Description

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

[Technical background of Seimei and its problems].

BACKGROUND OF THE INVENTION In recent years, efforts have been focused on the development of local area networks for interconnecting multiple office automation devices against the backdrop of significant technological innovations in microelectronic technology. This local area network is a system that 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. be.

By the way, in this kind of local area network,
Trunk cables such as coaxial cables and optical fibers are strung vertically and horizontally throughout an office, and data is transmitted via these trunk cables.

Therefore, in order to prevent accidents such as cable cutting caused by sudden repositioning of office automation equipment, etc.
Electrical equipment such as a cable, a transceiver, and a modem are arranged near the main cable, and a lead-in cable is led out from these electrical equipment to connect 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 signal cables and electrical components described above, as well as increase the power capacity and the number of electrical 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 will have a floor panel with an opening of 130 to 45 crn raised approximately 15 to 30 crn from the floor surface (slab), and signal cables, electric power cables, etc. will be laid between the floor panel 4 and the slab. It is something. 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 is applied to the electrical equipment, which may cause damage to the electrical equipment, or even cause an accident where the electrical equipment and the power cable come into contact with each other. For this reason, strict legal restrictions such as electrical equipment standards are imposed on the installation work.

In addition, this type of local area network is newly installed according to the layout specifications of the office, but in reality, the above-mentioned layout has to be changed frequently, and each time, a large amount of costly installation work is required. 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.

[Purpose of the invention]

. The present invention was made in consideration of these circumstances, and
The purpose is to facilitate the installation of signal cables and electrical components for a local area network that interconnects multiple office automation devices, as well as power cables, and to provide sufficient space for changing office layouts. It is an object of the present invention to provide a panel for IJ access that is highly practical and can be handled.

[Summary of the invention]

The present invention provides a first channel plate supported on a base via a support to constitute a floor surface, a wall surface, or a ceiling surface;
A first space portion is formed between the no-R flannel plate and the base body to allow cables and electrical equipment to be placed therein, and a second space portion is formed between the base body and the base body to allow the placement of electric power cables. A second main flannel plate is provided between the plurality of supports to form a space, especially the second one. By making the flannel plate strong enough to withstand the tension applied between the plurality of columns, the plurality of columns can be integrally supported by the second panel plate. At the same time, the second above? A recessed space is formed in the flannel board so that it is possible to step on the foot or insert the hand, thereby creating a second 1?
It is possible to work in the second space without removing the flannel plate. It's something.

〔Effect of the invention〕

Thus, according to the present invention, power system cables can be laid out by utilizing the lower space between the floor surface and the second 74 panel board of the floor, which is formed by a plurality of panels installed on the flange, for example. In addition, the signal cable and its electrical components can be placed using the upper space between the first panel board and the second four-panel board, so the signal system and power system can be interconnected. It becomes possible to separate. As a result, it becomes possible to easily and easily change the network equipment accompanying the layout change while satisfying legal restrictions. Therefore, great practical effects such as sufficient network reliability can be achieved. Furthermore, since the columns supporting the first and second mother panel plates are mutually integrally supported by the second panel plate having sufficient tensile strength, each column is placed on the base body. It is possible to ensure sufficient overall d'-nel surface strength even without fixing to. Therefore, not only the installation work is greatly simplified, but also
The durability against earthquakes and the like can be made sufficiently high. In addition, in this way, the second flannel plate and the pillar cooperate with each other to make it strong. Since the flannel structure is stored, the first
By simply removing the panel board locally, and by utilizing the space provided in the second panel board, great effects can be achieved, such as the ability to easily work on the inside of the panel board.

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 the side structure of the main part thereof. The top plate 1 as a first flannel plate is composed of a plate body 2 and a surface material 3 applied to the surface thereof. This top plate 1 is made of, for example, 450 mm in consideration of workability, transportability, etc.
The board body 2 is a calcium silicate board, which will be described in detail later.

It is constructed using various materials such as particle pods, honeycomb structure plates, and composite cement materials. At this time, the load capacity required for the top plate 1.

Needless to say, the constituent materials are selected with consideration to weight, thickness, insulation, fire resistance, economic efficiency, etc. Further, as the surface material 3, so-called vinyl tiles, carpets, jutetan, etc. are used, and these may be selected depending on the use and purpose.

On the other hand, numeral 4 in the figure represents 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 the shape of an IJ sock 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, the lower surface plate 1 and the lower surface plate 4 are used as a floor surface (slab).
It is provided on top to form a floor surface.

The pillar 6 is attached to the slab 1 as shown in FIG.
It consists of a first member 8 which is appropriately fixed to the first member 8, and a second member 9 whose height is adjusted by screwing into a screw mechanism provided on the first member 8. For example, a part of the corner of the lower plate 4 is attached to the flange IQ provided at the intermediate portion of the first member 8 of this support 6? The mounting is secured by nuts.

