„Doppelbodenkonstruktion" "Double floor construction"
Die Erfindung betrifft eine Doppelbodenkonstruktion mit Belagtafeln und einer auf einem Unterboden zu errichtenden Tragstruktur, auf der die Belagtafeln randseitig aneinanderstoßend im Abstand von dem Unterboden verlegbar sind, The invention relates to a double floor construction with covering panels and a support structure to be erected on a subfloor on which the covering panels can be laid at the edges in abutting relationship at a distance from the subfloor.
Aus der EP 162 733 A2 ist ein mit geringem Arbeitsaufwand verlegbarer Bodenbelag bekannt, welcher Belagtafeln umfasst, die eine steife untere Trägerschicht und eine obere, beispielsweise durch Fliesen gebildete Dekorschicht aufweisen. An die Trägerschicht und die Dekorschicht ist eine Zwischenschicht angeschäumt oder angespritzt. Die Zwischenschicht geht einstückig in eine Randeinfassung sowie in Einrichtungen zum randseitigen Verbinden der Belagtafeln über, wobei die Randeinfassung und Einrichtungen gleichzeitig mit der Zwischenschicht hergestellt sind. Der Erfindung liegt die Aufgabe zugrunde, eine neue Doppelbodenkonstruktion der eingangs erwähnten Art zu schaffen, die sich mit geringem Arbeitsaufwand herstellen lässt, die eine hohe FlOssigkeitsdichtigkeit und Luftdichtigkeit aufweist und deren Belagtafeln sich schnell auswechseln lassen. Die diese Aufgabe lösende Doppelbodenkonstruktion nach der Erfindung ist dadurch gekennzeichnet, dass die Tragstruktur Tragschienen umfasst, die sich unterhalb der Stöße zwischen den Belagtafeln entlang der Stöße erstrecken, und dass die Belagtafeln und Tragschienen Einrichtungen zum vertikalen Aufstecken der Belagtafeln auf die Tragschienen unter horizontalem Zusammenpressen der die Stöße bildenden Randseiten der Belagtafeln umfassen. Vorteilhaft sind die Belagtafeln bei der Verbindung untereinander sowie bei einer Demontage nur vertikal zu bewegen, umständliche Horizontalbewegungen zur gegenseitigen Verbindung entfallen. Jede einzelne Belagtafel lässt sich bei Bedarf leicht aus dem Flächenverband herausnehmen und z.B. gegen eine Belagtafel mit integrierter Steckdose ersetzen. Die horizontale Anpressung der Belagtafeln untereinander sorgt für Dichtigkeit des Belags. EP 162 733 A2 discloses a floor covering which can be laid with little work effort and which comprises covering panels which have a rigid lower carrier layer and an upper decorative layer formed for example by tiling. An intermediate layer is foamed or molded onto the carrier layer and the decorative layer. The interlayer is integrally formed into a skirt as well as means for marginally bonding the skin panels, with the perimeter and equipment made simultaneously with the interlayer. The invention has for its object to provide a new double floor construction of the type mentioned above, which can be produced with little effort, which has a high fluid tightness and airtightness and their Belagtafeln can be replaced quickly. The double floor construction according to the invention which achieves this object is characterized in that the support structure comprises support rails which extend beneath the joints between the cover panels along the joints, and in that the covering panels and mounting rails comprise means for vertically attaching the flooring panels to the mounting rails while horizontally compressing the panels the impact forming edge sides of the Belagtafeln include. Advantageously, the Belagtafeln in the connection with each other and in a disassembly only to move vertically, cumbersome horizontal movements account for mutual connection. If required, each individual covering panel can be easily removed from the polysurface and, for example, replaced by a covering panel with integrated socket. The horizontal pressing of the lining panels with each other ensures tightness of the covering.
In einer bevorzugten Ausführungsform der Erfindung weisen die Tragschienen einen unter dem betreffenden Stoß verlaufenden Längskanal auf, in den an den Randseiten der Belagtafeln gebildete Hakenschenkel einsteckbar sind. Beim Einstecken entstehende Querkräfte ziehen die Belagtafeln randseitig zusammen, womit vorteilhaft eine Stabilisierung und zusätzliche Abdichtung des Belags verbunden ist. Vorzugsweise sind die Belagtafeln unter Einrastung an den Tragschienen auf die Tragschienen aufsteckbar. In a preferred embodiment of the invention, the support rails have a running under the respective stroke longitudinal channel, in the formed on the edge sides of the cover panels hook legs are inserted. When inserting transverse forces arising Bellagafeln pull together edge, which is advantageous stabilization and additional sealing of the lining is connected. Preferably, the Belagtafeln be plugged under latching to the support rails on the support rails.
