DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring system for a building having a room capable of accommodating recent OA equipment.

[0002]

2. Description of the Related Art Conventional wiring equipment is divided into high-power equipment for electric power and low-power equipment such as telephone lines after a trunk line.

[0003] Cables according to the use are divided and stored in a trunk shaft (core) penetrating up and down in the building, and cables corresponding to the use are fixed and sorted in the fixed lift floor of the corridor and the ceiling duct on each floor. And wired them, and took them out in the office room where they were needed.

[0004]

In such a conventional wiring facility, in order to cope with an increase in the number of communication lines and an increase in the required power capacity, the ceiling duct has a margin from the beginning, and the conduit pipe buried in the wall is also required. Although it was provided extra, it could not cope with changing the installation location of the OA equipment.

[0005] Therefore, although a free access floor and undercarpet wiring are adopted, the wiring route becomes complicated, it is difficult to completely separate the strong and weak electric cables, and it is necessary to remove floor panels over a wide range of construction. was there.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a spare wiring route that directly connects a core to an indoor location where wiring needs to be added, and to change the position or malfunction (interference) of OA equipment. Etc.) to provide wiring facilities for buildings that are effective for prevention and the like.

[0007]

In order to achieve the above-mentioned object, the wiring equipment for a building according to the present invention uses the wiring laid under the floor of the raised floor from the main shaft for electric wiring as the wiring at the time of building completion, and reserves the wiring. A hole communicating with the groove of the deck plate is provided from the trunk shaft and the required floor under the floor, and the groove is formed as a cellular duct, and a wiring area connecting the trunk shaft and the floor under the room with the cellular duct is provided. It is equipped with it.

[0008]

[Function] Since the cellular duct is a groove in the deck plate,
Under the floor of the room, it is set at a small interval, and the grooves are divided into high current and low current, respectively. As a result, there is no interruption to the weak electric circuit and communication line due to the large current, and additional wiring and wiring changes after building completion are cellular. A duct can be used to directly connect the main shaft (core) and the floor under the room.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A public embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows a cross section of the embodiment. Since this wiring facility 1 is only a spare, it is not normally connected,
In order to simplify the later wiring work, various cables may be passed in advance according to the expansion schedule.

A trunk shaft (also referred to as a core) 3 is a wiring space vertically penetrating the inside of the building, and is branched by a distribution board 5 on each floor and distributed to a required location. In the figure, the distribution board 5 is installed on the floor slab 7 and near the wall 9. The wall 9 forms a space of a fixed width with the opposing wall 9a, and this space is a corridor 11.

A fixed floor 13 is provided in the corridor 11, and a space below the floor 13 is used as a wiring space. Therefore, floor 1
3, a wiring hole leading to the distribution board 5 on the opposite side of the wall 9 and a wiring hole leading to the room 15 are formed.
The cable drawn out of the cable passes through the wiring hole and enters the floor 13.

A cable 14 is passed from under the floor 13 to a room 15 through a wiring hole. A free access floor 17 is adopted in the room 15 so that it can easily correspond to OA equipment, and the cable 14 taken out from under the floor 13 is the floor 1
Wiring is under the floor of 7.

Further, for the purpose of responding to future expansion work,
A wiring hole 21 communicating with the deck plate 19 is provided below the distribution board 5. The wiring holes 21 are long in a direction orthogonal to the grooves 22, 22a, 22b so as to communicate with at least the three grooves 22, 22a, 22b of the deck plate 19, or three wiring holes 21 are provided in accordance with the respective grooves 22 to 22b.

On the other hand, even in the room 15, the deck plate 1
The wiring holes 23, 23a, 23b are bored at arbitrary locations communicating with the grooves 22, 22a, 22b of 9 and the cable from the wiring hole 21 is taken out under the free access floor 17. The details are shown in cross section in FIG. A cell cover 24 is attached to each groove 22, 22a, 22b to form a cellular duct 26.
It is preferable that a floor marker be marked on the panel surface of the free access floor 17 corresponding to the position of each of the wiring holes 23, 23a, and 23b to clearly indicate the cable pull-out position.
In this manner, a cellular duct 26 that leads from the separator 5 to the floor of the room 15 and a wiring facility for the wiring path are prepared.

When it is necessary to add an additional cable after the completion of the building, the cables connected and branched by the distribution board 5 and communication lines of another system are separately passed from the wiring hole 21 into the grooves 22, 22a, for example. It is raised from the floor 23 of the room 15 under the floor and pulled out.

A power cable is passed through the groove 22 so that the groove 2
2a is a cable for information between OA equipment, and a groove 22b is for storing a telephone line. Each cable is separately ionized and wired. There is no need to confuse the wiring under the access floor 17 or dismantle the fried floor 13
Weak electrical systems are separately expanded

[0018]

As described above in detail, according to the wiring equipment for a building according to the present invention, in addition to the wiring equipment required when the building is completed, a wiring area extending from the main shaft to the room through the serral duct is also reserved. Therefore, when additional wiring or wiring is changed after the completion of the building, the area where the floor panel or the raised floor is vacated can be extremely small, and the construction process can be simplified.

Further, since the cellular duct is configured in advance as a spare, a duct communicating with a required position is prepared finely during the construction work of the building, and the crossing of the wiring and the cables for the high voltage and the low voltage are connected to the same duct. This eliminates the need to fit inside, and is also beneficial from the viewpoint of circuit protection of OA equipment equipped with recent advanced electronic circuits.
