The 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.
