Description
Die Erfindung betrifft Platten, insbesondere Bodenplatten für einen Hohlraumboden, nach dem Oberbegriff des Anspruchs 1. Aus
Der Erfindung liegt die Aufgabe zugrunde, eine Verzahnung der.Bodenplatten so auszubilden, dass beim Verlegen des Bodens ein Versatz an der Oberfläche der Platten relativ zueinander minimiert bzw. verhindert wird, auch wenn die einzelnen Bodenplatten stirnseitig nicht dicht aneinander liegen und die Verzahnung schräge Zahn- und Nutflanken aufweist.The invention has for its object to form a toothing der.Bodenplatten so that when laying the soil an offset on the surface of the plates is minimized or prevented relative to each other, even if the individual floor panels frontally not close to each other and the teeth oblique tooth - Has and groove edges.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Dadurch, dass an wenigstens einem Führungszahn der Verzahnung ein Neigungswinkel der Zahnflanken wenigstens abschnittsweise kleiner als der Neigungswinkel der übrigen Zahnflanken vorgesehen ist, wird ein möglicher Versatz benachbarter Platten senkrecht zur Plattenoberfläche minimiert bzw ausgeschaltet, auch wenn die beiden Platten stirnseitig nicht dicht aneinander liegen, weil der flache Neigungswinkel der Flanken des Führungszahns in Verbindung mit einer entsprechend geformten Flanke an einer Führungsnut nur ein minimales Spiel zwischen Zahnflanke und Nutflanke zulässt, auch wenn an den anderen Zähnen ein größerer Abstand zwischen den benachbarten Flanken vorhanden ist.This object is achieved by the features of claim 1. Due to the fact that an angle of inclination of the tooth flanks is at least partially smaller than the inclination angle of the remaining tooth flanks provided on at least one guide tooth of the teeth, a possible offset of adjacent plates is minimized or turned off perpendicular to the plate surface, even if the two plates are not close to each other, because the flat angle of inclination of the flanks of the guide tooth in conjunction with a correspondingly shaped flank on a guide groove only allows minimal play between tooth flank and groove flank, even if there is a greater distance between the adjacent flanks on the other teeth.

An der Bodenplatte 1 sind zwei im Querschnitt etwa trapezförmige Zähne 1.1 und 1.2 ausgebildet, deren Zahnflanken 1.1a und 1.2a einen Winkel von beispielsweise 15° zur Oberfläche 1a der Platte aufweisen. Zwischen den beiden Zähnen 1.1 und 1.2 ist ein Führungszahn 1.3 ausgebildet, dessen Flanken bei dem dargestellten Ausführungsbeispiel auf dem innen liegenden Abschnitt 1.3a einen Neigungswinkel von etwa 2° und auf einem äußeren Abschnitt 1.3b einen Neigungswinkel von beispielsweise etwa 19° aufweisen.On the bottom plate 1, two approximately trapezoidal in cross-section teeth 1.1 and 1.2 are formed, the tooth flanks 1.1a and 1.2a have an angle of for example 15 ° to the surface 1a of the plate.

In entsprechender Weise ist am Führungszahn 1.3 der äußere Flankenabschnitt 1.3b und der innere Flankenabschnitt 2.3b an der Führungsnut über eine Höhen- bzw. Tiefenabmessung von 2,1 mm ausgebildet.The inner flank section 1.3a on the guide tooth 1.3 and the outer flank section 2.3a on the guide groove 2.3 is formed in the illustrated embodiment over half of the tooth height, which is 2.1 mm in the illustrated embodiment. In a corresponding manner, the outer flank section 1.3b and the inner flank section 2.3b on the guide tooth 1.3 are formed on the guide groove over a height or depth dimension of 2.1 mm.
Die dargestellte Ausführungsform mit vergrößerter Neigung des äußeren Flankenabschnitts 1.3b am Führungszahn erleichtert den Eingriff an der benachbarten Platte. Vorzugsweise werden die verzahnten Stirnflächen der Bodenplatten 1 und 2 mittels eines Klebemittels miteinander verklebt. Als vorteilhaft hat sich ein Klebemittel erwiesen, das eine kurze Abbindezeit hat und durch seine quellende Wirkung eine schnelle Belastbarkeit des Bodens gewährleistet. Die Verzahnung ist vorzugsweise so ausgebildet, dass sich im Eingriffszustand nach
Die Dicke der Bodenplatten kann 40 - 60 mm bei einem Kantenmaß von z. B. 600 x 600 mm oder 600 x 1200 mm betragen. Das für die Bodenplatten verwendete Material besteht vorzugsweise aus Gipsfasermaterial, das aus 90 - 97 % Recycling-Produkten wie Altpapier bestehen kann. Vorzugsweise werden Bodenplatten aus Kalziumsulfat verwendet. Es können aber auch andere Materialien für die beschriebenen Bodenplatten verwendet werden. Bevorzugt wird eine Mischung aus Kraftpapier und Gips bzw. Gipsfasermaterial.The thickness of the bottom plates can be 40 - 60 mm with an edge dimension of z. B. 600 x 600 mm or 600 x 1200 mm. The material used for the floor panels is preferably gypsum fiber material, which may consist of 90-97% recycled products such as waste paper. Preferably, bottom plates of calcium sulfate are used. However, other materials for the described floor panels can be used. Preference is given to a mixture of kraft paper and gypsum or gypsum fiber material.
