Flow-guide-type foamed structure and prefab composite wall panel, and preparation method thereof

Disclosed are a flow-guide-type foamed structure and a prefab composite wall panel, and a preparation method thereof, wherein the composite wall panel is formed of foamed structures (2), prefabs (3), a flow-guide frame (4) and a face panel (1). The flow-guide frame (4) is a plate-like structure, a plate face of which is arranged perpendicular to the panel (1). The entire composite wall panel is divided into multiple unit blocks of foamed structure (2) or prefab (3) by means of the flow-guide frame (4). The flow-guide frame (4) is located between the foamed structures (2) and the prefabs (3) and/or along an outer edge of the entire composite wall panel. There are two panels (1), and the prefabs (3) have a maximum value of 75% of the total area of the cross section. The prefabs (3) are pieces of sound-proofing and heat-insulating plate-like material containing air, the thickness thereof is 50 mm-100 mm and the unit weight thereof is 30 kg/m
