在砖混住宅建设施工中,为解决外墙渗漏这一常见的质量通病,近年来提出了许多措施,在提高质量方面也有了一定的改善。实践证明,要想搞好外墙防渗漏工作,必须抓好施工中的各上环节。1.外墙渗漏的原因1.1砌体材料不合格。砖混结构常用实心粘土砖或多孔砖作为砌体材料,尽管其抗压强度符合要求,但在施工中对外观 In the construction of brick-concrete dwellings, in order to solve the common quality problem of leakage of external walls, many measures have been proposed in recent years, and improvements in quality have also been made. Practice has proved that if we want to do a good job in preventing leakage of external walls, we must do a good job in all aspects of construction. 1. Causes of external wall leakage 1.1 Masonry materials failed. The brick-concrete structure is usually made of solid clay bricks or perforated bricks as a masonry material. Although its compressive strength meets the requirements, it has a good appearance during construction.
