Abstract (en)
The beam (1) has secondary beams whose intermediate fixing unit (3) is fixedly placed on an intermediate section (4) of a central core (2). Sleeves (5, 6) include fixing units (7, 8) of secondary beams mounted on end sections (20a, 20b) of the core to slide on the core toward and away from the intermediate fixing unit. The fixing units extend laterally and longitudinally along the intermediate section and along the sleeves. The intermediate fixing unit is carried by a third sleeve (11). The third sleeve has a cross-section identical to that of the sleeves. An independent claim is also included for a support structure of a formwork of slab.
