PROBLEM TO BE SOLVED: To provide a reinforcement brace connecting metal fitting of the suspended ceiling capable of suppressing the occurrence of outer-surface falling in a lower end side joining part of a reinforcement brace.SOLUTION: A reinforcement brace connecting metal fitting 15 of the suspended ceiling is provided for connecting the lower end side of a reinforcement brace 7 to a ceiling backing 6 of assembling a main steel material 1 extended in horizontal one direction T1 and a connection steel material 5 extended in the other direction T2 in a lattice shape, and comprises substantially orthogonally arranged one sidewall plate part 17 and other sidewall plate part 16, and comprises four reinforcement brace connecting metal fitting pieces 18 formed in a substantially L shape. The reinforcement brace connecting metal fitting pieces 18 are respectively installed in four recessed corner parts 20 of arranging the main steel material 1 and the connection steel material 5 in a cross shape by connecting the one sidewall plate part 17 to the main steel material 1 and the other sidewall plate part 16 to the connection steel material 5, and are constituted so as to connect the lower end side of the reinforcement brace 7 to the one sidewall plate part 17 and the main steel material 1 and/or the other sidewall plate part 6 and the connection steel material 5.SELECTED DRAWING: Figure 1 |
