Abstract
A self-supporting panel, for use in construction, consists of an inner layer or core of a compressed fibre material, sandwiched between two outer layers of mineral or organic fibres. The inner core has a maximum density of 480 kg/m cubed, while the outer layers have a maximum density of 320 kg/m cubed. The panel can be made with dimensions of 1000 mm x 500 mm for easy handling and transportation, and the core can be offset relative to the outer layers to form a projecting tongue along two sides and recesses along the other two so that adjacent panels interlock.
Description
Panneau sandwich autoportant pour cloison
La présente invention concerne La fabrication de panneaux sandwichs et est relative à un panneau autoportant d'une densité moyenne égale ou inférieure à 400 Kg/m3.
ActueLLement, Les produits industrialisés de ce type en matériaux sandwichs ne sont pas suffisamment autoportants et présentent divers autres inconvénients. Ces produits ne sont pas en général aisément transportables, permettent difficilement Le rainurage et L'encastrement et nécessitent souvent une main-d'oeuvre qualifiée et importante en durée.
L'objet de L'invention est donc de réaliser un panneau sandwich autoportant, qui ne présente pas ces divers inconvénients.
Un autre objet de L'invention est de réaliser un panneau sandwich autoportant, qui possède d'excellentes caractéristiques de résistance au feu, aux rongeurs et à la moisissure avec une isolation thermique et acoustique performante.
Un panneau sandwich autoportant réalisé suivant l'inven-tion est caractérisé en ce qu'il est constitué d'un élément central ou âme en fibres agglomérées et de deux éléments externes ou plaques en fibres minérales ou organiques recouvrant l'élément central.
Suivant l'invention l'âme ou élément central présente une densité maximale de 480 Kg/m3 et Les plaques ou éléments externes une densité maximale de 320 Kg/m3.
La combinaison des trois éléments, l'âme et les plaques, permet d'obtenir un panneau sandwich autoportant d'une densité moyenne égale'au inférieure à 400 Kg/m3, densité qui variera suivant le dégré hygrométrique et Les épaisseurs de combinai.son.
A titre d'exemples on peut citer pour l'âme en fibres agglomérées appelée aussi en fibragglo, c'est-à-dire des fibres de bois plus un Liant, un produit du commerce vendu sous le nom de DHENACLITE, et pour les plaques en fibres minérales ou organiques un produit du commerce vendu sous le nom de PAN-TERRE.
Les panneaux suivant l'invention se présentent sous La forme de modules, dont Les trois éléments constitutifs sont calibrés aux mêmes dimensions, les éléments externes ou plaques ayant Leurs bords Légèrement galbés sur les quatre côtés.
Les trois éléments d'un module sont assemblés par exemple à l'aide d'un plâtre colle ayant une excellente adhérence avec les deux types de matériaux, L'élément
<EMI ID=1.1>
Languette sur deux 'côtés adjacents et une rainure libre sur les deux autres côtés adjacents.
Pour former une cloison Les différents panneaux ou modules sont assemblés entre eux par exemple aussi à L'aide d'un plâtre colle, Les languettes d'un module s'imbriquant dans les rainures d'autres moduLes.
Comme enduit de finition on peut utiliser la colle d'assemblage.
La faible densité d'une cloison réalisée avec des panneaux modules suivant L'invention permet La pose sur plancher en bois faiblement portant ou sur tout autre plancher sans nécessiter de renfort particulier. Une telle possibilité est d'une grande utilité en rénovation de bâtiments anciens ou de nouveaux bâtiments à structure légère.
La maniabilité des modules - 1 m de Long par 50 cm de large en moyenne - permet un transport aisé en tout lieu, sans nécessiter un effort important de manutention, et un entreposage restreint.
<EMI ID=2.1>
outillage particulièrement onéreux.
Une cloison réalisée à partir de panneaux modules suivant L'invention peut être forée ou rainurée pour par exemple l'encastrement de canalisations diverses et possède une bonne résistance à L'arrachement pour les vis avec ou sans cheville.
Freestanding sandwich panel for partition
The present invention relates to the manufacture of sandwich panels and relates to a self-supporting panel with an average density equal to or less than 400 kg / m3.
Currently, industrialized products of this type made of sandwich materials are not sufficiently self-supporting and have various other drawbacks. These products are not generally easily transportable, make it difficult to groove and embedding and often require a skilled workforce that is long-lasting.
The object of the invention is therefore to produce a self-supporting sandwich panel, which does not have these various drawbacks.
Another object of the invention is to produce a self-supporting sandwich panel, which has excellent characteristics of resistance to fire, rodents and mold with efficient thermal and acoustic insulation.
A self-supporting sandwich panel produced according to the invention is characterized in that it consists of a central element or core of agglomerated fibers and of two external elements or plates of mineral or organic fibers covering the central element.
According to the invention the core or central element has a maximum density of 480 Kg / m3 and the plates or external elements a maximum density of 320 Kg / m3.
The combination of the three elements, the core and the plates, makes it possible to obtain a self-supporting sandwich panel with an average density equal to less than 400 kg / m3, density which will vary according to the hygrometric degree and the thicknesses of the combination. .
By way of examples, mention may be made for the core of agglomerated fibers also called fibragglo, that is to say wood fibers plus a binder, a commercial product sold under the name of DHENACLITE, and for the plates. in mineral or organic fibers a commercial product sold under the name of PAN-TERRE.
The panels according to the invention are in the form of modules, the three constituent elements of which are calibrated to the same dimensions, the external elements or plates having their edges slightly curved on the four sides.
The three elements of a module are assembled for example using an adhesive plaster having excellent adhesion with the two types of material, The element
<EMI ID = 1.1>
Tongue on two adjacent sides and a free groove on the other two adjacent sides.
To form a partition The different panels or modules are assembled together, for example also using an adhesive plaster, The tabs of a module nesting in the grooves of other modules.
As a finishing plaster, assembly glue can be used.
The low density of a partition made with module panels according to the invention allows installation on a lightly load-bearing wooden floor or on any other floor without requiring any special reinforcement. Such a possibility is very useful in renovating old buildings or new buildings with a light structure.
The maneuverability of the modules - 1 m long by 50 cm wide on average - allows easy transport anywhere, without requiring significant handling effort, and limited storage.
<EMI ID = 2.1>
particularly expensive tools.
A partition made from module panels according to the invention can be drilled or grooved for example the embedding of various pipes and has a good resistance to tearing for screws with or without dowel.
