Description

Die Erfindung bezieht sich auf eine stufenlos verstellbare Stütze für einen Doppelboden mit den Merkmalen des Patentanspruches 1.The invention relates to a continuously adjustable support for a raised floor with the features of claim 1.

Üblicherweise müssen in Räumen von Büros, Labors oder Industrieanlagen Energieanschlüsse, Telefonleitungen sowie Klima-Installationen und gegebenenfalls noch Kabel für Datenverarbeitungsanlagen im Boden verlegt werden. Diesen Anforderungen werden die bisher üblichen Kabelkanäle im allgemeinen nicht gerecht, so daß sogenannte « Doppelböden » entwickelt worden sind, d. h. auf der tragenden Unterdecke wird in einem vorgegebenen Abstand ein Oberboden verlegt, so daß der dadurch entstehende Zwischenraum für die erwähnten Installationen genutzt werden kann.Usually, in the rooms of offices, laboratories or industrial plants, energy connections, telephone lines as well as air conditioning installations and possibly cables for data processing systems have to be laid in the floor. The previously customary cable ducts generally do not meet these requirements, so that so-called "double floors" have been developed, i. H. an upper floor is laid on the load-bearing false ceiling at a predetermined distance, so that the resulting space can be used for the installations mentioned.

Der Abstand zwischen den beiden Bodenflächen wird insbesondere bei brandschutztechnischen Anforderungen durch stufenlos verstellbare Stahlstützen eingestellt, die aus einer teleskopisch ineinander verschiebbaren und im Gewindeeingriff miteinander stehenden Rohr/Gewindebolzen-Einheit besteht. Durch eine Verdrehung vom Gewindebolzen lassen sich diese in dem Rohr einoder ausfahren, wodurch der entsprechende Abstand eingestellt werden kann.The distance between the two floor surfaces is adjusted, in particular in the case of fire protection requirements, by means of steplessly adjustable steel supports which consist of a tube / threaded bolt unit which can be telescopically pushed into one another and is in threaded engagement with one another. By rotating the threaded bolt, these can be extended or retracted in the tube, which means that the appropriate distance can be set.

Nachteilig bei dieser Konstruktion ist jedoch, daß mindestens ein Teil der Stützen verdreht werden muß, so daß sich hierdurch eine entsprechende Drehbewegung zwischen der Stützplatte und der entsprechenden Bodenfläche erigbt. Damit is*also ein Verdrehen bei aufgelegten Bodenplatten nicht möglich. Außerdem ist die exakte Verstellung dieser Stützen um nur geringe Strekken im allgemeinen mit Schwierigkeiten verbunden.A disadvantage of this construction, however, is that at least some of the supports have to be rotated, so that this results in a corresponding rotational movement between the support plate and the corresponding floor surface. Thus is * therefore possible twisting when placed floor panels not. In addition, the exact adjustment of these supports by only small distances is generally associated with difficulties.

Durch die FR-A-2 317 445 ist eine stufenlos verstellbare Stütze für einen Doppelboden bekannt geworden, die gemäß dem Gattungsbegriff des Patentanspruches 1 aus einem stationären Unterteil mit einer Fußplatte und einem Fußrohr sowie einem vertikal verstellbaren Oberteil mit einer Stützplatte und einem teleskopisch über eine Gewindeverbindung innerhalb des Fußrohres verstellbaren Stützrohr besteht. Dabei ist das Stützrohr mit einem Außengewinde versehen und unverdrehbar im Fußrohr geführt. Das obere Ende des Fußrohres trägt einen verdrehbaren Stellring, dessen Innengewinde in Eingriff mit dem Außengewinde des Stützrohres ist.From FR-A-2 317 445 an infinitely adjustable support for a raised floor has become known which, according to the preamble of claim 1, consists of a stationary lower part with a footplate and a foot tube and a vertically adjustable upper part with a support plate and a telescopic one There is a threaded connection within the adjustable support tube. The support tube is provided with an external thread and is non-rotatably guided in the base tube. The upper end of the foot tube carries a rotatable adjusting ring, the internal thread of which is in engagement with the external thread of the support tube.

Um eine relative Verdrehung zwischen Fußrohr und Stützrohr zu vermeiden, weist das Stützrohr eine Längsnut auf, über das es in nicht näher beschriebener Weise abhängig von der Stellung eines auf das Fußrohr aufgesetzten Kopfes unverdrehbar geführt ist.In order to avoid a relative rotation between the foot tube and the support tube, the support tube has a longitudinal groove, through which it is guided non-rotatably in a manner not described, depending on the position of a head placed on the foot tube.

