PROBLEM TO BE SOLVED: To provide a beam through hole reinforcing structure in which fittings exert sufficient reinforcing effect even if the fittings are bolt-connected to a beam. SOLUTION: According to the beam through hole reinforcing structure 1, beam through hole reinforcing fittings 2, 31 cooperatively pinch a beam through hole 17, and they are fastened to each other by fastening a bolt inserted into a bolt insertion hole. A projection 9 of the beam through hole reinforcing fitting 2 is penetrated into the beam through hole 17 and fitted into a through hole 17 formed in the beam through hole reinforcing fitting 31. Thus the beam through hole reinforcing fittings 2, 31 are combined together in one body to inhibit out-of-plane deformation of the other member. Further when a stress is applied to the beam 11, the beam through hole reinforcing fittings 2, 31 cooperatively transfer the stress, and therefore shear strength thereof is increased. As a result, the stress applied to the beam 11 can be efficiently transferred to the beam through hole reinforcing structure 1. COPYRIGHT: (C)2007,JPO&INPIT
