装配整体式混凝土建筑防水技术及工程应用

Waterproofing Technology and Engineering Application for Assembled Monolithic Concrete Building

对天津首例装配整体式混凝土建筑工程——双青新家园20号地8号楼的防水工程进行了介绍。外墙板的垂直缝和水平缝采用结构防水与材料防水相结合的防水做法,上下墙板的保温层中间设置止水胶条,有效地保证了工程防水效果。利用座浆料和灌浆料解决了保温板与混凝土板之间存在缝隙的问题。此外,还介绍了叠合楼板、窗洞口、主要细部节点等处的防水技术。

The article introduces the waterproofing work of building No.8 of Shuangqingxin Homeland the first assembled monolithic concrete building project in Tianjin. The vertical and horizontal joints of external wall panel adopts structure waterproofing combining material waterproofing. Water stop strip is installed between the insulation layers of upper and lower wall panels, which guarantees the waterproofing effect successfully. The joint issues between insulation board and concrete panel are solved by using block slurry and grouting material. Moreover, the article also introduces waterproofing technology for composite floor slabs, window opening and other major details.
