Definitions

  • the present invention relates to a new and special manufacturing process that is suitable for making cheaper the manufacture of known devices used in the formation of so-called "continuous facades" for supporting and fixing at respective points of application the sheets of glass used to form their relative cladding.
  • continuous facades As is known for the external cladding of facades of buildings, it is today very widespread and becoming increasingly common to apply to them glass sheets in order to obtain facades developing totally glassed surfaces formed in other words of a continuous surface of glass sheets, hence the definition "continuous facades".
  • the one that is quite widespread and quite widely used is the one that involves the use of particular metal parts that are suitable for fixing and supporting corresponding glass sheets on an appropriate application structure.
  • the complete conformation of such devices substantially consists of an appropriately formed central body from which four arms appropriately shaped and substantially the same as one another lead away in a coplanar manner facing radially outwards and are arranged orthogonally divaricated symmetrically to one another,.
  • the resulting shape of these devices has a similar conformation to that of a four-legged spider, and has led to the definition of "spider glass" used in the specific field to defme also the relative applicational technique.
  • spikeder glass used in the specific field to defme also the relative applicational technique.
  • in addition to the conformation fundamentally comprising, as said, four arms in practical use also reduced elements are used comprising only three, two or even a sole arm.
  • the corresponding devices used for the formation of a continuous facade are first fixed at suitable points of a corresponding applicational structure by means of suitable fixing means engaged in the respective central bodies, then on the free end of the corresponding arms articulated joints are fixed that are in turn fixed in corresponding holes made in appropriate points of respective glass sheets that are thus fixed to and supported on said application structure.
  • the devices in question are subjected to mechanical stress generated by the weight of the glass sheets and the thrust produced on them by the action of the wind, which as is known are overall considerable.
  • the structure of such devices in order to withstand with the necessary security the action of the aforementioned mechanical stress, is obviously made of materials with high mechanical resistance characteristics.
  • the material that is normally used to produce these devices is steel, in particular a suitable stainless steel that not only has good mechanical resistance characteristics but is not subject to undesirable rusting phenomena to which it would be subject through the action of the atmospheric agents to which the aforementioned devices are subject.
  • steel in particular stainless steel
  • the cost of steel, particularly stainless steel is rather high and its relative specific weight is also high, the devices manufactured with this metal are overall significantly costly. Consequently, other materials such as aluminium and some of its alloys have been tried together with particular implementing techniques to produce devices of the aforementioned type, but the elements thereby obtained, although they are cheaper than those in steel all have limited mechanical resistance characteristics so that their production is limited as their scope is limited to few and particular applications that involve only limited stress.
  • said central body 11 of the device in the conformation to which reference is made, consists of a plate 11a with a substantially rectangular form and considerable thickness that at its greater sides is connected to two short portions 11 b of the same thickness, from the ends of which, as said, said arms 12 lead away.
  • Said plate 11 a is provided along its greater axis with appropriate cylindrical holes 11c in which appropriate elements can be engaged that are normally provided for positioning and fixing the latter and therefore the corresponding device 1 on a corresponding support element 6 of the application structure.
  • said cylindrical holes 11c illustrated by way of example in figure 1 may in practice consist of appropriately slotted and/or threaded holes.
  • the body forming the global element of a device 1 of the type to which reference is made consists of an external body E (see figures 1 and 4) defining the functional/aesthetic conformation of a normal device of the aforementioned type and an internal strengthening structure.
  • figures 1 to 4 inclusive will disclose the particular solution that is achievable with the process in question.
  • this internal strengthening structure is clearly indicated only by a dotted line, its particular conformation is furthermore illustrated even more clearly from the sectioned views shown in figure 4 and in those directly shown in figure 1 on the arms 12. More in detail, always observing the aforementioned figures, it can be seen how this strengthening structure substantially consists of a sheet 21 of limited thickness that in its conformation illustrated by way of example is arranged practically at the centre of the thickness of the relative parts of the body forming the basic element of the device 1 in which it is inserted.
  • said sheet 21 extends centrally to the thickness of the plate 11a with the corresponding part 21 a (see figures 1 and 4) then continues in the same way, inside the short portions 11b with the corresponding parts 2 1 b (see figures 1 and 4) from the free ends of which it then diverges into the corresponding arms 12 with the parts 21c (see transverse sections shown on the arms 12) at the free ends of which (21c) it finally joins the looped bodies 21d.
  • the strengthening structure 2 is totally comprised in the external body E that will cover all its parts with a cladding that in its thinnest parts nevertheless has a minimum thickness of at least 1 or 2 millimetres.
  • the type of stainless steel used to produce said strengthening structure can be advantageously replaced by a non-stainless steel, in fact as the strengthening structure is totally incorporated into the successive aluminium structure, it is totally clad by the latter and is thus insulated and protected from atmospheric agents, so that it can clearly not suffer any oxidation process.
