Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a highly practical panel that allows a network cable and its electrical components to be easily arranged, and can sufficiently cope with a layout change.

[Technical background of the invention and its problems]

Recently, efforts have been made to develop a local area network that connects a plurality of office automation devices to each other against the backdrop of remarkable innovation in microelectronics technology. This local area network performs data communication between a plurality of workstations and a large-capacity file device, a printer device, etc. at a high speed of, for example, 10 Mbps via a transmission cable such as a coaxial cable or an optical fiber.

By the way, in this type of local area network, a trunk cable such as a coaxial cable or an optical fiber is stretched vertically and horizontally in an office, and data is transmitted through the trunk cable. In the past, in order to prevent cable disconnection accidents caused by movement of the office automation equipment, etc., electrical components such as couplers, transceivers, and modems were placed near the main cable, and lead-in cables were derived from these electrical components. Then connect the office automation equipment. As a result, system down of the entire network due to a cable disconnection accident, etc. is prevented and its reliability is improved.

Further, in order to build a local area network, it is necessary to lay the above cables and electrical components, as well as to increase the power capacity and the number of outlets accompanying the introduction of various office automation equipment, and the laying work is also required. Therefore, it is strongly desired to develop a laying method that can facilitate the laying work and can sufficiently deal with the layout change after the laying.

In order to meet such a demand, a free access floor is conventionally used in a computer room or the like. In this free access floor, a floor panel having one side of 30 to 45 cm is floated about 15 to 30 cm above the floor surface (slab), and a signal cable, a power cable or the like is laid between the panel and the slab. Is. However,
If this is adopted in a local area network, there is a problem that the fixing location of electrical components is greatly restricted and it cannot be arranged separately from other cables. For this reason, there is a possibility that an unreasonable force may be applied to the electrical equipment during cable laying work, the electrical equipment may be damaged, or a contact accident between the electrical equipment and the power cable or the like may occur. For this reason, strict legal restrictions such as electrical equipment technical standards are imposed on the laying work.

However, the construction work of a local area network of this kind is performed according to the layout specifications of the office.
In reality, there were many layout changes after the above construction, and each time large-scale change work was required. Moreover, since this construction involves severe restrictions on the laws and regulations indicated by the above-mentioned electrical equipment technical standards, it was not possible to easily make this layout change.

Therefore, the present invention has previously proposed a panel having the following structure in Japanese Patent Application No. 58-83619 (Japanese Patent Application No. 59-208898). FIG. 1 to FIG. 3 show an example thereof, FIG. 1 is an exploded perspective view of a panel, and FIG. 2 is a view showing a side structure thereof. A top plate 1 as a first panel plate is composed of a plate body 2 and a surface material 3 attached to the surface thereof. The top plate 1 is set to have a size of, for example, 45 cm on one side in consideration of workability and transportability, and the plate body 2 is made of calcium silicate plate, particle board, honeycomb structure board, composite cement material, or the like. It is configured by appropriately using various materials. At this time, it goes without saying that the constituent material is selected in consideration of load resistance, weight, thickness, insulation, fire resistance, economy and the like required for the top plate 1. The surface material 3 is a so-called vinyl tile,
Carpet, jutan, etc. are used, and this is also selected according to the use and purpose.

On the other hand, the lower surface plate 4 as a second panel plate that makes a pair with the upper surface plate 1 is formed of, for example, an insulating plate. The lower surface plate 4 is provided with a plurality of holes 5 in a matrix shape for fixing electrical components if necessary. This bottom plate 4
As will be described later, is a space for arranging the signal cables and electric components that are provided between the upper plate 1 and the floor (slab) 9 that is the base body to form a network, and a space for arranging the power system cables. And are formed separately.

The upper plate 1 and the lower plate 4 are supported by the four columns 6 (6a, 6b, 6c, 6d) in parallel on the floor 9 with a predetermined gap. The columns 6 are fixed to the four corners of the lower plate 4, respectively, and a pedestal 7 is provided on the upper end face of a predetermined height. The four corners of the upper plate 1 are fixed on the pedestal 7, and a first space in which a signal cable and electrical components can be arranged is formed as an upper space between the upper plate 1 and the lower plate 4. On the lower side of the lower surface plate 4 of the pillar 6, a leg portion 8 formed of a screw mechanism that can freely move back and forth by rotation is provided. The amount of protrusion of the legs 8 is adjusted so that the upper plate 1 and the lower plate 4 are arranged on the floor 9 in a horizontal and parallel manner, for example, as shown in FIG. Then, the lower surface plate 4, the floor surface 9 and the second space provided by adjusting the height are formed. The pillar 6 is made of, for example, a cast product of iron, aluminum, or the like, or a ceramic, a synthetic resin, or the like having excellent insulating property and economical efficiency. Reference numeral 10 in the figure denotes a screw for fixing the top plate 1 to the column 6.

