Abstract

In the floor tile for double floor installations, the tile core has a floor covering on its top side, a metal plate on its underside and a lipping on its peripheral edge. The peripheral edge is here provided with a groove (9) which is to receive hot-melt adhesive (3), and the metal plate (8) has an upward edge (4) which grips around the peripheral edge, reaches up to the lower rim of the groove (9) and is flush with a first lipping (7). A second lipping (2), which covers the groove (9) and a part of the upward edge (4) of the metal plate (8), is located on top of the first lipping (7).

Description

Gegenstand der Erfindung ist ein Fußbodenplatte für Doppelbodenanlagen mit einem Plattenkern, auf dessen Unterseite eine Metallplatte, auf dessen Oberseite ein Bodenbelag und auf dessen umlaufendem Rand ein Umleimer angeordnet ist.The invention relates to a floor plate for raised floor systems with a plate core, on the underside of which is a metal plate, on the top of which there is a floor covering and on the peripheral edge of which a edge band is arranged.

Fußbodenplatten der genannten Art sind aus der deutschen Gebrauchsmusterschrift G 85 02 109 bekannt.Floor panels of the type mentioned are known from the German utility model G 85 02 109.

Bei der Verwendung von Holzspanplatten oder von Platten aus mineralischem Material wie z.B. Fasergips ist die Kantenumleimung nur unbefriedrigend gelöst. Neben einer wenig guten Haftung des Umleimers auf dem umlaufenden Rand ist die Fuge zwischen Umleimer und Bodenbelag kritisch. In sie dringt mit der Zeit Feuchtigkeit ein, die den Kern zerstören kann.When using chipboard or plates made of mineral material such as The edge banding is only unsatisfactorily solved in plaster of Paris. In addition to poor adhesion of the edge band to the peripheral edge, the joint between the edge band and the floor covering is critical. Moisture penetrates into them over time, which can destroy the core.

Der Erfindung liegt demnach die Aufgabe zugrunde, eine Fußbodenplatte der eingangs genannten Art zu schaffen, deren Umleimer eine verbesserte Haftung auf dem umlaufenden Rand aufweist und bei der das Eindringen von Feuchtigkeit im Bereich der Fuge zwischen Umleimer und Bodenbelag vermieden wird.The invention is therefore based on the object to provide a floor panel of the type mentioned, the edge band has an improved adhesion to the peripheral edge and in which the penetration of moisture in the area of the joint between the edge band and the flooring is avoided.

Die Aufgabe wird durch eine Fußbodenplatte gelöst, bei der der umlaufende Rand mit mindestens einer Nut zur Aufnahme von Schmelzkleber versehen ist, die Metallplatte eine Aufkantung besitzt, die den umlaufenden Rand umfaßt, bis zur Unterkante der Nut reicht und mit einem ersten Umleimer fluchtet, und auf dem ersten Umleimer ein zweiter Umleimer angeordnet ist, der die Nut und einen Teil der Aufkantung der Metallplatte bedeckt.The object is achieved by a floor plate in which the circumferential edge is provided with at least one groove for receiving hot-melt adhesive, the metal plate has an upstand which encompasses the circumferential edge, extends to the lower edge of the groove and is flush with a first edge band, and a second edge band is arranged on the first edge band, which covers the groove and part of the upstand of the metal plate.

Der erste Umleimer kann an die Unterseite des Bodenbelages anstoßen, der zweite Umleimer deckt vorzugsweise die Kante des Bondenbelages ab. Als Umleimer kann elektrischen Strom leitendes Material aus ABS oder PVC verwendet werden. Zur Erhöhung der Biegesteifigkeit der Fußbodenplatte kann zwischen Bodenbelag und Plattenkern eine Metallplatte angeordnet sein.The first edge band can abut the underside of the floor covering, the second edge band preferably covers the edge of the bonding surface. ABS or PVC material that conducts electricity can be used as the edge band. To increase the flexural rigidity of the floor slab, a metal plate can be arranged between the floor covering and the slab core.

