Adjustable inhaul cable reinforcing device for thin-wall round concrete formwork reinforcing

The utility model provides an adjustable inhaul cable reinforcing device for thin-wall round concrete formwork reinforcing. An inhaul cable plate anchoring steel ring of the reinforcing device is connected with an edge plate of an inhaul cable plate steel plate in a welded mode, an anchoring steel pull ring is fixed to the inhaul cable plate anchoring steel ring through a bolt, the anchoring steel pull ring is connected with one end of a reverse thread fastening lock through a steel wire rope, and the other end of the reverse thread fastening lock is connected with formwork split bolts; by means of the formwork split bolts, an inner side arc main reinforcing rib and an outer side arc main reinforcing rib are clamped, the inner side of the inner side arc main reinforcing rib and the inner side of the outer side arc main reinforcing rib are respectively provided with a formwork secondary reinforcing rib, and the inner sides of the formwork secondary reinforcing ribs are provided with wood formworks. The device has the advantages that the roundness of the formworks can be adjusted accurately; adjustable inhaul cable plates can be evenly distributed in the height direction at intervals to be suitable for thin-wall round concrete structures of any height; the overall rigidity of the formworks can be improved; it is guaranteed that the surfaces of concrete components are flat and smooth; the adjustable inhaul cable reinforcing device is suitable for thin-wall round concrete structures with different diameters.
