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 changes in the layout.

[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 high speeds, such as 10 Mbps, between multiple workstations, large-capacity file devices, printer devices, etc. via transmission cables made of coaxial cables, optical fibers, etc. It is.

By the way, in this type of local area network, trunk cables such as coaxial cables and optical fibers are laid out in all directions within an office, and data is transmitted via these trunk cables. Conventionally, in order to prevent accidents such as cable breakage due to the movement of office automation equipment, electrical equipment such as couplers, transceivers, modems, etc. are placed near the main cable, and the lead-in cables are routed from these electrical equipment. and connect office automation equipment. This prevents system downtime of the entire network due to cable cut accidents and increases its reliability.

Furthermore, in order to construct a local area network, it is necessary to install the above-mentioned cables and electrical equipment, as well as increase the power capacity and the number of electrical outlets due to the introduction of various office automation devices, which also requires installation work. Therefore, there is a strong demand for the development of a laying method that can facilitate the laying work and can adequately cope with layout changes after laying.

In order to meet such demands, raised floors have conventionally been used in computer rooms and the like. This raised floor has a side of 30
~45cm floor panel 15~ from the floor surface (slab)
It is intended to be installed at a height of about 30 cm and to lay signal cables, power cables, etc. between the panel and the slab. However, when 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 was a risk that excessive force would be applied to the electrical equipment, causing damage to the electrical equipment, or even causing an accident in which the electrical equipment came into contact with the power cable or the like. Therefore, strict legal restrictions such as electrical equipment technical standards are imposed on the installation work.

However, although this type of local area network installation work is carried out in accordance with the office layout specifications, in reality, the layout is often changed after the above-mentioned work is completed, and each time a large-scale change work is required. Moreover, since this construction work is subject to strict legal constraints specified by the electrical equipment technical standards mentioned above, it was not possible to easily change the layout.

Therefore, the present inventors previously proposed a panel having the following structure in Japanese Patent Application No. 83619/1983 (see Japanese Patent Application Laid-open No. 208898/1983). Figures 1 to 3
The figures show an example of this; FIG. 1 is an exploded perspective view of the panel, and FIG. 2 is a side view of the structure. The top plate 1 as the first panel plate is the plate main body 2.
and a surface material 3 attached to its surface. This top board 1 is set to have a size of, for example, 45 cm on each side in consideration of workability, transportability, etc. The board body 2 is made of calcium silicate board, particle board, honeycomb structure board, composite cement material, etc. It is constructed using various materials as appropriate. At this time, top plate 1
Needless to say, the constituent materials are selected taking into consideration the load resistance, weight, thickness, insulation, fire resistance, economic efficiency, etc. required for the structure. Further, as the surface material 3, so-called vinyl tiles, carpets, carpets, etc. are used, and these are also selected depending on the use and purpose.

On the other hand, the lower plate 4, which serves as a second panel plate and pairs with the upper plate 1, is made of, for example, an insulating plate. This bottom plate 4 is provided with a plurality of holes 5 in a matrix for fixing electrical components as necessary. As will be described later, this bottom plate 4 is
A space for installing signal cables and electrical components that constitute a network, which is provided between the top plate 1 and the floor surface (slab) 9 that is the base, is separated from a space for installing power system cables. It is something that forms.

Therefore, these upper surface plate 1 and lower surface plate 4 are
It is supported horizontally on the floor surface 9 by four pillars 6 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 face at a predetermined height. The four corners of the upper plate 1 are each fixed on the pedestal 7, and a first space is formed between the upper plate 1 and the lower plate 4 as an upper space in which a signal cable and electrical components can be arranged. Further, on the lower side of the lower plate 4 of the support column 6,
Leg portion 8 consisting of a screw mechanism that can move forward and backward by rotation.
is provided. By adjusting the amount of protrusion of the leg portions 8, the upper plate 1 and the lower plate 4 are disposed, for example, horizontally and in parallel on the floor surface 9 as shown in FIG. A second space is formed between the lower surface plate 4 and the floor surface 9, which are provided by adjusting the height. The support column 6 is made of, for example, cast metal such as iron or aluminum, or ceramic, synthetic resin, etc., which have excellent insulation properties and economic efficiency. Further, reference numeral 10 in the figure is a screw for fixing the top plate 1 to the support column 6.

