Abstract
A correction device for welding deformation of a steel box girder panel comprises portal upright columns on two sides, portal cross beams, a movable trolley, jacks and trays; the two side portal upright columns are fixedly connected to two sides of the deformation position of the steel box girder panel, the portal cross beams are installed between the two side portal upright columns, the moving trolley penetrates into the portal cross beams, the tray is arranged at the bottom of the moving trolley, the jack is arranged in the tray, and the moving trolley and the tray are connected through a guide chain. The movable trolley slides by tightening the guide chain, so that the jack moves to the deformed steel box girder panel; the jack is shaken to jack the steel box girder panel and the portal beam tightly until the deformation is corrected; and moving the jack to other deformation positions by tightening the guide chain to continuously correct the steel box girder panel until all corrections are finished. The method can be suitable for correcting the deformation generated when the steel structure panel with larger thickness is welded on any construction site.