Thus, according to the panel configured as described above, for example, as shown in FIG. 3, one end of each top plate 1 of a plurality of panels is abutted against each other and laid on the floor 9 of the office. Two floors are formed. At this time, a cable take-out jig 11 is provided at the end butting portion of the top plate 1 if necessary. This cable extraction jig 11
Are attached using, for example, notched recesses provided at the end of the top plate 1. A main cable 12 such as an optical fiber or a coaxial cable is laid in the first space formed between the upper plate 1 and the lower plate 4, and if necessary, electrical equipment such as a coupler, a transceiver and a modem is installed. The item 13 is attached using the hole 5 provided in the lower plate 4. Then, the lead-in cable 14 is connected to the jig 11 from the electrical component 13.
Is taken out to the upper surface of the upper surface plate 1, that is, the floor surface, and connected to a predetermined office automation device. A power system cable 15 is laid in a second space formed between the lower surface plate 4 and the floor surface 9. The power system cable 15 is electrically connected to the signal cable 14 and the like by the lower surface plate 4. Isolated. A power outlet or the like pulled out from the power system cable 15 may be a bottom plate 4 or a top plate 1 as appropriate.
Is installed in the electrical component 13 through the power outlet.
And office automation equipment is powered.

Thus, according to the free access floor configured by the panel having such a structure, the signal system and the power system can be separately installed in the first and second spaces separated by the bottom plate 4. The network can be easily configured by sufficiently satisfying various legal restrictions. Moreover, since the signal system is generally composed of a weak current circuit, the laying work is simply done by an office worker according to its layout specifications without entrusting it to a specialist contractor stipulated by law. be able to. Further, since the signal system and the power system are separated by the lower surface plate 4, there are no restrictions such as the need to adopt a shield structure or a ground structure for the signal system cables and electrical components. It is possible to greatly simplify the signal system and reduce the cost. Furthermore, by simply removing the top plate 1, the work involved in changing the layout of the network can be performed on a panel-by-panel basis and from any position, which makes it easy to change the specifications such as the layout of the network. .

By the way, although the panel having the above-mentioned structure has many advantages, the upper surface plate (panel plate) is made of an inexpensive material such as a composite cement material such as GRC (glass fiber reinforced cement) or asbestos. Then, if the required strength is secured, it becomes thick and heavy. Therefore, it cannot be denied that considerable labor is required for the panel laying work. Therefore, the panel plate is configured in consideration of the workability of such a panel, but there are many problems in terms of soaring material costs, transportation cost for panel work, workability, etc. there were. Furthermore, the first
Further, in order to form the second space portion sufficiently wide, the upper surface plate (panel plate) needs to be provided at a high position with respect to the floor surface, and a large occupied space is required.

[Object of the Invention]

The present invention has been made in consideration of such circumstances, and an object of the present invention is to improve the workability and transportability by making the panel plate have necessary strength and reducing its weight and thickness. The purpose is to provide an inexpensive panel.

[Outline of Invention]

The present invention supports a floor surface, a wall surface,
Alternatively, in a panel provided with a panel plate constituting a ceiling surface, the panel plate is formed by press molding, and an inorganic or organic molded body that is filled and molded into the steel plate using this steel plate as a mold. It is a feature.
The stepped portion is utilized to effectively form the installation space for electrical components and the like without occupying a large space.

〔The invention's effect〕

Thus, according to the present invention, since the panel plate is formed by press-molding a steel plate, and the inorganic or organic-based molded body that is formed by filling the steel plate with the steel plate as a mold,
It is possible to reduce the plate thickness and to reduce the weight while sufficiently ensuring the mechanical strength. Therefore, it is possible to significantly improve the transportability and the workability in the panel laying work. Further, since the panel plate is composed of the press-molded steel plate and the molded body made of an inorganic or organic material filled in the steel plate, the material cost and the manufacturing cost thereof can be sufficiently reduced. Furthermore, since it is possible to form the first and second spaces which are insulated and separated from each other without causing unnecessary occupation space by the stepped portion provided on the panel plate, its practical advantage is great.

