Definitions
- the present invention relates to a cladding structure of a wall using panels or slabs, such as mineral slabs of ceramic, hard stone, marble, granite and the like, in particular for the realisation of ventilated facades.
- a ventilated facade is taken to mean a cladding of a vertical wall, for example in brick, generally achieved with panels mounted at a certain distance from such wall, so as to create an air space between the wall and the cladding.
- the space between the cladding and the wall is designed in such a way that the air present in it can flow by means of a natural chimney effect and/or in an artificially controlled manner, depending on seasonal/daily requirements, so to improve overall thermo-energetic performance.
- Ventilated facades are generally mounted by means of a framework which comprises upright profiled bars which are fixed to the brick wall in a vertical arrangement, for example by means of brackets.
- the cladding panels are anchored to said uprights in various ways.
- glues being specifically designed for applications of this kind, their properties are greatly influenced by the environmental conditions present at the moment of the gluing step, particularly the temperature and degree of humidity.
- favourable environmental condition not always present and varying within the same working day, are required for the laying of the panels.
- the installation of the panels may therefore take a very long time given the impossibility of working continuously in any environmental condition.
- an alternative method of attachment envisages retaining the panels by means of support brackets fixed to the uprights with bolts and/or rivets.
- the bolts and rivets have been entirely replaced by springs and hooks fixed to the special profiles.
- One example of an attachment system of this type is described in EP1764455A2 . But even this technical solution is not without drawbacks, in particular consisting of the presence of visible hooks and the large number and complexity of the components making up the facade.
- the purpose of the present invention is to propose a cladding structure, in particular a ventilated facade, able to overcome the drawbacks of the attachment systems complained of above.
- FIG. 1 shows a front view of a lower portion of a cladding structure of a wall, at the last two panels of a vertical row of panels, with the latter seen in transparency.

- FIG. 12 shows a front view of a lower portion of a cladding structure of a wall using the panels in figure 10 , at the last four panels of two adjacent vertical rows of panels.
- reference numeral 1 denotes a part, in particular a lower part, of a cladding structure of a wall.
- vertical and “upper/lower” will refer, save as specified otherwise, to planes parallel to that of the wall to be clad;
- rear or “inner” and “front” or “outer” will refer, save as specified otherwise, to sides or surfaces of the panels or of other elements of the cladding structure respectively facing the wall to be clad or facing outwards.
- the structure comprises a support frame 10 suitable for being fixed to a wall to be clad and a plurality of cladding panels 20 suitable for being anchored to said support frame.
- the frame 10 comprises at least two vertical upright profiled bars 12.For example said upright profiled bars 12 can be anchored to the wall by anchorage brackets (not shown).
- the upright profiled bars 12 have a "T",”L”, “H” or similar shape section, so as to define, on the side opposite the wall, a vertical abutment plane 14.
- a vertical row of cladding panels 20 is fixed to a pair of upright profiled bars 12 ( figure 1 ).
- a frame composed therefore of a plurality of upright profiled bars 12 parallel to each other, permits the assembly of various vertical rows of panels 20, next to each other ( figure 4 ).
- the panels 20 of two adjacent vertical rows, as shown in figure 4 can be fixed to the vertical abutment plane 14 of a single upright profiled bar 12.
- a pair of upper anchorage plates 22 and a pair of lower retention plates 24 are fixed to the inner side of each cladding panel 20.
- Said upper 22 and lower plates 24, for example metallic plates, are fixed near the lateral rims of the panel 20, at the abutment plane 14 of the upright profiled bars 12.
- the upper anchorage plates 22 have respective end portions 22' projecting from the upper rim of the panel 20 and suitable for being each fixed to a respective upright profiled bar 12 by means of mechanical anchorage means.
- end portions 22' have a hole 23 for the attachment of the upper plates 22 to the frame by rivets 26.
- the lower retention plates 24 project from the lower rim of the panel 20 so as to be engaged by an underlying panel.
- the lower retention plates 24 have respective end portions 24' which, once the panel has been fixed to the support frame 10, extend behind the inner side of the underlying panel, that is to say are surmounted by the upper rim of said panel.
- the lower plates 24 While the upper plates 22 perform the function of anchoring the panel to the support frame 10, the lower plates 24 have a function of resistance to the pressure/negative pressure load of the air circulating in the cavity or air space between the panels and the wall. In other words, the interaction of the lower plates 24 and the underlying panel counters the tendency of the panel to detach from the support frame in the lower part which is not mechanically fixed to the frame but merely rests on the vertical abutment plane 14.