Die Erfindung bietet den Vorteil, daß die Fußbodenplatte auch bei Verwendung von Gipsfaserplatten oder Spanplatten minderer qualität die geforderte Biegesteifigkeit erreicht. Zum anderen können die Umleimer auf herkömmlichen Kantenanleimmaschinen verarbeitet werden.The invention has the advantage that the floor plate achieves the required bending stiffness even when using gypsum fibreboard or chipboard of poor quality. On the other hand, the edge banding can be processed on conventional edge banding machines.

Im folgenden wird die Erfindung anhand einer lediglich einen Ausführungsweg darstellenden Zeichnung näher erläutert:The invention is explained in more detail below on the basis of a drawing illustrating only one embodiment:

Die Fußbodenplatte, deren Plattenkern 5 aus Holzwerkstoff oder mineralischem Material, wie Fasergips bestehen kann, ist auf der Unterseite mit einer Metallwanne 8 (Stahl, Stahlblech verzinkt oder Aluminium) verstärkt, deren Aufkantung 4 den umlaufenden Rand des Plattenkerns umfaßt und sich bis zu einer Nut 9 erstreckt. Ferner fluchtet die Aufkantung 4 mit einem ersten Umleimer 7. Die Nut 9 dient der Aufnahme von Kleber 3, vorzugsweise Heißschmelzkleber. Auf dem ersten Umleimer 7 ist ein zweiter Umleimer 2 angeordnet, der die Nut 9 mit dem Kleber 3 sowie den Randteil der Aufkantung 4 abdeckt. Auf der Oberseite des Plattenkerns 5 ist ein Bodenbelag 1 angeordnet, der aus Metall, PVC, Textilmaterial, HPL-Material, Linoleum, Keramik, Naturstein, Kork oder Parkett bestehen kann. Bei Verwendung von nicht metallischem Bodenbelag 1 kann es zweckmäßig sein, zwischen Bodenbelag und Plattenkern ein metallisches Blech 6 anzuordnen. Als Kleber für die Umleimer 2, 7, den Bodenbelag und Metallplatten 6, 8 eignen sich alle herkömmlichen Kleber, insbesondere elektrischen Strom leitende Kleber. Der erste Umleimer 7 stößt von unten an das Blech 6 bzw. den Bodenbelag 1, während der zweite Umleimer 2 die Kante des Bodenbelages abdeckt und mit der Oberseite des Bodenbelages 1 bündig abschließt. Um statische Aufladungen des Bodenbelages 1 zur Wanne 8 abzuleiten, können die Umleimer 2, 7 leitfähig für elektrische Ladungen ausgerüstet sein.The floor plate, the plate core 5 made of wood or mineral material, such as fiber plaster, is reinforced on the underside with a metal pan 8 (steel, galvanized sheet steel or aluminum), the upstand 4 includes the circumferential edge of the plate core and up to a groove 9 extends. Furthermore, the upstand 4 is aligned with a first edge band 7. The groove 9 serves to receive adhesive 3, preferably hot-melt adhesive. On the first edge band 7, a second edge band 2 is arranged, which covers the groove 9 with the adhesive 3 and the edge part of the upstand 4. On the top of the plate core 5, a floor covering 1 is arranged, which can consist of metal, PVC, textile material, HPL material, linoleum, ceramic, natural stone, cork or parquet. When using non-metallic floor covering 1, it may be expedient to arrange a metallic sheet 6 between the floor covering and the core of the board. All conventional adhesives, in particular electrically conductive adhesives, are suitable as adhesives for the edge banding 2, 7, the floor covering and metal plates 6, 8. The first The edge band 7 abuts the sheet 6 or the floor covering 1 from below, while the second edge band 2 covers the edge of the floor covering and is flush with the top of the floor covering 1. In order to dissipate static charges on the floor covering 1 to the tub 8, the edge banding 2, 7 can be equipped to conduct electricity.
