Beam column construction technology of large-span steel structure building

The invention discloses a beam-column construction process of a large-span steel structure building, and relates to the technical field of steel structures, according to the beam-column construction process of the large-span steel structure building, after a steel column is installed, a supporting plate is fixedly installed on one side of the steel column through bolts, and then after a large-span steel beam is welded, the supporting plate is fixedly installed on the other side of the steel column; the positioning plates are fixedly installed at the proper positions of the large-span steel beams through bolts, then the large-span steel beams are hoisted to be located above the horizontal ends of the positioning plates, the positioning blocks are located over the positioning holes, the large-span steel beams are hoisted and put down, the positioning blocks correspondingly enter the positioning holes, and then rapid positioning and installation of the large-span steel beams can be completed.
