减震隔声降噪地垫的研发

The Research of Vibration and Noise Reduction Mats

介绍我国分户楼板隔声及其隔声研究现状,详细阐述多层复合结构的减震隔声降噪地垫的结构、性能和安装,减震隔声降噪地垫与木地板配合使用,将其铺装于扫平层的140 mm厚现浇钢筋混凝土楼板之上,经江苏省建工建材检测中心检测,撞击声隔声为61 dB,能很好地满足住宅分户楼板撞击声隔声L'nT,W≤65 dB的要求。

This paper introduced and analyzed the current situation of sound insulation of household floor slabs in China and the current research situation of sound insulation.The current method of floating floor slabs for sound insulation and heat preservation had some drawbacks.Power Dekor had developed a detailed description of the structure,performance and installation of a multi-layer composite structure of shock and sound insulation and noise reduction floor mats.The floor mats were respectively PE dense layer,PE bubble layer and PE foam layer from top to bottom.The shock-absorbing,sound-proofing and noise-reducing floor mat was used in conjunction with the wooden floor,and it was laid on the 140 mm thick cast-in-situ reinforced concrete floor slab of the sweeper layer.The impact sound insulation is 61 dB,which can well meet the requirements of L'nT,w≤65 dB for impact sound insulation of residential floor slabs..
