Abstract

Each support section is formed as an adjustable steel foot (2), and a number of such feet support a bearer plate (3), on which the plaster layer (4) is located. The bearer plate is formed as a sheathing component and the plaster layer is applied by pouring. The plaster type can also be formed from dry plaster plates. An acoustic insulator (6) is arranged between the steel foot and the basic floor.

Description

Die Erfindung bezieht sich auf einen Hohlraumboden, der oberhalb eines Rohbodens angeordnet ist, mit Stützabschnitten, die auf dem Rohboden stehen, und einer Estrichlage, die von den Stützabschnitten im Abstand zum Rohboden gehaltert ist.The invention relates to a cavity floor, which is arranged above a bare floor, with support sections which stand on the bare floor, and a screed layer which is held by the support sections at a distance from the bare floor.

Bekannte derartige Hohlraumböden bestehen aus vergleichsweise starren Kunststoflormteilen. Die Kunststofformteile sind derart ausgestaltet, daß bei Verfüllung dieser Kunststofformteile unter Ausgestaltung von Hohlräumen zwischen den Stützabschnitten ein ebener Boden entsteht, der um bis zu ca. 18 cm oberhalb des Rohbodens angeordnet ist. Die Verfüllung der Kunststofformteile erfolgt mit Fließestrich; sie kann entweder vor Ort, d.h. am Aufbauort des Hohlraumbodens, oder im Herstellungswerk der Kunststofformteile erfolgen. Derartige Kunststofformteile werden am Einbauort endlos aneinandergebaut.Known cavity floors of this type consist of comparatively rigid plastic standard parts. The plastic moldings are designed in such a way that when these plastic moldings are filled, with the formation of cavities between the support sections, a flat floor is formed, which is arranged up to approximately 18 cm above the raw floor. The molded plastic parts are filled with liquid screed; it can either be on site, i.e. at the installation site of the cavity floor, or in the manufacturing plant of the molded plastic parts. Such molded plastic parts are endlessly assembled at the installation site.

Im Normalfall werden die derart aneinandergebauten Kunststofformteile mit einer unterschiedlich dicken Fließestrichschicht übergossen.In the normal case, the molded plastic parts assembled in this way are covered with a differently thick self-leveling screed layer.

Derartige Hohlramböden haben vergleichsweise lange Trocknungszeiten, woraus sich ergibt, daß eine weitere Bearbeitung des Hohlrambodens für einen vergleichsweise langen Zeitraum ohne besondere Maßnahmen nicht möglich ist. Dies hat sehr häufig insoweit besondere Nachteile, als jedwede weiteren Arbeiten im Bereich desjenigen Raums, in dem der Hohlraumboden verlegt wird, unterbrochen bzw. verzögert werden müssen. Aufgrund der unterschiedlichen Schichtdicke der Estrichschicht ergibt sich eine unterschiedliche Austrocknung des Hohlraumbodens, wobei darüber hinaus der entstehende Hohlraum aufgrund von Katakombenausbildung vergleichsweise gering ist. Des weiteren hat ein derartiger kohlraumboden eine vergleichsweise geringe Aufbauhöhe von max. ca. 18 cm.Such hollow ram floors have comparatively long drying times, which means that further processing of the hollow ram floor for a comparatively long period of time is not possible without special measures. This very often has particular disadvantages in that any further work in the area in which the cavity floor is installed must be interrupted or delayed. Due to the different layer thickness of the screed layer, the cavity floor dries out differently, and the resulting cavity is also comparatively small due to the formation of catacombs. Furthermore, such a cavity floor has a comparatively low installation height of max. approx. 18 cm.

Aufgrund der vergleichsweise starren Ausgestaltung der Kunststofformteile kann nicht gewährleistet werden, daß tatsächlich jeder Stützabschnitt mit seiner Unterseite in fester Anlage am Rohboden ist.Due to the comparatively rigid design of the plastic moldings, it cannot be guaranteed that each support section with its underside is actually in firm contact with the bare floor.