Nachteilig bei der vorbekannten Ausführungsform ist, daß die Kräfte auf das Stützrohr so einseitig angreifen, wobei Verkantung und damit Ungleichmäßigkeiten bei der Führung in der Höhenverstellungen nicht zu vermeiden sind.A disadvantage of the known embodiment is that the forces act on the support tube on one side, whereby canting and thus irregularities in the guidance in the height adjustments cannot be avoided.

Aufgabe der Erfindung ist es eine stufenlos verstellbare Stütze für einen Doppelboden der genannten Gattung so weiter zu bilden, daß eine Verstellung in der Höhe ohne Verdrehung der Stützplatte klemmfrei und ohne zusätzliche Werkzeuge erreicht werden kann.The object of the invention is to provide a continuously adjustable support for a raised floor of the type mentioned so that an adjustment in height without rotation of the support plate can be achieved without jamming and without additional tools.

Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, das Stützrohr mit einem mehreckigen Querschnitt zu versehen und den oberen Bereich des Fußrohres auf eine der Außenkontur des Stützrohes entsprechende, mehreckige, Form zu pressen bzw. das obere Ende des Fußrohres durch eine ringförmige Kappe mit einer der Außenkontur des Stützrohres entsprechenden mehreckigen, Öffnung abzuschließen.To achieve this object, it is proposed according to the invention to provide the support tube with a polygonal cross-section and to press the upper region of the foot tube into a polygonal shape corresponding to the outer contour of the support tube or to press the upper end of the foot tube through an annular cap with one of the outer contour of the support tube corresponding polygonal to close the opening.

Zweckmäßige Ausgestaltungen der Erfindung sind in den Unteransprüchen genannt.Appropriate embodiments of the invention are mentioned in the subclaims.

Die mit der Erfindung erzielbaren Vorteile bestehen darin, daß sich Fußrohr und Stützrohr nicht mehr relativ zueinander verdrehen können, sondern daß nur noch ein Verstellring gedreht werden muß, der das Stützrohr nach oben unten verschiebt. Dadurch wird bei einer vertikalen Verschiebung des Stützrohres die Stützplatte zur Aufnahme der Fußbodenplatten nicht mehr um seine Achse gedreht, so daß damit auch eine exaktere Positionierung möglicht ist. Der Verstellring kann problemlos von Hand gedreht werden, so daß sich auf kleine Höhen Differenzen einstellen lassen, ohne daß die Benutzung eines zusätzlichen Werkzeuges erforderlich ist.The advantages that can be achieved with the invention are that the base tube and the support tube can no longer rotate relative to one another, but that only an adjustment ring has to be rotated, which moves the support tube up and down. As a result, when the support tube is displaced vertically, the support plate for receiving the floor plates is no longer rotated about its axis, so that more exact positioning is also possible. The adjustment ring can easily be turned by hand, so that differences can be set at small heights without the use of an additional tool.

Die zunächst in Fig. 1 dargestellte und allgemein mit dem Bezugszeichen 10 versehene Stütze weist ein zylindrisches Fußrohr 12 mit einer starr daran angesetzten Fußplatte 11 auf. Das obere Ende des zylindrischen Fußrohres 12 ist mit einer ringförmigen Kappe 13 versehen, die eine quadratische Öffnung 13a entsprechend Fig. 2 aufweist.The support shown initially in FIG. 1 and generally provided with the reference numeral 10 has a cylindrical foot tube 12 with a foot plate 11 rigidly attached to it. The upper end of the cylindrical foot tube 12 is provided with an annular cap 13 which is a quadra table opening 13a corresponding to FIG. 2.

Fußplatte 11, Fußrohr 12 und Kappe 13 bilden somit das stationäre Unterteil der Stütze 10.Base plate 11, base tube 12 and cap 13 thus form the stationary lower part of the support 10.

Das Oberteil der Stütze 10 wird durch ein Stützrohr 14 mit zum Beispiel quadratischer Au-Benkontur gebildet, an dessen oberen Ende die Stützplatte 16 angeschweißt ist. Das Außendurchmesser-Eckmaß des Stützrohres 14 ist etwas geringer als der Innendurchmesser der Öffnung 13a der Kappe 13 des Unterteils, so daß Stützrohr 14 in der Öffnung 13a und damit in dem Fußrohr 12 verschoben werden kann.The upper part of the support 10 is formed by a support tube 14 with, for example, a square Au-B contour, on the upper end of which the support plate 16 is welded. The outer diameter corner dimension of the support tube 14 is slightly smaller than the inner diameter of the opening 13a of the cap 13 of the lower part, so that the support tube 14 can be moved in the opening 13a and thus in the foot tube 12.

