Description

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Estrich-Hohlbodens, bei dem auf einem Rohboden mindestens ein mit Füßen versehenes Schalungselement verlegt wird, auf das anschließend eine Estrichmasse aufgebracht wird.The present invention relates to a method for producing a screed hollow floor, in which at least one formwork element provided with feet is laid on a raw floor, to which a screed mass is subsequently applied.

Hohlbodenkonstruktionen dienen zur bodenseitigen Installation von Kabeln, Rohren, und dgl.Raised floor constructions are used for installing cables, pipes, and the like on the floor.

Für die meisten Hohlbodenkonstruktionen muß zunächst ein ebener Unterboden hergestellt werden, auf dem das Schalungselement aufgebracht wird, damit alle Füße des Schalungselementes auf dem Unterboden aufstehen.For most hollow floor constructions, a flat sub-floor must first be produced, on which the formwork element is applied, so that all feet of the formwork element stand on the sub-floor.

Aus der EP-OS 0 133 556 ist es bekannt, für eine Hohlbodenkonstruktion ein Schalungselement zu verwenden, das eine Trägerplatte aufweist, die mit Ausnehmungen versehen ist, in welche die Füße formschlüssig eingreifen. Die Trägerplatte weist Nuten auf, damit sich die Schalungselemente besser der Boden anpassen. Der Hohlboden wird dadurch fertiggestellt, daß auf die Schalungselemente ein Fließestrich aufgegeben wird, so daß die Schalungselemente als verlorene Schalung wirken.From EP-OS 0 133 556 it is known to use a formwork element for a hollow floor construction which has a carrier plate which is provided with recesses in which the feet engage in a form-fitting manner. The carrier plate has grooves so that the formwork elements adapt better to the floor. The hollow floor is completed in that a leveling screed is applied to the formwork elements so that the formwork elements act as lost formwork.

Trotz der vorgesehenen Nuten kann es bei besonders unebenen Böden vorkommen, daß einige Füße den Unterboden nicht berühren. Auch der ausgebrachte Fließestrich ist nicht in der Lage, die Trägerplatte so weit durchzudrücken, daß die Füße an allen Stellen der Trägerplatte den Boden berühren. Der neu eingezogene Boden liegt an mehreren Stellen über weite Flächen hohl und ist an solchen Stellen dementsprechend weniger belastbar. In noch erheblich größerem Umfang tritt dieser Nachteil etwa bei Verwendung eines Fußbodenelements auf, wie es aus der DE-PS 29 30 426 bekannt ist, und das eine Platte mit einer Vielzahl von Füßen zeigt, ohne daß jedoch entsprechende Nuten vorgesehen sind.In spite of the grooves provided, it can happen with particularly uneven floors that some feet do not touch the sub-floor. Even the spread liquid screed is not able to push through the carrier plate so far that the feet in all places Touch the support plate to the floor. The newly drawn-in floor is hollow over large areas in several places and is therefore less resilient in such places. To a considerably greater extent, this disadvantage occurs, for example, when using a floor element, as is known from DE-PS 29 30 426, and which shows a plate with a large number of feet, but without corresponding grooves being provided.

Darüber hinaus ist aus der DE-PS 31 03 632 ein Verfahren zur Herstellung eines Hohlbodens bekannt, bei welchem eine Noppenfolie auf den Rohboden aufgebracht wird, die dann mit einem Fließestrich abgedeckt wird. Die Noppenfolie steht mit den die Füße bildenden Noppen auf dem Unterboden auf. Nachteilig an dem bekannten Verfahren ist, daß die Noppenfolie nicht begehbar ist, so daß besondere Hilfskonstruktionen erforderlich sind, um den Estrich aufzubringen. Wegen der großen Estrichdicke benötigt diese darüber hinaus eine lange Austrockungszeit.In addition, from DE-PS 31 03 632 a method for producing a hollow floor is known, in which a knobbed film is applied to the raw floor, which is then covered with a liquid screed. The knobbed film stands on the underbody with the knobs that form the feet. A disadvantage of the known method is that the knobbed film cannot be walked on, so that special auxiliary structures are required in order to apply the screed. Because of the large screed thickness, this also requires a long drying time.

