Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a raised floor structure for storing wiring for forming an electric wiring path in a room.

The floor wiring method for forming the electric wiring path in the room is conventionally performed by rolling the wiring on the floor and covering it with a protective cover called a protector, or by embedding a steel wiring path called a floor duct in the floor. The way was done. The former has a safety problem because it easily trips over the protective cover during walking, which is unfavorable in terms of aesthetics, and the latter has the drawback that it has a limited amount of wiring that can be accommodated, but also has less freedom of wiring. It is difficult for any of them to cope with the recent spread of OA equipment and computers. In addition, in order to process these wirings, it is possible to use a unit type double floor called free access used in a room that houses a large computer, but these have the freedom of wiring. It is quite expensive, and it has a height of 20 to 40 cm, which increases the floor height of the building, which causes a problem of further cost increase, and is not a generally applicable method. In addition, reflecting the recent situation, simple double floors for offices have been commercialized, but they also had the drawback that no cheap ones that could be used easily were found.

The present invention eliminates these drawbacks, and in recent years
In response to the rapid spread of office automation and the full-scale introduction of new information and communication services, in order to respond to the rapid increase in the amount of wiring that accompanies them, we will use ready-made plate materials with internal hollow parts. The purpose of the present invention is to provide a low-priced floor structure for storing wiring, which allows wiring to be carried out freely and without exposing electric wires, and will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view showing an essential part of an embodiment of the present invention. In the figure, reference numeral 1 denotes a building skeleton floor surface, 2 denotes a liner set on the floor surface, and a plate material 3 having a through hollow portion 4 therein is laid on the liner. The thickness of the liner 2 is adjusted so that the surface between the plate materials is not misaligned when the plate materials 3 are laid side by side, but it is not always necessary when the floor surface is flat and the surface between the plate materials is not misaligned. 5 is a groove. A continuous groove portion 5 formed by laying out a plurality of plate members 3 at regular intervals such that the sides where the ends of the through holes 4 are visible face each other. Cover 6 so that Reference numeral 7 denotes a cover provided at an end of the plate material 3, 8 denotes a wiring outlet provided at an upper portion of the plate material 3, and 9
Is electrical wiring.

The wiring path according to this structure is formed as follows. The through hollow portion 4 of the plate member 3 is used as a wiring path. When the plate materials 3 are arranged so that the through hollow portions 4 are in contact with each other in the through direction, the through hollow portions 4
Are arranged so that they penetrate continuously. In addition, in order to prevent the lateral displacement of the plate material 3, the building body floor surface 1,
The liner 2 and the plate member 3 may be fixed to each other with an adhesive or the like. The groove portion 5 formed by laying the plate materials 3 at a constant interval is covered with a lid 6 and is used as a main wiring path (header tact) orthogonal to the wiring path of the through hollow portion 4. When the liner 2 is used, the effective inner height of the main wiring path is obtained by subtracting the thickness of the lid 6 from the sum of the thickness of the liner 2 and the thickness of the plate member 3. Therefore, by changing the thickness of the liner 2. This dimension can be adjusted.

The wiring 9 to each device installed on this lift is the plate material 3
It is taken out and connected from the wiring outlet 8 provided on the upper part of the. The wiring outlet 8 can be provided at an appropriate position above the through hollow portion 4 by using a means such as a ruler indicating the installable position. The commercially available plate material 3 of this type is made of an asbestos-based material, a cement-based material, or the like, and the wiring outlet 8 can be easily processed.

FIG. 2 is a perspective view showing the structure of the wiring crossing portion in the main wiring path of the groove portion 5. The figure shows a method structure in the case where wiring is performed across the main wiring path from the wiring path of one hollow portion opened to the main wiring path to the wiring path of the hollow portion which opposes. In FIG. 2 (a), reference numeral 10 is a metal receiving object for lifting the wiring 9 in the main wiring path, and the electric wires 9'crossing in the orthogonal direction are passed under the lower portion of the wiring 9 in the main wiring path. Used when making a line. FIG. 2 (b) shows a case where the orthogonal wiring 9'is traversed above the wiring 9 in the main wiring path contrary to the above, and 11 is a metal receiving object for this. The same parts as those in FIG. 1 are designated by the same reference numerals, and the same applies thereafter.

FIGS. 3 (a) and 3 (b) are a side view and an XX sectional view of the essential part of another embodiment of the present invention. The wiring 9 is omitted in FIG. 3 (b). As shown in the figure, instead of the lid 6 of the main wiring path, the lid 12 is used by partially processing the same material as the plate material 3. The lid 12 is formed by cutting the lower surface of the plate material 3 to a position where the through hollow portion 4 is exposed. By using this as the lid 12, the wiring 9 can be branched from the main wiring path and the lid 12 can be freely opened and closed. be able to. Further, as shown in the figure, if only the four corners 12 'of the lid 12 are left uncut and placed on the liner 2 together with the plate 3, the surfaces can be flush with each other.

FIG. 4 is a side view showing a main part of still another embodiment of the present invention, showing an application of the present invention when applied to an existing building. Building floors are generally 2 to 2 above the concrete skeleton floor.
Mortar with a thickness of 3 cm is applied, and vinyl tiles etc. are pasted on top of this. In the figure, 13 is a mortar. By laying the plate materials 3 directly on the floor and removing the mortar from the groove portion 5 in the main wiring path, the effective inner height of the main wiring can be secured. This way,
According to the structure, the thickness of the raised bed can be further reduced,
Even when installed in an office of an existing building, the reduction in ceiling height can be minimized.

INDUSTRIAL APPLICABILITY As described above, the present invention uses the plate material 3 which is a ready-made relatively inexpensive material, and branches the wiring from the main wiring path, intersects the wiring of the main wiring path, and takes out the wiring to any position in the room. It is possible to provide an economical and convenient electric wiring path because it has a raised floor structure that can be freely performed. Since the main wiring path can be appropriately provided at a required position, it is possible to easily form a wiring storage space corresponding to the wiring amount of the device. Further, since the lid covering the main wiring path can be freely attached and detached, the wiring work can be easily performed. Furthermore, because of the lifting structure as described above, the thickness of the entire lifting bed is much thinner than the conventional double-bed system with free access, for example,
It can be about 7-8 cm.

As described above, the raised floor structure of the present invention can accommodate a considerable amount of electric wiring, has a high degree of freedom in wiring, and facilitates wiring work. Moreover, since this lifting structure is constructed by utilizing the materials for walls or floors that are commercially available at low cost,
It is much more economical than other products with similar performance. In addition, since the overall thickness can be reduced, there is little effect on the floor height of the building, and it has the advantage that it can be easily applied to existing buildings. As described above, the present invention is effective and adaptable to the introduction of small computers, OA equipment, and various terminal equipment into general offices due to the recent sophistication and diversification of information and communication services and the rapid generalization of OA. There is an effect that it can be widely used as a convenient means for storing wiring.
