一、耐火与隔声的标准结构 1.声学特性根据传声等级标准(STC)和实验室测定,确定清水墙壁结构体系的隔声性能及楼板与顶棚的冲击噪声性能由冲击隔声等级确定。由于设计或工艺上的某些原因,清水墙壁结构体系在现场与实验室中的各种性能之间会出现一定的偏差。例如,由于侧向管道和空气渗漏等原因,将会引起隔声性能的降低。一般来说采用抗老化的、耐久的、有弹性
First, the standard structure of fire resistance and sound insulation 1.Acoustic characteristics According to the sound level standard (STC) and laboratory measurements, determine the sound insulation performance of the clean water wall structure system and the impact noise performance of the floor and the ceiling is determined by the impact sound insulation level. Due to certain design or process reasons, there will be some deviations between the various characteristics of the clear water wall structure system in the field and the laboratory. For example, due to lateral piping and air leakage, etc., acoustic insulation performance will be reduced. Generally speaking, anti-aging, durable and elastic
