Accurate positioning device for corrugated steel web

The invention relates to the technical field of bridge construction, in particular to an accurate positioning device for a corrugated steel web, and solves the technical problem that a more universal accurate positioning mode with more universal adaptability is not given in the prior art. Specifically, the positioning mechanism is arranged on wing unfolding parts of a set of construction formworks and can move in the transverse direction of the construction formworks, the positioning mechanism is provided with a set of positioning ends, the positioning ends can move by a preset distance in the flange direction of the first end of the corrugated steel web, and when the positioning ends make contact with the flanges, the positioning ends move by a preset distance. One positioning point can be changed into two positioning points, and the two positioning points can be located on the center line of the flange. The technical scheme has the advantages that the arrangement mode of the corrugated steel webs adapting t
