  ELEMENT D'ISOLATION ACOUSTIQUE ET THERMIQUE A DOUBLE FOND,
NOTAMMENT ELEMENT DE PLANCHEIAGE OU DE CLOISONNEMENT 
La présente invention se rapporte à un élément d'isolation acoustique et thermique à double fond, pouvant être employé en tant qu'élément de planchéiage ou de cloisonnement. 



   D'après le document   FR-A-2 195 744, l'on connaît une dalle   à double fond de ce type, dans laquelle un matériau central est recouvert d'une plaque sur ses faces supérieure et inférieure, un revêtement de sol étant collé sur la plaque supérieure. 



   Le collage distinct d'un revêtement, d'une couche de protection ou d'une couche de décoration représente, au stade de la fabrication de telles dalles à double fond, une intervention supplémentaire qui n'est pas économique abstraction faite de la présence, dans la dalle, de la couche additionnelle d'adhésif. 



   Conformément à l'invention, cet inconvénient est éliminé en fournissant un élément à double fond d'un type perfectionné. 



   L'invention va à présent être décrite plus en détail à titre d'exemple nullement limitatif, en regard du dessin annexé sur lequel la figure unique est une perspective fragmentaire, avec arrachement, d'un élément à double fond conforme à 
 EMI1.1 
 l'invention. 



   Comme le montre la figure unique, l'invention concerne un élément à double fond comprenant un matériau central 1 qui est recouvert, sur ses faces supérieure et inférieure, par une plaque respective 2 ou 3 en une matière thermoplastique renforcée par des fibres, la plaque supérieure 3 en une matière thermoplastique renforcée par des fibres étant munie d'un revêtement 4 qui est relié, à ladite plaque 3, sans le concours. d'aucun adhésif. Les côtés du matériau central 1, non recouverts d'une plaque, sont recouverts d'un chemisage métallique 5. Ce chemisage métallique 5 forme, dans une certaine mesure, un cadre qui est intimement ancré avec les plaques renforcées par des 

 <Desc/Clms Page number 2> 

 fibres.

   Cela est obtenu par le fait que le chemisage 5 est plus large que l'épaisseur du matériau central 1, et est coudé à angle droit       la hauteur des plaques 2,3 renforcées par des fibres, les surfaces métalliques coudées reposant alors sur les zones marginales des faces supérieure et inférieure dudit matériau 1, et étant coiffées par lesdites plaques 2,3 auxquelles elles sont reliées. Cette structure composite est améliorée du fait que le chemisage métallique 5 est perforé. Une autre amélioration de la structure composite résulte du fait que les perforations pratiquées dans le chemisage 5 sont des trous poinçonnés. 



   Une autre possibilité, pour assurer la solidarisation intime entre les plaques 2,3 renforcées par des fibres et le chemisage métallique 5, réside dans l'utilisation de plaques dont les cotes excèdent celles des faces supérieure et inférieure de l'élément à double fond ; et dans le fait que, au cours du processus de fabrication, les surfaces saillantes desdites plaques 2,3 en une matière thermoplastique renforcée par des fibres sont coudées, à l'état plastique, en direction du chemisage métallique 5 contre lequel elles sont pressées. 



   Dans les deux cas, le chemisage métallique 5 est relié, à l'élément à double fond, sans aucun adhésif supplémentaire. 



   Le matériau central employé est un matériau comportant de multiples cavités, de préférence une mousse ou un matériau alvéolé de n'importe quelle géométrie alvéolaire, consistant en des matières classiques, de préférence en du papier, du carton ou du bois, ces matières pouvant éventuellement être munies de résines, ou d'autres agents augmentant la robustesse et/ou l'inaltérabilité ; cependant, l'on peut aussi utiliser une combinaison d'un matériau alvéolé avec une mousse ou avec une substance de garnissage présentant de multiples cavités. 



