Description of the Related Art Recently, against the background of remarkable technological innovation in electronics, efforts are being made to develop a local area network that connects a plurality of office automation devices to each other. This type of local area network is, for example, between a plurality of workstations, large-capacity files, printers, etc., through an information transmission cable such as a coaxial cable or an optical fiber cable, and is high speed such as 10 Mbit. It is for data communication.

By the way, this type of local area network is constructed by arranging a trunk cable such as a coaxial cable or an optical fiber cable vertically and horizontally in an office or the like, and connecting office automation equipment to the trunk cable. . At this time, in order to prevent accidents such as cable disconnection when changing the layout of the office automation equipment, arrange electrical components such as couplers, transceivers, and modems in the vicinity of the main cable, and derive the lead-in cable from these electrical components. The office automation equipment is connected to the main cable.

However, when constructing a network in this way, it is necessary to install signal cables and electrical components, and to increase the power capacity of office automation equipment and power outlets.

Therefore, there is a strong demand for the development of a network construction method capable of easily performing the laying / expansion work and sufficiently dealing with the layout change after the laying work.

In order to meet such a demand, a free access floor is conventionally used in a computer room or the like. This free access floor is 30
~ 40cm square floor panel from the floor (slab) 1
It is intended to float about 5 to 30 cm and to lay a signal cable, a power cable or the like between the floor panel and the slab.

However, when cables are pulled out from the signal cable or power cable laid between the floor panel and the slab onto the floor panel and connected to the office automation equipment, conventionally, each time the floor panel is connected to the office automation equipment.・ The fact is that the panel has holes to draw out the cable. Therefore, there was a problem that the construction was extremely difficult.

Further, when the layout of the office automation equipment is changed, it is necessary to re-open the above-mentioned hole for pulling out the cable in accordance with the change of the layout. On the other hand, it is necessary to prepare a blind plate or the like for the hole for pulling out the cable that is no longer needed and close it each time. Therefore, the construction is very large,
I could not easily deal with layout changes.

[0009]

In the floor panel constituting the conventional free access floor as described above, a signal cable, a power cable or the like is pulled out each time depending on the office layout. There is a problem that it is necessary to provide holes and it is not possible to easily deal with the layout change.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a notched portion having a locking portion having a predetermined step on at least one side of a panel plate. With the basic panel board unit that it has, it is possible to facilitate the wiring of network cables and power cables that connect to office automation equipment.
It is an object of the present invention to provide a highly practical basic panel board unit capable of facilitating extraction of the cable to the floor surface and sufficiently dealing with layout changes and the like, and a floor surface construction method using the basic panel board unit.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing a configuration of an embodiment of a basic panel board unit of the present invention, and FIG. 2 is a view showing a side structure thereof.

The panel plate (top plate) 1 is composed of a plate body 2 and a surface material 3 attached to the surface thereof. This panel board 1 is, for example, 45 cm × 45 cm in consideration of workability and transportability.
Is set to the size of. Although the plate body 2 will be described in detail later, it is configured by appropriately using various materials such as a calcium silicate plate, a particle board, a honeycomb structure plate, and a composite cement material. At this time, the load resistance required for the top plate 1,
It goes without saying that the constituent material is selected in consideration of weight, thickness, insulation, fire resistance, economy and the like.

As the surface material 3, so-called vinyl tile, carpet, jutan, or the like is used, which may be selected according to its use and purpose.
On the other hand, reference numeral 4 in the drawing denotes a lower surface plate which is paired with the upper surface plate 1,
For example, it is composed of an insulating plate. The lower surface plate 4 is provided with a plurality of holes 5 for fixing electrical components, for example, in a matrix form, if necessary. The lower surface plate 4 separates a space for arranging signal cables and electric components forming a network from a space for arranging power system cables as described later.

Thus, the panel plate 1 and the lower plate 4 have four columns 6 (6a, 6b,
6c, 6d) and are supported in parallel with a predetermined gap. The pillars 6 fix the four corners of the lower plate 4, respectively, and the pedestal 7 is provided on the upper end surface of a predetermined height. The four corners of the panel plate 1 are fixed on the pedestal 7, and between the panel plate 1 and the lower surface plate 4 there is a predetermined gap in which signal cables and electrical components can be arranged, for example, an upper space having a height of 35 mm. It is formed.

