Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cable gutter for floor wiring suitable for use when forming a cable line on a floor surface of an office building or the like.

[Conventional technology]

In order to cope with the multi-functionalization of office buildings and the like, many cable lines have come to be formed on the floor surface of office buildings and the like.

In the conventional construction of the floor of an office building, the conventional cable line is constructed by piping a pre-established cable duct, then placing concrete, and burying the cable duct in the floor concrete.

However, with this method, there is a problem that inconvenience occurs when wiring is changed, and it is difficult to add cables, and it is not possible to cope with the multifunctionalization of an office building.

Therefore, a wiring method called a free access floor has recently been conceived, and a standing floor is formed with a certain wiring space on the already formed floor surface, and the wiring space under the rising floor is used. It is designed to accommodate additional cables and rewiring.

[Problems to be solved by the device]

As mentioned above, conventionally, a standing floor is formed with a certain wiring space on the already formed floor surface, and the wiring space under the rising floor is used to add cables or change wiring. I was trying to accommodate.

However, with this method, there is a problem that the floor height is lowered by the amount of the rising floor, which worsens the work environment, and there is a risk that, for example, cables for low-power and high-power will coexist and contact each other, There was a problem that it caused problems such as noise.

Therefore, the present invention solves the above-mentioned disadvantages of the conventional floor wiring structure, and a partition gutter is detachably and variably attached in a long cable gutter having an opening on the top surface to provide a floor concrete top surface. A cable gutter for floor wiring that solves problems such as noise by making it possible to integrally form a concave cable line and to separately wire cables for low-power and high-power, respectively. It is intended to be provided.

[Means for Solving the Problems]

The configuration of the present invention for achieving the above object will be described in detail below.
A cable gutter body with an upper opening formed by connecting side plates to the left and right sides of a long bottom plate, and a bottom plate part having a width direction shorter than the width direction length of the bottom plate of this cable gutter body. It consists of a partition gutter with an upper opening formed by connecting side plates on both the left and right sides.Along the width direction of the partition gutter, a long groove is drilled along the width direction, and a screw is inserted over the long groove. By removing the partition gutter to the bottom plate of the cable gutter body so that it can be moved in the left-right direction and can be detachably fixed.By removing the screw to remove the partition gutter, or by loosening the screw to change the position of the partition gutter. The cable gutter for floor wiring is characterized in that the number of cable lines in the main body of the cable gutter is variably configured so as to correspond to one way to three ways.

[Embodiment] Hereinafter, a specific configuration of the present invention will be described in detail based on an illustrated embodiment.

FIG. 1 is a plan view showing an embodiment of the floor wiring cable gutter of the present invention, FIG. 2 is a sectional view taken along line II-II of FIG.
FIG. 3 (a) is an explanatory diagram when the cable line is a two-way, FIG. 3 (b) is an explanatory diagram when the cable line is a one-way, and FIG. 4 is the cable shown in FIG. It is sectional drawing of the state which poured the floor concrete so that it might become the same surface as the upper surface opening part of a gutter.

In the figure, reference numeral 1 denotes a cable gutter body having an upper surface opening formed by connecting side surface plates 3 and 3 on both left and right sides of a long bottom plate 2, and 4 denotes a width direction length of the bottom plate 2 of the cable gutter body 1. On the left and right sides of the bottom plate 5 having a shorter width in the width direction, side plates 6 and 6 are provided.
The partition gutter of the upper surface opening formed by connecting is shown.

In the present invention, the cable gutter body 1 and the partition gutter 4 are used to form a concave cable line on the floor surface of an office building, etc., along the width direction of the bottom plate portion 5 of the partition gutter 4. As shown in FIGS. 1 and 2, a long groove 7 is bored and a screw 8 is inserted from above the long groove 7 to move the partition gutter 4 to the bottom plate 2 of the cable gutter body 1 in the left-right direction. , And the partition gutter 4 is removed from the cable gutter body 1 by removing the screw 8 or the fixing position of the partition gutter 4 in the cable gutter body 1 is changed by loosening the screw 8. As a result, the number of cable lines in the cable gutter body 1 can be changed from one-way to three-way.

The cable gutter main body 1 is arranged on a floor foundation surface 9 made of beams, floor slabs, etc. before pouring the floor concrete via long bolts 10 capable of height adjustment. That is, reference numeral 11 in the drawing denotes an L-shaped plate fixed to the side plates 3 and 3 of the cable gutter main body 1, and the upper portion of the long bolt 10 is screwed into a screw hole formed in the L-shaped plate 11. Floor base surface 9
The arrangement height of the cable gutter main body 1 can be adjusted.

Since the partition gutter 4 is detachably and variably attached to the inside of the cable gutter body 1 as described above, the partition gutter 4 can be attached to the central portion of the cable gutter body 1 as shown in FIG. If it is located at, the side plates 3 and 3 of the cable gutter body 1 and the side plate portions 6 and 6 of the partition gutter 4 form three cable lines 12, 12, 12.

Further, as shown in FIG. 3 (a), the partition gutter 4 is slid along the long groove 7 so that one side plate portion 6 of the partition gutter 4 and one side plate 3 of the cable gutter body 1 are brought into contact with each other. If 2
Two cable lines 12, 12 are formed,
Further, if the screw 8 is removed, the partition gutter 4 can be removed from the cable gutter body 1, and in that case, as shown in FIG. 3 (b), only one cable line 12 is formed.

Therefore, according to the present invention, the number of cable lines can be freely selected according to the type and number of cables used.

In addition, the cable gutter for floor wiring of the present invention comprises a long cable gutter body 1 and a long bolt 1 before pouring the floor concrete.
It is arranged in advance on the floor foundation surface 9 through 0, and then the floor concrete 13 is placed to make the floor concrete 13
The curing surface 14 and the opening on the upper surface of the cable gutter body 1 are almost flush with each other (Fig. 4).
The cable gutter main body 1 acts as a kind of discard formwork, and the cable gutter main body 1 is arranged to form the cable lines 12 on the concrete floor. The number of the cable lines can be changed from one way to three way. It is as described above that it can be changed between the above. Further, although not shown, a lid is attached to the upper opening of the cable gutter body 1, and the same floor material as a floor material such as a tile carpet covering the floor concrete surface is attached to the upper surface of the lid. .

Therefore, when changing the cable line 12, the tile carpet and the lid (not shown) are removed, and the partition gutter 4 is moved by operating the screw 8 in the cable gutter body 1 that has become an opening, whereby the work is easily performed. Is something that can be done.

[Effect of device]

Since the floor girder cable gutter of the present invention has the above-described structure, the number of cable lines can be easily changed and, for example, a cable for low power and a cable for high power can be independently wired. Therefore, it is possible to solve the problems such as noise which have been a problem in the past.

Also, by using the cable gutter of the present invention, it is possible to form a concave cable track on the floor surface of an office building or the like, instead of the conventional free access floor system, which is a problem associated with the free access floor, that is, the floor height. Will be lower. It is possible to solve the problem that it takes a lot of time and labor for work such as wiring change and expansion.
