VENTILATED FACADE WITHOUT A FRAME AND WITH AN INTERMEDIATE FOLDED SHEET FORMING RIBS
WO18055225
The ventilated facade, without a frame and with an intermediate folded sheet forming ribs, is characterised by including an intermediate folded sheet, which acts as a reinforcing element and functions to support the elements forming the facade. The sheet is folded forming ribs both on the inside and on the outside, following modulations suitable for being able to secure the finishing material of the exterior and for the transmission of loads (its own weight and horizontal actions) to the structure of the building via intermittent securing elements located on the slab edge. This solution improves upon existing solutions because: a) the folded sheet eliminates the need to include a frame to support the facade; b) same permits the securing of the rest of the elements forming the facade; c) same permits the establishment of a modulation on the inside that is the same as or different from the outside; and d) same improves the behaviour and increases the resilience during and after an extreme event.
The invention does not require a structural frame, since the folded sheet forming ribs on both sides of the sheet endows the facade with mechanical stiffness giving the system the ability to transfer mechanical loads without the need of a specific structure. Regarding the construction procedure of the facade, it facilitates the redesign of the facade regarding the structure of the building, since it allows the adjustment at the fixing points both in height and in the direction perpendicular to the facade by means of mechanical joints arranged in the side of the rib. The fixing system only requires adjusters in the horizontal direction contained in the facade plane, rather than the threedimensional adjusting systems required in conventional frame ventilated facades. Technical difficulty and reasonable implementation costs. The other facade elements can be fixed directly to the folded sheet. It allows to establish a modulation to the interior equal or different from the one of the exterior. Improves the overall performance of the facade and increases resilience during and after an extreme event linked to the effect of water or external horizontal forces, such as those produced by strong winds, hurricanes, earthquakes, etc.
