Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a highly practical panel that facilitates the arrangement of network cables and their electrical components, and that can sufficiently cope with changes in the layout. Regarding.

[Technical background of the invention and its problems]

In recent years, due to significant technological innovations in microelectronic technology, efforts have been focused on the development of local area networks that interconnect multiple office automation devices. This local area network performs data communication at a high speed of 1QMbps, for example, between multiple workstations, a file device, a printer device, etc. via a transmission cable made of coaxial cables, optical fibers, etc. .

By the way, this type of local area network is one in which trunk cables such as coaxial cables and optical fibers are laid out vertically and horizontally within an office, and data is transmitted via these trunk cables. Therefore, in order to prevent accidents such as cable breakage caused by sudden repositioning of office automation equipment, electrical components such as couplers, transceivers, modems, etc. are placed near the above-mentioned main cable, and electrical equipment such as couplers, transceivers, modems, etc. Deriving the cable [7 Office automation machine i! i is connected. This prevents system failures of the entire network due to cable cutting accidents, etc., and improves its reliability to W6.

In addition, to build a local area network, the installation of the above-mentioned signal cables and products as well as the increase in power capacity due to the introduction of office automation equipment,
The number of electrical outlets will need to be increased, and installation work will also be required. Therefore, there is a strong demand for the development of a laying method that can easily carry out each of the above-mentioned laying works and can also adequately deal with layout changes after laying.

In order to meet such demands, raised floors have conventionally been used in computer rooms and the like. This free access floor has a floor panel with a diameter of 30 to 45 degrees raised approximately 15 to 30 degrees above the floor surface (slab), and signal cables, electric cables, etc. are installed between the floor panel and the slab. It is something to do. However, if this is adopted in a local area network,
There is a problem in that there are major restrictions on where electrical components can be fixed, and it is not possible to arrange them separately from other cables.

For this reason, during cable installation work, there is a risk that excessive force will be applied to the electrical equipment, causing damage to the electrical equipment, or even causing accidents such as contact between the electrical equipment and the electrical cable. For this reason, strict legal restrictions such as electrical equipment regulations are imposed on the installation work.

j7 This type of local area network installation is carried out in accordance with the layout specifications of the office, but in reality there are many changes to the above-mentioned layout, and each time it is necessary to consult the general assembly. Moreover, this work 1
1 is accompanied by severe constraints on the law tJd specified by the electrical equipment technical standards mentioned above, and therefore the above-mentioned layout could not be easily changed.

[Purpose of the invention]

The present invention has been made in consideration of these circumstances, and its purpose is to provide telecommunication system cables and electrical components of a local area network that interconnects a plurality of office automation devices, and furthermore, To provide a highly practical free access panel that facilitates the installation of power system cables and can sufficiently cope with changes in the layout of an office.

[Summary of the invention]

The present invention provides a first panel plate facing the first panel plate with a predetermined gap between the first panel plate and the first panel plate to allow cables, electrical equipment, etc. to be disposed therebetween. A second panel board provided, and a support that supports the second panel board and the first panel board by positioning the second panel board on the panel mounting part side and supporting the panel mounting part. This provides a panel equipped with

By laying panels with the above structure on, for example, a slab surface, free access to, for example, a local area network can be easily achieved.

〔Effect of the invention〕

Thus, according to the present invention, power system cables can be laid out by utilizing the lower space between the floor and the second panel board of the floor, which is constituted by a plurality of panels installed on the flag, for example. Moreover, since the signal cable and its electrical components can be placed using the upper space between the first panel board and the second panel board, it is possible to separate the signal system and the power system from each other. becomes. As a result, it becomes possible to easily and easily change the network equipment accompanying the layout change while satisfying legal restrictions. Therefore, great practical effects can be achieved, such as sufficient reliability of the network, etc. [Embodiments of the Invention] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an exploded perspective view of a panel according to a first embodiment in which the present invention is applied to a floor panel, and FIG. 2 is a diagram showing its side structure. The upper surface plate 1 as a first panel plate consists of a plate main body 2 and a surface material applied to the surface thereof. This top plate l is, for example, 4500 mm in consideration of workability, transportability, etc.
→×450 (b), and the board body 2 is a calcium silicate board, which will be described in detail later.

