【摘要】：作为北方地区建筑墙体保温的一种主要形式,XPS板薄抹灰外保温系统在使用过程中普遍存在系统面层开裂现象,严重的甚至出现保温材料脱落,使保温性能丧失。由于XPS板外墙外保温技术的抗裂技术措施还缺少系统的研究,而其相应的的构造设计、施工工艺、施工检验技术以及相关的技术标准更加匮乏,难以保证XPS板外墙外保温工程质量。因此XPS板外保温技术抗裂技术措施特别是严寒地区的抗裂技术措施的研究开发刻不容缓。根据该类系统的构造特点,结合相关文献与工程实践经验,从构造设计、材料特性、施工工艺三方面对系统开裂破坏原因进行了总结分析,得出应从上述三个方面分别采取有针对性的措施,以提高XPS板外墙外保温系统抗裂性能的结论,通过对目前严寒地区外保温系统的应用现状分析,发现粘结、粘结及锚固相结合和现浇系统为工程上常用的外保温系统,本文结合XPS板薄抹灰外墙外保温系统的特点,从外保温系统的构造设计、施工工艺等方面,对其在使用过程中存在的系统面层开裂问题进行了分析,对其相对的抗裂技术措施进行了初探,以提高XPS板外墙外保温系统的性能。
[Abstract]:As a main form of thermal insulation of building wall in northern area, XPS thin plastering external insulation system generally exists the phenomenon of system surface cracking in the process of using, and even occurs serious heat preservation material falling off, which makes the thermal insulation performance lose. Due to the lack of systematic research on the anti-cracking technology of the external insulation technology of XPS plate, the corresponding structural design, construction technology, construction inspection technology and related technical standards are even more scarce. It is difficult to guarantee the quality of XPS board external insulation engineering. Therefore, it is urgent to research and develop anti-cracking technology of XPS plate insulation technology, especially in cold area. According to the structural characteristics of this kind of system, combined with relevant literature and engineering practice experience, the causes of system cracking and failure are summarized and analyzed from three aspects: structural design, material characteristics and construction technology. The paper draws the conclusion that the measures should be taken from the above three aspects to improve the cracking resistance of the external thermal insulation system of XPS board, and through the analysis of the current application situation of the external insulation system in the severe cold area, it is found that the bond is bonded. The combination of bonding and anchoring and cast-in-place system are common external insulation systems in engineering. In this paper, according to the characteristics of external insulation system of XPS thin plastering exterior wall, the structural design and construction technology of external thermal insulation system are discussed. This paper analyzes the cracking problem of the system surface in the process of use, and probes into its relative anti-cracking technical measures in order to improve the performance of the exterior wall insulation system of XPS board.
