摘　　要：文章介绍了热桥及其对结构的危害性,基于导热微分方程的基本理论,利用ANSYS有限元软件对玻化微珠保温砂浆外保温墙体和无保温墙体热桥的温度场和热流密度进行了分析。This paper introduces the thermal bridge and to the dangers of structure. Based on the thermal conductivity of the basic theory of differential equation by using ANSYS finite element analysis software,the glazed hollow bead mortar of external insulation wall and no insulation wall which temperature field and heat flux density of the thermal bridge were studied. The results show that both the junction temperature and heat flux happened mutations when thermal bridge site within less than filling wall surface temperature,Using glazed hollow beads insulation material can improve thermal bridge surface temperature of the area,and conducive to the durability of the main structure. Therefore,glazed hollow beads insulation material of external thermal insulation can solve the problem of thermal bridge structures,the realization of energy- saving building 65% standard is an ideal insulation material.
