The groove 39 is vertically movably fitted. This groove 39
Are provided over the entire length of the duct main body 9 in the longitudinal direction in order to fit members for connecting the duct main bodies 9 to each other.

The flange 16 is provided coaxially with a tapered hole 40 having a large diameter at the upper portion and a screw hole 41 connected to the lower end of the tapered hole 40. A screw member 42 having a dish-shaped head 42a at the upper end corresponding to the tapered hole 40 is screwed into the screw hole 41 so as to be able to advance and retreat.
An operation groove 45 is provided on the upper surface of the. The horizontal plate portion 37 of the holding member 37 is provided below the screw member 42.
A small-diameter shaft portion 42b penetrating through c is coaxially and integrally connected via a step portion 42c. Further, a washer 43 is interposed between the step portion 42c and the horizontal plate portion 37c, and a retaining ring 44 which is in contact with the lower surface of the horizontal plate portion 37c is fitted to the shaft portion 42b. Thereby, the pressing member 37 is
It is connected to the screw member 42 while allowing the relative angular displacement.

The holding member 37 is formed of the screw member 4
2 moves downward by tightening, and the holding plate 37
The corners of the pair of floor panels 5 and 5 adjacent to each other can be held down by a, so that the wiring duct 1 and the floor panel 5 adjacent to the wiring duct 1 can be firmly connected in this state. it can. When releasing the connection state, the screw member 42 is loosened and the pressing member 37 is released.
Is moved upward to release the pressing of the floor panels 5 and 5 by the pressing plate portion 37a. Then, the floor panel 5 can be removed from the floor surface 7.

Next, the operation of this embodiment will be described. By combining the wiring duct 1 and a large number of floor panels 5, the wiring space 32 below each floor panel 5 is effectively used to increase the wiring capacity. And connection to each electric device can be freely and efficiently performed. In addition, if the equipment and the like are not installed on the line on which the wiring duct 1 is laid, the lid 10 can be easily opened and closed. Maintenance can be easily performed.

Furthermore, since the corners of the pair of floor panels 5 and 5 that contact the outer ends of the flanges 16 in the wiring duct 1 are pressed by the pressing members 37, the wiring duct 1 is connected to the wiring duct 1 by a relatively small number of pressing members 37. Thus, the connection state with many floor panels 5 adjacent to the wiring duct 1 can be maintained.

In the above embodiment, the wiring duct 1 which is linear has been described, but the linear portion has a cross shape.
The present invention is also applicable to a wiring duct connected in a T-shape or an L-shape.
