温度裂缝是指由于温度的变化而使由几种线胀系数不同的建筑材料和构件构成的建筑物产生不均匀的伸缩而出现的裂缝。温度变形引起建筑物裂缝是常见的质量通病。安徽省属大陆性气候，四季分明、气温变化比较大，冬、夏温差达50℃左右。夏季，在阳光的直射下，有些地区的屋盖温度 Temperature cracks refer to cracks that occur due to non-uniform expansion and contraction of buildings made of building materials and components with different linear expansion coefficients due to changes in temperature. Temperature deformation caused by building cracks is a common quality problem. Anhui Province has a continental climate with four distinct seasons and relatively large temperature changes. The temperature difference between winter and summer is about 50°C. In summer, under the direct sunlight, the roof temperature in some areas
