Light self-insulation composite wallboard and manufacturing method thereof

The invention belongs to the technical field of architectural engineering and particularly relates to a light self-insulation composite wallboard for architectural engineering such as frames, framed bents and shear walls and a manufacturing method thereof. The light self-insulation composite wallboard comprises an insulation board, ceramsite concrete sheets are arranged on both sides of the insulation board, and the ceramsite concrete sheets on the two sides are fixedly connected with each other through a shear-resisting and compression-resisting connecting part which penetrates through the insulation board. Steel wire meshes are arranged in the ceramsite concrete sheets, the left end and the upper end of the insulation board are concave inside the ceramsite concrete sheets on the two sides so as to form a groove, and the right end and the lower end of the insulation board protrude out of the ceramsite concrete sheets on the two sides so as to form a rib. A wall body is carried to a construction site after be
