A structure that can be folded and unfolded to construct buildings, for example, horse stables, includes frames made from welded profiles and covered with panels having doors, windows or ventilators, covered by a roof. After deployment and installation, the structure forms a parallelepipedal volume with rigid front and rear façades and two folding lateral walls. Each of the lateral walls has a central axis, and joints receiving four rectangular leaves which can be folded accordion-style. The distance between the two central axes remains constant and the structure has two anchoring points on each lateral wall which are positioned on top of the structure and symmetrically relative to the central axis. A lifting beam is used to raise the structure, which folds or unfolds under the influence of the weight of the structure due to forces exerted on cables fixed between the lifting beam and the structure.

The invention claimed is: 1. A structure that can be folded and unfolded to construct a building, including horse stables, having frames made from welded sections and covered with materials capable of receiving mechanical structures including doors, windows and ventilators, and capable of being covered by a roof, wherein the structure has a weight and comprises: a rigid front wall, a rigid rear wall and two folding lateral walls connecting the front wall and the rear wall to form a parallelepipedal volume after deployment and installation of the structure; wherein each of the lateral walls includes a plurality of joints located on a central vertical joint axis and on two secondary vertical joint axes provided on either side of the central joint axis, and four rectangular leaves having the same height and which can be folded accordion-style; wherein the distance between the central joint axis associated with each of the lateral walls remains constant; and wherein the structure includes structure attachment points which support the weight of the structure, wherein two of the structure attachment points are located on each of the lateral walls, and wherein the two structure attachment points are positioned on top portions of the structure at locations which are symmetrical relative to the central joint axis; in combination with a beam coupled with the structure attachment points on the lateral walls, for automatically folding and unfolding the structure responsive to the weight of the structure. 2. The structure of claim 1 which further includes at least one intermediate partition which can be folded accordion-style. 3. The structure of claim 1 wherein the frames further include welded bars for receiving the mechanical structures. 4. The structure of claim 1 wherein the covering materials are attached to the frames to enclose the structure. 5. The structure of claim 4 wherein the covering materials are sheets of material. 6. The structure of claim 4 wherein the covering materials are lightweight rigid panels. 7. The structure of claim 1 wherein the structure attachment points are coupled with two of the leaves adjacent to and on opposing sides of the central joint axis. 8. The structure of claim 1 which further includes a rigid central frame separating the central joint axis associated with each of the lateral walls, for maintaining the distance between the central joint axis associated with each of the lateral walls constant. 9. The structure of claim 1 wherein the beam further includes a pair of beam attachment points spaced from ends of the beam and connected to the nearest adjacent structure attachment points for automatically folding the structure. 10. The structure of claim 9 wherein a pair of connections attach the beam attachment points and the structure attachment points, and wherein the connections are crossed at the beam attachment points. 11. The structure of claim 9 wherein the beam further includes a secondary beam perpendicular to the beam and having secondary beam attachment points located at ends of the secondary beam, and wherein the secondary beam attachment points are connected to the nearest adjacent structure attachment points for automatically unfolding the structure. 12. A method for folding and unfolding the structure of claim 1, comprising the steps of: coupling the beam with the structure attachment points on the lateral walls; and lifting the beam and the structure, and automatically folding and unfolding the structure responsive to the weight of the structure. 13. The method of claim 12 wherein the folding and unfolding is responsive to tensile forces exerted by the weight of the structure on connections attached between the beam and the structure. 14. The method of claim 13 wherein the beam further includes a pair of beam attachment points spaced from ends of the beam, and wherein the method further includes the step of attaching the beam attachment points to the nearest adjacent structure attachment points for automatically folding the structure. 15. The method of claim 14 which further includes the step of crossing the connections attaching the beam attachment points and the structure attachment points. 16. The method of claim 13 wherein the beam further includes a secondary beam perpendicular to the beam and having secondary beam attachment points located at ends of the secondary beam, and wherein the method further includes the step of attaching the secondary beam attachment points to the nearest adjacent structure attachment points for automatically unfolding the structure.