Aus der FR-A-2 036 518 sind Platten bekannt, die zur Herstellung von Fußböden, insbesondere provisorischer, zeitweilig genützter Fußöden, im Verband verlegt werden können. Die Platten sind mit kurzen, entsprechend den Eckpunkten eines Dreiecks angeordneten Füßen versehen, so daß zwischen den Platten und dem Unterboden ein Zwischenraum, zum Beispiel für die Verlegung von Kabeln, verbleibt.From FR-A-2 036 518, slabs are known which can be installed in association in order to produce floors, in particular temporary, temporarily used floors. The plates are provided with short feet arranged according to the corner points of a triangle, so that a space remains between the plates and the sub-floor, for example for laying cables.

Aus der DE-U-6 912 292 ist ein Bausatz für die Verlegung von Hohlfußböden bekannt, der aus im wesentlichen dreieckigen Bodenplatten und Ständerelementen besteht, durch die die dreieckigen, im Verband verlegbaren Bodenplatten jeweils an ihren Ecken gegen den Boden abgestützt werden.From DE-U-6 912 292 a kit for the laying of hollow floors is known, which consists of essentially triangular floor panels and stand elements, by means of which the triangular floor panels which can be laid in association are supported at their corners against the floor.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs erwähnten Art für die Herstellung eines Estrichhohlbodens vorzuschlagen, durch das sich Estrichhohlböden mit verbesserter Tragfähigkeit und Haltbarkeit herstellen lassen.The invention has for its object to propose a method of the type mentioned for the manufacture of a screed hollow floor, by means of which screed hollow floors can be produced with improved load-bearing capacity and durability.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine Vielzahl von mit jeweils drei Füßen in dreiecksartiger Anordnung versehenes Schalungselementes im Verband verlegt wird, die anschließend mit einer Folie abgedeckt werden, auf die dann die Estrichmasse aufgebracht wird.This object is achieved in that a plurality of formwork elements, each provided with three feet in a triangular arrangement, are laid in the association, which are then covered with a film, to which the screed mass is then applied.

Diese Lösung ist verblüffend einfach. Der Estrichhohlböden wird aus einer Vielzahl solcher Schalungselemente zusammengesetzt, die aufgrund ihrer Ausbildung mit jeweils drei Füßen stets mit allen Füßen auf dem Unterboden aufstehen. Dennoch können die Schalungselemente aus einem starren und steifen Naterial bestehen, so daß sich die Bereiche zwischen den Füßen nicht eindrücken können. Ein mit den erfindungsgemäßen Schalungselementen aufgebauter Hohlboden weist daher eine hohe Tragfähigkeit auf, da der gesamte Hohlboden auch bei sehr unebenen Rohböden von allen, an der Unterseite der Schalungsplatte angeordneten Füßen getragen wird. Auf der anderen Seite ist es möglich, daß auch nachträglich Kabel oder Rohre bodenseitig installiert werden können.This solution is amazingly simple. The screed hollow floors are made up of a large number of such formwork elements composed, which due to their training with three feet always stand with all feet on the sub-floor. Nevertheless, the formwork elements can consist of a rigid and rigid material, so that the areas between the feet cannot be indented. A hollow floor constructed with the formwork elements according to the invention therefore has a high load-bearing capacity, since the entire hollow floor is supported by all the feet arranged on the underside of the formwork panel even in the case of very uneven raw floors. On the other hand, it is possible that cables or pipes can also be installed on the floor later.

Es wird bevorzugt, daß die Füße voneinander etwa den gleichen Abstand aufweisen. So wird für den gesamten Hohlboden eine gleichmäßige Flächenpresssung erreicht; jeder der Füße der Schalungselemente trägt im wesentlichen die gleiche Last.It is preferred that the feet be approximately the same distance from each other. A uniform surface pressure is achieved for the entire hollow floor; each of the feet of the formwork elements carries essentially the same load.

