笔者根据使用聚乙烯复合防水卷材经验 ,总结提出一种新的屋面构造。该构造采用聚乙烯复合卷材作主防水层 ,利用聚合物水泥砂浆将其与钢筋混凝土基层粘贴 ,二者亲和性好 ,可以在潮湿基面上操作 ,因而气候环境对施工质量影响不大。针对用聚乙烯复合材料在保温层上做防水层并用２ Based on the experience of using polyethylene composite waterproofing membranes, the author summarizes and proposes a new roofing structure. The structure uses a polyethylene composite membrane as the main waterproof layer, using polymer cement mortar to paste it with the reinforced concrete base layer, the two have good affinity, can operate on the wet base surface, so the climate environment has little effect on the construction quality . For the use of polyethylene composites in waterproof insulation layer and use 2
