[Prior art]

 The Applicant previously noted that a plurality of blocks, each of which has a substantially flat upper surface, are arranged in a plane to form a gap between adjacent ones capable of accommodating a cable, and hold the 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. For wiring where the finishing material is laid flat as a whole, directly between the blocks and the gap, with a width that does not substantially obstruct the walking and installation of furniture thereover. A floor panel (Japanese Utility Model Laid-Open No. 1-154 731) is proposed.

Further, as an improvement of the above invention, the present applicant rounds the corners of each block at the intersection of required portions of the gap and provides a stepped portion at the upper edge of the rounded corner portion, We have proposed a wiring floor panel in which a cover plate that fits into the stepped portion covers the intersection of the gap (application for Japanese Patent Application No. 4-21306).

[0004]

[Problems to be solved by the device]

 In the publicly known wiring floor panel, when the wiring gaps are provided orthogonally, there is no problem in passing the cables straight through the wiring gaps, but the wiring of the cables is made at the intersection of the wiring gaps. When changing the direction to the left or right, it is difficult to bend the cable because the space at the intersection of the gap is narrow.

In the wiring floor panel of the above-mentioned application, although the above-mentioned drawback of bending the cable at the intersection of the wiring gap is solved, the upper opening at the intersection of the wiring gap has a cover plate. Although it is covered with, the other orthogonal parts and straight parts are laid over the top surface of the wiring floor panel with the open state, so it will be a long time and casters such as chairs and wagons will be left in the gap for wiring. There is a risk of rattling as the product traverses over the top, causing the finishing material to wavy and deform.

The present invention has been proposed in view of the above problems in the conventional wiring floor panel, and facilitates the bending and wiring of the cable with respect to the floor panel, and covers all the upper openings of the wiring gap. It is an object of the present invention to provide a wiring floor panel that covers and improves the workability and handleability of the floor panel.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has a plurality of planarly arranged upper surfaces, each of which has a substantially flat upper surface and forms an orthogonal gap capable of accommodating a cable between adjacent ones. Block and a holding member that holds the gap and connects the plurality of blocks to each other to form a bottom portion of the gap and to provide flexibility to the connected portion. Round the corners of each block at the intersection of the required points of, and set a step on the upper edge of all wiring gaps including the upper edge of the rounded corner, and then fit into the step A grid-like cover plate covers all the gaps between blocks.

The lattice-shaped cover plate preferably has its upper surface slightly lower than the upper surface of the floor panel. In addition, a locking projection for the side surface of the adjacent block may be attached to the back surface of the grid cover plate.

[0009]

[Action]

 When the wiring floor panel of the present invention is laid on the foundation floor, even if there is unevenness (concave and convex) on the foundation floor, the floor panel closely adheres to the unevenness and further covers the wiring gap. The grid-like cover plate is also attached along the upper surface of the floor panel, which is deformed following the unevenness of the foundation floor, and there is almost no step above the wiring gap. Even if a finishing material is put on the upper surface of the floor panel, the finishing material and the grid cover plate are not attached. The grid-shaped cover plate securely stops in the wiring gap via the locking projection.

【Example】

 A configuration of a wiring floor panel according to the present invention will be described with reference to the drawings. One unit of the wiring floor panel 1 is a flat square, and for example, the length of one side is 600 mm or 300 mm, and the thickness is about 30 to 40 mm.

On the upper surface of the floor panel 1, wiring gaps 2 for opening the cables, which are open upward, are formed vertically and horizontally orthogonal to each other, that is, in a grid pattern. The holding member 4 which connects the many blocks 3 divided by the grid-like wiring gap 2 to each other and at the same time forms the bottom of the wiring gap 2 is flexible. The width of the wiring gap 2 is set so that a cable to be wired can be accommodated and arranged in the gap 2.