Gemäß einer bevorzugten Ausführungsform bilden die Füße die Eckpunkte eines gedachten gleichschenkligen Dreiecks. Die Schalungsplatten der Schalungselemente können nur beliebige Formen aufweisen, die es gestatten, daß die Schalungselemente ineinander verschachtelt, also im Verband, gelegt werden können.According to a preferred embodiment, the feet form the corner points of an imaginary isosceles triangle. The formwork panels of the formwork elements can have any shape that allows the formwork elements to be nested one inside the other, that is to say they can be put together.

Obwohl auch andere Formen denkbar sind, wird gemäß einem bevorzugten Ausführungsbeispiel ein Schalungselement verwendet, dessen Schalungsplatte in der Draufsicht eine L-Form aufweist. Ein solche L-Form gestattet es, auf einfache Weise einen Plattenverbund zu verlegen.Although other shapes are also conceivable, a formwork element is used according to a preferred embodiment, the formwork plate of which has an L-shape in plan view. Such an L-shape allows a panel assembly to be laid in a simple manner.

Für eine besonders gleichmäßige Lastverteilung der Hohlbodenkonstruktion ist es vorteilhaft, wenn die Schalungsplatte in drei etwa quadratische Abschnitte aufgeteilt ist, unter denen jeweils ein Fuß angeordnet ist.For a particularly uniform load distribution of the hollow floor construction, it is advantageous if the formwork panel is divided into three approximately square sections is divided, under each of which a foot is arranged.

Besonders bevorzugt ist die Schalungsplatte einstückig mit den Füßen ausgebildet. Das Schalungselement kann so z.B. aus einem anorganischen Gips oder Anhydrid oder einem Zement oder einer Mischung daraus hergestellt sein.The formwork panel is particularly preferably formed in one piece with the feet. The formwork element can e.g. be made from an inorganic gypsum or anhydride or a cement or a mixture thereof.

Zur Gewichtseinsparung, zur Verringerung der Transport-und Verlegungskosten sowie zur Vereinfachung des Fertigungsverfahrens ist es zweckmäßig, wenn die Füße eine zur Schalungsplatte hin offene Becherform aufweisen. Außerdem wird sich ein nachher aufgebrachter Fließestrich besonders gut mit den Schalungselementen verbinden. Außerdem könnte zuvor in jeder beliebiger Becherausnehmung etwa eine Elektrodose installiert werden.In order to save weight, to reduce transport and laying costs and to simplify the manufacturing process, it is expedient if the feet have a cup shape which is open towards the formwork panel. In addition, a floating screed applied afterwards will bond particularly well to the formwork elements. In addition, an electrical socket could be installed in any cup recess beforehand.

Gemäß einem anderen bevorzugten Ausführungs beispiel für das erfindungsgemäße Verfahren weist die Schalungsplatte eine Dreiecksform auf. Solche Schalungselemente eignen sich insbesondere für kleinere Räume.According to another preferred embodiment example for the method according to the invention, the formwork panel has a triangular shape. Such formwork elements are particularly suitable for smaller rooms.

Weiterhin werden bevorzugt Schalungselemente verwendet, deren Schalungsplatte wabenförmig ausgebildet ist. Eine soche Wabenform, die sechseckig, achteckig od. dgl. sein kann, ermöglicht ein einfaches Aneinanderlegen der Schalungselemente, ohne daß durchgehende gerade Fugen entstehen können.Furthermore, formwork elements are preferably used, the formwork plate of which is honeycomb-shaped. Such a honeycomb shape, which can be hexagonal, octagonal or the like, enables the formwork elements to be simply placed against one another without continuous straight joints being formed.

Gemäß einer bevorzugten Ausführungsform beträgt der Abstand der Füße voneinander etwa 20 cm. So läßt sich bei geringer Aufwand bei der Herstellung der Schalungselemente eine gute Anpassung der Schalungselemente an den Untergrund und eine hohe Tragfähigkeit erreichen.According to a preferred embodiment, the distance between the feet is approximately 20 cm. This allows a good adjustment of the formwork elements with little effort Formwork elements to the sub-surface and achieve a high load-bearing capacity.

Bevorzugt wird auch, wenn die Kantenlänge der Schalungsplatte etwa das zweifache des Fußabstandes beträgt. Auf diese weise wird erreicht, daß die Abstände der Füße auch beim verlegten Hohlboden insgesamt zueinander etwa gleich sind.It is also preferred if the edge length of the formwork panel is approximately twice the base distance. In this way it is achieved that the distances between the feet are approximately the same to each other even when the hollow floor is installed.