Der Erfindung liegt die Aufgabe zugrunde, einen Hohlraumboden zu schaffen, der bei geringerer Austrocknungszeit eine gleichmäßigere Austrocknung, einen größeren Hohlraum und eine verbesserte Schalldämmung bietet, wobei darüber hinaus eine exakte Nivellielrbarkeit gewährleistet sein soll. Des weiteren soll mit dem erfindungsgemäßen Hohlraumboden sichergestellt werden, daß sämtliche Stützabschnitte fest gegen den Rohboden anliegen.The invention has for its object to provide a cavity floor that offers a more even drying out, a larger cavity and improved sound insulation with a shorter drying time, and in addition an exact levelability is to be ensured. Furthermore, the cavity floor according to the invention is intended to ensure that all the support sections lie firmly against the raw floor.

Diese Aufgabe wird erfindungsgemaß dadurch gelöst, daß jeder Stützabschnitt als verstellbarer Stahlfuß ausgebildet ist und daß jeweils eine Vielzahl Stahlfüße eine Trägerplatte tragen, auf der die Estrichlage aufgebracht ist. Durch Verstellung der verstellbaren Stahlfüße kann gewährleistet sein, daß die Unterseite eines jeden Stahlfußes bis zum Rohboden reicht und fest an diesem anliegt. Hierdurch ergibt sich eine gleichmäßige Kraftübertragung zwischen dem Hohlraumboden und dem Rohboden. Des weiteren ist der erfindungsgemäße Hohlraumboden beträchtlich kostengünstiger herzustellen als die bis dahin bekannten Hohlraumböden. Da die Estrichlage aufgrund der Nivellierung der Trägerplatte überall eine nahezu gleiche Dicke aufweist, die im Vergleich zum Stand der Technik vergleichsweise gering ist, ergeben sich eine weitaus geringere Austrocknungszeit bei gleichmäßiger Austrocknung. Aufgrund des vergleichsweise geringen Raumbedarfs für die verstellbaren Stahlfüße steht durch den erfindungsgemäßen Hohlraumboden ein großer Hohlraum zur Verfügung. Mittels Einstellung der verstellbaren Stahlfüße ist eine exakte Nivellierung der Trägerplatte in dem gewünschten Niveau ohne weiteres möglich.This object is achieved according to the invention in that each support section is designed as an adjustable steel foot and that a plurality of steel feet each carry a carrier plate on which the screed layer is applied. By adjusting the adjustable steel feet it can be ensured that the underside of each steel foot extends to the unfinished floor and fits tightly against it. This results in a uniform power transmission between the cavity floor and the bare floor. Furthermore, the cavity floor according to the invention is considerably cheaper to manufacture than the previously known cavity floors. Since the screed layer has an almost identical thickness everywhere due to the leveling of the support plate, which is comparatively small in comparison with the prior art, this results in a much shorter drying time with uniform drying. Due to the comparatively small space requirement for the adjustable steel feet, a large cavity is available through the cavity floor according to the invention. By adjusting the adjustable steel feet, an exact leveling of the carrier plate in the desired level is easily possible.

Vorteilhaft ist die Trägerplatte als Schalungselement und die Estrichlage als Fließestrichlage ausgebildet, wobei auf der als Schalungselement fungierenden Trägerplatte in herkömmlicher Weise eine Schrenzlage zum Einsatz kommt.The support plate is advantageously designed as a formwork element and the screed layer as a liquid screed layer, a sloping position being used in a conventional manner on the support plate functioning as formwork element.

Alternativ kann die Estrichlage jedoch auch aus Trockenestrichplatten ausgebildet sein, die dann auf die nivellierte Trägerplatte aufgebracht werden.Alternatively, however, the screed layer can also be formed from dry screed plates, which are then applied to the leveled support plate.

Um die Schalldämmung möglichst vorteilhaft zu gestalten, ist es zweckmäßig, wenn zwischen dem Stahlfuß und dem Rohboden ein Schallentkopplungselement vorgesehen ist.In order to make the sound insulation as advantageous as possible, it is expedient if a sound decoupling element is provided between the steel base and the bare floor.

