Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an AAC autoclaved aerated concrete strip board vertical assembly unit structure to realize vertical application assembly of large boards. Background Art

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

[0003] Therefore, the following problems exist: 1. Not only is the cost high, but auxiliary components are also needed to fix the steel frame to the main structure of the building, which results in low assembly efficiency. Moreover, the auxiliary components are exposed to the outside, which not only occupies indoor space, but also requires additional decoration costs to cover up these defects later; 2. The combined structure (large slab) of traditional steel frame and AAC autoclaved aerated concrete slab is mostly transported by vertical loading on a bracket, which not only limits the height but also increases the transportation cost.
