Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a highly practical panel that allows network cables and their electrical components to be easily arranged, and that can sufficiently cope with layout changes.

[Technical background of the invention and its problems]

In recent years, with significant 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 high speeds of, for example, 10 Mbpg, between multiple workstations, large-capacity file devices, printer devices, etc. via transmission cables made of coaxial cables, optical fibers, etc. .

By the way, this glazed local area network is one in which trunk cables such as coaxial cables and optical fibers are strung 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 equipment such as Kagura, transceivers, modems, etc. are placed near the main cable, and cables are connected from these electrical equipment. Cables are routed to connect office automation equipment. This prevents system failures of the entire network due to cable cut accidents and increases its reliability.

In addition, in order to construct a local area network, it is necessary to install the signal cables and electrical equipment mentioned above, as well as increase the power capacity and number of outlets due to the introduction of various office automation equipment, and the installation work is also 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 that can 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 is 30~45c! A floor panel of IL0 is provided floating about 15 to 30 cIIL above the floor surface (slab), and signal cables, electric power cables, etc. are laid between the floor panel and the slab.

However, when this is adopted for 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, there was a risk that excessive force would be applied to the electrical equipment during the cable installation work, that this would cause damage to the electrical equipment, and that there would also be an accident in which the electrical equipment came into contact with the electrical equipment. For this reason, strict legal restrictions such as electrical equipment standards are imposed on the installation work.

However, when installing this type of local area network, new construction is carried out according to the layout specifications of the office, but in reality, the above-mentioned layout has to be changed frequently, and a large amount of installation work is required each time. Furthermore, this construction work was accompanied by strict legal constraints specified by the electrical equipment technical standards mentioned above, so it was not possible to easily change the layout.

Therefore, the present inventors previously proposed an -e channel having the following structure in Japanese Patent Application No. 58-83619.

FIGS. 1 to 5 show an example thereof, and FIG. 1 is an exploded perspective view of the No. J/Flannel, and FIG. 2 is a diagram showing its side structure. The top plate 1 as the first nozzle plate is the plate main body 2.
and a surface material 3 pasted on its surface. This top plate 1 has good workability.

For example, 450 (i+i) x 4 in consideration of transportability etc.
The size of the board 1 is set to 50 cm, and the board 1 body 2 is a calcium silicate board, particles #-)', no =
The cam structure structure is constructed using various materials such as plate laminated composite cement materials as appropriate. At this time, it goes without saying that the constituent material is selected after considering the load resistance, weight, thickness, insulation, fire resistance, economic efficiency, etc. required of the top plate 1.

Further, as the surface material 3, so-called vinyl tiles, carpets, jutetan, etc. are used, and these are also selected depending on the use and purpose.

On the other hand, reference numeral 4 in the figure designates a lower plate serving 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 lower plate 4 is provided between the upper plate 1 and the floor surface (slab) 9 that is the base body, and serves as a space for arranging signal cables and electrical components constituting a network, and for power system cables. This is to separate the space in which the

These top plate 1 and bottom plate 4 are supported parallel to each other on a floor surface (slab) 9 with a predetermined gap between them by four pillars 6 (6m, 6b, 6e, 6d). Ru. The pillars 6 are fixed, for example, to each of the four corners of the bottom plate 4, and have a pedestal 7 provided on the upper end surface at a predetermined height. The four corners of the top plate 1 are each fixed on the pedestal 7, and an upper space with a height of 35 (am), for example, is provided between the top plate 1 and the bottom plate 4 with a predetermined gap in which signal cables and electrical components can be placed. A place is formed. Further, on the lower side of the lower plate 4 of the support column 6, there is provided a leg portion 8 made of 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 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. 2, a lower space with an average height l 5 (mu), for example, is formed between the lower surface plate 4 and the floor surface 9, in which a power system cable can be placed. Incidentally, the upper surface plate 1 and the support column 6 are joined and fixed by, for example, screws 10 or the like. The pillars 6 that support the top plate 1 and the bottom plate 4 in this manner are made of, for example, cast iron, aluminum, or the like, or ceramic, synthetic resin, or the like with excellent insulation and economic efficiency.

The thus constructed floor panel is laid on the floor surface 9 of an office by, for example, as shown in FIG. 3, the ends of the top plates 1 of the plurality of floor panels are butted against each other. At this time, a cable take-out jig 11 is provided at the end abutment location of the top plate 1 as required. The cable extraction jig 11 and the like are attached by using, for example, a notch recess provided at the end of the top plate 1. In the upper space formed between the top plate 1 and the bottom plate 4, a network trunk cable 12 such as an optical fiber or coaxial cable is laid, and if necessary, a cable, transceiver, modem, etc. Electrical components 13 are attached using holes 5 provided in the bottom plate 4. Then, a lead-in cable 14 from this electrical component 13 is taken out through the jig 11 to the top surface of the top plate 1, the top surface of the top plate 1, and 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 15 is installed. And this power cable 1
A power outlet etc. drawn out from 5 are provided on the bottom plate 4 and the top plate 1 as appropriate.

