A SIMULATION ANALYSIS ON THERMAL PERFORMANCE OF A NEW TYPE PREFABRICATED CONCRETE FLOOR SLAB

摘要: 针对一种新型装配式混凝土楼盖,采用ANSYS有限元分析方法,研究此楼盖的传热特点和热工性能。分析结果表明:楼盖由于具有特殊的肋格构造形式,使得楼盖平面内的热流密度分布与表面温度分布很不均匀;楼盖的保温隔热性能优于厚度相同的常规装配式混凝土叠合楼盖;填充材料的类型直接影响了楼盖的保温隔热性能。Abstract: A new type prefabricated concrete floor slab was studied in the paper. Through the finite element analysis method, the heat transfer characteristics and thermal performance of the panel were studied. The results showed that the rib grid of the floor slab could cause the uneven distribution of thermal flux and surface temperature; the thermal insulation performance of the floor was better than that of the typical concrete composite floor with same thickness; the thermal insulation performance of the floor slab could be changed with different filling materials.