On the lower side of the lower plate 4 of the pillar 6,
A leg portion 8 is provided which is a screw mechanism that can move forward and backward by rotation. The amount of protrusion of the leg portion 8 is adjusted so that the leg portion 8 protrudes below the lower surface plate 4 and contacts the floor surface (slab) 9.

In this way, each pillar 6 is connected to the panel plate 1 described above.
And the lower surface plate 4 are respectively supported and provided on the floor surface 9. At this time, as shown in FIG. 2, a lower void having an average height of about 15 mm is formed between the lower plate 4 and the floor 9 so that a power system cable or the like can be arranged.

The panel plate 1 and the column 6 are joined and fixed by, for example, a screw 10. This specific structural example will be described later. In addition, like this, the panel board 1
The pillar 6 that supports the lower plate 4 is made of, for example, a casting of iron, aluminum, or the like, or a ceramic having excellent insulating properties and economical efficiency, and further, a synthetic resin or the like.

The floor panel thus constructed is laid on the floor surface 9 of the office by abutting the ends of the panel plates 1 of the plurality of floor panels with each other as shown in FIG. 3, for example. At this time, a cable take-out jig 11 is provided at the end butting portion of the panel plate 1 as required. The cable take-out jig 11 and the like are attached by being fitted into the communicating portion by utilizing a communicating portion such as a cut recess provided in an end portion of the panel plate 1 as described later.

A network trunk cable 12, such as an optical fiber or a coaxial cable, is laid in the upper space formed between the panel plate 1 and the lower plate 4, and if necessary, a coupler or transceiver, Electrical components such as modem 13
Are attached using the holes 5 provided in the lower plate 4. Then, the lead-in cable 14 is taken out from the electrical component 13 through the cable take-out jig 11 to the upper surface of the panel board 1, that is, the floor surface, and is connected to a predetermined office automation device.

In the lower space formed between the lower plate 4 and the floor 9, a power system cable 15 is laid separately from the signal cable 12 and the like. And this power system cable
A power outlet or the like drawn out from 15 is provided on the lower surface plate 4 or fitted into a communicating portion of the panel plate 1 or the like.

The extraction of signal lines from the signal cable and electrical equipment laid between the panel board 1 and the floor 9 and the extraction of electric power from the power cable are performed as follows. Be seen.

That is, as shown in FIG.
As shown in FIG. 3, a cutout portion 41 having a locking portion 48 having a predetermined step (recess) is provided as a communication portion with respect to the upper surface of the panel plate 1. When the basic panel board units are spread, the communication section forms a notch space by the adjacent basic panel board units. Then, the engaging recesses 49, 50 formed on the side surface of the cable take-out jig 42 (11) or the power outlet 43 are fitted into the engaging portion 48 of the cutout 41, for example, as shown in FIGS. 5 (a) and 5 (b). It is configured to When it is not necessary to attach these outlets, for example, a blind plate 44 as shown in FIG. 5C is attached to the cut portion 41.

Here, the cable take-out jig 42 is composed of, for example, two members 42a and 42b which divide the cable insertion hole 45 into two parts, and the signal cable 12 and the like are sandwiched by the members 42a and 42b. The engaging recess 49 formed on the lower side surface is fitted into the cutout 41. The cable take-out jig 42 is adapted to protrude from the upper surface of the panel plate 1 by a predetermined height to be attached to the cutout portion 41. This allows water from the insertion hole 45 when cleaning the floor or the like. The invasion of is prevented.

Further, the power outlet 43 is configured to be fitted into the cut portion 41 by the engaging recess 50 on the lower side surface so that the outlet terminal surface is exposed from the upper surface of the panel plate 1.

Utilizing a communication portion such as that shown in the recessed notch portion 41, the signal cable can be taken out from an arbitrary position on the floor in the office in units of floor panels,
The power supply can be easily taken out.

Regarding the power supply to the electric component 13 provided in the upper space formed between the lower plate 4 and the panel plate 1 described above, for example, as shown in FIG. A recess 46 may be provided and a power outlet 47 as shown in FIG. 7 may be attached to the recess 46. By doing so, the mounting position of the electrical component 13 can be changed relatively easily.

According to the panel having such a structure, the cables are arranged in the space formed between the panel plate 1 and the floor surface 9, and the communication portion provided in the panel 1 can be easily and easily passed through. Cables can be taken out from any position on the floor as a unit.

That is, in the work of laying the panel board, the outlets may be fitted into the panel board at the place where the outlets are desired to be attached to the step locking portion of the notch of the panel board. Safety is ensured because the blind plate is attached to the step locking part of the panel plate that does not require outlets.

