- the object of the invention is to simplify the sealing of the breakthroughs acting as thrust anchors in the trough-shaped reinforcement with respect to the liquid mineral filler and at the same time to significantly increase the strength and bending stiffness of the finished composite panel and thus its load-bearing capacity.
- the object is achieved in that the leakage of the mineral filler, for example anhydrite-preventing layer consists of a liquid or plastic applied and then cured surface protection and / or finishing agent, which as a closed skin with a correspondingly small clear diameter closes in a trough-shaped reinforcement in a number of openings (punches) made similar to a grater.
- This method of sealing the openings (punctures) requires a surface protection or finishing agent with a corresponding viscosity and a clear diameter of the openings (punches) of only a few millimeters.
- the basis of the invention is two new findings, the combination of which results in a surprising rationalization in production and at the same time an extremely significant increase in the load-bearing capacity.
- the first new finding is that the magnitude of the thrust that is transmitted by the "punches" from the tub floor to the filled pressure-resistant filler depends on the sum of all surfaces that protrude from the tub bottom into the pressure-resistant filler. So the greater the sum of these edge-side surfaces of the punches, the greater the transmitted thrust before the filling material tears off the tub floor. A very large number of small punches can thus transmit a significantly higher thrust than a small number of large punches, while on the other hand the weakening of the floor and thus the reduction in tensile force in the floor does not increase to the same extent.
- the second finding is that small openings (punctures) can be closed efficiently by a protective layer that serves to protect against corrosion or to improve the surface of the tub material.
- the invention therefore consists in the combination of the two new findings.
- the tub bottom is not provided with a relatively small number of large openings (punches) as in the prior art, but rather with a number of openings with a small clear diameter which is several times as large, and then a skin is applied liquid or plastically and this skin is left harden before the mineral filler, e.g. Anhydrite, is introduced. This prevents the liquid filled curable mineral filler from leaking through the openings (punctures).

- the required composite effect between the hardened filler 12 and the trough-shaped reinforcement 11 is achieved by means of numerous openings 13 (punctures) which have frayed edges 14 which protrude inwards. This through Fractures 13 are generated by means of pointed mandrels to be driven into the steel sheet from the outside.
- the height of these edges 14 is approximately 5 mm and the smallest clear diameter b 1 of the openings 13 is approximately 8 mm.
- the openings 13 with the inwardly projecting edges 14 can also be referred to as thrust anchors.
- the finished composite panel 10 has a square floor plan and is supported with its corners on footrests, which in turn are placed on the respective floor of the building (not shown).
- the composite panel 10A according to the invention shown in FIG. 2 has the same two main components as the composite panel 10 of FIG. 1, namely the trough-shaped outer reinforcement 11 made of, for example, sheet steel and the mineral filler 12, for example anhydrite.
- the filler 12 is also poured into the trough-shaped reinforcement 11 in liquid form and is then allowed to harden therein.
- openings 13 punctures
- frayed edges 14 projecting inwards.
- the liquid mineral filler 12 runs out through these openings 13 here through to the outside Prevents the trough-shaped reinforcement 11 from applying liquid, hardening surface protection or finishing agent which, after hardening, forms a skin 19 on the entire outside of the trough-shaped reinforcement (bottom and side walls), which closes the openings 13 to the outside.
- a surface protection or finishing agent for example, a quick-drying, correspondingly viscous synthetic resin varnish can be used, which is applied to the outside of the trough-shaped reinforcement 11 is sprayed on.
- This synthetic resin varnish can contain fiber pieces, for example glass fiber pieces, as filler in order to securely close the openings 13 and to seal them outwards, as shown in FIG. 4.
- liquid mineral filler 12 is introduced into the trough-shaped reinforcement 11 only after the surface protection and / or finishing agent has hardened or the protective and sealing skin 19 has been formed.
- the setting time of the lacquer which consists of a quick-drying quality, can be accelerated by adding heat.

