<P>PROBLEM TO BE SOLVED: To provide a connection structure capable of preventing fracture of a holding hole due to secular deformation of a member, loads or the like and maintaining the soundness of a building when working the holding hole on a surface of the member in order to fit a projection part of a metal fitting, and a pressure isolation plate used in the same. <P>SOLUTION: In order to connect one material 31 and the other material 41 both in a rod shape, a structure uses: a metal fitting 11 comprising a front surface plate 12 provided with projection parts 14 to be fitted to holding holes 33 of the one material 31 and side face plates 17 to be inserted to slits 42 of the other material 41; a fixture 25 such as a bolt for fixing the metal fitting 11 to the one material 31; and pins 46 such as drift pins for fixing the metal fitting 11 to the other material 41. In the structure, pressure isolation plates 21 which are to be fitted to housing grooves 35 provided on the surface of the one material 31 and are provided with inner holes 22 for fitting the projection parts 14 are incorporated. By the pressure isolation plates 21, the loads acting on the projection parts 14 are distributed and transmitted to the one material 31, the loads acting on the holding holes 33 are reduced, and the fracture is prevented. <P>COPYRIGHT: (C)2012,JPO&INPIT |