Das Stützrohr 14 ist mit einem Außengewinde 18 versehen, d. h. in die vier Ecken des quadratischen Stützrohres 14 ist ein Gewinde 18 eingeschnitten.The support tube 14 is provided with an external thread 18, i. H. a thread 18 is cut into the four corners of the square support tube 14.

Auf dieses Stützrohr 14 ist nunmehr ein Verstellring 20 - wie insbesondere aus Fig. 3 zu ersehen ist - aufgeschraubt, der auf der oberen Stirnfläche der Kappe 13 aufliegt und dessen Innenfläche mit einem Innengewinde versehen ist, das dem Au- βengewinde 18 Stützrohres 14 entspricht, d. h. das Stützrohr 14 und der Verstellring 20 stehen in Gewindeverbindung miteinander.An adjustment ring 20 is now screwed onto this support tube 14, as can be seen in particular from FIG. 3, which rests on the upper end face of the cap 13 and whose inner surface is provided with an internal thread which corresponds to the external thread 18 of the support tube 14, d. H. the support tube 14 and the adjusting ring 20 are in threaded connection with one another.

Die obere Stirnfläche der Kappe 13 ist mit einer radialen rippenförmigen Noppe 21 versehen, die als Drehsicherung dient und in formschlüssigen Eingriff mit einer der entsprechenden nutförmigen Aussparungen 22 kommt, die in gleichen Winkelabständen in der Unterseite des Verstellringes 20 eingelassen sind. Bei dem Ausführungsbeispiel nach Fig. 3 weist der Verstellring 20 beispeilsweise 8 Aussparungen 22 auf, so daß der Verstellring 20 durch Eingriff zwischen einer Aussparung 22 und der Noppe 21 in einer entsprechenden Winkellage in Bezug auf Stützrohr 14 und Fußrorh 12 angeordnet werden kann.The upper end face of the cap 13 is provided with a radial rib-shaped knob 21, which serves as a rotation lock and comes into positive engagement with one of the corresponding groove-shaped recesses 22, which are embedded at equal angular intervals in the underside of the adjusting ring 20. In the embodiment according to FIG. 3, the adjusting ring 20 has, for example, 8 recesses 22, so that the adjusting ring 20 can be arranged in a corresponding angular position with respect to the support tube 14 and the foot tube 12 by engagement between a recess 22 and the knob 21.

Die Stütze 10 wird in der aus Fig. 1 ersichtlichen Lage zwischen der tragenden Decke und den Doppelbodenplatten angeordnet, wobei die Fußplatte 11 fest auf dem Unterboden aufliegt und dort befestigt werden kann. Durch eine Drehbewegung des Verstellrings 20 wird das quadratische Stützrohr 14 ebenfalls ohne Verdrehung nach oben bzw. unten verschoben, so daß der gewünschte Abstand eingestellt werden kann. Nach Beendigung der Verstellung rastet die Noppe 21 in einer Aussparung 22 ein, so daß der Verstellring 20 in der entsprechenden Winkellage und damit das Stützorhr 14 in der entsprechenden Höhe fixiert sind.The support 10 is arranged in the position shown in FIG. 1 between the load-bearing ceiling and the raised floor panels, the base plate 11 resting firmly on the sub-floor and being able to be fastened there. By rotating the adjusting ring 20, the square support tube 14 is also moved up and down without rotation, so that the desired distance can be set. After the end of the adjustment, the knob 21 engages in a recess 22, so that the adjusting ring 20 is fixed in the corresponding angular position and thus the support tube 14 at the appropriate height.

