摘要
目前,我国外墙外保温系统种类多样,防脱落设计方法有待完善,既有建筑外墙外保温系统存在层间黏结强度不足和构造缺陷问题,外墙外保温系统劣化机理、脱落风险识别与评估方法等方面有待进一步深入研究。针对外墙外保温系统剥离机理复杂、劣化程度难以评估、脱落风险不易识别等问题,梳理了外墙外保温系统目前常见的主要构造体系及其防脱落设计方法,统计了外墙外保温系统存在的主要缺陷并探讨了其劣化机理,分析了外墙外保温系统脱落风险识别评估以及修复方法的研究现状。
At present,there are various types of external thermal insulation composite systems(ETICS)used in China and the corresponding anti-peeling design method needs to be improved.Further studies are also needed on the insufficient interlayer bonding strength and the detailing defects,deterioration mechanism,identification and evaluation of falling-off of ETICS.Focusing on the complexity of pealing mechanism and difficulties on evaluating deterioration and identifying falling-off risk,this research summarized the main detailing systems,anti-peeling design method and defect types.The deterioration mechanism was discussed.The research status of falling-off risk identification and repairing method of ETICS was also analyzed.
