PROBLEM TO BE SOLVED: To provide a substrate structure of a suspended ceiling which reduces weight of whole substrate structure by reducing the number of components as much as possible, maintains earthquake resistance, can minimize damage even if falling, and can achieve cost reduction and workability by reducing the number of components.SOLUTION: A substrate structure 1 of a suspended ceiling arranges ceiling finish plates B. The substrate structure of the suspended ceiling includes: a plurality of suspending bolts 2 in which top edge is mounted to a ceiling skeleton A to suspend; a plurality of long joist receivers 4 supported to bottom edges of the suspending bolts 2 via hangers 3 and having a rectangular or E-shaped cross section; and a plurality of long holding members 5 crossing over the joist receivers 4 to be fixed and having the cross section in which at least one flange 5a is formed to hold the ceiling finish plates B. |
