APPRATUS FOR CORRECTING ANCHORING BAR BY WELDING DISTORTION

摘要

The present invention relates to an apparatus for correcting welding distortion of an anchoring bar welded onto a wall of a cargo in an LNG carrier. Conventionally, the welding distortion is corrected by a hammering operation after welding the anchoring bar, thus there are great problems such as noise generation, musculoskeletal diseases of workers, and the like. The present invention comprises: two wrenches for adhering to a wall and the anchoring bar by applying the structure of a pipe wrench; a correction apparatus body in which the two wrenches to both sides of the upper surface thereof; and a wrench nut screwed to a screw part of the wrench on the upper surface of the correction apparatus body. The wrench is pushed by turning the wrench nut, thereby correcting the welding distortion.
