| 中文摘要: |
| 绿色建筑对建筑健康性、舒适性和环境性提出了更高要求，满足楼板隔声性能要求是其基本的功能要求，但现实设计中却往往不被重视。建筑楼板作为分隔空间的构件，工程中应重视去解决楼板撞击声的隔声问题。以钢筋混凝土住宅楼板为基准，考虑了弹性材料类型、厚度、质量密度、动态刚度以及浮板质量和厚度等因素，给出了不同系列浮筑楼板做法，通过理论分析和试验，研究了其隔声性能的变化。研究结果对于建筑楼板的隔声降噪设计提供了技术支撑和案例经验，对于优化改善建筑隔声性能有积极意义。 |
| 英文摘要: |
| The green building puts forward higher requirements for the health, comfort and environment of the building, and the sound insulation performance of floor is the basic functional requirement, but it is often ignored in the practical design. As a construction component of separating space, the building slabs must be seriously considered in order to solve the sound insulation problem caused by floor impact. Based on reinforced concrete residential floor, by taking into account the relevant factors such as resilient material type, thickness, mass density, dynamic stiffness and the quality and thickness of floating slab, different series of floating floor structure are developed. The theoretical analysis and experimental study on the sound insulation performance of different floating floor structures are carried out in this paper, and the results can provide technical support and case experience for the noise reduction design of building floor, and have positive significance for optimizing and improving the sound insulation performance of buildings. |
