Abstract: 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.

Abstract: The invention relates to a structure for the constructions of folding and unfolding buildings, for example, horse stables but not limited thereto, of the type comprising frames made from welded profiles and covered with panels or sheets which may comprise doors, windows or ventilators, the whole assembly being covered by a roof. The structure is characterized in comprising, after deployment and installation, a parallepiped volume with a rigid front facade (2) and rear facade (3) and two folding lateral walls. Each lateral wall (4, 5) comprises jointing means (19) on one central vertical joint axis (6) and on two secondary vertical joint axes (7 and 8) provided to either side of the central axis (6).
