Technical Field

[0001] This utility model belongs to the field of steel beam welding technology, and in particular relates to a steel beam welding support and protection device. Background Technology

[0002] Steel beams are beams made of steel. They are used in various applications, including crane beams and work platform beams in factories, floor beams in multi-story buildings, and purlins in roof structures. Steel beams are typically fabricated from structural steel sections, requiring welding and other processes to achieve specific lengths.

[0003] For the steel beam welding process, a support structure is used to support the steel beam to form a straight structure and align the connection between the two for welding. To maintain the stability of the welding process, a limiting device is also used to clamp the steel beam. During the welding process, sparks and weld spatter are likely to be generated. Because this type of support structure needs to limit the assembly of the steel beam, it is not easy to install a protective partition structure. Utility Model Content

[0032] The protective unit 200 is connected to two sets of support units 100 by plugging in. It includes a main rod 210, a lower extension plate 230 and a protective plate 220. There are two sets of each of the main rod 210, the lower extension plate 230 and the protective plate 220. The lower extension plate 230 is connected to one end of the main rod 210 and placed parallel to the steel beam 300. The protective plate 220 is connected between the two sets of main rods 210. The main rod 210 is provided with several sets of plug-in seats 260. The side wall of the U-shaped frame 130 is provided with slots 131 that are adapted to the plug-in seats 260.

[0033] The protective unit 200 is connected to different U-shaped frames 130 via a plug-in connector 260. The protective plate 220 spans across the steel beam 300.
