PURPOSE:To inspect efficiently a Z-shaped steel sheet pile on a refining floor, to grasp exactly a quantity of a material which requires a recorrection, and to eliminate waste of recorrection, by maintaining the flatness of a flange face, lifting the Z-shaped steel sheet pile in the air from the floor face, and inspecting its bending in the longitudinal direction. CONSTITUTION:A prescribed number of lifting devices 3 for lifting a Z-shaped steel sheet pile 1' in the air from the floor face, maintaining the flatness of a flange F face of the steel sheet pile 1' are provided on a refining floor 2 of the post-stage of a correcting machine, and when a Z-shaped steel sheet pile 1 carried on the refining floor by a transfer (omitted in the figure) is lifted (a position of (c)), an extent of a quantity (a) or (a') of bending can be inspected. |
