前三门大模板高层住宅工程中,外墙均采用大型预制壁板,处理好预制外墙板接缝的防水问题是确保工程质量的重要环节之一、外墙板接缝渗漏原因分析北京地区采用大型预制外墙板建成的装配式房屋,墙板接缝与一般砖墙接缝有很大不同,即预制外墙板接缝普遍存在有裂缝。
In the first three large formwork high-rise residential projects, large-scale prefabricated panels are used for exterior walls, and the waterproofing of prefabricated exterior wall panel joints is an important part of ensuring project quality. The reason for the leakage of external wall panel joints in Beijing is analyzed. In the region, prefabricated houses built with large-scale prefabricated exterior wall panels are used. The seams of wall panels are very different from those of ordinary brick walls, that is, prefabricated external wall panels generally have cracks in their joints.
