摘　　要：文中利用PTemp二维传热计算软件对装配式住宅嵌入式外墙中柱的热桥进行了二维传热分析,对比分析不同断桥保温构造对外墙平均传热系数的影响。结果表明外保温加内保温断桥构造保温效果会更好,内保温体系热桥处热损较大。Two-dimensional heat transfer model is established by the PTemp software to analyze the thermal bridge of the embedded exterior wall of the prefabricated house.Moreover,the influence of different broken bridge insulation structures on the average heat transfer coefficient of the exterior wall is compared and analyzed.The results show that the thermal insulation effect of the external thermal insulation combined with internal thermal insulation broken bridge structure has good performance with more the thermal loss of the thermal bridge of the internal thermal insulation system.
