近年来,加气混凝土制品在我国各地已经得到了广泛的应用。在应用中出现了一些问题;如墙体裂缝、板材保护层脱落、屋面漏雨、砌体在窗台以下大片剥落、外墙内表面结露等现象。是什么原因使加气混凝土制品在应用中出现上述问题呢?有无防止办法呢?本人对此提出一点拙见。 一、设计与施工方面的因素: 随着加气混凝土应用技术的发展,国家建设部于一九八四年颁发了《蒸压加气混凝土应用技术规程》(JGl7—84),北京建筑设计院编制了《加气混凝土应用技术参考图集》,北京建筑设计院、东北建筑设计院编辑的《加气混凝土在建筑上的应用》一书,早已由建筑工业出版社出版。但由于设计和施工单位,对加气混凝土这种新型材料认识不足,仍然沿用了许多传统的构造作法,是
In recent years, aerated concrete products have been widely used throughout China. There are some problems in the application; for example, cracks in the wall, falling off of the protective layer of the sheet, leakage of the roof, large flakes of the masonry below the window sill, and condensation on the inner surface of the outer wall. What are the reasons for the above problems in the application of aerated concrete products? Is there any way to prevent it? I. Design and Construction Factors: With the development of aerated concrete application technology, the Ministry of Construction issued the Technical Regulations for Autoclaved Aerated Concrete in 1984 (JGl7-84). Beijing Institute of Architectural Design A book called “Atlas of Applied Aerated Concrete Technology” was compiled. The book “Application of Aerated Concrete in Buildings” edited by Beijing Architectural Design Institute and Northeast Architectural Design Institute has been published by Construction Industry Press. However, due to lack of understanding of the new type of material, aerated concrete, due to the design and construction units, many traditional construction methods are still used.
