Definitions

  • the invention relates to a ventilated facade system, which is generally designed for covering outer perimeter walls of buildings and creating a gap between the latter and the panels that form the ventilated facade system, for protection from thermal stresses and noise pollution.
  • This system consists in the provision of one or more counter-walls mounted to the exterior of walls and parallel thereto, and supported by a grid frame, which stands against and is fixed to the surfaces of the walls to be covered.
  • the frame has its own transverse thickness and the outer surface of the latter has typically flat panels mounted thereto, and arranged in orderly rows and columns, in such a number as to entirely cover the surfaces of the walls to be covered.
  • a panel made of an insulating material, whose thickness is smaller than the total thickness of the wall, is usually installed within such thickness, such that an air gap or ventilation chamber is created, to thereby form the ventilated facade system.
  • the thickness of the frame creates a gap between the panels and the covered surfaces of the building, for circulation of air flows, which act as a thermal and acoustic barrier.
  • ventilated facade systems both avoid direct contact between the perimeter walls of buildings and the surrounding environment, thereby protecting the former from excessive cold and heat, and prevent most sound waves from reaching the walls of the building, thereby protecting it from acoustic pollution.
  • the panels that form the counter-walls are designed to be opened and closed as needed whereas, in other arrangements, the panels are fixedly mounted to the support frame and air flows into and out of the gap through special apertures formed at the base and the top of the covering system.
  • the panels that form the outer covering walls are attached to the support frame by means of appropriate fastening hooks, which have the dual purpose of firmly and durably supporting the weight of each panel and of holding the panels firm against the frame.
  • hooks shall also allow quick mounting of panels as well quick replacement thereof in case of damage or wear caused by weather.
  • the hooks that are currently used for fixing and supporting the panels against the frame have a highly sturdy structure and are oversized to prevent any failure that might lead to accidental removal and fall of the panels, which would be a serious hazard for the safety of people passing by near the covered buildings.
  • each hook is composed of a plate that has a quadrangular body, with one edge folded to a V shape, i.e. at an acute angle, relative to the body, thereby forming a projecting lip that is designed to be inserted into a corresponding cavity specially formed in the rear of each panel.
  • the number of hooks and cavities is proportional to the size and weight of each panel, the geometry of the wall to be covered, as well as the value of the external actions that exert stresses on the wall of the building, such as wind pressure, seismic stresses and the like, and the hooks and the cavities are coupled together before mounting each panel to the frame.
  • the folding angle of the edge of each hook is selected for the V profile of the folded edge to be forced into its respective cavity, whereby the folded edge will be pressed into friction-engagement with the cavity for substantially stable coupling between the hook and the cavity.
  • a panel that is ready for mounting shall have hooks with their respective folded edges coupled with the corresponding cavities and the bodies with flat portions projecting out of the edges of the panel.
  • These flat portions have holes for receiving screws and bolts allowing the panel to be fixed to the frame.
  • a first drawback is that the structures of the hooks, and typically their flat portions, are almost entirely exposed to the view of those who look at the curtain walls from the outside, and this affects the exterior appearance of the buildings that are covered with ventilated facade systems.
  • a second drawback is that, due to the oversize of the hooks, the flat portions thereof cannot be overlapped, because this would cause plane misalignment between the panels that form the counter-walls, due to the thickness of the hooks.
  • the positions of the cavities in the rear of the panels shall be established beforehand, to prevent any interference to occur between hooks of contiguous panels.
  • the hooks of contiguous panels shall be placed in misaligned positions, to prevent them from overlapping, and this requires the panels to be formed with hook cavities in different positions from one panel to another.
  • each panel shall be specially formed with hook cavities in particular positions, and not with the same arrangement for each panel, which would certainly be a quicker and more cost-effective solution.
  • a third drawback is that the coupling between the folded edges and the corresponding cavities becomes substantially loose with time and, when wind impinges upon the panels, such loose coupling may generate vibrations in the panels, that might be transferred to the frame and produce a bothering noise, that will be ultimately transferred from the frame to the perimeter wall of the building, thereby not only affecting noise protection, but also creating additional noise.
  • One object of the invention is to improve the prior art.
  • Another object of the invention is to provide a ventilated facade system that can hide from direct view at least most of the structure of the hooks that fix the panels of the counter-walls to the frame.
  • a further object of the invention is to provide a ventilated facade system in which panels may be provided with hook cavities in identical positions in each panel, which will afford quicker and less expensive fabrication of the panels.
  • a further object of the invention is to provide a ventilated facade system that affords easy and quick mounting and removal of each panel.
  • Yet another object of the invention is to provide a ventilated facade system that allows the support hooks to be placed in any desired position, including positions that cause overlapping with other panels, without causing panel misalignment.
