Abstract

The component assembly for interior fittings in a building, and especially to give stair steps, is a board in a sandwich structure. The core layer (K) is a chipboard, flanked by hard boards (H). The outer surfaces are covered by laminated layers (L1,L2). The core is composed of three chipboard layers. The outer layers are a high density fiberboard (HDF). The laminate is a continuous lamination. The layers are bonded together by an adhesive.

Description

Die Erfindung betrifft ein Bauelement für den Innenausbau, insbesondere für die Herstellung von Treppenstufen.The invention relates to a component for interior work, in particular for the production of steps.

Das Bauelement zeichnet sich durch eine hohe Festigkeit aus und ermöglicht deshalb die Verwendung als Material für Treppenstufen. Insbesondere für freitragende Treppen ist es erforderlich, Treppenstufen aus hochfestem Material herzustellen. Bei Holzausführungen werden deshalb für derartige Anwendungen Multiplexhölzer in Ausführungen mit 21 und mehr Schichten eingesetzt. Die daraus hergestellten Treppen sind deshalb sehr kostenaufwendig. The component is characterized by high strength and enables hence the use as material for stairs. Especially for cantilevered stairs it is necessary to use stairs made of high-strength material manufacture. In wood versions are therefore used for such applications Multiplex wood used in versions with 21 and more layers. The Stairs made from it are therefore very expensive.  

Das erfindungsgemäße Bauelement ist darüber hinaus für vielfältige Anwendungen, bei denen hochfeste Bauelemente mit holzähnlichen Strukturen benötigt werden, geeignet.The component according to the invention is also diverse Applications in which high-strength components with wood-like structures are needed.

Im Stand der Technik sind verschiedene Möglichkeiten bekannt, kostengünstige, holzähnliche Platten herzustellen. Bevorzugt werden hierzu Pressspanplatten verwendet, bei denen durch Verstärkungsmittel gesteigerte Festigkeitswerten erzeugt werden.Various possibilities are known in the prior art, To produce inexpensive, wood-like panels. Are preferred for this Pressed chipboard used in which increased by reinforcing agents Strength values are generated.

So ist nach DE 35 08 438 A1 eine gepresste Mehrschichtplatte und ein Verfahren zu ihrer Herstellung bekannt, die für Fußböden, Arbeitsplatten für Küchen u. a. Geeignet ist. Dabei werden Trägerschichten mit ausgehärteten Deckschichten versehen, die aus mindestens einer mit Duroplast, vorzugsweise Melaminharz oder Melaminharzkondensatharz getränkten Papierbahn bestehen. Mit dieser Möglichkeit kann die Mehrschichtplatte mit einem Dekor versehen werden. Eine hohe Festigkeit wird damit jedoch nicht erzielt.According to DE 35 08 438 A1, a pressed multilayer board and a Process for their preparation known for floors, countertops for Kitchens and a. Suitable is. Carrier layers are cured Cover layers, which are made of at least one with thermoset, preferably Melamine resin or melamine resin condensate resin impregnated paper web. With this option, the multilayer board can be decorated become. However, high strength is not achieved with this.

Ferner ist in DE 84 30 185 U1 eine Fussbodenplatte für Doppelböden in schwerentflammbarer Ausführung angegeben, die als Sandwichplatte aus einer hochverdichteten Spanplatte mit einer unterseitigen Platte aus mineralisch gebundenen Fasern besteht. Nachteilig ist hierbei, dass die für Treppenstufen erforderliche Festigkeit sowie die ästhetischen Anforderungen nicht erfüllt werden können.Furthermore, in DE 84 30 185 U1 a floor plate for raised floors in Flame retardant version specified as a sandwich panel made from a high-density chipboard with a mineral board on the underside bound fibers. The disadvantage here is that for stairs required strength and aesthetic requirements are not met can be.

Der Erfindung liegt die Aufgabe zugrunde, ein Bauelement der eingangs genannten Art anzugeben, das sich durch eine hohe Festigkeit auszeichnet und mit geringem Kostenaufwand hergestellt werden kann. The invention has for its object a component of the beginning specified type, which is characterized by a high strength and can be produced at low cost.  

Erfindungsgemäß gelingt die Lösung der Aufgabe mit einem Bauelement, welches die im Patentanspruch 1 angegebenen Merkmale enthält.According to the invention, the object is achieved with one component, which contains the features specified in claim 1.

Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.Advantageous refinements are specified in the subclaims.

Das erfindungsgemäße Bauelement zeichnet sich dadurch aus, dass es kostengünstig hergestellt werden kann und eine hohe Festigkeit aufweist. Es verfügt sowohl über eine große Abriebfestigkeit als auch große Biegesteifigkeit. Es kann aus diesem Grunde vorteilhaft für die Gestaltung von Treppen eingesetzt werden und ermöglicht hierbei auch den Einsatz für freitragende Treppen. Diese können kostengünstig und mit hoher Lebensdauer gefertigt werden. Besonders hervorzuheben ist der ausgezeichnete ästhetische Eindruck, der mit einem aus einer erfindungsgemäßen Verbundplatte gefertigten Bauteil erzielt werden kann.The component according to the invention is characterized in that it can be produced inexpensively and has a high strength. It has both great abrasion resistance and great Flexural strength. For this reason, it can be beneficial for the design of Stairs are used and also enables use for cantilevered stairs. These can be inexpensive and have a long service life are manufactured. Of particular note is the excellent aesthetic Impression with a composite panel according to the invention manufactured component can be achieved.

Die Erfindung wird im Folgenden an einem Ausführungsbeispiel näher erläutert. Das Beispiel beschreibt ein für die Herstellung von Treppenstufen im Inneren von Gebäuden besonders geeignetes Bauelement. In der zugehörigen Zeichnung zeigt:The invention is explained in more detail below using an exemplary embodiment. The example describes one for the production of stairs inside Building element particularly suitable for buildings. In the associated Drawing shows:

Fig. 1 einen Schnitt durch die erfindungsgemäße Platte. Fig. 1 shows a section through the plate according to the invention.

In der Figur ist eine Platte dargestellt, die aus einem Sandwichplattenelement besteht, dessen Kernschicht K eine Dicke von 35 bis 55 mm aufweist, für bevorzugte Ausführungen werden Dicken von 38 mm sowie von 49 mm verwendet. Oberhalb und unterhalb der Kernschicht K sind zweischichtige Beläge angebracht, die jeweils aus einer 3 mm dicken hochverdichteten Faserplatte (so genannte HDF-Hartplatte) und einer 0,6 mm starken kontinuierlich hergestellten Laminatschicht (so genannte CPL-Laminatschicht) bestehen. Die einzelnen Schichten sind miteinander verklebt. Durch die Sandwichbauweise wird bei geringem Gewicht eine hohe Festigkeit erzielt und gewährleistet, dass ein Verziehen des Bauelementes infolge von Temperatur- oder Feuchtigkeitseinflüssen weitestgehend verhindert wird. In the figure, a plate is shown, which consists of a sandwich panel element exists, the core layer K has a thickness of 35 to 55 mm for preferred versions are thicknesses of 38 mm and 49 mm used. Above and below the core layer K are two layers Coverings attached, each of a 3 mm thick highly compressed Fiberboard (so-called HDF hardboard) and a 0.6 mm thick continuously produced laminate layer (so-called CPL laminate layer) consist. The individual layers are glued together. Through the  Sandwich construction is achieved with low weight and high strength ensures that warping of the component due to temperature or the influence of moisture is largely prevented.
