This formwork consists of a number of metal frames 2, 3 having a generally rectangular shape comprising ties 4 ensuring their stiffness, the various frames being installed parallel to each other, offset axially and joined to each other in a rigid manner by ties 5, each element having a length corresponding substantially to the length of the standard sheetings 6 and each frame being made from a member having a section allowing the engagement of the upper horizontal members between two transverse members 9 of a sheeting and their fixing to these members, one of the two formwork elements belonging to two juxtaposed elements and being equipped, at its upper part, with a metal sheet 18 forming the crown which, projecting in the direction of the other element, is intended to overlap the adjacent edges of the upper sheetings of the two elements and to fill the gap between these sheetings. <IMAGE>
