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]

BACKGROUND OF THE INVENTION In recent years, efforts have been focused on the development of local area networks that interconnect multiple office automation-like devices due to significant technological innovations in microelectronic technology. This local area network performs data communication at a high speed of, for example, 10 Mbps between a plurality of workstations, large-capacity file devices, printer devices, etc. via transmission cables made of coaxial cables, optical fibers, and the like.

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. Conventionally, in order to prevent cable disconnection accidents caused by moving office automation equipment, electrical components such as couplers, transceivers, modems, etc. are placed near the main cable, and drop-in cables are routed from these electrical components. and 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 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 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 consists of a floor panel with a -side of 30 to 45 υ, 15 to 30 cm from the floor (slab)! i! It is intended that signal cables, electric power cables, etc., be laid between the panel and the slab.

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, the installation of this type of local area network is carried out according to the office layout specifications,
In reality, there were many changes to the layout after the above construction work, and each time required manual changes. Moreover, 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.

Therefore, the present inventors previously proposed a panel having the following structure in Japanese Patent Application No. 885B-83619. 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. 1st
The top board 1 as a panel board consists of a board main body 2 and a surface material affixed to its surface.
The board body 2 is made of various materials such as calcium silicate board, particle board, honeycomb structure board, and composite cement material. It is configured by using it as appropriate.

At this time, the load resistance, weight, thickness, and
Needless to say, the constituent materials are selected with consideration to insulation, fire resistance, economic efficiency, etc.

Further, as the surface material 3, so-called vinyl tiles, carpets, jutetan, 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 arranged in a matrix for fixing electrical components as necessary. This bottom plate 4
As will be described later, space is provided between the top plate 1 and the floor surface (slab) 9 that is the base body for the signal cables and electrical components that constitute the network, and the space for the power system cables. It is formed by separating the

These upper plate 1 and lower plate 4 are supported in parallel on the floor surface 9 by four pillars 6 (6a, 6b16c16d) with a predetermined (7) gap between them.

The pillars 6 are fixed to each of the four corners of the bottom plate 4,
A pedestal 1 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 placed. 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, a cable extraction jig 11 is provided at the end abutment location of the side plate 1, if necessary. 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
can be removed using the hole 5 provided in the bottom plate 4. 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 or t-1-mation equipment. Further, a power system cable 15 is laid in a second space formed between the bottom plate 4 and the floor 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 lower surface plate 4'' or the upper surface plate 1 as appropriate, and power is supplied to the electrical components 13 and office automation equipment through this power outlet.

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 simply done by office workers according to the layout specifications, without having to entrust it to a specialist or expert contractor as required by law. You can do this in In addition, since the signal system and the power system are separated by the bottom plate 4, there are restrictions such as having to use a shield structure or a grounding structure for the signal cables and electric power (equipment). This makes it possible to greatly simplify the signal system and reduce its cost.Furthermore, by simply removing the top plate 1, the construction work associated with changing the network layerer 1 can be done on a panel-by-panel basis, and can be done at any time. Since this can be done from the location of , it is possible to easily change specifications such as the network layout i-.

However, in the panel having the above structure, the first and second spaces occupy a large space. Therefore, the Ministry of the Invention, etc. has developed the fourth panel as a panel with a structure that eliminates such defects.
A panel with the structure shown in the figure was proposed. This panel has a structure in which the bottom plate (second panel plate) 4 is formed by pressing, for example, a vinyl steel plate whose surface is insulated and has a stepped portion.

That is, the second panel board is provided with a stepped portion on its main panel surface 4a, forming a corner duct portion 4b and an edge duct portion 4C, respectively. The corner dow portions 1 to 4b form steps at their four corners with a height equal to or smaller than the main surface 4a, and the edge duct portion 4C has a height h2 (<hl) at its edge relative to the main surface 4a. They are each provided by forming a step.

In particular, the edge duct portion 4C is provided parallel to the side of the panel, and the corner duct portion 4b is provided with a step formed in the so-called chamfering direction at an angle of 45° with respect to the corner. Note that the pillars 6 are attached to these step portions, that is, the corner duct portion 4b and the edge duct portion 4C.
A hole 21 for coupling with the cable and a knock part 22 which can be cut out as required are provided, and when the knock piece is removed, a hole or recess 23 is formed through which cables can be inserted. ing. A rubber bushing 24 is attached to the edge of the recess 23 formed by removing the knock piece to prevent accidents such as peeling off of the cable coating due to the cutting edge of the cables inserted there. ing. Incidentally, instead of such a lock portion 22,
The recess 23 may be formed in advance in the edge duct portion 4c, and the recess 23 may be closed off with a so-called blind plate when not in use.

