Curtain wall steel structure mounting method

Abstract

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.

Description

technical field [0001] The invention relates to the field of building exterior wall decoration, in particular to a curtain wall steel structure installation method. Background technique [0002] Curtain wall is an external wall construction method that uses various strong, light and beautiful building materials to replace the traditional masonry or window-wall combination. It is surrounded by the periphery of the main structure to make the whole building beautiful, functional and safe. Wall construction method. [0003] Due to the beauty of the curtain wall, the curtain wall is widely used in high-end office buildings and large shopping malls. The curtain wall is fixed by the steel structure fixed on the building structure. The steel structure needs to be connected with the building structure with a buried plate. The buried plate is a thermal insulation with a certain thickness. Dipped galvanized steel, often fixed to building structures by chemical anchors. [0004] Becau...

Problems solved by technology

[0005] The steel used in the curtain wall is often treated with hot-dip galvanizing for anti-rust treatment. Before hot-dip galvanizing, the rust on the outer surface of the steel needs to be removed, but during the period after the steel is completely removed and then hot-dip galvanized, the steel Without any anti-oxidation treatment, there is still a certain amount of rust on the outer surface of the steel and oxides are formed on the outer surface of the steel. After hot-dip galvanizing, the oxygen on the outer surface of the steel can easily cause the galvanized layer to grow. Rust, thereby reducing the anti-rust effect of the zinc layer, thereby reducing the service life
