This utility model discloses a sandwich-type color steel wall panel structure with integrated cable routing function, including an outer color steel plate, an inner color steel plate, a sandwich filling layer, and a
cable tray layer disposed within the sandwich filling layer. The outer and inner color
steel plates are arranged opposite each other and connected and fixed by a frame frame. The sandwich filling layer fills the space between the outer and inner color
steel plates. The
cable tray layer is disposed in the middle area inside the sandwich filling layer and is pre-embedded along the length or width of the wall panel. The
cable tray layer has one or more cable tray channels for concealed routing of power lines,
data lines, network cables, etc. This structure can complete concealed wiring simultaneously during wall panel installation, avoiding later grooving or surface conduit construction, improving construction efficiency and the aesthetic integrity of the wall, and is suitable for quick-
assembly building scenarios such as factories, mobile homes, and lightweight buildings.
