PURPOSE:To improve the earthquake resistance through a simple work by constituting a supporting connection part for the connection support in crossing at right angle and an engaging fixation part, at the position where a ceiling backing member is positioned on an equal plane level. CONSTITUTION:A connecting supporting metal fitting is constituted of an engagement fixation part 21 for the engagement in holding form on the upper and lower surfaces of a runner 4, another runner 6 connected in crossing at right angle, and a supporting connection part 25 which is insertion-fixed at the edge part of an installation runner 7. An engagement receiving hook 23, Y-shaped pressing piece 24, and an engaging hook part 24a for the positioning joint are provided at the engagement fixation part 21, and the runner 4 and the connecting supporting metal fitting 20 are rigidly connected. Further, the runners 6 and 7 are placed at the supporting connection part 25, and a positioning projection 25b is installed. Accordingly, the runner 4 can be arranged at a positioned standard position in simple manner, and a supporting means can be installed easily. |
