benen Grundrissformen durch beliebige Träger- anordnung weitgehend entsprochen werden ; gleichzeitig ist die Möglichkeit gegeben, mit gleich bewehrten Trägern verschiedenen ge- gebenen Belastungen unter Einhaltung der zu- lässigen Stahlspannungen durch Veränderung der
Verlagsweite gerecht zu werden.
Die Schalbleche berühren die Kanten der
Oberflanschen der Fertigbetonträger j. Hiedurch bleiben einerseits die in Blechformen hergestellten schalsauberen Fertigträger auch nach Platten- betonierung an den Seitenflächen schalungsrein.
Anderseits sind die Bleche dadurch, dass nur an den oberen Blechteilen Neubeton aufgebracht wird, leicht entfernbar und haften nicht an den seitlichen Trägerflanken. Durch Verstärkung der Unterflanschdicke c kann hiebei bei gleichen Blechformaten an Deckenkonstruktionshöhe und somit durch die Vergrösserung der Nutzhöhe an Deckentragfähigkeit gewonnen werden (s. Fig. 2).
Die Putzträgeraufhängung erfolgt durch senkrecht in vorgesehene Löcher e eingeführte Rundeisenstäbe k, die am oberen Ende in dem nachträglich aufgebrachten Plattenbeton h ihre Verankerung finden.
Der Plattenbeton h wird nach Verlegen der Träger a und der Verteilungseisen e an der Baustelle erstellt. Der Verbund zwischen Träger und Platte wird durch ausragende Bügelschlaufenf sichergestellt.
PATENTANSPRÜCHE : 1. Verfahren zur Herstellung einer Fertigbetonträgerdecke mit auf der Baustelle auf Blechschalungen betonierter Platte, dadurch gekennzeichnet, dass Ast-Mollin-Bleche oder einhüftige Schalbleche auf fabriksmässig erzeugten I-Fertigstahlbetonträgern derart eingebracht werden, dass sich die Unterkanten der Schalbleche in ihrer gesamten Länge stets nur am Unterflansch des Trägers aufstützen.

plan shapes can be largely met by any carrier arrangement; At the same time, there is the possibility of using equally reinforced girders to carry out various given loads while maintaining the permissible steel stresses by changing the
To meet publisher-wide.
The shuttering sheets touch the edges of the
Top flanges of precast concrete beams j. As a result, on the one hand, the prefabricated girders produced in sheet metal molds remain clean on the side surfaces even after slab concreting.
On the other hand, because new concrete is only applied to the upper sheet metal parts, the sheets are easily removable and do not adhere to the lateral girder flanks. By reinforcing the lower flange thickness c, the ceiling construction height can be achieved with the same sheet metal formats and thus the ceiling load-bearing capacity can be achieved by increasing the usable height (see Fig. 2).
The plaster base is suspended by round iron rods k inserted vertically into holes e provided, which are anchored at the upper end in the subsequently applied slab concrete h.
The slab concrete h is created at the construction site after the girders a and the distribution bars e have been laid. The connection between the carrier and the plate is ensured by protruding bow loops
PATENT CLAIMS: 1. A method for the production of a precast concrete support ceiling with a plate concreted on sheet metal formwork on the construction site, characterized in that Ast-Mollin sheets or single-hip formwork sheets are placed on prefabricated reinforced concrete beams produced in the factory in such a way that the lower edges of the formwork sheets extend over their entire length always support only on the lower flange of the beam.
