PROBLEM TO BE SOLVED: To provide a reinforcing implement capable of maintaining soundness of a connecting part and further capable of dealing with a dimension error of a member even when a lag screw buried in the member cannot resist a tensile load any more.SOLUTION: In a reinforcing implement, a lag screw 51 is buried in lateral holes 33 and 43 extending from a contact surface B between one material 31 and the other material 41 and used in a connecting part where the one material 31 and the other material 41 are made closer by a stud bolt 20 or the like. The reinforcing implement comprises a contact plate 11 which is disposed while confronted with the contact surface B with the lag screw 51 interposed therebetween and is brought into contact with the one material 31 or the other material 41, a crown body 15 in contact with the contact plate 11, an outer nut 24 which presses the crown body 15 towards the contact surface B, and the like. In the contact plate 11, a through hole 12 is provided. The crown body 15 is composed of a tubular part 18 in contact with the contact plate 11, and a closing plate 17. Even if the lag screw 51 cannot resist a tensile load any more, the contact plate 11 presses the one material 31 or the other material 41, such that the reinforcing implement is capable of maintaining soundness of the connecting part. |
