[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double floor panel for forming a double floor for wiring or the like.

[0002]

2. Description of the Related Art In recent years, various types of O are especially used in offices and the like.
Many electric appliances such as A appliances are introduced. The installation or wiring of these electric devices is performed separately from the interior of the building, and the simplest method of these wirings is to arrange a cable directly on the floor. However, arranging a large number of cables on the floor surface is problematic in terms of safety and aesthetics, and is an obstacle in realizing a comfortable office space or living space. For this reason, the floor is formed in a double structure, and these cables are arranged in the floor. Conventionally, a double floor panel in which a cross-shaped groove is formed on the upper surface has been proposed as a component of this type of double floor, and a plurality of such double floor panels are spread on a floor base to form a double floor. Constructing the floor has been done. In this double floor panel, by laying a plurality of them, a cross-shaped groove is connected to another cross-shaped groove to form a wiring groove, and wiring of electric equipment is performed in this wiring groove. It is configured. Also, by covering the upper part of the cross-shaped groove of the double floor panel with the lid, the entire upper surface of the double floor panel is formed flat.

[0003]

However, in the case of a double-structured floor formed as described above, the double-floor panel placed thereon rises when there is unevenness in the floor foundation. In addition, there is a problem in that the entire lower surface of the double floor panel does not abut against the floor substrate and the floor structure becomes unstable. The present invention
The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a double-floor panel capable of forming a stable floor structure without a double-floor panel being lifted even when there is unevenness in a floor substrate. I do.

[0004]

According to a first aspect of the present invention, there is provided a double-floor panel according to the first aspect of the present invention, which is used by laying a plurality of floors on a flat surface. In a double floor panel in which a wiring groove is formed so as to be continuous with a groove of the double floor panel and an upper portion of the groove is covered with a lid, a bottom plate constituting a bottom of the cross-shaped groove The part has four rectangles that form the side walls of the cross-shaped groove.
Are formed along the periphery of the divided panel portion . The panel for a double floor according to claim 2,
The panel for a double floor according to claim 1, wherein
At the end in the direction in which the groove extends in the width direction of the groove.
In the middle and another switch in the direction the groove extends.
A lit is formed .

[0005]

The double floor panel according to the first aspect is divided into a bottom plate portion forming a bottom portion of a cross-shaped groove formed on an upper surface thereof.
A slit penetrating from front to back is formed along the periphery of the panel portion . Therefore, if there is unevenness in the floor foundation , each split panel part of the double floor panel
And it is displaced surely and touches the floor base in a state of being adjusted. The panel for a double floor according to claim 2 is provided on a bottom plate portion of a cross-shaped groove.
At the end in the direction in which the groove extends, and at the center in the width direction of the groove.
Position another slit in the direction in which the groove extends
Are formed. Therefore, when there is unevenness in the floor substrate
In addition, a slight deformation occurs at the edge of the double floor panel.

And a body 18. The lids 17 and 18 cover the upper part of the cross-shaped groove 2 to form the entire upper surface of the double-floor panel 1 as a flat surface. On the lower surface of the rectangular lid 18, elongated ridges are formed at both ends in the width direction in the longitudinal direction, and the ridges are fitted into the respective fitting grooves 1 of the steps 3a, 4a, 5a, and 6a.
It is a configuration to be fitted to 2 and 12. Also, a square lid 1
On the lower surface of 7, a cross-shaped ridge (not shown) is formed so as to fit into the fitting groove 11. These lids 17, 1
Reference numeral 8 is different from the above-described embodiment and is formed only of a resin such as PP.

The panel 1 for a double floor constructed as described above.
To construct a double floor as shown in FIG. First, a sheet for absorbing fine irregularities is laid on the floor substrate and bonded, and then the border member 23 is placed at a predetermined position on the sheet.
And the slope base 35 is placed. Border member 2
3 and double floor panel 1 inside slope base 35
And four recesses 10 formed in the center of four double floor panels 1 as shown in FIG.
The connecting member 24 having four projections fitted into the holes 9 is fitted into the portion consisting of the double-walled floor panels 1 to connect the double floor panels 1 to each other. After the double-floor panel 1 is spread over the entire surface of the sheet, as shown in FIG. 9, in the wiring groove 25 in which the cross-shaped groove 2 is continuously formed, each wiring groove partitioned by the wall portion 30 is formed. 25, the electric wires 36, 36 or the electric wire 3
7 and 37 are provided. In this case, the separator 33 is arranged at a portion where the strong electric wire and the weak electric wire intersect at the position of the support column 31, and the strong electric wire 36 is arranged above the flat plate portion 33a.
The weak electric wire 37 is arranged below the flat plate portion 33a. Next, the ridges of the lid 17 are fitted into the fitting grooves 11 of each double floor panel 1 and the lower surface of the lid 17 is
, The protrusions of the cover 18 are fitted into the fitting grooves 12, and the lower surface of the cover 18 is brought into contact with the upper end of the wall 30, thereby covering the upper part of the wiring groove 25. Finally,
A carpet or the like is laid on the double floor panel 1 and the lids 17 and 18.

In the double floor formed by laying a plurality of double floor panels 1 of this embodiment, since the slits 7 are formed in each individual double floor panel 1, there is unevenness in the floor base. Also in this case, since the double floor panel 1 is slightly deformed at the slit 7 to have a flexible shape along the floor substrate, the double floor panel 1 does not rise and is adapted to the floor substrate in a conformable state. Contact and a stable floor structure can be formed. In the double floor, since the separator 33 is arranged at the center of the cross-shaped groove 2, the strong electric wire 36 and the weak electric wire 37 can cross each other three-dimensionally, so that generation of noise and the like can be prevented. Further, since the wall portion 30 is formed in the cross-shaped groove 2, different kinds of electric wires can be arranged in the same cross-shaped groove 2 and the electric wires can be prevented from being entangled.

[0019]

The double floor panel according to the first aspect of the present invention is used by laying a plurality of panels on a flat surface, and a cross-shaped groove formed on the upper surface thereof is connected to a groove of another double floor panel. In a double floor panel in which a wiring groove is formed and the upper part of the groove is covered with a lid , side walls of the cross-shaped groove are formed in a bottom plate part forming the bottom of the cross-shaped groove. Two rectangular
