摘要：

针对严寒地区现浇混凝土保温结构施工技术,在传统施工技术基础上对内置保温板构件的尺寸控制、层间连接方式及混凝土浇筑技术进行优化. 针对内置保温板墙体进行热工性能分析,采用 Airpak3. 0 软件对热流密度变化进行模拟分析. 结果表明,优化后的定额基价仅为 20. 68 元/ m2,相比于传统施工技术减少了 18. 97 元/ m2.同时,连接件布置越密集,综合修正传热系数越大. 当板厚为 80mm 时,连接件为 9 个/ m2 的综合修正传热系数高达 1. 468,而连接件为 6 个/ m2 的综合修正传热系数仅为 1. 363. 该优化不仅提升了建筑物的保温性能和施工效率,还实现了成本的有效控制.

In view of the construction technology of cast⁃in⁃place concrete thermal insulation structure insevere cold area, the size control, interlayer connection mode and concrete pouring technology of built⁃inthermal insulation board members are optimized on the basis of traditional construction technology. Thethermal performance of the built⁃in insulation board wall was analyzed, and the change of heat fluxdensity was simulated and analyzed by Airpak3. 0 software. The results show that the fixed base price ofthe optimized construction technology is only 20. 68yuan / m2, which is 18. 97yuan / m2lower than that ofthe traditional construction technology. At the same time, the more dense the layout of the connectors,the greater the comprehensive correction heat transfer coefficient. When the plate thickness is 80mm, thecomprehensive correction heat transfer coefficient of the connector is 9 / m2is as high as 1. 468, while thecomprehensive correction heat transfer coefficient of the connector is 6 / m2is only 1. 363. Theoptimization not only improves the thermal insulation performance and construction efficiency of thebuilding, but also achieves effective cost control.
