PROBLEM TO BE SOLVED: To provide a highly cost-effective ceiling runner and a light gauge steel ceiling structure using the ceiling runner, the ceiling runner ensuring ceiling runner functions to be performed, enhancing workability, and reducing weight.SOLUTION: A ceiling runner is used on a ceiling of light gauge steel, and installed on an interior wall, with a longitudinal direction of the ceiling runner deemed as a longer-side direction. A vertical cross-section of the ceiling runner includes a bottom side part R11 extending in the longitudinal direction, a side part R12 extending upward from the bottom side part R11, and a bent processed part R13 continuing from an upper edge of the side part R12 and extending in the longitudinal direction. The bent processed part R13 is formed by performing curved-surface processing on a part in contact with an edge part in the longer-side direction of a ceiling joist N1, along the longer-side direction.SELECTED DRAWING: Figure 1 |
