Ventilated facade system

Abstract

A ventilated facade system includes a support frame fixed to a surface of a wall to be covered; a plurality of covering panels, each having an outer face and an opposite rear face and being fixed to the support frame in a selected arrangement; a plurality of fixing units that fix the panels to the frame and include a first plate-shaped support element having a flat body, which is fixed to the frame and has an outwardly-projecting and shear-resistant first support bracket lip; a second plate-shaped support element having a plate body with one edge folded to form an acute angle to be inserted into a corresponding cavity formed in the rear face, the support element being resistant to tensile stress and having a portion designed to be fixed to the frame; and a third flat element guiding concurrent edges of contiguous panels, which is fixed to the frame.

The invention claimed is: 
     
         1 . A ventilated facade system comprising:
 a support frame affixed to a surface of a wall to be covered;   a plurality of covering panels, each of which has an outer face and an opposing rear face and is fixed to the support frame according to a selected arrangement; and   a plurality of fixing units of said panels to said frame,   wherein said fixing units comprise:   at least one first laminar support element having a plate-shaped body fixed on said frame and shaping at least a first support bracket lip that projects toward an outside and is shear-resistant;   at least a second laminar support element having a plate-shaped body and one folded edge, said edge being folded according to an acute angle and adapted to be inserted into a correspondent cavity obtained in said rear face, said second laminar support element being pull-resistant and having a portion designed to be fixed on said frame; and   at least one third flat guide-maintenance element of concurrent vertexes of contiguous panels, fixed on said frame.   
     
     
         2 . The system as claimed in  claim 1 , wherein said at least first support element, second support element, and third guide-maintenance element are fitted on said frame according to a selectable number and gaps by a calculation system. 
     
     
         3 . The system as claimed in  claim 2 , wherein said calculation system comprises a function equation Y=f(X). 
     
     
         4 . The system as claimed in  claim 3 , wherein said function equation f(X) is (ax+b) or (ax−b). 
     
     
         5 . The system as claimed in  claim 1 , wherein said at least first support element has a transversal L-shaped cross-section. 
     
     
         6 . The system as claimed in  claim 1 , wherein said at least second support element comprises passage openings for fixing members to said frame, which can be superimposed to and conjugated in a correspondent way with passage openings of an additional second support element in a superimposed configuration. 
     
     
         7 . The system as claimed in  claim 1 , wherein an anti-vibration element is interposed between said folded edge and said cavity. 
     
     
         8 . The system as claimed in  claim 7 , wherein said anti-vibration element comprises a filling of a polyurethane adhesive. 
     
     
         9 . The system as claimed in  claim 1 , wherein said at least one third guide-maintenance element comprises a flat body, from which couples of second support bracket lips extend that are reciprocally aligned along aligning directions. 
     
     
         10 . The system as claimed in  claim 9 , wherein said aligning directions are reciprocally perpendicular. 
     
     
         11 . The system as claimed in  claim 1 , wherein said covering panels are equipped with a net fixed on said rear face. 
     
     
         12 . The system as claimed in  claim 1 , wherein said fixing units further comprise adhesive elements fitted between said frame and said rear face.
