Multi-family residential space, floor noise blocking sound absorption material and construction method

摘要

Lightweight and heavy impact sound generated in the upper and lower floors of multi-family living spaces is cut and absorbed to reduce the floor impact sound transmitted to the upper and lower floors. It is composed of a synthetic resin having a predetermined flexibility to sufficiently exhibit light weight and heavy impact sound relaxation performance even at low slab thickness. Air layer is formed on the inner layer in the middle part of the middle part between the floor floor noise material and the wall noise material, and the air layer is connected to the wall finishing mortar finish part to block and absorb the noise between the floor and the wall. And a construction method. To this end, the interlayer noise absorbing material is laminated on the upper part of the concrete slab. This can reduce excessive cost and noise environment problem by reducing construction cost by reducing interlayer concrete slab thickness that does not affect interlayer structure stability except lightweight foam concrete. By providing a structure that cuts out and absorbs the floor impact noise, the performance of light weight and heavy impact sound of 40db or less is achieved even at low thickness.
