[0002] During the construction of steel structures, welding is usually used to fix the heavy steel beam and the C-shaped steel beam. Since a welding gun needs to be used in conjunction with the welding, and the welding accuracy is difficult to control when the heavy steel beam and the C-shaped steel beam are welded together, the C-shaped steel beam and the heavy steel beam are tilted during assembly, thereby reducing the stability of the assembly of the C-shaped steel beam and the heavy steel beam. Therefore, in order to facilitate the fixation of the heavy steel beam and the C-shaped steel beam, an L-shaped connecting plate and a clamping plate are currently used to fix the heavy steel beam and the C-shaped steel beam. When the C-shaped steel beam is deformed under weight, the connecting plate will also deform accordingly, and the effect of fixing and supporting the heavy steel beam and the C-shaped steel beam needs to be further improved;

[0003] In this regard, the utility model provides a connection reinforcement structure for the ends of a heavy steel beam and a C-shaped steel beam, which is fixed to the heavy steel beam and the C-shaped steel beam through a side U-shaped connector. Utility Model Content
