BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double floor structure in which a floor panel is supported by supporting legs at a predetermined interval from a floor base such as a concrete slab.

[0002]

2. Description of the Related Art Recently, office rooms equipped with OA equipment have increased, and it has become a hindrance to keep wiring of OA equipment on the floor. Supporting the floor panel with supporting legs at an interval has been performed. Among the support leg support types, low-floor, non-adjustment-free type low-cost types are increasing recently. The floor panel used there was simply a flat plate, and no consideration was given to weight reduction.

[0003]

In the prior art in which the floor plate and the column are fitted together, a rattling sound is generated when the floor plate is shifted laterally unless the floor plate is fitted without a gap. Further, in order to fit the columns without gaps, it is necessary to make the interval between the columns projecting from the base plate accurate, and to form or mount the concave portion forming portion of the floor plate and the mounting position of the receiving bracket at the correct position. However, there is a problem in that on-site construction takes time, costs are reduced, and quick construction is performed. Therefore, it has been desired to reduce the weight of the floor panel.

In view of the above, the present invention is of a type that does not require a solid adjustment and is designed to reduce the weight of the floor panel so that a slight displacement that is inevitably generated when laying a plurality of floor panels can be easily adjusted at the construction site. It is intended to provide a simple type double floor structure.

[0005]

To achieve the above object, the present invention provides a double floor structure in which a floor panel is detachably provided on a floor substrate such as a concrete slab via supporting legs. The panel is formed with a plurality of recesses in its thickness direction, and projections or recesses are formed on the corners of the lower surface, and the projections or recesses or projections fitted to the support leg upper surfaces are formed. It was formed.

The floor panel of the present invention has a large number of recesses formed over the entire surface of the floor panel in the thickness direction. Since the recess does not penetrate the panel, it is a lightweight yet strong floor panel. In addition, a protrusion is formed at a corner portion of the lower surface of the floor panel so that the protrusion fits into a recess formed in the upper surface of the support leg. Therefore, even if there is a gap when laying a plurality of floor panels, the floor panels are lightweight and can be easily attached and detached by putting fingers or the like in the recesses.
The deviation can be easily adjusted at the construction site.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. In the embodiment shown in FIG.
Alternate recesses 31, 3 from the top and bottom of the floor panel 3
No. 2 is formed, and the cross section has a continuous corrugated shape. FIG. 2 is a bottom view of FIG. 1, in which a large number of square recesses 32 are regularly formed, and a middle portion of each recess 32 is formed with a recess 31 from the upper surface. Projections 3A are formed at each of the four corners.

As shown in FIG. 3, the floor panel 3 is removably mounted on a floor base 1 such as a concrete slab via a support leg 2. In this embodiment, the support leg 2 is mounted. A hollow tube is used to reduce the weight, and a soft material 4 is disposed between the upper surface of the support leg 2 and the floor panel 3. This soft material 4 is fixed to the upper surface of the support leg 2. The support leg 2 and the floor panel 3 are detachably fitted. In this embodiment, a concave portion 2A is formed on the upper surface of the support leg 2, a soft material 4 is fixed along the concave portion 2A, and a projection 3A formed on the lower surface of the floor panel 3 is formed in the concave portion 2A. Although fitted, the recess 2A may be formed on the lower surface of the floor panel 3 and the projection 3A may be formed on the upper surface of the support leg 2. Such concave-convex fitting does not need to be fitted without a gap, and the play of the soft material 4 does not cause rattling noise even if play occurs. The dimensional error within the allowable range of the floor panel 3 may slightly deviate from the position where the floor panel 3 is originally laid when a large number of floor panels 3 are laid. Can be absorbed,
It does not lead to unfitting. Further, a soft sheet 5 is provided between the lower surface of the support leg 2 and the floor substrate 1. Although the soft sheet 5 and the lower surface of the support leg 2 are fixed,
It may be simply placed. Support leg 2 shown in FIG.
The height of the support leg is about 30 mm, and the support leg 2 and the support leg 2
Is about 165 mm, and the soft sheet 5 is formed of polyethylene foam. Examples of the soft material 4 attached to the upper surface of the support leg 2 by means of adhesion or the like include milastomer (thermoplastic rubber-like elastic body), EVA (ethylene-vinyl acetate copolymer), EEA (ethylene-ethyl acrylate). A soft resin such as a copolymer) was used. The support leg 2 and the floor panel 3 were formed of polypropylene. A finishing material such as carpet may be laid on the upper surface of the removable floor panel 3. Further, in this embodiment, a portion corresponding to the hollow portion of the support leg 2 of the soft sheet 5 is cut out to form a hole 5A, thereby reducing the material cost of the soft sheet 5. You may use the soft sheet 5 in which this hole 5A is not formed.

FIG. 4 is a sectional view of another floor panel 3 according to the present invention, in which a number of recesses 31 are formed only from the upper surface.

FIG. 5 is a top view of another floor panel 3 of the present invention, in which a large number of square recesses 31 are regularly formed, and projections 3A are formed at four corners on the lower surface. It is formed.

FIG. 6 shows a support leg 2 and a soft sheet 5.
And a plurality of support legs 2 are fixed on the soft sheet 5 at a predetermined interval. As an example of a method for fixing the soft sheet 5 and the support leg 2, as shown in FIG. 7, while pulling out the polyethylene foam material from the roller, a positioning jig 7 (aluminum plate) is placed on the drawn polyethylene foam material. The support leg 2 was set in each hole of the positioning jig 7, and the lower surface of the support leg 2 and the polyethylene foam forming the flexible sheet 5 were thermally fused by heating. It is of course possible to use an adhesive in addition to the heat fusion.

The soft material 4 is formed by vacuum forming a 1 mm thick mirastomer, cutting it after vacuum forming, and bonding it to the upper surface of the support leg 2. A soft EVA or the like is used instead of the mirastomer. It can also be manufactured by injection molding.
