Description

Bewehrungszulage zum Verstärken von fertigen Betondecken Die Erfindung betrifft eine Bewehrungszulage zum Verstärken von fertigen Betondecken. Diese Bewehrungszulage ist dadurch gekennzeichnet, daß sie aus Stahllamellen besteht, die an der Unterseite und an der Oberseite der Betondecke flach anliegen und paarweise durch lotrechte Schraubenbolzen, insbesondere durch hochfeste Schraubenbolzen, verbunden sind.Reinforcement allowance for reinforcing finished concrete ceilings The invention relates to a reinforcement allowance for reinforcing finished concrete ceilings. This reinforcement allowance is characterized in that it consists of steel lamellas attached to the underside and lie flat against the top of the concrete ceiling and in pairs through perpendicular Screw bolts, in particular by high-strength screw bolts, are connected.

Bekannt ist die Anwendung von Lamellen, die durch eingeschweißte Bolzen miteinander verbunden sind. Die Schweißverbindung muß vor der Ausmauerung oder dem Ausgießen mit Beton hergestellt werden, so daß diese Ausführung nicht nachträglich hergestellt werden kann.The use of lamellae, which are welded in by bolts, is known are connected to each other. The welded connection must be in front of the brick lining or the Pouring can be made with concrete, so this execution is not an afterthought can be produced.

Weiter sind Träger bekannt, die aus Hohlsteinen hergestellt sind und durch Lamellen auf der Unterseite sowie durch Schraubenbolzen zusammengehalten werden. Bei anderen bekannten Verbundträeern unter Verwendung von Steinen sind die Lamellen nur auf der Unterseite angeordnet. Auch diese Bewehrungen werden nicht nachträglich angebracht, sondern bereits bei der Herstellung der Träger vorgesehen.Carriers are also known which are made from hollow stones and are held together by slats on the underside and screw bolts. In other known composite beams using stones, the lamellas are arranged only on the underside. These reinforcements are also not retrospectively attached, but already provided during the manufacture of the carrier.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, die Tragkraft einer fertigen Betondecke zu erhöhen, z. B. wenn die Güte des verwendeten Betons für die vorgesehene Belastung nicht ausreicht.The invention is based on the object, the load capacity to increase a finished concrete ceiling, e.g. B. if the quality of the concrete used is not sufficient for the intended load.

Es genügt, verhältnismäßig dünne Lamellen oben und unten an die Decke mittels insbesondere hochfester Schraubenbolzen anzupressen. Die Schraubenbolzen drücken die Lamellen so fest an die Decke, daß die Reibungskräfte eine volle Übertragung der Schubkräfte zwischen Lamellen und Decke bewirken. Infolgedessen sind bei der Berechnung der Tragkraft der Decke die beiden Lamellen und die Decke statisch als ein Baukörper anzusehen. Daraus ergibt sich ein Vielfaches der Tragkraft gegenüber der unverstärkten Decke.It is sufficient to attach relatively thin slats to the ceiling at the top and bottom to be pressed using particularly high-strength screw bolts. The screw bolts press the slats so tightly against the ceiling that the frictional forces have a full transmission the shear forces between the slats and the ceiling. As a result, the Calculation of the load-bearing capacity of the ceiling, the two slats and the ceiling statically as to look at a building. This results in a multiple of the load capacity compared to the unreinforced ceiling.

In der Zeichnung sind Ausführungsbeispiele für die verstärkte Betondecke nach der Erfindung wiedergegeben. Es zeigt F i g. 1 einen Schnitt durch die Decke mit einfacher Verschraubung der Lamellen, F i g. 2 einen gleichen Schnitt mit paarweise eingesetzten Schraubenbolzen, F i g. 3 einen Schnitt mit Senkkopfschraube, F i g. 4 einen Längsschnitt durch die Decke mit Seitenansicht der Lamellen.In the drawing are exemplary embodiments for the reinforced concrete ceiling reproduced according to the invention. It shows F i g. 1 a section through the ceiling with a simple screw connection of the lamellas, FIG. 2 an identical section with in pairs inserted screw bolts, F i g. 3 shows a section with a countersunk head screw, FIG. 4 shows a longitudinal section through the ceiling with a side view of the slats.

Auf die Decke 1 ist oben die Lamelle 2 und auf der Unterseite die Lamelle 3 angelegt. Beide Lamellen 2 und 3 und die dazwischenliegende Decke 1 sind durchbohrt. Durch die Bohrung sind hochfeste Schraubenbolzen 4 gezogen und durch eine Mutter 5 befestigt. The lamella 2 is placed on top of the ceiling 1 and the lamella 3 is placed on the underside. Both slats 2 and 3 and the ceiling 1 in between are pierced. High-strength screw bolts 4 are pulled through the bore and fastened by a nut 5.

Die untere Lamelle mit dem Schraubenkopf wird von dem Deckenputz überstrichen. Bei geringer Putzstärke werden Schraubenbolzen mit Senkkopf verwendet. Die obere Lamelle mit der Mutter wird von dem Fußboden überdeckt und liegt innerhalb der, Unterlage aus Glaswolle.The lower lamella with the screw head is painted over by the plaster of the ceiling. Screw bolts with countersunk heads are used for thin plaster. The upper The lamella with the nut is covered by the floor and lies within the, Glass wool underlay.
