Steel structure assembling should give priority to the construction template, and notify the engineering supervision, cell owners, design and other departments for acceptance. In the construction, it is necessary to pay attention to whether the steel structure connection is reliable, whether the welding is in accordance with the regulations, whether the steel structure is fireproof, anticorrosion and antirust treatment, whether the lightning protection is in accordance with the regulations, and whether the safety construction program and safety of the steel structure are in accordance with the regulations.
It has the function of fireproof and flame retardant. The steel structure fireproof coating is applied in the steel, which can improve the steel's resistance to high-temperature flames, and its fire-resistant limit can reach two hours, which in turn enhances the building's fireproofing and heat-insulating properties, and makes it stronger; while the unused steel can only withstand the flame impact for about 15 minutes.
The construction steps of fireproof coatings are usually as follows: 1. Surface preparation: First of all, clean and treat the surface to be coated to ensure that the surface is free of oil, dust or other pollutants. If there is rust on the surface, it also needs to be removed.2. Primer coating: After the surface preparation is completed, apply a special fireproof primer. The selection of primer should meet the required fire protection standards and be constructed in accordance with the manufacturer's recommendations.
