    The ventilated facade without frame with intermediate folded sheet forming ribs, is characterized by the incorporation of an intermediate folded sheet, which acts as a resistant element and serves as a support for the elements that constitute the facade. The sheet is folded forming ribs both inside and outside, following appropriate modulations to be able to fix the finishing material of the exterior and the transmission of the loads (own weight and horizontal actions) to the structure of the building by means of specific fasteners located in the edge of the slab. The solution improves the existing solutions because: a) the folded sheet eliminates the need to incorporate a frame that holds the facade, b) allows to fix the rest of the elements that constitute the facade, c) allows to establish a modulation to the interior equal or different outside and d) improves behavior and increases resilience during and after an extreme event.

    VENTILATED FACADE WITHOUT FRAME WITH INTERMEDIATE FOLDED SHEET
    FORMING NERVADURES
    Ventilated facade without frame with intermediate folded sheet forming vertical ribs on both sides and located in the intermediate part, which replaces the need to incorporate a frame of discrete elements and improves the overall behavior of the enclosure against actions produced by extreme events.
    SECTOR OF THE TECHNIQUE
    The invention is part of the technical construction sector, specifically in the construction of ventilated facade enclosure elements.
    STATE OF THE TECHNIQUE
    Ventilated facade solutions are characterized by the inclusion of a ventilated chamber between the exterior finishing material of the facade and the rest of the layers that form the contemporary facades, among which the thermal insulation material and the interior finishing material stand out . These materials have a superficial development and the ventilated chamber prevents the contact of the finishing material, which is exposed to the climatic agents of the rest of the facade materials. In order to place the outer material separated from the rest of the layers of the facade it is necessary to incorporate some element or substructure of support with mechanical capacity that allows to hold the own weight of the finishing material and transfer the gravitational and horizontal loads to the main structure of the building . Conventional solutions of ventilated façade can be of two types: those that have a support wall on which vertical or horizontal linear elements are fixed or those that only use a frame of discrete elements fixed to the edge of the slabs or floor slabs , constituted at least by a family of vertical elements or uprights that are fixed by point anchors with the possibility of three-dimensional adjustment. These uprights are normally complemented by a second family of horizontal or cross-sectional linear elements that reduce the support distance of the pieces that usually constitute the exterior finishing material of the facade. Rack solutions have a lower weight of their own and allow to increase the speed of execution, since they usually include dry joints. In the latter case, there are solutions in the market that include a sheet

    continuous or a board located in an intermediate position and fixed to the frame, to improve the strength and stiffness of the facade.
    There are solutions in which the folded sheet metal is used as a material for the manufacture of discrete linear elements of the frame, either in the form of T-section studs (EP 1 533 431 A1) or in U or O (ES 2 451 166 A1), or of a plurality of plates or trays with a U-section fixed directly to the floor slab (EP 1712 694 B1). In the case of the ES 2 451 166 A1 patent, the Q-section elements that constitute the frame are complemented by a grooved sheet that is fixed to the sheet metal profiles in I1 on which an inside (trasdos) is applied thermal insulating material by projection.
    All these solutions differ from the present invention since they are configured by a series of discrete linear elements, in most cases forming a frame, and not a continuous sheet, and its geometry only responds to the modulation required to transfer the loads of the facade to the structure of the building, being necessary a second modulation to be able to locate the finished material of the ventilated facade. In addition, the present invention surpasses the existing ones constituted by a frame in which it improves the resilience against mechanical actions produced by extreme events by having a mechanical continuity throughout its surface since the thermal insulation material is located both inside the sheet as outside, maintaining at least part of its thermal capacity even in the case of the loss of the external finishing material, which would render the insulation of this side of the facade useless.
    EXPLANATION OF THE INVENTION
    The object of the invention is a new ventilated facade solution that incorporates a continuous folded sheet in an intermediate position that acts as a supporting element of the facade by means of the folding of ribs both towards the inside and towards the outside of the facade, in addition to guaranteeing mechanical continuity given its vertical development that protects the inside of the facade, especially in case of extreme weather events, such as strong winds or earthquakes.

