本文首先介绍了热桥的定义、热桥在建筑中的主要表现形式以及热桥对建筑能耗和墙体结露的影响。接着,就建筑热桥的数学建模、数值分析、实验方法等不同研究手段进行了回顾总结,同时对国内外关于建筑热桥的防范解决措施及研究难点的现状进行了阐述。最后,针对多因素作用下的热桥分析、新形式热桥研究、计算模型简化、热桥防护等领域的新方向及突破点进行了展望。

Firstly, this paper introduces the definition of thermal bridge, the main forms of thermal bridge in building and the influence of thermal bridge on building energy consumption and wall dew. Then, this paper reviews and summarizes the mathematical modeling, numerical analysis and experimental methods of the thermal bridge, and expounds the present situation of the preventive measures and research difficulties of the thermal bridge at home and abroad. Finally,the new direction and breakthrough point in the field of thermal bridge analysis, new form thermal bridge research,simplified calculation...