Furthermore, in the structure shown in FIGS. 4 and 5, the upper plate 1 and lower plate 4 of the panel are individually supported by four supports 6, whereas the panel is supported on the floor surface 9. Four upper plates 1 and four lower plates 4, which are arranged with their four corners abutted against each other, form one unit, and are simultaneously supported by one support 6. The floor panel surface is constructed by bridging the upper surface plate 1 and the lower surface plate 4 between the pillars 6 provided at the butting points of the tabs, holes, and flannel.

Thus, according to the free access floor structured as described above, which is composed of multiple motherboards, the signal system and the power system are separated by the lower surface plate 4 in the upper space (first space) and the lower space. (the second space). Furthermore, it is possible to configure a network that satisfies various legal restrictions.゛Therefore, in general, when it comes to installation work for signal systems consisting of low current circuits, it is not necessary to outsource it to specialized construction workers as stipulated by law.
Office workers can easily do this according to their layout specifications. In addition, since the signal system and power system are separated by the bottom plate 4 as described above, there are legal regulations that require shielding structures and grounding work for signal cables and electrical components. Since there are no restrictions, it becomes possible to significantly simplify the signal thread and reduce its cost. In addition, since the electrical components 13 etc. can be easily fixed on the bottom plate 4, it is possible to effectively prevent excessive force from being applied to the electrical components 13 during installation change work, etc., thereby increasing the reliability of the network. can maintain a sufficiently high level of performance.

In addition, we will carry out construction work related to changing the network layout.
This can be easily carried out by simply removing the bottom plate 1.

Furthermore, since the cables can be taken out from any arbitrary position in units of four floor panels, it is possible to fully cope with changes in the layout accompanied by the movement of office automation equipment. Furthermore, secondarily, cables and
Since all the turtle devices can be stored within the floor panel, the office looks good and there is no risk of accidents such as tripping over cables.

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

Note that the legs 8 provided on the pillars 6 of the floor panel are as follows:
This is to adjust the height of the top plate 1 with respect to the floor surface 9 to create a uniform floor surface, but if sufficient power system construction has been carried out in the office, each leg 8
Needless to say, it is possible to lower the height of each of the floor surfaces sufficiently, thereby lowering the entire floor surface.

[Purpose of the invention]

The present invention further improves the previously proposed panel to provide an inexpensive and highly practical construction that increases the space efficiency of panel equipment and simplifies cable installation work. The purpose is to

[Summary of the invention]

The present invention provides a first panel board that is supported on a base via a support and constitutes a floor surface, a wall surface, or a ceiling surface, and a first panel board that is supported by the support and provided between the first panel board and the base. The second panel plate and the plate, especially the second panel plate, have a stepped portion of a predetermined height, and are divided into multiple parts by the stepped portion, and are separated from the first panel plate. The first space that is formed is used as a placement area for cables and electrical equipment, and the second space that is divided into multiple parts by the stepped part and formed between the base body and the base body is used as a placement area for cables and electrical equipment. It is characterized by having a structure in which the arrangement area is as follows.

〔Effect of the invention〕

Thus, according to the present invention, it not only has the advantages and effects of the previously proposed No4 panel, but also has a stepped portion between one side of the stepped portion and the first panel plate (top plate). A first space is formed in the other surface and the base (bottom surface).
The first and second panel plates are effectively separated from each other without increasing the space between the first panel plate and the base by the second panel plate forming a second space between the first panel plate and the base body. 2 spaces can be formed. In addition, the stepped portion of the second panel board makes it possible to reliably electrically insulate and separate the first and second spaces, making it possible to provide a robust partition wall between cables as specified by electrical equipment technical standards, etc. It becomes possible to easily and effectively satisfy specification conditions.

Furthermore, since the stepped portion forming the partition wall is integrated as the second panel board, there is no risk of hindering the installation work. Furthermore, the second panel board having the same structure is inexpensive because it can be easily manufactured by, for example, press processing, and the strength of the second panel board itself is increased by the stepped portion. , it is highly practical in terms of strength and structure.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 6 is an exploded perspective view showing the schematic structure of the panel according to the embodiment, and the same parts as those of the panel shown in FIGS. 1 to 5 proposed earlier are denoted by the same reference numerals. . , here, a top plate (first panel plate) 1 is shown in which jutan is pasted as a surface material 3 to a plate main body 2.

