Abstract
Description
Die Erfindung betrifft ein flüssigkeitsdichtes Großflächenplattensystem aus rechteckigen, insbesondere quadratischen Betonplatten mit konstruktiver Armierung, die untereinander durch sowohl in der Ebene der Fläche als auch senkrecht dazu wirkenden, seitlich an benachbarten Platten angeschlossenen Kupplungselementen formschlüssig verriegelbar sind und deren Fugen durch eine Dichtung verschlossen sind, wobei die Kupplungselemente als in der Betonplatte eingegossene Anker ausgebildet sind und ihre aus den Seiten benachbarter Betonplatten herausragenden Enden fluchtend ausgerichtete Ausnehmungen aufweisen, in denen ein eingetriebener, in der Ebene der Betonplatte liegender Dorn formschlüssig sitzt.The invention relates to a liquid-tight Large area plate system made of rectangular, in particular square concrete slabs with structural reinforcement, the one another by both in the plane of the surface as well as acting perpendicular to it, sideways Coupling elements connected to adjacent plates are positively lockable and their joints through a seal are closed, the Coupling elements as cast in the concrete slab Anchors are formed and their from the sides aligned ends of adjacent concrete slabs protruding have aligned recesses in which a driven, lying in the plane of the concrete slab Mandrel sits positively.
Solche Großflächenplattensysteme, bei den Plattenformate von ca. 2 m Kantenlänge üblich sind, finden vorzugsweise Verwendung an Orten, wo mit für das Erdreich schädlichen Flüssigkeiten, wie Mineralölstoffen und Chemikalien, hantiert wird. Beispiele für solche Orte sind Tankstellen und Abfüllanlagen. Da diese Orte mit zum Teil schwergewichtigen Fahrzeugen befahren werden, wird von dem Großflächenplattensystem nicht nur verlangt, daß es die Oberfläche vollständig abdichtet, sondern auch, daß die verlegten Platten die Last der Fahrzeuge aufnehmen können. Such large-area plate systems, in the plate formats of about 2 m edge length are common, preferably Use in places where harmful to the soil Liquids, such as mineral oils and chemicals, is handled. Examples of such places are petrol stations and filling lines. Because some of these places heavy vehicles are driven by the large-area panel system not only requires that it the surface completely seals, but also that the installed panels bear the load of the vehicles can.
Bei einem bekannten, auch in der Praxis eingesetzten Großflächenplattensystem der eingangs genannten Art erfolgt die Verbindung benachbarter Platten miteinander mittels zwei verschiedenartiger Kupplungselemente. Im Kreuzungsbereich von vier Platten ist in den Fugen ein Kreuzverbinder eingesetzt, der mit seinen Köpfen Vorsprünge an den Seiten der Platten hintergreift. Mit diesem Kreuzverbinder werden die Platten in horizontaler Richtung fixiert. Zur Fixierung der Platten in vertikaler Richtung sind an den gegenüberliegenden Seiten benachbarter Platten jeweils zwei Paar in Kantenlängsrichtung verlaufende Stege angebracht, in denen ein gemeinsamer Keil sitzt.In a known, also used in practice Large area panel system of the type mentioned at the beginning adjacent plates are connected to each other by means of two different coupling elements. in the The intersection of four panels is in the joints Cross connector used, the with his heads Grips behind the projections on the sides of the plates. With With this cross connector, the panels become horizontal Direction fixed. For fixing the plates in a vertical position Direction are on opposite sides neighboring plates two pairs each Ridges running in the longitudinal direction, in who have a common wedge.
Ein solches Kupplungssystem ist wegen der verschiedenartigen Kupplungselemente für die horizontale und für die vertikale Verriegelung der Platten untereinander sowohl in der Herstellung als auch in der Montage aufwendig.Such a clutch system is because of various types of coupling elements for horizontal and for the vertical locking of the plates with each other both in the production and in the Assembly complex.
