Description

Die Erfindung bezieht sich auf eine Fußbodenplatte für Doppelböden, die in einem umlaufenden Rahmen gehalten und an den Ecken auf entsprechenden Doppelbödenstützen auflegbar ist.The invention relates to a floor plate for raised floors, which is held in a circumferential frame and can be placed on corresponding raised floor supports at the corners.

Eine derartige Fußbodenplatte ist aus der FR-A-2 213393 bekannt. Dabei weist die Bodenplatte einen rechteckigen oder quadratischen Rahmen aus einem U-förmigen Profil mit einem längeren außenliegenden und einem kürzeren innenliegenden Schenkel auf, in das die Bodenplatte konstanter Dicke so eingelegt ist, daß sie im wesentlichen vom inneren, kürzeren Schenkel des U-förmigen Profils abgestützt wird und an ihrem Außenumfang von der Innenseite des längeren Schenkels begrenzt und gegenüber diesem längeren Schenkel zusätzlich über horizontale Bolzen bzw. Verschraubungen arretiert ist. Eine derartig gestaltete Bodenplatte weist zwar eine höhere Tragfähigkeit auf, als wenn die eigentliche Trägerplatte direkt auf die Doppelbodenstützen aufgelegt wäre. Deren Tragfähigkeit ist jedoch unzureichend dann, wenn eine solche Bodenplatte im Schwerlast- oder im Fahrbereich eingesetzt werden soll, d.h. wenn diese Platten ohne Verformung auch von Lastwagen befahren werden sollen oder zur Abstützung schwergewichtiger Lasten dienen.Such a floor slab is known from FR-A-2 213393. The base plate has a rectangular or square frame made of a U-shaped profile with a longer outer leg and a shorter inner leg, in which the base plate of constant thickness is inserted so that it is essentially from the inner, shorter leg of the U-shaped profile is supported and limited on its outer circumference by the inside of the longer leg and is additionally locked against this longer leg by means of horizontal bolts or screw connections. A base plate designed in this way has a higher load-bearing capacity than if the actual support plate were placed directly on the raised floor supports. However, their load-bearing capacity is insufficient if such a base plate is to be used in the heavy load or driving area, i.e. if these plates are to be driven on by trucks without deformation or are used to support heavy loads.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Fußbodenplatte für einen Doppelboden zu schaffen, die insbesondere im Schwerlast- und im Fahrbereich eingesetzt werden kann und die dabei zum einen hinsichtlich der Anpassung an Belastung und Gewichtserfordernis variabel ist und zum anderen auf einfache Weise eine Scheibenausbildung der Doppelbodenebene ermöglicht.The invention is therefore based on the object to provide a floor panel for a raised floor, which can be used in particular in heavy-duty and driving areas and which is variable on the one hand with regard to the adaptation to load and weight requirement and on the other hand a simple formation of a disc Raised floor level allows.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß der Rahmen aus einem L-förmigen, metallischen Hohlprofil besteht, auf dessem nach innen vorspringenden Ansatz eine am Außenumfang entsprechend eingezogene Trägerplatte angenähert gleicher Höhe wie die des Hohlprofils eingelegt ist, und daß die Oberseite sowohl des Rahmens als auch der Trägerplatte vollflächig von einer weiteren, mit dem Rahmen und derTrägerplatte verklebten Bodenplatte abgedeckt ist.To achieve this object it is provided according to the invention that the frame consists of an L-shaped, metallic hollow profile, on the inwardly projecting approach of which a correspondingly retracted support plate on the outer circumference is inserted approximately the same height as that of the hollow profile, and that the top of both the frame as well as the support plate is completely covered by a further base plate glued to the frame and the support plate.

