[0002] At present, most traditional AAC autoclaved aerated concrete strips are installed in single sheets, and processes such as drilling bolt holes and cutting boards need to be carried out on the construction site, which not only has low construction efficiency but also pollutes the environment. Therefore, there are many AAC large-board assembly technologies, but most of them are factory assembly solutions and do not involve on-site installation of structural nodes.
