Embodiment Construction

[0027] A method for constructing a fireproof and anticorrosion wood grain coating on exposed parts of a steel structure, comprising the following steps:

[0028] Step 1: Derusting the exposed parts of the steel structure;

[0029] Step 2: Spray a layer of water-based steel structure anti-corrosion paint;

[0030] Step 3: Spray two layers of thick fire-resistant paint, with a thickness of 1-3mm; while spraying, level it with a manual iron plate; polish the water-based steel structure fire-resistant paint after it dries;

[0031] Step 4: Batch one piece of anti-cracking mortar, and then polish one piece;

[0032] Step 5: Batch a white smooth putty on the outer wall, and then polish it;

[0033] Step 6: Brush with the same color primer as the wood grain;

[0034] Step 7: Paint a layer of color aggregate for wood grain modeling on the surface of the primer with the same color as the wood grain. The color aggregate is 120 mesh quartz sand.

[0035] Step 8: Apply a water-based w...

Abstract

The invention discloses a construction method of a fireproof and antiseptic wood grain coating layer of an exposed part of a steel structure. The construction method comprises the following steps: (1) the exposed part of the steel structure is derusted; (2) water-based steel structure antiseptic paint is sprayed; (3) heavy fireproof paint is sprayed by a thickness to 1-3 mm; during spraying, a manual iron plate is used for leveling; and the polishing is performed after the water-based steel structure fireproof paint is dried thoroughly; (4) anti-crack mortar is coated for polishing; (5) exterior wall white glaze putty is coated for polishing; (6) primer with the same color with wood grains is brushed; (7) a color aggregate for shaping the wood grains is brushed on the surface of the primer with the same color with the wood grains; (8) water-based wood grain paint is brushed on the surface of the color aggregate; (9) the water-based wood grain paint is used for coloring the water-based wood grain paint coating layer; and (10) water-based fluorine carbon varnish is used for covering. The construction method enables a steel structure to achieve the same effect with logs and square timbers, so that the steel structure achieves the fireproof and antiseptic wood grain decoration two-in-one effect.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion and fire-proof treatment of steel structures, in particular to a construction method for fire-proof and anti-corrosion wood grain coatings on exposed parts of steel structures. Background technique [0002] Most of the exposed parts of steel structure buildings are treated with steel structure anti-corrosion coatings, and spray fire-resistant coatings after anti-corrosion treatment. At present, there are two construction methods of fire retardant coatings for steel structures, one is the spraying construction method of thick fire retardant coatings; the other is the spraying and brushing construction methods of thin fire retardant coatings. Both of these methods have problems of roughness and unsightly appearance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a construction method of a fireproof and anticorrosion wood grain c...
