Description

Technical Field

[0001] The invention relates to the field of steel structure webs, and in particular to an arc correction device for steel structure webs. Background Art

[0002] Box beams, H-shaped steels and other metal building materials all have web structures. During the processing of box beams and H-shaped steels, the webs are more likely to deform during the process of turning over the workpiece or welding. The deformed webs need to be corrected in time to avoid the deformation of the webs causing damage to the mechanical strength of steel building materials such as box beams and H-shaped steels, which cannot meet the actual use requirements. In the prior art, the correction operation for web deformation mainly includes the following process: first, place the channel bracket under the wing plate (or cover plate) of steel building materials such as box beams and H-shaped steels, and then place the block wedge between the channel bracket and the web of steel building materials such as box beams and H-shaped steels; then strike the block wedge to move it back and forth to squeeze the web of steel building materials such as box beams and H-shaped steels, so as to correct the protruding deformation. In addition, for the correction of the web concave deformation, it is necessary to weld a steel plate to pull out the local concave deformation of the web of steel structure materials such as box beams and H-shaped steels, and then spot weld and fix them at the weld bead of the web and wing plate (or cover plate). Finally, after assembly, the steel plate welded on the web needs to be removed, and the weld nodules left on the web of steel structure materials such as box beams and H-shaped steels need to be polished clean. It can be seen that the web deformation correction operation of steel structure materials such as box beams and H-shaped steels in the prior art is difficult, time-consuming, costly, labor-intensive, and inefficient. Therefore, it is urgent to provide a more reasonable and efficient technical solution to achieve the correction of the arc of the steel structure web.
