Abstract

The panel has a core (68) of an insulating material sandwiched between two layers of resin-impregnated fibres (64, 65). The core is traversed by cross-pieces (66) perpendicular to the fibre layers and having their heads (69, 70) embedded in the resin, each head having a ring and a button with fibres gripped between them. At least one of the panel's outer surfaces is finished with a layer of an organic coating, plaster or wood.

Description

Field of the invention

The present invention relates to a panel of prefabricated construction with a material core insulating.

Description of the prior art.

panneaux en plâtre extrudé avec alvéoles n offrant pas ou peu de possibilités d ancrage;

panneaux avec structures de bois ou de fer isolés en milieu, peu résistant à 1 eau et ayant les faces, soit en bois, soit en plâtre extrudé, soit encore en enduit organique ou plus rarement en béton ;

panneaux à une face en béton structuré et une autre face en induit collé sur isolant, de mise en uvre plus difficile et dont une face ne permet pas d ancrage;

panneaux en plastiques alvéolés;

etcThere are a multitude of such prefabricated panels, having simple separation functions, such as for example:

panels in extruded plaster with cells offering little or no anchoring possibilities;

panels with wooden or iron structures insulated in the middle, not very resistant to water and having the faces, either of wood, or of extruded plaster, or even in organic coating or more rarely in concrete;

panels with one side in structured concrete and another side in armature bonded to insulation, more difficult to implement and one side of which does not allow anchoring;

cellular plastic panels;

etc.

• rigidité suffisante pour résister aux chocs entre autres aux chocs frontaux et pour permettre de façon aisée un ancrage de support pour cadres ou tout autre objet à suspendre;
• haut pouvoir isolant;
• résistant à 1 humidité.

None of these existing panels now simultaneously offers the following possibilities:

• sufficient rigidity to withstand impact, inter alia, frontal impact and to easily allow anchoring of support for frames or any other object to be suspended;
• high insulating power;
• moisture resistant.

The object of the invention is to remedy these problems.

Summary of the invention:

For this purpose, the building panel according to 1 invention is characterized in that 1 core is sandwiched between two resin impregnated fiber layers.

There are so-called high performance fibers such as for example Kevlar (aramid fiber), Spectra (fiber polyolefine) or Vectran (aromatic polyester fiber). Some of these fibers are thermoplastic polymers affordable and very good tensile strength (± ten times that of 1 steel). By associating these properties with those of other rigid materials (e.g. some polyurethanes or P.V.C.), by a simple process impregnation, sewing (stiffening thread) and completing this treatment (once the first stiffening obtained) by a projection of thermoplastic material under fluid state, good resistance to cuts and buckling for an attractive price. This "stiffening" in composite structure gives a holding mechanical more than satisfactory to the construction panel and is easy to implement. Like fiber layers impregnated materials are not very conductive of noise and heat and that these layers include 1 insulating core without thermal or acoustic conduction bridges, it follows that the panels have a high insulating power. Like 1 soul is covered on its sides with a layer of resin, 1 core is protected against 1 humidity and the panel is hermetic to 1 humidity.

Preferably, sleepers pass through 1 insulation so essentially perpendicular to the panel. These sleepers are provided, at their ends, with heads secured to the sleepers. These heads are embedded in layers of fibers impregnated with resin, thus forming a whole rigid.

Preferably, the said heads form a mesh network of rectangles on the surface of the insulator in order to ensure a balanced distribution of the tensions.
Advantageously, these rectangles will be squares.

The sleepers can also be tapped to ends. These threads can thus serve as points anchoring for frame supports or any other object to hang on the panel.

Fiber layers and heads can be covered a top coat such as an organic coating, plaster, wood or any other suitable top coat, which further increases impact resistance. This layer can be applied only on one side of the panel or on both sides depending on the degree of finish longed for.

The panel according to 1 invention is therefore "armed". It is also insulating and slightly bearing.
The light lift allows a profiled plastic frame.
The frame will include a sealing elastomer which will be put in place by an eccentric profile affixed to a median metal cross member longitudinally. This way of doing things allows the prefabrication of large area panels. There is no need for pre-installed slides: limited perforations and judiciously distributed in the ceilings and floors correspond to cleats which help the fixing undertaken by means of the eccentric thrust exerted on the sealing elastomer forming the edge of the panel.
There is no risk of infiltration of air, water, mini dust. In addition, 1 sound insulation is perfect.
