Description
Dubbel-bodemelement.Double bottom element.
De uitvinding heeft betrekking op een dubbel-bodemelement, bestaande uit een kernmateriaal, dat aan de boven- en benedenzijde is bedekt door een vezelversterkte plaat uit een thermoplastisch materiaal, waarbij de bovenste vezelversterkte plaat bestaat uit een thermoplastisch materiaal met een bekleding. Een dergelijk dubbel-bodemelement kan als geluiddempend en warmte-isolerend bodem- of wandelement worden toegepast.The invention relates to a double bottom element, consisting of a core material, which is covered at the top and bottom by a fiber-reinforced plate of a thermoplastic material, the upper fiber-reinforced plate of a thermoplastic material with a coating. Such a double bottom element can be used as a sound-damping and heat-insulating bottom or wall element.
Een dergelijk dubbel-bodemelement is bekend uit het FR-A-2.195.744, waarbij een kernmateriaal aan de boven- en benedenzijde door een plaat is bedekt, waarbij op de bovenste plaat een vloerbedekking is gelijmd.Such a double bottom element is known from FR-A-2,195,744, in which a core material is covered at the top and bottom by a plate, with a floor covering glued to the top plate.
Het afzonderlijk oplijmen van een bedekking, zoals een beschermings- of decoratielaag, omvat een extra arbeids-stap bij de vervaardiging van dergelijke dubbe1-bodemelemen-ten, die afgezien van de extra lijmlaag in de plaat oneconomisch is.Gluing a cover separately, such as a protective or decorative layer, involves an additional work step in the manufacture of such double bottom elements, which is uneconomical apart from the additional adhesive layer in the plate.
De uitvinding beoogt een dubbel-bodemelement van de in de aanhef genoemde soort te verschaffen, waarbij dit nadeel op eenvoudige, doch niettemin doeltreffende wijze is opgeheven.The object of the invention is to provide a double bottom element of the type mentioned in the preamble, wherein this drawback is eliminated in a simple, yet effective manner.
Hiertoe bezit het dubbel-bodemelement volgens de uitvinding het kenmerk, dat de bekleding zonder lijm is verbonden met de vezelversterkte plaat uit een thermoplastisch materiaal.To this end, the double-bottom element according to the invention is characterized in that the coating is connected without glue to the fiber-reinforced plate of a thermoplastic material.
De uitvinding wordt hierna nader toegelicht aan de hand van de enige tekening, die een uitvoeringsvoorbeeld van het dubbel-bodemelement volgens de uitvinding toont.The invention is explained in more detail below with reference to the only drawing, which shows an exemplary embodiment of the double bottom element according to the invention.
Het in de tekening weergegeven dubbel-bodemelement bestaat uit een kernmateriaal 1, dat aan de boven- en benedenzijde is bedekt door een vezelversterkte plaat uit een thermoplastisch materiaal 2 resp. 3. De bovenste vezelversterkte plaat uit thermoplastisch materiaal 3 is voorzien van een bekleding 4, die zonder lijm met de vezelversterkte plaat uit thermoplastisch materiaal is verbonden.The double bottom element shown in the drawing consists of a core material 1, which is covered at the top and bottom by a fiber-reinforced plate made of a thermoplastic material 2 and 4, respectively. 3. The top fiber-reinforced plate of thermoplastic material 3 is provided with a coating 4, which is bonded without glue to the fiber-reinforced plate of thermoplastic material.
In de getoonde uitvoeringsvorm zijn de niet met een plaat bedekte zijden van het kernmateriaal 1 bedekt met een metaalbekleding 5. De metaalbekleding vormt als het ware een raam, dat innig is verankerd met de vezelversterkte platen. Deze innige verankering wordt bereikt door het feit, dat de metaalbekleding breder is dan de dikte van het kernmateriaal en ter hoogte van de vezelversterkte platen rechthoekig is omgezet, waarbij de omgezette metaalvlakken op de aan de boven- en benedenzijde gelegen randzones van het kernmateriaal liggen en door de vezelversterkte platen worden bedekt en hiermee zijn verbonden. De verbinding wordt verder verbeterd, indien de metalen bekleding van gaten is voorzien. Een verdere verbetering van de verbinding wordt verkregen, indien de gaten in de metalen bekleding bestaan uit doorscheurgaten.In the embodiment shown, the non-plate-covered sides of the core material 1 are covered with a metal coating 5. The metal coating forms, as it were, a window which is anchored intimately with the fiber-reinforced plates. This intimate anchoring is achieved by the fact that the metal coating is wider than the thickness of the core material and is rectangularly converted at the height of the fiber-reinforced plates, the converted metal surfaces lying on the top and bottom edge zones of the core material and plates are covered and bonded to them by the fiber-reinforced plates. The connection is further improved if the metal cladding is provided with holes. A further improvement of the connection is obtained if the holes in the metal cladding consist of tear-through holes.
Een andere mogelijkheid, om een stevige verbinding tussen de vezelversterkte platen en de metaalbekleding te verkrijgen, bestaat uit de toepassing van platen, die groter zijn dan het aan de boven- en benedenzijde gelegen oppervlak van het dubbel-bodemelement, waarbij de uitstekende vlakken van de vezelversterkte platen uit thermoplastisch materiaal tijdens het vervaardigingsproces in de plastische toestand in de richting van de metaalbekleding worden omgezet en tegen deze metaalbekleding worden geperst.Another possibility, in order to obtain a firm connection between the fiber-reinforced plates and the metal cladding, is the use of plates that are larger than the top and bottom surface of the double-bottom element, whereby the protruding surfaces of the fiber-reinforced plates of thermoplastic material are converted in the plastic state in the direction of the metal coating during the manufacturing process and are pressed against this metal coating.
