建筑外墙保温技术虽已得到广泛应用,但在具体施工过程中,由于受材料特点、施工工艺、关键技术、施工组织、建筑物结构形式、气候变化等多方因素的限制,很容易在建筑产品交付使用一段时间后甚至于在施工过程中,陆续出现墙体保温层脱落、墙体保温层开裂、墙体装饰面涂料脱落或龟裂、保温层渗水等质量问题,轻则影响建筑物外部美观,重则丧失节能效果,甚至于危及人身安全。聚苯板具有质地轻、保温隔热效果好、施工工艺成熟、质优价廉等特点是目前建筑物节能环保中技术成熟、工艺可靠、易操作的保温系统,其实践应用也越来越广泛。本文以聚苯板外墙保温施工为例,重点阐述施工技术质量控制以及质量缺陷防治措施。
Although the exterior wall insulation technology has been widely used, but in the specific construction process, due to material characteristics, construction technology, key technologies, construction organization, building structure, climate change and other factors, it is easy to build products After delivery for a period of time even in the construction process, gradually appeared wall insulation shedding, wall insulation cracking, wall decorating paint peeling off or cracking, insulation water seepage and other quality problems, ranging from affecting the external appearance of the building , While losing energy efficiency, even endanger personal safety. Polystyrene board with light texture, good thermal insulation effect, the construction process is mature, high quality and low price and other characteristics of the current building energy saving technology is mature, reliable technology, easy operation of the insulation system, the practical application is also more and more widely . In this paper polystyrene foam wall insulation construction as an example, focusing on the construction technology quality control and quality defects prevention and control measures.
