摘　　要：建立了构造柱热桥的数学模型 ,利用有限元方法 ,对住宅建筑构造柱热桥散热量及构造柱热桥内表面温度进行了计算与分析 ,绘制了热桥部位温度分布与热流分布图 ,对五种构造柱热桥内表面温度进行了比较 ,给出了热桥的最佳节能构造做法 ,提出了达到建筑节能 5 0 %及 6 5The mathematical model of the constructional column thermal brigdge is set up in this paper.Calculation and analysis of the constructional column thermal bridge of residential building are carrried out for the heat distribution by means of finite element method.The temperature and heat flux distribution of the thermal bridge are plotted.Five kinds of thermal bridge are compared with each other,and the optimum bridge construction method is suggested for energy conservation.Measures are put forward to meet the goal of 50～65 percents energy conservation.
