Description

[Detailed description of the invention] [Field of industrial application] The invention facilitates the wiring of power lines, communication lines, etc. to each device in computer rooms, office automation equipment rooms, etc., and also makes it easy to change the wiring of devices. The present invention relates to a floor panel that is easy to handle and can be easily handled.

[Conventional technology]

(b) There is a floor panel in which wiring grooves are formed in the shape of a cross on the opposing surfaces of a pair of upper and lower square boards, and by overlapping the pair of square boards, a tunnel-like wiring path is formed in the shape of a cross between the upper and lower boards ( For example, Utility Model Publication No. 55-27298).

(b) Wiring grooves are provided perpendicularly on the upper surface of the rectangular board, and dovetail grooves are formed on the opening edges of the upper surface of the wiring grooves,
There is a floor panel in which a cover plate is elastically fitted from the upper part of the groove to form a flat upper surface of a rectangular board (for example, Japanese Utility Model Publication No. 56-71839).

[Problems to be solved by the invention] The conventional floor panel with cross-shaped wiring grooves described in item (a) above requires first laying the lower rectangular board on the floor and placing the electric wires in the grooves. After making the necessary wiring, stack and secure the upper rectangular board. In addition, when changing the wiring of a load device, remove the upper rectangular board at the relevant location, change the wiring in the groove of the lower rectangular board, and then attach the upper rectangular board. Since the upper rectangular board and the lower rectangular board have the same shape, size, and substantially the same weight, it is difficult to attach and detach the lower rectangular board, resulting in poor floor panel installation efficiency.

Furthermore, in the floor panel described in item (b) above, the cover plate is elastically fitted into the dovetail groove portion provided at the opening edge of the wiring groove, so it is difficult to attach and detach the cover plate. In particular, it is impossible to attach a cover plate that does not have elasticity.

The present invention solves the above-mentioned problems in the prior art, and aims to improve the efficiency of installing floor panels and to enable quick and easy changes in the wiring system.

[Means for solving problems]

The floor panel of the present invention is a floor panel in which wiring grooves are provided perpendicularly on the upper surface of a rectangular board, and the upper surface opening of the wiring groove is covered with a cover plate to make the upper surface of the rectangular board flat. The cross-shaped cover plate is formed into a letter shape and its surface is covered with a cushioning material, and the cross-shaped cover plate is configured to fit into a section having a substantially L-shaped cross section formed at the opening edge of the wiring groove. do.

[Effect]

When the floor panels of the present invention are spread on the floor, a network of wiring grooves is formed by the interconnection of the wiring grooves of each floor panel.

Furthermore, the floor panels of the present invention are arranged so as to form a predetermined wiring system, and the rest are laid so as to be filled with ordinary floor panels without wiring grooves.

Then, separately house communication lines such as power lines, telephone lines, signal lines, etc. in the continuous wiring groove,
A cross-shaped cover plate is disposed in a drop-down manner on the substantially L-shaped step in cross section at the opening edge of the wiring groove to sequentially cover the wiring groove and make the entire upper surface of the floor panel flat. When changing the wiring, remove the cross-shaped cover plate at the relevant location, change the wiring in the groove under it, and then cover it again with the cross-shaped cover plate.

〔Example〕

FIG. 1 is a perspective view showing an embodiment of a floor panel P according to the present invention, and FIG. 2 is a perspective view of the floor panel P with a cover plate removed.

On the top of a square board 1 with a side of, for example, 50 cm,
A cross-shaped wiring groove 2 is provided at the center thereof to intersect at right angles.

The board 1 is made of an aluminum die-cast board, a laminated asbestos board, a particle board, a concrete board, a gypsum board, a reinforced plastic board, or any combination thereof.

The cover plate 3 has a cross shape so as to cover the cross-shaped wiring groove 2 all at once, and is fitted into the cross section 4 having a substantially L-shaped cross section formed at the opening edge of the groove 2 by dropping it into the cross shape. The top surface of the cover plate 3 is configured to match the top surface of the board 1.

