PURPOSE:To correct efficiently the dislocation in a joint part by passing a T- shaped tension plate into the space of the joint part by utilizing said space, disposing a tension cylinder on the opposite side thereof, pulling the T-shaped tension plate by the tension cylinder and clamping the joint part. CONSTITUTION:A structure A and a structure b are going to be welded. The plate 3 of the T-shaped tension plate C consisting of plate holders 1, 2 and the plate 3 held thereto is passed into the space of the joint between said structures and the tension cylinder D which is constructed to permit engagement and disengagement of the plate 3 of the plate C is disposed on the side opposite from the holders 1, 2 with the joint part in-between. Then the T-shaped tension plate C is pulled by the tension cylinder D to clamp the joint part, thereby correcting the dislocation in the welding joint part. |
