目前砖混结构的外墙保温节能措施从构造上可分为内保温、夹心保温和外保温三种类型。应用较为广泛的是内、外保温这两种。我国目前采用的绝大部分是内保温,而国外则是外保温。相比之下,外保温比内保温更合理(表1)。它可以降低墙体的热应力,彻底克服热桥、结露等内保温无法克服的危害,并利于冬季保温与 At present, the external wall insulation energy-saving measures of brick-concrete structure can be divided into three types: internal insulation, sandwich insulation and external insulation. The application of a wide range of internal and external insulation are two kinds. The vast majority of China’s current use is internal insulation, and foreign is external insulation. In contrast, external insulation is more reasonable than internal insulation (Table 1). It can reduce the thermal stress of the wall, completely overcome the damage that the internal thermal insulation such as the thermal bridge, condensation, etc. can not overcome, and is conducive to winter insulation and