In weiterer Ausgestaltung der Erfindung weisen die Tragschienen ein den Längskanal bildendes U-Profil auf, das im Material von der übrigen Tragschiene abweicht. Dieses U-Profil kann z.B. mit hoher Genauigkeit aus Aluminium oderIn a further embodiment of the invention, the mounting rails have a longitudinal channel forming U-profile, which deviates in material from the rest of the mounting rail. This U-profile can e.g. with high accuracy aluminum or
Kunststoff hergestellt werden, während der Rest der Tragschiene z.B. durch ein mit größeren Fertigungstoleranzen behaftetes Stahlprofil, insbesondere Stahl-U-Profil, gebildet sein kann. Vorteilhaft weist das erstere U-Profil, an das außenseitig ein Einrastschenkei zum Einrasten in der übrigen Tragschiene angeordnet sein kann, an den Innenseiten der U-Schenkel je einen Vorsprung, insbesondere einen Rastvorsprung auf, an dem der genannte Hakenschenkel einrastet. In weiterer Ausgestaltung der Erfindung sind Einrichtungen zum vertikalen Aufstecken der Belagtafeln auf die Tragschienen an einer zwischen einer Trägerschicht und einer Dekorschichf angeschäumten oder angespritzten Zwischenschicht der Belagtafel angeformt. Diese Zwischenschicht kann z.B. aus Polyurethanschaum bestehen. Plastic are made while the rest of the mounting rail, for. may be formed by a steel profile subject to larger manufacturing tolerances, in particular steel U-profile. Advantageously, the former U-profile, on the outside of a Einrastschenkei can be arranged to engage in the rest of the support rail, on the inner sides of the U-legs each have a projection, in particular a locking projection on which the said hook leg snaps. In a further embodiment of the invention, means for vertical attachment of the lining panels are integrally formed on the mounting rails on a foamed or molded between a carrier layer and a Dekorschichf intermediate layer of the covering panel. This intermediate layer may e.g. Made of polyurethane foam.
Das den Längskanal bildende U-Profll stellt nach den randseitig unter horizontalem Anpressdruck aneinander stoßenden Belagtafeln und den über die Zwischen- Schicht hergestellten Nut-/Federverbindungen zwischen den Belagtafeln und den über die Zwischenschicht hergestellten Nut-/Federverbindungen zwischen den Belagtafeln und dem U-Profil gewissermaßen eine dritte Dichtungsebene dar, in dem das U-Profil nach unten geschlossen ist. The U-profile, which forms the longitudinal channel, adjusts to the edge plates under horizontal contact pressure abutting Belagtafeln and over the intermediate Layer produced tongue and groove joints between the Belagtafeln and the groove / spring connections between the Belagtafeln and the U-profile produced via the intermediate layer, so to speak, a third sealing plane in which the U-profile is closed down.
In einer Ausführungsform der Erfindung umfasst die Tragstruktur Ständerelemente zur Aufnahme der Tragschienen, die vorzugsweise zur Anordnung unterhalb der Ecken der Belagtafeln vorgesehen sind. In one embodiment of the invention, the support structure includes stand elements for receiving the support rails, which are preferably provided for arrangement below the corners of the Belagtafeln.
Diese Ständerelemente können Sitze, vorzugsweise Randeinschlitzungea für die Aufnahme von Tragschienen umfassen, die über mehrere Ständerelemente durchgehend verlegt sind. Vorteilhaft umfasst die Tragstruktur ferner Tragschienen, die sich zwischen den über mehrere Ständerelemente durchgehend verlegten Tragschienen zu diesen senkrecht erstrecken. These stand elements may include seats, preferably edge Einschlitzungea for receiving mounting rails, which are laid through several stator elements throughout. Advantageously, the support structure further comprises support rails which extend perpendicularly between the support rails which are laid continuously over a plurality of uprights.
Diese sich zwischen den durchgehend verlegten Tragschienen erstreckenden Tragschienen sind zweckmäßig an den Ständerelementen einhängbar. These extending between the continuously installed mounting rails mounting rails are conveniently suspended from the stand elements.
