指出建筑结构外侧保温层的双层模板构造工艺复杂、费工费时、造价较高，存在一定弊病，通过对 SJN 复合保温板代模板技术进行技术性能、操作步骤和经济指标的对比分析，事实证明，采用合适的设计方法，利用 SJN 复合保温板代替传统建筑模板可以有效降低工程造价，节省工期。%The paper points out defects of double-layer template structure of external building insulation layer,such as complicated structure, long construction duration and high cost. It comparatively analyzes technical performance,operation steps and economic index of SJN composite insulation plate. Practice proves that:applying SJN composite insulation template replacing traditional building template can not only reduce en-gineering cost but also shorten construction duration by applying suitable design methods.