  En vue d'améliorer la tenue au feu de la dalle à double fond conforme à l'invention, le matériau central 1 est ignifugé, soit du fait que la mousse ou le matériau alvéolé consiste en une matière ininflammable ; que le matériau alvéolé est imprégné ou revêtu de substances ignifuges, par exemple des sels ou 

 <Desc/Clms Page number 3> 

 des résines classiques de protection contre l'incendie ; ou bien qu'une matière ignifuge est incluse dans les alvéoles. 



  L'épaisseur du matériau central 1 est comprise entre 40 mm et 100 mm, de préférence entre 45 mm et 55 mm. 



   En tant que plaque en une matière thermoplastique renforcée par des fibres, l'on peut utiliser toutes les plaques qui consistent en une   matière synthétique thermoplastique renfor-   cée par un tissu fibreux, par une carde fibreuse ou par des fibres réparties aléatoirement dans la matrice en matière syn- 
 EMI3.1 
 thétique. Des plaques de ce type possèdent une épaisseur de 2 mm à 5 mm, préférentiellement de 2, 3 mm à 4 mm. Des exemples de matières synthétiques thermoplastiques sont les polyoléfi- nes comme, par exemple, le polyéthylène, le polypropylène et des mélanges de ces derniers, en outre des composés de polyvinyle, ainsi que des copolymères tels que 1'ABS ou le SAN, des polyamides, des polyacétals, des polycarbonates ou des polyesters.

   Des exemples de matière fibreuse sont la cellulose, les fibres d'hydrocarbures, de matières plastiques, de verre, minérales ou céramiques. 



   L'on utilise de préférence des plaques renforcées par des fibres de verre, en des polyoléfines et notamment en du polypropylène. De telles plaques existent, dans le commerce, sous la   dénomination"plaques   GMT". 



   Le revêtement 4 est relié sans aucun adhésif à la plaque considérée 2 ou 3 en une matière thermoplastique renforcée par des fibres,   c'est-à-dire   qu'il est directement ancré avec la matrice de ladite matière thermoplastique. L'on peut par conséquent employer, en tant que revêtement 4, tous les matériaux dont la face tournée vers la matière synthétique n'est pas lisse et qui, de la sorte, autorisent un ancrage mécanique avec la matri-ce en matière thermoplastique. Des exemples, à cette fin, sont des tissus, du bois, du liège, du feutre ou des matériaux minéraux, en particulier des cardes ou un granulat minéral.

   Sont toutefois également utilisables, pour constituer le revêtement 4, des matériaux composites qui présentent une surface poreuse ou rugueuse, comme par exemple du linoléum ou 

 <Desc/Clms Page number 4> 

 des dalles en pierre synthétique comportant une face   inférieu-   re en un granulat minéral ou en de l'argile expansée. 



   Les éléments à double fond conformes à l'invention peuvent présenter n'importe quelles dimensions extérieures. Des cotes préférentielles sont, respectivement, 60 cm x 60 cm ou 60 cm x 120 cm. 



   Il va de soi que de nombreuses modifications peuvent être apportées à l'élément à double fond décrit et représenté, sans sortir du cadre de l'invention.

  DOUBLE BOTTOM ACOUSTIC AND THERMAL INSULATION ELEMENT,
IN PARTICULAR FLOORING OR PARTITIONING ELEMENT
The present invention relates to an acoustic and thermal insulation element with double bottom, which can be used as a floor or partitioning element.



   From document FR-A-2 195 744, a double bottom slab of this type is known, in which a central material is covered with a plate on its upper and lower faces, a floor covering being glued on the top plate.



   The separate bonding of a covering, a protective layer or a decorative layer represents, at the stage of manufacturing such double-bottomed slabs, an additional intervention which is not economical, apart from the presence, in the slab, an additional layer of adhesive.



   According to the invention, this drawback is eliminated by providing a double bottom element of an improved type.



   The invention will now be described in more detail by way of non-limiting example, with reference to the appended drawing in which the single figure is a fragmentary perspective, with cutaway, of a double bottom element conforming to
 EMI1.1
 the invention.