According to the panel constructed in this way, for example, as shown in FIG. A single floor is formed. At this time, if necessary,
Cable extraction jig 1 is installed at the end butt point.
1 is provided. This cable extraction jig 11
is attached using, for example, a cutout recess provided at the end of the top plate 1. In the first space formed between the top plate 1 and the bottom plate 4, a trunk cable 12 such as an optical fiber or a coaxial cable is laid, and if necessary, electrical equipment such as a coupler, transceiver, modem, etc. The item 13 is attached using the hole 5 provided in the bottom plate 4. A lead-in cable 14 from this electrical component 13 is taken out through the jig 11 to the upper surface of the top plate 1, that is, to the floor surface, and connected to a predetermined office automation device. Further, in the second space formed between the bottom plate 4 and the floor surface 9, a power system cable 1 is installed.
5 is laid, and this power system cable 15 is electrically insulated and separated from the signal cable 14 and the like by the bottom plate 4. A power outlet etc. drawn out from this power system cable 15 is provided on the lower surface plate 4 and the upper surface plate 1 as appropriate, and power is supplied to the electrical components 13 and office automation equipment via this power outlet.

According to the free access floor constructed of panels having such a structure, the signal system and the power system can be laid separately and independently in the first and second spaces separated by the bottom plate 4. Because you can
It is possible to easily configure a network while fully satisfying various legal restrictions. Moreover, since the signal system is generally composed of weak current circuits, the installation work can be simply done by office workers according to the layout specifications, without having to outsource it to a legally required professional construction worker. be able to. In addition, since the signal system and the power system are separated by the bottom plate 4, there are no restrictions such as having to use a shield structure or a grounding structure for signal cables and electrical components. Therefore, it is possible to significantly simplify the signal system and reduce its cost. Furthermore, the top plate 1
Work associated with changing the network layout can be carried out on a panel-by-panel basis and from any position simply by removing the panels, so that it is easy to change specifications such as the network layout.

By the way, in a panel having such characteristics, the first and second space portions occupy a large space. Therefore, as an improvement on this, the present inventors have developed the fourth
We proposed a panel as shown in the figure. This panel has a structure in which the bottom plate (second panel plate) 4 is formed by pressing a vinyl steel plate with surface insulation treatment and has a stepped portion, and the top plate 1 and the base 9 are connected using this stepped portion. The limited space between the panels is effectively divided to form a wide first space in the center of the panel.
A second space is separately formed around the periphery. By turning the lower plate 4 over as appropriate and attaching it to the support column 6, the second space for accommodating, for example, surplus power cables as a pool can be set to be appropriately wide. Further, here, the support 6 for supporting the stepped portion of the bottom plate 4 is provided in common across a plurality of panels that are provided butt against each other, and the support 6
is fixed in advance at a predetermined position on the base 9,
The aim is to increase the strength of the floor formed by the panels, and to simplify the structure.

However, in the case of such a panel structure, after the pillars 6 are fixed to the base 9 in advance, the lower plate 4 etc. are installed on these pillars 6, but at this time,
So-called assembly distortion is likely to occur due to manufacturing dimensional errors of the lower plate 4, fixing position errors of the support columns 6, etc.
Further, there were other problems such as the possibility of misalignment with respect to other members. In particular, when the lower plate 4 is molded with resin, the dimensional errors caused by thermal shrinkage are large, resulting in many of the above-mentioned problems.

[Purpose of the invention]

The present invention was made in consideration of these circumstances, and its purpose is to further improve the above-mentioned panel structure and to create a highly practical panel that can facilitate the installation work. It is about providing.