In beide gevallen is de metaalbekleding zonder extra lijm verbonden met het dubbel-bodemelement.In both cases, the metal cladding is connected to the double bottom element without additional glue.
Het toegepaste kernmateriaal bestaat uit een veel holle ruimten bezittend materiaal, bij voorkeur schuim of een honingraatelement met een willekeurige honingraatgeometrie uit gebruikelijke materialen, bij voorkeur uit papier, karton of hout, waarbij deze materialen eventueel kunnen zijn voorzien van harsen of andere de stevigheid en/of bestendigheid verhogende middelen; echter ook een combinatie van een honingraatelement met schuim of een van veel holle ruimten voorziene vulling is mogelijk. Teneinde de vuurvastheid van de dubbel-bodemplaat volgens de uitvinding te verbeteren is het kernmateriaal vlamwerend uitgevoerd, hetzij door het feit dat het schuim of het honingraatmateriaal uit een vlambestendig materiaal bestaat, of dat het honingraatmateriaal met vlamwerende substanties, zoals gebruikelijke vuurbeschermingszouten of -harsen is geïmpregneerd of bekleed, of door het feit, dat in de honingraatkamers vlamwerend materiaal is opgesloten. De dikte van het kernmateriaal ligt in de buurt van 40 tot 100 mm, bij voorkeur in de buurt van 45 tot 55 mm.The core material used consists of a material having a lot of cavities, preferably foam or a honeycomb element with an arbitrary honeycomb geometry of usual materials, preferably of paper, cardboard or wood, these materials possibly being provided with resins or other the strength and / or or constancy enhancers; however, a combination of a honeycomb element with foam or a filling with many cavities is also possible. In order to improve the refractoriness of the double-bottom plate according to the invention, the core material is flame-resistant, either due to the fact that the foam or honeycomb material consists of a flame-resistant material, or that the honeycomb material is made of flame-resistant substances, such as conventional fire protection salts or resins. impregnated or coated, or due to the fact that flame-resistant material is enclosed in the honeycomb chambers. The thickness of the core material is in the range of 40 to 100 mm, preferably in the range of 45 to 55 mm.
Als vezelversterkte plaat uit thermoplastisch materiaal zijn alle platen toepasbaar, die uit een thermoplastische kunststof bestaan die met een vezelweefsel, vezelvlies of met statistisch in de kunststofmatrix verdeelde vezels is versterkt. Dergelijke platen bezitten een dikte van 2 tot 5 mm, bij voorkeur van 2,3 tot 4 mm. Voorbeelden voor thermoplastische kunststoffen vormen polyolefinen, zoals bijvoorbeeld polyethyleen, polypropyleen en mengsels daarvan, verder polyvi-nylverbindingen alsmede copolymerisaten zoals ABS of SAN, polyamide, polyacetalen, polycarbonaten of polyester. Voorbeelden voor het vezelmateriaal vormen cellulose, koolstof-, kunststof-, glas-, mineraal- of keramische vezels.All plates can be used as a fiber-reinforced plate of thermoplastic material, which consist of a thermoplastic plastic which is reinforced with a fiber fabric, non-woven fabric or with fibers distributed statistically in the plastic matrix. Such plates have a thickness of 2 to 5 mm, preferably 2.3 to 4 mm. Examples for thermoplastic plastics are polyolefins such as, for example, polyethylene, polypropylene and mixtures thereof, further polyvinyl compounds as well as copolymers such as ABS or SAN, polyamide, polyacetals, polycarbonates or polyester. Examples for the fiber material are cellulose, carbon, plastic, glass, mineral or ceramic fibers.
Bij voorkeur worden glasvezelversterkte platen uit polyolefinen toegepast, in het bijzonder uit polypropyleen. Dergelijke platen zijn als zogenaamde GMT-platen in de handel.Glass-fiber reinforced plates made of polyolefins are used, in particular polypropylene. Such plates are commercially available as so-called GMT plates.
De bekleding is zonder lijm verbonden met de vezel-versterkte plaat uit thermoplastisch materiaal, d.w.z. dat ze rechtstreeks in de matrix van de thermoplast is verankerd. Derhalve zijn als bekleding alle materialen geschikt, waarvan de naar de kunststof toegekeerde zijde niet glad is, en derhalve een mechanische verankering in de thermoplastische kunststofmatrix mogelijk maken. Voorbeelden hiervan vormen weefsels, hout, kurk, vilt of minerale materialen, in het bijzonder tegels of mineraal-granulaat. Als bekleding zijn echter ook samengestelde materialen toepasbaar, die een poreus of ruw oppervlak bezitten, zoals bijvoorbeeld linoleum of kunststeenplaten met een onderzijde uit mineraal-granulaat of poreuze gebrande klei.The coating is bonded without glue to the fiber-reinforced thermoplastic sheet, i.e. it is anchored directly in the matrix of the thermoplastic. Therefore, all materials whose side facing the plastic is not smooth are suitable as a coating and therefore permit mechanical anchoring in the thermoplastic plastic matrix. Examples of this are fabrics, wood, cork, felt or mineral materials, in particular tiles or mineral granulate. However, it is also possible to use composite materials which have a porous or rough surface, such as, for example, linoleum or artificial stone slabs with a underside of mineral granulate or porous burnt clay.
De dubbel-bodemelementen volgens de uitvinding kunnen willekeurige uitwendige afmetingen bezitten. De voorkeur genietende afmetingen zijn 60 x 60 cm resp. 60 x 120 cm.The double bottom elements according to the invention can have any external dimensions. Preferred dimensions are 60 x 60 cm resp. 60 x 120 cm.