In Fig. 4 ist eine weitere vorteilhafte Ausgestaltung einer derartigen Stütze 30 dargestellt, die gegenüber der nach Fig. 1 gewisse Vereinfachungen aufweist. Das Stützrohr 31 ist hierbei - wie sich aus den Querschnitten nach Fig. 5 und 6 ergibt - als zum Beispiel Sechskantrohr ausgebildet, wobei in die außenliegenden Konturen ebenfalls ein Gewinde 32 eingeschnitten ist. Das im Unterteil zylindrischen Fußrohr 33 ist im oberen Bereich 34 entsprechend der Außenkontur des Stützrohres 31 als Sechskant gepreßt und stellt damit die Verdrehsicherung für das Stützrohr 31 dar. Der auf das Stützrohr 31 aufgeschraubte Stellring 35 liegt somit unmittelbar auf der Oberkante 6 des Fußrohres 33 auf. Durch entsprechendes Verdrehen dieses Stellringes 35 wird das Stützrohr 31 in seiner Höhe - ohne sich selbst zu verdrehen - verstellt.FIG. 4 shows a further advantageous embodiment of such a support 30, which has certain simplifications compared to that of FIG. 1. The support tube 31 is - as can be seen from the cross sections according to FIGS. 5 and 6 - designed as a hexagonal tube, for example, a thread 32 also being cut into the outer contours. The base tube 33, which is cylindrical in the lower part, is pressed as a hexagon in the upper region 34 corresponding to the outer contour of the support tube 31 and thus represents the anti-rotation device for the support tube 31. The adjusting ring 35 screwed onto the support tube 31 thus lies directly on the upper edge 6 of the base tube 33 . By turning this adjusting ring 35 accordingly, the height of the support tube 31 is adjusted, without twisting itself.

Zur Justierung und Arretierung ist - wie insbesondere aus Fig. 5 zu ersehen ist - der Stellring 35 auf seiner Unterseite mit einer Eindrückung 37 entsprechend der Kontur der Oberkante 36 des Fußrohres 33 versehen, wodurch der Stellring 35 jeweils nach einer Verdrehung um 60° einrasten und damit arretiert werden kann.For adjustment and locking - as can be seen in particular from FIG. 5 - the adjusting ring 35 is provided on its underside with an indentation 37 corresponding to the contour of the upper edge 36 of the foot tube 33, whereby the adjusting ring 35 snaps in after each rotation and so that can be locked.

Die am oberen Ende des Stützrohres 31 aufgeschweißte Stützplatte 40 ist noch einmal in Aufsicht in Fig. 7 dargestellt. Auf diese Stützplatte 40 können unmittelbar oder über eine entsprechend geformte Zwischenplatte aus Kunststoff jeweils die Ecken vier benachbarter Bodenplatten aufgelegt werden. Zur Einsparung der Anzahl der zu verwendenden Stützen 10 oder 30 oder zur Erhöhung der Traglast ist es jedoch auch möglich, zwischen im jeweils doppelten Abstand der Breite einer Bodenplatte angeordnete Stützentraversen 41 anzuordnen, auf die die Bodenplatten dann aufgelegt werden. Zur Halterung dieser Traversen 41 sind in die Stützplatte 40 radial verlaufende schlitzförmige Ausnehmungen 42 eingelassen, in die dann senkrecht abgewinkelte Lappen 43 der horizontal aufgelegten Traversen 41 eingreifen, wie man das insbesondere auch aus dem Querschnitt nach Fig. 8 ersieht. Damit werden die Traversen 41 exakt und sicher fixiert, wobei bei entsprechenden Toleranzen von Ausnehmung 42 und abgewinkelten Lappen 43 noch gewisse Längendifferenzen ausgeglichen werden können.The support plate 40 welded onto the upper end of the support tube 31 is shown again in a top view in FIG. 7. The corners of four adjacent base plates can be placed on this support plate 40 directly or via an appropriately shaped plastic intermediate plate. In order to save the number of supports 10 or 30 to be used or to increase the load capacity, it is also possible, however, to arrange support crossbeams 41, which are arranged at twice the width of a base plate, on which the base plates are then placed. To hold these cross members 41, slot-shaped recesses 42 which run radially into the support plate 40 and into which vertically angled tabs 43 of the horizontally placed cross members 41 then engage, as can be seen in particular from the cross section according to FIG. 8. The crossbeams 41 are thus fixed precisely and securely, and with corresponding tolerances of the recess 42 and angled tab 43, certain length differences can still be compensated for.

Durch die beschriebene Ausbildung der Stützen ist also eine stufenlose vertikale Verstellung der Höhe des Doppelbodens möglich, ohne daß dabei die räumliche Lage der Stützplatten 16 bzw. 40 verändert wird. Dies ist besonders dann von Vorteil, wenn eine Nachjustierung bei bereits aufgelegten Traversen 41 erfolgen soll.Due to the described design of the supports, a stepless vertical adjustment of the height of the raised floor is possible without changing the spatial position of the support plates 16 or 40. This is particularly advantageous if readjustment is to be carried out with cross members 41 already in place.
