Description

TECHNICAL FIELD The present invention relates to a floor panel, and particularly to a wiring floor panel suitable for electrical wiring.

BACKGROUND ART In an electric equipment room such as an electronic computer room or an office automation room, cables such as a power supply line, a signal line, and a communication line to each device are usually laid on the floor. Nowadays, even in an ordinary office, there are many electric devices, and their connecting lines are often laid on the floor.

For this floor wiring, the applicant has previously proposed a floor panel device suitable for free wiring (see Japanese Patent Laid-Open No. 62-284854). This floor panel device has a plurality of blocks arranged in a plane, and each block is connected with a flexible sheet so as to define a predetermined wiring groove between the blocks. The wiring groove uses the side surface of the adjacent block as a side wall,
The flexible sheet has a corner-shaped U-shape with the top as the bottom and the top as the opening. When constructing a floor panel, the upper opening is covered with a rigid cover flat plate, and a finishing material is put on the upper flat plate to finish the entire floor into a flat floor surface.

This conventional floor panel device, even if there is some unevenness on the construction floor of the building, fits well on the unevenness of the floor due to the bending effect of the flexible sheet, leveling work and flattening work etc. There is a feature that makes finishing work unnecessary. However, there are problems with the following three points.

First, in the wiring work, the work of attaching and removing the cover plate is relatively complicated, and it takes time to access the wiring groove. This is because the upper opening of the wiring groove is covered with a cover plate, and a finishing material such as carpet tile is laid on the cover plate. Further, the ratio of the cover plate to the entire floor panel device is relatively large, which raises the device price. In addition, a peripheral panel such as the wall of the room to be constructed requires a dedicated panel other than this. Further, in a place where floor wiring is unnecessary, such as a furniture installation location, the floor panel device having the above-described structure does not always have sufficient load resistance, and it was economical to use a normal floor panel.

Object The present invention solves the above-mentioned drawbacks of the prior art, and an object of the present invention is to provide a wiring floor panel having improved workability and handleability against a floor surface of a building.

DISCLOSURE OF THE INVENTION According to the present invention, a plurality of blocks are flexibly connected to each other, and a wiring groove having a width that does not hinder walking or installation of furniture is formed between adjacent blocks. It is allowed to lay the finishing material directly on the flat surface as a whole.

The wiring floor panel according to the present invention has a plurality of blocks, each of which has a substantially flat upper surface and is arranged in a plane to form a gap between adjacent ones capable of accommodating a cable, and a gap. A plurality of blocks are connected to each other to form a bottom portion of the gap, and a holding member that imparts flexibility to the connection portion is provided, and the gap is provided between adjacent blocks of the plurality of blocks. Is formed with a width that does not substantially interfere with the walking and installation of furniture, so that the finishing material is laid flat as a whole directly on the plurality of blocks and gaps.

Description of Embodiments An embodiment of a wiring floor panel according to the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIGS. 1A and 1B, a wiring floor panel 10 according to one embodiment of the present invention basically comprises a sheet 12 of a generally flat flexible material and one major surface 14 thereof. And a plurality of blocks 16 arranged in the. In this embodiment, the block 16 is a rectangular parallelepiped as a whole, and the shape viewed from above in the figure is a rectangle such as a square or a rectangle. Therefore, the overall shape of the flexible sheet 12 may be rectangular. Thus, the floor panel 10 having a flat rectangular shape as a whole is formed. A floor-wiring floor is formed by laying a plurality of floor panels 10 on a floor surface of a building.

For the flexible sheet 12, for example, synthetic resin or rubber is advantageously applied. Alternatively, a metal having a very small plate thickness, such as steel or aluminum, and a relatively hard material such as a hard synthetic resin may be used. For the block 16, for example, lightweight concrete in which mortar cement is mixed with sawdust, air bubbles, perlite, or the like, hard synthetic resin, particle board or wood is advantageously used. Block 16
The inside may be dense, but may be hollow depending on the material.

