Abstract: A transportable structure to form houses and the like, for immediate use in case of calamities and for other uses, comprises a supporting framework made up of closed longitudinal frames, floor platform, roof covering and head walls, all of which delimiting a useful volume, and mobile panels that are able to form additional side rooms. The mobile panels are finished with protruding elements, which form, at least in part, cylindrical surfaces slidingly cooperating to form articulations. Angle bars are provided at the ends of the structural sections to make up the seats for pins that are able to prevent the cooperating cylindrical surfaces from incidentally moving away from each other. Further angle bars perimetrically complete the panels while seals mounted on the sections coact with the sections being coupled at the articulations to ensure sealing.
