[0002] Currently, steel structures are one of the most common building structures. Steel's characteristics include high strength, light weight, good overall rigidity, and strong deformation capacity, making it particularly suitable for constructing large-span, ultra-high, and ultra-heavy structures. In actual production, position lines, allowance lines, inspection lines, and bevel lines are often marked on products for assembly positioning and inspection.
[0003] At present, when marking steel structures, traditional auxiliary marking rulers are still used. It is inconvenient to perform operations such as oblique lines, arcs and circles during the marking process, and an external ruler is required for assistance. At the same time, both hands are required to operate when marking. At this time, the reference ruler loses pressure and is easily displaced, which causes inaccurate marking. At the same time, since most steel structures are H-shaped structures, the existing marking device can only mark on a flat surface. Therefore, the present application proposes a device for cutting and marking steel structures. Utility Model Content