As can be seen in Figure 1B, the block is a rectangular solid as a whole.
16 is the upper surface 14 of the flexible sheet 12 whose lower surface in FIG.
It is fixed to this by sticking it on with an adhesive. When the block 16 and the sheet 12 are made of the same material, such as a hard synthetic resin, they may be integrally formed.

A wiring groove 20 for wiring a cable 18 such as a power supply line to an electric device, a signal line, or a communication line is formed between two blocks 16 adjacent to each other. In this embodiment, these wiring grooves 20 are formed in a straight shape over a plurality of blocks 16 and are orthogonal to each other so as to define a more square shape.
The wiring groove 20 uses the side surface 28 of the adjacent block 16 as a side wall,
The flexible sheet 12 has a corner-shaped U-shape with the upper portion 14 of the upper surface 14 serving as the bottom and the upper portion opened.

A flat finishing material 50 such as a carpet tile is laid on a plurality of floor panels 10 laid on the floor surface of a building. The width of the wiring groove 20 is basically so small that it does not hinder walking on the wiring groove 20 and a part of the finishing material 50 does not fall therein, and the cable 18 can be sufficiently accommodated therein. Dimensions are advantageous. More specifically,
For example, the heel of the thinnest shoe, or the thinnest leg of a furniture such as a bookcase that does not require wiring, presses the finishing material 50 from above, and the portion does not fall into the wiring groove 20. So that the wiring groove 20 is formed by
Blocks 16 are arranged.

Such a floor panel 10 may be laid directly on the floor of a building, for example, a bare concrete floor, regardless of the presence or type of the cable 18 to be laid. The spread floor panel 10 may be fixed to the floor of the building by a fixing means such as an adhesive or mortar. In this way, the floor panel 10 is arranged so that the wiring grooves 20 are continuously formed in a net shape over the plurality of floor panels 10. In that case, even if the floor is made of concrete, the floor panel 10 flexes freely along the unevenness, that is, the unevenness of the floor surface, so that the floor panel 10 can fit on the floor surface and adhere thereto.

The floor panel 10 includes a flexible sheet 12 and a portion 26 of the wiring groove 20.
Can be cut into a suitable shape. Floor panel 10
The simple substance of 1 is usually formed with the same predetermined size. Therefore, depending on the size and shape of the room to be laid, a space may be created between the floor panels 10 or between the floor panel 10 and the room wall. In such a case, the flexible sheet 12 of the floor panel 10 can be cut into an appropriate shape by the wiring groove 20 located at a position that approximately fits the gap, and this can be used to fill the gap. Therefore, regardless of the presence or absence of wiring, only one type of floor panel 10 is used for the floor surface to be laid, and other panels may not be used.

Floor panel 10 also includes block 16 as shown in FIG. 1A.
Can be cut off at the portion of the wiring groove 20. The existing portion of the excised block 16 forms a concave portion 22.
For example, wiring equipment such as an outlet or a telephone terminal block can be arranged and stored in the 22. A cover 52 that covers the wiring device and fills the recess 22 may be housed in the recess 22. The cover 52 is, for example, a block as a whole.
It has an outer shape of a rectangular parallelepiped substantially corresponding to 16, and as can be seen from the figure, this embodiment has a pair of legs 54 and has a substantially U-shaped cross section. The cover 52 is recessed so that its legs 54 are supported on the upper surface 14 of the flexible sheet 12.
Fits in 22. This causes the top surface 56 of the cover 52 to substantially coincide in height with the top surface 24 of the block 16 and thus the finish 50 to be laid flat as a whole.

In this embodiment, the flexible sheet 12 is arranged below the block 16. In another embodiment of the present invention, the flexible sheet 12 includes a top surface 24 and side surfaces 28 of each block 16 as shown in FIG. 1C.
May be covered so that each block 16 is held by the flexible sheet 12. Top 2 of block 16
The 4 and / or the side surface 28 may be attached to the flexible sheet 12 with an adhesive. In addition, in the following figures, 1A
Elements similar to those shown in the figures and FIG. 1B are designated by the same reference numerals. Alternatively, as shown in FIG. 1D, the entire upper and lower surfaces and side surfaces of the block 16 may be covered with the flexible sheet 12, and the block 16 may be held by the flexible sheet 12.

