摘要: 预制混凝土夹心保温墙板具有良好的经济效益和环境效益,作为低能耗绿色环保的预制墙体,可契合当前建筑产业装配化和住宅建筑节能化的发展趋势,将成为“双碳”目标下建筑业控制碳排放量的有效手段。 介绍了预制混凝土夹心保温墙板的现有研究,对墙板的构造特征、结构性能和设计方法进行归纳总结。 结果表明应将复合度作为衡量墙板结构性能的重要指标并在结构设计中得到体现;应将墙板内连接件性能的退化趋势引入到设计方法中,进而完善结构计算模型;应尽快提出统一设计标准,促进承重式完全复合墙板的发展和应用。

Abstract: Precast concrete sandwich insulation wall panel has good economic and environmental benefits. As aprefabricated wall with low energy consumption and green environmental protection, the sandwich wall panel can fit thecurrent development trend of assembly in the construction industry and energy saving in residential buildings, and itwill become an effective means for the construction industry to control carbon emissions under the goal of " doublecarbon" . The existing research on precast concrete sandwich insulation wall panel was introduced, and the structuralcharacteristics, structural performance, and design method of the wall panel were summarized. The results show thatthe degree of composite action should be an important index to measure the structural performance of the wall panel andshould be reflected in structural design. The degradation of the connector property should be introduced into the designmethod of the sandwich wall panel, and further improves the calculation model of structural. The unified designstandard also should be put forward to promote the development and application of load-bearing and fully-compositewall panel.

Keywords: precast concrete sandwich insulation wall panel; emission peak; carbon neutrality; load-bearing andfully-composite wall panel; degree of composite action; degradation of connector property
