling boards, and specifically relates to a thin-type soundproof ceiling board. Background Art

[0002] Ceiling is a decorative and practical design for indoor ceilings, with multiple functions such as heat preservation, heat insulation, sound insulation, and sound absorption. At the same time, it is also a concealed layer for projects such as electrical, ventilation and air conditioning, communication, and fire prevention and alarm pipeline equipment. Ceiling plays an important role in modern interior decoration, and is not only used in home environments such as living rooms, kitchens, and bathrooms, but also widely used in public places such as offices and shopping malls.

[0003] In the traditional keel ceiling structure, the keel is usually built on the building top surface, and then the ceiling board is installed on the keel. However, the sound insulation effect of this traditional ceiling is limited, and it occupies a relatively large indoor floor-to-ceiling space. Therefore, we provide a thin-type soundproof ceiling board to solve the above problems. Content of the Utility Model