[Summary of the invention]

The present invention provides a first panel board that is supported on a base via a support to constitute a floor surface, a wall surface, or a ceiling surface, and a first panel board that is supported by the support and between the first panel board and the base. a first space portion is provided between the first panel plate and the base body to form a first space portion between the first panel plate and the first panel plate, in which electrical equipment and signal cables can be disposed between the first panel plate and the base body; and a second panel plate forming a second space between the base body and the base body in which power system cables can be installed, and a support portion attached to the support of the second panel plate; For example, a wavy damper part exhibiting a hinge action is formed between the main surface of the panel to absorb assembly dimensional errors, etc., and the structure is such that this damper part absorbs manufacturing dimensional errors, assembly dimensional errors, etc. It is.

〔Effect of the invention〕

Thus, according to the present invention, the damper portion is provided on the second panel plate that is supported by the pillar and is provided between the first panel plate and the base to separate the first and second space portions. Therefore, the so-called hinge effect of the damper part effectively absorbs dimensional errors during installation work such as manufacturing dimensional errors of the second panel board and positional deviations with respect to the pillars fixed to the base. Since the second panel board can be fixed to the pillar, the accuracy of the installation work can be sufficiently increased, and the installation work can be performed easily. Therefore, it not only has the advantages of the panel structure proposed earlier, but also allows easy installation work without causing distortion problems caused by dimensional errors in manufacturing the panel board or dimensional errors in attaching the support to the base. Great effects can be achieved, such as being able to do the following.

[Embodiments of the invention]

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

FIG. 5 shows the structure of the lower plate (second panel plate) 4 according to the embodiment of the present invention, in which a is a plan view, b is a cross-sectional view, and c is an enlarged sectional view of a main part.
The lower plate 4 according to this embodiment has a step part of a predetermined height formed on its peripheral edge, and holes 21 for connection with the pillar 6 are provided in its four corners to serve as a supporting and fixing part for the pillar 6. . Further, a notch portion 22 that can be cut out or bent is formed in the center of the panel side portion connecting the supporting and fixing portions of the lower surface plate 4. The notch portion 22 is cut or bent as appropriate to form a communication path between the first space and the second space that are formed separately from the bottom plate 4. Therefore, as shown in FIG. Damper portions 4a each having a wave shape or the like are provided. This damper portion 4a exhibits a so-called hinge action by bending the wavy portion.
Here, each damper part 4a is formed as a single wave-like continuous body, but a notch is provided in the center of the damper part 4a to divide it into two parts having different bending directions.
The direction in which the hinge effect is exerted may be made independent.

FIG. 6 shows a cross section of a main part of a panel structure constructed using the second panel plate 4 provided with such a damper portion 4a.

That is, the second panel plate (lower plate) 4 is mounted by placing the edge portion forming the stepped portion on the upper plate 6b of the support column 6. Then, the second
panel board 4 and a pedestal 6c made of hard rubber material.
A first panel plate (top plate) 1 is placed and fixed via the. This first panel board 1 has four corner pillar fixing parts as thick parts with stepped parts of a predetermined height, and the height of the thick parts with respect to the first panel main surface is as described above. The height is set slightly higher than the height of the step formed at the edge of the second panel board 4. That is, the first panel board 1 has legs of a predetermined height formed at its four corners to be supported by the pillars 6. This leg allows the first
A space is formed between the main surface of the panel board 1 and the base body 9, in which the second panel board 4 can be stored by turning it upside down. Incidentally, positioning holes are provided at each of the four corners of the leg portion and the second panel plate 4, and the protrusions provided on the pedestal 6c fit into these holes to allow the first and second panel plates 4 to have positioning holes. The positioning between the second panel plates 1 and 4 is made. Further, the upper plate 6b of the support 6 on which such a pedestal 6c is placed is adjusted in height by screwing into a bolt body protruding from the lower plate 6a, and is positioned by a lock nut. be.