Therefore, by laying a plurality of such basic panel board units of the present invention on the floor, the safety is excellent and the wiring of the power cable and the signal cable required for the OA floor is performed under the floor, and the outlet is provided. It is possible to place the cable takeout parts, etc. on the panel board at the desired place. Also, if it is necessary to move the positions of outlets and cable outlet parts due to layout changes, it is easy to remove the blind plate attached to the panel board at the changed location and fit the outlets and cable outlet parts. It is possible to deal with layout changes.

Moreover, since the cut portion has a size to which either a component such as an outlet or a blind plate can be attached, when the panel board is laid or the layout is changed, the cut portion may be touched with a hand, or Since the hand can be operated in the space formed in the cut portion of the adjacent panel plate, the work can be performed safely and easily without pinching the hand.

Further, according to the structure of the above-described embodiment, the signal system and the power system can be separately installed in the upper space and the lower space separated by the lower plate 4.
In addition, it is possible to easily perform the installation by satisfying various restrictions in laws and regulations. Therefore, the network can be flexibly constructed.

Since the signal system and the power system can be separately laid in this manner, the work of laying the signal system, which is generally composed of a weak current circuit, should be outsourced to a specialist technician stipulated by law. Instead, the office worker can easily perform the work according to the layout specifications.

Further, as described above, since the signal system and the power system can be separated by the lower surface plate 4, unless the signal system cable or the electrical equipment has a shield structure or grounding work. There will be no legal restrictions such as not becoming. As a result, it is possible to greatly simplify the signal system and reduce its cost.

Further, since the electrical equipment 13 and the like can be easily fixed to the lower surface plate 4, it is possible to effectively prevent an unreasonable force from being applied to the electrical equipment 13 during the laying work, and The reliability can be maintained sufficiently high. Furthermore, the work involved in changing the layout of the network can be easily carried out by simply removing the panel board 1. Moreover, since the cable can be taken out from any position on a floor panel basis, it is possible to sufficiently cope with the layout change accompanying the movement of the office automation equipment.

Secondly, since all the cables and electrical components can be housed in the floor panel, the aesthetic appearance of the office is excellent, and there is no risk of accidents such as hooking the cables. .

As mentioned above, the signal cable laying work can be easily performed as described above, but the laying work of the electric power cable also requires the work of a specialist technician according to the law, and thus It becomes a factor of hindering the layout change. Therefore, a plurality of power outlets may be provided in advance on the lower surface plate 4 at important points during initial installation of the power system cable. By doing so, it is not necessary to perform power system work when changing the layout of the network, and it is possible to eliminate the above-mentioned factors that hinder the change of the network.

The legs 8 provided on the columns 6 are for adjusting the height of the panel plate 1 with respect to the floor surface 9 to form a uniform floor surface. Needless to say, it is possible to lower the height of each leg portion 8 sufficiently to lower the floor surface front body when the above construction is sufficiently performed. Depending on the specifications of the office, it is of course possible to omit the bottom plate 4 and install only the panel plate 1. Further, it is of course possible to further provide a pillar at the central portion of the panel to strengthen the support structure thereof, and it is also possible to provide the pillar at four corners of the panel board 1.

By the way, it is desirable that the panel plate 1, the bottom plate 4 and the columns 6 which constitute the floor panel having the above-mentioned structure are specifically constructed as follows. Figure 8 (a) (b)
9 (a) and 9 (b) show examples of the structure of the panel board 1. FIG. 9 (a) is a partially cutaway plan view, and FIG. 9 (b) is a longitudinal sectional view thereof.

Generally, the load strength of an office is 300
kg / sqm, 10 like a computer room
A load strength of more than 00 kg / square meter is not required. On the other hand, there is a strong demand for lightness, fire resistance, insulation, a thin floor material for keeping the floor height low and securing a wide floor space, and economical efficiency. Therefore, in order to construct the panel board 1, it is necessary to fully consider these requirements.

8 (a) and 8 (b), a honeycomb structure 21 made of asbestos, aluminum or the like is sandwiched by a synthetic resin such as Bakelite or an aluminum plate 22, and this is sandwiched by the panel plate 1, particularly the plate. It is the main body 2. However, since the load applied to the floor panel is concentrated at the four corners of the plate body 2, that is, at the joints with the columns 6, the reinforcing material 23 made of synthetic resin or the like is embedded. By constructing the plate main body 2 using such a honeycomb structure 21, the load strength per thickness can be made sufficiently high. In addition, it can be made lightweight and rich in incombustibility and insulation, and its cost can be kept low.

