Description

The present invention relates to an underfloor cable wiring method for wiring various cables in an underfloor space by utilizing a double floor structure.

[Conventional technology]

Conventionally, as this type of under-floor cable wiring method, methods generally shown in FIGS. 5 to 7 are well known.

To briefly explain this, first, FIG. 5 illustrates a floor of a communication device machine room using this type of underfloor cable wiring method. In FIG. 5, 1 is the original machine room floor, Reference numeral 2 denotes a double-floor surface composed of a large number of panel plates 2a arranged at predetermined intervals on the upper part of the double-floor surface. In the underfloor space 3 formed in the double-floor portion, cables including power lines and various signal lines are provided. 4 are wired on the floor surface 1 by appropriately intersecting each other.

Here, 5 in the drawing is a panel plate 2 that constitutes the double floor surface 2.
A support leg 6a is a device housing for a communication device or the like installed in the machine room. The device housing 6 is a leg on the floor surface 1 so as to be located on the same plane as the double floor surface 2. It is supported by an apparatus fixing support base 8 supported via the section 7. Further, a portion indicated by 9 in the drawing is an intersecting portion of the cables 4 and 4 which are wired orthogonally to each other.

[Problems to be Solved by the Invention]

By the way, according to the conventional underfloor cable wiring method as described above, the vertical and horizontal cables 4 that are wired to intersect each other are provided.
(4A, 4B) are laid directly on the floor surface 1 so that the cables 4 are laid vertically in FIG.
A and 4B which are wired in the lateral direction are shown in FIG. 6 and FIG.
As is clear from the drawing, the cables are directly laminated at the cable crossing portion 9, and the following problems cannot be avoided.

That is, at the above-described cable crossing portion 9, one cable (the cable 4B in the horizontal direction in this example) is curved and routed so as to ride over the cable 4A routed in the vertical direction on the other side. Problems such as characteristic deterioration due to bending and crosstalk of 4A and generation of noise due to power supply wraparound due to inability to separate the signal line from the power line will occur.

Furthermore, although it is necessary to remove the cable 4 due to deterioration over time due to use over a long period of time, etc., it is necessary to cross the cable 4 (4A, 4B) laminated on the entire floor at the intersection 9
Therefore, it is difficult to identify the required cable 4. Also, at such an intersection 9, the cable 4
Since the frictional forces between A and 4B are large, there is a problem that it is difficult to pull out the cable 4 to remove it, and it is required to take some measures in consideration of these points.

[Means for Solving the Problems]

In order to meet such a demand, an underfloor cable wiring method according to the present invention is for wiring cables under a floor with double floors that are juxtaposed at predetermined intervals and cross each other. In order to use it as a stand, it is equipped with a support stand that is placed upright on the floor so that the device case is exposed and exposed on the double floor surface. In the middle of the vertical direction, a cable support that extends horizontally is attached and fixed, and another cable that runs in the direction orthogonal to the cable that runs directly on the floor and intersects By supporting the cable on the floor side, the cable is separated from the cable on the floor side.

[Action]

According to the present invention, when wiring the cables intersecting each other in the underfloor space of the double floor structure, one of them is directly wired to the floor surface side, and the other is the cable support body on the support base side of the apparatus housing. By supporting and wiring the cables, it is possible to separate the wiring intersections of the cables at a predetermined gap, eliminating the conventional crossing condition due to stacking, and separating the individual cables in an orderly manner. It is possible.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

1 to 4 show an embodiment of the underfloor cable wiring method according to the present invention.
The same or corresponding parts as those in FIGS. 5 to 7 described above are designated by the same reference numerals and the description thereof will be omitted.

According to the present invention, when the underfloor space 3 formed by the double floor surfaces 2 arranged side by side at a predetermined interval on the floor surface 1 is used for wiring the cables 4A and 4B that are wired to intersect each other. As shown in FIGS. 1 and 2, the apparatus casing 6 (see FIG. 5) is installed on the floor surface 1 so as to face the double floor surface 2 side, so that the double floor surface 2 can be installed. Midway in the height direction (position of height h) with respect to the leg portion 7 facing the underfloor space 3 of the plurality of support bases 8 placed and arranged so as to be exposed above.
From the cable support 11 extending in the horizontal direction from the cable support 11 is fixedly installed, and another cable 4A that is wired and intersects in a direction orthogonal to the cable 4B that is directly wired on the floor surface 1 is used as the cable support. It is characterized in that it is configured to be separated from the cable 4B on the floor surface 1 side and to be wired by being sequentially supported on the body 11.

Here, reference numeral 12 in the drawing denotes a cable that is pulled out from the cable 4A to the apparatus housing 6 side.

According to such a configuration, when the cables 4A and 4B intersecting each other are wired in the underfloor space 3 having the double floor structure, one of them (4B) is directly wired to the floor surface 1 side, and the other is (4A) is sequentially supported by the cable support 11 on the leg portion 7 side of the support base 8 of the apparatus housing 6 for wiring, so that the wiring intersections 9 of the cables 4A and 4B are separated at a predetermined gap. It becomes possible to do. Therefore, in such a configuration, the crossing state due to stacking as in the past is eliminated, and the individual cables 4A,
4B can be orderly separated and wired.

