三和花园B区8栋17层框架剪力墙结构住宅楼,总建筑面积为91000m2。屋面工程根据设计要求,采用防滑地砖发泡聚氨酯倒置式上人屋面,防水按Ⅱ级设防。考虑本工程的重要性,屋面采用50mm厚硬泡聚氨酯防水保温层,既可以发挥良好的保温隔热功能,又可以利用硬泡聚氨酯的防水性能,对防水层起到设防作用。本工程使用硬泡聚氨酯防水保温层的面积为6000m2,具体做法如图1所示。
Sanhe Garden B District 8 17-story frame shear wall structure residential buildings, with a total construction area of 91000m2. Roofing According to the design requirements, the use of non-slip floor tile polyurethane foam upside down roof, waterproof by Ⅱ level fortification. Considering the importance of this project, the roof is made of 50mm thick rigid polyurethane foam waterproof insulation layer, which can not only exert good thermal insulation function, but also utilize the waterproof performance of rigid polyurethane foam to play a fortification role in the waterproof layer. The project uses hard foam polyurethane waterproof insulation area of 6000m2, the specific approach shown in Figure 1.
