PURPOSE:To obtain a beautiful curved surface shape by fixing a backing member to a backing receiver, previously worked into a curve fold shape, and a fixing member and a long band plate to this backing member by machine screws along the curve fold shape. CONSTITUTION:A hanger bolt 1 is suspended from a body of ceiling, wall, etc., of a building, and a mounting metal fixture 2 is mounted on a lower end of the bolt 1 and fixed by a fixing bolt 8 to a fixture 3 of a backing receiver 4 previously applied with bending work. A backing member 5 is parallelly separation-arranged in such a manner as orthogonal to the lengthwise direction of the backing receiver 4 thus applied with this bending work. Next, a stopper edge 10 of a stopper member 6 is stopped to a stopper groove 17 of a long scale band plate 7, and a curved surface sticking in the lengthwise direction is obtained by arranging both the members 6, 7 in the backing member 5 to be press-deformed to a side of the backing receiver 4. In this way, a smooth curved surface can be prepared. |