Die Dichte des verwendeten Materials beträgt 1250 bis 1800 kg/m3, vorzugsweise 1750 kg/m3.The density of the material used is 1250 to 1800 kg / m 3 , preferably 1750 kg / m 3 .
Die Bodenplatten 1 und 2 sind vorzugsweise quadratisch ausgebildet, wobei das Verzahnungsprofil der Bodenplatte 1 in
Die verzahnten und miteinander verklebten Bodenplatten werden auf höhenverstellbaren Stützen über einem Rohfußboden aufgestellt, wobei jeweils an den vier aneinander liegenden Ecken benachbarter Bodenplatten eine Stütze vorgesehen wird, die eine entsprechende Auflagefläche für die vier Ecken der benachbarten Bodenplatten aufweist. Vorzugsweise wird die Auflagefläche der Stützen so ausgelegt, dass die Bodenplatten auf der Auflagefläche aufgeklebt werden können.The toothed and glued together floor panels are placed on height adjustable supports on a bare floor, wherein in each case at the four adjacent corners of adjacent floor panels a support is provided which has a corresponding bearing surface for the four corners of the adjacent floor panels. Preferably, the support surface of the supports is designed so that the bottom plates can be glued to the support surface.
Die beschriebene Verzahnung von benachbarten Platten kann auch bei anderen Verkleidungsplatten vorgesehen werden, sie ist nicht auf Bodenplatten beschränkt.The described gearing of adjacent plates can also be provided in other cladding panels, it is not limited to floor slabs.
Es können auch zwei Führungszähne an der Stirnseite einer Platte vorgesehen werden, je nach Ausgestaltung der Zahnbreite und Plattendicke.It can also be provided two guide teeth on the front side of a plate, depending on the configuration of the tooth width and plate thickness.
Beim Zusammensetzen der Platten erleichtert der vordere Abschnitt des Führungszahns mit größerem Flankenwinkel den Eingriff der Verzahnung ineinander, während der innen liegende Flankenabschnitt 1.3a mit verringertem Neigungswinkel eine Zentrierung des Eingriffs ergibt. Durch die abgesetzte Ausgestaltung des Flankenwinkels am Führungszahn 1.3 ergibt sich somit ein leichteres Zusammensetzen benachbarter Platten im Verhältnis zu einem Führungszahn 1.3, der über die gesamte Flankenhöhe einen verringerten Neigungswinkel aufweist.When assembling the plates, the leading portion of the larger flank angle guide tooth facilitates engagement of the teeth, while the reduced angle side flank portion 1.3a provides centering of the mesh. The offset configuration of the flank angle on the guide tooth 1.3 thus results in an easier assembly of adjacent plates in relation to a guide tooth 1.3, which has a reduced angle of inclination over the entire flank height.
Der Führungszahn 1.3 dient vor allem in der Klebephase zur optimalen Zentrierung der darunter und darüber liegenden Klebezapfen 1.1 und 1.2.
Der geringfügige Abstand von ca. 0,05 bis 0,1 mm zwischen Zahn- und Nutflanken wird vorzugsweise auch an dem äußeren Abschnitt 1.3b des Führungszahns 1.3 und dem Abschnitt 2.3b der Führungsnut 2.3 vorgesehen.The slight distance of approximately 0.05 to 0.1 mm between the tooth and groove flanks is preferably also provided on the outer section 1.3b of the guide tooth 1.3 and the section 2.3b of the guide groove 2.3.
Anstelle der dargestellten Trapezform der Zähne kann auch eine gerundete Zahnform vorgesehen werden, wobei vor allem die Ecken der Zähne abgerundet sein können.Instead of the illustrated trapezoidal shape of the teeth and a rounded tooth shape can be provided, in particular, the corners of the teeth can be rounded.
