PURPOSE:To easily extend a cable in a wiring pit on a finishing material by forming the steel plate of an intersection disposed at the optimum position to access a cable in the pit separately from the material. CONSTITUTION:A wiring floor material 10 having a predetermined wiring pit 11 opened above is laid on a floor face F, a soft finishing material 20 is directly placed on the upper face of the material 10, and the surface of the floor F is absorbed by the flexibility of the material 20. A steel plate 23 placed in an opening except the intersection of the pit 11 is lined on the material 20 thereby to cover the opening of the pit 11, and the steel plate 30 of the intersection of the pit 11 is formed separately from the material 20. Thus, a cable can be extended from the intersection of the optimum position to access the cable in the pit 11. |
