SHEET METAL REPAIRING STRUCTURE OF HIGH TENSILE STEEL SHEET AND SHEET METAL REPAIRING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a sheet metal repairing structure of a high tensile steel sheet in which the rigidity of the high tensile steel sheet is made durable to the shrinkage force of putty by assisting the rigidity of the high tensil steel plate to attain rigidity equal to that when the sheet thickness is increased and to suppress the expansion of the high tensile steel sheet due to heat in the drying of the putty.;SOLUTION: The sheet metal repairing structure of the high tensile steel sheet is formed by applying a rigidity assisting agent 3 consisting essentially of an ultraviolet-curing resin on a recessed part 2 of the high tensile steel sheet 1, irradiating the rigidity assisting agent 3 with ultraviolet light to harden the rigidity assisting agent, applying the putty 4 for the sheet metal repairing on the recessed part 2 on which the layer of the hardened rigidity assisting agent 3 is formed and drying the putty 4.;COPYRIGHT: (C)2008,JPO&INPIT
