Steel derusting machine for constructional engineering

The utility model relates to the technical field of metal material derusting equipment, in particular to a steel derusting machine for constructional engineering, which comprises a fixed support and a movable support, a plurality of derusting structures are relatively and fixedly mounted at the upper end of the fixed support, and a plurality of derusting structures are relatively and fixedly mounted on the bottom side of the movable support. And the derusting structure is provided with different brackets so as to adapt to different working requirements. According to the utility model, by replacing different support structures, the whole device is endowed with different working modes so as to meet different working requirements, is convenient to use and adopts a spliced structure, so that the actual size of the rust removal structure is not fixed any more, the rust removal structure can be adjusted according to the actual requirements, and the outer rotor is driven by the inner stator during the polishing work
