PURPOSE:To prevent exposure of a hole from a clearance made between an L bar and a T bar orthogonal with the former in the case of setting the L bar and the T bar at different height levels by simply, speedily and certainly supporting a ceiling board and improving working performance. CONSTITUTION:A sectional L shaped L bar 2 and a sectional reverse T shaped T bar 3 orthogonal with the L bar are connected to each other by using a connecting metal fitting 11. The connecting metal fitting 11 is formed of a base plate part 12 and a support plate part 13 extending from one end of the base plate part 12 in a direction orthogonal with it. The base plate part 12 is formed below the support plate part 13. A sectional L shaped shielding plate part 17 is integrally formed on the lower end of the base plate part 12 in breadth of a horizontal side 9 of the T bar 3 and along from the head end position of a horizontal side 6 of the L bar 2 to the position of the horizontal side 9 on the head end of the T bar 3. |