Further, a packing material 24 having an L-shaped cross section and having a hollow portion at its bent portion is attached to each end of the plate body 2. This packing material 24
Is for sealing the gaps between the panel plates 1 when the panel plates 1 of the floor panels are butted against each other to form a floor. This sealing action is exhibited by elastic deformation of the hollow portion of the packing material 24.

Incidentally, instead of the packing material 24 having such a structure, a packing material having a concave portion on one panel plate 1,
A packing material having a convex portion may be provided on the other panel plate 1 so that the sealing action can be exhibited by fitting the concave portion and the convex portion. Panel board 1
Of course, it is also possible to form such projections and depressions on the ends themselves.

With such a structure, when the floor is cleaned or water is accidentally spilled, water enters the space between the panel board 1 on which the signal cables 12 are laid and the floor surface 9. There is no fear, and it becomes possible to obtain an effective waterproof effect.

9A and 9B, a composite cement material 26 mixed with glass fibers is used, and a foam polystyrene 27 is embedded in the composite cement material 26 to form the panel board 1 (board body 2). It is composed. Such a composite cement material 26 is also excellent in load strength per thickness and has nonflammability and insulation. Moreover, since it is inexpensive and has no fear of causing pollution during manufacturing, it is very useful as a constituent material of the panel board 1.

Also, if the above-mentioned packing material 24 is provided for the panel plate 1 having such a structure, it is practically convenient not only for providing the waterproof function but also for preventing the chipping of the end portion. . Further, the expanded polystyrene material 27 is used to prevent so-called warpage of the composite cement material 26, but since it has a soundproof effect, it has a great practical advantage. Further, such a panel plate structure can be easily manufactured by molding and the ribs can be easily manufactured, so that the load strength can be easily and effectively increased by the ribs.

As described above, the panel plate 1 is relatively easily manufactured in consideration of various specifications required for the floor panel. By the way, the panel plate 1 and the support column 6 are coupled to each other as follows. FIG. 10 shows an example thereof, in which the lower surface plate 4 is attached to the lower surface flange 61 of the column 6,
The lower surface plate 4 is supported and fixed by fitting a stop ring 31. The support column 6 is provided with a screw hole 32 extending from the upper end portion forming the pedestal 7 to the lower end portion thereof.
The panel plate 1 is fixed by a screw 10 which is inserted through a through hole 33 provided at a corner of the panel and screwed into the screw hole 32.

The through hole 33 is always covered with the surface material 3 and is exposed by turning the surface material 3. In this state, the plate body 2 is fixed to the column 6 by the screw 10. The leg portion 8 is screwed into the screw hole 32 from below. The leg portion 8 is rotated by a hexagonal wrench 34 inserted through a through hole provided in the center of the screw 10, whereby the downward protrusion amount of the leg portion 8 is adjusted. The screw 10 does not necessarily have to have the above-described through hole. In this case, the height of the leg portion 8 may be adjusted by the hexagon wrench 34 with the screw 10 removed.

As shown in FIG. 11, a hole 35 having a predetermined depth is provided at the upper end of the column 6, and the projection 36 provided on the plate body 2 is fitted into the hole 35 to integrate them. Is also good. Even in this case, the protrusion 36 should be provided with a hole for communicating the plate body 2, and the hexagon wrench 34 should be inserted through this hole so that the height of the leg 8 can be adjusted. Is practically preferable. Further, it is preferable to provide a cushioning material such as rubber at the tip of the leg portion 8.

According to the mounting structure of the column 6 and the panel plate 1 as described above, the panel plate 1 can be removed very easily, and the work for attaching the signal cable or the like can be easily carried out. Further, if the hole through which the hexagon wrench 34 is inserted is set to be equal to or less than the thickness of the surface material 3, the surface material 3 is hardly depressed into the hole. Therefore, it does not spoil the aesthetics of the floor. Even if a soft vinyl tile that can be rolled up is used as the surface material 3, scratches, contours, etc. due to the holes cannot be recognized from the surface material 3, so that its appearance can be maintained.

When a hard surface material is used as the surface material 3, the surface material 3 may be removed to perform the height adjustment of the legs 8 and the mounting / removing work of the plate body 2. . Also, only the relevant portion of the surface material 3 has a so-called lid structure,
It is also possible to have a structure in which only that portion can be removed.