The wiring floor panel 1 includes a square flexible sheet (a very thin steel or aluminum plate, a hard plastic plate, etc.) and a number of small piece-shaped concrete blocks vertically and horizontally. A plurality of bottomless hollow blocks 3 and holding members 4 which are adhered side by side so as to form a required gap between the blocks, as in the illustrated embodiment, are press-molded or cast using a metal material. (For example, die casting), or one integrally molded by injection molding using a hard plastic material is suitable. In the example of the integral structure, the part of the holding member 4 that connects the bottomless hollow blocks 3 to each other is made flexible by thinning the whole or a part thereof, molding it with a soft material, or making a notch. Have.

Further, in the floor panel 1, a large number of bottomless hollow blocks and holding members are integrally formed by vacuum forming using a thermoplastic plastic sheet material, and the bottomless hollow blocks are filled with lightweight concrete or other filling material. It may be packed and solidified, or a flexible sheet may be stretched on the bottom surface of a bottomless hollow block filled with the lightweight concrete.

A roundness R is attached to a corner of each block 3 at an intersection 5 at a required position of the wiring gap 2 of the floor panel 1. The floor panel 1 of the embodiment shown in FIG. 1 has all the intersections 5 of the wiring gaps 2, the floor panel 1 of the embodiment of FIG. 5 has diagonal portions 5 and the floor of the embodiment of FIG. The panel 1 is one in which each block has a rounded corner R at each intersection 5 located on a diagonal line and on three lines along two lines parallel to both sides of the diagonal line. Shows. In addition, it can be applied to each block at the intersection located on two lines extending in parallel on both sides of the diagonal line.

As shown in FIG. 7, the upper edge of the block 3 that forms the wiring gap 2 of the floor panel 1 (all straight and orthogonal portions of the wiring gap, rounded corners of the orthogonal portion, etc.) A stepped portion 6 is provided at the upper edge portion in FIG. 1, and a grid-like integrated type matching the opening shape of the wiring gap 2 that fits in the stepped portion 6 (FIG. 1, FIG. 4, FIG. 6), a pair of triangles (see FIG. 9) obtained by dividing a rectangle into two along a diagonal line, or a set of four square-shaped lattice cover plates 7 obtained by dividing a rectangle in a cross direction. ing. The lattice-shaped cover plate 7 has a corresponding strength, and for example, a metal plate, a hard plastic plate or the like is used. Since the bars of the lattice are thin, the cover plate 7 can be bent without using a particularly flexible material. Among the orthogonal portions of the wiring gap, the gap of the orthogonal portion where the corners of the block are rounded is wider than the other portions, so the portion of the cover plate 7 that covers the widened portion of the wiring gap 2 is It is desirable to increase the rigidity by increasing the plate thickness on the back side.

The height of the stepped portion 6 and the thickness of the cover plate 7 are adjusted so that the upper surface of the cover plate 7 does not become higher than the upper surface of the floor panel 1 when the lattice-shaped cover plate 7 is dropped into the stepped portion 6. The height is set to keep the entire upper surface of the floor panel 1 substantially flat. If possible, the upper surface of the cover plate 7 is set to be slightly lower than the upper surface of the floor panel 1 as shown in FIG. Further, as shown in FIGS. 10 and 11, a pair of sawtooth-shaped locking projections 8A (FIG. 10) elastically fitted to the opposite side surfaces of the wiring gap 2 at appropriate places on the back surface of the cover plate 7, or the wiring gap. It is advisable to provide a lotus-shaped locking projection 8B (FIG. 11) which is elastically fitted at the same time on the two opposite side surfaces. The sawtooth-shaped locking projection 8A is integrally formed with the cover plate 7, and the lotus flower-shaped locking projection 8B is made of plastic. The molded separately from the cover plate 7 is adhesively fixed to the back surface of the cover plate 7.

