摘要
叙述外墙外保温系统的多层复合技术,说明其构造的合理性、适用性和裂缝产生的可能性。提出在"抗放结合,以放为主"原则下,以材料性质逐层渐变、变形应力逐层释放的手段,采取减小层间约束,增强材料延性,邻层材料变形求相近、匹配相容求相宜,分隔设缝、防水透气等措施,以达到控制裂缝的目的。
Multilayer composite technology of exterior thermal insulation system of external wall is introduced herein, and rationality and applicability of this technology and possibility for generation of cracks are explained. On principle of prevention and release, measures are adopted to reduce constraint between layers,improve ductility of material, realize similar material deformation between adjacent layers, adopt different matching consistency, set isolation joints and improve waterproof property and air permeability, so as to control cracks.
