Definitions

  • the invention relates to a facade cladding profile comprising a base profile made of plastic, in particular made of an extruded plastic, a visible surface, an adjoining shadow gap area, and a fastening strip, in particular which adjoins the shadow gap area, the visible area being formed by a plastic film attached to the basic profile, and the shadow gap surface is designed differently than the visible surface of the facade cladding profile.
  • Such a facade cladding profile or panel made of plastic is preferably in one piece with respect to the basic profile and can be produced in profile form by means of continuous casting or extrusion.
  • Thermoplastics in particular PVC (polyvinyl chloride), are preferably used as the plastic material for the base profile.
  • PVC is z. B. also used in window frame construction or for pipes.
  • the PVC material is preferably thermally melted in granular form and pressed through a mould.
  • the PVC slowly cools down and retains its shape.
  • the forms can have the most diverse contours.
  • a basic profile usually has hollow chambers which are delimited by webs, the cross section remaining the same in the direction of longitudinal extension.
  • Cladding profiles of the type mentioned are known from the prior art. These are used, for example, to cover the facades of buildings or mobile homes.
  • a substructure arranged on the wall of the building for example made of wood, is provided, on which the facade cladding profiles, in particular which can be several meters long, are attached.
  • the facade cladding profiles include a visible surface and an adjoining shadow gap area, which in turn is adjoined by a fastening strip.
  • the height of the shadow gap surface is lower than that of the visible surface, ie the shadow gap surface is at a lower level than the visible surface.
  • the same preferably also applies to the fastening strip opposite the shadow gap surface and/or the visible surface.
  • the fastening strip can preferably have several openings arranged one behind the other in the direction of longitudinal extension, which serve to accommodate fastening means, e.g. nails or screws, with the aid of which the individual facade cladding profiles made of plastic can be fastened to the substructure on the wall, e.g. of a building.
  • fastening means e.g. nails or screws
  • the fastening bar is not only used to connect the cladding profiles to the substructure on the wall of a building, but by means of the fastening bar and a corresponding receiving groove, two such cladding profiles can be connected to one another in the manner of a tongue and groove connection.
  • the fastening strip extends on one side of the cladding profile over the length of the cladding profile;
  • a corresponding receiving groove runs on the opposite longitudinal edge of the facade cladding profile.
  • the visible surface of the facade cladding profiles can be designed in many different ways. It is Z. B. known to form the visible surface by film, in particular the film in a desired color is designed and / or has a structure, in particular mimics the look of a wooden surface.
  • the foils are made of PVC.
  • PVC films of this type which have an adhesive layer on one side, are usually not UV-resistant.
  • acrylic In order to make such a film UV-resistant, it is known to coat this film with acrylic.
  • the shadow gap surface can also be formed by a PVC film, which can also be coated with acrylic on the outside, which is glued to a profile web is.
  • the film of the shadow gap surface lies on top of the film on the visible surface, or vice versa. The fact is that the adhesive on the underside of the shadow gap surface film does not stick particularly well to the acrylic coating of the visible surface film or vice versa.
  • the overlapping foil in the present case the foil on the shadow gap, detaches from the top of the foil on the visible surface, off. Gradually, the foil comes off over the entire surface. This is due to the acrylic coating.
  • the utility model offers DE 20 2018 104 844 U1 a solution to provide a different surface, especially with regard to the color design between the visible surface and the shadow gap surface, which is permanently durable. It is required that at least the material of the shadow gap surface has a different color than the visible side of the foil on the visible surface.
  • the shadow joint surface either painted in color or the entire basic profile of a facade cladding profile is made in one piece from the desired colored material for the shadow joint surface, e.g. B. in the extrusion process and the visible surface formed by a glued to the base profile film.
  • expensive color pigments are added to the THERMOPLAST melt for the entire base profile.
  • only the narrow area of the shadow joint surface of the facade cladding profile should be colored, it represents an economic disadvantage to color the entire base profile, which is covered with a film.
  • the object on which the invention is based is to remedy this and to further develop the known prior art.
  • the task is to provide a different surface design, in particular with regard to the color design between the visible surface and the shadow joint surface, which can be produced economically and efficiently from an economic point of view.
  • the shadow joint surface is formed by a coextrusion layer which is materially bonded to the base profile.
  • a coextrusion layer is understood to mean a layer or a layered component of this type which was created by the coextrusion process at the same time as the base body, which was also produced by extrusion is.
  • the coextrusion layer has a different color than the visible side of the plastic film of the visible surface.
  • the basic profile being extruded from a first plastic material and the coextrusion layer made from a second plastic material being coextruded onto the first plastic material of the basic profile, with the first and the second plastic material differing at least in that the second plastic material Achievement of a color other than that of the first plastic material, at least one color pigment is added.
  • the two plastic materials can also be different apart from the color pigment.
  • the coextrusion layer is extruded onto the base profile and is firmly bonded to it.
  • the base profile in particular made from recycled rigid PVC, in particular conventionally gray in color, has a wall thickness that is greater, preferably many times greater, than the wall thickness of the coextrusion layer.
  • the wall thickness of a web of the base profile lying under the coextrusion layer, to which the coextrusion layer is materially attached, can be greater, in particular many times greater, than the wall thickness of the coextrusion layer.
