摘要

基于嘉兴地区主流墙体构造,模拟墙体表面温度分布,分析了主体墙传热系数与热桥线传热系数的相关性,研究了热桥效应对墙体保温性能的影响。提出了在节能建筑墙体设计时,在满足墙体保温性能同时,不应只重视主体墙的保温,还要考虑热桥部位保温构造,使主体墙与热桥柱的传热系数相近,避免墙体外表面开裂现象。
        Based on the mainstream wall structure in Jiaxing area, the temperature distribution on the wall surface is simulated. The correlation between the heat transfer coefficient of the main wall and the heat transfer coefficient of the heat bridge line is analyzed and the influence of the heat bridge effect on the thermal insulation performance of the wall is studied. It is pointed out that in the design of energy-saving building wall, not only the heat preservation of the main wall should be paid attention to, but also the thermal insulation structure of the hot bridge should be considered, so that the heat transfer coefficient between the main wall and the thermal bridge column is similar to avoid cracking on the outer surface of the wall.
