Description

Technical Field

[0001] The utility model relates to the technical field of steel structure construction, in particular to a steel structure fire retardant coating construction device. Background Art

[0002] As the main form of modern architecture, steel structure has the advantages of light weight, high strength, good earthquake resistance, short construction period, high degree of building industrialization, and large space utilization at room temperature. It can save investment and is widely used by investors. However, the poor fire resistance of steel structure buildings is also very significant, because although steel is a non-combustible material, it is a good conductor of heat and can easily conduct heat. When the temperature exceeds 300 degrees, the yield point and ultimate strength of steel decrease significantly, and the strength is almost zero when it reaches 600 degrees. In the case of fire, the temperature of an unprotected steel structure will rise to more than 540 degrees in just 15 minutes, causing the components themselves to twist and deform, leading to the collapse and destruction of the building. The deformed steel structure cannot be repaired and used, so fire protection measures must be taken for the steel structure, such as fire retardant coatings.

[0003] At present, in the construction process of buildings or other fields, the steel structures used are mostly steel pipes, and the location for spraying fire retardant coatings is usually the outer surface of the steel pipes. In order to spray the outer surface of the steel pipe evenly, most of the methods adopted are to fix the steel pipe vertically on a rotating platform for rotary spraying. However, due to the fixed spraying of the steel pipe, the steel pipe needs to be removed after spraying, and then reinstalled for spraying again, which reduces the spraying efficiency of the steel pipe. For this reason, we propose a steel structure fire retardant coating construction device. Utility Model Content
