隔声减振聚合物砂浆在楼面施工中的应用

Application of Sound Insulation and Vibration Reduction Polymer Mortar in Floor Construction

北京新机场安置房项目(榆垡组团)9标段(6片区)工程楼地面采用隔声减振聚合物砂浆作为楼地面中的浮筑层,断绝了固体传声效应,增强声阻抗力。介绍了该技术的工艺流程和质量控制要点。实践表明,隔声减振聚合物砂浆对撞击声在整个频率范围内具有很好的声音阻断效果,能有效隔绝撞击噪声和空气传播噪声,具有良好的社会效益和经济效益。

The floor of Section 9(Piece Area 6)of the Beijing New Airport Resettlement Housing Project(Yufa Group)adopts sound-insulation and vibration-reduction polymer mortar as the floating floor,which cuts off the solid-borne sound transmission effect and enhances the acoustic impedance.The process flow and quality control points of this technology are introduced.The practice shows that this sound-insulation and vibration-reduction polymer mortar has a good sound-blocking effect on impact sounds in the whole frequency range,and can effectively isolate impact noise and airborne noise,which obtains good social and economic benefits.
