预制混凝土夹心保温墙板技术研究进展

Review on the Precast Concrete Sandwich Panels

在“双碳”目标下,集结构、保温和装饰于一体的预制混凝土夹心保温墙板逐渐成为装配式建筑发展的必然趋势。预制混凝土夹心墙板的力学性能一直是研究热点,随着我国对建筑节能要求的提高以及超低能耗概念的深入,墙板的高效保温性也受到学者们的关注。论文对预制混凝土夹心保温墙板的平面外抗弯和平面内抗剪切的相关研究工作进行总结,探讨分析近年来墙板保温效率的进展,提出现阶段的研究重点以及发展的方向。

Precast concrete sandwich panels(PCSPs)with multiple functions has gradually become popular under the goal of“double carbon”,the mechanical performance of the PCSPs has always been a hot topic of the research,the thermal performance of PCSPs has also attracted more attention with the development of the standard for energy efficiency of buildings and the deepening understanding of ultra-low energy consumption concept.This paper summarizes the related research work of bending and shearing resistance of PCSPs,discusses the progress of the insulation efficiency,and puts forward the current research and development direction.On this basis,providing the ideas for PCSPs designing and application of PCSPs in ultra-low energy consumption buildings.
