CURING JIG FOR MELT CUTTING SPARK OR THE LIKE AND CURING METHOD

摘要

PROBLEM TO BE SOLVED: To obtain a curing jig with simple construction and a curing method capable of carrying out melt cutting work easily in every part without requiring any large-scaled curing downward of cutting section. ;SOLUTION: A curing jig 10 formed by spreading a fire resistive sheet 15 on umbrella-like bones 14 provided to the center bar in an openable manner is used, the fire resistive sheet 15 is positioned downward of a melt cutting section 21 of a metal member 20 to be meltingly cut in a state to open the bones 14 of the curing jig 10, and ignition sparks are received by the fire resistive sheet 15 positioned downward by meltingly cutting the metal member 20 from above.;COPYRIGHT: (C)1997,JPO
