Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention is directed to a system floor that is used when installing under-floor shielded wiring for power cables, signal cables, etc. of various devices that realize office automation. Regarding the floor base unit.

(Prior art) Conventionally, as a system floor used when constructing under-floor shielded wiring for power cables, signal cables, etc. of various equipment to realize office automation, for example, the system floor shown in Japanese Utility Model Application Publication No. 1988-76045 is used. Similarly, on the periphery of the rectangular base (floor base) laid on the foundation floor,
A structure in which a rectangular base (floor base) is laid on a foundation floor while interlocking blocks of a specific shape are integrally provided, and the blocks are connected to each other. Alternatively, as shown in Japanese Unexamined Patent Publication No. 60-40472, a plurality of columns are provided on the lower unit, and the upper unit is placed and fixed on the lower unit via the upper unit using the columns, and the upper unit is laid on the foundation floor surface. There are some structures that are designed to do so.

(Problems to be Solved by the Invention) However, the above-mentioned conventional floor structure has problems in various aspects including workability in laying it, adaptability, and the like. That is, in any configuration of the above-mentioned conventional technology, the bottom plate,
The bottom of a base member called a base plate or the like has a flat plate shape, and therefore, if it is not laid in surface contact with the foundation floor surface, it will wobble and its conformability to the foundation floor surface will be impaired.

At this time, in order to stably lay the base members on the same plane, high flatness accuracy is required for the surface finish of the foundation floor. A problem arises.

In addition, in the above-mentioned conventional example, in which the floor base is laid on the foundation floor surface while the inset blocks are connected to each other, there is a gap between each side (four sides) of the floor base and the adjacent floor base. Therefore, the installation work, including the work of fitting the blocks into each other, requires a lot of labor and time, resulting in poor workability. Furthermore, in the above-mentioned structure where the blocks fit together, if the blocks are hardened to firmly connect the floor bases together, the installation process will take more time and the workability will become worse. A problem arises in that the compatibility with the foundation floor surface becomes poor.If the fitting of the blocks into each other is made looser, the installation work becomes easier, but the floor bases cannot be firmly connected to each other, and the upper floor surface A problem arises in that the stability, flatness, etc. of the film are impaired.

In addition, in a structure in which the upper unit is placed and fixed on the lower unit via a plurality of supports, the lower unit is lined up on the foundation floor, and the upper unit is placed and fixed from above. Although it is relatively easy to install the lower units, since the lower units are not connected to each other and are not integrated, a problem arises in that the stability, flatness, etc. of the upper floor surface is impaired.

The present invention has been made in view of the above circumstances, and allows wiring layers to be easily laminated in any area of the underfloor space formed between the foundation floor surface and the floor panel, thereby allowing for the installation of various types and amounts of underfloor wiring. It is an object of the present invention to provide a floor base unit that allows wiring work to be carried out smoothly and allows a large amount of various types of wiring to be shielded and housed under the floor in a reliable and good wiring protection environment.

Another object of the present invention is to provide a floor base unit that is lightweight and inexpensive, has good workability and adaptability, and allows wiring layers to be easily laminated in any area of the underfloor space with simple work. shall be.

[Structure of the Invention] (Means and Effects for Solving the Problems) The present invention provides a floor base having a plurality of pillars supporting a floor panel, and four pillars among the plurality of pillars provided on the floor base. It is placed in a space surrounded by the pillars, has notches at the four corners that engage with a part of the outer circumferential surface of the pillars, and has a hinge in the middle to create a bifold (mountain fold) structure. The separator is provided with a separator whose notched portions come into pressure contact with the four pillars when the separator is extended, and by extending the separator in a flat shape, two upper and lower layers are formed in the space surrounded by the four pillars. It has a structure that allows wiring layers to be formed.This allows wiring layers to be easily stacked in any space between the floor panel and the foundation floor surface, making it possible to perform wiring work for a large number of different types of underfloor wiring. Not only can this be carried out smoothly, but also these various types of wiring can be shielded and housed under the floor in a highly reliable and good wiring protection environment.

Further, the floor base unit of the system floor according to the present invention includes a floor base in which pillars of the same height are provided at the intersections of frames in which a plurality of vertical cables and a plurality of horizontal cables are arranged in a grid pattern, and this floor. It is arranged in a space surrounded by four of the plurality of columns provided on the base, and has notches at the four corners that engage with a part of the outer peripheral surface of the columns, and a hinge in the middle. Set and fold in half (mountain fold)
The structure is provided with a separator whose notched portions come into pressure contact with the four pillars when the separator is extended flatly, and the separator is extended flatly to fill the space surrounded by the four pillars. It has a structure in which two wiring layers, upper and lower, are formed, which allows wiring layers to be easily stacked in any space between the floor panel and the foundation floor, and also when the wiring layer is extended. Due to the expanding action of the separator, the positions of the pillars around the separator are regulated relative to each other.
Since it is possible to create tension between the pillars,
Particularly when the floor base is constituted by a flexible frame, horizontal and vertical distortions (bending) of the floor base can be corrected and the floor base can be reinforced. Furthermore, in this case, the frame, which has multiple vertical cables and multiple horizontal cables arranged in a lattice pattern, supports the floor panel at multiple points with square-shaped partial contact with the foundation floor surface rather than surface contact. The base can be laid on the foundation floor in a stable state, and it is also lightweight, inexpensive, and easy to install.