In weiterer Ausgestaltung der Erfindung umfassen die Ständerelemente eine ver- stellbare Drei- oder Vierpunktauflage zur Aufständerung auf dem Unterboden. Die Verstellung kann unter Veränderung von Höhe und Neigung des Ständerelements z.B. durch Manipulation von oben erfolgen, indem ein Werkzeug von oben in eine Hülse eingeführt wird, in die von unten ein Ständerfuß mit einer Eingriffsöffnung für das Werkzeug am oberen Ende eingeschraubt ist. In a further embodiment of the invention, the stand elements comprise an adjustable three- or four-point support for elevation on the underbody. The adjustment may be effected by changing the height and inclination of the upright element e.g. by manipulation from above done by a tool is inserted from above into a sleeve into which a stand base is screwed with an engagement opening for the tool at the top.
In einer weiteren Ausführungsform kann die Drei- oder Vierpunktauflage durch Femwirkung durch die verlegten Belagfafeln hindurch verstellbar sein, z.B. durch Magnetwirkung. Zum Beispiel ein über eine Magnetkupplung von außen bewegtes Getriebe kann zur Höhenverstellung benutzt werden. Eine Nachjusfierung des fertigveiiegten Bodenbelags ist auf solche Weise möglich. Vorzugsweise wird die Tragsfruktur jedoch vor dem Verlegen der Belagtafeln genau justiert. In a further embodiment, the three- or four-point support may be adjustable by the effect of the laid covering panels, e.g. by magnetic action. For example, a via a magnetic coupling moved from the outside gearbox can be used for height adjustment. A Nachjusfierung the fertigveiiegten flooring is possible in such a way. Preferably, however, the support structure is precisely adjusted prior to laying the cover panels.
Eine Verstellung kann z.B. auch mittels nur einer im Kreuzungspunkt der Fugen zwischen den Belagtafeln angeordneten Schraube möglich sein. Eine Durchsteck- Öffnung für ein Drehwerkzeug ließe sich mit Hilfe einer zwecks Justierung abnehmbaren Kappe verschließen. Auch auf diese Weise kann ohne Entfernen von Belagtafeln eine Nachjustierung des Bodenbelags erfolgen. Vorzugsweise sind die Ständerelemente als an einer oder zwei einander gegenüberliegenden Seiten offene Quader ausgebildet, wobei die einander gegenüberliegenden Quaderwände am freien oberen Rand eine Randausnehmung, insbesondere Randeinschlitzungen zur Bildung des oben genannten Sitzes oder zur Bildung von Einrichtungen zum Einhängen der Tragschienen, aufweisen. An adjustment can for example be possible by means of only one arranged at the intersection of the joints between the Belagtafeln screw. A push-through opening for a turning tool could be closed by means of a removable cap for adjustment. Also in this way can be done without removing Belagtafeln a readjustment of the flooring. Preferably, the uprights elements are formed as cuboid open on one or two opposite sides, wherein the opposing parallelepiped walls at the free upper edge of an edge recess, in particular Randeinschlitzungen to form the above seat or to form means for suspending the support rails have.
Die senkrechten Ständerelemente lassen sich leicht zunächst allein aufstellen. In diese werden dann die über mehrere Ständerelemente durchgehenden, horizontal auszurichtenden Tragschienen eingesetzt. Anschläge, insbesondere Ein- schlitzungen daran, können die genaue Position der Sfänderelemente fixieren. Alternativ können die Tragschienen Markierungen für die Position der Ständerelemente aufweisen. Zwischen zwei so hergestellten Längsträgern können dann die dazu senkrechten, Koppelträger zwischen zwei Längsschienen bildenden Tragschienen an den Ständerelementen eingehängt werden. So entstehen pass- genaue Quadrataufnahmen, die die mit Einrastelementen versehenen Belagtafeln aufnehmen und untereinander verspannen.  The vertical stand elements can be easily set up alone. In this then the continuous over several stator elements, horizontally aligned mounting rails are used. Stops, in particular slits thereon, can fix the exact position of the string elements. Alternatively, the mounting rails may have markings for the position of the stator elements. Between two longitudinal beams produced in this way, the support beams, which are perpendicular thereto, can then be suspended from the support elements between two longitudinal rails forming support rails. This results in perfectly fitting square shots, which pick up the lining panels provided with snap-in elements and clamp them together.
Zum Verspannen können unter Selbstjustierung des Bodenbelags auch die Belagtafeln selbst dienen, insbesondere dann, wenn Bewegungsspielraum in den Rast- Verbindungen besteht. Die passgenauen Belagtafeln justieren dann ringsum- laufend die Tragkonstruktion und bringen die Trägerelemente in die exakten Positionen. For bracing under self-adjustment of the flooring and the Belagtafeln serve themselves, especially if there is room for maneuver in the snap-in connections. The precisely fitting lining panels then adjust the support structure around the circumference and bring the support elements into their exact positions.
