[Industrial applications]

 The present invention relates to a double floor structure suitable for laying a power cord, a signal cable and the like on a floor base in a room where an office machine such as a computer is installed.

[0002]

[Prior Art]

 For example, in Japanese Utility Model Publication No. 63-11246, on a top surface of a flat plate portion having at least three sides, a large number of floor boards provided with a flexible covering material covering the top surface are provided. In addition, they are placed on the floor surface, and on the side faces of the flat plate portions of the abutted floor plates, conductive cable pull-out grooves are formed as appropriate along the vertical direction and open to the upper and lower surfaces of the flat plate portion. A floor structure is disclosed.

The leg part of the floor board in this floor structure is composed of an upper leg part which is a vertically long rod-shaped body made of metal and a lower leg part screwed into the upper leg part, and has a long length. The height of the floorboard is adjusted by adjusting the height. Therefore, to arrange the floor plate, it is necessary to rotate the lower leg part to adjust the height, and if it can withstand weight and vibration, the mechanism will be expensive and the number of the mechanism will be reduced. If the distance between the legs is widened to reduce the load, it is necessary to increase the thickness of the floorboard to withstand the load, which makes the floorboard transportation and laying work complicated and difficult.

In order to eliminate the complexity of the height adjustment of the conventional example, for example, Japanese Utility Model Publication No. 2-18174 discloses a synthetic resin having a rectangular or square shape separated from each other and having legs integrally formed at four corners. There is disclosed a floor panel in which the following small panel pieces are connected to each other to form a unit aggregate, and an elastic floor finishing material such as tile carpet is attached to the surface of the aggregate. In this floor panel, it is shown that the tip of the small panel piece is slightly thinned, it is easily deformed, and the absorption of unevenness of the floor base is improved.

[0005]

[Problems to be Solved by the Invention] However, in the above-mentioned improved floor panel, since the unevenness is absorbed by the creep of the legs of the small panel piece, if the heavy object is left standing for a long time, the small panel piece will be It is expected to transform. Moreover, since the small panel pieces are connected to each other by adhering a floor finish made of tile carpet or PVC foam elastic floor material to the surface of the unit assembly, the small panel pieces are the floor finish materials. It must be a material that can be adhered to, which narrows the choice of materials.

An object of the present invention is to provide a double floor structure that eliminates the above-mentioned conventional drawbacks.

[0007]

[Means for Solving the Problems]

 The double-floor structure of this invention has four square small plastic panels that have legs in at least four corners and are integrally provided with male and female connecting mechanisms on each of the two sides forming one corner. , A substantially square floor panel is detachably connected to each other by the connecting mechanism, and the floor panel is separated by a connecting cap made of a flexible material inserted into the grounding side surface of the leg located at the corner. Since it is interconnected with the floor panel of, the problem can be solved.

That is, since this small panel is integrally provided with connecting mechanisms each having a male-female relationship structure on two adjacent sides forming one corner, four pieces having the same shape are combined. By itself, a substantially square floor panel is formed. Therefore, the injection mold for floor panel manufacturing can be downsized to the size of a small panel, and even if the molded product is manufactured from only one single-piece molding mold, the floor can be assembled by assembling them. You can get a panel.

A predetermined laying range is integrally connected to the floor panel by a connection cap inserted into a grounding side surface of a small panel leg located at a corner thereof. Since this connecting cap and other caps inserted in the other legs are molded from a flexible material, deformation of these caps absorbs the unevenness of the floor base, and the small joints Since a gap is formed between the legs of the panels, the small floor panel can be used to deal with the unevenness of the floor base, and the laid floor panels will not rattle.

[Effect of the device]

 Since the double floor structure of this invention is composed of small panels connected together, each of them can be injection-molded with high dimensional accuracy and a short molding time. Even if it is used, the load resistance becomes large and the wall thickness can be reduced.

Also, the small panel has a single shape, and even if it is basically a method of molding from one single-cavity mold, it is possible to support a double floor structure with a large laying area, Even if the number of molds is increased or a large number of molds are taken, maintenance and repair of molds are extremely easy.

Since this double-floor structure can be separated into small panels, it is possible to repair the electrical wiring once it has been laid and to install new ones by removing the small panels at the required locations. The movement of the load can be minimized.

Since transportation and laying of small panels are performed in units of floor panels in which the four panels are combined, handling is easier and work is easier than in the case of units of small panels. In addition, when laying, the size of each small panel can be adjusted to the size of the construction site, which facilitates laying.

In addition, the double floor structure of the present invention can cope with the unevenness of the floor base in small panel units, and in addition, the cap mounted on the leg changes the shape of the material, especially Since the elastic deformation can absorb height fluctuations due to unevenness, rattling of the small panel during walking and stumbling due to being caught at the connecting point do not occur.
