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 the feed funnels 14 into a molding chamber 3 A with only relatively low transverse forces, in which the presses are located for the screw 3, since there is no transverse reinforcement such as stirrups. The named individual parts would take the resulting from the transverse forces are supported by a frame 18, which is present 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 screw press 3 has a cylindrical end of a device for producing prestressed concrete attachment, which produces a cylindrical recess in the hollow beam of the type mentioned at the outset. The molding chamber 3 A is after 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 which carries a vibrator 20 which can be provided on the reinforcement. Frame 18 is supported with springs.

Each sliding guide 31 has two 3 A facing and on each side by U-profiles31 ^ 4 and 31B, the mutually inverted legs located in each side wall 19 compress one of the width of the driver slot 24 in the mold chamber 3 A - 5 32 have a corresponding distance from each other. Data concrete should be inserted. For this purpose, are equipped with a uniform feeding of the strap secured in accordance with Figure 4 Zapfen25 where the Fcrmkammer is, the driver 32 is formed so as to so-3 A facing edge of a plate 26 ^ accommodated, probably the upper and the lower bracket legs which grasps the bracket 23 when it is pushed into the mold 23 '.

The two parts which consist of pre-tensioned steel cables 35. The sliding guides 26 A are dimensioned by vertical transverse brackets 23 so that they are held at a distance from one another after the single girder 26 B and the pre-stressed ones are attached to the frame 18 in the compacted concrete. Steel cables 35 overlap on the outside, the stirrups 23 being seated with their open ends of legs 36 directed downwards over a considerable part of their length, according to FIG. 4 on lateral sliding overlaps. If the length of the overpasses 31 on which they are fed to the plates 26 is lapped, they are pushed in from two sides. By means of a driver bracket 23, the supply can have the effect of closed brackets.
