Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a highly practical panel that allows easy installation of network cables and their electrical components, and that can sufficiently cope with layout changes. .

[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, 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 equipment such as couplers, transceivers, modems, etc. are placed near the main cable, and electrical equipment such as couplers, transceivers, modems, etc. A drop-in cable is led out to connect office automation equipment. This prevents the entire network from going down 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 components mentioned above, as well as increase the power capacity and 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 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 raised floor is 30-45cm
□ Floor panel 15 to 30 cm from the floor (slab)
The plan is to install the floor panel so that it is raised to a certain degree, and to lay signal cables, power cables, etc. between the floor 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. 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 office layout specifications, but in reality, the above-mentioned layout is often changed, and large-scale installation work is required each time. In addition, this construction work is subject to strict legal constraints specified by the electrical equipment technical standards mentioned above, so it has not been possible to easily change the layout.

[Purpose of the invention]

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

[Summary of the invention]

The present invention makes it possible to arrange cables and electrical equipment between a first panel board that is supported on a base via a support and constitutes a floor, wall, or ceiling surface, and the first panel board. and a second panel board provided on the support column, forming a first space where the power cables can be installed, and a second space between which the power cables can be installed. In particular, a first member to which the support column is attached to the base body, and a second member which supports the second panel plate and which is attached to the first member in a position adjusted manner and which has a height of the second space portion. a third member that supports the first panel board and is attached to the second member in a position adjusted manner to define the height of the first space; It is characterized by being configured by.

〔Effect of the invention〕

Thus, according to the present invention, for example, the lower space (second space) between the second panel board of the floor constituted by a plurality of panels installed on the slab and the floor surface is utilized. The power system cables can be laid out using the power cable, and the signal cable and its electrical components can be laid out using the upper space (first space) between the first panel board and the second panel board. Therefore, it becomes possible to separate the signal system and the power system from each other. As a result, it becomes possible to easily and easily change the network equipment in accordance with the layout change while satisfying legal restrictions. Therefore, great practical effects can be achieved, such as ensuring sufficient network reliability.

Moreover, in particular, as described above, the support column is constituted by the first to third members whose positions are adjustable with respect to each other, and the support positions (heights with respect to the base body) of the first and second panel plates with respect to the base body are variably set. Since the sizes of the first and second spaces can be changed, the degree of freedom for electrical equipment and cables provided in the first and second spaces increases, and it is possible to improve the adaptability. It becomes possible. In some cases, the first and second spaces may be narrowed to a necessary and sufficient extent to reduce the feeling of pressure caused by the panel arrangement, which has the effect of increasing the degree of freedom. be given

[Embodiments of the invention]

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

FIG. 1 is an exploded perspective view of a panel according to an embodiment in which the present invention is applied to a floor panel, and FIG. 2 is a diagram showing its side structure. A top plate 1 as a first panel plate is composed of a plate main body 2 and a surface material 3 applied to the surface thereof. This top plate 1 is set to a size of, for example, 450 (mm) x 450 (mm) in consideration of workability, transportability, etc. The plate main body 2 is a calcium silicate plate, which will be described in detail later. , particle board, honeycomb structure board, composite cement material, etc., 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 may be selected depending on the use and purpose.

On the other hand, reference numeral 4 in the figure denotes 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 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.

Therefore, these upper surface plate 1 and lower surface plate 4 are
For example, four pillars 6 (6a, 6b, 6
c, 6d), they are supported in parallel with a predetermined gap between them. The main bodies of 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 top plate 1 are each fixed on the pedestal 7, and an upper space with a height of 35 (mm), 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. This leg portion 8 is connected to the bottom plate 4
The amount of protrusion is adjusted so that it protrudes downward and comes into contact with the floor surface (slab) 9. In this way, each support column 6 is constituted by three members and is provided on the floor surface 9 while 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 of 15 (mm), for example, is formed between the lower surface plate 4 and the floor surface 9, in which a power system cable can be placed. The support column 6 supporting the top plate 1 and the bottom plate 4 in this manner is constructed of, for example, cast iron, aluminum, or the like, or ceramic, synthetic resin, or the like having excellent insulation and economic efficiency.

The thus constructed floor panels are laid on the floor surface 9 of an office by abutting the ends of the top plates 1 of the plurality of floor panels against each other, for example, as shown in FIG. 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 take-out jig 11 and the like are attached using cut-out recesses provided at the ends of the top plate 1, as will be described later. 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 a coaxial cable is laid, and if necessary, a coupler, transceiver, modem, etc. An electrical component 13 is attached using the hole 5 provided in the bottom plate 4. and,
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, the signal cable 1 is provided in the lower space formed between the lower surface plate 4 and the floor surface 9.
A power system cable 15 is laid separately from the second and other cables. 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 1 as appropriate.

