Abstract
A junction between successive flat pre-fabricated elements which comprises an elastic transverse insert (9), an approaching mechanism (10) in the form of tie beams (23) and tensioning mechanisms (19). The flat pre-fabricated elements (2) to be assembled each have a transverse channel (3) adapted so as to receive the insert along the end transverse edges (4, 5) thereof, which must face each other after assembly on the ground, and conduits (7) of the tie beams. Each pre-fabricated element is successively arranged, one after the other, and the transverse insert is introduced into the transverse housing (6) formed by transverse channels facing each other. The tie beams are introduced into the conduits, the ends thereof projecting outside the pre-fabricated elements. The tie beams are then tensioned by a tensioning mechanism, at each of the ends thereof, in order to immobilize the flat pre-fabricated elements and thereby connected by the tie beams.
