Abstract

(57) [Abstract] [Purpose] To provide a unit floor tile for wiring electric cables for office automation equipment on a building floor. [Structure] A plurality of plastic sheet pieces or blocks (14, 16, 18) are arranged and adhered on a square base material (12) at predetermined positions, and two first plastic sheets extending in parallel in the longitudinal direction are provided between the blocks. Wiring groove (20) is formed, and two second wiring grooves (22) extending in the lateral direction orthogonal to the first wiring groove are formed. A spacer (24) or a cable cover (26) is fitted flush with the groove (20, 22). Cover the building floor with unit floor tiles (10), remove the spacer (24) or the cable cover (26) to form a desired continuous wiring pattern, house the cables, and then cover the cable covers (26).

Description

[Detailed description of the device]

[0001] With the spread of the background and problems recent OA equipment of the present invention, it is necessary to wire the power lines and communication lines for OA equipment work area floor. For this reason, it was necessary to install semi-permanent wiring equipment in advance on the building floor itself, or to provide a double work floor above the building floor and wire between the bill floor and the work floor. However, in such wiring equipment, it is difficult to change the wiring according to the addition of OA equipment and the change of location, and it is expensive to install new wiring equipment.

Therefore, the present invention makes it possible to easily perform floor wiring on a building floor without such floor wiring equipment at a relatively low cost, and even after the installation, the wiring can be changed by adding or changing the location. Provide unitized wiring floor tiles for building a building floor that can be easily done.

The present invention relates to a unitized floor tile for wiring electric cables for office automation equipment on a building floor. The floor tile is manufactured by adhering a plurality of pieces of flexible plastic sheet having a predetermined thickness at intervals on the surface of a square base material. The wiring groove is formed between adjacent plastic sheet pieces, and has two first wiring grooves that extend in parallel in the longitudinal direction at a predetermined interval and are orthogonal to the first wiring groove at a predetermined interval. It is composed of two second wiring grooves extending in parallel to the lateral direction. Normally, spacers for filling unused wiring grooves and keeping tiles flush are removably fitted in the wiring grooves.

DESCRIPTION OF SPECIFIC EXAMPLES FIG. 1 is a perspective view of a wiring floor tile unit 10 of the present invention. The tile unit 10 is, for example, a square having a side length L of 50 cm, and a plurality of plastic sheet pieces each having a predetermined thickness, for example, 13.5 mm, on the surface of the non-stretchable substrate 12 having a thickness, for example, 1.5 mm. 14, 16 and 18 are adhered to predetermined positions on the surface of the base material, and the first wiring groove 20 and 20 in the vertical direction and the second wiring grooves 22 and 22 in the horizontal direction are orthogonal to the first wiring groove. It is formed between adjacent plastic sheets. In this specific example, the width W of the wiring grooves 20 and 22 is 30 mm and the depth is 13.5 mm, but these dimensions can be changed as required.

As shown in the plan view of FIG. 2, the two vertical wiring grooves 20 and 20 and the two horizontal wiring grooves 22 and 22 are formed in a lattice shape orthogonal to each other. When the floors are spread with a large number of units 10, continuous groove lines are formed at equal intervals in the vertical and horizontal directions. The distance L is 1/4 of the length L, so that the center distance between the two wiring grooves 20, 20 and 22, 22 of the same set is equal to 1/2 of the side length L. In order to form such a grid pattern wiring groove, the plastic pieces 14 arranged at the four corners of the base material are squares each having a side length equal to (L-2W) / 4. The sheet 16 arranged between the sheet pieces 14 at the four corners has a short side equal to (L-2W) / 4 and a long side twice the short side. The sheet piece 18 located in the center of the tile 10 is a square whose one side length is (L−2 W) / 2.

In a preferred embodiment, the base material 12 is made of a highly-filled plastic sheet having a specific gravity of 1.5 or more containing a filler such as calcium carbonate or barium sulfate. This improves the sound insulation performance of floor impact sound in the low frequency range. The relatively thick plastic sheet pieces 14, 16 and 18 adhered thereon are filled with 20% or more of wood powder for weight reduction. It may be foamed to further reduce the weight. This improves sound absorption performance in the high frequency range. Alternatively, the sound absorbing performance can be further enhanced by incorporating 20% or more of a plasticizer.

In order to keep the tile surface flush when the wiring grooves 20 and 22 are not used, a spacer member 24 having the same cross section as that of the groove is fitted in the grooves 20 and 22. When accommodating the electric cable in the wiring groove, these spacer members are removed to accommodate the cable in the groove, and the cable is covered with an inverted U-shaped cable cover 26 having the same cross section as the groove. Alternatively, the cable cover 26 may be fitted in the grooves 20 and 22 at all times.

In use, the building floor is continuously covered with the units 10, the spacers 24 or the cable covers 26 are removed from the wiring grooves 20 and 22 to make the wiring grooves continuous, and after the cables are accommodated, the cable covers 26 are used. Then tile floor 10 with a floor mat or carpet. The intersection of the wiring grooves 20 and 22 becomes the wiring access point.

After the wiring floor is once formed with the unit tiles 10, a place where it is desired to change the wiring pattern for the addition of equipment or the relocation of the installation place is used after removing the uppermost mat or carpet. A new wiring pattern may be formed by using the wiring grooves 20 and 22 which are not present, and then covered again with a mat or carpet.

As described above, by using the unitized wiring floor tile of the present invention, not only can floor wiring equipment be newly installed at low cost, but also subsequent wiring pattern changes can be made in a short time. Can be easily dealt with.