Durch diese Gestaltung als geschlossenes Hohlprofil mit L-förmigen Querschnitt weist dieser Rahmen eine erheblich größere Steifigkeit und Belastbarkeit als herkömmliche Abstützprofile auf. Da darüberhinaus die in dem Rahmen einzulegende Trägerplatte die gleiche Höhe wie das gesamte Hohlprofil aufweist, kann sie damit hohen Biegelasten, die ihr Maximum im Zentrum der Platte im Bereich des größten Abstandes von der umlaufenden Abstützung aufweisen, sehr viel besser standhalten. Darüberhinaus ist eine gesonderte Verspannung der Trägerplatte gegen den Rahmen nicht mehr erforderlich.Due to this design as a closed hollow profile with an L-shaped cross-section, this frame has a considerably greater rigidity and resilience than conventional support profiles. In addition, since the carrier plate to be inserted in the frame has the same height as the entire hollow profile, it can thus withstand much higher bending loads, which have their maximum in the center of the plate in the area of the greatest distance from the circumferential support, much better. In addition, a separate bracing of the support plate against the frame is no longer necessary.

Zweckmäßig ist es dabei, wenn das Hohlprofil an seiner innenliegenden Oberkante eine nach oben ragende Arretierungsnase aufweist.It is useful if the hollow profile has an upwardly projecting locking lug on its inner upper edge.

Ferner kann der Rahmen sowohl an seiner innenliegenden Ober- als auch Unterkante je einen nach innen ragenden Steg aufweisen.Furthermore, the frame can have an inwardly projecting web on both its inner upper and lower edge.

Die mit dem Rahmen und der Trägerplatte verklebte Bodenplatte besteht zweckmäßigerweise aus einem vorkonfektionierten Teppichbodenträgerelement. Dadurch ist es möglich abgenutzte oder beschädigte Teile einer derartigen Fußbodenplatte leicht auszuwechseln, ohne die gesamte Platte ersetzen zu müssen.The base plate glued to the frame and the support plate expediently consists of a prefabricated carpet support element. This makes it possible to easily replace worn or damaged parts of such a floor panel without having to replace the entire panel.

Weiterhin ist es besonders zweckmäßig, wenn die Fußbodenplatten im Eckbereich auf ihrer Unterseite Ausnehmungen zum Eingriff von Halterungsmittel des Auflagetellers der Doppelbodenstützen aufweisen. Diese Halterungsmittel können dabei durch hochgebogene Stege des Auflagetellers oder aber durch aus dem Auflageteller nach oben ragende Stifte gebildet sein. Durch ein derartiges, einfaches Arretieren der einzelnen Platten ist damit eine Scheibenausbildung der Doppelbodenebene ermöglicht.Furthermore, it is particularly expedient if the floor panels in the corner region have recesses on their underside for the engagement of holding means of the support plate of the raised floor supports. These holding means can be formed by raised webs of the support plate or by pins protruding upwards from the support plate. Such a simple locking of the individual plates enables the double floor level to be formed in a pane.

The structure and mode of operation of exemplary embodiments according to the invention are explained in more detail with reference to a schematic drawing. Show
  • 1 is a perspective view of a floor slab and the associated raised floor supports,
  • 2 shows a partial cross section through a floor plate with an L-shaped frame,
  • 3 shows a partial cross section through the floor plate with an L-shaped frame with locking lug,
  • 4 shows a partial cross section through a floor plate with a frame with inwardly projecting webs,

  • Fig. 6 is a plan view in partial section of the locking device according to Fig. 5 and
  • Figure 7 is a partial cross-section through a floor panel with a pin lock.

Wie aus Fig. 1 zu ersehen ist, weist eine entsprechende Fußbodenplatte 1 im allgemeinen quadratischen Querschnitt auf und ist auf 4 Doppelbodenstützen 2 aufgelagert, die im einzelnen dann jeweils aneinanderstoßend die Eckpunkte von 4 derartigen Fußbodenplatten tragen.As can be seen from FIG. 1, a corresponding floor plate 1 has a generally square cross section and is supported on 4 raised floor supports 2, which then each bear the corner points of 4 such floor plates in abutting manner.

