A box girder hogging moment stretch-draw notch quick-release formwork is of a rectangular integral structure defined by connecting four toothed plates, each toothed plate comprises a plate body, the lower portion of each plate body is in an evenly-distributed tooth shape, transverse plates are fixed to the inner side of the upper edge of each plate body, pin holes are formed in the two ends of each transverse plate, the pin holes in the adjacent transverse plates are matched in shape and position, and pins can penetrate into the pin holes to be fixed; splicing grooves matched with the adjacent transverse plates in shape are formed in the two sides of the edge of the plate body. The box girder hogging moment tensioning notch template can be used for construction of a conventional box girder hogging moment tensioning notch, changes the form of a traditional integral box girder hogging moment tensioning notch template, improves the traditional hogging moment tensioning notch construction process, solves the prob
