随着我国经济水平的不断发展,外墙材料日益更新,从水刷石到马赛克到条砖等,档次快速提升,施工的要求也越高。在主要使用的外墙砖工程中,建筑物外墙渗漏现象比较突出,直接影响建筑工程质量,同时渗漏的产生也影响了建筑物的功能,对室内装饰造成霉烂脱落,影响建筑物的使用。而这些渗漏的产生除了墙体砌筑、外墙砖铺贴不规范、窗台等细部节点构造工程处理不合理等引起外,墙体装饰层开裂即外墙水泥砂浆开裂是造成渗漏的主要原因之一,危害性很大。
With the constant development of our country's economy, exterior wall materials are being updated day by day. From water brushes to mosaics to strip bricks, the grade is rapidly upgraded and the construction requirements are also higher. In the main external wall project, the leakage of the external wall of the building is more prominent, which directly affects the quality of the construction project. At the same time, the leakage also affects the function of the building, causing the interior decoration to fall moldy and affect the building's use. In addition to the emergence of these seepage wall masonry, paving the exterior wall is not standardized, windowsill and other details of the node construction project unreasonable caused, the wall decoration cracking or external wall cement mortar cracking is the main cause of leakage One of the reasons, great harm.