Bei einem anderen aus der Patentliteratur bekannten Plattensystem (DE 39 09 803 A1) sind die benachbarten Platten in Horizontairichtung und in Vertikalrichtung mit einer Art von Kupplungselementen miteinander verbunden. Die Kupplungselemente bestehen aus benachbarte Platten oberseitig übergreifenden Riegeln aus Flachmaterial, die an den Platten mittels Schraubenbolzen befestigbar sind, die in den Platten in eingegossenen Gewindehülsen einschraubbar sind. Bei diesem Plattensystem hängt die Lastaufnahmefähigkeit wesentlich von der Auslegung der Riegel aus Flachmaterial und deren Schraubenbefestigung ab. Da die Riegel flach in der Platitenebene liegen, sind sie zur Aufnahme sehr großer Lasten bei vertretbarer Auslegung der Riegel und der Schraubverbindung kaum geeignet. Wegen des in der Plattenebene geringen Trägheitsmomentes wirken sie beim Befahren mit schweren Fahrzeugen fast wie Scharniere, so daß sich die benachbarten Platten beim Befahren winklig zueinander stellen können.In another known from the patent literature Plate system (DE 39 09 803 A1) are the neighboring ones Panels in the horizontal direction and in the vertical direction with a kind of coupling elements connected together. The coupling elements consist of adjacent plates overlapping bars made of flat material, the can be attached to the plates by means of bolts, which are cast into the plates in threaded sleeves are screwable. With this plate system it depends Load carrying capacity depends essentially on the design of the Bolts made of flat material and their screw fastening from. Since the bars are flat in the platinum plane, are they can take very large loads with reasonable Dimensioning of the bolts and the screw connection hardly suitable. Because of the small in the plate level Moment of inertia they act when driving with heavy Vehicles almost like hinges, so that the neighboring plates at an angle to each other when driving can put.
Aus der GB 226 057 ist ferner ein Großflächenplattensystem aus rechteckigen Betonplatten mit konstruktiver Armierung bekannt, bei dem benachbarte Betonplatten über Kupplungselemente formschlüssig miteinander verriegelbar sind. Die Kupplungselemente werden durch Teile der Armierung der Betonplatte gebildet, deren Stäbe teilweise über den Rand der Betonplatte hinausragen und zur Bildung eines Kupplungselementes derart umgebogen sind, daß sie an ihrem äußern Ende eine Öse bilden. Die ösenförmigen Kupplungselemente benachbarter Platten werden zur Verbindung der einzelnen Platten miteinander in eine fluchtende Anordnung gebracht und über einen eingetriebenen runden Kupplungsdorn untereinander verbunden. Die runden Ösen und der sie verbindende runde Kupplungsdorn wirken beim Befahren mit schweren Fahrzeugen wie Scharniere, so daß sich die benachbarten Platten beim Befahren winklig zueinander stellen können.From GB 226 057 is also a Large area slab system made of rectangular concrete slabs known with constructive reinforcement, in the neighboring Concrete panels form-fitting via coupling elements can be locked together. The coupling elements are by parts of the reinforcement of the concrete slab formed, the bars of which partially over the edge of the Protrude concrete slab and form a Coupling element are bent so that they are form an eyelet at its outer end. The eye-shaped Coupling elements of adjacent plates become Connection of the individual plates in one brought in alignment and over one driven round coupling mandrel among themselves connected. The round eyelets and the round eyelet connecting them Coupling mandrel work when driving heavy Vehicles like hinges so that the neighboring ones Can place plates at an angle to each other when driving over them.
Der Erfindung liegt die Aufgabe zugrunde, ein Großflächenplattensystem der eingangs genannten Art zu schaffen, dessen einfach herzustellende Betonplatten leicht zu verlegen sind und nach dem Verlegen im gesamten System eine hohe Steifigkeit sowohl in der Vertikalen als auch in der Horizontalen geben.The invention is based on the object Large area plate system of the type mentioned at the beginning create its easy to manufacture concrete slabs are easy to lay and after laying throughout System high rigidity both vertically and also give horizontally.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Ausnehmung und der Kupplungsdorn einen derartig gleichen, rotationsunsymmetrischen Querschnitt aufweisen, daß die Betonplatten nicht gelenkig verbunden werden.This object is achieved in that the recess and the coupling mandrel one such have the same, non-rotational cross-section, that the concrete slabs are not articulated.
