摘　　要：混凝土夹芯复合墙板是一种自保温复合墙板,选取6组墙板进行热工实验,实验结果表明:墙板的传热系数随斜向钢筋含量和保温层厚度的变化规律与理论分析结果相似,能满足节能设计标准。另外,穿过保温层的斜向钢筋具有明显的"热桥"效应,但其效应相比理论分析要小。研究成果与实际工程联系紧密,具有很强的实用价值。The reinforce-concrete sandwich wall-panel is a kind of self-insulation sandwich wall-panel. Six groups of wallpanel were chosen for experiment on the heat engineering characteristics in this paper. The experiment results indicate that influence on heat engineering characteristics of reinforce concrete sandwich waU-panel,due to the different thickness of heat insulation layer and the ratio of oblique tie bar, are similar to results of the theoretical analysis and can meet with the standard of energy conservation. Moreover, the oblique tie bar through the heat insulation layer has obvious effect of ＂heat bridge＂,but its effect is less than the theory. The findings of this paper are tightly related to the practical engineering and have high use value.
