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, due to 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, 10Mb/s, between multiple workstations, large-capacity file devices, printer devices, etc. via transmission cables made of coaxial cables, optical fibers, etc. be.

By the way, this type of local area network is one in which trunk cables such as coaxial cables and optical fibers are stretched across offices, and data is transmitted via these trunk cables. And conventionally, Office O1
In order to prevent accidents such as cable breakage due to the movement of the equipment location of hemation equipment, electrical components such as couplers, transceivers, modems, etc. are placed near the main cable, and the drop-in cables are led out from these electrical components. Connecting office automation equipment. This prevents system failures 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 equipment, 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 changes in the layout after installation.

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 side of 30 to 45 cm raised approximately 15 to 30 cm above the floor surface (slab), and signal cables, electric cables, etc. are installed between the panel and the slab. It's something you can do. 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, 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 an accident in which the electrical equipment and the power cable come into contact with each other. For this reason, strict legal restrictions such as electrical equipment technical standards are imposed on the installation work.

However, this type of local area network installation work is carried out according to the specifications of the office, but in reality there are many changes made after the above construction.
In each case, personal changes were required. Moreover, since this construction work is accompanied by strict legal constraints specified by the electrical equipment technical standards mentioned above, it has not been possible to easily change the layer 1.

Therefore, the present inventors previously proposed a panel having the following structure in Japanese Patent Application No. 83619/1983. FIGS. 1 to 3 show an example thereof, with FIG. 1 being an exploded perspective view of the panel, and FIG. 2 being a side view of the structure. A top plate 1 as a first panel plate is composed of a plate main body 2 and a surface material 3 attached to the surface thereof. This top plate 1 has workability,
The board body 2 is set to a size of, for example, -45cIR in consideration of transportability, etc., and the board body 2 is constructed using various materials such as a calcium silicate board, a particle board, a honeycomb structure board, a composite cement material, etc. be done.

At this time, the weight resistance, weight, thickness, and
After considering insulation, fire resistance, economic efficiency, etc.,
It goes without saying that 4 II is selected.

Also, as the surface material 3, so-called vinyl tiles, carpella, jutan, 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 lower plate 1, is made of, for example, an insulating plate. This bottom plate 4 has holes 5 for fixing electrical components as necessary.
are provided in a matrix. As will be described later, this lower plate 4 is connected to the upper plate 1 and the floor (which is the base).
The installation space for the signal cables and electrical components that make up the C network is separated from the installation space for power system cables.

These upper plate 1 and lower plate 4 are supported in parallel on the floor surface 9 with a predetermined gap between them by four pillars 6 (6a, 6b, 6c, 6d).

The pillars 6 are fixed to each of the four corners of the bottom plate 4,
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, 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 portions 8 is adjusted so that the upper surface plate 1 and the lower surface plate 4
are arranged, 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 iron, aluminum, or the like, or ceramic, synthetic resin, etc., which have excellent insulation 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. 3, each end of each top plate 1 of a plurality of panels can be butted against each other and laid on the floor 9 of an office. Two floors are formed. At this time, if necessary, the ends of the top plate 1 butt 1! A cable extraction jig 11 is provided at the location. This cable extraction jig 11 is attached using, for example, a notch recess provided at the end of the top plate 1. Then, the top plate 1 and the bottom plate 4
A trunk cable 12 such as an optical fiber or a coaxial cable is laid in the first space formed between the

It will be done. Then, from this electrical component 13, the lead-in cable 1
4 is taken out through the jig 11 to the upper surface of the upper surface plate 1, that is, to the floor surface, and connected to a predetermined office automation equipment. Further, a power system cable 15 is laid in a second space formed between the bottom plate 4 and the floor surface 9, and this power system cable 15 is electrically separated from the signal cable 14 etc. by the bottom plate 4. Insulated. A power outlet etc. drawn out from this power system cable 15 is provided on the bottom plate 4 or the top plate 1 as appropriate, and power is supplied to the electrical components 13 and office automation equipment through this power outlet. It will be done.

Thus, according to the raised floor constructed of panels having such a structure, the signal system and the power system can be installed separately in the first and second spaces separated by the bottom plate 4. , 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 done simply by office workers, without having to entrust it to a legally-required specialist.
This can be easily done according to the layout specifications. 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. It becomes possible to significantly simplify the signal system and reduce its cost. Furthermore, just by removing the top plate 1, the network layerer 1 can be installed.
- Work related to changes can be done on a panel-by-panel basis and from any position, so the network layout] -
Effects such as easy specification changes can be achieved.

However, the panel having the above structure has a problem in that the first and second spaces occupy a large space. In other words, since the upper plate 1 and the base 9 are separated by the lower plate 4 to form the first and second spaces, it is possible to form a wide first space in which electrical components can be placed. In this case, it was necessary to provide the top plate 1 at a sufficiently high height relative to the base body 9.

