近几年来,内浇外挂住宅在住宅建设中发挥了很大的作用,但是,在施工过程中,由于忽视了施工质量,没有严格按照设计要求进行施工,结果出现了漏水问题,有的住宅漏水还相当严重。我们对北京市、唐山市一些漏水的内浇外挂住宅调查结果表明,内浇外挂住宅的构造防水允许少量水进入墙缝空隙内,然后再用排水管将空腔内的水排出。可是,有些住宅在施工时,将外墙缝用砂浆完全堵死,致使进入缝内的水无法排出,而沿着
In recent years, cast-in-place dwelling houses have played a large role in the construction of houses. However, in the construction process, due to the neglect of construction quality, construction was not strictly carried out in accordance with the design requirements. As a result, there was a leakage problem and some houses leaked water. Still quite serious. Our survey results of some leaking in-house pour-out dwellings in Beijing and Tangshan indicate that the structural waterproofing of the pourable external dwelling houses allows a small amount of water to enter the gaps in the wall joints, and then drain the water in the cavity with a drainage pipe. However, when some houses are under construction, the outer wall joints are completely blocked with mortar, so that the water entering the joints cannot be discharged, but along the