On the other hand, the first and second panel plates (top plate, bottom plate) 1
．． The pillars 6 supporting each of the 2 are a lower punch 6a fixed to a base (floor surface, slab) 9, an upper plate 6b attached to the lower plate 6a with height adjustment, and a lower punch 6b fitted on the upper plate 6b. It is constituted by a pedestal 6C made of a hard rubber material and fitted together. The height of the upper plate 6b is adjusted by screwing a bolt into a screw (nut body) protruding from the center of the lower plate 6a. The first and second panel plates 4.1 are supported by fitting into the projections 27 of the pedestal 6C provided on the height-adjusted upper plate 6b.

By configuring the second panel board 4 in this manner, the limited space between the first panel board 1 and the floor surface 9 can be effectively separated by the stepped portion of the second panel board 4. Thus, the first and second spaces can be formed respectively. The height of the first panel board relative to the floor surface 9 can be kept low to form a sufficient first space between which electrical components 13 can be installed. A second space can be formed around the periphery.

However, in such a structure, the second panel board 4
Since the supporting columns 6 are located at each of the four corners of the second panel board 4 and are fixed to the floor surface 9, there is a problem in that they interfere with the installation of power system cables. In other words,
Since the pillars 6 are fixed to the floor surface 9 and provided at each intersection of the second space portion formed in a lattice shape by the second panel board, this becomes an obstacle to the installation of power system cables.

[Purpose of the invention]

The present invention has been made in consideration of the above circumstances, and its purpose is to further improve the structure of the panel described above to provide a second space portion that facilitates the installation of power system cables. Our goal is to provide highly practical panels that can be used to create

It is characterized by being constructed from plates.

〔Effect of the invention〕

Thus, according to the present invention, the lower plate of the support has a structure that integrally forms the first and second space parts integrally with the second panel plate, and the edges thereof are bent by, for example, press molding so as to be attached to the base. Since the window part is fixed, there is no undesirable so-called protrusion between the lower plate and the base.
A space can be formed. Therefore, it not only has the advantages of the previously proposed panel structure, but also has tremendous effects such as being able to effectively form a second space that allows power system cables to be laid easily.

[Embodiment of the Invention] “Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 5 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 the second panel board 4
and pillar 6. The second panel board 4 has a structure in which corner ducts 4b at its four corners are cut off, and only a portion 4C of the edge duct 1 is formed on its four sides. The cut-off corner duct portion 4b is supplemented by a lower plate of the support column 6, which will be described later.

Therefore, the lower plate 6X of the support column 6 has its edge bent downward by, for example, press processing to form a step that is fixed to the base 9, and the duct opening 6y is formed on the side between the steps. is formed.

The end of the edge duct portion 22, which is a stepped portion of the second panel plate 4, is placed and fixed at the end of this opening 6y, and the second panel plate 4 and the lower plate 6x are integrated by wear. Ru. At this time, the stepped portion of the lower plate 6x fits into the cut-off corner duct portion, and the first
and one surface that separates and forms the second space are integrally formed. In this state, a second space is formed between the main surface of the lower plate 6x and the floor 9, which communicates with the frontage 6y and the lower space of the edge duct 22. The upper plate 6b that supports the first panel board 1 is provided on the main surface of such a lower plate 6x with its height adjusted via a screw mechanism or the like.

Figure 6 shows the second plate fixed to the lower plate 6x of the above structure.
7 shows the positional relationship between the panel board 4 and the lower plate 6X, and FIG. 7 shows its cross-sectional configuration.

Thus, as shown in these figures, according to the second panel plate 4 and the lower plate 6x of the support column 6 having the above-described structure, the stepped portion effectively acts to separate the first panel plate 1 and the second panel plate 1.
A wide first space is formed between the panel board 4 and the base plate (slab) 9, and the peripheral step part of the second panel board, the lower plate 6x of the support column 6x, and the base (slab) 9 are formed. A second space can be formed in which power system cables can be easily laid without any unwanted protrusions. In other words, since there is no protrusion at the center of the intersection of the second space, power system cables can be easily laid. Further, since the lower plate 6x of the support column 6 has a structure in which the one-step corner portion thereof is fixed to the base body 9, the ground contact area of the support support can be increased, and earthquake resistance and stability can be improved. In addition, the lower plate 6x of the above structure is
For example, it can be easily manufactured by pressing a steel plate, etc., and the manufacturing cost can be reduced. Furthermore, since the second panel plate 4 is directly attached to the lower plate 6x, it is possible to reduce the manufacturing precision of the support column 6, and other effects can be achieved.

Therefore, its practical advantages are enormous.

Note that the present invention is not limited to the embodiments described above. For example, although a case has been described here in which a free access floor is constructed using this panel, a wall surface or a ceiling surface can be constructed in between. Further, it is also possible to construct the panel in such a way that another second panel plate is provided between the first panel plate 1 and the floor surface to separate the installation space for gas pipes and water pipes. stomach. In short, the present invention
A step part is formed in the panel board to effectively separate the first and second space parts, and the lower plate of the branch supporting the second panel board is integrated with the second panel board. The present invention has a 16-step structure in which the second space can be formed separately, and can be implemented with various modifications without departing from the gist thereof.
