Description

Technical Field

[0001] This utility model relates to the field of building decoration, specifically to a prefabricated curved sound-absorbing ceiling structure. Background Technology

[0002] With the rapid development of the building decoration market, curved, ultra-large space designs are increasingly being used in interior decoration schemes. Traditional GRG decorative layers have poor sound absorption capabilities, and for spaces with ultra-high ceilings and high noise requirements, the sound absorption of GRG decorative layers fails to meet the standards. For example, in an existing patent, authorized publication number CN209494108U, the patent title is: "A GRG Ceiling," which includes several GRG panels assembled on a steel keel and a first sealant, a mesh tape, and a second sealant sequentially arranged between the seams of adjacent GRG panels from the inside out. The back of the GRG panels has protruding edges, and limiting blocks are fixed between the two protruding edges of adjacent GRG panels by fasteners. The first sealant is caulking plaster. The GRG decorative structure in this scheme has a relatively high density and good sound wave reflection, and the scheme lacks corresponding sound-absorbing structures, resulting in poor noise reduction capabilities and consequently, indoor noise.

[0003] Therefore, the technical problem that this application needs to solve is: how to reduce noise in the indoor environment. Utility Model Content
