The invention relates to a structure for the construction 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 characterised in comprising, after deployment and installation, a parallelepiped volume with a rigid front façade (2) and rear façade (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). Each lateral wall is thus composed of four rectangular leaves (20) of the same height and which can be folded by means of an accordion style of folding, characterised in that the distance between the two central axes (6) remains constant and that the structure comprises two fixing or anchoring means (12 and 13) on each lateral wall (4, 5), positioned on top of the structure and symmetrically with relation to the central axis (6). The method for folding or unfolding is characterised in that a lifting beam is used to raise the structure which folds or unfolds under the influence of the weight thereof, due to the force exerted by the weight on cables (27, 28) fixed between the lifting beam and the structure.

L~invention concerne une structure pour la construction de bâtiments pliables et dépliables par exemple mais non limitativement de logements pour chevaux, du type comportant des cadres en profilés soudés habillés de panneaux ou bâches et pouvant comporter des portes, fenêtre, aération, l~ensemble étant recouvert par un toit, structure caractérisée en ce qu~elle constitue lorsqu~elle est déployée et installée un volume parallélépipédique avec une façade avant (2) et une façade arrière (3) rigides et deux parois latérales pliables, chaque paroi latérale (4, 5) comportant des moyens d~articulation (19) sur un axe d~articulation vertical central (6) et sur deux axes d~articulation verticaux secondaires (7 et 8) prévus de part et d~autre de l~axe central (6), chaque paroi latérale étant ainsi composée de quatre volets (20) rectangulaire de même hauteur et aptes à être pliés selon un pliage dit «en accordéon», caractérisé en ce que la distance entre les deux axes centraux (6) reste constante et caractérisé en ce que, la structure comporte sur chaque paroi latérale (4, 5) deux moyens de fixation ou d~accrochage (12 et 13) positionnés sur le dessus de la structure et symétriquement par rapport à l~axe central (6). Le procédé de pliage ou de dépliage est caractérisé en ce qu~on utilise un palonnier pour soulever la structure qui se déplie ou se plie sous l~effet de son poids, grâce à la traction exercée par le poids sur des câbles (27, 28) accrochés entre le palonnier et la structure.
