外墙渗水是建筑质量的一种通病,以外墙镶贴面砖的工程发生的较多。究其原因,除了施工操作技能低外,还有思想上只注重外墙外观效果,忽视外墙渗水的预防,从而留下外墙渗水的隐患。其返修处理也较困难。外墙面悬空,在返修时一般用吊篮施工,操作不方便。在返修时也很难一次找准渗水点,需要反复修补才能根治,浪费人力物力。因此,外墙渗水的通病治理要以预防为主,施工中严格监督,严格对工程质量和工序质量的检查,防患于未然,将质量事故消灭于萌芽状态中。
External wall seepage is a common problem in construction quality. There are many projects involving veneered bricks. The reason is that in addition to the low skills of construction operations, there is also an ideological focus on external wall appearance effects, neglecting the prevention of external wall seepage, thus leaving the hidden danger of external wall seepage. Its repair process is also more difficult. The outer wall is vacant, and it is generally inconvenient to use a hanging basket for construction during repairs. It is also very difficult to identify the water seepage point at the time of repair. It requires repeated repairs to cure it and waste human and material resources. Therefore, the prevention of common problems of seepage of external walls should be based on prevention, strict supervision during construction, strict inspection of project quality and process quality, prevention of problems, elimination of quality accidents in the bud.