Die Tragfähigkeit derartiger Platten ist dabei im wesentlichen bedingt durch die Belastbarkeit im Randbereich. Um dabei diese Platten auch für hohe Belastungen im Schwerlastbereich oder im Fahrbereich zu ertüchtigen, ist nach Fig. 2 am Außenumfang der Fußbodenplatte 1 ein lastabtragender Rahmen 3 in Form eines L-förmigen Hohlprofils, z.B. aus Aluminium oder Stahl, vorgesehen, auf dessen nach innen vorspringenden Ansatz 4 eine am Außenumfang entsprechend geformte Trägerplatte 5 aufgelegt ist. Den Rahmen 3 und die Trägerplatte 5 überdeckend, ist auf der Oberseite eine weitere Bodenplatte 6 angeordnet, die über eine lösbare Kleberschicht 7 mit dem Rahmen 3 und der Trägerplatte 5 verbunden ist. Diese Bodenplatte 6 ist zweckmäßigerweise als vorkonfektioniertes Teppichbodenträgerelement ausgebildet und auf ihrer Oberseite bereits mit einem entsprechenden begehbaren Teppichbelag ausgerüstet.The load-bearing capacity of such panels is essentially due to the load-bearing capacity in the edge area. In order to strengthen these plates even for high loads in the heavy load area or in the driving area, a load-bearing frame 3 in the form of an L-shaped hollow profile, for example made of aluminum or steel, is provided on the outer circumference of the floor plate 1, on the inside of which projecting approach 4 a correspondingly shaped carrier plate 5 is placed on the outer circumference. Covering the frame 3 and the carrier plate 5, a further base plate 6 is arranged on the top, which is connected to the frame 3 and the carrier plate 5 via a releasable adhesive layer 7. This base plate 6 is expediently a prefabricated carpet support element trained and already equipped with an appropriate walk-in carpet on the top.

Eine derartige Fußbodenplatte 1 ist somit für höchste Belastungen geeignet und bietet ein Optimum hinsichtlich der Anpassung an die jeweiligen Anforderungen, wobei insbesondere die Materialwahl in weiten Grenzen variiert werden kann. So ist es beispielsweise möglich, aus brandtechnischen Gründen den Rahmen 3 mit einem nicht brennbaren Füllstoff 9, z.B. Gips, auszufüllen. Die Trägerplatte 5 kann aus einer Spanplatte oder einer Gipsfaserplatte oder einem anderen, nicht brennbaren Material gefertigt sein, ebenso wie das Teppichbodenträgerelement 6, das z.B. aus einem Faserzement bestehen kann.Such a floor slab 1 is therefore suitable for the highest loads and offers an optimum in terms of adaptation to the respective requirements, the choice of material in particular being able to be varied within wide limits. For example, for fire-related reasons, it is possible to frame 3 with a non-combustible filler 9, e.g. Plaster to fill out. The carrier plate 5 can be made of a chipboard or a gypsum fiberboard or another non-combustible material, as can the carpet carrier element 6, which e.g. can consist of a fiber cement.

Da die Fußbodenplatte 1 aufgrund ihres stabilen Rahmens 3 keine Kriech- oder Schwindeigenschaften mehr aufweist, besteht auch ein erheblicher Vorteil in der gewählten Ausführungsform darin, daß die Platte sinnvoll teilerneuert werden kann. Hierzu wird der zwischen dem Teppichbodenträgerelement 6 und der Trägerplatte 5 vorgesehene Spezialkleber 7 gelöst und entfernt, so daß dann das Element 6 und/oder die Trägerplatte 5 ausgetauscht und erneuert werden kann. Da darüberhinaus das Teppichbodenträgerelement 6 keine tragende Funktion mehr übernimmt, ist es möglich, darin entsprechende Nutungen 10 vorzunehmen, um evtl. erforderliche Steuerleitungen 11 unterzubringen.Since the floor plate 1 no longer has any creeping or shrinking properties due to its stable frame 3, there is also a considerable advantage in the selected embodiment that the plate can be meaningfully partially renewed. For this purpose, the special adhesive 7 provided between the carpet support element 6 and the support plate 5 is loosened and removed, so that the element 6 and / or the support plate 5 can then be exchanged and renewed. In addition, since the carpet support element 6 no longer assumes a load-bearing function, it is possible to make corresponding grooves 10 in order to accommodate any control lines 11 that may be required.