Abstract
Description
Die Erfindung bezieht sich auf eine freitragende Verbundplatte für Doppelböden, Decken oder dergleichen mit einer wannenförmigen äußeren Bewehrung aus Blech, vorzugsweise Stahlblech und einem im fließfähigen Zustand in diese Bewehrung einzubringenden, aushärtbaren, mineralischen Füllstoff, z.B. Anhydrit, wobei die Verbundwirkung zwischen dem ausgehärteten Füllstoff und der wannenförmigen Bewehrung durch in deren Boden- und Seitenwänden vorgesehenen Durchbrüche (Punzen) mit nach innen hervorstehenden, ausgefransten Rändern erzeugt wird, und wobei ferner die wannenförmige Bewehrung an ihrer Außenseite mit einer das Auslaufen des Füllstoffes durch die Durchbrüche verhindernden Schicht überzogen ist.The invention relates to a self-supporting composite panel for raised floors, ceilings or the like with a trough-shaped outer reinforcement made of sheet metal, preferably sheet steel and a curable, mineral filler to be introduced into this reinforcement in the flowable state, e.g. Anhydrite, the composite effect between the hardened filler and the trough-shaped reinforcement being produced by openings (punctures) provided in the bottom and side walls thereof with inwardly protruding, frayed edges, and furthermore the trough-shaped reinforcement on the outside with a leakage of the filler is covered by the layer preventing breakthroughs.
Bei der Herstellung einer durch die DE-PS 2 004 101 bekannt ge-wordenen Verbundplatte der obigen Bauart wird das Auslaufen des im flüssigen Zustand in die wannenförmige Bewehrung eingebrachten mineralischen Füllstoffes, z.B. Anhydrit durch die trichterähnlichen Durchbrüche in der Blechwanne zur Zeit dadurch verhindert, daß man vor dem Einfüllvorgang die Außenseite des Wannenbodens und der Wannenseitenwände mit Aluminiumfolie beklebt, welche die Wannendurchbrüche nach außen abschließt. Diese Art der Abdichtung der Durchbrüche in der wannenförmigen Bewehrung ist jedoch arbeitsintensiv und daher unwirtschaftlich. Andererseits werden diese trichterähnlichen Durchbrüche in der wannenförmigen Bewehrung zur Schaffung der erforderlichen Verbundwirkung zwischen Bewehrung und ausgehärtetem Füllstoff benötigt. Man hat nämlich herausgefunden, daß die Tragkraft der Verbundplatte im wesentlichen durch den Verbund zwischen dem ausgehärteten mineralischen Füllstoff und den als Schubanker wirkenden trichterähnlichen Durchbrüchen in der wannenförmigen Bewehrung bestimmt wird.In the production of a known g from DE-PS 2004101 e-wordenen composite panel of the above type the leakage of the introduced in the liquid state into the trough-shaped reinforcing mineral filler is, for example, anhydrite by the funnel-like openings in the sheet metal trough currently prevented by that before the filling process, the outside of the tub bottom and the tub side walls are covered with aluminum foil, which closes the tub openings to the outside. However, this type of sealing the openings in the trough-shaped reinforcement is labor-intensive and therefore uneconomical. On the other hand, these funnel-like openings in the trough-shaped reinforcement are required to create the required bonding effect between the reinforcement and the hardened filler. One has namely found that the load-bearing capacity of the composite panel is essentially determined by the bond between the hardened mineral filler and the funnel-like openings in the trough-shaped reinforcement that act as thrust anchors.
Die Erfindung dient der Aufgabe, die Abdichtung der als Schubanker wirkenden Durchbrüche in der wannenförmigen Bewehrung gegenüber dem flüssigen mineralischen Füllstoff zu vereinfachen und zugleich die Festigkeit und Biegesteifigkeit der fertigen Verbundplatte und damit deren Tragfähigkeit wesentlich zu erhöhen.The object of the invention is to simplify the sealing of the breakthroughs acting as thrust anchors in the trough-shaped reinforcement with respect to the liquid mineral filler and at the same time to significantly increase the strength and bending stiffness of the finished composite panel and thus its load-bearing capacity.
