The invention discloses a steel structure anticorrosion construction method, and relates to the technical field of steel structure protection; the coating process aims to solve the problems of complex coating process and insufficient protection performance; the method specifically comprises the following steps: pretreatment before construction: checking whether the materials and the used equipment are complete and normally operate, and then clamping and fixing the unfixed steel member; surface treatment: decontaminating and purifying the surface of the steel structure to be coated; coating treatment and brushing: preparing a steel structure coating and sequentially overlapping and coating according to requirements; quality inspection and acceptance: carrying out quality inspection on the dried steel structure coating according to inspection requirements; the sequential overlapping and coating sequence in the coating treatment and coating is as follows: the coating comprises a primer, a first layer of anticorrosive coating, an impact-resistant reinforced layer, a second layer of anticorrosive coating and a finish, wherein the coating brushing times in each sequence are more than or equal to 2 times. The invention has simple process, can obviously reduce and avoid the later-stage corrosion prevention maintenance cost of the steel structure, has high-efficiency protection effect on the matrix and achieves the aim of long-acting corrosion prevention. |
