沥青油毡卷材屋面的起鼓问题是一项长期以来未得到彻底解决的质量通病,也是引起屋面渗漏的主要原因之一。起鼓多发生在卷材铺设后一年左右,但有些在夏季施工、基层含水量又较高的屋面,卷材铺设后一个月内即会产生起鼓,以后鼓泡逐渐扩大甚至相互连片一经外界撞击或由于内压过高而爆裂,屋面即产生渗漏。同时,卷材起鼓是屋面施工时诸多质量问题的外在表现,因此,探讨起鼓原因,并采取相应的预控措施,是提高屋面施工质量的有效途径。
The problem of kicking drums from asphalt linoleum roofing is a long-standing quality problem that has not been completely solved, and it is also one of the major causes of roof leakage. Drums often occurred about one year after the coils were laid, but some roofs that were constructed in the summer and had a relatively high moisture content in the grass roots produced drums within one month after the coils were laid. After that, the bubbling gradually expanded or even joined together. Once the external impact or burst due to high internal pressure, the roof will leak. At the same time, the drum kicking is an external manifestation of many quality issues during the construction of the roof. Therefore, it is an effective way to improve the quality of the roof construction by exploring the causes of the drums and adopting appropriate pre-control measures.
