Flange reinforced I-shaped steel

The utility model discloses flange reinforced I-shaped steel, and relates to the technical field of steel beams, the flange reinforced I-shaped steel comprises a web plate, one side of the web plate is fixedly connected with a lower flange, the other side of the web plate is fixedly connected with an upper flange, the middle section of the web plate is provided with a steel column, and the steel column penetrates through the web plate. Through cooperative arrangement of the steel columns, the supporting rods, the supporting plates and other structures, when the two sides of the upper flange are stressed, after pressure acts on the outer surface of the upper flange, the pressure can act on the supporting plates on the two sides of the upper flange, the upper flange is supported through the supporting plates, meanwhile, the pressure can be dispersed to the steel columns through the supporting plates, and therefore the supporting effect of the upper flange is improved. Pressure borne by the two sides of the uppe