It is constructed using various materials such as particle board, honeycomb structural board, composite cement material, etc. At this time, the load bearing capacity required for the top plate l.

Needless to say, the constituent materials are selected with consideration to weight, thickness, insulation, fire resistance, economic efficiency, etc. Further, as the surface material 3, so-called vinyl tiles, carpets, jutetan, etc. are used, and these may be selected depending on the use and purpose.

On the other hand, reference numeral 4 in the figure indicates a lower plate as a second panel plate that pairs with the upper plate 1, and is made of, for example, an insulating plate. This bottom plate 4 is provided with a plurality of holes 5 arranged in a matrix for fixing electrical components as necessary.

As will be described later, this bottom plate 4 separates a space in which signal cables and electrical components constituting the network are arranged from a space in which power system cables are arranged.

These upper surface plate 1 and lower surface plate 4 are supported in parallel by four pillars 6 (6a, 6b, 6c, 6d) with a predetermined gap in between. The pillars 6 are fixed to each of the four corners of the lower plate 4, and a pedestal 7 is provided on the upper end surface at a predetermined height. The four corners of the upper plate 1 are each fixed on the pedestal 7, and an upper space with a height of 35 (M), for example, is formed between the upper plate 1 and the lower plate 4 with a predetermined gap in which signal cables and electrical components can be placed. A place is formed. In addition, the pillar 6
A leg portion 8 consisting of a screw mechanism that can move forward and backward by rotation is provided on the lower side of the lower surface plate 4. The protrusion distance of the leg portion 8 is adjusted so that the leg portion 8 protrudes downward from the bottom plate 4 and comes into contact with the floor surface (slab) 9. In this way, each support column 6 is provided on the floor surface 9, supporting the upper surface plate 1 and the lower surface plate 4, respectively. At this time, as shown in FIG.
A lower cavity of (mu) is formed. Incidentally, the upper surface plate 1 and the support column 6 are joined and fixed by, for example, screws 10 or the like. A specific example of this structure will be explained later.

Further, the support column 6 that supports the top plate 1 and the bottom plate 4 in this manner is made of, for example, cast iron, aluminum, or the like, or ceramic, synthetic resin, or the like having excellent insulation and economical properties.

Thus, the floor panel constructed in this manner is constructed by, for example, as shown in FIG.
The sheets are laid out on the office floor 9 with their ends butted against each other. At this time, a cable extraction jig 11 is provided at the end abutment location of the upper surface plate 1, if necessary. The cable take-out jig 11 and the like are attached using four notches provided at the end of the top plate l, as will be described later. Therefore, in the upper space formed between the upper surface plate 1 and the lower surface plate 4, a network trunk cable 12 such as an optical fiber or the same 1st pull cable is laid, and if necessary, a coupler, Electrical components 13 such as transceivers and modems are attached using holes 5 provided in the bottom plate 4. Then, a lead-in cable 14 is taken out from the electrical component I3 through the jig 11 to the upper surface of the upper plate I, that is, to the floor surface, and is connected to a predetermined office automation device. Further, in a lower space formed between the lower surface plate 4 and the floor surface 9, the signal cable 12 and the like are separated and a power system cable Z5 is installed. A power outlet etc. drawn out from this power system cable 15 is provided on the lower surface plate 4 or on the upper surface plate l as appropriate.

Thus, according to the raised floor constructed by this panel, the No. 44 system and the power system are separated by the bottom plate 4. and the lower space will be installed independently. Furthermore, it is possible to configure a network that satisfies various legal restrictions.