Die sich zwischen den durchgehend verlegten Tragschienen erstreckenden kürzeren Koppel-Trägerschienen können an ihren Enden Schlitze zum Einhängen an den Ständerelementen aufweisen. The extending between the continuous support rails shorter coupling carrier rails may have slots for hanging on the stator elements at their ends.

Eine Doppelbodenkonstruktion umfasst in dem gezeigten Ausführungsbeispiel quadratische Belagtafeln 1 , die randseitig aneinanderstoßend auf einer Tragstruktur verlegt sind. Es können aber auch rechteckige Belagtafeln eingesetzt werden, ggf. unter Weglassung eines eingehängten Koppelträgers. Die auf einem Unterboden aufgeständerte Tragstruktur umfasst jeweils unter den Ecken der aneinanderstoßenden Belagtafeln 1 angeordnete Ständerelemente 2. In the exemplary embodiment shown, a double floor construction comprises square covering panels 1, which are laid on the support structure at the edges in a contiguous manner. But it can also be used rectangular Belagtafeln, possibly omitting a hinged coupling carrier. The support structure raised on a subfloor comprises in each case under the corners of the adjoining lining panels 1 arranged stator elements. 2
Auf den Ständerelementen 2 sind zueinander senkrechte Tragschienen 3 und 4 angeordnet, von denen sich die Tragschienen 3 jeweils durchgehend über mehrere Ständerelemente 2 hinweg und die Tragschienen 4 jeweils nur zwischen zwei solchen Tragschienen 3 und zwei Ständerelementen 2 erstrecken. On the uprights 2 mutually perpendicular support rails 3 and 4 are arranged, of which the support rails 3 each extend continuously over a plurality of stator elements 2 away and the support rails 4 only between two such support rails 3 and two stator elements 2.
Wie Fig. ό und 7 erkennen lassen, bestehen die Belagtafeln 1 aus mehreren Schichten, einer steifen Trägerschicht 5, einer Dekorschicht 6 und einer an die Trägerschicht 5 und die Dekorschicht 6 angeschäumten oder angespritzten Zwischenschicht 7. Die steife, der Belagtafel Stabilität verleihende Trägerschicht 5 ist vorzugsweise aus einem Recyclingmaterial oder einem nicht brennbaren, sonstigen Material (z.B. einer Gipsfaserplatte o.ä.) hergestellt. Die Dekorschicht kann z.B. Fliesen oder ein anderes Material mit dekorativer Oberfläche aufweisen. Die angeschäumte oder angespritzte Zwischenschicht 7 besteht vorzugsweise aus Polyurethanschaum. Die Zwischenschicht 7 geht einstückig in eine um die Belagtafel 1 umlaufende Randeinfassung 8 über, welche mit der Randeinfassung der jeweils benachbarten Belagtafel einen Stoß 9 bildet. Ferner einstückig mit der Zwischenschicht 7 verbunden ist ein Hakenschenkel 10. Sowohl der Hakenschenkel 10 als auch die Randeinfassung 8 sind gleichzeitig mit der Zwischenschicht 7 durch Anschäumen oder Anspritzen hergestellt. Es können aber auch fertige Verbindungselemente (z.B. Strangziehteile) ersatzweise mit eingeschäumt werden. Im Unterschied zu der umlaufenden Randeinfassung 8 sind die Hakenschenkel 10 nicht umlaufend sondern nahe den Tafelecken unterbrochen. As can be seen in FIGS. 7 and 7, the covering panels 1 consist of several layers, a stiff carrier layer 5, a decorative layer 6 and an intermediate layer 7 which is foamed or molded onto the carrier layer 5 and the decorative layer 6. The rigid carrier layer 5 which gives stability to the covering plate is preferably made of a recycled material or a non-combustible, other material (eg a gypsum fiberboard or the like). The decorative layer may have, for example, tiles or another material with a decorative surface. The foamed or injection-molded intermediate layer 7 is preferably made of polyurethane foam. The intermediate layer 7 merges integrally into a peripheral rim 8 surrounding the covering panel 1, which forms a joint 9 with the edge enclosure of the respectively adjacent covering panel. Further, integrally connected to the intermediate layer 7 is a hook leg 10. Both the hook leg 10 and the edge enclosure 8 are made simultaneously with the intermediate layer 7 by foaming or molding. But it can also be ready foamed-up finished fasteners (eg extruded parts). In contrast to the peripheral edge enclosure 8, the hook legs 10 are not circumferentially interrupted but near the corners of the table.
