The bridge deck steel lattice beam consists of a main longitudinal beam, a secondary longitudinal beam, a small longitudinal beam, a main cross beam, a secondary cross beam and an end cross beam; the main cross beam is arranged corresponding to the position of the suspender along the bridge direction, the secondary cross beam is arranged between the main cross beams, and the main cross beam and the secondary cross beam are both generally provided with I-shaped cross sections. The steel lattice beam is not provided with an independent steel longitudinal beam, but is blanked into a cross-shaped cantilever through a wing plate of the steel cross beam to form the steel longitudinal beam, and all butt joints and T-shaped joints of the lattice beam are welded completely by fusion penetration. During welding, the molten steel and the base metal in the near seam area expand by heat to generate plastic deformation. During solidification, the steel materials of the welding seam and the near seam area shrink to generate longitudinal and transverse internal stress, so that the welding seam shrinks longitudinally and transversely, and the weldment deforms. In order to ensure that the bolt holes of the connecting nodes of the longitudinal beam web plates can be accurately aligned and assembled and installed in the hoisting stage, welding deformation needs to be corrected in the lattice beam machining process.
The existing welding deformation correcting device for the T-shaped section and the I-shaped section has certain requirements on the corrected minimum section height, and the larger section cannot be corrected by adopting a professional correcting machine; the straightening machine cannot limit the component, so that the accuracy of deformation correction is influenced; the professional straightening machine is generally practical in a steel structure processing factory, is not flexible and convenient to use in a construction site, and is poor in applicability.
