Abstract
The invention discloses a fair-faced concrete imitating coating structure suitable for the surface of a steel structure and a process method. A back coating glue layer is fixedly bonded on the steel structure, an interface agent layer special for an outer wall is fixedly bonded on the back coating glue layer, a grid layer special for the outer wall is arranged on the interface agent layer special for the outer wall, and a first anti-crack mortar layer is coated and scraped on the interface agent layer special for the outer wall; a second anti-crack mortar layer is coated and scraped on the outer wall special grid layer, an outer wall external corner strip is arranged at the right-angle position of the second anti-crack mortar layer, an outer wall flexible putty layer is fixedly connected to the second anti-crack mortar layer and the outer wall external corner strip, a second outer wall flexible putty layer is fixedly connected to the first outer wall flexible putty layer, and an imitated clear water coating primer layer is fixedly connected to the second outer wall flexible putty layer; a pattern layer is arranged on the imitation clear water coating primer layer; and a fluorocarbon finish paint layer is solidified on the pattern layer. The back coating glue layer can increase the bonding force between the surface of the steel structure and a coating material, the steel structure and the coating material are tightly bonded together and do not fall off after being coated, the color of the steel structure is close to the color of a peripheral concrete structure, and the maintenance and rework cost is saved.
Description
technical field [0001] The invention relates to the technical field of steel structure coating, in particular to an imitation fair-faced concrete coating structure and method suitable for steel structure surfaces. Background technique [0002] When the ordinary landscape steel bridge is painted, it will be painted with paint close to the color of the surrounding concrete structure to ensure that there will be no large color difference between the appearance of the steel bridge and the appearance of the surrounding concrete structure. However, due to the coating method and other reasons of the commonly used paint, there will still be a certain deviation between the appearance of the steel bridge and the surrounding concrete structure, resulting in an abrupt effect. Contents of the invention [0003] The invention provides an imitation fair-faced concrete coating structure and method suitable for the surface of steel structures to solve the existing paint coating structure u...
