Definitions

  • the present invention relates to a corrugated sheet with a visual effect.
  • the term sheet applies here to any element substantially in the form of a plate, whatever the dimensions and/or the geometry of the latter, for example square, rectangular or other. In all cases, the thickness of such a sheet is of the order of a few millimeters, generally between 0.2 mm and 3 mm.
  • metallic includes any metal, including alloys, suitable for the use of sheet metal, exterior or interior, in aggressive environments or not.
  • the term rib concerns any relief, positive or negative, with respect to the mean plane of the sheet, whatever the geometry of the cross section of the ribs and/or the dimensions and/or the number and/or the distribution ribs on the sheet.
  • Such sheets are used for roofing a building or for cladding, that is to say, for covering the wall of a building, including internal walls. They can be painted or not.
  • the ribbed metal sheets used for roofing are generally monochrome, in particular in order to comply with the architectural regulations existing in certain countries such as France. There is also a monochrome appearance of the sheets when they are used as siding of a building, for example either in a plain color or imitating wood, brick, stone. This being the case, the practice currently encountered ensures a uniform treatment of the whole of the sheet, without differentiation between the ribs and the inter-rib flat zones.
  • EP-A-358495 a corrugated sheet in which the faces of the ribs and the flat areas have various colors in order to provide a different visual appearance depending on the position of the person who is looking in relation to the sheet.
  • the visual aspect varies according to the viewing angle.
  • a ribbed sheet provided with a coating based on pearlescent pigment which gives a changing appearance of the sheet according to the angle of view.
  • none of these solutions creates a trompe l'oeil making it possible to have a different appearance from that of a corrugated sheet.
  • the invention thus proposes a ribbed sheet offering a visual effect different from those usually encountered, on the basis of a polychromy adapted to the reliefs of the sheet.
  • the subject of the invention is a ribbed metal sheet comprising at least two ribs separated by a non-ribbed flat zone, characterized in that the whole of each rib receives at least a given first coating, the whole of each non-ribbed flat zone receiving at least a second coating, the first and second coatings being differentiated and constituting a given visual effect.
  • a visual differentiation of the ribs and the non-ribbed flat zones is carried out based on different colors.
  • a given visual effect for example a trompe-l'oeil by highlighting a given aspect of reliefs or flat areas.
  • At least one of the coatings is complex and combines a color with a granite or grooved appearance.
  • At least one of the coverings is a prefabricated strip.
  • FIG.1 is a partial view, in perspective from the visible upper face, of a corrugated sheet metal according to one embodiment of the invention.
  • the figure 1 illustrates, partially, a ribbed metal sheet 1.
  • This is a steel metal sheet.
  • the sheet is made of another metal, an alloy or a composite material.
  • Such a sheet 1 generally has a rectangular shape, it being understood that it can be square.
  • Sheet 1 is ribbed.
  • the ribs 2 are all identical, parallel and regularly distributed over the sheet.
  • the ribs 2 are provided over the entire length of the sheet 1, therefore according to its largest dimension.
  • the ribs present on the sheet are not all identical and/or are not distributed regularly. Likewise, they can be arranged on a part of the sheet and/or according to its smallest dimension.
  • the ribs are located below a mean plane P of the sheet 1, or alternatively above and below the mean plane P of the sheet 1.
  • the ribs 2 here all have, in cross section, a trapezoidal shape. They are separated by a flat zone 3 of the sheet.
  • the flat areas 3 define the mean plane P of the sheet 1.
  • the flat top 4 of each rib 2 is parallel to the plane P, therefore to the flat areas 3.
  • the sides 5, 6 of each rib 2 are inclined so that the open base 7 of each rib 2 has an area greater than that of the top 4 of the rib 2 concerned.
  • the flat areas 3 and each rib 2. present a differentiated coating, respectively R2, R3.
  • the top 4 and the sides 5, 6, which is coated identically by the coating R2, namely a given color.
  • the coating may be different between the various constituent parts 4 to 6 of a rib 2.
  • the coating consists of a given color R2, providing a particular visual appearance, for example imitating wood or another material.
  • the coating can be complex, associating one or more colors with a granite, grooved or other appearance.
  • the flat areas 3 are provided with a coating R3 different from that R2 of the ribs 2 and chosen to provide a visual contrast and/or a given visual appearance, for example a trompe-l'oeil over the entire sheet 1.
  • the flat areas 3 are of a uniform, dark color R3, or even black, in order to give the optical illusion that wooden ribs are fixed on the wall of the building equipped with the sheet 1, this without the flat areas 3 stand out visually.
  • there is a differentiation by color between the ribs and the flat areas so that visually the ribs seem for example independent because in another material, flat areas.
  • the visual effect relates to the largest dimension of the sheet 1, the ribs 2 and flat areas 3 having their respective coating over their entire length.
  • the coatings R2, R3 of the ribs 2 and flat zones 3 concern only part of the length of the latter, or even discontinuously, in dotted lines.
  • a visual effect of the sheet is produced in two dimensions, like a grid.
  • the choice of coatings R2, R3 is such that it is the flat zones 3 which stand out visually with respect to the ribs 2.
  • the visual appearance does not is not that, uniform, of a sheet, only certain areas, the ribs or the flat areas, being highlighted.
  • Such a sheet is obtained either by placing the coating R2, R3 of the ribs 2 and flat areas 3 on a finished sheet, for example by painting, depositing a polymer film, colored or having a given appearance. , for example with microreliefs, or by gluing prefabricated strips corresponding to the desired coating R2, R3, in terms of color and/or appearance.
  • coatings R2, R3 are applied which, on a finished sheet 1, will form the coatings R2, R3 of ribs 2 and flat zones 3, this according to parallel strips between them and over the entire length of the metal strip.
  • the ribs and therefore the flat areas are shaped by bending.
  • the metal strip is then cut into sections whose dimensions correspond to those of a sheet 1.
  • the longevity of the sheet is improved, the coatings R2, R3 having a protective role against aging in air and/or against shocks.