In Fig. 3 ist ein Rahmen 3 entsprechend Fig. 2 dargestellt, der jedoch zur Verbesserung der Arretierung der Trägerplatte 5 am innenliegenden Ansatz 4 des Rahmens 3 zusätzlich noch eine nach oben ragende Arretierungsnase 12 aufweist.FIG. 3 shows a frame 3 corresponding to FIG. 2, which, however, additionally has an upwardly projecting locking lug 12 in order to improve the locking of the carrier plate 5 on the inner extension 4 of the frame 3.

Eine weitere zweckmäßige Ausgestaltung eines derartigen Rahmens ist in Fig. 4 dargestellt. Danach besteht der Rahmen aus einem angenähert rechteckigen Hohlprofil 15, der an seiner innenliegenden Ober- und Unterkante je einen nach innen ragenden Steg 16 und 17 aufweist, in den die entsprechende Trägerplatte 5 eingesetzt werden kann.Another expedient embodiment of such a frame is shown in FIG. 4. Thereafter, the frame consists of an approximately rectangular hollow profile 15, which has an inwardly projecting web 16 and 17 on its inner upper and lower edge, into which the corresponding carrier plate 5 can be inserted.

Zur maßgenauen Festlegung der Fußbodenplatten 1 auf den Doppelbodenstützen 2 sind - wie aus Fig. 5 und 6 zu ersehen ist - im Eckbereich auf der Unterseite des Rahmens 3 Ausnehmungen 20 vorgesehen, in die hochgebogene Stege 21 des Auflagetellers 22 der Doppelbodenstützen 2 hineinragen. Dabei ist aus der Aufsicht nach Fig. 6 die angenähert kreuzförmige Ausbildung des Auflagetellers 22 mit den hochgebogenen Stegen 21 an den kreuzförmigen Ansätzen 23 zu erkennen. Eine derartige Arretierung ermöglicht ein paßgenaues Einsetzen der einzelnen Fußbodenplatten 1, so daß dadurch auf einfache Weise eine Scheibenausbildung der Doppelbodenebene ermöglicht ist.5 and 6, recesses 20 are provided in the corner area on the underside of the frame 3, into which bent webs 21 of the support plate 22 of the raised floor supports 2 protrude for the dimensionally accurate fixing of the floor panels 1 on the raised floor supports 2. 6, the approximately cruciform design of the support plate 22 with the bent webs 21 on the cruciform projections 23 can be seen. Such a lock enables a precise insertion of the individual floor panels 1, so that a disk formation of the raised floor level is made possible in a simple manner.

Eine andere Möglichkeit der Festlegung von Fußbodenplatten ergibt sich aus Fig. 7 in Verbindung mit Fig. 6. Wie man aus Fig. 6 ersieht, können in den Eckbereichen der Auflageteller 22 auch Bohrungen 25 vorgesehen sein, in die-wie aus Fig. 7 zu ersehen ist - von unten nach oben herausragende Stifte 26 eingesetzt sind. Diese Stifte 26 ragen dann in entsprechende Löcher 27 im Eckbereich der Fußbodenplatte 1 und gewährleisten damit in gleicher Weise eine sichere Arretierung derselben.Another possibility of fixing floor panels results from FIG. 7 in conjunction with FIG. 6. As can be seen from FIG. 6, bores 25 can also be provided in the corner regions of the support plates 22, into which — as in FIG. 7 seen - protruding pins 26 are inserted from bottom to top. These pins 26 then protrude into corresponding holes 27 in the corner region of the floor plate 1 and thus ensure a secure locking of the same in the same way.

Insgesamt ergibt sich also eine Fußbodenplatte, die hohe Belastungen aufnehmen kann und die gleichzeitig so aufgebaut ist, daß abgenutzte oder beschädigte Teile leicht ausgewechselt werden können. Durch die darüberhinaus vorgesehene Art der Arretierung der einzelnen Platten ist ein besonders stabiler Aufbau des gesamten Doppelbodens mit Scheibenwirkung gegeben.All in all, there is a floor panel that can absorb high loads and that is constructed at the same time so that worn or damaged parts can be easily replaced. The type of locking of the individual plates, which is also provided, provides a particularly stable construction of the entire double floor with a disc effect.
