PROBLEM TO BE SOLVED: To provide a ceiling structure capable of solving the problem of insufficient strength of a part for being anchored to an upper structure of an upper end of a hanging bolt.SOLUTION: A ceiling structure 1 includes: a hanging bolt 2 hanging from an upper structure 6; an auxiliary bolt 3 hanging from the upper structure 6 near the hanging bolt 2; a substrate material 43 held in the state of being hung by the hanging bolt 2; and a horizontal sway brace 7 arranged in such a manner as to cross the hanging bolt 2. The hanging bolt 2 and the auxiliary bolt 3 are coupled together via the horizontal sway brace 7 above the substrate material 43. An upper part of a brace 8 is connected to the horizontal sway brace 7. |
