Claims

[Claim for Utility Model Registration] In a ceiling suspension structure in which a ceiling base 2 is suspended below an upper floor structure 1 via a hanger system, a dovetail groove 14 is formed extending in the longitudinal direction at the bottom of the upper floor structure. On the other hand, the hanger system has a pair of arm parts 31, 31 connected in a U-shape with an engaging part 32 corresponding to the cross-sectional shape of the dovetail groove 14.
It consists of a stopper 3 at the tip of the stopper and a hanging bolt 4 that is screwed into the connecting part 33 of the stopper and extends vertically between the pair of arm parts 32, 32. is inserted in parallel into the dovetail groove 11 by pressing inward, and after rotating 90 degrees, releasing the inward pressure, the tip engaging portion 32
, 32 are engaged with the dovetail groove 11, and the tip 41 of the hanging bolt 4 is interposed between the engaging parts 32, 32 to prevent the stopper 3 from rotating, and the hanging bolt 4 is screwed in. A ceiling hanging structure characterized in that it is fixed by pushing up the bottom of the dovetail groove 14 with its tip 41.
