PROBLEM TO BE SOLVED: To provide a beam through hole reinforcing structure in which fittings can exert sufficient reinforcing effects even if the fittings are bolt-connected to a beam. SOLUTION: According to the beam through hole reinforcing structure 1, the beam through hole reinforcing fittings 2, 2a cooperatively pinch a beam through hole 17, and the beam through hole reinforcing fittings 2, 2a are fastened to each other by a high-strength bolt inserted into a bolt insertion hole. Further a tapered portion 5 of the beam through hole reinforcing fitting 2 and a rim 21 of the beam through hole 17 make contact with each other at a predetermined angle over the entire circumference, and a tapered portion 5a of the beam through hole reinforcing fitting 2a and the rim 21 of the beam through hole 17 also make contact with each other at the predetermined angle over the entire circumference. Then by fastening the beam through hole reinforcing fittings 2, 2a together by the high-strength bolt, the beam through hole reinforcing fittings 2, 2a are stuck to the beam 11 without a gap therebetween.
