PROBLEM TO BE SOLVED: To provide a beam reinforcing structure capable of preventing a large construction cost to increase, by preventing welding of the whole peripheral part on the other surface side to a steel frame, by welding only the whole peripheral part on one surface side of a steel frame reinforcing member to the steel frame. SOLUTION: This beam reinforcing structure is constituted by using the steel frame 24, and forms a through-hole 24b in the steel frame 24. The beam reinforcing structure is characterized by having the steel frame reinforcing member 42 welding the whole peripheral part on the one surface side to a peripheral edge part of the through-hole 24b, and forming a cut surface 42b having a cross section of a straight line in a peripheral part corner part on the other surface side, and forming a shaft hole 42b having a diameter smaller than the through-hole 24b.