Of course, instead of the hexagon wrench 34, the height of the leg portion 8 may be adjusted by a normal driver. Further, in the case of the structure shown in FIG. 11, since the panel plate 1 and the support column 6 are coupled only by fitting the protrusions 36 and the holes 35 provided in the plate body 2, so-called rattling between them may occur. To be done. However, apart from the support by the columns 6, the panel plates 1 are mutually regulated in position with the adjacent panel plates 1 and with the wall surface of the office, so that the problem of rattling can be offset. That is, it is possible to prevent rattling of the panel plate 1 for the entire floor. Further, according to such a configuration, the pillar 6 of the panel board 1
The mounting on the structure is reduced by the amount of the fixing work by the screw 10 described above, which is advantageous in carrying out the construction.

Although the basic structure of the panel according to the present invention has been described above, the present panel can be modified and implemented as follows. That is, in the previous embodiment, the columns 6 are provided for each panel, but as shown in FIGS. 12 and 13, a plurality of floor panels arranged on the floor 9 are targeted, and, for example, four corners are mutually connected. The four panel plates 1 and the lower surface plate 4 which are provided in parallel with each other may be used as one unit, and the columns 6 may be provided to support them simultaneously. In this case, the column 6 is adjusted in height with respect to the floor surface 9 and fixed at a predetermined position, and the panel 6 and the bottom plate are locked by being engaged with a claw 37, a pin or the like provided on the flange end of the column 6. 4 may be arranged and constructed respectively.

When the floor has a soundproof structure or a heat insulating structure, a soundproof material or a heat insulating material may be appropriately inserted in the upper space or the lower space. Further, as shown in FIG. 14, a sheet-shaped soundproof material 38 or a heat insulating material may be sandwiched between the plate body 2 of the panel board 1 and the surface material 3 to form a so-called sandwich structure.

In addition, for example, in the wiring work after the floor panels of the present invention have been spread, the panel board 1 can be easily lifted by inserting a tool or a finger into the recess cut portion 41. The work of attaching the cable extraction jig 42 or the power outlet 43 can be easily done, and the operability of the floor panel is extremely good.

Further, when laying the floor panels of the present invention, if the fingers are put on the recessed notches 41 and the panels are handled, there is no accident of pinching the fingers between the panels and the safety is excellent.

The present invention is not limited to the above embodiment. For example, the height of the upper space described above can be made variable, that is, the support position of the lower plate 4 can be moved up and down, and relatively large electric components can be accommodated. It is also possible to remove this bottom plate and perform panel laying work. Further, the number of columns 6 used here, the size of the panel plate 1 and the like may be appropriately determined according to the specifications. Further, it is of course possible to integrally provide the column 6 on the panel plate. In short, the present invention can be variously modified and implemented without departing from the scope of the invention.

As described above, according to the present invention, a notch portion having a locking portion having a predetermined step is formed on at least one side of a panel plate, and a blind plate or an outlet for closing the notch portion. Form a floor surface by laying basic panel board units equipped with components (eg, outlets and cable extraction parts) along the base body, and pull out cables at any position on the floor surface thus formed. In this case, the blind plate can be removed from the cut portion of the basic panel board unit arranged at the pull-out position, and the cables can be directly pulled out from the cut portion. Also, the cables can be pulled out through outlets that can be easily attached and detached by the step. Furthermore, since the cutout portion of the basic panel board unit arranged at a position where it is not necessary to pull out the cables is closed by the blind board, safety is ensured. Furthermore, by covering the upper surface of the panel board with the surface material, not only the appearance is enhanced, but also the safety is secured so that the blind board does not come off from the step.

Further, the engaging portion of the notch formed on the side portion of the panel plate has a predetermined step so that the upper surface of the panel plate and the upper surface of the blind plate have substantially the same height in the state where the blind plate is attached. By forming the floor structure, it is possible to form a floor surface structure excellent in safety and appearance. Moreover, since the notch is closed by the blind plate, the opening area can be made sufficiently large. Therefore, outlets can be easily attached, and a large amount of cables used for the OA office can be pulled out from the cut portion. Further, in the work of laying the panel board or the work of changing the layout, the panel board is lifted and lowered by placing a hand on the side of the panel board from the notch position of the panel board or the position of the notch of the adjacent panel board. You can For this reason, safety is considered so that hands are not sandwiched between the panel plates, and the work of laying the panel plates and the work of changing the layout can be performed safely and efficiently.