- the lower plates 24 may be horizontally staggered in relation to the upper plates 22 so as not to interfere with the upper plates 22 of the underlying panel.
- the vertically adjacent cladding panels 20 may be fitted on the support frame in such a way as to be separated by a horizontal clearance channel 11.
- the upper anchorage plates 22 may be fixed to the respective uprights 12 at said clearance channel 11. This way, in fact, it proves easy to access the mechanical anchorage means, such as the rivets 26, to release or remove them and thereby dismantle a single panel without having to remove those above it.
- the lower retention plates 24 of one panel overlap the underlying panel to a lesser extent than the height of the clearance channel 11, in such a way that the lower plates of a panel released from the upright profiled bars and pushed towards the upper panel disengage from the underlying panel.
- the panel can thus be conveniently extracted from a row of panels.
- the facade thereby proves entirely and conveniently accessible for inspection, for example so as to perform maintenance, and single panels may be easily replaced in case of deterioration.
- the upper 22 and lower plates 24 may be glued to the inner side of the panel 20.
- a structural glue 50 is used, for example of the polyurethane type.
- the upper anchorage plates 22 and lower retention plates 24 may be glued to the respective panels before transport of the panels to the building site where the cladding structure is being installed, so as to guarantee all the panels, optimal thermo-hygrometric conditions during the gluing phase.
- the installer receives the panels on site already pre-assembled with their anchorage and retention plates and once the support frame has been mounted, his work consists merely of positioning the panels along the uprights and in fixing them mechanically by means of the anchorage plates only.
- the only possible use of the glue on site is envisaged for the corner panels, the uprights of which are completed concealed and to which mechanical connection is therefore not possible.
- the assembly of the panels is therefore rapid and easy, but above all is not influenced by environmental conditions.
- the attachment system shown does not require the use of upright profiled bars having a specific cross-section, nor of support hooks of the panels, nor of other specific anchorage devices.
- the upright profiled bars have a traditional "T" section and the anchorage and retention plates are normal metal plates of a rectangular shape. Consequently, both the production costs of the attachment system of the panels and the installation times of the cladding structure are less than the costs and times envisaged for other attachment systems.
- the structural glue 50 is able to absorb not only any vibrations of the panels but also all the dilations of the uprights, which are for example in aluminium, caused by the temperature range.
- a safety net 60 may be attached, for example in fibre glass, suitable for retaining any pieces of panel which could otherwise detach and fall in the event of accidental breakage of a panel, using for example a bicomponent polyurethane glue.
- each upper anchorage plate 220 is fixed, as well as by the glue 50, also mechanically to the inner side of the panel 20, for example by means of rivets or bolts.
- each upper anchorage plate 220 comprises a transversal portion 221 which extends horizontally towards the median vertical axis of the panel so as to terminate externally in relation to the space occupied by the upright profiled bar 12.
- the end of said transversal portion 221 being fixed to the panel, for example by a bolt 224 which screws onto a plug 225 embedded in the thickness of the panel.
- the panels 100 of the lowest horizontal row of the facade may have the lower retention panels 240 not protruding from the lower rim of the panel, there being no underlying panel which can retain them.
- These lower plates 240 can be glued or mechanically fixed to the upright profiled bars.
- at least one of the lower plates 240 is horizontally orientated and has an end portion 240' protruding from the lateral rim of the panel to be mechanically anchored to the respective upright profiled bar 12, for example by means of a rivet 26, as shown in figures 1 , 4 , 5 and 6c .
- Figures 1 and 4 for example show a lower panel 100 with both lower retention plates 240 orientated horizontally and projecting from the lateral rim of the panel 100 for their attachment by means of rivets 26 to the upright profiled bars 12.Note how the two lower plates 24 are horizontally staggered in relation to each other so as not to interfere with the upper plates 240 of the horizontally adjacent panels. Figure 4 shows how, for these horizontally positioned lower retention plates 240 too, the rivet 26 is applied at the horizontal clearance channel 11' which separates vertical rows of panels.
- FIG 4 also shows a corner panel 101.
- the left rim of such panel 101 fully conceals the relative upright profiled bar 12.
- the lower left corner of said panel 101 may be directly anchored to the upright profiled bar 12 by means of the structural glue 50.
