摘　　要：通过ANSYS Workbench软件,对建筑物外墙的混凝土中柱与蒸压加气混凝土砌体间的热桥效应进行了分析。确定了不同情况下采用B05级高性能蒸压加气混凝土砌块砌筑的外墙厚度,并进行外墙内表面结露及房间基本热舒适验算。计算了当混凝土中柱外贴不同材质、不同厚度的保温板时,外墙及混凝土柱模型的温度、热流密度分布情况,以及混凝土中柱热桥影响区域长度和热桥影响区域内热损显著程度作用规律。In this paper,the ANSYS Workbench software is used to analyze the thermal bridge effect between the concrete center column of the exterior wall of the building and the autoclaved aerated concrete masonry.The thickness of the outer wall built with B05 high-performance autoclaved aerated concrete blocks under different conditions was determined,and the condensation on the inner surface of the outer wall and the basic thermal comfort check of the room were determined.In addition,the temperature and heat flux density distribution of the outer wall and concrete column model when the concrete central column is pasted with insulation boards of different materials and different thicknesses are calculated.There are also concrete middle column thermal bridges affecting the length of the area and the degree of heat loss in the thermal bridges affecting the area.
