PROBLEM TO BE SOLVED: To obtain a non-connection feeder structure in system ceiling wherein an electric apparatus can be fixed through a gap formed by T bars without removing the ceiling by fixing cable supporting metals to a T bar and forming a core for clamping a cable such that it can be fitted removably over the cable from the lower surface side of ceiling through the gap formed by T bars. SOLUTION: The non-connection feeder structure in system ceiling comprises T bars 1 arranged closely each other and substantially in parallel with each other to form a gap 3 of specified width opening to the lower surface of ceiling, cables 5 laid on the rear surface side of ceiling, and cores 7 for clamping the cables 5. The T bar 1 is fixed with supporting metals 9, a part of cable 5 is held on the rear surface side of gap 3 and the core 7 is formed to be fitted removably over the cable from the ceiling plate face side through the gap 3. Since the core 7 can be clamped to the cable 5 through the gap 3 formed by T bars 1 on the lower surface side of ceiling by simply removing a batten 11, an electric apparatus (e.g. a lighting fixture) can be fixed from the under side of ceiling without removing the ceiling plate 2. |