Die Ständerelemenfe 2 sind im Wesentlichen als hohle, aneinander gegenüberliegenden Seiten offene Quader mit quadratischem horizontalem Querschnitt und vier Seitenwänden 1 1 hergestellt. Die Seitenwände 1 1 gehen an den Ecken jeweils in eine vertikale Hülse 12 mit einem Innengewinde über. In die Hülsen 12 sind Ständerfüße 13 eingeschraubt. Gewindebolzen der Ständerfüße 13 weisen zweckmäßig am oberen Ende eine Ausnehmung für den Eingriff eines in die Hülse 12 von oben her einführbaren Drehwerkzeugs auf. Bei Herstellung des Grundkörpers der Ständerelemente als Strangziehteil werden die genannten Innengewinde durch Einpresshülsen gebildet. The Ständerelemenfe 2 are essentially as hollow, opposite sides open cuboid having a square horizontal cross-section and four side walls 1 1 manufactured. The side walls 1 1 go at the corners in each case in a vertical sleeve 12 with an internal thread. In the sleeves 12 stand feet 13 are screwed. Threaded bolts of the stand feet 13 expediently have at the upper end a recess for the engagement of a sleeve 12 insertable from above rotary tool. When producing the main body of the stator elements as extruded part, said internal threads are formed by press-fit sleeves.
Jede der Seitenwände 1 1 weist am oberen Rand zwei Randeinschlitzungen auf. Each of the side walls 1 1 has at the top two Randeinschlitzungen.
Sowohl die durchgehenden Tragschienen 3 als auch die kürzeren Tragschienen 4 bestehen in dem gezeigten Beispiel jeweils aus einem U-förmigen Profil 15 aus Stahl und einem ein U-Profil umfassenden Profil 16, das z.B. aus Aluminium oder einem Kunststoff besteht. Eine Einformung 1 7 im Basisschenkel des Stahlprofils 15 nimmt das Profil 16 auf, dessen ßasisschenkel außenseitig einen Vorsprung 18 aufweist. Weitere Vorsprünge 1 sind in dem Profil 16 innenseitig an den Enden der U- Schenkel gebildet. Es handelt sich hierbei um Rastnasen für den Eingriff in eine Ver- tiefung 20 im Hakenschenkel 10. Die Rastnasen bilden eine zweite Dichtebene.Both the continuous support rails 3 and the shorter support rails 4 in the example shown each consist of a U-shaped profile 15 made of steel and a profile 16 comprising a U-profile, which is e.g. made of aluminum or a plastic. An indentation 1 7 in the base leg of the steel section 15 receives the profile 16, whose ßasisschenkel has a projection 18 on the outside. Further projections 1 are formed in the profile 16 on the inside at the ends of the U-legs. These are latching lugs for engagement in a depression 20 in the hook leg 10. The latching lugs form a second sealing plane.
Die Profile 15,16 könnten abweichend von einem U-Profil geformt sein, und es kommen dafür auch andere als die genannten Materialien in Betracht. The profiles 15, 16 could be deviated differently from a U-profile, and other materials than those mentioned may also be considered.
Sowohl die Tragschienen 3 als auch die Trageschienen 4 weisen Randeinschlitzun- gen 21 in beiden Schenkeln des U-Profils 15 auf. Bei der Herstellung einer Doppelbodenkonstruktion aus den vorangehend beschriebenen Bauteilen werden zunächst die Ständerelemente 1 in den den aneinderstoßenden Ecken der Belagtafeln 1 entsprechenden Positionen auf dem Unterboden angeordnet. Darauf erfolgt die Verlegung der durchgehenden Trag- schienen 3, deren Stahlprofile 15 mit ihren U-Schenkel in die betreffenden Rand- einschlitzungen 1 in den Seitenwänden 1 1 der Tragelemente 2 eingreifen. Die Schlitze 21 in den U-Schenkeln sorgen automatisch für eine maßgenaue Anordnung der Trägerschienen 3,4. Alternativ könnte statt der Schlitze 21 an den Trägerschienen 3 oder/und 4 eine Markierung angebracht sein, die eine maßgenaue Verlegung der Tragstruktur erleichtert, durch Längsverschiebung der Tragschienen 3 oder/und 4 aber noch einen Toleranzausgleich zulässt. Ohne auf die Abmessungen der Belagtafeln zugeschnittene Einschiitzungen 21 oder sonstige die Tragschienen 3,4 auf den Tragelementen 2 horizontal festlegende Anschläge, kann variabel eine Anpassung an unterschiedliche Abmessungen von Belagtafeln erfolgen. Gegebenenfalls sind nur die Tragschienen 4 anzupassen. Both the mounting rails 3 and the support rails 4 have edge Einschlitzun- conditions 21 in both legs of the U-profile 15. In the production of a double floor construction from the components described above, first of all the stand elements 1 are arranged in the positions corresponding to the adjacent corners of the covering panels 1 on the underbody. This is followed by the laying of the continuous support rails 3, the steel profiles 15 of which engage with their U-legs in the respective edge inclusions 1 in the side walls 11 of the support elements 2. The slots 21 in the U-legs automatically ensure a dimensionally accurate arrangement of the support rails 3,4. Alternatively, instead of the slots 21 on the support rails 3 and / or 4, a mark could be attached, which facilitates a dimensionally accurate installation of the support structure, but by tolerance displacement can be compensated by longitudinal displacement of the support rails 3 and / or 4. Without on the dimensions of the Belagtafeln tailored Einschiitzungen 21 or other the support rails 3.4 on the support elements 2 horizontally defining stops, can be variably adapted to different dimensions of Belagtafeln. Optionally, only the mounting rails 4 are adjusted.