Therefore, in general, when it comes to installation work for a signal system consisting of a weak cardiac current circuit, office workers can carry out the construction work by office workers without interfering with the specialized construction work stipulated by law.
This can be done easily depending on the ball. In addition, as mentioned above, the signal system and
11□: Power system in minutes! As a result, there are no legal restrictions such as having to adopt an I/- lead structure or grounding work for signal cables and products. Dog q (It is possible to reduce the cost by simplifying the process.Also,
Electrical components 13 etc. can be easily fixed on the bottom plate 4, so when changing the installation etc.
It is possible to effectively prevent excessive force from being applied to the network, and the reliability of the network can be sufficiently maintained. Furthermore, the work required to change the network layout can be easily carried out by simply removing the top plate I. Furthermore, since the cables can be taken out from any desired position on a floor panel basis, it is possible to fully cope with changes in the layout associated with the movement of office automation equipment.

Furthermore, secondarily, all the cables and molding equipment can be housed within the floor panel, which improves the appearance of the office and eliminates the risk of accidents such as tripping over cables.

As mentioned above, the installation work of signal system cables can be easily carried out, but according to the law, the installation work of power system cables still needs to be carried out by specialized construction workers, which may prevent the above-mentioned layout changes. It becomes a factor. Therefore, if power outlets are attached to the bottom plate 4 at important points in advance during the initial installation of the power system cables, there is no need to perform power system work when changing the network layout. Therefore, if this is done, there will be no obstacles to changing the network, and a great practical effect will be achieved.

In addition, the legs 8 provided on the pillars 6 of the floor panel are
This is to adjust the quotient of the two-sided plate I to the floor surface 9 to form a uniform floor surface, but if the power system construction in the office is sufficiently completed, each leg It goes without saying that it is possible to make the height of each of the floor parts 8 and 8 sufficiently low, thereby making the entire floor surface low. Although four columns 6 are provided for each floor panel here, the support structure may be strengthened by adding additional columns to the center of the panel.

By the way, it is desirable that the upper surface plate 11, lower surface plate 4, and support column 6, which constitute the floor panel of the above structure, are specifically configured as follows.

Figure 4 (a), (b) and Figure 5 (a), (
b) C shows an example of the structure of the top plate I, and (a
1 is a partially cutaway plan view, and (b) is a longitudinal sectional view thereof. Generally, the load strength of an office is 300 (Kp/yn”
) and 1000 (K
P/n? ) or higher strength is not required. On the other hand, there are strong requirements for the flooring material to be lightweight, fireproof, insulative, thin in order to keep the floor height low and secure a wide space above the floor, and to be economical. Therefore, it is necessary to fully consider these requirements when configuring the top plate 1.

4(a) and (bl), a honeycomb structure 21 made of asbestos, aluminum, etc. is sandwiched between synthetic resin plates such as Bakelite or aluminum plates 22, and the upper plate 11, especially this, is used as the plate body 2. However, since the load applied to the floor panel is concentrated at the four corners of the board main body 2, that is, at the joints with the pillars 6, reinforcing materials 23 made of synthetic resin or the like are embedded. By constructing the plate body 2 using such a honeycomb structure 21, the load strength per thickness can be made sufficiently high.Moreover, it is lightweight, has high non-combustibility and insulation properties. It is possible to reduce the cost.Furthermore, each edge of the plate main body 2 has an rLJ-shaped cross section, and a hollow portion is formed at the bent portion. A backing material 24 of the following is applied.

This backing material; It is designed to be presented in a realistic manner. In addition, the backing material 24 having such a structure
Instead, a backing material having four parts on one top plate 1 and a convex part on the other top plate 1 may be provided, and the sealing effect may be exerted by the combination of these parts. Further, it is also possible to form such a concave and convex portion on the end portion of the upper surface plate l. With this structure, the signal cable 1 can be used when cleaning the floor or accidentally spilling water.
There is no risk of water entering the upper space where the second grade is installed,
It becomes possible to obtain the effective waterproofing effect.

