Corrugated steel web positioning device and positioning method thereof

The invention discloses a corrugated steel web positioning device and a positioning method thereof, and belongs to the technical field of corrugated steel web installation, through movement of a moving seat, two pairs of clamping structures are matched with the length of a corrugated steel web, when two rotating threaded columns are parallel, an abutting disc can stretch into the concave face position of the clamping face of the corrugated steel web, and a certain gap exists between the abutting disc and the clamping face of the corrugated steel web; the disc seat rotates to drive the suspended corrugated steel web to perform angle deflection until the required deflection angle is reached, the corrugated steel web is lowered through a crane, and then the corrugated steel web can be stably and safely moved to the mounting position of a concrete bottom plate, the mounting device can perform angle deflection on the steel web with the corrugated structure, and the mounting efficiency is improved. And in the hoist
