Description

Technical Field

[0001] The invention belongs to the technical field of steel structure processing, and in particular relates to a multi-section assembly method and structure of a steel structure special-shaped base and an I-beam. Background Art

[0002] As an important system of prefabricated steel structure housing, special-shaped steel structure not only improves the structural bearing capacity and rigidity, but also meets the requirements of applicability and aesthetics of the building. Steel structure engineering is the earliest to realize prefabricated construction. The so-called prefabricated steel structure is prefabricated first and then assembled. That is, the drawings are first refined according to the nodes, and beams, columns and connectors are prefabricated separately, and anti-rust paint is applied.

[0003] Steel structure assembly refers to the assembly and fitting of steel structures. At present, when assembling steel structures, some larger processing plants will use some more advanced automated equipment to position the steel plates, and then weld the joints of the steel plates to fix the steel plates firmly. However, due to the high cost of automated equipment, some small steel processing companies cannot afford it, resulting in many companies still manually positioning the steel plates during the assembly of steel structure boxes. Manual assembly of steel plates is labor-intensive, with low work efficiency, and the positioning accuracy of the steel plates cannot be guaranteed.

[0004] When assembling special-shaped steel structures, since special-shaped components are difficult to match with I-beams, more screws and welding are needed to achieve them, and it is difficult to ensure the stability and rigidity of the structure. Additional fixation is often required. It is necessary to design the special-shaped steel structure so that no additional problems will occur when it is assembled with the I-beam. Summary of the invention

[0005] The present invention aims to overcome the deficiencies in the above-mentioned prior art and aims to provide a method and structure for assembling a special-shaped base of a steel structure and an I-beam in a multi-section manner. The special-shaped base and the I-beam are assembled by connecting the special-shaped steel structure and the I-beam through a combination of screw inlay connection and welding. On the basis of the conventional method, the special-shaped base and the I-beam are secondary fixed by using a T-shaped connecting rod, which greatly improves the connection firmness of the special-shaped base and the I-beam, ensures the stability of the special-shaped base and the I-beam, and greatly improves the efficiency of the assembly work.