Die Installierung eines derartigen Hohlraumbodens erfolgt, indem die Trägerplatte mit der Oberseite nach unten angeordnet wird, die verstellbaren Stahlfüße mit ihrem Standteil nach oben in in der Trägerplatte ausgebildete Bohrungen eingebracht werden, die vier an den Ecken der Trägerplatte angeordneten Stahlfüße roh eingestellt werden, die Trägerplatte mit den Stahlfüßen umgedreht und am Einsatzort aufgestellt wird, die vier an den Ecken der Trägerplatte angeordneten Stahlfüße im gewünschten Niveau nivelliert werden, die weiteren Stahlfüße der Trägerplatte verstellt werden, bis ihre Standteile auf dem Rohboden aufstehen, die über die Oberseite der Trägerplatte vorstehenden Abschnitte der Siahlfüße zumindest teilweise entfernt werden und auf die Trägerplatte eine Estrichlage aufgebracht wird.Such a cavity floor is installed by arranging the support plate upside down, inserting the adjustable steel feet with their upward part into bores formed in the support plate, the four steel feet arranged at the corners of the support plate are roughly adjusted, the support plate is turned over with the steel feet and set up at the place of use, the four steel feet arranged at the corners of the support plate are leveled at the desired level, the other steel feet of the support plate are adjusted until their parts stand on the bare floor, the sections of the projecting above the top of the support plate Filter feet are at least partially removed and a screed layer is applied to the carrier plate.

Sofern Fließestrich verwendet wird, wird auf die Trägerplatte eine Schrenzlage und darauf eine Fließestrichlage aufgebracht.If self-leveling screed is used, a barrier layer is applied to the carrier plate and a leveling screed layer is applied to it.

Bei der Verwendung von Trockenestrich werden auf die Trägerplatte Trockenestrichplatten aufgebracht.When using dry screed be on the carrier plate Dry screed boards applied.

Im folgenden wird die Erfindung an Hand einer Ausführungsform unter Bezugnahme auf die Zeichnung näher erläutert.In the following the invention is explained in more detail using an embodiment with reference to the drawing.

Es zeigen:

Show it:
Figure 1
a section through a cavity floor according to the invention; and
Figure 2
a schematic diagram of a carrier plate of the cavity floor according to the invention.

Ein in Figur 1 dargestellter Hohlraumboden wird auf einem Rohboden 1 installiert.A cavity floor shown in FIG. 1 is installed on a bare floor 1.

Ein derartiger Hohlraumboden hat als wesentliche Bauelemente Stahlfüße 2, eine Trägerplatte 3 und eine Estrichlage 4.Such a cavity floor has steel feet 2, a carrier plate 3 and a screed layer 4 as essential components.

Jeder Stahlfuß 2 hat ein Standteil 5, das an seiner Unterseite ein Schallentkopplungselement 6 aufweist. Mittels des Schallentkopplungselements 6 wird eine Schalldämpfung zwischen dem Rohboden 1 und dem darauf befindlichen Hohlraumboden bewerkstelligt.Each steel base 2 has a stand part 5, which has a sound decoupling element 6 on its underside. The sound decoupling element 6 is used to dampen sound between the raw floor 1 and the hollow floor located thereon.

Der Stahlfuß 2 ist hinsichtlich seiner Höhe einstellbar, z.B. mittels Gewindeanordnungen od.dgl. Durch Drehung des Stahlfußes, die von oben möglich ist, kann der Stahlfuß so eingestellt werden, bis sein Standteil 5 mit dem Schallentkopplungselement in fester Anlage am Rohboden sind.The height of the steel base 2 is adjustable, for example by means of threaded arrangements or the like. By turning the steel base, which is possible from above, the steel base can be adjusted until its base part 5 with the sound decoupling element are in a fixed system on the bare floor.

Die Trägerplatte 3, wie sie in Figur 2 dargestellt ist, weist vierundzwanzig Bohrungen auf, die den Stahlfüßen 2 zugeordnet sind. Nach Aufstellung der Trägerplatte 3 werden die über die Oberseite der Trägerplatte 3 vorstehenden Enden der Stahlfüße 2, sofern erforderlich, eingekürzt bzw. beseitigt. Daraufhin wird auf die exakt nivellierte Trägerplatte 3 eine Schrenzlage 7 aufgebracht. Nach Aufbringung der Schrenzlage 7 wird auf die Trägerplatte 3 bzw. die Schrenzlage 7 eine Estrichlage 4 in Form von Fließestrich aufgebracht. Die Fließestrichlage 4 hat aufgrund der genauen Nivellierung der Trägerplatte 3 überall die gleiche Schichtdicke, vorzugsweise ca. 3 cm, so daß sie überall gleichzeitig und darüber hinaus in vergleichsweise kurzer Zeit austrocknet.The carrier plate 3, as shown in FIG. 2, has twenty-four bores which are assigned to the steel feet 2. After the support plate 3 has been set up, the ends of the steel feet 2 projecting above the top of the support plate 3 are shortened or eliminated, if necessary. Then a Schrenzlage 7 is applied to the precisely leveled support plate 3. After application of the screed layer 7, a screed layer 4 in the form of liquid screed is applied to the carrier plate 3 or the screed layer 7. Due to the exact leveling of the carrier plate 3, the leveling screed layer 4 has the same layer thickness everywhere, preferably about 3 cm, so that it dries out everywhere simultaneously and moreover in a comparatively short time.

