A duct structure for a floor wiring of a building is provided to facilitate installation, to control capacity without a loss of a floor panel after installation, and to obtain a beautiful appearance. In a duct structure for a floor wiring of a building, a duct body(10) consists of one pair of left and right pipes. The pipes are semicircular-shaped. Working spaces(11,11a) are formed on left and right sides. An anchor hole(12) is formed in a center of the duct body(10). The anchor(12a) is inserted in the anchor hole(12). A rubber plate(13) is adhered on a floor of the duct body(10). Wiring pipes(14) are coupled and fixed to each other and are elongated toward a front and rear of the duct body(10). A wiring(14a) is inserted in the wiring pipe(14). Open parts(15,15a) are formed on each working space(11,11a). Coupling bolts(16) are erectly fixed to an adjacent front end of the open part(15,15a). A nut(16a) is inserted in the coupling bolt(16). A duct cover(20) is inserted in the open part(15,15a) of the duct body(10). The duct cover(20) is a squared pipe. In the duct cover(20), wing parts(21,22) are formed on left and right side ends of an upside. The wing parts(21,22) is closely contacted to be adjacent to the open part(15,15a). Bolt hole(21a,22a) are formed on the wing part(21,22). The coupling bolt(16) is inserted in the bolt hole(21a,22a). A step(23) is formed inside a center of the duct cover(20). A sealing cover(24) is received on the step(23) to seal each working spaces(11,11a). |
