Special-shaped aluminum alloy grating curtain wall construction method

The invention relates to a construction method of a special-shaped aluminum alloy grating curtain wall, which is characterized in that through deepening design of an outer wall aluminum alloy grating curtain wall, the construction method comprises the following steps of: measuring and distributing points of a grating curtain wall keel and a facing system which meet the building facade modeling, measuring and distributing points of an outer wall profile, arranging a rear embedded part, positioning a grating upright post, controlling the distance between grating plates, connecting the upright post and a grating, splicing the grating and the like. In the construction process, the installation mode of orderly splicing of the aluminum alloy grating is researched, and the grating plates are installed in an inserted mode, so that the grating is easier and more convenient to install and detach. Meanwhile, by optimizing the splicing seams of the splicing positions, the exterior facing effect and integrity of the grati