Die Tragkonstruktion kann nun justiert werden, indem bei horizontaler Ausrichtung der Tragschienen 3,4 die verstellbaren Ständerfüße 13 der Ständerelemente 2 durch mehr oder weniger weites Eindrehen in die Hülsen 12 so mit Hilfe eines Drehwerkzeugs von oben eingestellt werden, so dass jedes der Ständerelemente 2 kippstabil auf dem Unterboden steht. The support structure can now be adjusted by horizontally aligning the support rails 3.4, the adjustable stand feet 13 of the stator elements 2 are adjusted by more or less wide screwing into the sleeves 12 so using a turning tool from above, so that each of the stator elements 2 is stable against tilting stands on the subsoil.
Abschließend lassen sich die Belagtafeln I montieren, deren Hakenschenkel 10 in den z.B. durch das Aluminium-Profil 16 gebildeten Kanal eingesteckt werden, wobei die Ränder der Belagtafeln 2 aneinander gedrückt werden und den Stoß 9 bilden. Finally, the cover panels I can be mounted, the hook legs 10 in the example. be formed by the aluminum profile 16 formed channel, wherein the edges of the Belagtafeln 2 are pressed against each other and form the shock 9.
Zum Schluss werden die Belagtafeln unter vertikalem Andruck eingesetzt. Die entsprechend den Abmessungen der Belagtafeln vorgesehenen Einschiitzungen können Spielräume derart aufweisen, dass die Tragschienen in ihrer Lage ringsumlaufend den höchstgenauen Hakenelementen der Belagtafeln folgen. Entsprechend sorgt der durch die Belagtafeln gebildete Oberbelag horizontal für eine exakte Justierung des Gesamtsystems. Die Ständerelemente könnten auch eine solche Höhe aufweisen, dass durch den Belag beispielsweise ein Bühnenboden herstellbar ist. Hierzu könnte eine festere Kopplung zwischen den Tragschienen und den Ständerelementen, beispielsweise durch Verschraubung, vorgesehen werden. Finally, the panels are used under vertical pressure. The Einschiitzungen provided according to the dimensions of the Belagtafeln may have clearances such that the mounting rails in their position around the circumference follow the most accurate hook elements of Belagtafeln. Accordingly, the top surface formed by the lining panels ensures horizontal adjustment of the entire system. The stand elements could also have such a height that, for example, a stage floor can be produced by the covering. This could be a firmer Coupling between the support rails and the stator elements, for example by screwing, can be provided.
Alternativ könnten, insbesondere bei größeren Höhen, Queraussteifungen, Dia- gonalverbände oder ähnliches vorgesehen werden. Alternatively, transverse reinforcements, diagonal braces or the like could be provided, in particular at high altitudes.
Es wird nun auf Fig. 8 Bezug genommen, wo ausschnittsweise ein weiteres Ausführungsbeispiel für einen Doppelbodenbelag gezeigt ist. Gleiche oder gleichwirkende Teile sind mit derselben Bezugszahl wie bei dem vorangehenden Aus- führungsbeispiel bezeichnet, wobei der betreffenden Bezugszahl der Buchstabe a beigefügt ist. Reference is now made to Fig. 8, where a further embodiment of a double floor covering is shown in detail. Identical or equivalent parts are designated by the same reference number as in the previous embodiment, the relevant reference number being appended to (a).