Je nach Art der unterhalb der Hohlbodenkonstruktion vorzusehenden Installation beträgt die Höhe der Füße etwa zwischen 5 und 20 cm.Depending on the type of installation to be provided below the hollow floor construction, the height of the feet is approximately between 5 and 20 cm.

Nach dem anschließenden Ausbreiten einer Folie, die bei eventuell vorhandenen Fugen zwischen den Schalungsplatten der Schalungselemente ein Durchfallen von Estrichmasse verhindert, kann in herkömmlicher Weise beispielsweise ein Fließestrich aufgebracht werden. Nach Aufbringen des Fließestriches ergibt sich eine mehr oder weniger starke Verbindung der einzelnen Schalungselemente miteinander und der Schalungselemente mit dem Estrich.After the subsequent one Spreading out a film that prevents any screed from falling through in the case of joints between the formwork panels of the formwork elements, for example a liquid screed can be applied in a conventional manner. After the liquid screed has been applied, there is a more or less strong connection between the individual formwork elements and the formwork elements with the screed.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand einer Zeichnung näher beschrieben. Es zeigen:

Die Fig. 1 zeigt in einer Draufsicht ein Schalungselement 1 für die Verlegung von Hohlböden 2.1 shows a top view of a formwork element 1 for laying hollow floors 2.

Das in Fig. 1 dargestellte Schalungselement 1 weist eine im wesentlichen ebene Schalungsplatte 3 und auf deren Unterseite angeordnete Füße 4 auf.The formwork element 1 shown in FIG. 1 has an essentially flat formwork panel 3 and feet 4 arranged on its underside.

Wie aus Fig. 1 deutlich zu erkennen ist, sind auf der Unterseite des Schalungselementes 1 in einer dreieckartigen Anordnung 3 Füße 4 angebracht.As can be clearly seen from Fig. 1, 3 feet 4 are attached to the underside of the formwork element 1 in a triangular arrangement.

Die Füße 4 weisen voneinander etwa den gleichen Abstand a auf. Genaugenommen bilden die Füße 4 bei dem in Fig. 1 dargestellten Ausführungsbeispiel die Eckpunkte eines gedachten gleichschenkligen Dreiecks. Das Schalungselement 1 bzw. besser dessen Schalungsplatte 3 weist in der Draufsicht eine L-Form auf.The feet 4 are at approximately the same distance a from one another. Strictly speaking, the feet 4 in the embodiment shown in FIG. 1 form the corner points of an imaginary isosceles triangle. The formwork element 1 or better its formwork panel 3 has an L-shape in plan view.

Die Schalungsplatte ist in drei etwa quadratische Abschnitte 5 aufgeteilt, unter denen jeweils ein Fuß 4 angeordnet ist. Die quadratischen Abschnitte 5 sind einstückig miteinander verbunden, so daß jeweils drei quadratische Abschnitte 5 ein L-förmiges Schalungselement 1 bilden. Die quadratischen Abschnitte 5 können an ihren aneinander angrenzenden Kanten Schwächungslinien aufweisen, so daß aus einem L-förmigen Schalungselement ein quadratischer Abschnitt 5 abgebrochen werden kann, der als Paßstück in Randbereichen bei der Verlegung eines Hohlbodens verwendet werden kann.The formwork panel is divided into three approximately square sections 5, under each of which a foot 4 is arranged. The square sections 5 are integrally connected to one another, so that three square sections 5 each form an L-shaped formwork element 1. The square sections 5 can have lines of weakness at their mutually adjacent edges, so that a square section 5 can be broken off from an L-shaped formwork element, which can be used as a fitting in edge areas when laying a hollow floor.

Wie insbesondere aus Fig. 2 ersichtlich ist, ist die Schalungsplatte 3 einstückig mit den Füßen 4 ausgebildet.As can be seen in particular from FIG. 2, the formwork panel 3 is formed in one piece with the feet 4.

