【摘要】：在国外,墙体保温技术已是一个相对成熟的建筑节能技术,而在中国,墙体保温技术处于起步和发展阶段,在实际工程中出现了许多墙面裂缝等有待解决的技术质量问题。中国拥有世界最大的建筑节能的市场,这为各种建筑节能技术在中国的快速进步提供了基础和保障;我国的设计单位、施工单位和科研单位愈来愈看重解决墙体保温这一质量通病,其中建筑外墙外保温系统面层防裂就是一个重要的技术领域,这一技术的发展对我国建筑节能技术的发展具有重大意义。在这一背景下,我们对以唐山为代表的寒冷地区典型的工程实施进行了实地调查和研究,针对工程施工、材料和构造设计等诸因素的影响,总结分析了建筑外墙外保温系统面层产生裂缝的因素和预防裂缝产生的技术措施。通过深入调查研究唐山市外墙外保温工程项目后,确定了相对适用于寒冷地区的、目前常用的建筑外墙外保温体系控制裂缝的技术措施和技术理念。建筑外墙外保温做法与外墙内保温系统相比更具优势;建筑外墙外保温各个构造层应该具有良好的配套性能;对建筑节能市场加强管理,完备不同区域建筑外墙外保温技术规程的制定。并且从构造设计、材料及施工等方面对唐山地区建筑外墙外保温系统面层裂缝防裂措施和产生原因进行了深入的探讨和研究,对建筑外墙外保温系统面层抗裂技术的进步具有重大的指导意义,并且为建设行业监管部门提供了建设性意见。
[Abstract]:In foreign countries, wall insulation technology is a relatively mature building energy saving technology, but in China, wall insulation technology is at the beginning and development stage, there are many technical quality problems to be solved in actual engineering, such as wall cracks. China has the largest market for building energy conservation in the world, which provides the foundation and guarantee for the rapid progress of various building energy-saving technologies in China. Construction units and scientific research institutions are paying more and more attention to solving the common quality problem of wall insulation, among which the crack prevention of the surface layer of the external thermal insulation system of the building's external wall is an important technical field. The development of this technology is of great significance to the development of building energy saving technology in China. In this context, we have carried out a field investigation and study on the typical engineering implementation in the cold area represented by Tangshan, aiming at the influence of engineering construction, material and structural design, etc. This paper summarizes and analyzes the factors causing cracks in the external insulation system of building exterior wall and the technical measures to prevent the cracks. Based on the investigation and study of the exterior wall thermal insulation project of Tangshan City, the technical measures and technical ideas of controlling cracks in the external thermal insulation system of building wall which are relatively suitable for the cold area are determined. The method of external insulation of external wall of building has more advantages than internal insulation system of external wall; each layer of external insulation of external wall of building should have good supporting performance; strengthen the management of energy saving market of building, Complete the establishment of external thermal insulation technical regulations for different regions of buildings. And from the structural design, material and construction, the crack prevention measures and causes of the external insulation system of the exterior wall in Tangshan area are deeply discussed and studied. It is of great guiding significance to the progress of anti-cracking technology of exterior insulation system of building exterior wall, and it also provides constructive suggestions for the supervision department of construction industry.
