Frame for a monolithic prefabricated opening ensuring a perfect rigidity while being light enough to be handled manually. It comprises the rest 1, the recessed jamb posts 4 and 5 and the one-way form 11 of the lintel. The said one-way form having the shape of a gutter comprising internally, at its base, the ribs 14 and 15 provided with cradles 16 and 17 intended for receiving the lintel frame irons and to position them with respect to each other and with respect to the lower surface of the said gutter so that the concrete of the cast lintel perfectly envelopes the said irons naturally positioned by the said cradles 16 and 17 in order to ensure the best resistance of the lintel to flexion. The invention may be used for constructing any opening in a building, picture window, window or door. <IMAGE>
