However, with this method, there is a problem that the floor height is lowered by the riser floor, which worsens the working environment.In addition, when replacing wiring or adding cables, flooring materials such as carpet tiles and floor panels are required. There was a problem in that it had to be removed on a large scale and the work could not be done easily.

Therefore, the present invention solves the above-mentioned problems of the conventional floor wiring structure, and uses a long cable gutter with an opening at the top to integrally form a concave cable track on the concrete floor surface. To provide a floor wiring structure that allows work such as wiring replacement and expansion to be performed easily without affecting the floor height of the building.

[Means to solve the problem]

The structure of the present invention for achieving the above object will be described in detail.
The invention according to the first claim provides that, before placing floor concrete,
A long cable gutter with an opening at the top is placed on the top of the floor foundation surface, and then floor concrete is poured so that the hardened surface of the floor concrete and the top opening of the cable gutter are on the same plane. A floor wiring structure is characterized in that a concave cable line is integrally formed on a concrete floor surface, and the invention according to claim 2 provides a cable line arranged on the upper surface of a floor foundation surface. The floor wiring structure according to claim 1, wherein the gutter is vertically adjustable using a height adjustment bolt.

Further, the invention according to claim 3 is the floor wiring structure according to claim 1 or 2, wherein a lid body is removably attached to the upper opening of the cable gutter, and The claimed invention provides a floor wiring structure according to any one of claims 1 to 3, wherein a long partition gutter is attached to the bottom of the cable gutter so as to be adjustable in the width direction of the cable gutter. be.

It goes without saying that a flooring material such as tile carpet is attached to the upper surface of the lid attached to the upper opening of the cable gutter. When changing the wiring, etc., the cover can be removed and the cable direction within the cable track can be changed.

〔Example〕

Hereinafter, the specific configuration of the floor wiring structure of the present invention will be explained in detail based on the illustrated embodiment.

Figure 1 is a plan view showing an example of a cable gutter installed on the upper surface of the floor foundation surface, Figure 2 is a cross-sectional view taken along line ■1■ in Figure 1, and Figure 3 is the same as Figure 2. Fig. 4 is a cross-sectional view showing a state in which floor concrete is poured so as to be flush with the top opening of the cable gutter, and Fig. 4 is a plan view showing an embodiment in which a partition gutter is attached to the bottom of the cable gutter. be.

In the figure, 1 shows a cable gutter with an opening at the top with side plates 3 erected on both sides of a long bottom part 2, and 4 shows a floor foundation surface made of beams, slabs, etc. before floor concrete is poured. shows.

In the floor wiring structure of the present invention, the cable gutter l is arranged on the upper surface of the floor foundation surface 4 so that its upper surface opening faces upward, and then the floor concrete 5 is poured, and the hardened surface 6 of the floor concrete 5 is placed. A concave cable line 7 is formed on the concrete floor surface so that it is flush with the top opening of the cable gutter l.
are integrally formed.

Since the pouring height of the floor concrete 5 varies depending on the construction site, the installation height of the cable gutter 1 must be freely adjustable. Therefore, in the present invention, the side plates 3, 3 of the cable gutter 1 Fix the L-shaped plate 8.8 in place, and screw the adjustment bolts 9, 9 into the horizontal part of the L-shaped plate 8.8 to adjust the installation height of the cable gutter 1 from the floor foundation surface 4. (Figure 2).

In the wiring structure of the present invention, before placing the floor concrete, a long cable gutter l with an opening at the top is placed on the floor foundation surface 4 in advance, and then the floor concrete 5 is cast so that the hardened surface 6 of the floor concrete 5 and the upper opening of the cable gutter 1 are almost on the same plane.
The cable trough 1 functions as a kind of abandoned formwork, and by arranging the cable trough 1, a concave cable track 7 with a required width is formed on the concrete floor surface.

Note that depending on the construction site, the cable gutter 1 must be stretched vertically and horizontally, so in the present invention, as shown in FIG. This allows them to be orthogonal. Further, floor equipment 11 such as an outlet box is appropriately attached to the side plate 3 of the cable gutter 1.

In addition, 12 in the figure indicates a partition gutter attached to the bottom of the cable gutter l, and a cut arrow part 13 is formed along the width direction at the bottom of the partition gutter l2, as shown in Fig. 4. ,
A screw 14 is inserted into this notch l3 so that it can be fixed to the bottom of the cable gutter l on the lower surface. Therefore,
The partition gutter l2 is movable in the left-right direction within the range of the notch l3, and can be configured as a two-way type or a three-way type depending on the number of cables. It goes without saying that by removing the screw l4 and removing the partition gutter 12 from the cable gutter 1, it can be used as a one-way system.

In addition, 15 in the figure indicates a lid that is attached to the upper opening of the cable gutter 1, and l6 is a supporting metal fitting attached to the inner circumferential surface of the side plate 3.3 of the cable gutter 1 to support the lid l5. shows. Although not shown in the drawings, it goes without saying that the same flooring material as the tile carpet covering the concrete floor is attached to the upper surface of the lid 12.

〔Effect of the invention〕

The floor wiring structure of the present invention has the above-mentioned configuration, and since the cable track is pre-formed on the floor of an ordinary office building, etc., it does not affect the floor height of the building. be.

In addition, when changing wiring or increasing the number of cables, the cable tracks can be exposed on the floor by partially removing flooring such as tile carpet and removing the cover, so even ordinary users can use it for example with table taps etc. The work can be done easily using the . Therefore, according to the present invention, the problems associated with conventional raised floors can be solved with a simple structure.
