■ 预制外墙外保温构造 小型轻质预制混凝土装饰挂板可以像石材一样，采用连接件安装固定在龙 骨或主体结构

上，墙身的保温做法类似于石材幕墙的外保温做法。

PC external wall outside-thermal-insulation structure

Small-sized or light-weighted PC panels could be fixed on steel skeleton or main frame just like the stone plate. 

Thermal insulation structure in this situation is similar to what we do in stone curtain wall.

■ 预制外墙夹芯保温构造 预制混凝土复合保温夹芯墙板是一种高效节能外墙产品，具有防火、防 水、节能、耐久

等优点，两层混凝土板之间的连接件及其构造是该产品的 关键技术，实施时应论证方案并制订技术质量保证措施。

PC external wall sandwich-thermal-insulation structure

Sandwich PC panel (insulation in between) technology is very good for external wall. The wall performs well in th

ermal insulation, anti-fire, waterproof, energy saving and durability. The key of this system lies in the connecter and 

its structure. When using this technology, we should design the plan and make quality control measures.