Thus, according to the free access floor configured by this panel in this way, the signal system and the power system can be installed independently in the upper and lower spaces separated by the bottom plate 4. become. Moreover, it is possible to configure a network that satisfies various legal restrictions. Therefore, in general, installation work for signal systems consisting of low-current circuits should be easily carried out by office workers according to the layout specifications, without outsourcing to specialized construction workers as required by law. becomes possible. In addition, as the signal system and power system are separated by the bottom plate 4 as described above, regulations such as the need to adopt a shield structure for signal system cables and electrical components, and to use grounding work are required. Since the above restrictions are eliminated, it becomes possible to significantly simplify the signal system and reduce its cost. In addition, since the electrical components 13 and the like 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., and the network Reliability can be maintained at a sufficiently high level. Furthermore, construction work associated with changing the network layout can be easily carried out by simply removing the top plate 1. Moreover, since the cables can be taken out from any position on a floor panel basis, it is possible to fully cope with layout changes that involve moving office automation equipment. Furthermore, as a secondary feature, all cables and electrical 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 the installation work of power system cables still needs to be carried out by a specialist contractor according to the law, which is a factor that hinders the above-mentioned layout change. Become. Therefore, if power outlets are attached to the bottom plate 4 at key points in advance during the initial installation of power system cables, there is no need to perform power system work when changing the network layout. Therefore, if you do this,
There will be no obstacles to network changes, and this will bring about great practical effects.

The legs 8 provided on the pillars 6 of the floor panel are used to adjust the height of the top plate 1 with respect to the floor 9 and form a uniform floor surface. It goes without saying that if the construction work is sufficiently carried out, the height of each leg 8 can be made sufficiently low, and the entire floor surface can be made low. Furthermore, here,
Although four pillars 6 are provided for each floor panel, the pillar structure may be strengthened by adding additional pillars to the center of the panel.

By the way, the upper surface plate 1 constituting the floor panel having the above structure is preferably configured as follows.

4a and 5b and 5a and 5b respectively show structural examples of the top plate 1, in which a is a partially cutaway plan view and b is a vertical sectional view thereof. Generally, the load strength of an office is 300 (Kg/m ² ), and unlike a computer room, a strength of more than (1000 Kg/m ² ) 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, when constructing the top plate 1, it is necessary to fully consider these requirements.

In the structure shown in FIGS. 4a and 4b, a honeycomb structure 21 made of asbestos, aluminum, etc. is sandwiched between synthetic resin plates such as Bakelite or aluminum plates 22 to form the top plate 1, especially this plate body 2. be. However, reinforcing materials 23 made of synthetic resin or the like are embedded in the four corners of the lever plate main body 2, that is, at the joints with the pillars 6, since the load applied to the floor panel is concentratedly applied thereto. By constructing the plate main body 2 using such a honeycomb structure 21, the load strength per thickness can be made sufficiently high. In addition, it can be made lightweight, nonflammable, and highly insulating.
The cost can also be kept low. Further, a packing material 24 having an "L"-shaped cross section and a hollow portion formed at the bent portion is pasted to each side end portion of the plate main body 2. This packing material 24 seals the gap between each top panel 1 when the top panels 1 of the floor panel are butted against each other to form a floor, and the above-mentioned sealing effect is achieved by the elastic deformation of the hollow portion. It has become possible to present it effectively. Incidentally, instead of the packing material 24 having such a structure, a packing material having a concave portion on one top plate 1 and a convex portion on the other top plate 1 is provided, and a sealing effect is achieved by fitting them together. It may be made to present. Further, it is also possible to form such a concavo-convex portion on the end portion itself of the top plate 1. With this structure, there is no risk of water entering the upper space where the signal cable 12, etc. is laid, when cleaning the floor or accidentally spilling water, and the effective waterproofing effect can be maintained. It becomes possible to obtain.

Further, FIGS. 5a and 5b show an upper surface plate 1 (plate main body 2) having a structure in which a composite cement material 26 mixed with glass fiber is used and a foamed polystyrene body 27 is embedded therein. Such composite cement material 2
6 is also useful as a component of the top plate 1 because it has excellent load strength per thickness, is nonflammable, has insulation properties, is free from pollution during manufacturing, and is inexpensive. Furthermore, if the above-described packing material 24 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 the edges from chipping. Further, the styrofoam material 27 buried in the composite cement material 26 is
This is to prevent so-called warping, but it also has a soundproofing effect, which has a great advantage. Further, this structure can be easily manufactured by molding, and the ribs can be easily made, so that the load strength by the ribs can be effectively increased.