Further, the upper plate 1 is fixed to a pedestal portion 11 of a second member 9 which is provided on the first member 8 in a height-adjustable manner. The height of the first space formed between the upper surface plate 1 and the lower surface plate 4 is adjusted by adjusting the height of the first member 8 and the second member 9 using the screw mechanism, for example, for electrical equipment. It is set to about j) 35+m to the extent that it can be installed. Incidentally, the height of the flange 10 relative to the slurry f7 may also be adjustable. The lower space of the lower plate 4 is set to a height of approximately 15III+11 in order to enable the installation of power cables. The pillars 6 having such a structure support the front upper plate 1 and the lower plate 4, respectively, which are arranged with their four corners abutted against each other, thereby achieving the above-mentioned 4. The upper plate 1 and the lower plate 4 are connected to each other.

By the way, the above-mentioned top plate 1. Specifically, each part of the z and flannel of this embodiment, which includes the bottom plate 4 and the support column 6, is constructed as follows. Fig. 3 (,) (b) and Fig. 4 (,) (b) show an example of the structure of the top plate 1, in which (11) is a partially cutaway plan view, and (b) is its vertical cross-section. It is a diagram. Generally, the packing strength of an office is 300 (
Kg/m2) and 1
000 (Kg/m2) or more 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.

310(a) and 310(b), a honeycomb structure 21 made of asbestos, aluminum, etc. is sandwiched between synthetic resin plates such as Bake 2ite or aluminum plates 22, and the upper plate 1, especially this, is attached to the plate body. 2.

However, reinforcing materials 23 made of synthetic resin or the like are embedded in the four corners of the lever plate main body 20, that is, at the joints with the pillars 6, since the load applied to the floor/channel is concentrated. By constructing the plate main body 2 using such a honeycomb structure 21, the load strength of the thickness support can be made sufficiently high. Moreover, it can be made lightweight, nonflammable, and highly insulating, and its cost can be kept low. Also, this board body 2
A backing material 24 having an rLJ-shaped cross section and a hollow portion formed at the bent portion is attached to each side end portion of the backing material 24 . This flat and king material 24 is formed by abutting the top plates 1 of the floor panel against each other to form a floor, and each top plate 1
The sealing function is effectively exerted by the elastic deformation of the hollow portion. In addition, in place of such a structure and the king material 24, a backing material having a concave portion on the top plate 1 and a convex portion on the other top plate 1 is provided, and by fitting these backing materials, sealing is achieved. It may be made to exhibit an effect. Further, it is also possible to form such a concave and convex portion on the end of the top plate 1 itself. If the structure is like this,
When cleaning the floor or accidentally spilling water, there is no risk of water entering into the upper space where the signal cable 12 etc. are laid, and an effective waterproofing effect can be obtained.

In addition, FIG. 4(,), (Xun) shows the top plate 1 (plate main body 2) of a structure using a composite cement material 26 mixed with glass fiber and having a Styrofoam body 27 embedded therein. The composite cement material 26 is also useful as a constituent material of the top plate 1 because it has excellent load strength in terms of thickness, is nonflammable, has insulating properties, and is inexpensive with no risk of pollution during manufacturing. Also, if the top plate 1 having such a structure is provided with the packing material 24t as described above, it is convenient in practice not only to provide a waterproof effect but also to prevent the edges from chipping. Also, the styrofoam material 2 embedded in the composite cement material 26
7 is for preventing the above-mentioned composite cement material 260 from collapsing, but it also provides a soundproofing effect, which is a great advantage. Further, this structure can be easily manufactured by casting and porcelain molding, and the ribs can be easily made, so that the load strength by the ribs can be effectively increased. In this way, the top plate 1 has a structure that satisfies the specifications required for flannel and flannel and can be easily manufactured.

On the other hand, the lower plate 4 is constructed as shown in FIG. The lower plate 4 is made of a non-combustible and insulating material such as a vinyl steel plate, and has a shape such that its four corners are connected to the flanges 10 of the support column 6, respectively.

Therefore, the lower plate 4 has sufficient strength to withstand the tensile force applied between the columns 6 connected to each of the four corners. A recess 28 is provided on each side connecting the four corners, and a space through which one can step into the slab 7 is formed.

This space also plays a role in facilitating the work on the power cables arranged in the lower space of the bottom plate 4. Furthermore, each edge of this bottom plate 4 is bent to have strength 751 against bending force,
In addition, the bending of the edges prevents accidents such as peeling off of the coating on the power cables.

Thus, by arranging the upper plate 1 and the lower plate 4 as described above on the slab 7 via the supports 6, a floor surface consisting of the upper plate J can be formed on the slab 7 as shown in FIG. . A surface consisting of a lower plate 4 which forms a first space between it and the upper plate 1 and a second space between it and the slurry 27 to interconnect each support column 6. can be configured. At this time, a cable removal jig 3 is provided at the end abutment location of the top plate 1 as required. The cable removal jig 3 and the like are attached using four notches provided at the end of the top plate 1, as will be described later. In the upper space formed between the upper panel 1 and the lower panel 4, a network trunk cable 12 such as an optical fiber or coaxial cable is laid, and if necessary, a coupler, trunk coupler, modem, etc. Electrical components 13 are attached using holes 5 provided in the bottom plate 4. A lead-in cable 14 from this electrical component 13 is taken out through the jig 1 to the upper surface of the top plate 1, the shim floor surface, 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, a power system cable 15 is installed separately from the signal cable 12 and the like. A power outlet and the like drawn out from the power system cable 15 are provided on the bottom plate 4 and the top plate 1 as appropriate.

