Abstract:
PROBLEM TO BE SOLVED: To solve the problem in which, in the conventional method of fixing a terminal end of a rolled steel plate, it was not easy to fix the terminal end of the rolled steel plate at the time of manufacturing and to release the terminal end of the rolled steel plate at the time of use.SOLUTION: A rolled steel plate (coiled body) 1A comprises: holes 102A, 102B which are engaged parts formed at a terminal end 101 of the rolled steel plate 1A; and cut-and-raised pieces 103A, 103B which are engaging parts formed on a steel plate S of a layer on the lower side of the holes 102A, 102B of the steel plate S. Because the terminal end 101 of the rolled steel plate 1A is fixed to the rolled steel plate 1A by passing the cut-and-raised pieces 103A, 103B through the respective holes 102A, 102B and folding back these pieces to the terminal end side, it is possible to automatically perform the fixing process of the terminal end 101 without human intervention at the time of manufacturing the rolled steel sheet 1A and to easily release the terminal end 101 at the time of using the rolled steel sheet 1A.SELECTED DRAWING: Figure 1