- the panel 20 differs from the panel shown in figure 2 in that, in place of the two upper anchorage plates 22, a single upper anchorage plate 322 having a horizontal end portion 322' projecting from the upper rim of the panel 20 and suitable for being fixed to the upright profiled bars 12 by means of mechanical anchoring means, such as rivets 26, is used.
- the panel is fitted with the same lower retention plates described in the previous figures.
- the anchorage plate 322 has a pair of vertical slits 323 at the top in each of which the lower end portion of a respective lower retention plate 24 is inserted, so as to permit said lower retention plates 24 to be engaged by an underlying panel.
- the anchorage plate 322 is fixed to the respective panel 20 by glue and/or by mechanical attachment means, such as screws 325.
- the variant with anchorage plate 322 makes it possible, thanks to the horizontal end portion 322', to close the horizontal clearance channel 11 separating vertically adjacent cladding panels, at the back. This way dirt, insects or other foreign bodies can be prevented from getting inside the cavity between the wall and the cladding through said clearance channel.
- the idea of the present invention is to combine the advantages of using glue, making it possible to use few, simple structural elements, with those of mechanical attachment, which ensures maximum safety and reliability over time, having eliminated however the aforementioned drawbacks of using glue on site and at the same time limiting the use of mechanical attachments, such as rivets, to the bare minimum and concealing such attachments means from sight.
Description
- The present invention relates to a cladding structure of a wall using panels or slabs, such as mineral slabs of ceramic, hard stone, marble, granite and the like, in particular for the realisation of ventilated facades.
- As is known, a ventilated facade is taken to mean a cladding of a vertical wall, for example in brick, generally achieved with panels mounted at a certain distance from such wall, so as to create an air space between the wall and the cladding. The space between the cladding and the wall is designed in such a way that the air present in it can flow by means of a natural chimney effect and/or in an artificially controlled manner, depending on seasonal/daily requirements, so to improve overall thermo-energetic performance.
- Ventilated facades are generally mounted by means of a framework which comprises upright profiled bars which are fixed to the brick wall in a vertical arrangement, for example by means of brackets. The cladding panels are anchored to said uprights in various ways. For example, it is known of to fix the panels to the uprights by means of structural glues. Despite such glues being specifically designed for applications of this kind, their properties are greatly influenced by the environmental conditions present at the moment of the gluing step, particularly the temperature and degree of humidity. For this reason, favourable environmental condition, not always present and varying within the same working day, are required for the laying of the panels. The installation of the panels may therefore take a very long time given the impossibility of working continuously in any environmental condition.
- Attempts have been made to overcome this drawback by eliminating entirely the use of glue and fixing the panels to the uprights using solely mechanical means. For example, an alternative method of attachment envisages retaining the panels by means of support brackets fixed to the uprights with bolts and/or rivets. This technical solution, as well as having the drawback that the continuity of the outer cladding surface is interrupted by the presence of hooks, at least from close-up, also proves complex and awkward for the installer. To facilitate the work of the installer, the bolts and rivets have been entirely replaced by springs and hooks fixed to the special profiles. One example of an attachment system of this type is described in
EP1764455A2 . But even this technical solution is not without drawbacks, in particular consisting of the presence of visible hooks and the large number and complexity of the components making up the facade. - Another cladding is known from
US 1 940 141 . - The purpose of the present invention is to propose a cladding structure, in particular a ventilated facade, able to overcome the drawbacks of the attachment systems complained of above.