The lower surface plate (second panel plate) 4 according to this embodiment is formed by pressing a panel material made of, for example, a vinyl steel plate and subjected to surface insulation treatment, and has a stepped portion with respect to the Tsukuneru main surface 4a. A corner duct portion 4b and an edge duct portion 4C are formed respectively. The corner duct portions 4b are provided at the four corners of the panel by forming steps of height hl with respect to the main surface 4a, and the edge duct portions 4C are provided at the four sides of the /'e panel. They are provided by forming a step with a height hz (hz<hx) with respect to the surface 4a. In particular, the edge duct portion 4C is provided parallel to the side thereof, but the corner duct portion 4b is provided with a so-called chamfered stepped portion in multiple directions at an angle of 45° with respect to the corner. It is being A hole 21 for connection to the support column 6 is provided in this corner duct portion 4. Further, the corner duct portion 4b and the edge duct portion 4C are provided with a knock portion 22 that can be cut out as needed, and when the knock piece is removed, a hole portion or four portions 23 through which cables can be inserted are provided. is starting to form. and,
When the knock piece is decontaminated and the holes and recesses 23 are formed,
A rubber bush 24 is attached to the edge to prevent accidents such as peeling off of the cable coating due to the four-channel cutting edge for cables inserted there. Incidentally, instead of such a knock portion 22, a hole portion or a recess 23 may be formed in advance, and the portion may be closed with a blind plate when not in use.

On the other hand, the pillars 6 that support the first and second panel plates (top plate, bottom plate) 1.4, respectively, are attached to the lower plate 6m fixed to the base (floor varnish slab) 9, and to the lower plate 6a. It is constituted by an upper grate 6b1 which is attached with its height adjusted, and a pedestal 6C made of a hard rubber material, for example, which is fitted onto the upper plate 6b. That is, as shown in the cross-sectional structure of the main part of the support 6 in FIG. Adjust the screwing amount of the bolt part 26, and play depending on the screwing amount) 6a
, 6b can be adjusted. The locking annular body 27 embedded in the screw 25 is for locking the threaded state of the bolt part 26 and the screw 25 so that the threaded state thereof is not inadvertently displaced, and is made of resin such as Teflon. Made of wood.

The pedestal 6c is fitted onto the upper plate 6b whose height is adjusted by such a screw structure, and is provided so as to slide with appropriate friction between the pedestal 6c and the upper plate 6b. The lower plate 4 and the upper plate 1 are mounted and supported by engagement with locking pins 28 provided in four directions on the upper surface of the pedestal 6C, respectively. That is, the lower plate 4 is fixedly supported by the upper plate 6b of the support column 6 by inserting the locking pin 28 into the hole 2 provided in the corner duct portion 6b, and the upper plate 1 is inserted from above. The locking pin 28 is fitted into a hole provided at a corner of the plate main body 2, and the plate body 2 is fixedly supported by the upper grate 6b of the support column 6.

Incidentally, the support column 6 having such a structure may be constructed as shown in FIG. 8, for example. That is, the lower plate lower a may be constructed of a panel material formed into a so-called cap shape by press working, and a nut 29a may be welded to the head portion of the panel material, and a locking nut 29b may be further attached. As such a structure, the pillar 6 of the structure shown in FIG. 7 described above may be used.
It goes without saying that the same effects are exhibited.

Therefore, the height of the support column 6 that supports the top plate 1 and the bottom plate 4 in this manner, that is, the height of the top plate 6b relative to the bottom plate 6m, is adjusted as follows. A hexagonal hole 32 into which, for example, a hexagonal wrench 31 is fitted is provided in the center of the upper surface of the upper plate 6b, and the hexagonal wrench 31 is provided by cutting out part of the corner of the upper plate 1 and the lower plate 4. It is fitted into the hexagonal hole 32 through the hollow space. The main point is that the hexagonal wrench 31 is attached to a part of the corner of the upper surface plate 1 and the lower surface plate 4 which are disposed abutting each other.
It forms a hole through which the upper plate 1 can be inserted.
It is covered by the surface material 3. Then, if necessary, by flipping up a corner of the surface material 3, the hole is exposed, thereby making it possible to insert the hexagonal wrench 31. Therefore, the hexagonal wrench 31 fitted into the hexagonal hole 32 of the upper plate 6b allows the upper plate 6b to
When the upper plate 6b is rotated, the upper plate 6b slides between the base 6c and rotates, thereby moving up and down to change its height. The upper grate e whose height is adjusted in this way
b is then maintained in that state by the action of the locking hook 27 or the locking nut 29b.

