Embodiment Construction
[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0038] refer to figure 1 , is a steel structure disclosed in the embodiment of the present invention, including a web 11, four flange plates 12, a plurality of ribs 13, two side plates 14, a plurality of welding posts 15 and the Four lugs 16.
[0039] refer to figure 1 and figure 2 , The web 11 includes a main web 111 and four auxiliary webs 112, the main web 111 is made of a whole steel plate without welding, and both the main web 111 and the auxiliary web 112 are made of 45 steel. The four flange plates 12 are distributed in pairs on both sides of the two largest end surfaces of the main web 111, the flange plates 12 are welded on the main web 111, and the four flange plates 12 are located on the main web 111. The plane is symmetrical, the flange plate 12 is perpendicular to the main web 111, and the flange plate 12 is welded along the length direction...

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.
Description
technical field [0001] The invention relates to the field of steel structure production and manufacturing, in particular to a steel structure and its welding process. Background technique [0002] Steel structure is a structure composed of steel materials. In the process of engineering construction, it is often necessary to make various steel structures. In the process of steel structure production, it is often necessary to weld lifting lugs on the steel structure, hoisting After completion, the lugs need to be cut off again, but this process is easy to cause damage to the surface of the steel structure, which is not conducive to the use of the steel structure, and traditional steel structure welding usually uses manual welding or fusion welding, resulting in steel The strength of the welding point of the structure is not enough in some specific occasions. Contents of the invention [0003] In view of the deficiencies in the prior art, the first object of the present inve...
