隔声垫浮筑楼板的撞击声隔声性能研究

通过对钢筋混凝土楼板和隔声垫浮筑楼板的撞击声隔声性能测试,分析隔声垫的铺装方法和隔声垫厚度等对隔声垫浮筑楼板撞击声的隔绝作用。结果表明,隔声垫能有效降钢筋混凝土楼板撞击声的透射,铺装方法和隔声垫厚度对撞击声隔声性能均具有明显的影响。提出了隔声垫浮筑楼板的施工技术,可为钢筋混凝土楼板铺设隔声垫的施工提供参考。

Study on the sound insulation performance of floating floor with sound absorbent pad

Through the impact sound insulation performance test of the reinforced concrete floor and floating floor with sound absorbent pad,the effect of the shop installs method and the thickness of the sound absorbent pad on the sound insulation performance of floating floor with sound absorbent pad were analyzed. The results show that sound absorbent pad were effective for reducing the impact noise of the reinforced concrete floor,and the shop installs method and the thickness of the sound absorbent pad had obvious influence on the sound insulation performance of the floating floor. The construction technology of floating floor with sound absorbent pad was put forward,which provides reference for the construction of sound absorbent pad on reinforced concrete floor.
