Description
Mit einer bekannten Vorrichtung dieser Art lassen 50 Elektromotor 9 über ein Zahnradgetriebe erfolgt,
sich Spannbetonhohlbalken herstellen, die zwar eine Zum Zuführen des Betons dient ein Aufgabevorgespannte Längsbewehrung, jedoch keine Quer- trichter 14. Der Beton wird durch unter dem Aufbewehrung
aufweisen. Diese Hohlbalken können so- gabetrichter 14 befindliche Förderschnecken 15 in

Pre-stressed longitudinal reinforcement is used to feed the concrete, but no transverse funnels 14. The concrete will have through under the storage. These hollow beams can take up feed funnels 15 located in the feed funnel 14 into a mold chamber 3 A with only relatively low forces, in which the presses are located. since there is no transverse reinforcement, such as a bracket, at the screw 3. The individual parts mentioned would take the resulting from the transverse forces are supported by a frame 18, which is provided with four tensile stresses and the tensile stress wheels 22 move on rails of a concreting bed can therefore be absorbed by the concrete itself.

The tensile strength of concrete but is loading the molding chamber 3 A is the cross section of kanntlich low. 60 to be produced reinforced concrete hollow beam 34 adapted. The invention is therefore based on the object. The screw press 3 has a cylindrical end, a device for producing prestressed concrete attachment, which has a cylindrical opening. ung in the hollow beam of the type mentioned at the outset, heistellt concrete beams. The molding chamber 3 λ is after the fact that the prestressed concrete to be produced with it is open at the bottom, has side walls 19 and an upper hollow beam during production with a transverse cover plate that carries a vibrator 20 that can be provided on the reinforcement. Frame 18 is supported with springs.