Gemäß der Erfindung wird die gestellte Aufgabe dadurch gelöst, daß die das Auslaufen des mineralischen Füllstoffes, z.B. Anhydrit verhindernde Schicht aus einem flüssig oder plastisch aufgetragenen und danach ausgehärteten Oberflächenschutz-und/oder -veredelungsmittel besteht, welches als geschlossene Haut die mit entsprechend kleinem lichten Durchmesser in einer einem Reibeisen ähnlichen Vielzahl hergestellten Durchbrüche (Punzen) in der wannenförmigen Bewehrung verschließt. Diese Methode zur Abdichtung der Durchbrüche (Punzen) setzt ein Oberflächenschutz-oder veredelungsmittel mit entsprechender Viskosität sowie einen lichten Durchmesser der Durchbrüche (Punzen) von nur einigen wenigen Millimetern voraus. Da bei Verwendung von zum Beispiel einfachem Stahlblech zur Herstellung der wannenförmigen Bewehrung ohnehin ein Oberflächenschutz gegen Korrosion vorzusehen ist, kann erfindungsgemäß das hierfür erforderliche Mittel nunmehr zugleich für den Verschluß der erwähnten Durchbrüche in der wannenförmigen Bewehrung benutzt werden. Versuche haben gezeigt, daß selbst bei beträchtlicher Reduzierung der lichten Durchmesser der Durchbrüche im Vergleich zum Stand der Technik keine verringerte Tragkraft der Verbundplatte in Kauf genommen werden muß, sondern daß durch Vervielfachung der Zahl der Durchbrüche im Vergleich zum Stand der Technik sogar eine merkliche Erhöhung der Festigkeit, Biegesteifigkeit und damit Tragkraft der Verbundplatte erreicht werden kann.According to the invention the object is achieved in that the leakage of the mineral filler, for example anhydrite-preventing layer consists of a liquid or plastic applied and then cured surface protection and / or finishing agent, which as a closed skin with a correspondingly small clear diameter closes in a trough-shaped reinforcement in a number of openings (punches) made similar to a grater. This method of sealing the openings (punctures) requires a surface protection or finishing agent with a corresponding viscosity and a clear diameter of the openings (punches) of only a few millimeters. Since a surface protection against corrosion is to be provided anyway when using, for example, simple steel sheet for producing the trough-shaped reinforcement, the means required for this can now be used according to the invention for the closure of the openings mentioned in the trough-shaped reinforcement. Experiments have shown that even with a considerable reduction in the clear diameter of the openings compared to the prior art, no reduced load-bearing capacity of the composite plate has to be accepted, but that by multiplying the number of openings compared to the prior art, there is even a noticeable increase in the Firm speed, bending stiffness and thus load capacity of the composite panel can be achieved.
Mit anderen Worten, Grundlage der Erfindung sind zwei neue Erkenntnisse, durch deren Kombination eine überraschende Rationalisierung in der Fertigung und zugleich eine äußerst bedeutsame Erhöhung der Tragfähigkeit erzielt wird. Die erste neue Erkenntnis besteht darin, daß die Größe der Schubkraft, die durch die "Punzen" vom Wannenboden auf den eingefüllten druckfesten Füllstoff übertragen wird, abhängig ist von der Summe aller Oberflächen, die aus dem Wannenboden heraus in den druckfesten Füllstoff hineinragen. Je größer also die Summe dieser Rand-Seitenflächen der Punzen ist, desto größer wird auch die übertragende Schubkraft, bevor das Füllmaterial vom Wannenboden abreißt. Man kann also durch eine sehr große Anzahl kleiner Punzen eine wesentlich höhere Schubkraft übertragen als durch eine geringe Anzahl großer Punzen, während andererseits die Schwächung des Bodens und damit die Minderung der Zugkraft im Boden nicht im gleichen Maße steigt.In other words, the basis of the invention is two new findings, the combination of which results in a surprising rationalization in production and at the same time an extremely significant increase in the load-bearing capacity. The first new finding is that the magnitude of the thrust that is transmitted by the "punches" from the tub floor to the filled pressure-resistant filler depends on the sum of all surfaces that protrude from the tub bottom into the pressure-resistant filler. So the greater the sum of these edge-side surfaces of the punches, the greater the transmitted thrust before the filling material tears off the tub floor. A very large number of small punches can thus transmit a significantly higher thrust than a small number of large punches, while on the other hand the weakening of the floor and thus the reduction in tensile force in the floor does not increase to the same extent.
