PROBLEM TO BE SOLVED: To install a lifting hardware in a recessed groove of a deck plate free to adjust, temporarily stop it at the time of construction and facilitate installation work. SOLUTION: A pair of left and right engagement bodies 1 to engage is provided in the inside of a groove Q. A suspension body 2 is connected to a connecting shaft 3 to axially support these engagement bodies 1 free to open and close free to oscillate. A lifting bolt P is suspended on the suspension body 2. Additionally, the engagement bodies 1 are constituted of a pair of left and right engagement projections 1A to engage with the inside of the groove Q and a pair of left and right connecting parts 1B to connect the engagement projections 1A to each other by respectively extending from the engagement projections 1A. Thereafter, the connecting parts 1B are fixed to each other free to open and close by an adjustor 4, and extension opening width of the engagement projectior 1A is adjusted by an opening and closing angle of those connecting parts 1B. The adjustor 4 is constituted of a countersunk bolt 4A to horizontally pass through the connecting parts 1B respectively and a nut 4B. |