Further, according to the above-described configuration, one of the cables 4A and 4B (4A) is attached and fixed midway in the height direction of the leg portion 7 of the support base 8 that supports the apparatus housing 6, and is horizontally fixed. Since it is supported by the extended cable support 11,
When pulling the cables 4A and 4B into the apparatus housing 6, there is an advantage that the cables 4A and 4B can be pulled in easily.

This is because, for example, not only the pull-in cable 12 from the cable 4A supported by the cable support 11 on the support base 8 side but also the cable 4B routed on the floor surface 1 side is temporarily supported by the cable support 11 side. It will be easily understood that the work can be performed relatively easily by pulling in the cable 12 or the like to the device housing 6 side supported by the support base 8.

Further, since the cable support 11 is attached and fixed midway in the height direction of the leg portion 7 of the support base 8 that supports the device housing 6, positioning work of the cable support 11 during cable laying work, There is no need to perform installation work,
There are also advantages such as easy installation work.

In the underfloor space 3 having the double floor structure described above,
It is advisable to wire the intersecting wiring portions of the cables 4A and 4B, which are laid on a portion other than the vicinity of the support base 8 that supports the apparatus housing 6, for example, as shown in FIGS. 3 and 4.

To briefly explain this, reference numeral 10 indicates a horizontal direction from the middle of the height direction (at a position of height h) with respect to the plurality of support legs 5 standing from the floor surface 1 to the double floor surface 2 side. The extended cable support sequentially supports another cable 4A which is wired and intersects with the cable 4B directly routed on the floor 1 by the cable support 10 and intersects with the cable 4B. It is convenient to wire separately from the cable 4B on the side.

Here, such a cable support 10 has a double floor surface 2
It is preferable that a part of the panel plate supporting leg 5 constituting the above is hung between the supporting legs 5 and 5 adjacent to each other so that the panel plate supporting leg 5 is positioned above the floor surface 1 by an arbitrary height h and is fixedly mounted.

In this way, when wiring the cables 4A and 4B having the portions intersecting with each other in the double floor structure portion, one of them (4B) is directly wired to the floor surface 1 side and the other (4
A) can be sequentially supported by the cable support 10 on the side of the leg stud (5) for wiring, and the intersecting portion 9 can be separated and wired at a predetermined space, so that the conventional crossing state due to stacking is eliminated. However, there is an advantage that the individual cables 4A and 4B can be arranged and separated separately.

Further, according to the cable wiring method in the present embodiment as described above, the cable having the predetermined height h is provided on the leg portion 7 on the device support base 8 side and further on a part of the support leg 5 on the double floor 2 side. By the simple method of attaching the supports 11 and 10, the cables 4A and 4B that intersect with each other in the conventional underfloor cable wiring are not laminated and wired, and are separated from each other with a predetermined space. It is wired in order.

Here, one cable 4A or 4B is used as a signal line,
If the other is used as a power line, or if one cable 4A or the like, which is separately wired, is divided into a signal line and a power line and wired, the signal line and the power line are completely separated. It becomes possible.

It should be noted that the present invention is not limited to the structure of the embodiment described above, and the shape, structure, etc. of each portion can be freely modified or changed.

For example, the underfloor cable wiring method according to the present invention can be effectively applied to a machine room or the like in which a device housing 6 is installed in an information processing device such as a computer, a switchboard, or a communication device such as various transmission devices. In addition, there is no characteristic deterioration due to cable wiring, and it is possible to flexibly deal with device replacement and the like.

Further, according to the method described above, the wiring route of the cable can be arranged in an orderly manner, which is effective for a large amount of cable wiring, and is linear even for an optical fiber cable having a problem with bending or the like. Since it can be dealt with only by using the simple wiring, it is advantageous in terms of the strength guarantee.

In order to use it as a stand, it is equipped with a support stand that is placed upright on the floor so that the device case is exposed and exposed on the double floor surface. In the middle of the vertical direction, a cable support that extends horizontally is attached and fixed, and another cable that runs in the direction orthogonal to the cable that runs directly on the floor and intersects Supported by
Since it is configured to be wired separately from the cable on the floor side, the excellent effects listed below can be obtained.

That is, according to the present invention, one of the cables that intersect with each other is directly wired to the floor surface side, and the other is supported by a cable support body provided on a support base of the apparatus housing to perform wiring, whereby It is possible to separate and wire the parts in a predetermined gap, the crossing condition due to the stacking as in the related art is eliminated, and the individual cables can be separated and wired in an orderly manner.

Therefore, it is possible to solve problems such as the conventional characteristic deterioration due to cable bending, noise around power supply, and troublesome identification and removal of the cable, and flexibly deal with equipment layout changes on the floor. The advantage is that

This also has the advantage that the cable can be easily pulled in when pulling the cable into the device housing.

This is not only for pulling in from the cable supported by the cable support on the support base side, but also for the cable wired on the floor side, once it is supported on the cable support body side and then pulled in to the device housing side on the support base. It is possible and easy to understand because the work is relatively easy.

Further, according to the present invention, since the cable support is attached and fixed midway in the height direction of the support base that supports the apparatus housing, the cable support is specially positioned and installed in the work such as cable laying. There is also an advantage that there is no need to perform it and the installation work is easy.
