<p>The invention is directed to a prefabricated stair formwork structure (1) for making a stair flight, comprising: a first space (A) for containing a concrete cast defined by two longitudinal beam elements (11, 12), arranged parallel to one another, and two transversal beam elements (13,14), also arranged parallel to one another and each coupled with both said longitudinal beam elements (11, 12) at their respective ends; a plurality of shaped elements (15) each defining a second containment space (S) for a concrete cast of corresponding steps, said shaped elements (15) being fixed in succession above said at least two longitudinal beam elements (11, 12); an element (16) for closing the bottom of the formwork structure (1), fixed to said longitudinal and/or transversal beam elements on the opposite side with respect to said shaped elements (15); and a reinforcement structure (C) of the concrete housed in said first containment space (A). The invention is also directed to a prefabricated formwork structure for making a stair landing, comprising: two longitudinal beam elements and two transversal beam elements coupled with both of said longitudinal beam elements to define a containment space for a concrete cast; an element for closing the bottom of the formwork structure, fixed to said longitudinal and/or transversal beam elements; and a reinforcement structure for the concrete housed in said containment space.</p> |