The material of the cross-shaped cover plate 3 may be any material such as hard plastic plate, aluminum plate, or steel plate.
A soft plastic or the like is coated as a cushioning material to improve conformability to the board 1.

Further, the cross-shaped cover plate 3 may be formed into a U-shape in cross section with both side edges 31, 31 bent, as shown in FIG. 3, in addition to the flat plate shown in FIGS. 1 and 2. The rigidity of the cover plate 3 increases.

When a power line and a communication line, that is, a strong electric line and a weak electric line intersect at the center of the cross-shaped wiring groove 2, an overpass-shaped isolation member 5 shown in Fig. 2 is placed at the crossing point to separate the wiring vertically. Voltage-related disturbances can be removed.

A cross-shaped cover plate 3 having a pull-out hole 6 (indicated by a chain line) in a part is used at a position where the wiring is pulled out onto the floor. The cross-shaped cover plate 3 can be attached to the cross-shaped wiring groove 2 by turning it 90 degrees or 180 degrees, that is, there is no directionality for its installation. It is sufficient to provide it on one piece.

Therefore, by changing the mounting position of the cross-shaped cover plate 3 with a pull-out hole and changing its mounting direction, the position of the pull-out hole can be freely changed, so that changes in the branch wiring position can be quickly and easily accommodated. I can do it.

4 and 5 are perspective views showing other embodiments of the floor panel P according to the present invention.

The example in Fig. 4 shows a wiring groove 2 on the top surface of a square board 1.
They are arranged in a grid pattern, two in each direction. Therefore, the cross-shaped wiring groove 2 is formed by four wires of the same shape and size, which are disposed in a drop-down manner in the substantially L-shaped cross section step portion 4 at the edge of the opening.
It is covered by two cross-shaped cover plates 3.

When three wiring grooves 2 are arranged vertically and two horizontally orthogonally, they are covered with six cross-shaped cover plates 3. In addition, if there are three horizontal and vertical plates, it is covered with nine cross-shaped cover plates 3.
The board 1 may be formed into a rectangular shape as shown in the example of FIG.

When the wiring grooves 2 are provided in the board 1 in a cross-shaped or lattice shape as described above and the grooves 2 are covered with a plurality of cross-shaped cover plates 3, depending on the arrangement spacing of the grooves 2, the wiring grooves 2 may be arranged as shown in the example in Fig. 5. In some cases, two types of cross-shaped cover plates 3A and 3B are used, each having a different length of the cross-shaped extension piece. In this case, the cover plate 3A is 90 degrees and
Can be turned 180 degrees. Also, cover plate 3B is 180
You can change the direction.

The floor panel P is installed directly on the floor of the building.
If it is necessary to secure a space for air conditioning and a space for communication line wiring, pillars of appropriate heights are erected on the floor and floor panels P are arranged on them. Alternatively, a space is created between the panel P and the floor by integrally providing a support on the back side of the floor panel P and laying the support.

[Effect of idea]

The floor panel P of the present invention is installed on the floor as described above, and after passing electric wires through the wiring groove 2, the groove 2 is dropped into the step 4 formed at the opening edge of the groove 2. Since it is covered with the fitted cross-shaped cover plate 3, the cross-shaped cover plate 3 is lighter than the conventional floor panel body and covered with a board of the same shape and size, and there is no directionality in installation. Since the cross-shaped cover plate 3 is covered with a cushioning material, the stepped portion 4 of the groove 2
When fitted, the cross-shaped cover plate 3 conforms well to the board 1 and does not wobble.

Further, since the upper surface of the floor panel P is configured to be flat with the wiring groove 2 covered by the cross-shaped cover plate 3, the floor wiring and finishing of the floor can be performed quickly and easily, resulting in excellent workability.

Furthermore, since the stepped portion 4 formed at the opening edge of the wiring groove 2 has a substantially L-shaped cross section, it is easy to attach and detach the cross-shaped cover plate 3 to the wiring groove 2, and it is possible to quickly respond to changes in the arrangement of load equipment. It is easy to make changes.
