(57) Prefabricated floor element (1) having an elongated shape wherein a longitudinal direction (X), a transversal direction (Y), a height direction (Z), two end faces (11) which delimitate the element (1) in the longitudinal direction (X), two lateral faces (12) which delimitate the element (1) in the transversal direction (Y), a lower face (13) and an upper planar face (14) that delimitate the element (1) in the height direction (Z) are defined, which comprises transversal con­tinuous upper grooves (15) on the upper planar face (14) or lateral grooves (26) on the lateral faces (24), the lateral grooves (26) extending from the lower tab (TS) to the upper planar face (24). The invention also relates to a structure comprising such prefabricated floor element (1) and further comprising a linear supporting element (LS) which supports one end of the prefabricated floor element (1) such that in the linear supporting element (LS) a supporting surface (51) is defined and a moment resisting system (MS) arranged on the linear supporting element (LS) and facing an end face (11) of the prefabricated floor element (1) and an upper concrete layer (LC) poured on top of the element (1) or in the shear key (SK) defined between two adjacent floor elements. The invention also relates to an installation for manufacturing the floor elements (1, 2).
