Construction optimization method for autoclaved lightweight concrete wallboard standard layers based on 3D setting out

The invention discloses a construction optimization method for autoclaved lightweight concrete wallboard standard layers based on 3D setting out, and the technical problems that an existing autoclaved lightweight concrete wallboard standard layer is poor in construction quality and low in efficiency and economical efficiency are solved. The construction optimization method comprises the steps that 3D setting out is adopted on site, board construction drawing deepening is conducted according to a drawing obtained through setting out on site, the optimized drawing is sent to a manufacturer for cutting machining, construction of a first layer is completed according to the drawing, site wallboard installation personnel only need to snap lines at the positions of wallboards, strictly according to printed partition wall layout drawings, partition wall boards are directly installed according to the drawing numbers, acceptance check is conducted after installation of one layer is completed, construction of an upper l
