PURPOSE:To facilitate the change of floor wiring, by using a block member having a distribution board combined with a box and embedded in a floor, in place of a part of square block members having leg sections laid on the floor of a lower layer. CONSTITUTION:In place of a part of a plurality of block members 1 arranged vertically and horizontally, a double floor box consisting of a box main-unit 10 and an upper surface cover 11 is set. In the box main-unit 10, a distribution board 3 embedded in the floor is contained. Wiring to an upstream power source and a downstream load is connected to the distribution board 3, and in the board 3, a breaker 15, terminal plates 16, 17, and the like are contained. On the upper side of the upper surface cover 11, a carpet 9a is laid so that the upper side may be flush with the upper surface of the block members 1. The upper surface cover 11 is provided with handles 12, and is easily removed from or fitted on. As a result, wirings through a floor section are arranged increasingly and easily. |
