PROBLEM TO BE SOLVED: To make it possible to very simply interlock a metal fixture with a deck plate of the ceiling section with one touch control and to strengthen interlocking strength of the metal fixture to promote load resistance to the ceiling material. SOLUTION: A ceiling material mounting device is constituted of a metal fixture 1 and a hang bolt 2. Then, the metal fixture 1 is constituted of the central plate section 4 having a screw hole 3, upward plate sections 5 provided so as to bend upward on both right and left end edges of the central plate section 4, oblong interlocking plate sections 6 interlocking with interlocing recessed fitting sections of deck plates provided so as to bend downward on right and left upper end edges of the upward plate sections 5 and rising plate sections 7 provided so as to rise upward on both front and rear edges of the central plate section 4 and, at the same time, capable of bringing both right and left end edges into contact with the upward plate sections 5. |