The wiring floor panel 1 of the present invention is laid on the floor with the wiring gap 2 facing up. An adhesive or mortar is used to fix it to the floor. By laying the wiring floor panels 1, a grid-shaped wiring gap is formed on the entire floor by the continuous wiring gaps 2. In FIGS. 1, 2, and 3, C1 and C2 are cables linearly housed in two parallel gaps 2, C3 is a cable accommodated in a gap 2 orthogonal to the cables C1 and C2, and C4 is the above cable. A cable that is bent by bending to the right at a gap intersection 5 where the space is widened by rounding R at the corner of the block 3 from the gap 2 that is parallel to the gap 2 that houses C1 and C2. C5 is the cable The cable is accommodated by bending to the left at a gap intersection 5 having a wider space from a gap 2 on the opposite side of the cable C4 which is parallel to the gap 2 which accommodates C1 and C2. Where the cables are orthogonal to each other, if necessary, a separator may be inserted between the cables to avoid contact between the cables.

After the cables C1 and the like are accommodated and arranged in the grid-shaped wiring gaps 2 formed on the floor as described above, the grid-shaped cover plate 7 is attached to the upper edge step portion 6 of the block 3 and The upper surface opening of the wiring gap 2 is closed. Then, a finishing material 9 such as a carpet tile or a carpet is attached to the upper surface of the flat wiring floor panel 1 as shown in FIG. 8 if necessary.

When the finishing material 9 is attached, a pressure-sensitive adhesive (peel-up bond, etc.) is used so that the finishing material 8 can be easily peeled off at the time of adding or relocating the wiring later, but the pressure-sensitive adhesive is used for the wiring floor. If the adhesive adheres to the cover plate 7 when it is applied to the upper surface of the panel 1, the finish material 9 and the cover plate 7 stick to each other, and when the finish material 9 is peeled off, the cover plate 7 is also peeled off. Is bad and difficult to handle. It should be noted that the adhesive does not stick to the cover plate 7 when it is applied, but such application work is extremely troublesome and reduces work efficiency.

Therefore, if the upper surface of the cover plate 7 is made slightly lower than the upper surface of the wiring floor panel 1 as shown in FIG. 8 described above, the pressure sensitive adhesive is applied to the upper surface of the wiring floor panel 1. At this time, the adhesive does not adhere to the cover plate 7, and even if it does, there is a gap S between the cover 9 and the finishing material 9 attached on the wiring floor panel 1. 7 does not stick.

Further, as described with reference to FIGS. 10 and 11, when the cover plate 7 is provided with the locking projection 8 A or 8 B for the wiring gap 2, the cover 2 is covered with an opening on the upper surface of the wiring gap 2. When the cover plate 7 is attached, the locking projections 8A or 8B are elastically or frictionally locked to the side surfaces of the wiring gap 2 to prevent the cover plate 7 from rising and coming off.

[Effect of device]

 The present invention has a plurality of blocks, each of which has a substantially flat upper surface, and which is arranged in a plane with orthogonal gaps between adjacent ones capable of accommodating cables and holding the gaps. Then, the plurality of blocks are connected to each other to form a bottom portion of the gap, and in a wiring floor panel having a holding member that gives flexibility to the connection portion, at a crossing portion of a required portion of the gap. In addition to rounding the corners of each block, stepped portions are provided on the upper edges of all wiring gaps including the upper edge of the rounded corners, and a grid-like cover plate that fits in the stepped portion Since all the gaps between the blocks are covered with, the space at the intersection of the wiring gap becomes wide, and it is easy to bend and wire the cable to the left and right at the intersection. The grid-like cover plate is installed following the upper surface of the wiring floor panel, and the steps above the wiring gap are almost eliminated, so walking and fixtures are installed, or casters such as chairs and wagons are crossed. There is no obstacle to movement.

Further, since the upper surface of the grid-like cover plate covering the wiring gap is slightly lower than the upper surface of the wiring floor panel, there is no need to attach an adhesive for attaching the finishing material to the cover plate. A gap is created between the attached finishing material and the cover plate to prevent adhesion between the finishing material and the cover plate, and when the finishing material is peeled off for additional wiring, relocation, or inspection, the cover plate sticks to the finishing material. To facilitate subsequent work.

On the back surface of the grid-like cover plate that covers the wiring gap, the locking projections are provided on the side surfaces of the adjacent blocks, so that the grid-like cover plate can be securely attached to the upper opening of the wiring gap. This has the effect of preventing the lattice-shaped cover plate from rising.