- Such purpose is achieved by a cladding structure according to
claim 1 and by a cladding panel according toclaim 10. The dependent claims show preferred or advantageous embodiments of the cladding structure. - Further characteristics and advantages of the structure according to the invention will be more clearly comprehensible from the description given below of its preferred and non-limiting embodiments, with reference to the appended drawings, wherein
figures 10 to 12 show the invention, whereasfigures 1 to 9 are to support the understanding of the invention. - -

Figure 11 shows a front view of a lower portion of a cladding structure of a wall using the panels infigure 10 , at the last two panels of a vertical row of panels; and - -
Figure 12 shows a front view of a lower portion of a cladding structure of a wall using the panels infigure 10 , at the last four panels of two adjacent vertical rows of panels. - In said
drawings reference numeral 1 denotes a part, in particular a lower part, of a cladding structure of a wall. Hereinafter in the description, the term "vertical" and "upper/lower" will refer, save as specified otherwise, to planes parallel to that of the wall to be clad; the terms "rear" or "inner" and "front" or "outer" will refer, save as specified otherwise, to sides or surfaces of the panels or of other elements of the cladding structure respectively facing the wall to be clad or facing outwards. - The structure comprises a
support frame 10 suitable for being fixed to a wall to be clad and a plurality ofcladding panels 20 suitable for being anchored to said support frame. Theframe 10 comprises at least two vertical upright profiled bars 12.For example said upright profiledbars 12 can be anchored to the wall by anchorage brackets (not shown). - In one embodiment, the upright profiled
bars 12 have a "T","L", "H" or similar shape section, so as to define, on the side opposite the wall, avertical abutment plane 14. The depth of the upright profiledbars 12, that is to say the perpendicular extension to thevertical abutment plane 14, substantially defines the depth or breadth of the cavity or air space which is created between the cladding panels and the wall. - A vertical row of
cladding panels 20 is fixed to a pair of upright profiled bars 12 (figure 1 ). A frame, composed therefore of a plurality of upright profiledbars 12 parallel to each other, permits the assembly of various vertical rows ofpanels 20, next to each other (figure 4 ). Thepanels 20 of two adjacent vertical rows, as shown infigure 4 , can be fixed to thevertical abutment plane 14 of a single upright profiledbar 12. - A pair of
upper anchorage plates 22 and a pair oflower retention plates 24 are fixed to the inner side of eachcladding panel 20. Said upper 22 andlower plates 24, for example metallic plates, are fixed near the lateral rims of thepanel 20, at theabutment plane 14 of the upright profiledbars 12. - The
upper anchorage plates 22 have respective end portions 22' projecting from the upper rim of thepanel 20 and suitable for being each fixed to a respective upright profiledbar 12 by means of mechanical anchorage means. For example such end portions 22' have ahole 23 for the attachment of theupper plates 22 to the frame byrivets 26. - The
lower retention plates 24 project from the lower rim of thepanel 20 so as to be engaged by an underlying panel. In other words, thelower retention plates 24 have respective end portions 24' which, once the panel has been fixed to thesupport frame 10, extend behind the inner side of the underlying panel, that is to say are surmounted by the upper rim of said panel. - While the
upper plates 22 perform the function of anchoring the panel to thesupport frame 10, thelower plates 24 have a function of resistance to the pressure/negative pressure load of the air circulating in the cavity or air space between the panels and the wall. In other words, the interaction of thelower plates 24 and the underlying panel counters the tendency of the panel to detach from the support frame in the lower part which is not mechanically fixed to the frame but merely rests on thevertical abutment plane 14. - The
lower plates 24 may be horizontally staggered in relation to theupper plates 22 so as not to interfere with theupper plates 22 of the underlying panel. - The vertically
adjacent cladding panels 20 may be fitted on the support frame in such a way as to be separated by ahorizontal clearance channel 11. Theupper anchorage plates 22 may be fixed to therespective uprights 12 at saidclearance channel 11. This way, in fact, it proves easy to access the mechanical anchorage means, such as therivets 26, to release or remove them and thereby dismantle a single panel without having to remove those above it. - To such purpose, the
lower retention plates 24 of one panel overlap the underlying panel to a lesser extent than the height of theclearance channel 11, in such a way that the lower plates of a panel released from the upright profiled bars and pushed towards the upper panel disengage from the underlying panel. The panel can thus be conveniently extracted from a row of panels. - The facade thereby proves entirely and conveniently accessible for inspection, for example so as to perform maintenance, and single panels may be easily replaced in case of deterioration.
- The upper 22 and
lower plates 24 may be glued to the inner side of thepanel 20. To such purpose astructural glue 50 is used, for example of the polyurethane type. - The
upper anchorage plates 22 andlower retention plates 24 may be glued to the respective panels before transport of the panels to the building site where the cladding structure is being installed, so as to guarantee all the panels, optimal thermo-hygrometric conditions during the gluing phase. - Consequently, the installer receives the panels on site already pre-assembled with their anchorage and retention plates and once the support frame has been mounted, his work consists merely of positioning the panels along the uprights and in fixing them mechanically by means of the anchorage plates only. The only possible use of the glue on site is envisaged for the corner panels, the uprights of which are completed concealed and to which mechanical connection is therefore not possible. The assembly of the panels is therefore rapid and easy, but above all is not influenced by environmental conditions.
