Abstract

In order to produce a prestressed bridge (21) made of reinforced concrete with the static system of a continuous support or frame with at least two fields, longitudinal supports (11) are installed using a crane, a shifting device or the cyclical shifting method; prestressing members (36) are installed and partially prestressed in the cavity (17) formed by the wall panels (12), the base panels (13) and the top panels (14) in the longitudinal supports (11); deck panel elements (2) are placed on the longitudinal supports (11); a reinforcement is laid on the deck panel elements (2) and the top concrete (9) is applied to the deck panel elements (2), wherein a bearing beam (4) is installed in at least one pillar axis (6) on the bridge bearings (29) arranged in the at least one pillar axis (6) before the longitudinal supports (11) are installed.