Die die Stützabschnitte des erfindungsgemäßen Hohlraumbodens bildenden Stahlfüße 2 nehmen vergleichsweise wenig Raum ein, so daß zwischen der Tragfläche des Hohlraumbodens und dem Rohboden 1 ein großes Hohlraumangebot für Leitungen etc. zur Verfügung steht.The steel feet 2 forming the supporting sections of the cavity floor according to the invention take up comparatively little space, so that a large amount of cavities for lines etc. is available between the supporting surface of the cavity floor and the unfinished floor 1.

Zur Installation des vorstehend beschriebenen Hohlraumbodens wird die Trägerplatte 3 mit ihrer Oberseite nach unten angeordnet. Daraufhin werden in die in der Trägerplatte 3 ausgebildeten Bohrungen die verstellbaren Stahlfüße 2 mit ihrem Standteil 5 nach oben angeordnet. Die vier an den Ecken der Trägerplatte 3 angeordneten Stahlfüße 2 werden roh eingestellt, d.h. sie werden hinsichtlich ihrer Länge so eingestellt, daß ihre Länge etwa dem gewünschten Abstand zwischen dem Rohboden 1 und der Unterseite der Trägerplatte 3 entspricht. Daraufhin wird die Trägerplatte 3 mit den Stahlfüßen 2 umgedreht und am Einsatzort aufgestellt. Zur Nivellierung der Trägerplatte 3 in der gewünschten Höhe werden die vier an den Ecken der Trägerplatte 3 angeordneten Stahlfüße mittels Nivellierschlauch oder Nivellierläser dem gewünschten Niveau nivelliert Daraufhin werden die anderen zwanzig Stahlfüße 2 der Trägerplatte 3 hinsichtlich ihrer Länge so eingestellt, daß sie mit ihrem Standteil 5 bzw. ihrem Schallentkopplungselement 6 in feste Anlage gegen den Rohboden 1 geraten. Sofern nach diesem Einstellvorgang der Stahlfüße 2 deren obere Enden in unerwünschtem Ausmaß über die Oberseite der Trägerplatte 3 hinausragen, werden diese überstehenden Abschnitte zumindest teilweise entfernt. Daraufhin wird auf die Trägerplatte eine Schrenzlage 7 aufgebracht, wonach auf diese Schrenzlage 7 Fließestrich aufgeschichtet wird.To install the cavity floor described above, the carrier plate 3 is arranged with its top down. Thereupon, the adjustable steel feet 2 are arranged with their stand part 5 upwards in the bores formed in the carrier plate 3. The four steel feet 2 arranged at the corners of the carrier plate 3 are set raw, ie they are adjusted with respect to their length so that their length corresponds approximately to the desired distance between the raw floor 1 and the underside of the carrier plate 3. The support plate 3 with the steel feet 2 is then turned over and set up at the place of use. To level the support plate 3 at the desired height, the four steel feet arranged at the corners of the support plate 3 are leveled to the desired level by means of a leveling hose or leveling glasses. The other twenty steel feet 2 of the support plate 3 are then adjusted in terms of their length so that they stand 5 or their sound decoupling element 6 come into firm contact against the raw floor 1. If, after this adjustment process, the steel feet 2 have their upper ends projecting beyond the upper side of the carrier plate 3 to an undesirable extent, these protruding sections are at least partially removed. Then a leveling layer 7 is applied to the carrier plate, after which 7 leveling screed is layered on this leveling layer.

Statt Fließestrich ist auch die Verwendung von Trockenestrichplatten möglich, da eine exakte Nivellierung des Hohlraumbodens aufgrund der exakten Nivellierung der Trägerplatte bzw der Trägerplatten 3 bereits erfolgt ist.Instead of self-leveling screed, the use of dry screed plates is also possible, since an exact leveling of the cavity floor has already taken place due to the exact leveling of the carrier plate or the carrier plates 3.