Thus, according to the panel constituted by the upper plate 1 and the lower plate 4 supported by the pillars 6 having the above-described structure, since the lower plate 4 has the above-described step structure, the main panel of the lower plate 4 A wide first space is formed between the surface 4a and the top plate 1 in which cables and electrical equipment can be placed. At the same time, the corner duct portion 4b of the bottom plate 4
Although no space is formed between the edge duct portion 4c and the top plate 1, and only a small space is formed between the edge duct portion 4c and the top plate 1, the base (floor surface) of these duct portions 4b and 4c There is a second section between the
A space will be formed. The step part provided on the second panel plate (bottom plate) 4 allows the first
The limited space between the mother flannel plate (top plate) 1 and the base body (floor surface) 9 is effectively divided to form mutually isolated first and second space parts, respectively. Electrical components 13 are housed in the first space, as shown in FIG. 6, and a signal cable 12 is formed between the first space and the edge duct 4C and the top plate 1. It is arranged through a narrow space (forming a part of the first space). Further, the branch cable 14 from the electrical equipment 13 is
It is inserted into the jig I and pulled out to the top surface of the top plate 1 through a hole provided on the side thereof. On the other hand, electric cable 15
are arranged through a second space formed in a groove shape between the duct parts 4b, 4c and the base body 9.

At this time, since the height of the corner duct portion 4b relative to the base body 9 is set higher than the edge duct portion 4C, the plurality of power cables 15 are arranged to cross each other with sufficient margin at this portion. It is possible to do so. Further, as described above, since the corner duct portion 4b has a shape that is chamfered in the same direction, this corner duct portion 4b
It is possible to arrange the power cable 15 in a gently curved manner in the second space formed in the second space. Moreover, the second space portion in which the electric power cable 15 is disposed in this way is
Since the structure is completely isolated from the first space by the stepped part of the second flannel plate 4, installation of the electric cables 15 must be carried out after fully satisfying the electrical equipment standards. Make it possible. And these electric cables 15
is a hole 2 formed by the knock part 22 as necessary.
3 into the first space and supplied power to the electrical equipment 13 provided there, or taken out onto the nozzle via the jig 11. . Therefore, it is possible to spread the network extremely effectively within the panel, and it is also possible to sufficiently deal with changes in the layout.

Regarding the electrical equipment 13 to be housed in the first cabinet section mentioned above, a heat conduction plate 35 is provided as shown in FIG. 6, and this plate 35 is connected to the edge duct of the second panel board 4. What is necessary is just to fix it to part 4c. Further, at the same time, the second plates 4 disposed adjacent to each other may be interconnected by the heat conductive plate 35. In this way, it is possible to further increase the bonding strength between the second plates 4, and to effectively dissipate heat from the electrical components 13 through these second plates 4. is possible, and its practical advantages are great.

Although the embodiments of the four-channel system according to the present invention have been described above, the present invention can also be modified and implemented as follows. For example, here we have shown a structure in which each of the four corners of the panels that are placed abutting each other is supported by one support 6, but as shown in Figure 1, each panel is It is similarly applicable to a structure supported using four independent columns 6. It is also effective to provide a hole in the center of the panel main surface 4a of the M2 panel board 4, which is large enough to allow a foot to step through. In this way, it is possible to step into the floor surface 9 through the hole and perform cable installation work or cable installation work without having to provide the second panel board 4 with any additional strength. Become. Regarding the knock part 22 provided in the second flute plate 4, for example, as shown in FIG.
All you have to do is to form . That is, the knocking part 22 is normally provided with supporting parts 36 formed at various places on the side forming the hole 23, but with this structure, when the knock piece is removed, the cut part of the supporting part 36 is placed as a protrusion. . The formation of cracks has the potential to cause tears in the cable sheathing. In this regard, as described above, if a knock is formed in the shape of Ω from the side where the hole 23'f is formed, and the support part 36 is formed at the top of the knock, the support part 36 can be cut to form a protruding shape. Even if this happens, the protrusion remains within the recess, so there is no possibility that the protrusion remains on the side of the hole 23. Therefore, with such a structure, there is an advantage that there is no need to take measures such as securing the edge portion with the rubber bush 24 described above. In addition, in the above-described embodiment, the upper plate 6b is
It goes without saying that the height may be adjusted using a Phillips screwdriver, a flathead screwdriver, or a special jig. It is also useful to fit a blind plate into the hole in the top plate 1 through which the hexagonal wrench 31 or the like is inserted. Furthermore, a plurality of second panel plates (lower plate 4) are provided, and water pipes, gas pipes, air-conditioning ducts/pipes, etc. are separated from each other along with the cables in the spaces formed between these panels. It is also possible to arrange it as follows. In addition, the present invention can be applied to wall panels, ceiling panels, etc., and can be implemented with various modifications without departing from the gist thereof.

As described above, according to the present invention, the second panel plate is formed to have a stepped portion, and the stepped portion effectively isolates the space between the first panel plate and the base body. Since each space is formed separately, it is possible to lower the height of the panel surface compared to the previously proposed four-channel panel, and it is extremely effective, such as making effective use of the equipment space. This produces a certain effect. Moreover, it can be manufactured at low cost,
It has advantages such as low installation cost, but it is not practical.
