Technical Field

[0001] This invention belongs to the field of steel structure technology, specifically relating to a method and device for actively controlling the verticality of steel structure welding. Background Technology

[0002] Steel structure buildings are widespread. When there are steel structures that need to be welded during design or construction, especially vertical steel structures, the verticality of the steel structure is difficult to guarantee during the welding process with the assistance of lifting machinery due to the long length and heavy weight of the upper and lower steel structures. This has a certain impact on its longitudinal load-bearing capacity and reduces the overall safety and stability of the steel structure.

[0003] In related technologies, the verticality of steel structure welding is checked by using the wire rope laying method or the hydraulic plumb line method. This check is carried out entirely manually, which results in large errors and high labor intensity. Summary of the Invention

[0025] (1) Control structure 1 moves detection structure 2 to the height of weld 3 and adjusts the distance between detection structure 2 and weld 3;

[0026] (2) Based on the wind force magnitude at the height of weld 3 collected by the wind force sensing unit 21 of the detection structure 2, when the wind force value is within the preset deviation range, the relative position between the detection structure 2 and weld 3 is further adjusted.

The gravity plate can be a magnetic plate or a gravity plate detachably connected to the bottom of the detection structure 2. Within a certain wind force range, the detection structure 2 of a certain weight is not affected by the wind direction and can accurately detect the verticality of the weld 3.
