高层住宅现浇混凝土外墙无网浇合外保温体系

在国内首次开发了高层住宅现浇混凝土外墙无网浇合外保温体系。该体系采用无钢线网架的聚苯板为保温板，抗裂层由聚合物水泥砂浆及耐碱破纤网格布组成，再用塑料胀管锚固，经聚苯板与混凝土粘合力、塑料胀管抗拔力、压缩率及抗冻试验表明该体系性能可靠、安全度高，热工测试表明满足北京市《节能细则》对墙体节能50%的要求，造价低、工效高，综合造价比后挂有网体系降低40%～50%。

Non-net casting exterior thermal insulation system on field concrete exterior wall in high storeyed resident building

The non - net casting exterior thermal insulation system on field concrete exterior wall in high storeyed resident building is developed firstly at home. This system adopts polystyrene board without steel wire net as thermal insulation board. The cracking resistant layer consists of polymer cement mortar and alkali resistant glass fiber woven scrim, anchored with plastic expanded tube. The tests of bonding power between polystyrene board and concrete, plastic expanded tube pull- out, compressibility, freeze resistance show the system property is reliable and high safe. The thermal measurement test shows the system can meet the requirement of wall body energy - saving 50% stipulated in Beijing "Energy Saving Detailed Regulations", with low construction cost and high work efficiency. The comprehensive construction cost lowers 40%～50% in comparison with back suspending net system.