The above-mentioned panel is an example in which four pillars 6 are provided at the four corners to support the top plate 1 and the bottom plate 4, respectively, but as shown in FIGS. 6 and 7, A plurality of floor panels arranged on a floor panel 9 are treated as a group, and for example, four upper panels 1 and four lower panels 4 whose four corners are butted against each other are designated as one group.
Support column 6 is used to simultaneously support these as a unit.
may be provided. In this case, the first
A leg portion 8, which is a member of Adjust the position against. Then, the upper surface plate 1 and the lower surface plate 4 may be respectively installed on each of these members whose positions have been adjusted.

By the way, the above-mentioned support column 6 consisting of three height-adjustable members is specifically shown in FIGS. 8a and 8b, for example.
It is configured as shown in . That is, the support column 6 includes a first member 31 as a leg portion 8 fixed to the floor surface 9, a second member 32 as a support body that fixedly supports the lower surface plate 4, and a second member 32 that fixedly supports the upper surface plate 1. A third member 33 serving as a pedestal 7 is also included. The first member 31 has a cylindrical body 36 fixed to a floor fixing member 34 with a screw 35 carved inside, and the second member 32 is screwed onto the screw 35. It's getting old. This second member 32 consists of two coaxially provided cylindrical bodies 37, 3.
8, and has a shape in which a flange 39 for attaching the lower plate 4 is protruded from the outer cylindrical body 37. A screw 40 is carved on the outer peripheral surface of the inner cylindrical body 38 to be screwed into the screw 35. The height between the first and second members 31 and 32, that is, the height of the lower space (second space) mentioned above, is adjusted by the thread amount of these screws 35 and 40. It's getting old. Further, a locking resin ring 41 is fitted between the screws 35 and 40, and this allows the second
The member 32 is designed so that it will not move due to undesired force.

Further, the third member 33 has a so-called bolt shape, and has a structure in which the pedestal 7 is provided at the head thereof. This third member 33 is similar to the second member 3
A screw 42 provided on the inner wall surface of the inner cylindrical body 38 of No. 2
The height is adjusted by screwing into the locking ring, and the locking resin ring 43 fitted therein also prevents involuntary movement.
By adjusting the position of this third member 33,
The height of the above-mentioned upper space (first space) cannot be adjusted.

Therefore, the support column 6 of the above structure is connected to the second member 32.
is for the first member 31 and for the third member 33
are each independently adjusted in height with respect to the second member 32. As a result, the sizes of the first space and the second space are set independently. Therefore, it becomes possible to appropriately set the size of the space according to the cables and electrical equipment arranged in each space, and the degree of freedom is dramatically improved. In other words, restrictions on the size of components accommodated in the first and second spaces are significantly relaxed, and compatibility with cables and electrical components can be improved.

In this way, the present invention comprises three members that can independently adjust the positions of the first and second panels to support the first and second panels. It has great effects such as expanding the flexibility of installation, and also has high practicality because of its simple structure.

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. Moreover, the top plate 1 includes the signal system electrical components 13.
It can be effectively accommodated in a properly adjusted upper cavity between the upper surface plate 4 and the lower surface 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, and can be implemented with various modifications depending on the specifications. For example, if the floor has a soundproof structure or a heat insulating structure, a soundproofing material or a heat insulating material may be appropriately inserted into the upper space or the lower space. Further, a sheet-like soundproofing material or heat insulating material may be sandwiched between the plate main body 2 and the surface material 3 of the top plate 1 to form a so-called sanderch structure.

In addition, signal cables laid in the upper space formed between the upper surface plate 1 and the lower surface plate 4 of the panel as described above and signal wires from electrical components can be taken out, and between the above-mentioned lower surface plate 4 and the floor surface 9. Electric power can be taken out from the power system cable laid in the lower space of the building as follows. That is, a recessed notch 41 is provided at the end of the top plate 1 as shown in FIG. 9, and a cable extraction jig 42 (11) and a power outlet 43 as shown in FIGS. All you have to do is fit it in. If it is not necessary to take these out, a blind plate 44 as shown in FIG. 10c may be fitted into the cutout 41. Here, the cable extraction jig 42 is
For example, it consists of two members 42a and 42b that divide the cable insertion hole 45 into two, and these members 42a,
At 42b, the signal cable 12, etc. is inserted into the insertion hole 45.
It's starting to get caught up in the. This jig 42 is designed to protrude from the upper surface of the top plate 1 by a predetermined height, thereby preventing water from entering through the insertion hole 45 during floor cleaning, etc. It's summery.

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, power can be supplied to the electrical components 13 provided in the upper space by providing a recess 46 at the end of the bottom plate 4 as shown in FIG. All you have to do is install it. This allows the mounting position of the electrical component 13 to be changed relatively easily.

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. Furthermore, the upper surface plate 1 and the lower surface plate 4
The connection structure between the support 6 and the support 6 is also not particularly limited. 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. 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 short, the present invention can be implemented with various modifications without departing from the gist thereof.
