DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an OA floor panel suitable as a floor structure for installing OA equipment such as a word processor, a computer, and a communication apparatus.

[0002]

2. Description of the Related Art In recent years, the development and spread of OA equipment such as word processors, computers and communication equipment have been remarkable. With the development and spread of OA equipment, a large number of power cords and connection cables will be installed indoors. If these power cords are crawled on the floor, they not only impair the aesthetic appearance but also cause tripping and injuries, and cause malfunction of the OA equipment. In view of this, floor panels have been proposed in which a large number of these wires are stored under the floor. For example, as well-known example 1, "O"
Floor panel in "Construction method of floor structure for A". As shown in FIG. 16, this floor panel is formed by forming a plurality of protruding portions 2 that can be cut off at an arbitrary position at predetermined intervals on either the front surface or the lower surface of the floor base plate 1. It is. Then, these floor panels are placed on the floor surface, the wiring 4 is housed in the groove 3 between the adjacent convex portions 2, a part of the convex portion 2 is cut off at a desired position, and the cut portion is passed through the cut portion. The wiring is conducted vertically and horizontally by guiding the wiring to an adjacent groove, and a floor finishing material is laid on the floor panel with or without an intermediate member.

FIGS. 17 and 18 show a known example 2. FIG.
There is a floor panel shown in the figure. FIG. 17 is a top perspective view, and FIG. 18 is a bottom perspective view. This floor panel is provided with legs 7 at the four corners of the lower surface of the floor portion 6 composed of the crosspieces 5 and 5a, intermediate portions thereof, and central portions thereof, and is reinforced by reinforcing rib groups 8 provided on the lower surface. That is, the reinforcing rib group 8 includes reinforcing ribs 9 and reinforcing ribs 10 connecting the leg portions 7, and a vertical rib 11 and a horizontal rib 1 connecting at an intermediate position between the reinforcing ribs 9.
2. It consists of oblique ribs 13, and three reinforcing ribs 9 are provided in parallel. The leg 7 of the reinforcing rib group 8
The lower surfaces of the reinforcing ribs 9 and 10 connecting the
, And is therefore formed in a concave shape between the legs 7. To use the floor panel of the above configuration,
Place the legs 7 on the floor and lay them out.
The power cable is wired through the power cord between the legs 7 in the space between the two.

[0004]

However, the above-mentioned known floor panel has the following problems. That is, in the known example 1, the wiring between the adjacent grooves 3 is
Can be performed by cutting off at an arbitrary position, but it takes time and effort to cut off, and after deciding the position of the wiring in advance, cutting off the convex portion 2 when laying the floor panel accordingly. Other than wiring, it is impossible to wire after laying the floor panel. Further, since the floor surface is not necessarily a horizontal smooth surface, the entire surface of the convex portion 2 is not placed on the floor surface. Therefore, there is a possibility that a part of the convex portion 2 is in a floating state and rattling occurs, and a walking sound is produced.

In the known example 2, unlike the known example 1, a space is provided between the legs 7 so that wiring can be carried out vertically and horizontally even after the floor panel is laid. It is possible to wire while looking at the direction of the power cord. However, since the legs 7 are also provided at the four corners and the intermediate portion thereof, there is a problem that the distance between the legs is narrowed and it is difficult to pass the power cord during wiring. Also, 9
Since there are two legs, not all legs are placed on the floor as in the case of the known example 1, so that there is a problem that the walking sound is likely to be produced by the floating legs. In addition, since it is supported by nine legs, it has sufficient load-bearing capacity and bending strength, but the weight is increased and the cost is increased accordingly.

Further, in the known example 2, as shown in FIG. 17, the reinforcing ribs 9 are parallel and three are provided in parallel. It is 14. For this reason, when the power cord is inserted between the legs 7 in the direction of the arrow, the leading end of the power cord does not necessarily advance linearly between the legs 7, and the leading end that goes obliquely enters the dead end path 14. There is a problem that it has to be redone each time and wiring takes time. Furthermore, since the side surfaces of the floor panels are smooth in both of the publicly known examples 1 and 2, there is a problem in that they are not positioned when laid on the floor surface and are difficult to construct.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides an OA floor panel which has sufficient strength, is easy to be level with the floor surface, and is easy to construct and wire. It is.
