[0031] Please refer to Figures 1-4 A robust connection and reinforcement structure, comprising:
[0032] Two I-beams 1 are connected by bevels 2 on the upper and lower flanges of the connecting ends. These bevels 2 are designed to facilitate welding and form a V-shaped notch after butt welding, which allows the two steel beams to be connected more firmly through full penetration welding. The same backing plate 3 is attached to the inner wall of the two bevels 2 after butt welding, which further enhances the tightness of the contact. The notch of the two bevels 2 after butt welding is filled with the same welding core 4. The two I-beams 1 are connected together by full penetration welding. The design of the backing plate 3 and the welding core 4 ensures the uniformity and strength of the welding, while avoiding the problem of bolt protrusion on traditional connecting plates.
