A unity cable protection duct installed inside a wall of a building is provided to minimize a phenomenon to transmit the noise between households through the duct and to improve insulation property by separating wires inside the duct. A unity cable protection duct installed inside a wall of a building includes a terminal box case(10), a sealing plate(20), a wire pipe(30), a support plate frame(40), a fixing plate(50), and an arranging fixing rack(60). The terminal box case(10) is a case forming a terminal box where unity cables are collected. The sealing plate(20) prevents the inflow of concrete putted to the terminal box case(10) to form a wall body. The unity cables are flown into the wire pipe(30). The support plate frame(40) supports a plurality of wire pipes(30). The fixing plate(50) fixes the wire pipe(30) to the support plate frame(40). The arrangement fixing rack(60) fixes the terminal box case(10) to a horizontal arranging reinforcing rod. |
