DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double floor structure for a so-called OA floor used for floors of offices and the like. A limited and improved support leg unit and double floor structure is provided.

[0002]

2. Description of the Related Art In this type of conventional double floor structure,
A base sheet with a plurality of support legs is spread over the entire surface of the base such as concrete, and a floor panel is placed on the support legs, and a finishing material such as a tile carpet is displayed and completed. Was.

FIG. 1 is a perspective view of a double floor showing this conventional method. A polypropylene base sheet 3 having nine supporting legs 2 formed at equal intervals on a concrete base 1 is shown. A structure in which a floor panel 4 made of a synthetic resin is placed on the support legs 2 constituting the square corner, and a tile carpet 5 is extended therefrom. Has become.

[0004]

However, in such a structure, the floor panel 4 cannot be mounted unless the base sheet 3 is laid on the base 1 without gaps. Therefore, the laying work requires not only time but also accuracy. Furthermore,
If the surface of the base 1 has irregularities, the base sheet
It was difficult to lay the Toh 3 and improvement was required in these respects.

The present invention has been made in order to improve the above-mentioned drawbacks, and minimizes the work of specifying the installation position of the support leg, so that the installation of the support leg on the base 1 is simple. Another object of the present invention is to provide a double-floor structure that can be used for a vehicle.

SUMMARY OF THE INVENTION A first aspect of the present invention is directed to a support leg unit constituting a double floor, comprising a plurality of floor units arranged at intervals corresponding to a vertical width and a horizontal width of a floor panel. A supporting leg, a first connecting member connecting between the supporting legs, a second connecting member extending in a longitudinal direction or a lateral direction opposite to the first connecting member from the supporting leg, and a floor panel connected to the second connecting member. And a ring that is arranged at a position corresponding to the vertical width or the horizontal width of the support leg and is fitted to the support leg from above, and a double-floor support leg unit, which is preferably the same as a different support leg. A second connecting member and a ring extending in a direction, wherein the first connecting member is a rib for connecting between the plurality of support legs, and the second connecting member is a rib for connecting between the support leg and the ring. Is a double-floor support leg unit.

A second aspect of the present invention relates to a double-floor structure using a plurality of the above-described units, and another supporting leg adjacent to the supporting leg of the supporting leg unit provided on the base first. The ring of the support leg unit is fitted from above to form a double-floor support leg, a floor panel is placed on the support leg, and a finishing material is laid on the floor panel. It is characterized by.

[0008]

[0009]

The first aspect of the present invention is the structure of the support leg unit as described above. By deciding one place where the support leg is to be installed, the support leg unit is simply placed on the base in order. The supporting legs are surely provided at predetermined intervals.

That is, in the second double-floor structure of the present invention using the support leg unit, a ring is provided between the support leg unit installed first and the support leg unit adjacent thereto. And the supporting legs are fitted to each other and placed on a base, and a floor panel is arranged on the supporting legs to complete a double floor. Preferably, a plurality of rings are provided in one direction, and by fitting the support legs of the adjacent support leg units to the plurality of rings, the position of the ring is more reliable.

[0011]

The double-floor support leg unit in the present invention is preferably made of synthetic resin formed by injection, and among them, the one made of polypropylene has a great merit in cost.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 2 is a front view showing the first support leg unit of the present invention, and FIG. 3 is a sectional view taken along line AA in FIG. FIG. 4 is a cross-sectional view showing the arrangement of adjacent support leg units.

In the drawing, reference numeral 11 denotes a support leg. In the illustrated example, nine support legs 11 are arranged at equal intervals, and this is a grid-like support leg unit connected by ribs 12. . Then, at right angles in two directions to the support legs 11 _1, the support legs 11 _3, 11 _7, respectively rib 1 in one direction from the
3 extends, and a ring 14 is formed at this tip. The ring 14 connected by the rib 13 is a ring 1
The space between the center of 4 and the support legs 11 ₁ , 11 ₃ , 11 ₇ has the same distance as the distance between the support legs 11, 11. These rings 14 are large enough to be fitted to the support legs 11.

FIG. 4 shows a second double-floor structure of the present invention comprising the above-described support leg unit. If the support leg unit A is first placed at a predetermined position, this support leg 11 against _a, by fitting the ring 14 _B of the support adjacent legs unit B, and spacing of the support legs 11 _a and 11 _B and thus to maintain a constant spacing. Therefore, the floor panel 20 can be easily mounted on the adjacent support legs. The core of the floor panel 20
On the nail, a projection 21 is formed toward the head of the support leg, while a recess 15 is provided in the head of the support leg 11 so that they are fitted to fit the floor panel 20 and the finishing material 2.
2 is preferably completed. Further, while between the support legs 11 _A and the support legs 11 and the ring 14, and it is preferably coupled at the rib 13, some irregularities occur in the base plate surface to a rib 13 which is absorbed by this Become.

[0022]

According to the first support leg unit of the present invention, by determining one place where the support leg is to be installed, only the support leg and the ring of the support leg unit are placed on the base while being sequentially fitted. Thus, the supporting legs are surely provided at predetermined intervals. Therefore, not only the construction of the second double floor of the present invention using this support leg unit is simplified, but also the time required for the construction is greatly reduced.
