摘要
目前国内外墙保温作法
主要是外墙外保温
而外保温存在无法与建筑同寿命等弊端.依据山西省外墙节能设计要求
结合山西丰富的煤矸石资源
提出了烧结煤矸石多孔砖墙内保温体系.其主要思路是:烧结煤矸石多孔砖墙作主体结构
内抹无机玻化微珠保温砂浆.通过试验与理论计算得到外墙节能的主要指标——外墙平均传热系数
与山西省地方节能标准的规定值进行比较
验证了所提出的内保温体系在山西省的可行性.
Abstract
Thermal insulation practice of domestic external wall
is mainly external thermal insulation of outer walls in which there are shortcomings such as short life at present.Based on the energy saving design requirements of exterior wall in Shanxi province
considering the rich resources of Shanxi coal gangue
the thermal insulation system of coal gangue porous brick walls is put forward.The main idea is that inorganic beads insulation slurry is plastered on the surfaces with coal gangue porous brick walls being regarded as body structure.In addition
energy-saving index of exterior wall that is the average heat transfer coefficient is obtained by the experiments and theoretical calculation.The average heat transfer coefficient of exterior walls compared with local energy-saving criteria of Shanxi province
and so the feasibility of the thermal insulation system in Shanxi province is verified.
