Virtually divided into two areas. In the four areas A to D, six work desks, each indicated by a numeral 11 to 16 with the area symbol as a subscript, are grouped and arranged. An information device terminal (not shown) such as a telephone or a computer is disposed on each of the work desks 11 to 16.

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

The wire harness 30 will be described in detail. Each of the wire harnesses 30 is provided with a tubed wire 31 corresponding to a tube-containing line group, and four tubed wires 31 are provided corresponding to the four regions A to D. As shown in FIG. 3, each tubed wire 31 is configured by housing six 8-core multi-twisted pair electric wires 33 in a tube 32. In this embodiment, the multi-twisted pair electric wire 33 is a specification satisfying the category 5 standard. Although not shown, an identification code (for example, A to D) indicating a region corresponding to each tube 32 of the tubed wire 31 is shown.
Or a number from 1 to 4), so that the corresponding area of each tubed wire 31 can be identified at a glance.

The wire harness 30 has the structure shown in FIG.
As shown in (3), binding boxes 40 are provided at three locations on the way from the base end to the tip, and four tubed wires 31 are bound in a horizontal line. The binding box 40 has a flat rectangular shape, and is formed into an upper and lower two-part shape as shown in an enlarged view in FIG. 4, and a line introduction port 41 and a line connection port are provided on each surface facing each other with a space in the longitudinal direction. An outlet 42 is formed, and a branch outlet 43 is formed on the side different from these. Here, FIG. 4 shows one of the three binding boxes 40 located at the intermediate portion, in which three line inlets 41 and two line outlets 42 are formed. In the binding box 40, three tubed wires 31
Is introduced inside, and two lines pass through here, and the line outlet 4
1 and the remaining one is bent substantially perpendicularly to the extension direction of the wire harness 30 and is led out from the branch outlet 43. The above branch outlet 4
Reference numeral 3 denotes an opening extending long along the extension direction of the wire harness 30, so that the binding box 40 can move along the extension direction of the wire harness 30.

A branching device 50 is provided at the end of each of the tubed wires 31. For example, six modular outlets 51 are incorporated therein, and a modular plug (not shown) from an information equipment terminal is inserted into the modular outlet 51. It is to be connected. A cable bundling member 44 having a U-shaped section for accommodating a cable accommodation groove is provided at a required location between the binding boxes 40 in the wire harness 30.

Depending on the position and the position of the terminal board 20, the necessary length of 4
Various types of tubed wires 31 are prepared. Four of the tubed wires 31 are arranged in parallel, and are bundled as one wire harness 30 by passing through the binding box 40. The above operations can be performed at a harness factory.

Next, the wire harness 30 manufactured as described above is carried into a construction site from a harness factory, where it is laid at a predetermined position in a wiring space under the floor. This wiring space is, for example, as shown in FIG.
The floor plate 19 is laid on the support columns 18 erected on the floor, so that the floor plate 19 and the floor slab 17 are formed. Then, the branching device 50 is fixed to a wiring space under the floor or a predetermined position on the floor, and the core wire of each of the tubed wires 31 is connected to the terminal board 20. Since the work of laying the wire harness 30 is completed only by this, a modular plug from an information device terminal such as a telephone or a computer is inserted and connected to each modular outlet 51 of the branching device 50 thereafter, and all the work is completed.

According to the above-described embodiment, 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
