Definitions

• the present invention relates to a modular compactable prefabricated structure.
• the field of reference is the prefabricated building sector, in particular the one of folding structures composed of a set of hinged elements that can be compacted in minimum volume configuration during transportation and developed in full volume configuration during use.
• module refers to a folding structure suitable for creating a prefabricated structure.
• Prefabricated buildings can be divided into three macro-categories, the first one being the provision of a set of walls suitable for being connected being transported to the place where the prefabricated structure is to be realized; in this first type, the connection means need to be transported to the place of installation, where the operators will connect the walls in vertical or horizontal position according to the layout.
• a second type provides for installing modular housing units that are produced in the factory and are not compactable.
• the transportation of said non-compactable modular housing units is extremely complicated, requires special permissions and involves high transportation costs.
• a third type uses a folding/unfolding technique for the realization of the prefabricated structure.
• the third type comprises a plurality of hinged walls that can be moved between a folded position, in minimum volume configuration, to an unfolded position, in full volume configuration.
• folding modules usually comprise three hinged walls, namely a bottom and two lateral walls, which define a housing unit with prismatic shape and substantially triangular section, once they are unfolded.
• the modules are completely produced at the manufacturing company, and they are simply moved from the minimum volume configuration to the full volume configuration in the place of installation.
• DE1171329B discloses a collapsible container comprising a bottom, a front folding wall and a back folding wall that are hinged to the bottom.
• Said container has an upper wall hinged to the front wall and to the back wall and two lateral walls.
• Each lateral wall has a fixed part and a mobile part.
• the mobile part of the lateral wall is composed of a single panel.
• an intermediate element that connects the two lateral walls is not provided.
• Such a container is not modular and cannot be used to realize a prefabricated structure.
• US3849952A and FR1484761 A disclose a capsule-unit housing comprising multiple folding modules. Each module comprises a bottom and a front folding wall and a back folding wall that are hinged to the bottom. Therefore, a prefabricated structure obtained by placing two modules side by side is not provided with a continuous space from the front of the first module to the back of the second module. Said documents do not disclose lateral walls that are integral with the housing unit. Said modules are cumbersome and cannot be transported by means of road transportation because the bottom connected to the front wall and the back wall is excessively long and does not fit in a means of road transportation.
• the purpose of the present invention is to overcome the drawbacks of the prior art by disclosing a modular compactable prefabricated structure that is extremely rapid to install and logistically effective.
• An additional purpose of the present invention is to disclose a modular compactable prefabricated structure that is inexpensive and easy to make.
• a further purpose of the present invention is to disclose a modular compactable prefabricated structure that is suitably configured not to have any shape constraint, so that it can have various configurations in terms of size and shape along the three dimensions in order to comply with the national and international technical standards.

• each module (M6, M6’, M7 M7’) of the prefabricated structure of the sixth and seventh embodiment also comprises fastening means (not shown in the appended figures) that are disposed between the first panel (52a) and the second panel (52b) and are suitable for being fastened by hoisting machines in order to lift the two panels (52a and 52b).
• the modules (M6, M6’, M7, M7’) of the prefabricated structures of the sixth and seventh embodiment differ in the position of the mobile hinging means (53).
• the mobile hinging means (53) are disposed in the external sides of the two panels (52a, 52b), whereas in the modules (M7, M7’) of the prefabricated structure (P7) of the seventh embodiment shown in Fig. 7, the mobile hinging means (53) are disposed in the internal sides of the two panels (52a, 52b).
• the right-hand lateral wall comprises the folding mobile portion
• the left-hand lateral wall only comprises the fixed portion
• the position of the right-hand lateral wall and of the left-hand lateral wall can be inverted.
• the prefabricated structure (P1 , P2, P3, P4, P5, P6, P7) also comprises foundation screws with connection plates that are fixed by means of fixing means (such as for example screws and the like) to the bottoms (1 , 1 ’) of the front and back module.
• fixing means such as for example screws and the like
• the foundation screws are firstly screwed onto the ground and then the bottom is fixed to the connection plates of the foundation screws.
• one or more intermediate modules can be disposed between the front module and the back module in such a way to extend the prefabricated structure along an orthogonal direction relative to the front and back wall.
• the module may be devoid of the horizontal upper wall (2), thus defining a module with only one level defined by the bottom (1 ).
• the roof will be defined by the mobile portions (52, 52’) and/or by the intermediate element (6).
• Doors, windows, balconies, terraces and the like can be mounted on the modular compactable prefabricated structure.
• insulating panels, solar panels, electrical installations, water systems, gutters, seals to guarantee the tightness between two adjacent structural elements, etc. can be installed on the modular compactable prefabricated structure.
