FILLING REPAIR METHOD FOR CLEARANCE PART IN BUILDING AND FILLING REPAIR DEVICE USED IN SAID METHOD

摘要

PURPOSE:To prevent a crack and exfoliation by injecting hot air preheating a clearance part in a building thereafter forcing melted paraffin to be press fitted into the clearance part. CONSTITUTION:Paraffin in a melted condition is contained in a vessel 18. Next hot air is blown to a clearance in construction of a structure from a jet port of an injecting jig 10a in an injection control part 8, heating a peripheral edge of the clearance in construction. Subsequently, an air compressor 34 is driven pressing down a piston giving a delivery pressure to the paraffin in the vessel 18. And adjusting a knob 38 jetting an optimum amount of paraffin, the clearance is filled in its inside with the paraffin. Further when the paraffin adheres to a mouth part of the clearance in a swelling condition, an injecting jig 10b, provided with a brush in a mouth end of a jet port 9, is connected, injecting hot air from the jet port, and the paraffin, while it is maintained in a melted condition, is spread extending by the brush.