Ein solches Großflächenplattensystem erhält seine hohe Steifigkeit in der Horizontalen und in der Vertikalen durch nur eine Art von Kupplungselementen. Diese werden mit geringstem Aufwand schon beim Gießen der Betonplatten in den Betonplatten verankert. Die rotationsunsymmetrischen Ausnehmungen in den Kupplungselementen in Verbindung mit dem eingetriebenen Dorn mit entsprechendem Querschnitt verhindern, daß sich die Betonplatten zueinander bei Belastung winklig stellen. Auch sind die Betonplatten durch den formschlüssig eingetriebenen Kupplungsdorn in der Plattenebene auf Zug belastbar. Da die Kupplungselemente in den Fugen zwischen den Betonplatten angeordnet sind, können sie durch die in die Fugen einzubringende Dichtung abgedeckt werden, so daß sich im übrigen an der Oberfläche ein einheitliches Bild ergibt, das nicht durch oberflächliche Verbindungselemente gestört wird. Ein weiterer Vorteil des erfindungsgemäßen Großflächenplattensystems besteht darin, daß sich einzelne Großflächenplatten aus der Mitte des Plattenverbandes aufnehmen lassen. Dazu brauchen lediglich die allseitigen Dichtungen aufgeschnitten und die darunterliegenden Kupplungselemente gelöst zu werden. Die Platte läßt sich dann mit geeignetem Gerät senkrecht aus dem Plattenverband herausnehmen und gegebenenfalls in entsprechender Weise durch eine neue Platte ersetzen.Such a large-area panel system receives its high Rigidity in the horizontal and in the vertical through just one type of coupling element. These will with the least effort already when pouring the concrete slabs anchored in the concrete slabs. The rotationally asymmetrical recesses in the Coupling elements in connection with the driven Prevent mandrel with appropriate cross-section the concrete slabs are angled towards each other when loaded put. The concrete slabs are also through the positively driven coupling mandrel in the Board level resilient to tension. Because the coupling elements are arranged in the joints between the concrete slabs, they can be inserted through the seal in the joints be covered so that the rest of the Surface gives a uniform image that is not through superficial fasteners is disturbed. Another advantage of the invention Large area plate system is that individual large area slabs from the middle of the Let record association be recorded. Need for this only cut the seals on all sides and the coupling elements underneath to be released. The plate can then be moved vertically using a suitable device Take out of the panel association and if necessary in replace accordingly with a new plate.
Die rotationsunsymmetrischen Ausnehmungen, die im Zusammenwirken mit dem Kupplungsdorn bei Belastung ein Einknicken benachbarter Betonplatten verhindern, können verschiedene Formen haben. Vorzugsweise haben sie eine längliche und/oder prismatische Form. Wichtig ist, daß die Kupplungselemeflte nicht wie ein Scharnier wirken.The rotationally asymmetrical recesses that are in the Interaction with the coupling mandrel when loaded Can prevent neighboring concrete slabs from buckling have different shapes. They preferably have one elongated and / or prismatic shape. It's important, that the coupling elements do not act as a hinge.
Vorzugsweise sind die Ausnehmungen seitlich offen. Bei dieser Ausgestaltung lassen sich die Ausnehmungen innerhalb der Elastizitätsgrenze des Materials aufweiten, so daß ein eingetriebener Kupplungsdorn festgeklemmt gehalten wird. Dies ist besonders dann wichtig, wenn der Kupplungsdorn als Kleromdorn leicht konisch ausgebildet ist.The recesses are preferably laterally open. At the recesses can be of this configuration expand within the elastic limit of the material, so that a driven coupling pin is clamped is held. This is particularly important if the Coupling mandrel slightly conical as clerom mandrel is.
Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß von den zusammenwirkenden Kupplungselementen benachbarter Betonplatten in einer Betonplatte mindestens zwei Kupplungselemente mit Abstand voneinander und in der anderen Betonplatte zwischen den Kupplungselementen der einen Betonplatte mindestens ein Kupplungselement angeordnet sind. Mit diesen Mitteln wird eine symmetrische Belastung der Kupplungselemente erreicht. Bei sehr enger Anordnung der Kupplungselemente kann außerdem erreicht werden, daß jede Gruppe von Kupplungselementen an zwei benachbarten Seiten die benachbarten Betonplatten auch in der Horizontalen längs der Kanten festlegt. Bei sehr großformatigen Betonplatten, die, wie erwähnt, eine Kantenlänge von 2 m haben können, sollten an jedem Seitenpaar benachbarter Betonplatten mehrere Gruppen solcher Kupplungselemente vorgesehen sein.According to a further embodiment of the invention provided that of the interacting Coupling elements of adjacent concrete slabs in one Concrete slab at least two coupling elements at a distance from each other and in the other concrete slab between the Coupling elements of a concrete slab at least one Coupling element are arranged. With these means symmetrical loading of the coupling elements reached. With a very close arrangement of the coupling elements can also be achieved that each group of Coupling elements on two adjacent sides neighboring concrete slabs also horizontally along of edges. For very large format Concrete slabs, which, as mentioned, have an edge length of 2 m should have adjacent on each pair of pages Concrete slabs several groups of such coupling elements be provided.
Eine besonders einfache Ausgestaltung der Erfindung besteht darin, daß die Kupplungselemente aus Flachmaterial bestehen. Ein solches Flachmaterial läßt sich bezüglich der Ausnehmungen leicht, zum Beispiel durch Ausstanzen, herstellen. Es läßt sich auch leicht mit der Armierung der Betonplatte verbinden, indem die Kupplungselemente in ihrem eingegosseflen Teil eine Bohrung aufweisen, durch die ein Armierungseisen gesteckt ist.A particularly simple embodiment of the invention consists in that the coupling elements Flat material exist. Such a flat material leaves yourself slightly with regard to the recesses, for example by punching out. It is also easy connect to the reinforcement of the concrete slab by the Coupling elements in their molded part Have a hole through which a reinforcing iron is inserted is.

Die in Figur 1 dargestellte großflächige Betonplatte mit konstruktiver Eisenarmierung ist quaderförmig, insbesondere hat sie einen quadratischen Grundriß mit einer Kantenlänge von ca. 2 m. Eine solche Betonplatte wird wegen ihres hohen Gewichtes maschinell zusammen mit anderen Betonplatten auf einem vorbereiteten Untergrund zu einem flüssigkeitsdichten Großflächenplattensystem zusammengebaut. Nach im einzelnen noch zu beschreibender Verbindung benachbarter Betonplatten untereinander und Schließung ihrer Fugen mit einer Dichtung erhält man im Ergebnis ein flüssigkeitsdichtes Großflächenplattensystem, das mit Schwerlastfahrzeugen befahrbar ist.The large-area concrete slab shown in Figure 1 with constructive iron reinforcement is cuboid, in particular it has a square floor plan an edge length of approx. 2 m. Such a concrete slab is mechanically together with other concrete slabs on a prepared surface to a liquid-tight large-area panel system assembled. After to be described in more detail Connection of neighboring concrete slabs with each other and Closing their joints with a seal is obtained in the Result a liquid tight Large-area panel system that works with heavy-duty vehicles is passable.
