PURPOSE: To combine a thermal fusing of a thermally sealed part and a spatula sealing by mounting a thermal sealing spatula on a flame jetting nozzle of a hand burner head.
CONSTITUTION: A thermal sealing of an end of an asphalt sheet mutually jointing part 1 is carried out by means of a thermal sealing spatula which is mounted on a flame jetting nozzle of a hand burner head to provide an asphalt water proofing. At this time. the thermal sealing spatula 4 is attached detachably to a flame jetting nozzle which is mounted on a head of a hand burner. This thermal sealing spatula 4 is inserted little by little in the slantwise direction from a tip end of a nozzle cover of the hand burner, raised back up to a horizontal position, and fixed to a jetting nozzle by fastening a butterfly screw 7 slightly. The hand burner with the thermal sealing spatula is pasted and piled on one by one into a sheet, and a stepped part of the sheet is applied to a guide softly. Then flame is jetted to heat and melt, asphalt, whereby a thermal sealing is carried out.
