摘要
和厨房相通的冷阳台窗台冬季发生冻害是一种常见的现象。经过若干次冻融循环后,这种窗台的砂浆面层及部分混凝土会因冻胀破坏开始脱落。分析了这种窗台冻胀作用的机理,并根据应力分析对裂缝走向进行了解释,而后对发生冻害的窗台给出了简易处理措施。
The sill of cold balcony which is damaged by frostbite in winter owing to connecting with kitchen is a common phenomenon. After several freeze-thaw cycles,the cement mortar and some concrete will begin to fall because of frost heaving.This paper analyzed the mechanism of frost heaving of sill,explained the orientation of crack according to stress analysis,and simply dealt with the sill of frostbite by frost heaving.
