This utility model belongs to the field of composite panel exterior wall technology, and particularly relates to an aluminum-plastic composite panel exterior wall structure system, including a composite aluminum panel, and further comprising: a galvanized steel pipe movably installed on one side of the composite aluminum panel, a galvanized steel plate being installed through the interior of the galvanized steel pipe, fireproof cotton being fixedly installed inside the galvanized steel plate, and gunpowder nails movably installed on one side of the galvanized steel plate. Multiple composite aluminum panels can be spliced ​​together for easy assembly and support of the exterior wall. The galvanized steel plate is then fixed to one side of the composite aluminum panel to enhance its support stability. The galvanized steel plate is fixed by gunpowder nails, and fireproof cotton is placed inside the galvanized steel plate to provide fire protection and enhance the fire resistance of the composite aluminum panel. The fireproof cotton is made of inorganic fiber cotton, which enhances fire resistance. When used in conjunction with the composite aluminum panel, the inorganic fiber cotton effectively enhances the fireproofing effect.
