The invention discloses a waterproof structure of a screw hole of a facade shear wall. The waterproof structure comprises a conical sleeve pipe, and a positioning buried piece, wherein the conical sleeve pipe is arranged at the middle section of the wall penetrating screw rod in a sleeving mode, a conical hole with the shape consistent with the shape of the conical sleeve pipe is formed in the shear wall, the conical hole penetrates through the upstream face and the downstream face of the shear wall, a first hole is formed in the upstream face, a second hole is formed in the downstream face, and the first hole is lower than the second hole; and the positioning buried piece is buried on the side of the upstream face of the shear wall, a positioning rod is connected to the positioning buriedpiece, a positioning hole for allowing the positioning rod to be inserted into is formed in an outer side template, located on one side of the upstream face, of the shear wall, and the distance between the positioning hole and the screw hole for allowing the wall penetrating screw rod to penetrate through and formed in the outer side template is equal to the distance between the corresponding positioning buried piece and the first hole. The waterproof structure uses the conical sleeve pipe to make the outer wall screw hole be always lower than the inner wall screw hole, and rainwater cannot penetrate into a building through the screw hole accordingly.
