Abstract

PURPOSE:To constitute a wiring equipment of a building so that it can easily cope with extension work thereafter by providing an auxiliary wiring region of connecting a trunk line shaft to the inside of a room in addition to wiring necessary for the building when it is completed. CONSTITUTION:A cellular duct is provided between a trunk line shaft 3 and an in-room corridor 11. A wiring communication hole leading to this cellular duct, is drilled in the trunk line shaft 3 and the corridor 11. An auxiliary wiring region thus obtained is left during execution of a building. In extension wiring in the future, cables for weak and strong currents are not mixed but individually separated so that execution can be facilitated.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to wiring equipment for buildings having rooms that can accommodate modern office automation equipment.

0002

2. Description of the Related Art In conventional wiring equipment, heavy electrical equipment for electric power and weak electrical equipment such as telephone lines are separated from each other after a branch line.

[0003] Cables are divided and housed according to their purpose in the trunk shaft (core) that penetrates the top and bottom of the building, and on each floor, the cables corresponding to the purpose are sorted and organized in the fixed raised floors of the hallways and ceiling ducts. They were then wired and taken out in the office room where they were needed.

0004

[Problem to be solved by the invention] In such conventional wiring equipment, in order to cope with the expansion of communication lines and the increase in power demand capacity, ceiling ducts are made to have extra space from the beginning, and conduit pipes buried in walls are also installed. Although extra equipment was provided, it was not possible to accommodate changes such as changing the installation location of OA equipment.

[0005] Therefore, raised floor or undercarpet wiring is used, but the wiring route becomes complicated, it is difficult to completely separate the strong and weak electric cables, and the installation requires removing floor panels over a wide area. was there.

The present invention has been made in view of the above circumstances, and its purpose is to provide a preliminary wiring route that directly connects the core to an indoor position where additional wiring is required, and to prevent changes in the location of OA equipment and malfunctions (interference). The aim is to provide building wiring equipment that is effective in preventing such problems.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the building wiring equipment of the present invention uses the wiring laid from the main shaft for electrical wiring under the raised floor as the wiring at the time of building completion, and as a spare. A hole is provided that communicates with the groove of the deck plate from the main shaft and the required indoor underfloor, and the groove is configured as a cellular duct, and a wiring area is provided in which the cellular duct communicates between the main shaft and the indoor underfloor. It is equipped with these features.

[0008]

[Operation] The cellular duct is a groove in the deck plate, so
As a result of setting grooves at close intervals under the floor of the room and dividing them into high-power and low-power channels, there is no interference with low-power circuits or communication lines due to large currents, and additional wiring or changes to wiring after the building is completed can be made using cellular cables. Use the duct to main shaft (
Wiring can be directly connected between the core) and the indoor floor.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, public embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a cross section of an embodiment. This wiring equipment 1 is just a backup, so it is not normally wired, but
In order to simplify the wiring work later, various cables may be routed in advance in accordance with the planned expansion.

The main shaft (also referred to as core) 3 is a space for wiring that vertically penetrates the inside of the building, and is branched off at distribution boards 5 on each floor and distributed to required locations. In the figure, a distribution board 5 is installed on a floor slab 7 and next to a wall 9. The wall 9 forms a space of a constant width with the opposing wall 9a, and this space is a hallway 11.

A fixed raised floor 13 is provided in the hallway 11, and the space under the floor 13 is used as a wiring space. Therefore, floor 1
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 drilled under the distribution board 5.
The cable pulled out from the wiring hole passes through the wiring hole and enters under the floor 13.

Further, the cable 14 is passed from under the floor 13 to the room 15 through a wiring hole. The room 15 has a free access floor 17 to easily accommodate OA equipment, and the cable 14 taken out from under the floor 13 is connected to the floor 1.
The wiring is under the floor of No.7.

[0014]Furthermore, for the purpose of responding to future expansion construction,
A wiring hole 21 communicating with the deck plate 19 is provided below the distribution board 5. The wiring holes 21 are either long in the direction perpendicular 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 are provided corresponding to the respective grooves 22-22b.

On the other hand, even if you are indoors 15, deck plate 1
Wiring holes 23, 23a, 23b are bored at arbitrary locations corresponding to 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 floor markers are placed on the panel surface of the free access floor 17 corresponding to the positions of the wiring holes 23, 23a, and 23b to clearly indicate the cable pull-out positions. In this way, the cellular duct 26 leading from the separation panel 5 to the underfloor of the room 15 and its wiring path are preliminarily constructed as a wiring facility.

When it becomes necessary to add additional equipment after the building is completed, cables connected and branched at the distribution board 5, communication lines of other systems, etc. are routed separately from the wiring hole 21 into the grooves 22 and 22a, for example. 23 to the floor of the room 15 and pull it out.

Pass the power cable through the groove 22, and
2a is for information cables between OA equipment, groove 22b is for telephone wires, etc., and they are ionized and wired separately, and then pulled out from the wiring holes 23 to 23b that are closest to the required positions in the room 15. Wiring can be mixed up under the access floor 17, and there is no need to dismantle the raised floor 13.
The light electrical system is wired separately.

Effects of the Invention As explained above in detail, the wiring equipment for a building according to the present invention can be used not only for the wiring equipment required at the time of building completion, but also for the wiring area extending from the main shaft to the room through the cellar duct. Therefore, when adding wiring or changing wiring after the building is completed, the area to be left open for floor panels and raised floors is extremely small, which has the effect of simplifying the construction process.

[0019] Furthermore, since a spare cellular duct is configured in advance, the duct that connects to the required location can be prepared in detail during the construction work of the building, and the wiring can be mixed and crossed, and cables for high and low power can be connected to the same duct. This eliminates the need for internal storage, and is also beneficial from the standpoint of circuit protection for office automation equipment equipped with recent advanced electronic circuits.
