[Prior art]

 There is a cross-shaped or cross-shaped wiring groove on the top surface of a rectangular panel with the required thickness, and the top surface of the wiring groove is covered with a cover plate so that the top surface of the panel becomes flat. There is a floor wiring device that is laid on a floor and has a grid-shaped wiring groove formed by connecting the wiring grooves of the above-mentioned unit panels over the entire floor, and the wires are housed in the grid-shaped wiring groove. The cover plate described above covers only the upper opening of the wiring groove (for example, Japanese Utility Model Laid-Open No. 56-71839 and Japanese Utility Model Laid-Open No. 62-131037), and a cover plate of the same shape and size as the rectangular panel with wiring grooves. There is one (for example, Japanese Utility Model Laid-Open No. 52-29722) that overlaps the rectangular panel and covers the upper opening of the wiring groove.

Instead of laying a square unit panel having the above-mentioned cross-shaped or cross-shaped wiring grooves on the floor, a substantially rectangular block for forming wiring grooves having a flat upper surface is arranged and fixed on the floor at predetermined intervals to form a grid pattern. It is also known to form the wiring groove (for example, Japanese Utility Model Laid-Open No. 64-2519). In short, there is a floor wiring device in which a grid-like wiring groove is formed on the floor by a regular multi-island array of a large number of substantially rectangular blocks, and the top opening of the wiring groove is covered with a cover plate to make the top surface flat. Various are known.

[0004] Furthermore, a space for holding columns such as columns and blocks is arranged on the floor surface, and a floor panel is stretched on the space maintenance component to form a double floor, and electric wires are stretched around the space between the floor and the floor panel. There is also a floor wiring device (for example, JP-A-60-112954).

In the above floor wiring device, the width of the wiring groove is not so wide because the weight of the furniture and equipment and the weight of the pedestrian are applied to the cover plate that covers the wiring groove. Therefore, the amount of wires that can be accommodated in the wiring groove is limited. In order to increase the capacity of the wiring groove to accommodate electric wires, the wiring groove should be deepened, that is, the height of the unit panel or block should be increased, but the weight of the unit panel or block increases due to the increase. It will be a burden during transportation and construction, and the height to the ceiling will be low, narrowing the indoor space.

As a means for solving the above problem, it is possible to widen the width of the wiring groove without changing the height of the unit panel or the block, but the cover plate does not have to have a considerably thick plate so that the load / load can be increased. I can't stand a shock. If the height of the unit panel or block is not changed, the weight of the unit panel or block will decrease due to the widening of the wiring groove, but the cover plate will increase in weight due to the increase in plate thickness, and it will be difficult to handle the cover plate. . In addition, the amount of wire accommodated in the wiring groove decreases as the thickness of the cover plate increases.

[0007]

[Problems to be solved by the device]

 The present invention has been proposed in view of the above-mentioned problems in the conventional floor wiring device, and it is possible to increase the amount of electric wires to be accommodated and to reduce the weight of floor wiring device components by widening the wiring groove, and to provide a cover plate for covering the wiring groove. It is an object of the present invention to provide a floor wiring device that can be easily constructed without increasing the thickness.