Die zweite Erkenntnis besteht darin, daß man kleine Durchbrüche (Punzen) rationell durch eine Schutzschicht verschließen kann, die dem Korrosionsschutz bzw. der Oberflächenveredelung des Wannenmaterials dient. Die Erfindung besteht daher in der Kombination der beiden neuen Erkenntnisse. So wird der Wannenboden nicht wie beim Stand der Technik mit einer relativ kleinen Zahl großer Durchbrüche (Punzen), sondern mit einer mehrfach so großen Anzahl von Durchbrüchen mit kleinem lichten Durchmesser versehen, und dann wird eine Haut flüssig oder plastisch aufgetragen und man läßt diese Haut aushärten bevor der mineralische Füllstoff, z.B. Anhydrit, eingebracht wird. Dadurch wird der flüssig eingefüllte aushärtbare minerale Füllstoff behindert durch die Durchbrüche (Punzen) auszulaufen.The second finding is that small openings (punctures) can be closed efficiently by a protective layer that serves to protect against corrosion or to improve the surface of the tub material. The invention therefore consists in the combination of the two new findings. Thus, the tub bottom is not provided with a relatively small number of large openings (punches) as in the prior art, but rather with a number of openings with a small clear diameter which is several times as large, and then a skin is applied liquid or plastically and this skin is left harden before the mineral filler, e.g. Anhydrite, is introduced. This prevents the liquid filled curable mineral filler from leaking through the openings (punctures).
Eine Ausgestaltung der Erfindung sieht vor, daß die die Durchbrüche verschließende Haut durch einen schnell trocknenden Lack gebildet ist, der einen Füllstoff aus z.B. Faserstückchen enthält. Der Füllstoff setzt sich beim Auftragen bzw.Aufspritzen des Kunstharzlackes auf die Außenseite der wannenförmigen Bewehrung vorteilhaft in den trichterförmigen Durchbrüchen fest und begünstigt dadurch an der Haut die Ausbildung von "Verschlußstopfen" in den Durchbrüchen.One embodiment of the invention provides that the skin that closes the openings is formed by a quick-drying lacquer that contains a filler made of e.g. Contains pieces of fiber. When the synthetic resin varnish is applied or sprayed onto the outside of the trough-shaped reinforcement, the filler advantageously settles in the funnel-shaped openings and thereby favors the formation of "sealing plugs" on the skin in the openings.
Nach einer anderen Ausgestaltung der Erfindung kann die die Durchbrüche verschließende Haut eine Zinkhaut sein. Diese Zinkhaut kann z.B. durch Aufspritzen einer Zinkstaubfarbe oder im Zuge einer Feuerverzinkung der wannenförmigen Bewehrung aus Stahlblech ausgebildet werden.According to another embodiment of the invention, the skin that closes the openings can be a zinc skin. This zinc skin can e.g. by spraying on a zinc dust paint or by hot-dip galvanizing the trough-shaped reinforcement from sheet steel.

Die in Fig. 1 gezeigte Verbundplatte 10 bekannter Bauart weist eine wannenförmige äußere Bewehrung 11 aus z.B. Stahlblech sowie einen aushärtbaren mineralischen Füllstoff 12, z.B. Anhydrit auf, der im flüssigen Zustand in die wannenförmige Bewehrung 11 eingebracht wird. Die erforderliche Verbundwirkung zwischen dem ausgehärteten Füllstoff 12 und der wannenförmigen Bewehrung 11 wird mittels zahlreicher Durchbrüche 13 (Punzen) erreicht, welche nach innen hervorstehende, ausgefranste Ränder 14 aufweisen. Diese Durchbrüche 13 werden mittels in das Stahlblech von außen einzutreibender spitzer Dorne erzeugt. Die Höhe dieser Ränder 14 beträgt etwa 5 mm und der kleinste lichte Durchmesser b 1der Durchbrüche 