5(a) and 5(b) show an upper surface plate 1 (plate body 2) having a structure in which a composite cement material 26 mixed with glass fiber is used and a styrofoam body 27 is embedded inside. Composite cement 26 also has excellent load strength per thickness, is nonflammable, has insulation properties,
It is useful as a constituent material of the top plate 1 because there is no risk of breakage during manufacturing and it is inexpensive. Further, if the backing material 24 as described above is provided for the top plate 1 having such a structure, it is practically convenient not only to provide a waterproof effect but also to prevent chipping of the end portion. In addition, the Styrofoam tube 2 embedded in the composite cement material 26
Reference numeral 7 is intended to prevent so-called warping of the composite cement pipe 26, and it also provides a soundproofing effect, which is a great advantage. Further, this structure can be easily manufactured by molding, and the lip can be easily made, so that the load strength can be effectively increased by the lip.

In this way, the top plate 1 can be easily manufactured while satisfying the specifications required for the floor panel.

By the way, the connection between the upper surface plate 1 and the support column 6 is performed as follows. Figure 6 shows an example of this.
The lower plate 4 is brought into contact with the lower flange 6a, and the retaining ring 31 is hidden therein to fixedly support the lower plate 4. A screw hole 32 is provided from the upper end forming the pedestal 7 to the lower end of this support 6, and the upper surface plate l is inserted into the through hole 33 provided at the corner thereof, and the screw hole 32 is inserted into the upper surface plate l. It is fixed by a screw 10 that is screwed into the. The through hole 33 is normally covered by the surface material 3, and is exposed by turning over the surface material 3.

In this state, the plate main body 2 is fixed to the support column 6 using the screws 10. Further, the leg portion 8 is screwed into the screw hole 32 from below. This leg portion 8 is connected to the screw 10.
The leg part 8 is rotated by a hexagonal wrench 34 inserted through a through hole provided in the center of the leg part 8.
The amount of downward protrusion of is adjusted. In addition, for screw IO,
There is no particular need to provide the above-mentioned through holes. In this case,
With the screw 10 removed, the height of the lever 11 portion 8 is adjusted using the hexagonal wrench 34.

As shown in FIG. 7, 35 holes of a predetermined depth are provided at the upper end of the support column 6, and the protrusions 36 provided on the plate body 2 are inserted into the holes 35.
It is also possible to have a structure in which the two are integrated by being fitted into it. Even in this case, a hole is provided in the protrusion 36 that communicates with the front and back surfaces of the plate body 2, and the hex wrench 34 is inserted through this hole.
Practically speaking, it is preferable that the height of the leg section 8 be adjusted by inserting the leg section. Also, the part provided at the tip of the leg part 8 is a loosely woven material made of, for example, rubber.

According to the structure, the attachment of the top plate I to the support column 6 is as follows:
The upper 111j board 1 can be removed very easily, making it possible to easily lay signal cables and the like.

Furthermore, if the hole through which the hexagonal wrench 34 is inserted is made to be equal to or less than the thickness of the surface material 3, the surface material 3 will hardly sink into the hole. Therefore, the aesthetic appearance of the floor will not be spoiled. Furthermore, even if a flexible vinyl tile that can be turned over and removed is used as the surface material 3, the scratches and contours caused by the holes cannot be seen on the surface material 3, so that the aesthetic appearance can still be maintained. If a hard material is used as the surface material 3, the height of the legs 8 is adjusted and the plate body 2 is attached after the surface material 3 is removed.

What is necessary is to perform the removal work. In addition, only the corresponding part of the surface material 3 is made into a so-called lid structure, and only that part is removed.
A possible configuration is also possible.

It goes without saying that instead of using the hexagonal wrench 34, the height of the leg portion 8 may be adjusted using a regular screwdriver. Historically, in the case of the structure shown in FIG. The so-called rattling is being worked hard. However, the top plate I is
Since the positions of the adjacent top plates 1 and the walls of the office are regulated independently of each other, the problem of rattling is effectively offset.

