A duct for electrical wiring in a building is provided to stably fix cables received under a wire separation plate by pressing the cables with an up and down separator. A duct for electrical wiring in a building includes a duct body(10), a wire separation plate(20), an up and down separator(30), and a cover(40). The duct body includes a bottom plate(11), vertical plates(12) formed on both ends of the bottom plate, a fixing end(13), an insertion groove inside the fixing end, a plurality of bolt holes(15) outside the fixing end, a fixing bolt(16) fixed to a concrete slab, and a plurality of hemispherical projections(17). The wire separation plate includes a triangular bent unit(21), lateral fixing ends(22) on both ends of the triangular bent unit, and a plurality of cutting grooves(23). The up and down separator includes an elastic bar(31), a bent unit(32), and a shock absorber. The cover includes an elastic plate(41), insertion ends(42) on both ends of the elastic plate, and a plurality of space separation projections(43). A cable(6) is received on a groove part of the triangular bent unit. The up and down separator is positioned on the groove part to receive the cable in two steps. The space separation projections of the cover contact with an upper end of the triangular bent unit to separate spaces on which the cables are installed. |