Wie Figur 1 zeigt, sind an jeder Seite in den
Betonplatten Kupplungselemente 2,3 eingegossen. Jede
Gruppe von miteinander zusammenwirkenden
Kupplungselementen 2,3 benachbarter Betonplatten setzt
sich aus Ankern 2a,2b,3a,3b aus Flachmaterial und einem
Kupplungsdorn 4 zusammen. Dabei sind wechselweise an
jeder Seite zwei Anker 2a,2b mit Abstand voneinander und
zwei Anker 3a,3b flach aneinanderliegend in der
Betonplatte 1 eingegossen. Bei der benachbarten
Betonplatte sind die Verhältnisse örtlich gerade
umgekehrt.As Figure 1 shows, are on each side in the
Cast in concrete slabs coupling elements 2.3. Each
Group of interacting with each
Jedes Kupplungselement 2,3 umfaßt Anker 2a,2b,3a,3b aus
Flachmaterial, die jeweils an ihrem aus der Seite der
Betonplatte 1 herausragenden Ende eine seitlich offene
Ausnehmung 2a*,2b*,3b* sowie in ihrem eingegossenen
Bereich Bohrungen 2a**,2b**,3b** aufweisen. Durch die
Bohrungen 2a**,2b**,3b** sind Armierungseisen 5,6
gesteckt, wie den Figuren 2 und 3 zu entnehmen ist. Im
verlegten Zustand der Betonplatten, wie in den Figuren 2
und 3 dargestellt ist, fluchten die Ausnehmungen
2a*,2b*,3b* miteinander, so daß der Kupplungsdorn 4
eingetrieben werden kann. Der Kupplungsdorn 4 hat wie die
Ausnehmungen 2a*,2b*,3b* einen prismatischen Querschnitt
und ist wenigstens im vorderen Bereich seines Schaftes 4a
konisch, so daß er leicht unter Aufweiten und
geringfügiges Ausrichten der anderen Kupplungselemente
2a,2b,3a,3b in deren Ausnehmungen eingetrieben werden
kann. Er wird üblicherweise bis zu seinem Kopf 4b
eingetrieben, so daß der hintere Teil des Schaftes 4a mit
konstantem Querschnitt sich vollständig in den
gegebenenfalls leicht aufgeweiteten Ausnehmungen
2a*,2b*,3b* befindet. Sobald die Betonplatte 1 mit ihren
benachbarten Betonplatten an allen Seiten in der
beschriebenen Weise verriegelt ist, dann ist die
Betonplatte in der Flächenebene in allen Richtungen
festgelegt. Eine zusätzliche Festlegung an zwei
benachbarten Seiten in Längsrichtung der Kante kann
dadurch erreicht werden, daß, wie im Ausführungsbeispiel
gezeigt, zwei Anker 2a,2b mit geringfügigem Abstand
voneinander angeordnet sind und zwei flach
aufeinanderliegende Anker 3a,3b der benachbarten
Betonplatte praktisch spielfrei zwischen den beiden
Ankern 2a,2b eingesetzt sind, wie in Figur 4 dargestellt
ist.Each
Sobald alle verlegten Betonplatten miteinander verriegelt
sind, werden die Fugen zwischen den Betonplatten durch
eine Dichtung 7 verschlossen.As soon as all laid concrete slabs are locked together

Die besonderen Vorteile des erfindungsgemäßen
Großflächenplattensystems bestehen in der einfachen
Herstellung der Betonplatten mit den Kupplungselementen
2,3,4 und der Verriegelung der verlegten benachbarten
Betonplatten sowie der hohen Lastaufnahme. Die aus
Flachmaterial bestehenden Anker 2a,2b,3a,3b der
Kupplungselemente 2,3 lassen sich beim Gießen der
Betonplatten durch Eingießen und mittels der
eingesteckten Armierungseisen 5,6 fest in der Betonplatte
verankern. Die Anker 2a,2b,3a,3b sind denkbar einfach
herzustellen, zum Beispiel durch Ausstanzen. Sie sind
robust und lassen sich leicht durch einen Kupplungsdorn 4
miteinander verriegeln. Wegen ihrer flachen Ausbildung
und ihrer vertikalen Ausrichtung wirkt sich ihr hohes
Flachenträgheitsmoment günstig auf die
Lastaufnahmefähigkeit des Großflächenplattensystems aus,
so daß es auch von Schwerlastfahrzeugen befahrbar ist,
ohne daß die Betonplatten an den Fugen einknicken und die
Dichtung in den Fugen durch Überlast zerstört wird.The particular advantages of the invention
Large area plate systems exist in the simple
Production of the concrete slabs with the
Sofern eine einzelne Platte, zum Beispiel wegen einer
Beschädigung, ausgetauscht werden soll, ist dies leicht
möglich. Nach Aufschneiden der allseitigen Dichtung an
der Platte und dem damit verbundenen Freilegen der
Kupplungselemente 2,3,4 brauchen lediglich die
Kupplungsdorne 4 aus den Kupplungselementen 2,3 entfernt
zu werden. Dann kann die Platte senkrecht aus dem
Plattenverband herausgehoben und in gleicher Weise durch
eine neue Platte ersetzt werden.If a single plate, for example because of a
