摘　　要：渗漏是建筑幕墙普遍存在的质量问题,在一定程度上影响建筑结构使用性能,且渗漏问题通常难以有效根治。依托近40个在建或已竣工幕墙工程,对幕墙渗漏原因进行综合分析,介绍常见的幕墙渗漏检测技术,并对红外热成像技术实际应用进行叙述。幕墙渗漏原因主要有密封胶漏打或开裂、胶条安装问题或失效、窗口塞缝过大及开启窗组角连接问题,需充分考虑设计方案中防渗漏功能的有效性,选择适合施工环境的材料,加强材料加工和施工阶段的质量控制,并定期进行检测和维护工作,及时对渗漏部位进行处理。Leakage is a common quality issue in building curtain walls,which affects the performance of building structures to a certain extent,and is usually difficult to effectively eradicate.Based on nearly forty ongoing or completed curtain wall projects,this paper comprehensively analyzes the causes of curtain wall leakage,introduces common detection technologies for curtain wall leakage,and describes the practical application of infrared thermal imaging.The main causes of curtain wall leakage include missing or cracked sealant application,issues or failure of gasket installation,excessive window joint gaps,and problems with the corner connections of operable windows.It is necessary to fully consider the effectiveness of the anti⁃leakage function in the design scheme,choose materials suitable for the construction environment,strengthen quality control during material processing and construction stages,and regularly carry out detection and maintenance work to promptly address leakage areas.
