It is virtually divided into two areas. In each of the four areas A to D, six work desks, each of which is represented by reference numeral 11 to 16, are shown as a subscript. An information equipment terminal (not shown) such as a telephone or a computer is arranged on each of the work desks 11 to 16.

Further, one terminal board 20 corresponding to a network device is installed at a predetermined location on the floor, and between the terminal board 20 and each of the four areas A to D as shown in FIG. In addition, one wire harness 30 is laid.

The wire harness 30 will be described in detail. The wire harness 30 is configured to include tubed wires 31 each corresponding to a tube-containing line group, and four tubed wires 31 are provided corresponding to the four areas A to D. As shown in FIG. 3, each tubed wire 31 is configured by housing six 8-core multi-pair twisted pair electric wires 33 in a tube 32. In addition, in the case of the present embodiment, the multi-pair twisted pair electric wire 33 has specifications that meet the category 5 standard. Further, although not shown, an identification code (for example, A to D) indicating an area corresponding to each tube 32 of the tubed wire 31.
No. or numbers 1 to 4) are attached so that the corresponding region of each tubed wire 31 can be identified at a glance.

The wire harness 30 shown in FIG.
As shown in FIG. 3, the binding boxes 40 are provided at three positions on the way from the base end to the tip, and the four tubed wires 31 are bound in a form of being aligned in a horizontal row. The binding box 40 has a flat rectangular shape, and is divided into upper and lower halves as shown in an enlarged view in FIG. An outlet 42 is formed, and a branch outlet 43 is formed on a side surface different from these. Here, one of the three binding boxes 40 located in the middle part is shown in FIG. 4, which has three line inlets 41 and two line outlets 42. In the binding box 40, three tubed wires 31
Was introduced inside and two of them penetrated here and the line outlet 4
The other one is bent at a right angle to the extension direction of the wire harness 30 and is led out to the outside from the branch lead-out port 43. The branch outlet 4
3 has an opening shape that extends long along the extension direction of the wire harness 30 so that the binding box 40 can be moved along the extension direction of the wire harness 30.

A branching device 50 is provided at the tip of each tubed wire 31 and, for example, six modular outlets 51 are built therein, and a modular plug (not shown) from the information equipment terminal is attached to the modular outlet 51. It is supposed to be connected. It should be noted that a cable bundling member 44 having a U-shaped cross section of a cable accommodating groove is provided at a required position between the binding boxes 40 in the wire harness 30.
Is provided.

The construction procedure in this embodiment is as follows. First, according to the arrangement plan of the work desks 11A to 16D, the position of the switch 50 to be installed for each group of work desks is determined,
Depending on the position and the position of the terminal board 20, a length of 4
A type of tubed wire 31 is prepared. Four of the tubed wires 31 are arranged in parallel, and are bundled as one wire harness 30 by putting the tubed wires 31 through the binding box 40. The above work can be performed at the harness factory.

Next, the wire harness 30 manufactured as described above is carried from the harness factory to the construction site where it is laid at a predetermined position in the underfloor wiring space. The wiring space is, for example, as shown in FIG.
The floor plate 19 is spread on the pillars 18 which are erected on the upper side, so that the pillar 18 is formed between the floor plate 19 and the floor slab 17. Then, the branching device 50 is fixed to the underfloor wiring space or a predetermined position on the floor, and the core wire of each tubed wire 31 is connected to the terminal board 20. Since the laying work of the wire harness 30 is completed only by this, thereafter, all the work is completed by inserting and connecting the modular plugs from the information equipment terminals such as telephones and computers to the modular outlets 51 of the branching device 50.

According to this embodiment described above, the following effects can be obtained. First, as a wiring work at a construction site, a wire harness 30 is laid in a predetermined wiring space, each tubed wire 31 is connected to the terminal board 20, and the branching device 5 is connected.
It just fixes 0 to the required location. Therefore, the wiring work can be efficiently performed in an extremely short time, and the on-site construction cost is significantly reduced. Moreover, a large number of twisted pair electric wires are first accommodated in the tube 32 as the tubed wire 31, and the four tubed wires 31 are bundled as one wire harness 30 by the binding box 40. Since they are integrated into the compact, they can be compactly packed, and the space for accommodating the line group can be small. Therefore, unlike the conventional wiring structure in which a large number of twisted pair electric wires are directly connected directly between the terminal board and each information device terminal, a large number of lines do not become chaotic and complicated. Since the harnesses 30 are arranged in an orderly manner, it is possible to accommodate a line having a sufficient capacity even in a narrow wiring space, and space efficiency is improved.

Further, particularly in the present embodiment, the office is divided into a plurality of areas and the branching device 50 is provided for each of the areas, so that it is extremely easy to add or relocate the branching device 50 as a unit. Moreover, when repairing some wiring,
First, since the tubed wire 31 to which the wiring belongs is specified and the target electric wire in the tubed wire 31 is specified, the wiring can be easily found and maintenance / inspection work becomes easy.

Furthermore, since the binding box 40 of this embodiment can be freely moved with respect to the wire harness 30 along the extension direction thereof, the binding box 40 is obstructed depending on the condition of the wiring space under the floor. It can be moved to a position where it does not become a problem, and the flexibility in wiring work is further increased.

<Second Embodiment> FIGS. 5 to 7 show a second embodiment of the present invention. The difference from the first embodiment is the binding box 6
Since the structure is 0 and the other points are the same, the same reference numerals are given to the same portions and duplicate description will be omitted. The binding box 60 has a substantially T-shaped planar shape, and a flat plate-shaped lid 62 is fitted to a case body 61 having an open upper surface, and a line introduction port is provided on each surface facing each other in the extension direction of the wire harness 30. 63 and a line outlet 64, and a branch outlet 65 on a side different from this. In addition, the above line introduction port 6
90 between the line 3 and the line outlet 64 and the branch outlet 65.
The inner wall surface is bent in an arc shape in the angle region of degrees, and this wall surface is made to function as a bending restriction portion 66 that restricts the bending curvature of the tubed wire 31.
6 and 7, reference numeral 67 is a supporting rib for receiving the lid 62.

With the above structure, as in the first embodiment, the wiring work can be efficiently performed, the site construction cost can be reduced, and the line having a sufficient capacity even in a narrow wiring space can be obtained. The excellent effect of being able to accommodate Moreover, particularly in the present embodiment, the tubular wire 3
When 1 is bent so as to be branched in the binding box 60, as shown in FIG. 6, the inner circumference side of the bent portion hits the bending restricting portion 66, so that the radius of curvature of the tubed wire 31 is reliably prevented from becoming excessively small. Therefore, there is an advantage that it is possible to prevent excessive stress from acting on the internal electric wire.

<Other Embodiments> The present invention is not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention. In addition to the above, various modifications can be made without departing from the scope of the invention.
