Description

Structural panel.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a panel structural whose purpose is to provide a honeycomb panel applicable to the manufacture of any sheet product that allow greater rigidity than conventional panels.

It also avoids the bulges that occur frequently in said conventional panels.

For this, the invention incorporates a plate intermediate in the corresponding alveolar structure of the panel that It gives it greater rigidity.

Background of the invention

The panels for false floors of car boot that includes a honeycomb structure central arranged between two plates of thermoplastic resin, being able to interpose between said structure and plates one or more stiffener sheets, and the panel can be coated externally with a textile material, leather or other material. Such configuration known for the panels is the one presented by the Utility Model no. U 200402580. Although the aforementioned known configuration resolved problems of lack of rigidity in the panels of the previous state of the technique has drawbacks related to its rigidity being likely to be improved using less thermoplastic resins and in addition, these known panels sometimes have the drawback that various bulges occur in them.

Thus, to achieve rigidity in honeycomb panels cardboard, thermoplastic resins such as polyurethane or fiberglass. However, due to the humidity generated in the honeycomb structure when placing the corresponding sheets on the same and then add the resins, you can reach generate the aforementioned bulges harming the final result of the product; also requiring a significant amount of resin so that the product presents the suitable rigidity.

Description of the invention

To achieve the objectives and avoid drawbacks mentioned in the previous sections, the invention consists of a structural panel that is characterized because it comprises a honeycomb structure divided into two parts according to a horizontal plane parallel to the main plane of the structure and so that said two parts are joined together by an intermediate layer or plate that separates two portions of honeycomb structure of the same thickness, although said portions They could also have different thicknesses.

In the preferred embodiment of the invention, the referred layer or intermediate plate is a sheet of the same material that the alveolar structure and with a uniform thickness much smaller than the thickness of each part of the honeycomb structure that interconnects. Specifically, in this embodiment to which we have alluded, the referred intermediate plate is a cardboard sheet.

With the structure and configuration that has been described, the panel of the invention has the advantages that at incorporate an intermediate layer in the honeycomb structure achieves greater rigidity of the panel, the amount being smaller resin needed to stiffen the panel, and also with said intermediate layer the bulges that are avoided produced in conventional panels. So, to get different degrees of stiffness with more resin thermoplastic, the final cost of the panel is reduced, allowing the at the same time a superior quality of the product obtained.

Then, to facilitate a better understanding of this descriptive report and being an integral part of the same, a single figure is accompanied, in which with character illustrative and not limiting the object of the invention.

Brief description of the drawings

Figure 1.- Represents a perspective view of a structural panel, object of the invention.

Description of the preferred embodiment

Following is a description of a example of the invention with reference to numbering Adopted in the figures.

Thus, the structural panel of this example of the invention has a honeycomb structure 2 of nest type of bee or with cells of another geometry other than hexagonal, which It is made of cardboard, honeycomb structure 2 that is centrally divided into two equal parts according to a parallel plane to the main faces of the structure and so that the two parts generated by said plane are joined through an intermediate layer or plate 1 which in the present example consists on a cardboard sheet.

Although in the present example the central sheet or  intermediate 1 is made of cardboard, like the honeycomb structure 2, in other examples it can be of other materials and present some different proportions from those shown in the figures.

The structural panel of the invention has a  greater rigidity than conventional panels in which the honeycomb structure is continuous, which makes it necessary to smaller amount of thermoplastic resin for stiffness equal to or greater than that of conventional panels, avoiding also the bulges that occur in said panels conventional.

Claims (3)
