摘要
为了避免房间之间的介质被声能激发时产生大气噪声及直接的机械激发的撞击噪声传播影响演播厅的声学效果,中央电视台新台址工程演播厅地面采用浮筑结构体系。以CCTV主楼2 000m2演播厅为例,介绍了演播厅浮筑地面的主要材料性能指标、施工工艺及施工要点。目前,该工程已施工完毕,各项技术参数控制到位,施工质量达到国家规范要求。
To avoid the effect of propagation of atmospheric noise, caused when the media in the room is excited by acoustic energy, and machine impact noise on the acoustic effect of large television studio, the ground of the television studio in CCTV Headquarter building used floating floor. Taking the 2 000m2 television studio for an example, the paper introduces the main material performance indexes, construction technique and key construction point of the floor. At present, the floor construction has been completed and each technique parameter is found to comply with the national code.
