两种典型自保温墙体经济性分析

Economic analysis of two typical self-insulating walls

随着建筑外墙保温技术的发展,由于墙体外保温、内保温的局限性和墙体自保温技术的优越特性,墙体自保温技术越来越受到各界的重视,以夏热冬冷地区典型城市南京为例,通过对蒸压加气混凝土砌块外墙和陶粒混凝土复合砌块外墙这两种市场使用率较高的外墙墙体进行计算,得出夏热冬冷地区相同节能效果下墙体的单位面积造价,比较分析后,证明蒸压加气混凝土砌块自保温外墙墙体具有更好的经济性。

With the development of building external wall thermal insulation technology, wall self-insulation technology has received more and more attention from because of the limitations of wall external insulation and internal thermal insulation, and the superior characteristics of wall self-insulation technology. This thesis takes Nanjing, a typical city in hot summer and cold winter regions as an example, to conduct related calculation of the external walls of autoclaved aerated concrete block outer walls and eeramsite concrete composite block external walls which are used in high market rates. The cost per unit area of the wall under the same energy-saving effect in hot summer and cold winter regions was compared and analyzed, which proved that the autoclaved aerated concrete block has better economy from the external wall of the thermal insulation wall.
