AAC砌块自重轻、易切割、防火与保温性好,但其强度低、不能任意加载,开槽开洞局限较多,遇水湿胀且强度和保温性能变低。AAC砌块自由加载墙体施工工艺采用AAC砌块、页岩砖、素混凝土块混墙结构,通过BIM排块设计,在AAC砌块墙体中嵌入素混凝土块,在箱体集中处砌筑页岩砖墙体,以自由地适应加载、开槽开洞和墙体变形;利用表面网膜和界面封堵工艺,较好地解决了防渗防漏;利用砌块墙与页岩砖墙、混凝土梁柱间的厚度差,采用热桥咬合工艺,较好地解决了热桥。该工法系统地解决AAC砌块墙体的质量通病、使用局限,增强AAC砌块墙体的整体性、加载开槽开洞的便易性和防水性能,加上其工厂化生产与加工的特点,使其能更广泛地应用于室内外墙体。 AAC block light weight, easy to cut, fire and insulation is good, but its low strength, can not be arbitrarily loaded, more open slot openings, wet swelling and strength and insulation properties become lower. AAC block free-loading wall construction process using AAC block, shale brick, plain concrete mixed wall structure, block design by BIM, embedded in the AAC block wall of concrete blocks, masonry in the box office Shale brick wall to freely adapt to loading, slotting and wall deformation; the use of surface omentum and interface sealing process, to better solve the seepage and leakage prevention; the use of block walls and shale brick wall , The difference between the thickness of concrete beam column, the use of thermal bridge bite process, a better solution to the thermal bridge. This method systematically solves the problems of the quality of AAC block wall, uses limitation, enhances the integrality of AAC block wall, ease of loading slotted hole and water resistance, together with the characteristics of its factory production and processing , So that it can be more widely used in indoor and outdoor wall.
