外墙外保温施工质量问题及防治措施

摘要:目前我国在建筑节能方面已经投入了相当的人力、财力和物力资源,并已取得了一定的成绩;但研究工作主要限于建筑节能技术和建筑节能政策方面,对于建筑施工阶段的质量管理和控制仍关注不足。本文重点研究节能建筑外墙外保温的施工管理过程。外墙外保温,是指在垂直外墙的外表面上建造保温层。此种外保温,可用于新建墙体,也可以用于既有建筑外墙的改造。我国的外墙外保温市场正在日益繁荣,外墙外保温也正在成为我国的一项重要的基本的建筑节能技术。近年来在我国随着国家对民用建筑节能标准的强制执行,因此对建筑外墙保温材料的使用越来越普及。本文主要使用的是EPS板为主要保温隔热材料,这类新型材料在建筑界的推广及应用比较普遍。但这种新型的保温材料在使用过程中也曝露出诸多质量问题,其中,墙面开裂问题是外墙保温的一大通病,造成这种问题的因素很多。例如出现了饰面层脱落、空鼓、开裂、室内返霜、结出水珠等质量问题。作者从施工质量问题入手,寻找其中的施工质量问题,并针对这一系列的质量问题,提出了防治措施。对提高节能建筑外墙外保温施工的质量管理水平大有卑益。

Abstract: at present our country building energy efficiency has put a human, financial and material resources, and has made some progress; But research work mainly limited to building energy conservation technology and building energy policy, for building construction stage of quality management and control is still insufficient attention. This paper focuses on the research of energy-saving building exterior insulation construction management process. Exterior insulation, it is to point to in vertical wall built on the appearance of insulation layer. This kind of external thermal insulation, and can be used in the new wall, also can be used for both exterior transformation. China’s exterior insulation market is growing prosperity, exterior insulation is becoming one of our important basic building energy saving technology. In recent years in China along with the country the civil building energy efficiency standards enforced, so the exterior insulation materials used are increasingly popular. This paper mainly use EPS for main insulation material, this kind of new materials in the construction field for popularization and application is more common. But this new type of heat preservation material also in use process exposure out many quality problem, among them, the metope of exterior wall thermal insulation cracking problem is one of the common failing, cause this problem of many factors. For example appeared act the role ofing, empty drum, fall off the surface cracking, indoor return frost, bearing the quality problem such as water. The authors from construction quality problems, looking for the construction quality problem, and in the light of this series of quality problem, puts forward the prevention measures. To improve the energy saving building exterior insulation construction quality management standards have low profit.
