PROBLEM TO BE SOLVED: To hang a ceiling panel using a single-side horizontal flange, easily adjust the height of the ceiling panel after its construction, hardly transmit the vibration of a floor panel to the ceiling panel, and easily attach the ceiling panel with superior operability, when an upper-floor beam is constituted of a steel material having the single-side horizontal flange like a channel steel. SOLUTION: A ceiling hanging hook is provided with an outer member 11 which has rail 11b, extends in the width direction of a steel material in the bottom side of the steel material, and has a lock piece 11c rising upward in its tip, an inner member 12 which is fitted to the rail 11b of the outer member 11 so as to slide only in the width direction and has an eaves part 12c for sandwiching the horizontal flange in a space toward the outer member 11, a hanging tool 13 suspended from the outer member 11 so as to be freely adjusted tool 13. It is also provided with a stopper mechanism which allows the inner member 12 to slide in the direction of narrowing the interval between the eaves 12c and the lock piece 11c and prevents it from sliding in the direction of broadening the interval, and a release mechanism which releases the slide preventing mechanism of this stopper mechanism. |