  • the invention relates to a ventilated facade system as defined by the features of claim 1.
  • numeral 1 designates each panel that forms a wall of a ventilated facade system of the invention.
  • Each panel 1 is fixed to a support frame 2 which is in turn fixed by brackets 23 to a surface 3 of a perimeter wall 4 of a building to be covered.
  • the panels are mounted to the frame 2 by means of first plate-like support elements 5, second plate-like support elements 6 and third plate-like guide elements 7 for guiding concurrent edges 8 of panels 1.
  • each first plate-like support element consists of a flat plate-like body 9 having a thickness of a few millimeters, and with one edge 10, i.e. the lower edge in the operating position, forming two first cantilever lips 11 extending from the side 10, perpendicular to the plate-like body 9.
  • Through holes 12 are also provided in the plate-like body 9, to be engaged by screws, bolts, rivets and the like (not shown because irrelevant to the invention) for fixing each first support element 5 to the frame 2.
  • a third guide element 7 consists of a plate body 13 having substantially the same thickness as the first plate-like support elements 5 and with second cantilever lips 14 formed therein, extending perpendicular to the plate body 13 and aligned to each other in parallel and perpendicular directions "X" and "Y" by twos.
  • the plate body 13 also has a series of through holes 15 to be engaged by screws, bolts, rivets and the like for fixation thereof to the frame 2.
  • the second plate-like support elements 6 consist of a plate body 16 which is considerably thinner than the first plate-like support elements and the third guide elements, and hence is very thin, having a thickness of the order of a few tenths of a millimeter.
  • the plate body 16 has one edge 17 folded at an acute angle relative thereto, to form a hook, as viewed laterally.
  • Such hook is designed to be engaged in a corresponding cavity 18, as shown in greater detail in Figure 3 , which is formed as an undercut by milling the wall of a panel 1 that will be the rear wall in operation, and is referenced 1A.
  • Apertures 16A are formed in the plate bodies 16 with various orientations, e.g. parallel to the edges, as shown in Figure 7 .
  • fluid fillers 19 such as a polyurethane adhesive
  • the folding angle of the edges 17 is preferably, but not necessarily, more acute than the angle of undercut of the cavities 18, such that they will be mutually coupled by a slight force fit.
  • a safety mesh 20 e.g. made of glass fibers, is bonded to the rear face 1A of each panel 1, and extends between the girders 21 that form the frame 2 without covering the portions of this rear face 1A that contact the girders 21.
  • respective layers 22 of adhesive material e.g. a polyurethane adhesive
  • a polyurethane adhesive are interposed between the girders 21 and the free ends of the rear faces 1A, to reduce or eliminate the panel vibration problems caused by external stresses that might cause the failure of the panel.
  • the second plate-like elements 6 are placed beforehand, on site, on each panel 1, by forcing the folded edges 17 into the respective cavities 18 formed in the rear faces 1A of each panel 1.
  • the second plate-like elements 6 have their respective plate bodies 16 protruding out of the perimeter sides of each panel 1, as shown in Figure 1 .
  • the panel 1 When a panel 1 is completed and the fillers 19 have set, the panel 1 will be mounted to the frame 2 in its expected position and fixed thereto, e.g. by means of screws that extend through the apertures 16A.
  • Both the first plate-like support elements 5 and the third plate-like guide elements 7 are fixed beforehand to the frame 2, such that the former can provide support to the edge that is designed to be the lower edge of each panel 1 when mounted and the latter can ensure proper orientation of the concurrent edges 8 at the vertex thereof during mounting.
  • the panels 1 are supported, both during mounting and in the mounted state, by two cantilever lips 11 which perpendicularly project out of each plate-like body 9, whereas the orientation and the maintenance of proper orientation is obtained by placing the ends of the edges of each panel 1 on a respective second cantilever lip 14, as schematically shown in Figure 1 and in Figure 4 .
  • the number of cavities 18 to be formed on the rear wall 1A of each panel 1 may be calculated between a minimum value and a maximum value, as a function of the surface area and the thickness of the panel.
  • the two parallel lines “R3” and “R4" define the thickness "S" of a panel therebetween and the intersections "P1" and “P2” define on the y axis the possible panel volume values "V3" and "V4", i.e. the minimum and maximum plane dimensions, for the panel to have 4 cavities and, as a result, as many second plate-like support elements 6.
  • the number "N” of cavities 18 may be determined, as exemplarily referenced in the diagram as N4, N6, N8, N10, N12, as well as the number of second plate-like support elements 6 as required for supporting that particular panel 1.
  • the invention has been found to fulfill the intended objects.
