DESCRIPTION

INSULATING SANDWICH PANEL WITH HARD OUTER LAYER

OBJECT OF THE INVENTION

The present invention refers to a sandwich panel with a hard outer skin made of resins or similar, inner reinforcing mesh, and an insulating foamed core of polyurethane or expanded polystyrene or similar, by molding, whose external appearance imitates stone, batter, scraping and, In addition, it can be painted with different colors.

Currently there is no sandwich with these finishing and insulation characteristics together in one panel, since the different systems that can be found are applied layer by layer on the wall itself. In addition, these systems require more labor and time to apply, and are not always applied to manufacturer's specifications.

The sandwich panel object of the present invention guarantees that all the pieces are made the same, with the same shape and measurements and at the level of insulation. The panels have a rigid exterior skin and a quality insulating interior or core, which can vary in different thicknesses.

As it is manufactured in a mold, it allows different finishes in its environment and especially on the visible side of the piece with imitation of stone, batter, scraping and other similar. It allows to make different finishes and shapes in 3D.

This panel allows and facilitates the rehabilitation for thermal insulation of the walls of buildings, easily and safely, facilitates placement and is quick to install.

Another advantage, no less important, is the weight load that other systems represent for the walls of existing buildings, since it must be taken into account that the buildings were designed to withstand certain loads, and the existing insulating rehabilitations have at least four times more weight than the panel object of the present invention.

In summary, these are the advantages and improvements compared to current similar systems:

- Improves the anchoring of the product to the existing wall.

- Prevents small detachments that are so dangerous, both from the panel and from the old coverings, as they remain under the panel fixed with screws to the base of the wall.

- Guarantees a correct application to achieve adequate insulation, since the panel is already made up of different layers in its manufacture, with a resistant resin skin and an insulating core of polyurethane or expanded polystyrene or similar.

- It facilitates the placement since it is fixed to the wall by means of screws, so this installation operation does not need official pallets, anyone with experience in measuring and leveling can place them.

The industrial application of this invention is within the construction and renovation sector, and more specifically, insulating sandwich panels with a hard outer layer.

BACKGROUND OF THE INVENTION

Although no invention identical to the one described has been found, we present below the documents found that reflect the state of the art related to it.

Thus, document ES2323619 refers to a sandwich panel that is made up of a solar thermal collector integrated into an insulating sandwich panel for the construction of light roofs. A watertight set is defined that allows any combination of panels in a roof. In addition, access to the pipe connections of the solar thermal collector is made from inside the house, under cover, as a window and inspection cover have been provided in the sandwich panel, without the need for the installer to access the surface. exterior of the roof once the covering material has been assembled, be it slate, tile, etc.

ES2277738 proposes a panel in which two external sheets basically made of aluminum participate, in which said aluminum appears in the form of an alloy with manganese, silicon and/or magnesium, and an inner core based on aluminum foam, in which hydride participates. of titanium as an expansion agent and in which aluminum can also be alloyed with silicon or magnesium, the outer sheets presenting a reduced thickness of the order of 0.5 or 0.6 mm, while the core presents a much greater thickness, from 6 to 9 mm, with average densities in the range of 0.25 to 0.5 gr/cm, and the outer sheets also being joined to the foam core by means of a metallurgical union by a thermal process. In this way, a light, resistant, fireproof, fire-resistant, stable up to high temperatures, insulating, durable and fully recyclable panel is achieved.

ES1273234 describes a high-impact sandwich panel for furniture characterized by being made from a finishing sheet material, a reinforcing mesh, a core of high-density insulating material and that, at least on the internal face of the panel, establishes a layer of epoxy adhesive on which the union with the core is established.

ES2682461 claims a sound-absorbing sandwich panel for application to a building element, for soundproofing the building element, which has a first layer and a second layer joined to the first layer, where the first layer is arranged on the face of the second layer remote from the building element, characterized in that in any case, partly flat along the second layer, at least one fixing part is provided, which has a plurality of snap-on hook elements releasably with the second layer, wherein the second layer can be fixed by means of the fixing part to a surface of the building element, and wherein the first layer has a higher weight per unit area and/or a higher density than the second layer.

WO2011148002 proposes a fixing system for a panel with an anti-butronage alarm, whose panels are of the sandwich type, with two external metallic faces and an internal area made of electrical insulating material. It is characterized by having at least two perforations or holes at the ends of the panel so that each perforation consists of two different diameters with the intention of preventing the screws or bolts once located in the perforations to fix the plates on the metal profiles ( the support structure of the panels) can communicate the two external metal faces with each other. The hole with the largest diameter covers one of the metal sheets and the one with the smallest diameter covers the insulating material and the other sheet metal. In this way, the head of the metallic fixing member sits on the core of insulating material without touching one of the metallic sheets, but making contact with the other. This allows an electrical installation to be placed on the metal profiles and which will be the conductive part, to activate an alarm when the panel breaks, breaks or breaks.

ES2229858 describes a metallic panel with an embedded metal plate for a false ceiling in which, within the embedding and adjusted to it, there is a block or blanket of insulating material covered by a hermetically sealed protective sheet around its contour, forming a watertight anti-acoustic and isothermal panel for the room where it is installed.

ES2572374 claims a modular sandwich panel with sealing elements, said modular sandwich panel comprising a bottom sheet, a cover, an insulating core between said bottom sheet and said cover, an internal joint, a longitudinal joint on an outer side of said modular sandwich panel, characterized in that said modular sandwich panel further comprises a male corner joint and a female corner joint, each being inserted into a corner of the outer shell, said female corner joint having a cavity for receiving a part of the male corner joint in an adjacent modular sandwich panel, wherein a membrane is provided in the cavity of said female corner joint, and wherein the male corner joint and the female corner joint are provided with a flap.

Conclusions: As can be seen from the research carried out, none of the documents found solve the problems posed as does the proposed invention.

DESCRIPTION OF THE INVENTION

The insulating sandwich panel with a hard exterior layer that is the object of the present invention is made from a panel manufactured in a mold with a rigid outer skin reinforcing mesh and an interior or insulating core of polyurethane or expanded polystyrene or similar, which can vary in different thicknesses.

It can have different finishes, especially on the visible side, with imitation of stone, batter, scraping and other similar, while allowing 3D finishes.

For its fixing there are two ways of anchoring, one that is incorporated or fixed to the panel itself, and another, which is first fixed to the wall and the panel is fixed to the anchor by means of slots in the panel.

Both are fixed with screws directly to the wall, with a metal, plastic or wooden support previously fixed to the wall.

Unless otherwise indicated, all technical and scientific elements used herein have the meaning that is usually understood by a normal person skilled in the art to which this invention pertains. Similar or equivalent procedures and materials to those described herein may be used in the practice of the present invention.