For example, when taking out signal cables laid in the upper space formed between the upper surface plate 1 and the lower surface plate 4 of the panel and signal lines from electrical components, the lower surface space between the lower surface plate 4 and the floor surface 9 is The power extraction from the power system cable laid in the place is 11
This is done as follows. That is, the seventh
If a recessed notch 41 is provided as shown in Fig. 8, and a cable extraction jig 42 (31) and a power outlet 43 as shown in Figs. 8(a) and 8(b) are fitted into this notch 41. In addition, if it is not necessary to take out these cables, a blind plate 44 as shown in FIG. 8(C) may be fitted into the notch 41. For example, if the cable insertion hole 45 is
The signal cable 12 and the like are inserted into the insertion hole 46 by the two separating members 42m and 42b. This jig 42 protrudes 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. ing.

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, the power supply to the electrical equipment 13 installed in the upper space is as follows.
For example, as shown in FIG. 9, a recess 46 may be provided at the end of the bottom plate 4, and a power outlet 47 as shown in FIG. 10 may be attached to this recess 46. Thereby, the mounting position of the electrical component 13 can be changed relatively easily.

Using such parts as appropriate, the above-mentioned 13 types of electrical components and 12 types of cables can be placed in the upper space (first space) of the bottom plate 4.
In addition, power system cables 15 are provided in the lower space (second space) to construct a local area network.

Thus, according to the free access floor configured by the present panels 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. can. Furthermore, 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 can be easily carried out by office workers according to the layout specifications, without having to entrust it to specialized construction workers as stipulated by law. It becomes possible. In addition, as the signal system and power system are separated by the bottom plate 4 as described above, it is necessary to adopt a shield structure for the signal system cables and electrical components, and to use grounding work, etc., according to laws and regulations. Since there are no restrictions, it becomes possible to significantly simplify the signal system 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. Furthermore, construction work associated with changing the network layout can be easily carried out by simply removing the top plate 1. Furthermore, since the cables can be taken out from any desired position on a floor panel basis, it is possible to fully cope with changes in the layout associated with the movement of 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 of signal cables can be easily carried out, but the installation of power cables is legally required to be carried out by a professional engineer, and the above-mentioned layout changes are required. It becomes a factor that hinders. Therefore, if power outlets are attached to the bottom plate 4 at important points in advance during the initial installation of the power system cables, there is no need to perform power system work when changing the network layout. Therefore, if this is done, there will be no impediments to changes in the network, and a great practical effect will be achieved.

Furthermore, the screw mechanism provided on the column 6 of the floor panel is used to adjust the height of the top plate 1 with respect to the slab 7 and form a uniform floor surface. It goes without saying that if the height of each leg section 8 is sufficiently low, the height of each leg section 8 can be made sufficiently low, and the entire floor surface can be lowered.

Furthermore, according to the present invention, a structure is constructed in which the lower plate 4 has sufficient strength to withstand the tension between the columns 6, and the columns 6 are integrally supported, so that, for example, as shown in FIG. As shown in , even if only the pillar 6 at a specific position (indicated by a * mark) is fixed to the slab 7 and the other pillars 6 (indicated by a 0 mark) are simply placed on the slab 2, The columns 6 form a structure that is strongly connected to each other via the lower plate 4. In other words, since the bottom plate 4 strongly supports each support column 6 to form a single structure, a floor with high strength against earthquakes and the like can be realized. Further, since it is not necessary to fix all the supports 6 to the slab 7 as described above, effects such as a significant reduction in installation cost can also be achieved. Furthermore, as mentioned above, the recess 2 provided in the bottom plate 4
8 can be used effectively to carry out various types of construction work, which can also be effective in making the work easier. In other words, the bottom plate 4
Since work can be done on the electric cables 15 without removing them, and work can be easily done on the electrical components etc. arranged on the bottom plate 4, it is possible to sufficiently deal with changes in the layout of the system, etc. is played.

Note that the present invention is not limited to the embodiments described above. For example, although the explanation has been given using a floor panel as an example, it is possible to similarly configure a wall panel or a ceiling panel. In addition, the structure of the top plate 1 and the structure of the support column 6 may be determined according to the specifications.
It is also possible to embed soundproofing material as appropriate. Moreover, the pillar 6
The connection/support structure of the upper surface plate and the lower surface plate is also not particularly limited. 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 panel plates. 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.

As described above, according to the present invention, it is possible to construct a panel surface that is simple and has excellent strength. For example, when constructing a local area network, the signal system and the power system can be separated, and the panel surface can be easily constructed. Can perform cable installation. Moreover, the electrical components 13f, including the signal system, can be accommodated in the upper space between the upper plate 1 and the lower plate 4. Therefore, network 4
You can organize everything in one place and improve the aesthetics of your office. 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.
