mittels Querkraftübertragungsbugel (QT-Bügel) *..·,; by means of transverse force transmission bracket (QT bracket) *..·,;

Überschreiten die Zugspannungen in der Betonbodenplatte die Zugfestigkeiten beim linearen Schwindverhalten, - entsteht ein Riß.If the tensile stresses in the concrete floor slab exceed the tensile strengths during linear shrinkage, a crack will occur.

Unkontrollierte Risse müssen oft saniert werden. Uncontrolled cracks often need to be repaired.

Kontrollierte Risse werden über das Einschneiden (Sollbruchfugen, Scheinfugen) mit der Diamantscheibe gesteuert.Controlled cracks are controlled by cutting (predetermined breaking joints, dummy joints) with the diamond disk.

Nimmt eine "Scheinfuge" die ihr zugedachte Funktion war, ist sie eine "Echte Fuge."If a "dummy joint" fulfills the function intended for it, it is a "real joint."

Die Praxis zeigt, daß Querkraftübertragungen durch die Restverzahnung von ca. 2/3 der Bodenplattendicke, insbesondere bei Wechsellasten, - hervorgerufen durch Gabelstapler - bei Hallennutzung, nicht mehr aufgenommen werden.Practice shows that transverse force transmissions are no longer absorbed by the remaining interlocking of approx. 2/3 of the floor slab thickness, especially in the case of alternating loads - caused by forklifts - when used in a hall.

Die Plattenenden federn beim Überfahren nach.The ends of the plates give way when driven over.

Durch die Verstufung erhält die Staplerwelle einen plötzlichen Schlag, welche die allg. Lebensdauer solcher Wellen und Lauflager nachhaltig verringert.Due to the staggering, the forklift shaft receives a sudden impact, which permanently reduces the general service life of such shafts and bearings.

Wie einsetzbar?How can it be used?

Diese QT-Bügel liegen im unteren Drittel der Bodenplatte, im Abstand von ca, 15 cm und werden vor, während oder nach dem, Betoneinbau, eingebaut. Der Betoneinbau erfolgt direkt vom Fahrmischer.These QT brackets are located in the lower third of the base plate, at a distance of approx. 15 cm and are installed before, during or after the concrete is placed. The concrete is placed directly from the truck mixer.

Farbmarkierungen auf der Folie sind eine zusätzliche Orientierungshilfe.Color markings on the film provide additional orientation aid.

Der QT-Bügel ist stabil, legt sich ohne Zerstörung auf die Folie auf und verbiegt sich nicht unter Personenbelastung.The QT bracket is stable, rests on the film without being damaged and does not bend under the weight of a person.

1. gut verdichtetes Planum, entsprechend der Normen und zugeordneten Regelwerken, welches ·..·.£ das Befahren mit Fahrmischern ermöglicht,1. well-compacted subgrade, in accordance with the standards and associated regulations, which allows truck mixers to be driven on,

2. lichte Torhöhe von £ 3,80 m.2. Clear gate height of £ 3.80 m.

Vorteile:Advantages:

Keine Baustahlmatten,No steel mesh,

keine Abstandshalter für die 1. und 2. Bewehrunglage, no spacers for the 1st and 2nd reinforcement layer,

keine zusätzlichen Verlegungskosten für die Bewehrung,no additional installation costs for the reinforcement,

sofortiges Entleeren des Fahrmischers nach Ankunft auf der Baustelle,Immediate emptying of the truck mixer upon arrival at the construction site,

kein Abladen von Bewehrungsmatten mittels Kran, Handentladung der QT-Bügel gut möglich,no unloading of reinforcement mats by crane, manual unloading of the QT stirrups is easily possible,

leichter Transport auf der Baustelle, Gewicht eines QT-Bügelkorbes von ca. 2 m Länge, = ca. 22 kg.easy transport on the construction site, weight of a QT ironing basket of approx. 2 m length, = approx. 22 kg.

Der Betoneinbau kann direkt über die bewegliche Schüttvorrichtung vom Fahrmischer erfolgen. The concrete can be placed directly using the mobile dumping device on the truck mixer.

Bei evtl. Falschlage des QT-Bügels ist der Bügelkorb mühelos aus dem Frischtbeton zu ziehen und kann an der richtigen Stelle wieder eingedrückt werden.If the QT bracket is in the wrong position, the bracket basket can be easily pulled out of the fresh concrete and pushed back in at the correct position.