Therefore, a large space was required for the equipment.

[Purpose of the invention]

The present invention has been made in consideration of these circumstances, and its purpose is to further improve the above-mentioned panel structure and to effectively utilize the limited space for laying electric horn cables. The object of the present invention is to provide a highly practical panel that can easily form a second space.

[Essentials of invention]

Alternatively, a panel board that constitutes the ceiling surface and forms a first space between the base body and which enables installation of electrical equipment and signal cables, and a plurality of the above-mentioned supports that support this panel board. A panel consisting of a cable cover member that is provided in between and forms a second space separated from the first space to allow installation of power system cables between the base and the base. A step portion formed at the edge of the support column by pressing a steel plate, for example, is used as a fixing portion to the base body, and a space portion communicating with a second space portion formed by the cable cover member. and an upper plate that is provided in a height-adjustable manner on the lower plate and supports the panel plate. be.

〔Effect of the invention〕

Thus, according to the present invention, the first and second spaces are formed by the lower plate of the strut and the cable cover member, and in particular, the second space is formed by the cable cover member and the lower plate of the strut. Since it is formed around the first space, no wasted space is created between the panel board and the base.Moreover, the inside of the lower plate of the support column forms the second space as it is. Therefore, it is easy to install power system cables there.Therefore, it not only has the advantages of the panel structure proposed earlier, but also has the second feature that makes it easy to install power system cables.
It is possible to effectively form a space, and furthermore, it is possible to achieve a compact panel structure that occupies less space, which is a great effect.

[Embodiments of the invention]

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

FIG. 4 shows an exploded view of a panel according to an embodiment of the present invention, and the same parts as those in the structure described above are given the same reference numerals and will be explained. The feature here is that instead of the second panel 4, a base (
A cable duct member 17 is provided by forming a second space between the cable duct member 17 and the lower plate 6X to form a second space between the upper plate (slab) 9 and the upper plate ( A second space is formed around the first space formed between the panel plate (panel board) and the base 9. That is, the lower plate 6x of the support column 6 is formed by pressing a vinyl steel plate, for example, to form stepped portions at its four corners, and uses the stepped portions as fixing portions to the base 9, and also has a central portion that is connected to the base 9. A space is formed between them. In this space, cable insertion holes are formed between the stepped portions formed at the four corners, that is, grooves formed on each of the four sides of the steel plate.

The end portion of the cable cover member 17 is connected to the cable insertion opening to form a second space between the cable cover member 17 and the base body 9 integrally. The cable cover member 11 has a duct shape with a cross section l'-1j, and is attached with its opening facing the base 9 and its end connected to the cable insertion opening of the lower plate 6x.

As a result, a second space is formed around the first space, separated from the first space.

Further, the lower plate 6x, which forms the second space in this way, is provided with an upper plate 6b whose height can be freely adjusted via a screw mechanism, etc., and the upper plate 6b is provided with an appropriate sliding friction on the upper plate 6b. The upper surface plate (panel plate) 1 is fixedly supported on the pedestal 6G. Electrical components 13 are disposed in the first space formed between the top plate 1 and the base 9. The electrical components 13 and the like are connected to a power system cable 15 installed in the second space.
Power is supplied as appropriate from the source.

As described above, according to the panel of this structure, since the second space can be effectively formed around the first space by the cable cover part (417), the upper surface plate 1 facing the base 9 can be effectively formed. Even if the height is reduced, it is possible to form a sufficiently wide first space in which electrical components 13 can be placed.

Furthermore, it is possible to easily lay power system cables in the second space. Since the support pillars 6 are connected by the cable cover member 11, the mechanical strength such as tensile strength can be made sufficiently high. Therefore, effects such as being able to improve earthquake resistance, stability, etc. can be achieved. Furthermore, this structure is simpler than the previously proposed structure, and its manufacturing cost is low. Moreover, since the floor surface 9 is exposed simply by removing the top plate 1, it is possible to carry out construction work by inserting foil there, and the workability is good. Therefore, the installation cost can be reduced, and there are many practical advantages such as excellent workability.

Note that the present invention is not limited to the embodiments described above. For example, as shown in FIG. 5, the cable cover member 17 may be composed of an upper cover member 17a and a lower cover member 17b. In this way, the second space can be surrounded by the cover members 17a and 17b, as shown in the cross-sectional configuration in FIG. 15 can be effectively shielded. Then, the electrical equipment 13 arranged in the first space part
This makes it possible to suppress adverse effects on the signal cable 12 and the like. Therefore, effects greater than those of the previous embodiments can be achieved.

Also, here we have explained the case where a raised floor is formed using panels, but the same applies to walls and ceilings.
Of course, it is also possible to configure a surface.

In addition, the present invention can be implemented with various modifications without departing from the gist thereof.
