Honeycomb aluminum plate system

The invention discloses a honeycomb aluminum plate system. The honeycomb aluminum plate system comprises an inner layer structure and an outer layer structure. The inner layer structure comprises a lower layer keel and an upper layer keel, an interlayer is formed between the lower layer keel and the upper layer keel, and a heat preservation and sound absorption assembly is arranged in the interlayer; the outer layer structure comprises an outer layer keel, a drainage frame and a honeycomb aluminum plate, the drainage frame is provided with a drainage groove, the outer layer keel is connected to the upper layer keel, the drainage frame is connected to the outer layer keel, and the honeycomb aluminum plate is connected to the drainage frame. The heat preservation and sound absorption assembly of the honeycomb aluminum plate system is continuously arranged between the double layer keels and is not broken, the cold bridge phenomenon is completely eradicated, and the heat preservation effect is good; a multi-layer
