Abstract

The invention relates to the characteristics of a panel made up of two thin slabs made of concrete reinforced by a perforated metal sheet 1 (which replaces conventional reinforcement) sandwiching a thermally insulating element 3. These concrete slabs are connected together by means of reinforced concrete connectors 2. The thermally insulating element having the same dimension as the slabs (excluding thickness) provides, simply by its position inside the panel, the system for interlocking between panels. The thickness of the insulating element and therefore of the connectors enables the inertia and the insulating capabilities of the panel to be varied. The thickness of the thin load-bearing slabs remains unchanged. The consequence of this that the more the panel is thermally insulating, the better it resists the forces which are applied to it. The juxtaposition of the panels according to the invention is particularly intended for the construction of the resisting and insulating components of the building.

Description

La présente invention concerne la possibilité de créer une paroi en emboitant des panneaux constitués de deux plaques minces en béton entre lesquelles est implante un isolant thermique rigide. The present invention relates to the possibility of creating a wall by fitting panels made up of two thin concrete plates between which is implanted a rigid thermal insulator.

Les panneaux ainsi constitués permettent de réaliser les parois porteuses et isolantes de chambres froides, de murs, de planchers, de supports de toiture pour les batiments à usage industriel, commercial, de bureaux ou d'habitation, etc... The panels thus formed make it possible to produce the load-bearing and insulating walls of cold rooms, walls, floors, roof supports for buildings for industrial, commercial, office or residential use, etc.

Traditionnerlement de tels panneaux en béton étaient constitués avec des parois épaisses nécessitées par l'enrobage des armatures à béton traditionnelles. Ils comportaient un pont thermique au droit des renforts ou des liaisons entre panneaux. En général, plus on augmentait les capacités isolantes de tels panneaux plus ieur résistance mécanique devenait faible. Traditionally, such concrete panels were made with thick walls required by the coating of traditional concrete reinforcements. They included a thermal bridge to the right of the reinforcements or the connections between panels. In general, the more the insulating capacities of such panels were increased, the lower their mechanical strength became.

Le dispositif objet de l'invention permet de diminuer l'épaisseur de parois en béton et donc le poids du panneau car une tôle perforée (1), dont le diamètre des trous est supérieur au plus gros élément de gran lométrie du béton mais inférieur à 'entraxe des trous, dans toute la surface du panneau rient renforcer le béton des plaques. The device which is the subject of the invention makes it possible to reduce the thickness of concrete walls and therefore the weight of the panel because a perforated sheet (1), the diameter of the holes of which is greater than the largest element of gran lometry of the concrete but less than 'center of the holes, in all the surface of the panel laugh to reinforce the concrete of the plates.

Cette tôle perforée plane et mince assure par l'intermédiaire des aciers des connecteurs (2) des quaiités mécaniques exceptionnelles jusqutà abaisser l'épaisseur des éléments porteurs du panneau à 4 cm
L'inertie des panneaux est assurée par l'écartement des plaques e béton ; le.moment d'inertie d'une section par rapport à son centre de gravité dépendant du carré du bras de levier des élements.This flat and thin perforated sheet ensures exceptional mechanical quaiities through the steel connectors (2) until the thickness of the load-bearing elements of the panel is reduced to 4 cm.
The inertia of the panels is ensured by the spacing of the concrete plates; the moment of inertia of a section relative to its center of gravity depending on the square of the lever arm of the elements.

Les connecteurs participent à la solidité du panneau notamment ilc interviennent en travaillant remarquablement bien aux efforts de flam. The connectors contribute to the solidity of the panel, in particular they intervene by working remarkably well in the efforts of flame.

bage dans le sens longitudinal. Ce qui fait que plus le panneau est isc lant, plus l'ensemble de ses qualités mécaniques devient important. I est donc possible de reprendre des poussées de terre par exemple as un tel panneau isolant lorsqutil est 'tenu" en tête et en pied.bage in the longitudinal direction. This means that the more insulating the panel, the more important all of its mechanical qualities become. It is therefore possible to take up earth thrusts for example as such an insulating panel when it is 'held' at the head and at the foot.

Le positionnement des panneaux entre eux est assuré par un embo
tement à tenons et mortaises (3) tenons sur deux faces contigues, et mortaises sur les deux autres faces. Les tenons et les mortaises sor assurés par un déplacement, suivant deux axes perpend oculaires: du panneau isolant par rapport aux plaques de béton, le panneau isolant ayant rigoureusement la même longueur et la même largeur que les plaques en béton. Les caractéristiques thermiques du complexe dé- pendent de la nature et de l'épaisseur de l'isolant rigide et donc de la longueur des connecteurs en béton armé. Plus le panneau est isolant plus il est résistant au flambage et aux efforts normaux.The positioning of the panels between them is ensured by an embo
tenons and mortises (3) tenons on two contiguous faces, and mortises on the other two faces. The tenons and mortises are provided by a displacement, along two perpendicular axes: from the insulating panel relative to the concrete slabs, the insulating panel having rigorously the same length and the same width as the concrete slabs. The thermal characteristics of the complex depend on the nature and thickness of the rigid insulation and therefore on the length of the reinforced concrete connectors. The more insulating the panel, the more resistant it is to buckling and normal forces.

L'étanchéité à l'eau et à Irair de la paroi réalisée avec ces panneaux est assurée par une rainure périmétrique (4) en V ou en demi rond ménagée sur le chant de la plaque externe. Cette rainure est bourrée de mastic ou remplie à la pompe une fois les panneaux assemblés. The water and airtightness of the wall produced with these panels is ensured by a perimeter groove (4) in V or in half-round formed on the edge of the external plate. This groove is stuffed with sealant or filled at the pump once the panels are assembled.

Côté interne de la paroi, la même rainure périmétrique existe tout ie tour du chant de la plaque en béton, mais celle-ci est laissée vide si la paroi reste telle quelle ou remplie à l'enduit à joint puis recouverte d'une bande textile ou en papier sur toute la longueur. Cette bande étant ensuite recouverte d'une fine épaisseur dienduit (5). Dans le cas d'une utilisation en plancher ou en support de toiture les deux rainures (4) sont bourrées au mortier. Internal side of the wall, the same perimeter groove exists all around the edge of the concrete plate, but this is left empty if the wall remains as it is or filled with joint plaster and then covered with a textile band or in paper over the entire length. This strip is then covered with a thin coating thickness (5). In the case of use as a floor or as a roof support, the two grooves (4) are stuffed with mortar.

Les joints transversaux aussi bien extérieur qutintérieur sont réalisés de la même manière.  The transverse joints both outside and inside are made in the same way.
