Thin fireproof coating for steel structure is sprayed on the surface of steel structure, aiming at the fireproof and heat insulation protection of steel components, preventing the steel structure from rapidly heating up and distorting and collapsing in the fire. The following 3 points should be emphasized in the construction process of steel structure thin fireproof coating:
Thin fireproof coating for steel structure needs to be checked in the field
When the indoor steel structure thin fireproof coating enters the field, it should check whether the steel structure thin fireproof coating meets the design requirements, test the product specification of steel structure thin fireproof coating, product qualification certificate, type inspection report and qualification of the corresponding supplier; after the thin fireproof coating enters the field, it should be witnessed to take samples, and the sampled samples should be sent to the quality inspection organization for inspection.
Construction Management of Thin Fireproof Coating for Steel Structure
Before the construction of thin fireproof coating for steel structure, the selection of antirust paint and fireproof coating should be checked to see if it is reasonable; during the construction of thin fireproof coating for steel structure, the damaged antirust paint should be repaired first, and attention should also be paid to whether the environment such as temperature, humidity and wind speed can satisfy the construction requirements.
Acceptance of steel structure thin fireproof coating
After the construction of thin fireproof coating for steel structure is completed, the spraying of indoor fireproof coating should be accepted according to the specification, and the coating appearance of thin fireproof coating, coating thickness of thin fireproof coating for steel structure and the number of cracks in the coating should also reach the qualified standard. Acceptance of the thickness of thin fireproof coating for steel structure is carried out by thickness measuring instrument, average value is calculated and compared with the specification standard until the thickness of thin fireproof coating spraying for steel structure is judged to be qualified.
