The invention discloses a separate type heat insulation plate anchor nail. The separate type heat insulation plate anchor nail mainly comprises a nail body, a tip top and a bolt. The nail body includes a nail rod, a sheet nail cap and a truncated cone-shaped tip bottom. The tip bottom is arranged on the upper end of the nail rod, and the bolt is a step-like bolt, wherein the diameter of the upper part of the bolt is small and the diameter of the lower part of the bolt is large. The tip top includes a conical tip boy and a cylindrical tip bump, the tip bottom and the tip body are respectively the upper part and lower part of a complete circular cone. The tip bump is arranged at the lower end of the tip body, a first blind hole is arranged in the axial direction of the upper portion of the nail body, and the first blind hole is in clearance fit with the tip bump. The tip bump further includes an upper tightening structure, a thread blind hole matched with an upper step bar is arranged in the axial direction of the lower portion of the tip bump, and a thread through hole matched with a lower step bar is arranged in the axial direction of the nail body. After batch production and processing in factory, the separate type heat insulation plate anchor nail is used for the construction in a building site, thus reducing a large number of high altitude hanging basket operations, and increasing the safety.
