The invention provides an aluminum sectional material framework for old wall heat insulation structure modification. The aluminum sectional material framework comprises a main body, wherein the cross section of the main body is in a step shape; one side with the smaller step surface is tightly attached to a wall body; a plurality of embedded grooves are formed in the side walls of the two sides in the length direction of the main body; the embedded grooves are distributed in the side walls of the two sides of the main body in the length direction; the two ends of the main body are provided with conical countersunk holes; the bottom of each countersunk hole is provided with a fixing hole; the main body fixed on the wall body through the fixing holes and expansion bolts; and the surface of the main body is provided with concave-convex corrugated bonding positions. The aluminum sectional material framework has the advantages that high durability, high constructability, good anti-sagging performance and strong bonding force are realized; during the construction, the labor and the materials can be saved; resources are saved; the flying dust is avoided; meanwhile, the service life of a building can be greatly prolonged.
