Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a wiring flooring material, and more particularly to a wiring flooring material in which blocks are spread over the upper surface of a flexible sheet.

[Conventional technology]

With the recent trend toward office automation, there is an increasing need for so-called underfloor wiring, in which the floors of offices and the like are made into double floors and cables are routed within this floor. Hitherto, as methods for forming such a free access floor, a raised floor whose height can be adjusted and a free-standing floor in which small blocks are laid out in a square sheet shape are known.

Examples of these raised floors for underfloor wiring will be described below with reference to the drawings. FIG. 10 is a perspective view showing the structure of an example of a raised raised free access floor, in which support legs 2 having fixing flanges on the upper and lower surfaces of the building are arranged in a rectangular shape to match the size of the panel 1. Install and fix at intervals, set the metal or plastic panels 1 at the four corners by inserting gaskets 5, fix the four corners to the upper flanges of the support legs 2 with corner screws 3, and place them on top. It is constructed by laying carpet tiles 4. The cables are then laid under the floating floor as described above.

On the other hand, as an example of a flooring type floor, as shown in the exploded perspective view of FIG. 11, a rectangular sheet floor 6 is laid directly on the subfloor surface of a building. A wiring cable conduit 7 for wiring the cable 8 is provided in advance on these seat floors 6. After wiring the cables 8, the adjacent seat floors 6 are interconnected with a separate bridge 9, and an outlet fixing fitting 10 and a cross cover 11 are placed on the wiring cable installation conduit 7 as necessary. A raised floor is constructed by placing a carpet tile 12 on top. In addition, the code|symbol 13 is an outlet installed on the floor. Examples of such free access floors include those shown in Japanese Utility Model Application Publications No. 60-164537 and No. 62-165330.

[Problem to be solved by the invention] The former type of raised raised free access floor has excellent aesthetics, is relatively easy to adjust the floor level, and has the advantage of being able to withstand heavy objects, but on the other hand, it is heavy and has difficulty in construction. There are problems such as being bad and expensive. On the other hand, the latter type of free-standing floor has the advantage of being lighter and easier to construct than the above-mentioned raised free access floor, but there are restrictions on the piping route, and it is difficult to embed a feed-in box or other box. In addition, there are still problems that need to be solved in terms of construction, such as the need for special sheet pieces with blocks, and the transportation of the block sheet pieces and the positioning of the laying 1 (sheet misalignment).

The present invention has been made in view of the above points, and an object of the present invention is to provide a novel flooring material for wiring, which eliminates the drawbacks of the above-mentioned prior art and can significantly improve workability, workability, transportability, etc. The purpose is to

[Means for Solving the Problems] The present invention has a large number of blocks removably arranged in a lattice pattern on the upper surface of a flexible sheet laid on a subfloor surface, and a sheet on a thin film is placed on top of these blocks. This flooring material for wiring is characterized in that it is constructed so that it can be wrapped or folded into a roll by adhering it to the flexible sheet in a lattice pattern by covering it with vacuum and vacuuming it.

[Example] Hereinafter, the present invention will be described in detail based on the drawings. 1st
FIG. 2 is a perspective view and a side view showing the appearance of one embodiment of the wiring flooring material for a free-standing raised floor according to the present invention. A large number of cubic or rectangular parallelepiped blocks 22 each having a height of 50 mm are arranged on the sheet 21 in a grid pattern.

The flexible sheet 21 is made of a thick sheet of rubber or flexible plastic, and the block 22 is made of hollow aluminum die-casting, lightweight concrete, non-flammable building materials, or flame-retardant engineering material. It is made of plastic or the like into a block shape. These blocks 22 are then covered with a transparent thin film sheet 24 from above as shown in FIG. Both sides of the flexible sheet 21 and the lattice-shaped portion between the blocks 22 are sealed by heat welding or adhesive to prevent the blocks 22 from shifting,
This wiring floor material 2o is configured to be fixed so as not to fall off.

Therefore, when storing and transporting, the block 22 is rolled up into a roll with the block 22 facing outward, as shown in FIG. 2, so that the block 22 is not bulky.

Moreover, a blank space where the blocks 22 are removed can be formed vertically and horizontally between the arrays of blocks 22 on the flexible sheet 21, and a piping path 23 for laying a cable can be formed in advance in this space.

As shown in FIG. 4(A), the flexible sheet 21, which is the base of the wiring floor material 20 formed in this way, has incisions 2 along the grid-like mesh of the blocks 22 as needed.
5, any shape.

The block 22 is formed so that it can be removed to any size, so that it can be easily modified to match the shape or corner of the room where the cable is installed, or to easily process the piping route.

