Description

Bisher bekannte Massivdecken brauchen zur Erreichung der Wärme- und Schallisolation nachträglich eine teuere Fußbodenauflage mit entsprechenden Eigenschaften. Außerdem wird die Druckzone bei Betonbalken meist erst auf der Baustelle durch einen besonderen Arbeitsgang gegossen. Beide Nachteile werden durch die Erfindung vermieden.Previously known solid ceilings need to achieve the heat and Sound insulation retrofitted an expensive floor covering with corresponding properties. In addition, the pressure zone on concrete beams is usually only created by a device on the construction site cast in a special process. Both disadvantages are avoided by the invention.

'Die Betonbalken werden aus einem leichten, wärmehaltigen und schalldämmenden Leichtbetön hergestellt, sie bieten deshalb im Gegensatz zu den bisher üblichen Kiesbetonbalken keine Kältebrücke. Bei dieser leichten Gestaltung des Balkens muß statisch ohne Haftfestigkeit zwischen Stahl und Leichtbeton gerechnet werden. Gemäß der Erfindung wird daher als Bewehrung ein Stahlgitterträger verwendet. Zur Herstellung des Trägers eignen sich am besten Flachstäbe, die infolge der Einbettung nicht ausknicken können, anderseits jedoch die wirtschaftliche Widerstandsschweißung zulassen.'The concrete beams are made of a light, warm and sound-insulating Made of lightweight concrete, they therefore offer in contrast to the previously usual Gravel concrete beams no thermal bridges. With this light design of the beam must statically without adhesive strength between steel and lightweight concrete. According to According to the invention, a steel lattice girder is therefore used as reinforcement. For the production of the beam are best flat bars that do not buckle as a result of the embedding can, on the other hand, however, allow economical resistance welding.

Die Verwendung von Leichtbeton für Deckenbalken bringt eine zu geringe Seitenfestigkeit derselben, die nur durch Einlegen einer seitlichen Drahtbewehrung verhindert werden kann. Der Fertigungsprozeß der Balken würde aber bei faserhaltigem Material durch die Drähte sehr behindert werden. Die Erfindung sieht deshalb ein nachträgliches Einlegen der Drähte durch Offenlassen zweier Längsvertiefungen vor, die später mit Beton ausgefüllt werden.The use of lightweight concrete for ceiling beams is too low Lateral strength of the same, which can only be achieved by inserting a lateral wire reinforcement can be prevented. The manufacturing process of the beams would, however, with fibrous Material can be very obstructed by the wires. The invention therefore provides subsequent insertion of the wires by leaving two longitudinal indentations open, which will later be filled with concrete.

Die Erfindung ermöglicht die Verwendung eines billigen, feuersicheren, wärmehaltigen und nagelbaren Leichtbetons und damit einen guten Schutz gegen Brandausbreitung. Außerdem ist durch die Nagelbarkeit der Balken und der Deckensteine ein direktes Aufbringen des Fußbodens ohne Zwischenhölzer oder einer anderen Gehschicht ohne Zwischenisolierung erreicht.The invention enables the use of an inexpensive, fireproof, Heat-containing lightweight concrete that can be nailed to and therefore good protection against the spread of fire. In addition, the nailability of the beams and the ceiling stones is a direct one Application of the floor without intermediate timbers or another layer of walking without Intermediate isolation achieved.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Der Fertigbalken besteht aus dem mit Leichtbeton a ummantelten Gitterträger b, c, dessen Stäbe bei d miteinander verschweißt sind. Ober- und Untergurt sowie die Füllstäbe bestehen aus Flachstahl. Zur Erhöhung der Seitensteifigkeit ist die aus Rundstahl bestehende Bewehrung f eingelegt. Die Bewehrungsdrähte f sind in Längsrillen e eingelegt, die nach Erhärtung des Leichtbetons geschlossen werden.The drawing shows an embodiment of the subject matter of the invention shown. The prefabricated beam consists of the lattice girder covered with lightweight concrete a b, c, the bars of which are welded together at d. Upper and lower belt as well the cross bars are made of flat steel. To increase the lateral stiffness, the Reinforcement made of round steel is inserted. The reinforcing wires f are in longitudinal grooves e are inserted, which are closed after the lightweight concrete has hardened.
