Die Erfindung betrifft eine Vorrichtung zum Her- y. Herstellen von in die Pfeiler eingespannten Überstellen einer mehrfeldrigen Brücke aus Stahlbeton bauteilen sich nur symmetrisch verformt. Diese Aufoder Spannbeton, mit der die Überbaufelder jeweils gäbe wird dadurch gelöst, daß der Vorbauträger von einem Pfeiler aus symmetrisch nach beiden Seiten jeweils auf dem Pfeiler, von dem aus vorgebaut wird, vorgebaut werden und die einen oberhalb oder unter- S oder auf einem mit diesem Pfeiler biegesteif verhalb der Überbauteile angeordneten Vorbauträger bundenen Überbauabschnitt auf mindestens zwei in aufweist. Längsrichtung der Brücke im Abstand voneinanderThe invention relates to a device for Her- y. Manufacture of transfers clamped into the pillars a multi-span bridge made of reinforced concrete are only symmetrically deformed. This Aufoder Prestressed concrete, with which the superstructure fields would exist, is solved by the fact that the front girder from one pillar symmetrically to both sides on the pillar from which the construction is being carried out, be built in front and the one above or below, S or on one with this pillar, is rigid of the superstructure parts arranged front girders bound superstructure section on at least two in having. Longitudinal direction of the bridge at a distance from each other
Es ist bereits bekannt, den Überbau einer mehr- angeordneten Stützmitteln gelagert ist, von denen aus feldrigen Brücke in etwa feldlangen Abschnitten von er in Längsrichtung der Brücke nach beiden Seiten einem frei tragenden Schalungsträger aus herzustellen, io frei auskragt.It is already known, the superstructure of a multi-arranged support means is mounted from which field bridge in approximately field-length sections of it in the longitudinal direction of the bridge on both sides to produce a cantilever formwork beam, io freely cantilevered.

After completion of the superstructure of the individual superstructure sections on both sides of the construction section, the formwork girder is always the same size into the next 15 of the respective pillar and is advanced through a free field. simply shortening the stages of each one