Von dem vorangehenden Ausführungsbeispiel unterscheidet sich das Ausführungsbeispiel von Fig. 8 vor allem dadurch, dass an einander gegenüberliegenden Randeinfassungen 8a von Belagtafeln 1 a ein weiterer Rastvorsprung 22 und eine Rastvertiefung 23 vorgesehen sind. Of the preceding embodiment, the embodiment of Fig. 8 differs mainly by the fact that at opposite edge borders 8a of Belagtafeln 1 a, a further latching projection 22 and a latching recess 23 are provided.
Die unter Anpressdruck aneinanderstoßenden Randeinfassungen 8a bilden eine erste Dichtebene. Für eine weitere Abdichtung des Doppelbodenbelags sorgt der in die Rastvertiefung 23 eingreifende Rastvorsprung 22. Schließlich lässt ein nach unten geschlossenes U-Profil 1 όα, in welches Stecknasen 1 Oa der Randeinfassungen 8a eingreifen, als dritte Dichtungsbarriere nach unten keinerlei Flüssigkeit hindurch. in Fig. 9 und 10 ist ein Ständerelement 2b gezeigt, das einen unteren Teil 25 aufweist, der in seiner Grundform dem in Fig. 2 gezeigten Ständerelement 2 entspricht. Den Ständerfüßen 13 entsprechende Ständerfüße sind in den Figuren 9 und 10 nicht gezeigt. In jede von vier vertikalen Hülsen 12b ist an deren oberem Ende drehfest eine Gewindebuchse 26 eingesetzt. The abutting edge pressure under pressure 8a form a first sealing plane. Finally, a downwardly closed U-profile 1 όα, in which lugs 1 Oa of the edge surrounds 8a engage, as a third sealing barrier down no liquid through it. 9 and 10, a stator element 2b is shown, which has a lower part 25 which corresponds in its basic form to the stator element 2 shown in FIG. The stand feet 13 corresponding stand feet are not shown in Figures 9 and 10. In each of four vertical sleeves 12b, a threaded bush 26 is rotatably inserted at its upper end.
Neben dem unteren Teil 25 weist das Ständerelement 2b einen oberen Teil 27 auf, der im horizontalen Querschnitt wie der untere Teil 25 ausgebildet ist und an dessen oberen Rand (nicht gezeigte) Einschiitzungen für das Einhängen von Trägerschienen gebildet sind. Auf einer auf den unteren Teil 25 aufsetzbaren Zwischenplatte 28 ist ein Zahnrad 29 drehbar gelagert, von dem axial eine Magnetkupplungseinrichtung 30 vorsteht. In addition to the lower part 25, the stator element 2b has an upper part 27, which is formed in the horizontal cross section as the lower part 25 and at the upper edge (not shown) Einschiitzungen for the suspension of carrier rails are formed. On a mountable on the lower part 25 intermediate plate 28, a gear 29 is rotatably mounted, projecting axially from the magnetic coupling means 30.
Das Zahnrad 29 steht im Eingriff mit vier auf der Zwischenplatte 28 drehbar gelagerten Zahnrädern 31 , die jeweils drehfest von einem Gewindebolzen 32 durchsetzt sind. Jeder der Gewindebolzen 32 greift in eine der Gewindebuchsen 26 ein. The gear 29 is in engagement with four rotatably mounted on the intermediate plate 28 gears 31, which are each rotatably penetrated by a threaded bolt 32. Each of the threaded bolts 32 engages in one of the threaded bushings 26.
Mit Hilfe eines in Fig. 10 gezeigten Magnetdrehwerkzeugs 33 kann noch nach Ver- legung von Belagtafeln 1 b eine Höhenjustierung des oberen Teils 27 des Ständerelements 2b erfolgen. Bei Drehung der Magnetkupplungseinrichtung 30 durch das Magnetdrehwerkzeug 33 treibt das Zahnrad 29 die vier Zahnräder 31 an, so dass sich die vier Gewindebolzen 32 mitdrehen und aus den Gewindebuchsen 26 unter Anhebung des oberen Teils 27 heraustreten. Durch Links-/Rechtsgewinde ist eine Wirkung in beiden Richtungen möglich. With the aid of a magnetic turning tool 33 shown in FIG. 10, height adjustment of the upper part 27 of the upright element 2b can take place even after laying of covering sheets 1b. Upon rotation of the magnetic coupling device 30 by the magnetic rotary tool 33, the gear 29 drives the four gears 31, so that the four threaded bolts 32 rotate and emerge from the threaded bushing 26 by raising the upper part 27. By left / right-hand thread an effect in both directions is possible.
