According to the above content, the utility model discloses a sound absorption luminous integrated furred ceiling of A level fire prevention has following effect:

on the premise of considering fire control specifications and spray arrangement, the perforated plate and the cavity air layer of the ceiling unit are utilized, sound absorption and noise reduction and uniform floodlight illumination of a large underground space are realized, and an indoor light environment and an indoor sound environment are improved.

2. The sound absorption coefficient can reach 0.6, and the noise reduction effect on low-frequency noise is particularly obvious. The method can effectively absorb background noise generated by equipment, reduce the low-frequency reverberation time, reduce the masking effect of low-frequency sound on human voice and improve the speech definition. Effectively relieve vicious circle caused by speaking loudly due to insufficient speech definition.

3. The floodlighting provides high and uniform plane illumination, and effectively avoids the problems of glare and uneven illumination.

4. The integrated ceiling is simple in structure and convenient to construct, assemble, daily check, maintain and replace. The fireproof material is suitable for buildings with quality requirements on space light environment and sound environment, such as transportation hubs and large public buildings, and is particularly suitable for large underground public spaces which must use A-level fireproof materials.

The details of the present invention can be obtained from the following description and the attached drawings.
