2. Description of the Related Art A cross-shaped or cross-shaped wiring groove is formed on the upper surface of a rectangular panel having a required thickness, and the upper surface of the wiring groove is covered with a cover plate to make the upper surface of the panel flat. There is a floor wiring apparatus in which a panel is laid directly on the floor to form a grid-like wiring groove formed by continuation of the wiring grooves of each unit panel on the entire floor, and an electric wire is accommodated in the grid-like wiring groove. The cover plate covers only the upper surface opening of the wiring groove (for example, Japanese Utility Model Application Laid-Open No. 56-71839 and Japanese Utility Model Application Laid-Open No. 62-131037). One that covers the upper surface opening of the wiring groove by overlapping on the rectangular panel (for example,
2-29722).

[0003] Instead of laying the above-mentioned square unit panel having cross-shaped or cross-shaped wiring grooves on the floor, substantially square blocks for forming wiring grooves having a flat upper surface are arranged and fixed at predetermined intervals on the floor to form a grid. It is also known to form a wiring groove (for example, Japanese Utility Model Laid-Open No. 64-2519). In short, there is a floor wiring apparatus in which a grid-like wiring groove is formed on the floor surface by a regular multi-island arrangement of a number of substantially rectangular blocks, and the upper surface opening of the wiring groove is covered with a cover plate and the upper surface is flat. Various are known.

In addition, a spacing member such as a support or a block is arranged on a floor surface, a floor panel is stretched thereon to form a double floor, and electric wires are stretched around a space between the floor and the floor panel. There is also a floor wiring apparatus (for example, JP-A-60-112954).

In the above floor wiring device, the width of the wiring groove is not so large because the weight of the furniture and equipment and the weight of the pedestrian are applied to the cover plate covering the wiring groove. Therefore, the electric wire accommodation capacity of the wiring groove is limited. In order to increase the wire capacity of the wiring groove, it is necessary to increase the depth of the wiring groove, that is, to increase the height of the unit panel or block. -It will be burdensome during construction, and the height to the ceiling will be low, thus narrowing the indoor space.

As a means for solving the above-mentioned problem, it is conceivable to increase the width of the wiring groove without changing the height of the unit panel or the block. Can not stand. If the height of the unit panel or the block is not changed, the weight of the unit panel or the block is reduced due to the widening of the wiring groove, but the weight of the cover plate increases due to the increase in the plate thickness, which makes it difficult to handle the cover plate. In addition, as the thickness of the cover plate increases, the electric wire accommodation capacity of the wiring groove decreases.

[0007]
