Description

Technical Field

[0001] The utility model belongs to the technical field of load-bearing beam structure design, and in particular relates to a high-strength I-beam structure suitable for various high-quality load-bearing beams. Background Art

[0002] Most of the structural beams of traditional design components are made of I-beam profiles, and the components are mainly supported by the longitudinal beams when the horizontal and vertical beams are overlapped. The horizontal beams are segmented. In this structure, the horizontal and longitudinal beams are unevenly stressed, and the structural strength is only guaranteed by the welded welds. This structural design is only suitable for ordinary and light-weight component structures and cannot meet the design requirements of large or high-strength components. In order to improve the stability of special vehicle components, the high-strength I-beam structure should be overlapped by mortise and tenon structure, and the overlap of the horizontal and longitudinal beams should be in the form of plug-in connection, so that the horizontal and longitudinal beams are evenly stressed, ensuring the high bearing strength of the component and reducing the deformation caused by the longitudinal stress concentration of the component.