In other words, the upper surface plate l is prevented from wobbling as a whole of the floor. In addition, with this structure, the installation of the top plate 1 to the support column 6 is lightened by the fact that there is no fixing work using screws 10, which is a great advantage in terms of construction.

Although the eight-piece structure of the panel according to the present invention has been described above, the present invention can be implemented as follows.

That is, in the previous embodiment, the support column 6 was provided independently for one panel, that is, the pair of upper surface plate l and lower surface plate 4, but as shown in FIGS. Targeting a plurality of floor panels to be installed, for example, four upper plates L and four lower plates 4, whose four corners are butted against each other, are treated as one unit, and supports 6 are provided to simultaneously support them. Good too. In this case, the height of the support column 6 is adjusted with respect to the floor surface 9 and fixed at a predetermined position, and each upper surface plate l and lower surface plate 4 should be installed and constructed.

Also, if the floor has a soundproof or heat insulating structure,
A soundproofing material or a heat insulating material may be appropriately inserted into the upper part and the lower part. Also, as shown in Figure 10, the top plate l
A sheet-like soundproofing material 38 is placed between the board body 2 and the surface material 3.
It is also possible to use a so-called sandwich structure by sandwiching heat insulating material.

In addition, the signal cable laid in the upper space formed between the upper surface plate 1 and the lower surface plate 4 of the above-mentioned panel and the signal wire extraction from the metal product, and the connection between the lower surface plate 4 and the floor surface 9 The power can be taken out from the power system cable laid in the lower space between the two as follows. That is, the top plate I
As shown in FIG. 11, a recessed notch 4I is provided at the end of the recess 4I, and a cable extraction jig 42 (Il) and a power outlet 43 as shown in FIGS. 12(a) and (b) are installed in this notch 41. All you have to do is fit it in. Moreover, if it is not necessary to take these out, a blind plate 44 as shown in FIG. 12(C) may be fitted into the cut portion 41. Here, the cable extraction jig 42 includes, for example, two members 42a and 42b that divide the cable insertion hole 45 into two.
These members 42B and 42b are twisted so that the signal cable 12 and the like can be inserted into the insertion hole 45. This jig 42 is designed to protrude from the upper surface of the top plate l by a predetermined height, thereby preventing water from entering through the insertion hole 45 during floor cleaning, etc. There is.

By employing such a configuration, it becomes possible to take out the signal cable and the power supply line from any position on the floor in the office using the floor panel as a unit.

In addition, the power supply to the electrical equipment 13 installed in the upper space is as follows.
For example, as shown in FIG.
14, and a power outlet 47 as shown in FIG. 14 is attached to the four parts 46. Thereby, the mounting position of the electrical component I3 can be relatively easily removed.

As described above, according to the present invention, when constructing a local area network, the signal system and power system can be separated and cables can be laid easily. Furthermore, the electrical components I3 of the signal system can be accommodated in the upper space between the upper plate 1 and the lower plate 4. Therefore, the network can be organized in an orderly manner, and the aesthetic appearance of the office can be improved. Moreover, not only is the construction easy, but it can also accommodate changes in layout. Furthermore, since the floor panel itself can be realized at low cost, its practical advantage is enormous.

Note that the present invention is not limited to the above-described embodiments. For example, the height of the upper cavity can be varied, that is, the lower plate 4
The supporting position may be movable up and down, so that relatively large electrical equipment can be accommodated. Further, as described above, it is also possible to embed soundproofing material or the like in the empty space as appropriate. Further, the number of supports supporting the upper surface plate 1 and the lower surface plate 4, the size of the upper surface plate 1, etc. may be determined according to specifications. Further, although the explanation has been given using a floor panel as an example, it is also possible to apply the present invention to a ceiling panel, a wall panel, and the like. In short, the present invention can be implemented with various modifications without departing from the gist thereof.