2A and 2B show another embodiment of the present invention in that the planar shape of the block 16 is an equilateral triangle, and that the block 16 is hollow and the lower surface is open. This is different from the first embodiment. Since the block 16 is an equilateral triangle, the planar shape of the entire floor panel 10 is an equilateral triangle in this embodiment.

The block 16 of this embodiment has a top surface 24 and sidewalls 28 defined by a relatively rigid retention material 30, which is integrally molded with the bottom 26 of the wiring trench 20. The holding material 30 is made of, for example, aluminum die cast, or a non-combustible or flame-retardant relatively hard synthetic resin, and the block 16 and the wiring groove 20 are integrally formed by injection molding, for example. The bottom portion of the wiring groove 20, that is, the connection portion 26 that connects the adjacent blocks 16 is formed to be thinner than the material thickness of the upper surface 24 or the side surface 28 of the block 16, which is not clearly shown in the figure, and thereby the floor panel 10 is formed. The overall flexibility is given to conform to the unevenness of the construction floor. The thin portion may be formed over the entire bottom surface 26 of the wiring groove 20 or may be partially formed in a part thereof.

The planar shape of the block 16 may be arbitrary. For example, it may have a hexagonal shape as in another embodiment of the present invention shown in FIGS. 3A and 3B. In this case, the planar shape of the entire floor panel 10 may be rectangular. Also, as shown in FIGS. 4A and 4B, the trapezoid is trapezoidal in other embodiments. In this case, the entire floor panel 10 has a square planar shape. Generally, there is a relationship between the planar shape of the floor panel 10 and the planar shape of the block 16 as shown in Table I. Normally, the plan shape of a room in a building is often rectangular. Therefore, even if the floor panel 10 has a planar shape other than a rectangular shape, it may have a shape such that, when it is applied to the floor surface, the entire outer peripheral shape can finally form a rectangular shape by cutting. Therefore, it may be a general triangle other than the equilateral triangle and the isosceles right triangle.

For example, as shown in FIGS. 5A and 5B, block 16
A concave decorative joint 32 may be formed on the upper surface 24 of the. The joint 32 may have a cross shape as in the same embodiment. This is because, for example, if the area of the top surface 24 is
It is advantageous to reinforce the mechanical strength of 16. In addition, if the joint 32 is enlarged to some extent, a relatively thin cable such as a telephone line can be accommodated in the joint 32. The joint 32 is particularly advantageous when the block 16 is hollow.

Further, as shown in FIGS. 6A and 6B, the joint 32 may be deepened to a depth substantially the same as the bottom surface 26 of the wiring groove 20. In this example, it may be considered that two kinds of wiring grooves 20 in the embodiment shown in FIG. 1A are formed. In this embodiment, a small protrusion 34 is formed on the upper surface 24 of the block 16 to prevent lateral displacement of the finishing material 50 after construction. Of course, a plurality of protrusions 34 may be provided on one upper surface 24.

It is needless to say that the embodiments shown in FIG. 1C and subsequent figures also have the structural and construction features already described for the embodiments shown in FIGS. 1A and 1B.

As described above, according to the present invention, a plurality of blocks are flexibly connected to each other and a wiring groove is formed between adjacent blocks with a width that does not hinder walking or installation of furniture. It allows the finish to be laid substantially flat directly on top. Therefore, the floor panel flexes freely along the unevenness of the floor surface and conforms to the floor surface to adhere to it. Further, by preparing only one kind of floor panel, it is possible to cope with any flat shape of the laid floor surface, and the construction can be performed regardless of necessity of wiring. further,
Since the finishing material is laid directly on the floor panel, it is easy to access the wiring groove during construction or when changing the wiring, simplifying the man-hours required and eliminating the need for a cover plate as in the past. Is. Therefore, the cost of the entire device is reduced.
