外墙保温构造体系裂缝成因分析

The analysis on crack in the external thermal insulation system of structure

通过对外保温裂缝形成原因的分析,指出温度、材料性能的差异、机械力学特征以及施工是导致裂缝出现的主要原因,并结合外保温构造做法,从设计的角度上提出了外墙外保温墙体避免裂缝产生的几个遵守原则,并分析了上述原则的合理性和可靠性。

Through basic analysis this paper points out that the rebuilding of thermal field and the differences of material performance arc the main reasons for cracking furthermore, it proppses a principles to avoid crack and the available is analysised.
