Description

Description: TECHNICAL FIELD The present invention relates to a structure for storing and guiding electric wiring, and more particularly to a wiring structure using a pillar for incorporating an intelligent (informatization) function.

<< Conventional technology >> Recently, the construction of intelligent buildings (buildings incorporating information functions) has been on the rise due to the automation of office processing. Similarly, the number of remodeling works for existing buildings is also increasing to make them intelligent.

In response to these demands, double floor structures and under carpet wiring are being used.

<< Problems to be Solved by the Invention >> However, since the undercarpet wiring is limited by the thickness of the carpet, wiring of a large capacity cable is impossible.
In the double-floor structure, various equipments are arranged on the floor, so it is inefficient to work by freely removing the upper floor and wiring.

In particular, in a LAN (premise information and communication network) involving optical communication, in the case of an optical cable, the radius of curvature must be increased, and the underfloor structure can be used not only in the double floor structure where the free arrangement range of the wiring facility is narrow. Carpet wiring was even harder to handle. In the case of undercarpet wiring, the diameter of the coaxial cable is also relatively large compared to the thickness of the carpet, and the difference in carpet elasticity between the portion with the cable and the portion without the cable, combined with the aging, markedly damaged only the surface of the wiring path. In some cases, the appearance was spoiled, and in some cases the interior design was unavoidably compromised by exposing the wiring.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a wiring structure using pillars that can sufficiently cope with a change in wiring path and can easily perform high-power and low-power wiring.

<< Means for Solving the Problems >> In order to achieve the above object, the wiring structure using the pillar of the present invention has a sufficient space for passing each cable such as a power line, a power line, and an information communication line around the pillar. It is composed of a pillar shape that covers the circumference of the pillar from the ceiling to the floor surface, a relay terminal for the cable provided in the pillar shape, and a skirting board that is openably and closably provided at the lower end of the pillar shape.

<Operation> Since the inside of the pillar extending from the ceiling to the floor can be communicated with the space above the ceiling, the cable paths for each power line, communication line, etc. can be freely selected and changed, and the baseboard at the lower end of the pillar can be changed appropriately. Open and close as necessary, and pass the necessary cables to the required equipment near the pillar.

<< Example >> FIG. 1 shows a schematic cross section. Each floor slab 1-1 on the upper and lower floors in the figure
Is composed of a deck plate 3 supported by each beam 2-2 that supports the upper and lower floors, and is separated from this floor slab 1 by a ceiling plate 4
Is provided, and a space separated from the back surface of the floor slab 1 to the ceiling plate 4 is a ceiling back space 5. Each beam 2-2 on the upper and lower floors is supported by a pillar 6.

The pillar shape 7 that surrounds the pillar 6 with its upper end in contact with the ceiling plate 4 and its lower end in contact with the floor slab 1 is a plate-shaped ceramic material, wood, thin steel plate, etc., from 100 m / m to 150 m / m from the surface of the pillar 6. A wiring space 8 is formed around the pillar 6 with a space therebetween.

Furthermore, the central portion of the pillar 7 in the horizontal direction is divided vertically by a partition 9, and the wiring space 8 is separated into left and right, and a high-power cable and a low-power cable are separately wired, and the partition 9 is divided into left and right. You may make it arrange | position a strong electric wire and a weak electric wire.

Further, at the lower end of the pillar 7, a skirting board 10 which is slidable in the vertical direction and which can be freely opened and closed is provided, and the cable 11 that has passed through the space 5 behind the ceiling and passed through the wiring space 8 in the pillar 7 is , Baseboard 1
Open 0, take it out to the floor, and connect to the target device from here.

Carpet 12 should be used in case the cable 11 in the pillar 7 is changed or the undercarpet wiring is used later.
In order to change from a multi-core cable to a flat cable on the surface of the pillar 6 corresponding to a slightly upper position, or a cable conversion terminal 13 for connecting the connection terminal is attached, the lower portion of the panels forming the pillar 7 is also detachable. The inspection panel 14 may have a flexible inspection port structure.

FIG. 2 shows the case in which the skirting board 10 at the lower end of the panel of the pillar shape 7 is not completely opened and closed, but is partially opened from the front direction of the opening and closing skirting board 10 and corresponds to the partition 9. Necessary wiring is provided on each of the right and left sides, and a dedicated inspection panel 14 is separately provided below the wiring.

Details of the opening / closing skirting board 10 will be described with reference to FIGS. In FIG. 3, the skirting board 10 slides up and down and is elastically pressed against the panel surface of the column 7 by the corrugated leaf spring 15 to stop and hold the up and down movement.

FIG. 5 shows a cross section of the opening / closing skirting board 10. As shown in the drawing, the lower end of the pillar-shaped panel 7 is cut above the floor slab 1 by about 100 m / m. A holding frame 16 in the shape of an inverted bag having an open bottom is formed on the back surface thereof. Inside the holding frame 16, a holding plate 17 is elastically urged outward by a spring 15 to form a back surface of the pillar-shaped panel 7. The skirting board 10 is held in pressure contact with the holding plate 17. Even if the skirting board 10 is moved upward by the elastic urging force of the spring 15, the skirting board 10 retains its moving position.

An outlet 1 installed in the front position when the skirting board 10 is opened by fixing the midway part of the cable 11 'passing through the space 5 behind the ceiling and the space 8 for wiring surrounded by the pillars 7 with the saddle 18 open.
A cable 11 'is connected to the cable 9. The skirting board 10 is opened upward to supply electric power from the outlet 19. Even if the skirting board 10 is opened from the conversion terminal 13 and the under carpet wiring is used, the panel surface of the low floor type free access floor is set slightly above the height of the skirting board 10 and the wiring cable is opened from the opening portion of the skirting board 10 to the free access floor. You may arrange in the back space of.

<Effect> As described in detail above, in the wiring structure using the pillar of the present invention, the pillar shape surrounding the pillar is slightly separated from the surface of the pillar to obtain a wiring space extending from the ceiling back to the floor surface. As compared with the case where the wiring space is under the floor, there are fewer obstacles in the wiring space, and the communication line and power cable can be freely guided to the position near the required equipment without moving the installation on the floor. You can

In particular, this wiring structure is installed in parallel with a wiring system such as a central duct, and a column-shaped space that communicates with the space above the ceiling for cables that have a large radius of curvature when bending a large amount of wiring, optical fibers, coaxial cables, etc. The correspondence is very effective as it uses.

In addition, a conversion terminal for cable relay is provided in the pillar shape, and even if an undercarpet is adopted, the existing wiring can be used immediately up to its immediate vicinity, so that expensive undercarpet wiring is minimized. Also, since a large-capacity electric power is provided with a baseboard that can be opened and closed at the bottom of the pillar, you can open the baseboard from the pillar near the connected device and take out the power line. Therefore, the exposed wiring or the like does not impair the aesthetics and design.
