摘　　要：为解决现有建筑能耗中由墙体引起的热损失问题,本文提出一种暗肋夹芯式复合轻质保温墙板,并围绕该种新型墙板的热工性能开展研究。首先分别测试轻骨料混凝土、聚苯颗粒混凝土的热工参数,研究内外叶及芯层不同厚度组合、内置钢筋网及平面桁架对复合墙板热工性能的影响。然后将试验结果与理论分析结果进行对比,验证理论分析模型的可靠性,为复合保温墙板的热工设计提供基础研究支撑。对比常规预制混凝土外墙板,新型复合墙板表现出良好的热工性能。In order to solve the problem of heat loss caused by wall in the existing building energy consumption,a kind of dark ribbed sandwich precast composite lightweight insulation wall panel was proposed in this paper,and the thermal performance of this new type of wall panel was studied.First,the thermal parameters of lightweight aggregate concrete and polystyrene granular concrete were tested respectively,and the effects of different thickness combinations of inner and outer blades and core layers,built-in steel mesh and plane truss on the thermal performance of composite wall panels were studied.Then the experimental results are compared with the theoretical analysis results to verify the reliability of the theoretical analysis model,and provide fundamental research support for the thermal design of composite insulation wall panel.Compare with the conventional precast concrete wallboard,the new composite wallboard shows good thermal performance.
