目前,大部分建筑物为了减轻钢筋砼框架、框剪结构楼体的荷载,填充围护墙多采用轻质砌块、砼空心砌块等。这些材料具有容重轻、隔热保温性能好、施工方便,且能降低工程造价等优点。但在使用过程中,常出现外墙渗漏造成质量通病,如外墙面上出现片片的湿印迹,使外墙面层脱落开列、空鼓,室内墙面变色、发霉、涂料起皮,面层起粉,严重地影响了建筑物的使用功能。分析各方面原因造成的渗漏水通病,阐述相应的防治措施,根除渗漏水通病,提高工程质量。 At present, in order to reduce the load on most of the buildings, such as reinforced concrete frames and frame shear structures, light-weight concrete blocks, concrete hollow blocks and the like are often used to fill the wall. These materials have the capacity of light weight, good insulation properties, construction convenience, and can reduce the cost of construction. However, in the process of using, leakage of the outer wall often causes common defects in quality. For example, a wet blot of a chip appears on the outer wall surface to cause the outer wall surface layer to fall off, hollowing out, discoloration of indoor wall surface, moldy, Surface powder, a serious impact on the use of the building functions. Analysis of all causes of leakage of water disease, elaborate the appropriate prevention and treatment measures to eradicate the leakage of water disease, improve the quality of the project.
