PRECONTRATED CONCRETE BEAM CARRIED OUT BY EMBITION OF TWO LONGERONS AND METHOD OF ATTRACTING TWO BEAMS

摘要

Beam (1) of high performance fiber-reinforced concrete, characterized in that it comprises a first spar (2.1) comprising at least one core (3.1), having a flange (4.1) along one of the longitudinal edges of the core and, along its opposite edge, a tongue (5.1) nested in a groove (5.2) of complementary shape belonging to a second spar (2.2) having, opposite the groove, a support sole (4.2), at least one of the longitudinal members comprising a longitudinal stress cable (9) embedded in the concrete parallel to the neutral longitudinal axis (10) of the beam.