The damper portion 4a, which is a wavy portion having a predetermined height and is provided on the second panel plate 4, is provided so as to surround the leg portion of the first panel plate 1. When attaching the second panel 4 to the support 6 fixedly installed on the base 9, the hinge action of the damper portion 4a causes dimensional errors in the production of the second panel 4, and Errors in fixed installation positions can be absorbed. Further, as shown in FIG. 6, the damper section 4a is arranged such that the signal cable 12 laid on the stepped portion of the second panel board 4 is connected to the leg section of the first panel board 1 supported by the support column 6. It also functions as a protective wall for the cables, preventing them from being crushed by the cables.

However, if the second panel plate 4 is attached to the support column 6 in the normal state so that its main surface is close to the base 9 as shown by the solid line in FIG. Similarly, a sufficiently large first space can be formed between the first panel board 1 and the second panel board 4 in which electrical components can be stored. Then, a second space can be formed between the edge portion of the second panel board 4 where the stepped portion is formed and the base body 9, which serves as a space for installing the power system cable.

In addition, basically, in a panel that is installed and assembled as described above, when storing surplus power cables in the second space, the second panel board 4 in that area is connected to the dotted line in Fig. 5. As shown, the front and back sides are reversed, that is, the main surface is the first
It is attached to the support column 6 so as to be close to the panel board 1 of. In this case, this makes the first space very narrow, making it impossible to store electrical components there; however, on the contrary, a second space is created between the second panel board 4 and the base 9. It will be formed sufficiently wide. Therefore, it becomes possible to store the surplus power system cable in this wide second space in a so-called unrolled manner. On a raised floor constructed with this type of panel, electrical items can only be stored in specific panel positions according to the system specifications, and these panel positions should be avoided and By reversing the front and back sides of the second panel board 4 and assembling the panel, it is easy to secure a storage area for the power system cable.

As described above, in the panel of this structure, the first panel plate 1 and the base 9 form a space in which the second panel plate 4 can be stored by turning it upside down, and is supported by the pillar 6. The second panel board 4 supports the step-formed edge on the support 6, and the first panel board 1
and the base 9, so electrical components can be stored in the first space separated by the second panel board 4, or surplus power cables can be stored in the second space. The necessary space can be easily and sufficiently created by simply turning the second panel board 4 upside down and attaching it to the support column 6 depending on whether it is to be stored. Moreover, it still has the advantages of the panel structure proposed earlier. Furthermore, as described above, since the damper portions 4a are provided at the corners of the second panel board 4, the second panel board 4 can be manufactured by vacuum forming or injection molding, for example, polypropylene, vinyl chloride resin, etc. , even if the manufacturing dimensional error is large, the support 6
Even if the fixed installation position accuracy is poor, these dimensional errors can be effectively absorbed by the hinge action of the damper portion 4a. Therefore, the installation work can be easily carried out, and great effects such as being able to effectively insulate and separate the power system cable, signal cable, and electrical equipment can be achieved.

The second panel plate 4 is formed by press-forming a vinyl steel plate, for example, but is made of ABS.
It may also be molded by hot pressing a resin, polyethylene, polypropylene, polystyrene, or the like. Alternatively, it may be formed by injection molding of polyethylene or polypropylene, or further by injection molding of polyester, urethane, or the like. At this time, it is also useful to mix additives into the forming material of the second panel board 4 as required, thereby imparting flame retardancy to the second panel board 4. In this case, it is preferable to simultaneously form the aforementioned notch portions, for example, as notches or perforations in the panel board.