    The ribs of the sheet, which are produced by vertical folding of a continuous sheet, are made on both sides of the sheet, following a modulation that can be the same on both sides or different. The ribs located on the inner face of the facade increase the rigidity of the facade and allow the loads applied on the facade, gravitational and horizontal, to be transferred to the structure by means of specific fixations to the slab edges. For its part, the ribs located outside allow the placement of the exterior finishing material of the facade by means of specific fixing elements or including a series of horizontal linear elements fixed by mechanical means to the external ribs, forming a ventilated chamber.
    In addition, the grooves that occur between the nerves both inside and outside are used to locate an insulating material on both sides of the sheet, it is advisable that the insulation inside has a vapor barrier in hot face to reduce the risk of interstitial condensations. The mismatch of the ribs inside and outside prevents the formation of thermal bridges. On the other hand, the joints between the sheets can be made in the formation of the ribs by means of the overlap of two or more sheets that can be attached by the side of the ribs to the points of attachment with the forged by mechanical fixations.
    The main advantage of this new solution is that it does not require a frame of uprights and crossbars, since the folded sheet forming ribs on both sides of the sheet gives the facade a mechanical rigidity that gives the system the ability to transfer loads mechanics without the need for a specific structure. The possibility of folding the sheet with the required dimensions, allows solutions with different modulations since the ribs can be produced according to different modulations, even in the same facade cloth, and with different sections and height of the ribs.
    Regarding the procedure for the execution of the façade, the new solution facilitates the staking of the façade with respect to the structure of the building, since it allows the regulation at the fixing points both in height and in the direction perpendicular to the facade by means of mechanical joints arranged on the side of the rib. Therefore, the fixing system only requires adjustment in the horizontal direction contained in the plane of

    facade, instead of the three-dimensional regulation required in conventional systems with frame.
    Another advantage of the new ventilated façade solution is the increase in the rigidity of the assembly that produces the inclusion of the folded sheet, increasing the mechanical resistance of the assembly against horizontal actions, especially those produced by extreme events, such as hurricane winds, earthquakes or otherwise, increasing post-event resilience since the sheet will protect the inside of the facade, maintaining the post-event functionality of the facade. Likewise, the continuity of the sheet will mean that the failure of a specific fixation does not imply the collapse of the facade due to loss of mechanical capacity.
    DESCRIPTION OF THE DRAWINGS
    Figure 1 represents the horizontal section of the folded sheet with ribs on both sides of it.
    Figure 2 represents a horizontal section of the overlap joint in the rib of two folded sheets with the fastening element of the facade to the structure.
    Figure 3 shows a section or vertical section of the ventilated facade solution.
    Figure 4 shows in axonometry the constituent parts of the new ventilated facade solution.
    MODE OF REALIZATION
    One way to build the new facade solution begins with the staking of the fixing elements (4) of the folded sheet (1), according to the pre-established modulation in the design of each concrete facade. The sheet (1) is folded by conventional mechanical means by vertical folding, constituting the inner and outer ribs (2), which can form an angle to the facade plane between 45 and 90 degrees. The modulation of the ribs (2) ranges between 40 and 160 cm, while the heights of the ribs (2) vary between 4 and 30 cm in the case of the interiors and between 4 and 20 cm in the case of the outside The sheets are fixed by mechanical means (3) to the specific connecting elements (4) and to the floor slabs
    (5) by mechanical or welded joint (6). Overlapping joints of adjacent sheets and those of consecutive heights are made at the fixing points, where the manufacturing and execution tolerances of the structure can be absorbed. In the grooves of the plates between the ribs on both sides of the sheet, a thermal insulation material (7) is placed on a plate or blanket or by projection, with a minimum section of 2 cm and a maximum section of 12 cm on each side of the sheet. The exterior finishing material (8) is fixed by means of point anchors (9) on the ridges of the outer ribs, creating a ventilated chamber with a section between 4 and 20 cm thick. The interior finish of the façade (10) can be fixed to a frame of shaped sheet profiles 10, joined by mechanical fixings to the lower and upper face of the slabs of each floor or by a family of crossbars or point fixings to the folded sheet intermediate. The facade gaps would be made by cutting the sheet and the formation of ribs that would constitute the sides of the hole, complemented by crossbars attached to these ribs delimiting the lower and upper part of the hole. The carpentry of the hole is attached directly to the frame consisting of ribs and crossbars by mechanical fixings.