13 ca .8 mm. Die Durchbrüche 13 mit den nach innen ragenden Rändern 14 kann man auch als Schubanker bezeichnen. Um beim Einfüllen des flüssigen mineralischen Füllstoffes 12 in die wannenförmige Bewehrung 11 ein Auslaufen desselben durch diese Durchbrüche 13 hindurch zu vermeiden, werden bisher auf die Außenseite des Bodens 15 und der Seitenwände 16 der wannenförmigen Bewehrung 11 Aluminiumfolien 17 bzw. 18 aufgeklebt, welche die Durchbrüche 13 nach außen verschließen. Die fertige Verbundplatte 10 hat einen quadratischenGrundriß und wird mit ihren Ecken auf Fußstützen aufgelagert, die ihrerseits auf dem jeweiligen Gebäudeboden aufgestellt sind (nicht gezeigt).1 has a trough-shaped
Die in Fig. 2 gezeigte erfindungsgemäße Verbundplatte 10A weist die zwei gleichen Hauptbestandteile wie die Verbundplatte 10 der Fig. 1 auf, nämlich die wannenförmige äußere Bewehrung 11 aus z.B. Stahlblech sowie den mineralischen Füllstoff 12, z.B. Anhydrit. Der Füllstoff 12 wird gleichfalls flüssig in die wannenförmige Bewehrung 11 eingefüllt und man läßt ihn dann darin aushärten. Zur Erzielung der Verbundwirkung zwischen dem ausgehärteten Füllstoff 12 und der wannenförmigen Bewehrung 11 dienen ebenfalls Durchbrüche 13 (Punzen) mit nach innen hervorstehenden, ausgefransten Rändern 14. Das Auslaufen des flüssigen mineralischen Füllstoffes 12 durch diese Durchbrüche 13 hindurch wird hier jedoch durch ein auf die Außenseite der wannenförmigen Bewehrung 11 vor dem Einfüllvorgang flüssig aufgetragenes, aushärtendes Oberflächenschutz-oder -veredelungsmittel verhindert, das nach dem Aushärten auf der gesamten Außenseite der wannenförmigen Bewehrung (Boden und Seitenwände) eine Haut 19 bildet, welche die Durchbrüche 13 nach außen verschließt. Als Oberflächenschutz- oder-veredelungsmittel kann z.B. ein schnell trocknender entsprechend viskoser Kunstharzlack verwendet werden, der auf die Außenseite der wannenförmigen Bewehrung 11 aufgespritzt wird. Dieser Kunstharzlack kann Faserstückchen, z.B. Glasfaserstückchen als Füllstoff enthalten, um die Durchbrüche 13 sicher zu verschließen und nach außen abzudichten, wie in Fig. 4 gezeigt ist. Es versteht sich, daß erst nach dem Aushärten des Oberflächenschutz- und/oder -veredelungsmittels bzw. Ausbildung der Schutz- und Abdichtungshaut 19 der flüssige mineralische Füllstoff 12 in die wannenförmige Bewehrung 11 eingebracht wird. Die Abbindezeit des aus einer schnell trocknenden Qualität bestehenden Lackes kann durch Wärmezufuhr noch beschleunigt werden.The composite panel 10A according to the invention shown in FIG. 2 has the same two main components as the
Damit sich über den Durchbrüchen 13 zuverlässig eine geschlossene Haut 19 (Fig. 2) ausbilden kann, beträgt deren kleinster lichter Durchmesser b2 nur einen Bruchteil z.B. 3 mm des kleinsten lichten Durchmessers b1 der Ausführung nach Fig. 1. Im Vergleich zur Konstruktion nach Fig. 1 ist ferner die Zahl der Durchbrüche 13 mehrfach oder vielfach erhöht, z.B. etwa um das Sechsfache im Bodenbereich und um etwa das Dreifache im Seitenwandbereich der wannenförmigen Bewehrung 11. Dadurch wird die Tragfähigkeit der erfindungsgemäßen Verbundplatte 10A gegenüber der bekannten Ausführung sogar erheblich größer, weil die Höhe des nach innen ragenden Randes 14 der Durchbrüche 13 bei der Verbundplatte der Fig. 2 nur geringfügig kleiner als jene bei der bekannten Verbundplatte nach Fig.1 ist, während andererseits die Summe aller Seitenflächen der Durchbrüche (Punzen) die Schubkraft zwischen Wannenboden und Füllstoff übertragen,wesentlich vergrößert ist.So that a closed skin 19 (FIG. 2) can reliably form over the