Obwohl es auch denkbar ist, daß die Füße massiv ausgebildet sind, sind bei dem hier dargestellten Ausführungsbeispiel die Füße 4 als zur Schalungsplatte 3 hin offene Becher ausgebildet. Die Schalungsplatte 3 könnte an der Becheroberseite auch durchgehen, so daß die Füße 4 als geschlossene Hohlkörper ausgebildet wären.Although it is also conceivable that the feet are solid, in the embodiment shown here the feet 4 are designed as cups open towards the formwork panel 3. The formwork panel 3 could also go through on the top of the cup, so that the feet 4 would be formed as a closed hollow body.

Der Abstand a der Füße 4 voneinander beträgt etwa 20 cm. Die Kantenlänge b der Schalungsplatte 3 beträgt etwa das zweifache des Fußabstandes a. Die Höhe h der Füße 4 liegt je nach Einbaubedürfnissen etwa zwischen 5 und 20 cm.The distance a between the feet 4 is approximately 20 cm. The edge length b of the formwork panel 3 is approximately twice the base distance a. The height h of the feet 4 is approximately between 5 and 20 cm, depending on the installation requirements.

In den Fig. 4 und 5 sind weitere Ausführungsbeispiele für ein bei dem erfindungsgemäßen Verfahren verwendbares Schalungselemente dargestellt. Der Aufbau dieser Schalungselemente ist im Prinzip gleich zu dem Schalungselement gemäß Ausführungsbeispiel nach Fig. 1. Es werden daher im folgenden nur die Unterschiede beschrieben. Für gleichwirkende Bauteile werden diesselben Bezugszeichen verwandt.4 and 5 show further exemplary embodiments of a formwork element which can be used in the method according to the invention. The structure of these formwork elements is in principle the same as that of the formwork element according to the exemplary embodiment according to FIG. 1. Only the differences are therefore described below. The same reference numerals are used for components with the same effect.

In Fig. 4 ist ein in der Draufsicht dreieckförmiges Schalungselement 1 dargestellt, bei dem die Füße 4 ebenfalls in etwa dreieckartiger Anordnung derart ausgebildet sind, daß sie die Eckpunkte eines gleichschenkligen Dreiecks bilden. Der Fußabstand a liegt hier in etwa ebenso, wie bei dem in Fig. 1 gezeigten Ausführungsbeispiel, ebenso die Kantenlänge b und die Höhe h der Füße 4.FIG. 4 shows a formwork element 1 which is triangular in plan view, in which the feet 4 are also formed in an approximately triangular arrangement such that they form the corner points of an isosceles triangle. The foot distance a is approximately the same as in the embodiment shown in FIG. 1, as is the edge length b and the height h of the feet 4.

Die Fig. 5 zeigt ein in der Draufsicht wabenförmiges Schalungselement 1, genauer ein Schalungselement mit einer Schalungsplatte in Form eines regelmäßigen Sechsecks. Die Füße 4 sind bei diesem Schalungselement 1 so angeordnet, daß sie die Eckpunkte eines gleichseitigen, gedachten Dreiecks bilden.5 shows a formwork element 1 which is honeycomb-shaped in plan view, more precisely a formwork element with a formwork plate in the form of a regular hexagon. The feet 4 are arranged in this formwork element 1 so that they form the corner points of an equilateral, imaginary triangle.

Die Kantenlänge b liegt bei dem in Fig. 5 gezeigten Ausführungsbeispiel etwa in der Größenordnung des Fußabstandes a.In the exemplary embodiment shown in FIG. 5, the edge length b is approximately in the order of the foot spacing a.

Im folgenden wird die Wirkungsweise der bei dem erfindungsgemäßen Verfahren verwendbarem Schalungselemente 1 näher erläutert.The mode of operation of the formwork elements 1 which can be used in the method according to the invention is explained in more detail below.

In Fig. 3 ist ein Verlegebeispiel der Schalungselemente 1 gemäß Ausführungsbeispiel nach Fig. 1 dargestellt.3 shows a laying example of the formwork elements 1 according to the embodiment of FIG. 1.

