Abstract (en)
It is disclosed a flexible, inextensible, tubular body (1) made of a compact or woven material like, for example, paper or raffia, so that said tubular body can be modularly compacted or wound in rolls (2) during storage and transport. When the form work is assembled, cylindrical, rigid rings (3, 3') are coupled to the ends of the tubular body (1) and tightened to the ends of the tubular body (1) so that they remain definitely fixed by means of cramps or any other suitable element (4). Finally, the rings (3, 3') are conveniently separate by means of extensible poles (6) so that the complete tubular body (1) takes a cylindrical form. Thus, a structurally simple and inexpensive form work is obtained, which is easy to assemble, and in which the most expensive parts are recoverable and reusable.
