The invention relates to prefabricated deformable and foldable construction elements. A construction element 2 according to the invention is made up of bored bars 5 which are intercrossing and are articulated in pairs via their ends 7 and via articulations 8 situated at their intersection points in such a way that they form a sequence of deformable quadrilaterals, and which comprise in addition right-angled attachment brackets 9 situated at the four free ends, and, if appropriate, intermediate brackets 10 allowing the element to be fixed, for example, on two parallel frames or rails 1, 3 in order to form a truss girder. An application is the rapid construction of temporary supports on building sites. <IMAGE>
