房中房隔声减震系统施工技术

Construction Technique of Box-in-Box Soundproof and Shock Absorbing System

数字广播大厦项目中的功能性房间设计标准非常严格,工程对房中房隔声构造及门窗隔声要求高,噪声控制难度较大。房中房隔声减震系统主要由浮筑地面、隔声墙体、隔声吊顶、隔声门和隔声观察窗五部分构成。通过严控工艺流程及施工要点,确保隔声降噪效果满足要求。

The functional rooms of Digital Broadcasting Building project adopted very strict design standard and had high requirements for soundproof structure,doors and windows of subdivided units,where there were great difficulties in noise control.Boxin-box soundproof and shock absorbing system is mainly composed of five parts,including floating floor,soundproof wall,soundproof suspended ceiling,soundproof doors and soundproof viewing window,etc.Process flow and key construction points were strictly controlled to realize satisfied soundproof and shock absorbing effects.