Example of Invention

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 4 is an exploded view of the panel according to the embodiment, and FIGS. 5 and 6 are configuration diagrams of main parts thereof. Incidentally, the same parts as those shown in FIG. The top plate (panel plate) 1 is press-molded and has stepped portions at its four corners.
21 is formed, and a steel plate 23 having a rib 22 in the shape of a cross in the central portion, and a molded body made of an inorganic or organic system filled in the steel plate 23 as a mold, for example, a GRC 24, A surface material 3 such as jutan is provided on the surface of the GRC 24. The steel plate 23 has, for example, a step portion 21 having a height of 30 mm and a rib 22 having a height of about 5 to 10 mm and a side 45.
It has a size of about cm, and its edges are bent to form one mold. The mold is filled with GRC24.

On the other hand, the lower surface plate 4, which is the second panel plate, is made of press-molded vinyl steel plate, and has corner step portions 25 with a height of about 40 mm at its four corners and heights at the edges connecting these corner step portions 25. A duct step 26 of about 20 mm is formed. The corner step portion 25 is so-called chamfered at an angle of 45 ° with respect to the corner. Further, the duct step portion 26 is provided with a knock portion 29 that can be cut off as needed, and when the knock piece of the knock portion 29 is removed,
Holes, recesses, and the like are formed therein so that cables can be inserted therein. When a recess or the like is formed excluding the knock piece, a rubber bush or the like is attached to the edge of the recess to prevent accidents such as peeling of the coating of cables inserted through the recess. .
Instead of such a knock portion, a hole or a recess may be formed in advance in the step 26, and when not used, the part may be closed by a so-called blind plate.

Then, the upper plate 1 and the lower plate 4 are attached to the columns 6 by fitting the positioning holes respectively provided at the stepped portions at the four corners of the upper plate 27 of the columns 6. Stanchion 6
Is composed of a lower plate 28 fixed to the base body (slab) 9 and the upper plate 27 connected to the lower plate 28 through a screw mechanism. The upper plate 27 of the upper plate 27 with respect to the floor surface is fixed by the screw mechanism. The height is adjusted. FIG. 6 shows a sectional structure of the panel assembled in this manner. As shown in this figure, the panel is a bottom plate on the upper plate 27 of each strut 6 over the strut 6 fixed on the base body 9 at a predetermined interval.
It is constructed by attaching the top plate 1 via 4. A space for accommodating electrical components is formed between the upper surface plate 1 and the lower surface plate 4 by abutting the step portions. Further, between the lower surface plate 4 and the base body 9, the lower surface plate 4
The stepped portions 25 and 26 form a space in which the power system cables can be arranged. Then, the lead-out cable from the electrical component 13 and the lead-out line from the power system cable laid in the upper space are provided on the edge of the top plate 1.
It is pulled out to the upper surface of the panel through 11.

Therefore, even a panel having such a structure can achieve the same effect as that of the structure shown in FIG. 1 previously proposed.
In addition to this, as described above, since the upper surface plate (panel plate) 1 is composed of the steel plate 23 and the GRC 24 filled therein, the thickness can be made sufficiently thin and the weight can be reduced. Further, its strength can be sufficiently strong. Therefore, the handling becomes easy, and the transportability and the construction workability can be improved. Also, since the top plate 1 is light, after the network installation work,
It is possible to easily remove the top plate 1 to easily change the layout of the network installed inside the panel. Therefore, its practical advantages are enormous. Furthermore, since the panel plate can be manufactured at a low cost, there are advantages such as great economic advantages.

Further, in this structure, since the stepped portions provided on the upper surface plate 1 and the lower surface plate 4 form the space portion in which the electrical components 13 can be incorporated, it is not necessary to unnecessarily elevate the upper stepped portions. , There is an advantage that the press working can be easily performed.

The present invention is not limited to the above embodiment. For example, the size of the panel plate and the height of the stepped portion may be determined according to the specifications. Further, the type of the steel plate 23 that constitutes the panel plate and the molded body 24 that fills the steel plate 23 are not limited to the above-described embodiments. That is, instead of the graph fiber mixed in GRC, a composite cement material mixed with inexpensive carbon fiber or other organic or inorganic molded body can be appropriately used. Further, here, an example of configuring the free access floor has been described, but the wall surface and the ceiling surface can be configured similarly. Further, if a material having a good heat dissipation property is used as a material for forming the panel plate, the heat from the electric component 13 can be effectively removed, which has a great practical advantage. In short, the present invention can be variously modified and implemented without departing from the scope of the invention.
