Study on pore optimization design of hollow block based on ANSYS

烧结保温空心砌块是建筑节能的一个重要的研究方向,通过ANSYS研究不同因素对烧结保温空心砌块热工性能的影响,结果表明:在保证砌块力学性能的前提下,沿热流传递方向,增加孔洞长宽比、孔排数、孔洞率、孔肋延长线系数,减小孔列数、孔洞间距均能改善砌块的保温隔热性能。自行设计的孔型优化结构,模型C完全符合国家标准中孔型孔结构及孔洞率的相关要求,且理论上抗压强度相对较好,导热系数为0.1508W/(m·K),满足单一节能烧结类墙体材料节能65%的目标要求;且生产实践便利,可为生产实践提供有效的理论指导。

In this paper,the influence of different factors on the thermal performance of fired insulation hollowblock is studied by ANSYS.The results show that under the premise of ensuring the mechanical properties of theblock,the thermal performance of the block can be improved by increasing aspect ratio of pores,numbers of pores,pore rate,pore extension line coefficient and pore spacing.The model C fully complies with the requirements of thepore structure and porosity in the national standard,and the theoretical compressive strength is relatively good,thethermal conductivity is 0.1508 W/（m·K）,satisfying the target requirement of 65% energy saving on single fired wallmaterial,and provide effective theoretical guidance for production practice.
