STEEL-REPLUMBING ADJUSTMENT JIG

摘要

PROBLEM TO BE SOLVED: To provide a steel-replumbing adjustment jig ensuring adjustment of horizontal positions through the fine-tuning of the movement of an erection piece by means of a simple arrangement and operation, and being excellent in durability. SOLUTION: A horizontal adjustment device 4 for slidably supporting a slide plate 22 by means of a support frame 21 is provided on the upper mounting part 9 of the jig 1, the slide plate 22 having wedge-shaped right and left pawl parts 30 and 31 formed integrally therewith, with the pawl parts capable of abutting against both sides of an upper erection piece 65. The slide plate 22 is slid against the support frame 21 to selectively insert the right and left pawl parts 30 and 31 into both sides of the upper erection piece 65 to thereby move the upper erection piece 65 gradually and horizontally in opposite directions, so as to adjust the horizontal position of an upper steel pole 62 relative to a lower steel pole 61.
