摘　　要：热桥为建筑围护结构中保温薄弱部位,阳台板热桥由于其隔断保温层,使得该部位热桥效应格外严重,保温措施也更为复杂。利用数值模拟的方法,针对不同地区的阳台热桥效应进行传热分析和保温效果对比。研究结果表明,在现行的热工标准下,阳台板增设保温层可以降低热桥热损失25%以上。The thermal bridge is the weak part of the building envelope in thermal insulation,and the balcony thermal bridge is the weakest one,which needs to install additional insulation layers.In this paper,we use numerical simulation to analyze the heat transfer and compare the thermal insulation effect for balcony thermal bridge effect in different areas.The research results show that under the current thermal engineering standards,the balcony slab with additional insulation layer can reduce the thermal bridge heat loss by more than 25%.
