A fast unfolding two-layer temporary flooring structure consisting of preferably rigid plates ( 1 to 6 ), made of a suitable material. The plates ( 1 to 6 ) are arranged mutually parallel and cascade-linked by an articulated linking element (B) so that between two consecutive plates, the element (B) is linked to an edge of the other plates, and also preferably in a central zone of the other plate, the elements defining hinge lines between parallel planes with longitudinal or transverse axis of the plates.