- It should be emphasised that the attachment system shown does not require the use of upright profiled bars having a specific cross-section, nor of support hooks of the panels, nor of other specific anchorage devices. In the example illustrated, the upright profiled bars have a traditional "T" section and the anchorage and retention plates are normal metal plates of a rectangular shape. Consequently, both the production costs of the attachment system of the panels and the installation times of the cladding structure are less than the costs and times envisaged for other attachment systems.
- It should also be noted that the
structural glue 50 is able to absorb not only any vibrations of the panels but also all the dilations of the uprights, which are for example in aluminium, caused by the temperature range. - As shown in
figure 3 , on the rear side of the cladding panel asafety net 60 may be attached, for example in fibre glass, suitable for retaining any pieces of panel which could otherwise detach and fall in the event of accidental breakage of a panel, using for example a bicomponent polyurethane glue. - In
figures 7-9 , for example envisaged for particularly extensive and therefore heavy panels, theupper anchorage plates 220 are fixed, as well as by theglue 50, also mechanically to the inner side of thepanel 20, for example by means of rivets or bolts. To such purpose, so as not to influence the dimensions of the structure, eachupper anchorage plate 220 comprises atransversal portion 221 which extends horizontally towards the median vertical axis of the panel so as to terminate externally in relation to the space occupied by the upright profiledbar 12. The end of saidtransversal portion 221 being fixed to the panel, for example by abolt 224 which screws onto aplug 225 embedded in the thickness of the panel. - The
panels 100 of the lowest horizontal row of the facade may have thelower retention panels 240 not protruding from the lower rim of the panel, there being no underlying panel which can retain them. Theselower plates 240 can be glued or mechanically fixed to the upright profiled bars. In this second case, at least one of thelower plates 240 is horizontally orientated and has an end portion 240' protruding from the lateral rim of the panel to be mechanically anchored to the respective upright profiledbar 12, for example by means of arivet 26, as shown infigures 1 ,4 ,5 and6c .Figures 1 and4 for example show alower panel 100 with bothlower retention plates 240 orientated horizontally and projecting from the lateral rim of thepanel 100 for their attachment by means ofrivets 26 to the upright profiled bars 12.Note how the twolower plates 24 are horizontally staggered in relation to each other so as not to interfere with theupper plates 240 of the horizontally adjacent panels.Figure 4 shows how, for these horizontally positionedlower retention plates 240 too, therivet 26 is applied at the horizontal clearance channel 11' which separates vertical rows of panels. - Such
figure 4 also shows acorner panel 101. As may be noted, the left rim ofsuch panel 101 fully conceals the relative upright profiledbar 12. In this case, the lower left corner of saidpanel 101 may be directly anchored to the upright profiledbar 12 by means of thestructural glue 50. - In the invention illustrated in
figures 10-12 , thepanel 20 differs from the panel shown infigure 2 in that, in place of the twoupper anchorage plates 22, a singleupper anchorage plate 322 having a horizontal end portion 322' projecting from the upper rim of thepanel 20 and suitable for being fixed to the upright profiled bars 12 by means of mechanical anchoring means, such asrivets 26, is used. - At the bottom, the panel is fitted with the same lower retention plates described in the previous figures.
- The
anchorage plate 322 has a pair ofvertical slits 323 at the top in each of which the lower end portion of a respectivelower retention plate 24 is inserted, so as to permit saidlower retention plates 24 to be engaged by an underlying panel. - In one embodiment, the
anchorage plate 322 is fixed to therespective panel 20 by glue and/or by mechanical attachment means, such as screws 325. - Compared to
figures 1-9 , the variant withanchorage plate 322 makes it possible, thanks to the horizontal end portion 322', to close thehorizontal clearance channel 11 separating vertically adjacent cladding panels, at the back. This way dirt, insects or other foreign bodies can be prevented from getting inside the cavity between the wall and the cladding through said clearance channel. - In short, the idea of the present invention is to combine the advantages of using glue, making it possible to use few, simple structural elements, with those of mechanical attachment, which ensures maximum safety and reliability over time, having eliminated however the aforementioned drawbacks of using glue on site and at the same time limiting the use of mechanical attachments, such as rivets, to the bare minimum and concealing such attachments means from sight.
- A person skilled in the art may make modifications, adaptations and replacements of elements with others functionally equivalent to the embodiments of the cladding structure according to the invention so as to satisfy contingent requirements, while remaining within the sphere of protection as defined by the following claims. Each of the characteristics described as belonging to a possible embodiment may be realised independently of the other embodiments described.
