HANGING BOLT SUPPORT DEVICE

摘要

PROBLEM TO BE SOLVED: To fit the upper end part of a hanging bolt to a horizontal member installed at a high lift from a far lower position.

SOLUTION: The upper end part of the hanging bolt 6 is screwed into the screw hole 41a of a lower metal fitting 40 from the lower side and moved forward slightly upward. A worker manually holds the lower part of the hanging bolt 6, inserts the plate part of the horizontal member at the high lift between the support parts 44 and 45 of the lower metal fitting 40 and the holding parts 54 and 55 of an upper metal fitting 50, and further moves upward the upper end part by twisting the lower part of the manually held hanging bolt 6 to press the upper plate 51 of the upper metal fitting 50 by the upper end 6a of the hanging bolt 6 so as to rotate the upper metal fitting 50. Thus, the plate part of the horizontal member can be held by the support parts 44 and 45 and holding parts 54 and 55.