By the way, as shown in FIG.
They may also be connected by fasteners 23. This nylon fastener 23 consists of a plunger 23a and a gromnet 23b, and when the plunger 23a is pushed in, the tip of the gromnet 23b opens to fix the member sandwiched between them. It is something to do. By using such nylon fasteners 23, it is possible to securely and firmly fix and support the second panel plate 4 to the support column 6, and it is also possible to easily attach and detach the second panel plate 4. That is, the panel construction work involves attaching the second panel plate 4 to the support column 6,
This is done by, for example, attaching the first panel plate 1 to the support column 6 while riding on the second panel plate 4. At this time, if the second panel board 4 is only mounted by placing it on the pedestal part of the support column 6, when the worker stands on the second panel board 4, the second panel board will be damaged due to the weight of the worker. The second panel board 4 may come off the support column 6 due to the so-called warpage of the second panel board 4. In this regard, if the second panel board 4 is securely fixed to the support column 6 using the nylon fasteners 23 as described above, the above-mentioned problem will not occur, and the fixation will be done using the nylon fasteners 23. - Since this is done using the fasteners 23, the second panel plate 4 can be easily removed if necessary. Therefore, it has a great practical effect, such as making it possible to further improve the ease of installation work.

In this case, the grommet 23b may be formed integrally with the second panel plate 4 as shown in FIG. In this way, it is possible to reduce the manufacturing cost.

On the other hand, as shown in FIG. 9, there is a "V"-shaped groove 25 in the step part of the second panel board 4, which can be separated as needed.
It is also possible to provide a structure in which the groove 25 is cut with a cutter or the like to separate the central part of the panel from its peripheral part. By configuring the second panel board 4 in this way, for example, as shown in FIG. 9b, by cutting off the center part of the panel and dropping the center part of the panel into the peripheral part of the panel, It becomes possible to flatten the panel surface as shown in FIG. Particularly at this time, by leaving the four corners of the stepped portion on the main surface side of the panel and allowing it to fall in as it is, it is possible to position the central part of the panel with respect to the panel periphery, and at the same time, it is possible to position the center part of the panel with respect to the panel peripheral edge. The four corner portions can be used as partition walls for cables installed in the second space.

By configuring the second panel board 4 so that it can be flattened as appropriate, the second space can be set appropriately wide, and the degree of freedom in laying power cables can be increased. becomes. That is,
According to the second panel board 4 having the above-described configuration, the second space portion in which the power cables are arranged is formed in a so-called square shape at the peripheral edge of each panel, and
By turning the panel board 4 over, a second space is formed at that location. However, when a large number of power cables are installed together in the trunk direction, each second
It is sufficient if the panel plates 4 are respectively provided upside down, but the first space becomes extremely narrow at these panel positions. As a result, it becomes extremely difficult to route signal cables across these panel locations into the first space.

In this regard, if the second panel board 4 is configured to be flattenable as described above, for example, the first
As shown in Figure 0, the panel at a predetermined position of a plurality of panels constituting one floor is turned over with the second panel board 4 (X in the figure), and the second panel at a predetermined position on that line is By flattening the panel board 4 (Y in the figure), it becomes possible to easily form a first space in which a signal cable that crosses the main line can be placed. Therefore, the degree of freedom in laying the signal cable is not hindered, and effects such as simplification of the installation work and management thereof are achieved, and the practical advantages are enormous.

Note that the groove 25 that allows the second panel board 4 to be flattened may be formed integrally when the second panel board 4 is formed. In addition, the groove 25
Instead, so-called perforations may be formed.In short, it is desirable that the second panel plate 4 has a structure that can be flattened as appropriate.

Note that the present invention is not limited to the above embodiments. For example, although a panel having a structure in which the first and second panel plates 1 and 4 are simultaneously supported by the upper plate 6b has been described here, the first
The panel structure may be such that the panel board 1 and the second panel board 4 are independently supported by the support columns 6. In other words, the support position of the second panel board 4 may be fixedly determined, and the support position of the first panel board 1 may be variable using the support column 6, or the support position of the first panel board 1 may be fixedly determined and supported. It is also possible to use a support 6 that can freely change the supporting position of the second panel board 4 with respect to the first panel board 1. Furthermore, the structure and shape of the damper section can be modified in various ways. Furthermore, the supports 6 of the second panel board 4
The mounting structure and other configurations may be determined according to the specifications required for the panel. In short, the present invention can be implemented with various modifications without departing from the gist thereof.