Abweichend von dem gezeigten Ausführungsbeispiel könnten Gewindebuchsen auch oder nur am oberen Teil 27 vorgesehen oder drehfest mit der Zwischenplatte 28 verbunden sein. Es versteht sich, dass dies entsprechende Kombinationen von Rechts- und Linksgewinden erfordert. Notwithstanding the embodiment shown, threaded bushes could also or only be provided on the upper part 27 or rotatably connected to the intermediate plate 28. It is understood that this requires appropriate combinations of right and left hand threads.
Abweichend von dem vorangehend beschriebenen Ausführungsbeispiel können die Tragschienen 3,4 einstückig, z.B. aus gebogenem Stahlblech, hergestellt sein. Die Figuren 1 1 bis 13 zeigen verschiedene Ausführungsbeispiele solcher Trag- schienen im Querschnitt. Die Tragschienen bilden jeweils einen Längskanal 40, in den die an den Randseiten der Belagtafeln gebildeten Hakenschenkel einsteckbar sind. Notwithstanding the embodiment described above, the support rails 3,4 can be made in one piece, e.g. made of bent sheet steel. Figures 1 1 to 13 show various embodiments of such support rails in cross section. The mounting rails each form a longitudinal channel 40 into which the hook legs formed on the edge sides of the Belagtafeln can be inserted.
Das Profil 16 der weiter oben beschriebenen zweiteiligen Tragschienen 3,4 ließe sich statt aus Aluminium auch aus noch besser leitfähigem Kupfer, z.B. durch Strangziehen, herstellen. Insbesondere solche Profile können in Verbindung mit leitfähigen Belagtafeln vorteilhaft zur Ableitung von Elektrizität auf dem Oberbelag dienen. Die in den Längskanal des Profils 1 ό eingreifenden, mit dem Fugenmaterial einstückig verbundenen Hakenschenkel lassen sich z.B. aus leitfähigem Poly- urethan bilden. Über die Profile 16 können dann definierte Ableitströme fließen. Eine in Fig. 1 gezeigte Querversteifung 41 zwischen verlängerten Ständerelementen 2a und 2a" eines [im Übrigen nicht gezeigten] Bühnenbodens, lässt sich mit Hilfe einer in Fig. 15 dargestellten Schnellverspannung jeweils bei 42 befestigen. Die Schnellverspannung umfasst ein Außenrohr 43 und ein in dem Außenrohr 43 geführtes Innenrohr 44, das an einem Ende mit einem Klemmkopf 45 verbunden ist. Ein in einer Ausnehmung 46 des Außenrohrs bei 47 drehbar gelagerter Kniehebel 48 greift mit einem Exenterkopf 49 in eine Ausnehmung 50 im Innenrohr 44 ein. Durch Verschwenkung des Kniehebels 48 gemäß Pfeil 51 lässt sich der durch eine Öffnung 53 in einer Wand 52 des Ständerelements 2a bzw. 2a' geführte, die Wand 52 hintergreifende Klemmkopf 45 in Richtung des Pfeils 54 bewegen und die Wand 52 zwischen dem Stirnende des Außenrohrs 43 und dem Klemmkopf 45 einklemmen. The profile 16 of the above-described two-part mounting rails 3.4 could be made of aluminum instead of even better conductive copper, for example by pultrusion. In particular, such profiles can be used in conjunction with conductive Belagtafeln advantageous for the dissipation of electricity on the upper surface. The hook legs which engage in the longitudinal channel of the profile 1 ό and are integrally connected to the joint material can be formed, for example, from conductive polyurethane. Defined discharge currents can then flow via the profiles 16. A transverse reinforcement 41 shown in Fig. 1 between extended upright elements 2a and 2a "of a stage floor (not shown) can be fixed at 42 by means of a quick tensioning shown in Fig. 15. The fast tensioning comprises an outer pipe 43 and an in the An outer tube 43 guided inner tube 44 which is connected at one end to a clamping head 45. A in a recess 46 of the outer tube at 47 rotatably mounted toggle lever 48 engages with an Exenterkopf 49 in a recess 50 in the inner tube 44. By pivoting the toggle lever 48 Arrow 51 can be through a hole 53 in a wall 52 of the stator element 2a and 2a 'guided, the wall 52 engages behind the clamping head 45 move in the direction of arrow 54 and clamp the wall 52 between the front end of the outer tube 43 and the clamping head 45.
Durch Verschraubung längsverschiebbare und so klemmende Konstruktionen wären ebenfalls möglich.  By screwing longitudinally displaceable and so clamping constructions would also be possible.
