The invention discloses a steel structure joint corrosion prevention method and a mold, and belongs to the technical field of buildings. A method for polishing and derusting in advance is used for preventing polishing and derusting after installation of a steel structure joint connecting plate, so that the problem of incapability of thoroughly removing dark joint rust due to dense bolts in joint positions and uneven derusting surfaces is solved, the pre-polishing efficiency is high, and the operation is easy; rust foam is prevented from flying all around during polishing and derusting after installation of steel structure joints; bolt holes in the connecting plate are blocked by using a prefabricated mold; the operation can be directly performed; the construction process is simple; and the cost is low. The method comprises the following steps before installation of the steel structure joint connecting plate: polishing and derusting the steel structure joint connecting plate; blocking the bolt holes of the ste
