The invention discloses a
curtain wall steel structure mounting method. The method includes steps: S1, subjecting a steel material to
rust removal and application of high-temperature
combustion paint; S2, subjecting the steel material to hot-dip
galvanization; S3, determining a steel structure mounting position on the outer surface of a building structure; S4, mounting a buried plate, removing an anti-
rust coating on the buried plate, and
coating with the high-temperature
combustion paint; S5, drawing steel material fixing points on the buried plate; S6, drawing a contact profile on the buried plate after the steel material and the buried plate are fixed; S7, hoisting the steel material to the buried plate; S8, making
welding portions of the steel material to be welded to the buried plate; S9, removing a hot-dip galvanized
coating at the steel material
welding portions, and applying the high-temperature
combustion paint; S10, using hoisting equipment for hoisting the steel material to the buried plate; S11, heating the high-temperature combustion paint on the buried plate and the steel material; S12,
welding the buried plate and the steel material; S13, adopting anti-
rust paint for anti-rust treatment. By adoption of the high-temperature combustion paint for anti-rust treatment of the buried plate and the steel material exposed in a mounting process, steel structure rusting probability is decreased.
