Definitions

  • the present finding refers to profiles and metal frameworks for panelling.
  • such profiles can make suspended frameworks for supporting suspended ceiling panels or frameworks for vertical wall panels.
  • the profiles must be made light, above all in the case of structures suspended from the ceiling through tension rods. Lightness is also a necessity for cost reasons. This means that it is necessary to keep the thickness of the sheet metal from which they are formed low. However, this brings about risks of yielding under load. For example, in suspended ceiling structures, since the profiles are suspended with spaced tension rods along the profile, there is the risk that the profile bends in the suspension points, twisting and, in the worst case scenario, causing the entire structure to collapse.
  • CA 2568111 describes C-shaped profiles for frames that are equipped with short transversal ribs on a single face or else formed with larger V-shaped ribs or else with ribs that make a complete surface grid.
  • the distance between the ribs is great (much greater than the thickness of the individual rib) and the surface of the profile between the ribs is flat.
  • Such solutions also do not lead to optimal results.
  • especially with the first two forms of ribs there is transversal strengthening, but yielding points are produced that can cause the structure to collapse and curve along the extension of the profile.
  • the general purpose of the present finding is to avoid the aforementioned drawbacks by providing profiles for making frames for panelling with improved characteristics.
  • the corrugations have a depth from crest to trough of between 0.1 and 10 times the thickness of the sheet metal and, in particular, between 0.1 and 3.
  • the corrugation pitch can advantageously be between 2 and 20 times the thickness of the sheet metal and, in particular, between 2 and 10.
  • the framework can comprise profiles fixed according to a grid with parallel and transversal profiles.
  • the grid advantageously comprises elements for fastening the grid to a ceiling through spaced tension rods.
  • figure 1 shows a panelling structure, in particular for suspended ceilings, generically indicated with 10 and formed by a plurality of metallic profiles 11 arranged to form a framework that defines an attachment plane for the panelling 15 (partially schematically represented).
  • the profiles can, for example, be arranged fixed according to a grid with parallel and transversal profiles.
  • crossed elements as shown in the figures, there can be known elements 12 (easily imagined by the man skilled in the art) for fastening together at the cross-over points.
  • elements 12 for fastening together at the cross-over points.
  • the structure is generally suspended from the ceiling through fasteners 13 and corresponding tension rods 14.
  • Figure 2 shows a wall structure, comprising vertical C-shaped profiles 11 mounted spaced apart with suitable end profiles fixed to the ceiling and to the floor, so as to form a framework for fixing panels 20.
  • Figure 3 shows an enlarged view of the section of one of the profiles according to the finding and used in the structures of figures 1 and 2 .
  • figure 3 shows a profile 11 in the situation of figure 1 , with the end part of a fastening element 13. Nevertheless, it should be understood that such profiles can also be used to make walls.
  • the profile 11 has a C-shaped cross section, advantageously with upper edges bent inwards to define two ledges 16, 17 used to attach substantially known accessories.
  • the ledges can in turn have their edge advantageously turned inwards to eliminate the sharp edge and promote the attachment of accessories.
  • the suspension accessory 13 can have a known shape for a secure engagement in the ledges 16, 17.
  • the accessory can be made from sheet metal and foresee side seats 18, 19 that receive the ledges when the accessory, after insertion, is rotated in the plane transversal to the profile.
  • other accessories to be engaged in the profile can also have an end similar to the one shown in figure 3 .
  • Known end systems, not shown, can also be used in vertical assembly.
  • the profile is formed from a strip of bent sheet metal corrugated so that the crests and troughs extend parallel to the extension of the profile. In this way, on the walls of the profile, substantially over the entire wall, there is narrow rifling that extends parallel to the direction of extension of the profile.
  • the crests of the corrugations can also be flattened.
  • the depth 'h' between crest and trough of the corrugations prefferably be between 0.1 and 10 times the thickness of the sheet metal and, in particular, around 1.
  • the corrugation pitch (or rifling pitch) is advantageously between 2 and 20 times the thickness of the sheet metal and, in particular, around 7 times the thickness of the sheet metal.
  • Figure 4 shows a variant embodiment of the profile 11 in which the two bent edges make ledges 116, 117 that are curved towards the inside of the profile (instead of being bent at a right angle to be coplanar, like in figure 3 ) to line up matching ends 118, 119 of a suitable accessory 113.
  • Figure 5 shows a portion of a further variant of a C-shaped profile, generically indicated with 211, made according to the invention, with ledges 216 and 217.
  • the ledges can also be configured as shown in the previous embodiments (and vice-versa).
  • Such a profile 211 is formed from a corrugated sheet with corrugations similar to those described earlier to have rifling always extending in the direction of extension of the profile, but that are inclined with respect to the axis of extension of the profile.
  • rifling extending in the direction of extension of the profile should indeed also be understood here to include the case of rifling that is not parallel to the axis of the profile, but that still extends mainly in the direction of extension of the profile, in other words more in the direction of extension of the profile rather than in the direction transversal to such a direction of extension (thus a rifling with inclination of less than 45°).
  • the angle of inclination can in any case be advantageously between 0° (solution described earlier) and 45° and, in particular, between 10° and 30° (preferably, about 20°).
  • the corrugated extension of the walls of the profile 211 remains, in cross section, substantially similar to that of the cross section in the profiles already described above, with a substantially continuous corrugation of crests and troughs.
  • the rifling pitch can be between 2 and 20 times the thickness of the sheet metal
  • the depth of the rifling from crest to trough can be between 0.1 and 10 times the thickness of the sheet metal
  • the radius of the corrugation can be between 0.1 and 5 times.
  • the crests and the walls of the corrugations can also be flattened as a fret.
  • the inclination of the rifling slightly increases the strength of the wings of the profile making them less flexible. This is useful, for example, during the assembly of the profiles and during the insertion of the screws to fix the plasterboard panels.
  • the main advantage is that, surprisingly, there is a substantial increase in fire-resistance of the structure.
  • the time that the structure resists before collapsing substantially increases and can compensate for the lesser fire-resistance that could result from the use of a thinner sheet metal.
