<P>PROBLEM TO BE SOLVED: To provide a fall prevention structure which prevents a ceiling backing material from falling when a hanger member connecting a hanging bolt to the ceiling backing material is damaged due to an earthquake or the like. <P>SOLUTION: A fall prevention structure 1 prevents the ceiling backing material of a ceiling structure from falling, the ceiling structure comprising a hanging bolt 7 suspended from a ceiling 6 and a hanger member 8 suspending and holding the ceiling backing material, a lattice body 10, to the hanging bolt 7. The fall prevention structure comprises a fitting 18 capable of attaching to the hanging bolt 7 and connection means 19 connecting the fitting 18 to a ceiling joist retainer member 9 constituting the lattice body 10 so as to make the fall prevention structure 1 into a simple and easily mountable structure. Consequently, the lattice body 10 and a ceiling panel 11 are prevented from falling, the workability and safety of the fall prevention structure 1 can be improved, and also the fall prevention structure 1 can be applicable to an existing ceiling structure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
