安徽省典型外墙免拆复合保温模板厚度的选择

Selection of Thickness of Typical External Wall Dismantle Free Composite Insulation Template in Anhui Province

为了确定安徽省典型外墙免拆复合保温模板保温层的合理厚度,以安徽省合肥市中铁四局机关大院北区拆迁改造项目为背景,结合安徽省当地的气候条件确定了外墙结构传热系数,对XPS板、EPS板和岩棉板模板3种保温材料进行了分析,分析结果表明,在相同的节能标准条件下,XPS板经济性能最好,且合理厚度为30 mm。

In order to determine the reasonable thickness of the insulation layer of the typical external wall dismantle free composite insulation template in Anhui Province,based on the demolition and reconstruction project in the north area of the office compound of the China Railway Fourth Bureau in Hefei,Anhui Province.The heat transfer coefficient of external wall structure is determined according to the local climate conditions in Anhui Province.And the three types of insulation materials,XPS template,EPS template and rock wool template were analyzed.The analysis results showed that under the same energy-saving standard conditions,the reasonable thickness of XPS template is 30 mm and the economic performance is the best.