   As shown in the single figure, the invention relates to a double bottom element comprising a central material 1 which is covered, on its upper and lower faces, by a respective plate 2 or 3 in a thermoplastic material reinforced with fibers, the plate upper 3 in a thermoplastic material reinforced with fibers being provided with a coating 4 which is connected, to said plate 3, without assistance. no adhesive. The sides of the central material 1, not covered with a plate, are covered with a metal jacket 5. This metal jacket 5 forms, to a certain extent, a frame which is intimately anchored with the plates reinforced by

 <Desc / Clms Page number 2>

 fibers.

   This is obtained by the fact that the liner 5 is wider than the thickness of the central material 1, and is bent at right angles to the height of the plates 2, 3 reinforced by fibers, the bent metal surfaces then resting on the marginal zones upper and lower faces of said material 1, and being capped by said plates 2,3 to which they are connected. This composite structure is improved by the fact that the metal lining 5 is perforated. Another improvement in the composite structure results from the fact that the perforations made in the liner 5 are punched holes.



   Another possibility, to ensure the intimate connection between the plates 2,3 reinforced by fibers and the metal lining 5, lies in the use of plates whose dimensions exceed those of the upper and lower faces of the double bottom element; and in the fact that, during the manufacturing process, the projecting surfaces of said plates 2,3 made of a fiber-reinforced thermoplastic material are bent, in a plastic state, in the direction of the metal lining 5 against which they are pressed.



   In both cases, the metal jacket 5 is connected to the double bottom element without any additional adhesive.



   The central material used is a material comprising multiple cavities, preferably a foam or a cellular material of any cellular geometry, consisting of conventional materials, preferably paper, cardboard or wood, these materials possibly being be provided with resins, or other agents increasing robustness and / or inalterability; however, it is also possible to use a combination of a cellular material with a foam or with a filling substance having multiple cavities.



  In order to improve the fire resistance of the double bottom slab according to the invention, the central material 1 is flame retarded, either because the foam or the cellular material consists of a non-flammable material; the cellular material is impregnated or coated with flame retardants, for example salts or

 <Desc / Clms Page number 3>

 conventional fire protection resins; or that a flame retardant material is included in the cells.



  The thickness of the central material 1 is between 40 mm and 100 mm, preferably between 45 mm and 55 mm.



   As a plate made of a fiber-reinforced thermoplastic material, it is possible to use all the plates which consist of a thermoplastic synthetic material reinforced by a fibrous fabric, by a fibrous card or by fibers distributed randomly in the matrix. syn-
 EMI3.1
 aesthetic. Plates of this type have a thickness of 2 mm to 5 mm, preferably 2.3 mm to 4 mm. Examples of thermoplastic plastics are polyolefins such as, for example, polyethylene, polypropylene and mixtures thereof, in addition polyvinyl compounds, as well as copolymers such as ABS or SAN, polyamides , polyacetals, polycarbonates or polyesters.

   Examples of fibrous material are cellulose, hydrocarbon fibers, plastics, glass, minerals or ceramics.



   It is preferable to use plates reinforced with glass fibers, in polyolefins and in particular in polypropylene. Such plates exist commercially under the name "GMT plates".



   The coating 4 is connected without any adhesive to the plate considered 2 or 3 in a thermoplastic material reinforced by fibers, that is to say that it is directly anchored with the matrix of said thermoplastic material. It is therefore possible to use, as a coating 4, all the materials whose face facing the synthetic material is not smooth and which, in this way, allow mechanical anchoring with the matri-ce in thermoplastic material. Examples for this purpose are fabrics, wood, cork, felt or mineral materials, in particular carding or mineral aggregate.

   However, composite materials which have a porous or rough surface, such as for example linoleum or

 <Desc / Clms Page number 4>

 synthetic stone slabs with a bottom face made of mineral aggregate or expanded clay.



   The double bottom elements according to the invention can have any external dimensions. Preferred dimensions are, respectively, 60 cm x 60 cm or 60 cm x 120 cm.



   It goes without saying that many modifications can be made to the double bottom element described and shown, without departing from the scope of the invention.