Die Schalungselemente 1 werden mit ihren Füßen 4 auf einen Rohboden 6 gestellt und im Verband verlegt. Jedes Schalungselement 1 steht mit allen seinen drei Füßen 4 auf dem Rohboden 6 auf, so daß die Schalungsplatte 3 parallel zu der Oberfläche des Rohbodens 6 an dieser Stelle ist. Das bedeutet, daß je nach Beschaffenheit des Rohbodens 6 die Oberseite des durch die Schalungsplatte gebildeten Hohlbodens 2 uneben sein kann. Die Schalungselemente können in verschiedenen Verbänden verlegt werden; die Fig. 3 zeigt nur ein Beispiel einer Verlegemöglichkeit.The formwork elements 1 are placed with their feet 4 on an unfinished floor 6 and laid in the association. Each formwork element 1 stands with all its three feet 4 on the raw floor 6, so that the formwork panel 3 is parallel to the surface of the raw floor 6 at this point. This means that depending on the nature of the raw floor 6, the top of the hollow floor 2 formed by the formwork panel may be uneven. The formwork elements can be installed in different associations; 3 shows only one example of a laying option.

Nachdem die Schalungselemente auf dem Rohboden ausgelegt sind, kann eine hier nicht näher dargestellte Folie, z.B. eine Polyethylenfolie, über die Schalungsplatte 3 der Schalungselemente 1 ausgelegt werden. Auf diese Folie, die etwaige Fugen zwischen den Schalungselementen 1 abdeckt, wird dann ein Fließestrich oder eine Trockenschüttung aufgebracht, die etwaige Unebenheiten aufgrund eines unebenen Rohbodens ausgleicht.After the formwork elements have been laid out on the bare floor, a film, not shown here, e.g. a polyethylene film over which the formwork panel 3 of the formwork elements 1 are laid out. A floating screed or a dry fill is then applied to this film, which covers any joints between the formwork elements 1, which compensates for any unevenness due to an uneven raw floor.

Bei dem in Fig. 4 dargestellen Schalungselement 1 ist eine Verlegemöglichkeit mit strichpunktierter Linie augedeutet.In the formwork element 1 shown in FIG. 4, a laying option with a dash-dotted line is indicated.

Ebenso ist mit strichpunktierter Linie auch eine Verlegungsmöglichkeit für die Schalungselemente 1 nach dem Ausführungsbeispiel gemäß Fig. 5 angedeutet.Likewise, the possibility of laying the formwork elements 1 according to the exemplary embodiment according to FIG. 5 is indicated with a dash-dotted line.

Die Vorgehensweise zur Fertigstellung des Hohlbodens ist bei den in Fig. 4 und 5 gezeigten Ausführungsbeispielen dieselbe, wie bei dem zuvor beschriebenen Ausführungsbeispiel nach Fig. 1.The procedure for completing the hollow floor is the same in the exemplary embodiments shown in FIGS. 4 and 5 as in the previously described exemplary embodiment according to FIG. 1.

Bei einem fertiggelegten Hohlboden aus für ein bei dem erfindungsgemäßen Verfahren anwendbaren Schalungselementen ist stets gewährleistet, daß alle Füße 4 des gesamten Hohlbodens 2 auf dem Rohboden 6 aufliegen, wodurch der Hohlboden 2 eine hohe Tragfähigkeit aufweist, unabhängig von dem Geschick des Bodenverlegers.In the case of a finished hollow floor made of formwork elements which can be used in the method according to the invention, it is always ensured that all feet 4 of the entire hollow floor 2 rest on the unfinished floor 6, as a result of which the hollow floor 2 has a high load-bearing capacity, regardless of the skill of the flooring installer.

Als Material für die Schalungselemente eignet sich anorganischer Gips oder Anhydrid oder Zement. Es ist auch möglich, eine Mischung aus diesen Materialien zu verwenden. Die Füße müssen nicht, wie bei den gezeigten Ausführungsbeispielen, einstückig mit der Schalungsplatte ausgebildet sein, es ist auch denkbar, daß angeformte Füße Verwendung finden können.Inorganic gypsum or anhydride or cement is suitable as the material for the formwork elements. It is also possible to use a mixture of these materials. The feet do not have to be formed in one piece with the formwork panel, as in the exemplary embodiments shown, it is also conceivable that molded feet can be used.
