Abstract (en)
[origin: WO2020254941A1] The invention concerns a mechanical connection system (1) for connecting a concrete slab (D) to a steel beam (P) to which at least one dowel-type connector (C) is attached. The system comprises, for each connector (C), a frustoconical metal nut (2) having a threaded through-hole (22) into which the connector (C) is screwed, a frustoconical metal sleeve (3) assembled to the nut (2) by conical connection and, for each recess (D1) in the slab (D), a metal cage (4) intended to be assembled in contact with the recess (D1). Sealing concrete (B) fills the recess (D1), such that the slab (D) is secured to the beam (P) by keying by the sealing concrete (B) and the connection system (1). The invention also concerns a composite floor in which at least one concrete slab (D) is secured to at least one steel beam (P) by means of this connection system (1).