Further, as shown in FIG. 4(B), the block 22 has a protrusion 22a formed at the bottom, a recess formed by cutting out the peripheral edge 22b of the upper surface, and a protrusion 22 in the center that supports the decorative material.
It is convenient to form 2c so that the 6 wiring cables can be drawn out from any position, and
If the bottom protrusion 22a is fitted into a hole provided in the flexible sheet 21 as shown in cross section in FIG. 3(B), the block 22 can be held even more firmly.

Next, using the wiring floor material 20 formed in this way,
An example of forming a raised floor will be described with reference to the plan view of FIG. 9.

The flooring material 20 for wiring is spread out and laid by leveling the subfloor surface of the building. At this time, the flooring material 20 is transported with the block 22 side rolled outward as shown in FIG. Lay them in the same way, and if necessary, lay them adjacent to each other. At this time, remove unnecessary or unnecessary blocks 22 in the corners and sides of the room by cutting into the notches 25 with a cutter, etc. Also, remove the blocks 22 in the part where the cable bow box will be installed in the same way, and The flooring material 20 for wiring is fixed on the lower surface of the flexible sheet 21 with an adhesive or locking screws at multiple points on the underfloor surface. Further, the cable is laid through the cable piping path 23 from where the cable lead-in box is located. As shown in FIG. 9, a pipe cover 27 having the same thickness as the protrusion 22c of the block 22 is placed on top of the pipe line 23, extending over the recess 22b on the upper surface of the adjacent block 22. A cross-shaped lid 28 having the same thickness as the protrusion 22c of the protrusion 22 is placed over the crossroads 23 and fixed. This conduit cover 27 is provided with holes or grooves 26 at necessary locations for installing the cable, and the installed cable is inserted through it and pulled out onto the floor. Lay decorative materials such as carpet tiles on the block 22,
A hole is drilled in the required tile carpet, the cable is pulled out and stretched, and a concette is attached and fixed as necessary to the raised cable part. Note that the wiring cable can be set up through the recess 22b on the block 22 at any position.

Next, a second example of the wiring floor material will be described. In the above example, the sheet is formed into a roll for convenient storage and transportation, but in this example, the flexible sheet is folded into three or two. That is, as shown in FIG. 5(A), a folding slit 29 is formed in the long flexible sheet 21a at a certain length in the width direction.

The rest of the structure is the same as that of the first embodiment. Therefore, in this example, it is convenient to store and transport the flexible sheet 21a by folding it into three and stacking them on top of each other.

Also, as a modification of this example, a sectional view is shown in FIG.
As shown in the plan view in the figure, the flexible sheet 21b is formed with folding slits 29 in the width direction and folded in two, and the folding slits 21b are bent into each other as shown in FIG. 5(C), for example. By folding it up, it is convenient for storage and transportation.

Next, a third embodiment of the present invention will be described based on FIG. The wiring floor material 30 of this example basically has almost the same structure as that of the first example, but the only difference is that the flexible sheet has a locking mechanism on the side to prevent slippage. ing. That is, the flexible sheet 21c serving as the base has a concave groove 31 that widens inward on one side, and a protrusion 32 that widens at the tip that engages with the concave groove 31 on the other side.
are formed at regular intervals. Therefore, when laying these flooring materials 30, by engaging the projections 32 with the grooves 31 of the adjacent sheets 21c, the flooring materials 30 can be laid without shifting.

In addition, although the above example was explained with a locking mechanism provided on the side surface of the flexible sheet, the flexible sheet is made into a rectangular block of a certain size, and locking mechanisms are provided on all four end surfaces. In this case, the flooring material for wiring can be laid out in square blocks of a certain size in a manner that connects them together, and further work is required. It becomes a floor material for wiring with good properties.

Next, a fourth embodiment of the present invention will be described based on FIG. The above-mentioned first to third embodiments are as follows.

The cable piping path 23 is formed by removing the block 22, but in this example, the required cable trunk line corresponding to, for example, two blocks and the necessary cable main line corresponding to, for example, one block are formed on the flexible sheet serving as the base in advance. They differ in that they are wiring flooring materials with pre-formed cable piping paths. That is, this wiring floor material 40 is constructed by providing, for example, a main line 33 and a piping path 34 on a long flexible sheet 21d, and laying blocks 22 on the other parts. By creating several basic patterns for trunk lines and piping routes and combining them as needed, users can assemble the piping route they need. Furthermore, construction is easier.

[Effects of the Invention] As explained above, the wiring flooring material of the present invention is constructed by arranging blocks in a grid pattern on a flexible sheet, and has dramatically improved transportation, storage, and workability. Become something. Furthermore, since the blocks can be freely attached and detached, it is easy to increase or decrease the number of cable conduits after installation, and flexible wiring designs are possible at any time. Furthermore, since the block is sealed with a thin film and a flexible sheet, no powder is generated even if the block is made of lightweight concrete, making it environmentally friendly and sanitary.
