GRG lower hanging aluminum grating combined type double-layer anti-sound suspended ceiling
The invention relates to a GRG lower hanging aluminum grating combined type double-layer sound reflecting suspended ceiling. The GRG lower hanging aluminum grating combined type double-layer sound reflecting suspended ceiling comprises a steel frame, a GRG sound reflecting plate arranged below the steel frame and a grating module arranged below the GRG sound reflecting plate. The GRG sound reflecting plates are fully distributed below the steel frame, the GRG sound reflecting plates obliquely extend from one side to the other side below the steel frame, and a sound source area is arranged below the lower position where the GRG sound reflecting plates obliquely extend correspondingly; the grating module is obliquely arranged along the obliquely extending GRG sound reflecting plate, the surface density of the GRG sound reflecting plate is 120 kg/m < 2 >, the thickness of the GRG sound reflecting plate is 7 cm, and the air permeability of the grating module is at least 50%. Through the arrangement of the GRG sound reflecting plate, a sound reflecting structure is formed above the sound source, the reverberation effect of sound in a space is improved after the sound source is subjected to sound reflecting through the sound reflecting plate, and the sound quality effect is improved; on one hand, the grating module provides a sound transmission purpose for GRG sound reflection, and can avoid sound defects caused by non-uniform sound reflection effect.
本发明涉及一种GRG下挂铝格栅组合式双层反声吊顶，包括钢架、设置在钢架下方的GRG反声板、设置在GRG反声板下方的格栅模块；GRG反声板沿钢架下方满布，GRG反声板沿钢架下方一侧向另外一侧倾斜延伸布置，对应GRG反声板倾斜延伸的低位下方为声源区域；格栅模块沿倾斜延伸的GRG反声板倾斜设置，GRG反声板的面密度为120kg/m2，厚度为7cm，格栅模块的透空率至少为50％。本发明通过GRG反声板的设置使得声源上方形成反声结构，声源经反声板反声后增加空间内声音的混响效果，提升音质效果；格栅模块一方面为GRG反声提供透声目的，还可以避免反声效果不均匀出现声音缺陷。
