Steel structure and welding process thereof
The invention relates to a steel structure. The steel structure comprises a web, four flange plates welded to the web, rib plates, two side plates, a plurality of welding columns and lifting lugs. Thetwo side ends of each rib plate are welded to the web and the corresponding flange plate correspondingly, the two side plates are welded to the flange plates, the welding columns are welded to the web, and the lifting lugs are connected with the side plates through bolts. The four flange plates are symmetrically welded to the two sides of the web. The rib plates are used for connecting the web with the flange plates, and the welding columns are symmetrically distributed at the two ends of the web. At least two connecting points are arranged between the lifting lugs and the side plates, and holes are formed in the lifting lugs and used for hoisting hooks. The flange plates and the web are welded through electric resistance welding. The rib plates, the web and the flange plates are welded through gas shielded arc welding. The side plates and the web are welded through tubular welding wire arc welding, and the welding columns and the web are brazed. According to the steel structure and awelding process thereof, the problems of repeated welding and lifting lug cutting during hoisting of the steel structure are solved, damage to the steel structure before and after hoisting of the steel structure is reduced, and the problem that the strength of a welding point of a traditional steel structure is insufficient is further solved.
本发明涉及一种钢结构，包括腹板、与腹板焊接的四个翼缘板、两侧端分别焊接在腹板与翼缘板上的肋板、焊接在翼缘板上的两个侧板、焊接在腹板上的多个焊柱和与侧板螺栓连接的吊耳；四个翼缘板对称焊接在腹板的两侧；肋板用于连接腹板与翼缘板；多个焊柱对称分布在腹板的两端；吊耳与侧板的连接点至少为两个，吊耳上设有孔，用于吊装钩挂。翼缘板与腹板的焊接采用电阻焊；肋板与腹板、翼缘板的焊接方式采用气体保护电弧焊；侧板与腹板的焊接方式采用管状焊丝电弧焊；焊柱与腹板的焊接采用钎焊。本发明解决了钢结构吊装时反复焊接和切割吊耳的问题，降低了钢结构吊装前后对钢结构的损伤，还解决了传统的钢结构的焊接点强度不够的问题。
