下置式楼板隔声系统探究

The study on the sound insulation system of the lower floor slab

建筑声环境是建筑空间环境的重要组成部分,而建筑楼板隔声性能又是建筑声环境的重要指标。随着经济的快速发展、建筑法规的逐步完善和人们对建筑声环境要求的不断提高,良好的楼板隔声性能已经成为现代化优质宜居建筑的重要特征之一。通过设想一种下置式楼板隔声系统,将隔声、吸声材料铺设到楼板下方,设计2种下置式楼板构造方案,对每个方案的楼板进行声学测试,并结合工程实例,得出下置式楼板隔声系统的探究结论,为下置式楼板隔声系统在未来绿色建筑中的发展提供借鉴。

Building sound environment is an important part of building space environment,and the sound insulation performance of building floors is an important index of building sound environment.With the rapid development of economy,the gradual perfection of building regulations and the continuous improvement of people’s requirements on building sound environment,good sound insulation performance of floor slab has become one of the important features of modern high-quality livable buildings.In this paper,the author envisages a sound insulation system for floor slabs.It lays sound insulation and sound absorbing materials under the floor slab,designs two structural schemes of the floor slab with the acoustic test of each scheme,and finally obtains the exploration conclusion of the sound insulation system of the floor slab with the combination of the application of engineering examples.Through this study,it provides references for the development of the sound insulation system of the floor slab in the future green building.