  • the wall thickness of the coextrusion layer is preferably not thicker than necessary for reasons of cost.
  • Complete opacity of the shadow gap surface over the material of the base profile is absolutely necessary for an attractive appearance when the facade is assembled.
  • the base profile on which the coextrusion layer is extruded must not show through the coextrusion layer.
  • the coextrusion layer partially or completely forms a web of the base profile, in particular the coextrusion layer extends over the entire thickness of a web of the base profile, the visible upper side of which forms the shadow joint surface.
  • THERMOPLAST melts which are pressed through the extrusion tool in parallel but with different wall thicknesses, always pose a challenge, as distortions can occur when they cool down.
  • the degree of difficulty is increased again, since the coextrusion layer is provided with color pigments. An even flow line is required. This ensures that, after curing, a dimensionally stable facade cladding profile is created without warping.
  • a raw material that is free-flowing after heating can be used for the coextrusion layer, preferably a raw polymer to which color pigments have been added (e.g. masterbatch).
  • the coextrusion melt prepared in this way makes it possible, especially in combination with a conventional hard PVC melt, to run even different wall thicknesses at the usual extrusion speed and to produce a dimensionally stable facade cladding profile.
  • the height of the shadow joint surface is offset from the visible surface of the plastic facade cladding profile with a sloping edge.
  • the visible surface also extends at least over a large part of the offset edge, ie essentially up to the shadow gap surface. It has been found in this context that the optics when the viewing surface extends from the outer, free end over the offset edge to the shadow gap surface, i.e. ultimately the plastic film also extends from the outer, free end to the shadow gap, the optics are much more attractive than if the offset edge has the same surface as the shadow gap surface.
  • the smooth transition of the coextruded layer with the basic profile is important because only an edgeless surface ensures that the plastic film can be applied continuously and with full adhesion.
  • the plastic film overlaps the transition area between the base profile and the coextrusion layer, in particular by around 4-5 mm.
  • the film edge ends at the apex of the radius of the transition area.
  • the coextrusion layer preferably has a constant wall thickness up to the transition areas in the cross section. In the respective transition area, the wall thickness can decrease towards the end of the coextrusion layer, preferably down to the level of the surface of the basic profile. The wall thickness thus decreases in the direction of the outwardly visible surface of the coextrusion layer.
  • the coextruded layer in the transition area to the fastening strip is covered by the outer end of an added/additional facade cladding profile in the assembled state.
  • two facade cladding profiles can be slid into one another through the fastening strip on one side of a facade cladding profile in a corresponding receiving groove on the opposite, other side of another facade cladding profile in the manner of a tongue and groove connection, so that the fastening strip can be pushed through the receiving groove in the Longitudinal edge of the adjacent profile is covered.
  • a facade surface consisting of at least two mounted facade cladding profiles completely covers the shadow gap with the coextrusion layer as a shadow gap area and not only creates a visually appealing look, but also a weather-resistant surface.
  • the facade cladding profile 10 shown in cross section has a visible surface 12, the visible surface 12 extending from the outer, free end to the shadow joint surface 13.
  • the visible surface 12 is formed in that a plastic film 19 is glued onto the base profile 20 and forms this visible surface 12 with its visible side 19a pointing outwards.
  • the shadow gap surface 13 in turn finds its continuation in the fastening strip 15.
  • the transition between the visible surface 12 and the shadow gap surface 13 is designed as a sloping, offset edge 17.
  • the film 19 is preferably designed as a colored and/or structured PVC film, coated with acrylic, PVDF or other sealing materials in particular on the visible side 19a, and extends from the outer end 11 of the facade cladding profile 10 over the offset edge 17 to the Shadow gap surface 13 approach.
  • the shadow joint surface 13 is contrasted in color with respect to the visible surface 12 of the facade cladding profile. This effect is produced by the extruded coextrusion layer 21, which preferably extends over the entire width of the shadow joint surface 13 and this Shadow joint surface 13 forms and more preferably ends in end-side radii in edgeless, preferably flowing and preferably drop-shaped transitions 22a, 22b.
  • the fastening strip 15 can preferably have a plurality of openings 15a arranged one behind the other in the longitudinal direction of the facade cladding profile, which are used to receive fastening means, e.g. nails or screws, in order to attach the facade cladding profiles to the substructure on the wall of a building.
  • the facade cladding profile 10 also has a receiving groove 16, which serves to accommodate the fastening strip 15 of another facade cladding profile in the manner of a tongue and groove connection.
  • the Figure 1a shows the shadow joint surface 13, which is formed by a coextrusion layer 21, in detail according to FIG figure 1 .
  • the wall thickness d of the coextrusion layer 21 is preferably less than the wall thickness D of the underlying web of the basic profile 20 to which the coextrusion layer 21 is materially attached by coextrusion.
  • the entire web or a partial area of the web of the facade cladding profile, the visible outside of which forms the shadow gap surface 13, is made entirely of the material of the coextruded layer 21 in terms of thickness.
  • This web or partial area of the web as a whole is then coextruded with the extruded base body 20 of the facade cladding profile.
